Problems solved by technology

[0020] However, for example, for the electric toothbrush described in Patent Document 1 that stores two toothbrush bodies together with the operating portion in a box, the toothbrush body must be installed on the drive shaft of the operating portion when it must be used, and the drive shaft will be driven from the drive shaft when not in use. Take off the toothbrush body, which will cause cumbersome assembly and disassembly operations
And, in the toilet etc. of limited narrow space like the work unit, during the period of brushing teeth, also produce such problem: worry about the placement place of the box that accommodates another toothbrush body
However, if only the neck is shortened, in order to reach the inner teeth, it is necessary to put it in the mouth until the rough operation part, and the operability is impaired.
In addition, in order to shorten the operating part, if the battery is made into a battery equivalent to a button battery, there will be problems such as insufficient motor torque, frequent battery replacement, or frequent charging.

Abstract

Provided is an economical electric toothbrush that can reliably vibrate a head part while ensuring teeth-cleaning operability in the mouth, and in which a smaller size and lighter weight are achieved, and portability is improved. This electric toothbrush (10) comprises a head part (13), a neck part (12), and an operating part (11), wherein the head part (13) has a coin-shaped vibrating motor (17) on the bottom surface side of the head part, and a detachable brush plate (22) on the upper surface side of the head part; a battery and switch part are stored in the operating part (11); and the toothbrush is vibrated by the vibrating motor that is operated by electricity supplied from the battery.

Description

technical field [0001] The present invention relates to an electric toothbrush excellent in portability. [0002] This application claims priority based on Japanese Patent Application No. 2012-068043 for which it applied in Japan on March 23, 2012, and uses the content here. Background technique [0003] In recent years, not only in the home, but also in places such as workplaces or places of travel, there are many cases where teeth are brushed. Therefore, portability is required for the toothbrush, but in the case of an electric toothbrush, the problem of poor portability arises due to the overall size increase. [0004] As electric toothbrushes, there are known a rotary type in which a head with a plurality of brushes is attached and rotates, and a vibration type in which a head with a plurality of brushes is attached and vibrates. The vibration type uses the eccentric hammer on the output shaft of the motor to vibrate the whole brush. Since there are fewer structural pa...
