Description

Technical Field

[0001] The utility model relates to the field of pool cleaning, in particular to a pool cleaning machine. Background Art

[0002] In the current pool cleaning equipment market, pool cleaning machines, as an efficient and convenient cleaning tool, have been widely used. However, for existing pool cleaning machines with a motor and a battery, the motor and the battery are often separately waterproof sealed. This design method not only increases the manufacturing complexity and cost of the product, but also significantly increases the number of seal tests of the product, resulting in low production efficiency. More importantly, the separate sealing design increases the risk of water leakage, posing a potential threat to the stability and service life of the equipment.

[0003] Specifically, since the motor and the battery are separately sealed, multiple seal tests and verifications are required respectively, which not only prolongs the production cycle, but also increases the probability of test failure. In addition, since there may be joints or interfaces between the two independent sealing systems, these areas often become weak links for water leakage, further increasing the risk of water leakage.
