Description

Toothbrush with toothpaste

The present invention is a toothbrush toothpaste embedded toothpaste, more specifically, the toothpaste is embedded in the body unit to maximize the portability of the toothbrush, but the toothpaste is hardened at the nozzle area through which the toothpaste is discharged from the brush head through the discharge module installed in the bristles The present invention relates to a toothpaste-type toothbrush that can be conveniently solved and at the same time provides toothpaste with ease and easily removes moisture while enhancing the durability of the body.

Toothbrushes require the use of toothpaste. Toothbrush and toothpaste are separated, which prevents usability problems. At the same time, the toothbrush is squeezed to remove the inconvenience of having to be buried in the bristles of the toothbrush. In order to ensure the portability of the toothpaste toothbrushes are built in a variety of structures and types are being studied.

Looking at the prior art, most toothpaste-type toothbrushes receive toothpaste in the toothbrush body and then take a separate opening in the bristles along the outlet extending from the toothbrush body to the bristles of the toothbrush head to allow the toothpaste to flow to the bristles. It is taking structure.

In the state having such a structure, it is made to move the toothpaste in the bristle direction by turning the lever formed in the toothbrush body for the easy extraction of the toothpaste by the piston extrusion method or the pressing method of pressing the toothbrush body.

The present applicant has also applied for the Korean Utility Model Registration No. 442442, 'Toothbrush with toothpaste', and this technology is formed on the toothpaste body and presses the toothpaste by pressing the toothpaste by lever rotation. It is characterized by having a toothbrush with which the toothpaste embedded in the toothbrush body more easily withdrawn.

However, when the state stored in the toothbrush body is continued due to the nature of the toothpaste, the toothpaste becomes hard and does not leak out smoothly. In the case of toothpaste embedded in the toothbrush body, the solid state can be easily released by pressing. Although it is possible to solidify at the nozzle of the bristle part, it was difficult to provide a method for smoothly treating it.

Therefore, in order to prevent the solidification of the toothpaste, Korean Utility Model Registration No. 400905 'Toothpaste hardening prevention lid and toothpaste tube cover of toothpaste withdrawal toothbrush, the toothpaste solidified by the lid to be mounted around the bristles operating in the hinge type However, in order to remove the solidified toothpaste, the inconvenience of using the cap to be attached to the area around the bristles, and to prevent the hardening of the toothpaste by using the toothpaste in the liquid form, such as Korean Utility Model Registration No. 247899 Although there are many types of liquid toothpaste and the price is expensive, there is an economic disadvantage that is not selected by consumers.

As another method for preventing the problem of hardening of the toothpaste, there is a technology that can minimize the problem of hardening of the toothpaste by incorporating a motor in the toothbrush body to stir the toothpaste or to install a pump to induce quantitative discharge of the toothpaste In this case, however, the toothbrush manufacturing cost is significantly increased due to the structural complexity of installing a motor or a pump in the toothpaste-containing toothbrush, which may result in a consumer's external appearance.

Therefore, it is necessary to present a toothpaste-type toothbrush that can prevent an improved toothpaste hardening problem that does not present a complicated structure of the toothbrush body while providing a convenient operation method.

In addition, the toothpaste is drawn out by the piston compression method, but the smooth air flow structure and the stable mechanical structure are presented to increase the compression efficiency of the piston, and when the water penetrates into the toothbrush body during the brushing process, it is efficiently discharged. In addition to minimizing the problem of toothpaste deformation, there is a need to develop new and advanced toothpaste embedded toothbrushes that allow for the structural stability of the toothbrush body.

The present invention has been made in order to overcome the problems of the above technology, to provide a toothbrush with a toothpaste, as the toothpaste is drawn out by a piston extrusion method and at the same time the toothpaste is discharged from the nozzle formed protruding to a height similar to the bristles The toothpaste does not stick to the lower part of the bristles, which not only reduces the problem of bristles being contaminated by the hardened toothpaste, but also allows the nozzle and bristles to be easily separated from the head to ensure convenient cleaning, especially around the bristles. The main object of the present invention is to provide a toothpaste-type toothbrush which can easily remove and prevent the toothpaste that is cured.

Another object of the present invention is to provide a coupling structure in which the nozzle exposed to the outside is not easily released to the outside.

Still another object of the present invention is to provide a cleaning stick that can conveniently clean a part such as a nozzle in a state of convenience of storage.

It is a further object of the present invention to form a piston head in close contact with the toothpaste to extrude the toothpaste in a double structure to simultaneously provide a firmness to ensure a sufficient extrusion force while at the same time extruded cleanly to leave no residual toothpaste.

1 is a perspective view showing a schematic structure of the toothbrush embedded in the toothpaste of the present invention.

As can be seen from Figure 1, the toothbrush of the present invention has a shape such as a fountain pen or ballpoint pen to increase the convenience of carrying and to secure the convenience of storage by hanging in the pocket through the pocket hook portion 21.

In addition, the gauge 201 of the first body 200, that is, through the gauge made of a transparent window to expose the remaining amount of the toothpaste stored therein to the outside so that it is easy to check whether the toothpaste is charged.

Although not shown in the drawings, the toothbrush of the present invention may further include a play time notification module.

In other words, the play time notification module plays a role of informing the user when the play time, that is, the time when brushing is about a predetermined time (about 3 minutes), is usually about 3 minutes to guarantee the recommended brushing. do.

The play time notification module is composed of a timer and a notification unit. The timer provides a function of checking a preset time after starting brushing. At this time, whether or not brushing is started can be automatically determined through an additionally equipped motion sensor (acceleration sensor, gyroscope, etc.). In other words, the motion sensor recognizes a movement (which is repeated up and down) that can be recognized as performing brushing, and if there is a movement, time timing is started through a timer.

The notification unit performs a function of notifying the user when the preset time is reached. The notification unit is mounted on a specific portion of the first body 200 or the toothbrush and outputs a notification sound through a speaker and a light source output through an LED lamp. Can be.

Furthermore, the notification unit consists of a heating wire and a heat transfer unit on one side of the toothbrush gripping portion of the first body 200 to the user to generate a slight heat through the heating wire to transmit the mild heat to the user's hand to the heat transfer unit to inform the play time Can be provided.

Figure 2 is a perspective view showing the assembly structure of the head unit and the body unit to remove the cover from the toothbrush embedded toothpaste according to the present invention, Figure 3 is an exploded view showing a representative detailed configuration of the toothpaste built-in toothbrush according to the present invention Perspective view.

2, more specifically as shown in Figure 3, the toothbrush embedded toothpaste according to the present invention is detachably coupled to the first body 200, the cover 20, the bristles to cover the head unit 100 The head 110 and the gripping portion 120 and the head unit 100 having a thread 130 is formed, the first body 200 to provide a space for the toothpaste, and the piston rod assembly 300 It is composed of a second body 400 for pressing the toothpaste of the first body 200 in the bristle direction by the piston extrusion method, as a whole has a familiar appearance shape, such as a fountain pen, ballpoint pen.

As mentioned above, the cover 20 is detachably coupled to the first body 200 in order to prevent a problem in which the bristles are contaminated by exposing the head unit 100 to the outside. As can be seen, a plurality of ventilation openings 22 formed at a plurality of intervals with the pocket hook portion 21 formed in the longitudinal direction on the outer side at a predetermined interval, and the first body 200 around the inner side of the coupling end on the first body side ) Is provided with a locking guide (23) formed to achieve a firm coupling relationship.

Pocket hook portion 21 provides a function to ensure portability by conveniently hanging in the pocket or pocket of the user's top in the unused state of the toothbrush according to the present invention.

In addition, the vent 22 prevents contamination of the head unit 100 by sealing the cover 20, and ensures ventilation of the head unit 100 by allowing external air to flow therein, and at the same time, brushing. Not only plays a role of outflowing the residual moisture accumulated in the bristles to the outside in the process, serves to provide a space for storing the cleaning stick 50 to be described later.

The locking guide 23 is formed on the lower side of the cover 20, that is, inside the coupling end to the first body, and is formed to protrude from the guide groove 24 at the end of the guide groove 24 having a predetermined length embedded along the inner circumference. The protrusion 25 is provided.

According to the locking guide 23, the locking portion 230 of the first body 200 to be described later enters the guide groove 24, and then the locking portion 230 guides when the user rotates the cover 20. As the first body 200 and the cover 20 are coupled together by the stop protrusion 25 and the movement stops while the cover 20 is moved along the groove 24, the cover 20 is pulled by the first body. The cover 20 must be rotated and pulled to be separated without being separated from the 200 so as to prevent the cover 20 from being easily detached from the first body 200 to be lost.

Head unit 100 according to the present invention is detachably coupled to the front end (thread-mounted portion) of the first body 200 to have the same appearance as a toothbrush head in a general toothbrush, in detail the head 110, The gripper 120 and the thread forming portion 130 is made up.

Referring to FIG. 4, it can be seen that the head 110 is composed of a head housing, a discharge module 140, a nozzle 150, and bristles.

The head housing has a discharge module accommodating groove 111 for accommodating the discharge module 140 in which bristles are planted, and although not shown in the drawing, extends through the inner side along the longitudinal direction to receive toothpaste from the first body 200. It is provided with a passageway to be moved to.

A base accommodating groove 112 is formed in the center portion of the discharge module accommodating groove 111 to allow the base 151 of the nozzle 150 to be described later to be seated, and the base accommodating groove 112 is formed. At the central portion of the) is formed an outlet hole 113 for discharging the toothpaste moved along the passage to the outside.

The discharge module 140 is detachably accommodated in the discharge module accommodation groove 111 of the head housing, and the nozzle (3) is formed in a substantially center portion in a state where the bristle accommodation groove 141 is formed in a plurality of pieces so that the bristles are planted. The discharge portion 152 of the 150 is inserted to form a through hole 142 through which the toothpaste is supplied to the bristles, and on the opposite surface (back side) of the bristle receiving groove 141, the outer periphery of the periphery of the through hole 142 is formed. A plurality of fine protrusions 143 are formed along the protrusion.

The nozzle 150 is inserted into the through hole 142 of the discharge module 140 and protrudes in the bristle direction for a predetermined length by the length of the bristles, and the discharge part 152 of the flexible silicon material, and the through hole of the discharge module 140 ( In order to provide a stopper function that prevents the nozzle 150 coming out through the 142 from being moved outward, that is, the bristle direction, the base 151 is formed to have a predetermined diameter at the lower end of the discharge part 152.

Referring to the operation of the head 110 by this configuration, the toothpaste moved along the passage from the first body 200 is leaked to the outlet hole 113, the base receiving groove which is the portion around the outlet hole 113 Since the base 151 of the nozzle 150 is tightly accommodated in the 112, the tooth guide is naturally guided to the discharge part 152 leading to the top of the base 151 without fear of toothpaste leaking around the base receiving groove 112. .

Since the discharge part 152 is formed to protrude by a height similar to or slightly lower than the bristles to supply toothpaste to the upper part of the bristles, the toothpaste supply hole is more than a known discharge method in which toothpaste is supplied to the bristles at the bottom of the bristles. The toothpaste hardening can be remarkably reduced, and at the same time, ease of cleaning can be pursued.

If the discharge part 152 is blocked by the hardening of the toothpaste, the toothpaste hardening, which is difficult to solve especially around the bristles by inserting the cleaning stick 50 shown in FIG. 1 into the discharge part 152 to the outlet hole 113, may be difficult. Problems can be solved more easily.

The cleaning stick 50 has an end having a smaller diameter than the discharge part 152 and has a handle at the bottom of the end to give a smooth grip to the user, and the cleaning stick 50 has a cover 100. To be stored in the space in the cover 20 when covering the head unit 100 to prevent the problem to be lost in advance.

In addition, since the base-shaped base 151 formed at the lower end of the nozzle 150 is tightly accommodated in the base accommodating groove 112, it is possible to prevent a phenomenon in which toothpaste leaks to an unnecessary peripheral part, and Since the diameter is larger than the diameter of the discharge part 152 and the base 151 is located at the lower end of the discharge module 140, the nozzle 150 is easily separated from the through-hole 142 of the discharge module 140. Can be prevented appropriately.

In addition, a fine protrusion 143 is formed on the rear surface (back side) of the discharge module 140, that is, the periphery of the through hole 142 to which the base 151 is in close contact, and thus the periphery of the base 151 and the through hole 142. Since a certain friction acts, the nozzle 150 slides through the through hole 142 to block the phenomenon of slipping while sliding in the bristle forming direction.

The grip portion 120 is formed on the lower portion of the head 110 to facilitate the grip of the user, but in order to provide a more stable grip feeling, as shown in FIG.

A thread forming portion 130 is formed at a lower portion of the grip portion 120, and the thread forming portion 130 is threaded to the thread 220 of the first body 200. That is, the head unit 100 according to the present invention is detachable from the first body 200, and when the toothpaste is to be filled in the first body 200 using the toothpaste, the head unit 100 is first. After separating from the body 200, the toothpaste may be filled into a space in the first body 200, that is, the toothpaste storage unit 210.

Figure 5 is a perspective view showing a portion of the piston head and the piston rod in the coupled state of the first body and the second body, Figure 6 is a perspective view showing the appearance of the first body according to the present invention and the locking jaw and the stopper receiving groove Bottom view showing the structure.

The first body 200 according to the present invention has a transparent state and has a toothpaste storage unit 210 that can easily identify the remaining amount of toothpaste from the outside. The toothpaste storage unit 210 is a space in which the stored toothpaste is compressed while the toothpaste storage unit 210 is compressed. As the piston head 250 is positioned in the toothpaste storage unit 210, the piston rod 310 is slidably moved. .

The first body 200 is located between the head unit 100 and the second body 400, and the thread at the fastening end on the side of the first body 200 to be detachably threaded to the head unit 100 ( And a locking portion 230 protruding a predetermined height from the screw thread 220 in order to be fastened to the locking guide 23 of the cover 20 at one side of the thread 220 forming portion. Formed.

The lower portion of the first body 200, that is, the coupling end with the second body 400 has a larger diameter than the other portion (toothpaste storage portion) to provide a portion where the step occurs, the coupling jaw 231 The guide head 330 of the guide 320 of the piston rod assembly 300 is tightly inserted into the coupling jaw 231, and the guide head 330 is coupled to the first body 200. In order to prevent rotation in the state, the stopper receiving groove 240 which can accommodate the stopper 333 protruding from the upper surface of the guide head 330 may be coupled to the boundary between the jaw 231 and the toothpaste reservoir 210. Form on the inner wall. The stopper receiving groove 240 is recessed toward the toothpaste storage part 210 in the coupling jaw 231 having a diameter larger than the diameter of the toothpaste storage part 210. In other words, the stopper receiving groove 240 is formed. The formed portion means that the diameter of the toothpaste storage portion 210 and the diameter of the coupling jaw 231 is made identical.

Piston head 250 is located in close contact with the inner wall of the toothpaste storage unit 210.

That is, the piston head 250 has the same diameter as the inner diameter of the toothpaste storage unit 210, while pressing the toothpaste by the impact of the piston rod 310 in close contact with the inner diameter of the toothpaste storage unit 210 to move in the longitudinal direction In order to more smoothly squeeze the toothpaste structure, that is, the packing 260 located on the toothpaste storage unit 210 side and the supporter 270 located on the piston rod 310 side is composed of a combined state.

The packing 260 is provided with a protrusion 261 coupled to the supporter 270 on the bottom of a disc-shaped body made of a flexible silicone material, and has a larger diameter than the coupling protrusion 261 at the end of the coupling protrusion 261. A coupling end 262 is formed. In addition, the coupling protrusion 261 is tapered so that the diameter becomes narrower toward the end along the longitudinal direction.

The supporter 270 is made of plastic, which is harder than the packing 260, and a coupling groove 271 is formed at the center to accommodate the coupling protrusion 261 of the packing 260. 271 is formed with a tapered middle taper portion 272 so that the diameter becomes narrower from the upper and lower sides toward the center height point. In particular, the diameter of the packing 260 is slightly larger than the supporter 270, so that the packing 260 is in close contact with the inner wall of the toothpaste storage 210 in a slightly contracted state.

According to the piston head 250 having such a structure, it is made of a double coupling structure by the packing 260 and the supporter 270 is to complement each other.

Specifically, the packing 260 is slightly larger than the inner diameter of the toothpaste storage unit 210, but is made of a flexible material, so that it is in close contact with the inner wall of the toothpaste storage unit 210 while exhibiting elasticity. The toothpaste is compressed to prevent the toothpaste from leaking between the outer circumferential surface of the compression head 311 of the piston head 310 and the inner wall of the toothpaste reservoir 210 and at the same time, the inner wall of the toothpaste reservoir 210 is not contaminated. It performs a function to be able to cleanly flow into the passage of the head unit 100 without.

In addition, the supporter 270 is made of a rigid material to support the packing 260 from the bottom to prevent the problem that the packing 260 is made of a flexible material to prevent the packing itself does not provide a strong compression force to compress the toothpaste It serves to provide the overall propulsion force transmitted from the piston head 310.

At this time, the packing 260 and the supporter 270 are made of different materials, so when the adhesive method by the adhesive is applied, the bonding protrusions 261 and the coupling groove ( 271) provides a coupling method.

In particular, the width of the coupling protrusion 261 of the packing 260 becomes narrower (it looks like an inverted trapezoidal shape when viewed from the front side), and the coupling groove 271 of the supporter 270 is upwardly corresponding to this shape. It has a middle tapered portion 272 formed to have a smaller diameter toward the center portion and a larger diameter from the center portion to a lower portion, and acts in the vertical direction as in the engaging protrusion 261 having the same diameter. The coupling protrusion 261 may be closely coupled to the coupling groove 271 of the supporter 270 in a state of minimizing the possibility of slipping away from the coupling groove by external force. In addition, after providing the coupling end 262 which processed the diameter of the end of the coupling protrusion 261 large (that is, the diameter larger than the coupling groove), and after both are combined by the engaging action of this coupling end 262, Minimize the risk of deviation by external force.

Here, when the coupling end 262 is coupled to the coupling groove 271, although the diameter of the coupling end 262 is larger than the diameter of the coupling groove 271, the coupling protrusion 261 of the packing 260 is also made of silicone material. Since the coupling end 262 is forcibly pressed, the coupling protrusion 261 can be inserted into the coupling groove 271.

8 is a perspective view illustrating a coupling relationship between a piston rod assembly and a second body according to the present invention, and FIG. 9 is a perspective bottom view illustrating a coupling structure of the piston rod assembly and the second body according to the present invention.

The piston assembly 300 according to the present invention slides the piston rod 310 into the space in the toothpaste storage portion 210 of the first body 200 by the rotation of the rotation lever 410 installed in the second body 400. To perform the function of providing a compressive force to the piston head 250 to be moved, it consists of a piston rod 310 and the guide 320 large.

The piston rod 310 includes a crimping head 311 that is in close contact with the piston head 250 (more precisely, a supporter) and provides a crimping force, and a rod 312 that extends vertically in the crimping head 311. The rod 312 has a substantially rectangular parallelepiped shape, and threads 313 are formed on two surfaces facing each other, but a thread is not formed at a predetermined end portion of the rod 312.

The guide 320 has a shape that surrounds most of the piston rod 310 by receiving the piston rod 310 inside, and includes a guide head 330 surrounding a portion of the crimping head 311, and a rod. The guide rod 340 having a shape similar to the letter 'c' is wrapped around the bottom surface of the rod 313 and the two surfaces on which the thread 313 is not formed.

The guide head 330 has a predetermined length, ie, a crimping head accommodating groove 331 indented to correspond to a height of the crimping head 311 in an inward direction from an upper surface thereof, and a central portion of the crimping head accommodating groove 331. Has a rod receiving hole 332 formed in a shape corresponding to the rod 312 of the piston rod 310 (ie, a rectangular shape), and a stopper 333 is formed on the upper surface of the guide head 330. The air flow section 334 is recessed in the side wall of the guide head 330.

The guide head 330 is inserted and fixed to the first body 200. As described above, the guide head 330 is inserted into the coupling jaw 231 of the first body 200, and then the stopper 333 Is inserted into the stopper accommodating groove 240, the guide head 330 is fixedly coupled in a state of losing the rotation in the first body (200).

In this case, the diameter of the coupling jaw 231 and the diameter of the guide head 330 are the same, and both of them do not have elasticity, so that the guide head 330 cannot be smoothly inserted into the coupling jaw 231. In order to prevent this, the air distribution part is formed when the guide head 330 is inserted into the coupling jaw 231 by forming one or more air distribution parts 334 in the sidewall of the guide head 330. The guide head 330 is inserted into the coupling jaw 231 as smoothly as possible while pushing the air to the outside through the 334.

A water outlet 341 is formed at the end of the guide rod 340, that is, the portion surrounding the end of the rod 312.

The second body 400 according to the present invention consists of a rotary lever 410 having a thread 411 on the inner wall, and a fixing part 420 mounted to the lower portion of the rotary lever 410, thereby rotating the lever 410. In addition, the rod 312 of the piston rod 310 is screwed with the rod 312 so as to slide in the direction of the toothpaste storage portion 210 of the first body 200 by the rotation of the screw, The rod 340 plays a role of fixing and seating in a space provided between the partition walls 421.

In other words, the second body 400 has a rotation lever 410 coupled to the fixing part 420 so as to be freely rotatable in both the forward and reverse directions, and the partition wall 421 in the inner space in the state coupled with the rotation lever 410. It consists of a fixed portion 420 installed.

The rotary lever 410 is provided with a thread 411 on the inner wall to allow the thread 313 of the rod 312 and the thread engagement, so that the rod 312 can be moved in a straight direction.

The rotation lever 410 forms a plurality of recesses 412 at regular intervals around the outer surface to prevent the hand from slipping when the user holds the rotation lever 410 and rotates it.

Referring to the coupling relationship and action of the piston rod assembly 300 and the second body 400 made in this configuration as follows.

The piston rod assembly 300 has the second body 400 by the partition wall 421 of the guide rod 340 with the thread 313 of the rod 312 threaded to the thread 411 of the rotation lever 410. Is housed in a space formed in At this time, the space generated by the partition wall 421 is formed to correspond to the shape of the guide rod 340 so that the end portion of the guide rod 340 in the space is fixed without being rotated or flow.

In addition, the guide head 330 is inserted and coupled to the coupling jaw 231 of the first body 200 and at the same time, the guide head 330 is more firmly coupled to the first body 200 by the stopper 333. It is also fixed in a state that does not rotate. Since the upper and lower portions of the guide 320 are fixed to the first and

second bodies

200 and 400, respectively, when the rotary lever 410 is rotated, only the rod 312 is along the thread 411 inside the rotary lever 410. Passes through the rod receiving hole 332 of the guide head 330 to the space in the first body 200, that is, the toothpaste storage unit 210 to provide a compressive force to the piston head 250, the rotary lever 410 The rod 312 may be linearly moved while being drawn out in the direction of the first body 200 or drawn into the guide rod 340 according to the rotational state of the forward and backward directions.

In addition, the guide rod 340 has a structure for accommodating the pressing head 311 and the rod 312 of the piston rod 310 by the pressing head receiving groove 331 and the guide rod 340, respectively, Since only the piston rod 310 is linearly moved in an environment in which the 340 is fixed to the first and

second bodies

200 and 400, the piston rod 310 prevents the smooth movement of the linear rod and prevents the rod from moving smoothly. It is possible to seek safety for the mobility of (312).

In addition, the end portion of the rod 312 is not formed with a thread so that the rod 312 is moved to the first body 200 as much as possible, so that the screw thread 313 can be idling without damage by the forced rotation. It is made to ensure the durability of the rod 312.

If water penetrates into the first body 200, the guide rod is guided to a gap between the rod receiving hole 332 formed in the pressing head receiving groove 331 of the guide head 330 and the pressing head 311. 340 flows out to the water outlet 341 formed at the end to send water to the end of the second body 400, and since the water outlet 422 is formed through the end of the second body 400, the water is smoothly moved to the outside. Can spill.

In other words, when water is accumulated in the toothbrush, it is not hygienic, and thus suggests a structure that can be smoothly discharged to the outside when water penetrates into the first and

second bodies

200 and 400 during the brushing process.

As described so far, the configuration and operation of the toothbrush embedded in the toothpaste according to the present invention have been expressed in the above description and the drawings, which are merely examples, and the spirit of the present invention is not limited to the above description and the drawings. Various changes and modifications are possible without departing from the spirit of the invention.

The present invention is a toothbrush that can be mass-produced through a mold or various other processes, of course, there is industrial applicability.
