[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] The utility model is provided with a water tank, a water pump, a delivery hose, a hollow plate, a spray port, a sponge and an electric telescopic rod. When cleaning is needed, the water pump is started, and the working water pump draws clean water from the water tank and delivers it to the hollow plate through the delivery hose. The clean water delivered to the hollow plate is sprayed out through the spray port to evenly spray the inside of the device. Afterwards, the electric telescopic rod is started, and the working electric telescopic rod can drive the hollow plate to move downward, so that the sponge can wipe the inside of the device body. Manual cleaning is not required, and the cyclone device does not need to be opened during cleaning, which is more convenient.
[0019] The utility model is provided with water inlets, and two water inlets are tangentially inserted into the device body, and water is symmetrically introduced through a bidirectional gradient, which, on the one hand, increases the processing capacity and prevents the precipitation of suspended matter during the water intake process, and on the other hand, can stabilize the flow state and enhance the anti-disturbance capability.
