[0002] With the development of economy and society, the popularity of electric oral cleaners is increasing. The traditional electric oral cleaner button is a switch button with a travel, and the shell needs to have a hole. During use, stains can easily enter the gap between the button and the shell, and it is easy to get dirty after long-term use. In addition, a seal is installed between the button and the shell to prevent foreign matter from entering the shell. Since the electric oral cleaner is a high-frequency appliance, after multiple presses, the seal has a certain risk of failure, resulting in an increased failure rate of the toothbrush.

[0003] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content
