[0003] The cleaning equipment in related technologies is mostly robotic vacuum cleaners and mopping robots. These cleaning devices are usually equipped with a wastewater tank to collect the wastewater generated during the cleaning process. However, the wastewater generated during the cleaning process usually contains solid waste. When the wastewater is collected into the wastewater tank, the solid waste settles at the bottom of the tank. Over time, this accumulation can easily clog the drain outlet of the wastewater tank, affecting the user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

The filter element is located in the liquid storage chamber and is positioned above the liquid inlet along the depth direction of the liquid storage chamber. The liquid channel of the filter element is connected to the liquid inlet. Wastewater enters the wastewater box through the liquid outlet of the liquid outlet section. Because the filter element is located above the liquid inlet, the wastewater is pumped up. Then, because the liquid outlet of the liquid outlet section is higher than the filter section, the pumped wastewater can flow towards the filter section by gravity and be filtered by the filter section before flowing to the bottom of the wastewater box. The filter section intercepts solid waste such as hair / fibers within the filter element, preventing them from directly entering the bottom of the liquid storage chamber and depositing. This solves the problem of solid waste deposition at the bottom of the liquid storage chamber and ensures smooth water flow within the liquid storage chamber. The reduction in clogging means that users do not need to frequently clean and unclog the wastewater box, reducing maintenance costs and operational hassles. At the same time, the cleaning equipment can maintain good working condition, improving cleaning efficiency.

[0065] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0066] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0067] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0068] Embodiments of this disclosure provide a cleaning system, such as Figure 1 and Figure 2 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be, for example, a mopping robot, a sweeping robot, or a combined sweeping and mopping robot; the cleaning device 10 may include a device body 30, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 20 is used to dock with the cleaning device 10, allowing it to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, water replenishment, and dust collection on the base station 20.

[0069] In some embodiments, the device body 30 is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0070] In some embodiments, the drive module may include a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body 30. In some embodiments, to enable the cleaning device 10 to move more stably or with greater mobility on the ground, the cleaning device 10 may include one or more steering wheels. The steering wheels may be driven wheels or drive wheels, and their structural forms include, but are not limited to, casters. The steering wheels may be located in front of the drive wheel assembly, and a drive motor provides power to the drive wheel assembly and / or the steering wheels.

[0071] In some embodiments, the cleaning device 10 may be a self-propelled cleaning device. The sensing module may include a position determination device located above the device body 30, a buffer located on the forward portion of the device body 30, and a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, and other sensing devices located at the bottom of the device body 30, providing the control module with various position and motion state information of the device body 30. For example, the forward portion of the device body 30 is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure makes the cleaning device 10 respond to the objects, such as stepping over steps.

[0072] In some embodiments, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0073] In some embodiments, the energy module may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device.

[0074] In some embodiments, the human-machine interface module may include buttons on the main control panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available function options to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, and can provide users with richer and more user-friendly functions.

[0075] In some embodiments, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc., while the wet cleaning module may include cleaning components, a water tank, etc. The cleaning components in the wet cleaning module may be roller mops or tracked mops for mopping and washing the surface to be cleaned.

[0076] The roller mop can be mounted on the equipment body 30 via a mounting bracket, and can clean the area to be cleaned along the travel path of the equipment body 30 under the drive of the equipment body 30. During cleaning, the roller mop is driven by a drive motor to rotate relative to the mounting bracket, and in the process of rotation, it rolls and rubs the surface to be cleaned, thereby efficiently removing dirt. To improve the cleaning efficiency of the roller mop during the rolling and rubbing process, cleaning fluid can be sprayed onto the roller mop, so that the roller mop is wetted by the cleaning fluid before rolling and rubbing the surface to be cleaned, thereby further improving the cleaning efficiency. Similarly, the tracked mop can also be mounted on the equipment body via a mounting bracket, and can be wetted by spraying cleaning fluid before rolling and rubbing the surface to be cleaned.

[0077] like Figures 2-5As shown, when the cleaning equipment 10 includes a wet cleaning module, the equipment body 30 is typically equipped with a detachable wastewater box assembly 40 to collect wastewater generated during the cleaning operation of the wet cleaning module. Specifically, the cleaning component of the wet cleaning module is sprayed with cleaning fluid to mop the surface to be cleaned. After mopping, wastewater remains on the parts of the cleaning component that are on the surface to be cleaned. Before the next mopping of the surface to be cleaned, the wastewater on these parts needs to be scraped off, and the surface can be re-sprayed with cleaning fluid to improve the mopping effect. The wastewater box assembly 40 includes a wastewater box 41 and a water collection component 44. A scraper scrapes the wastewater from the cleaning component into the water collection tank 441 of the water collection component 44. A negative pressure device is connected through a negative pressure hole 415 in the wastewater box 41, so that the wastewater in the water collection tank 441 is sucked into the wastewater box 41 by the negative pressure, thus achieving the recovery of the scraped-off wastewater.

[0078] like Figure 5 As shown, the sewage outlet 414 of the sewage box 41 can be located at the bottom of the side wall of the sewage box 41. The sewage box assembly 40 is also provided with a sewage discharge assembly 42, which can be used to block and open the sewage outlet 414. The sewage discharge assembly 42 may include a rotating member 421, an elastic member, and a sealing member 422. The rotating member 421 is rotatably mounted on the sewage box assembly 40, and the sealing member 422 is located on the rotating member 421. Under the elastic force of the elastic member, the rotating member 421 can drive the sealing member 422 to block the sewage outlet 414. Under the action of external force, the rotating member 421 can overcome the elastic force of the elastic member and rotate relative to the sewage box 41, so as to drive the sealing member 422 to open the sewage outlet 414. That is to say, the sewage discharge assembly 42 can keep the sealing member 422 under the pile body that blocks the sewage outlet 414 through the elastic member, and the sewage outlet 414 can be opened by pushing the rotating member 421 to rotate through external force, so as to discharge sewage.

[0079] When the cleaning device 10 needs to discharge wastewater, it can automatically locate the base station 20. After docking with the base station 20, the rotating part 421 on the cleaning device 10 is pushed by the corresponding structure on the base station 20 to open the drain port 414 for wastewater discharge. The wastewater discharged from the wastewater box 41 can be recycled by the base station 20, thus achieving automatic wastewater discharge. Furthermore, after docking with the base station 20, when the cleaning device 10 needs charging, the charging terminal on the cleaning device 10 contacts the charging terminal on the base station 20, enabling the base station 20 to charge the cleaning device 10. When the cleaning device 10 needs to be replenished with clean water and / or cleaning fluid, it can automatically fill with water by connecting the water inlet on the cleaning device 10 to the water supply outlet on the base station 20. Therefore, after docking with the base station 20, the cleaning device 10 can achieve automatic water filling and emptying, automatic charging, and other functions without manual operation by the user, improving the user experience.

[0080] Among them, such as Figure 5 As shown, the wastewater box assembly 40 also includes a side plate 43, which is connected to the wastewater box 41. A sewage discharge assembly 42 is located between the side plate 43 and the wastewater box 41. The side plate 43 has a through hole 431 through which the first end of the rotating component 421 protrudes. The space formed by the side plate 43 and the wastewater box 41 provides effective protection for the sewage discharge assembly 42. The sewage discharge assembly 42 is located inside the side plate 43, preventing direct collisions with external objects and reducing component damage caused by collisions. Simultaneously, the side plate 43 conceals the sewage discharge assembly 42 between itself and the wastewater box 41, exposing only the operating end of the rotating component 421, making the wastewater box assembly 40 more aesthetically pleasing. This avoids the exposed components of the sewage discharge assembly 42 from affecting the overall aesthetics, improves the visual quality of the product, and provides users with a better visual experience. The side plate 43 is detachably connected to the sewage box 41, and the rotating part 421 is rotatably connected to the side plate 43 and the sewage box 41, that is, the rotating shaft of the rotating part 421 can be rotatably set on the side plate 43 and the sewage box 41 respectively.

[0081] However, the wastewater generated during the cleaning process usually contains solid waste. When the wastewater is collected into the wastewater box 41, the solid waste settles at the bottom of the wastewater box 41. Long-term accumulation can easily cause the drain outlet 414 of the wastewater box 41 to become blocked, affecting the user experience.

[0082] In response to the above technical issues, such as Figures 6-10 As shown, an embodiment of this disclosure provides a wastewater box assembly 40, including: a wastewater box 41 and a filter element 45. The wastewater box 41 forms a liquid storage cavity 413 and an inlet 416 communicating with the liquid storage cavity 413. The filter element 45 is located in the liquid storage cavity 413 and is located above the inlet 416 along the depth direction of the liquid storage cavity 413. The filter element 45 includes an outlet portion 451 and a filter portion 452. The outlet portion 451 has a liquid channel communicating with the inlet 416. The outlet end 453 of the outlet portion 451 is higher than the filter portion 452.

[0083] The wastewater box assembly 40 provided in this disclosure has a filter element 45 disposed in the liquid storage cavity 413 of the wastewater box 41. The filter element 45 is located in the liquid storage cavity 413 and is located above the liquid inlet 416 along the depth direction of the liquid storage cavity 413. The liquid channel of the filter element 45 is connected to the liquid inlet 416. Wastewater enters the wastewater box through the inlet 416 and the outlet 453 of the outlet section 451. Since the filter element 45 is located above the inlet 416, the wastewater is pumped up. Then, because the outlet 453 of the outlet section 451 is higher than the filter section 452, the pumped wastewater flows towards the filter section 452 by gravity and is filtered before flowing to the bottom of the wastewater box 41. The filter section 452 intercepts solid waste such as hair / fibers within the filter element 45, preventing them from directly entering and depositing at the bottom of the storage chamber 413. This solves the problem of solid waste accumulation at the bottom of the storage chamber 413, ensuring smooth water flow within the storage chamber 413. Reduced blockages mean users do not need to frequently clean and unclog the wastewater box 41, reducing maintenance costs and operational hassle. Simultaneously, the cleaning equipment 10 maintains good working condition, improving cleaning efficiency.

[0084] In some embodiments, such as Figure 7 As shown, the wastewater box assembly 40 also includes a water collection component 44, on which a water collection trough 441 is formed. The inlet 416 of the wastewater box 41 is connected to the water collection trough 441. The wastewater box 41 has an inlet 416 that connects to the storage chamber 413, and a negative pressure hole 415 is used to connect a negative pressure device. When there is wastewater in the water collection trough 441, a negative pressure can be formed in the wastewater box 41 through the negative pressure hole 415 of the wastewater box 41, thereby using the negative pressure to draw the wastewater at the inlet 416 upward against gravity to the filter element 45 at a higher position. Since the filter element 45 is provided with a filter section 452, the wastewater enters the filter element 45 through the pipe after passing through the water collection trough 441, and then flows into the storage chamber 413 through the filter section 452, which can effectively filter the wastewater entering the wastewater box 41. In addition, the filter element 45 is located inside the storage chamber 413 and will not affect the overall structural stability and airtightness of the wastewater box 41. In some other embodiments, wastewater on the mopping component can be directly sucked from the scraper into the wastewater tank, meaning that the wastewater box assembly 40 may not have a water collection component 44.

[0085] Among them, such as Figure 7As shown, the water collection component 44 and the sewage box 41 can be an integral structure. This integral structure avoids connection gaps between the water collection component 44 and the sewage box 41, effectively preventing sewage leakage from the connection point, ensuring the sealing of the sewage collection and transmission process, reducing equipment contamination and functional failures caused by leakage, and improving the reliability of the sewage box assembly 40. Simultaneously, the integral structure makes the water collection component 44 and the sewage box 41 a robust whole, eliminating the risk of loose connections, allowing them to withstand greater external forces and vibrations, reducing deformation or damage, extending the service life of the components, and lowering the probability of maintenance. Furthermore, the integral structure can be manufactured using a one-time molding process, reducing the number of parts and assembly steps, improving production efficiency, lowering production costs, and making the structure more compact, saving internal installation space, facilitating miniaturization design, and improving the overall layout rationality of the equipment. In other examples, the water collection component 44 and the sewage box 41 can also be separate structures, for example, detachably connected by snap-fit ​​or threaded connections; this disclosure does not limit this.

[0086] In some embodiments, such as Figures 6-8 As shown, the outlet end 453 of the filter element 45 is connected to the inlet 416 of the sewage box 41 through the pipe 46, that is, the pipe 46 forms the liquid channel of the filter element 45.

[0087] The filter element 45 is detachably connected to the wastewater box 41. The pipeline 46 includes a first pipe section 461 and a second pipe section 462. One end of the first pipe section 461 is connected to the inlet 416, and one end of the second pipe section 462 is connected to the outlet 453. The other end of the first pipe section 461 is inserted into the other end of the second pipe section 462. This detachable connection allows users to easily remove the filter element 45 from the wastewater box 41 to clean the filtered solid waste. The insertion design of the pipeline 46 allows for easy separation of the first pipe section 461 and the second pipe section 462 during filter element removal without affecting the removal of the filter element 45. It also facilitates quick connection of the pipeline 46 during installation, making operation convenient. Furthermore, the detachable connection and insertion method do not affect the airtightness of the wastewater box 41. After installation, the tightness of the pipeline 46 connection is ensured, preventing wastewater leakage and ensuring the normal operation of wastewater collection.

[0088] The first pipe section 461 and the water collection component 44 can be integrally formed, and the second pipe section 462 and the filter component 45 can be integrally formed. Therefore, there is only a connection gap at the insertion position of the first pipe section 461 and the second pipe section 462. The insertion position of the first pipe section 461 and the second pipe section 462 is located in the liquid storage chamber 413 of the sewage box 41. Therefore, the disassembly and connection method will not affect the airtightness of the sewage box 41.

[0089] In some embodiments, such as Figure 6 As shown, a one-way valve 48 is provided on the outlet end 453, allowing sewage in the collection tank 441 to enter the sewage box 41 through the one-way valve 48. By setting the one-way valve 48, sewage in the sewage box 41 can only enter the sewage box 41 through the one-way valve 48, effectively preventing sewage in the sewage box 41 from flowing back into the collection tank 441. Especially when the equipment stops working or the negative pressure changes, a certain pressure fluctuation may occur in the sewage box 41. The presence of the one-way valve 48 can prevent sewage backflow and ensure that the sewage flows along the predetermined path. At the same time, the negative pressure device creates negative pressure by evacuating the liquid storage chamber 413 through the negative pressure hole 415. The one-way valve 48 can maintain the pressure difference between the collection tank 441 and the sewage box 41, ensuring that sewage can stably enter the sewage box 41 from the collection tank 441, improving the stability of sewage flow. In addition, the one-way valve 48 has a simple structure, reliable operation, and will not cause excessive resistance to the normal flow of sewage. While ensuring the backflow prevention function, it does not affect the filtration and collection efficiency of sewage.

[0090] The one-way valve 48 may include a floating element disposed on the outlet end 453. The floating element may seal the outlet end 453 by its own gravity or by external force such as an elastic element. When a negative pressure is formed in the storage chamber 413, the one-way valve 48 may open under the action of the negative pressure to draw sewage from the collection tank 441 into the sewage box 41. This disclosure does not limit the specific type of one-way valve 48, and any one-way valve 48 that can achieve the same function may be used.

[0091] In some embodiments, such as Figure 10 As shown, the outlet section 451 is also equipped with an outlet nozzle 454 located in the sewage box 41, and the outlet of the outlet nozzle 454 forms an outlet end 453. The outlet nozzle 454 can guide the sewage flowing in from the pipe 46, so that the sewage can enter the sewage box 41 in a concentrated manner; the outlet nozzle 454 protrudes from the bottom of the outlet section 451, that is, the outlet nozzle 454 raises the height of the outlet end 453, thereby preventing the sewage in the sewage box 41 from flowing back into the pipe 46. A one-way valve 48 can be installed on the outlet nozzle 454 to facilitate the assembly of the one-way valve 48.

[0092] The liquid outlet 454 and the liquid outlet section 451 can be integrally formed, and the second pipe section 462 and the liquid outlet section 451 can be integrally formed, that is, the liquid outlet 454, the filter element 45, and the second pipe section 462 can be integrally formed. The liquid outlet 454 and the second pipe section 462 can be coaxially arranged pipe sections.

[0093] In some embodiments, at least a portion of the filter section 452 is located at the lowest point in the wastewater box 41 along the depth direction of the storage chamber 413. The lowest point in the wastewater box 41 is where wastewater easily accumulates. Positioning at least a portion of the filter section 452 at this location ensures that as much wastewater as possible in the wastewater box 41 is filtered by the filter section 452 before flowing into the storage chamber 413, preventing unfiltered wastewater from remaining in the wastewater box 41 and improving the thoroughness of filtration. Simultaneously, the lowest position of the filter section 452 facilitates the smooth flow of wastewater from the wastewater box 41 into the storage chamber 413 under gravity, reducing wastewater residue in the wastewater box 41. This not only prevents wastewater from stagnating in the wastewater box 41 for extended periods and producing odors but also reduces bacterial growth, maintaining the cleanliness and hygiene of the wastewater box 41.

[0094] In the depth direction of the storage chamber 413, the height of the area near the outlet end 453 in the wastewater box 41 is greater than the height of the filter section 452. Because the height of the area near the outlet end 453 is higher than that of the filter section 452, the wastewater will gradually flow from high to low within the wastewater box 41. This height difference design utilizes gravity to allow the wastewater to flow naturally. During the flow, larger solid particles will first settle in the area near the outlet end 453, while smaller particles will flow with the wastewater to the filter section 452, which helps to improve the filtration efficiency of the filter section 452.

[0095] In some embodiments, such as Figure 11As shown, the bottom of the wastewater box 41 has a stepped structure, including a first stepped surface 4561 and a second stepped surface 4562. In the depth direction of the storage chamber 413, the first stepped surface 4561 is located above the second stepped surface 4562. The outlet 451 and outlet end 453 are located on the first stepped surface 4561, and the filter 452 is located on the second stepped surface 4562. The stepped structure creates a significant height difference. After the wastewater flows from the outlet end 453 into the first stepped surface 4561, it flows along the steps towards the filter 452 on the second stepped surface 4562, slowing down the water at the higher level and directing it to the filter screen at the lower level. This stepped flow path prolongs the flow time of the wastewater in the wastewater box 41, which is beneficial for the full sedimentation of solid waste and improves the filtration efficiency of the filter 452. Meanwhile, the stepped structure makes full use of the space at the bottom of the wastewater box 41, clearly separating the liquid inlet area and the filtration area, making the layout inside the wastewater box 41 more reasonable and orderly. This ensures both smooth liquid inlet and effective filtration, achieving a better filtration effect. In addition, the lower second step surface 4562 forms a collection point for solid waste, facilitating subsequent cleaning of the filter element 45.

[0096] In some embodiments, such as Figure 10 and Figure 11 As shown, the filter section 452 includes multiple filter holes formed at the bottom of the wastewater box 41. The multiple filter holes increase the filtration area, allowing wastewater to flow more quickly into the storage chamber 413, improving filtration speed and efficiency and preventing excessive wastewater retention in the wastewater box 41. By appropriately setting the aperture of the filter holes, solid waste in the wastewater can be screened and filtered, improving the filtration effect. Since the filter holes are located at the bottom of the wastewater box 41, when cleaning the filter section 452 is required, the user can directly rinse the bottom of the wastewater box 41, making operation convenient. Even if a small amount of debris clogs the filter holes, it is easy to clean, ensuring the continuous effectiveness of the filtration function.

[0097] In this embodiment, by providing filter holes at the bottom of the wastewater box 41, the filter section 452 is an integrally formed structure on the filter element 45. In other embodiments, the filter section 452 may also be detachably connected to the filter element 45, and the filter element 45 may be a filter screen or other component with filtering function; this disclosure does not impose any limitations on this.

[0098] In some embodiments, such as Figures 6-8As shown, the wastewater box 41 includes a box body 411 and a cover plate 412. The cover plate 412 covers the box body 411 to form a liquid storage chamber 413. The filter element 45 is detachably connected to the box body 411. The covering structure of the cover plate 412 and the box body 411 can ensure a good seal of the liquid storage chamber 413, prevent wastewater from leaking from the wastewater box 41, avoid contamination or damage to other parts of the equipment, and ensure the normal operation of the equipment. When it is necessary to clean or inspect the inside of the liquid storage chamber 413, it is only necessary to open the cover plate 412. The detachable connection between the filter element 45 and the box body 411 makes it easy to remove the filter element 45 for separate cleaning, further improving the convenience of maintenance, facilitating the assembly and disassembly of the wastewater box 41, and providing convenience for the assembly and maintenance of the equipment.

[0099] In some embodiments, the filter element 45 is provided with at least one gripping structure. For example... Figure 10 and Figure 11 As shown, the filter element 45 is provided with a first gripping structure 4571 and a second gripping structure 4572. The first gripping structure 4571 and the second gripping structure 4572 facilitate the detachable connection between the filter element 45 and the housing 411. The first gripping structure 4571 can be located near the liquid outlet end 453, that is, near the insertion position of the first pipe section 461 and the second pipe section 462, which facilitates the insertion and separation of the first pipe section 461 and the second pipe section 462. The second gripping structure 4572 can be located in the sewage box 41, which is separate from the first gripping structure 4571, which facilitates the application of force to the filter element 45 through different parts, thereby facilitating the disassembly and assembly of the filter element 45.

[0100] In some embodiments, such as Figure 12 As shown, the wastewater box assembly 40 is also equipped with a position sensor 47. When the wastewater box assembly 40 is not installed on the main body 30, or when the wastewater box assembly 40 is assembled with the main body 30, the position sensor 47 can quickly determine whether it is in place, avoiding problems caused by forgetting to install the wastewater box assembly 40 or improper installation, such as wastewater leakage, loose connection of the negative pressure hole 415 affecting the negative pressure effect, etc. If the wastewater box assembly 40 is not installed correctly, it may affect the negative pressure effect of the negative pressure device on the liquid storage chamber 413 through the negative pressure hole 415, thus affecting the intake and collection of wastewater. The position sensor 47 can provide timely feedback on the installation status, ensuring that the equipment operates under correct installation conditions and guaranteeing the normal operation of wastewater collection. At the same time, the presence of the position sensor 47 allows users to intuitively judge the installation status of the wastewater box assembly 40 without relying on experience, reducing operational difficulty and improving the user experience.

[0101] Among them, such as Figure 12As shown, the position sensor 47 is mounted on the filter element 45. Since the filter element 45 is a component in the wastewater box assembly 40 that requires frequent disassembly and cleaning, mounting the position sensor 47 on it allows for a more direct reflection of the filter element 45's installation status. If the filter element 45 is not properly installed, the signal feedback from the position sensor 47 will promptly alert the user, preventing filtration failure due to installation issues and ensuring the normal functioning of the filtration system. Simultaneously, this arrangement integrates the position sensor 47 and the filter element 45, allowing for simultaneous disassembly and installation of the filter element 45, reducing the risk of omissions or damage that may occur when the position sensor 47 is installed alone. Furthermore, since the filter element 45 needs to be mounted on the wastewater box 41, a single position sensor 47 can simultaneously detect whether both the filter element 45 and the wastewater box 41 are properly installed, reducing equipment costs.

[0102] Among them, such as Figure 13 As shown, a mounting groove 458 is formed on the outer wall of the filter element 45, and the position sensor 47 is assembled in the mounting groove 458. The mounting groove 458 provides a dedicated mounting space for the position sensor 47, which can fix and limit the position sensor 47, preventing the position sensor 47 from shifting or falling off due to vibration, shaking or other reasons during the operation of the cleaning equipment 10, thus ensuring the stability of the position sensing. At the same time, the mounting groove 458 is set on the outer wall of the filter element 45, making full use of the existing structural space of the filter element 45, without occupying additional space in the liquid storage chamber 413 or other parts of the sewage box 41, making the overall structure of the sewage box assembly 40 more compact and conducive to the miniaturization design of the equipment. In addition, the mounting slot 458 can provide a certain degree of protection for the position sensor 47, preventing the position sensor 47 from directly contacting the sewage and solid waste in the liquid storage chamber 413, reducing the damage to the position sensor 47 caused by sewage corrosion and garbage collision, and extending the service life of the position sensor 47; when the position sensor 47 malfunctions, it can be directly removed from the mounting slot 458 for replacement, which is simple and convenient to operate and reduces maintenance costs.

[0103] The equipment body 30 also includes a presence detection component, which comprises a presence detector mounted on the equipment body 30 and a position sensor 47 mounted on the wastewater box 41. Once the wastewater box assembly 40 is properly installed on the equipment body 30, the presence detector outputs a presence signal under the action of the position sensor 47. By installing the presence detection component on the equipment body 30 and the position sensor 47 on the wastewater box assembly 40, the presence detector outputs a presence signal after the wastewater box 41 is properly installed. The presence detection component ensures that the equipment will only start its wastewater collection function after the wastewater box 41 is properly installed on the equipment body 30. If the wastewater box 41 is not properly installed or is forgotten to be assembled, the equipment will not start, avoiding problems such as wastewater leakage and negative pressure failure caused by improper installation or forgetting to assemble the wastewater box 41, protecting the equipment and the surrounding environment, and improving the reliability of equipment operation.

[0104] The presence signal can be used as an input signal for the intelligent control system of the equipment, enabling automated control of the equipment. For example, when the wastewater box 41 is installed in place, the equipment automatically starts the negative pressure system; when the wastewater box 41 is removed, the equipment automatically stops the relevant functions, improving the intelligence level of the cleaning equipment 10.

[0105] The position sensing element 47 can be a magnet, and the presence detector can be a Hall sensor. Using a magnet as the position sensing element 47 allows its generated magnetic field to be accurately detected within a certain distance, ensuring the timeliness and accuracy of position sensing. When the wastewater box assembly 40 is installed in place, it can quickly provide a presence signal. Simultaneously, the magnet possesses good physical and chemical stability, is not easily damaged in the humid environment inside the wastewater box 41, has strong corrosion resistance, and can maintain stable magnetism for a long time, ensuring the long-term reliable operation of the position sensing function. Furthermore, the magnet's simple structure and small size facilitate installation in the mounting slot 458 of the filter element 45 without affecting the structure and function of the filter element 45, and also contribute to the overall miniaturization design of the wastewater box assembly 40. In addition, the magnet requires no external power supply, being a passive component, reducing dependence on the equipment's power supply system, lowering energy consumption, and avoiding position sensing failure due to circuit faults. The Hall sensor is highly sensitive to changes in the magnetic field of the magnet, enabling it to accurately detect the magnet's position and thus determine whether the wastewater box 41 is properly installed. Even during equipment operation, vibrations or slight displacements can cause the Hall sensor to reliably detect the magnet's signal, ensuring the accuracy and reliability of the detection results. Furthermore, the Hall sensor is not easily affected by the humid environment or dust inside the wastewater box 41, exhibiting high operational stability; the magnet's magnetic properties are stable and not easily affected by external environmental interference. The combined use of these two components allows for reliable operation in the complex working environment of the cleaning equipment 10, extending the lifespan of the in-situ detection components. In addition, both the Hall sensor and the magnet are low-cost electronic components and devices, resulting in low procurement and manufacturing costs, making them suitable for large-scale application in the cleaning equipment 10. Moreover, their assembly process is simple, requiring no complex debugging procedures, further reducing the production cost of the cleaning equipment 10.

[0106] It is understood that other types of position sensors and presence detectors may also be used as position detection components, such as presence detection through a trigger switch and trigger structure, and this disclosure does not limit this.
