Description

Technical Field

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

[0002] With the advancement of smart home cleaning equipment, products with hot water mopping functions have gained widespread market popularity due to their significantly improved cleaning performance. Currently, traditional cleaning equipment mostly uses independent heating elements to heat the mop or washing water. This approach not only increases overall energy consumption but also leads to a more complex system structure and larger footprint. Furthermore, during operation, the large amount of heat generated by the drive motor is typically dissipated directly to the outside through the cooling system, resulting in considerable heat energy waste; simultaneously, heat accumulation in the drive motor reduces work efficiency. Against this backdrop, how to achieve efficient energy recovery and utilization within the existing equipment structure, thereby improving the overall system energy efficiency, has become a key technical problem that the industry urgently needs to solve. Utility Model Content

[0003] This application provides a cleaning device through multiple embodiments, which aims to solve the problem that the heat generated by the drive components in the cleaning device cannot be recovered and utilized, and achieve the dual effect of waste heat recovery and hot water cleaning.

[0004] In a first aspect, this application provides a cleaning device, which includes a body, a water tank, and a cleaning module. The water tank is disposed within the body; the cleaning module is disposed on the side of the body near the surface to be cleaned, and the cleaning module includes a drive assembly, a cleaning component, and a liquid heating assembly. The drive assembly drives the cleaning component to move to clean the surface to be cleaned, and the liquid heating assembly is connected to the drive assembly. The liquid heating assembly is configured to draw cleaning liquid from the water tank and conduct the heat generated by the drive assembly during operation to the cleaning liquid.

[0005] In this way, by integrating the liquid heating component into the drive component that generates heat during operation, the cleaning fluid is heated synchronously during delivery. This achieves two benefits: firstly, mopping with hot water utilizes heat energy to promote stain dissolution, improve cleaning efficiency, and enhance sterilization; secondly, it cleverly recovers and utilizes the waste heat inevitably generated during the operation of the drive component, effectively reducing the overall energy consumption of the system and achieving a dual improvement in cleaning performance and energy utilization efficiency.

[0006] Optionally, the liquid heating assembly includes a heat exchange tube trough and a water inlet pipe. The water inlet pipe is disposed between the machine body and the drive assembly and is used to connect the water tank and the heat exchange tube trough. The heat exchange tube groove is fitted onto the outer surface of the drive assembly and is used to exchange heat with the drive assembly through the outer surface.

[0007] In this way, by fitting the heat exchange tube grooves to the drive components, the heat exchange area can be increased so as to absorb and utilize the heat generated by the drive components to the greatest extent.

[0008] Optionally, the liquid heating assembly further includes a water outlet pipe, which is connected to the outlet of the heat exchange tube trough and extends laterally outward from the side wall of the heat exchange tube trough. The end of the water outlet pipe has a water outlet, from which heated cleaning liquid flows out and drips onto the cleaning component.

[0009] In this way, the cleaning liquid, which has been heated in the heat exchange tube tank, is discharged through the water outlet pipe and finally drips from the water outlet onto the cleaning components for cleaning.

[0010] Optionally, the liquid heating assembly further includes a sealing cover plate, which covers the heat exchange tube groove on the side near the machine body; the water inlet pipe passes through the sealing cover plate and connects the water tank and the heat exchange tube groove.

[0011] In this way, the sealing cover plate ensures the airtightness of the heat exchange tube tank and prevents the cleaning fluid inside the heat exchange tube tank from leaking.

[0012] Optionally, the water outlet pipe is located on one side of the outer perimeter of the sealing cover; In the axial direction of the drive assembly, the height of the water outlet is higher than that of the heat exchange tube trough and lower than that of the water inlet pipe.

[0013] In this way, the outlet pipe is located on one side of the outer perimeter of the sealing cover, optimizing the spatial layout. The height difference between the outlet pipe, the heat exchange tube, and the inlet pipe ensures that the cleaning fluid is fully heated and flows smoothly.

[0014] Optionally, the outer peripheral wall of the drive assembly is provided with a first connection hole, and the outer peripheral wall of the sealing cover is provided with a second connection hole corresponding to the first connection hole; the first connection hole and the second connection hole are engaged by fasteners to fix the sealing cover to the drive assembly and seal the heat exchange tube groove.

[0015] Thus, by passing fasteners through the first and second connection holes, the sealing cover is secured to the drive assembly, while simultaneously sealing the heat exchange tube groove.

[0016] Optionally, the heat exchange tube is arranged around the drive assembly along the axial direction, forming a fluid path connecting the inlet pipe and the outlet pipe.

[0017] In this way, the fluid path design increases the contact area between the heat exchange tube and the drive component, ensuring the efficiency of waste heat utilization of the drive component and the actual effect of hot water cleaning.

[0018] Optionally, the heat exchange tube trough includes a first ring segment and a second ring segment that are interconnected. The first ring segment and the second ring segment are concentrically arranged. The diameter of the first ring segment is smaller than the diameter of the second ring segment. The first ring segment is connected to the water inlet pipe, and the second ring segment is connected to the water outlet pipe.

[0019] In this way, by directly extending the heating path through the interconnected first and second ring segments, the waste heat energy is fully utilized, ensuring that the cleaning fluid is heated properly.

[0020] Optionally, the heat exchange tube groove is integrated on the side of the drive assembly away from the surface to be cleaned.

[0021] In this way, with the heat exchange tubes located away from the surface to be cleaned, the liquid channels and heating components within receive better physical protection, reducing the possibility of moisture, dust accumulation, and physical impact, thus extending their service life. Simultaneously, heat is locked inside the equipment, ensuring the heat exchange efficiency of the heat exchange tubes.

[0022] Optionally, the drive assembly includes a rotor and a stator, with the heat exchange tubes integrated on the side of the stator away from the rotor, and the heat generated during rotor operation being conducted to the heat exchange tubes via the stator.

[0023] In this way, by integrating the heat exchange tube slots on the side of the stator away from the rotor, the shortest heat exchange path is achieved, ensuring heat exchange efficiency.

[0024] Secondly, this application provides a cleaning system, the cleaning system including a base station and the cleaning equipment described in any of the above claims, the base station being used to supply power to the cleaning equipment and / or to clean the cleaning equipment.

[0025] This application provides a cleaning device and a cleaning system. The cleaning device includes a body, a water tank, and a cleaning module. The water tank is located inside the body; the cleaning module is located on the side of the body near the surface to be cleaned. The cleaning module includes a drive component, a cleaning element, and a liquid heating component. The drive component drives the cleaning element to move and clean the surface. The liquid heating component is connected to the drive component and is configured to draw cleaning fluid from the water tank and transfer the heat generated by the drive component during operation to the cleaning fluid. Thus, by integrating the liquid heating component into the drive component that generates heat during operation, the cleaning fluid is simultaneously heated during delivery. This achieves two benefits: firstly, it enables mopping with hot water, utilizing heat energy to promote stain dissolution, improve cleaning efficiency, and enhance sterilization; secondly, it cleverly recovers and utilizes the waste heat inevitably generated by the drive component during operation, effectively reducing the overall energy consumption of the system and achieving a dual improvement in cleaning performance and energy utilization efficiency.

[0038] As home cleaning equipment becomes increasingly intelligent, products with hot water mopping capabilities are gaining popularity among consumers due to their significant improvements in cleaning efficiency and hygiene. Hot water effectively softens dirt, enhances stain removal, and inhibits bacterial growth to some extent, thus meeting users' pursuit of a higher quality home environment.

[0039] Currently, most cleaning equipment in related technologies uses independent electric heating elements to heat the mop or washing water. While this solution can achieve basic hot water cleaning, it also has significant drawbacks: it not only increases the overall energy consumption of the equipment but also makes the internal structure more complex and increases the number of parts, resulting in increased weight and cost of the entire machine and decreased space utilization.

[0040] On the other hand, the drive motor in cleaning equipment generates a large amount of heat during operation. This heat is usually regarded as "waste heat" in traditional designs and is simply discharged directly to the outside through the heat dissipation module, failing to be effectively utilized. At the same time, the heat cannot be dissipated during use, resulting in a decrease in the drive motor's working efficiency.

[0041] Therefore, in this embodiment of the application, within the structural framework of existing cleaning equipment, the waste heat generated during the operation of the drive motor is efficiently recovered and utilized, and applied to the hot water cleaning function. This helps to reduce system energy consumption, simplify structural design, and achieve a dual improvement in cleaning performance and energy utilization efficiency.

[0042] The present application will now be described in detail with reference to the accompanying drawings.

[0043] Please see Figure 1 and Figure 2 This application provides a cleaning device 100 and a cleaning system. The cleaning device 100 includes a body 101, a water tank 102, and a cleaning module 103. The water tank 102 is disposed inside the body 101. The cleaning module 103 is disposed on the side of the body 101 near the surface to be cleaned. The cleaning module 103 includes a drive assembly 10, a cleaning component 20, and a liquid heating assembly 30. The drive assembly 10 drives the cleaning component 20 to move to clean the surface to be cleaned. The liquid heating assembly 30 is connected to the drive assembly 10 and is configured to draw cleaning liquid from the water tank 102 and conduct the heat generated by the drive assembly 10 during operation to the cleaning liquid.

[0044] In this way, by integrating the liquid heating component 30 onto the drive component 10 which generates heat during operation, the cleaning fluid is heated synchronously during delivery. This achieves two benefits: firstly, mopping with hot water utilizes heat energy to promote stain dissolution, improve cleaning efficiency, and enhance sterilization; secondly, it cleverly recovers and utilizes the waste heat inevitably generated during the operation of the drive component 10, effectively reducing the overall energy consumption of the system and achieving a dual improvement in cleaning performance and energy utilization efficiency.

[0045] In this embodiment, the type of cleaning solution is not limited to meet different needs. This specification uses room temperature water as an example for illustration.

[0046] In this embodiment, using hot water for cleaning can promote stain dissolution, improve cleaning efficiency, and enhance sterilization. However, directly heating the room-temperature water in the water tank 102 requires significant energy, shortening the operating time of the sweeper and other cleaning equipment 100, and reducing its efficiency. Simultaneously, the drive component 10 generates heat during floor cleaning, and the accumulation of heat can affect its performance. In traditional designs, to ensure the efficiency of the drive component 10, the heat dissipation performance of the cleaning equipment 100 is increased to allow waste heat to dissipate. This would waste the heat generated by the drive component 10.

[0047] In this embodiment, the heat generated during the operation of the drive component 10 can be effectively utilized to heat the cleaning water, thereby achieving the effect of "hot water cleaning". Specifically, by connecting the liquid path heating component 30 to the drive component 10, the cleaning fluid absorbs the waste heat conducted from the drive component 10 when it is drawn and flows through the liquid path heating component 30, thus being continuously heated during the transportation process. This design not only cleverly transforms waste heat energy into a beneficial resource for improving cleaning effects and realizing the advantages of hot water for decontamination and sterilization, but also fundamentally avoids additional energy consumption, achieving a dual improvement in cleaning performance and equipment energy efficiency.

[0048] Please see Figure 2 and Figure 3 In some embodiments, the liquid heating assembly 30 includes a heat exchange tube trough 31 and a water inlet pipe 32. The water inlet pipe 32 is disposed between the body 101 and the drive assembly 10 and is used to connect the water tank 102 and the heat exchange tube trough 31. The heat exchange tube groove 31 is attached to the outer surface of the drive assembly 10 and is used to exchange heat with the drive assembly 10 through the outer surface.

[0049] Thus, by fitting the heat exchange tube groove 31 to the drive component 10, the heat exchange area can be increased so as to absorb and utilize the heat generated by the drive component 10 to the greatest extent.

[0050] In this embodiment, the liquid heating assembly 30 constitutes a highly efficient heat recovery and conversion system. Its specific workflow is as follows: First, the inlet pipe 32 is responsible for exporting the room-temperature cleaning liquid from the water tank 102 and guiding it to the core heating area (i.e., the heat exchange tube trough 31, which is arranged in close contact with the outer surface of the drive assembly 10). This close-fitting design maximizes the contact area between the heat exchange tube trough 31 and the heating surface of the drive assembly 10, thereby establishing a highly efficient heat conduction path. When the drive assembly 10 generates a large amount of waste heat due to high-speed operation, this heat will preferentially pass through this path and be efficiently conducted to the wall of the heat exchange tube trough 31. At this time, the cleaning liquid continuously flowing through the heat exchange tube trough 31 serves as an ideal cooling medium and heat carrier. During the flow of the cleaning liquid, through sufficient and continuous heat exchange with the heated tube trough wall, a large amount of waste heat generated by the drive assembly 10, which would otherwise be wasted, is absorbed stably and efficiently, thereby achieving a significant increase in its own temperature. This process not only successfully converts waste heat into valuable clean energy, but also provides a highly efficient active heat dissipation solution for the drive component 10, fundamentally optimizing the system's energy flow and thermal management.

[0051] Please see Figure 2 and Figure 3 In some embodiments, the liquid heating assembly 30 further includes a water outlet pipe 33, which is connected to the outlet of the heat exchange tube trough 31 and extends laterally outward from the side wall of the heat exchange tube trough 31; The end of the water outlet pipe 33 has a water outlet 331, from which heated cleaning liquid flows out and drips onto the cleaning component 20.

[0052] Thus, the cleaning fluid, which has been heated in the heat exchange tube 31, is discharged through the water outlet pipe 33 and finally drips from the water outlet 331 onto the cleaning component 20 for cleaning.

[0053] In this embodiment, the water outlet pipe 33 extends horizontally outward from the side wall of the heat exchange tube trough 31 in a direction approximately perpendicular to the axis of the drive assembly 10. The heated cleaning fluid is directed to the cleaning component 20, and then hot water drips onto the cleaning component 20 from the water outlet 331. This allows the cleaning device 100 to utilize heat energy to promote stain dissolution, improve cleaning efficiency, and enhance sterilization. While completing basic stain removal, it further improves the hygiene level of the home environment, achieving a dual optimization of cleaning efficiency and health protection.

[0054] Please see Figure 2 and Figure 3 In some embodiments, the liquid heating assembly 30 further includes a sealing cover plate 34, which covers the heat exchange tube trough 31 on the side near the body 101; the water inlet pipe 32 passes through the sealing cover plate 34 and connects the water tank 102 and the heat exchange tube trough 31.

[0055] In this way, the sealing cover plate 34 ensures the airtightness of the heat exchange tube trough 31 and prevents the cleaning fluid in the heat exchange tube trough 31 from leaking.

[0056] In this embodiment, the cover plate tightly covers the side of the heat exchange tube trough 31 facing the interior of the body 101, thereby structurally forming a closed flow channel chamber. This completely prevents the heated cleaning fluid from leaking into other components inside the upper body 101 within the critical heat exchange area, ensuring the electrical safety and stable operation of the equipment. Simultaneously, the water inlet pipe 32 directly passes through and is fixed to the sealing cover plate 34, providing a reliable transport path for the cleaning fluid to flow from the water tank 102 into the heat exchange tube trough 31. This simplifies the overall assembly process, reduces heat loss during heat exchange, and improves the efficiency of recovering and utilizing waste heat from the drive assembly 10.

[0057] In this embodiment, the sealing cover 34 can be made of plastic (such as plastic with certain high-temperature resistance) to reduce production difficulty and costs. Meanwhile, the heat exchange tube trough 31 can be made of metal to improve heat exchange efficiency with the drive assembly 10.

[0058] Please see Figure 2 and Figure 3 In some embodiments, the water outlet pipe 33 is disposed on one side of the outer periphery of the sealing cover plate 34; In the axial direction of the drive assembly 10, the height of the outlet 331 is higher than that of the heat exchange tube 31 and lower than that of the inlet pipe 32.

[0059] Thus, the outlet pipe 33 is located on one side of the outer circumference of the sealing cover plate 34, optimizing the spatial layout. The height difference between the outlet pipe 33, the heat exchange tube trough 31, and the inlet pipe 32 ensures sufficient heating and smooth flow of the cleaning fluid.

[0060] In this embodiment, the water outlet pipe 33 of the liquid heating assembly 30 is located on one side of the outer circumference of the sealing cover plate 34, effectively utilizing the radial space of the module and avoiding the water outlet pipe 33 competing for space with other components in the axial direction, thus achieving a compact and modular overall structure. Simultaneously, by arranging the water outlet pipe 33, heat exchange tube 31, and water inlet pipe 32 in a stepped height difference arrangement in the axial direction of the drive assembly 10—that is, the water inlet pipe 32 is the highest, the water outlet pipe 33 is in the middle, and the heat exchange tube 31 is the lowest—a highly efficient thermal and fluid system is formed. Firstly, this ensures that the low-temperature cleaning liquid, after entering the heat exchange tube 31 from the highest water inlet pipe 32, can remain sufficiently in the heat exchange tube 31 and absorb the waste heat generated by the drive assembly 10, achieving sufficient heating of the cleaning liquid. Subsequently, the heated cleaning liquid, due to density changes and gravity, can naturally and smoothly discharge through the appropriately positioned water outlet pipe 33. This avoids the ineffective accumulation of heat in the pipe trench and ensures that hot water is delivered to the cleaning component 20 in a timely and complete manner. While optimizing space utilization, it significantly improves heat exchange efficiency and the reliability of fluid flow.

[0061] Please see Figure 2 In some embodiments, the outer peripheral wall of the drive assembly 10 is provided with a first connection hole 11, and the outer peripheral wall of the sealing cover plate 34 is provided with a second connection hole 341 corresponding to the first connection hole 11; the first connection hole 11 and the second connection hole 341 are engaged by fasteners to fix the sealing cover plate 34 to the drive assembly 10 and seal the heat exchange tube groove 31.

[0062] Thus, by passing fasteners through the first connection hole 11 and the second connection hole 341, the sealing cover 34 is fastened to the drive assembly 10, while the sealing cover 34 seals the heat exchange tube groove 31.

[0063] In this embodiment, the liquid heating assembly 30 utilizes fasteners (such as bolts) that sequentially pass through the second connecting hole 341 on the outer peripheral wall of the sealing cover 34 and the corresponding first connecting hole 11 on the outer peripheral wall of the drive assembly 10, generating a reliable axial clamping force through tightening. This securely locks the sealing cover 34 onto the drive assembly 10, forming a stable mechanical connection to resist vibrations generated during equipment operation and ensure long-term structural stability. Simultaneously, this clamping force evenly presses between the sealing cover 34 and the mating surface of the drive assembly 10, allowing the plastic sealing cover 34 to elastically deform and tightly fill microscopic gaps. This forms a complete and reliable high-pressure sealing band around the entire opening of the heat exchange tube trough 31, ensuring that the heated cleaning fluid is completely sealed within the flow channel cavity formed by the heat exchange tube trough 31 and the sealing cover 34. This eliminates the risk of liquid leakage into the drive assembly 10, ensuring safe operation and efficient heat exchange of the equipment.

[0064] Please see Figure 3and Figure 4 In some embodiments, the heat exchange tube trough 31 is arranged around the drive assembly 10 in the axial direction and forms a fluid path connecting the inlet pipe 32 and the outlet pipe 33.

[0065] In this way, the contact area between the heat exchange tube trough 31 and the drive component 10 is increased by the surrounding fluid path design, ensuring the waste heat utilization efficiency of the drive component 10 and the actual effect of hot water cleaning.

[0066] In this embodiment, the liquid heating assembly 30 employs a fluid path, such as a spiral or annular one, designed with the heat exchange tube 31 encircling the outer periphery of the drive assembly 10. This significantly increases the effective contact area between the inner wall of the heat exchange tube 31 and the heating drive assembly 10 during the water inlet to outlet process, allowing the waste heat generated by the drive assembly 10 during operation to be conducted more quickly and fully into the cleaning fluid flowing through the heat exchange tube 31. Simultaneously, the encircling design of the heat exchange tube 31 provides a longer fluid path, which also extends the residence time of the cleaning fluid near the heat source, ensuring that the cold liquid is gradually and uniformly heated to the ideal temperature. This ensures efficient recovery and utilization of waste heat from the drive assembly 10, improving the actual effectiveness of hot water cleaning in dissolving stains and removing bacteria.

[0067] Of course, in other embodiments, the heat exchange tube trough 31 can also be laid in other forms, which are not limited here, in order to meet different needs.

[0068] Please see Figure 3 and Figure 4 In some embodiments, the heat exchange tube trough 31 includes a first ring segment 311 and a second ring segment 312 that are interconnected. The first ring segment 311 and the second ring segment 312 are concentrically arranged. The diameter of the first ring segment 311 is smaller than the diameter of the second ring segment 312. The first ring segment 311 is connected to the water inlet pipe 32, and the second ring segment 312 is connected to the water outlet pipe 33.

[0069] In this way, the heating path is directly lengthened by the interconnected first ring segment 311 and second ring segment 312, ensuring that waste heat energy is fully utilized and that the cleaning liquid is heated properly.

[0070] In this embodiment, the heat exchange tube trough 31 adopts a structure with a concentrically arranged and interconnected first ring segment 311 and second ring segment 312. The smaller diameter first ring segment 311 connects to the inlet water pipe 32, and the larger diameter second ring segment 312 connects to the outlet water pipe 33, thus forming a continuous and progressive spiral fluid path from the inside to the outside. In this way, the double-ring segment layout greatly extends the length of the total flow channel within a limited axial space, increasing the heat exchange area between the cleaning fluid and the housing of the drive component 10. At the same time, it can guide the low-temperature cleaning fluid to be preheated from the inner first ring segment 311, and then flow smoothly to the outer second ring segment 312 for deep heating. This gradual temperature increase method effectively utilizes the overall temperature field of the heat source, achieving highly efficient recovery and utilization of waste heat from the drive component 10, and ensuring that the outlet water temperature reaches the optimal cleaning effect.

[0071] Please see Figure 1 and Figure 2 In some embodiments, the heat exchange tube groove 31 is integrated on the side of the drive assembly 10 away from the surface to be cleaned.

[0072] In this way, with the heat exchange tube trough 31 located away from the surface to be cleaned, the liquid channels and heating components within it receive better physical protection, reducing the possibility of moisture, dust accumulation, and physical impact, thus extending its service life. Simultaneously, it locks heat inside the equipment, ensuring the heat exchange efficiency of the heat exchange tube trough 31.

[0073] In this embodiment, by integrating the heat exchange tube trough 31 onto the side of the drive assembly 10 furthest from the surface to be cleaned, the physical protection environment of the liquid circuit and heating assembly is enhanced. This effectively avoids everyday impacts from the ground, liquid splashes, and dust intrusion, thereby significantly reducing the risk of failure and extending the service life of core components. Simultaneously, this "built-in, top-mounted" layout confines the waste heat generated during the operation of the drive assembly 10 within the equipment, forming a relatively closed heat circulation zone. This prevents ineffective heat dissipation to the bottom of the equipment and the external environment, forcing heat energy to be more concentratedly transferred to the cleaning liquid flowing through the heat exchange tube trough 31. This fundamentally guarantees and improves the overall heat exchange efficiency of the system, ensuring that the waste heat recovery and hot water cleaning effects meet expectations.

[0074] Please see Figures 2 to 4 In some embodiments, the drive assembly 10 includes a rotor 12 and a stator 13, with a heat exchange tube 31 integrated on the side of the stator 13 away from the rotor 12, and the heat generated by the rotor 12 during operation is conducted to the heat exchange tube 31 via the stator 13.

[0075] In this way, by integrating the heat exchange tube groove 31 on the side of the stator 13 away from the rotor 12, the shortest heat exchange path is achieved, ensuring heat exchange efficiency.

[0076] In this embodiment, the heat exchange tube trough 31 is directly integrated into the stator 13 through integral processing. The stator 13 can be made of metal to construct an efficient heat conduction path and improve heat exchange efficiency. Specifically, the large amount of heat generated by the rotor 12 of the drive assembly 10 during operation is first transferred from the rotor 12 to the stator 13, and then conducted through the stator 13 to the heat exchange tube trough 31 integrated with the stator 13, used to heat the cleaning fluid flowing through the heat exchange tube trough 31. In this way, the waste heat generated by the motor can be efficiently and directionally recovered, improving heating efficiency. At the same time, the flowing cleaning fluid can also serve as an efficient cooling medium, continuously dissipating heat from the stator 13, optimizing the operating temperature of the drive assembly 10, and improving the operating efficiency and service life of the drive assembly 10.

[0077] Please see Figure 5 This application provides a cleaning system, which includes a base station 201 and a cleaning device 100 as described above. The base station 201 is used to supply power to the cleaning device 100 and / or to clean the cleaning device 100.

[0078] In this embodiment, the type of cleaning system is not limited to meet various needs. The cleaning system includes a base station 201 and the aforementioned cleaning device 100. The base station 201 is used to supply power to the cleaning device 100 and / or to clean the cleaning device 100. This cleaning system can possess all the technical features and effects of the aforementioned cleaning device 100, resulting in better cleaning and self-cleaning effects, as well as better operational stability and service life, thus improving the user experience.

[0079] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0080] The functions and effects of this embodiment can be explained by referring to the foregoing implementation methods, and will not be repeated here.
