Abstract

The present invention relates to an electric toothbrush, and more particularly, to the end of the cylindrical brush is rotated to form a vertical direction with the teeth (齒牙) to facilitate the treatment of food sandwiched between the teeth. will be.

In the above-described present invention, the battery 22 and the motor 21 are mounted inside the case 20, and the electric toothbrush 10 rotates the brush of the toothbrush head 30. Cylindrical sole 31 is coupled to the upper portion of the rotating shaft 21a so that the end of the sole 31 is rotated to form a vertical direction with the teeth, and the outer half of the cylindrical sole 31 has a semi-elliptical protective cover 40. ) Is coupled to protect the sole 31, the motor 21 is composed of a forward, reverse rotation motor to be achieved by the electric toothbrush, characterized in that the cylindrical brush 31 can be forward, reverse rotation. It can be.

Description

Electric toothbrush

In general, the electric toothbrush is an electric motor-driven toothbrush that can rotate the toothbrush by electric power or shake it to clean the teeth, and to strengthen the gums by vibration, it is one of the toothbrushes widely used by the general public.

However, in the conventional electric toothbrush, as shown in Figure 1, the flat brush (2) forming a flat end in the toothbrush head (1) forming a small circle is rotated in contact with the teeth, food is sandwiched between the teeth Pulmonary bleeding did not come out well.

Furthermore, in the conventional toothbrush, since the brush is rotated only in one direction, when a lot of food is jammed, such as a corner, the toothbrush may not be effectively processed by only one direction rotation of the toothbrush.

The present invention has been made in view of the above problems, the object of which is the end of the cylindrical brush is rotated to form a vertical direction with the teeth (齒牙) is an electric motor that can easily handle food sandwiched between the teeth It is in providing a toothbrush.

A feature of the present invention for achieving the above object is, in the case of the electric motor brush 10 is mounted to the inside of the battery 22 and the motor 21, to rotate the brush of the toothbrush head 30 The upper end of the rotating shaft 21a of the motor 21 is coupled to the cylindrical sole 31 so that the end of the sole 31 is rotated to form a vertical direction with the teeth (齒牙), the outside of the cylindrical sole 31 A semi-elliptical protective cover 40 is coupled to protect the sole 31, and the motor 21 is configured as a forward and reverse rotation motor so that the cylindrical sole 31 can be forward and reverse rotation. It can be achieved by an electric toothbrush.

According to the present invention as described above, when holding the case 20 horizontally and brushing the teeth, the ends of the cylindrical brushes 31 are rotated in the vertical direction with the teeth (齒牙) while the food waste sandwiched between the teeth. Since they are easily removed, the efficiency of the brushing operation can be improved and the convenience of use can be enhanced, and the semi-elliptical protective cover 40 protects the inside of the mouth from the brush 31 which is rotated while being generated when brushing. As it can effectively prevent the scattering of water has the advantage of increasing the external competitiveness of the electric toothbrush as much as possible.

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

2 to 4, the battery 22 and the motor 21 are mounted inside the cylindrical case 20, and the brush mounted on the toothbrush head 30 by the power of the motor 21 is mounted. It is configured to rotate.

Of course, the electric toothbrush 10 made of the above-described configuration is known in the art. However, the most important feature in the present invention is that the cylindrical brush 31 can be rotated to form a vertical direction with the teeth.

That is, a cylindrical sole 31 is coupled to an upper portion of the rotation shaft 21a of the motor 21, and the tip of the sole 31 is rotated to form a vertical direction with the teeth.

A semi-elliptical protective cover 40 is coupled to the outside of the cylindrical brush 31, and the protective cover 40 covers the rotating sole 31 to protect the inside of the mouth while splashing water generated when brushing teeth. It is configured to prevent.

The motor 21 is composed of a forward, reverse rotation motor is configured so that the cylindrical sole 31 can be rotated forward, reverse, press the button 23 mounted on the case 20 once, forward rotation, 2 It is configured to stop once and reverse three times.

According to the present invention having the above-described configuration, when holding the case 20 horizontally, the teeth of the cylindrical brushes 31 are sandwiched between the teeth while the ends of the cylindrical brushes 31 are rotated in the vertical direction. Since it can be easily removed and damage to the gums is prevented, the efficiency of brushing work can be improved and the convenience of use can be improved. The semi-elliptical protective cover 40 is inside the mouth from the rotating brush 31, that is, the cheeks and the like. While protecting the tongue, it is possible to effectively prevent the splashing of water generated when brushing, such as to increase the external competitiveness of the electric toothbrush as much as possible.

In addition, when the button 23 mounted on the case 20 is continuously pressed, the cylindrical brush 31 rotates forward, stop, and reverse, so that the upper and lower teeth are easily operated by rotating the button 23. It is very convenient to use because it is different direction.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
