During the cleaning process of the floor brush 200, the area to be cleaned may be wet-towed by one of the first cleaning member 220a and the second cleaning member 220b, then the spray channel 211 passes through the area, the stubborn stains are removed by washing with hot water or high-temperature steam, and finally the other of the first cleaning member 220a and the second cleaning member 220b is wiped dry through the area.

For example, the heating module 231 may be disposed between the injection passage 211 and the first cleaning member 220a, or the heating module 231 is disposed between the injection passage 211 and the second cleaning member 220b, so that the distance between the heating module 231 and the injection passage 211 is short, and thus the path of the flow of hot water or steam is short, avoiding heat loss.

The spray channel 211 may be located at an intermediate position between the first cleaning member 220a and the second cleaning member 220b, for example, the spray channel 211 may be disposed parallel to the first cleaning member 220a and the second cleaning member 220b, and the distance of the spray channel 211 from the first cleaning member 220a and the distance from the second cleaning member 220b may be equal or approximately equal, such that two relatively independent mounting areas are formed at both sides of the spray channel 211 to facilitate the arrangement of the heating module 231 and other components.

In addition, the water pressure formed by the first driving unit 233 can make the hot water or the high-temperature steam sprayed from the spraying channel 211 have a certain impact force, so that the cleaning effect on stubborn stains is better.

In some embodiments, the side of the spray channel 211 facing the heating module 231 may be provided with a connection protrusion 2112, the connection protrusion 2112 having a pipe joint 2113, and the thermal cleaning assembly 230 may further include a steam conduit 234, the steam conduit 234 being connected between the outlet of the heating module 231 and the pipe joint 2113.

It will be appreciated that hot water or high temperature steam flowing from the heating module 231 may enter the steam conduit 234, pass through the steam conduit 234 and then enter the injection passage 211 through the pipe joint 2113, and the connection protrusion 2112 may further shorten the path between the heating module 231 and the injection passage 211, i.e. shorten the length of the steam conduit 234, so that hot water and steam flowing from the heating module 231 may be rapidly injected into the injection passage 211.

The first check valve 235 and the second check valve 246 are disposed side by side on the same side of the injection passage 211, so that when the pipes of the water supply assembly 300 are connected, the water paths of the water supply assembly 300 into the thermal cleaning assembly 230 and the cleaning assembly 240 can be concentrated, thereby improving the convenience of the pipe connection.

It will be appreciated that the portion of the detecting member 421 located in the sewage chamber 401 may be regarded as a conductive contact, when the sewage level in the sewage chamber 401 does not reach the height of the detecting member 421, the conductive contact of the detecting member 421 is only in contact with air, the resistance is approximately infinite, when the sewage level in the sewage chamber 401 rises to the height of the detecting member 421, the conductive contact of the detecting member 421 contacts sewage, and since the sewage has conductive property, the electrical signal fed back to the controller by the detecting member 421 changes, thereby judging that the sewage level in the sewage chamber 401 reaches the full level, i.e. judging that the sewage tank 400 is full.

It should be noted that, the cleaning device provided in this embodiment of the present application detects the water level in the sewage tank 400 by setting the water level detection assembly 420 to determine whether the sewage in the sewage tank 400 is full, so that when the sewage reaches the full water level, the cleaning device can stop working to prompt cleaning the sewage so as to avoid overflow of the sewage.

The specific mounting structure of the water level detecting unit 420 and the manner of deriving the electric signal of the detecting member 421 will be described in detail.

In addition, one of the conductive spring pin 422 and the switching contact 212 can elastically float, so that when the conductive spring pin 422 and the switching contact 212 are abutted, the abutting pretightening force can be provided by utilizing elasticity, and the conductive spring pin 422 and the switching contact 212 can be ensured to always maintain a good electric connection state.

Illustratively, the fixing cover plate 423 may be detachably fixed to the sidewall of the sewage tank 400, for example, the fixing cover plate 423 may be connected to the sidewall of the sewage tank 400 by a fastener such as a bolt or a screw, and the sidewall of the sewage tank 400 may be provided with a groove in which the water level detecting assembly 420 may be disposed, and the shape of the fixing cover plate 423 may be matched with that of the groove, thereby ensuring the flatness of the external appearance of the sewage tank 400.

In some embodiments, a side of the fixed cover plate 423 facing the sewage tank 400 may abut against the detecting member 421, a sidewall of the sewage tank 400 may have a through hole, the detecting member 421 may be inserted into the through hole, the water level detecting assembly 420 may further include a first sealing member 424, the first sealing member 424 may be sleeved on the detecting member 421, and the first sealing member 424 abuts between the detecting member 421 and an outer wall of the sewage tank 400.

In addition, the number of the water level detecting components 420 may be plural, and the detecting members 421 of the water level detecting components 420 may be distributed at different positions along the length direction of the sewage chamber 401 along the sewage tank 400, so as to improve the accuracy of determining the water level in the sewage tank 400. For example, two water level detecting units 420 may be disposed at two ends of the same sidewall of the sewage tank 400, and when the sewage tank 400 is inclined, at least one water level detecting unit 420 may still detect whether sewage is in a full water level state, thereby avoiding sewage leakage. The brush body 210 may be provided with a plurality of transfer contacts 212 at corresponding positions, and the positions of the transfer contacts 212 may correspond to the conductive pins 422 of the water level detection assembly 420 one by one when the sewage tank 400 is mounted to the brush 200.

The structure of the sewage recovery of the sewage tank 400 and the sewage recovery method will be described in detail.

In one possible implementation, the cleaning apparatus may further include an air suction fan 500, and the floor brush 200 may further include an air suction duct 270, the air suction fan 500 being in communication with the air suction duct 270, and an air inlet 271 of the air suction duct 270 being in communication with the sewage chamber 401, such that a negative pressure may be formed in the sewage chamber 401.

It can be understood that when the suction fan 500 is operated, the air flow formed by the suction fan 500 flows into the suction air channel 270 from the sewage chamber 401, and is discharged from the suction air channel 270 through the suction fan 500, and when the interior of the sewage chamber 401 is in a negative pressure state, the sewage generated by the cleaning member 220 can be pumped into the sewage tank 400, so that the sewage recovery efficiency is improved. The size of the negative pressure for sewage recovery in the sewage cavity 401 depends on the power of the air suction fan 500, and the power of the air suction fan 500 can be adjusted, so that the power of different suction sizes is adopted according to different application scenes.

In some embodiments, the tank 410 has a sewage inlet 411 and an air suction 412, the sewage inlet 4111 of the sewage inlet 411 is communicated with the sewage recovery pipe 250, the sewage chamber 401 may be provided with a sewage suction port 402, the sewage suction port 402 is communicated with the sewage inlet 411, the air suction 412 has an air outlet 4121 and an air suction port 4122, the air outlet 4121 may be abutted and communicated with the air inlet 271 of the air suction duct 270, and the air suction port 4122 may be communicated with the sewage chamber 401.

It will be appreciated that the air flow in the tank 400 may enter the suction duct 412 from the suction inlet 4122 and flow from the outlet 4121 into the suction duct 270, thereby creating a negative pressure in the sewage chamber 401. The negative pressure air flow formed in the sewage chamber 401 can suck sewage into the sewage chamber through the sewage suction port 402, that is, the sewage generated by the cleaning member 220 is first introduced into the sewage recovery pipe 250, then introduced into the sewage inlet pipe 411 through the inlet port, and finally introduced into the sewage chamber 401 from the sewage suction port 402. Thus, on one hand, the backflow of sewage in the sewage suction cavity 401 under the action of gravity can be avoided, and on the other hand, the sewage in the sewage suction cavity 401 can be prevented from entering the air suction duct 270, so that the drying of the working environment of the air suction fan 500 is ensured.

Illustratively, the suction inlet 402 and the suction inlet 4122 may be located on opposite sides within the sewage chamber 401, such that the separation distance between the suction inlet 402 and the suction inlet 4122 may be increased, preventing sewage from splashing into the suction duct 412. For example, the suction inlet 402 and the suction inlet 4122 may be located at both ends of the sewage tank 400 in the length direction of the sewage tank 400.

In some embodiments, the dirt inlet duct 411 may be located at the bottom wall of the dirt cavity 401 and the dirt pickup 402 may be oriented toward the top wall of the dirt cavity 401, thereby facilitating the docking of the dirt inlet duct 411 with the dirt recovery tube 250 on the floor brush 200. The suction duct 412 may be located at a top wall of the sewage chamber 401 to increase a distance between the suction duct 412 and a sewage surface in the sewage chamber 401 so that surface sewage enters the suction duct 412.

To provide a barrier to the surge of sewage within the sewage chamber 401, the sewage tank 400 may further include a first barrier 413, and the first barrier 413 may be disposed around the sewage suction port 402. In addition, the sewage tank 400 may further include a second baffle 414, and the second baffle 414 may be disposed around the suction inlet 4122, so that sewage is prevented from splashing into the suction duct 412. It should be noted that, only one of the first baffle 413 and the second baffle 414 may be provided, or both may be provided, which is not particularly limited in the embodiment of the present application.

Illustratively, the first baffle 413 and the second baffle 414 may be integrally formed with the tank 410, or the first baffle 413 and the second baffle 414 may be welded to a wall of the sewage chamber 401, which is not specifically limited in the embodiment of the present application.

In one possible implementation, the sewage tank 400 may further include a first filter 430 and a pressure plate 431, the first filter 430 may be disposed at the air suction port 4122, the pressure plate 431 may be located at a side of the first filter 430 facing away from the wall of the sewage chamber 401, and the pressure plate 431 abuts against the first filter 430.

It will be appreciated that when the air flow enters the air suction duct 412 from the sewage chamber 401, the air flow will first flow through the first filter 430, so that the first filter 430 can filter the air flow entering the air suction duct 412, thereby ensuring the air flow counted into the air suction duct 270 to be dry and clean, and avoiding the damage of the air suction fan 500.

Illustratively, the first filter 430 may be a sponge or other breathable and absorbent material, such that even if some water vapor or water droplets enter the inlet port 4122 with the airflow, the water vapor or water droplets may be absorbed by the first filter 430.

In addition, the pressing plate 431 can also play a role of blocking while fixing the first filter 430, so that the first filter 430 is prevented from being wetted by swashing or splashed sewage, and the filtering effect of the first filter 430 is reduced. The pressing plate 431 may be detachably installed with the cavity wall of the sewage tank 400 by means of screws, etc., so that the first filter 430 is conveniently replaced, thereby ensuring that the first filter 430 can maintain a good filtering and water absorbing effect.

Illustratively, the grating plate 415 may be connected to opposite side walls of the sewage chamber 401, and the grating plate 415 may be provided with water passing holes from dividing the sewage chamber 401 into two receiving areas arranged along the length direction of the sewage tank 400. The sewage suction port 402 may be disposed in the accommodating area a, the air suction port 4122 may be disposed in the accommodating area b, when the sewage is mixed with impurities, the impurities will remain in the accommodating area a due to the blocking of the grating plate 415 after the impurities enter the accommodating area a from the sewage suction port 402, and the sewage may enter the accommodating area b from the water passing holes of the grating plate 415, thereby separating the impurities.
