Description

Technical Field

[0001] The utility model relates to the field of electric suction cups, in particular to a waterproof electric suction cup. Background Art

[0002] In the construction industry, many smooth and flat plates, such as glass, marble, and ceramic tiles, often need to be transported during the construction process. Due to the large area, heavy weight, and brittle texture of the plates, how to transport them has always been a difficult problem in the industry. Therefore, electric suction cups came into being. Electric suction cups use negative pressure to suck on the plates, making transportation very convenient.

[0003] However, the electric suction cups on the market have poor overall sealing and no waterproof function. Moisture entering the electric suction cups can easily cause a short circuit in the internal circuits and affect their service life.
