Description

Toothpaste embedded toothbrush

The present invention relates to a toothpaste embedded toothbrush, and in particular, a toothpaste extrusion structure and at the same time the user can achieve a structure to accurately extrude one toothpaste usage, and also replace the brush head refill embedded 2-3 times toothpaste Toothpaste embedded toothbrush that can be used semi-permanently the body is possible.

In general, after eating, a part of the food is retained in the interdental area, and fine food residues remain in the tongue of the oral cavity. Therefore, when ingesting food or drink, it is recommended to brush teeth within 3 minutes. The purpose of these brushing is to prevent food residues from remaining inside and outside the teeth and occlusal surfaces, and more precisely to remove plaque, a colorless membrane that continues to stick between teeth and gums.

However, if you do not brush your teeth in the right way at the right time, oral cavity, gums, tongue, etc., inflammation and swelling may cause bad breath or gingivitis or tooth decay.

In other words, human teeth seem to be hardened on the surface, but they are living tissues like other parts of the body, and acid is generated when the parasitic bacteria in the oral cavity act on the sugars in the food residues that remain between the interdentals after eating. These acids melt the enamel layer protecting it, causing bacterial destruction, or tooth decay.

Therefore, in order to prevent such oral diseases or to prevent the spread of oral inflammation or tooth decay, fluoride that can prevent tooth decay by reducing the diet suitable for oneself, for example, sugary foods or increasing its resistance to acid erosion. It is necessary to brush teeth while using functional toothpaste such as toothpaste containing toothpaste or a herbal ingredient having antibacterial action.

However, when looking at these brushing habits, most people brush their teeth with a lot of toothpaste on the surface of the toothbrush, and in this case, the toothpaste on the surface of the toothbrush is mixed with saliva or water, and bubbles form at once. The bubbles will fill up and spit out before the brush is finished.

In this case, children, especially children who don't like to brush their teeth, will spit out even a little foam in their mouths.

Therefore, in order to brush teeth effectively, it takes about 3 minutes to brush every corner of the gum, so it is desirable to apply the toothpaste deeply to the toothbrush and then to the toothpaste on the toothbrush slowly melted from the top and discharged to the end of the toothbrush during brushing. Do. Therefore, there is a need for a new method or device for automatically dissolving toothpaste slowly.

On the other hand, the proper amount of toothpaste is known to be about 3g at a time, but due to the influence of excessive toothpaste advertisement through the mass media of toothpaste companies, the amount of toothpaste was wasted a lot because it is actually used several times. It is becoming. Therefore, there is a need for a method or apparatus for inducing only an appropriate amount to be used at a time.

Moreover, when using the proper amount, it is necessary to use the toothpaste deeply buried in the toothbrush, but it is not easy to keep it, so a new method is required to induce it to be automatically or compulsory.

Another way to save toothpaste is to use a toothpaste extruder that makes it easy to use all the toothpaste remaining in the toothpaste container when the toothpaste is almost exhausted, but in this case it requires a separate purchase and is cumbersome and removable. There is no surname.

In addition, in the past, a number of toothpaste-type toothbrushes that can be easily carried by incorporating toothpaste in the toothbrush as disposable toothbrushes or portable toothbrushes when traveling are proposed.

Such toothpaste-type toothbrush has a brush (4) formed in the toothpaste filled in the inner space by moving the sliding knob (3) to the toothpaste (1) embedded in the body (2) as shown in FIG. Extruded to (5) and discharged between the brushes (4) through the discharge port (6) (see Korea Patent Registration No. 78348).

The one-piece structure is difficult to refill the toothpaste (1) in the space inside the body at the same time the brush body (2) is large and the elasticity of the neck is reduced due to the secure space for accommodating the toothpaste and the linear sliding structure for toothpaste extrusion It has a structure that can not be used to refill toothpaste. In addition, the above-described structure has a problem in that the replacement of the brush 4 is impossible when the brush 4 is worn using a toothbrush for a certain period of time and thus has a short lifespan.

In addition, there are a number of prior arts in addition to the above-described prior art, but a structure that can simultaneously solve the above-described problems has not been proposed.

For example, portable toothbrushes such as Utility Model No. 97-26583 (portable toothbrushes with writing instruments and toothpaste) and Utility Model Publication No. 95-267 (portable toothbrushes with toothpaste compartments) are simply compacted with toothpaste in one case. When storing or using toothpaste embedded in the body, the brush head can be removed, buried, and reassembled to respond. It does not have a substantial toothpaste structure.

In addition, the technology for extruding toothpaste by pressing the user's hand according to the driving source for extruding toothpaste is Utility Model Publication No. 94-6414, the technology using air tube and air tube pump is applied to Utility Model Publication No. 95-266, restoring force of compression spring. The technique used is disclosed in Utility Model Publication No. 95-265.

This prior art also has a structure that is difficult to use a proper amount of toothpaste and difficult to refill toothpaste or refill of the brush head.

Therefore, the present invention has been made in view of the problems of the prior art, the purpose of which is to embed the toothpaste extrusion structure and at the same time the user pushes the amount of toothpaste accurately and presses the pocket holder, the push rod is returned to the structure again It is possible to achieve and also to replace the brush head refill with a built-in toothpaste 2-3 times to provide a toothpaste-type toothbrush that can be used semi-permanently the body.
