Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to a waterproof structure for the charging port of an electric toothbrush. Background Technique

[0002] An electric toothbrush is composed of a motor, a brush head and a power supply. Through the rapid rotation or vibration of the motor core, the brush head generates high-frequency vibration, decomposes toothpaste into fine foam to clean the tooth gaps, and often charges the power supply through the charging port body. Since the electric toothbrush often contacts water, in order to ensure the normal use of the charging port body, a waterproof structure is often set at the charging port body to protect it.

[0003] The existing waterproof structure is often a waterproof gasket, which is squeezed at the charging port body to seal the charging port body. Due to the frequency of charging, the waterproof gasket is disassembled and installed many times, which easily causes wear and does not fit well with the charging port body, and then easily allows water to enter the charging port body, affecting normal charging and bringing inconvenience to people's use. Therefore, a waterproof structure for the charging port of an electric toothbrush is specifically proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof structure for the charging port of an electric toothbrush, which has the advantage of good waterproof effect.
