Abstract

The utility model discloses a motor-driven rotating toothbrush. The tail section of a brush holder is provided with an electrically-operated device with variable speed, which can rotate forwards and backwards; the electrically-operated device drives brush bristles to rotate according to the needed direction and the needed velocity, which can make the deposits in tooth gaps and the scale on the surface of teeth brush out, with larger acting force in a short period of time.

Description

Motor-driven rotating toothbrush

The utility model is to a kind of improvement on the 26S Proteasome Structure and Function of traditional toothbrush.

Traditional toothbrush is the brushing apparatus that people use already all the year round.This toothbrush can only make laterally toothbrush or brush is moving longitudinally by manually-operated in the oral cavity.Its shortcoming be because of the speed of brushing too slow.Active force is less, the method for brushing teeth sometimes incorrect (correct method is that vertically brush is moving, and majority are that laterally brush is moving).Thereby the time of not only brushing teeth is longer, also is difficult for teeth crevice and dental surface outwash.With the passage of time, easily make dental surface present the incrustation of one deck thin layer, influence the health of tooth and pure white.

The purpose of this utility model is the shortcoming at existing toothbrush, studies that a kind of speed is fast, active force is big, and has the rotary tooth-brush of cleaning function more greatly with water.

Accompanying drawing is a structural representation of the present utility model.

Substance of the present utility model is that the afterbody at brush holder is equipped with that a cover can positive and negatively rotate and the electric device of variable-ratio, rotates in order to drive bristle direction and speed as required.The specific embodiments of this design following (referring to accompanying drawing):

Battery (2), micro machine (3), change-speed gearing (4) are housed in the afterbody housing (1) of brush holder; switch (5) is equipped with on the surface of handle tail housing (1); there is one around the bristle (7) and the arc outer cover (8) that can disassemble from the handle bar at the head end of the handle bar (6) of brush holder, is not subjected to the damage of bristle in order to protection inside, oral cavity.Bristle (7) is wrapped in an end of brush holder support (9) thick and fast, and the other end of brush holder support (9) is contained in the inner chamber of brush holder handle bar (6), and meshes together the also rotatable adjustment angle of arc outer cover (8) by power transmission shaft (10) and change-speed gearing (4).

The utility model has the advantages that bristle can be both forward and reverse directions and swipe fast along the direction of teeth crevice, thus can be in the short period of time, with the incrustation thorough outwash of bigger active force with the residue in the teeth crevice and surface. Simultaneously, also can change as required the model of bristle, or by stirring out Close, make bristle carry out speed change more than two grades.

According to the needs in society and market, application of the present utility model can enlarge and extend further.For example pass through to change the physical dimension of bristle and brush holder, and the power of transmission device, as the scourer of portable bottle brushing device or the tame tool of having a meal.
