The ink supply device 2 further includes a movable member 24 and an elastic member 25. The movable element 24 is movably sleeved on the periphery of the ink supply needle 23, and the elastic element 25 is connected between the movable element 24 and the shell 21; under the action of an external force, the movable member 24 can move relative to the ink supply needle 23 in the mounting direction or the direction opposite to the mounting direction, that is, the movable member 24 can move relative to the ink supply needle 23 in a direction approaching or departing from the housing 21 toward the inner wall of the ink cartridge 1, so that the movable member 24 has a first position and a second position.

Specifically, an ink channel 231 is provided through the ink supply needle 23, and an ink supply port 232 communicating with the ink channel 231 is provided at an end of the ink supply needle 23 facing the ink cartridge 1. The movable element 24 has a mounting channel 246 extending therethrough, and the end of the movable element 24 facing the ink cartridge 1 has an elastic opening 241 with a variable open/close state, and the ink supply needle 23 is inserted into the mounting channel 246.

In the initial state (when the ink cartridge 1 is not installed), the movable member 24 is in the first position, in which the elastic opening 241 is in the closed state, the ink supply needle 23 is located in the installation channel 246, that is, the ink supply port 232 is located in the installation channel 246, and the ink supply port 232 is located at a certain distance from the elastic opening 241.

When the ink cartridge 1 is installed in the accommodating chamber 22 of the ink supply device 2 along the installation direction, the movable member 24 is located at the second position, at this time, the elastic opening 241 is in contact with the ink supply needle 23 and is in an open state, and at least a portion of the ink supply needle 23 extends out of the installation channel 246 from the elastic opening 241, that is, the ink cartridge 1 pushes against the movable member 24 to move the movable member 24 relative to the ink supply needle 23 along the installation direction, so that the ink supply needle 23 pierces the elastic opening 241 to extend out of the installation channel 246 and is inserted into the ink outlet 12 of the ink cartridge 1. The ink in the liquid storage cavity can be supplied to a jet printing device (such as a printing head) in the electronic equipment through the ink outlet 12, the ink supply port 232 and the ink channel 231.

When the ink cartridge 1 is removed from the accommodating chamber 22 of the ink supply device 2 in the opposite direction of the mounting direction, the movable member 24 is in the third position, at this time, the movable member 24 moves in the opposite direction of the mounting direction relative to the ink supply needle 23 under the elastic action of the elastic member 25, so that the ink supply needle 23 extends into the mounting channel 246 from the elastic opening 241, the elastic opening 241 is closed under the self-elastic action, the contact between the ink supply needle 23 and the outside air is blocked, the problems that foreign matters in the air enter the ink supply needle 23 and the ink remaining in the ink supply needle 23 is condensed after being dried in the air to block the ink supply needle 23 are avoided, and the use satisfaction degree of the electronic imaging device 100 is improved.

In the process of the return movement of the movable element 24, a certain friction force exists between the movable element 24 and the ink supply needle 23, the elastic element 25 continuously releases elastic potential energy, so that the elastic force applied to the movable element 24 by the elastic element 25 is continuously reduced, when the elastic force is equal to the friction force, the movable element 24 does not move any more and is in a static state, and the distance of the return movement of the movable element 24 is smaller than the distance of the movement of the ink cartridge 1 pushing the movable element 24, namely, the first position and the third position are not coincident.

In the initial state (the movable element 24 is in the first position), if the distance between the ink supply port 232 and the elastic opening 241 is small or exactly coincides, the friction force exists between the movable element 24 and the ink supply needle 23, which may cause the ink supply needle 23 not to completely extend into the installation channel 246, that is, the ink supply port 232 is still located outside the installation channel 246, so that it is impossible to prevent the foreign matters in the air from entering the ink supply needle 23 and the residual ink in the ink supply needle 23 from being coagulated after being dried to block the ink supply needle. Therefore, when the movable member 24 is at the first position, the ink supply needle 23 is spaced from the elastic opening 241 by a certain buffering distance, and when the ink cartridge 1 pushes the movable member 24 to move, the elastic member 25 can store more elastic potential energy, thereby avoiding the problem that the ink supply needle 23 cannot fully extend into the installation channel 246.

Referring to fig. 7 to 9, in some embodiments, the movable element 24 includes a body portion 242 and a buffering portion 243, the mounting channel 246 is disposed through the body portion 242 and the buffering portion 243, the buffering portion 243 extends from an end of the body portion 242 facing the ink cartridge 1 in a direction opposite to the mounting direction, and an outer diameter of the buffering portion 243 is greater than an outer diameter of the body portion 242. The elastic member 25 includes a first connection end 251 and a second connection end 252, the first connection end 251 is connected to or abutted against the housing 21, and the second connection end 252 is sleeved on the outer circumference of the main body 242 and connected to or abutted against the end of the buffer portion 243 away from the ink cartridge 1.

Specifically, the elastic element 25 is sleeved on the outer periphery of the ink supply needle 23 and the main body 242, the first connection end 251 can be connected to the inner wall of the housing 21 facing the ink cartridge 1 by snap fitting, welding, adhering, integral molding, or the like, and the first connection end 251 can also be directly abutted against the inner wall of the housing 21 facing the ink cartridge 1 without being connected to the housing 21; similarly, the second connecting end 252 may be connected to the end of the buffering portion 243 away from the ink cartridge 1 by snap fitting, welding, adhesion, integral molding, or the like, and the second connecting end 252 may also be directly abutted against the end of the buffering portion 243 away from the ink cartridge 1 without being connected to the buffering portion 243, and in addition, the second connecting end 252 may also be disposed in the installation channel 246 of the movable element 24, that is, as long as the elastic element 25 can be stably connected to the movable element 24. In the initial state, that is, when the movable element 24 is at the first position, the ink supply needle 23 is located in the main body 242, the width of the buffering portion 243 in the installation direction is a buffering distance between the ink supply port 232 and the elastic opening 241, and the width of the buffering portion 243 in the installation direction can be set according to actual requirements, which is not specifically described herein.

In one possible embodiment, the movable member 24 further includes a sealing portion 244, and the sealing portion 244 extends from an end of the buffer portion 243 facing the ink cartridge 1 in a direction opposite to the mounting direction. The elastic opening 241 is provided at an end of the sealing portion 244 facing the ink cartridge 1, and at least a part of the sealing portion 244 is insertable into the ink outlet 12 provided on the ink cartridge 1.

In the embodiment of the present application, the sealing portion 244 has a hemisphere shape, and the sealing portion 244 has a hollow structure inside.

Referring to fig. 10 and 11, in the initial state, the ink supply needle 23 extends into the installation channel 246, that is, the distance between the ink supply port 232 and the inner wall of the housing 21 facing the ink cartridge 1 is smaller than the distance between the elastic opening 241 and the inner wall of the housing 21 facing the ink cartridge 1, at this time, the elastic opening 241 is in the closed state, and the movable member 24 can play a role of sealing the ink supply needle 23, so as to prevent the foreign matters in the air from entering the ink channel 231 from the ink supply port 232 to block the ink supply needle 23.

Referring to fig. 12 and 13, when the ink cartridge 1 is installed in the ink supply device 2, the first sidewall 111 abuts against the end of the buffer portion 243 facing the ink cartridge 1, the ink cartridge 1 pushes the movable member 24 to move relative to the ink supply needle 23 along the installation direction (the direction close to the inner wall of the housing 21 facing the ink cartridge 1), at this time, the ink supply needle 23 can pierce the elastic opening 241 and extend out of the installation channel 246, that is, the distance between the ink supply opening 232 and the inner wall of the housing 21 facing the ink cartridge 1 is greater than the distance between the elastic opening 241 and the inner wall of the housing 21 facing the ink cartridge 1, and at least a portion of the sealing portion 244 can be inserted into the ink outlet 12 to prevent the ink in the liquid storage chamber from leaking out from the gap between the movable member 24 and the ink outlet 12. The end of the buffer portion 243 remote from the ink cartridge 1 may abut against the inner wall of the case 21 facing the ink cartridge 1, and may serve to limit the insertion depth of the ink cartridge 1.

With continued reference to fig. 10 and 11, when the ink cartridge 1 is removed from the ink supply device 2, the elastic member 25 releases elastic potential energy, the movable member 24 moves in the opposite direction of the mounting direction (the direction away from the housing 21 toward the inner wall of the ink cartridge 1) relative to the ink supply needle 23 under the elastic action of the elastic member 25, at this time, the ink supply needle 23 extends into the mounting channel 246 from the elastic opening 241, that is, the distance between the ink supply port 232 and the inner wall of the housing 21 facing the ink cartridge 1 is smaller than the distance between the elastic opening 241 and the inner wall of the housing 21 facing the ink cartridge 1, and the elastic opening 241 returns to the closed state under the self-elastic action, thereby playing a role of sealing the ink supply needle 23, preventing foreign matters in air from entering the ink channel 231 from the ink supply port 232 and preventing residual ink in the ink channel 231 from being air-dried and coagulated to block the ink supply needle 23.

Referring to fig. 14, in another possible embodiment, an elastic opening 241 is provided at an end of the buffer portion 243 facing the ink cartridge 1. This simplifies the construction of the movable member 24 and reduces costs.
