It consists of roughly.

First, the toothbrush rod 10 is composed of a bristles 12 having the bristles 12a implanted like the conventional toothbrush rods and a support 14 formed extending to the rear of the tufts 12. The toothpaste part 12 is discharged toothpaste is formed in the discharge port 16 for supplying the toothpaste to the bristles (12a), the location is the toothpaste is discharged to be evenly distributed to the bristles (12a) It is preferably located in the center of the).

In the toothbrush stand 10, a tube inserting hole 20 is formed from the discharge port 16 to the rear end of the support 14, and a tube 24 through which toothpaste passes is installed inside.

And, the nipple 18 is coupled to the discharge portion 16. The nipple 18 is formed with a horizontal ring 18a around a point spaced downward from the upper end by a predetermined distance, and an incision that vertically cuts the center from the upper point of the ring 18a to the end of the upper end ( 18b), and the material is preferably made of a soft synthetic resin material or silicone material, which is harmless to the human body.

The nipple 18 is opened and closed by the cutting portion 18b in accordance with the presence or absence of a force applied from the inside, and is opened by the force applied from the inside, and vice versa.

That is, when the toothpaste supply is required for brushing, the cutout 18b of the nipple 18 is opened by the air pressure applied from the pump at the rear, and the toothpaste is delivered to the bristles 12a. After the toothpaste supply is made, if the air pressure is removed, the incision 18b is closed by the elasticity of the nipple 18 itself, thereby preventing the transfer of toothpaste, as well as moisture remaining in the bristles 12a. Can be prevented.

The length of the nipple 18 is about 2/3 of the height of the bristles 12a, and is formed of a soft synthetic resin material. This is for the toothpaste to be smoothly supplied to the bristle 12a side, for smooth use. When the nipple 18 is formed to the same height as the bristles 12a, the end of the nipple 18 is worn out, and it is difficult to perform its function. When the nipple 18 is made hard, the flow of the bristles 12a is prevented. You can't brush softly because it interferes.

The handle portion 30 is formed in a tubular shape as a portion used by the user wrapped around the hand, may be configured integrally with the toothbrush rod 10, when the bristles (12a) are worn out and can no longer be used toothbrush itself It is also preferable to configure a separate type so that can be used interchangeably.

And it is apparent to those skilled in the art that the structure of such a connecting portion is not limited to the portion described as only one example, and may be variously screwed.

In addition, the rear end portion outer surface of the handle portion 30 is formed with a thread 34 that can be coupled with the pumping portion (40).

Toothpaste storage pack 36 in which the toothpaste is built into the handle part 30 is installed. The toothpaste storage pack 36 is formed of a cylinder and is formed of a cylinder (38) for embedding the toothpaste and a piston (38) for inserting the toothpaste inserted from the rear side of the cylinder (37).

The tip portion of the cylinder 37 is formed with an outlet hole 37a through which toothpaste is discharged. The outer diameter of the outlet hole 37a is increased from the front to the back, and the inner diameter is formed smaller from the back. As such, the outer diameter is configured to be inclined so that after using all the toothpaste stored in the toothpaste storage pack 36, a new toothpaste storage pack 36 may be purchased and used, but to make it easy to charge the toothpaste at home. When the toothpaste is filled by inserting the outlet hole 37a of the cylinder 37 into the outlet of the toothpaste tube, the toothpaste flows into the cylinder 37 without leaking the toothpaste.

The piston 38 has an outer diameter larger than the inner diameter of the cylinder 37 so that when the piston 38 is coupled to the cylinder 37, the piston 38 is fitted to the inside of the cylinder 37, and the external force does not act The piston 37 does not come off from the cylinder 37.

In addition, the piston 38 has a structure in which a soft wing (38a) is formed on the upper and lower end rim, and when the air pressure is applied from the rear portion, the piston 38 moves in close contact with the inner wall of the cylinder (37). Since it is kept confidential, the outside air does not flow into the toothpaste inside, there is no fear that the toothpaste is damaged.

On the other hand, the toothpaste storage pack 36 can be used interchangeably, the outlet hole 37a of the unused toothpaste storage pack 36 is sealed with aluminum foil. Therefore, when using, it is good to remove the aluminum foil and install it inside the handle part 30.

The tube 24 is inserted into the tube inserting hole 20 of the toothbrush rod 10 is formed in the front portion in the form of a square tube, the rear portion is formed in the form of a circular tube is inclined in the upward direction and is a horizontal structure. This is because the tube 24 is located in the inner tube insert 20 of the support 14 of the toothbrush rod 10, the rear portion is coupled in communication with the toothpaste storage pack 36 installed inside the handle portion 30 tube 24 In order to be inserted into the exit hole (37a) of the cylinder 37 is coupled to the rear portion of the), the toothpaste is to ensure a smooth supply to the bristle (12a) side, to prevent backflow.

In addition, the front portion of the tube 24 is formed to be loosely fitted to the tube insertion hole 20 of the toothbrush stand 10, and when the tube 24 is inserted into the tube insertion hole 20 and installed therebetween, A fine gap is generated, and the toothpaste enters the gap and serves as a binder for binding the two, so that the tube 24 and the tube inserting hole 20 are in close contact with each other, and the toothpaste inserting hole 20 which is a distribution passage of the toothpaste is sealed to the outside. .

It is preferable that the material of the tube 24 is made of a hard hard material or a material that can withstand the chemical composition of the toothpaste without change. One example of such a material may be made of stainless steel.

In addition, since the hard tube 24 is installed and used in the tube insertion opening 20 of the toothbrush stand 10, the toothbrush stand 10 is firm, and brushing is easy.

On the other hand, when the rear portion of the tube 24 is inserted into the exit hole 37a of the cylinder 37, the inner diameter of the exit hole 37a is configured to be narrowed as it enters. Does not fall well, and the exit hole is completely sealed so that there is no fear of outside air inflow.

Next, the pumping unit 40 will be described. The pumping portion 40 is coupled to the rear portion of the handle portion 30. The main function of the pumping unit 40 is to ensure a smooth supply of toothpaste. To this end, the air inlet 44 and the air discharge 46 is composed of, the concrete structure of the tubular housing formed with a thread (42a) is coupled to the threaded portion 34 of the handle portion 30 in the inner side An air inlet 44 for introducing external air is provided at the rear of the main body 42, and an air outlet 46 for discharging the internal air to the outside is provided at the side surface. When pressure is generated, sufficient pressure is generated by inflow of external air so that the toothpaste inside the toothpaste storage pack 36 is pushed forward, and when not in use, the internal air is discharged to the outside by simple operation, thereby delivering toothpaste due to useless residual pressure. This should not be done.

In addition, the O-ring 48 is provided inside the housing body 42 to maintain the airtightness of the pumping part.

The air inlet 44 has an inlet 44b through which air can be introduced into the rear part, and an inlet valve 44c capable of transferring air introduced into the front part into the housing body 42. It consists of the pumping ball 44a. The inlet valve 44c is formed by combining a cap 44e having a front end cut in a body 44d having a central portion thereof, and the cap 44e is provided only by a force applied from the inside, such as the nipple 18. It is open and is not opened by the force applied from the outside so that the air introduced into the housing body 42 does not flow out.

The air discharge portion 46 is installed on the side of the housing body 42, as shown in Figure 3, it consists of a release button 46a, a spring 46b, a stop ring 46c. As a force is applied to the release button 46a, the release button 46a pushes the stop ring 46c downward so that a gap is generated and the air remaining in the pumping part 40 is discharged to the outside by the gap. In the state where the air is completely discharged, the release button 46a is pushed up by the elastic force of the spring 46b, so that the stop ring 46c seals the internal space. Therefore, pressure is generated by the operation of the air inlet 44 so that the toothpaste stored in the toothpaste storage pack 36 is supplied to the bristles 12a, and when the supply of the toothpaste is to be stopped, the air outlet 46 is operated. By discharging the air inside the pumping unit 40 to the outside to prevent the toothpaste is discharged.

It will be described how to use the toothpaste automatic supply toothbrush 100 according to the present invention made of a structure as described above.

First, the toothpaste storage pack 36 located in the handle 30 of the toothbrush is stored a certain amount of toothpaste. Press gently while brushing the inlet 44b of the pumping ball 44a with a thumb for brushing. At this time, the air pressure is generated by the contraction of the pumping ball 44a so that the cut-out part of the cap 44e of the inlet valve 44c located in the forward part is opened, and the air inside the pumping ball 44a is pumped part 40 housing. It flows into the main body 42. As air is introduced, the pressure generated inside the pumping part 40 is applied to the rear surface of the piston 38 of the toothpaste storage pack 36.

The piston 38 discharges the toothpaste stored in the cylinder 37 to the outlet hole 37a of the cylinder 37 by the air pressure applied as described above, and the toothpaste is delivered to the tube 24 at the outlet hole 37a. do.

And the toothpaste delivered to the tube 24 is delivered to the discharge port 16 of the hair transplanting part 12, the nipple 18 located above the discharge port 16 is kept closed by its elasticity, but air pressure As the toothpaste is pushed upward by the incision 18b, the toothpaste leaves the nipple 18 and is delivered to the bristles 12a. Here, as the piston 38 of the cylinder 37 moves forward, the toothpaste is continuously discharged to a point where the air pressure inside the housing body 42 is in balance with the outside air pressure. When the internal and external air pressure is balanced, the cutout 18b of the nipple 18 is closed by its own elasticity, and thus no toothpaste is discharged.

If the toothpaste is to be discharged while the toothpaste is being discharged, press the release button 46a of the air outlet 46 to open the air outlet 46 to discharge the air inside the housing body 42 to the outside. Ensure that air pressure no longer acts on the piston 38.

Brushing is performed in the above state. In this case, since the nipple 18 is made of a soft silicone synthetic resin material, the nipple 18 flows together with the flow of the bristles 12a, so that soft brushing is possible. Unlike in the prior art, foreign matter such as moisture cannot be delivered to the nipple 18 even during brushing.

After all brushing is done, even when the toothbrush is cleaned, since the cutout 18b of the nipple 18 is kept blocked by its own elasticity, the penetration of moisture does not occur, thereby enabling efficient use. In addition, even when shaking to remove the water, unlike the prior art, since the cutout portion 18b of the nipple 18 maintains a closed state, the toothpaste from the ripple can be prevented from leaking outside, thereby enabling efficient use.

In addition, since the cutout 18b of the nipple 18 is also closed during storage, the external air is prevented from contacting the toothpaste existing inside the nipple 18 and the discharge port, thereby preventing hardening. In addition, since the horizontal ring 18a is formed in the nipple 18, even if it is used for a long time, the cutout 18b formed in the upper part no longer opens, and thus the nipple 18 can continuously perform its own role. have.

As described above, according to the present invention, the horizontal ring is formed at the upper end of the nipple so that the incision of the nipple is not cut beyond a certain range even if used for a long time, and the toothpaste is improved by improving the cylinder outlet hole of the toothpaste storage pack There is an easy effect of charging.

In addition, the toothpaste automatic supply toothbrush according to the present invention has the effect of free inlet and outlet air to the pumping unit.

The present invention is not limited to the above embodiments, and as claimed in the following claims, any one having ordinary knowledge in the field to which the present invention pertains without departing from the gist of the present invention can make various changes. Until the technical spirit of the present invention will be said.
