Abstract

The utility model relates to a rotating toothbrush. The front end of a rotating rod of the utility model is provided with worm which is engaged with a worm wheel brush hair body. The worm wheel brush hair body rotates in the direction perpendicular to the worm. The upright brushing along the tooth slots can be done in use, and the rotation direction of brush hair is not needed to be changed no matter which part of the tooth is brushed. The utility model has convenient usage, and is favorable for the sanitation of teeth.

Description

T-like rotating toothbrush

The utility model belongs to daily living article.

The toothbrush of general domestic use all is a hand, only is suitable for reciprocal Dragsaw type and brushes teeth, and this method for brushing teeth science not very, and the clean tooth of brush not only, and damage gum easily.The method for brushing teeth of science should be perpendicular brush, and promptly bristle rotates to crown portion from gums along slot.In order to adapt to this requirement, electronic rotary toothbrush has abroad appearred, it is the axial rotation along handle as clear 59-40807, therefore in use must be according to different situations Push switch at any time, the rotation direction of conversion bristle, otherwise may produce by the phenomenon of crown to the anti-brush of gums, gum stabbed, and rotating speed is too fast, uses inconvenience.

The purpose of this utility model provides and does not need conversion rotation direction De Xia font rotary tooth brush in a kind of use.

The purpose of this utility model is finished as follows: the thorny arbor of micro motor for driving worm screw that with the battery is power supply is to rotation, and bristle is installed on the worm gear, driven by worm screw, worm gear body brush pivot center vertical handle axis, during use, which part of the tooth of no matter brushing teeth all need not to change direction of rotation, easy to use, simple in structure.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
