Referring to fig. 1, the main body 1 provided in the present application, which is used for performing a cleaning operation on a surface to be cleaned, may be applied to a cleaning apparatus. The cleaning device includes a floor washing machine, a sweeping and mopping integrated machine, a wet type dust collector and the like, can be a household cleaning device, an industrial cleaning device or a commercial cleaning device, can be a handheld cleaning device or an automatic cleaning device, and is not limited in specific application mode. In the example, the cleaning device includes a body 1, the body 1 includes a body 10, a clean water tank 20, a foul water tank 30, a fan 40, a rolling brush, and other modules, the clean water tank 20, the foul water tank 30, the fan 40, and the rolling brush are all mounted on the body 10, the body 10 has a water channel communicating the clean water tank 20 and the rolling brush, and an air channel communicating the foul water tank 30, the fan 40, and the rolling brush. When the device is used, the water is sprayed to the rolling brush from the water purifying tank 20 through the water channel, the fan 40 works to generate negative pressure, and sewage formed by cleaning the ground by the rolling brush is recycled to the sewage tank 30 through the air channel communicating the rolling brush and the sewage tank 30 and is stored in the sewage tank 30. Of course, the specific structure of the cleaning apparatus is not limited to the above-described example. The following describes the body 1 provided in the present application.

Referring to fig. 2 and 4, a recycling channel 11 is disposed in the housing 10, and a first sub-chamber 31 and a second sub-chamber 32 are formed in the waste water tank 30. When the dirty value of the sewage in the recovery channel 11 is smaller than or equal to a set threshold value, the recovery channel 11 is controlled to be communicated with the first sub-cavity 31; when the dirty value of the sewage in the recovery channel 11 is larger than the set threshold value, the recovery channel 11 is controlled to be communicated with the second sub-cavity 32. It will be understood that the recycling channel 11 is the air duct communicating between the roll brush and the foul water tank 30.

In the prior art, the fresh water tank 20 supplies water to the roll brush so that the roll brush can perform a washing operation on a surface to be cleaned when the body 1 is operated. Meanwhile, the blower 40 operates, and the sewage formed after the cleaning can flow into the sewage tank 30 through the recovery channel 11 and be stored. When the surface to be cleaned is cleaner, the dirty value of the sewage formed after the surface to be cleaned is smaller. If the part of the sewage is directly recycled into the sewage tank 30 and mixed with the sewage having a large value of the sewage and dumped together, it will result in a low utilization rate of the water amount. In addition, in actual operation, since the amount of water in the clean water tank 20 is reduced in real time, frequent water injection into the clean water tank 20 is required to ensure that the machine body 1 can operate normally. Thus, the operation is troublesome, and the user experience is reduced.

In the embodiment provided by the application, due to the arrangement of the first sub-cavity 31 and the second sub-cavity 32, in the operation process, if the contamination value of the sewage in the recovery channel 11 is smaller than or equal to the set threshold value, the recovery channel 11 is controlled to be communicated with the first sub-cavity 31, and the sewage with a smaller contamination value can be recovered to the first sub-cavity 31 to be stored and reused. As can be appreciated, since the dirty value of the dirty water in the first sub-chamber 31 is low, the dirty water in the first sub-chamber 31 can be directly driven to be sprayed toward the roll brush so that the roll brush can perform the cleaning operation. If the dirty value of the sewage in the recovery channel 11 is greater than the set threshold value, the recovery channel 11 is controlled to be communicated with the second sub-cavity 32, and the sewage with the large dirty value can be recovered to the second sub-cavity 32 to be stored. And because the dirty value of the interior sewage of second sub chamber 32 is great, for convenient operation, can directly empty the department of retrieving waste water with the sewage in the second sub chamber 32 after reaching a certain amount. Of course, in other embodiments, the waste water in the second sub-chamber 32 can be reused after being purified.

Therefore, by arranging the first sub-cavity 31 and the second sub-cavity 32, the first sub-cavity 31 and the second sub-cavity 32 can store sewage with different dirty values respectively, so that the sewage with smaller dirty values can be recycled conveniently, and the water utilization rate is higher. Moreover, because the sewage in first subchamber 31 can also be recycled and be used for wasing, so, still can reduce the water injection frequency of water purification case 20 to can further promote the simplicity and convenience of operation, therefore have higher user experience degree.

It is worth mentioning that the first sub-chamber 31 may supply water to the rolling brush when the clean water in the clean water tank 20 is completely used up, or may supply water to the rolling brush when the polluted water therein reaches a set water level.

The recovery channel 11 includes a main channel 112, a first branch flow 114 and a second branch flow 116, the first branch flow 114 is communicated between the main channel 112 and the first sub-chamber 31, and the second branch flow 116 is communicated between the main channel 112 and the second sub-chamber 32. The machine body 1 further comprises a first water inlet valve, a second water inlet valve, a first water inlet pipe 50 and a second water inlet pipe 60, wherein a first water inlet channel 52 is formed in the first water inlet pipe 50, and a second water inlet channel 62 is formed in the second water inlet pipe 60. First inlet channel 52 communicates between first branch 114 and first subchamber 31, and second inlet channel 62 communicates between second branch 116 and second subchamber 32. The first water inlet valve is configured to conduct the first branch flow 114 when the dirty value of the dirty water in the main flow passage 112 is less than or equal to a set threshold value, so that the dirty water with a smaller dirty value can be recovered into the first sub-chamber 31 through the first branch flow 114 and the first water inlet channel 52 and stored. The second water inlet valve is configured to conduct the second branch flow 116 when the dirty value of the dirty water in the main flow passage 112 is greater than a set threshold value, so that the dirty water with a large dirty value can be recovered to the second sub-chamber 32 through the second branch flow 116 and the second water inlet channel 62 and stored. The first branch flow 114 and the first branch flow 114 are respectively controlled to be switched on and switched off by arranging the first water inlet valve and the second water inlet valve, so that the flow direction of sewage can be accurately controlled, and the sewage with different pollution values can be conveniently recycled.

It is understood that the first and second water inlet valves may be separate valve structures, or alternatively, the first and second water inlet valves may be combined together to form a two-way valve.

Further, the main body 1 further includes a contamination detecting member coupled to the main body 10 and configured to detect a contamination level of the contaminated water in the main flow passage 112. It can be understood that, in the working process, the contamination detection component can detect the contamination value of the contamination in the main flow channel 112 in real time, and the first water inlet valve and the second water inlet valve are asynchronously started according to the contamination value detected by the contamination detection component. Through setting up dirty detection piece to the dirty degree of sewage can be implemented to user or controller, thereby can be accurate retrieve its classification according to the dirty degree of sewage.

Alternatively, the contamination detecting member may be an infrared detecting member, a contamination value detecting member, or another type of detecting member, and only needs to be able to accurately collect the contamination value of the sewage in the main flow passage 112 in real time.

Referring also to fig. 3, in some embodiments, the body 1 further includes a purification assembly 80, and the purification assembly 80 is disposed in the first sub-cavity 31 and configured to purify the wastewater in the first sub-cavity 31. Optionally, the purification assembly 80 can physically adsorb the dirt in the sewage in the first sub-chamber 31, or the purification assembly 80 can release a chemical reagent that can react with the dirt in the sewage to remove the dirt.

Preferably, the purification assembly 80 includes activated carbon, which can effectively adsorb dirt in the sewage and does not generate new chemical substances, thereby being more environmentally friendly.

In addition, purify subassembly 80 still includes the one-level filter screen and the second grade filter screen that set gradually along the direction of gravity, and the active carbon sets up between one-level filter screen, second grade filter screen, and the mesh of one-level filter screen is greater than the mesh of second grade filter screen. In this embodiment, one end of the first water inlet channel 52, which is away from the first branch flow 114, extends upwards into the first sub-cavity 31, the side wall of the waste water tank 30 is further opened with a discharge port communicated with the first sub-cavity 31, and the water outlet of the first water inlet channel 52, which is located in the first sub-cavity 31, is located above the discharge port. The purifying component 80 is abutted between the outer wall of the first water inlet pipe 50 and the inner wall of the first sub-chamber 31, and in the gravity direction, the height of the purifying component 80 from the water outlet of the first branch flow 114 is less than the height of the water outlet of the first water inlet channel 52 from the water outlet of the first branch flow 114, and is greater than the height of the discharge port from the water outlet of the first branch flow 114. Then the dirty value is less than the delivery port blowout back of setting for threshold value by first water inlet channel 52 under fan 40's effect, under the effect of gravity, sewage can flow into the space that is located the purification subassembly 80 below in the first subchamber 31 after purifying the one-level filter screen in the subassembly 80, active carbon and second grade filter screen filtration, and solid-state dirty then is blockked in the top of purifying the subassembly 80 to can effectively separate solid-state dirty and liquid water.

Preferably, the hook portion 33 is disposed on the inner wall of the first sub-cavity 31, the purifying assembly 80 includes a purifying member 81 and a hook 83, the purifying member 81 may include the above-mentioned activated carbon, or may also include the above-mentioned primary filter screen, activated carbon and secondary filter, and the hook 83 is coupled to the purifying member 81 and detachably hooked to the hook portion 33, so as to fix the purifying assembly 80.

Of course, the installation manner of the purification assembly 80 is not limited to the above-mentioned one, and in other embodiments, the purification assembly 80 may be detachably fixed by snapping, adhering, or other manners.

In some embodiments, the body 1 further comprises a water outlet assembly 90 and a rolling brush, both coupled to the body 10, wherein the water outlet assembly 90 is configured to drive the dirty water in the first sub-cavity 31 to spray toward the rolling brush when the water level in the first sub-cavity 31 is greater than the set water level. Through setting up out water subassembly 90, to supplying sewage to the round brush when the water level is greater than the settlement water level line in first sub-chamber 31 to can recycle the sewage in the first sub-chamber 31. It will be appreciated that the set water level may be set as desired, but to ensure that the roller brush is able to continue to operate for a period of time, the set water level should be higher.

The water outlet assembly 90 includes a water pump 91, a first water outlet pipe 92 and a first water outlet valve, the first water outlet pipe 92 is formed with a first water outlet channel 921 communicated between the water inlet end of the water pump 91 and the first sub-cavity 31, and the first water outlet valve is coupled to the first water outlet pipe 92 and configured to conduct the first water outlet channel 921 when the water level line in the first sub-cavity 31 is greater than the set water level line. It will be appreciated that the first outlet passage 921 communicates with the first subchamber 31 through the drain opening. When the water level in the first sub-chamber 31 is greater than the set water level, the first water outlet valve is opened, and the water pump 91 drives the sewage in the first sub-chamber 31 to flow to the rolling brush, so as to ensure that the first sub-chamber 31 can supply water for the rolling brush. When the water level line in the first sub-cavity 31 is smaller than or equal to the set water level line, the first water outlet valve is closed, the first sub-cavity 31 stops supplying water to the rolling brush, and sewage with a small pollution value flows into the first sub-cavity 31 and is stored.

Preferably, the body 1 further includes a water level detecting member 70, the water level detecting member 70 being fitted in the first sub-chamber 31 and configured to detect a water level in the first sub-chamber 31. The water level detecting member 70 can monitor the water level in the first sub-chamber 31 in real time, and when the water level reaches the set water level, the user or the controller can control the first water outlet valve to open. Specifically, the water level detection member 70 may be an electrode detection member, a laser detection member, or the like. In addition, if the height of the water level line relative to the water outlet of the first substream 114 is set to be smaller than the height of the purification component 80 from the water outlet of the first substream 114, solid-liquid separation can be achieved in the first subchamber 31.

In some embodiments, the fuselage 1 further comprises a clean water tank 20, the clean water tank 20 having a clean water cavity 21; the outlet assembly 90 further includes a second outlet pipe 93 and a second outlet valve, a second outlet channel 932 is formed in the second outlet pipe 93 and is connected between the purified water chamber 21 and the first outlet channel 921, and the second outlet valve is configured to open the second outlet channel 932 when the water level in the first sub-chamber 31 is less than or equal to the set water level.

Specifically, the water pump 91 is always on when the body 1 is operating. If the water level in the first sub-chamber 31 is less than or equal to the set water level, the second air outlet valve is opened, and the water pump 91 drives the purified water in the purified water tank 20 to be sprayed to the rolling brush. If the water level in the first sub-chamber 31 is higher than the set water level, the second outlet valve is closed to prevent the water in the clean water tank 20 from flowing out and being wasted. At the same time, the first outlet valve is opened, and the sewage in the first sub-chamber 31 flows to the rolling brush under the action of the water pump 91. Therefore, by arranging the water pump 91, the water purification cavity 21 or the first sub-cavity 31 can be ensured to supply water to the rolling brush asynchronously, and the first water outlet valve and the second water outlet valve are selected to be started, so that the water can be saved while the machine body 1 can work normally.

Of course, in other embodiments, the operation of the water outlet assembly 90 is not limited to the above-mentioned one, for example, when the water level in the first sub-chamber 31 is greater than the set water level, the first water outlet valve and the second water outlet valve can be opened simultaneously, so as to supply a large amount of water to the rolling brush.

It can be understood that the first water outlet channel 921 includes a water inlet section 923 and a water outlet section 925 which are communicated with each other, the water inlet section 923 is communicated with the first sub-chamber 31, and the second water outlet channel 932 is communicated with the water outlet section 925. The first outlet valve is used for switching on or off the water inlet section 923, and the second outlet valve is used for switching on or off the second outlet channel 932.

In other embodiments, a third outlet valve is further disposed on the outlet section 925, and the third outlet valve is used for controlling the opening or closing of the outlet section 925. By arranging the third water outlet valve, the reliability of water outlet and water cut-off can be further improved.

Preferably, the first outlet valve, the second outlet valve and the third outlet valve are combined to form a three-way valve 94. That is, the first outlet valve, the second outlet valve, and the third outlet valve are each part of the structure within the single three-way valve 94. By providing the three-way valve 94, the use of internal parts of the body 1 can be reduced, thereby achieving high assembly efficiency.

The water outlet assembly 90 further includes a first switch valve 95 and a second switch valve 96, and the first switch valve 95 and the second switch valve 96 are respectively disposed at the drain outlet of the sewage tank 30 and the water inlet of the second water outlet channel 932, so as to further improve the reliability of the opening and closing of the first water outlet channel 921. When first ooff valve 95 closed, sewage is stored in first subchamber 31, and when first ooff valve 95 opened, the sewage in first subchamber 31 can flow out. Similarly, when the second switch valve 96 is closed, the purified water is stored in the purified water chamber 21, and when the second switch valve 96 is opened, the purified water can flow out of the purified water chamber 21.

In some embodiments, the body 1 further includes a controller electrically connected to the dirt detecting element, the first inlet valve, the second inlet valve, the water pump 91, the first outlet valve, the second outlet valve, the third outlet valve, the first switch valve 95, the second switch valve 96 and the water level detecting element 70, and the controller is configured to control the dirt detecting element, the first inlet valve, the second inlet valve, the water pump 91, the first outlet valve, the second outlet valve, the third outlet valve, the first switch valve 95, the second switch valve 96 and the water level detecting element 70 to operate.

Next, the specific operation of the entire body 1 in one embodiment will be described in detail as follows.

During operation, the controller controls the water pump 91, the blower 40, the rolling brush, the dirt detecting element and the water level detecting element 70 to be started, controls any one of the first water inlet valve and the second water inlet valve to be opened, controls the second water outlet valve, the third water outlet valve and the second switch valve 96 to be opened, and controls the first water outlet valve and the first switch valve 95 to be closed. The clean water in the clean water chamber 21 flows to the roll brush through the second water outlet passage 932 and the water outlet section 925 of the first water outlet passage 921 by the water pump 91, and the cleaned sewage can flow into the main flow passage 112 of the recovery passage 11 by the fan 40. The contamination detecting member detects a contamination value of the contaminated water in the main flow passage 112 and sends the value to the controller, and the water level detecting member 70 detects a water level line in the first sub-chamber 31 and sends the value to the controller.

When the dirt value is larger than the set threshold value, if the first water inlet valve is opened before the dirt value is larger than the set threshold value and the second water inlet valve is closed before the dirt value is larger than the set threshold value, the controller controls the first water inlet valve to be closed and controls the second water inlet valve to be opened. If the first water inlet valve is closed before the first time and the second water inlet valve is opened before the second time, the controller controls the first water inlet valve and the second water inlet valve to maintain the original working state unchanged. Thus, the contaminated water having a large value of contamination can be recovered into the second sub-chamber 32.

When the dirt value is smaller than or equal to the set threshold value, if the first water inlet valve is opened before the dirt value is smaller than or equal to the set threshold value and the second water inlet valve is closed before the dirt value is smaller than the set threshold value, the controller controls the first water inlet valve and the second water inlet valve to maintain the original working state unchanged. If the first water inlet valve is closed and the second water inlet valve is opened before that, the controller controls the first water inlet valve to be opened and controls the second water inlet valve to be closed. Thus, the contaminated water having a small value of contamination can be recovered into the first sub-chamber 31.

When the water level in the first sub-chamber 31 reaches the set water level, the controller controls the first water outlet valve and the first switch valve 95 to open, and controls the second water outlet valve and the second switch valve 96 to close, so that the water purifying tank 20 stops supplying water to the rolling brush, and the sewage in the first sub-chamber 31 supplies water to the rolling brush.

When the sewage in the first sub-chamber 31 decreases below the set water level, the first outlet valve and the first on-off valve 95 are controlled to be closed again, and the second outlet valve and the second on-off valve 96 are controlled to be opened.

After the operation is finished, the controller controls the water pump 91, the blower 40, the rolling brush, the dirt detecting member, the water level detecting member 70, the first water inlet valve, the second water inlet valve, the first water outlet valve, the second water outlet valve, the third water outlet valve, the first switch valve 95 and the second switch valve 96 to be closed.
