Omnidirectional scientific brush

Abstract

The invention provides an omnidirectional scientific brush, comprising a handle and a head. The head is of a U-shaped structure. A central gear set, a tooth outside bristle roller, a tooth inside bristle roller and a tooth end face bristle roller are mounted in the head. A power output mechanism driven by a miniature motor is disposed in the handle and drives the central gear set to rotate so that the tooth outside bristle roller and the tooth inside bristle roller on two sides of a same tooth rotate in opposite directions both from tooth root to tooth end, and rotational motion of the tooth end face bristle roller brushes end faces of upper and lower rows of teeth in the mouth along tooth gaps. A user can automatically finish washing all teeth at a time without manually controlling the head to move during tooth brushing, thus cleaning quality and efficiency of tooth brushing are greatly improved, time cost and labor consumption for tooth bushing are substantially reduced, and intelligent full-automatic tooth brushing is easy to implement.

Description

technical field [0001] The invention relates to a toothbrush, in particular to an all-round scientific toothbrush. Background technique [0002] One of the basic behaviors of healthy life guarantee is to clean teeth. In daily life, people usually use toothbrushes to clean teeth. Therefore, toothbrush is requisite personal cleaning utensil in people's daily life, and toothbrush is used to scrub the dirt on tooth surface by cooperating with toothpaste, thereby reaches the purpose of cleaning teeth. [0003] At present, there are two main types of toothbrushes commonly used in the market: manual toothbrushes and electric toothbrushes. [0004] A common manual toothbrush is composed of toothbrush bristles and a toothbrush handle, and the toothbrush bristles are simply fixed at one end of the toothbrush handle. Though this manual toothbrush is simple in structure, convenient and practical, affordable, its shortcoming is also obvious, mainly shows in: because the area of ​​brist...

AI Technical Summary

Problems solved by technology

Although electric toothbrushes are superior to manual toothbrushes, these electric toothbrushes still cannot fully guarantee the correctness of brushing actions and the comprehensiveness of brushing teeth. Unable to be promoted on a large scale in the market

[0006] The common problem of the above two types of toothbrushes is that the brush head of the toothbrush is always very small, and the shape of the brush head of the toothbrush cannot guarantee that it can brush every place of the teeth, such as the root of wisdom teeth and the gap between teeth Therefore, the user needs to manually move the toothbrush frequently to perform positioning to complete brushing; at the same time, the steps of applying toothpaste, brushing, and cleaning in the process of brushing cannot be automatically completed, resulting in time-consuming and laborious brushing. Cleanliness cannot be guaranteed

[0007] When brushing teeth daily, although most people know that the correct and scientific brushing direction is to brush the head of the toothbrush vertically from the root to the tip of the tooth, but due to various considerations, such as cleaning concepts, brushing habits, time constraints, etc. As a result, most toothbrush users are impossible or unwilling to spend too much energy and time to strictly follow the correct and scientific brushing direction every time they brush their teeth, and this correct and scientific The brushing action is not something that can be done naturally and correctly by the human body structure and human mechanics. Therefore, many people brush their teeth more casually in their daily life, especially when brushing their teeth, it is easier to ignore the cleaning of the occlusal surface of the teeth. The oral cleaning effect obtained is not ideal, and even the wrong brushing action may damage the gums, cause more oral diseases, and endanger health

In particular, since the occlusal surface of the teeth is just uneven, more and more food residues are easy to accumulate on the uneven occlusal surface of the teeth, which greatly increases the incidence of dental caries and ultimately damages human health
