Document Type and Number:
WIPO Patent Application WO/2011/132878
Kind Code:
A3
Abstract:
The present invention relates to a head of bristles for an electric toothbrush with a simple structure which is coupled to a main body of an electric toothbrush providing power so as to repeat the up and down gyration of bristles for enabling automatic brushing of the teeth, thereby improving cleaning power. To implement this, the present invention comprises: a bristles shaft in which a bristles transplanting portion is formed at one side and a shaft coupling portion is formed at the opposite side; a cylindrical shaft housing encompassing the bristles shaft; and a back cap in which an inner circumferential surface side is fixed so as to allow the bristles shaft inserted into the shaft housing to rotate and to prevent the bristles shaft from being separated and an outer circumferential surface side is coupled to the inner circumferential surface of the shaft housing and is fixed so as to prevent the bristles shaft and inserted into the shaft housing from being separated. If a power transmission shaft of an electric handle portion inserted into the shaft coupling portion of the bristles shaft gyrates, the bristles also gyrate up and down, thereby cleaning off foreign matters inserted into valleys between teeth.
