[0049] Below, refer to Figures 1 to 11 Some embodiments of this application will be described in detail.

[0050] like Figure 1 As shown, this application provides a wastewater tank 100. The wastewater tank 100 is used in cleaning equipment.

[0051] Cleaning equipment refers to equipment used to clean surfaces that need to be cleaned. Cleaning equipment includes, but is not limited to, vacuum cleaners, floor scrubbers, mops, and combined sweeper and mop machines. Surfaces to be cleaned include, but are not limited to, floors, windows, tiles, carpets, tabletops, or the surfaces of other objects and components. This application does not specifically limit the types of cleaning equipment or surfaces to be cleaned.

[0052] In some embodiments of this application, the cleaning device includes a main body, a wastewater tank 100, and a roller brush assembly.

[0053] The main body is the primary supporting and load-bearing component of the cleaning equipment. The cleaning components, movement system, sensing system, control system, drive system, energy system, and human-machine interaction system of the cleaning equipment are all housed within the main body.

[0054] The roller brush assembly is connected to the main body. Driven by the cleaning equipment's moving system, the roller brush assembly moves along the surface to be cleaned. As part of the cleaning system, the roller brush assembly is a key component of the cleaning equipment during the cleaning process.

[0055] Wastewater tank 100 is also part of the cleaning components and is one of the structural components in the cleaning equipment used to collect and store dirt and wastewater generated during the cleaning process. Wastewater tank 100 is located in the main body.

[0056] For example, the roller brush assembly has a suction port. The suction port is connected to the wastewater tank 100. During the cleaning process of the surface to be cleaned, the dirt on the surface and the wastewater generated by the roller brush assembly can be sucked out through the suction port by the suction action of the fan provided in the main body and temporarily stored in the wastewater tank 100.

[0057] like Figures 2 to 4 As shown, the sewage tank 100 includes a tank body 1, a cover 2, and a movable part 3.

[0058] The tank 1 is the outer shell of the sewage tank 100, and an internal cavity 10 is formed for containing sewage and for containing some functional components.

[0059] In this embodiment, the tank 1 is generally cylindrical, with the side near the main body being generally flat and the side away from the main body being generally curved. This allows the sewage tank 100 to fit better against the main body when installed on the flatter side. The curved portion of the tank 1 is also easier for the user to grip, making it easier for the user to assemble and disassemble the sewage tank 100.

[0060] Of course, those skilled in the art will understand that in some other embodiments, the box 1 may also be in the form of a cuboid, a cylinder, or any other suitable shape. This application does not specifically limit the shape of the box 1.

[0061] For example, the tank 1 can be made of a light-transmitting material. This allows the user to easily observe the water level and dirt condition in the wastewater tank 100, facilitating timely emptying of wastewater or cleaning of the wastewater tank 100. The light-transmitting material can be fully light-transmitting or semi-light-transmitting.

[0062] As another example, the enclosure 1 can be made of materials such as acrylonitrile butadiene styrene (ABS) or polypropylene (PP). These materials have high strength, good corrosion resistance, and good antibacterial properties.

[0063] Of course, those skilled in the art will understand that in some other embodiments, the housing 1 may also be made of an opaque material or any other suitable material. This application does not specifically limit the materials used to make the housing 1.

[0064] An opening 1a is formed at one end of the housing 1 along a first direction. The opening 1a connects to the sewage tank 100. A portion of the cover 2 has a shape consistent with the shape of the opening 1a, allowing it to be fitted over the opening 1a. Exemplarily, a seal may be provided at the opening 1a. When the cover 2 is fitted over the opening 1a, the seal seals the connection between the cover 2 and the housing 1, thereby reducing the possibility of fluid leakage from the sewage tank 100 through the opening 1a. The first direction may be the extending direction of the housing 1, such as... Figure 1 The direction of X in the equation.

[0065] For example, the tank body 1 may include a first locking element. The cover 2 may include a second locking element. The cover 2 and the tank body 1 can be locked together by the cooperation of the first and second locking elements. This reduces the possibility of the sewage tank 100 being accidentally opened during operation or transportation. The locking connection includes, but is not limited to, snap-fit, magnetic attraction, etc.

[0066] like Figure 2 and Figure 3 As shown, the cover 2 may include a cover body 21 and a support member 22. Along a first direction, the support member 22 is connected to the side of the cover body 21 facing the receiving cavity 10. When the cover 2 is positioned over the opening 1a, the cover body 21 closes the opening 1a, and the support member 22 is located within the receiving cavity 10. The support member 22 can provide stable support for structural components of the sewage tank 100 that need to be housed within the receiving cavity 10.

[0067] For example, the support member 22 can be integrally formed with the cover body 21 as a single structural component. This helps to reduce the number of parts and simplify assembly.

[0068] As another example, the support member 22 can be a separate structure from the cover body 21, and then assembled together. For example, it can be assembled by means of snap-fit, threaded connection, riveting, or adhesive.

[0069] An air vent 23 is formed on the side of the cover body 21 facing away from the receiving cavity 10. The air vent 23 is connected to the air inlet of the fan located on the main body. Under the action of the fan, a certain negative pressure zone is formed inside the main body. Sewage mixed with air flows towards the sewage tank 100 through the suction port. When the mixture enters the tank 1 at high speed, it will collide with some baffles, volutes or specially designed air passages inside the tank 1, thereby reducing the flow rate. Due to the action of gravity and centrifugal force, the heavier sewage or some solid waste will sink into the receiving cavity 10 of the sewage tank 100, while the lighter gas will separate out and continue to flow towards the fan through the air vent 23, and finally be discharged outside the main body by the fan.

[0070] In some embodiments, the wastewater tank 100 includes a first filter element 24. The first filter element 24 is located within the receiving cavity 10 and connected to the support member 22. Specifically, the first filter element 24 may be located on the wastewater recycling path. The airflow entering the receiving cavity 10 first passes through the first filter element 24, then reaches the air vent 23 at the top of the wastewater tank 100, and then enters the blower. Thus, the first filter element 24 can intercept larger water vapor, solid particles, or some fine dust in the air, reducing the possibility of water vapor and dirt flowing to the blower through the air vent 23 and causing damage to the blower.

[0071] In some embodiments, a second filter element may also be provided at the air outlet 23. This further reduces impurities carried by the recovered airflow, thereby further reducing the possibility of fan damage.

[0072] For example, the first filter element 24 and the second filter element include, but are not limited to, a filter screen, a sponge, or a HEPA filter. The first filter element 24 and the second filter element may be of the same type or different types.

[0073] In some embodiments, such as Figure 2 and Figure 3 As shown, the wastewater tank 100 also includes a water level detection device 4, which can be connected to the side of the cover 2 facing the receiving cavity 10. Specifically, the water level detection device can be connected to the support member 22 of the cover 2. Thus, the water level in the receiving cavity 10 of the wastewater tank 100 can be detected by the water level detection device 4. When the water level is high, the controller 200 can receive the signal from the water level detection device 4 in a timely manner and issue a reminder signal to remind the user to empty the wastewater. The reminder signal includes, but is not limited to, a visual reminder signal with flashing indicator lights, an audible reminder signal with sound alarms, or an alarm abnormality prompt popping up on a host computer (e.g., a mobile terminal).

[0074] For example, the water level detection device 4 can be a water level detection electrode.

[0075] After emptying wastewater, users need to clean the wastewater tank 100 promptly to reduce the possibility of dirt adhering to the inner wall of the tank 1, which could lead to bacterial growth or unpleasant odors. To fit the main body of the cleaning equipment and hold a certain amount of wastewater, the wastewater tank 100 is typically designed with a narrow shape. This means that during cleaning, users need to reach their arms into the tank's cavity 10 or use specialized cleaning tools, making the process inconvenient. Furthermore, cleaning the wastewater tank 100 may pollute the surrounding environment or soil clothing, negatively impacting the user experience.

[0076] In this embodiment, the wastewater tank 100 further includes a movable component 3. When the cover 2 is closed at the opening 1a, the movable component 3 is located within the receiving cavity 10. The movable component 3 includes a movable body 31 and a cleaning component 32. The movable body 31 is located on the side of the cover 2 facing the receiving cavity 10 and is movably connected to the cover 2. The movable body 31 is capable of reciprocating along a first direction in a direction away from or towards the cover 2. The first direction includes the extending direction of the tank 1.

[0077] In some embodiments, the movable body 31 can be movably connected to the cover 2 in any suitable manner, specifically, to the support member 22 of the cover 2. For example, a sliding connection, a rotating connection, etc. Those skilled in the art should understand that any connection method that enables the movable body 31 to reciprocate along the first direction in a direction away from or towards the cover body 21 is within the scope of protection of this application.

[0078] The cleaning component 32 is connected to the outer edge of the movable body 31. The cleaning component 32 is in contact with the inner wall of the housing 1.

[0079] Therefore, when the main body 31 reciprocates along the first direction, it drives the cleaning component 32 connected to the outer edge of the main body 31 to reciprocate along the first direction, thereby enabling the cleaning component 32 to scrape the inner wall of the sewage tank 100 back and forth along the first direction, cleaning the sewage tank 100. This cleaning method does not require the user to put their arm into the sewage tank 100 or use special cleaning tools to clean the inner wall, and it is less likely to pollute the surrounding environment or soil the user's clothes. The operation is simpler and more convenient, the cleaning effect is better, and it also helps to improve the user experience.

[0080] The cleaning component 32 is a structural component used for cleaning the inner wall of the housing 1. In some embodiments of this application, the cleaning component 32 includes any one of an elastic strip, a sponge, a non-woven fabric, a brush, or a porous mesh cleaning body. This application does not specifically limit the type of cleaning component 32; it can be replaced according to actual needs.

[0081] For example, the cleaning component 32 is detachably attached to the outer edge of the movable body 31. This can be achieved through snap-fit, plug-in, adhesive, or tight fit. The detachable mounting method makes it easier for the user to replace the cleaning component 32 later.

[0082] In some embodiments, the number of cleaning components 32 can be multiple. Multiple cleaning components 32 are spaced apart and connected to the outer edge of the active body 31 along a first direction. The multiple cleaning components 32 can be of the same type or different types.

[0083] In some embodiments, the number of cleaning components 32 can be multiple. The multiple cleaning components 32 are spaced apart along the circumferential direction of the outer edge of the active body 31.

[0084] This application does not specifically limit the quantity, type, or connection position of the cleaning components 32. Any solution that can contact the inner wall of the housing 1 and clean the inner wall is within the protection scope of this application.

[0085] In some embodiments of this application, such as Figure 2 As shown, the active body 31 includes a cleaning part 311 and a connecting part 312. The connecting part 312 is movably connected to the cover 2. The cleaning part 311 is located at the end of the connecting part 312 away from the cover 2.

[0086] The connecting part 312 is used to connect the cleaning part 311 and the cover 2. Specifically, the connecting part 312 is movably connected to the support member 22 of the cover 2, and the cleaning part 311 can reciprocate along with the reciprocating motion of the connecting part 312 relative to the support member 22 in the first direction, so that the cleaning member 32 can clean the inner wall of the box 1.

[0087] For example, there may be two connecting portions 312, which are spaced apart along the second direction and connected to opposite sides of the cleaning portion 311 along the second direction. The second direction intersects the first direction.

[0088] As another example, the shape of the connecting part 312 may be one or more (two or more).

[0089] In some embodiments, the connecting portion 312 and the cleaning portion 311 can be formed as a single, integral structural component. This integral structural component increases the strength and durability of the entire movable body 31 and reduces the number of parts, thus simplifying assembly.

[0090] In some embodiments, the connecting part 312 and the cleaning part 311 can also be separate structures that are then assembled together. This makes it easier for the user to clean or replace the cleaning part 311 later.

[0091] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, a filter hole 6 is provided at the end of the movable body 31 away from the cover 2, that is, the cleaning part 311 can be provided with a filter hole 6. In this way, when the sewage tank 100 is full, the user can remove the sewage tank 100 from the main body of the cleaning equipment and remove the cover 2 from the opening 1a to prepare to pour out the sewage. The movable body 31 can be used to filter the sewage. This allows the sewage to pass through the filter hole 6 before being poured out, thereby filtering out most of the impurities in the sewage and reducing the possibility of large impurities being directly poured into the drainage position (such as the toilet, sewer, etc.) and causing blockage of the drainage position.

[0092] In this embodiment, the filter hole 6 is generally elongated. In some other embodiments, the filter hole 6 may also be circular, square, or any other suitable shape. This embodiment does not specifically limit the shape of the filter hole 6.

[0093] In some embodiments, the cleaning section 311 may have a plurality of filter holes 6. The plurality of filter holes 6 may have the same shape or different shapes. The plurality of filter holes 6 may have the same diameter or different diameters.

[0094] like Figure 3 As shown, the cleaning section 311 may include, for example, a first segment 3111 and a second segment 3112. The first segment 3111 extends generally along a first direction. The second segment 3112 extends generally along a second direction intersecting the first direction and generally extends to the inner wall of the housing 1. Thus, when emptying wastewater, the user can open the cover 2 without completely removing the movable part 3 from the receiving cavity 10, allowing the wastewater to flow through the filter holes 6 of the first segment 3111 and the second segment 3112 before being poured out of the wastewater tank 100, thereby achieving wastewater filtration. Alternatively, the user can completely remove the movable part 3 from the receiving cavity 10 and place the cleaning section 311 horizontally at the opening 1a before emptying the wastewater, thereby achieving wastewater filtration.

[0095] The cleaning component 32 may be provided in the first section 3111 of the cleaning unit 311, or in the second section 3112, or both in the first section 3111 and the second section 3112.

[0096] Those skilled in the art will understand that the second direction intersects the first direction. In some embodiments, the second direction may be perpendicular to the first direction. However, the embodiments of this application are not limited to the case where the second direction is perpendicular to the first direction. That is, the second segment 3112 may extend generally in a direction parallel to the horizontal plane, or it may extend in a direction inclined relative to the horizontal plane.

[0097] like Figure 2As shown, the cleaning section 311 has an extension 311a extending in a second direction. The cleaning member 32 is provided at the outer edge of the extension 311a. This allows the cleaning member 32 to better contact the inner wall of the housing 1 and increases the contact area with the inner wall, thereby improving the cleaning effect of the cleaning member 32.

[0098] Normally, the movable body 31 does not occupy the entire cross-sectional space of the box 1; that is, there may be some positions where it cannot contact the inner wall of the box 1 or is far from the inner wall of the box 1. If the cleaning component 32 is directly disposed on the outer edge of the movable body 31 along the entire circumference of the inner wall of the box 1, the contact area between the cleaning component 32 and the inner wall may be limited. Therefore, in this embodiment, by providing an extension 311a in the cleaning part 311, the cleaning component 32 can better contact the inner wall of the box 1, thereby improving the cleaning effect.

[0099] The extension 311a can extend generally parallel to the horizontal plane, or it can extend in a direction inclined relative to the horizontal plane. This application does not specifically limit the second direction of the extension 311a's extension. Any solution that allows the extension direction of the extension 311a to intersect the first direction and contact the inner wall of the housing 1 is within the scope of protection of this application.

[0100] In some embodiments of this application, the outer edge contour shape of the extension 311a is adapted to at least a portion of the contour shape of the inner wall of the housing 1.

[0101] Therefore, it can better fit the inner wall of the box 1, so that the cleaning component 32 can make close contact with the inner wall of the box 1, reduce cleaning dead corners, and improve the cleaning effect of the cleaning component 32.

[0102] In this embodiment, the extension 311a is generally semi-circular in shape, and its outer edge contour is arc-shaped. In some other embodiments, the extension 311a may also be formed into any other suitable shape, such as a circle or a polygon. The outer contour shape of the extension 311a may be linear, wavy, or any other suitable shape. This embodiment does not specifically limit the shape of the extension 311a or the shape of its outer contour; specific settings can be made according to the contour shape of the inner wall of the actual housing 1.

[0103] The number of extensions 311a can be multiple, and the multiple extensions 311a can be spaced apart from each other along the first direction. The shapes of the various extensions 311a can be the same or different. In the same projection plane perpendicular to the first direction, the multiple extensions 311a can at least partially overlap or be completely staggered. As a result, the contact area between the cleaning component 32 and the inner wall of the housing 1 is larger and the contact range is wider, thereby reducing cleaning dead corners, better cleaning the inner wall of the housing 1, and improving the cleaning effect.

[0104] In some embodiments, filter holes 6 may also be formed on the extension 311a.

[0105] In some embodiments, the active body 31 may be provided with some components with other functions, which may also extend along the second direction. In this case, these components can also serve as extensions 311a. The cleaning component 32 can be disposed on the outer edge of these components, so as to better contact the inner wall of the housing 1.

[0106] For example, the second segment 3112 of the cleaning section 311 mentioned above can also serve as an extension 311a.

[0107] Of course, those skilled in the art will understand that in some embodiments, the cleaning part 311 may not include the extension 311a. The cleaning member 32 may be directly connected to the outer edge of the cleaning part 311.

[0108] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the wastewater tank 100 also includes a drive assembly 5. The drive assembly 5 is connected to the cover 2. The drive assembly 5 includes an output section. The movable body 31 is connected to the output section.

[0109] The drive assembly 5 is a structural component that provides power to the movable body 31. The output section is used to output the power of the drive assembly 5. The movable body 31 is connected to the output section of the drive assembly 5 and can reciprocate in a first direction under the drive of the drive assembly 5, thereby driving the cleaning component 32 to reciprocate in the first direction, and thus cleaning the inner wall of the housing 1. Specifically, the drive assembly 5 can be connected to the support member 22 of the cover 2.

[0110] For example, the drive assembly 5 may include a motor, a rotary cylinder, or other drive assembly 5 that outputs rotational power, or an electric telescopic cylinder, a pneumatic / hydraulic telescopic cylinder, or other drive assembly 5 that outputs linear power. As a specific example, the drive assembly 5 may include a motor. Motors have high precision and fast response speed.

[0111] Those skilled in the art will understand that the embodiments of this application do not specifically limit the type of the driving component 5.

[0112] The reciprocating motion of the main body 31 along the first direction is achieved by using the drive component 5, which has a higher degree of automation and better flexibility.

[0113] For example, the user can input control commands in the host computer to control the timed movement of the drive component 5, so that the active body 31 can clean the inner wall of the box 1 at regular intervals.

[0114] As another example, a dirt detection sensor may be installed in the wastewater tank 100. When the dirt detection sensor detects that the dirt exceeds a certain threshold, it sends a cleaning command to the controller 200. The controller 200 controls the drive component 5 to move based on the cleaning command, thereby causing the moving body 31 to reciprocate, thereby cleaning the inner wall of the tank 1.

[0115] In this way, even if the user does not use the cleaning equipment frequently, or forgets to clean the wastewater tank 100, the active body 31 can still automatically clean the tank 1, further reducing the possibility of bacteria growth or odor in the containment cavity 10 and improving the user experience.

[0116] Of course, those skilled in the art should understand that in some embodiments, the sewage tank 100 may not be equipped with a drive component 5, and the user may manually make the moving body 31 reciprocate along the first direction.

[0117] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the drive assembly 5 is located inside the receiving cavity 10 and is connected to the side of the cover 2 facing the receiving cavity 10. Specifically, it is connected to the support member 22 of the cover 2. The support member 22 can provide an installation and fixing position for the drive assembly 5, thereby eliminating the need for additional support structures. This helps to reduce the number of parts in the sewage tank 100, reduce assembly difficulty, and also helps to improve the integration and lightweighting of the sewage tank 100.

[0118] In addition, placing the drive component 5 inside the receiving cavity 10 helps to shorten the power transmission path (for example, eliminating the need for a long drive shaft), thereby reducing energy loss in intermediate links and making power transmission more uniform and efficient.

[0119] For example, the wastewater tank 100 also includes a protective element. The protective element covers the outside of the drive assembly 5.

[0120] Therefore, the protective component isolates the drive assembly 5 from the sewage and dirty physical environment inside the housing 1, thereby reducing the risk of sewage intrusion into the drive assembly 5, which could cause short circuits or burnout of the electrical components inside the drive assembly 5. Furthermore, covering the drive assembly 5 with the protective component also reduces the likelihood of dirt, hair, and other contaminants in the sewage being drawn into the drive assembly 5, thus reducing the possibility of jamming or abnormal wear. The protective component ensures the long-term, stable, and reliable operation of the drive assembly 5, extending its service life. This allows the moving body 31 to move stably and continuously, enabling the cleaning component 32 to effectively clean the inner wall of the housing 1 for an extended period.

[0121] In addition, the protective components can also prevent users from accidentally touching the drive component 5 when emptying sewage, replacing parts, or cleaning the housing 1, which helps to improve user safety and enhance the user experience.

[0122] In some embodiments, the protective component is generally a hollow box or cabin structure, and its outline matches the outline of the drive assembly 5. The protective component has an internal receiving space for accommodating the drive assembly 5. A through-hole is provided on the protective component. The through-hole allows the output portion of the drive assembly 5 to pass through, thereby enabling the output portion to be directly or indirectly connected to the movable body 31.

[0123] For example, a seal is provided at the through hole. When the output part passes through the through hole, the seal is located between the outer periphery of the output part and the inner periphery of the through hole. The seal can provide a good seal, reducing the possibility of sewage, dirt, etc. in the housing 1 entering the receiving space through the through hole, and further reducing the possibility of damage to the drive assembly 5.

[0124] The sealing components include, but are not limited to, rotary oil seals. The inner lip of the oil seal can be interference-fitted with the output part of the drive assembly 5, and can rotate together with the output part to achieve dynamic sealing. Thus, a good seal of the protective component can be achieved without affecting the operation of the drive assembly 5.

[0125] For example, the protective component can be made of materials such as ABS and PP. These materials have high strength, are lightweight, and also have good insulation and corrosion resistance. Of course, the embodiments of this application do not specifically limit the material of the protective component.

[0126] In some embodiments, the protective component may include two separate housings. The two housings are respectively positioned on opposite sides of the drive assembly 5. The two housings can be connected together by threaded connections, plug-in connections, snap-fit ​​connections, adhesive connections, or riveting. This separate housing structure facilitates assembly.

[0127] Of course, in some other embodiments, the protective component may also be a one-piece molded structural component.

[0128] In some embodiments, such as Figure 2 As shown, the drive assembly 5 is connected to one side of the support member 22 of the cover 2 along the second direction. In this case, the protective member can be formed as a cylindrical shape with an opening. The protective member is integrally fastened to the outer periphery of the cover, and the outer edge of the opening of the protective member abuts against the support member 22. Exemplarily, the protective member can be connected to the support member 22 of the cover 2 by means of adhesive bonding, threaded connection, snap-fit, riveting, etc., thereby providing good protection and isolation for the drive assembly 5.

[0129] For example, a seal may be provided at the opening of the protective member. The seal is sealingly connected between the opening and the support member 22. The seal includes, but is not limited to, sealing rings, sealing gaskets, oil seals, etc.

[0130] In some embodiments, the drive assembly 5 is connected to the movable body 31 via the transmission assembly 7, and both the drive assembly 5 and the transmission assembly 7 are located within the housing 1. The protective component can be completely covered on the outside of both the drive assembly 5 and the transmission assembly 7, thereby providing good protection for both simultaneously.

[0131] In some embodiments, when a portion of the drive assembly 5 or a portion of the transmission assembly 7 is located inside the housing 1, a protective element may be provided over the outside of the portion of the drive assembly 5 or transmission assembly 7 located inside the housing 1.

[0132] In some embodiments, the inner wall of the protective component may be provided with reinforcing ribs to increase the structural strength of the protective component and reduce the possibility of resonance noise generated by the drive assembly 5 due to vibration during operation.

[0133] In some embodiments, heat dissipation fins may be provided on the outer wall of the protective component. This allows the heat generated by the drive assembly 5 to be quickly conducted to the outside via the heat dissipation fins, reducing performance loss caused by excessively high temperatures in the drive assembly 5.

[0134] Of course, those skilled in the art will understand that in some other embodiments, at least a portion of the drive component 5 may be disposed outside the receiving cavity 10.

[0135] For example, the drive assembly 5 may be completely disposed outside the receiving cavity 10 and connected to the side of the cover body 21 opposite to the receiving cavity 10. The sewage tank 100 may also include a transmission assembly 7, a portion of which extends beyond the receiving cavity 10, and the output portion of the drive assembly 5 is connected to the transmission assembly 7.

[0136] As another example, the drive assembly 5 may be partially disposed outside the receiving cavity 10. For instance, the main body of the drive assembly 5 may be disposed outside the receiving cavity 10 and connected to the side of the cover body 21 opposite to the receiving cavity 10. The output portion extends into the interior of the receiving cavity 10 and is connected to the movable body 31.

[0137] Therefore, the drive component 5 can be physically isolated from the sewage in the sewage tank 100, reducing the possibility of damage to the drive component 5.

[0138] In some embodiments of this application, such as Figures 3 to 7 As shown, the wastewater tank 100 also includes a transmission assembly 7. The transmission assembly 7 is at least partially located within the receiving cavity 10. The transmission assembly 7 connects the output section and the movable body 31.

[0139] The transmission assembly 7 is a mechanism for transmitting power from the drive assembly 5 to the movable body 31. The transmission assembly 7 can change the output torque of the drive assembly 5 to meet the motion requirements of the movable body 31. Alternatively, the transmission assembly 7 can change the motion form of the drive assembly 5 to meet the motion requirements of the movable body 31. For example, the transmission assembly 7 can convert the rotational power output by the drive assembly 5 into linear power.

[0140] The transmission assembly 7 includes, but is not limited to, the gear and rack transmission assembly 7, the worm gear transmission assembly 7, and the pulley transmission assembly 7.

[0141] For example, the transmission assembly 7 is connected to the connecting portion 312 of the movable body 31. When there are multiple connecting portions 312 (two or more), the transmission assembly 7 may be connected to one of the connecting portions 312. Alternatively, there may be multiple transmission assemblies 7, with each of the multiple transmission assemblies 7 connected to a multiple of the connecting portions 312.

[0142] In some embodiments of this application, such as Figure 4 As shown, the transmission assembly 7 includes a first gear 71 and a first rack 72. The first gear 71 meshes with the first rack 72. The first rack 72 is distributed along a first direction. The first gear 71 is connected to the output section. The first rack 72 is connected to the movable body 31.

[0143] Specifically, the first rack 72 is connected to the connecting part 312 of the movable body 31 and is distributed along the first direction.

[0144] For example, along the first direction, the first rack 72 extends from the end of the connecting portion 312 away from the cleaning portion 311 toward the cleaning portion 311. The length of the first rack 72 along the first direction can be the same as the length of the connecting portion 312, or it can be less than the length of the connecting portion 312. Thus, the first rack 72 is completely connected to the connecting portion 312, which helps to improve the connection reliability of the first rack 72.

[0145] As another example, along the first direction, the first rack 72 is connected to the end of the connecting portion 312 away from the cleaning portion 311, and extends at least partially beyond the connecting portion 312 in the direction away from the cleaning portion 311. This reduces the length of the connecting portion 312 along the first direction, thus lowering manufacturing costs. Furthermore, when the connecting portion 312 reciprocates along the first direction under the drive of the first rack 72, it is less likely to interfere with the cover body 21, improving the reliability of the movable body 31.

[0146] This application embodiment does not specifically limit the length of the first rack 72, but can set it according to the stroke required for the actual moving body 31.

[0147] The first gear 71 is disposed on the side of the cover 2 facing the receiving cavity 10 and meshes with the first rack 72. The output part of the drive assembly 5 is connected to the first gear 71 and is used to drive the first gear 71 to rotate. The first rack 72 can move along the first direction as the first gear 71 rotates, thereby driving the connecting part 312 of the movable body 31 to move along the first direction. When it is necessary to change the direction of movement, the rotation direction of the first gear 71 is changed by the drive assembly 5, that is, the movement direction of the first rack 72 along the first direction can be changed, thereby realizing the reciprocating movement of the connecting part 312 along the first direction, so that the cleaning part 32 can reciprocate along the first direction to scrape the inner wall of the box 1, thereby cleaning the inner wall of the box 1 and achieving a better cleaning effect.

[0148] The gear and rack transmission assembly 7 has high mechanical efficiency, low power loss, and lower energy consumption. As a result, the drive assembly 5 has a smaller load, is less prone to overheating, and has a longer service life.

[0149] Moreover, the rack and pinion drive assembly has a strong load-bearing capacity. Even if the frictional resistance between the cleaning component 32 and the inner wall of the housing 1 is large (for example, there is stubborn dirt), the rack and pinion drive assembly can provide enough force to overcome the resistance, ensuring the smooth progress of the cleaning work and preventing jamming or slippage.

[0150] In addition, the gear and rack transmission assembly has a compact structure and will not occupy too much space in the housing cavity 10, which is conducive to the integration and lightweighting of the sewage tank 100.

[0151] In some embodiments of this application, such as Figure 5 As shown, the transmission assembly 7 includes a first worm gear 73, a first worm 74, and a second rack 75. The first worm 74 is connected to the output section. The first worm gear 73 is located between the first worm 74 and the second rack 75, and meshes with both the first worm 74 and the second rack 75. The second rack 75 is distributed along a first direction. The second rack 75 is connected to the movable body 31.

[0152] Specifically, the second rack 75 is connected to the connecting portion 312 of the movable body 31. Exemplarily, along the first direction, the second rack 75 extends from the end of the connecting portion 312 away from the cleaning portion 311 toward the cleaning portion 311. Also exemplaryly, along the first direction, the second rack 75 is connected to the end of the connecting portion 312 away from the cleaning portion 311, and at least partially extends beyond the connecting portion 312 in the direction away from the cleaning portion 311.

[0153] This application embodiment does not specifically limit the length of the second rack 75, but can set it according to the stroke required for the actual moving body 31.

[0154] The first worm gear 74 is disposed on the side of the cover 2 facing the receiving cavity 10. The output part of the drive assembly 5 is connected to the first worm gear 74 and is used to drive the first worm gear 74 to rotate around a first direction. The first worm wheel 73 meshes with the first worm gear 74 and can rotate together with the rotation of the first worm gear 74. The rotation axis of the first worm wheel 73 is substantially perpendicular to the rotation axis of the first worm gear 74. The second rack 75 meshes with the first worm wheel 73 and can move along the first direction with the rotation of the first worm wheel 73, thereby driving the connecting part 312 to move along the first direction. When it is necessary to change the direction of movement, the rotation direction of the first worm gear 74 is changed by the drive assembly 5, thereby changing the rotation direction of the first worm wheel 73, and thus changing the direction of movement of the second rack 75 along the first direction, realizing the reciprocating motion of the connecting part 312 along the first direction.

[0155] Worm gear transmission assemblies have the characteristic of a large reduction ratio. The first worm 74 rotates many times for the first worm wheel 73 to rotate only once. Therefore, worm gear transmission assemblies can use drive components 5 with lower power and higher speeds, and output low-speed, high-torque motion through the worm gear transmission assembly, which helps reduce system cost and energy consumption.

[0156] Furthermore, the worm gear has a certain directional self-locking performance. When the lead angle of the first worm 74 is small, only the first worm 74 can actively drive the first worm wheel 73 to rotate, while the first worm wheel 73 cannot drive the first worm 74 to rotate in any direction. Therefore, when the drive assembly 5 stops working, the movable body 31 will be locked in its current position, making it less likely to move or slip due to gravity, sewage sloshing, or external forces, thus ensuring the safety and stability of the movable body 31. In the event of an unexpected power outage, the movable body 31 is also less likely to fall uncontrollably, thereby improving the reliability of the sewage tank 100.

[0157] Furthermore, since the rotation axes of the first worm gear 73 and the first worm 74 intersect, the layout of the first worm gear 73 and the first worm 74 is more flexible, which optimizes the space utilization within the receiving cavity 10 and makes the overall structure of the sewage tank 100 more compact.

[0158] In some embodiments of this application, such as Figure 6 As shown, the transmission assembly 7 includes a rotating wheel 76 and a cable 77. The rotating wheel 76 is connected to the output unit. One end of the cable 77 is connected to the rotating wheel 76, and the other end of the cable 77 is connected to the movable body 31.

[0159] The rotating wheel 76 is connected to the side of the cover 2 facing the receiving cavity 10. Specifically, the rotating wheel 76 is rotatably connected to the support member 22 of the cover 2 and is located on the side of the support member 22 near the opening 1a along the first direction.

[0160] The output of the drive assembly 5 is connected to the rotating wheel 76 to drive the rotating wheel 76 to rotate. One end of the cable 77 is connected to the rotating wheel 76, and the other end is connected to the connecting part 312 of the movable body 31. The cable 77 can be wound up or unwound under the rotation of the rotating wheel 76. When the cable 77 is wound up under the rotation of the rotating wheel 76, the connecting part 312 moves towards the cover 2 in a first direction. When the cable 77 is unwound under the rotation of the rotating wheel 76, the connecting part 312 moves away from the cover 2 in the first direction. Thus, the movable body 31 can reciprocate in the first direction with the cooperation of the rotating wheel 76 and the cable 77, thereby causing the cleaning component 32 to scrape the inner wall of the box 1 and clean the box 1.

[0161] In some embodiments, the wheel 76 is generally cylindrical, and the circumferential surface of the wheel 76 is used to support the cable 77. The cable 77 may, for example, be generally wound into a ring and fitted onto the circumferential surface of the wheel 76. The wheel 76 can rotate along the axis of rotation under the drive of the drive assembly 5, thereby winding or unwinding the cable 77 wound on its circumferential surface.

[0162] Of course, those skilled in the art will understand that in some other embodiments, the wheel 76 may also be prismatic or any other suitable shape. This application does not specifically limit the shape of the wheel 76; any solution capable of winding and unwinding the cable 77 is within the scope of protection of this application.

[0163] For example, the cable 77 may include a steel wire rope, nylon rope, timing belt, etc. This application embodiment does not specifically limit the material of the cable 77, as long as it can stably pull the connecting part 312 of the movable body 31.

[0164] In some embodiments, the transmission assembly 7 may not include the pulley 76. One end of the cable 77 may be directly wound around the output of the drive assembly 5, and under the drive of the drive assembly 5, it may be wound or unwound on the output, thereby driving the movable body 31 to reciprocate along the first direction.

[0165] Since the cable 77 is typically flexible, this flexible transmission method results in quieter operation, improving the user experience. The structure of the rotor 76 and cable 77 is also relatively simple, helping to reduce the overall manufacturing cost and assembly complexity of the sewage tank 100.

[0166] Moreover, the layout of the transmission assembly 7 of the wheel 76 and the cable 77 is very flexible, which makes the setting position of the drive assembly 5 more flexible, greatly optimizing the space utilization and design freedom inside the housing 1.

[0167] Furthermore, by selecting a sufficiently long cable 77, the long stroke movement of the moving body 31 can be achieved. Moreover, the cable 77 is wound around the circumference of the rotating wheel 76. Therefore, while achieving a long stroke, it does not occupy excessive space, which helps to further improve the space utilization rate within the housing 1.

[0168] In some embodiments of this application, the drive assembly 5 is disposed on the portion of the cover 2 located outside the receiving cavity 10. The cover 2 has a through hole for the cable 77 to pass through.

[0169] Therefore, the drive assembly 5 can be located outside the receiving cavity 10, thereby achieving dry and wet separation between the drive assembly 5 and the housing 1, reducing the possibility of drive assembly 5 malfunctioning due to water vapor erosion, dirt adhesion, hair entanglement, etc., and improving the service life of drive assembly 5.

[0170] The rotating wheel 76 is also located on the portion of the cover 2 outside the receiving cavity 10 and is connected to the output shaft of the drive assembly 5. This reduces the space occupied by the transmission assembly 7 within the housing 1 and also reduces the possibility of damage to the rotating wheel 76.

[0171] In some embodiments of this application, such as Figure 7 As shown, the transmission assembly 7 includes a second worm 78, a second worm wheel 79, a first fixed pulley 80, a second fixed pulley 81, and a rope 82. The second worm 78 is connected to the output part. The second worm wheel 79 meshes with the second worm 78. The first fixed pulley 80 and the second fixed pulley 81 are spaced apart along a first direction. The first fixed pulley 80 is fixedly connected to the second worm wheel 79. The second fixed pulley 81 is rotatably connected to the cover 2. The rope 82 is wound around the circumference of the first fixed pulley 80 and the second fixed pulley 81, and both ends of the rope 82 are connected to the movable body 31.

[0172] The second worm gear 78 is disposed on the side of the cover 2 facing the receiving cavity 10. The output part of the drive assembly 5 is connected to the second worm gear 78 and is used to drive the second worm gear 78 to rotate about a first direction. The second worm wheel 79 meshes with the second worm gear 78 and can rotate together with the rotation of the second worm gear 78. The rotation axis of the second worm wheel 79 is substantially perpendicular to the rotation axis of the second worm gear 78.

[0173] The first fixed pulley 80 is fixedly connected to the second worm gear 79. The first fixed pulley 80 can rotate together with the rotation of the second worm gear 79. Specifically, the first fixed pulley 80 can be arranged coaxially with the second worm gear 79. The second fixed pulley 81 is spaced apart from the first fixed pulley 80 along a first direction and is connected to the support member 22 of the cover 2 on the side away from the opening 1a along the first direction. In this embodiment, the distance between the first fixed pulley 80 and the second fixed pulley 81 along the first direction is not specifically limited, but can be specifically limited according to the stroke required for the actual moving body 31.

[0174] Rope 82 is wound around the circumference of the first fixed pulley 80 and the second fixed pulley 81, and both ends of rope 82 are connected to the connecting part 312 of the movable body 31. Thus, the second worm gear 78 can rotate under the drive of the drive assembly 5, thereby driving the second worm wheel 79, which meshes with the second worm gear 78, to rotate, and in turn driving the first fixed pulley 80, which is fixedly connected to the second worm wheel 79, to rotate. At this time, the first fixed pulley 80 will wind one side of rope 82 and release the other side of rope 82. Simultaneously, the second fixed pulley 81 will also release one side of rope 82 and wind the other side of rope 82. Since both ends of rope 82 are connected to the connecting part 312, a pulling force can be generated to pull the movable body 31.

[0175] The two fixed pulleys ensure that the rope 82 always pulls the movable body 31 at a preset angle, that is, the direction of the pulling force is consistent with the preset first direction. In addition, the two fixed pulleys ensure that the rope 82 is always taut, reducing the possibility of rope slippage and ensuring that the transmission component 7 transmits power efficiently and accurately.

[0176] This application does not specifically limit the material of the rope 82.

[0177] For example, the first fixed pulley 80 and the second fixed pulley 81 have the same diameter. Therefore, when the second worm gear 79 rotates, the first fixed pulley 80 and the second fixed pulley 81 can rotate at the same speed, thereby uniformly pulling the movable body 31 to reciprocate along the first direction, making the movement of the movable body 31 more stable and reliable, and improving the cleaning effect.

[0178] In some other embodiments, the diameters of the first fixed pulley 80 and the second fixed pulley 81 may also be different.

[0179] The worm gear has a certain directional self-locking performance. When the drive component 5 stops working, the moving body 31 will be locked in the current position, and it is not easy for it to move or slide on its own due to gravity, sewage shaking or external forces, thus ensuring the safety and stability of the moving body 31.

[0180] Of course, those skilled in the art will understand that in some embodiments, the transmission assembly 7 may not include the second worm gear 79 and the second worm 78. The output of the drive assembly 5 may be directly connected to the first fixed pulley 80 or the second fixed pulley 81 to drive the first fixed pulley 80 or the second fixed pulley 81 to move.

[0181] In some embodiments of this application, the wastewater tank 100 further includes a controller 200 (not shown in the figure) and a position detection component (not shown in the figure). The position detection component is disposed on the movable body 31 or on the cover 2. The position detection component is used to detect the distance between the movable body 31 and the cover 2. Both the position detection component and the drive component 5 are communicatively connected to the controller 200. Based on the distance detected by the position detection component, the controller 200 controls the movement direction of the drive component 5 to achieve reciprocating motion of the movable component 3 along a first direction.

[0182] The position detection component is communicatively connected to the controller 200 and the drive component 5. It can transmit the distance between the moving body 31 and the cover 2 detected by the position detection component, specifically the distance between the moving body 31 and the cover body 21, to the controller 200 in a timely manner. This allows the controller 200 to control the rotation direction of the drive component 5 to achieve the reciprocating motion of the moving part 3 along the first direction.

[0183] In some embodiments, the controller 200 can preset the distances between the upper limit position and the cover 2 of the movable body 31 and the lower limit position of the movable body 31, that is, the two endpoint positions of the reciprocating motion of the movable body 31. The controller 200 compares the actual received interval distance with the preset values. When the controller 200 determines that the movable body 31 has moved to the upper limit position (i.e., the interval distance between the movable body 31 and the cover 2 is the minimum), the controller 200 can immediately issue a command to the drive component 5 to change its movement direction (e.g., from forward to reverse, or from contraction to extension). When the controller 200 determines that the movable body 31 has moved to the lower limit position (i.e., the interval distance between the movable body 31 and the cover 2 is the maximum), the controller 200 can issue another command to change the movement direction of the drive component 5 again (e.g., from reverse to forward, or from extension to contraction). Therefore, the sewage tank 100 can automatically control the movement direction of the drive component 5 through the position detection component and the controller 200, which has a higher degree of automation, better reliability, and can also reduce the possibility of interference between the moving part 3 and the cover body 21 and the bottom wall of the tank 1.

[0184] For example, the position detection component can be electrically connected to the controller 200 and the drive component 5, via Bluetooth, antenna signal connection, or WiFi connection, etc. This application does not specifically limit the connection method between the position detection component and the drive component 5; any connection method that enables information transmission is within the scope of protection of this application.

[0185] The position detection component can be disposed on the cover body 21 of the cover 2, or on the connecting part 312 of the movable body 31. This embodiment does not limit the specific location of the position detection component, as long as it can detect the distance between the cover 2 and the movable body 31.

[0186] For example, position detection sensors include, but are not limited to, infrared sensors, ultrasonic sensors, Hall effect sensors, or photoelectric encoders.

[0187] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the wastewater tank 100 also includes a guide assembly 9. The guide assembly 9 includes a first guide member 91 and a second guide member 92. The first guide member 91 is disposed on the cover 2. The second guide member 92 is disposed on the movable body 31. The first guide member 91 and the second guide member 92 are capable of sliding relative to each other along a first direction.

[0188] Specifically, the first guide member 91 is connected to the support member 22 of the cover 2. The second guide member 92 is connected to the connecting part 312 of the movable body 31. The number of guide components 9 can be one or more. When there are multiple guide components 9 and multiple connecting parts 312, each connecting part 312 can be provided with a second guide member 92, or multiple second guide members 92 can be provided on one connecting part 312.

[0189] Therefore, the wastewater tank 100 can constrain and guide the movement path of the moving body 31 through the guide component 9, ensuring that the moving body 31 can only move in a stable straight line along a preset first direction, reducing the possibility of the moving body 31 deflecting, swaying, or getting stuck. Because the moving body 31 is less prone to deflection, the cleaning component 32 can always maintain contact with the inner wall of the tank 1 at a preset angle and pressure, thus ensuring the cleaning effect of the cleaning component 32 during each reciprocating motion. This helps reduce the risk of some areas not being cleaned properly due to uneven pressure and improves the cleaning effect of the cleaning component 32.

[0190] Furthermore, the guide component 9 can provide stable support for the moving body 31, reduce friction during the movement of the moving body 31, and make the movement of the moving body 31 more stable, thereby reducing noise and vibration during the movement of the moving body 31, which in turn helps to improve the user experience.

[0191] Furthermore, with the guide assembly 9 installed in the sewage tank 100, a more stable rigid connection is formed between the movable body 31, the cover 2, and the tank 1, which helps to improve the structural strength of the entire mechanical system. When the sewage tank 100 is subjected to external forces (e.g., handling or collision), the movable part 3 is less likely to be damaged or displaced.

[0192] Of course, those skilled in the art will understand that in some other embodiments, the sewage tank 100 may not be provided with the guide assembly 9.

[0193] In some embodiments of this application, one of the first guide member 91 and the second guide member 92 includes a groove. The other includes a slider that mates with the groove. One of the groove and the slider is distributed along a first direction.

[0194] The first guide member 91 or the second guide member 92 can support, fix, and guide the moving parts or devices and reduce friction during their movement. The slide is generally groove-shaped, and the slider may have a protrusion. When the slide is distributed along a first direction, the protrusion of the slider extends into the groove of the slide, and the slider can move along the groove along the first direction. When the slider is distributed along the first direction, the slide is supported on the slider, and the slide can move along the slider along the first direction.

[0195] The main body 31 and the cover 2 can reciprocate in a stable and reliable manner along the first direction through the cooperation of the sliding groove and the slider.

[0196] For example, the first guide 91 includes a groove. The second guide 92 includes a slider.

[0197] As another example, the first guide 91 includes a slider. The second guide 92 includes a groove.

[0198] In some embodiments of this application, the wastewater tank 100 further includes a spray assembly. The spray assembly is located within the receiving cavity 10, and the spray nozzles of the spray assembly face the inner wall of the tank 1.

[0199] A spray assembly is a device for spraying liquids. For example, it can spray clean water or cleaning fluid onto the inner wall of the housing 1. The spray assembly may include multiple spray nozzles. These nozzles face different directions, thus enabling the spraying of liquid in different directions. Alternatively, the spray assembly may include only one spray nozzle. This nozzle may rotate about a first direction or a second direction, thereby spraying liquid in different directions.

[0200] In some embodiments, before the movable body 31 moves in the first direction, cleaning liquid can be sprayed onto the inner wall of the tank 1 by a spray assembly to soften some stubborn stains. Then, the reciprocating movement of the movable body 31 in the first direction causes the cleaning component 32 to scrape the inner wall of the tank 1. This helps to improve the cleaning effect on the wastewater tank 100.

[0201] In some embodiments, after the active body 31 reciprocates along the first direction, a cleaning liquid or water can be sprayed onto the inner wall of the tank 1 by the spray assembly to perform secondary cleaning of the inner wall of the tank 1, washing away the dirt scraped by the cleaning component 32, and further improving the cleaning effect on the sewage tank 100.

[0202] In some embodiments, liquid may be sprayed onto the inner wall of the housing 1 via a spray assembly both before and after the moving body 31 reciprocates along the first direction. Alternatively, liquid may be sprayed onto the inner wall of the housing 1 via a spray assembly while the moving body 31 is reciprocating along the first direction.

[0203] This application does not specifically limit the structure of the spray assembly. Any suitable commercially available spray assembly can be selected.

[0204] This application also provides a cleaning system. The cleaning system includes cleaning equipment and a base station. The base station is used to support the cleaning equipment.

[0205] A base station is a fixed or movable auxiliary device in a cleaning system. It is typically connected to a power source and directly or indirectly participates in the cleaning of the surface. After the cleaning equipment completes its work, it returns to the base station. The base station can perform operations such as charging, dust collection, washing, or drying of the cleaning equipment. When the cleaning equipment is not in use, the base station can also serve a storage function.

[0206] Base stations can integrate additional control buttons, displays, etc. They can also connect to home Wi-Fi (wireless compatibility certified), serving as the control hub for the entire cleaning system.

[0207] This application also provides a control method for a cleaning system. The cleaning system includes cleaning equipment. The cleaning equipment includes a wastewater tank 100. The wastewater tank 100 includes a tank body 1 and a movable component 3. The movable component 3 includes a movable main body 31 and a cleaning component 32. The cleaning component 32 is connected to the outer edge of the movable main body 31 and contacts the inner wall of the tank body 1.

[0208] like Figure 8 As shown, the control methods for the cleaning system include:

[0209] S100: In response to a cleaning command from the wastewater tank 100, controls the wastewater tank 100 to draw in a preset amount of cleaning liquid.

[0210] S200: Control the moving part 3 to reciprocate along the extension direction of the box 1 so that the cleaning part 32 scrapes the inner wall of the box 1.

[0211] For example, the cleaning command can be manually triggered by the user. For instance, the user can click the cleaning button on the operation panel of the cleaning equipment or base station or on the software of a mobile terminal to issue a cleaning command for the wastewater tank 100 to the controller 200.

[0212] As another example, the cleaning instruction can be initiated automatically after the device has completed some cleaning tasks. Alternatively, it can be initiated automatically periodically based on a built-in timer.

[0213] Therefore, users only need to issue a command, or even without issuing a command, for the device to automatically complete the entire process from injecting cleaning fluid to scraping and cleaning, achieving a high degree of automation. Users are essentially freed from the manual cleaning of the wastewater tank 100, significantly improving the user experience. Moreover, triggering the cleaning command for the wastewater tank 100 by setting a timer or after completing certain cleaning tasks reduces the likelihood of users forgetting to clean the tank 100, and reduces the possibility of dirt remaining on the inner wall of the tank 1 for extended periods. This effectively inhibits bacterial growth and odor generation, improving the hygiene of the equipment and enhancing the user experience.

[0214] In some embodiments of this application, the wastewater tank 100 also includes a spray assembly. For example... Figure 9 As shown, the control method for the cleaning system also includes:

[0215] S300: Controls the spray assembly to spray cleaning fluid onto the inner wall of housing 1.

[0216] Therefore, the spray assembly can pre-wet the inner wall of the housing 1, improving the cleaning effect of dried stains. Alternatively, the liquid sprayed by the spray assembly can wash away the dirt that has been scraped off by the cleaning component 32, reducing the re-adhesion of dirt to the inner wall of the housing 1 or its accumulation on the cleaning path, making the cleaning component 32 more efficient and thorough in cleaning.

[0217] In addition, the spray assembly can be operated separately from the moving part 3, making it more flexible and meeting the cleaning needs of different scenarios, with a higher level of intelligence.

[0218] For example, for stubborn stains, they can be sprayed first by the spray assembly and then scraped by the cleaning component 32.

[0219] For example, when a user wants to quickly clean the inner wall of the enclosure 1, when the inner wall of the enclosure 1 has only slight dirt or requires some routine maintenance, the inner wall of the enclosure 1 can be sprayed with water using the spray assembly without scraping.

[0220] As another example, the spray assembly and the cleaning component 32 can be used simultaneously to perform spraying and scraping operations to achieve a powerful cleaning mode and better clean the inner wall of the housing 1.

[0221] In some embodiments of this application, such as Figure 10 As shown, the control method for the cleaning system also includes:

[0222] S400: In response to the end of the self-cleaning command, a cleaning command for the wastewater tank 100 is issued.

[0223] In some embodiments, after the cleaning device returns to the base station, it initiates self-cleaning of the roller brush assembly. That is, the base station can clean the roller brush assembly that has become soiled during the cleaning process. Wastewater generated during cleaning is sucked into the wastewater tank 100 through the suction port. After self-cleaning is complete, the controller 200 can automatically issue a cleaning command for the wastewater tank 100 in response to the self-cleaning command. Therefore, the user only needs to issue one command (the self-cleaning command for the roller brush assembly) or even no command at all (automatic initiation of the roller brush assembly's self-cleaning after the cleaning device is detected supported on the base) to complete the self-cleaning process from the roller brush assembly to the wastewater tank 100, resulting in a higher degree of automation and more convenient operation.

[0224] Furthermore, the cleaning command for the wastewater tank 100 is initiated immediately after the self-cleaning of the roller brush assembly is completed. This reduces the possibility of dirt adhering to the inner wall of the tank 1 for an extended period, forming stubborn stains, and also reduces the possibility of bacteria and odor generation.

[0225] In addition, many users may forget to clean the wastewater tank 100 separately. Automating the cleaning of the wastewater tank 100 allows for timely maintenance, thereby maintaining it in good working condition for a long time and extending the service life and reliability of the equipment.

[0226] The controller 200 sequentially completes the two cleaning tasks (self-cleaning of the roller brush assembly and cleaning of the wastewater tank 100) in a continuous cycle, which can reduce the number of standby wake-ups of the cleaning system and thus save total time.

[0227] The methods described above are not in any particular order, unless otherwise specified.

[0228] This application also provides a controller 200. For example... Figure 11 As shown, the controller 200 includes a processor 201 and a memory 202. The memory 202 stores machine-readable instructions 2021 that can be executed by the processor 201. When the controller 200 is running, the machine-readable instructions 2021 are executed by the processor 201 to perform the control method of the cleaning system of this application.

[0229] The various components in controller 200 are coupled together via bus system 203. It should be understood that bus system 203 is used to implement communication connections between these components. Bus system 203 includes, in addition to a data bus, a power bus, a control bus, and a status signal bus, etc. However, for clarity, in... Figure 11 The general designated all buses as Bus System 203.

[0230] It should be understood that memory 202 can be volatile memory 202 or non-volatile memory 202, or may include both volatile and non-volatile memory 202.

[0231] The memory 202 in this embodiment is used to store various types of data to support the operation of the cleaning equipment. This data may include, for example, any computer instructions for operating on the cleaning equipment. For example, machine-readable instructions 2021. Instructions for implementing the control method of the cleaning equipment according to this embodiment may be included in machine-readable instructions 2021.

[0232] This application also provides a computer-readable storage medium. A computer program is stored on the computer-readable storage medium. The computer program, when executed by processor 201, performs a control method for the cleaning system.

[0233] It should be noted that the storage medium in the embodiments of this application can be implemented by any type of volatile or non-volatile storage device, or a combination thereof. The non-volatile memory 202 can be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a magnetic random access memory (FRAM), a flash memory, a magnetic surface memory, an optical disc, or a compact disc read-only memory (CD-ROM). The magnetic surface memory 202 can be a disk storage device 202 or a magnetic tape storage device 202.

[0234] The volatile memory 202 may be random access memory (RAM) 202, which serves as an external cache. By way of example, but not limitation, many forms of RAM are available, such as static random access memory (SRAM), synchronous static random access memory (SSRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDRSDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synclink dynamic random access memory (SLDRAM), and direct memory bus random access memory (DRRAM). The storage media described in the embodiments of this application are intended to include, but are not limited to, these and any other suitable types of memory 202.

[0235] Those skilled in the art will understand that all or part of the steps of the above method embodiments can be implemented by hardware associated with program instructions. The aforementioned instructions can be stored in a computer-readable storage medium. When executed, these instructions perform the steps of the above method embodiments.

[0236] The aforementioned storage media include: mobile storage devices, read-only memory (ROM), random access memory (RAM), magnetic disks or optical disks, and other media capable of storing program code.

[0237] As a concrete example, the wastewater tank 100 of a handheld floor scrubber (cleaning equipment) consists of a wastewater cylinder (tank body 1) and a top cover (cover body 2). The top cover and wastewater cylinder are assembled together by friction and are detachably connected. The wastewater cylinder integrates an air duct to connect to the air intake (air outlet 23) on the top cover, realizing the function of sucking up wastewater and garbage. The top cover integrates components including the top cover body (cover body 21), garbage trough (movable body 31), drive motor (cleaning component), gear (first gear 71), rack (first rack 72), water level detection electrode (water level detection device 4), and filter screen (first filter element 24). Among them, the top cover body integrates the air intake, air duct, and linear slide (first guide element 91). A rubber strip (cleaning element 32) with the same shape as the inner wall of the wastewater cylinder is embedded in the garbage trough.

[0238] The garbage bin has slots (filter holes 6) to filter garbage. The garbage bin is slidably connected to the upper cover via a linear slide (second guide 92). The rack is fixedly connected to the garbage bin by screws or integral injection molding. The rack is slidably connected to the upper cover via a linear slide. The gear is fixedly connected to the output shaft (output section) of the drive motor. The drive motor is fixedly connected to the upper cover. The motor is equipped with a waterproof and dustproof shell (protective component). The gear, rack, and drive motor output shaft are covered with waterproof and dustproof shells. A cleaning cotton swab (cleaning component 32) is provided around the garbage bin, shaped like the inner wall of a sewage tank.

[0239] Specifically, the motor drives the gear to rotate, and the gear meshes with the rack, converting the rotational motion of the gear into the up-and-down movement of the rack (movement along the first direction). The rack is fixedly connected to the garbage trough, so the garbage trough and the rubber strip fixed to it can move up and down with the rack. The relative displacement between the rubber strip and the inner wall of the sewage tank can be achieved by setting a switch (position detection component) between the rack and the upper cover body or by detecting the motor current, thereby realizing the self-cleaning function of the inner wall of the sewage tank.

[0240] In addition, the cleaning process set by the program is as follows: the handheld floor scrubber is placed back at the base station to start the self-cleaning program. After the roller brush finishes cleaning, the wastewater is discharged. Then, clean water is sucked in from the roller brush and poured into the wastewater tank 100 to the set water line. The motor drives the waste bin to scrape the wastewater tank wall up and down repeatedly. After scraping for a period of time, the wastewater is discharged, and the self-cleaning ends. Optionally, after the wastewater is discharged, clean water is introduced into the wastewater tank 100 through the clean water pipe in the main unit. After the wastewater is discharged, a spray device is used to spray clean water into the wastewater tank to rinse the wastewater tank, and then the wastewater is drained to complete the self-cleaning process.

[0241] This application offers superior cleaning performance for stubborn stains adhering to the walls of the sewage tank, achieving a self-cleaning effect through scraping the tank wall. The self-cleaning structure effectively removes residual contaminants from the walls of the sewage tank 100, reducing prolonged contaminant retention and thus effectively inhibiting bacterial growth and odor generation, improving the hygiene of the equipment. Furthermore, the self-cleaning structure enhances the equipment's usability. Through a timed self-cleaning program, manual cleaning by the user is unnecessary, resulting in a high degree of automation and reducing the likelihood of users forgetting to clean the sewage tank 100. This also minimizes damage to the sewage tank 100 from contaminants, extending the equipment's lifespan.

[0242] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. 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.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
