Abstract

The invention discloses an off-axis electric toothbrush capable of automatically realizing a 'pasteurization' tooth brushing method and a use method thereof, so that a brush head completely abandons vibration and rotation, and teeth are cleaned by purely reciprocating along a slit between teeth. The toothbrush specifically comprises a handle body, a driving mechanism arranged in the handle body and a brush head arranged at the output end of the driving mechanism and capable of swinging in a reciprocating manner or moving in a linear reciprocating manner in a direction parallel to the tooth gaps. The driving mechanism drives the brush head to perform reciprocating cleaning work along the tooth gaps.

Description

Babbitt electric toothbrush and using method thereof

Technical Field

The invention relates to an oral cleaning appliance, in particular to an electric toothbrush capable of automatically realizing a 'pasteurization tooth brushing method' and a use method thereof.

Background

With the improvement of life quality, people pay more and more attention to the health care of teeth. In recent years, electric toothbrushes have been selected by an increasing number of people. Electric toothbrushes currently on the market are of many brands, but work mainly in two categories. Firstly, a toothbrush with a rotary brush head; one type is the so-called "sonic" toothbrush.

The brush head of the toothbrush with the rotary brush head circularly moves parallel to the tooth surface, so that gaps between teeth are difficult to brush, and gaps between tooth roots and gums cannot be brushed; moreover, the rotating brush head can 'sweep' the tooth root and the tooth end, which is exactly the mistake that needs to be avoided during tooth brushing; the market space for "rotary" brush head toothbrushes will be smaller and smaller.

The so-called "sonic" of a "sonic" toothbrush is not high frequency vibrations. The toothbrush has better effect than a toothbrush with a rotary brush head, and can not sweep the tooth surface transversely; however, there are two major disadvantages: firstly, the place between the tooth root and the gum which is most easy to store dirt and dirt is the 'blind spot' of the sonic toothbrush; secondly, the brush head can do bouncing type vibration on the tooth surface, which can cause damage to the teeth of people with bad teeth, such as old people, children and people with various periodontal diseases, and the acoustic wave toothbrush has poor adaptability.
