The suction piece 15 is arranged in the negative pressure channel 104, the air inlet side of the suction piece 15 is communicated with the air inlet 102, and the air outlet side of the suction piece 15 is communicated with the air outlet 103, so that air can enter from the air inlet 102 and finally be discharged from the air outlet 103. During cleaning, when the suction member 15 is activated, the suction member 15 generates negative pressure at the end (the suction port 112) of the suction channel 111 through the suction flow channel, so that dirt such as dust, liquid and the like on the ground can be sucked into the suction flow channel of the waste water tank 40 from the suction channel 111, in the suction flow channel, the dust, liquid and the like can be left in the waste water tank 40, and air can flow from the air outlet to the air inlet 102 to the negative pressure channel 104, and finally flows through the air outlet 103 and the air exhaust gap 17 in sequence to be exhausted. Wherein the sump 40 is at least partially spaced apart from the body 10 to form the discharge gap 17. Optionally, the suction piece 15 is a fan. In addition, in other embodiments, the suction member 15 may be installed at the air outlet of the foul water tank 40.

Through being formed with air exhaust clearance 17 between sewage case 40 and organism 10 for air exhaust clearance 17 communicates with air exit 103 on the organism 10, thereby in the floor cleaning machine working process, air exit 103 exhaust air current need be discharged through air exhaust clearance 17, so set up air exhaust clearance 17 and be equivalent to the length that has prolonged the last air exhaust duct of floor cleaning machine, and air exhaust clearance 17's size length can set up great, realizes the many positions air-out, effectively reduces the air-out noise. The air flow is prevented from being intensively exhausted at one position, so that the generated noise is excessive.

In some embodiments, the exhaust outlet 103 is located at one side of the intake opening 102, a suction flow path communicating the suction passage 111 with the intake opening 102 is provided in the sewage tank 40, and an exhaust flow path communicating the exhaust outlet 103 with the exhaust gap 17 is provided between the sewage tank 40 and the installation site. Therefore, the air outlet 103 and the air inlet 102 can be arranged in a centralized manner, and the forming is convenient.

In some embodiments, the mounting station includes a bottom mounting platform 13 and a mounting recess 107 on one side of the mounting platform 13, the waste tank 40 is mounted on the mounting platform 13, and one side of the waste tank 40 is partially located in the mounting recess 107 and abuts against a side wall of the mounting recess 107.

The mounting platform 13 is formed with a first through-hole communicating with the suction passage 111, and the soil inlet 402 communicates with the first through-hole when the soil tank 40 is mounted on the mounting platform 13. When the air exhaust gap 17 is formed between the bottom of the sewage tank 40 and the mounting platform 13, the length of the air exhaust duct on the floor washing machine is longer, and the air exhaust noise is further reduced. And the air discharge gap 17 between the bottom of the sewage tank 40 and the mounting platform 13 can be made as close as possible to the lower portion of the floor washing machine, so that the air current discharged from the air discharge gap 17 can be prevented from blowing toward the upper body of the user.

A partial discharge gap 17 (side gap 172) is formed between the wall of the mounting groove 107 and the side of the foul water tank 40. The foul water tank 40 is thus mounted at least partially to the mounting groove 107 and abuts against the side wall of the mounting groove 107. The arrangement of the mounting groove 107 facilitates the positioning and mounting of the sewage tank 40, and the mounting groove 107 can limit the transverse movement of the sewage tank 40 relative to the machine body 10, and can increase the contact area between the sewage tank 40 and the machine body 10, thereby improving the mounting stability of the sewage tank 40.

In some embodiments, the discharge gap 17 includes a bottom gap 171 and a side gap 172, the bottom gap 171 being formed between the bottom of the wastewater tank 40 and the mounting platform 13, and the side gap 172 being formed between the side of the wastewater tank 40 and the mounting groove 107. Specifically, the side gaps 172 and the bottom gap 171 are both in communication with the air discharge opening 103, and when the air flow flows out of the air discharge opening 103, a part of the air flow is discharged from the side gaps 172, and the other part is discharged from the bottom gap 171.

In some embodiments, the gap width of the bottom gap 171 is greater than the gap width of the side gaps 172. So set up, can be so that the air-out resistance of lateral part clearance 172 is great to make the reposition of redundant personnel that the air-out air current can be better to bottom clearance 171, avoid the air-out air current to concentrate the condition of flowing out from lateral part clearance 172, make the air current of flowing out from bottom clearance 171 and lateral part clearance 172 comparatively even, can further reduce the air-out noise. And through adjusting the gap width ratio of bottom clearance 171 and lateral part clearance 172, can regard bottom clearance 171 as the main position of airing exhaust, so can prolong the air-out wind channel better, and in the in-process of air-out air current flow direction bottom clearance 171, still partial air current flows out from lateral part clearance 172, and the noise reduces during the time of can making the air-out.
