Problems solved by technology

Among them: the main disadvantage of traditional forms of toothbrushes such as manual and tongue-driven toothbrushes is that they must be learned and used consistently to gradually form the correct brushing method, and it is not easy to clean all the inside and outside of the gums; electric toothbrushes generally use reciprocating rotation The form of brushing itself does not have the conditions for smooth brushing, and it often hurts the gums due to improper force control; high-tech toothbrushes such as electromagnetics cannot be widely used in a short period of time due to high production costs; Brush, can not automatically switch the brushing direction of the roller brush inside and outside the teeth, can only be adjusted by the user at any time, therefore, there is also the hidden danger of reverse brushing and gum injury caused by the user's misjudgment

Embodiment Construction

[0014] specific implementation plan

[0015] Use a group of batteries (1) to provide power to the micro motor (2), the gear of the micro motor drives a gear reduction transmission device (3), the output speed is reduced to the safe range after passing through the reduction device, and the reduction device drives a pair of One of the transmission rod plugs (4) meshing with each other and the other transmission rod plug will rotate in the opposite direction under the gear movement of the previous one, thereby forming a pair of transmission rod plugs that rotate counter-rotatingly. The pair of transmission rod plugs that rotate counter-rotatingly drive a flexible transmission rod (5) to rotate respectively. ~ 85 degree forward angle of roller brush (7). The middle part of the pair of roller brushes is not bristled, and is engaged with the fixing device (8).

Abstract

A 3-D electric tooth-brush able to brush the internal and external surfaces of teeth by rolling at the same time is composed of a pair of flexible drive rods, a pair of brushes rolling in opposite directions, a pair of handles, and a top plate with bristles on its inner surface for brushing the chewing surface of tooth. Its advantages are correct brushing method, overall brushing of teeth surfaces and gap seams, no damage to gingixa, and high cleaning effect.

Description

technical field [0001] The invention relates to an electric toothbrush, in particular to a three-dimensional electric toothbrush capable of rolling and brushing the inside and outside of teeth at the same time. Background technique [0002] There are many types of toothbrushes used in people's daily life. Among them: the main disadvantage of traditional forms of toothbrushes such as manual and tongue-driven toothbrushes is that they must be learned and persisted in order to gradually form the correct brushing method, and it is not easy to clean all the inside and outside of the gums; electric toothbrushes generally use reciprocating rotation The form of brushing itself does not have the conditions for smooth brushing, and it often hurts the gums due to improper force control; high-tech toothbrushes such as electromagnetics cannot be widely used in a short period of time due to high production costs; The brush can not automatically switch the brushing ...
