Description

Toothbrush {a tooth brush}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tooth brush, and more particularly, to a curved surface such as teeth and gums by buffering a brushed plate according to the washing direction of the toothbrush in the up, down, left and right directions during use of the toothbrush. The present invention relates to a toothbrush that can be washed while damaging the gums of the teeth as well as the teeth by allowing the brush to be properly contacted, and prevents foreign matters from being blown around the brush plate.

The toothbrush we use basically consists of a brushed toothbrush body and a gripping portion extending from the body. In the meantime, various types of gum damage prevention toothbrushes have been attempted to prevent damage to teeth and gums.

An example of a toothbrush of tooth damage prevention by such brushing is known as the toothbrush of Korean Utility Model Publication No. 94-5243.

The toothbrush is a lower plate which is a part of a toothbrush body having a predetermined recessed portion formed so that the upper plate is raised by being brushed and the bottom plate is raised, and a lower end of the brush which is located between the upper and lower plates and exposed to the bottom of the upper plate. It is made of a structure that accommodates therebetween an elastic plate which makes this contact possible and maintains elasticity.

Therefore, the brushed part that has passed through the hair follicle has a function of correspondingly contacting according to the curved surface of the tooth while being brought up and down through the hair follicle of the upper plate to contact the ridge of the elastic plate.

However, there is an unsanitary problem that the foreign body is introduced into the inside of the brushed pores during the use of the toothbrush, so that foreign matters decay when used for a long period of time. In case of raising and lowering of the raising part, there are also disadvantages that are hard to expect.

In particular, such a conventional toothbrush

First, a predetermined section at the bottom of the raising part should have a structure that can be moved smoothly through the pores,

Secondly, a brushed plate in which the raised pores are formed to be able to move up and down is required.

Thirdly, an elastic plate is required at the bottom of the raising plate to form an elastic ridge exactly corresponding to the rear end of the raising part.

Fourth, the position of the recessed part of the bottom lower plate of the toothbrush body located at the bottom of the elastic plate should exactly match the elastic melt part,

Fifth, there is a problem in that the assembly structure is complicated compared to the function of the toothbrush because all the above structure must be assembled into each component.

The present invention has been made in view of the problems of the conventional toothbrush, and has an object to provide a simplified brush plate structure that eliminates the up-and-down action of brushing itself.

An object of the present invention is to provide a toothbrush in which the buffering function of the brushed part is guaranteed even if the configuration for elastically responding to the brushed part is less accurate.

An object of the present invention is to provide a shock absorbing toothbrush having a simpler assembly structure for constituting the brushed, brushed plate, elastic plate, lower plate.

It is an object of the present invention to provide a toothbrush of a more hygienic structure, such that the coupling structure of the bottom of the raising plate and the toothbrush body is sealable so that foreign substances do not remain.

An object of the present invention described above is composed of a flexible material having a high elasticity and excellent restoring force, and brushed plate having a brushed portion; And a raising plate receiving portion for forming a recess portion and accommodating a portion of the raising plate in the recess portion so that a space is formed between the inner bottom portion of the recess portion.

It is preferable that the recessed part of the raising plate receiving portion and the raising plate have a two-stage coupling structure. In addition, the present invention preferably has a curved shape in which the bottom of the raising plate is convex upward toward the center, so that the present invention can appropriately correspond to the cylindrical contact surface of the contact surface with the teeth. The raising plate of the present invention is preferably made of silicon. Preferably, the space of the present invention is maintained such that the bottom of the raising plate does not come into contact with the inner bottom of the groove when the raising plate is pressed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing a state in which the body and the raising plate is separated before the manufacturing of the toothbrush of the present invention, Figure 2 is a cross-sectional view in a first direction of the bonded state of the toothbrush of the present invention, Figure 3 is a toothbrush of the present invention It is a cross-sectional view of the second direction in the bonded state after manufacture.

The present invention according to the drawings described above is extended to one side of the toothbrush body 5 to form a predetermined space (a) raising plate receiving portion 4, and raising plate coupled to the raising plate receiving portion 11 It consists of (3).

The raising plate accommodating part 4 forms the recessed part 11 into which the raising plate 3 is inserted. The recess 11 has a structure for accommodating a part of the raising plate 3 so that a space a is formed between the inner bottom of the recess 11 when the raising plate 3 is coupled.

A partly accommodating structure of the raising plate 3 is possible as the jaw portion 12 formed on the inner circumferential surface of the raising plate receiving portion 4. Preferably, the jaw portion 31 is also formed at the bottom of the raising plate 3 so as to correspond to the jaw portion 12.

Therefore, the raising plate 3 is combined while being put in the recess 11 of the raising plate receiving portion 4. At this time, the raising plate 3 is placed in the jaw portion 12 of the raising plate receiving portion 4 to form a space a between the bottom of the raising plate receiving portion 4.

When the raising plate 3 is put into the concave inlet portion 11 of the raising plate receiving portion 4, it requires a predetermined sealing structure. As such a sealable bonding method, a predetermined bonding method is applied.

4 is a cross-sectional view showing a state of use according to the first direction cross-sectional view of the toothbrush of the present invention, Figure 5 is a cross-sectional view showing a state of use according to the second direction cross-sectional view of the toothbrush of the present invention. According to these drawings the working example of the present invention will be described.

The present invention can brush the foreign matter in the gap between the teeth while reducing the contact force of the teeth while the brushed surface (2) appropriately corresponds to the curved surface to the curved surface with the connection between the tooth 100 and the tooth (100). Therefore, the raising acts to appropriately reduce the contact force in the protruding portion, and to increase the contact force appropriately in the gap.

In the accompanying drawings of the present invention, Figure 5 shows an example of the action of the tooth surface and brushing.

That is, the brush plate having a soft material and excellent restoring force has a space in which the jaw portion 31 is seated on the jaw portion 12 formed along the inner circumferential surface of the recess 11 of the brush plate receiving portion 4 in the state of raising the brush. (a) is secured, and this space (a) provides the appropriate cushioning force required for contacting the teeth as described above as well as the indentations between the teeth. In the case of a toothbrush having such brushed plate, the brushed body is divided into soft and hard, and even if the toothbrush is not selected, it is sufficiently reinforced by the buffering force of the soft material of the brushed plate. In the present invention, a brush plate made of a predetermined soft material is used in order to properly serve the brush plate. As the soft material, a silicon material known at present is preferable.

This action of the present invention is accompanied by the action of the bottom surface of the raising plate jagged to the space (a) in response to the more protruding tooth surface, and the gap between the teeth. Therefore, due to the brushed structure that always maintains a constant surface during contact with the teeth as in the prior art, the tooth surface is cut off unnecessarily or when the gum is unnecessarily washed to clean the tooth surface. The effect is to reduce work.
