Description
Technical field
This utility model relates to a kind of tow-head electric toothbrush, belongs to sphere of life.
Background technology
A variety of toothbrush is had in life, but be all that design is irrational, also be unscientific when most people is brushed teeth, according to the structure of tooth and gingiva, brush only can make bacterial heap in the gap that teeth roots and tooth and gingiva are formed up and down, and such brush is not only brushed unclean, and brush dirtier and dirtier, also can scratch dental surface, severe patient causes periodontitis, and obvious ordinary toothbrush practicality is not strong.
Summary of the invention
The purpose of this utility model is the tow-head electric toothbrush providing a kind of high-efficient cleaning except antibacterial between tooth.
technical solution
This utility model comprises: housing, motor, brush, slide block, it is characterized in that, motor is provided with in housing, motor output shaft is connected with first group of worm and gear, the worm screw of the worm gear of first group of worm and gear and second group of worm and gear and connecting rod are arranged on bent axle respectively, crankshaft two end is fixed on housing, worm gear on second group of worm and gear is provided with minor axis, minor axis is connected with wide gear, wide gear and narrow gears meshing, narrow gear is connected with the first reverse wheel by major axis, and reverse wheel is connected with brush by major axis; Described slide block is provided with major axis and axis installing hole and break-in and takes turns mounting groove, and described slide block and rod hinge connection, axis is provided with the second reverse wheel, and the second reverse wheel is connected with brush by axis; Described major axis and the first reverse wheel, axis and the second reverse wheel are interference fit, slide block and major axis and axis matched in clearance; Described housing is provided with battery folder and switch.
Described motor and battery folder are set on the side rib plate in housing.
Described brush comprises hair brush base, bristle, and hair brush base is cylindrical, the tangent setting of outer surface of bristle and cylindrical hair brush base.
this utility model advantage
This practical tow-head electric toothbrush adopts roller bristle, coordinates bristle axial vibrations, bristle is contacted gingiva and teeth space depths with 45 degree of corner connections, along teeth space, antibacterial is brushed out tooth.Automatically 45 degree of angles are formed during roller bristle laminating tooth, this structure can not cause cut to tooth, namely can not manufacture to antibacterial and stop place, this tow-head electric toothbrush adopts motor to provide power in addition, effectively save brushing time, and cleaning effect comparatively traditional toothbrush greatly improve, fully meet the effect of getting twice the result with half the effort.
