Full-tooth automatic toothbrush

Abstract

The invention relates to a full-tooth automatic toothbrush. The full-tooth automatic toothbrush comprises a driving motor, a power supply, a control device and a brush head; the brush head is arc-shaped and can be contained in an oral cavity; semi-surrounded brush surfaces are arranged up and down along the shape of the brush head; and each brush surface is provided with an inner-tooth brush surface, an outer-tooth brush surface, an occlusion brush surface and a hair-planting beam. The electric toothbrush can clean maxillary teeth and mandibular teeth simultaneously, and the driving motor is positioned on the inner side of the brush head. The invention provides the electric toothbrush which is higher in efficiency and convenient to operate, accords with the physiological structure of a human body and can correct bad tooth-brushing action to avoid tooth injury; and through setting of the motor position, the kinetic energy of the motor can be effectively transmitted, the brush head adheres to the teeth well, and cleaning dead corners are avoided. In the use process of the full-tooth automatic toothbrush, double hands can be liberated.

Description

[0001] Technical field: [0002] The invention relates to an electric toothbrush, in particular to an electric toothbrush which can be placed in the oral cavity to simultaneously clean the upper and lower teeth, and belongs to the field of oral care. [0003] Background technique: [0004] Due to the advantages of high efficiency compared with traditional manual toothbrushes, electric toothbrushes are becoming more and more popular among consumers. [0005] At present, electric toothbrushes and traditional manual toothbrushes have a small contact area between the toothbrush head and the teeth. The bristles on the toothbrush head are generally flat, and can only effectively brush two or three teeth at a time, because a normal adult has 32 teeth. In fact, the brushing efficiency is very low like this, even if an electric toothbrush with a rotating brush head on the market is used, the same problem exists. [0006] Since the tooth axis is a basically vertical physiological struct...

AI Technical Summary

Problems solved by technology

[0006] Since the tooth axis is a basically vertical physiological structure, the gap between each tooth requires the toothbrush to move up and down to effectively clean the foreign matter in it, and because the movement of the toothbrush driven by many people's arms and wrists is not correct, it will be damaged over time. tooth damage

[0007] In addition, during the process of brushing teeth, it is necessary to continuously change gestures according to the shape of the dental arch, which will cause great inconvenience to people with limb movement disabilities

[0008] According to the patent submitted by me, the invention titled the manufacturing method of the electric toothbrush and the brush head, the brush head is arc-shaped and can be contained in the oral cavity. One internal tooth bristle surface, multiple external tooth bristle surfaces, multiple occlusal bristle surfaces, and respectively have hair-planted bundles, which can clean the upper and lower teeth at the same time. There is such a problem in the technology of this structure, because the motor is located in the handle. Inside, the handle also has a power supply. These two parts are relatively heavy, and the brush head is relatively light, resulting in a lever force between the motor and the brush head. The motor drives the brush head to move through the connecting rod on the brush head, but because the motor is located outside the brush head , the movement of the motor cannot be effectively transmitted to all parts of the brush head, resulting in too large local movement strokes of the brush head, and too small local movement strokes, which cannot effectively clean the tooth surfaces of various parts

In addition, the motor described in this patent is connected to the connecting rod through the motor shaft, and the handle needs to be held by hand during use, which is not a fully automatic toothbrush.
