Referring to fig. 7, the water supply assembly 300 includes a clean water tank 310, a water supply pipeline 320, a water pump 330 and a water dividing member 340, wherein the clean water tank 310 is detachably mounted on the machine body 200, the water dividing member 340 is disposed at the front side of the floor brush main body 130 and is located at the rear of the roller brush cavity 150, a plurality of water outlet holes 341 distributed at intervals along the left-right direction are formed in the front wall of the water dividing member 340, one end of the water supply pipeline 320 is detachably in butt joint with the clean water tank 310, the other end of the water supply pipeline 320 is in butt joint communication with the water inlet holes of the water dividing member 340, and the water pump 330 is disposed on the water supply pipeline 320. The liquid in the clean water tank 310 can flow to the water dividing member 340 through the liquid supply pipe 320 by pumping the water pump 330, and the liquid flowing into the water dividing member 340 flows out from the water outlet 341 and is absorbed by the cleaning member 110, so that the cleaning member 110 can absorb and wet. It is to be understood that the specific structure of the water diversion member 340 may refer to the prior art, and will not be described herein.

Referring to fig. 6, in order to improve cleaning effect, a scraper 160 is provided at the front side of the floor brush main body 130 at the bottom of the water diversion member 340 and above the soil suction port 120, and the front end of the scraper 160 extends into the roller brush cavity 150 and is in interference contact with the cleaning member 110. In operation of the device, the scraper 160 scrapes the rotating cleaning member 110, and dirt scraped off by the cleaning member 110 by the scraper 160 falls down to the dirt suction port 120. The front side of the floor brush body 130 is also provided with a floor scraper 170 below the dirt suction opening 120, the floor scraper 170 has elasticity and the bottom side is in interference contact with the surface to be cleaned. When the floor brush 100 moves, the floor wiper 170 wipes the surface to be cleaned and dirt is accumulated at the dirt suction port 120.

Referring to fig. 8, when the main body 200 is rotated forward to the front limit position in the upright state, the main body 200 is substantially perpendicular to the surface to be cleaned, and when the main body 200 is rotated backward to the rear limit position in the upright state, an included angle α1 is formed between the main body and the surface to be cleaned, and the included angle α1 can be set to be 60 °, 55 °, 50 °, 45 °, 40 ° or the like. Referring to fig. 4, at this time, the triggering portion 511 of the baffle 510 is not stressed, the depth of the shielding portion 512 extending into the sewage containing cavity 423 is smaller, a certain gap is formed between the shielding portion 512 and the positioning plate 4211, the gap between the left and right sides of the positioning plate 4211 and the inner wall of the sewage containing cavity 423 jointly form a ventilation area between the sewage containing cavity 423 and the ventilation opening 425, the ventilation area of the ventilation area is larger, the suction strength of the sewage collecting airflow formed by the suction provided by the sewage collecting fan 410 is also stronger, and the sewage at the sewage sucking port 120 can smoothly flow into the sewage containing cavity 423 of the sewage barrel 420 from the sewage inlet 424 under the action of the strong sewage collecting airflow due to the larger height difference between the sewage sucking port 120 and the sewage inlet 424. Even if a very small portion of the dirty liquid splashes into the vents 425, the kinetic energy of the dirty liquid is depleted during the ascent and does not flow into the dirty fan 410.

Referring to fig. 9, when the body 200 is in the lying state, the roller 530 contacts the surface to be cleaned and forces the trigger portion 511 to drive the shielding portion 512 to move toward the body 200 to abut against the positioning plate 4211, at this time, an included angle α2 is formed between the body 200 and the surface to be cleaned, and the included angle α2 may be set to be 0 °,3 °,5 °, 7 °,10 °,12 °,15 °,17 °,20 ° or other reasonable dimensions. The handle 600 can be kept upright when the body 200 is in a reclined state, facilitating the user's handling of the device through the handle 600. When the machine body 200 is in a lying state, the baffle 510 is in the position shown in fig. 5, at this time, the depth of the shielding part 512 extending into the sewage containing cavity 423 is large and is in contact with the positioning plate 4211, the gap between the left and right ends of the positioning plate 4211 and the inner wall of the sewage barrel 420 forms a ventilation area between the sewage containing cavity 423 and the ventilation opening 425, at this time, the ventilation area is small, the strength of the sewage collecting airflow formed by the suction provided by the sewage collecting fan 410 is reduced, and because the height difference between the sewage sucking opening 120 and the sewage inlet 424 is greatly reduced, the sewage at the sewage sucking opening 120 still can smoothly flow into the sewage containing cavity 423 of the sewage barrel 420 from the sewage inlet 424 under the action of the sewage collecting airflow with the reduced strength, and the splashing range of the sewage flowing into the sewage barrel 420 from the sewage inlet 424 is reduced, so that the sewage can be prevented from splashing into the 425 and flowing to the sewage collecting fan 410 along with the airflow. As another solution of this embodiment, the body 200 may also tilt forward by a certain angle with respect to the vertical direction when rotating forward to the front limit position in the upright state, improving the stability of the body 200 when the device is in the stationary state.

As another solution of this embodiment, the main body 200 may be a structure that is divided up and down and pivoted together, and at this time, the sewage tank 420 is preferably detachably mounted on the rear side of the lower main body, and the sewage collecting fan 410 is preferably disposed on the upper main body.

Alternatively to this embodiment, the fresh water tank 310 may be detachably installed at the rear side of the main body 200 above the foul water tank 420, or may be detachably installed at the front side of the main body 200.

As another alternative of the present embodiment, the rear roller 530 of the shielding part 512 may be provided, and the roller 530 may be provided at the rear side of the sewage bucket 420 or the rear side of the main body 200.
