Abstract:
A multifunctional brush head (30) and a multifunctional electric toothbrush. The multifunctional brush head (30) comprises a bristle plate (31), a mounting base (32), a main rotating shaft (33), a rotating member (34), a stretching shaft (35), and a water-resisting layer (36); one end of the bristle plate (31) is provided in an inner cavity of the mounting base (32) and rotatably connected to the bottom of the mounting base (32) by means of the main rotating shaft (33); the rotating member (34) is provided on the side of the bristle plate (31) close to the mounting base (32) and connected to the stretching shaft (35); the water-resisting layer (36) is provided in a gap between the bristle plate (31) and the mounting base (32); and the rotating member (34) is used for driving the bristle plate (31) to reciprocatingly rotate around the main rotating shaft (33) clockwise or anticlockwise under the stretching of the stretching shaft (35). In this way, the problems that when an existing electric toothbrush is used for cleaning teeth, a brush head can only clean the teeth in one direction, a brush handle needs to be continuously rotated, and when different parts of the teeth are cleaned, the brush handle needs to be continuously pushed and pulled, causing poor use experience are solved.
