Description

[Detailed description of the invention] The present invention relates to a toothbrush for brushing teeth, and is an improvement to the conventional toothbrush that does not have a handle to be held in the hand and can be brushed by squeezing the upper and lower teeth during the day. Toothbrushes were equipped with a long handle that was attached to the brush base at the tip of the toothbrush so that the brush base could be supported by hand, and the brush base could be moved up and down during the day by holding this handle. I used to brush my teeth.

Therefore, you cannot brush your teeth without using your hands, and
Because the handle protrudes outward during the day, polishing fluid such as saliva and water from the mouth may run down the handle while brushing the teeth. Because it extends in the direction perpendicular to the tooth, it is necessary to brush the upper and lower teeth or the front and back of each tooth separately, and to brush all the teeth thoroughly. There are various drawbacks such as having to hold the handle with either the right or left hand and turning the brush base so that the brush base always touches the teeth while brushing.

In addition, in conventional toothbrushes of this type, there are those that have a removable toothbrush base at the tip of the handle, and the toothbrush base that is detached from the handle, and those that have brushes on opposite sides at the tip of the handle. There were toothbrushes whose base rotated by operating the handle.

These brushes do not have opposed brushes that move vertically or longitudinally independently of each other, but instead have a configuration that universally adapts to all upper and lower tooth rows that differ in shape from user to user. It wasn't something to do.

This invention was devised as an improvement in view of these shortcomings.
A brush is provided on one side of a pair of main bodies made of elastic material, and a protective brush is provided on the circumferential side of each main body, and the brush surfaces of the two main bodies are faced to each other, and the centers of the side bodies are connected by a connecting member. The side bodies are configured to be movable by the members, and the protective brush provided on the peripheral side of the body alleviates the discomfort during the day.
The purpose of this brush is to protect and clean the upper and lower gums, and to adapt to the upper and lower dentition of all types of users with the brush on the side body that can be freely moved up and down and back and forth using a connecting member. There is.

Next, drawings showing embodiments of the present invention will be described.

Figures 1 and 2 show an embodiment of the present invention.
is a substantially circular body made of an elastic material such as rubber, and the body 1
A brush 2 is provided on one side of the main body 1, and a protective brush 3 is provided on the peripheral side of the main body 1.

A recess 4 is formed in the center of one side of the main body 1 on which the brush 2 is provided.

In order to connect the two main bodies 1 with their respective brush surfaces facing each other, one end of a spring 5, which is a connecting member, is fixed to the bottom of the recess 4 of one main body 1, and the spring 5, which is a connecting member, is similarly connected. 5 is fixed to the bottom of the four parts 4 of the other main body 1, and each brush surface of the side main body 1 is connected to face each other.

Therefore, when using, after adding an appropriate amount of toothpaste, paste, solid toothpaste, etc. to each brush 2 of the side body 1, and during the day, apply each of the side bodies 1 connected to the upper and lower teeth a. Place it between the brushes 2 and make a biting motion with the upper and lower teeth a.

The main body 1, which is made of an elastic material such as rubber, slightly deforms its shape due to the biting force of the upper and lower teeth a from above and below, and moves in the up-down and front-back directions along the upper and lower rows of teeth and the shape of the teeth. It moves so that each brush 2 touches the upper and lower teeth a, and also expands and contracts from springs 5 or 7, which are connecting members, so that both brushes 2 press against the teeth. Just by biting together, you can thoroughly brush not only the top and bottom of your teeth, but also the front and back of your teeth at the same time.

The protective brush 3 provided on the peripheral side of the main body 1 alleviates discomfort during the day and is useful for protecting and cleaning the upper and lower gums.

In the above-mentioned embodiments, the connecting member of the side body is described as a spring, but the same effect can be achieved by using a connecting rod having elasticity such as rubber, and the present invention is not limited to the embodiments.

According to the present invention configured as described above, the side bodies can be freely moved in the vertical direction and the front-back direction through the connecting member by simply chewing with the upper and lower teeth during the day, and can be used by all kinds of users. The brush can be pressed against the row of teeth and the shape of the teeth, and can brush not only the top and bottom of the teeth, but also the front and back of the teeth at the same time.

In addition, since it does not require a handle like conventional toothbrushes, it eliminates the inconvenience of holding it in your hand, and when brushing your teeth, the polishing liquid does not flow through the handle and flow out of your mouth, making it easier to brush your teeth. This has effects such as being able to provide toothbrushes.
