Description

Toothbrush for water spray

The present invention relates to a toothbrush for water injection, and more particularly, it is possible to bury the bristles with water or to spray the appropriate amount of water with the bristles as needed, not only can greatly improve the ease of use, but also toothpaste is hardened. The present invention relates to a toothbrush for water spraying, which can be used for various purposes by using sprayed water, and to facilitate brushing regardless of gender and age.

Toothbrushes are oral hygiene products used with toothpaste. Previously, only the bristles were formed on one side of the toothbrush bar, but recently, various types of toothbrushes have been disclosed.

On the other hand, when brushing with a conventional toothbrush is generally brushed with water after brushing the brush head.

However, when brushing after brushing the bristles with water, the following problems may occur.

First, when toothpaste is applied to the bristles when the toothbrush is moistened with water, the toothpaste may fall off the bristles even before the bristles enter the mouth.

Second, when the lack of water in the middle of brushing, not only toothpaste may not be applied to the tooth well, the gums may be damaged by the bristles of the gums, which may result in poor brushing.

Third, if the toothpaste is too hard, even the adult will have no choice but to brush well, especially children do not actively resolve this condition and often stop brushing easily, it can be an obstacle to oral cleaning.

As a result, when brushing with an existing toothbrush, various problems as described above may occur, there is a need for a new concept toothbrush that can solve all of these issues.

Is an enlarged view of the toothbrush body.

Referring to these drawings, the toothbrush 100 for water spraying according to the present embodiment can be buried in the bristle 111 as needed, or to spray an appropriate amount of water to the bristle 111, greatly improving the convenience of use. Not only can be used, but also can be used for various purposes by using the water sprayed, such as to prevent the toothpaste is hardened, and furthermore, to allow for easy and effective brushing regardless of age and gender, toothbrush head that is detachably combined with each other ( 110 and toothbrush body 140.

The toothbrush head 110 is the rest of the toothbrush body 140. The bristles 111 are provided at one end of the toothbrush head 110. Although the bristle 111 is illustrated in a straight line shape in the drawing, the bristle 111 may be curved, fine hair, or the like.

Toothbrush body 140 can be used a little longer, while the toothbrush head 110 has to be replaced when the bristle 111 is worn, at this time only replace the toothbrush head 110 instead of replacing the entire toothbrush 100 for water spraying This may be preferable in terms of cost.

Therefore, the toothbrush head 110 and the toothbrush body 140 is preferably detachably coupled to each other. At this time, the first and second detachable coupling portions 115 and 145 of the toothbrush head 110 and the toothbrush body 140 may form a hook type or screw type coupling structure.

Inside the toothbrush head 110 is formed a water flow line 120 toward the bristles 111. The water flow line 120 forms a line to spray the water stored in the water storage unit 141 in the toothbrush body 140 to the bristle 111 region.

The water flow line 120 is branched from the main connection line 121 and the bristle 111 in the area where the bristle 111 is located, and the main connection line 121 is connected to the water storage unit 141. It may include a plurality of branching water spray line 122 is disposed.

In the present embodiment, two branching water spraying lines 122 are applied, but three or more branching water spraying lines 122 may be applied.

As such a plurality of branching water injection line 122 is applied, there is an advantage that can supply the appropriate water evenly in the oral cavity.

On the other hand, the toothbrush body 140 is detachably coupled to the toothbrush head 110, the water storage unit 141 is formed therein to store the water to be flowed to the water flow line 120.

Thus, when pressure is applied to the water storage unit 141 of the toothbrush body 140 in the P direction of FIG. 2, water stored in the water storage unit 141 is transferred to the bristles 111 region through the water flow line 120. Can be sprayed.

When water is sprayed in the bristles 111 region as in the present embodiment, it can be utilized for various purposes by using the sprayed water, such as to prevent the toothpaste is hardened, and furthermore, it can be easily and effectively brushed regardless of age and gender. In particular, it may be utilized for the purpose of washing the bristle (111).

One sidewall of the toothbrush body 140 in the present embodiment forms a shape maintaining wall 142 made of a plastic material of a predetermined thickness. This is because the toothbrush body 140 must be gripped with a finger. The shape maintaining wall 142 may include means for preventing slipping.

On the other hand, the other side wall of the toothbrush body 140 forms a tube wall 143 made of a rubber material so that a pressing force can be provided to the water storage unit 141. Therefore, it is advantageous to press the tube wall 143 with a thumb or the like in the P direction of FIG. 2. In particular, when brushing in the state holding the toothbrush body 140 can naturally pressurize the tube wall 143, so water can be sprayed to the bristle 111 region from time to time can be excellent brushing effect.

On the other hand, in order to fill the water storage unit 141, the water injection unit 150 may be detachably coupled to the toothbrush body 140. In this embodiment, the water injection unit 150 may be coupled to the shape maintaining wall 142.

The use of such a water jet toothbrush 100 will be described.

First, the product is separated and filled with water in the water storage unit 141 through the water injection unit 150, and then coupled to the toothbrush head 110 and the toothbrush body 140.

Then, after applying an appropriate amount of toothpaste to the bristle 111, the toothbrush body 140 is held and brushing.

As the brushing proceeds naturally, the tube wall 143 may be naturally pressurized, and thus water may be sprayed to the bristles 111 region through the water flow line 120 as pressure is applied to the water storage unit 141. have. Therefore, the effect of brushing can be increased.

According to the present embodiment having the structure and action as described above, it is possible to bury the bristle 111 as needed, or to spray the appropriate amount of water to the bristle 111 can greatly improve the ease of use. In addition, it can be used for various purposes by using water sprayed to prevent toothpaste from hardening, and furthermore, brushing can be easily and effectively performed regardless of age or gender.

Particularly, in the case of a child, the toothpaste on the brush head 111 can be naturally supplied without brushing water even though the toothpaste is hardened by singing or deafening during brushing, so brushing is stopped or brushed in a dry state. It can eliminate the disadvantages.

In particular, in this embodiment, since only the bristle 111 region needs to be replaced, the value as an economy product can be improved.

6 is an exploded cross-sectional view of the toothbrush for water jet according to the second embodiment of the present invention, Figure 7 is an enlarged view of the toothbrush body shown in FIG.
