By arranging the power supply portion 9 and the switch 71 near the grip portion 7, wiring is facilitated, so that the overall structure of the cleaning apparatus 100 is compact.

The cleaning principle of the cleaning device 100 is: the pump body 15 extracts the cleaning liquid in the supply tank 3, flows to the surface to be cleaned through the third channel 141 and the first channel 21, forms dirt with dust and the like, the driving part 5 works, the impeller 62 generates air flow, the dirt is sucked into the second channel 22 from the second opening 24, the dirt enters the recovery tank 4 through the fourth channel 142, the dirt is subjected to water-gas separation under the centrifugal action of the separating part 63, the separated dirt enters the recovery tank 4, the clean air flow enters the driving part 5 through the support frame 11 and the impeller 62, and finally flows out through the air outlet 121, and the cleaning work is completed.

To sum up, be provided with the sealing member that is used for forming seal structure between cleaning equipment's separator and mounting bracket, cleaning equipment during operation, the impeller rotates in order to produce the air current, the sealing member upwards moves under the effect of air current in order to form airflow channel between mounting bracket and separator, when cleaning equipment stop work, the sealing member forms seal structure in order to be sealed with aqueous vapor separation subassembly, thereby isolated driving piece that is located aqueous vapor separation subassembly top and the collection box that is located aqueous vapor separation subassembly below, thereby prevent that the sewage that is located the collection box from entering into in the driving piece, improve cleaning equipment's life and user experience.

The above is only one embodiment of the present invention, and any other modifications based on the concept of the present invention are considered as the protection scope of the present invention.
