For example, household vacuum cleaners generally include a main body with a handle, a mop head, a sewage tank, a vacuum motor and other structures. The sewage tank is generally installed on the main body. When the vacuum cleaner is used to mop the floor, the water in the sewage tank will shake, and there is a possibility that water will enter the vacuum motor. Therefore, it is best to set a water gate structure between the sewage tank and the vacuum motor, which mainly plays a role in blocking water and reducing the risk of water entering the vacuum motor.
