CLEANING DEVICE

WIPO Patent Application WO/2023/019906

A1

A cleaning device comprises a main body (1). The main body (1) is provided with a first accommodation chamber (3) and a first electronic component (4), the first electronic component (4) being located in the first accommodating chamber (3). A first opening (6) is provided at the top of the first accommodation chamber (3). A first drainage channel inlet is provided around the top of the first accommodating chamber (3), the first drainage channel inlet being in communication with a first drainage channel (8). A first waterproof stop (2) is provided at an edge of the first opening (6), the first drainage channel inlet being adjacent to the first waterproof stop (2). The first drainage channel (8) discharges liquid around the top of the first accommodating chamber (3) through the first drainage channel inlet to the outside of the main body (1). In this way, the probability of liquid flowing into the first accommodating chamber (3) is reduced. Therefore, the first electronic component (4) is not easily immersed in liquid, reducing the risk of failure of the first electronic component (4) due to moisture caused by immersion in liquid, and increasing the service life and safety of the cleaning device.
