Referring to fig. 1, the present application provides a cleaning apparatus that can be used to clean a floor. The cleaning device may be a scrubber, a sweeping robot, a mopping robot, etc., and the following embodiments are described with reference to the cleaning device as a scrubber.

The cleaning apparatus comprises a frame (not shown), a clean water tank (not shown), a suction assembly (not shown), a sewage tank 1, a floor brush assembly and a control system (not shown). The floor brush assembly is arranged at the bottom of the frame, and the clean water tank and the sewage tank 1 are both arranged on the frame and are in fluid communication with the floor brush assembly, and the clean water tank is used for providing cleaning water for the floor brush assembly; the suction component is arranged on the frame and connected with the sewage tank 1, and can enable negative pressure to be formed in the sewage tank 1 so as to recycle sewage after the cleaning of the floor brush component to the sewage tank 1; the control system controls the clean water tank to provide cleaning water for the floor brush assembly and controls the suction assembly to recycle sewage after the floor brush assembly is cleaned into the sewage tank 1.

Referring to fig. 2 and 3, in particular, the sewage tank 1 is commonly arranged on the rack in various manners. For example, as shown in fig. 1, the sewage tank 1 may be vertically provided on the rack. Alternatively, as shown in fig. 2, the sewage tank 1 is inclined against the frame. Alternatively, as shown in fig. 3, the sewage tank 1 is laid on the frame. Of course, the arrangement form of the sewage tank 1 is not limited to the above-mentioned three common types. In some embodiments, for a push-pull type floor washing machine (a floor washing machine which needs to be manually pushed and pulled to be movable and cleaned, like a mop structure), the state when the sewage tank 1 is vertically arranged on the rack is set to be a non-operating state of the sewage tank 1, and the state when the sewage tank 1 is inclined against the rack is set to be a normal operating state of the sewage tank 1. When the sewage tank 1 is in the non-operating state, the sewage tank 1 is in a stage of being ready to start operation, and at this time, the sewage tank 1 is not used for collecting sewage. When the sewage tank 1 is in a normal working state, the sewage tank 1 is used for collecting sewage. For a fully automatic floor washing machine (a floor washing machine capable of automatically walking on the ground and cleaning), the sewage tank 1 is always laid on the rack in a non-working state or a normal working state. The following embodiments will be described by taking as an example any one of the above three arrangements of the upright, reclined and lying arrangement of the sewage tank 1 in normal operation.

Referring to fig. 4 and 5, the sewage tank 1 includes a main body 10 and a partition member 20. The main body 10 is provided with an air inlet duct 13 and a cavity 14 which are independent of each other, the separation assembly 20 is arranged in the cavity 14, and the cavity 14 is separated to form a dirt holding cavity 141 and a separation cavity 142 which are independent of each other. Wherein the air outlet end of the air inlet duct 13 is in fluid communication with the separation chamber 142; the partition assembly 20 is configured to have a conductive state allowing sewage in the separation chamber 142 to flow into the sewage receiving chamber 141 and a blocking state preventing fluid communication between the separation chamber 142 and the sewage receiving chamber 141.

The main body 10 is provided with an air inlet 111 and an air outlet 112, the dirt inlet of the air inlet duct 13 is communicated with the air inlet 111, the air inlet duct 13 extends along the direction (the direction indicated by an arrow X in fig. 1) of the air inlet 111 pointing to the air outlet 112, and the air outlet 112 is communicated with the cavity 14. When the sewage tank 1 is vertically arranged on the frame, the direction of the air inlet 111 pointing to the air outlet 112 is the vertical upward direction. When the sewage tank 1 leans against the rack, the included angle between the direction of the air inlet 111 pointing to the air outlet 112 and the vertical direction is an acute angle. When the sewage tank 1 is laid on the frame, the direction of the air inlet 111 pointing to the air outlet 112 is the horizontal direction.

Alternatively, the partition assembly 20 may be rotated with respect to the main body 10 to switch its state. For example, when the partition member 20 rotates forward relative to the main body 10 (for example, in fig. 1, the forward rotation is in a clockwise rotation direction indicated by an arrow P1), a gap is formed between the partition member 20 and the cavity wall of the cavity 14, and the partition member 20 is switched to the conductive state; when the partition member 20 rotates in the reverse direction (in fig. 1, the reverse rotation is a counterclockwise rotation indicated by an arrow P2, for example) with respect to the main body 10, the partition member 20 is in close contact with the wall of the cavity 14, and the partition member 20 is switched to the blocking state.

Alternatively, the separation assembly 20 may also be adapted to switch its state by translating relative to the body 10. For example, in the direction in which the air inlet 111 points to the air outlet 112, the cross-sectional area of the main body 10 gradually increases, and when the partition assembly 20 translates along the direction in which the air inlet 111 points to the air outlet 112 relative to the main body 10, the partition assembly 20 is switched to the on state; when the partition assembly 20 translates along the direction from the air outlet 112 to the air inlet 111 relative to the main body 10, the partition assembly 20 is switched to the blocking state.

Of course, the mode of switching the state of the partition assembly 20 is not limited to the above, but may be other modes, and the specific modes thereof are not limited herein.

The suction assembly is in fluid communication with the air outlet 112 of the main body 10, and when the suction assembly is in operation, a mixed fluid formed by mixing solid, liquid and air flows into the first subchamber 143 through the air inlet duct 13 and is separated (the flow direction of the mixed fluid is indicated by arrows a-b-c in fig. 1). The solid garbage is blocked by the solid-liquid separator 30 and stored in the first subchamber 143, the sewage is separated into the second subchamber 144 by the solid-liquid separator 30, the density of the gas is smaller than that of the solid garbage and the sewage, and the gas can be discharged to the outside through the air outlet 112 (the flowing direction of the gas is indicated by arrows d-e in fig. 1).

When the partition assembly 20 is in the on state, the sewage in the separation chamber 142 can flow into the sewage containing chamber 141 for storage. When the water storage amount of the sewage in the sewage containing chamber 141 reaches the set water storage amount, the partition assembly 20 is switched to the blocking state to close the sewage stored in the sewage containing chamber 141, so as to prevent the sewage in the sewage containing chamber 141 from overflowing to the outside through the separation chamber 142. Wherein, a small portion of the sewage in the sewage containing cavity 141 may overflow to the outside through the separating cavity 142 and the air inlet duct 13, and the sewage in the sewage containing cavity 141 may overflow to the suction assembly (e.g. fan) mainly through the separating cavity 142 and the air outlet 112 of the main body 10, resulting in the failure of the suction assembly. Due to the arrangement of the dirt holding cavity 141 and the separation component 20, when the separation component 20 blocks the fluid communication between the separation cavity 142 and the dirt holding cavity 141, the water quantity in the separation cavity 142 is relatively small all the time, so that excessive sewage can be prevented from flowing and overflowing everywhere in the space when the cleaning equipment is pushed back and forth along the horizontal direction. Therefore, the sewage tank 1 provided in the application can reduce the risk of sewage flowing out to the outside, and is helpful for improving the experience of users.

In some embodiments of the present application, the sewage tank 1 includes a solid-liquid separator 30 disposed in the separation chamber 142, and the solid-liquid separator 30 separates the separation chamber 142 to form a first subchamber 143 and a second subchamber 144. Wherein the air outlet end of the air inlet duct 13 is in fluid communication with the first subchamber 143, and the second subchamber 144 is located at one side of the first subchamber 143 and in fluid communication with the first subchamber 143. When the partition assembly 20 is in the on state, the partition assembly 20 allows the sewage in the second sub-chamber 144 to flow into the sewage containing chamber 141. When the partition assembly 20 is in the blocking state, the partition assembly 20 prevents fluid communication between the second subchamber 144 and the dirt holding chamber 141.

The following embodiments are described by taking the solid-liquid separator 30 to divide the separation chamber 142 into a first sub-chamber 143 and a second sub-chamber 144 as an example.

The solid-liquid separator 30 is disposed in the separation chamber 142, and separates the separation chamber 142 to form a first subchamber 143 and a second subchamber 144. Wherein, the air outlet end of the air inlet duct 13 is communicated with the first subchamber 143, and the second subchamber 144 is positioned at one side of the first subchamber 143 and is in fluid communication with the first subchamber 143.

When the suction assembly works, mixed fluid formed by mixing solid, liquid and gas flows into the first subchamber 143 through the air inlet duct 13 and is separated (the flowing direction of the mixed fluid is indicated by arrows a-b-c in fig. 1). The solid garbage is blocked by the solid-liquid separator 30 and stored in the first subchamber 143, the sewage is separated into the second subchamber 144 by the solid-liquid separator 30, the density of the gas is smaller than that of the solid garbage and the sewage, and the gas can be discharged to the outside through the air outlet 112 (the flowing direction of the gas is indicated by arrows d-e in fig. 1).

When the partition assembly 20 is in the on state, the sewage in the second subchamber 144 can flow into the sewage containing chamber 141 for storage. When the water storage amount of the sewage in the sewage containing cavity 141 reaches the set water storage amount, the partition component 20 is switched to a blocking state to seal the sewage stored in the sewage containing cavity 141, so as to prevent the sewage in the sewage containing cavity 141 from overflowing to the outside through the second subchamber 144, the first subchamber 143 and the air inlet duct 13, or through the second subchamber 144, the first subchamber 143 and the air outlet 112.

Due to the arrangement of the dirt holding cavity 141 and the separating component 20, when the separating component 20 blocks the fluid communication between the second subchamber 144 and the dirt holding cavity 141, the water quantity in the second subchamber 144 is always relatively small, so that excessive sewage can be prevented from flowing and overflowing everywhere in the space when the cleaning equipment is pushed back and forth along the horizontal direction.

In addition, the amount of water that can be moved to the outside by the sewage in the second sub-chamber 144 during the horizontal reciprocation of the cleaning apparatus is correspondingly reduced by the addition of the barrier of the solid-liquid separator 30. In addition, the second sub-chamber 144 is partitioned by the separation chamber 142, and has a smaller volume, so that the space in which sewage in the second sub-chamber 144 can move is limited, and the possibility of overflowing to the outside is further reduced. Therefore, the sewage tank 1 provided in the application can reduce the risk of sewage flowing out to the outside, and is helpful for improving the experience of users.

In addition, in the present application, since the separation chamber 142 is partitioned to form the first sub-chamber 143 and the second sub-chamber 144, the first sub-chamber 143 can be used for storing solid garbage, and the second sub-chamber 144 can be used for storing sewage, so that the water storage capacity of the sewage tank 1 can be improved while the solid-liquid separation can be realized, and the problem that the water storage capacity of the sewage tank 1 is smaller is solved.

Referring to fig. 1 again, and referring to fig. 4 and 5 simultaneously, in some embodiments, the partition assembly 20 includes a partition body 21 and an opening and closing member 22, the partition body 21 is used for partitioning the cavity 14 into a dirt-containing cavity 141 and a separating cavity 142, a communication port is formed on the partition body 21, and the opening and closing member 22 is movably disposed on the partition body 21 and moves relative to the partition body 21 to open or close the communication port; when the opening and closing member 22 opens the communication port, the partition member 20 is switched to the on state, and when the opening and closing member 22 closes the communication port, the partition member 20 is switched to the off state.

The opening degree of the communication port may be 100% when the communication port is opened, or may be less than 100% but greater than 0, and 0 when the communication port is closed.

For example, the shutter 22 may effect closing of the communication port by moving in a direction toward the communication port with respect to the partition main body 21, and effect opening of the communication port by moving in a direction away from the communication port. Alternatively, the direction facing or departing from the communication hole may be a connection line direction of the air inlet 111 and the air outlet 112, or may be a direction perpendicular to the connection line direction of the air inlet 111 and the air outlet 112 (a direction indicated by an arrow Y in fig. 1). Alternatively, the opening and closing member 22 may be rotated with respect to the partition body 21 to open or close the communication port.

The communication port is used for communicating the dirt holding cavity 141 with the second subchamber 144, or is used for communicating the dirt holding cavity 141 with the separation cavity 142. The following embodiments are described by taking the communication port for communicating the dirt holding chamber 141 with the second sub-chamber 144 as an example.

Compared with the situation that the whole separation assembly 20 moves relative to the main body 10 to realize the state switching of the separation assembly 20, the separation main body 21 can always separate the cavity 14 to form the sewage containing cavity 141 and the separating cavity 142 with fixed volumes, so that the structure of the sewage tank 1 is more stable, and the separation main body 21 and the cavity wall of the cavity 14 can be better sealed.

In some embodiments of the present application, the opening and closing member 22 includes an opening and closing portion 221 and an elastic portion 222, where the elastic portion 222 is disposed between the opening and closing portion 221 and the partition body 21; when the pushing force of the sewage in the separation chamber 142 overcomes the elastic pretightening force provided by the elastic portion 222 towards the direction of the communication port, the opening and closing portion 221 opens the communication port.

Specifically, when the pushing force of the sewage in the second subchamber 144 overcomes the elastic pretightening force provided by the elastic part 222 towards the direction of the communication port, the opening and closing part 221 opens the communication port. The elastic portion 222 may be a compression spring, a torsion spring, or other elastic structure. The elastic part 222 is opposite to the communication port by the opening and closing part 221 and applies elastic pretightening force to the opening and closing part 221.

In the present application, the weight of the opening/closing portion 221 is small, and therefore the gravity of the opening/closing portion 221 is omitted for explanation.

Taking fig. 1 and fig. 2 as an example, initially, the opening and closing portion 221 closes the communication port under the action of the elastic pre-tightening force of the elastic portion 222, and then, after the suction assembly works, the sewage in the first subchamber 143 flows into the second subchamber 144 through the solid-liquid separator 30, and is accumulated in the second subchamber 144. When the pushing force of the sewage in the second subchamber 144 is greater than the elastic pre-tightening force provided by the elastic part 222, the opening and closing part 221 is opened, and the sewage in the second subchamber 144 flows into the sewage containing chamber 141.

As the liquid level rises, when the sewage in the sewage containing cavity 141 reaches the set water storage amount, in fig. 1, the set water storage amount in the sewage containing cavity 141 is the maximum water storage amount that can be stored in the sewage containing cavity 141, and in fig. 2, the set water storage amount in the sewage containing cavity 141 may be smaller than the maximum water storage amount or may be equal to the maximum water storage amount, and specifically, may be set according to the size relationship between the volumes of the second sub-cavity 144 and the sewage containing cavity 141. For example, taking the example that the volume of the soil containing cavity 141 is smaller than the volume of the second sub-cavity 144, the set water storage amount may be equal to the maximum water storage amount of the soil containing cavity 141. Taking the example that the volume of the dirt holding chamber 141 is larger than the volume of the second sub-chamber 144, the set water storage amount may be smaller than the maximum water storage amount of the dirt holding chamber 141. When the water storage amount in the sewage containing cavity 141 reaches the set water storage amount, the opening and closing part 221 is closed again under the thrust of the sewage in the sewage containing cavity 141 and the elastic pretightening force of the elastic part 222.

Then, the sewage flowing into the cavity 14 is accumulated in the separation chamber 142 without water inflow into the sewage chamber 141. Taking fig. 1 as an example, the sewage flowing into the separation chamber 142 is accumulated in the first sub-chamber 143 and the second sub-chamber 144 at the same time, and the liquid levels in the first sub-chamber 143 and the second sub-chamber 144 are always level. Taking fig. 2 as an example, the sewage flowing into the separation chamber 142 is filtered into the second sub-chamber 144, and overflows into the first sub-chamber 143 when the water storage amount in the second sub-chamber 144 reaches a certain value.

Taking fig. 3 as an example, initially, the opening and closing portion 221 closes the communication port under the action of the elastic pre-tightening force of the elastic portion 222, and then, when the pushing force of the sewage accumulated in the second subchamber 144 is greater than the elastic pre-tightening force provided by the elastic portion 222, the opening and closing portion 221 is opened, and the sewage in the second subchamber 144 flows into the sewage containing chamber 141.

When the water storage amount in the sewage containing cavity 141 reaches the set water storage amount along with the rising of the liquid level, the opening and closing part 221 closes the communication port under the action of the pushing force of the sewage in the sewage containing cavity 141 and the elastic pretightening force of the elastic part 222. After that, no water is introduced into the sewage containing chamber 141, and sewage is accumulated in the second sub-chamber 144.

It should be noted that, in fig. 3, considering that the sewage in the sewage containing cavity 141 has a pushing force to the opening and closing portion 221, when the liquid surface of the sewage in the sewage containing cavity 141 is not level with the lower surface of the solid-liquid separation member 30, the opening and closing portion 221 closes the communication opening under the pushing force of the sewage in the sewage containing cavity 141 and the elastic pre-tightening force of the elastic portion 222.

In this embodiment, when the sewage in the second subchamber 144 flows into the sewage containing chamber 141 during the operation of the suction assembly, although the sewage in the air inlet duct 13 may flow into the second subchamber 144, if the thrust of the sewage accumulated in the second subchamber 144 is insufficient to overcome the elastic pre-tightening force of the elastic portion 222, the opening and closing portion 221 will close the communication port again until the thrust of the sewage stored in the second subchamber 144 is sufficient to overcome the elastic pre-tightening force of the elastic portion 222. If the output power of the suction assembly is larger, under the thrust action of the sewage continuously flowing in, the opening and closing part 221 may also be kept at the position of opening the communication port all the time after the communication port is opened until the suction assembly is closed or until the opening and closing part 221 is closed under the pretightening force of the elastic part 222 and the thrust action of the sewage in the sewage containing cavity 141.

In this design, the setting of portion 221 and elasticity portion 222 is opened and closed for the portion 221 can overcome the elasticity pretightning force towards the intercommunication mouth direction that elasticity portion 222 provided for it for the thrust of second sub-intracavity 144 interior sewage, and the automatic intercommunication mouth that closes when the suction component stop working, under this kind of setting, open and close piece 22 accessible mechanical design structure opens or closes the intercommunication mouth, and design structure is simpler, and is difficult to break down yet.

In some embodiments, the elastic portion 222 is configured with one end abutting on the partition body 21 and the other end abutting on the torsion spring of the opening and closing portion 221 facing away from the surface of the communication port. The opening and closing portion 221 is rotatably coupled to the partition body 21.

Specifically, the partition assembly 20 further includes a rotating shaft 23, the opening and closing portion 221 is rotationally connected with the partition main body 21 through the rotating shaft 23, the torsion spring has an elastic sleeve and a first end and a second end protruding relatively to the elastic sleeve, the elastic sleeve is sleeved on the rotating shaft 23, the first end of the torsion spring is abutted to the partition main body 21, and the second end of the torsion spring is abutted to the surface of the opening and closing portion 221 opposite to the communication port.

Under this design, if the sewage accumulated in the second subchamber 144 is less and the thrust of the sewage is insufficient to overcome the elastic pretightening force of the elastic portion 222, or if the sewage does not exist in the second subchamber 144, the opening and closing portion 221 will close the communication port again under the action of the elastic pretightening force of the elastic portion 222, so as to reduce the risk of sewage flushing in the sewage containing chamber 141, and further improve the possibility of sewage flushing in the sewage tank 1.

In some embodiments, the volume of the dirt holding chamber 141 is greater than the volume of the separation chamber 142.

Taking fig. 1 and fig. 2 as an example, in such an embodiment, the dirt holding cavity 141 can store more sewage, and when the opening and closing portion 221 closes the communication port, excessive sewage can be prevented from overflowing due to movement when the cleaning device is pushed horizontally and reciprocally, so that better user experience is achieved. Taking fig. 3 as an example, the larger the volume of the sewage containing cavity 141 is, the smaller the volume of the first sub-cavity 143 of the separation cavity 142 is, the smaller the space of the cavity 14 for storing solid garbage is, and the larger the volumes of the second sub-cavity 144 for storing sewage and the sewage containing cavity 141 are, so that the solid-liquid separation can be realized, and the water storage capacity of the sewage tank 1 can be improved.

In some embodiments, the separating element is disposed along a direction perpendicular to the connection line between the air inlet 111 and the air outlet 112, the solid-liquid separating element 30 is located at a side of the separating element facing away from the dirt-containing cavity 141, and the solid-liquid separating element 30 extends along the connection line between the air inlet 111 and the air outlet 112, and separates the separating cavity 142 to form a first sub-cavity 143 and a second sub-cavity 144 located at two sides of the solid-liquid separating element 30. In this embodiment, when the air inlet 111 is located below the air outlet 112, the sewage in the second subchamber 144 can automatically flow into the sewage containing chamber 141 under the action of gravity, and the multiple chambers formed in the sewage tank 1 can be more regular in this way, so as to avoid space waste.

In some embodiments, the tank 1 further comprises a seal 40, the seal 40 being arranged around the circumference of the partition assembly 20 and being used to seal the gap between the partition assembly 20 and the cavity wall of the cavity 14, and between the partition assembly 20 and the outer wall of the air inlet duct 13.

The sealing member 40 may be an elastic rubber ring, an elastic silica gel ring or other structures. Specifically, the seal 40 is used to seal the gap between the partition body 21 and the chamber wall of the cavity 14, and between the partition body 21 and the outer wall of the air inlet duct 13.

Through setting up sealing member 40, then when opening and close portion 221 closed the intercommunication mouth, hold dirty chamber 141 can be independent of outside first sub-chamber 143 and the second sub-chamber 144 to prevent to hold the dirty water drunkenness in the dirty chamber 141 to in first sub-chamber 143 and/or the second sub-chamber 144, thereby can further promote the anti-overflow effect of sewage case 1.

In some embodiments, the sewage tank 1 further includes a detecting member 50, where the detecting member 50 is disposed in the separation chamber 142 and is used for detecting the water storage amount in the separation chamber 142, and when the water storage amount reaches the preset water amount, the detecting member 50 sends out a water amount full signal.

Specifically, the detecting element 50 is disposed in the first subchamber 143 and is configured to detect a water storage amount in the first subchamber 143, and when the water storage amount reaches a preset water amount, the detecting element 50 sends out a full water amount signal.

The sensing element 50 is electrically connected to the control system and transmits signals to the control system. Because the first subchamber 143 is communicated with the air outlet end of the air inlet guide and the air outlet 112, the sewage in the first subchamber 143 is easier to overflow to the outside of the sewage tank 1 than the sewage in the sewage containing chamber 141 and the second subchamber 144. Thus, the water storage in the first subchamber 143 reflects the water storage of the entire cavity 14 and it is indicative of the spill-proof performance of the tank 1.

When the water storage amount in the first subchamber 143 reaches the preset water amount, the detecting member 50 sends a water amount full signal to the control system, and at this time, the control system timely controls the suction assembly to be turned off so as to prevent the excessive water amount in the separation chamber 142 from overflowing to the outside. Meanwhile, an alarm electrically connected with the control system can be further arranged on the sewage tank 1, and when the detection piece 50 sends a water quantity full signal to the control system, the control system also controls the alarm to alarm so as to prompt a user to stop pushing the cleaning equipment to move and clean sewage in the sewage tank 1 in time.

Wherein the preset water amount can be set to be the same or different according to the different upright, leaning and lying modes of the sewage tank 1.

In some embodiments, the tank 1 further includes a drying element 60, the drying element 60 being coupled to the body 10 and being positioned in the flow path of the air flow from the separation chamber 142 out of the cavity 14.

Specifically, the desiccant member 60 is positioned in the flow path of the air stream from the first subchamber 143 out of the cavity 14.

The main body 10 includes a box main body 11 and a bracket 12, wherein the box main body 11 is a hollow structure with two open ends, one open structure forms an air inlet 111, the other open structure forms an air outlet 112, and the bracket 12 is detachably arranged at the air outlet 112. When the bracket 12 is detached from the box main body 11, a user can assemble the partition piece and the solid-liquid separation piece 30 into the box main body 11 conveniently, and when the bracket 12 covers the air inlet 111, the bracket can be enclosed with the box main body 11 to form the cavity 14.

Alternatively, the drying member 60 may be a honeycomb-shaped absorbent paper, a absorbent sponge, or other absorbent structure.

The drying element 60 is disposed on the support 12 and is used for filtering water vapor in the air flow, so as to avoid poor user experience caused by high humidity of the air flow flowing out to the outside.

In some embodiments, the sewage tank 1 further includes a filter element 70, and the main body 10 is provided with an air outlet 112 in communication with the cavity 14, where the filter element 70 is disposed at the air outlet 112.

The filter 70 serves to filter the non-separated micro particulate matters in the air flow so that the air flow discharged from the sewage tank 1 is cleaner, thereby having better user experience.

In some embodiments, the partition, the solid-liquid separator 30 and the bracket 12 are integrally formed, so that the difficulty in assembling the sewage tank 1 can be reduced. The detecting element 50, the drying element 60 and the filtering element 70 are all disposed on the support 12, so that the detecting element 50, the drying element 60, the filtering element 70, the separating element, the solid-liquid separating element 30 and the support 12 can form a whole, and when the separating element and the solid-liquid separating element 30 extend into the cavity 14 and the support 12 is disposed at the air outlet 112, the assembling of the detecting element 50, the drying element 60, the filtering element 70, the separating element, the solid-liquid separating element 30 and the support 12 with the box main body 11 can be realized.

In one embodiment, to ensure that the air flow can pass through the drying member 60 and the filtering member 70 in sequence, a sealing member 80 may be provided for sealing the gap between the inner wall of the box body 11, so as to reduce the possibility of the air flow overflowing from the gap between the box body 11 and the bracket 12.

In the sewage tank 1 provided in the present application, when the partition assembly 20 is in the on state, the sewage in the second subchamber 144 can flow into the sewage containing chamber 141 for storage. When the water storage amount of the sewage in the sewage containing cavity 141 reaches the set water storage amount, the partition assembly 20 is switched to the blocking state to close the sewage stored in the sewage containing cavity 141, so as to prevent the sewage in the sewage containing cavity 141 from overflowing the second subchamber 144 to the outside through the first subchamber 143 from the sewage inlet of the air inlet duct 13 and the air outlet 112 of the main body 10. Due to the arrangement of the dirt holding cavity 141 and the separating component 20, when the separating component 20 blocks the fluid communication between the second subchamber 144 and the dirt holding cavity 141, the water quantity in the second subchamber 144 is always relatively small, so that excessive sewage can be prevented from flowing and overflowing everywhere in the space when the cleaning equipment is pushed back and forth along the horizontal direction. In addition, the amount of water that can be moved to the outside by the sewage in the second sub-chamber 144 during the horizontal reciprocation of the cleaning apparatus is correspondingly reduced by the addition of the barrier of the solid-liquid separator 30. In addition, the second sub-chamber 144 is partitioned by the separation chamber 142, and has a smaller volume, so that the space in which sewage in the second sub-chamber 144 can move is limited, and the possibility of overflowing to the outside is further reduced. Therefore, the sewage tank 1 provided in the application can reduce the risk of sewage flowing out to the outside, and is helpful for improving the experience of users.
