[0029] The vacuum motor 4000 is located at the bottom of the machine body 1000 and close to the ground brush 3000, adopts a series-excited alternating current motor, and can also adopt a direct current motor. The motor axis of the vacuum motor 4000 is parallel to the horizontal plane and parallel to the left-right direction of the ground brush 3000.

[0030] In combination with Figures 2-6 The utility model also provides a second embodiment of a sewage recovery device, which comprises a box 2200 with a box cavity 2210, a box cover 2400 arranged above the box 2200 and sealing the open end of the box cavity 2210, a float 2600 accommodated in the box cavity 2210, and an air outlet pipe sealing ring 2800 arranged on the top of the air outlet pipe 2240 and sealing the output end of the transition cavity 2446.

[0031] The box 2200 comprises a dirty liquid inlet pipe 2220 and an air outlet pipe 2240 arranged in parallel with the dirty liquid inlet pipe 2220; wherein the top end of the dirty liquid inlet pipe 2220 is lower than the top end of the air outlet pipe 2240, and the bottom end of the dirty liquid inlet pipe 2220 and the bottom end of the air outlet pipe 2240 are in the same plane.

[0032] The box cover 2400 comprises an upper box cover 2420, a lower box cover 2440, a baffle 2444 arranged at least partially around the dirty liquid inlet pipe 2220 and on the lower box cover 2440, an air inlet 2445 arranged above the baffle 2444 and on the lower box cover 2440, a transition cavity 2446 arranged above the baffle 2444 and between the upper box cover 2420 and the lower box cover 2440, and a float 2600 closing or opening the input end of the transition cavity 2446, and the output end of the transition cavity 2446 is in communication with the air outlet pipe 2240.

[0033] The float 2600 comprises a float part 2620 arranged at least partially around the dirty liquid inlet pipe 2220, and a float part back plate 2640 arranged on the float part 2620 and capable of closing the input end of the transition cavity 2446, wherein the float part 2620 comprises a pair of float part arms arranged on both sides of the float part back plate 2640, and the dirty liquid inlet pipe 2220 is arranged between the two float part arms.

[0034] In operation, dirty liquid from the ground enters the liquid recovery channel of the floor brush 3000, is transported upwards through the dirty liquid inlet pipe inlet 2222 at the bottom and the dirty liquid inlet pipe outlet 2224, and then enters the box cavity 2210. Since the baffle 2444 is arranged around the dirty liquid inlet pipe outlet 2224, the dirty liquid is blocked from moving downwards, and then the airflow moves upwards into the air inlet 2445, and then into the transition cavity 2446, and then into the air outlet pipe inlet 2242 at the downstream end of the transition cavity 2446, and moves downwards through the air outlet pipe outlet 2244 to flow out of the dirty liquid recovery device 2000, and then into the vacuum motor 4000, and finally discharged to the atmosphere. Once the dirty liquid exceeds a certain value, the float 2600 moves upwards, so that the float part back plate 2640 blocks the air inlet 2445, so that the vacuum motor 4000 stops rotating, and also prevents liquid from entering the air inlet 2445.

[0035] The dirty liquid inlet pipe and the air outlet pipe are arranged in parallel, the dirty liquid inlet and air outlet structure is simple, the entry of water vapor is reduced, and the working reliability is ensured.
