Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toothbrush, and more particularly to a tooth plan with a built-in dentifrice that can dispense an appropriate amount of dentifrice to brush teeth with a one-touch operation.

Toothbrushes have been proposed many times in the past, in which a fluid dentifrice is contained inside the toothbrush, and when the teeth are brushed, the dentifrice is pushed out and oozes out from the bristles.

However, in the conventional type, the toothpaste charged in the handle is pushed out using a pushing member such as a piston, so the dispensing operation is not only troublesome, but also
There is a problem in that it is difficult to take out the appropriate amount of toothpaste that is needed. In addition, the type with a built-in extruder front inside the handle does not have a large space to store the toothpaste, and if it is a disposable type, for example, the toothpaste will run out sooner than the service life of the bristles, and it will inevitably occur. There is no choice but to replenish the toothpaste and obtain it. Furthermore, since the inner cone is used to completely isolate the living area from the inside of the handle, there is a risk that debris will flow back into the handle during the day when brushing teeth.
There were various drawbacks such as unfavorable surgical techniques.

In view of this, the present invention provides a toothbrush with a one-touch structure that dramatically improves the conventional toothbrush with a built-in dentifrice and provides a completely new structure and operational feeling that can eliminate the drawbacks of the conventional toothbrush. It was made for the purpose of

The characteristic structure of the toothbrush according to the present invention is that the toothbrush has four bristles on the tip side and the side of the handle that is held by hand.
The hair-planting rod itself with 1α bristles is connected so that it can be pushed down and operated, and by pressing down and operating this hair-planting rod, an appropriate amount of liquid dentifrice in a dentifrice container that forms a part of the handle oozes out onto the flocked surface to brush teeth. The reason is that we have made it possible to do this.

The present invention will be described below with reference to embodiments shown in the drawings.

As shown in the external appearance in FIG. 1, the toothbrush 1 according to the present invention includes an elongated portion 2 and a flocked rod 3 fitted inside the tip of the handle portion so as to be slidable in the axial direction. A dentifrice dispensing mechanism 4 (shown in FIGS. 2 and 3) is housed inside.

The handle portion 2 consists of a combination of a handle main body 5 and a dentifrice container 6 connected to the handle main body 5, and a male thread 6a formed on the outer periphery of the opening of the dentifrice container 6. It can be freely connected by screwing into a female thread 5a formed on the inner periphery of the base of the handle main body 5.

The tip of the hair-planting rod 3 is formed into a flat rectangular cross-section like that of a normal toothbrush, and bristles 7 are planted in a required range on the - side of the hair-planting surface 3a.

A dentifrice passage 8 having a hole structure is formed inside the advancement rod 3 from its base 3b to the flocking surface 3a, and this passage 8 communicates with the flocking holes of the bristles 7 planted on the flocking surface 3aK. , liquid dentifrice is exuded from the root portion of the bristles 7.

The base portion 3b of the flocking rod 3 is connected to the bearing portion 9 of the handle main body 5.
is slidably fitted as tightly as possible to the inner circumferential surface of the
A flocked rod 3. The hand grip protruding from the outer circumferential surface of the base 3b is slidably fitted with an operating protrusion 11 as tightly as possible, and the engagement between the vertical groove hole 10 and the protrusion 11 allows the flocking to be carried out. The rod 3 is prevented from rotating and steadying.

Further, an operating tube 12 of the dentifrice dispensing mechanism 4 is fitted and fixed to the base 3b of the flocking rod 3, and this operating tube 12 is connected to a bearing formed at the bottom of the bearing section 9 of the handle main body 5. Hole 13
It is inserted so that it can slide as tightly as possible.

The dispensing mechanism 4 including the actuating tube 12 is of a pump structure, an example of which is a tube fixedly connected to the handle body 5, as shown in cross section in FIGS. 2 and 3. A valve part 15, which is formed by expanding into a trumpet shape at the end of the actuating pipe 12, is inserted into the shaped valve case 14 so as to slide in contact with the end of the actuating pipe 12, and the rear end of the actuating pipe 12 and the valve case A compression spring 16 that includes the operating tube 12 and returns the flocking rod 3 to the protruding direction is interposed between the lower bottom of the rod 14 and the lower bottom of the rod 14 .

Ball-shaped valve bodies 17 and 1B are housed in the large diameter hole at the tip of the actuator v12 and the bottom of the valve case go 4, respectively. The valve body 18 in the valve case 14 opens and closes the mouth of a suction pipe 190 connected to the bottom of the valve case 14, and the valve body 17 of the operating pipe 12 opens and closes the mouth of the suction pipe 190 connected to the bottom of the valve case 14. The path end can be opened and closed to open and close the space between the passage and the dentifrice passage 8.

A micro-diameter air displacement hole is opened in the side surface of the valve case 14, so that air is replenished when the liquid dentifrice in the dentifrice container 6 is sucked into the valve case 14. Note that the pouring mechanism 4 is not limited to the illustrated embodiment, and may have other configurations.

In the figure, 21 indicates a liquid dentifrice.

Next, the operation of the above embodiment will be explained.

By holding the handle part 2 and pushing down through the operating protrusion 11 of the flocking rod 3, or by pressing the tip of the flocking rod 3, or by pressing the tip of the flocking rod 3 against something, The flocking rod 3 is pushed along the bearing part 9 of the handle main body 5, and the actuating pipe 12 is pushed together with it and enters the inside of the valve case 14. At this time, the valve body 17 is opened and the valve body 18
is closed. Then, when the compression of the flocking rod 3 is released, the flocking rod 3 protrudes and returns to its original state due to the action of the compression spring 16, and the operating tube 12
The pressure inside the valve case 14 becomes negative, and the liquid dentifrice in the container 6 is sucked into the valve case 14 through the suction pipe 19.

If you push down the flocking rod 3 again in the same way as above,
This time, due to the entry of the actuating tube 12, the dentifrice in the valve case 14 is pushed out through the actuating tube 12 and the dentifrice passage 8, and by releasing the pressure, the valve body 17 is closed, and the valve body 18 is opened to open the container again. Dentifrice is sucked into the valve case 14 from within the valve case 6.

By performing this operation 2 to 3 times in the initial stage of use, the valve case 14, the operating tube 12, and the dentifrice passage 8 are filled with toothpaste, and from then on, each time the flocking rod 3 is pressed, A dose of dentifrice oozes out through the bristle holes of the bristles 7 on the bristle-planted surface 3a, allowing teeth to be brushed. Please note that due to individual differences,
If the amount of exudation is insufficient, two or more suppression operations may be performed.

Also, when all the toothpaste in the toothpaste container 6 has been used,
By unscrewing the container 6 from the handle body 5, unsealing a new container 6, and screwing it back into the handle body 5, it can be used immediately and continuously.

As explained above, in the toothbrush of the present invention, the bristle-flocked rod is used as the operation part, and by pushing the bristle-flocked rod down against the handle body, an appropriate amount of toothpaste in the container can be exuded onto the bristle-flocked surface. Not only can you brush your teeth with a one-touch operation, but the amount of toothpaste that oozes out with a single operation is fixed, so you don't have to worry about manually distributing the toothpaste like in the past, and you don't have to brush an unnecessary amount of toothpaste. This prevents the agent from being wasted. In addition, by pressing down on the flocked part to pour out the toothpaste, a feeling of temperature and use can be obtained compared to conventional methods, and the dispensing operation can be performed freely by pressing down on the flocking rod. ,
It provides fun-7-Z as a tool for daily use, and can especially interest young children who dislike tooth brushing, and can greatly contribute to inculcating the habit of tooth brushing. Furthermore, since the toothpaste container can be easily attached and detached, the main body of the toothbrush can be used for a long period of time, and there are various advantages such as being economical.
