However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0050] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0051] See Figures 1 to 8 As shown, according to a first aspect of an embodiment of this application, a housing assembly 120 is provided, including a housing 122, a plate 1231, a through hole 1233, and a guide 124. The plate 1231 is connected to the housing 122 and is used to divide the housing 122 into a separation space 1221 and a wastewater containing space 1222. The separation space 1221 performs solid-liquid separation of dirt. The through hole 1233 is formed in the plate 1231 to conduct the separation space 1221 and the wastewater containing space 1222. The guide 124 is located in the wastewater containing space 1222 and is used to prevent wastewater from flowing back from the wastewater containing space 1222 to the separation space 1221.

[0052] The housing 122 is divided into a separation space 1221 and a wastewater containing space 1222 by a plate 1231, and the separation space 1221 and the wastewater containing space 1222 are connected by a through hole 1233. This allows solid dirt to remain in the separation space 1221, while wastewater flows into the wastewater containing space 1222 through the through hole 1233. Solid-liquid separation can be achieved by combining a mechanical structure with the gravity flow of liquid, resulting in good separation effect, reduced odor generation, more stable product operation, lower failure rate, and reduced cleaning equipment cost. By setting a guide 124 and positioning it in the wastewater containing space 1222, backflow of wastewater from the wastewater containing space 1222 to the separation space 1221 is prevented, reducing the probability of wastewater backflow and retention in the separation space 1221, and thus reducing odor generation.

[0053] In this technical solution, the box 122 can be divided into a separation space 1221 and a waste liquid containing space 1222 based on the plate 1231. During the operation of the cleaning equipment, dirt is sucked into the separation space 1221 under negative pressure, and then liquid enters the waste liquid containing space 1222 through the through hole 1233 under the action of gravity. Solid waste is stored in the separation space 1221, thereby completing solid-liquid separation.

[0054] In this technical solution, the plate 1231 can be set approximately horizontally, thereby dividing the internal space of the housing 122 into a separation space 1221 arranged vertically and a waste liquid containing space 1222. The separation space 1221 is located above the plate 1231, and the waste liquid containing space 1222 is located below the plate 1231. During normal operation of the cleaning equipment, dirt is first transported to the separation space 1221 under negative pressure, and then liquid can flow into the waste liquid containing space 1222 at the bottom under gravity. Solid waste is stored in the separation space 1221, thus completing solid-liquid separation. A gap can be provided between the edge of the plate 1231 and the inner wall of the housing 122, allowing liquid to enter the waste liquid containing space 1222 through the gap. A through hole 1233 can also be provided on the plate 1231, allowing liquid to enter the waste liquid containing space 1222 through the through hole 1233.

[0055] The through hole 1233 can penetrate the plate 1231 in a roughly vertical direction, so that the sewage in the separation space 1221 above the plate 1231 flows downward through the through hole 1233 into the sewage receiving space 1222 below the plate 1231.

[0056] The housing assembly 120 includes a filter element 1232 disposed on the plate 1231 within the separation space 1221. The height of the area containing the filter element 1232 is higher than the height of the area containing at least one through-hole 1233.

[0057] By mounting the filter element 1232 on the plate 1231 and within the separation space 1221, incoming contaminants can be filtered, enhancing the solid-liquid separation effect and reducing the amount of solid impurities entering the wastewater containing space 1222 through the perforations 1233. By ensuring the area where the filter element 1232 is located is higher than the area where the perforations 1233 are located, the liquid's own gravity allows the filtered liquid to flow smoothly towards the perforations 1233 and into the wastewater containing space 1222, reducing liquid retention in the separation space 1221 and lowering the risk of bacterial growth and odor caused by liquid residue. Simultaneously, the height difference between the areas where the filter element 1232 and the perforations 1233 are located optimizes the liquid flow path, improves separation efficiency, and facilitates subsequent cleaning of solid impurities remaining on the filter element 1232, making maintenance more convenient and further improving the user experience of the cleaning equipment.

[0058] In this technical solution, during the operation of the cleaning equipment, dirt is adsorbed onto the filter element 1232 under negative pressure, and then the liquid enters the waste liquid containing space 1222 through the through hole 1233 under the action of gravity, while solid waste is stored inside the filter element 1232. Based on this, solid-liquid separation can be completed.

[0059] In this technical solution, the design of the plate 1231 is further provided, where the height of the area containing the filter element 1232 is higher than the height of the area containing the through-hole 1233. That is, the side of the plate 1231 facing the separation space 1221 can be designed as non-planar, with a higher height for the area containing the filter element 1232. Based on this, after solid-liquid separation through the filter element 1232, the liquid can more easily flow to the through-hole 1233 due to the height difference of the plate 1231, allowing for more thorough liquid discharge from the plate 1231 and thus the separation space 1221, further reducing odor generation. Simultaneously, it prevents moisture from entering the negative pressure components of the cleaning equipment, making the use of the cleaning equipment safer and more hygienic.

[0060] In this technical solution, the number of through holes 1233 can be one or at least two. When the number of through holes 1233 is at least two, the height of the area where the filter element 1232 is located is higher than the height of the area where at least one through hole 1233 is located, so that liquid can flow out smoothly from the through hole 1233.

[0061] Understandably, a smooth transition can be made between the area where the filter element 1232 is located and the area where the through hole 1233 is located, which is more conducive to the liquid flowing out through the through hole 1233. In other words, the through hole 1233 is designed to resemble a floor drain, which makes it easier to drain the liquid in the separation space 1221.

[0062] Along the length of the housing 122, the filter element 1232 is located in the middle region of the plate 1231, and the through hole 1233 is located in the end region of the housing 122.

[0063] By placing the filter element 1232 in the middle of the plate 1231 along the length of the housing 122 and the through-hole 1233 at the end, the centrally positioned filter element 1232 can collect solid dirt for easy subsequent cleaning. The through-hole 1233, located at the end of the housing 122 along its length, combined with the height difference of the plate 1231, allows gravity to guide liquid more smoothly to the through-hole 1233, reducing residue in the separation space 1221 and improving solid-liquid separation efficiency. This also optimizes internal space utilization, making the structure more compatible with the overall layout of the cleaning equipment, facilitating integration with other components, and improving maintenance convenience.

[0064] By positioning the filter element 1232 in the middle region of the plate 1231 and the through-hole 1233 in the end region of the housing 122, backflow of liquid in the wastewater containing space 1222 into the separation space 1221 caused by equipment movement can be prevented, thus reducing the risk of odor generation. Specifically, in this technical solution, the positions of the filter element 1232 and the through-hole 1233 are further provided: the filter element 1232 is located in the middle region of the plate 1231, and the through-hole 1233 is located in the end region of the housing 122. This design takes into account that during the operation of the cleaning equipment, as the liquid inside the housing 122 increases, combined with the movement of the base assembly 110, the liquid inside the housing 122 will surge, i.e., a wave phenomenon. Positioning the filter element 1232 in the middle region of the plate 1231 and the through-hole 1233 in the end region of the housing 122 allows the liquid in the separation space to flow more easily to the waste liquid receiving space 1222, while preventing the liquid in the waste liquid receiving space 1222 from flowing back into the separation space due to the surge. This results in more thorough solid-liquid separation and further reduces the amount of liquid in the separation space. It also further reduces the probability of moisture contamination of the negative pressure component, especially the motor of the negative pressure component.

[0065] The housing assembly 120 includes an air outlet 126 disposed within the separation space 1221, and an air outlet 1261 formed on the air outlet 126. The housing assembly 120 also includes a wastewater inlet 1251 and is mounted on a housing 122. A through-hole 1233 is disposed in the gas flow path between the wastewater inlet 1251 and the air outlet 1261.

[0066] By providing the inlet 1251, a path is provided for dirt to enter the separation space 1221. By arranging the outlet 126 within the separation space 1221 and forming an outlet 1261 on the outlet 126, airflow within the separation space 1221 can be discharged through the outlet 1261. This creates negative pressure to generate airflow, which then draws in dirt generated during the cleaning process. Combined with the solid-liquid separation unit, this reduces the amount of liquid within the separation space 1221, thereby reducing the probability of liquid entering other components with the airflow, decreasing the risk of equipment malfunction due to liquid corrosion, and extending the equipment's service life. By placing the through-hole 1233 in the gas flow path between the inlet 1251 and the outlet 1261, the airflow can drive the liquid within the separation space 1221 towards the through-hole 1233, accelerating the liquid's entry into the liquid-containing space 1222, improving liquid discharge efficiency, and reducing liquid residue within the separation space 1221. At the same time, when the airflow passes through the hole 1233, it can further separate the entrained water vapor, reduce the probability of liquid entering the air outlet 126 with the airflow, and thus protect the negative pressure component.

[0067] In this technical solution, the air outlet 126 can be connected to the negative pressure component. Based on this, during the operation of the cleaning equipment, the negative pressure component can generate negative pressure, which in turn generates airflow. The airflow draws in the dirt generated during the cleaning process. The dirt flows through the inlet 1251 into the separation space 1221 for solid-liquid separation. Solid waste can be stored in the separation space 1221, while liquid flows by gravity into the waste liquid containing space 1222. The airflow is discharged outside the housing 122 through the air outlet 126, thus forming a closed-loop airflow. It is understood that by arranging the air outlet 126 within the separation space 1221, the amount of liquid in the separation space 1221 is relatively small, reducing the probability of liquid being discharged through the air outlet 126 and the probability of liquid entering the negative pressure component, especially reducing the probability of moisture contaminating the motor of the negative pressure component.

[0068] In one embodiment, the air outlet 126 is disposed on the plate 1231. That is, the air outlet 126 is connected to the plate 1231 and arranged within the separation space 1221. An air outlet 1261 is formed on the air outlet 126, and the air outlet 1261 is also located within the separation space 1221. The air outlet 126 is used to communicate with the negative pressure component, thereby enabling the negative pressure component to provide a negative pressure environment for the housing assembly 120 to draw dirt into the separation space 1221. After solid-liquid separation, the liquid flows into the waste liquid receiving space 1222, and the airflow is discharged outside the housing assembly 120 via the air outlet 126.

[0069] By placing the air outlet 126 on the plate 1231, the airflow path within the separation space 1221 can be made closer to the top surface of the plate 1231. When the liquid-containing gas flows through the plate 1231, the droplets are more easily separated due to gravity settling or contact with the plate 1231, and then flow into the waste liquid receiving space 1222 through the through holes 1233 on the plate 1231, reducing the amount of droplets entering the air outlet 126 with the airflow and improving the gas-liquid separation efficiency.

[0070] The air outlet component 126 can be a separate part, detachably or non-detachably connected to the plate 1231. The air outlet component 126 can also be an integrated structure with the plate 1231, making the internal layout of the housing 122 more compact, reducing the risk of component shaking or displacement, making the position of the air outlet component 126 more stable, improving the smoothness of airflow, and enhancing the reliability of the overall structure.

[0071] In this technical solution, the bottom of the air outlet 126 is connected to the plate 1231, and the air outlet 126 is provided with a flow channel that extends upward to the top of the air outlet 126 to form an air outlet 1261 at the top of the air outlet 126.

[0072] By connecting the bottom of the air outlet 126 to the plate 1231 and extending the air outlet 126 upwards, so that the air outlet 1261 at the top of the air outlet 126 is higher than the surface of the plate 1231, the possibility of liquid entering the air outlet 126 with the airflow can be reduced. Through the upward extension of the flow channel, the airflow, after entering the air outlet 126, must rise vertically to the top air outlet 1261. During this process, residual droplets in the airflow are more easily separated from the airflow due to gravity, settle onto the surface of the plate 1231, and flow into the waste liquid receiving space 1222 through the through-hole 1233, further reducing the probability of droplets entering the negative pressure component with the airflow and lowering the risk of equipment failure.

[0073] By extending the flow channel upwards, an air outlet 1261 is formed at the top of the air outlet 126. This creates a spatial misalignment with the sewage inlet 1251 and the through hole 1233, reducing the possibility of sewage carried by the airflow directly impacting the air outlet 1261, lowering the risk of blockage, and ensuring the stability of the negative pressure environment.

[0074] In this technical solution, the air outlet 126 is generally a hollow cylindrical structure, such as a cylindrical or square cylinder. The air outlet 126 is vertically arranged and is perpendicularly mounted on the plate 1231.

[0075] In this technical solution, the air outlet 126 is fitted to the inner wall of the housing 122, so that there is a sufficiently large gap between the air outlet 126 and the isolation member 127, so that the airflow can flow more smoothly through the flow gap and enter the air outlet 126.

[0076] The housing assembly 120 includes an isolator 127 connected to the plate 1231 and arranged between the filter 1232 and the air outlet 126 to increase the length of the airflow path within the separation space 1221.

[0077] In this technical solution, considering that airflow always flows towards the place with the lowest pressure, after dirt enters the separation space 1221, liquid may enter the air outlet 126 under the action of airflow. Based on this, an isolation member 127 can be set on the plate 1231. The isolation member 127 blocks the filter 1232 and the air outlet 126. Based on this, it is difficult for the liquid that has just entered the separation space 1221 to be directly adsorbed to the air outlet 126. By setting the isolation member 127, the length of the airflow path in the separation space 1221 is increased. With the longer propagation path, most of the liquid will flow into the dirty liquid receiving space 1222 by gravity through the through hole 1233, which can further reduce the probability of water vapor contaminating the negative pressure component and achieve a better air-water isolation effect.

[0078] In the width direction of the housing 122, the sewage inlet 1251 and the air outlet 1261 are located on both sides of the isolation member 127. In the length direction of the housing 122, a flow gap is provided between the isolation member 127 and the inner wall of the housing 122, and a through hole 1233 is provided at the flow gap.

[0079] In the width direction, the separator 127 physically separates the inlet 1251 from the outlet 1261, causing the liquid-containing airflow to enter from the inlet 1251 and then bypass the separator 127 before reaching the outlet 1261, thus extending the airflow path within the separation space 1221. During this process, the liquid droplets carried by the airflow settle more easily due to gravity, reducing the probability of them directly entering the outlet 1261 with the airflow. In the length direction, the flow gap provides a directional flow channel for the separated liquid. The through-hole 1233, located at the flow gap, allows the settled liquid to quickly flow through the hole 1233 into the waste liquid receiving space 1222, further reducing the risk of droplets intruding into the negative pressure component with the airflow and improving the thoroughness of gas-liquid separation.

[0080] The sewage inlet 1251 and the air outlet 1261 are respectively positioned opposite the isolation component 127 at the middle of the length of the housing 122.

[0081] By positioning the inlet 1251 and outlet 1261 opposite each other in the middle of the separator 127, the liquid-containing gas flow entering from the inlet 1251 must detour through the flow gaps at both ends of the separator 127 to reach the outlet 1261. In other words, the airflow path enters from the middle and detours through both ends of the separator 127, extending the flow distance. During this process, droplets settle more easily due to gravity, and as they flow with the airflow towards both ends, they naturally converge at the through-holes 1233 in the flow gaps, flowing into the waste liquid containing space 1222 through the through-holes 1233. This further reduces the probability of droplets entering the outlet 1261 with the airflow, improving the thoroughness of gas-liquid separation.

[0082] In this technical solution, the isolator 127 can be approximately a rectangular flat plate structure, and the isolator 127 is arranged vertically. The bottom of the isolator 127 is connected to the top surface of the plate 1231. The length direction of the isolator 127 is the same as the length direction of the housing 122, and the thickness direction of the isolator 127 is the same as the width direction of the housing 122. Along the length direction of the isolator 127, at least one end of the isolator 127 forms a flow gap with the inner wall of the housing 122.

[0083] In one embodiment, along the length of the housing 122, a flow gap is provided between one end of the isolation member 127 and the inner wall of the housing 122, and a through hole 1233 is provided at the flow gap, and the other end of the isolation member 127 is connected to the inner wall of the housing 122.

[0084] In this embodiment, the airflow enters through the middle of the isolator 127 and passes around one end of the isolator 127, which to some extent extends the flow distance.

[0085] In one embodiment, in the length direction of the housing 122, both ends of the isolation member 127 are provided with a flow gap between them and the inner wall of the housing 122, and a through hole 1233 is provided at each flow gap.

[0086] In this embodiment, both ends of the isolation member 127 are provided with flow gaps and through holes 1233, forming symmetrical flow channels. This allows for a more balanced distribution of airflow and liquid along the length of the housing 122. Compared to unilateral flow, this reduces localized excessive flow velocity or liquid accumulation. The separation space 1221 allows liquid to be diverted through the through holes 1233 on both sides of the flow gap, improving overall separation efficiency. Furthermore, the symmetrically distributed flow gaps and through holes 1233 increase the number of flow paths for liquid and airflow, reducing the probability of a single channel being blocked by solid contaminants. Even if a small amount of blockage occurs in one flow gap, the other side can still operate normally, ensuring continuous and stable operation of the equipment.

[0087] The two overcurrent bays have the same overcurrent area.

[0088] Among them, the via 1233 is formed on the plate 1231 below the flow interval, and the two vias 1233 have the same shape and size.

[0089] In one feasible example, the guide 124 can be disposed around the via 1233 but does not enclose the via 1233. It can prevent the liquid in the sewage containing space 1222 from entering the via 1233 and flowing back to the separation space 1221 through the via 1233 to a certain extent.

[0090] The guide member 124 can be multiple, and the multiple guide members 124 are arranged approximately along the circumference of the through hole 1233, further improving the liquid blocking effect. Specifically, the guide member 124 can be a vertically extending long arc-shaped plate structure or a flat plate structure, etc.

[0091] In another feasible embodiment, one end of the guide 124 can be connected to the plate 1231, the guide 124 can be disposed around the through hole 1233, and the other end extends into the sewage receiving space 1222. In some embodiments, the guide 124 can be integrally formed with the plate 1231 for easy disassembly, which facilitates cleaning and maintenance after use.

[0092] The guide member 124 can be frame-shaped or tubular, with one end connected to the plate 1231 and enclosing the through hole 1233, and the other end extending into the sludge containing space 1222. Based on this, liquid discharged through the through hole 1233 can flow through the guide member 124, and the liquid can be discharged into the lower middle area of ​​the sludge containing space 1222. When the operator uses the cleaning equipment, even if the sewage in the sludge containing space 1222 surges, it will not directly flow back into the separation space 1221 through the through hole 1233, further suppressing sewage backflow.

[0093] In one embodiment, the guide 124 can be a tubular structure, with its first end directly connected to the plate 1231, and the through hole 1233 completely within the enclosure of the guide 124. The first end can be detachably connected to the plate 1231, for example, by snap-fit, which facilitates the disassembly of the guide 124 and the plate 1231 for easy cleaning, and also allows for individual replacement, reducing maintenance and replacement costs. As mentioned earlier, the first end can also be non-detachably connected to the plate 1231, for example, by integral molding, which avoids dirt accumulation at the disassembly connection point and facilitates cleaning and maintenance. The second end of the guide 124 extends downward and into the waste liquid containing space 1222, with sufficient space between the second end and the bottom of the waste liquid containing space 1222 to avoid obstructing liquid flow.

[0094] A liquid channel is provided inside the guide member 124. The liquid channel passes through the guide member 124 along its length. The top of the guide member 124 can be connected to the plate 1231. The liquid channel is connected to the through hole 1233. The bottom end of the guide member 124 extends into the sewage containing space 1222.

[0095] By connecting the top of the guide member 124 to the plate 1231, the liquid channel is connected to the through hole 1233, and the bottom end of the guide member 124 extends into the waste liquid receiving space 1222, forming a closed flow path from the separation space 1221 to the waste liquid receiving space 1222. On the one hand, after being filtered by the separation space 1221, the liquid can flow directionally into the waste liquid receiving space 1222 along the liquid channel, reducing the diffusion or retention of liquid at the through hole 1233 and improving the efficiency of solid-liquid separation. On the other hand, when the cleaning equipment moves, causing liquid surge in the waste liquid receiving space 1222, the presence of the guide member 124 can reduce the probability of liquid backflowing into the separation space 1221 through the through hole 1233, reducing liquid residue in the separation space 1221.

[0096] In this technical solution, the liquid after solid-liquid separation in the separation space 1221 enters the liquid channel of the guide member 124 through the through hole 1233 on the plate 1231 under the action of gravity and / or airflow. Since the liquid channel runs through the length of the guide member 124, the liquid can flow downward along the channel and be discharged into the sewage receiving space 1222 from the bottom end of the guide member 124, reducing the overflow or retention of liquid at the through hole 1233. The bottom end of the guide member 124 extends into the sewage receiving space 1222. When the cleaning equipment moves and causes a surge of liquid in the sewage receiving space 1222, the liquid must enter the guide member 124 and flow upward from the bottom end of the liquid channel to flow back to the through hole 1233. The length of the guide member 124 and the sealing of the liquid channel form a physical barrier, reducing the probability of the surge liquid flowing back to the separation space 1221 through the through hole 1233. Furthermore, by setting the guide 124, the guide 124 cooperates with the plate 1231 with a height difference, so that the liquid flows efficiently to the sewage holding space 1222 under the constraint of gravity and the guide 124, reducing the liquid residue in the separation space 1221, and further suppressing the generation of odor by cooperating with the solid-liquid separation function of the filter 1232.

[0097] The liquid passage is equipped with a check valve and / or a water-blocking rib.

[0098] By installing a check valve and / or baffle in the liquid channel, the probability of surge liquid flowing back to the separation space 1221 through the through hole 1233 is further reduced.

[0099] In this technical solution, the check valve has a one-way flow structure. When liquid in the separation space 1221 flows into the liquid channel through the orifice 1233, the liquid pressure pushes the check valve to open, allowing the liquid to flow downward into the sludge containing space 1222. When the liquid in the sludge containing space 1222 flows upward due to surges or other reasons, the check valve automatically closes under the action of reverse pressure, blocking the liquid from flowing back through the channel to the orifice 1233 and the separation space 1221, thus achieving one-way flow restriction.

[0100] The check valve can be located at the bottom opening of the guide member 124 or inside the liquid passage. The check valve can be bonded and fixed to the guide member 124.

[0101] In this technical solution, water-blocking ribs can be installed on the inner wall of the liquid channel. These ribs can protrude radially inwards from the inner wall of the liquid channel, and the end of the rib furthest from the inner wall can be inclined downwards. When the liquid flows in the forward direction, it can flow downwards along the gaps between the water-blocking ribs without affecting normal drainage. During reverse flow, the water-blocking ribs weaken the upward impact force of the liquid, and simultaneously utilize the liquid's own gravity to allow the backflowing liquid to fall back into the waste liquid receiving space 1222, further reducing the probability of backflow into the through-hole 1233.

[0102] In one embodiment, only a check valve is provided in the liquid passage.

[0103] In one embodiment, only water-blocking ribs are provided in the liquid channel.

[0104] In one embodiment, a check valve and a baffle are simultaneously provided in the liquid channel, with the baffle located below the check valve. The check valve can be located at the through-hole 1233, and the baffle is located in the lower middle section of the liquid channel. This double protection further reduces liquid backflow.

[0105] The area m of the via is between 1 square centimeter and 9 square centimeters, and the cross-sectional area n of the liquid channel is greater than or equal to m.

[0106] In this technical solution, the area parameters of the through-hole 1233 are further provided. The area of ​​the through-hole 1233 is between 1 square centimeter and 9 square centimeters. Based on this, the area of ​​the through-hole 1233 can be controlled within a reasonable range. On the one hand, it can prevent the area of ​​the through-hole 1233 from being too small, preventing liquid from not leaking through the through-hole 1233, but directly passing through the through-hole 1233 and being discharged through the air outlet 126, thus achieving a better air-water separation effect. On the other hand, it can prevent the area of ​​the through-hole 1233 from being too large, which would affect the airflow suction and the cleaning effect.

[0107] The larger the value of the cross-sectional area n of the liquid channel, the less likely the liquid is to flow back into the separation space 1221.

[0108] Along the width direction of the housing 122, the through hole 1233 is located in the middle region of the plate 1231.

[0109] In the width direction of the housing 122, by setting the through-hole 1233 in the middle of the plate 1231, the filter element 1232 is centrally positioned to collect solid dirt, facilitating subsequent cleaning. The through-hole 1233, located in the middle of the width direction of the housing 122, combined with the height difference structure of the plate 1231, allows gravity to guide liquid more smoothly to the through-hole 1233, reducing residue in the separation space 1221 and improving solid-liquid separation efficiency. It also optimizes the use of internal space, making the structure more compatible with the overall layout of the cleaning equipment, facilitating cooperation with other components, and improving maintenance convenience.

[0110] The box 122 can be roughly a hollow cuboid structure. The length direction of the box 122 is the same as the length direction of the plate 1231, and the width direction of the box 122 is the same as the width direction of the plate 1231.

[0111] The plate 1231 faces one side of the separation space 1221, with a trend of being high in the middle and low on the periphery, and the through holes 1233 are distributed on the periphery of the plate 1231.

[0112] By aligning the plate 1231 with a higher center and lower periphery on the side facing the separation space 1221, and with the perforations 1233 distributed around the periphery of the plate 1231, gravity can guide the liquid in the separation space 1221 to flow towards the periphery and enter the waste liquid receiving space 1222 through the perforations 1233. This reduces liquid residue in the center of the plate 1231 and improves solid-liquid separation efficiency. Simultaneously, the perforations 1233 distributed around the periphery prevent liquid in the waste liquid receiving space 1222 from easily flowing back into the separation space 1221 due to equipment movement, reducing the risk of odor generation and facilitating rapid liquid discharge. Combined with the solid-liquid separation function of the filter element 1232, this further optimizes the dirt treatment effect and makes maintenance and cleaning more convenient.

[0113] In one feasible implementation, there are at least two vias 1233, distributed around the periphery of the plate 1231.

[0114] In this technical solution, there can be two or more through holes 1233. This arrangement can improve the drainage efficiency of the separation space 1221, prevent excessive liquid accumulation in the separation space 1221, and further reduce the probability of water vapor contaminating the negative pressure component, especially the probability of water vapor contaminating the motor of the negative pressure component.

[0115] In this technical solution, the vias 1233 are distributed around the periphery of the plate 1231. This arrangement reduces the probability that liquid in the wastewater containing space 1222 will flow back into the separation space 1221 under surge action.

[0116] See Figure 9 As shown, a cleaning device is provided according to a second aspect of the embodiments of this application, including a housing assembly 120 as described above; a base assembly 110, wherein the housing assembly 120 is disposed on the base assembly 110.

[0117] The cleaning device provided in this embodiment includes a base assembly 110 and a housing assembly 120, based on which dirt generated during operation can be transported into the housing assembly 120. In other words, the housing assembly 120 is used to store dirt, such as solid dirt and dirty water. Since the housing assembly 120 is mounted on the base assembly 110, the distance between the housing assembly 120 and the base assembly 110 is very short, resulting in a short dirt transport path. Firstly, it eliminates the need for long pipes, simplifying the structure. Secondly, it greatly reduces the probability of dirt accumulation in areas other than the housing assembly 120, reducing odor generation and making the cleaning device more hygienic to use. Thirdly, it facilitates user cleaning of the housing assembly 120, making the maintenance of the cleaning device more convenient. Fourthly, regarding the counterweight of the cleaning equipment, when the cleaning equipment is used in handheld operation, the housing assembly 120 is placed on the base assembly 110, so that the housing assembly 120 is relatively far away from the user's hand position. This allows the center of gravity of the cleaning equipment to be closer to the base assembly 110, which increases the grip of the cleaning equipment, improves the cleaning ability, and makes it easier for the user to move the cleaning equipment, making the use of the cleaning equipment more effortless.

[0118] It is understood that the base assembly 110 is the main body used to perform cleaning operations. That is, during use, the base assembly 110 is used to contact the ground. The specific form of the base assembly 110 is not limited in this application; for example, the base assembly 110 may include a rotating roller brush, a reciprocating plate-shaped cleaning component, a rotating cleaning disc, etc. These specific embodiments capable of achieving cleaning are all within the protection scope of this application. Compared to the traditional technology that arranges the clean and dirty water tank inside the machine body, this application arranges the tank assembly 120 directly on the base assembly 110, greatly shortening the path of dirt, facilitating dirt collection, inhibiting the generation of bacteria and odors, simplifying the maintenance of the cleaning equipment, and improving the user experience.

[0119] The housing assembly 120 is detachably connected to the base assembly 110.

[0120] In this technical solution, a connection method for the housing assembly 120 is further provided. The housing assembly 120 is detachably connected to the base assembly 110. Based on this, when a large amount of dirt accumulates in the housing assembly 120, such as a large amount of solid dirt and / or sewage, the user can disassemble the housing assembly 120 via the base assembly 110 to pour out the sewage and solid dirt inside the housing assembly 120. Afterwards, the housing assembly 120 can be rinsed with clean water. Finally, the housing assembly 120 can be reassembled into the base assembly 110. This setting facilitates the maintenance of the cleaning equipment, further suppresses the generation of odors, and improves the user experience.
