Abstract

Disclosed is an electric toothbrush capable of applying large vibration to the brush by small vibrations of a vibration source. An electric toothbrush (100) is provided with a tubular casing (20) and a vibrating body (30) that applies vibration to a brush (42), one end of which is positioned in the interior of the casing (20), while the other end thereof is arranged so as to project to outside the casing from an aperture (20a) at the tip of the casing, the brush (42) being positioned in the vicinity of this other end. A vibration source (10) is arranged at one end of the vibrating body (30), and the outer peripheral surface of the vibrating body (30) is supported in a position that is more offset towards the vibration source (10) than the centre of this vibrating body (30) in the longitudinal direction thereof.

Description

technical field [0001] The present invention relates to electric toothbrushes. Background technique [0002] Conventionally, an electric toothbrush is known in which a vibration source is provided inside a toothbrush main body to transmit vibration to bristles (see Patent Documents 1 and 2). In such an electric toothbrush, in order to efficiently vibrate the bristles, for example, a technique of improving vibration transmission efficiency or generating resonance is used. [0003] However, these techniques tend to complicate the mechanism for transmitting vibrations or make it difficult to downsize the vicinity of the bristle portion. Therefore, it is desirable to have a technology that makes the vibration of the vibration source small and vibrates the bristles greatly. [0004] Patent Document 1: JP Utility Model Registration No. 3008856 Gazette; [0005] Patent Document 2: JP-A-10-192054. Contents of the invention [0006] The problem to be solved by the invention ...
