Description

A cleaning component, cleaning equipment, and cleaning system

[0001] This application claims priority to Chinese Patent Application No. 202422796731.3, filed on November 15, 2024, entitled "A Cleaning Component, Cleaning Equipment and Cleaning System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of cleaning technology, specifically to a cleaning component, cleaning equipment, and cleaning system. Background Technology

[0003] Existing cleaning equipment generally includes a mopping module for wet mopping, but this usually uses room temperature water, resulting in poor effectiveness against stubborn stains and oil. The cleaning effect is further compromised, especially at lower room temperatures. Therefore, the cleaning capabilities of cleaning equipment need to be improved. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a cleaning component, cleaning equipment and cleaning system to improve the technical problem of poor cleaning effect caused by the use of room temperature water for cleaning in existing cleaning equipment.

[0005] To achieve the above and other related objectives, this utility model provides a cleaning component, which includes: a cloth mounting bracket and a cloth; the cloth is mounted on the cloth mounting bracket; wherein the cloth mounting bracket and / or the cloth includes a phase change material, the phase change material being thermally connected to the cloth to absorb heat from a heat source when the cloth is not in a cleaning operation, and to release heat to the cloth when the cloth is in a cleaning operation; the non-cleaning operation includes at least a portion of the cleaning process, drying process, and soaking and heating process of the cloth.

[0006] The advantages of this design are as follows: By incorporating a phase change material (PCM), the cleaning component can heat the mop during non-cleaning operations, enabling heated mopping and thus improving cleaning effectiveness. Simultaneously, due to the high energy density of PCM, it can absorb or release a significant amount of heat during the phase change process, storing substantial thermal energy in a relatively small volume or mass. This saves installation space and reduces the overall weight of the cleaning component. Furthermore, since the PCM only needs to absorb heat from the cleaning fluid or the heating element used to heat the fluid during mop washing, eliminating the need for an additional heat source within the cleaning component, the structure is safer, simpler, and more energy-efficient.

[0007] In one example of the cleaning component of this utility model, the heat source includes a heating device and / or hot water.

[0008] The beneficial effects of this setup are: by setting the heat source as a heating device and / or hot water, the heating efficiency of the cloth can be improved, which in turn can improve the heat absorption efficiency of the phase change material, thereby improving the cleaning efficiency of the cleaning components.

[0009] In one example of the cleaning component of this utility model, the side of the cloth mounting bracket away from the cloth is provided with a connecting part that can be detachably connected to the drive component. The connecting part includes a magnetic attraction structure that can be attracted to the drive shaft of the drive component, or the connecting part includes a snap-fit ​​structure that can be engaged with the drive component.

[0010] The advantages of this design are: by using magnetic and snap-fit ​​structures, no other tools are needed when installing the connection part and the drive assembly, making installation and disassembly very convenient.

[0011] In one example of the cleaning component of this utility model, a buffer portion is provided on the outer periphery of the cloth mounting bracket to absorb the impact force of the edge of the cleaning component.

[0012] The benefits of this design are twofold: First, by incorporating a buffer around the outer perimeter of the cleaning cloth mounting bracket, it effectively mitigates the impact of external collisions on the cleaning components, reducing wear and tear on the bracket and extending its lifespan. Second, the buffer structure also minimizes scratches and impacts on furniture and walls during cleaning, reducing damage and minimizing noise generated during the cleaning process.

[0013] In one example of the cleaning component of this utility model, the buffer part includes a soft rubber structure, which has multiple deformable hollow areas.

[0014] The advantages of this design are as follows: By incorporating a soft rubber structure with multiple deformable perforated areas, the soft rubber structure can be thermoformed onto the outer periphery of the cloth mounting bracket, making installation convenient and eliminating the need for additional mechanical connections. Furthermore, the combination of the soft rubber structure and the deformable perforated areas provides excellent cushioning around the outer periphery of the cloth mounting bracket.

[0015] In one example of the cleaning component of this utility model, the cloth mounting bracket is provided with a sealed cavity, which is filled with a phase change material.

[0016] The beneficial effects of this design are as follows: By creating a sealed cavity on the rag mounting bracket and filling the cavity with phase change material (PCM), this design not only prevents leakage of PCM during the phase change process, ensuring its heat storage performance, but also reduces the impact of external factors (such as air and moisture) during the phase change process, thus maintaining the stability of PCM performance.

[0017] In one example of the cleaning component of this utility model, the cloth mounting bracket is also provided with an opening communicating with the sealed cavity, through which liquid phase change material is injected into the sealed cavity, and a sealing cap is closed at the opening.

[0018] The advantages of this design are as follows: By creating an opening on the cloth mounting bracket that connects to the sealed cavity, liquid phase change material can be injected into the sealed cavity through the opening. This allows the sealed cavity to be manufactured as a single, integral structure, making it easier to ensure its sealing performance. Simultaneously, the opening also allows for easy monitoring of the phase change material's condition within the sealed cavity, enabling timely understanding of changes in its heat storage performance.

[0019] In one example of the cleaning component of this utility model, the cloth mounting bracket includes an upper cover and a lower cover, which are sealed together to form a sealed cavity; the cloth mounting bracket also includes hot melt adhesive, which is used to heat-melt the upper cover and the lower cover together.

[0020] The advantages of this design are as follows: By using an upper cover and a lower cover, which are connected to form a sealed cavity, this design facilitates the separate design of the cloth mounting bracket, making injection molding easier and reducing processing costs. Furthermore, before the upper and lower covers are closed, a solid phase change material can be pre-installed within the sealed cavity. The cavity is then sealed by connecting the upper and lower covers, facilitating the installation of the solid phase change material within the sealed cavity. Additionally, by using hot melt adhesive, a fusion bond is formed between the upper and lower covers. Compared to bolt fasteners, this method offers higher connection efficiency during mass production and ensures better sealing performance. In one example of the cleaning component of this invention, the lower cover is thermally connected to the cloth, and the thermal conductivity of the lower cover is greater than that of the upper cover.

[0021] The beneficial effects of this design are as follows: By making the thermal conductivity of the lower cover greater than that of the upper cover, this design allows the heat stored in the phase change material to be quickly conducted to the cloth through the lower cover, heating the cloth and improving its heating efficiency and effect. Furthermore, it reduces heat transfer from the phase change material within the sealed cavity to the outside through the upper cover, thereby minimizing heat loss from the phase change material and further enhancing its heating effect on the cloth.

[0022] In one example of the cleaning component of this utility model, an adhesive layer is provided on the side of the upper cover that is away from the lower cover.

[0023] The beneficial effects of this design are as follows: By applying an adhesive layer to the upper cover, which has a low thermal conductivity, the exposed surface of the upper cover is effectively shielded, reducing the rate of heat exchange between the upper cover and the surrounding air. This, in turn, reduces the heat transfer from the phase change material to the outside through the upper cover. Simultaneously, the adhesive layer increases the friction between the drive shaft end face and the cloth mounting bracket, thus facilitating the disassembly of the cleaning components.

[0024] In one example of the cleaning component of this utility model, the lower cover includes heat-conducting ribs that extend at least partially into the interior of the sealing cavity.

[0025] The beneficial effects of this design are as follows: by setting heat-conducting ribs on the lower cover and extending at least partially into the interior of the sealed cavity, the contact area between the phase change material and the lower cover can be increased, thereby increasing the heat conduction efficiency between the phase change material and the lower cover, and ultimately improving the heat transfer efficiency of the phase change material to the rag, so as to ensure the hot mopping effect of the rag.

[0026] In one example of the cleaning component of this utility model, the rag includes a fabric layer, an absorbent layer and an adhesive layer connected sequentially from bottom to top. An adhesive part is provided on the side of the rag mounting bracket facing the rag, and the adhesive layer is bonded to the adhesive part. A phase change material is disposed between the fabric layer and the absorbent layer and / or between the absorbent layer and the adhesive layer.

[0027] The beneficial effects of this design are as follows: By placing the phase change material (PCM) between the fabric layer and the absorbent layer, and / or between the absorbent layer and the adhesive layer, the PCM can be fully immersed in the cleaning solution during the cleaning process. This increases the contact area between the PCM and the cleaning solution, thereby improving the heat storage efficiency of the PCM. Simultaneously, the shorter heat conduction path between the PCM and the fabric layer during cleaning reduces heat loss during the transfer of heat from the PCM to the fabric layer, further enhancing the heat conduction effect of the PCM on the fabric layer. This extends the hot mopping time of the fabric layer and further improves the cleaning effect of the mop.

[0028] In one example of the cleaning component of this utility model, the sum of the areas of the upper and lower surfaces of the absorbent layer is S1, and the area S2 of the absorbent layer covered by the phase change material is less than or equal to 1 / 2 of S1.

[0029] The beneficial effects of this setting are: setting the area S2 covered by the phase change material in the absorbent layer to be less than or equal to 1 / 2 of S1. Within this range, the water absorption performance of the absorbent layer can be satisfied to ensure the wet mopping effect of the rag, while also taking into account the heat storage requirements of the phase change material to ensure the hot mopping effect of the rag.

[0030] In one example of the cleaning component of this utility model, a sealing interlayer is provided between the fabric layer and the absorbent layer and / or between the absorbent layer and the adhesive layer, and a phase change material is filled in the sealing interlayer.

[0031] The beneficial effects of this design are: by setting up a sealed interlayer, not only can the probability of leakage during the phase change process of the phase change material be reduced, but the installation and fixation of the phase change material on the cloth can also be facilitated, reducing the difficulty of the installation process of the phase change material on the cloth.

[0032] In one example of the cleaning component of this utility model, a microcapsule layer is provided on the upper and / or lower surfaces of the absorbent layer. The microcapsule layer contains a plurality of microcapsules, and the microcapsules are filled with a phase change material.

[0033] The beneficial effects of this design are as follows: By incorporating a microcapsule layer and filling the microcapsules with phase change material (PCM), not only is leakage of the PCM during the phase change process prevented, but the microcapsule structure also makes it less likely for the PCM to leak out from the seams of the cloth, thus better retaining the PCM inside the cloth and reducing its loss during use. Simultaneously, with the same area, the microcapsule structure can increase the contact area between the PCM and the cleaning fluid, thereby improving the heat storage efficiency of the PCM.

[0034] In one example of the cleaning component of this utility model, the upper surface of the absorbent layer is coated with a plurality of spaced first microcapsule layers, and the lower surface of the absorbent layer is coated with a plurality of spaced second microcapsule layers, with the plurality of first microcapsule layers and the plurality of second microcapsule layers arranged alternately.

[0035] The advantages of this design are twofold: First, it maximizes the area of ​​the microcapsule layer on the absorbent layer while ensuring its absorbency, thereby increasing the amount of phase change material used and ensuring its thermal conductivity to the fabric layer. Second, because the first and second microcapsule layers are staggered, during mopping, when the cloth is rehydrated, the water flows from the upper surface of the absorbent layer, bypassing the staggered area, and then flows from the lower surface to the fabric layer. This increases the water flow path length within the absorbent layer, prolongs the water's residence time within the cloth, and increases the contact time between the water and the phase change material, thus increasing the water's outlet temperature and improving the hot mopping effect.

[0036] In one example of the cleaning component of this utility model, the phase change material is a solid-solid phase change material, and the cloth mounting bracket is at least partially composed of the phase change material.

[0037] The advantages of this design are as follows: This design allows for direct contact between the phase change material and the cloth, thereby reducing the heat conduction path between the two materials and further improving the heating effect of the phase change material on the cloth. Simultaneously, it eliminates the need for additional phase change material on the cloth mounting bracket, thus reducing the weight of the bracket itself and facilitating a lightweight design.

[0038] In one example of the cleaning component of this utility model, the entire cloth mounting bracket is injection molded from a phase change material.

[0039] The beneficial effects of this setup are as follows: This configuration allows for a large area and mass of phase change material (PCM) on the cloth mounting rack. This increases the contact area between the PCM and the cleaning solution during the cloth washing process, thereby improving the heat storage efficiency and heat capacity of the PCM. Consequently, it extends the heat transfer time between the PCM and the cloth during cleaning, further enhancing the effectiveness of hot mopping.

[0040] In one example of the cleaning component of this utility model, the cloth mounting bracket includes a main body, and the side of the main body facing the cloth includes a phase change material, which at least partially abuts against the cloth.

[0041] The advantages of this design are as follows: By placing the phase change material on the side of the main body facing the cloth, the main body and the phase change material can be separated. This allows for the selection of a suitable material for the main body, ensuring the support strength of the cloth mounting bracket itself and reducing the impact of the phase change material on the bracket's support strength. This also simplifies the selection of phase change material. Furthermore, since the main body covers the surface of the phase change material facing away from the cloth, using a material with low thermal conductivity for the main body can improve the heat retention of the phase change material, reducing heat loss and improving the heating effect and heating time of the cloth.

[0042] In one example of the cleaning component of this utility model, the cloth mounting bracket includes a main body made of metal, and the main body is wrapped with a phase change material.

[0043] The advantages of this design are as follows: By using a metal main body and encasing it in phase change material (PCM), the metal main body provides better support, thereby increasing the structural strength of the cloth mounting bracket. Simultaneously, because the PCM is encased in metal, the metal provides better support for the PCM, reducing the difficulty in selecting the appropriate PCM. Furthermore, encasing the PCM in the main body increases the amount of PCM used, which improves its heat storage performance and enhances its heating effect on the cloth.

[0044] The present invention also provides a cleaning device that includes the cleaning components of any of the above examples.

[0045] In one example of the cleaning equipment of this utility model, the cleaning equipment includes a body and two cleaning components. At least one cleaning component is movably connected to the body and has an inward position and an outward position relative to the body. When the cleaning component is in the outward position, it is far away from the body relative to the inward position, and the cleaning equipment can perform edge cleaning. When the cleaning component's cloth absorbs heat from the heat source, the cleaning component is in the inward position.

[0046] The advantages of this design are: because the cleaning component has an inward and outward position relative to the machine body, the installation position of the cleaning component relative to the machine body can be adjusted. This not only ensures the cleaning effect within the normal cleaning area, but also enables edge cleaning within the working area. Therefore, the cleaning component can better meet the needs of various cleaning conditions and achieve a better all-round cleaning effect on the ground.

[0047] The present invention further provides a cleaning system, which includes the cleaning equipment and base station described in the above example. The base station includes a base and a cleaning tank for containing cleaning fluid. The cleaning tank is provided with a heating device for heating the cleaning fluid.

[0048] The beneficial effects of this design are as follows: Because a heating device is installed inside the washing tank, the distance between the heating device and the washing tank can be shortened, thereby reducing heat loss during the transportation of the cleaning fluid. This improves the heating efficiency of the cleaning fluid, contributing to energy conservation and emission reduction. Simultaneously, the phase change material can absorb and store heat during the cleaning process, transferring the stored heat to the cloth during cleaning operations. This replenishes the cloth's heat, extending the time for mopping with hot water and improving the cleaning effect.

[0049] In one example of the cleaning system of this utility model, the base is provided with a channel for the cleaning equipment to enter and exit, the cleaning tank includes a front tank part provided on the side near the channel opening and a rear tank part provided on the side away from the channel opening, the bottom wall height of the front tank part is lower than the bottom wall height of the rear tank part, and the heating device is provided in the front tank part.

[0050] The beneficial effects of this setup are: by making the bottom wall height of the front tank lower than that of the rear tank, and by placing the heating device in the front tank, more cleaning fluid can be stored in the front tank, thereby improving the heating effect and efficiency of the heating device on the cleaning fluid.

[0051] In one example of the cleaning system of this utility model, the base station includes a liquid supply pipeline, and a water spray hole is provided in the cleaning tank. The water spray hole is connected to the liquid supply pipeline. The water spray direction of the water spray hole is inclined to the front tank so that the water drop point of the water spray hole is located in the front tank.

[0052] The beneficial effects of this design are: when the cleaning tank is accidentally bumped or moved, the water spray holes can spray water onto the front tank in time to cool it down and reduce the risk of burns to surrounding objects or people.

[0053] In one example of the cleaning system of this utility model, the base station includes a liquid supply pipeline connected to the cleaning tank, and an instant heating component is provided on the liquid supply pipeline to heat the cleaning liquid. The outlet of the instant heating component is connected to the cleaning tank.

[0054] The beneficial effects of this setup are as follows: the cleaning fluid in the cleaning tank is preheated by the instant heating component and then heated by the heating device. This allows the cleaning fluid in the cleaning tank to be heated twice, which improves the heating efficiency of the heating device and reduces the heating temperature of the cleaning fluid by the instant heating component. This reduces the probability of scale buildup inside the instant heating component due to excessively high temperatures and lowers the maintenance frequency of the instant heating component.

[0078] Please refer to Figures 1 to 18. This utility model discloses a cleaning component 10, a cleaning device 20, and a cleaning system 30. The cleaning component 10 provides a phase change material 13 on a cloth mounting bracket 11 and / or a cloth 12, and makes the phase change material 13 thermally connected to the cloth 12. In this way, during the cleaning process of the cloth 12, the phase change material 13 can absorb and store heat from the heat source, and release heat to heat the cloth 12 when the cloth 12 is cleaning. This enables the cloth 12 to be used for hot mopping, which is beneficial for removing stubborn stains, oil stains, etc. on the floor, thus improving the cleaning effect of the cleaning component 10.

[0079] Please refer to Figures 1 and 9. The cleaning device 20 provided by this utility model includes a body 21 and a cleaning component 10.

[0080] The interior of the body 21 has a storage space to accommodate various components of the cleaning equipment 20. The shape of the body 21 can be arbitrary, such as circular, elliptical, or D-shaped. The cleaning equipment 20 may also include a walking assembly conventionally provided on existing cleaning equipment 20s. The walking assembly is located below the body 21 to drive the cleaning equipment 20 to achieve self-movement. The specific structure of the walking assembly and the connection structure between the walking assembly and the body 21 can be referred to the relevant structural descriptions in existing cleaning equipment 20s, and will not be repeated here.

[0081] The cleaning component 10 can be detachably connected to the main body 21. The detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, etc. The cleaning component 10 is configured for wet mopping. The main body 21 is equipped with a water replenishment mechanism (not shown in the figure). The water outlet of the water replenishment mechanism is connected to the mop 12 to provide liquid to the mop 12 on the cleaning component 10. The liquid can be cleaning fluid or ordinary tap water, depending on the wet mopping requirements of the cleaning equipment 20.

[0082] Please refer to Figures 10 and 11. The cleaning device 20 is equipped with a base station 31. The base station 31 has a cleaning structure, which can be an existing cleaning tank structure or any other structure capable of containing cleaning fluid and cleaning the cloth 12. During the cleaning operation, the cleaning device 20 can return to the base station 31 multiple times to clean the cleaning component 10. The base station 31 is equipped with a heating device that can heat the cleaning fluid contained in the cleaning structure to achieve thermal cleaning of the cleaning component 10, thereby enhancing the cleaning effect of the cleaning component 10.

[0083] Please refer to Figures 1, 2, 3, and 9. In one embodiment of this utility model, the cleaning component 10 includes a cloth mounting bracket 11 and a cloth 12. The cloth mounting bracket 11 is installed below the body 21, and the cloth 12 is installed on the cloth mounting bracket 11. The cloth mounting bracket 11 and the cloth 12 can be detachably connected or fixedly connected. The cloth 12 can be a round cloth, a rectangular cloth, or a polygonal cloth, etc. In this embodiment, for ease of description, the cloth 12 is a round cloth. A round cloth means that the cleaning surface between the cloth 12 and the ground has a circular outline.

[0084] It should be noted that the number of cleaning components 10 on the cleaning device 20 can be one or more sets, depending on the cleaning area and cleaning efficiency requirements of the cleaning device 20. In this embodiment, please refer to Figures 9 and 11. The cleaning device 20 is equipped with two sets of cleaning components 10, which are symmetrically installed on the bottom of the body 21 to perform cleaning operations on the ground during the movement of the cleaning device 20.

[0085] Please refer to Figures 16 to 18. In one example of the cleaning device 20 of this utility model, the cleaning device 20 includes two cleaning components 10. Both cleaning components 10 are movably connected to the machine body 21. "Movably connected to the machine body 21" means that the cleaning component 10 can rotate around a pivot axis to achieve rotary cleaning. Both cleaning components 10 can be oscillatingly connected to the machine body, or one of the cleaning components 10 can be oscillatingly connected to the machine body. "Oscillatingly connected to the machine body" means that the pivot axis of the cleaning component 10 is adjustable in planar position relative to the machine body 21, so that the cleaning component 10 has both an inward-retracted position and an outward-swinging position relative to the machine body 21. The traveling direction of the machine body 21 is defined as the length direction of the machine body 21 (as shown by the X-axis in Figure 17), and the direction perpendicular to the traveling direction of the machine body 21 is defined as the width direction of the machine body 21 (as shown by the Y-axis in Figure 17). When the cleaning component 10 is in the outward swing position, relative to the inward retraction position, the rotation axis of the cleaning component 10 moves outward along the width direction of the machine body 21, thereby enabling the cleaning device 20 to perform edge cleaning operations. When the cleaning component 10 is in the inward retraction position, the rotation axis of the cleaning component 10 moves inward along the width direction of the machine body 21, and the two cleaning components 10 move closer to each other to ensure effective cleaning within the working area between them. It should be noted that the specific structure enabling the cleaning component 10 and the machine body 21 to achieve the inward and outward swing positions can be found in the relevant structural descriptions of existing cleaning devices 10, and will not be elaborated upon here.

[0086] When the cleaning component 10's cloth 12 needs to absorb heat from the heat source, the cleaning component 10 is in a retracted position. This reduces the storage space occupied by the cleaning device 20 during the cleaning process of the cloth 12, making it easier for the cleaning device 20 to enter and exit the base station 31.

[0087] Since the cleaning component 10 has an inward and outward position relative to the body 21, this setting allows for adjustment of the installation position of the cleaning component 10 relative to the body 21. This not only ensures the cleaning effect in the area between the two cleaning components 10, but also enables edge cleaning in the work area. Therefore, the cleaning component 10 can better meet the needs of various cleaning conditions and improve the all-round cleaning effect of the ground.

[0088] Please refer to Figures 3, 4, and 8. The cloth mounting bracket 11 includes a phase change material 13, which is thermally connected to the cloth 12. The phase change material 13 can be a solid-liquid phase change material, meaning it can transform between a solid and a liquid state within a certain temperature range. When the phase change material 13 changes from a solid to a liquid state, it absorbs heat; when it changes from a liquid to a solid state, it releases heat. The phase change material 13 can also be a solid-solid phase change material, meaning it undergoes a phase change between two solid states. When the phase change material 13 changes from a first solid state to a second solid state, it absorbs heat; when it changes from a second solid state to a first solid state, it releases heat. The change in state of the phase change material 13 allows the cloth mounting bracket 11 to switch between heat absorption and release.

[0089] It should be noted that when the phase change material 13 is a solid-liquid phase change material, it needs to be installed in a sealed cavity. However, when the phase change material 13 is a solid-solid phase change material, it does not need to be installed in a sealed cavity.

[0090] Under the condition of meeting the thermal conductivity requirements between the phase change material 13 and the wiping cloth 12, the phase change material 13 can be disposed on the side of the wiping cloth mounting bracket 11 facing the wiping cloth 12, so that the phase change material 13 and the wiping cloth 12 can directly contact each other for heat conduction, as shown in Figure 8. Alternatively, the phase change material 13 can be disposed within the sealed cavity of the wiping cloth mounting bracket 11, and indirect heat conduction between the phase change material 13 and the wiping cloth 12 can be achieved through other heat-conducting components, as shown in Figure 3. In another embodiment, the wiping cloth 12 can also include the phase change material 13, that is, the phase change material 13 is disposed within the wiping cloth 12, as shown in Figure 4. In other embodiments, the wiping cloth mounting bracket 11 can also include a portion of the phase change material 13, and the wiping cloth 12 can also include a portion of the phase change material 13, that is, the phase change material 13 is partially disposed within the wiping cloth mounting bracket 11 and partially disposed within the wiping cloth 12. In actual design and production, the specific placement of the phase change material 13 also needs to consider various factors such as the heat absorption requirements of the wiping cloth 12, production process conditions, and production costs.

[0091] When the cleaning cloth 12 is not in a cleaning state, the phase change material 13 absorbs heat from the heat source to store the heat; when the cleaning cloth 12 is in a cleaning state, the phase change material 13 releases heat to the cleaning cloth 12 to conduct heat through the cleaning cloth 12, thereby achieving hot mopping. In this embodiment, the heat source can be a cleaning liquid with a certain temperature, a heating element for heating the cleaning liquid, or a combination of the cleaning liquid and the heating element. The non-cleaning operation includes at least a portion of the cleaning process, drying process, and soaking / heating process of the cleaning cloth 12. For example, in one embodiment, the non-cleaning operation can be any single process of the cleaning process, drying process, or hot water soaking process of the cleaning cloth 12. In another embodiment, the non-cleaning operation can also be a combination of two or three of the cleaning process, drying process, and soaking / heating process of the cleaning cloth 12.

[0092] By incorporating phase change material 13, the cleaning component 10 can heat the cloth 12 during non-cleaning operations, achieving hot mopping and thus improving the cleaning effect. Simultaneously, due to the high energy density of phase change material 13, it can absorb or release a large amount of heat during phase change and store a significant amount of thermal energy in a relatively small volume or mass, saving installation space and reducing the overall weight of the cleaning component 10. Furthermore, since phase change material 13 only absorbs heat during at least a portion of the cleaning, drying, and soaking / heating processes of the cloth 12, this embodiment eliminates the need for an additional heat source compared to existing technologies that use an active heating device on the cleaning equipment body. This simplifies the internal circuit design and structure of the cleaning equipment 20. Therefore, the overall electrical safety of the cleaning equipment 20 in this embodiment is enhanced, reducing the probability of circuit failures during use.

[0093] In one example of the cleaning component 10 of this utility model, the heat source includes a heating device 32. The heating device 32 can be disposed inside the cleaning tank 312 of the base station 31 or outside the base station 31. The key is to heat the cloth 12 when it is not in a cleaning operation, allowing the phase change material 13 to absorb heat. In another embodiment, the heat source can also be hot water, which can be heated cleaning fluid located in the cleaning tank 312. That is, when the cloth 12 comes into contact with the cleaning fluid in the cleaning tank 312, the phase change material 13 can absorb the heat from the cleaning fluid. The hot water can also be a liquid contained in a container outside the base station 31. This liquid can be clean water or cleaning fluid. When the cloth 12 is immersed in the hot water in the container and heated, the phase change material 13 can also absorb the heat from the hot water. In other embodiments, the heat source can also be a combination of heating device 32 and hot water. For example, heating device 32 is installed inside cleaning tank 312, and cleaning tank 312 is also filled with heated cleaning liquid (i.e. hot water). When the rag 12 enters the cleaning tank 312, the rag 12 can contact the heating device 32 and the cleaning liquid at the same time, so that the phase change material 13 can absorb the heat from the heating device 32 and the heat from the cleaning liquid at the same time.

[0094] By setting the heat source to heating device 32 and / or hot water, the heating efficiency of the rag 12 can be improved, which in turn can improve the heat absorption efficiency of phase change material 13, thereby improving the cleaning efficiency of cleaning component 10.

[0095] Considering the convenience of connecting the cleaning component 10 and the drive component 22 of the cleaning device 20, optionally, referring to Figures 2, 3, and 9, in one example of the cleaning component 10 of this utility model, the cloth mounting bracket 11 is provided with a connecting part 14 on the side opposite to the cloth 12, which can be detachably connected to the drive component 22. Specifically, the connecting part 14 is connected to the drive shaft of the drive component 22 so that the cleaning component 10 can be driven to perform cleaning operations when the drive component 22 is running. The connecting part 14 can be a protruding column structure or a groove structure, as long as it can be adapted to the drive shaft of the drive component 22. The connecting part 14 includes a magnetic attraction structure 141 that can be attracted to the drive shaft of the drive component 22. The magnetic attraction structure 141 can take many forms. In this embodiment, the magnetic attraction structure 141 can be a magnet, that is, the connecting part 14 includes a magnet. In this case, the drive shaft is a ferromagnetic material, and the connecting part 14 and the drive shaft are magnetically connected to achieve an axial fixed connection between the connecting part 14 and the drive shaft. In another embodiment, the magnetic attraction structure 141 can also be a ferromagnetic material, that is, the connecting part 14 includes a ferromagnetic material. In this case, the drive shaft is a magnet, and a magnetic connection can also be achieved between the connecting part 14 and the drive shaft. In other embodiments, the magnetic attraction structure 141 can be a magnet, that is, the connecting part 14 includes a magnet. In this case, the drive shaft is also a magnet, and the magnets of the connecting part 14 and the drive shaft have opposite polarities. This also achieves a magnetic connection between the connecting part 14 and the drive shaft.

[0096] By setting up the magnetic attraction structure 141, no other tools are needed when installing the connecting part 14 and the drive assembly 22, so the installation is very convenient. At the same time, when removing the connecting part 14 from the drive assembly 22, a pulling force greater than the magnetic attraction force can be applied directly to the side of the connecting part 14, so the disassembly process is also relatively convenient.

[0097] In another example of the cleaning component 10 of this utility model, the connecting part 14 includes a snap-fit ​​structure (not shown in the figure) that can engage with the driving component 22. The snap-fit ​​structure can take various forms. For example, the snap-fit ​​structure can be a conical hole structure, in which case the drive shaft of the driving component 22 is a frustum structure. The frustum engages with the conical hole in a conical snap-fit ​​connection, thereby achieving the snap-fit ​​connection between the connecting part 14 and the driving component 22. Alternatively, the snap-fit ​​structure can be multiple wedge-shaped blocks disposed on the outer periphery of the connecting part 14. In this case, the drive shaft of the driving component 22 has a groove structure, the connecting part 14 is inserted into the groove, and the multiple wedge-shaped blocks abut against the sidewalls of the groove along the circumferential direction of the drive shaft, forming a frictional abutment, thereby achieving the snap-fit ​​connection between the connecting part 14 and the driving component 22. By providing a snap-fit ​​structure on the connecting part 14, the assembly and disassembly of the connecting part 14 and the driving component 22 can also be facilitated. To reduce the impact force generated when the cleaning component 10 comes into contact with surrounding obstacles during cleaning operations, please refer to Figures 2 and 3. In one example of the cleaning component 10 of this utility model, a buffer portion 111 is provided on the outer periphery of the cloth mounting bracket 11 to absorb the impact force from the edge of the cleaning component 10. The buffer portion 111 can be a ring-shaped structure made of a plastic or silicone material with a certain degree of flexibility. When the ring-shaped structure is impacted, it can absorb the impact force through its own elastic-plastic deformation, thus playing a buffering role. The buffer portion 111 can also be an elastic structure provided on the outer periphery of the cloth mounting bracket 11, such as a combination of a spring and a baffle. When the baffle is impacted, the spring absorbs the impact force through its expansion and contraction deformation, thereby playing a buffering role. By providing a buffer portion 111 on the outer periphery of the cloth mounting bracket 11, the impact of external collision forces on the cleaning component 10 itself can be effectively mitigated, reducing the wear and tear on the cloth mounting bracket 11 and improving the service life of the cleaning component 10. On the other hand, the buffer section 111 can also reduce the scratching and impact on furniture and walls during the cleaning operation of the rag mounting bracket 11, thereby reducing the degree of damage to furniture and walls, and also reducing the collision noise generated during the cleaning operation.

[0098] Referring to Figures 2 and 3, in one example of the cleaning component 10 of this utility model, the buffer part 111 includes a soft rubber structure 112, which has multiple deformable hollow areas 1121. The material of the soft rubber structure 112 can be silicone, rubber, etc. The soft rubber structure 112 can be a ring structure that surrounds the entire circumference of the cloth mounting bracket 11, or it can be a block structure with multiple intervals. The deformable hollow areas 1121 on the soft rubber structure 112 can be various shapes such as round holes, square holes, or polygonal holes. Optionally, in order to obtain a uniform buffering effect in the circumferential direction of the cloth mounting bracket 11, in this embodiment, the soft rubber structure 112 is a ring structure coaxially arranged with the cloth mounting bracket 11, and multiple deformable hollow areas 1121 are arrayed on the ring structure. By setting a soft rubber structure 112 and providing multiple deformable hollow areas 1121 on the soft rubber structure 112, the soft rubber structure 112 can be thermoformed onto the outer periphery of the cloth mounting bracket 11, making molding and installation convenient and eliminating the need for additional mechanical connections. Simultaneously, the combination of the soft rubber structure 112 and the deformable hollow areas 1121 provides a better cushioning effect on the outer periphery of the cloth mounting bracket 11.

[0099] Considering that commonly used phase change materials 13 are generally solid-liquid phase change materials, leakage of the phase change material 13 needs to be considered when it changes from solid to liquid during the phase change process. Therefore, optionally, referring to Figure 3, in one example of the cleaning component 10 of this utility model, the cloth mounting bracket 11 is provided with a sealing cavity 113, which is filled with the phase change material 13. The sealing cavity 113 can be an integral annular cavity structure surrounding the cloth mounting bracket 11, or it can be a multi-interval partial cavity structure. The specific structure of the sealing cavity 113 needs to be determined according to the structural shape of the cloth mounting bracket 11. The phase change material 13 can fill the entire sealing cavity 113 or partially fill it. There are various ways to form the sealing cavity 113. For example, the sealing cavity 113 can be formed by integral injection molding of the cloth mounting bracket 11, or it can be formed by assembling the cloth mounting bracket 11 into upper and lower parts. In this embodiment, no specific limitation is made. It should be noted that the side of the sealed cavity 113 facing the cloth 12 needs to have good thermal conductivity so that the heat of the phase change material 13 inside the sealed cavity 113 can be effectively conducted to the cloth 12, thereby heating the cloth 12. Alternatively, in other embodiments, when the phase change material 13 is a solid-solid phase change material, it can also be placed inside the sealed cavity 113. By setting the sealed cavity 113 on the cloth mounting bracket 11 and filling the sealed cavity 113 with the phase change material 13, this arrangement not only prevents the probability of leakage of the phase change material 13 during the phase change process, ensuring the heat storage performance of the phase change material 13, but also reduces the influence of external factors (such as air and moisture) during the phase change process, thereby maintaining the stability of the performance of the phase change material 13.

[0100] There are various ways to fill the sealed cavity 113 with the phase change material 13. Optionally, in one example of the cleaning component 10 of this utility model, as shown in Figure 3, the cloth mounting bracket 11 is provided with an opening 114, which communicates with the sealed cavity 113. Liquid phase change material 13 is injected into the sealed cavity 113 through the opening 114. The opening 114 can be provided at multiple locations such as the upper surface, lower surface, or side of the cloth mounting bracket 11. There can be one or multiple openings 114. When the sealed cavity 113 is an integral cavity structure, only one opening 114 is required. However, when the sealed cavity 113 is a multi-cavity structure that is not interconnected, at least one opening 114 needs to be provided on each cavity structure. The opening 114 can be any shape that meets the filling requirements of liquid phase change material 13, such as a round hole, a square hole, or an irregularly shaped hole. Preferably, in this embodiment, the sealing cavity 113 is an integral cavity structure, and the cloth mounting bracket 11 has an opening 114 communicating with the sealing cavity 113 on the side opposite to the cloth 12. A sealing cover 1141 is fitted over the opening 114. The sealing cover 1141 can be detachably fitted over the opening 114, for example, by sealing a threaded connection. Alternatively, it can be non-detachably fitted over the opening 114, for example, by adhesive bonding or heat fusion connection. By providing an opening 114 communicating with the sealing cavity 113 on the cloth mounting bracket 11, liquid phase change material 13 can be injected into the sealing cavity 113 through the opening 114, thus allowing the sealing cavity 113 to be made into an integral structure, making it easier to ensure the sealing performance of the sealing cavity 113. At the same time, the usage status of the phase change material in the sealing cavity 113 can be easily viewed through the opening 114, so as to understand the changes in the heat storage performance of the phase change material 13 in a timely manner.

[0101] Referring to Figure 3, in one example of the cleaning component 10 of this utility model, the cloth mounting bracket 11 includes an upper cover 115 and a lower cover 116, which are sealed together to form a sealed cavity 113. The lower cover 116 is disposed near the cloth 12 and connected to the cloth 12. The upper cover 115 and the lower cover 116 can be sealed together by fasteners such as bolts and sealing elements. Alternatively, the upper cover 115 and the lower cover 116 can be sealed together by hot-melt adhesive. The forming structure of the sealed cavity 113 is not limited; for example, the upper cover 115 may have a groove, and the lower cover 116 may seal the groove opening to form the sealed cavity 113; or the lower cover 116 may have a groove, and the upper cover 115 may seal the groove opening to form the sealed cavity 113, etc. By setting up an upper cover 115 and a lower cover 116, which are connected to form a sealed cavity 113, this arrangement facilitates the split design of the cloth mounting bracket 11, makes injection molding easier, and helps reduce processing costs. Furthermore, before the upper cover 115 and lower cover 116 are closed, the solid phase change material 13 can be pre-installed in the sealed cavity 113. Then, the connection between the upper cover 115 and lower cover 116 achieves the seal of the sealed cavity 113, thus facilitating the installation of the solid phase change material 13 within the sealed cavity 113.

[0102] Although there are various ways to connect the upper cover 115 and the lower cover 116, considering the assembly efficiency of the cloth mounting bracket 11, preferably, in one example of the cleaning component 10 of this utility model (see Figure 3), the cloth mounting bracket 11 also includes hot melt adhesive 118, and the upper cover 115 and the lower cover 116 are heat-fused together by hot melt adhesive 118. Hot melt adhesive 118 can be of various types, such as EVA hot melt adhesive and PUR hot melt adhesive, and the type needs to be determined based on the material and connection performance requirements of the upper cover 115 and the lower cover 116 in actual use. Hot melt adhesive 118 is disposed at the joint between the upper cover 115 and the lower cover 116, that is, both sides of the hot melt adhesive 118 are in contact with the upper cover 115 and the lower cover 116 respectively. When the upper cover 115 and the lower cover 116 need to be connected, the hot melt adhesive 118 is heated to melt it. Simultaneously, mating pressure is applied between the upper cover 115 and the lower cover 116 until the hot melt adhesive 118 cools and solidifies again, thus achieving a sealed and fixed connection between the upper cover 115 and the lower cover 116. By using hot melt adhesive 118 to form a molten connection between the upper cover 115 and the lower cover 116, this method offers higher connection efficiency in mass production compared to connection methods using bolts or other fasteners, and also makes it easier to ensure sealing performance.

[0103] To further improve the thermal conductivity between the phase change material 13 and the cleaning cloth 12, optionally, referring to Figure 3, in one example of the cleaning component 10 of this utility model, the lower cover 116 is thermally connected to the cleaning cloth 12, that is, the cleaning cloth 12 is installed on the lower cover 116 and thermally connected to the side surface of the lower cover 116 opposite to the upper cover 115. The thermal conductivity of the lower cover 116 is greater than that of the upper cover 115. For example, the lower cover 116 can be made of metal and the upper cover 115 can be made of plastic, thus achieving a higher thermal conductivity for the lower cover 116 than for the upper cover 115. Alternatively, the upper cover 115 can be made of ordinary plastic materials with low thermal conductivity, such as polyethylene or polypropylene, while the lower cover 116 can be made of modified plastic material with high thermal conductivity due to the addition of metal materials, which also results in a higher thermal conductivity for the lower cover 116 than for the upper cover 115. By making the thermal conductivity of the lower cover 116 greater than that of the upper cover 115, this configuration allows for several advantages. First, the heat stored in the phase change material 13 can be quickly conducted to the cloth 12 through the lower cover 116, heating the cloth 12 and improving its heating efficiency and effect. Second, it reduces heat transfer from the phase change material 13 within the sealed cavity 113 to the outside through the upper cover 115, thereby reducing heat loss from the phase change material 13 and further enhancing its heating effect on the cloth 12.

[0104] To further reduce heat transfer from the phase change material 13 to the outside through the upper cover 115, preferably, in one example of the cleaning assembly 10 of this utility model, referring to Figure 3, an adhesive layer 1151 is provided on the side of the upper cover 115 facing away from the lower cover 116. The adhesive layer 1151 can be applied to the entire upper surface of the upper cover 115, or it can be applied to only a portion of the upper surface of the upper cover 115. By providing the adhesive layer 1151 on the upper cover 115, and since the adhesive layer 1151 has a low thermal conductivity, it can cover and shield the exposed surface of the upper cover 115, thereby reducing the heat exchange rate between the upper cover 115 and the surrounding air, and thus reducing heat transfer from the phase change material 13 to the outside through the upper cover 115. Specifically, in this embodiment, the upper surface of the upper cover 115 includes a first ring portion 1152 and a second ring portion 1153 coaxially arranged, both protruding towards the side opposite to the lower cover 116. The first ring portion 1152 is located at the outer periphery of the upper cover 115, and the second ring portion 1153 is disposed between the connecting portion 14 and the first ring portion 1152, with the second ring portion 1153 positioned closer to the connecting portion 14. An adhesive layer 1151 is applied to the surface of the second ring portion 1153 facing away from the lower cover 116. This design not only reduces the heat transfer from the phase change material 13 to the outside through the upper cover 115, but also, since the second ring portion 1153 is close to the connecting portion 14, when the cleaning component 10 is installed, the second ring portion 1153 will abut against the end face of the drive shaft of the drive component. Therefore, when the cleaning component 10 needs to be disassembled, the adhesive layer 1151 can also increase the friction between the end face of the drive shaft and the cloth mounting bracket 11, thereby facilitating the disassembly of the cleaning component 10.

[0105] Referring to Figure 3, in one example of the cleaning component 10 of this utility model, the lower cover 116 includes a heat-conducting rib 1161, which extends at least partially into the interior of the sealing cavity 113. The material of the heat-conducting rib 1161 can be the same as that of the lower cover 116, for example, both being metals with good thermal conductivity, or both being plastics with good thermal conductivity. The material of the heat-conducting component 322 can also be different from that of the lower cover 116; for example, the heat-conducting rib 1161 can be made of metal, while the lower cover 116 is made of plastic. The heat-conducting rib 1161 can be integrally formed with the lower cover 116, or it can be assembled separately, depending on meeting the thermal connection requirements between the heat-conducting rib 1161 and the lower cover 116. The shape of the heat-conducting rib 1161 within the sealing cavity 113 can be a structure of multiple spaced triangular ribs, an integral annular thin-walled structure, or a structure of multiple spaced elongated ribs, etc. By providing heat-conducting ribs 1161 on the lower cover 116 and extending at least partially into the interior of the sealing cavity 113, the contact area between the phase change material 13 and the lower cover 116 can be increased, thereby increasing the heat conduction efficiency between the phase change material 13 and the lower cover 116, and ultimately improving the heat transfer efficiency of the phase change material 13 to the rag 12, so as to ensure the hot mopping effect of the rag 12.

[0106] Referring to Figures 4 and 5, in one example of the cleaning component 10 of this utility model, the cleaning cloth 12 includes a fabric layer 121, an absorbent layer 122, and an adhesive layer 123 connected sequentially from bottom to top. The fabric layer 121, absorbent layer 122, and adhesive layer 123 can be connected by adhesive bonding, sewing, or other methods. Optionally, in this embodiment, the fabric layer 121, absorbent layer 122, and adhesive layer 123 are connected by sewing to form the cleaning cloth 12. Sewing is a low-cost and simple and quick operation. The fabric layer 121, absorbent layer 122, and adhesive layer 123 are coaxially arranged disc-shaped structures, and the outer diameters of the three layers are basically the same. A mounting hole 124 for connecting to the cleaning cloth mounting bracket 11 is provided in the central area of ​​the cleaning cloth 12. The mounting hole 124 penetrates the fabric layer 121, absorbent layer 122, and adhesive layer 123 along the thickness direction of the cleaning cloth 12. The fabric layer 121 is used for mopping and absorbing stains. The fabric layer 121 can be any fabric suitable for mopping, such as cotton, fiber cloth, or non-woven fabric. The absorbent layer 122 can be a sponge or a highly absorbent cotton cloth to store some moisture in the cloth 12, enabling wet mopping. Referring to Figures 4 and 8, the cloth mounting bracket 11 has an adhesive part 15 on the side facing the cloth 12. The adhesive layer 123 is used to bond to the adhesive part 15. The adhesive part 15 can be an adhesive, and the adhesive layer 123 is bonded to the adhesive part 15 to achieve a fixed connection between the cloth mounting bracket 11 and the cloth 12. The adhesive part 15 can also be an adhesive fastener, and the adhesive layer 123 can be a bristle fabric that can be bonded to the adhesive fastener. The adhesive layer 123 is bonded to the adhesive fastener to achieve a fixed connection between the cloth mounting bracket 11 and the cloth 12.

[0107] Referring to Figures 4 and 5, the phase change material 13 is disposed between the fabric layer 121 and the absorbent layer 122. The phase change material 13 can be sandwiched between the fabric layer 121 and the absorbent layer 122, or it can be bonded to either the fabric layer 121 or the absorbent layer 122. In another embodiment, the phase change material 13 can also be disposed between the absorbent layer 122 and the adhesive layer 123. In other embodiments, the phase change material 13 can be partially disposed between the fabric layer 121 and the absorbent layer 122, and partially disposed between the absorbent layer 122 and the adhesive layer 123. It should be noted that the area of ​​the phase change material 13 on the cloth 12 needs to consider not only the heat storage requirements of the phase change material 13, but also the water absorption requirements of the absorbent layer 122. That is, the phase change material 13 cannot completely cover or block the absorbent surface of the absorbent layer 122; a portion of the area needs to be reserved for the normal water absorption of the absorbent layer 122. The specific coverage area of ​​the phase change material 13 on the water-absorbing layer 122 needs to be calculated based on the actual water absorption of the cloth 12 and the heat storage requirements of the phase change material 13.

[0108] By placing the phase change material 13 between the fabric layer 121 and the absorbent layer 122 and / or between the absorbent layer 122 and the adhesive layer 123, the phase change material 13 can be fully immersed in the cleaning solution when the cloth 12 is being washed. This increases the contact area between the phase change material 13 and the cleaning solution, thereby improving the heat storage efficiency of the phase change material 13. Simultaneously, the heat conduction path between the phase change material 13 and the fabric layer 121 is shorter during cleaning, thus reducing heat loss during the heat conduction process from the phase change material 13 to the fabric layer 121. This further enhances the heat conduction effect of the phase change material 13 on the fabric layer 121, extending the hot mopping time of the fabric layer 121 and further improving the cleaning effect of the cloth 12.

[0109] Please refer to Figures 4 and 5. In one example of the cleaning component 10 of this utility model, the sum of the areas of the upper and lower surfaces of the absorbent layer 122 is S1. The upper surface of the absorbent layer 122 refers to the surface of the absorbent layer 122 facing the adhesive layer 123, and the lower surface of the absorbent layer 122 refers to the surface of the absorbent layer 122 facing the fabric layer 121. The area S2 of the absorbent layer 122 covered by the phase change material 13 is less than or equal to 1 / 2 of S1. The phase change material 13 can be disposed only on the upper surface of the absorbent layer 122, or only on the lower surface of the absorbent layer 122, or the phase change material 13 can be disposed alternately on the upper and lower surfaces, as long as it ensures that the area S2 of the absorbent layer 122 covered by the phase change material 13 is less than or equal to 1 / 2 of S1.

[0110] When the phase change material 13 is disposed on the upper surface of the water-absorbing layer 122, the phase change material 13 will cover the upper surface of the water-absorbing layer 122. When the phase change material 13 is disposed on the lower surface of the water-absorbing layer 122, the phase change material 13 will cover the lower surface of the water-absorbing layer 122. The larger the area of ​​the water-absorbing layer 122 covered by the phase change material 13, the weaker the water absorption performance of the water-absorbing layer 122, but the better the heat storage performance of the phase change material 13. Conversely, the smaller the area of ​​the water-absorbing layer 122 covered by the phase change material 13, the stronger the water absorption performance of the water-absorbing layer 122, but the worse the heat storage performance of the phase change material 13. In this embodiment, the area S2 of the water-absorbing layer 122 covered by the phase change material 13 is set to be less than or equal to 1 / 2 of S1. Within this range, the water absorption performance requirements of the water-absorbing layer 122 can be met to ensure the wet mopping effect of the rag 12, while also taking into account the heat storage requirements of the phase change material 13 to ensure the hot mopping effect of the rag 12.

[0111] When the phase change material 13 is a solid-liquid phase change material, in order to prevent leakage of the phase change material 13 in the liquid state, optionally, in one example of the cleaning component 10 of this utility model, a sealing interlayer (not shown in the figure) is provided between the fabric layer 121 and the absorbent layer 122, and the phase change material 13 is filled in the sealing interlayer. The sealing interlayer can be bonded to the absorbent layer 122 or the fabric layer 121, or it can be fixed between the fabric layer 121 and the absorbent layer 122 by sewing the absorbent layer 122 and the fabric layer 121 together. The shape of the sealing interlayer is related to the distribution position of the phase change material 13. When the phase change material 13 is spaced between the fabric layer 121 and the absorbent layer 122, the sealing interlayer consists of multiple spaced interlayer units, and each interlayer unit is filled with the phase change material 13. When the phase change material 13 covers the entire lower surface of the absorbent layer 122, the shape of the sealing interlayer is basically the same as the shape of the absorbent layer 122, so that the phase change material 13 is filled in the sealing interlayer 16, and the phase change material 13 covers the entire lower surface of the absorbent layer 122.

[0112] In another embodiment, a sealing interlayer can be provided between the absorbent layer 122 and the adhesive layer 123, and the sealing interlayer is filled with a phase change material 13. In this case, the phase change material 13 is disposed on the upper surface of the absorbent layer 122. In other embodiments, a sealing interlayer can be provided between the absorbent layer 122 and the fabric layer 121, and also between the absorbent layer 122 and the adhesive layer 123. This allows the phase change material 13 to be disposed on both the upper and lower surfaces of the absorbent layer 122. It should be noted that when the phase change material 13 is a solid-solid phase change material, the phase change material 13 can also be disposed within the sealing interlayer. By providing a sealing interlayer, not only can the probability of leakage during the phase change process of the phase change material 13 be reduced, but the installation and fixation of the phase change material 13 on the cloth 12 can also be facilitated, reducing the difficulty of the installation process of the phase change material 13 on the cloth 12.

[0113] Optionally, in one example of the cleaning component 10 of this utility model, referring to Figure 6, the upper surface of the absorbent layer 122 is provided with a microcapsule layer 17, which contains multiple microcapsules filled with phase change material 13. The size and number of microcapsules in the microcapsule layer 17 need to be determined based on various factors such as the material properties of the phase change material 13 or the difficulty of filling. The microcapsule layer 17 can be coated onto the upper surface of the absorbent layer 122 using coating technology, or it can be bonded to the upper surface of the absorbent layer 122 using adhesives. Preferably, in this embodiment, the microcapsule layer 17 is coated onto the upper surface of the absorbent layer 122. This method can achieve a relatively uniform distribution of microcapsules. The microcapsule layer 17 can cover the entire upper surface of the absorbent layer 122, or it can be multiple microcapsule layers 17 spaced apart on the upper surface of the absorbent layer 122, depending on meeting the heat storage requirements of the phase change material 13 and the water absorption performance of the absorbent layer 122.

[0114] In another embodiment, the lower surface of the absorbent layer 122 may be provided with a microcapsule layer 17. In other embodiments, the upper surface of the absorbent layer 122 may be provided with a microcapsule layer 17, and the lower surface of the absorbent layer 122 may also be provided with a microcapsule layer 17. By providing a microcapsule layer 17 on the absorbent layer 122 and filling the microcapsules with phase change material 13, not only can the probability of leakage of the phase change material 13 during the phase change process be reduced, but the structure of the microcapsules also makes it less likely for the phase change material 13 to overflow from the seam openings of the cloth 12, which is more conducive to retaining the phase change material 13 inside the cloth 12 and reducing the loss of the phase change material 13 during use. At the same time, under the same coating area, the microcapsule structure can also increase the contact area between the phase change material 13 and the cleaning liquid, thereby improving the heat storage efficiency of the phase change material 13.

[0115] Referring to Figures 5 and 6, in one example of the cleaning component 10 of this utility model, the upper surface of the absorbent layer 122 is coated with a plurality of spaced-apart first microcapsule layers 171, and the lower surface of the absorbent layer 122 is coated with a plurality of spaced-apart second microcapsule layers 172, with the plurality of first microcapsule layers 171 and the plurality of second microcapsule layers 172 arranged alternately. It should be noted that the alternate arrangement in this embodiment means that the projections of adjacent first microcapsule layers 171 and second microcapsule layers 172 along the thickness direction of the cloth 12 partially overlap, but partially do not overlap. See Figure 6. There are various ways to arrange the multiple first microcapsule layers 171 and multiple second microcapsule layers 172 in an alternating vertical arrangement. In this embodiment, the multiple first microcapsule layers 171 are spaced apart in a fan-shaped structure along the circumferential direction of the absorbent layer 122, and the multiple second microcapsule layers 172 are also spaced apart in a fan-shaped structure along the circumferential direction of the absorbent layer 122. In the circumferential direction of the absorbent layer 122, the first microcapsule layers 171 and second microcapsule layers 172 are arranged in an alternating vertical arrangement. In other embodiments, the multiple first microcapsule layers 171 can also be arranged in multiple annular spaces along the radial direction of the absorbent layer 122, and the multiple second microcapsule layers 172 can also be arranged in multiple annular spaces along the radial direction of the absorbent layer 122. In the radial direction of the absorbent layer 122, the first microcapsule layers 171 and second microcapsule layers 172 are arranged in an alternating vertical arrangement.

[0116] By staggering the arrangement of multiple first microcapsule layers 171 and multiple second microcapsule layers 172, the arrangement can maximize the area of ​​the microcapsule layers 17 on the absorbent layer 122 while ensuring the absorbency of the absorbent layer 122, thereby increasing the amount of phase change material 13 used and ensuring the heat storage performance of the phase change material 13 and the thermal conductivity of the fabric layer 121. On the other hand, since the first microcapsule layer 171 and the second microcapsule layer 172 are staggered, when the mop 12 is replenished with water during mopping, the water flow will enter from the upper surface of the absorbent layer 122, bypass the staggered position of the first microcapsule layer 171 and the second microcapsule layer, and then flow from the lower surface of the absorbent layer 122 to the fabric layer 121. Therefore, the flow path length of the water flow in the absorbent layer 122 can be increased, the residence time of the water flow in the mop 12 can be extended, and the contact time between the water flow and the phase change material 13 can be increased, thereby increasing the outlet temperature of the water flow and thus improving the hot mopping effect of the mop 12.

[0117] Please refer to Figures 7 and 8. In one example of the cleaning component 10 of this utility model, the phase change material 13 is a solid-solid phase change material, and the cloth mounting bracket 11 is at least partially composed of the phase change material 13. The specific type of solid-solid phase change material is not limited, as long as the phase change material 13 can meet the strength and hardness requirements of the cloth mounting bracket 11 during the phase change process. The cloth mounting bracket 11 can be entirely made of the phase change material 13, or only the part of the cloth mounting bracket 11 that contacts the cloth 12 can be made of the phase change material 13, as long as the thermal conductivity requirements between the phase change material 13 and the cloth 12 are met. This arrangement allows for direct contact between the phase change material 13 and the cloth 12, thereby reducing the thermal conductivity path between them and further improving the heating effect of the phase change material 13 on the cloth 12. Simultaneously, there is no need to additionally install the phase change material 13 on the cloth mounting bracket 11, thus reducing the weight of the cloth mounting bracket 11 itself and contributing to its lightweight design.

[0118] Optionally, in one example of the cleaning component 10 of this utility model, where the phase change material 13 is a solid-solid phase change material, the entire cloth mounting frame 11 is injection molded from the phase change material 13. That is, the entire cloth mounting frame 11 is made of phase change material 13. This arrangement allows for a large area and mass of phase change material 13 on the cloth mounting frame 11, thereby increasing the contact area between the phase change material 13 and the cleaning liquid during the cleaning process of the cloth 12, thus improving the heat storage efficiency and energy storage capacity of the phase change material 13. This extends the heat transfer time of the phase change material 13 to the cloth 12 during the cleaning operation, further improving the hot mopping effect of the cloth 12.

[0119] When the phase change material 13 is a solid-solid phase change material, optionally, in one example of the cleaning component 10 of this utility model, referring to Figure 8, the cloth mounting bracket 11 includes a main body 117. The material of the main body 117 can be plastic or metal, specifically to meet the support requirements of the cloth mounting bracket 11. The side of the main body 117 facing the cloth 12 includes the phase change material 13, and the phase change material 13 at least partially abuts against the cloth 12. The phase change material 13 can be integrally heat-fused to the main body 117, or it can be bonded, or it can be fixed by bolts, etc. The phase change material 13 can be a disc-shaped structure adapted to the shape of the cloth 12, or it can be a multi-spaced partial block structure. To obtain a larger area of ​​phase change material 13 and increase the contact area between phase change material 13 and wiping cloth 12, preferably, in this embodiment, the phase change material 13 is a toroidal structure adapted to the shape of wiping cloth 12, that is, the shape of the side of phase change material 13 facing wiping cloth 12 is approximately the same as the shape of wiping cloth 12. The phase change material 13 and wiping cloth 12 can be bonded together by adhesive or by adhesive fastener 16. Optionally, to facilitate the assembly and disassembly of wiping cloth 12 and wiping cloth mounting bracket 11, in this embodiment, adhesive fastener 16 is installed on the side of phase change material 13 facing wiping cloth 12, and the side of wiping cloth 12 facing phase change material 13 is made of bristle fabric. The fixed connection between wiping cloth 12 and wiping cloth mounting bracket 11 is achieved by bonding bristle fabric and adhesive fastener 16.

[0120] By providing the phase change material 13 on the side of the main body facing the cloth 12, the main body 117 and the phase change material 13 can be separated. This allows for the selection of a suitable material for the main body 117, ensuring the support strength of the cloth mounting bracket 11 itself and reducing the impact of the phase change material 13 on the support strength of the bracket. This simplifies the selection of the phase change material 13. Furthermore, since the main body 117 covers the surface of the phase change material 13 facing away from the cloth 12, using a material with low thermal conductivity for the main body can improve the heat retention of the phase change material 13, reducing heat loss and improving the heating effect and heating time of the cloth 12.

[0121] In an example of the cleaning component 10 of this utility model, where the phase change material 13 is a solid-solid phase change material, the cloth mounting bracket 11 includes a main body 117 made of metal, which is covered by the phase change material 13. It should be noted that the metal material in this embodiment refers to a metal material with a certain supporting strength and rigidity, such as aluminum, carbon steel, or stainless steel. The phase change material 13 covering the main body 117 can mean that the exposed surface of the metal material is completely covered by the phase change material 13, or it can mean that a portion of the metal material is covered by the phase change material 13, such as the side of the metal material facing the cloth 12 being covered by the phase change material 13. By setting the main body 117 to be made of metal and having the phase change material 13 cover the metal material, the main body 117 can provide better support, thereby improving the supporting strength of the cloth mounting bracket 11. Simultaneously, since the phase change material 13 covers the metal material, the metal material can provide better support for the phase change material 13, thus reducing the difficulty in selecting the phase change material 13. Furthermore, by wrapping the phase change material 13 around the outside of the main body 117, the amount of phase change material 13 can be increased, which is beneficial to improving the heat storage performance of the phase change material 13 and thus improving the heating effect of the phase change material 13 on the cloth 12.

[0122] Referring to Figures 10 and 11, this utility model further provides a cleaning system 30, which includes the cleaning device 20 and base station 31 as described in the above example. The base station 31 includes a base station body 315 and a base 311, with the base 311 disposed at the lower end of the base station body 315. A receiving cavity 3112 for accommodating the cleaning device 20 is provided between the base 311 and the base station body 315. The base 311 is provided with a cleaning tank 312 for containing cleaning fluid, located at the bottom of the receiving cavity 3112, and capable of accommodating the cleaning component 10 on the cleaning device 20. The cleaning fluid is contained within the cleaning tank 312. The shape and number of cleaning tanks 312 correspond to the shape and number of cloths 12 on the cleaning component 10. Preferably, in this embodiment, two cleaning tanks 312 are provided, symmetrically installed at the bottom of the receiving cavity 3112. The cleaning device 20 is equipped with two cleaning components 10. After returning to the base station 31, the cleaning device 20 enters the receiving cavity 3112, and the rag 12 on the cleaning component 10 enters the cleaning tank 312. The rag 12 is cleaned by the rotational movement between the rag 12 and the cleaning tank 312. It should be noted that the base station 31 may also include conventional components of the existing base station 31, such as an energy system, a negative pressure suction system, a sewage tank, and a clean water tank, which will not be described in detail here.

[0123] Please refer to Figures 12 and 14. The cleaning tank 312 is equipped with a heating device 32 for heating the cleaning fluid. In the prior art, a heating element is generally installed in the water line of the base station 31 for heating. During long-term use, scale easily accumulates inside the heating element, making it difficult to maintain. In this solution, the heating device 32 directly heats the cleaning fluid in the cleaning tank 312 of the base station 31. This design makes it less likely for scale to form inside the cleaning tank 312. Even if scale does form, the cleaning tank 312 is easy to maintain, for example, by disassembling the cleaning tank 312 for cleaning.

[0124] Specifically, the heating device 32 can be installed at any location in the cleaning tank 312, such as the bottom wall or side wall of the cleaning tank 312, as long as it can heat the cleaning fluid. The specific structure of the heating device 32 can be an electric heating wire module, an electric heating plate module, a phase change material heating module, etc. The heating method of the heating device 32 is not limited. For example, it can directly heat the cleaning fluid located in the cleaning pan, or it can preheat the cleaning fluid entering the cleaning pan so that the heated cleaning fluid is directly introduced into the cleaning pan. Since the heating device 32 is installed in the cleaning tank 312, the distance between the heating device 32 and the cleaning tank 312 can be shortened, thereby reducing the heat loss during the transportation of the cleaning fluid, which is conducive to improving the heating efficiency of the cleaning fluid and playing a role in energy saving and emission reduction.

[0125] When the cleaning equipment 20 returns to the base station 31 after completing a cleaning operation, the cleaning component 10 is placed in the cleaning tank 312. The rag 12 comes into contact with the cleaning fluid in the cleaning tank 312. If the rag 12 needs to be cleaned with hot water, the heating device 32 is activated to heat the cleaning fluid. The rag 12 is then cleaned in the heated cleaning fluid. At this time, the phase change material 13 on the cleaning component 10 absorbs and stores the heat from the cleaning fluid. After the rag 12 has completed the cleaning operation, the cleaning equipment 20 detaches from the base station 31 and performs a cleaning operation on the ground. At this time, the phase change material 13 releases heat and conducts the heat to the rag 12, allowing the rag 12 to receive heat replenishment. This extends the time that the rag 12 can spend mopping with hot water and improves the cleaning effect of the rag 12.

[0126] It should be noted that although the purpose of installing the heating device 32 in the cleaning tank 312 is to allow the phase change material 13 on the cleaning component 10 to absorb heat during the cleaning operation, thereby providing heat to the mop 12, extending the hot mopping time of the mop 12, and improving the cleaning effect of the mop 12, in some other embodiments, the heating device 32 can also be installed in the cleaning tank 312 when the cleaning component 10 does not have a phase change material 13. In this case, the heating device 32 can heat the cleaning liquid in the cleaning tank 312 to achieve hot water cleaning of the mop 12, thereby improving the cleaning effect of the mop 12.

[0127] Referring to Figures 10 and 12, in one example of the cleaning system 30 of this utility model, the receiving cavity 3112 is provided with a channel opening 3111 for the cleaning equipment 20 to enter and exit. The cleaning tank 312 includes a front tank portion 3121 disposed near the channel opening 3111 and a rear tank portion 3122 disposed away from the channel opening 3111. The bottom wall height of the front tank portion 3121 is lower than the bottom wall height of the rear tank portion 3122, that is, the depth of the front tank portion 3121 is greater than the depth of the rear tank portion 3122. A heating device 32 is disposed in the front tank portion 3121, as shown in Figure 14. The heating device 32 can be part of the bottom wall of the front tank portion 3121, or it can be a separate heating element disposed on the side of the bottom wall of the front tank portion 3121 facing the ground. It achieves heating of the bottom wall of the front tank portion 3121 through thermally conductive connection with the bottom wall of the front tank portion 3121. Optionally, in this embodiment, a mounting cavity 314 is provided on the side of the bottom wall of the front groove 3121 facing the ground, and the heating device 32 is disposed in the mounting cavity 314. Specifically, referring to Figures 12 and 14, the heating device 32 includes a heating tube 321 and a heat-conducting element 322. The heat-conducting element 322 forms the bottom wall of the front groove 3121 and is thermally connected to the heating tube 321, thereby realizing the heating of the front groove 3121 by the heating device 32. Furthermore, a cover plate 313 is also provided at the opening of the mounting cavity 314. The cover plate 313 seals the mounting cavity 314 to reduce the heat conduction from the heating device 32 to the ground and to protect the heating device 32. By making the bottom wall height of the front tank 3121 lower than the bottom wall height of the rear tank 3122, and by placing the heating device 32 in the front tank 3121, more cleaning fluid can be stored in the front tank 3121, thereby making the heating device 32 have a better heating effect on the cleaning fluid and a higher heating efficiency.

[0128] Please refer to Figures 10, 12, and 13. In one example of the cleaning system 30 of this utility model, the base station 31 includes a liquid supply pipeline (not shown in the figures). A water spray hole 3123 is provided inside the cleaning tank 312, and the water spray hole 3123 is connected to the liquid supply pipeline. The cleaning liquid enters the interior of the cleaning tank 312 through the water spray hole 3123 via the liquid supply pipeline. A protrusion 3124 is provided on the bottom wall of the cleaning tank 312, dividing the cleaning tank 312 into a front tank portion 3121 and a rear tank portion 3122. The protrusion 3124 extends radially along the cleaning tank 312, and a cleaning rib 3125 is provided at one end of the protrusion 3124. The cleaning rib 3125 is an elongated protruding structure extending from the center of the cleaning tank 312 to one side radially along the cleaning tank 312. A water spray hole 3123 is provided at the other end of the protrusion 3124. Multiple water spray holes 3123 are arranged along the length of the protrusion 3124, and the water spray direction of the water spray holes 3123 is inclined to the front groove 3121 so that the water landing point of the water spray holes 3123 is located at the bottom wall of the front groove 3121. This arrangement allows the water spray holes 3123 to spray water onto the front groove 3121 in a timely manner when the cleaning tank 312 is accidentally bumped or needs to be moved, thereby cooling the front groove 3121 and reducing the risk of burns to surrounding objects or personnel. It should be noted that when the cleaning component 10 is not working, the instant heating component and heating device 32 in the base station 31 usually stop heating. Therefore, when the cleaning tank 3122 is accidentally bumped or moved, cool water will spray from the water spray holes 3123 to cool the front groove 3121.

[0129] In one example of the cleaning system 30 of this utility model, the base station 31 includes a liquid supply pipeline connected to the cleaning tank 312, and an instant heating component is provided on the liquid supply pipeline to heat the cleaning liquid. The outlet of the instant heating component is connected to the cleaning tank 312.

[0130] This configuration allows the cleaning fluid in the cleaning tank 312 to be preheated by the instant heating component and then further heated by the heating device 32. This double heating improves the efficiency of the heating device 32 and reduces the heating temperature of the instant heating component, thus decreasing the likelihood of scale buildup and maintenance frequency. Furthermore, the cleaning component of this invention incorporates a phase change material, which heats the mop during cleaning, enabling hot mopping and improving cleaning effectiveness. The high energy density of the phase change material allows it to absorb and release significant amounts of heat during the phase change process, storing a large amount of thermal energy in a relatively small volume or mass. This saves installation space and reduces the overall weight of the cleaning component. In addition, since phase change materials only need to absorb the heat from the cleaning fluid or the heating element that heats the cleaning fluid when the cloth is being cleaned, without the need for an additional heat source for the cleaning components, the structure is safer, simpler, and more energy-efficient.

[0131] Therefore, this utility model effectively overcomes some practical problems in the prior art, thus possessing high utilization value and significance. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
