Description

Electronic rotary toothbrush

Technical field

This utility model relates to a kind of toothbrush, particularly a kind of electronic rotary toothbrush.

Background technology

Existing manual toothbrush uses very effort, is difficult to the slit of outwash tooth.Especially old man and child are difficult to use.Electric toothbrush is also arranged at present, but its complex structure, and brush is hindered the position of the non-tooth of gingiva and oral cavity easily; And do not have to regulate the function that rotates and reverse, use very inconvenient.

Summary of the invention

The purpose of this utility model just provides a kind of electronic rotary toothbrush, and to solve the complex structure that existing electric toothbrush exists, brush is hindered the position of the non-tooth of gingiva and oral cavity easily; And do not have to regulate the function that rotates and reverse, use very inconvenient problem.

The technical solution of the utility model is: comprise brush and brush holder, it is characterized in that: motor, rotating shaft and battery are arranged in brush holder, motor and battery are installed in the cavity of brush holder, and battery is positioned at the rear portion of brush holder, and its two poles of the earth are connected with two power ends of motor respectively by permutator; The coaxial connection of axle of described rotating shaft one end and motor, this rotating shaft other end extends to described brush, this brush is connected with radial bristles at the side face of rotating shaft, the outer end of this bristle is cylindrical profile, be provided with wool brushing cover at this bristle, the side face of this wool brushing cover leaves bristle mouth vertically, exposes bristle at this bristle mouth.

Between described motor shaft and rotating shaft, be provided with reducing gear.

Described permutator is provided with three gears, is respectively just to change, turn-off and reverse.

The utility model has the advantages that simple in structurely, be not easy to brush the position of hindering the non-tooth of gingiva and oral cavity, and have the function that adjusting is just changeed, reversed and stops, using easily.
