Wherein the suction function can be a dust suction function and/or a water suction function.

Taking a floor cleaning machine as an example, the floor cleaning machine is used for wet cleaning of a surface to be cleaned, namely the floor cleaning machine has a suction function and a floor mopping function at the same time. Accordingly, the scrubber also has a clean water tank that supplies cleaning liquid to the roll brush 10 in the cleaning head 100 of the scrubber, thereby wetting the roll brush 10 for cleaning the target object. Correspondingly, the sewage tank 20 is used for collecting the cleaned sewage, so that the sewage enters the sewage tank 20 under the centrifugal action of the rolling brush 10 and the negative pressure of the floor washing machine, the cleaning cleanliness of the floor washing machine is ensured, and the cleaning efficiency of the floor washing machine is improved.

Referring to fig. 2 and 3, the waste water tank 20 includes a tank 1 and a separating mechanism 2 disposed in the tank 1, and the separating mechanism 2 is configured to separate solid and liquid from the waste water after solid-liquid separation. The box body 1 is provided with a sewage inlet 14 and a sewage outlet, a first cavity 11 communicated with the sewage inlet 14 and the sewage outlet is at least formed in the box body 1, and the separating mechanism 2 is arranged in the first cavity 11. Wherein the soil inlet 14 is provided adjacent to the drum brush 10 to shorten a path of soil into the soil tank 20, thereby securing cleaning efficiency of the floor washing machine. And the drain is close to the suction pipe of the scrubber and is arranged in communication with the suction pipe, which is in communication with the main machine of the scrubber, which is activated to form a negative pressure in the sewage tank 20 through the suction pipe. In this embodiment, the sewage draining outlet is an outlet for gas after gas-liquid separation.

The separating mechanism 2 includes a driving member 21 and a first filter member 22 driven by the driving member 21 to rotate. Wherein the driving member 21 is a motor. In the present embodiment, the central axis of the driving member 21 is collinear with the central axis of rotation of the first filter member 22, so that the driving member 21 can smoothly drive the first filter member 22.

In this embodiment, in order to ensure the compactness of the entire sump 20 without occupying space in the cleaner head 100, the sump 20 further includes a supporting fixture 3 disposed in the first chamber 11. The supporting and fixing member 3 is surrounded to form a housing cavity 31, and the driving member 21 is disposed in the housing cavity 31. The accommodating cavity 31 is disposed independently from the first cavity 11, i.e. the accommodating cavity 31 is not communicated with the first cavity 11. The purpose of this is to: the first filter element 22 is driven by the driving element 21 to rotate so as to separate dirt into gas and liquid, and the accommodating cavity 31 is arranged independently of the first cavity 11, so as to prevent the liquid from entering the driving element 21 to cause short circuit of the driving element 21 and influence the operation of the driving element 21. And prevents the metal-made driver 21 from being easily rusted under the influence of the liquid, thereby shortening the service life of the driver 21.

Further, each guide rib 221 is provided on the first filter 22 in a spiral shape or an involute shape, and the extending direction of each guide rib 221 is the same as the rotating direction of the first filter 22. The purpose of this is to: the spiral or involute guide rib 221 has a downward guide effect on dust and sewage, so that the dust and the sewage cannot move upwards, and the dust collection efficiency is improved.

In the height direction of the wastewater tank 20, the length of the first filter 22 in the horizontal direction gradually increases from bottom to top. That is, in this embodiment, the first filter 22 has a funnel shape, so that the dirt remaining in the first cavity 11 can move to the bottom of the first cavity 11 along the funnel-shaped first filter 22, thereby facilitating subsequent cleaning. At the same time, dirt can be made to slide down the guide rib 221.

The first filter member 22 may be fixedly disposed in the first cavity 11. At this time, the top or bottom of the first chamber 11 is detachably provided to the cabinet 1, and the first chamber 11 is cleaned by detaching the top or bottom of the first chamber 11.

Alternatively, the first filter member 22 is also detachably disposed in the first cavity 11. That is, the first filter member 22 is detachably coupled to the driving member 21. The detachable mode can be either the cooperation of the slot and the block or the suction mode, which is a conventional mode and is not described herein. At this time, the first filtering member 22 is further provided with an extracting portion 223, so that when the subsequent cleaning is convenient, the user can directly extract the first filtering member 22 from the first cavity 11 through the extracting portion 223. The extraction portion 223 is located above the first filter 22 in the height direction (indicated by arrow a) of the dirty water tank 20.

When the first filter 22 and the first cavity 11 are detachable, a first cover 8 may be disposed on the first cavity 11, and the first cover 8 rotates relative to the first cavity 11 to open or close the first cavity 11. When the first cavity 11 needs to be cleaned, the first cover 8 is opened and the first filter 22 is taken out, so that the dirt is poured out conveniently and quickly.

Referring to fig. 3 and 5, the separating mechanism 2 further includes a transmission assembly 4 connected to the driving member 21 and an output shaft 5 connected to the transmission assembly 4, wherein the transmission assembly 4 is configured to adjust the rotation speed of the driving member 21 to a set rotation speed, and transmit the rotation speed to the first filter 22 through the output shaft 5. In order to simplify the structure of the transmission assembly 4 and facilitate the arrangement of the separating mechanism 2, and to make the overall structure of the separating mechanism 2 more compact, the transmission assembly 4 includes a first gear 41 connected to the motor shaft of the motor, a plurality of second gears 42 engaged with the first gear 41, and a gear ring 43 sleeved on the periphery of the plurality of second gears 42 and engaged therewith, and the output shaft 5 is connected to the gear ring 43. In the present embodiment, the second gear 42 is provided with 3, that is, 3 second gears 42 and 1 first gear 41 constitute a planetary gear.
