Wherein, the first port is through first inlet tube 391 and cleaning solution case 50 intercommunication, and the second port is through the end intercommunication of intaking of second inlet tube 392 and first delivery pump 31, and the third port is through the end intercommunication of intaking of third inlet tube 393 and second delivery pump 32. The first transfer pump 31 is communicated with the front water spray plate 361 through a first water outlet pipe 394, and the second transfer pump 32 is communicated with the rear water spray plate 362 through a second water outlet pipe 395. The first water inlet pipe 391 may also be directly connected to the cleaning liquid tank 50, that is, as a part of the clean water supply pipeline, connected between the three-way valve 35 and the cleaning liquid tank 50.

Clear water is sprayed on the rolling brush or the ground, sewage is generated after the rolling brush is dragged, the sewage is sucked and recovered as soon as possible, and the risk of secondary pollution to the ground caused by the sewage is reduced. In one embodiment, referring to FIG. 4, the dirt inlet of the floor brush assembly 30 includes a dirt collection port 33, a first inlet end 330, and a second inlet end 332, the dirt collection port 33 being in communication with both the first inlet end 330 and the second inlet end 332. Specifically, the dirt collection port 33 communicates with the liquid return pipe 13 through an upper opening 336 at an upper end thereof, and the dirt collection port 33 communicates with both the first inlet end 330 and the second inlet end 332 through a lower opening 338 at a lower end thereof. The first inlet end 330 is disposed facing at least a portion of the outer surface of the forward mop 341 and the second inlet end 332 is disposed facing at least a portion of the outer surface of the rearward mop 342. The dirt collecting port 33, the first inlet end 330 and the second inlet end 332 are all located between the front dragging wiping part 341 and the rear dragging wiping part 342, and under the action of negative pressure, the sewage collected by the front dragging wiping part 341 and the rear dragging wiping part 342 is sucked by the first inlet end 330 and the second inlet end 332, collected to the dirt collecting port 33, flows into the dirt collecting tank 40 through the liquid return pipeline 13, and is temporarily stored in the dirt collecting tank 40. Specifically, the first inlet end 330, the dirt collection port 33, and the second inlet end 332 are arranged in this order in the front-rear direction, and the dirt collection port 33 is located at substantially the same distance from the first inlet end 330 and the second inlet end 332, respectively.

Therefore, the first inlet end 330 is arranged at the position adjacent to the front mopping piece 341, and the second inlet end 332 is arranged at the position adjacent to the rear mopping piece 342, so that the sewage at the contact position between the rolling brush and the ground can be sucked and recovered as soon as possible, the sewage recovery efficiency is improved, and the cleaning effect is guaranteed. To ensure the sewage pumping efficiency, further, the first inlet end 330 faces a part of the outer surface below the axis of the front wiping member 341, and the second inlet end 332 faces a part of the outer surface below the axis of the rear wiping member 342. This location is adjacent to the point where the roller brush contacts the ground where the contaminated water is generated and collected, and the first inlet end 330 and the second inlet end 332 can timely recover the contaminated water.

In one embodiment, the projection of the first inlet end 330 onto the working surface of the floor brush assembly 30 has an overlap with the projection of the front wiper 341 onto the working surface, and correspondingly, the projection of the second inlet end 332 onto the working surface of the floor brush assembly 30 has an overlap with the projection of the rear wiper 342 onto the working surface. The first inlet end 330 is thus located close to the front wiper 341, the second inlet end 332 and the rear wiper 342, ensuring a high recovery efficiency of the contaminated water.

In one embodiment, the rotation directions of the front wiping member 341 and the rear wiping member 342 are set to be opposite, and referring to the state of the floor washing machine shown in fig. 4, the front wiping member 341 is set to rotate counterclockwise, the rear wiping member 342 rotates clockwise, and in the case where the front wiping member 341 and the rear wiping member 342 are driven to rotate, the linear velocity direction of the contact position of the front wiping member 341 with the floor is directed to the side of the first inlet end 330, and the linear velocity direction of the contact position of the rear wiping member 342 with the working surface is directed to the side of the second inlet end 332. Thereby, along with the direction of motion of the rotatory driven sewage of round brush, towards the direction that corresponds dirty import, the dirty import direction motion to corresponding under the inertia effect of the sewage of being convenient for directly, improves sewage recovery's efficiency, guarantees clean effect.

It can be understood that the cleaning liquid tank 50 can provide clean water for mopping the floor, the clean water is sprayed onto the roller brush with fluff through the built-in clean water supply pipeline, the roller brush rotates at high speed to mop the floor, then the sewage after the mopping piece mops the floor enters the pipeline through the dirty inlets arranged in front and at the back of the floor brush assembly 30, the power is provided by the motor, negative pressure and air flow are formed in the dirty inlet and the liquid return pipeline 13, the water in the dirty inlet and the liquid return pipeline 13 is driven to enter the dirty accommodating tank 40, and the processes of washing, mopping and absorbing are completed. However, the liquid return pipe 13 must have a certain length, and in the process that sewage enters the dirty accommodating box 40 through the dirty inlet and the liquid return pipe 13, it must be that sewage exists in each section of the liquid return pipe continuously, when a user finishes one time of work, when the floor cleaning machine is closed, because the suction assembly 20 stops working, the speed of water flow in the liquid return pipe 13 is slower than the speed of air flow, at this time, a small amount of sewage remained in the liquid return pipe 13 is not necessarily recovered completely, when the suction assembly 20 stops working, the sewage flows to the ground under the action of gravity, the flowing sewage drops on the ground, the ground is polluted again, and a user needs to adopt other means to clean and clean, and the use experience is very bad.

In order to solve the above problem, referring to fig. 4, in the floor washing machine according to an embodiment of the present invention, a dirt receiving groove 39 is provided below the dirt collecting port 33, and the dirt receiving groove 39 forms a liquid collecting chamber for temporarily storing the dirt flowing down from the dirt collecting port 33 after the suction module 20 stops operating. Because the dirt collecting port 33 is communicated with the lower end of the liquid return pipeline 13, when the suction assembly 20 stops working, the sewage in the pipeline flows to the ground under the action of gravity, flows to the dirt accommodating groove 39 below and is temporarily stored in the liquid collecting cavity, so that the sewage cannot flow to the ground, and the trouble of secondary cleaning is avoided.

In order to ensure that the dirt does not drip out of the dirt holding tank, the dirt holding tank 39 is arranged such that its projection on the working surface of the floor brush assembly 30 covers the projection of the opening of the dirt collection opening 33 on the floor surface. That is, the projection of the opening of the dirt collection port 33 on the working surface of the floor brush assembly 30 falls within the range of the projection of the dirt holding groove 39 on the working surface. Further, the liquid collection chamber is arranged such that the projection of the opening of the dirt collection port 33 on the work surface of the floor brush assembly 30 covers the projection of the opening of the dirt collection port 33 on the work surface, the projection of the opening of the dirt collection port 33 on the work surface falling within the range of the projection of the liquid collection chamber on the work surface. Wherein the work surface, which should be understood as the work plane of the floor brush assembly 30, is typically the floor, substantially horizontal.

In one embodiment, referring to fig. 4, the first inlet end 330 has a front abutment wall 3301 at the junction adjacent to the dirt collection port 33, the second inlet end 332 has a rear abutment wall 3321 at the junction adjacent to the dirt collection port 33, and the bottom of the dirt holding cavity 39 is configured to be lower than the front abutment wall 3301 and/or the rear abutment wall 3321. Thus, the dirty accommodating groove is sunken to the lower surface that is less than the adjacency of first inlet end 330 and second inlet end 332, and sewage is stored in album liquid intracavity under the action of gravity, as long as the volume of album liquid intracavity sets up rationally, can reduce sewage overflow to the lower surface of first inlet end and second inlet end, flows out to ground and causes the risk of polluting.

The above is only one embodiment of the present invention, and any other modifications based on the concept of the present invention are considered as the protection scope of the present invention.
