The liquid ejecting unit 21 moves together with the carriage 22, and ejects the liquid supplied from the liquid container 20 placed in the housing 13 onto the medium, thereby printing on the medium. In another embodiment, the liquid ejecting section 21 may be a line head whose position is fixed without reciprocating.

In the present embodiment, a direction intersecting a movement path when the housing 13 is attached to the housing accommodating portion 14 is a width direction, and a direction in which the movement path extends is a depth direction. Preferably, the movement path intersects the width direction at right angles. The width direction and the depth direction are substantially along a horizontal plane. In the drawing, the direction of gravity when the liquid ejecting apparatus 11 is in a normal use state of being placed on a horizontal plane is indicated by the Z axis, and the moving direction when the housing 13 is attached to the housing accommodating portion 14 is indicated by the Y axis. The moving direction may be referred to as an attaching direction or an inserting direction to the housing accommodating portion 14, and the opposite direction to the moving direction may be referred to as a removing direction. The width direction is indicated by an X axis orthogonal to the Z axis and the Y axis. The width direction, the gravity direction, and the mounting direction intersect with each other, and are directions indicating the length of the width, the height, and the depth, respectively. Further, the width direction, the gravity direction, and the mounting direction preferably intersect so as to be orthogonal to each other.

In the following description, the liquid ejecting apparatus 11 is in a normal use state unless otherwise specified. A direction parallel to the Z axis is referred to as a Z direction, a direction in the Z direction which is the same as the direction of gravity is referred to as a + Z direction, and a direction opposite to the direction of gravity is referred to as a-Z direction. The direction parallel to the Y axis is referred to as the Y direction, one of the Y directions is referred to as the + Y direction, and the other direction is referred to as the-Y direction. A direction parallel to the X axis is referred to as an X direction, one of the X directions is referred to as a + X direction, and the other direction is referred to as a-X direction. The + Y direction is a moving direction of the housing 13 when the housing 13 is inserted into the housing accommodating portion 14.

Fig. 2 is a schematic perspective view of the housing accommodating portion 14. The housing accommodating portion 14 is an accommodating space capable of accommodating one or more housings 13. In the present embodiment, the case housing portion 14 can house four cases 13. A frame 24 is disposed on the-Y direction side of the housing accommodating section 14. The frame 24 communicates with the housing 14 and has an insertion port 25 for inserting the housing 13 into the housing 14. In order to guide the movement of the housing 13 during attachment and detachment, the frame 24 preferably has a plurality of sets of linear guide rails 26 each having one or more than two convex or concave shapes extending in the depth direction.

The housing 13 is attached to the housing accommodating portion 14 through the insertion port 25 and moves in the + Y direction.

The drive source 35 is constituted by a motor, for example. When the pressure varying mechanism 34 reduces the pressure in the pressure varying chamber through the pressure varying flow path 36 by the driving of the driving source 35, the flexible film is deflected and displaced toward the pressure varying chamber side, and the pressure in the pump chamber is reduced. As the pressure of the pump chamber decreases, the liquid contained in the liquid container 20 is drawn into the pump chamber through the liquid introduction portion 32. This is referred to as "suction driving". When the pressure reduction mechanism 34 releases the pressure reduction in the pressure reduction chamber through the pressure reduction flow path 36, the flexible membrane flexes and displaces toward the pump chamber, and the pressure in the pump chamber rises. Then, as the pressure of the pump chamber rises, the liquid in the pump chamber flows out to the supply pipe 33 in a pressurized state. This is referred to as "discharge driving". The supply mechanism 31 alternately repeats the suction drive and the discharge drive, thereby supplying the liquid from the liquid container 20 to the liquid ejecting section 21.

The main body has a substantially rectangular parallelepiped shape. The width of the main body of the connecting member 61 in the Z direction is smaller than the sum of the widths in the X direction

Width in Y direction. At the tip of the connection member 61, a liquid lead-out port 52, a container side electric connection portion 53, a terminal arrangement portion 53a, a guide recess 53g, and a recognition portion 54 are provided. At the tip of the connecting member 61, a first hole 55b and a second hole 56b are formed so as to sandwich the liquid lead-out port 52 in the width direction.

The front end portion of the housing 13 constitutes an engagement receiving portion 65 that can engage the connection member 61 of the liquid container 20. The engagement receiving portion 65 includes the above-described biasing receiving portions 57 and a notch 65a, and the notch 65a is provided between the biasing receiving portions 57 and is engaged with the insertion portion 58 provided on the connection member 61 of the liquid container 20. The engagement receiving portion 65 includes a first hole 55a and a second hole 56a provided on both sides of the notch 65a in the width direction.

When the liquid container 20 is placed on the housing 13, the first hole 55a of the engagement receiving portion 65 and the first hole 55b of the connection member 61 are aligned in the depth direction, and the second hole 56a of the engagement receiving portion 65 and the second hole 56b of the connection member 61 are aligned in the depth direction. The

first holes

55a and 55b constitute a first receiving portion 55, and the

second holes

56a and 56b constitute a second receiving portion 56. The first hole 55b of the connecting member 61 constitutes a first receiving portion 55 that receives the first positioning portion 45 in the attached state. The second hole 56b of the connecting member 61 constitutes the second receiving portion 56 that receives the second positioning portion 46 in the mounted state. Hereinafter, the first hole 55b is also referred to as a first receiving portion 55b provided in the connecting member 61, and the second hole 56b is also referred to as a second receiving portion 56b provided in the connecting member 61.

The engagement receiving portion 65 of the housing 13 is provided with a plurality of substantially cylindrical guide portions 73 projecting in the guide direction from the bottom plate 67. The "guiding direction" is a direction in which the liquid container 20 moves in and out of the opening 13a of the housing 13, and is a direction intersecting the bottom plate 67 and extending along the side plate 68. In the first embodiment, the Z direction is orthogonal to the bottom plate 67. In the present embodiment, the two guide portions 73 are formed so as to be aligned in the width direction.

The connection member 61 of the liquid container 20 is provided with a plurality of guided portions 72 formed to penetrate in the guiding direction. In the present embodiment, the two guided portions 72 are formed so as to be aligned in the width direction at a position on the-Y direction side of the liquid lead-out port 52 and the holder-side electrical connection portion 53.

The guide portion 73 provided on the housing 13 guides the guided portion 72 provided on the connection member 61 in the guiding direction when the liquid containing body 20 is housed in the housing 13. On the other hand, the guided portion 72 provided on the connection member 61 is guided in the guiding direction by the guide portion 73 provided on the housing 13.

In the present embodiment, the guide portion 73 has a convex shape having a substantially semi-cylindrical shape, and the side surface of the guide portion 73 along the guide direction includes a planar regulating portion 73a located on the distal end side and a curved portion 73b located on the proximal end side of the regulating portion 73 a. The guided portion 72 is formed in a shape having a restricting portion 72a and a curved surface portion 72b so as to follow the shape of the guide portion 73. The regulating

portions

72a and 73a regulate the separation and rotation of the liquid container 20 placed in the housing 13. Further, on the distal end surface of the connecting member 61, a dome-shaped protrusion 75, for example, is formed, at least the corner in the guiding direction of which is chamfered. In addition, an engagement hole 76 that engages with the projection 75 is formed in the end plate 70 of the case 13. In this way, when the liquid container 20 is placed on the housing 13, the user can be given a feeling of engagement completion or a tactile feeling of the housing 13 and the liquid container 20 by the click feeling. The protrusion 75 and the engagement hole 76 of the present embodiment are formed as follows: the liquid outlet port 52 of the connecting member 61 and the notch 65a of the housing 13 are arranged in pairs on both sides in the width direction. The connection member 61 is provided with a handle portion 62. The grip portion 62 is formed of a member different from the main body portion of the connection member 61, and is movable relative to the connection member 61. Specifically, the handle 62 can be moved by being rotated about a rotation shaft 63 provided on the connection member 61. The rotating shaft 63 is formed to be open on both sides in the width direction, and a bottomed semi-cylindrical portion protrudes from the top surface of the connecting member 61. The grip portion 62 has a grip portion 62a gripped by the user. The grip portion 62a is located on the side of the accommodating portion 60 that is farther from the coupling member 61 in the depth direction than the shaft portion 62b that is pivotally supported on the pivot shaft 63. The grip 62 is rotatable between a first posture in which the grip 62a and the pivot 63 are at the same height or the grip 62a is located at a position lower than the pivot 63, and a second posture in which the grip 62a is located at a position higher than the pivot 63. The handle portion 62 may be omitted.

Fig. 6 is a schematic perspective view showing the back side of the housing 13. The back surface of the housing 13 is a surface opposite to the surface on which the liquid container 20 is disposed, and faces in the direction of gravity in the mounted state. An engagement groove 78, into which the locking portion 39 (see fig. 3) of the device-side fixing structure 38 of the connection mechanism 29 is inserted and guided in the-Y direction, is provided on the front end side of the rear surface of the housing 13. The engagement groove 78 has a well-known heart-shaped cam groove structure. The lock portion 39 engages with the engagement groove 78 in a state where a force is applied to the housing 13 in the-Z direction in a state where the housing 13 is housed in the housing portion 14. This restricts the movement of the housing 13 in the housed state in the-Y direction. The engagement groove 78 is also referred to as a "case-side fixing structure 78".

Refer to fig. 5. The housing-side fixing structure 78 is opened in the + Y direction at the front end of the housing 13 for insertion of the receiver-side fixing structure 38. A hollow projection 79 that includes a part of the case-side fixing structure 78 therein and projects in the + Z direction is provided on the end portion on the + Y direction side of the bottom plate 67 of the case 13.

At the lower end of the connecting member 61, a concave portion 77 is provided which is recessed in the-Z direction in the attached state and receives the convex portion 79. The recess 77 is located below the receiver-side electric connection portion 53. In the attached state, since the concave portion 77 and the convex portion 79 are fitted, the positioning accuracy of the housing-side electrical connection portion 53 on the housing 13 can be improved. This improves the electrical connectivity between the container side electrical connection portion 53 and the device side electrical connection portion 40 (see fig. 3) of the connection mechanism 29 when the liquid container 20 is attached to the liquid ejecting apparatus 11.

Here, the connection of the connection structure 51 provided in the mounting body 50 to the connection mechanism 29 will be described with reference to fig. 3 and 4. When the attachment body 50 is inserted into the housing space and the distal end approaches the connection mechanism 29, first, the distal ends of the positioning portions 45 and 6, which have a long protruding length in the removal direction, are engaged with each other so as to enter the receiving portions 55 and 6 of the attachment body 50, and the movement of the attachment body 50 in the width direction is restricted. Since the second receiving portion 56 is an oblong hole of an elliptical shape extending in the width direction, the positioning portion 45 entering the first receiving portion 55 of a circular shape becomes a reference for positioning.

When the mounting body 50 further advances after the positioning portions 45 and 6 are engaged with the receiving

portions

55 and 56, the biasing receiving portion 57 comes into contact with the pressing portion 47b and receives the biasing force of the biasing portion 47 c. The movement of the housing 13 in the-Y direction is restricted by the engagement of the device-side fixing structure 38 with the housing-side fixing structure 78. The liquid introducing portion 32 is inserted into the liquid outlet 52 of the liquid container 20 in the-Y direction, and the internal space 60c of the container 60 of the liquid container 20 communicates with the liquid introducing portion 32. Preferably, the positioning portions 45 and 6 are appropriately fitted to the block 44 of the connection mechanism 29 when the liquid guide is inserted into the correct position in the mounting body 50. On the other hand, when the attachment body 50 is to be attached to an incorrect position, the identification portion 54 does not fit into the block 44, so that the attachment body 50 cannot be further moved inward, and the attachment body 50 is prevented from being positioned before the incorrect attachment portion 32 is connected to the liquid lead-out port 52.

When the mounting body 50 advances in the mounting direction, the device-side electrical connection portion 40 enters the terminal arrangement portion 53a of the mounting body 50, is guided by the guide convex portion 40a through the guide concave portion 53g, is adjusted in position, and comes into contact with the housing-side electrical connection portion 53. Since the housing-side electrical connection portion 53 is inclined toward the-Z direction, it is electrically contacted with the apparatus-side electrical connection portion 40 while receiving a force having at least a component in the + Z direction from the apparatus-side electrical connection portion 40. Thus, the housing-side electrical connection portion 53 is electrically connected to the device-side electrical connection portion 40, and information is transmitted and received between the circuit board and the control device 42. By the housing body-side electric connection portion 53 receiving a force having at least a component in the + Z direction from the apparatus-side electric connection portion 40, the electrical contact state of the housing body-side electric connection portion 53 and the apparatus-side electric connection portion 40 is good. In order to suppress positional displacement of the receptacle-side electrical connection portion 53 and the device-side electrical connection portion 40, one of the first connection structure 51F and the second connection structure 51S, which includes the receptacle-side electrical connection portion 53, is preferably disposed as a first receiving portion 55 to be a reference of positioning. When the liquid lead-out port 52 of the liquid containing body 20 is connected to the liquid introduction portion 32 in a state in which liquid can be supplied, and the containing body side electric connection portion 53 is brought into contact with the apparatus side electric connection portion 40 to be electrically connected, the connection of the connection structure 51 to the connection mechanism 29 is completed. The installation state is a state in which the connection is completed.

Fig. 7 is a schematic structural view of an ink bag as an ink supply to an ink jet printer as viewed from the front. The first ink containing bag 71 has an ink bag operating portion 711. The ink bag operation portion includes a container side electrical connection portion 713 for electrical connection to the printer and a first ink bag outlet 717 in the front surface. As shown in fig. 8, the holder-side electrical connection portion includes a chip 7131 and a chip engagement portion 7132 for fixing the chip. Fig. 9 is a schematic structural view of an ink bag for supplying ink to a printer, as viewed from the back, the operation portion of the ink bag is further provided with a plurality of spacing ribs 716 which are arranged transversely and longitudinally and have different lengths, and the spacing ribs are used for increasing the strength of the operation portion of the ink bag, facilitating the installation of a user and fixing the position relationship between the chip and the printer, so as to establish a stable electrical connection relationship between the ink containing bag and the printer. The ink containing bag also has a grip portion 712 and an ink containing portion 714 that facilitate the user to take and mount the ink bag with a hand. The ink receiving bag has an adapter 715 at the rear for continuous ink supply. Fig. 10 is an enlarged view of the transfer port, and it can be seen that the transfer port is roughly two irregular elliptic cylindrical bodies 1501 with long and short radii, a transfer channel 1502 and a sealing rib 1503 for welding and sealing with the tail of the ink containing bag, and the edge of the sealing rib is a smooth straight line or curve, so that the sealing rib and the ink bag are sealed more tightly. In addition, the adapter cylindrical body can also be rectangular, triangular, rhombic or other irregular shapes;

as shown in fig. 11, is a schematic structural diagram of the adapter portion of the present invention. The adapter 82 includes two adapter pins 821 and an adapter tube 822. The adapter tube is preferably a rubber hose, and can also be a plastic tube, a glass tube, a steel tube and the like. The switching screens include siphunculus 8201, hook portion 8202, handheld portion 8203 and temporarily put portion 8204. When the switching part is connected with the switching port, the through pipe of the switching clamping position is inserted into the switching port, then a user holds the hand-held part to enable the hook-shaped part to be embedded between the two elliptic cylinders of the switching port, and then rotation operation is carried out to enable the hook-shaped part to be clamped in the gap between the cylinders. The temporary portion is used to fold the through tube into a square hole of the temporary portion before the second ink containing bag 93 is used, so that the ink can be prevented from flowing back instantly, thereby leaking ink and polluting the environment. Preferably, the through connection clamping position can be provided with a screw ring 8205 for increasing the friction between the through pipe and the through connection clamping position, so that the connection is firmer.

Fig. 14 shows a state where the first and second ink containing bags are connected, and at this time, the transfer clip is connected to the transfer port of the first ink containing bag and the ink outlet of the second ink containing bag, so that the ink in the second ink containing bag is transferred into the first ink containing bag, the first ink containing bag does not need to be replaced, the chip does not need to be taken out and mounted, the detachment and mounting of the ink containing bag are reduced, the wear of the chip is reduced, and the situation that the chip cannot be used due to failure caused by frequent detachment and mounting is avoided.

The ink supply apparatus will now be described in detail with continued reference to fig. 15-28.

Referring to fig. 15-28, the present embodiment provides an ink supply apparatus, which specifically includes an ink storage container 91, an ink adding container 92, and an ink adding tube 94. The ink tank 91 is provided with an ink supply port 911 and an ink receiving port 912, and the ink supply port 911 is used for communication with the printing apparatus. The ink adding container 92 is provided with an ink filling port 921, one end of the ink adding tube 94 is communicated with the ink filling port 921, and the other end of the ink adding tube 94 is used for communicating with the ink receiving port 912 after the ink in the ink storage container 91 is used up, so as to fill the ink in the ink storage container 91. After the ink is used up, the ink storage container 91 can be filled with the additional ink through the ink adding container 92 and the ink adding pipe 94, the ink storage container 91 does not need to be taken down from the printing equipment, and the mounting and dismounting times of the ink storage container 91 are reduced, so that the problem of printing equipment failure caused by frequent dismounting of the ink storage container 91 can be avoided, and the running stability of the printing equipment is improved.

In this embodiment, when there is ink in the ink tank 91, the ink supply tube 94 and the ink supply tank 92 are both in a standby state and are not connected to the ink tank 91. The ink supply tube 94 is not connected to the ink tank 91 until the ink in the ink tank 91 runs out, and supplies the ink. That is, the ink supply tube 94 is detachably connected to the ink storage container 91, for example, the ink supply tube 94 may be connected to the ink storage container 91 by snap-fitting, and the ink supply tube 94 may be connected to the ink storage container 91 by bolting, as long as it is ensured that the ink supply tube 94 communicates with the ink receiving port 912 when the ink supply tube 94 is connected to the ink storage container 91. Thus, the ink supply tube 94 and the ink receiving port 912 can be separated from each other after the ink supply is completed, and the operation of the ink tank 91 is not affected. Of course, no connection structure may be provided between the ink receiving port 912 and the ink supply tube 94, and the ink supply tube 94 may be held by an operator and inserted into the ink storage container 91 while being fixed during ink supply. Thus, the ink supply tube 94 and the ink receiving port 912 can be separated immediately after the ink supply is completed.

In addition, the ink adding tube 94 and the ink adding container 92 can be detachably connected, for example, the ink adding tube 94 and the ink adding container 92 can be connected in a clamping manner, and of course, the ink adding tube 94 and the ink adding container 92 can also be connected in a bolt connection manner, as long as the ink adding tube 94 and the ink adding container 92 are connected, and the ink adding tube 94 and the ink filling port 921 can be communicated. Thus, the ink supply tube 94 can be separated from the ink supply container 92 when ink supply is not performed.

Alternatively, the ink feed tube 94 and the ink feed container 92 may be a single piece, i.e., the ink feed tube 94 and the ink feed container 92 are not detachable, whereby the ink feed tube 94 and the ink feed container 92 as a whole are convenient to store.

The present embodiment preferably has the ink feed tube 94 detachably connected to both the ink feed container 92 and the ink storage container 91, thereby facilitating the production, installation, and use of the ink supply apparatus.

Fig. 16 and 17 show the external configuration of the ink tank 91 from two angles, respectively, and referring to fig. 16 and 17, the ink tank 91 has a rectangular parallelepiped bag-like configuration, but the ink tank 91 may have a regular three-dimensional shape such as a cylindrical shape or a conical shape, or another irregular three-dimensional shape, as long as the ink tank 91 can be mounted inside the printing apparatus. The ink tank 91 may be made of materials such as ethylene terephthalate, nylon, polyethylene, and the like. The ink tank 91 may be formed by laminating a plurality of materials, and for example, the outermost layer may be formed of nylon or ethylene terephthalate, and the inner layer may be formed of polyethylene. Furthermore, a metal material such as aluminum may be deposited on the inner surface, thereby providing the ink container with excellent strength and toughness.

Further, the ink storage container further includes: the first connection portion 913 may have the ink supply port 911 disposed thereon. In addition, the first connection portion 913 may further include a chip engaging portion 914 and a handle 915, and the first connection portion 913 is configured to connect to a second connection portion in the printing apparatus, so as to communicate the ink supply port 911 with an internal ink pipeline of the printing apparatus, so as to supply ink to the printing apparatus. The grip 915 is rotatably connected to the first connecting portion 913 through a rotating shaft, and thus, an operator can attach and detach the ink container 91 through the grip 915, facilitating the attachment and detachment of the ink container 91. The chip engagement portion 914 is used for mounting a continuous ink supply chip 9141, and fig. 20 shows an enlarged view of a partial area of the chip engagement portion 914, and as shown in fig. 20, the continuous ink supply chip 9141 has been mounted on the chip engagement portion 914.

As shown in fig. 21, a plurality of spacing ribs 916 with different lengths are further disposed on the back of the first connection portion 913, and are used to increase the strength of the first connection portion 913, so as to facilitate the installation and fixation of the first connection portion 913, and thus, a stable mechanical connection relationship and an electrical connection relationship can be established with the printing apparatus.

Fig. 18 shows the external configuration of the ink container 92, and referring to fig. 18, the ink container 92 has a rectangular parallelepiped bag-shaped configuration, but the ink container 92 may have a regular three-dimensional shape such as a cylindrical shape, a conical shape, or other irregular three-dimensional shapes. The ink supply container 92 may be made of a material substantially similar to that of the ink storage container 91, and the embodiment will not be described in detail.

When the ink supply device of this embodiment is used to supply ink, the ink supply tube 94 may be connected to the ink storage container 91, and then the other end of the ink supply tube 94 may be connected to the ink storage container 92, and the ink supply method may be manually squeezing to squeeze the ink into the ink storage container 91. In other possibilities, it is also possible to raise the ink reservoir 92 to allow the ink to flow into the reservoir 91 by gravity, or to vary the pressure difference between the reservoir 91 and the ink reservoir 92 by means of a pressure pump. In any manner, it is sufficient if the flow of the ink in the ink adding tank 92 to the ink tank 91 can be driven. Therefore, after the ink in the ink storage container 91 is used up, the ink can be replenished again through the ink adding container 92, so that the times of disassembling and assembling the ink storage container 91 are reduced, and the problem of printing equipment failure caused by frequent disassembling of the ink storage container 91 can be effectively solved.

Of course, the present embodiment is not limited to one ink supply tank 92 supplying ink to one ink storage tank 91. Optionally, the ink supply device may further include: a plurality of ink supply tubes 94 and a plurality of ink supply containers 92, each of the ink supply ports 921 being communicated with one of the ink supply containers 92 through one of the ink supply tubes 94. Thus, ink can be simultaneously filled into one ink tank 91 through a plurality of ink tanks 92. Of course, it is also possible to supply ink to a plurality of ink tanks 91 simultaneously through one ink supply container 92, and accordingly, it is necessary to connect a plurality of ink supply tubes 94 to the ink supply container 92, each ink supply tube 94 communicating with one ink tank 91, so that the ink supply container 92 can supply ink to a plurality of ink tanks 91 through the plurality of ink supply tubes 94.

Alternatively, the ink receiving port 912 and the ink injecting port 921 may have a regular shape such as a circle, a rectangle, an ellipse, or other irregular shapes. The present embodiment preferably provides the ink receiving port 912 and the ink injection port 921 in a substantially similar shape, for example, an oval shape, thereby facilitating connection with the ink supply tube 94.

Alternatively, the ink supply tube 94 is preferably a rubber hose for easy connection and installation, but the ink supply tube 94 may be a plastic tube, a glass tube, a steel tube, or the like.

The ink supply device provided in the present embodiment includes an ink tank 91, an ink supply tank 92, and an ink supply tube 94, and the ink tank 91 is used inside the printing apparatus to supply ink to the printing apparatus. When the ink in the ink storage container 91 is used up, one end of the ink adding pipe 94 is communicated with the ink receiving port 912 of the ink storage container 91, and the other end of the ink adding pipe 94 is communicated with the ink injecting port 921 of the ink adding container 92, so that the ink adding container 92 can convey the ink to the ink storage container 91 through the ink adding pipe 94, the ink storage container 91 does not need to be replaced, the dismounting and mounting times of the ink storage container 91 are reduced, the abrasion of a connecting structure matched with the ink storage container 91 in the printing equipment is avoided, and the problem of printing equipment failure caused by frequent dismounting is effectively solved.

Further, referring to fig. 16 and 22, the ink storage container 91 is provided with an adapter 917, the ink receiving port 912 is provided on the adapter 917, the connection port 912 is provided with a one-way flow device 918, and the one-way flow device 918 only allows ink to enter the ink storage container 91 from the ink receiving port 912. Therefore, the backflow of the ink in the ink storage container 91 from the ink receiving port 912 can be limited, and the environmental pollution and the ink loss caused by the ink flowing out are avoided.

As shown in fig. 16, the adaptor 917 is disposed at an end of the ink tank 91 opposite to the first connection 913, but of course, the adaptor 917 may be disposed at another position of the ink tank 91. The adaptor 917 may be integrated with the ink container 91, that is, both may be integrally formed, or may be a split structure, that is, after the ink container 91 and the adaptor 917 are respectively processed, the adaptor 917 is mounted on the ink container 91. It should be noted that the connection between the adaptor 917 and the ink container 91 needs to ensure good sealing, for example, the adaptor 917 may be partially inserted into the ink container 91 and the connection between the adaptor 917 and the ink container 91 may be sealed by welding. Thus, ink leakage from the joint can be prevented.

In the present embodiment, the adaptor 917 and the ink storage container 91 are preferably a split structure, thereby facilitating the processing and manufacturing of the ink storage container 91.

Fig. 23 further shows an external structural schematic diagram of the adaptor 917, and referring to fig. 22 and fig. 23, the adaptor 917 further includes: the cylindrical tube 9171, the sealing rib 9172, and the ink flow hole 9173, and the ink receiving port 912 are provided at one end of the cylindrical tube 9171, and it is understood that at least a part of the cylindrical tube 9171 is located in the ink storage container 91, thereby communicating the ink receiving port 912 and the ink storage container 91. Alternatively, the cylindrical tube 9171 may be a regular solid shape such as a cylinder, a cube, an elliptic cylinder, or other irregular solid shape.

The sealing ribs 9172 are provided on the outer periphery of the cylindrical tube 9171 and contact the outer wall of the ink storage container 91, the edges of the sealing ribs 9172 are smooth straight lines or curved lines, and the sealing ribs 9172 can be welded and sealed with the ink storage container 91, so that the sealing between the cylindrical tube 9171 and the ink storage container 91 is further enhanced by the sealing ribs 9172.

The ink flow holes 9173 are provided in a portion of the cylindrical tube 9171 located in the ink reservoir 91, and penetrate through the side wall of the cylindrical tube 9171 in a direction perpendicular to the center line of the cylindrical tube 9171, that is, the ink flow holes 9173 are provided in the side wall of the cylindrical tube 9171 located in the ink reservoir 91, so that ink can flow into the ink reservoir 91 through the ink flow holes 9173. That is, the one-way flow device 918 is used for controlling the opening and closing of the ink flow hole 9173, the ink adding tube 94 extends into the ink receiving port 912, and under the pressure of ink in the tube, the one-way flow device 918 is opened, so that the ink flows into the cylindrical tube 9171 from the ink adding tube 94 and continues to flow into the ink storage container 91 through the ink flow hole 9173, and the ink supplying process is completed. When the pressure of ink inside the ink feed tube 94 decreases, the one-way flow mechanism 918 closes again to close the ink flow hole 9173, so that ink cannot flow into the ink tank 91 and the ink supply mechanism stops supplying ink. Of course, controlling the opening and closing of the one-way flow device 918 by the pressure of the ink in the ink supply tube 94 is only one possible implementation of the ink supply device provided in this embodiment, and in other possible embodiments, the strength of the ink supply tube 94 itself may be used directly to open the one-way flow device 918, or the first joint 95 described below may be used to open the one-way flow device 918.

Alternatively, the ink flow apertures 9173 may be rectangular as shown in FIG. 23, or may be regular shapes such as circles, ovals, triangles, or other irregular shapes. The present embodiment preferably has two rectangular ink flow holes 9173 provided on the outer wall of the cylindrical tube 9171 inside the ink storage container 91, whereby the ink supply efficiency can be improved.

With continued reference to fig. 22, the one-way flow device 918 further includes a stop block 9181 and an elastic member 9182, a sealing flange 9183 is disposed in the ink receiving port 912, the stop block 9181 is disposed on a side of the sealing flange 9183 facing the inside of the ink storage container 91, and the elastic member 9182 is used for abutting against the stop block 9181 toward the sealing flange 9183, so that the stop block 9181 is in contact with the sealing flange 9183. When the stopper 9181 is in contact with the sealing flange 9183, the ink flow holes 9173 provided in the side wall of the cylindrical tube 9171 are shielded by the stopper 9181, thereby disconnecting the ink-receiving port 912 from the ink flow holes 9173. When the stopper 9181 is away from the sealing flange 9183, that is, in the state shown in fig. 22, the ink flow hole 9173 is no longer shielded, so that the ink receiving port 912 communicates with the ink flow hole 9173, and ink can enter the cylindrical tube 9171 from the ink receiving port 912 and flow into the ink storage container 91 from the ink flow hole 9173.

Of course, the one-way flow device 918 is not limited to the above structure, and may be other structures as long as it can ensure that the ink can flow in one direction, for example, the one-way flow device 918 may be an electromagnetic locking device, and the opening or closing of the ink receiving port 912 is controlled by power failure, so as to limit the flow direction of the ink.

Alternatively, the elastic member 9182 may be any member capable of generating an elastic force, such as a spring, a tension spring, a torsion spring, or the like, and preferably, the elastic member 9182 is a spring, more specifically, a compression spring.

Optionally, an elastic piece mounting groove 9184 may be further disposed on one side of the stopping block 9181, which is away from the sealing flange 9183, one end of the elastic piece may be mounted in the elastic piece mounting groove 9184, and the other end of the elastic piece may be mounted on a fixing plate located at the end of the cylindrical tube 9171, so that the elastic piece may be prevented from falling off when the stopping block 9181 moves repeatedly.

With continued reference to fig. 22, the stopper 9181 is formed of two cylindrical bodies, including a first cylindrical body 9181 ' having a larger diameter and a second cylindrical body 9181 "having a smaller diameter and projecting from the first cylindrical body 9181 ' toward the sealing flange 9183, wherein the outer diameter of the first cylindrical body 9181 ' is substantially the same as the inner diameter of the cylindrical tube 9171, so as to prevent ink from flowing through two gaps, i.e., ink can only flow through the ink flow holes 9173, thereby preventing ink from contaminating the elastic members 9182 after passing through the stopper 9181.

The sealing flange 9183 is of an annular configuration with a central opening formed at the center thereof, and when the unidirectional flow device 918 is closed, the second post 9181 ″ is inserted into the central opening with the outer wall thereof contacting the inner wall of the sealing flange 9183 to form a sealed state, whereby the unidirectional flow device 918 is closed. Further, when the second cylinder 9181 ″ is inserted into the center hole of the sealing flange 9183, the end surface of the first cylinder 9181' may abut with the end surface of the sealing flange 9183, so that another sealing structure may be formed, whereby the sealing effect of the unidirectional flow device 918 may be improved. Still further, the periphery of the end surface of the first cylinder 9181' facing the sealing flange 9183 is further provided with an annular protrusion 9185, and when the sealing flange 9183 is a rubber member, the annular protrusion 9185 deforms the sealing flange 9183 when contacting the sealing flange 9183, so that the sealing effect can be further improved.

When the one-way flow device 918 is activated, the second post 9181 "is forced outwardly away from the central bore of the sealing flange 9183, the end surface of the first post 9181' and the end surface distal from the sealing flange 9183, until the ink flow aperture 9173 is fully exposed, allowing ink to flow through the ink flow aperture 9173, whereby the one-way flow device 918 is fully activated.

Of course, the above structure of the stop block 9181 is only one possible implementation manner of the present embodiment, and in other possible designs, the stop block 9181 may also have a conical structure, a cubic structure, or the like.

With continued reference to fig. 22, the cylindrical tube 9171 has an annular groove 9186 inside the tube, the annular groove 9186 is used for mounting a sealing flange 9183, and the sealing flange 9183 may be rubber or a metal component. The present embodiment preferably uses rubber for the sealing flange 9183. The rubber deforms under the action of force, so that the contact area between the rubber and the stop block 9181 can be enlarged, and the sealing effect is further improved. Further, the bottom of the annular groove 9186 extends along the extension direction of the inner pipe of the cylindrical pipe 9171 to form a shape that the width of the groove bottom is larger than that of the groove body, that is, as seen from the cross-sectional view in fig. 22, the cross section of the groove is in a "T" shape, in a possible implementation, the cylindrical pipe 9171 can be formed by two pipes with different diameters, a first pipe body with a larger diameter is sleeved outside a second pipe body with a smaller diameter, an ink receiving port 912 is arranged on the first pipe body, a one-way flow device 918 is arranged in the second pipe body, and an annular groove 9186 is defined by the end surface of the second pipe body facing the ink receiving port 912 and the inner wall of the first pipe body, and can be used for installing the sealing flange 9183. Of course, in other possible embodiments, the cylindrical tube 9171 may be a unitary piece with the inner wall of its inner conduit recessed to form the annular recess 9186.

Correspondingly, the peripheral edge of the sealing flange 9183 also has an extension part extending along the extension direction of the cylindrical pipe 9171, so that the sealing flange 9183 can be clamped into the bottom of the groove, and the connection stability of the sealing flange 9183 and the annular groove 9186 is improved.

Further, as shown in fig. 24 to 26, the ink adding tube 94 communicates with the ink receiving port 912 through a first joint 95, the first joint 95 includes a first tube 951, one end of the first tube 951 communicates with the ink adding tube 94, and the other end of the first tube 951 is configured to be inserted into the ink receiving port 912; and the first tube 951 abuts the stop 9181 to disengage the stop 9181 from the sealing flange 9183. After the stopper 9181 is separated from the sealing flange 9183, the first tube 951 is communicated with the ink flowing hole 9173, so that ink can flow into the cylindrical tube 9171 from the first tube 951 and then flow into the ink storage container 91 from the ink flowing hole 9173, and ink supply is completed.

The first pipe 951 includes a connection pipe section 9511, the connection pipe section 9511 is used for communicating with the ink adding pipe 94, when the ink adding pipe 94 is a hose, the ink adding pipe 94 can be directly sleeved on the connection pipe section 9511, wherein, the outer diameter of the connection pipe section 9511 is larger than the inner diameter of the ink adding pipe 94, so that when the ink adding pipe 94 is sleeved on the connection pipe section 9511, a certain positive pressure is applied to the surface of the connection pipe section 9511 due to the inward contraction tendency, and a friction force is formed to strengthen the connection.

Of course, the present embodiment is not limited to the above connection manner, for example, when the ink adding pipe 94 is a steel pipe, an internal thread may be disposed on an inner wall of the steel pipe, an external thread may be disposed on an outer wall of the connection pipe segment 9511, and the ink adding pipe 94 and the connection pipe segment 9511 may be connected by a thread.

The first pipe 951 is preferably made of a rigid cylindrical pipe, and accordingly, the first joint 95 can also be made of a rigid material, so that the elastic force of the elastic member 9182 on the stop block 9181 can be resisted by the rigidity of the first joint 95 itself, so that the stop block 9181 is separated from the sealing flange 9183, and the one-way flow device 918 can be opened to realize normal ink supply.

With continued reference to fig. 26, further, a sealing ring 9512 is disposed on the first tube 951, the sealing ring 9512 is used for sealing a gap between the first tube 951 and the ink receiving port 912, and the sealing ring 9512 divides the first tube 951 into a first tube 9513 close to the ink storage container 91 and a second tube 9514 far from the ink storage container 91. The sealing ring 9512 can prevent ink from leaking through a gap between the first pipe body 951 and the columnar pipe 9171, and the ink leakage is avoided to pollute the environment.

The sealing ring 9512 may be a rubber ring that deforms by deforming contact to provide a good seal, although the sealing ring 9512 may also be a metal ring. Optionally, sealing ring 9512 can be a multichannel seal structure, for example, sealing ring 9512 can be formed by three sealing ring combinations, and adjacent sealing ring interval is certain distance to form groove structure, the inside ink that can be used to hold the leakage of recess, can strengthen sealed effect again after the recess is full of to the ink simultaneously, from this, can further improve sealing ring 9512's sealed effect.

In order to install the sealing ring 9512, a protrusion 9515 may be further disposed on the first pipe 951, as shown in fig. 25 and 26, a protrusion 9514 is disposed on the first pipe section 9513, an end surface of the protrusion 9515 facing the sealing ring 9512 is a plane perpendicular to a center line of the first pipe section 951, and a diameter of the second pipe section 9514 is larger than that of the first pipe section 9513, so that a mounting groove is defined by the end surface of the protrusion 9515 facing the sealing ring 9512, the end surface of the second pipe section 9514 facing the sealing ring 9512, and an outer wall of the first pipe section 9513, and the sealing ring 9512 is mounted in the annular groove, thereby effectively improving the mounting stability of the sealing ring 9512.

Further, the end surface of the protrusion 9515 facing away from the sealing ring 9512 may be provided as an inclined surface, and the sealing ring 9512 is sleeved on the first pipe segment 9513 by the end of the first pipe segment 951 and moves toward the second pipe segment 9514 to be installed in the installation groove. The slope of the sloped surfaces of the protrusions 9515 may follow the direction of movement of the seal ring 9512 on the first pipe segment 9513, thereby facilitating installation of the seal ring 9512.

Here, it should be noted that the "seal ring 9512 divides the first tube 951 into a first tube 9513 close to the ink tank 91 and a second tube 9514 far from the ink tank 91" is to give different names to different parts of one tube for convenience of the following description, rather than dividing the first tube 951 into two tubes which are completely independent or spaced apart, that is, the first tube 9513 and the second tube 9514 are still in communication and are one piece.

As shown in FIG. 25, the end of the first tube segment 9513 is provided with a notch 9516 extending perpendicular to the centerline of the first tube segment 9513. When the end of the first pipe segment 9513 abuts against the stop block 9181, the end surface of the first pipe segment 9513 contacts with the stop block 9181, so that the first pipe segment is closed by the stop block 9181, ink cannot smoothly flow out, and the ink can be ensured to flow out of the notch 9516 through the notch 9516 arranged at the end of the first pipe segment 9513, so that ink can be smoothly supplied to the ink storage container 91.

Optionally, the notch 9516 may be regular in shape, such as a circle, a rectangle, a triangle, or other irregular shape, and in this embodiment, the notch 9516 is preferably rectangular and arranged oppositely, that is, two rectangular notches 9516 are symmetrically arranged at the end of the first pipe segment 9513. Of course, more slits 9516 may be provided to further improve ink supply efficiency.

With continued reference to FIG. 25, the sidewall of the first pipe segment 9513 may also be provided with a through hole 9517. The through holes 9517 may be in a regular shape such as a circle, a rectangle, an ellipse, or other irregular shapes. This embodiment provides two symmetrical rectangular through holes in the first pipe section 9513, and thus, the ink supply efficiency can be improved by the through holes 9517. Of course, more through holes 9517 may be provided to further improve ink supply efficiency.

Preferably, the first pipe section 9513 is provided with a notch 9516 and a through hole 9517, so that the ink supply efficiency can be further improved.

Optionally, the second pipe segment 9514 is provided with a connection external thread (not shown in the figure), and the sidewall of the ink receiving port 912 is provided with a connection internal thread (not shown in the figure) matching with the connection external thread. Therefore, the first pipe 951 can be connected with the ink receiving port 912 through threads, the connection mode is simple, and the connection structure is reliable. In addition, the screw thread can play a sealing role, thereby preventing ink from leaking along the gap between the first tube 951 and the ink receiving port 912 and causing environmental pollution.

Optionally, the first joint 95 further includes a first clamping portion, the first clamping portion is disposed on the first pipe 951, the switching portion 917 is disposed on the second clamping portion, and the first clamping portion is clamped with the second clamping portion. Therefore, when supplying ink, the first joint 95 can be connected with the adapter 917 via the first and second clamping portions, and when not supplying ink, the first joint 95 can be detached.

The first clamping portion may be a clamping groove and the second clamping portion may be a clamping block, or the first clamping portion may be a clamping block and the second clamping portion may be a clamping groove. The clamping block is clamped in the clamping groove, so that the first clamping portion and the second clamping portion are clamped together.

second dogs

9523 and 9524 are sandwiched between the first and

second stops

9531 and 9532 after the first joint 95 is rotated. Thus, the first joint 95 and the adaptor 917 are easy to mount and dismount. Meanwhile, when the first fixture block 9523 and the second fixture block 9524 are located in the gap formed by the first baffle 9531 and the second baffle 9532, the first joint 95 cannot be further inserted into the ink receiving port 912 and cannot be withdrawn from the ink receiving port 912, so that the first joint 95 can be well positioned and fixed.

It is understood that only one first baffle 9531 may be provided to limit the first joint 95 from exiting the ink inlet 912.

The two notches are formed in the first baffle 9531 and are used for allowing the first claw 9521 and the second claw 9522 to penetrate through, after the two claws penetrate through the notches, the first fixture block 9523 and the second fixture block 9524 are located between the first baffle 9531 and the second baffle 9532, at this time, the first connector 95 is rotated to enable the first fixture block 9523 and the second fixture block 9524 to leave the positions close to the notches and cannot be withdrawn from the notches, and therefore the first connector 95 is clamped with the adaptor 917.

Alternatively, the first baffle 9531 and the second baffle 9532 can be rectangular, circular, oval, etc. regular shapes, or other irregular shapes.

In addition, optionally, in this embodiment, a mode of threaded connection and clamping connection can be set simultaneously, that is, a connection external thread is provided on the second pipe section 9514, a connection internal thread matched with the connection external thread is provided on the side wall of the ink receiving port 912, the first joint 95 can be connected with the adapter 917 through a thread, and meanwhile, the first joint 95 further includes a first clamping portion, and the adapter 917 further includes a second clamping portion. First joint portion 951 and second joint portion can adopt foretell joint mode, just that is to go into the joint mode in the draw-in groove through rotatory back card of first jack catch 9521 and second jack catch 9522. Therefore, by rotating the first joint 95, on one hand, threaded connection can be achieved, and on the other hand, clamping connection can be achieved, so that the connection strength between the first joint 95 and the adapter 917 can be further enhanced.

Alternatively, the ink adding tube 94 communicates with the ink adding container 92 through a second joint 96, and the second joint 96 is detachably connected to the ink adding container 92. Therefore, the ink supply device is convenient to mount and dismount.

The second joint 96 may be configured substantially similarly to the first joint 95, and accordingly, the ink injection port 921 may be configured substantially similarly to the ink receiving port 912 in order to be engaged with the second joint 96 to communicate the ink supply container 92 and the ink supply tube 94, thereby simplifying the manufacturing and production of the ink supply apparatus and improving the productivity.

Alternatively, the ink injection port 921 may be provided on an adapter, and a one-way flow device may be provided in the ink injection port 921, the one-way flow device allowing only ink to enter the ink supply tube 94 from the ink injection port 921. Therefore, the ink in the ink container 92 can be restricted from flowing out from the ink injection port 921, and environmental pollution can be avoided. The specific structure of the adapter section and the unidirectional flow device is substantially similar to the adapter section 917 and the unidirectional flow device 918, and the description thereof is omitted here.

Optionally, the second joint 96 may further include: and one end of the second pipe body is communicated with the ink adding pipe 94, the other end of the second pipe body is used for being inserted into the ink injection port 921, and the second pipe body abuts against the stop block of the one-way flow device so as to enable the stop block to be separated from the sealing flange.

Alternatively, a sealing ring may be disposed on the second tube for sealing a gap between the second tube and the ink injection port 921, and the sealing ring divides the second tube into a first tube section close to the ink container 2 and a second tube section far from the ink container 2.

Optionally, the end of the first tube section is provided with a notch extending perpendicular to the centre line of the first tube section, whereby ink in the ink container can flow into the second tube through the notch.

Optionally, a through hole may be further provided on the side wall of the first pipe section of the second pipe body, so that the ink in the ink adding container can flow into the second pipe body through the through hole, thereby further enhancing the ink supply efficiency.

Alternatively, a connecting external thread is provided on the second pipe section of the second pipe body, and a connecting internal thread matched with the connecting external thread is provided on the side wall of the ink injection port 921, so that the second joint 96 and the ink injection port 921 can be connected by a thread.

Thus, the second joint 96 and the ink supply port 921 can be connected by snap-fit.

In this embodiment, the ink adding tube 94 is preferably a flexible tube, the first joint 95 further includes a handheld portion 954 disposed on the first tube 951, the handheld portion 954 is provided with a hole 9541, and the hole 9541 is used for storing the folded ink adding tube 94.

As shown in fig. 25, the handle 954 of the first joint 95 has a rectangular plate-like structure, so that the operator can rotate the first joint 95 to clamp the first claw 9521 and the second claw 9522 into the gap between the first baffle 9531 and the second baffle 9532. Of course, the handle 954 may take other forms so long as it is easily held by a human hand. For example, it may be a handle disposed on the first tube 951.

The term "the process hole 9541 is used for storing the folded ink supply tube 94" means that after the ink supply tube 94 is folded or bent, the bent portion is deformed and closed, and thus, the folded or bent ink supply tube 94 is stored in the process hole 9541 in a folded or bent state, because the ink supply tube 94 has a tendency of recovering to the original state, the tendency is restricted by the process hole 9541, so that a certain positive pressure is applied to the hole wall of the process hole 9541 by the ink supply tube 94, and the positive pressure is converted into a friction force, thereby ensuring that the folded or bent ink supply tube 94 can be placed in the process hole 9541 without falling. Therefore, the ink can be prevented from flowing back instantly when the first connector 95 is inserted into the ink receiving port 912, thereby preventing ink leakage and environmental pollution.

Optionally, the second connector 96 may also include a handheld portion disposed on the second tube, and a process hole may also be disposed on the handheld portion, and the specific structure of the second connector is substantially similar to the handheld portion 954 and the process hole 9541 on the first tube 951, which is not described in detail herein.

In using the ink supply apparatus provided in this embodiment, first, one end of the ink supply tube 94 is connected to the first joint through the connection tube section 9511 of the first joint 95.

At the same time as the snap-fit is completed, as shown in fig. 26, the first tube end 9153 of the first connector 95 abuts against an end surface of the stop 9181 of the one-way flow device 918, and the stop 9181 moves away from the sealing flange 9183 under the urging force of the first tube segment 9153, thereby exposing the ink flow aperture 9173 and allowing the one-way flow device 918 to open. The other end of the ink supply tube 94 is connected to a second connector 96 via a connecting tube section of the second connector 96. Then, the second joint is inserted into the ink injection port 921, the one-way flow device located in the ink injection port 921 is gradually opened along with the extension of the second joint, and the second joint is then connected with the ink injection port 921 in a clamping manner, so that the two ends of the ink adding tube 94 are respectively communicated with the ink storage container 91 and the ink adding container 92, and the installation of the ink supply device is completed.
