Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a cleaning device. Background Technology

[0002] With the continuous development of cleaning equipment technology, the types of cleaning equipment are becoming increasingly diverse. Among them, floor scrubbers (such as walk-behind floor scrubbers) can help users effectively clean up the debris adhering to the surface to be cleaned, improving the cleaning efficiency of the surface, and are therefore widely used in daily cleaning work.

[0003] In related technologies, a floor scrubber includes a body and a floor brush assembly rotatably connected to the body. A wastewater tank and a motor are sequentially arranged on the body along the direction away from the floor brush assembly. During use, the motor provides suction to the floor brush assembly via the wastewater tank, enabling the floor brush assembly to clean the surface to be cleaned and collect the wastewater back into the wastewater tank.

[0004] However, in some applications, during the use of the aforementioned floor scrubber, the wastewater in the wastewater tank can flow into the motor, causing damage to the motor, affecting the user experience and the lifespan of the floor scrubber. Utility Model Content

[0005] This application provides a cleaning device to address the shortcomings of related technologies.

[0006] This application provides a cleaning device, including a floor brush assembly and a body; the floor brush assembly has a liquid waste chamber and a sludge inlet channel; the floor brush assembly is rotatably connected to the body, and the body has a solid waste chamber and a first negative pressure channel. The solid waste chamber has a sludge inlet and a sludge outlet, the sludge inlet is connected to the sludge inlet channel, the sludge outlet is connected to the liquid waste chamber, and the first negative pressure channel is connected to the solid waste chamber. The solid waste chamber is configured to collect solid impurities in the water-air mixture entering the solid waste chamber through the sludge inlet channel and the sludge inlet, and discharge the wastewater in the water-air mixture in the solid waste chamber to the liquid waste chamber, and discharge the gas in the water-air mixture in the solid waste chamber to the first negative pressure channel.

[0007] In this way, a better three-phase separation effect of solid, liquid, and gas can be achieved for water-air mixtures. At the same time, since the liquid waste chamber is located in the floor brush assembly, the sewage is collected in the liquid waste chamber. On the one hand, this keeps the liquid waste chamber far away from the first negative pressure channel, so that sewage is less likely to flow into the first negative pressure channel, reducing the phenomenon of sewage flowing into the suction component of the cleaning equipment from the first negative pressure channel. On the other hand, during the rotation of the machine body relative to the floor brush assembly, the floor brush assembly remains in contact with the surface to be cleaned, so that the liquid waste chamber does not move due to the rotation of the machine body. This avoids the sewage inlet of the liquid waste chamber from directly facing the suction component in the horizontal direction due to changes in orientation, thereby reducing the phenomenon of sewage sloshing from the liquid waste chamber flowing out of the liquid waste chamber and flowing into the suction component, improving the user experience and extending the service life of the cleaning equipment.

[0008] In one possible implementation, the cleaning device provided in this application further includes a second negative pressure channel, which connects the upper part of the liquid waste chamber and the end of the first negative pressure channel toward the floor brush assembly.

[0009] Thus, by setting up the second negative pressure channel, the gas emission efficiency can be improved; at the same time, since the second negative pressure channel is connected to the upper part of the liquid waste chamber, the sewage in the liquid waste chamber will not easily enter the second negative pressure channel, reducing the phenomenon of sewage in the liquid waste chamber flowing from the second negative pressure channel to the first negative pressure channel.

[0010] In one possible implementation, the cleaning device provided in this application further includes a first exhaust pipe, which connects the upper part of the liquid waste chamber and the end of the first negative pressure channel facing the floor brush assembly, and the first exhaust pipe forms a second negative pressure channel.

[0011] In this way, the first exhaust pipe guides the flow of a small amount of gas in the liquid waste chamber to the first negative pressure channel. Even if the machine body angle changes, it can ensure that the small amount of gas can still be discharged normally, avoiding the gas blockage caused by gas stagnation, and improving the negative pressure stability and the overall working efficiency of the machine.

[0012] In one possible implementation, the cleaning device provided in this application further includes a second exhaust pipe for connecting the upper part of the liquid waste chamber and the outside of the floor brush assembly.

[0013] In this way, the small amount of gas in the liquid waste chamber is directly discharged to the outside of the floor brush assembly through the second exhaust pipe, thus eliminating the need to connect the second exhaust pipe to the first negative pressure channel, avoiding complex pipeline layout, optimizing the discharge path of the small amount of gas in the liquid waste chamber, and making the exhaust structure simpler.

[0014] In one possible implementation, the cleaning device provided in this application further includes a negative pressure component within the floor brush assembly, which connects the upper part of the liquid waste chamber to the outside of the floor brush assembly.

[0015] In this way, the suction provided by the negative pressure component can directly discharge the small amount of gas in the liquid waste chamber to the outside of the floor brush assembly, making it more convenient to use.

[0016] In one possible implementation, the cleaning equipment provided in this application also includes a sewage inlet hose, which connects the sewage inlet and the sewage inlet channel.

[0017] Thus, due to the good flexibility and deformability of the inlet hose, the inlet hose can maintain a stable connection with the inlet and inlet channel during the user's operation of the machine body rotating relative to the floor brush assembly. This allows the inlet hose to guide the flow of the water-air mixture from the inlet channel to the inlet, ensuring that the water-air mixture can enter the solid waste chamber normally and improving the functional stability of the cleaning equipment.

[0018] In one possible implementation, the cleaning device provided in this application has a collection box detachably mounted on the body, and a separator is provided inside the collection box. The separator divides the collection box into a solid waste chamber and a first negative pressure channel. When the body is rotated to a horizontal state relative to the floor brush assembly, the first negative pressure channel is located above the solid waste chamber.

[0019] In this way, the solid waste chamber and the first negative pressure channel are integrated into the collection box, and the collection box is detachably connected to the machine body. This simplifies the overall structure of the cleaning equipment and makes it convenient for users to remove the collection box from the machine body for cleaning or replacement. By setting the first negative pressure channel above the solid waste chamber when the machine body is rotated to a horizontal position relative to the floor brush assembly, the sewage flow path and the gas flow path will not interfere with each other due to the rotation of the machine body, resulting in a more reasonable layout.

[0020] In one possible implementation, the cleaning device provided in this application has at least one vent on the separator, the vent being connected to a first negative pressure channel and a solid waste chamber.

[0021] In this way, the gas in the water-air mixture inside the solid waste chamber can enter the first negative pressure channel through the exhaust port during the cleaning process, and finally be discharged outside the cleaning equipment by the suction component of the cleaning equipment; by setting the exhaust port on the separator, the exhaust structure is simplified, which helps to reduce the space occupied inside the collection box and makes the structure of the collection box more compact.

[0022] In one possible implementation, the cleaning device provided in this application has a waste inlet pipe inside the solid waste chamber, an exhaust port adjacent to one end of the waste inlet pipe, one end of the waste inlet pipe communicating with the waste inlet, and the other end of the waste inlet pipe adjacent to the end of the collection box away from the floor brush assembly.

[0023] In this way, the inlet pipe can be extended along the axis of the machine body, so that the exhaust port is adjacent to one end of the inlet pipe, and the other end of the inlet pipe is adjacent to the end of the collection box away from the floor brush assembly, thus avoiding interference with the exhaust operation of the exhaust port due to the position of the inlet pipe. At the same time, the water-air mixture flowing in from the inlet can be guided through the inlet pipe to the area of ​​the solid waste chamber away from the liquid waste chamber, which helps to extend the settling path of solid impurities in the water-air mixture and improves the solid-liquid separation efficiency.

[0024] In one possible implementation, the cleaning device provided in this application includes a separating component comprising a first support plate, a partition plate, and a second support plate connected in sequence. The periphery of the first support plate is connected to the inner wall of the collection box to divide the interior of the collection box into a first cavity and a second cavity. The sewage inlet communicates with the second cavity through the first cavity. The partition plate and the second support plate are located in the second cavity, and the second support plate is connected to a portion of the inner wall of the collection box. The partition plate and the second support plate divide the second cavity into a solid waste cavity and a first negative pressure channel.

[0025] Thus, by setting the periphery of the first support plate to be connected to the inner wall of the collection box, the interior of the collection box is divided into a first cavity and a second cavity. The water-gas mixture is initially guided through the first cavity, avoiding the water-gas mixture from impacting the partition plate and the second support plate in the second cavity, which helps to improve the structural stability of the separator. Through the reasonable layout of the partition plate and the second support plate, the second cavity is divided into a solid waste cavity and a first negative pressure channel to achieve effective separation of solid, liquid and gas phases.

[0026] In one possible implementation, the cleaning equipment provided in this application has a first support pipe in the collection box that communicates with the sewage inlet, a second support pipe on the first support plate, one of the first support pipe and the second support pipe being inserted into the other, and the second support pipe extending into the solid waste chamber.

[0027] This allows the water-air mixture to smoothly enter the solid waste chamber through the guide channel formed by the first and second support pipes, which helps improve the separation efficiency of the water-air mixture; the connection between the first and second support pipes helps improve the assembly accuracy and structural stability between the separator and the collection box.

[0028] In one possible implementation, the cleaning device provided in this application has one end of the inlet pipe connected to the end of the second support pipe located in the solid waste chamber, and the other end of the inlet pipe connected to the end of the partition plate facing the second support plate, and the other end of the inlet pipe has a notch communicating with the solid waste chamber.

[0029] In this way, the water-air mixture flowing out through the gap in the sewage inlet pipe flows onto the partition plate, which reduces the sewage flow velocity, making it easier for the sewage to concentrate and flow smoothly towards the liquid waste chamber.

[0030] In one possible implementation, the cleaning device provided in this application includes a partition plate comprising a connecting portion and a protrusion connected to the connecting portion. The connecting portion is connected to a first support plate, and the protrusion is connected to a second support plate. The protrusion protrudes in a direction away from the inlet pipe, and the forward projection of the inlet pipe toward the protrusion is located within the protrusion.

[0031] In this way, the protrusions buffer and guide the water-air mixture flowing out of the sewage inlet pipe, thereby reducing the sewage flow rate and improving the solid-liquid separation efficiency. At the same time, it can reduce the splashing of solid impurities in the water-air mixture.

[0032] In one possible implementation, the cleaning device provided in this application has a sewage inlet and a sewage outlet located at one end of the collection box facing the floor brush assembly. When the machine body is rotated to a horizontal state relative to the floor brush assembly, a first negative pressure channel, a sewage inlet, and a sewage outlet are arranged sequentially in the vertical direction, and there is a distance between the sewage outlet in the vertical direction and the inner wall of the collection box adjacent to the sewage outlet.

[0033] This makes the layout of the first negative pressure channel, the inlet and outlet more reasonable. When the machine body rotates to a horizontal position relative to the floor brush assembly, the cleaning equipment can still maintain good liquid flow control. At the same time, the first negative pressure channel is far away from the sewage flow area, which helps to prevent sewage from entering the second negative pressure channel and helps to ensure the safe operation of the suction component of the cleaning equipment.

[0034] In one possible implementation, the cleaning device provided in this application has a distance greater than or equal to 0 mm and less than or equal to 50 mm.

[0035] Thus, providing a reasonable arrangement range for the sewage outlet on the collection box helps to improve the structural compactness of the collection box; at the same time, it helps the sewage to flow smoothly to the sewage outlet under the action of gravity and discharge smoothly, reducing the sewage residue area in the solid waste chamber caused by the dispersion of liquid flow due to excessive distance, i.e., greater than 50mm, which is conducive to the more complete collection of sewage in the liquid waste chamber.

[0036] In one possible implementation, the cleaning device provided in this application further includes a first filter element located inside the solid waste chamber and covering the drain outlet.

[0037] In this way, the first filter element intercepts and collects solid impurities in the water-air mixture in the solid waste chamber, preventing solid impurities from entering the drain outlet and causing blockage. This facilitates the smoother discharge of wastewater from the water-air mixture into the liquid waste chamber after filtration.

[0038] In one possible implementation, the cleaning device provided in this application further includes a box cover and a second filter element. The second filter element is disposed on the box cover, and an exhaust port is formed at one end of the collection box away from the floor brush assembly. The box cover is detachably placed on the exhaust port, and the exhaust port is connected to a first negative pressure channel. The second filter element is used to filter the gas discharged from the box cover through the first negative pressure channel.

[0039] In this way, filtering the gas discharged from the box cover through the first negative pressure channel by the second filter can reduce the blockage of the suction components of the cleaning equipment by solid impurities in the water-air mixture, and reduce the amount of solid impurities discharged into the air with the gas, which is conducive to improving the air quality and environmental cleanliness. In addition, the detachable design of the box cover makes it easier for users to clean the inside of the collection box or replace the second filter, improving the user experience and the convenience of maintaining the cleaning equipment.

[0040] In one possible implementation, the cleaning device provided in this application further includes a seal disposed between the inner wall of the collection box and the separator to seal the gap between the collection box and the separator.

[0041] This effectively prevents gas in the water-air mixture from leaking through the gap between the separator and the collection box, ensuring pressure stability in the first negative pressure channel. At the same time, it prevents solid impurities in the solid waste chamber from flowing through the gap between the separator and the collection box to the floor brush assembly, avoiding blockage of the floor brush assembly or secondary pollution of the surface to be cleaned.

[0042] In one possible implementation, the cleaning device provided in this application has a portion of the outer side of the collection box as a slope, which corresponds to the solid waste chamber. When the machine body rotates to a horizontal state relative to the floor brush assembly, the slope is inclined from the drain outlet toward the first negative pressure channel located above the drain outlet, and there is an angle between the slope and the horizontal plane.

[0043] This design, with its inclined plane, effectively guides the flow of sewage, allowing it to flow smoothly to the discharge outlet under gravity, reducing sewage residue in the solid waste chamber, and improving drainage efficiency.

[0044] In one possible implementation, the cleaning device provided in this application has an included angle greater than or equal to 0° and less than or equal to 30°.

[0045] In this way, while the inclined surface plays a good role in guiding the sewage, it also facilitates the coordinated layout between the collection box and the other components of the cleaning equipment, ensuring the rational design of the collection box structure and making the structure of the collection box integrated into the machine body have good stability.

[0046] In one possible implementation, the cleaning device provided in this application further includes a drain pipe, which connects the drain outlet to the lower part of the liquid waste chamber and is used to drain the sewage in the water-air mixture in the solid waste chamber into the liquid waste chamber; or, the drain pipe connects the drain outlet to the upper part of the liquid waste chamber and is also used to discharge the gas in the liquid waste chamber to the solid waste chamber and the first negative pressure channel in sequence.

[0047] In this way, the drain pipe guides the wastewater in the water-gas mixture to flow into the liquid waste chamber, which helps to discharge the wastewater more smoothly into the liquid waste chamber. The drain pipe also discharges the gas in the liquid waste chamber to the solid waste chamber and the first negative pressure channel in sequence. Therefore, the gas in the liquid waste chamber can be discharged without the need for other pipelines, which can save the internal space of the machine body and make the machine body more compact.

[0048] In one possible implementation, the cleaning device provided in this application has a funnel-shaped outlet and a drain pipe connected to the outlet, with the larger diameter end of the outlet or drain pipe facing the liquid waste chamber.

[0049] This allows the liquid waste chamber to collect wastewater more fully, reduces the amount of wastewater remaining in the solid waste chamber, and lowers the risk of wastewater flowing into the first negative pressure channel from the exhaust port.

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0075] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0076] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0077] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0078] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0079] With the continuous development of cleaning equipment technology, the types of cleaning equipment are becoming increasingly diverse. Among them, floor scrubbers (such as walk-behind floor scrubbers) can help users effectively clean up the debris adhering to the surface to be cleaned, improving the cleaning efficiency of the surface, and are therefore widely used in daily cleaning work.

[0080] In related technologies, a floor scrubber includes a body and a floor brush assembly rotatably connected to the body. A wastewater tank and a motor are sequentially arranged on the body along the direction away from the floor brush assembly. During use, the motor provides suction to the floor brush assembly via the wastewater tank, enabling the floor brush assembly to clean the surface to be cleaned and collect the wastewater back into the wastewater tank.

[0081] However, in some applications, such as cleaning under beds or cabinets, the limited operating space between the floor scrubber and the floor means users need to rotate the machine relative to the brush assembly to achieve a horizontal position, aligning the wastewater tank and motor horizontally. As the user moves the machine back and forth relative to their hand position, the changing position of the wastewater tank causes the inlet to face the motor horizontally. This results in the wastewater sloshing out through the inlet and flowing towards the motor, potentially causing damage and impacting user experience and the machine's lifespan.

[0082] In view of this, the present application provides a cleaning device. The cleaning device comprises a floor brush assembly and a body. The floor brush assembly has a liquid waste chamber and a sludge inlet channel. The floor brush assembly is rotatably connected to the body. The body has a solid waste chamber and a first negative pressure channel. The solid waste chamber has a sludge inlet and a sludge outlet, connected to the sludge inlet channel and the liquid waste chamber, respectively. The first negative pressure channel is connected to the solid waste chamber. In use, the suction component of the cleaning device provides suction to the floor brush assembly. During cleaning, the floor brush assembly collects solid impurities from the water-air mixture entering the solid waste chamber through the sludge inlet channel and sludge outlet. Wastewater from the water-air mixture in the solid waste chamber is discharged to the liquid waste chamber through the sludge outlet. Gas from the water-air mixture in the solid waste chamber is discharged to the first negative pressure channel and then discharged outside the cleaning device via the suction component.

[0083] In this way, a better three-phase separation effect of solid, liquid, and gas can be achieved for water-air mixtures. At the same time, since the liquid waste chamber is located in the floor brush assembly, the sewage is collected in the liquid waste chamber. On the one hand, this keeps the liquid waste chamber far away from the first negative pressure channel, so that sewage is less likely to flow into the first negative pressure channel, reducing the phenomenon of sewage flowing into the suction component from the first negative pressure channel. On the other hand, during the rotation of the machine body relative to the floor brush assembly, the floor brush assembly remains in contact with the surface to be cleaned, so that the liquid waste chamber does not move due to the rotation of the machine body. This avoids the sewage inlet of the liquid waste chamber from directly facing the suction component horizontally due to changes in orientation, thereby reducing the phenomenon of sewage sloshing from the liquid waste chamber flowing out of the liquid waste chamber and flowing into the suction component, improving the user experience and extending the service life of the cleaning equipment.

[0084] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0085] Reference Figures 1 to 7As shown in the embodiment of this application, the cleaning equipment includes a floor brush assembly 110 and a body 120; the floor brush assembly 110 has a liquid waste chamber 111 and a sludge inlet channel 112; the floor brush assembly 110 is rotatably connected to the body 120, and the body 120 has a solid waste chamber 131 and a first negative pressure channel 132; the solid waste chamber 131 has a sludge inlet 1311 and a sludge outlet 1312, and the sludge inlet 1311 is connected to the sludge inlet channel 112. The drain outlet 1312 is connected to the liquid waste chamber 111, and the first negative pressure channel 132 is connected to the solid waste chamber 131. The solid waste chamber 131 is configured to collect solid impurities in the water-air mixture that enters the solid waste chamber 131 through the sewage inlet channel 112 and the sewage inlet 1311, and discharge the sewage in the water-air mixture in the solid waste chamber 131 to the liquid waste chamber 111, and discharge the gas in the water-air mixture in the solid waste chamber 131 to the first negative pressure channel 132.

[0086] It should be noted that the cleaning equipment in this application embodiment can be a handheld cleaning device, such as a handheld floor scrubber. The cleaning device can be used to clean the surface to be cleaned; for example, it can perform dry or wet cleaning depending on the surface. Alternatively, the cleaning device can also be a floor scrubbing robot or any other cleaning device with a liquid waste chamber 111. This application embodiment uses a floor scrubber 100 as an example for illustration.

[0087] Specifically, the cleaning equipment may be equipped with a suction component 190, which provides the working suction required for cleaning and drives the floor brush assembly 110 for cleaning through the principle of negative pressure. When in use, the suction component 190 has a suction port 191, which cooperates with the first negative pressure channel 132 to achieve efficient flow of gas in the water-air mixture. The floor brush assembly 110 is used to contact the surface to be cleaned, such as tile floor, marble floor, etc. The water-air mixture adsorbed by the floor brush assembly 110 is introduced into the solid waste chamber 131 from the inlet 1311 through the inlet channel 112.

[0088] The specific type of the suction component 190 is not limited in this application embodiment. For example, the suction component 190 can be a vacuum pump or a centrifugal fan, and the suction component 190 is detachably installed in the body 120.

[0089] like Figure 1 As shown, the Z direction represents the up-down direction, i.e., the vertical direction; the X direction represents the direction of user movement, i.e., the horizontal direction. The body 120 and the floor brush assembly 110 of the floor scrubber 100 are arranged sequentially along the Z direction. The body 120 and the floor brush assembly 110 are rotatably connected. During use, the floor brush assembly 110 is positioned close to the surface to be cleaned to facilitate contact between the floor brush assembly 110 and the surface to be cleaned.

[0090] By rotating the body 120 relative to the floor brush assembly 110, the body 120 can be... Figure 2 The positions shown and Figure 3 Switching between the positions shown; wherein, the fuselage 120 is in Figure 2 When the position shown is used, combine Figure 4 As shown, the axial direction of the body 120 is consistent with the Z direction. At this time, along the Z direction, there is a first gap between the end of the body 120 away from the floor brush assembly 110 and the side of the floor brush assembly 110 that contacts the surface to be cleaned; the body 120 in... Figure 3 When the position shown is used, combine Figure 5 As shown, the axis of the body 120 is aligned with the X direction. At this time, along the Z direction, there is a second gap between the end of the body 120 away from the floor brush assembly 110 and the side of the floor brush assembly 110 that contacts the surface to be cleaned. The first gap is greater than the second gap.

[0091] Understandably, depending on the location of the surface to be cleaned, the machine body 120 can be rotated relative to the floor brush assembly 110. This allows the floor brush assembly 110 to absorb the water and air mixture, with the end of the machine body 120 away from the floor brush assembly 110 and the side of the floor brush assembly 110 in contact with the surface to be cleaned at any distance between the first distance, the second distance, or the first and second distances. This avoids interference with the cleaning equipment due to limited space in the Z direction, i.e., the longitudinal direction, and achieves a more thorough cleaning of the surface to be cleaned.

[0092] The machine body 120 includes a solid waste chamber 131 and a first negative pressure channel 132. The suction component 190 and the solid waste chamber 131 are arranged sequentially along the axis of the machine body 120. The suction component 190 and the floor brush assembly 110 are located on opposite sides of the solid waste chamber 131. The suction port 191 of the suction component 190 faces the first negative pressure channel 132, which connects the solid waste chamber 131 and the suction port 191. This layout is reasonable, reduces the overall space occupied by the floor scrubber 100, and makes the structure more compact.

[0093] Furthermore, the floor brush assembly 110 may have a placement cavity 101. A liquid waste housing 102 is provided in the placement cavity 101. The liquid waste housing 102 and the sewage inlet channel 112 are spaced apart to avoid mutual interference. A closed liquid waste chamber 111 is formed inside the liquid waste housing 102. An inlet 1021 is opened on the liquid waste housing 102 to communicate with the liquid waste chamber 111. The liquid waste chamber 111 is connected to the sewage outlet 1312 of the solid waste chamber 131 through the inlet 1021. The sewage inlet channel 112 is connected to the sewage inlet 1311 of the solid waste chamber 131.

[0094] After the floor scrubber 100 is started, the solid waste chamber 131 collects solid impurities in the water-air mixture that enters the solid waste chamber 131 through the sewage inlet 112 and the sewage inlet 1311. The sewage in the water-air mixture is discharged to the liquid waste chamber 111, and the gas in the water-air mixture is discharged to the first negative pressure channel 132.

[0095] Specifically, when the axis of fuselage 120 is aligned with the Z-direction, Figure 6 The first path a, the second path b, and the third path c correspond to the flow direction of the water-air mixture before entering the solid waste chamber 131, the flow direction of the sewage in the water-air mixture, and the flow direction of the gas in the water-air mixture, respectively; when the axial direction of the fuselage 120 is consistent with the X direction, Figure 7 The first path a, the second path b, and the third path c correspond to the flow direction of the water-air mixture before entering the solid waste chamber 131, the flow direction of the sewage in the water-air mixture, and the flow direction of the gas in the water-air mixture, respectively. In other words, after the floor scrubber 100 is started, the normal separation of the solid, liquid, and gas phases can still be ensured during the rotation of the operating body 120 relative to the floor brush assembly 110.

[0096] Furthermore, during the rotation of the operating body 120 relative to the floor brush assembly 110, because the floor brush assembly 110 remains in contact with the surface to be cleaned, the liquid waste chamber 111 will not move due to the rotation of the operating body 120, i.e. Figure 4 and Figure 5 As shown, the orientation of the inlet 1021 on the liquid waste casing 102 remains the same before and after the position of the body 120 is switched.

[0097] Among them, such as Figure 4 As shown, the inlet 1021 on the liquid waste housing 102 is opposite to the suction port 191 along the Z direction. It can be understood that the body 120 rotates to draw water from the liquid waste. Figure 4 Switching to the position in the middle Figure 5 During the process of positioning, the sewage in the liquid waste chamber 111 will not be poured into the suction component 190 due to gravity; when the body 120 switches to Figure 5 After the liquid waste chamber 111 is positioned, since the inlet 1021 on the liquid waste housing 102 still faces the Z direction, while the suction port 191 faces the X direction, the inlet 1021 is not directly facing the suction port 191 of the suction component 190 in the X direction, i.e., the horizontal direction. Thus, when the user pushes and pulls the body 120 back and forth to wash the floor in the direction of travel, the sewage in the liquid waste chamber 111 will be horizontally shaken. The flow path of the sewage from the inlet 1021 to the suction port 191 of the suction component 190 will be interfered with by the cavity wall and other structures of the liquid waste chamber 111, thereby reducing the phenomenon of the surge of sewage generated by the shaking flowing out of the liquid waste chamber 111 and into the suction component 190.

[0098] In addition, since the liquid waste chamber 111 is located in the floor brush assembly 110, the distance between the liquid waste chamber 111 and the first negative pressure channel 132 after being arranged on the floor scrubber 100 is relatively large, so that sewage is less likely to flow through the solid waste chamber 131 to the first negative pressure channel 132, thereby reducing the phenomenon of sewage flowing into the suction component 190 from the first negative pressure channel 132.

[0099] In a specific implementation, to facilitate user operation of the floor scrubber 100, the floor scrubber 100 may also include, for example: Figure 1 The handle assembly 200 shown is connected to one end of the body 120. The handle assembly 200 and the floor brush assembly 110 are located at opposite ends of the axis of the body 120. The handle assembly 200 is used for the user to hold and provides operation control functions.

[0100] This layout makes the overall structure of the floor scrubber 100 more slender and streamlined. The body 120 serves as the overall support, connecting the handle assembly 200 and the floor brush assembly 110, making it easier and more labor-saving for users to operate it upright.

[0101] In summary, the cleaning equipment provided in this application embodiment can provide working suction to the floor brush assembly 110 through the suction component 190 of the cleaning equipment during use. During the cleaning process of the surface to be cleaned, the floor brush assembly 110 collects solid impurities in the water-air mixture that enters the solid waste chamber 131 through the dirt inlet channel 112 and the dirt inlet 1311, and discharges the sewage in the water-air mixture in the solid waste chamber 131 to the liquid waste chamber 111 through the drain outlet 1312. The gas in the water-air mixture in the solid waste chamber 131 is discharged to the first negative pressure channel 132 and then discharged out of the cleaning equipment through the suction component 190.

[0102] In this way, a better three-phase separation effect of solid, liquid, and gas can be achieved for water-air mixtures. At the same time, since the liquid waste chamber 111 is set in the floor brush assembly 110, the sewage is collected in the liquid waste chamber 111. On the one hand, this makes the liquid waste chamber 111 far away from the first negative pressure channel 132, so that sewage is less likely to flow into the first negative pressure channel 132, reducing the phenomenon of sewage flowing into the suction component 190 from the first negative pressure channel 132. On the other hand, when the body 120 rotates relative to the floor brush assembly 110, the floor brush assembly 110 remains in contact with the surface to be cleaned, so that the liquid waste chamber 111 will not move due to the rotation of the body 120. This avoids the sewage inlet of the liquid waste chamber 111 from directly facing the suction component 190 in the horizontal direction due to changes in orientation, thereby reducing the phenomenon of sewage sloshing from the liquid waste chamber 111 flowing out of the liquid waste chamber 111 and flowing into the suction component 190, improving the user experience and the service life of the cleaning equipment.

[0103] Considering that in practical applications, when the wastewater in the water-air mixture in the solid waste chamber 131 is discharged into the liquid waste chamber 111, it will carry a small amount of gas with it. In order to more fully discharge the gas in the water-air mixture, refer to... Figure 4 and Figure 5 As shown, in some embodiments, the cleaning device further includes a second negative pressure channel 151, which connects the upper part of the liquid waste chamber 111 and the end of the first negative pressure channel 132 toward the floor brush assembly 110.

[0104] Thus, by setting up the second negative pressure channel 151, the gas emission efficiency can be improved; at the same time, since the second negative pressure channel 151 is connected to the upper part of the liquid waste chamber 111, the sewage in the liquid waste chamber 111 will not easily enter the second negative pressure channel 151, reducing the phenomenon of sewage in the liquid waste chamber 111 flowing from the second negative pressure channel 151 to the first negative pressure channel 132.

[0105] Among them, such as Figure 4 and Figure 5 As shown, by opening a through hole 1022 in the upper part of the liquid waste chamber 111, that is, on the side of the liquid waste housing 102 away from the brush assembly 110 and in contact with the surface to be cleaned, the liquid waste chamber 111 is connected to the second negative pressure channel 151 through the through hole 1022, so that the second negative pressure channel 151 is connected to the upper part of the liquid waste chamber 111.

[0106] For example, when the axial direction of the fuselage 120 is aligned with the Z-direction, a small amount of gas in the liquid waste chamber 111 flows along... Figure 6 The fourth path d flows through the second negative pressure channel 151 to the first negative pressure channel 132; when the axial direction of the fuselage 120 is aligned with the X direction, a small amount of gas in the liquid waste chamber 111 flows along... Figure 7 The fourth path d flows through the second negative pressure channel 151 to the first negative pressure channel 132.

[0107] In a specific implementation, the cleaning equipment also includes a first exhaust pipe 150, which connects the upper part of the liquid waste chamber 111 and the end of the first negative pressure channel 132 facing the floor brush assembly 110, and the first exhaust pipe 150 forms a second negative pressure channel 151.

[0108] In this way, the first exhaust pipe 150 provides a guiding effect for the flow of a small amount of gas in the liquid waste chamber 111 to the first negative pressure channel 132. Even if the angle of the body 120 changes, it can ensure that the small amount of gas can still be discharged normally, avoiding the gas blockage caused by gas stagnation, and improving the negative pressure stability and the overall working efficiency of the machine.

[0109] For example, the first exhaust pipe 150 is a flexible hose, which can be made of silicone or rubber. Thus, the first exhaust pipe 150 has good flexibility and deformability. After the first exhaust pipe 150 connects the liquid waste chamber 111 and the first negative pressure channel 132, it can adapt to positional deviations or angular changes caused by the rotation of the body 120 relative to the floor brush assembly 110, thereby improving spatial adaptability. Furthermore, the flexible hose also has good sealing performance and shock absorption, which can reduce connection loosening caused by vibration of the suction component 190 during the operation of the cleaning equipment, further improving the stability of the gas flow path.

[0110] Meanwhile, by setting the first exhaust pipe 150 as a flexible hose structure, it is easy for users to disassemble and clean, which helps to improve assembly convenience and maintenance efficiency.

[0111] Reference Figures 8 to 10 As shown, in other examples, the cleaning device also includes a second exhaust pipe 160 for connecting the upper part of the liquid waste chamber 111 to the outside of the floor brush assembly 110.

[0112] In this way, the small amount of gas in the liquid waste chamber 111 is directly discharged to the outside of the floor brush assembly 110 through the second exhaust pipe 160, so that the second exhaust pipe 160 does not need to be connected to the first negative pressure channel 132, avoiding complex pipeline layout, optimizing the discharge path of the small amount of gas in the liquid waste chamber 111, and making the exhaust structure simpler.

[0113] in, Figure 10 The first path a, the second path b, the third path c, and the fourth path d correspond to the flow direction of the water-air mixture before entering the solid waste chamber 131, the flow direction of the sewage in the water-air mixture, the flow direction of the gas in the water-air mixture, and the flow direction of the small amount of gas in the liquid waste chamber 111, respectively.

[0114] In practice, the floor scrubber 100 is equipped with a self-cleaning function. When the floor scrubber 100 is not in use, water is sprayed to clean the liquid waste chamber 111 and other components. Since the second exhaust pipe 160 is directly connected to the outside of the floor brush assembly 110, during the self-cleaning process, water entering the liquid waste chamber 111 can reach the inside of the second exhaust pipe 160 and clean it. The second exhaust pipe 160 can also serve as a drainage channel to discharge the cleaned water to the external environment, i.e., outside the floor brush assembly 110, thus preventing the second exhaust pipe 160 from developing an odor due to long-term use.

[0115] In some examples, a negative pressure element (not shown) is also provided inside the floor brush assembly 110, which is used to connect the upper part of the liquid waste chamber 111 and the outside of the floor brush assembly 110.

[0116] In this way, the suction provided by the negative pressure component can directly discharge the small amount of gas in the liquid waste chamber 111 to the outside of the floor brush assembly 110, making it more convenient to use.

[0117] Reference Figure 4 As shown, in a specific example, the cleaning equipment also includes a wastewater inlet hose 170, which connects the wastewater inlet 1311 and the wastewater inlet channel 112.

[0118] Thus, because the inlet hose 170 has good flexibility and deformation ability, during the process of the user operating the machine body 120 to rotate relative to the floor brush assembly 110, the inlet hose 170 can maintain a stable connection with the inlet port 1311 and the inlet channel 112. This allows the inlet hose 170 to guide the flow of the water-air mixture from the inlet channel 112 to the inlet port 1311, ensuring that the water-air mixture can enter the solid waste chamber 131 normally and improving the functional stability of the cleaning equipment.

[0119] In addition, the inlet hose 170 has good sealing performance and shock absorption effect, which can reduce the loosening of the connection caused by the vibration of the suction component 190 during the operation of the cleaning equipment, and further improve the stability of the flow path of the water-air mixture. At the same time, by setting the first exhaust pipe 150 as a hose structure, it is convenient for users to disassemble and clean, which helps to improve assembly convenience and maintenance efficiency.

[0120] Continue to refer to Figure 4 As shown, in a specific implementation, the cleaning equipment also includes a drain pipe 113, which connects the drain outlet 1312 to the lower part of the liquid waste chamber 111. The drain pipe 113 is used to discharge the sewage in the water-air mixture in the solid waste chamber 131 into the liquid waste chamber 111.

[0121] The lower part of the liquid waste chamber 111 is the inlet 1021 on the liquid waste shell 102 mentioned above.

[0122] Thus, the drain pipe 113 provides a guiding function for the sewage in the water-air mixture to flow into the liquid waste chamber 111, which helps to discharge the sewage into the liquid waste chamber 111 more smoothly.

[0123] Alternatively, in practical applications, the drain pipe 113 can be connected to the drain outlet 1312 and the upper part of the liquid waste chamber 111. The drain pipe 113 is also used to discharge the gas in the liquid waste chamber 111 to the solid waste chamber 131 and the first negative pressure channel 132 in sequence.

[0124] In this way, the gas in the liquid waste chamber 111 is discharged sequentially to the solid waste chamber 131 and the first negative pressure channel 132 through the drain pipe 113. Thus, the gas in the liquid waste chamber 111 can be discharged without the need for other pipelines, which can save the internal space of the body 120 and make the body 120 more compact.

[0125] The diameter of the drain pipe 113 can be designed to be larger to ensure that the gas in the liquid waste chamber 111 can flow more smoothly to the first negative pressure channel 132.

[0126] For example, the drain pipe 113 is a flexible hose, which can be made of silicone or rubber. Thus, the drain pipe 113 has good flexibility and deformability. After the drain pipe 113 connects the drain outlet 1312 and the liquid waste chamber 111, the drain outlet 1312 and the liquid waste chamber 111 can adapt to positional deviations or angular changes caused by the rotation of the machine body 120 relative to the floor brush assembly 110, thereby improving spatial adaptability. In addition, the flexible hose also has good sealing performance and shock absorption effect, which can reduce connection loosening caused by the vibration of the suction component 190 during the operation of the cleaning equipment, further improving the stability of the sewage flow path.

[0127] Meanwhile, by setting the drain pipe 113 to a flexible hose structure, it is easy for users to disassemble and clean, which helps to improve assembly convenience and maintenance efficiency.

[0128] Reference Figures 1 to 11 As shown, in some embodiments, a collection box 130 is detachably provided on the body 120, and a separator 140 is provided inside the collection box 130. The separator 140 divides the collection box 130 into a solid waste chamber 131 and a first negative pressure channel 132. When the body 120 is rotated to a horizontal state relative to the floor brush assembly 110, the first negative pressure channel 132 is located above the solid waste chamber 131.

[0129] In this way, the solid waste chamber 131 and the first negative pressure channel 132 are integrated into the collection box 130, and the collection box 130 is detachably connected to the body 120. This simplifies the overall structure of the cleaning equipment and makes it convenient for users to remove the collection box 130 from the body 120 for cleaning or replacement. By setting the first negative pressure channel 132 above the solid waste chamber 131 when the body 120 is rotated to a horizontal position relative to the floor brush assembly 110, the sewage flow path and the gas flow path will not interfere with each other due to the rotation of the body 120, resulting in a more reasonable layout.

[0130] Among them, the horizontal state is Figure 5 The axis of the fuselage 120 is aligned with the X direction, and the first negative pressure channel 132 is located above the solid waste chamber 131 along the Z direction.

[0131] For example, the body 120 is provided with an installation area that matches the collection box 130. The collection box 130 is located on the installation area. The collection box 130 and the body 120 can be detachably connected by means of sliding rail and groove, snap-fit ​​or threaded knob connection, etc. The embodiments of this application do not limit this.

[0132] Reference Figure 6 , Figure 7 and Figure 12 As shown, in some examples, the separator 140 has at least one vent 1422, which connects the first negative pressure channel 132 and the solid waste chamber 131.

[0133] In this way, the gas in the water-air mixture in the solid waste chamber 131 can enter the first negative pressure channel 132 through the exhaust port 1422 during the cleaning process, and finally be discharged outside the cleaning equipment by the suction component 190. By setting the exhaust port 1422 on the separator 140, the exhaust structure is simplified, which helps to reduce the space occupied inside the collection box 130 and makes the structure of the collection box 130 more compact.

[0134] In specific implementation, the number and shape of the exhaust holes 1422 can be set according to actual needs, and this application embodiment does not limit this. For example, there can be one exhaust hole 1422, or there can be two or more, such as... Figure 12 As shown, four vent holes 1422 are formed on the separator 140 at intervals; the vent holes 1422 can be circular holes, elliptical holes or square holes, etc.

[0135] Reference Figures 6 to 12 As shown, in some embodiments, the solid waste chamber 131 has a sewage inlet pipe 180, an exhaust port 1422 is adjacent to one end of the sewage inlet pipe 180, one end of the sewage inlet pipe 180 is connected to the sewage inlet 1311, and the other end of the sewage inlet pipe 180 is adjacent to the end of the collection box 130 away from the floor brush assembly 110.

[0136] In this way, the inlet pipe 180 can be extended along the axial direction of the body 120, so that the exhaust port 1422 is adjacent to one end of the inlet pipe 180, and the other end of the inlet pipe 180 is adjacent to the end of the collection box 130 away from the floor brush assembly 110, so as to avoid the position of the inlet pipe 180 interfering with the exhaust operation of the exhaust port 1422. At the same time, the water-air mixture flowing in from the inlet port 1311 can be guided through the inlet pipe 180 to the area of ​​the solid waste chamber 131 away from the liquid waste chamber 111, which is beneficial to extending the sedimentation path of solid impurities in the water-air mixture and improving the solid-liquid separation efficiency.

[0137] The vent 1422 is located below the end of the collector that faces away from the brush assembly 110, and the inlet pipe 180 is located between the vent 1422 and the end of the collector that faces away from the brush assembly 110. It can be understood that one end of the inlet pipe 180 is the inlet 1021 of the water-air mixture, and the other end is the outlet of the water-air mixture. After the water-air mixture enters the solid waste chamber 131 from the outlet, the sedimentation path of solid impurities in the water-air mixture during its discharge to the liquid waste chamber 111 includes the distance between the outlet and inlet 1021 of the inlet pipe 180. Through the sufficient flow of the water-air mixture, the solid waste chamber 131 achieves a better collection effect on the solid impurities in the water-air mixture.

[0138] Reference Figures 4 to 12 As shown, in some embodiments, the separator 140 includes a first support plate 141, a partition plate 142, and a second support plate 143 connected in sequence. The periphery of the first support plate 141 is connected to the inner wall of the collection box 130 to divide the interior of the collection box 130 into a first cavity 103 and a second cavity 104. The sewage inlet 1311 communicates with the second cavity 104 through the first cavity 103. The partition plate 142 and the second support plate 143 are located inside the second cavity 104, and the second support plate 143 is connected to part of the inner wall of the collection box 130. The partition plate 142 and the second support plate 143 divide the second cavity 104 into a solid waste chamber 131 and a first negative pressure channel 132.

[0139] Thus, by setting the periphery of the first support plate 141 to correspond to the inner wall of the collection box 130, the interior of the collection box 130 is divided into sections as follows: Figure 7 The first cavity 103 and the second cavity 104 shown are used to initially guide the water-gas mixture through the first cavity 103, so as to avoid the water-gas mixture from impacting the partition plate 142 and the second support plate 143 in the second cavity 104, which is conducive to improving the structural stability of the separator 140. Through the reasonable arrangement of the partition plate 142 and the second support plate 143, the second cavity 104 is divided into a solid waste cavity 131 and a first negative pressure channel 132 to achieve effective separation of solid, liquid and gas phases.

[0140] When the body 120 rotates to a horizontal position relative to the floor brush assembly 110, along... Figure 5 In the X direction, the first support plate 141 is located to the left of the partition plate 142 and the second support plate 143; along Figure 5 In the Z direction, the second support plate 143 forms a first negative pressure channel 132 in the upper region of the second cavity 104 and a solid waste cavity 131 in the lower region, so that the first negative pressure channel 132 is located above the solid waste cavity 131.

[0141] It is understandable that by setting the second support plate 143 to connect with part of the inner wall of the collection box 130, the second support plate 143 is prevented from interfering with the flow of gas from the first negative pressure channel 132 to the suction member 190.

[0142] In practice, the support components can be integrally molded to ensure good connection reliability between the first support plate 141, the partition plate 142, and the second support plate 143. The periphery of the first support plate 141 and the inner wall of the collection box 130, and the second support plate 143 and a portion of the inner wall of the collection box 130, can be connected via an embedded fit such as a groove-boob.

[0143] In a specific implementation, the cleaning equipment also includes a seal 1412, which is disposed between the inner wall of the collection box 130 and the separator 140 to seal the gap between the collection box 130 and the separator 140.

[0144] In this way, gas in the water-air mixture can be effectively prevented from leaking through the gap between the separator 140 and the collection box 130, ensuring the pressure stability in the first negative pressure channel 132; at the same time, it can prevent solid impurities in the solid waste chamber 131 from flowing through the gap between the separator 140 and the collection box 130 to the floor brush assembly 110, avoiding solid impurities from clogging the floor brush assembly 110 or causing secondary pollution to the surface to be cleaned.

[0145] Among them, combined Figure 5 and Figure 12 As shown, the sealing element 1412 is disposed between the inner wall of the collection box 130 and the separator 140, that is, the sealing element 1412 is disposed between the inner wall of the collection box 130 and the periphery of the first support plate 141, thereby sealing the gap between the collection box 130 and the separator 140.

[0146] The specific type of the seal 1412 is not limited in the embodiments of this application. For example, the seal 1412 can be an O-ring, a lip seal, a sponge strip, etc.

[0147] Reference Figure 4 and Figure 6 As shown, in some examples, the collection box 130 has a first support pipe 134 communicating with the sewage inlet 1311, and a second support pipe 1411 is provided on the first support plate 141. One of the first support pipe 134 and the second support pipe 1411 is inserted into the other, and the second support pipe 1411 extends into the solid waste chamber 131.

[0148] In this way, the water-air mixture can smoothly enter the solid waste chamber 131 through the guide channel formed by the first support pipe 134 and the second support pipe 1411, which is beneficial to improving the separation efficiency of the water-air mixture; the insertion of the first support pipe 134 and the second support pipe 1411 is beneficial to improving the assembly accuracy and structural stability between the separator 140 and the collection box 130.

[0149] Combination Figure 4 and Figure 6 As shown, the first support pipe 134 and the inlet hose 170 are located on both sides of the inlet 1311, and the first support pipe 134 is located inside the first cavity 103 of the collection box 130. In a specific implementation, the periphery of the first support pipe 134 can be connected to the periphery of the inlet hose 170 through a sealing ring, and the sealing ring is located between the first support pipe 134 and the inlet 1311, so as to seal the gaps between the first support pipe 134 and the inlet 1311, and between the first support pipe 134 and the inlet hose 170, so that the water-air mixture flowing out of the inlet hose 170 can completely flow into the first support pipe 134 through the inlet 1311, avoiding leakage.

[0150] Furthermore, one end of the sewage inlet pipe 180 is connected to the end of the second support pipe 1411 located in the solid waste chamber 131, and the other end of the sewage inlet pipe 180 is connected to the end of the partition plate 142 facing the second support plate 143. The other end of the sewage inlet pipe 180 has a notch 181 communicating with the solid waste chamber 131.

[0151] Thus, the water-air mixture flowing out through the gap 181 of the sewage inlet pipe 180 flows onto the partition plate 142, which reduces the sewage flow rate and facilitates the sewage to flow in a concentrated and stable manner toward the liquid waste chamber 111.

[0152] In a specific example, the partition plate 142 includes a connecting portion 1421 and a protrusion 1423 connected to the connecting portion 1421. The connecting portion 1421 is connected to the first support plate 141, and the protrusion 1423 is connected to the second support plate 143. The protrusion 1423 protrudes in a direction away from the sewage inlet pipe 180, and the forward projection of the sewage inlet pipe 180 toward the protrusion 1423 is located inside the protrusion 1423.

[0153] Thus, the protrusion 1423 acts as a buffer and guide for the water-air mixture flowing out of the sewage inlet pipe 180, thereby reducing the sewage flow rate and improving the solid-liquid separation efficiency. At the same time, it can reduce the splashing of solid impurities in the water-air mixture.

[0154] Among them, combined Figure 5 and Figure 12 As shown, when the body 120 rotates to a horizontal position relative to the floor brush assembly 110, along... Figure 5In the X direction, the connecting part 1421 and the protrusion 1423 are arranged in sequence, and the exhaust hole 1422 is opened on the connecting part 1421.

[0155] In some embodiments, the inlet 1311 and the outlet 1312 are located at one end of the collection box 130 facing the floor brush assembly 110. When the body 120 is rotated to a horizontal state relative to the floor brush assembly 110, the first negative pressure channel 132, the inlet 1311 and the outlet 1312 are arranged sequentially in the vertical direction, and there is a distance between the outlet 1312 and the inner wall of the collection box 130 adjacent to the outlet 1312 in the vertical direction.

[0156] This makes the layout of the first negative pressure channel 132, the sewage inlet 1311 and the sewage outlet 1312 more reasonable. When the body 120 rotates to a horizontal state relative to the floor brush assembly 110, the cleaning equipment can still maintain good liquid flow control capability. At the same time, the first negative pressure channel 132 is far away from the sewage flow area, which helps to prevent sewage from entering the second negative pressure channel 151 and is conducive to ensuring the safe operation of the suction component 190.

[0157] In practice, the distance is greater than or equal to 0mm and less than or equal to 50mm.

[0158] Thus, providing a reasonable arrangement range for the discharge port 1312 on the collection box 130 is beneficial to improving the structural compactness of the collection box 130; at the same time, it helps the sewage to flow smoothly to the discharge port 1312 under the action of gravity and discharge smoothly, reducing the formation of sewage residue area in the solid waste chamber 131 due to the dispersion of liquid flow when the distance is too large, that is, greater than 50mm, which is conducive to the more complete collection of sewage in the liquid waste chamber 111.

[0159] This application does not limit the specific value of the distance in its embodiments. For example, when the body 120 is rotated to a horizontal position relative to the floor brush assembly 110, the distance between the vertical drain outlet 1312 and the inner wall of the collection box 130 adjacent to the drain outlet 1312 is 0 mm, thereby reducing the deposition of sewage near the drain outlet 1312. Alternatively, the distance can be set to 20 mm, 30 mm, 45 mm, or 50 mm.

[0160] Reference Figure 4 As shown, in some examples, the cleaning device also includes a first filter 1313 located within the solid waste chamber 131 and covering the drain outlet 1312.

[0161] In this way, the first filter element 1313 intercepts and collects solid impurities in the water-air mixture in the solid waste chamber 131, preventing solid impurities from entering the drain outlet 1312 and causing blockage. This facilitates the smoother discharge of wastewater in the water-air mixture into the liquid waste chamber 111 after filtration.

[0162] The specific type of the first filter element 1313 is not limited in the embodiments of this application. Exemplarily, the first filter element 1313 is a detachable structure, such as a mesh filter element, a filter plate filter element, or a multi-layer composite filter sheet. This facilitates the cleaning or replacement of the first filter element 1313.

[0163] The drain outlet 1312 may include a first sub-drain outlet 1301 and a second sub-drain outlet 1302 connected in sequence. The first sub-drain outlet 1301 is located at the end of the collection box 130 facing the floor brush assembly 110. When the separator 140 is placed inside the collection box 130, the first support plate 141 of the separator 140 is positioned opposite to the end of the collection box 130 facing the floor brush assembly 110. By placing the second sub-drain outlet 1302 on the first support plate 141, the second sub-drain outlet 1302 and the first sub-drain outlet 1301 are positioned opposite each other to form a communication. When the first filter element 1313 is placed over the drain outlet 1312, the first filter element 1313 may be detachably connected to the first support plate 141. In this way, the sewage is filtered first when it passes through the second sub-drain outlet 1302, and then flows into the liquid waste chamber 111 through the first sub-drain outlet 1301.

[0164] Reference Figure 4 , Figure 5 and Figure 11 As shown, in some embodiments, the cleaning device further includes a cover 135 and a second filter 1351. The second filter 1351 is disposed on the cover 135. The end of the collection box 130 away from the floor brush assembly 110 forms an exhaust port 133. The cover 135 is detachably placed on the exhaust port 133. The exhaust port 133 is connected to the first negative pressure channel 132. The second filter 1351 is used to filter the gas discharged from the cover 135 through the first negative pressure channel 132.

[0165] Thus, by filtering the gas discharged from the box cover 135 through the first negative pressure channel 132 via the second filter element 1351, the blockage of the suction element 190 by solid impurities in the water-air mixture can be reduced, and the amount of solid impurities discharged into the air with the gas can be reduced, which is conducive to improving the air quality and environmental cleanliness. In addition, the detachable design of the box cover 135 makes it easier for users to clean the inside of the collection box 130 or replace the second filter element 1351, improving the user experience and the convenience of maintaining the cleaning equipment.

[0166] The end of the box cover 135 that forms the exhaust port 133 with the collection box 130 can be detachably connected by means of snap-fit ​​or threaded connection. The suction port 191 of the suction component 190 faces the box cover 135 and is connected to the first negative pressure channel 132 through the exhaust port 133. The second filter component 1351 can be detachably connected to the box cover 135 by means of snap-fit ​​or plug-in connection. This application embodiment does not limit this.

[0167] In a specific implementation, the second filter element 1351 can be set as a HEPA filter assembly. It is understood that the filter medium of the HEPA filter assembly is made of ultra-fine glass fiber, synthetic fiber (such as polypropylene) or natural fiber. In addition to filtering out moisture in the gas discharged from the cover 135, it can also effectively remove dust, bacteria and other contaminants from the gas.

[0168] Furthermore, as mentioned above, the separator 140 is disposed within the collection box 130, and the second support plate 143 of the separator 140 is connected to a portion of the inner wall of the collection box 130. Specifically, the second support plate 143 can be connected to the collection box 130 via a cover 135, such as... Figure 11 and Figure 12 As shown, the second support plate 143 can be connected to the box cover 135. After the box cover 135 is detachably placed on the exhaust port 133, the second support plate 143 is located inside the collection box 130.

[0169] Reference Figure 11 As shown, in some examples, part of the outer surface of the collection box 130 is a slope 136, which corresponds to the solid waste chamber 131. When the body 120 is rotated to a horizontal state relative to the floor brush assembly 110, the slope 136 is inclined from the drain port 1312 toward the first negative pressure channel 132 located above the drain port 1312, and the slope 136 has an angle with the horizontal plane.

[0170] This design allows the inclined plane 136 to effectively guide the flow of sewage, facilitating its smooth flow to the discharge outlet 1312 under gravity, reducing sewage residue in the solid waste chamber 131, and improving drainage efficiency.

[0171] Among them, the included angle is greater than or equal to 0° and less than or equal to 30°.

[0172] In this way, while the inclined surface 136 plays a good role in guiding the sewage, it also facilitates the coordinated layout between the collection box 130 and the other components of the cleaning equipment, ensuring the rational design of the structure of the collection box 130 and making the structure of the collection box 130 integrated on the body 120 have good stability.

[0173] For example, the included angle can be 0°, 10°, 15°, 20° or 30°.

[0174] Reference Figure 4 , Figure 5 and Figure 13 As shown, in some embodiments, one of the drain outlet 1312 and the end of the drain pipe 113 connected to the drain outlet 1312 is funnel-shaped, and the large-diameter end of the drain outlet 1312 or the drain pipe 113 faces the liquid waste chamber 111.

[0175] In this way, the liquid waste chamber 111 can collect sewage more fully, reduce the residual sewage in the solid waste chamber 131, and reduce the risk of sewage flowing into the first negative pressure channel 132 from the exhaust port 133.

[0176] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
