There is motor cavity 1300 in motor part 1200.

[0027] Sewage tank 2000 is used to separate water and gas of recovered dirty liquid, and liquid is kept in it, and gas enters motor assembly 4000 through air outlet pipe 2200. Air outlet pipe 2200 is communicated with air outlet hole 1140.

[0028] The floor brush 3000 uses a water-absorbing double rotating roller brush body to clean the dirt on the horizontal surface and recycle the dirt on the horizontal surface into the sewage tank 2000.

[0029] At least two motor air ducts are arranged between the motor assembly 4000 and the vertical body 1000, wherein the input and output ends of the first motor air duct are both located on the support part 1100, while the output end of the second motor air duct is located on the motor part 1200, and the input end of the second motor air duct is located at the support part air inlet hole on the support part 1100. The motor assembly 4000 includes a motor shaft 4020, an impeller 4200 driven by the motor shaft 4020, a cooling fan 4600 driven by the motor shaft 4020, a first air inlet 4120 connected to a first motor air duct, an air inlet duct 4140 having one end connected to the air inlet 4120, a stator 4400 located between the impeller 4200 and the cooling fan 4600, a first air outlet 4160 located downstream of the first air inlet 4120, a second air inlet 4180 adjacent to and isolated from the first air outlet 4160, and a second air outlet 4190 located downstream of the second air inlet 4180. The first motor air duct is connected to the impeller 4200, while the second motor air duct is connected to the cooling fan 4600. The motor assembly 4000 also includes an axial inlet 4142 at the other end of the air inlet duct 4140, which is coaxial with the motor shaft 4020. The motor shaft 4020 is perpendicular to the direction of movement of the floor brush 3000 and parallel to the horizontal plane. The motor assembly 4000 also includes a first air outlet end 4220 connected to the second air outlet 4190 and the first motor air duct, and a second air outlet end 4240 connected to the first air outlet 4160 and the second motor air duct.

The dirty liquid then enters the liquid recovery channel of the floor brush 3000 from the horizontal surface, and then flows into the sewage tank 2000 for water and gas separation. The air flow then passes through the outlet pipe 2200 into the first motor air duct of the motor assembly 4000, flows in from the first air inlet 4160, then flows out from the first air outlet end 4220, passes through the air outlet channel 1340, and is finally discharged into the atmosphere through the air outlet hole 1160 of the support part. At the same time, in order to ensure the heat dissipation of the motor assembly 4000, the second motor air duct of the motor assembly 4000 enters the heat dissipation airflow from the air inlet of the support part, enters along the second air inlet 4180, and then flows out through the second air outlet 4190, and then is discharged to the atmosphere through the motor air outlet channel 1240. Therefore, the first motor air duct discharges wet airflow, and the second motor air duct discharges dry airflow, realizing the separation of dry and wet airflow, avoiding wet airflow from entering the motor, and ensuring the reliability of the motor.
