The second motor 14 is connected to the second fan blade and fixed in the second vacuum chamber 13. The bottom of the second vacuum chamber 13 has an inlet pipe connected to the second air inlet 12 on the base 1. The second vacuum chamber 13 is connected to the hot air interface 11 through a warm air duct 16. An electric heating component 17 is arranged in the warm air duct 16. A contact switch is arranged in the hot air interface 11 to cooperate with the external pipe to control the electric heating component 17 to realize the heating function. The air enters from the second air inlet 12 at the bottom, and is discharged from the hot air interface 11 after the temperature is increased by the electric heating component 17. A water pump 30 is provided next to the second vacuum chamber 13. The inlet of the water pump 30 is connected to the water outlet of the clean water tank 28 through a water pipe. A control valve is usually provided at the water outlet, and the outlet of the water pump 30 is connected to the water outlet hole 36 on the first air inlet 6 of the cleaning device through a water pipe.

[0036] Of course, the entire cleaning device also has an electronic control system and a corresponding circuit board, which is a conventional design in the electronic field to control the operation of the first motor, the second motor, the water pump, and the electric heating component.

[0037] When the user needs to use the machine for washing, the user needs to place the machine next to the expected location, connect the power cord, and then use the connecting pipe with the dirt suction head to connect to the first air inlet 6 of the cleaning device. At the same time, the connecting pipe with the dirt suction head itself has a water pipe, which is connected to the water outlet 36 on the first air inlet 6 of the cleaning device. Start the water pump 30, pump the water from the clean water tank 28 to the water outlet 36, and then transport it to the vacuum head through the water pipe of the connecting pipe itself, so that it can be flushed out to wash the bottom surface or carpets and other items.

[0038] When the user uses this machine to suck sewage, the user needs to place the machine next to the expected location, connect the power lines, and then use a connecting pipe with a sewage suction head to connect to the first air inlet 6 of the cleaning device. The user can use the sewage suction head to suck the waste water into the L-shaped air duct 27, and then enter the dust cup and sewage tank assembly 9 first, and pass through the separation mechanism and filter structure 34 in the dust cup to retain the waste, dust and hair in the upper dust cup 21, and discharge the waste water into the sewage tank 22 below. The treated relatively clean air is then discharged after passing through the first vacuum chamber 3 and discharged through the exhaust port on the base 1.

[0039] When the user needs to use the electric heating component 17 for drying, the user only needs to connect the blowing pipe with the hot air interface 11, and cooperate with the contact switch and the blowing pipe to make the second motor 14 and the thermal component 17 start working, and draw air in from the second air inlet 12, pass through the second motor 14 and the second fan blade 15, and enter the warm air duct 16. The electric heating component 17 in the warm air duct 16 heats the air, and then discharges it into the blowing pipe from the hot air interface 11 of the base 1, and finally directs the hot air to the place that needs to be dried.
