Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning device and a dirt storage component and a cleaning system thereof. Background Art

[0002] A floor scrubber is a type of cleaning equipment suitable for household use, primarily used to clean and wash floor surfaces. It typically features both a water spray and water suction function, automatically spraying water and scrubbing the floor, then sucking the wastewater and remaining dirt into the machine's wastewater tank. Floor scrubbers are easy to use and provide a thorough cleaning effect.

[0003] When using a floor scrubber to clean low areas such as under beds, sofas, tables, and chairs, the user needs to lay the handheld portion of the floor scrubber flat, parallel to the ground, so that the floor scrubber can reach deep into the low area to clean. When the handheld portion of the floor scrubber is flat, the sewage tank also lies flat, which affects the water-gas separation in the sewage tank and easily causes sewage in the sewage tank to flow back into the vacuum motor, shortening the vacuum motor's service life. Utility Model Content

[0004] The present application provides a cleaning device and a dirt storage component and a cleaning system thereof, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake.

[0005] The present application provides a dirt storage assembly for a cleaning device. The cleaning device is used to clean a surface to be cleaned. The dirt storage assembly includes a dirt storage box, which includes a box body and a box cover. The box cover is disposed on the top of the box body. The box cover and the box body are connected to form a dirt storage chamber. The box cover is provided with an air intake port. The air intake port is used to extract gas from the dirt storage chamber to create a negative pressure environment in the dirt storage chamber. The dirt storage assembly also includes a recovery pipe disposed in the dirt storage chamber. The recovery pipe is configured to recover dirt on the surface to be cleaned into the dirt storage chamber under the action of a pressure differential. The recovery pipe extends toward the box cover. The dirt storage assembly also includes a solid-liquid separator. The solid-liquid separator is disposed obliquely in the dirt storage chamber, dividing the dirt storage chamber into a solid dirt storage chamber near the air intake port and a liquid dirt storage chamber away from the air intake port. The solid-liquid separator is provided with one or more first separation holes. The dirt storage assembly also includes a one-way plate, which is rotatably connected to the solid-liquid separator via a rotating shaft to close or open the first separation holes. Among them, the sewage storage component has at least an upright state and a flat state; when the sewage storage component is in the upright state, the box cover and the box body are arranged up and down in sequence, the rotation axis of the one-way plate is located below the first separation hole, and the one-way plate rotates under the action of gravity to open the first separation hole; when the sewage storage component is in the flat state, the box body and the box cover are arranged horizontally adjacent to each other, and the rotation axis of the one-way plate is located above the first separation hole.

[0006] In the current existing technology, the solid-liquid separator is arranged in the sewage storage box, parallel to the cross-section of the sewage storage box, and divides the sewage storage chamber into a solid sewage storage chamber close to the air intake and a liquid sewage storage chamber away from the air intake; the solid-liquid separation plate in the sewage storage box is used to retain the solid waste in the solid sewage storage chamber in the solid sewage storage chamber and allow the liquid to flow into the liquid sewage storage chamber to achieve solid-liquid separation. However, when the sewage storage box is in a flat state, the solid sewage storage chamber and the liquid sewage storage chamber are on the same horizontal plane. During the forward and backward pushing and pulling process, the two can easily flow into each other through the holes on the solid-liquid separation plate, which can easily cause a large amount of sewage in the liquid sewage storage chamber to flow back into the solid sewage storage chamber, so that there is a lot of sewage in the solid sewage storage chamber. At this time, if the sewage storage box is pushed and pulled back and forth, it is easy to cause the sewage in the solid sewage storage chamber to surge to the position of the motor connected to the air intake for suction to form a negative pressure. Therefore, the existing design has a great safety hazard to the negative pressure motor when the sewage storage box is used flat.

[0007] The present application solves the above-mentioned problem through the special arrangement and coordination of the solid-liquid separator and the one-way plate.

[0008] When the sewage storage component is in an upright state or an inclined use state, the one-way plate rotates under the action of its own gravity to open the first separation hole, and the one-way plate remains in a vertical state under the action of its own gravity. Since the solid-liquid separator is tilted in the sewage storage cavity, and the rotation axis of the one-way plate is located below the first separation hole, when the sewage storage component is in an upright state, the angle between the one-way plate and the solid-liquid separator is an obtuse angle, and the bottom of the first separation hole on the solid-liquid separator will not be blocked by the one-way plate. When the upright state is converted to the inclined use state, the one-way plate still remains in a vertical state under the action of its own gravity. In the tilted state, as the solid-liquid separator rotates as a whole, the angle between the one-way plate and the solid-liquid separator slowly changes from an obtuse angle to a right angle. At this time, the area directly below the first separation hole will not be blocked by the one-way plate, and the opening between the one-way plate and the first separation hole will still remain large, which will not affect the downward drainage of the first separation hole. If the solid-liquid separator is not set at an angle, but is parallel to the cross section of the dirt storage box, it is easy to cause the angle between the one-way plate and the solid-liquid separator to be too small in the tilted use state, thereby making the opening between the one-way plate and the first separation hole smaller, resulting in poor drainage of the first separation hole. In addition, the one-way plate is not connected to the solid-liquid separator by a spring, torsion spring, etc. The liquid in the solid dirt storage chamber can smoothly pass through the first separation hole into the liquid dirt storage chamber under the action of its own gravity. In addition, the tilted setting of the solid-liquid separator allows the accumulated liquid in the solid dirt storage chamber to accumulate at the lowest point and flow downward, which results in very little liquid accumulation in the solid dirt storage chamber, thereby improving the solid-liquid separation efficiency.

[0009] When the user needs to use the cleaning device to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage component is in a flat state, and the user pushes forward and pulls back the cleaning device to open or close the first separation hole of the one-way plate; when the one-way plate opens the first separation hole, the liquid in the solid dirt storage chamber can enter the liquid dirt storage chamber through the first separation hole, realizing the recovery of liquid dirt while the surge through the first separation hole is weakened to a certain extent, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake port; and when the sewage in the liquid dirt storage chamber accumulates to a certain height, the one-way plate is hydraulically acted to close the first separation hole in time to prevent the liquid in the liquid dirt storage chamber from flowing back into the solid dirt storage chamber, which can reduce the liquid in the solid dirt storage chamber to further reduce the risk of liquid flowing back into the air intake port; the inclined solid-liquid separation component makes it tend to open the first separation hole at a small angle due to the action of gravity when the one-way plate is in a flat state, so that the liquid in the solid dirt storage chamber can smoothly flush the one-way plate, so that the solid dirt The liquid in the dirty storage chamber enters the liquid dirty storage chamber through the first separation hole; and when the liquid in the liquid dirty storage chamber is about to flow back to the solid dirty storage chamber, it will impact the one-way plate and close the first separation hole, thereby preventing backflow; if the inclined solid-liquid separator is not used, but the solid-liquid separator and the one-way plate are both vertically arranged in the flat state, under the impact of the liquid, it is also necessary to overcome the gravity of the one-way plate, and the flip angle of the one-way plate is limited, which will result in a small opening and closing angle between the one-way plate and the first separation hole, making it easy for some small garbage to accumulate here. Long-term accumulation can easily cause the one-way plate to be unable to completely close the first separation hole, thereby affecting the anti-surge effect; moreover, when the dirt storage component returns from the flat state to the inclined use or upright use state, the one-way plate quickly loses the hydraulic effect of the liquid dirty storage chamber. Under the action of its own gravity and the pressure of the residual liquid in the solid dirty storage chamber, it will quickly open the first separation hole, so that the liquid in the solid dirty storage chamber is quickly separated to the bottom, further ensuring the separation effect in multiple use states and switching processes.

[0010] In one embodiment of the present application, the one-way plate is rotatably connected to a side of the solid-liquid separator facing the liquid dirt storage chamber; the dirt storage chamber of the dirt storage assembly is provided with a first preset liquid storage volume, a second preset liquid storage volume, and a third preset liquid storage volume; the first preset liquid storage volume, the second preset liquid storage volume, and the third preset liquid storage volume decrease in sequence, and the first preset liquid storage volume is a safe liquid storage limit of the dirt storage chamber;

[0011] When the liquid storage volume of the dirt storage chamber is greater than the second preset liquid storage volume and less than the first preset liquid storage volume, and the dirt storage assembly is in a flat state, the one-way plate closes the first separation hole under the hydraulic pressure of the liquid in the liquid dirt storage chamber;

[0012] For example, the second preset liquid storage volume is 70% of the first preset liquid storage volume. At this time, the sewage storage chamber has a large amount of sewage, and most of it is concentrated in the liquid sewage storage chamber. In the flat state, even if the sewage in the liquid sewage storage chamber shakes, due to the large amount of sewage, some of the sewage will continue to be hydraulically pressed on the one-way plate, causing the one-way plate to close the first separation hole.

[0013] And / or, when the liquid storage volume of the dirt storage chamber is less than the second preset liquid storage volume and greater than the third preset liquid storage volume, and the dirt storage assembly is in a lying state, when it moves along the direction of the box body toward the box cover (i.e., the backward pulling direction), the one-way plate closes the first separation hole under the hydraulic action of the liquid in the liquid dirt storage chamber; when it moves along the direction of the box cover toward the box body (i.e., the forward pushing direction), the one-way plate opens the first separation hole under the hydraulic action of the liquid in the solid dirt storage chamber.

[0014] And / or, when the liquid storage volume of the sewage storage chamber is less than the third preset liquid storage volume, and the sewage storage assembly is in a flat state, when the one-way plate moves in the direction of the box cover toward the box body, the one-way plate closes the first separation hole under the inertia of the liquid in the liquid sewage storage chamber; when the one-way plate moves in the direction of the box body toward the box cover, the one-way plate opens the first separation hole under the inertia of the liquid in the solid sewage storage chamber; in this case, the liquid storage volume of the sewage storage chamber is very small. When the liquid storage volume of the sewage storage chamber is less than the third preset liquid storage volume, and the sewage in the sewage storage chamber is distributed to a certain extent in both the liquid sewage storage chamber and the solid sewage storage chamber, the liquid The shaking of sewage in the dirt storage chamber will affect the hydraulic force on the one-way plate; when the dirt storage component stops moving backward, the superimposed inertia of the liquid in the liquid dirt storage chamber continues to pressurize the one-way plate, and overcomes the hydraulic pressure of the solid dirt storage chamber to close the first separation hole, which is beneficial to prevent the liquid in the liquid dirt storage chamber from flowing back to the solid dirt storage chamber; when the dirt storage component stops moving forward, the superimposed inertia of the liquid in the solid dirt storage chamber continues to pressurize the one-way plate, and overcomes the hydraulic pressure of the liquid dirt storage chamber to open the first separation hole and reduce the liquid in the solid dirt storage chamber.

[0015] In one embodiment of the present application, the solid-liquid separator includes a first separation portion and a second separation portion adjacent to each other; when the dirt storage assembly is in a flat position, the first separation portion is closer to the surface to be cleaned relative to the second separation portion, the first separation portion is provided with one or more first separation holes, and the second separation portion is provided with one or more second separation holes; wherein the one-way plate is rotatably connected to the first separation portion; when the dirt storage assembly is in a flat position, the naturally drooping movable end of the one-way plate is close to the inner wall of the box body. In this manner, when the dirt storage assembly is in a flat position, the one-way plate can be easily pushed by the flowing liquid in the liquid dirt storage chamber to close the first separation hole in a timely manner, thereby preventing the liquid in the liquid dirt storage chamber from flowing into the first separation hole from the bottom of the one-way plate and failing to trigger the one-way plate to close the first separation hole in a timely manner.

[0016] In one embodiment of the present application, the solid-liquid separator is arranged obliquely relative to the extension direction of the recovery pipe.

[0017] In one embodiment of the present application, the two opposite ends of the solid-liquid separator are a first end and a second end; when the dirt storage component is in a lying state, the first end is close to the surface to be cleaned relative to the second end; wherein the first end is close to the air intake port relative to the second end.

[0018] Through the above-described method, when the dirt storage assembly is in a flat position, the solid-liquid separator extends away from the box cover and away from the surface to be cleaned. When the user pulls back on the cleaning device, that is, the dirt storage assembly is in a flat position and moves along the box body toward the box cover, at least a portion of the liquid in the solid dirt storage chamber will flow along the solid-liquid separator away from the box cover and away from the surface to be cleaned due to inertia, thereby buffering the surge and extending the flow range of the surge, further weakening the surge and reducing the risk of liquid backflowing into the air intake.

[0019] In one embodiment of the present application, the angle between the solid-liquid separator and the extension direction of the recovery pipe is θ1, satisfying: 40°≤θ1≤60°; the maximum angle between the one-way plate and the solid-liquid separator is θ2, satisfying: 40°≤θ2≤60°.

[0020] In the above manner, by reasonably setting the angle between the solid-liquid separator and the extension direction of the recovery pipe, it is possible to ensure that the solid-liquid separator can weaken the surge and avoid the size of the solid-liquid separator from exceeding the limit.

[0021] In one embodiment of the present application, the solid-liquid separator is provided with a connecting portion and a limiting portion, and the one-way plate is rotatably connected to the connecting portion. The limiting portion is used to abut the one-way plate during the process of the one-way plate rotating in a direction away from the solid-liquid separator to limit further rotation of the one-way plate.

[0022] In one embodiment of the present application, the first separation hole is a strip-shaped hole, and its width is recorded as D1, which satisfies: 3.5 mm≤D1≤5 mm.

[0023] Through the above method, by reasonably setting the width and extension direction of the separation hole, the function of the separation hole to weaken the surge is achieved. The surge is weakened by the separation hole when passing through the separation hole, which can reduce the risk of liquid backflowing into the air intake.

[0024] In one embodiment of the present application, the solid-liquid separator includes: a main body, having a first surface facing away from the air intake port; and a protrusion, connected to the main body, and having a second surface facing away from the air intake port, the second surface being closer to the air intake port relative to the first surface; wherein the one-way plate is arranged opposite to the protrusion.

[0025] Through the above-described method, when the one-way plate closes the first separation hole, the second surface of the protrusion is spaced apart from the one-way plate, thereby reducing the risk of dirt being trapped between the one-way plate and the solid-liquid separator. This prevents the one-way plate from being unable to completely close the first separation hole due to dirt being trapped between the one-way plate and the solid-liquid separator, thereby reducing the risk of liquid in the liquid dirt storage chamber flowing back into the solid dirt storage chamber. This, in turn, reduces the amount of liquid in the solid dirt storage chamber, thereby reducing the risk of liquid backflowing into the air intake.

[0026] In one embodiment of the present application, the main body and the protruding portion are both provided with a first separation hole.

[0027] In one embodiment of the present application, the recovery pipe has a sewage inlet and a sewage outlet at opposite ends respectively; the sewage storage assembly further includes: a partition, which is arranged along the air intake port, and the partition is arranged between the air intake port and the sewage outlet to separate the air intake port and the sewage outlet; and a partition, the partition and the partition are located on both sides of the sewage outlet, the partition is provided with one or more through holes for gas and liquid circulation, and the partition itself or the partition and the sewage storage box together form a separation chamber in the sewage storage chamber; when the sewage storage assembly is in an upright state, the partition and the partition are both located below the box cover; when the sewage storage assembly is in a lying state, the partition and the first separation hole are both located on the side of the sewage storage chamber close to the surface to be cleaned, and the positions of the air intake port, the partition, the sewage outlet and the partition are relatively top to bottom, and the gas and liquid flowing out of the sewage outlet at least partially flow through the separation chamber.

[0028] In the above manner, when the user needs to use the cleaning device to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage component is in a flat state. The user pushes the cleaning device forward and pulls the cleaning device backward, and the liquid in the dirt storage chamber surges back and forth to form a surge. When the sewage tank of a traditional floor scrubber is in a flat state, the surge formed in the sewage tank can easily flow back into the vacuum motor from the air intake. In view of this, the partition of this embodiment is arranged to separate the air intake and the sewage outlet. The dirt flowing out of the sewage outlet will not directly enter the air intake due to the obstruction of the partition, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake. At least part of the gas and liquid in the dirt flowing out of the sewage outlet flows into the separation chamber through the through hole. The surge in the separation chamber is blocked by the partition, which can further reduce the risk of dirt flowing back into the air intake. Since the partition is provided with a through hole for the circulation of gas and liquid, an air flow path connected to the air intake is provided, which is conducive to ensuring the efficiency of forming a negative pressure environment in the dirt storage chamber. That is, the vacuum motor of this embodiment can efficiently make the dirt storage chamber reach a set negative pressure under a certain output power. The through hole of this embodiment also has the function of weakening surge. Even if the liquid in the separation chamber gushes out from the through hole, the surge that gushes out is weakened to a certain extent due to the weakening of the through hole, which can also reduce the risk of liquid backflowing into the air intake. In addition, even if the liquid in the separation chamber gushes out from the through hole, a partition is provided above the partition, which can also block the liquid gushes out of the separation chamber, thereby reducing the risk of dirt backflowing into the air intake.

[0029] In one embodiment of the present application, the partition member includes a first partition portion and a second partition portion that are connected to each other. The dirt storage assembly is in an upright state, the first partition portion is vertically arranged, and its upper and lower directions extend to the box cover and the second partition portion respectively. Both sides of the first partition portion in the horizontal direction extend to the inner side wall of the box body, and both sides of the second partition portion in the horizontal direction extend to the inner side wall of the box body. The first partition portion, the second partition portion, the box cover and the inner side wall of the box body together form a separation chamber; the first partition portion and / or the second partition portion are provided with a through hole.

[0030] In one embodiment of the present application, the first partition portion includes: a flow blocking portion and a vent portion arranged adjacent to each other, the flow blocking portion, one end of which extends to the box cover, and is used to block the liquid surge in the separation chamber; the vent portion, one end of which extends and is connected to the other end of the flow blocking portion, and the other end of which extends to the second partition portion, and the through hole is arranged on the vent portion.

[0031] Through the above method, on the one hand, the vent portion is used to form the above-mentioned first airflow path, thereby improving the airflow efficiency, which is conducive to ensuring the efficiency of forming a negative pressure environment in the dirt storage chamber; on the other hand, the first through hole on the vent portion also plays a role in weakening the surge, and the liquid in the separation chamber flows out from the first through hole. The surge that flows out is weakened to a certain extent by the weakening of the first through hole, which can reduce the risk of liquid backflowing into the air intake.

[0032] In one embodiment of the present application, the partition includes a first partition portion and a second partition portion connected to each other, the first partition portion is arranged around the outer periphery of the sewage outlet and extends to the box cover, and the two sides of the first partition portion respectively extend to the second partition portion and the partition portion to jointly form a guide groove, and the sewage outlet is located at the bottom of the guide groove, and at least part of the gas and liquid output from the sewage outlet enters the separation chamber along the guide groove.

[0033] In the above manner, the first partition and the second partition are arranged to separate the air intake port and the sewage outlet. The dirt flowing out of the sewage outlet will not directly enter the air intake port due to the obstruction of the first partition and the second partition, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake port.

[0034] In one embodiment of the present application, the through holes provided on the partitioning member are distributed on both sides of the recovery pipe.

[0035] In one embodiment of the present application, the first partition is provided with a first through hole; the second partition is provided with a solid dirt storage chamber on a side away from the separation chamber, and the second partition is provided with a second through hole connecting the separation chamber and the solid dirt storage chamber.

[0036] In the above manner, when the user needs to use the cleaning device to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage assembly is in a lying state. The user pushes the cleaning device forward and pulls the cleaning device backward, and the liquid in the dirt storage chamber surges back and forth to form a surge. As the user pushes and pulls the cleaning device forward and backward, the surge in the dirt storage chamber flows repeatedly between the separation chamber and the solid dirt storage chamber through the second through hole. The second through hole of this embodiment has the function of weakening the surge. When the surge passes through the second through hole, the second through hole will weaken the surge, which can reduce the risk of liquid backflowing into the air intake.

[0037] In one embodiment of the present application, the second through holes are a plurality of strip-shaped holes distributed at intervals, and the second through holes extend toward the separator; the width of the second through holes is D2, satisfying: 2mm≤D2≤4mm.

[0038] In the above manner, by reasonably setting the width of the second through hole, the surge weakening function of the second through hole is ensured to be realized, and the surge is weakened by the second through hole when passing through the second through hole, which can reduce the risk of liquid backflowing into the air intake.

[0039] In one embodiment of the present application, the dirt storage component further includes: a liquid-permeable component, which is arranged between the partition component and the solid-liquid separation component; when the dirt storage component is in a lying state, the liquid-permeable component is located on the side of the solid dirt storage chamber close to the surface to be cleaned; and the liquid-permeable component is provided with a liquid-permeable hole.

[0040] Through the above method, when the user needs to clean the dirt storage component, the user lifts the box cover, and the separation structure is separated from the box body together with the box cover. The liquid in the solid dirt storage chamber can flow back into the box body through the liquid permeable hole on the liquid permeable part, reducing the liquid residue in the solid dirt storage chamber, making it easier for the user to clean the dirt storage component.

[0041] Accordingly, the present application also provides a dirt storage assembly for a cleaning device. The cleaning device is used to clean a surface to be cleaned. The dirt storage assembly includes a dirt storage box, which includes a box body and a box cover. The box cover is disposed on the top of the box body. The box cover and the box body are connected to form a dirt storage chamber. The box cover is provided with an air intake port. The air intake port is used to extract gas from the dirt storage chamber to form a negative pressure environment in the dirt storage chamber. The dirt storage assembly also includes a recovery pipe disposed in the dirt storage chamber. The recovery pipe is configured to recover dirt on the surface to be cleaned into the dirt storage chamber under the action of a pressure difference. The recovery pipe extends toward the box cover. The dirt storage assembly also includes a solid-liquid separator disposed in the dirt storage chamber to divide the dirt storage chamber into a solid dirt storage chamber on the side close to the air intake port and a liquid dirt storage chamber on the side away from the air intake port. The solid-liquid separator is provided with a first separation hole for gas-liquid circulation. The dirt storage assembly also includes a one-way plate. The one-way plate is rotatably disposed on the solid-liquid separator to close or open the first separation hole. Among them, the sewage storage component has at least an upright state and a flat state; when the sewage storage component is in the upright state, the box cover and the box body are arranged up and down in sequence, and the one-way plate rotates under the action of gravity to open the first separation hole. When the sewage storage component is in the flat state, the box body and the box cover are arranged horizontally adjacent to each other, and the one-way plate has a tendency to close the first separation hole under the hydraulic action of the liquid in the liquid sewage storage chamber, and the one-way plate has a tendency to open the first separation hole under the hydraulic action of the liquid in the solid sewage storage chamber.

[0042] Through the above method, when the user needs to use the cleaning device to clean low areas such as under beds, sofas, tables and chairs, the dirt storage assembly is in a flat position. The user pushes the cleaning device forward and pulls it back, causing the one-way plate to open or close the first separation hole. Liquid enters the liquid dirt storage chamber through the first separation hole, achieving liquid dirt recovery while also weakening the surge through the first separation hole to a certain extent, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake. In addition, the one-way plate closes the first separation hole, preventing liquid in the liquid dirt storage chamber from flowing back into the solid dirt storage chamber, which can reduce the liquid in the solid dirt storage chamber and further reduce the risk of liquid flowing back into the air intake.

[0043] In one embodiment of the present application, the solid-liquid separator is arranged at an angle relative to the extension direction of the recovery pipe; when the dirt storage assembly is in a lying state and stops moving, the one-way plate rotates under the hydraulic action of the liquid in the liquid dirt storage chamber to close the first separation hole.

[0044] Correspondingly, the present application also provides a dirt storage assembly for a cleaning device. The cleaning device is used to clean a surface to be cleaned. The dirt storage assembly includes a dirt storage box, which includes a box body and a box cover. The box cover is arranged on the top of the box body. The box cover and the box body are connected to form a dirt storage chamber. The box cover is provided with an air intake; the air intake is used to extract the gas in the dirt storage chamber to form a negative pressure environment in the dirt storage chamber. The dirt storage assembly also includes a recovery pipe, which is arranged in the dirt storage chamber. The recovery pipe is configured to recover dirt on the surface to be cleaned into the dirt storage chamber under the action of a pressure difference; the recovery pipe extends toward the box cover. The dirt storage assembly also includes a solid-liquid separator, which is arranged at an angle in the dirt storage chamber, dividing the dirt storage chamber into a solid dirt storage chamber on the side close to the air intake and a liquid dirt storage chamber on the side away from the air intake. The solid-liquid separator includes a first separation portion and a second separation portion. When the dirt storage assembly is in a flat position, the first separation portion is closer to the surface to be cleaned relative to the second separation portion. The first separation portion is provided with one or more first separation holes, and the second separation portion is provided with one or more second separation holes. The dirt storage assembly also includes a one-way plate, which is rotatably connected to the first separation portion and is configured to close or open the first separation hole.

[0045] Through the above method, when the user needs to use the cleaning device to clean low areas such as under beds, sofas, tables and chairs, the dirt storage assembly is in a flat position. The user pushes the cleaning device forward and pulls it back, causing the one-way plate to open or close the first separation hole. Liquid enters the liquid dirt storage chamber through the first separation hole, achieving liquid dirt recovery while also weakening the surge through the first separation hole to a certain extent, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake. In addition, the one-way plate closes the first separation hole, preventing liquid in the liquid dirt storage chamber from flowing back into the solid dirt storage chamber, which can reduce the liquid in the solid dirt storage chamber and further reduce the risk of liquid flowing back into the air intake.

[0046] Furthermore, when the user pulls back on the cleaning device, at least a portion of the liquid in the solid dirt storage chamber flows, under the action of inertia, along the solid-liquid separator in a direction away from the box cover and away from the surface to be cleaned. Once the liquid reaches the area near the second end of the solid-liquid separator, it can flow smoothly into the liquid dirt storage chamber. Specifically, when the liquid reaches the area near the second end of the solid-liquid separator, it flows from the second separation hole of the second separation portion into the liquid dirt storage chamber. This allows for the recovery of liquid dirt while reducing the amount of liquid in the solid dirt storage chamber and also reduces the risk of liquid backflowing into the air intake.

[0047] Correspondingly, the present application also provides a dirt storage assembly of a cleaning device. The cleaning device is used to clean a surface to be cleaned. The dirt storage assembly includes a dirt storage box, which includes a box body and a box cover. The box cover is arranged on the top of the box body. The box cover and the box body are connected to form a dirt storage chamber. The box cover is provided with an air intake port; the air intake port is used to extract the gas in the dirt storage chamber to form a negative pressure environment in the dirt storage chamber. The dirt storage assembly also includes a recovery pipe, which is arranged in the dirt storage chamber. The recovery pipe is configured to recover dirt on the surface to be cleaned into the dirt storage chamber under the action of a pressure difference; the recovery pipe extends toward the box cover. The dirt storage assembly also includes a solid-liquid separator, which is arranged in the dirt storage chamber to divide the dirt storage chamber into a solid dirt storage chamber close to the air intake port and a liquid dirt storage chamber away from the air intake port. The solid-liquid separator is provided with one or more first separation holes. The solid-liquid separator is arranged obliquely relative to the extension direction of the recovery pipe, and the angle between the solid-liquid separator and the extension direction of the recovery pipe is θ1, which satisfies: 40°≤θ1≤60°.

[0048] Through the above-described method, when the dirt storage assembly is in a flat position, the solid-liquid separator extends away from the box cover and away from the surface to be cleaned. When the user pulls back on the cleaning device, that is, the dirt storage assembly is in a flat position and moves along the box body toward the box cover, at least a portion of the liquid in the solid dirt storage chamber will flow along the solid-liquid separator away from the box cover and away from the surface to be cleaned due to inertia, thereby buffering the surge and extending the flow range of the surge, further weakening the surge and reducing the risk of liquid backflowing into the air intake. The angle setting of the solid-liquid separator is a comprehensive consideration of the tilted usage state and the anti-surge effect. When the user tilts it to use, it is more convenient for the body assembly to be at 30°~50° with the surface to be cleaned, and the dirt storage assembly rotates with the body assembly. Due to the pre-tilted setting, the solid-liquid separator can basically maintain a horizontal position when the dirt storage assembly is used in normal tilted state. The angle with the one-way plate can be kept large, which helps the liquid above to flow smoothly downward. Moreover, when lying flat, the tilted setting of the solid-liquid separator helps the liquid above it to move along the solid-liquid separator to release kinetic energy, and helps the liquid flipped up below it to be blocked by the solid-liquid separator, thereby weakening the surge phenomenon in the dirt storage chamber.

[0049] Furthermore, by reasonably setting the angle between the solid-liquid separator and the extension direction of the recovery pipe, it is possible to ensure that the solid-liquid separator can weaken the surge while preventing the size of the solid-liquid separator from exceeding the limit.

[0050] In one embodiment of the present application, the two opposite ends of the solid-liquid separator are a first end and a second end; when the dirt storage component is in a lying state, the first end is close to the surface to be cleaned relative to the second end; wherein the first end is close to the air intake port relative to the second end.

[0051] Correspondingly, the present application also provides a cleaning device, comprising: a main body, provided with a dirt storage component as described in the above embodiment; and a floor brush, rotatably connected to the main body, and used to clean the surface to be cleaned.

[0052] Accordingly, the present application also provides a cleaning system, comprising: a cleaning device as described in the above embodiment; and a base station for charging the cleaning device.

[0053] The beneficial effects of the present application are as follows: the present application provides a cleaning device and its dirt storage component, and a cleaning system. When the user needs to use the cleaning device to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage component is in a lying state. The user pushes the cleaning device forward and pulls the cleaning device backward to open or close the first separation hole on the one-way plate, and the liquid enters the liquid dirt storage chamber through the first separation hole, thereby realizing liquid dirt recovery while the surge passing through the first separation hole is weakened to a certain extent, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake. In addition, the one-way plate closes the first separation hole to prevent the liquid in the liquid dirt storage chamber from flowing back into the solid dirt storage chamber, which can reduce the liquid in the solid dirt storage chamber to further reduce the risk of liquid flowing back into the air intake.

[0054] Furthermore, when the sewage storage assembly is in an upright or tilted position, the one-way plate rotates under its own weight to open the first separation hole. When the sewage storage assembly is in an upright or tilted position, the one-way plate maintains the first separation hole open under its own weight, and the one-way plate is not connected to the solid-liquid separator via a spring, torsion spring, or other means. Thus, when the sewage storage assembly is in a flat position and moves backward, the liquid in the solid sewage storage chamber more easily drives the one-way plate to rotate away from the solid-liquid separator to open the first separation hole, thereby ensuring the surge reduction function is achieved. When the sewage storage assembly moves forward, the liquid in the liquid sewage storage chamber also more easily drives the one-way plate toward the solid-liquid separator to close the first separation hole, thereby preventing the liquid in the liquid sewage storage chamber from flowing back into the solid sewage storage chamber. Moreover, when the dirt storage assembly is in an upright or tilted state, the one-way plate keeps the first separation hole open, and the dirt enters the solid dirt storage chamber under the action of its own gravity, and the liquid dirt enters the liquid dirt storage chamber under the separation of the solid-liquid separator.

[0082] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "up", "down", "left", and "right", generally refer to the up, down, left, and right of the device in actual use or working state, specifically the drawing direction in the accompanying drawings.

[0083] In this application, unless otherwise specified or limited, terms such as "connected," "connected," and "stacked" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0084] The present application provides a cleaning device and its dirt storage component, and a cleaning system, which are described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own focus. For parts not detailed in one embodiment, please refer to the relevant description of other embodiments.

[0085] See also Figures 1 to 3 , Figure 1 This is a schematic structural diagram of an embodiment of the cleaning device of the present application. Figure 2 yes Figure 1 The schematic diagram of the structure of the dirt storage component of the cleaning device shown is in a tilted use state, Figure 3 yes Figure 1 The diagram shows the structure of the dirt storage component of the cleaning device in a lying state.

[0086] In one embodiment, the cleaning system includes a cleaning device 30. The cleaning device 30 is used to clean the surface 20 to be cleaned. The cleaning device 30 can be a cleaning device such as a floor scrubber. A user pushes the cleaning device 30 to move across the surface 20 to be cleaned, and the cleaning device 30 cleans the area it passes over. Figure 2 and Figure 3 The direction indicated by the arrow P is the forward direction of the cleaning device 30 , and the opposite direction of the direction indicated by the arrow P is the backward direction of the cleaning device 30 .

[0087] Of course, the cleaning device 30 can also be a cleaning robot or other cleaning equipment. The cleaning device 30 can automatically move across the surface to be cleaned 20 to clean the area it passes over. The surface to be cleaned 20 can be the ground, or the surface of an object to be cleaned, etc., without limitation. The embodiments of this application use a floor scrubber as an example for illustrative purposes only and do not limit the form of the cleaning device 30.

[0088] The cleaning system further includes a base station, which is matched with the cleaning device 30 and can be used to charge the cleaning device 30 or to store the cleaning device 30 .

[0089] In one embodiment, the cleaning device 30 includes a main unit 31 and a floor brush 32 rotatably connected to the main unit 31. The floor brush 32 is used to clean the surface to be cleaned 20. The user holds the main unit 31 and pushes the floor brush 32 to move across the surface to be cleaned 20. The floor brush 32 can clean the area it passes through.

[0090] The cleaning device 30 also includes a dirt storage assembly 10, which is mounted on the main body 31 and is used to store dirt absorbed by the cleaning device 30 from the surface 20 to be cleaned. As the floor brush 32 cleans the surface 20, it absorbs dirt, including both solid and liquid dirt. The dirt absorbed by the floor brush 32 is stored in the dirt storage assembly 10.

[0091] The sewage storage assembly 10 according to the embodiment of the present application is described below.

[0092] Please also refer to Figures 4a to 8 , Figure 4a-4b This is a structural diagram of an embodiment of the sewage storage component of the present application. Figure 5 yes Figure 4a-4b The exploded structure diagram of the sewage storage assembly is shown in FIG. Figure 6 yes Figure 4a-4b The schematic diagram of the top view of the sewage storage component is shown in FIG. Figure 7 yes Figure 6 The cross-sectional structure diagram of the sewage storage component in the AA direction is shown. Figure 8 yes Figure 6 The cross-sectional structure diagram of the sewage storage component in the BB direction is shown.

[0093] In one embodiment, the dirt storage assembly 10 includes a dirt storage tank 11, which is used to store dirt absorbed by the cleaning device 30 from the surface to be cleaned 20. Specifically, the dirt storage tank 11 includes a housing 113 and a lid 114. The lid 114 is mounted on top of the housing 113. The lid 114 and the housing 113 are connected to form a dirt storage chamber 111, which is used to store dirt absorbed by the cleaning device 30 from the surface to be cleaned 20. The lid 114 is provided with an air intake 112, which is used to extract air from the dirt storage chamber 111 to create a negative pressure environment therein.

[0094] The dirt storage assembly 10 also includes a recovery pipe 12. The recovery pipe 12 is arranged in the dirt storage chamber 111, and the recovery pipe 12 extends toward the box cover 114. The recovery pipe 12 is configured to be able to recover the dirt on the surface to be cleaned 20 into the dirt storage chamber 111 under the action of pressure difference. Specifically, the recovery pipe 12 is connected to the bottom of the box body 113. The dirt storage assembly 10 has a first direction Z, and the recovery pipe 12 extends along the first direction Z. The opposite ends of the recovery pipe 12 respectively have a dirt inlet 121 and a dirt outlet 122. Under the action of pressure difference, the dirt on the surface to be cleaned 20 enters the recovery pipe 12 from the dirt inlet 121 and is recovered to the dirt storage chamber 111 through the dirt outlet 122. The main unit 31 is also provided with a vacuum motor, which extracts the gas in the dirt storage chamber 111 through the air intake 112 to form a negative pressure environment in the dirt storage chamber 111. Due to the pressure difference between the inside and outside of the dirt storage chamber 111 , dirt on the surface to be cleaned 20 enters the recovery pipe 12 from the dirt inlet 121 and is recovered into the dirt storage chamber 111 through the dirt outlet 122 .

[0095] Furthermore, the recovery pipe 12 includes a first pipe section 123 and a second pipe section 124. The first pipe section 123 is disposed on the box body 113, and the second pipe section 124 is disposed on the box cover 114. When the box cover 114 is closed on the top of the box body 113, the first pipe section 123 and the second pipe section 124 are spliced together to form a complete recovery pipe 12. Of course, in other embodiments of the present application, the recovery pipe 12 is not limited to a segmented design and can be a single-piece pipe structure, which is not limited here.

[0096] It should be noted that the dirt storage assembly 10 has at least an upright state, a tilted use state, and a lying state. Figure 1 The sewage storage assembly 10 is in an upright state. Figure 2 The sewage storage component 10 is in a tilted state of use. Figure 3 The dirt storage assembly 10 is in a flat state. The angles between the first direction Z of the dirt storage assembly 10 and the surface to be cleaned 20 in the upright state, the angles between the first direction Z of the dirt storage assembly 10 and the surface to be cleaned 20 in the tilted state, and the angles between the first direction Z of the dirt storage assembly 10 and the surface to be cleaned 20 in the flat state decrease in sequence.

[0097] like Figure 1 As shown, when the user is not using the cleaning device 30, the main body 31 of the cleaning device 30 is in an upright state as a whole, that is, the dirt storage component 10 is in an upright state at this time. Figure 2 As shown, when the user normally uses the cleaning device 30 to clean the surface 20 to be cleaned, the main body 31 is in a tilted state as a whole, that is, the dirt storage component 10 is in a tilted use state at this time, and the user controls the cleaning device 30 to move forward and backward (that is, the cleaning device 30 moves in the direction indicated by the arrow P and the opposite direction). Figure 3As shown, when a user needs to use the cleaning device 30 to clean low areas such as under beds, sofas, tables, and chairs, the user lays the main unit 31 flat so that it is approximately parallel to the surface to be cleaned 20. At this time, the dirt storage assembly 10 is in a flat position, allowing the cleaning device 30 to reach deep into the low area for cleaning. When the dirt storage assembly 10 is in a flat position, the first direction Z of the dirt storage assembly 10 can be parallel to the surface to be cleaned 20, which facilitates the cleaning device 30 to reach deep into the low area for cleaning.

[0098] Please also refer to Figures 9 to 11 , Figure 9 yes Figure 7 The schematic diagram of the structure of the sewage storage component is in a flat state. Figure 10 This is a structural diagram of an embodiment of the box cover and separation structure of the present application. Figure 11 yes Figure 10 The side view of the box cover and the separation structure is shown.

[0099] In one embodiment, the dirt storage assembly 10 further includes a separation structure 10a, which is connected to the box cover 114. The separation structure 10a includes a partition 14. The partition 14 is disposed along the air intake 112 and between the air intake 112 and the dirt outlet 122 to separate the air intake 112 and the dirt outlet 122. This prevents dirt flowing out of the dirt outlet 122 from directly entering the air intake 112 due to the barrier provided by the partition 14. This reduces the risk of dirt flowing back into the vacuum motor through the air intake 112, thereby preventing the vacuum motor from being affected by the barrier.

[0100] The separation structure 10a includes a partition 13. The partition 13 and the partition 14 are located on both sides of the sewage outlet 122. When the sewage storage component 10 is in an upright state, the partition 14 and the partition 13 are both located below the box cover 114. When the sewage storage component 10 is in a lying state, the positions of the air intake 112, the partition 14, the sewage outlet 122 and the partition 13 are relatively top-down. Specifically, the sewage storage component 10 also has a second direction X perpendicular to the first direction Z. When the sewage storage component 10 is in a lying state, the second direction X is perpendicular to the surface to be cleaned 20. The partition 13 and the partition 14 are located on both sides of the sewage outlet 122 in the second direction X, while the air intake 112 is located on the side of the partition 14 facing away from the partition 13 in the second direction X. When the sewage storage component 10 is in a lying state, the air intake 112, the partition 14, the sewage outlet 122 and the partition 13 are distributed from top to bottom along the second direction X.

[0101] The partition 13 itself or the partition 13 and the dirt storage box 11 together form a separation chamber 131 in the dirt storage chamber 111. The embodiment of the present application is described by taking the partition 13 and the dirt storage box 11 together to form the separation chamber 131 in the dirt storage chamber 111 as an example. This is only for discussion purposes and does not constitute a limitation. The partition 13 is provided with one or more through holes 1341 for gas and liquid circulation. The gas, liquid and solid dirt output from the outlet 122 are blocked by the partition 14 and the box cover 114. At least part of the gas and liquid output from the outlet 122 flows into the separation chamber 131, and at least part of the solid dirt output from the outlet 122 is blocked outside the separation chamber 131. The gas and liquid flowing out of the outlet 122 at least partially flow through the separation chamber 131, that is, flow through the separation chamber 131 through the through holes 1341 on the partition 13. Among the dirt flowing out of the dirt outlet 122 , at least part of the gas and liquid flows into the separation chamber 131 through the through hole 1341 , while at least part of the solid dirt is blocked outside the separation chamber 131 by the partition 13 .

[0102] When the user needs to use the cleaning device 30 to clean low areas such as under beds, sofas, tables and chairs, the dirt storage assembly 10 is in a flat position. When the user pushes and pulls the cleaning device 30 forward and backward, the liquid in the dirt storage chamber 111 surges back and forth, forming a surge. When the sewage tank of a traditional floor scrubber is in a flat position, the surge formed in the sewage tank can easily flow back into the vacuum motor from the air intake 112. In view of this, the partition 14 of this embodiment is provided to separate the air intake 112 and the sewage outlet 122. The dirt flowing out of the sewage outlet 122 will not directly enter the air intake 112 due to the obstruction of the partition 14, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake 112. At least part of the gas and liquid in the dirt flowing out of the sewage outlet 122 flows into the separation chamber 131 through the through hole 1341. The surge in the separation chamber 131 is blocked by the partition 13, which can further reduce the risk of dirt flowing back into the air intake 112. Since the partition 13 is provided with a through hole 1341 for the circulation of gas and liquid, an air flow path connecting to the air intake 112 is provided, which is conducive to ensuring the efficiency of forming a negative pressure environment in the dirt storage chamber 111. That is, the vacuum motor of this embodiment can efficiently make the dirt storage chamber 111 reach a set negative pressure under a certain output power. The through hole 1341 of this embodiment also has the function of weakening surge. Even if the liquid in the separation chamber 131 flows out of the through hole 1341, the surge that flows out is weakened to a certain extent due to the weakening of the through hole 1341, which can also reduce the risk of liquid backflowing into the air intake 112. In addition, even if the liquid in the separation chamber 131 flows out of the through hole 1341, a partition 14 is also provided above the partition 13. The partition 14 can also block the liquid flowing out of the separation chamber 131, thereby reducing the risk of dirt backflowing into the air intake 112.

[0103] When the sewage tank of a conventional floor scrubber is in a horizontal position, to prevent sewage from backflowing into the air intake 112, the suction force of the vacuum motor is typically reduced. This inevitably reduces the efficiency of dirt recovery, significantly compromising the cleaning performance of the conventional floor scrubber. This embodiment significantly reduces the risk of dirt backflowing into the air intake 112 by providing a partition 13 and a divider 14. Therefore, when the sewage storage assembly 10 is in a horizontal position, this embodiment can control the vacuum motor to output a higher suction force to ensure efficient dirt recovery. This embodiment may even eliminate the need to reduce the suction force of the vacuum motor. This shows that the sewage storage assembly 10 of this embodiment still maintains good dirt recovery efficiency when in a horizontal position, ensuring the cleaning performance of the cleaning device 30, while also reducing the risk of damage to the vacuum motor. Furthermore, when the sewage tank of a conventional floor scrubber is in a horizontal position, the amount of liquid stored in the sewage tank must be strictly controlled, typically at a low level, to prevent sewage from backflowing into the air intake 112. This increases the frequency of sewage tank cleaning for the user, significantly increasing the user's workload. In this embodiment, since the risk of dirt flowing back into the air inlet 112 is low, the dirt storage component 10 is allowed to have a larger liquid storage capacity in the lying state, thereby reducing the frequency of the user cleaning the dirt storage component 10 and alleviating the user's usage burden.

[0104] In one embodiment, the through holes 1341 provided on the partition member 13 are distributed on both sides of the recovery pipe 12. Specifically, the sewage storage assembly 10 further defines a third direction Y, and the first direction Z, the second direction X, and the third direction Y are mutually perpendicular. The partition member 13 is provided on both sides of the recovery pipe 12 in the third direction Y, and the through holes 1341 are provided on both sides of the partition member 13 in the third direction Y.

[0105] The gas flowing out of the sewage outlet 122 enters the separation chamber 131 from the through hole 1341 on one side of the recovery pipe 12, and the gas in the separation chamber 131 flows out of the separation chamber 131 from the through hole 1341 on the other side of the recovery pipe 12, and the gas flowing out of the separation chamber 131 flows to the air intake port 112, forming a first airflow path.

[0106] Furthermore, the gas flowing out of the sewage outlet 122 also flows in a direction away from the box cover 114, flowing to the side of the partition member 13 away from the box cover 114. The gas flows from one side of the recovery pipe 12 in the third direction Y and along the outer periphery of the recovery pipe 12 to the other side of the recovery pipe 12 in the third direction Y, and then flows to the air intake 112, forming a second airflow path. This embodiment improves the efficiency of airflow through the coordination of the first and second airflow paths, further facilitating the efficient formation of a negative pressure environment in the sewage storage chamber 111.

[0107] In addition, a solid dirt storage chamber 1111 is formed on the side of the partition 13 away from the box cover 114. The solid dirt storage chamber 1111 is used to store solid dirt, and the second air flow path passes through the solid dirt storage chamber 1111. When the solid dirt storage chamber 1111 is full of solid dirt, the solid dirt may block the second air flow path. This embodiment provides a first air flow path, which can provide an unobstructed air flow path when the second air flow path is blocked, ensuring that the dirt storage component 10 can normally recover the dirt on the surface to be cleaned 20. The through hole 1341 provided on the partition 13 can separate the gas, liquid and solid dirt output from the outlet 122, reduce the risk of the first air flow path being blocked by solid dirt, and the solid dirt output from the outlet 122 is moved to the solid dirt storage chamber 1111 for storage.

[0108] In one embodiment, the partition 14 includes a first partition portion 141 and a second partition portion 142. The first partition portion 141 is disposed around the periphery of the sewage outlet 122 and extends to the chamber cover 114. Both sides of the first partition portion 141 extend to the second partition portion 142 and the partition member 13, respectively, to form a guide groove 115. The sewage outlet 122 is located at the bottom of the guide groove 115. At least a portion of the gas and liquid output from the sewage outlet 122 flows along the guide groove 115 into the separation chamber 131.

[0109] The first partition 141 and the second partition 142 are arranged to separate the air intake port 112 and the sewage outlet 122. The dirt flowing out of the sewage outlet 122 will not directly enter the air intake port 112 due to the obstruction of the first partition 141 and the second partition 142, which can reduce the risk of dirt flowing back into the vacuum motor through the air intake port 112.

[0110] The second partition 142 and the partition member 13 are located on either side of the first partition 141 in the second direction X. That is, when the sewage storage assembly 10 is in a flat position, the second partition 142, the first partition 141, and the partition member 13 are positioned from top to bottom along the second direction X. The first partition 141, the second partition 142, and the partition member 13 cooperate to enclose a diversion groove 115. Dirt discharged from the sewage outlet 122 enters the diversion groove 115. The gas and liquid discharged from the sewage outlet 122, guided by the diversion groove 115, flow into the separation chamber 131 through the through-holes 1341 in the partition member 13.

[0111] Furthermore, the air intake port 112 is in the shape of an elongated strip and extends along the third direction Y. The second partition 142 is located on one side of the first partition 141 in the direction in which the air intake port 112 extends, specifically, the second partition 142 is located on one side of the first partition 141 in the third direction Y. The guide groove 115 is located on one side of the recovery pipe 12 in the direction in which the air intake port 112 extends. The gas flowing out of the sewage outlet 122 enters the separation chamber 131 through the through hole 1341 on the side where the guide groove 115 is located. The gas in the separation chamber 131 flows out of the separation chamber 131 through the through hole 1341 on the side of the recovery pipe 12 away from the guide groove 115, and then flows to the air intake port 112.

[0112] Of course, in other embodiments of the present application, the second partition 142 is not limited to being located on one side of the first partition 141. It can be that both ends of the partition 14 extend along the extension direction of the air inlet 112 to the inner sidewall of the box body 113. In this case, the second partition 142 is distributed on both sides of the recovery pipe 12. The second partitions 142 on both sides of the recovery pipe 12 can maximize the resistance to surges and further reduce the risk of dirt flowing back into the air inlet 112.

[0113] Moreover, the partition 13 is not limited to being distributed on both sides of the recovery pipe 12. For example, based on the fact that the second partition 142 is located on the side of the first partition 141 in the extension direction of the air intake port 112, the partition 13 can be only arranged on the side of the recovery pipe 12 away from the second partition 142 in the extension direction of the air intake port 112. At this time, the second partition 142 and the partition 13 are respectively used to block the surges on both sides of the recovery pipe 12, thereby reducing the risk of dirt flowing back into the air intake port 112.

[0114] In one embodiment, the dirt storage assembly 10 further includes a fifth seal 195. The fifth seal 195 is disposed on the side of the second partition 142 away from the first partition 141 and on the side of the second partition 142 away from the lid 114. The fifth seal 195 forms a seal between the second partition 142 and the inner wall of the housing 113. This prevents dirt from bypassing the second partition 142 and directly entering the air intake 112, further reducing the risk of dirt backflowing into the air intake 112.

[0115] In one embodiment, the partition member 13 includes a first partition portion 13a and a second partition portion 13b that are connected. When the sewage storage assembly 10 is in an upright position, the first partition portion 13a is vertically arranged, extending vertically to the box cover 114 and the second partition portion 13b, respectively. Both sides of the first partition portion 13a extend horizontally to the inner sidewalls of the box body 113, and both sides of the second partition portion 13b extend horizontally to the inner sidewalls of the box body 113. The first partition portion 13a, the second partition portion 13b, the box cover 114, and the inner sidewalls of the box body 113 collectively form a separation chamber 131. The first partition portion 13a and / or the second partition portion 13b are provided with a through hole 1341.

[0116] The first partition 13a includes a flow blocker 133 and a vent 134, which are adjacent to each other. One end of the flow blocker 133 extends to the chamber cover 114 and is used to block liquid surges in the separation chamber 131. One end of the vent 134 connects to the other end of the flow blocker 133, and the other end of the vent 134 extends to the second partition 13b. The through hole 1341 of the first partition 13a is arranged on the vent 134.

[0117] When the sewage storage assembly 10 is in an upright position, the baffle 133 and the vent 134 are positioned from top to bottom, specifically, along the first direction Z. When the sewage storage assembly 10 is in a flat position, the baffle 133 and the vent 134 are positioned parallel to the surface to be cleaned 20. The baffle 133 is closer to the cover 114 than the vent 134, thus preventing liquid surges in the separation chamber 131. The through hole 1341 of the first partition 13a is a first through hole 1341a, which is specifically located in the vent 134. The gas flowing out of the sewage outlet 122 enters the separation chamber 131 through the first through-hole 1341a of the vent portion 134 on one side of the recovery pipe 12, and the gas in the separation chamber 131 flows out of the separation chamber 131 through the first through-hole 1341a of the vent portion 134 on the other side of the recovery pipe 12. On the one hand, the vent portion 134 is used to form the above-mentioned first airflow path, improving the efficiency of airflow flow, which is conducive to ensuring the efficiency of forming a negative pressure environment in the sewage storage chamber 111. On the other hand, the first through-hole 1341a on the vent portion 134 also plays a role in weakening surges. The liquid in the separation chamber 131 surges out through the first through-hole 1341a. Under the weakening of the first through-hole 1341a, the surge is weakened to a certain extent, which can reduce the risk of liquid backflowing into the air intake 112.

[0118] Furthermore, along the extension direction of the recovery pipe 12, the length of the partition 13 is denoted as H, and the length of the flow blocking portion 133 is denoted as h, which satisfies: 0.2≤h / H≤0.5. That is, in the first direction Z, the length H of the partition 13 and the length h of the flow blocking portion 133 satisfy: 0.2≤h / H≤0.5. In this way, by reasonably setting the relationship between the length of the partition 13 and the length of the flow blocking portion 133, this embodiment can ensure that the flow blocking portion 133 plays a sufficient role in blocking surges and reducing the risk of liquid backflowing into the air intake 112, while also ensuring the airflow efficiency of the airflow path (i.e., the first airflow path) provided by the vent 134, and ensuring the efficiency of forming a negative pressure environment in the sewage storage chamber 111.

[0119] Furthermore, the total flow area of the through hole 1341 is S1, which satisfies: 300mm 2 ≤S1≤500mm 2 , the flow area of a single through hole 1341 is 30mm 2 ~60mm 2 , the negative pressure at the air inlet 112 is 15kPa to 25kPa. In this embodiment, the total flow area of the through holes 1341, the flow area of a single through hole 1341, and the negative pressure at the air inlet 112 cooperate with each other to ensure the efficiency of airflow, and thus ensure the efficiency of forming a negative pressure environment in the dirt storage chamber 111. If the total flow area of the through holes 1341 and / or the flow area of a single through hole 1341 are too large or too small, the flow capacity provided by the through holes 1341 is not compatible with the negative pressure at the air inlet 112 (i.e., the suction force of the vacuum motor), which will result in a low efficiency in forming a negative pressure environment in the dirt storage chamber 111 and cause waste of power consumption of the vacuum motor.

[0120] In one embodiment, a solid dirt storage chamber 1111 is formed on a side of the second partition portion 13b away from the separation chamber 131. A second through hole 1341b is formed in the second partition portion 13b to connect the separation chamber 131 and the solid dirt storage chamber 1111.

[0121] When the user needs to use the cleaning device 30 to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage assembly 10 is in a lying state. The user pushes and pulls the cleaning device 30 forward and backward, and the liquid in the dirt storage chamber 111 surges back and forth to form a surge. As the user pushes and pulls the cleaning device 30 forward and backward, the surge in the dirt storage chamber 111 flows repeatedly between the separation chamber 131 and the solid dirt storage chamber 1111 through the second through hole 1341b. The second through hole 1341b of this embodiment has the function of weakening the surge. When the surge passes through the second through hole 1341b, the second through hole 1341b will weaken the surge, which can reduce the risk of liquid backflowing into the air intake 112.

[0122] Furthermore, the second through holes 1341b are a plurality of strip-shaped holes spaced apart from each other. Specifically, the plurality of second through holes 1341b may be spaced apart along the extension direction of the air intake 112. The second through holes 1341b extend toward the partition 14, i.e., the extension direction of the second through holes 1341b is parallel to the second direction X. The second through holes 1341b are elongated holes. This embodiment ensures that the surge-weakening function of the second through holes 1341b is achieved by rationally setting the extension direction of the second through holes 1341b. When the surge passes through the second through holes 1341b, it is weakened by the second through holes 1341b, thereby reducing the risk of liquid backflowing into the air intake 112.

[0123] Further, if Figure 12 As shown, the width of the second through hole 1341b is D2, satisfying the following: 2mm≤D2≤4mm. The width of the second through hole 1341b should be understood as the dimension of the second through hole 1341b in the third direction Y. This embodiment ensures that the surge-weakening function of the second through hole 1341b is achieved by rationally setting the width of the second through hole 1341b. The surge is weakened by the second through hole 1341b when passing through it, thereby reducing the risk of liquid backflow into the air intake 112.

[0124] Please also refer to Figure 13 and Figure 14 , Figure 13 yes Figure 9 The schematic diagram of the structure of the sewage storage assembly when it moves backward is shown. Figure 14 yes Figure 9 Schematic diagram of the structure of the sewage storage assembly when moving forward.

[0125] In one embodiment, the separation structure 10a further includes a solid-liquid separator 16. The solid-liquid separator 16 is disposed on the side of the partition member 13 that is distal to the air inlet 112 in the direction in which the recovery pipe 12 extends. The solid-liquid separator 16 divides the dirt storage chamber 111 into a solid dirt storage chamber 1111 on the side near the air inlet 112 and a liquid dirt storage chamber 1112 on the side distal to the air inlet 112. The solid-liquid separator 16 is provided with one or more separation holes (including the first separation hole 161 and the second separation hole 168 described below) to facilitate gas-liquid circulation.

[0126] Specifically, the solid-liquid separator 16 includes an adjacent first separation portion 16c and a second separation portion 16d; when the dirt storage assembly 10 is in a lying state, the first separation portion 16c is close to the surface to be cleaned 20 relative to the second separation portion 16d, and the first separation portion 16c is provided with one or more first separation holes 161, and the second separation portion 16d is provided with one or more second separation holes 168.

[0127] When the dirt storage assembly 10 is in an upright position, the separation chamber 131, the solid dirt storage chamber 1111, and the liquid dirt storage chamber 1112 are arranged from top to bottom, i.e., the separation chamber 131, the solid dirt storage chamber 1111, and the liquid dirt storage chamber 1112 are sequentially arranged in a direction away from the cover 114. When the dirt storage assembly 10 is in a flat position, the separation chamber 131, the solid dirt storage chamber 1111, and the liquid dirt storage chamber 1112 are arranged parallel to the surface to be cleaned 20. The solid and liquid dirt discharged from the dirt outlet 122 are transferred together to the solid dirt storage chamber 1111. After separation by the solid-liquid separator 16, most of the liquid dirt moves through the separation hole to the liquid dirt storage chamber 1112 for storage, while the majority of the solid dirt remains in the solid dirt storage chamber 1111.

[0128] When the user needs to use the cleaning device 30 to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage assembly 10 is in a lying state. The user pushes and pulls the cleaning device 30 forward and backward, and the liquid in the dirt storage chamber 111 surges back and forth to form a surge. As the user pushes and pulls the cleaning device 30 forward and backward, the surge in the dirt storage chamber 111 flows repeatedly between the solid dirt storage chamber 1111 and the liquid dirt storage chamber 1112 through the separation hole. The separation hole of this embodiment has the function of weakening the surge. When the surge passes through the separation hole, the separation hole will weaken the surge, which can reduce the risk of liquid backflowing into the air intake 112.

[0129] Furthermore, Figure 15 Taking the second separation hole 168 as an example, the separation hole is a strip-shaped hole with a width denoted as D1, which satisfies the following conditions: 3.5 mm ≤ D1 ≤ 5 mm. The width of the separation hole should be understood as the dimension of the separation hole in the third direction Y. In addition, the separation hole extends along the second direction X or extends obliquely along the second direction X. This embodiment ensures that the separation hole's surge weakening function is achieved by reasonably setting the width and extension direction of the separation hole. When the surge passes through the separation hole, it is weakened by the separation hole, which can reduce the risk of liquid backflowing into the air intake 112.

[0130] In one embodiment, the solid-liquid separator 16 is arranged obliquely relative to the extension direction of the recovery pipe 12. Specifically, the opposite ends of the solid-liquid separator 16 are respectively a first end 16a and a second end 16b. When the dirt storage assembly 10 is in a flat state, the first end 16a is closer to the surface to be cleaned 20 relative to the second end 16b. The solid-liquid separator 16 is arranged obliquely relative to the extension direction of the recovery pipe 12, and the first end 16a is closer to the box cover 114 relative to the second end 16b. Figure 9 shown.

[0131] In the above manner, when the dirt storage assembly 10 is in a flat position, the solid-liquid separator 16 extends in a direction away from the box cover 114 and away from the surface to be cleaned 20. When the user pulls back the cleaning device 30, that is, the dirt storage assembly 10 is in a flat position and moves along the box body 113 toward the box cover 114, at least a portion of the liquid in the solid dirt storage chamber 1111 will flow along the solid-liquid separator 16 in a direction away from the box cover 114 and away from the surface to be cleaned 20 due to inertia. This can buffer the surge and extend the flow path of the surge, further weakening the surge and reducing the risk of liquid backflowing into the air intake 112. If the solid-liquid separator 16 is perpendicular to the surface to be cleaned 20 when the dirt storage assembly 10 is in a flat position, and the user pulls back the cleaning device 30, the liquid in the solid dirt storage chamber 1111 will directly impact the solid-liquid separator 16. Under the reaction force of the solid-liquid separator 16, the liquid will flow back, thereby increasing the surge and undoubtedly increasing the risk of liquid backflowing into the air intake 112.

[0132] Furthermore, at least the area near the second end 16b of the solid-liquid separator 16 is provided with separation holes, that is, the second separation portion 16d is provided with a second separation hole 168. In this way, when the user pulls back the cleaning device 30, at least part of the liquid in the solid dirt storage chamber 1111 flows along the solid-liquid separator 16 under the action of inertia in the direction away from the box cover 114 and away from the surface to be cleaned 20. When the liquid flows to the area near the second end 16b of the solid-liquid separator 16, the liquid can flow into the liquid dirt storage chamber 1112, that is, when the liquid flows to the area near the second end 16b of the solid-liquid separator 16, it flows from the second separation hole 168 of the second separation portion 16d into the liquid dirt storage chamber 1112, thereby realizing the recovery of liquid dirt while reducing the amount of liquid in the solid dirt storage chamber 1111, and also reducing the risk of liquid backflowing into the air intake 112.

[0133] The first separation portion 16c of the solid-liquid separator 16 is provided with a first separation hole 161, and the second separation portion 16d is provided with a second separation hole 168. The first separation hole 161 and the second separation hole 168 not only serve to separate solid dirt and liquid dirt, but also serve to weaken surges. When the user pulls back the cleaning device 30, the liquid in the solid dirt storage chamber 1111 moves to the solid-liquid separator 16, and part of the liquid flows along the solid-liquid separator 16 in a direction away from the box cover 114 and away from the surface to be cleaned 20, and part of the liquid directly enters the liquid dirt storage chamber 1112 through the first separation hole 161, thereby recovering the liquid dirt and weakening the surge. The above two forms cooperate with each other to greatly weaken the surge and reduce the risk of liquid backflowing into the air intake 112.

[0134] Further, if Figure 7As shown, the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is θ1, which satisfies: 40°≤θ1≤60°. This embodiment can ensure that the solid-liquid separator 16 can achieve the function of weakening surges by reasonably setting the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12, and can also prevent the size of the solid-liquid separator 16 from exceeding the limit. If the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is too small, the solid-liquid separator 16 cannot significantly weaken the surge; if the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is too large, there is a hidden danger that the length of the solid-liquid separator 16 is too long, which will affect the arrangement of other components in the sewage storage chamber 111. Alternatively, θ1 may be any value of 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, or 60°.

[0135] Please also refer to Figures 16 to 18 , Figure 16 yes Figure 10 The rear view of the box cover and the separation structure is shown. Figure 17 yes Figure 16 The schematic diagram of the structure of the box cover and the separation structure F area is shown. Figure 18 yes Figure 16 Schematic diagram of the cross-sectional structure of the box cover and the separation structure in the GG direction.

[0136] In one embodiment, the separation structure 10a includes a one-way plate 15. The one-way plate 15 is rotatably disposed on the solid-liquid separator 16 to close or open the separation hole. The one-way plate 15 is rotatably connected to the solid-liquid separator 16 via a rotating shaft 151. Specifically, the one-way plate 15 is rotatably connected to the first separation portion 16c to close or open the first separation hole 161. Of course, in other embodiments of the present application, the solid-liquid separator 16 may not be provided with the second separation portion 16d. The embodiments of the present application are described by taking the one-way plate 15 configured to close or open the first separation hole 161 as an example, which is only for the purpose of discussion and does not constitute a limitation.

[0137] The one-way plate 15 is rotatably mounted on the side of the solid-liquid separator 16 away from the cover 114, that is, the one-way plate 15 is rotatably connected to the side of the solid-liquid separator 16 facing the liquid waste storage chamber 1112. When the waste storage assembly 10 is in an upright position, the cover 114 and the housing 113 are arranged one above the other, and the rotation axis 151 of the one-way plate 15 is located below the first separation hole 161. The one-way plate 15 rotates under the action of gravity to open the first separation hole 161. When the waste storage assembly 10 is in a flat position, the housing 113 and the cover 114 are arranged horizontally adjacent to each other, and the rotation axis 151 of the one-way plate 15 is located above the first separation hole 161. Under the hydraulic pressure of the liquid in the liquid waste storage chamber 1112, the one-way plate 15 has a tendency to close the first separation hole 161, while under the hydraulic pressure of the liquid in the solid waste storage chamber 1111, the one-way plate 15 has a tendency to open the first separation hole 161.

[0138] The one-way plate 15 is rotatably connected to the side of the solid-liquid separator 16 facing the liquid dirt storage chamber; the dirt storage chamber 111 of the dirt storage assembly 10 is provided with a first preset liquid storage volume, a second preset liquid storage volume, and a third preset liquid storage volume; the first preset liquid storage volume, the second preset liquid storage volume, and the third preset liquid storage volume decrease in sequence, and the first preset liquid storage volume is the safe liquid storage limit of the dirt storage chamber 111;

[0139] When the liquid storage volume of the dirt storage chamber 111 is greater than the second preset liquid storage volume and less than the first preset liquid storage volume, and the dirt storage assembly 10 is in a flat state, the one-way plate 15 closes the first separation hole 161 under the hydraulic pressure of the liquid in the liquid dirt storage chamber;

[0140] When the liquid storage volume of the dirt storage chamber 111 is greater than the third preset liquid storage volume and less than the second preset liquid storage volume, and the dirt storage assembly 10 is in a flat state and moves along the box body 113 toward the box cover 114, the one-way plate 15 closes the first separation hole 161 under the hydraulic pressure of the liquid in the liquid dirt storage chamber;

[0141] When the liquid storage volume of the dirt storage chamber 111 is greater than the third preset liquid storage volume and less than the second preset liquid storage volume, and the dirt storage assembly 10 is in a flat state and moves along the box cover 114 toward the box body 113, the one-way plate 15 opens the first separation hole 161 under the hydraulic pressure of the liquid in the solid dirt storage chamber;

[0142] When the liquid storage volume of the dirt storage chamber 111 is less than the third preset liquid storage volume, the dirt storage assembly 10 is in a flat position, and moves along the box body 113 toward the box cover 114, the one-way plate 15 rotates under the inertia of the liquid in the solid dirt storage chamber to open the first separation hole 161;

[0143] When the liquid storage volume of the dirt storage chamber 111 is less than the third preset liquid storage volume, the dirt storage assembly 10 is in a lying state, and moves along the box cover 114 toward the box body 113, the one-way plate 15 rotates under the impact of the inertia of the liquid in the liquid dirt storage chamber to close the first separation hole 161.

[0144] Specifically, if Figure 13 As shown, when the liquid storage volume of the dirt storage chamber 111 is less than the third preset liquid storage volume, for example, the third preset liquid storage volume is set to 20 ml, when the dirt storage assembly 10 is in a flat state, when the dirt storage assembly 10 retreats, that is, the dirt storage assembly 10 moves along the box body 113 toward the box cover 114, the one-way plate 15 rotates in a direction away from the solid-liquid separator 16 under the impact of the inertia of the liquid in the solid dirt storage chamber 1111, so as to open the first separation hole 161; Figure 14 As shown, when the sewage storage assembly 10 moves forward, that is, moves along the tank cover 114 toward the tank body 113, the one-way plate 15 rotates toward the solid-liquid separator 16 under the inertial impact of the liquid in the liquid sewage storage chamber 1112, thereby closing the first separation hole 161. When the sewage storage assembly 10 is in a flat position and stops moving, the one-way plate 15 rotates under the hydraulic pressure of the liquid in the liquid sewage storage chamber 1112, thereby closing the first separation hole 161.

[0145] Since when the liquid storage volume of the sewage storage chamber 111 is small, that is, the liquid storage volume of the sewage storage chamber 111 is less than the third preset liquid storage volume, the risk of liquid backflowing into the air intake 112 is low, the embodiment of the present application mainly discusses the situation where the liquid storage volume of the sewage storage chamber 111 is greater than the second preset liquid storage volume and less than the first preset liquid storage volume, as follows.

[0146] When the user needs to use the cleaning device 30 to clean low areas such as under a bed, under a sofa, under a table or chair, the dirt storage assembly 10 is in a lying state. When the user pushes the cleaning device 30 forward, the dirt storage assembly 10 moves forward, and the liquid in the solid dirt storage chamber 1111 passes through the first separation hole 161 and acts on the one-way plate 15, so that the one-way plate 15 rotates in the direction away from the solid-liquid separator 16 under the impact of the liquid in the solid dirt storage chamber 1111 to open the first separation hole 161, and the liquid enters the liquid dirt storage chamber 1112 through the first separation hole 161, thereby realizing the recovery of liquid dirt and weakening the surge to a certain extent through the first separation hole 161; when the user pulls the cleaning device 30 backward, the dirt storage assembly 10 retreats, and the liquid in the liquid dirt storage chamber 1112 acts on the one-way plate 15, so that the one-way plate 15 rotates toward the solid-liquid separator 16 under the impact of the liquid in the liquid dirt storage chamber 1112 to close the first separation hole 161, and prevent the liquid in the liquid dirt storage chamber 1112 from flowing back to the solid dirt storage chamber 1111.

[0147] Further, please also refer to Figure 7 When the sewage storage assembly 10 is in an upright or tilted position, the one-way plate 15 rotates under its own weight to open the first separation hole 161. When the sewage storage assembly 10 is in an upright or tilted position, the one-way plate 15 maintains the first separation hole 161 open under its own weight. The one-way plate 15 is not connected to the solid-liquid separator 16 via a spring, torsion spring, or other means. As a result, when the sewage storage assembly 10 is in a flat position, as the sewage storage assembly 10 moves forward, the liquid in the solid waste storage chamber 1111 more easily drives the one-way plate 15 to rotate away from the solid-liquid separator 16, thereby opening the first separation hole 161 and effectively ensuring the surge reduction function. When the sewage storage assembly 10 moves backward, the liquid in the liquid waste storage chamber 1112 also more easily drives the one-way plate 15 toward the solid-liquid separator 16, thereby closing the first separation hole 161 and effectively preventing the liquid in the liquid waste storage chamber 1112 from flowing back into the solid waste storage chamber 1111. Moreover, when the dirt storage assembly 10 is in an upright state or an inclined use state, the one-way plate 15 keeps the first separation hole 161 open, and the dirt enters the solid dirt storage chamber 1111 under the action of its own gravity, and the liquid dirt enters the liquid dirt storage chamber 1112 under the separation of the solid-liquid separator 16.

[0148] Further, if Figure 7 As shown, the maximum angle between the one-way plate 15 and the solid-liquid separator 16 is θ2, which satisfies the following: 40°≤θ2≤60°. The maximum angle between the one-way plate 15 and the solid-liquid separator 16 is the maximum rotation angle of the one-way plate 15. This embodiment reasonably sets the maximum rotation angle of the one-way plate 15. On the one hand, it ensures that the one-way plate 15 opens the first separation hole 161, so that the liquid in the solid dirt storage chamber 1111 is recovered to the liquid dirt storage chamber 1112 through the first separation hole 161, thereby recovering the liquid dirt and reducing surges. On the other hand, the maximum rotation angle of the one-way plate 15 is not too large, which can ensure that the liquid in the liquid dirt storage chamber 1112 stably drives the one-way plate 15 to rotate toward the solid-liquid separator 16 to close the first separation hole 161 when the dirt storage assembly 10 moves forward, ensuring that the function of the one-way plate 15 is stable and reliable.

[0149] In one embodiment, if Figure 17 As shown, the solid-liquid separator 16 is provided with a connecting portion 164 and a limiting portion 165. The one-way plate 15 is rotatably connected to the connecting portion 164, and the limiting portion 165 is used to abut the one-way plate 15 during the process of the one-way plate 15 rotating away from the solid-liquid separator 16, thereby limiting the one-way plate 15 from further rotation.

[0150] For example, the connection portion 164 defines a connection hole 1641, into which the rotational axis 151 of the one-way plate 15 is rotatably embedded, allowing the one-way plate 15 to rotate relative to the solid-liquid separator 16. The one-way plate 15 is provided with a connection portion 164 and a stop portion 165 on either side. A rotational axis 151 is provided on either side of the one-way plate 15, each rotational axis 151 being embedded in a connection hole 1641 of the connection portion 164 on the same side.

[0151] In one embodiment, the solid-liquid separator 16 includes a main body 166 and a protrusion 167. The protrusion 167 is provided to protrude relative to the main body 166 toward the box cover 114. Specifically, the main body 166 has a first surface 1661 facing away from the air inlet 112. The protrusion 167 is connected to the main body 166 and has a second surface 1671 facing away from the air inlet 112. The second surface 1671 is closer to the air inlet 112 than the first surface 1661. Figure 18 The main body portion 166 and the protruding portion 167 are both provided with a first separation hole 161 .

[0152] The one-way plate 15 is positioned opposite the protrusion 167. When the one-way plate 15 closes the first separation hole 161, the second surface 1671 of the protrusion 167 is spaced apart from the one-way plate 15, reducing the risk of dirt being trapped between the one-way plate 15 and the solid-liquid separator 16. This prevents dirt from being trapped between the one-way plate 15 and the solid-liquid separator 16, preventing the one-way plate 15 from completely closing the first separation hole 161. This reduces the risk of liquid in the liquid dirt storage chamber 1112 flowing back into the solid dirt storage chamber 1111, thereby reducing the risk of liquid in the solid dirt storage chamber 1111 and thus backflowing into the air intake 112.

[0153] In one embodiment, the separation structure 10a includes a liquid-permeable member 162. The liquid-permeable member 162 is disposed between the partition member 13 and the solid-liquid separation member 16. When the dirt storage assembly 10 is in a flat position, the liquid-permeable member 162 is located on the side of the solid dirt storage chamber 1111 close to the surface to be cleaned 20. The liquid-permeable member 162 is provided with a liquid-permeable hole 163. When the user needs to clean the dirt storage assembly 10, the user lifts the box cover 114, and the separation structure 10a is separated from the box body 113 together with the box cover 114. The liquid in the solid dirt storage chamber 1111 can flow back into the box body 113 through the liquid-permeable hole 163 on the liquid-permeable member 162, thereby reducing the liquid residue in the solid dirt storage chamber 1111 and facilitating the user's cleaning of the dirt storage assembly 10.

[0154] Furthermore, the number of liquid permeable holes 163 can be multiple. The multiple liquid permeable holes 163 are spaced apart along the extension direction of the air inlet 112, that is, the multiple liquid permeable holes 163 are spaced apart along the third direction Y. The liquid permeable holes 163 extend in a direction close to the box cover 114, so that the liquid permeable holes 163 are elongated.

[0155] In one embodiment, the cross-sectional area of the housing 113 near the lid 114 is greater than the cross-sectional area of the housing 113 away from the lid 114. When the lid 114 is separated from the housing 113, a gap is formed between the first sealing member 191 and the inner wall of the housing 113. When the user needs to clean the dirt storage assembly 10, the user lifts the lid 114 to separate the lid 114 from the housing 113, forming a gap between the first sealing member 191 and the inner wall of the housing 113. The liquid in the solid dirt storage chamber 1111 flows back into the housing 113 through the liquid-permeable hole 163 on the liquid-permeable member 162 and the gap between the first sealing member 191 and the inner wall of the housing 113, thereby reducing the residual liquid in the solid dirt storage chamber 1111 and facilitating the user's cleaning of the dirt storage assembly 10.

[0156] In one embodiment, the air inlet 112 is provided on the box cover 114, and the cross-sectional area of the box body 113 near the box cover 114 is larger than the cross-sectional area of the box body 113 away from the box cover 114. Furthermore, the box body 113 may be gradually enlarged toward the box cover 114. In this way, by providing a larger cross-sectional area of the box body 113 near the box cover 114, this embodiment can reduce the airflow velocity of the box body 113 near the box cover 114, that is, reduce the airflow velocity at the air inlet 112, thereby reducing the risk of dirt backflowing into the air inlet 112.

[0157] Please also refer to Figures 19 to 22 , Figure 19 This is a structural diagram of another embodiment of the box cover and separation structure of the present application. Figure 20 This is a structural diagram of an embodiment of the mounting bracket of the present application. Figure 21 yes Figure 19 The schematic diagram of the structure of the box cover and the separation structure from another perspective is shown. Figure 22 yes Figure 21 The side view of the box cover and the separation structure is shown.

[0158] In one embodiment, the separation structure 10a includes a mounting frame 17. The mounting frame 17 is disposed in the dirt storage chamber 111, and the mounting frame 17 is connected to the box cover 114. The mounting frame 17 has a mounting cavity 171, and the mounting frame 17 is provided with a detection hole 172 connecting the dirt storage chamber 111 and the mounting cavity 171. The separation structure 10a includes a liquid level detection element 18, and the liquid level detection element 18 is disposed in the mounting cavity 171. When the dirt storage assembly 10 is in an upright state, the liquid level detection element 18 is located below the box cover 114; when the dirt storage assembly 10 is in a flat state, the liquid level detection element 18 and the box cover 114 are arranged along the surface to be cleaned 20, that is, the arrangement direction of the liquid level detection element 18 and the box cover 114 is parallel to the surface to be cleaned 20.

[0159] In the above manner, the liquid level detection element 18 is used to detect the liquid level in the dirt storage chamber 111. When the liquid level in the dirt storage chamber 111 reaches a set level, it is considered that the liquid storage volume in the dirt storage chamber 111 has reached the maximum value, and the user needs to be notified to clean the dirt storage chamber 111 in a timely manner so that the dirt storage assembly 10 can be used again for cleaning. In this embodiment, a mounting bracket 17 is provided, and the liquid level detection element 18 is disposed in the mounting cavity 171 of the mounting bracket 17. When the liquid level in the dirt storage chamber 111 reaches the set level, the liquid in the dirt storage chamber 111 enters the mounting cavity 171 through the detection hole 172 on the mounting bracket 17 and then contacts the liquid level detection element 18. In this way, the liquid level detection element 18 is wrapped by the mounting frame 17, which can reduce the risk of the liquid in the sewage storage chamber 111 accidentally triggering the liquid level detection element 18 due to shaking when the liquid level in the sewage storage chamber 111 does not reach the set liquid level, thereby improving the monitoring accuracy of the liquid level in the sewage storage chamber 111; and, the liquid in the sewage storage chamber 111 slowly enters the mounting chamber 171 through the detection hole 172, which can further reduce the risk of the liquid in the sewage storage chamber 111 accidentally triggering the liquid level detection element 18, thereby improving the monitoring accuracy of the liquid level in the sewage storage chamber 111; in this embodiment, the monitoring accuracy of the liquid level in the sewage storage chamber 111 is guaranteed, which can greatly reduce the risk of the liquid level in the sewage storage chamber 111 being too high, and avoid as much as possible the increased risk of dirt flowing back into the air intake 112 due to excessive liquid in the sewage storage chamber 111.

[0160] In particular, when the user needs to use the cleaning device 30 to clean low areas such as under the bed, under the sofa, under the table and chairs, the dirt storage assembly 10 is in a flat state. The user pushes the cleaning device 30 forward and pulls the cleaning device 30 backward, and the liquid in the dirt storage chamber 111 surges back and forth to form a surge. When the sewage tank of a traditional floor scrubber is in a flat state, the surge formed in the sewage tank can easily flow back into the vacuum motor from the air intake 112. In view of this, the present embodiment provides a mounting bracket 17 and arranges the liquid level detection element 18 in the mounting cavity 171 of the mounting bracket 17. The liquid level detection element 18 is wrapped by the mounting bracket 17, which can reduce the risk of the liquid in the dirt storage chamber 111 mistakenly triggering the liquid level detection element 18 due to shaking when the liquid level in the dirt storage chamber 111 does not reach the set liquid level, thereby improving the monitoring accuracy of the liquid level in the dirt storage chamber 111. It is precisely because the monitoring accuracy of the liquid level in the sewage storage chamber 111 is guaranteed in this embodiment that the risk of the liquid level in the sewage storage chamber 111 being too high can be greatly reduced, and the risk of dirt flowing back into the air intake 112 due to excessive liquid in the sewage storage chamber 111 can be avoided as much as possible.

[0161] When the sewage tank of a traditional floor scrubber is in a flat position, in order to prevent sewage from flowing back into the air intake 112, it is usually necessary to reduce the suction force of the vacuum motor, which will inevitably lead to a decrease in the efficiency of dirt recovery, causing the cleaning effect of the traditional floor scrubber to be greatly reduced. In this embodiment, since the monitoring accuracy of the liquid level in the dirt storage chamber 111 is guaranteed, it can promptly and accurately feedback the situation where the liquid level in the dirt storage chamber 111 is too high. Therefore, when the dirt storage component 10 is in a flat position, this embodiment can control the vacuum motor to output a larger suction force to ensure the dirt recovery efficiency. This embodiment may not even need to reduce the suction force of the vacuum motor, and when the liquid level in the dirt storage chamber 111 is too high, it will promptly prompt the user to clean it, greatly reducing the risk of dirt flowing back into the air intake 112. It can be seen that the dirt storage component 10 of this embodiment still has good dirt recovery efficiency in the flat position to ensure the cleaning effect of the cleaning device 30, while also reducing the risk of damage to the vacuum motor.

[0162] It should be noted that the flow area of the detection hole 172 is S2 mm 2 , satisfying: 10 ≤ S2 ≤ 20. By properly setting the flow area of detection hole 172, this embodiment can reasonably control the rate at which liquid in the dirt storage chamber 111 enters the mounting chamber 171. This reduces the risk of liquid in the dirt storage chamber 111 falsely triggering the liquid level detection element 18, thereby improving the monitoring accuracy of the liquid level in the dirt storage chamber 111, and ensures that the liquid level detection element 18 promptly reports that the liquid storage volume in the dirt storage chamber 111 has reached its maximum value. Optionally, S2 can be any value among 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

[0163] In one embodiment, the detection hole 172 is a strip-shaped hole with a length of 5 to 10 mm and a width of 2 to 5 mm. The width / length ratio is preferably 4. In this way, the rate at which the liquid enters the installation cavity 171 can be slowed down without affecting its flow area, thereby further reducing the risk of false detection by the liquid level detection element 18. The narrow and long design of the detection hole 172 can also prevent larger solid dirt (such as melon seed shells, orange seeds, etc.) from entering the installation cavity 171 through the detection hole 172, causing false alarms, blockages, difficulty in cleaning, and other problems.

[0164] In one embodiment, the main unit 31 of the cleaning device 30 may include a control module and a voice prompt module. The liquid level detection element 18 of the dirt storage assembly 10 and the voice prompt module are both electrically connected to the control module. The liquid level detection element 18 is configured to output an alarm signal to the control module upon contact with liquid. The control module, triggered by the alarm signal, controls the voice prompt module to issue an alarm, prompting the user to promptly clean the dirt storage chamber 111 so that the dirt storage assembly 10 can be reused for cleaning operations.

[0165] In one embodiment, the mounting cavity 171 includes a first mounting cavity 171a and a second mounting cavity 171b spaced apart from each other. The liquid level detecting element 18 includes a first liquid level detecting element 18a and a second liquid level detecting element 18b spaced apart from each other. The first liquid level detecting element 18a is located within the first mounting cavity 171a, and the second liquid level detecting element 18b is located within the second mounting cavity 171b. The mounting frame 17 is provided with different detection holes 172 corresponding to the first and second mounting cavities 171a, 171b, respectively. Liquid in the dirt storage chamber 111 enters the first and second mounting cavities 171a, 171b through the corresponding detection holes 172. When the first and second liquid level detecting elements 18a, 18b simultaneously contact liquid, the detection circuit between the first and second liquid level detecting elements 18a, 18b is connected, indicating that the liquid level in the dirt storage chamber 111 has reached a set level and the liquid storage capacity in the dirt storage chamber 111 has reached its maximum value.

[0166] Specifically, when the dirt storage assembly 10 is in an upright position, the first and second liquid level detection elements 18a, 18b are at the same distance from the bottom of the housing 113; when the dirt storage assembly 10 is in a flat position, the first and second liquid level detection elements 18a, 18b are at the same distance from the surface to be cleaned 20. In other words, the heights of the first and second liquid level detection elements 18a, 18b represent the amount of liquid stored in the dirt storage assembly 10 in both the upright and flat positions. In this embodiment, the heights of the first and second liquid level detection elements 18a, 18b are consistent, which facilitates the first and second liquid level detection elements 18a, 18b to accurately report when the liquid level in the dirt storage chamber 111 has reached the set level, thereby improving the accuracy of monitoring the liquid level in the dirt storage chamber 111 and significantly reducing the risk of excessively high liquid levels in the dirt storage chamber 111. This minimizes the risk of backflow of dirt into the air intake 112 due to excessive liquid in the dirt storage chamber 111.

[0167] If the heights of the first liquid level detection element 18a and the second liquid level detection element 18b are inconsistent, regardless of whether the dirt storage assembly 10 is in an upright state or a lying state, the detection circuit between the first liquid level detection element 18a and the second liquid level detection element 18b will be triggered to be connected only when the higher liquid level detection element 18 contacts the liquid. At this time, the liquid level in the dirt storage chamber 111 is already too high, resulting in no feedback on the situation where the liquid level in the dirt storage chamber 111 reaches the set liquid level, and greatly increasing the risk of dirt backflowing into the air intake 112.

[0168] The relative directions of the first installation cavity 171a and the second installation cavity 171b, as well as the relative directions of the first liquid level detection element 18a and the second liquid level detection element 18b, are both perpendicular to the extension direction of the recovery pipe 12. Furthermore, when the dirt storage assembly 10 is in a flat position, the relative directions of the first installation cavity 171a and the second installation cavity 171b, as well as the relative directions of the first liquid level detection element 18a and the second liquid level detection element 18b, are also parallel to the surface to be cleaned 20.

[0169] It should be noted that the structure of the mounting frame 17 corresponding to the first liquid level detection element 18a, including the first mounting cavity 171a, is similar to the structure of the mounting frame 17 corresponding to the second liquid level detection element 18b, including the second mounting cavity 171b. This embodiment of the present application uses the structure of the mounting frame 17 corresponding to the first liquid level detection element 18a as an example for illustration only, and is not intended to be limiting. Of course, in other embodiments of the present application, only one set of liquid level detection elements 18 may be provided. When the liquid level detection element 18 contacts liquid, the two detection electrodes of the liquid level detection element 18 are electrically conductive to provide feedback on the current liquid level in the sewage storage chamber 111. The operating principles of the liquid level detection element 18 and its detection electrodes are within the scope of understanding of those skilled in the art and will not be elaborated upon here.

[0170] In one embodiment, the end of the mounting frame 17 away from the air inlet 112 has a first opening 173. The solid-liquid separator 16 is disposed to close the first opening 173.

[0171] Through the above-described method, the solid-liquid separator 16 of this embodiment is docked with the mounting bracket 17, so that the solid-liquid separator 16 covers the first opening 173 to close the first opening 173. The mounting bracket 17 and the solid-liquid separator 16 cooperate to enclose the mounting cavity 171, which helps simplify the structure of the mounting bracket 17. The solid-liquid separator 16 and the mounting bracket 17 cooperate to separate the liquid level detection element 18 from the liquid in the dirt storage chamber 111. The liquid in the dirt storage chamber 111 slowly enters the mounting cavity 171 through the detection hole 172, reducing the risk of the liquid in the dirt storage chamber 111 falsely triggering the liquid level detection element 18 and improving the monitoring accuracy of the liquid level in the dirt storage chamber 111.

[0172] Specifically, the mounting bracket 17 includes a first mounting portion 1751, a second mounting portion 1752, a third mounting portion 1753, and a fourth mounting portion 1754. The first mounting portion 1751 is disposed opposite the first opening 173. The second mounting portion 1752 is connected to one side of the first mounting portion 1751. The third mounting portion 1753 is connected to the other side of the first mounting portion 1751. When the dirt storage assembly 10 is in a flat position, the second mounting portion 1752 is closer to the surface to be cleaned 20 relative to the third mounting portion 1753. The fourth mounting portion 1754 is connected to the side of the first mounting portion 1751, the second mounting portion 1752, and the third mounting portion 1753 that is away from the inner wall of the housing 113. The first mounting portion 1751 , the second mounting portion 1752 , the third mounting portion 1753 and the fourth mounting portion 1754 cooperate to enclose the mounting cavity 171 , and the second mounting portion 1752 , the third mounting portion 1753 and the fourth mounting portion 1754 also cooperate to enclose the first opening 173 .

[0173] In one embodiment, the mounting bracket 17 has a second opening 174 on a side adjacent to the inner wall of the housing 113. The inner wall of the housing 113 encloses the second opening 174. Specifically, the first mounting portion 1751, the second mounting portion 1752, and the third mounting portion 1753 cooperate to define the second opening 174. The second opening 174 is located on the side of the first mounting portion 1751, the second mounting portion 1752, and the third mounting portion 1753 that is distal from the fourth mounting portion 1754. Thus, in this embodiment, the inner wall of the housing 113 and the mounting bracket 17 are docked, allowing the inner wall of the housing 113 to cover the second opening 174, thereby enclosing the second opening 174. The inner wall of the housing 113 and the mounting bracket 17 cooperate to define the mounting cavity 171, thereby simplifying the structure of the mounting bracket 17. The inner wall of the box body 113 cooperates with the mounting frame 17 to separate the liquid level detection element 18 from the liquid in the dirt storage chamber 111. The liquid in the dirt storage chamber 111 slowly enters the mounting chamber 171 through the detection hole 172, reducing the risk of the liquid in the dirt storage chamber 111 mistakenly triggering the liquid level detection element 18 and improving the monitoring accuracy of the liquid level in the dirt storage chamber 111.

[0174] In one embodiment, the sewage storage assembly 10 includes a first seal 191, which is disposed on the periphery of the solid-liquid separator 16 and seals the solid-liquid separator 16 against the inner wall of the sewage storage tank 11. The sewage storage assembly 10 also includes a second seal 192, which is disposed on the mounting bracket 17 and seals the mounting bracket 17 against the inner wall of the sewage storage tank 11. Specifically, the mounting bracket 17 and the solid-liquid separator 16 are docked together, creating a relative seal between them. The first seal 191 also seals the first opening 173 circumferentially. The second seal 192 is disposed around the periphery of the second opening 174, and the first and second seals 191 and 192 cooperate to seal the second opening 174 circumferentially. This minimizes the risk of liquid in the sewage storage chamber 111 entering the mounting chamber 171 from locations other than the detection hole 172, further improving the accuracy of liquid level monitoring in the sewage storage chamber 111.

[0175] Of course, in other embodiments of the present application, the mounting frame 17 can form a fully enclosed structure, that is, the mounting cavity 171 is enclosed only by the mounting frame 17. Specifically, the mounting frame 17 further includes a sixth mounting portion and a seventh mounting portion. The sixth mounting portion is connected to the side of the second mounting portion 1752 and the third mounting portion 1753 away from the first mounting portion 1751, and the seventh mounting portion is connected to the side of the second mounting portion 1752 and the third mounting portion 1753 away from the fourth mounting portion 1754. The first mounting portion 1751, the second mounting portion 1752, the third mounting portion 1753, the fourth mounting portion 1754, the sixth mounting portion, and the seventh mounting portion cooperate to enclose the mounting cavity 171. The mounting cavity 171 is enclosed by the mounting frame 17, which can reduce the coordination design between the mounting frame 17 and other components and can simplify the structural design of the mounting frame 17 to a certain extent.

[0176] In one embodiment, the mounting bracket 17 further includes a fifth mounting portion 1755, and the first mounting portion 1751 is connected to the box cover 114 through the fifth mounting portion 1755. Furthermore, the fifth mounting portion 1755 extends toward the box cover 114, and the interior of the fifth mounting portion 1755 has a mounting channel 176 extending toward the box cover 114, and the mounting channel 176 is connected to the mounting cavity 171. The liquid level detection element 18 is arranged in the mounting channel 176, and the detection head 181 of the liquid level detection element 18 is located in the mounting cavity 171. In this embodiment, the detection head 181 of the liquid level detection element 18 is used to detect the liquid level of the liquid in the dirt storage cavity 111. The detection head 181 of the liquid level detection element 18 is arranged in the mounting cavity 171 of the mounting bracket 17. When the liquid level in the dirt storage chamber 111 reaches the set level, the liquid in the dirt storage chamber 111 enters the mounting chamber 171 through the detection hole 172 on the mounting bracket 17 and then contacts the detection head 181 of the liquid level detection element 18. Thus, the detection head 181 of the liquid level detection element 18 is enclosed by the mounting bracket 17. This reduces the risk of the detection head 181 of the liquid level detection element 18 being falsely triggered by sloshing of the liquid in the dirt storage chamber 111 when the liquid level in the dirt storage chamber 111 has not reached the set level, thereby improving the accuracy of monitoring the liquid level in the dirt storage chamber 111.

[0177] In one embodiment, the sewage storage assembly 10 includes a third seal 193. This seal 193 is located on the side of the fifth mounting portion 1755 of the mounting bracket 17 that faces the inner sidewall of the housing 113. The third seal 193 extends toward the housing cover 114. This seal 193 forms a seal between the mounting bracket 17 and the housing 113. When the sewage storage assembly 10 is in a flat position, the third seal 193 prevents liquid at the bottom of the sewage storage assembly 10 from flowing through the gap between the mounting bracket 17 and the housing 113 toward the air intake 112, further reducing the risk of backflow of dirt into the air intake 112.

[0178] In the example described above where the mounting cavity 171 includes a first mounting cavity 171a and a second mounting cavity 171b, fifth mounting portions 1755 are provided on both sides of the mounting frame 17. A third sealing member 193 is provided on the side of each fifth mounting portion 1755 facing the inner sidewall of the housing 113. The third sealing members 193 form a seal between the mounting frame 17 and the housing 113. The third sealing members 193 are used to prevent liquid at the bottom of the sewage storage assembly 10 from flowing through the gap between the mounting frame 17 and the housing 113 toward the air intake 112 when the sewage storage assembly 10 is in a flat position, thereby further reducing the risk of backflow of dirt into the air intake 112.

[0179] In one embodiment, the dirt storage assembly 10 further includes a fourth seal 194. This seal 194 surrounds the outer periphery of the chamber lid 114, creating a seal between the chamber lid 114 and the chamber body 113. This seal 194 maintains a negative pressure environment within the dirt storage chamber 111, thereby ensuring efficient dirt recovery. The third seal 193 extends to the second seal 192 and the fourth seal 194 at both ends, forming a complete seal.

[0180] It should be noted that the first sealing member 191 , the second sealing member 192 , the third sealing member 193 , the fourth sealing member 194 and the fifth sealing member 195 may be a sealing soft adhesive structure such as silicone or rubber, which is not limited here.

[0181] In one embodiment, the dirt storage assembly 10 is in a flat position, and the opening of the detection hole 172 faces the surface to be cleaned 20. During the cleaning process of the cleaning device 30, the dirt storage assembly 10 is in a flat position and collects dirt from the surface to be cleaned 20. The liquid level in the dirt storage chamber 111 gradually rises until the liquid in the dirt storage chamber 111 enters the installation chamber 171 through the detection hole 172, triggering the liquid level detection element 18, thereby prompting the user to clean the dirt storage chamber 111 in a timely manner. In this embodiment, the opening of the detection hole 172 is arranged to face the surface to be cleaned 20 when the dirt storage component 10 is in a lying state. When the liquid in the dirt storage chamber 111 seeps into the installation chamber 171, it is conducive to making the liquid level of the liquid in the installation chamber 171 consistent with the liquid level of the liquid in the dirt storage chamber 111, that is, the liquid level of the liquid in the installation chamber 171 accurately reflects the liquid level of the liquid in the dirt storage chamber 111, further improving the monitoring accuracy of the liquid level in the dirt storage chamber 111. In this way, not only can the user be prompted to clean the dirt storage chamber 111 in time, but also the risk of the liquid level in the dirt storage chamber 111 being too high can be greatly reduced, and the risk of dirt flowing back into the air intake 112 due to excessive liquid in the dirt storage chamber 111 can be avoided as much as possible.

[0182] If the opening of the detection hole 172 faces away from the surface to be cleaned 20 when the dirt storage assembly 10 is in a flat position, this means that the height of the liquid level detection element 18 must be lower than the height of the detection hole 172. In other words, the liquid level in the dirt storage chamber 111 must exceed the height of the liquid level detection element 18 and the detection hole 172 before the liquid in the dirt storage chamber 111 can enter the installation chamber 171 through the detection hole 172 and trigger the liquid level detection element 18. In other words, if the opening of the detection hole 172 faces away from the surface to be cleaned 20 when the dirt storage assembly 10 is in a flat position, the liquid stored in the dirt storage chamber 111 is already excessive when the liquid level detection element 18 is triggered, resulting in the liquid level detection element 18 being unable to promptly report the excessively high liquid level in the dirt storage chamber 111. The excess liquid in the dirt storage chamber 111 also increases the risk of dirt flowing back into the air intake 112.

[0183] Specifically, based on the example of the mounting bracket 17 described above, the detection hole 172 of this embodiment can be provided in the second mounting portion 1752. When the dirt storage assembly 10 is in a flat position, the detection hole 172 is located in the portion of the mounting bracket 17 close to the surface to be cleaned 20 (i.e., the second mounting portion 1752), and the opening of the detection hole 172 faces the inner side wall of the housing 113 and the surface to be cleaned 20. When the dirt storage assembly 10 is in a lying state and recovers dirt on the surface to be cleaned 20, the liquid level in the dirt storage chamber 111 gradually rises until the liquid in the dirt storage chamber 111 enters the installation chamber 171 through the detection hole 172 and triggers the liquid level detection element 18. At this time, the liquid level in the installation chamber 171 is consistent with the liquid level in the dirt storage chamber 111, that is, the liquid level in the installation chamber 171 accurately reflects the liquid level in the dirt storage chamber 111, thereby improving the monitoring accuracy of the liquid level in the dirt storage chamber 111. This not only prompts the user to clean the dirt storage chamber 111 in time, but also greatly reduces the risk of the liquid level in the dirt storage chamber 111 being too high, and avoids as much as possible the increased risk of dirt flowing back into the air intake 112 due to excessive liquid in the dirt storage chamber 111.

[0184] Of course, in other embodiments of the present application, the opening of the detection hole 172 can also be directed toward the box cover 114, etc., that is, the detection hole 172 is opened in the first mounting portion 1751 of the mounting frame 17; or the detection hole 172 can also be opened in the fourth mounting portion 1754 of the mounting frame 17, etc.; or, for the example in which the mounting frame 17 also includes a sixth mounting portion and a seventh mounting portion, the detection hole 172 can also be opened in the sixth mounting portion and / or the seventh mounting portion, which is not limited here.

[0185] In one embodiment, when the sewage storage assembly 10 is in an upright position, the liquid level detection element 18 is spaced from the lowest point of the mounting chamber 171, and the bottom of the mounting chamber 171 is inclined or recessed. This ensures that even if liquid in the sewage storage chamber 111 accidentally splashes into the mounting chamber 171 due to shaking or other unintentional conditions, the liquid entering the mounting chamber 171 will not directly trigger the liquid level detection element 18. Instead, the space between the liquid level detection element 18 and the lowest point of the mounting chamber 171 can be used to temporarily store the liquid entering the mounting chamber 171. This further reduces the risk of liquid entering the mounting chamber 171 accidentally triggering the liquid level detection element 18, thereby improving the accuracy of liquid level monitoring in the sewage storage chamber 111.

[0186] In one embodiment, when the sewage storage assembly 10 is in an upright position, the liquid level detection element 18 is located at 1 / 3 to 2 / 3 of the upright height of the housing 113. Specifically, the detection head 181 of the liquid level detection element 18 is located at 1 / 3 to 2 / 3 of the upright height of the housing 113. In other words, the distance between the detection head 181 of the liquid level detection element 18 and the bottom of the housing 113 is 1 / 3 to 2 / 3 of the upright height of the housing 113. Thus, by rationally setting the height of the liquid level detection element 18 when the sewage storage assembly 10 is in an upright position, this embodiment rationally controls the maximum liquid storage capacity of the sewage storage assembly 10 when in a tilted position, thereby improving the user experience.

[0187] In one embodiment, if Figure 22 As shown, the distance between the air inlet 112 and the detection head 181 of the liquid level detection element 18 in the extension direction of the recovery pipe 12 is W1 mm, satisfying: 120≤W1≤150. In this way, this embodiment reasonably sets the height of the liquid level detection element 18 when the sewage storage assembly 10 is in an upright state to reasonably control the maximum liquid storage capacity of the sewage storage assembly 10 when it is in an inclined state, which is conducive to improving the user experience. Optionally, W1 can be any value among 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, and 150.

[0188] In one embodiment, when the sewage storage assembly 10 is in a horizontal position, the liquid level detection element 18 is located at 1 / 4 to 2 / 3 of the horizontal height of the housing 113. Specifically, the detection head 181 of the liquid level detection element 18 is located at 1 / 4 to 2 / 3 of the horizontal height of the housing 113. That is, the distance between the detection head 181 of the liquid level detection element 18 and the bottom of the housing 113 is 1 / 4 to 2 / 3 of the horizontal height of the housing 113. Thus, by rationally setting the height of the liquid level detection element 18 when the sewage storage assembly 10 is in a horizontal position, this embodiment rationally controls the maximum liquid storage capacity of the sewage storage assembly 10 in the horizontal position, significantly reducing the risk of excessive liquid level in the sewage storage chamber 111 and minimizing the risk of excessive backflow of dirt into the air intake 112 due to excessive liquid in the sewage storage chamber 111.

[0189] In one embodiment, if Figure 21 As shown, when the dirt storage assembly 10 is in a horizontal position, the distance between the air intake 112 and the liquid level detection element 18 in a direction perpendicular to the surface to be cleaned 20 is W2 mm, satisfying the following relationship: 40 ≤ W2 ≤ 50. Thus, by rationally setting the height of the liquid level detection element 18 when the dirt storage assembly 10 is in a horizontal position, this embodiment effectively controls the maximum liquid storage capacity of the dirt storage assembly 10 in this horizontal position. This significantly reduces the risk of excessive liquid level in the dirt storage chamber 111, minimizing the risk of excessive backflow of dirt into the air intake 112 due to excessive liquid in the dirt storage chamber 111. Alternatively, W2 can be any value among 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, and 50.

[0190] Please also refer to Figure 23 and Figure 24 , Figure 23 This is a structural diagram of another embodiment of the mounting frame of the present application. Figure 24 yes Figure 23 Schematic diagram of the bottom structure of the mounting frame shown.

[0191] In one embodiment, at least one side of the mounting cavity 171 is provided with an open opening 177, and the dirt storage chamber 111 communicates with the mounting cavity 171 through the open opening 177. Unlike the aforementioned embodiment, in which the mounting cavity 171 communicates with the dirt storage chamber 111 via the detection hole 172, this embodiment eliminates the detection hole. Instead, one side of the mounting cavity 171 is open to form the open opening 177. Liquid in the dirt storage chamber 111 enters the mounting cavity 171 through the open opening 177 on the mounting bracket 17 and then contacts the liquid level detection element 18. The liquid level detection element 18 is encased by the mounting bracket 17, reducing the risk of erroneous triggering of the liquid level detection element 18 due to shaking of the liquid in the dirt storage chamber 111 when the liquid level in the dirt storage chamber 111 does not reach the set level, thereby improving the accuracy of liquid level monitoring in the dirt storage chamber 111. In this embodiment, the monitoring accuracy of the liquid level in the dirt storage chamber 111 is guaranteed, which can greatly reduce the risk of the liquid level in the dirt storage chamber 111 being too high, and avoid as much as possible the increased risk of dirt flowing back into the air intake 112 due to excessive liquid in the dirt storage chamber 111.

[0192] The opening 177 of the mounting chamber 171 faces the inner sidewall of the housing 113. A predetermined distance exists between the opening 177 of the mounting chamber 171 and the inner sidewall of the housing 113, forming a liquid inlet gap 1771. The dirt storage chamber 111 communicates with the mounting chamber 171 sequentially through the liquid inlet gap 1771 and the opening 177. Liquid in the dirt storage chamber 111 enters the mounting chamber 171 sequentially through the liquid inlet gap 1771 and the opening 177. The liquid in the dirt storage chamber 111 enters the mounting chamber 171 slowly through the liquid inlet gap 1771 and the opening 177. The liquid in the dirt storage chamber 111 enters the mounting chamber 171 slowly, further reducing the risk of liquid in the dirt storage chamber 111 falsely triggering the liquid level detection element 18, thereby improving the accuracy of liquid level monitoring in the dirt storage chamber 111.

[0193] Furthermore, the predetermined distance is W3 mm, satisfying the following: 0.5 ≤ W3 ≤ 3. By properly setting the flow area of the liquid inlet gap 1771, this embodiment can reasonably control the rate at which liquid in the dirt storage chamber 111 enters the mounting chamber 171. This can both reduce the risk of liquid in the dirt storage chamber 111 falsely triggering the liquid level detection element 18, thereby improving the monitoring accuracy of the liquid level in the dirt storage chamber 111, and ensure that the liquid level detection element 18 promptly reports that the liquid storage volume in the dirt storage chamber 111 has reached its maximum value. Optionally, W3 can be any value selected from 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, and 3.0.

[0194] In one embodiment, when the dirt storage assembly 10 is in an upright position, a drainage hole is provided at the bottom of the mounting cavity 171. This ensures that even if liquid in the dirt storage cavity 111 enters the mounting cavity 171 due to sloshing, the liquid can be drained back into the dirt storage cavity 111 through the drainage hole at the bottom of the mounting cavity 171. This further reduces the risk of liquid entering the mounting cavity 171 falsely triggering the liquid level detection element 18 and improves the accuracy of liquid level monitoring in the dirt storage cavity 111.

[0195] Furthermore, the area of the drainage hole is M mm 2 , satisfying: 10≤M≤20. By rationally setting the area of the drainage hole, this embodiment not only ensures that liquid entering the mounting chamber 171 can be quickly discharged from the drainage hole into the sewage storage chamber 111, greatly preventing liquid entering the mounting chamber 171 from falsely triggering the liquid level detection element 18, thereby ensuring accurate monitoring of the liquid level in the sewage storage chamber 111, but also prevents the drainage hole from being too large, thereby reducing the risk of liquid in the sewage storage chamber 111 entering the mounting chamber 171 due to sloshing, further reducing the risk of liquid in the sewage storage chamber 111 falsely triggering the liquid level detection element 18, and improving the accuracy of monitoring the liquid level in the sewage storage chamber 111. Optionally, M can be any value among 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

[0367] Example 1:

[0368] The cleaning device 30 is a floor scrubber, and is used to clean the surface to be cleaned 20. The dirt storage assembly 10 includes a dirt storage tank 11, which includes a housing 113 and a lid 114. The lid 114 is mounted on top of the housing 113, and the lid 114 and the housing 113 are joined to form a dirt storage chamber 111. The lid 114 is provided with an air intake 112; the air intake 112 is used to extract air from the dirt storage chamber 111 to create a negative pressure environment therein. The dirt storage assembly 10 also includes a recovery pipe 12, which is disposed within the dirt storage chamber 111. The recovery pipe 12 is configured to recover dirt from the surface to be cleaned 20 into the dirt storage chamber 111 under the action of a pressure differential; the recovery pipe 12 extends toward the lid 114. The sewage storage assembly 10 also includes a solid-liquid separator 16, which is arranged at an angle in the sewage storage chamber 111, dividing the sewage storage chamber 111 into a solid sewage storage chamber 1111 on the side near the air intake 112 and a liquid sewage storage chamber 1112 on the side away from the air intake 112. The solid-liquid separator 16 is provided with one or more first separation holes 161. The sewage storage assembly 10 also includes a one-way plate 15, which is rotatably connected to the solid-liquid separator 16 via a rotating shaft 151 to close or open the first separation holes 161. Among them, the sewage storage component 10 has at least an upright state and a lying state; when the sewage storage component 10 is in the upright state, the box cover 114 and the box body 113 are arranged up and down in sequence, and the rotation axis 151 of the one-way plate 15 is located below the first separation hole 161, and the one-way plate 15 rotates under the action of gravity to open the first separation hole 161; when the sewage storage component 10 is in the lying state, the box body 113 and the box cover 114 are arranged horizontally adjacent to each other, and the rotation axis 151 of the one-way plate 15 is located above the first separation hole 161.

[0369] When the user needs to use the cleaning device 30 to clean low areas such as under a bed, under a sofa, under a table or chair, the dirt storage assembly 10 is in a lying state. When the user pushes the cleaning device 30 forward, the dirt storage assembly 10 moves forward, and the liquid in the solid dirt storage chamber 1111 passes through the first separation hole 161 and acts on the one-way plate 15, so that the one-way plate 15 rotates in the direction away from the solid-liquid separator 16 under the impact of the liquid in the solid dirt storage chamber 1111 to open the first separation hole 161, and the liquid enters the liquid dirt storage chamber 1112 through the first separation hole 161, thereby realizing the recovery of liquid dirt and weakening the surge to a certain extent through the first separation hole 161; when the user pulls the cleaning device 30 backward, the dirt storage assembly 10 retreats, and the liquid in the liquid dirt storage chamber 1112 acts on the one-way plate 15, so that the one-way plate 15 rotates toward the solid-liquid separator 16 under the impact of the liquid in the liquid dirt storage chamber 1112 to close the first separation hole 161, and prevent the liquid in the liquid dirt storage chamber 1112 from flowing back to the solid dirt storage chamber 1111.

[0370] Example 2:

[0371] The one-way plate 15 is rotatably connected to the side of the solid-liquid separator 16 facing the liquid dirt storage chamber 1112; when the dirt storage component 10 is in a lying state and moves along the box cover 114 toward the box body 113, the one-way plate 15 rotates under the impact of the inertia of the liquid in the solid dirt storage chamber 1111 to open the first separation hole 161; when the dirt storage component 10 is in a lying state and moves along the box body 113 toward the box cover 114, the one-way plate 15 rotates under the impact of the inertia of the liquid in the liquid dirt storage chamber 1112 to close the first separation hole 161.

[0372] When the user needs to use the cleaning device 30 to clean low areas such as under a bed, under a sofa, under a table or chair, the dirt storage assembly 10 is in a lying state. When the user pushes the cleaning device 30 forward, the dirt storage assembly 10 moves forward, and the liquid in the solid dirt storage chamber 1111 passes through the first separation hole 161 and acts on the one-way plate 15, so that the one-way plate 15 rotates in the direction away from the solid-liquid separator 16 under the impact of the liquid in the solid dirt storage chamber 1111 to open the first separation hole 161, and the liquid enters the liquid dirt storage chamber 1112 through the first separation hole 161, thereby realizing the recovery of liquid dirt and weakening the surge to a certain extent through the first separation hole 161; when the user pulls the cleaning device 30 backward, the dirt storage assembly 10 retreats, and the liquid in the liquid dirt storage chamber 1112 acts on the one-way plate 15, so that the one-way plate 15 rotates toward the solid-liquid separator 16 under the impact of the liquid in the liquid dirt storage chamber 1112 to close the first separation hole 161, and prevent the liquid in the liquid dirt storage chamber 1112 from flowing back to the solid dirt storage chamber 1111.

[0373] Example 3:

[0374] The solid-liquid separator 16 includes an adjacent first separation portion 16c and a second separation portion 16d; when the dirt storage assembly 10 is in a lying state, the first separation portion 16c is closer to the surface to be cleaned 20 relative to the second separation portion 16d, and the first separation portion 16c is provided with one or more first separation holes 161, and the second separation portion 16d is provided with one or more second separation holes 168; wherein, the one-way plate 15 is rotatably connected to the first separation portion 16c.

[0375] When the user pulls back the cleaning device 30, at least part of the liquid in the solid dirt storage chamber 1111 flows along the solid-liquid separator 16 under the action of inertia, in a direction away from the box cover 114 and away from the surface to be cleaned 20. When the liquid flows to the area near the second end 16b of the solid-liquid separator 16, the liquid can flow into the liquid dirt storage chamber 1112. That is, when the liquid flows to the area near the second end 16b of the solid-liquid separator 16, it flows into the liquid dirt storage chamber 1112 through the second separation hole 168 of the second separation portion 16d. This achieves liquid dirt recovery while reducing the amount of liquid in the solid dirt storage chamber 1111, and also reduces the risk of liquid backflowing into the air intake 112.

[0376] Example 4:

[0377] The solid-liquid separator 16 is arranged obliquely relative to the extension direction of the recovery pipe 12. The solid-liquid separator 16 has two opposing ends, a first end 16a and a second end 16b. When the dirt storage assembly 10 is in a flat position, the first end 16a is closer to the surface to be cleaned 20 than the second end 16b. Furthermore, the first end 16a is closer to the air inlet 112 than the second end 16b.

[0378] When the dirt storage assembly 10 is in a flat position, the solid-liquid separator 16 extends away from the box cover 114 and away from the surface to be cleaned 20. When the user pulls back on the cleaning device 30, that is, the dirt storage assembly 10 is in a flat position and moves along the box body 113 toward the box cover 114, at least a portion of the liquid in the solid dirt storage chamber 1111 will flow along the solid-liquid separator 16 away from the box cover 114 and away from the surface to be cleaned 20 due to inertia. This can buffer the surge and extend the flow range of the surge, further weakening the surge and reducing the risk of liquid backflowing into the air intake 112.

[0380] The angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is θ1, which satisfies the following conditions: 40°≤θ1≤60°. By properly setting the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12, it is possible to ensure that the solid-liquid separator 16 can achieve its surge reduction function while also preventing the size of the solid-liquid separator 16 from exceeding the limit. If the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is too small, the solid-liquid separator 16 will not be able to significantly reduce the surge; if the angle between the solid-liquid separator 16 and the extension direction of the recovery pipe 12 is too large, the length of the solid-liquid separator 16 may be too long, which will affect the arrangement of the remaining components in the sewage storage chamber 111.

[0381] Example 6:

[0382] The solid-liquid separator 16 is provided with a connecting portion 164 and a limiting portion 165. The one-way plate 15 is rotatably connected to the connecting portion 164. The limiting portion 165 is used to abut against the one-way plate 15 when the one-way plate 15 rotates away from the solid-liquid separator 16 to limit further rotation of the one-way plate 15.

[0383] Embodiment seven:

[0384] The solid-liquid separator 16 includes a main body 166 and a protrusion 167. The main body 166 has a first surface 1661 facing away from the air inlet 112. The protrusion 167 is connected to the main body 166 and has a second surface 1671 facing away from the air inlet 112. The second surface 1671 is closer to the air inlet 112 than the first surface 1661. The one-way plate 15 is disposed opposite the protrusion 167.

[0385] When the one-way plate 15 closes the first separation hole 161, the second surface 1671 of the protrusion 167 is spaced apart from the one-way plate 15, thereby reducing the risk of dirt being trapped between the one-way plate 15 and the solid-liquid separator 16. This prevents the one-way plate 15 from being unable to completely close the first separation hole 161 due to dirt being trapped between the one-way plate 15 and the solid-liquid separator 16. This reduces the risk of liquid in the liquid dirt storage chamber 1112 flowing back into the solid dirt storage chamber 1111, thereby reducing the risk of liquid in the solid dirt storage chamber 1111 and thus backflowing into the air intake 112.

[0386] The above is a detailed introduction to the cleaning device, its dirt storage component, and the cleaning system provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
