The design mode enables the positions between the clean water tank, the sewage tank, the power supply part and the air suction motor to be more compact, the height of the machine body can be reduced, and meanwhile the capacity of the clean water tank and the capacity of the sewage tank can be guaranteed.

Further, a fluid pipe 33 (i.e., a pipe in which dirty air and sewage are mixed) is provided at the rear side of the sewage tank 10, and includes a pipe inlet 34 and a pipe outlet 35. The pipeline inlet is located on the bottom end surface of the body 30 and at the rear end of the support plate 32 of the waste water tank 10, and the pipeline outlet 35 is located on the side wall surface 36 of the accommodating chamber 34. The fluid pipe 33 is not provided in the sewage tank 10, so that the volume of the sewage tank is increased, and the diameter of the sewage tank may be relatively large, thereby not easily causing clogging.

A clean water line (not shown) is connected between the clean water tank 50 and the brush body 40, and the clean water tank 50 sprays liquid onto the surface of the roll brush in the brush body 40 through the clean water line and a water spray assembly (not shown), wherein the clean water line and the fluid line 33 are both disposed inside the same casing (not shown) for easy installation and maintenance.

Clear water pipeline and fluid pipeline are drawn together to the intraductal casing of setting at the fuselage, and the casing chamber can hold the sleeve pipe and protective case produces the aversion because of vibration etc. and takes place to damage.

The sewage tank 10 is detachably disposed in the accommodating chamber 34, and an upper fluid outlet of the sewage tank 10 corresponds to an air inlet of the suction motor. A fluid inlet 210 communicated with the pipe outlet 35 is formed at the rear surface of the wastewater tank, and the fluid discharged through the pipe outlet 35 enters the interior of the wastewater tank through the fluid inlet 210. Preferably, the pipeline outlet 35 corresponds to the position of the fluid inlet 210, and the extension line of the orientation of the pipeline outlet 35 is approximately tangent to the inner wall surface of the fluid inlet 210, so that the entering gas can generate the cyclone separation effect.

The wastewater tank 10 includes an upper tank 100, a lower tank 200, and a fluid guide assembly 300, and the upper tank 100 and the lower tank 200 are separable in an up-down direction.

The floating assembly 500 is disposed in the lower case 200, and the floating assembly 500 includes a floating member 510 and a support frame 520. One end of the support frame 520 is connected to the bottom end 120 of the upper case 100, the other end of the support frame 520 extends to the inside of the lower case 200, the inside of the support frame 520 forms an upper chamber, and the floating member 510 is located inside the upper chamber. An air hole 521 is formed in the outer wall surface of the support frame 520, wherein the air hole 521 is located on the region of the support frame 520 except the rear surface.

When performing a cleaning work, for example, the brush body 40 of the floor cleaning device 1 is used to suck floor sewage, which is introduced from the floor through a pipe into the fluid inlet 210 of the sewage tank 10, the fluid comes into contact with the fluid guide member 300 at a front position thereof, and the fluid guide member 300 forms a barrier against the fluid, so that the fluid is rapidly guided to a bottom position of the lower tank 200. The gas enters the upper case 100 through the gas holes 521 of the support frame 520, passes through the filter assembly 400, and is discharged through the gas outlet 110. The floating member 510 may float up and down in the support frame 520, and when the water level reaches a certain level, the floating member 510 floats up to close the air inlet of the suction motor, thereby preventing fluid from entering the motor cavity and damaging the motor. The sewage tank in other embodiments of the present invention may further include a liquid detection part for detecting liquid in the sewage tank. The detection part can adopt a liquid level detection sensor arranged inside or outside the sewage tank or a weight sensor arranged on a supporting plate of the sewage tank and used for detecting the whole weight of the sewage tank.

When the weight detection sensor is selected as the liquid detection part, if the weight detection sensor detects that the current weight of the sewage tank reaches the maximum weight, the weight signal is generated and then sent to the controller of the cleaning equipment, and the controller controls the air suction motor to stop working.

The longitudinal plates 310 and the transverse plates 320 are connected to each other, and the width of the longitudinal plates 310 is not smaller than the width of the fluid inlet 210, thereby better guiding the fluid. The longitudinal plate 310 is positioned between the inner sidewall of the lower tank 200 and the floating assembly 500, and it can be said that the longitudinal plate 310 is disposed between the fluid inlet 210 of the lower tank 200 and the support frame 520. The upper end of the longitudinal plate 310 is connected to the bottom end 120 of the upper tank 100, and the lower end of the longitudinal plate 310, on the side facing away from the fluid inlet 210, is connected to the lateral plate 320. Preferably, the longitudinal plate 310 is an inclined plate-shaped member, that is, a lower portion of the longitudinal plate 310 is spaced apart from an inner sidewall of the lower case 200 by a distance greater than an upper portion of the longitudinal plate 310 is spaced apart from the inner sidewall of the lower case 200. So that the longitudinal plates 310 guide the fluid without causing resistance to the fluid entering the lower tank 200, that is, the lower portions of the longitudinal plates 310 are located farther from the inner sidewall of the lower tank 200, facilitating the fluid to be quickly introduced into the bottom of the lower tank 200 without significantly increasing the volume of the cleaning apparatus.

Further, the wall surface of the side of the longitudinal plate 310 facing the fluid inlet 210 is of a smooth structure, so that dirt in the fluid is prevented from adhering to the wall surface. The lower end 311 of the longitudinal plate 310 extends towards the bottom of the lower tank 200 and beyond the connection of the float member to the support frame, avoiding fluid contact with the float assembly 500 during the fall to the bottom of the lower tank.

The transverse plate 320 of the fluid guide assembly 300 is connected at one end to the side of the longitudinal plate 310 facing the floating assembly and at the other end to the outer wall surface of the support frame 520, thereby improving the strength of the longitudinal plate 310 when it is in contact with the fluid.

Preferably, a handle 220 may be further provided on an outer sidewall of the lower housing 200 to facilitate removal of the wastewater tank from the floor cleaning device.

According to the embodiment of the utility model, the fluid inlet is positioned on the side wall of the sewage tank and corresponds to the fluid guide component, when the fluid contacts with the fluid guide component, the fluid can form a block, so that the fluid is quickly guided to the bottom position of the lower tank body; the fluid guide plate is an inclined plate body, and the distance from the lower end part to the side wall of the lower box body is greater than the distance from the upper end part to the side wall of the lower box body; the wall surface of the fluid guide plate facing the fluid inlet is smooth, so that dirt in the fluid is prevented from adhering to the wall surface.
