Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a cleaning component, a cleaning device and a cleaning system. Background Art

[0002] Existing cleaning devices are generally equipped with a mopping module for wet mopping, but this is usually done with room-temperature water, making it less effective at removing stubborn stains and oily dirt. This is especially true at lower room temperatures, where the cleaning effect is further impaired. Therefore, the cleaning capabilities of cleaning devices need to be improved. Utility Model Content

[0003] In view of the above shortcomings of the prior art, the present invention provides a cleaning assembly, a cleaning device and a cleaning system to improve the technical problem that the prior cleaning equipment uses normal temperature water for cleaning, resulting in poor cleaning effect.

[0004] To achieve the above-mentioned purpose and other related purposes, the present invention provides a cleaning component, which includes: a rag mounting rack and a rag; the rag is installed on the rag mounting rack; wherein the rag mounting rack and / or the rag include a phase change material, and the phase change material is thermally connected to the rag to absorb heat from a heat source when the rag is in a non-cleaning operation, and release heat to the rag when the rag is in a cleaning operation; the non-cleaning operation includes at least part of the cleaning process, the drying process, and the soaking and heating process of the rag.

[0005] The beneficial effects of such a setting are as follows: by providing a phase change material, the cleaning component can heat the rag through the phase change material during non-cleaning operations, thereby achieving hot mopping of the rag, thereby improving the cleaning effect of the cleaning component on the floor. At the same time, since the phase change material has a high energy density, it can absorb or release a large amount of heat during the phase change process, and can store a large amount of thermal energy in a relatively small volume or mass, thereby saving the installation space occupied by the cleaning component and reducing the overall mass of the cleaning component. In addition, since the phase change material only needs to absorb the heat of the cleaning liquid or the heating element that heats the cleaning liquid when the rag is cleaning, and there is no need to set up an additional heat source for the cleaning component, the structure is safer, simpler and more energy-efficient.

[0006] In one example of the cleaning assembly of the present invention, the heat source includes a heating device and / or hot water.

[0007] The beneficial effect of this arrangement is that by setting the heat source as a heating device and / or hot water, the heating efficiency of the rag can be improved, thereby improving the heat absorption efficiency of the phase change material, thereby facilitating the improvement of the cleaning efficiency of the cleaning component.

[0008] In one example of the cleaning component of the present invention, a connecting portion that can be detachably connected to the driving component is provided on the side of the rag mounting bracket facing away from the rag. The connecting portion includes a magnetic structure that can be attracted to the driving shaft of the driving component, or the connecting portion includes a snap structure that can be snapped into the driving component.

[0009] The beneficial effect of such a setting is that by providing a magnetic structure and a snap-fit ​​structure, no other tools are required when installing between the connecting portion and the driving assembly, so installation and disassembly are very convenient.

[0010] In one example of the cleaning component of the present invention, a buffer portion for absorbing the impact force of the edge of the cleaning component is provided on the outer periphery of the rag mounting frame.

[0011] This design has the following beneficial effects: by providing a buffer portion on the outer periphery of the mop mount, it can effectively mitigate the impact of external collision forces on the cleaning components themselves, reducing wear on the mop mount and extending the service life of the cleaning components. Furthermore, the buffer structure can also reduce scratches and impacts on furniture and walls during cleaning operations, reducing damage to furniture and walls, and also reducing collision noise generated during cleaning operations.

[0012] In one example of the cleaning component of the present invention, the buffer portion includes a soft rubber structure, and the soft rubber structure is provided with a plurality of deformable hollow areas.

[0013] This arrangement offers the following advantages: By providing a soft rubber structure with multiple deformable hollow areas, the soft rubber structure can be hot-melt-molded onto the outer periphery of the rag mounting frame, making molding and installation more convenient and eliminating the need for additional mechanical connections. Furthermore, the soft rubber structure, combined with the deformable hollow areas, provides a superior cushioning effect around the outer periphery of the rag mounting frame.

[0014] In one example of the cleaning assembly of the present invention, the rag mounting frame is provided with a sealed cavity filled with a phase change material.

[0015] The beneficial effect of this arrangement is that by providing a sealed cavity on the rag mounting frame and filling the sealed cavity with the phase change material, this arrangement not only prevents the probability of leakage of the phase change material during the phase change process, thereby ensuring the heat storage performance of the phase change material, but also reduces the influence of external factors (such as air and moisture) during the phase change process, thereby maintaining the stability of the phase change material performance.

[0016] In one example of the cleaning assembly of the present invention, the rag mounting frame is further provided with an opening communicating with the sealed cavity, through which the liquid phase change material is injected into the sealed cavity, and the opening is covered with a sealing cover.

[0017] This arrangement offers the following advantages: Liquid phase-change material can be injected into the sealed cavity through an opening provided on the rag mounting bracket, allowing the sealed cavity to be manufactured as an integral structure, thus further ensuring the sealing performance of the sealed cavity. Furthermore, the opening allows for easy inspection of the status of the phase-change material within the sealed cavity, allowing for timely monitoring of changes in the phase-change material's heat storage performance.

[0018] In one example of the cleaning component of the present invention, the rag mounting bracket includes an upper cover and a lower cover, which are sealed and connected to form a sealed cavity; the rag mounting bracket also includes hot melt adhesive, and the upper cover and the lower cover are connected by hot melt adhesive.

[0019] The beneficial effects of such a setting are as follows: by setting the upper cover body and the lower cover body, the upper cover body and the lower cover body are connected to form a sealed cavity. Such a setting can facilitate the split design of the rag mounting frame, facilitate injection molding, and help reduce processing costs. At the same time, before the upper cover body and the lower cover body are closed, the solid phase change material can be pre-installed in the sealed cavity, and then the sealing of the sealed cavity is achieved through the connection between the upper cover body and the lower cover body, which facilitates the installation of the solid phase change material in the sealed cavity. At the same time, by setting hot melt adhesive, a molten connection is formed between the upper cover body and the lower cover body. Such a setting has a higher connection efficiency during mass production than that using connection methods such as bolt fasteners, and the sealing performance is also easier to ensure. In an example of the cleaning component of the present invention, the lower cover body is thermally connected to the rag, and the thermal conductivity of the lower cover body is greater than the thermal conductivity of the upper cover body.

[0020] This arrangement has the beneficial effect of increasing the thermal conductivity of the lower cover to a greater value than that of the upper cover. This arrangement allows the heat stored in the phase-change material to be quickly transferred through the lower cover to the rag, heating it and improving its heating efficiency and effectiveness. It also reduces the amount of heat transferred from the phase-change material within the sealed cavity to the outside through the upper cover, thereby reducing heat loss from the phase-change material and further improving its heating effect on the rag.

[0021] In one example of the cleaning assembly of the present invention, a rubber layer is provided on a side of the upper cover body facing away from the lower cover body.

[0022] This arrangement has the beneficial effect of providing a rubber coating on the upper cover, which has a low thermal conductivity coefficient. This provides a shield for the exposed surface of the upper cover, thereby reducing the heat exchange rate between the upper cover and the surrounding air, and further reducing the heat transfer from the phase change material through the upper cover to the outside. Furthermore, the rubber coating increases friction between the end face of the drive shaft and the rag mounting bracket, thereby facilitating the removal of the cleaning assembly.

[0023] In an example of the cleaning assembly of the present invention, the lower cover includes a heat-conducting rib, and the heat-conducting rib at least partially extends into the interior of the sealed cavity.

[0024] The beneficial effect of this arrangement is as follows: by arranging heat-conducting ribs on the lower cover body and making the heat-conducting ribs at least partially extend into the interior of the sealed cavity, the contact area between the phase change material and the lower cover body can be increased, thereby increasing the heat conduction efficiency between the phase change material and the lower cover body, and ultimately improving the heat transfer efficiency of the phase change material to the rag, thereby ensuring the hot mopping effect of the rag.

[0025] In one example of the cleaning component of the present invention, the rag includes a fabric layer, a water-absorbing layer and an adhesive layer connected in sequence from bottom to top, and a bonding portion is provided on the side of the rag mounting frame facing the rag, and the adhesive layer is bonded to the adhesive portion; the phase change material is provided between the fabric layer and the water-absorbing layer and / or between the water-absorbing layer and the adhesive layer.

[0026] This arrangement offers the following beneficial effects: By placing the phase-change material between the fabric layer and the water-absorbing layer and / or between the water-absorbing layer and the adhesive layer, the phase-change material can be completely immersed in the cleaning fluid during cleaning. This increases the contact area between the phase-change material and the cleaning fluid, thereby improving the heat storage efficiency of the phase-change material. Furthermore, during cleaning, the heat conduction path between the phase-change material and the fabric layer is shortened, thereby reducing heat loss from the phase-change material to the fabric layer. This improves the thermal conductivity of the phase-change material to the fabric layer, thereby extending the hot mopping time of the fabric layer and further enhancing the cleaning effectiveness of the rag.

[0027] In an example of the cleaning component of the present invention, the sum of the areas of the upper surface and the lower surface of the water-absorbing layer is S1, and the area S2 of the water-absorbing layer covered by the phase change material is less than or equal to 1 / 2 of S1.

[0028] The beneficial effect of this setting is: the area S2 of the water-absorbing layer covered by the phase change material is set to be less than or equal to 1 / 2 of S1. Within this range, the water absorption performance of the water-absorbing layer can be met to ensure the wet mopping effect of the rag, and the heat storage requirements of the phase change material can be taken into account to ensure the hot mopping effect of the rag.

[0029] In one example of the cleaning component of the present invention, a sealing interlayer is provided between the fabric layer and the water-absorbing layer and / or between the water-absorbing layer and the adhesive layer, and the phase change material is filled in the sealing interlayer.

[0030] The beneficial effect of this arrangement is that by providing a sealing interlayer, not only can the probability of leakage during the phase change process of the phase change material be reduced, but also the installation and fixation of the phase change material on the rag can be facilitated, thereby reducing the difficulty of the installation process of the phase change material on the rag.

[0031] In an example of the cleaning component of the present invention, a microcapsule layer is provided on the upper surface and / or the lower surface of the water absorption layer. The microcapsule layer includes a plurality of microcapsules filled with phase change material.

[0032] This arrangement offers the following benefits: By providing a microcapsule layer and filling it with phase-change material, leakage of the phase-change material during the phase-change process is prevented. Furthermore, the microcapsule structure prevents leakage from the sutured pores of the cleaning cloth, effectively retaining the phase-change material within the cloth and reducing its loss during use. Furthermore, within the same installation area, the microcapsule structure increases the contact area between the phase-change material and the cleaning fluid, thereby improving the heat storage efficiency of the phase-change material.

[0033] In one example of the cleaning component of the present invention, the upper surface of the water absorbing layer is coated with multiple first microcapsule layers arranged at intervals, and the lower surface of the water absorbing layer is coated with multiple second microcapsule layers arranged at intervals, and the multiple first microcapsule layers and the multiple second microcapsule layers are arranged alternately up and down.

[0034] This arrangement has the following beneficial effects: on the one hand, while ensuring the required water absorption performance of the water-absorbing layer, the area of ​​the microcapsule layer on the water-absorbing layer can be increased as much as possible, thereby increasing the amount of phase change material used to ensure the phase change material's thermal conductivity to the fabric layer. On the other hand, because the first and second microcapsule layers are staggered, when the mop is replenished with water, water enters from the upper surface of the water-absorbing layer, bypasses the staggered position of the first and second microcapsules, and then flows from the lower surface of the water-absorbing layer to the fabric layer. This increases the length of the water flow path within the water-absorbing layer, prolonging the water's residence time within the mop and increasing the contact time between the water and the phase change material. This in turn increases the water's outlet temperature, thereby enhancing the mop's thermal mopping effect.

[0035] In an example of the cleaning assembly of the present invention, the phase change material is a solid-solid phase change material, and the rag mounting bracket is at least partially composed of the phase change material.

[0036] This arrangement offers the following benefits: It allows for direct contact between the phase-change material and the rag, thereby reducing the heat transfer path between them and further enhancing the heating effect of the phase-change material on the rag. Furthermore, it eliminates the need for additional phase-change material on the rag mounting bracket, thus reducing the weight of the bracket itself and contributing to its lightweight design.

[0037] In one example of the cleaning component of the present invention, the rag mounting frame is entirely injection-molded by phase change material.

[0038] This arrangement provides a beneficial effect: It allows for a large area and mass of phase-change material on the mop mounting frame. This increases the contact area between the phase-change material and the cleaning fluid during the mop cleaning process, improving the phase-change material's heat storage efficiency and heat capacity. This extends the heat transfer time from the phase-change material to the mop during the cleaning process, further enhancing the mop's thermal mopping performance.

[0039] In an example of the cleaning assembly of the present invention, the rag mounting frame includes a main body, a side of the main body facing the rag includes a phase change material, and the phase change material at least partially abuts against the rag.

[0040] This arrangement has the beneficial effect of providing the phase-change material on the side of the main body facing the rag, thereby achieving a separate arrangement of the main body and the phase-change material. This allows for the proper selection of the main body material to ensure the support strength of the rag mounting frame itself, thereby reducing the impact of the phase-change material on the support strength of the rag mounting frame, thereby facilitating the selection of the phase-change material. Furthermore, since the main body covers the surface of the phase-change material facing away from the rag, selecting a material with a lower thermal conductivity for the main body also enhances the thermal insulation effect of the phase-change material, reduces heat loss from the phase-change material to the outside, and improves the heating effect and duration of the phase-change material on the rag.

[0041] In an example of the cleaning component of the present invention, the rag mounting bracket includes a main body, which is made of metal and wrapped with a phase change material.

[0042] The beneficial effects of this arrangement are as follows: by providing a metal main body and wrapping the metal with a phase change material, the metal main body provides better support, thereby increasing the support strength of the rag mounting frame. At the same time, because the phase change material wraps the metal, the metal material provides better support for the phase change material, thereby reducing the difficulty of selecting the phase change material. Furthermore, wrapping the phase change material around the outside of the main body can also increase the amount of phase change material used, which is beneficial for improving the heat storage performance of the phase change material and thereby enhancing the heating effect of the phase change material on the rag.

[0043] The present invention also provides a cleaning device, which includes the cleaning component of any of the above examples.

[0044] In an example of the cleaning device of the present invention, the cleaning device includes a body, and the cleaning device includes two cleaning components. At least one cleaning component can be movably connected to the body and has a retracted position and an outward swing position relative to the body. When the cleaning component is in the outward swing position, it is away from the body relative to the retracted position, and the cleaning device can perform edge cleaning; when the rag of the cleaning component absorbs heat from the heat source, the cleaning component is in the retracted position.

[0045] The beneficial effect of this setting is: since the cleaning component has an inward retracted position and an outward swing position relative to the fuselage, the installation position of the cleaning component relative to the fuselage can be adjusted, which not only ensures the cleaning effect in the normal cleaning area, but also achieves edge cleaning in the working area. Therefore, the cleaning component can better meet the needs of various cleaning conditions and has a better all-round cleaning effect on the ground.

[0046] The present invention further provides a cleaning system, which includes the cleaning device and a base station in the above example. The base station includes a base, and the base is provided with a cleaning tank for accommodating cleaning liquid, wherein the cleaning tank is provided with a heating device for heating the cleaning liquid.

[0047] This arrangement offers the following benefits: Because the heating device is installed within the cleaning tank, the distance between the heating device and the tank can be shortened, thereby reducing heat loss during the cleaning liquid transfer process. This improves the cleaning liquid's heating efficiency and contributes to energy conservation and emission reduction. Furthermore, the phase change material absorbs and stores heat during the cleaning process, transferring the stored heat to the cleaning cloth during the cleaning operation, replenishing the cloth's heat and extending the time it can be used for mopping with hot water, thereby improving the cleaning effect.

[0048] In one example of the cleaning system of the present invention, the base is provided with a passage opening for the cleaning equipment to enter and exit, and the cleaning tank includes a front tank portion arranged close to the passage opening and a rear tank portion arranged away from the passage opening. The bottom wall height of the front tank portion is lower than the bottom wall height of the rear tank portion, and the heating device is arranged in the front tank portion.

[0049] The beneficial effect of this arrangement is: by making the bottom wall height of the front groove lower than the bottom wall height of the rear groove, and arranging the heating device in the front groove, more cleaning liquid can be stored in the front groove, thereby making the heating device have a better heating effect on the cleaning liquid and a higher heating efficiency.

[0050] In an example of the cleaning system of the present invention, the base station includes a liquid supply pipeline, and a water spray hole is provided in the cleaning tank, which is connected to the liquid supply pipeline; the water spraying direction of the water spray hole is inclined toward the front tank so that the water landing point of the water spray hole is located in the front tank.

[0051] The beneficial effect of this arrangement is that when the cleaning tank is accidentally bumped or moved, the water spray hole can spray water to the front tank part in time to cool the front tank part in time and reduce burns to surrounding objects or personnel.

[0052] In an example of the cleaning system of the present invention, the base station includes a liquid supply pipeline connected to the cleaning tank. A heating component is provided on the liquid supply pipeline to heat the cleaning liquid, and the outlet of the heating component is connected to the cleaning tank.

[0053] The beneficial effects of this arrangement are as follows: the cleaning liquid in the cleaning tank is pre-heated by the instant heating component, and then heated by the heating device, so that the cleaning liquid in the cleaning tank can be heated twice. This arrangement can improve the heating efficiency of the cleaning liquid by the heating device. At the same time, it can also reduce the heating temperature of the cleaning liquid by the instant heating component, thereby reducing the probability of scale residue inside the instant heating component due to excessive temperature, and reducing the maintenance frequency of the instant heating component.

[0078] See also Figures 1 to 18 The utility model provides a cleaning component 10, a cleaning device 20 and a cleaning system 30. The cleaning component 10 is provided with a phase change material 13 on a rag mounting frame 11 and / or a rag 12, and the phase change material 13 is thermally connected to the rag 12. In this way, during the cleaning process of the rag 12, the phase change material 13 can absorb the heat of the stored heat source, and release the heat to heat the rag 12 when the rag 12 is cleaning, so that the hot mopping of the rag 12 can be achieved, which is beneficial for removing stubborn stains, oil stains, etc. on the ground, thereby improving the cleaning effect of the cleaning component 10.

[0079] See also Figure 1 and Figure 9 The cleaning device 20 provided by the present invention includes a body 21 and a cleaning component 10.

[0080] The interior of the body 21 has a storage space for accommodating various components of the cleaning device 20. The shape of the body 21 can be any shape, for example, the shape of the body 21 can be circular, oval, or D-shaped, etc. The cleaning device 20 can also include a walking assembly conventionally provided on existing cleaning devices 20, and the walking assembly is provided below the body 21 to drive the cleaning device 20 to achieve self-propelled movement. The specific structure of the walking assembly and the connection structure between the walking assembly and the body 21 can refer to the relevant structural description of the existing cleaning device 20, and will not be repeated here.

[0081] The cleaning assembly 10 can be detachably connected to the body 21, such as by snap-fitting, bolting, or the like. The cleaning assembly 10 is configured for wet mopping. The body 21 is provided with a water supply mechanism (not shown). The water outlet of the water supply mechanism communicates with the rag 12 to supply liquid to the rag 12 on the cleaning assembly 10. The liquid can be cleaning fluid or ordinary tap water, depending on the wet mopping requirements of the cleaning device 20.

[0082] See also Figure 10 and Figure 11The cleaning device 20 is correspondingly configured with a base station 31. The base station 31 is provided with a cleaning structure. The cleaning structure can be an existing cleaning tank structure or any other structure capable of containing cleaning liquid and capable of cleaning the rag 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 provided with a heating device that can heat the cleaning liquid contained in the cleaning structure, achieving thermal cleaning of the cleaning component 10, thereby enhancing the cleaning effect of the cleaning component 10.

[0083] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 9 In one embodiment of the present invention, the cleaning assembly 10 includes a rag mounting frame 11 and a rag 12. The rag mounting frame 11 is installed below the body 21, and the rag 12 is installed on the rag mounting frame 11. The rag mounting frame 11 and the rag 12 can be detachably connected or fixedly connected. The rag 12 can be a round rag, a rectangular rag, a polygonal rag, etc. In this embodiment, for the convenience of description, the rag 12 is a round rag. A round rag means that the cleaning working surface between the rag 12 and the ground has a circular outline.

[0084] It should be noted that the number of cleaning components 10 provided on the cleaning device 20 can be one group or multiple groups, depending on the cleaning area and cleaning efficiency requirements of the cleaning device 20. Figure 9 and Figure 11 The cleaning device 20 is provided with two groups of cleaning components 10, and the two groups of cleaning components 10 are symmetrically installed at the bottom of the fuselage 21 to achieve the cleaning operation on the ground during the walking process of the cleaning device 20.

[0085] See also Figures 16 to 18 In an example of the cleaning device 20 of the present invention, the cleaning device 20 includes two cleaning components 10, and both cleaning components 10 can be movably connected to the body 21. The movably connected body 21 means that the rotation axis of the cleaning component 10 can be adjusted in a plane relative to the body 21. Each cleaning component 10 has two states relative to the body 21: a retracted position and an outward swing position. The moving direction of the body 21 is defined as the length direction of the body 21 (e.g., Figure 17 The direction perpendicular to the moving direction of the fuselage 21 is the width direction of the fuselage 21 (as shown in the X-axis). Figure 17(as shown by the Y-axis in the middle). When the cleaning component 10 is in the outward swing position, relative to the retracted position, the rotation axis of the cleaning component 10 moves toward the outside of the fuselage 21 along the width direction of the fuselage 21, and the two cleaning components 10 move away from each other, and the cleaning components 10 on each side extend to the outside of the width direction of the fuselage 21, thereby enabling the cleaning operation of the cleaning device 20 along the edge. When the cleaning component 10 is in the retracted position, the rotation axis of the cleaning component 10 moves toward the inside of the fuselage 21 along the width direction of the fuselage 21, and the two cleaning components 10 approach each other, and the cleaning components 10 on each side retract to the inside of the width direction of the fuselage 21 to ensure the cleaning effect in the working area between the two cleaning components 10. It should be noted that the specific structure of the cleaning component 10 and the fuselage 21 that can achieve the retracted position and the outward swing position can refer to the relevant structural description in the existing cleaning device 10, and will not be repeated here.

[0086] In another embodiment, one of the two cleaning assemblies 10 can have an outward swing position and a retracted position, while the other cleaning assembly 10 is fixedly connected to the body 21 in a flat position. This also enables the cleaning device 20 to perform edge cleaning operations. When the cleaning cloth 12 of the cleaning assembly 10 needs to absorb heat from the heat source, the cleaning assembly 10 is in the retracted position. This reduces the space occupied by the cleaning device 20 during the cleaning process of the cleaning cloth 12 and facilitates the entry and exit of the cleaning device 20 from the base station 31.

[0087] Since the cleaning component 10 has an inward-retracted position and an outward-swinged position relative to the fuselage 21, such a setting can realize the adjustment of the installation position of the cleaning component 10 relative to the fuselage 21, which not only ensures the cleaning effect in the area between the two cleaning components 10, but also realizes the edge cleaning in the working area. Therefore, the cleaning component 10 can better meet the needs of various cleaning working conditions, which is conducive to improving the all-round cleaning effect of the ground.

[0088] See also Figure 3 、 Figure 4 and Figure 8 The rag mounting frame 11 includes a phase change material 13, which is thermally connected to the rag 12. The phase change material 13 can be a solid-liquid phase change material, that is, it can be transformed between solid and liquid within a certain temperature range. When the phase change material 13 changes from solid to liquid, it absorbs heat; when the phase change material 13 changes from liquid to solid, it releases heat. The phase change material 13 can also be a solid-solid phase change material, that is, a material that 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 the phase change material 13 changes from the second solid state to the first solid state, it releases heat. The state change of the phase change material 13 can realize the conversion of the rag mounting frame 11 between heat absorption and heat release.

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

[0090] Under the condition that the heat conduction requirements between the phase change material 13 and the rag 12 are met, the phase change material 13 can be arranged on the side of the rag mounting frame 11 facing the rag 12, so that the phase change material 13 and the rag 12 are in direct contact for heat conduction, such as Figure 8 The phase change material 13 can also be arranged in the sealed cavity of the rag mounting frame 11, and indirect heat conduction between the phase change material 13 and the rag 12 can be achieved through other heat conducting components, such as Figure 3 In another embodiment, the rag 12 may include the phase change material 13, that is, the phase change material 13 is provided on the rag 12, such as Figure 4 In other embodiments, the rag mounting frame 11 may include a portion of the phase change material 13, and the rag 12 may also include a portion of the phase change material 13, that is, the phase change material 13 may be partially disposed on the rag mounting frame 11 and partially disposed on the rag 12. During the actual design and production process, the specific placement of the phase change material 13 also needs to consider various factors, such as the heat absorption requirements of the rag 12, production process conditions, and production costs.

[0091] When the rag 12 is in a non-cleaning operation, the phase change material 13 absorbs heat from the heat source to store heat; when the rag 12 is in a cleaning operation, the phase change material 13 releases heat to the rag 12 to conduct heat to the rag 12, thereby achieving hot mopping of the rag 12. The heat source in this embodiment can be a cleaning liquid with a certain temperature, a heating element for heating the cleaning liquid, or a combination of a cleaning liquid and a heating element. The non-cleaning operation includes at least part of the cleaning process, the drying process, and the soaking and heating process of the rag 12. For example, in one embodiment, the non-cleaning operation can be any single process among the cleaning process, the drying process, and the hot water soaking process of the rag 12. In another embodiment, the non-cleaning operation can also be a combination of two or three of the cleaning process, the drying process, and the soaking and heating process of the rag 12.

[0092] By providing the phase change material 13, the cleaning assembly 10 can heat the rag 12 during non-cleaning operations, achieving hot mopping of the rag 12, thereby improving the cleaning efficiency of the cleaning assembly 10. Furthermore, due to the high energy density of the phase change material 13, it can absorb or release a large amount of heat during the phase change process, and can store a large amount of thermal energy in a relatively small volume or mass. This can save installation space on the cleaning assembly 10 and reduce the overall mass of the cleaning assembly 10. Furthermore, since the phase change material 13 only needs to absorb heat during at least a portion of the cleaning, drying, and soaking and heating processes of the rag 12, compared to prior art solutions that incorporate an active heating device within the cleaning apparatus to heat the rag, this embodiment does not require an additional heat source within the cleaning apparatus 20. This simplifies the circuit design within the cleaning apparatus 20 and streamlines its internal structure. Consequently, the overall structure of the cleaning apparatus 20 in this embodiment is more electrically safe, thereby reducing the probability of circuit failure during use.

[0093] In an example of the cleaning component 10 of the present invention, the heat source includes a heating device 32. The heating device 32 can be arranged in the cleaning tank 312 of the base station 31, or it can be arranged outside the base station 31. As long as the rag 12 can be heated when the rag 12 is in a non-cleaning operation, the phase change material 13 can absorb heat. In another embodiment, the heat source can also be hot water, and the hot water can be a heated cleaning liquid located in the cleaning tank 312, that is, when the rag 12 contacts the cleaning liquid in the cleaning tank 312, the phase change material 13 can absorb the heat of the cleaning liquid. The hot water can also be a liquid in a container outside the base station 31, and the liquid can be clean water or a cleaning liquid. When the rag 12 is immersed in the hot water in the container and heated, the phase change material 13 can also absorb the heat of the hot water. In other embodiments, the heat source can also be a combination of a heating device 32 and hot water. For example, a heating device 32 is provided inside the cleaning tank 312, and the 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 be in contact with the heating device 32 and the cleaning liquid at the same time, so that the phase change material 13 can absorb the heat of the heating device 32 and the heat of the cleaning liquid at the same time.

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

[0095] Considering the convenience of connecting the cleaning assembly 10 with the driving assembly 22 of the cleaning device 20, optionally, refer to Figure 2 、 Figure 3 and Figure 9 In an example of the cleaning component 10 of the present invention, a connecting portion 14 that can be detachably connected to the driving component 22 is provided on the side of the rag mounting frame 11 facing away from the rag 12. Specifically, the connecting portion 14 is connected to the drive shaft of the driving component 22 so as to drive the cleaning component 10 to perform cleaning operations when the driving component 22 is running. The connecting portion 14 can be a convex column structure or a groove structure, as long as it can be adapted to the driving shaft of the driving component 22. The connecting portion 14 includes a magnetic structure 141 that can be attracted to the driving shaft of the driving component 22. The magnetic structure 141 can have various forms. In an embodiment, the magnetic structure 141 can be a magnet, that is, the connecting portion 14 includes a magnet. In this case, the driving shaft is a ferromagnet. The connecting portion 14 and the driving shaft are magnetically connected to achieve an axial fixed connection between the connecting portion 14 and the driving shaft. In another embodiment, the magnetic structure 141 may be a ferromagnet, that is, the connecting portion 14 includes a ferromagnet, in which case the drive shaft is a magnet, and a magnetic connection may be achieved between the connecting portion 14 and the drive shaft. In other embodiments, the magnetic structure 141 may be a magnet, that is, the connecting portion 14 includes a magnet, in which case the drive shaft is also a magnet, and the polarity of the magnets of the connecting portion 14 and the drive shaft are opposite, in which case a magnetic connection may also be achieved between the connecting portion 14 and the drive shaft.

[0096] By setting up the magnetic attraction structure 141, no other tools are required when installing between the connecting part 14 and the driving component 22, so the installation is very convenient. At the same time, when removing the connecting part 14 from the driving component 22, a pulling force greater than the magnetic attraction force can be directly applied 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 the present invention, the connecting portion 14 includes a snap-fit ​​structure (not shown in the figure) that can be snap-fitted with the drive component 22. The snap-fit ​​structure can have various forms. For example, the snap-fit ​​structure can be a tapered hole structure. In this case, the drive shaft of the drive component 22 is a frustum structure. The frustum is snapped into the tapered hole to form a conical snap-fit ​​connection, thereby realizing a snap-fit ​​connection between the connecting portion 14 and the drive component 22. The snap-fit ​​structure can also be a plurality of wedge blocks arranged on the outer periphery of the connecting portion 14. In this case, the drive shaft of the drive component 22 is provided with a groove structure. The connecting portion 14 is inserted into the groove, and the plurality of wedge blocks are respectively abutted against the side walls of the groove along the circumferential direction of the drive shaft to form a friction abutment, thereby realizing a snap-fit ​​connection between the connecting portion 14 and the drive component 22. By providing a snap-fit ​​structure on the connecting portion 14, the assembly and disassembly connection between the connecting portion 14 and the drive component 22 can also be facilitated. In order to reduce the collision impact force generated when the cleaning component 10 comes into contact with surrounding obstacles during the cleaning operation, please refer to Figure 2 and Figure 3In one example of the cleaning assembly 10 of the present invention, a buffer portion 111 is provided on the outer periphery of the rag mounting frame 11 to absorb impact forces from the edge of the cleaning assembly 10. The buffer portion 111 can be an annular structure made of a plastic or silicone material with a certain degree of flexibility. When the annular structure is impacted, it can absorb the impact force through its own elastic-plastic deformation, thereby providing a buffering effect. The buffer portion 111 can also be an elastic structure provided on the outer periphery of the rag mounting frame 11, such as a combination of a spring and a baffle. When the baffle is impacted, the spring absorbs the impact force through elastic deformation, thereby providing a buffering effect. By providing the buffer portion 111 on the outer periphery of the rag mounting frame 11, on the one hand, it can effectively mitigate the impact of external impact forces on the cleaning assembly 10 itself, reduce the degree of wear on the rag mounting frame 11, and increase the service life of the cleaning assembly 10. On the other hand, the buffer portion 111 can also reduce the scratching and impact of the rag mounting frame 11 on furniture and walls during cleaning operations, thereby reducing the degree of damage to furniture and walls, and also reduce the collision noise generated during cleaning operations.

[0098] See also Figure 2 and Figure 3 In an example of the cleaning component 10 of the present invention, the buffer portion 111 includes a soft gel structure 112, and the soft gel structure 112 is provided with a plurality of deformable hollow areas 1121. The material of the soft gel structure 112 may be silicone, rubber, etc. The soft gel structure 112 may be a ring structure arranged around the outer periphery of the rag mounting frame 11, or it may be a plurality of block structures arranged at intervals, etc. The deformable hollow areas 1121 provided on the soft gel structure 112 may be structures of various shapes such as circular holes, square holes or polygonal holes. Optionally, in order to obtain a uniform buffering effect in the circumferential direction of the rag mounting frame 11, optionally, in this embodiment, the soft gel structure 112 is a ring structure arranged coaxially with the rag mounting frame 11, and a plurality of deformable hollow areas 1121 are arranged in an array on the ring structure. By providing 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 hot-melt-molded to the periphery of the rag mounting frame 11, making molding and installation more convenient and eliminating the need for additional mechanical connections. Furthermore, the soft rubber structure 112 combined with the deformable hollow areas 1121 provide a better cushioning effect around the periphery of the rag mounting frame 11.

[0099] Considering that the commonly used phase change materials 13 are generally solid-liquid phase change materials, therefore, when the phase change material 13 changes from solid to liquid during the phase change process, the leakage problem of the phase change material 13 needs to be considered. Based on this, optionally, refer to Figure 3In an example of the cleaning component 10 of the present invention, the rag mounting frame 11 is provided with a sealed cavity 113, and the sealed cavity 113 is filled with a phase change material 13. The sealed cavity 113 can be an integral annular cavity structure arranged around the rag mounting frame 11, or a plurality of local cavity structures arranged at intervals. The specific structure of the sealed cavity 113 needs to be determined according to the structural shape of the rag mounting frame 11. The phase change material 13 can fill the entire sealed cavity 113, or it can partially fill the sealed cavity 113. There are many ways to form the sealed cavity 113. For example, the sealed cavity 113 can be formed when the rag mounting frame 11 is integrally injection-molded, or the rag mounting frame 11 can be divided into two parts, upper and lower, to assemble to form the sealed cavity 113. In this embodiment, no specific limitation is made to this. It should be noted that the side of the sealed cavity 113 facing the rag 12 needs to have better thermal conductivity so that the heat of the phase change material 13 in the sealed cavity 113 can be effectively transferred to the rag 12, thereby heating the rag 12. In addition, in other embodiments, when the phase change material 13 is a solid-solid phase change material, the phase change material 13 can also be disposed in a sealed cavity 113. By disposing the sealed cavity 113 on the rag mounting frame 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, thereby ensuring the heat storage performance of the phase change material 13. Moreover, the sealed arrangement of the phase change material 13 can also reduce the influence of external factors (such as air, moisture, etc.) during the phase change process, thereby maintaining the stability of the performance of the phase change material 13.

[0100] There are many ways to fill the phase change material 13 in the sealed cavity 113. Optionally, in an example of the cleaning component 10 of the present invention, see Figure 3The rag mounting frame 11 is provided with an opening 114, which is connected to the sealed cavity 113, and the liquid phase change material 13 is injected into the sealed cavity 113 through the opening 114. The opening 114 can be provided at multiple positions such as the upper surface, lower surface or side of the rag mounting frame 11, and one or more openings 114 can be provided. When the sealed cavity 113 is an integral cavity structure, only one opening 114 can be provided. When the sealed cavity 113 is a plurality of cavity structures that are not connected to each other, at least one opening 114 needs to be provided on each cavity structure. The opening 114 can be a circular hole structure, a square hole structure or a special-shaped hole, and any shape structure that can meet the filling requirements of the liquid phase change material 13. Preferably, in this embodiment, the sealed cavity 113 is an integral cavity structure, and the rag mounting frame 11 is provided with an opening 114 connected to the sealed cavity 113 on the side away from the rag 12. The opening 114 is covered with a sealing cover 1141. The sealing cover 1141 can be detachably covered on the opening 114, for example, by a sealing threaded connection. It can also be non-detachably covered on the opening 114, for example, by being adhesively fixed to the opening 114, or by being hot-melt connected to the opening 114. By providing an opening 114 on the rag mounting frame 11 that is connected to the sealed cavity 113, the liquid phase change material 13 can be injected into the sealed cavity 113 through the opening 114, and the sealed cavity 113 can be made into an integrally molded structure, so that the sealing performance of the sealed cavity 113 is more easily guaranteed. At the same time, the use status of the phase change material in the sealed cavity 113 can also be conveniently checked through the opening 114, so as to timely understand the changes in the heat storage performance of the phase change material 13.

[0101] See also Figure 3In an example of the cleaning component 10 of the present invention, the rag mounting frame 11 includes an upper cover body 115 and a lower cover body 116, and the upper cover body 115 and the lower cover body 116 are sealed and connected to form a sealed cavity 113. The lower cover body 116 is arranged close to one side of the rag 12 and is connected to the rag 12. The upper cover body 115 and the lower cover body 116 can be sealed by fasteners such as bolts and seals. The upper cover body 115 and the lower cover body 116 can also be connected by hot melt adhesive to achieve a sealed connection between the two. The molding structure of the sealed cavity 113 is not limited. For example, the upper cover body 115 can be provided with a groove, and the lower cover body 116 blocks the groove opening to form the sealed cavity 113; the lower cover body 116 can also be provided with a groove, and the upper cover body 115 blocks the groove opening to form the sealed cavity 113, etc. By providing an upper cover 115 and a lower cover 116, the upper cover 115 and the lower cover 116 are connected to form a sealed cavity 113. This arrangement facilitates the split design of the rag mounting frame 11, facilitates injection molding, and helps reduce processing costs. At the same time, before the upper cover 115 and the lower cover 116 are closed, the solid phase change material 13 can be pre-installed in the sealed cavity 113. Then, by connecting the upper cover 115 and the lower cover 116, the sealed cavity 113 is sealed, which facilitates the installation of the solid phase change material 13 in the sealed cavity 113.

[0102] Although there are many ways to connect the upper cover 115 and the lower cover 116, considering the assembly efficiency of the rag mounting frame 11, preferably, in an example of the cleaning assembly 10 of the present invention, refer to Figure 3 The rag mounting frame 11 also includes a hot melt adhesive 118, and the upper cover 115 and the lower cover 116 are connected by hot melt adhesive 118. The hot melt adhesive 118 can be of various types such as EVA hot melt adhesive, PUR hot melt adhesive, etc., and needs to be determined according to the material and connection performance requirements of the upper cover 115 and the lower cover 116 during actual use. The hot melt adhesive 118 is arranged at the butt joint between the upper cover 115 and the lower cover 116, that is, the two 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 the hot melt adhesive 118, and at the same time, a butt joint pressure is applied between the upper cover 115 and the lower cover 116 until the hot melt adhesive 118 is cooled and solidified again, so that a sealed and fixed connection between the upper cover 115 and the lower cover 116 can be achieved. By setting hot melt adhesive 118, a molten connection is formed between the upper cover body 115 and the lower cover body 116. Compared with connection methods such as bolt fasteners, this method has higher connection efficiency during mass production and is easier to ensure sealing performance.

[0103] In order to further improve the thermal conductivity between the phase change material 13 and the cleaning cloth 12, optionally, refer to Figure 3In an example of the cleaning component 10 of the present invention, the lower cover 116 is thermally connected to the rag 12, that is, the rag 12 is installed on the lower cover 116 and is thermally connected to the surface of the lower cover 116 on the side facing away from the upper cover 115. The thermal conductivity of the lower cover 116 is greater than the thermal conductivity 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, thereby achieving a thermal conductivity of the lower cover 116 greater than that of the upper cover 115. The upper cover 115 can also be made of ordinary plastic materials with low thermal conductivity such as polyethylene and polypropylene, while the lower cover 116 is a modified plastic material with high thermal conductivity to which metal materials are added, so that the thermal conductivity of the lower cover 116 can be greater than that of 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, on the one hand, the heat stored in the phase change material 13 to be quickly transferred to the rag 12 through the lower cover 116, heating the rag 12 and improving the heating efficiency and effect of the rag 12. On the other hand, it also reduces the heat transfer from the phase change material 13 in the sealed cavity 113 to the outside through the upper cover 115, thereby reducing the heat loss of the phase change material 13 and further improving the heating effect of the phase change material 13 on the rag 12.

[0104] In order to further reduce the heat transfer from the phase change material 13 to the outside through the upper cover 115, preferably, in an example of the cleaning component 10 of the present invention, refer to Figure 3, a rubber layer 1151 is provided on the side of the upper cover 115 facing away from the lower cover 116. The rubber layer 1151 can be applied to the entire upper surface of the upper cover 115, or it can be applied to a portion of the upper surface of the upper cover 115. By providing the rubber layer 1151 on the upper cover 115, and the thermal conductivity coefficient of the rubber layer 1151 is low, the exposed surface of the upper cover 115 can be covered and shielded, thereby reducing the heat exchange rate between the upper cover 115 and the surrounding air, and further reducing the heat transfer of 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 body 1152 and a second ring body 1153 coaxially arranged, and the first ring body 1152 and the second ring body 1153 both protrude toward the side facing away from the lower cover 116. The first ring body 1152 is on the outer periphery of the upper cover 115, and the second ring body 1153 is arranged between the connecting portion 14 and the first ring body 1152, and the second ring body 1153 is arranged close to the connecting portion 14. The rubber layer 1151 is applied to the surface of the second ring body 1153 on the side away from the lower cover 116. This arrangement can not only reduce the heat transfer from the phase change material 13 to the outside through the upper cover 115, but also because the position of the second ring body 1153 is close to the connecting portion 14, when the cleaning component 10 is installed, the second ring body 1153 will abut against the end face of the drive shaft of the drive component, and then when the cleaning component 10 needs to be disassembled, the rubber layer 1151 can also increase the friction between the end face of the drive shaft and the rag mounting bracket 11, thereby facilitating the disassembly of the cleaning component 10.

[0105] See also Figure 3In an example of the cleaning component 10 of the present invention, the lower cover 116 includes a heat-conducting rib 1161, and the heat-conducting rib 1161 at least partially extends to the interior of the sealed cavity 113. The material of the heat-conducting rib 1161 can be the same as that of the lower cover 116, for example, both are metal materials with good thermal conductivity, or both are plastic materials with good thermal conductivity, etc. The material of the heat-conducting member 322 can also be different from that of the lower cover 116, for example, the heat-conducting rib 1161 is made of metal, and the lower cover 116 is made of plastic, etc. The heat-conducting rib 1161 can be integrally formed and connected with the lower cover 116, or it can be assembled and connected in parts, etc., so as to meet the heat-conducting connection requirements between the heat-conducting rib 1161 and the lower cover 116. The shape of the heat-conducting rib 1161 in the sealed cavity 113 can be a plurality of triangular rib structures arranged at intervals, or it can be an integral annular thin-walled structure, or it can be a plurality of long rib structures arranged at intervals, etc. By providing heat-conducting ribs 1161 on the lower cover 116 and making the heat-conducting ribs 1161 at least partially extend into the interior of the sealed 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, thereby ensuring the hot mopping effect of the rag 12.

[0106] See also Figure 4 and Figure 5 In an example of the cleaning component 10 of the present invention, the rag 12 includes a fabric layer 121, a water-absorbing layer 122 and an adhesive layer 123 connected in sequence from bottom to top. The fabric layer 121, the water-absorbing layer 122 and the adhesive layer 123 can be connected by bonding, or by sewing, etc. Optionally, in this embodiment, the fabric layer 121, the water-absorbing layer 122 and the adhesive layer 123 are connected by sewing to form the rag 12. Suture connection has low cost and is simple and quick to operate. The fabric layer 121, the water-absorbing layer 122 and the adhesive layer 123 are coaxially arranged disc-shaped structures, and the outer diameters of the fabric layer 121, the water-absorbing layer 122 and the adhesive layer 123 are basically the same. A mounting hole 124 for connecting to the rag mounting frame 11 is provided in the central area of ​​the rag 12, and the mounting hole 124 passes through the fabric layer 121, the water-absorbing layer 122 and the adhesive layer 123 along the thickness direction of the rag 12. The fabric layer 121 is used for mopping the floor and absorbing stains. The fabric layer 121 can be any cloth that can be used for mopping, such as cotton cloth, fiber cloth or non-woven fabric. The water-absorbing layer 122 can be a sponge or a cotton cloth with good absorbency, so as to store some water in the rag 12 and realize wet mopping of the rag 12. Figure 4 and Figure 8The rag mounting frame 11 is provided with an adhesive portion 15 on the side facing the rag 12, and the adhesive layer 123 is configured to be bonded to the adhesive portion 15. The adhesive portion 15 may be an adhesive, and the adhesive layer 123 is bonded to the adhesive portion 15 by the adhesive to achieve a fixed connection between the rag mounting frame 11 and the rag 12. The adhesive portion 15 may also be an adhesive buckle, and the adhesive layer 123 may be a suede fabric that can be bonded to the adhesive buckle. The adhesive layer 123 is bonded to the adhesive buckle to achieve a fixed connection between the rag mounting frame 11 and the rag 12.

[0107] See also Figure 4 and Figure 5 , the phase change material 13 is arranged between the fabric layer 121 and the water-absorbing layer 122. The phase change material 13 can be sandwiched and fixed between the fabric layer 121 and the water-absorbing layer 122, or can be adhesively fixed to the fabric layer 121 or the water-absorbing layer 122. In another embodiment, the phase change material 13 can also be arranged between the water-absorbing layer 122 and the adhesive layer 123. In other embodiments, the phase change material 13 can also be partially arranged between the fabric layer 121 and the water-absorbing layer 122, and partially arranged between the water-absorbing layer 122 and the adhesive layer 123. It should be noted that the area where the phase change material 13 is arranged on the rag 12 not only needs to consider the heat storage requirements of the phase change material 13, but also needs to ensure the water absorption requirements of the water-absorbing layer 122, that is, the phase change material 13 cannot completely cover and block the water absorption surface of the water-absorbing layer 122, and some area needs to be reserved for the normal water absorption of the water-absorbing 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 capacity of the rag 12 and the heat storage requirement of the phase change material 13 .

[0108] By positioning the phase change material 13 between the fabric layer 121 and the water-absorbing layer 122 and / or between the water-absorbing layer 122 and the adhesive layer 123, the phase change material 13 can be completely immersed in the cleaning fluid during cleaning by the rag 12, thereby increasing the contact area between the phase change material 13 and the cleaning fluid and, in turn, improving the heat storage efficiency of the phase change material 13. Furthermore, when the rag 12 is cleaning, the heat conduction path between the phase change material 13 and the fabric layer 121 is shorter, thereby reducing heat loss during heat conduction from the phase change material 13 to the fabric layer 121. This further improves the heat conduction effect of the phase change material 13 on the fabric layer 121, thereby extending the hot mopping time of the fabric layer 121 and further enhancing the cleaning effect of the rag 12.

[0109] See also Figure 4 and Figure 5In an example of the cleaning component 10 of the present invention, the sum of the areas of the upper surface and the lower surface of the water-absorbing layer 122 is S1. The upper surface of the water-absorbing layer 122 refers to the surface of the water-absorbing layer 122 facing the adhesive layer 123, and the lower surface of the water-absorbing layer 122 refers to the surface of the water-absorbing layer 122 facing the fabric layer 121. The area S2 of the water-absorbing 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 provided only on the upper surface of the water-absorbing layer 122, or only on the lower surface of the water-absorbing layer 122, or the phase change material 13 can be provided at intervals on the upper surface or the lower surface, as long as it can be ensured that the area S2 of the water-absorbing 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 covers 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 covers 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-absorbing 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-absorbing 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, and the heat storage requirements of the phase change material 13 can be taken into account 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 the phase change material 13 from leaking in a liquid state, optionally, in an example of the cleaning component 10 of the present invention, a sealing interlayer (not shown in the figure) is provided between the fabric layer 121 and the water-absorbing layer 122, and the phase change material 13 is filled in the sealing interlayer. The sealing interlayer can be adhesively fixed to the water-absorbing layer 122 or the fabric layer 121, or it can be fixed between the fabric layer 121 and the water-absorbing layer 122 by sewing the water-absorbing layer 122 and the fabric layer 121. 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 water-absorbing layer 122, the sealing interlayer is a corresponding plurality of spaced interlayer units, each of which is filled with the phase change material 13. When the phase change material 13 covers the entire lower surface of the water absorbing layer 122 , the shape of the sealing interlayer is basically consistent with the shape of the water absorbing layer 122 , so that the phase change material 13 is filled in the sealing interlayer 16 so that the phase change material 13 covers the entire lower surface of the water absorbing layer 122 .

[0112] In another embodiment, a sealing interlayer may be provided between the water-absorbing layer 122 and the adhesive layer 123, and the phase change material 13 may be filled in the sealing interlayer. In this case, the phase change material 13 is provided on the upper surface of the water-absorbing layer 122. In other embodiments, a sealing interlayer may be provided between the water-absorbing layer 122 and the fabric layer 121, and a sealing interlayer may also be provided between the water-absorbing layer 122 and the adhesive layer 123. In this way, the upper and lower surfaces of the water-absorbing layer 122 may be provided with the phase change material 13 at the same time. It should be noted that when the phase change material 13 is a solid-solid phase change material, the phase change material 13 may also be provided in 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 rag 12 can also be facilitated, thereby reducing the difficulty of the installation process of the phase change material 13 on the rag 12.

[0113] Optionally, in an example of the cleaning assembly 10 of the present invention, please refer to Figure 6 , a microcapsule layer 17 is provided on the upper surface of the water-absorbing layer 122, and the microcapsule layer 17 includes a plurality of microcapsules, and the microcapsules are filled with phase change material 13. The size and number of the microcapsules in the microcapsule layer 17 need to be determined according to various factors such as the material properties of the phase change material 13 or the difficulty of filling. The microcapsule layer 17 can be applied to the upper surface of the water-absorbing layer 122 by coating technology, or it can be adhered to the upper surface of the water-absorbing layer 122 by an adhesive, etc. Preferably, in this embodiment, the microcapsule layer 17 is applied to the upper surface of the water-absorbing layer 122. In this way, a relatively uniform distribution of microcapsules can be obtained. The microcapsule layer 17 can be a layer covering the entire upper surface of the water-absorbing layer 122, or it can be a plurality of microcapsule layers 17 spaced apart on the upper surface of the water-absorbing layer 122, so as to meet the heat storage requirements of the phase change material 13 and the water absorption performance of the water-absorbing layer 122.

[0114] In another embodiment, a microcapsule layer 17 may be provided on the lower surface of the water-absorbing layer 122. In other embodiments, a microcapsule layer 17 may be provided on the upper surface of the water-absorbing layer 122, and a microcapsule layer 17 may also be provided on the lower surface of the water-absorbing layer 122. By providing the microcapsule layer 17 on the water-absorbing layer 122 and filling the microcapsules with the 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 to overflow from the sutured pores of the rag 12, which is more conducive to retaining the phase change material 13 inside the rag 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 facilitating the improvement of the heat storage efficiency of the phase change material 13.

[0115] See also Figure 5 and Figure 6In an example of the cleaning component 10 of the present invention, the upper surface of the water-absorbing layer 122 is coated with a plurality of first microcapsule layers 171 spaced apart, and the lower surface of the water-absorbing layer 122 is coated with a plurality of second microcapsule layers 172 spaced apart, and the plurality of first microcapsule layers 171 and the plurality of second microcapsule layers 172 are staggered up and down. It should be noted that the staggered 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 rag 12 partially overlap, and partially do not overlap. Figure 6 There are many ways to stagger the multiple first microcapsule layers 171 and the multiple second microcapsule layers 172 up and down. In this embodiment, the multiple first microcapsule layers 171 are spaced apart in a fan-shaped structure along the circumferential direction of the water-absorbing layer 122, and the multiple second microcapsule layers 172 are also spaced apart in a fan-shaped structure along the circumferential direction of the water-absorbing layer 122. In the circumferential direction of the water-absorbing layer 122, the first microcapsule layers 171 and the second microcapsule layers 172 are staggered up and down along the circumferential direction. In other embodiments, the multiple first microcapsule layers 171 can be spaced apart in a plurality of annular shapes along the radial direction of the water-absorbing layer 122, and the multiple second microcapsule layers 172 can be spaced apart in a plurality of annular shapes along the radial direction of the water-absorbing layer 122. In the radial direction of the water-absorbing layer 122, the first microcapsule layers 171 and the second microcapsule layers 172 are staggered up and down along the radial direction.

[0116] By staggering the plurality of first microcapsule layers 171 and the plurality of second microcapsule layers 172 up and down, this arrangement can, on the one hand, increase the arrangement area of ​​the microcapsule layer 17 on the water-absorbing layer 122 as much as possible while ensuring the water absorption performance requirements of the water-absorbing layer 122, thereby increasing the amount of phase change material 13 used to ensure the heat storage performance of the phase change material 13 and the thermal conductivity to the fabric layer 121. On the other hand, since the first microcapsule layer 171 and the second microcapsule layer 172 are arranged in an alternating manner, during the mopping process, when the rag 12 is replenished with water, the water flow will enter from the upper surface of the water-absorbing layer 122, bypass the interlaced position of the first microcapsule layer 171 and the second microcapsule, and then flow from the lower surface of the water-absorbing layer 122 to the fabric layer 121. Therefore, the flow path length of the water flow in the water-absorbing layer 122 can be increased, the residence time of the water flow in the rag 12 can be extended, and the contact time of the water flow with the phase change material 13 can be increased, thereby increasing the outlet water temperature of the water flow, thereby improving the hot mopping effect of the rag 12.

[0117] See also Figure 7 and Figure 8In one example of the cleaning component 10 of the present invention, the phase change material 13 is a solid-solid phase change material, and the rag mounting frame 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 use strength and hardness requirements of the rag mounting frame 11 during the phase change process. The rag mounting frame 11 can be made entirely of the phase change material 13, or the portion of the rag mounting frame 11 that contacts the rag 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 rag 12 are met. This arrangement can achieve direct contact between the phase change material 13 and the rag 12, thereby reducing the thermal conductivity path between the phase change material 13 and the rag 12 and further improving the heating effect of the phase change material 13 on the rag 12. At the same time, there is no need to additionally set the phase change material 13 on the rag mounting frame 11, so the mass of the rag mounting frame 11 itself can be reduced, which is conducive to the lightweight design of the rag mounting frame 11.

[0118] If the phase change material 13 is a solid-solid phase change material, optionally, in one example of the cleaning assembly 10 of the present invention, the entire rag mounting frame 11 is injection molded from the phase change material 13. That is, the entire rag mounting frame 11 is composed entirely of the phase change material 13. This arrangement allows for a large area and mass of phase change material 13 to be formed on the rag mounting frame 11. Furthermore, during the cleaning process of the rag 12, the contact area between the phase change material 13 and the cleaning fluid can be increased, thereby improving the heat storage efficiency and energy of the phase change material 13. This can extend the heat conduction time of the phase change material 13 to the rag 12 during the cleaning operation, further enhancing the thermal mopping effect of the rag 12.

[0119] Under the condition that the phase change material 13 is a solid-solid phase change material, optionally, in an example of the cleaning component 10 of the present invention, refer to Figure 8The rag mounting frame 11 includes a main body 117. The material of the main body 117 can be plastic or metal, depending on the support requirements of the rag mounting frame 11. The side of the main body 117 facing the rag 12 includes a phase change material 13, and the phase change material 13 is at least partially in contact with the rag 12. The phase change material 13 can be integrally connected to the main body 117 by hot melt, or can be adhesively connected, or can be fixed by bolts and other connection methods. The phase change material 13 can be a disc-shaped structure that matches the shape of the rag 12, or it can be a plurality of local block structures arranged at intervals. In order to obtain a larger area of ​​the phase change material 13 and increase the contact area between the phase change material 13 and the rag 12, preferably, in this embodiment, the phase change material 13 is an annular structure that matches the shape of the rag 12, that is, the shape of the phase change material 13 facing the rag 12 is roughly the same as the shape of the rag 12. The phase change material 13 and the rag 12 can be bonded together by an adhesive or by an adhesive buckle 16. Optionally, to facilitate assembly and disassembly between the rag 12 and the rag mounting frame 11, in this embodiment, an adhesive buckle 16 is installed on the side of the phase change material 13 facing the rag 12, and the side of the rag 12 facing the phase change material 13 is made of suede fabric. The suede fabric and the adhesive buckle 16 are bonded together to achieve a fixed connection between the rag 12 and the rag mounting frame 11.

[0120] By disposing the phase change material 13 on the side of the main body facing the rag 12, the main body 117 and the phase change material 13 can be separated. Furthermore, by selecting an appropriate material for the main body 117, the supporting strength of the rag mounting frame 11 itself can be ensured, thereby reducing the impact of the phase change material 13 on the supporting strength of the rag mounting frame 11. This facilitates the selection of materials for the phase change material 13. Furthermore, because the main body 117 covers the surface of the phase change material 13 facing away from the rag 12, selecting a material with a lower thermal conductivity for the main body can also enhance the thermal insulation effect of the phase change material 13, reduce heat loss from the phase change material 13 to the outside, and improve the heating effect and heating time of the phase change material 13 on the rag 12.

[0121] In an example of the cleaning assembly 10 of the present invention, provided that the phase change material 13 is a solid-solid phase change material, the rag mounting frame 11 includes a main body 117 made of a metal material, with the phase change material 13 surrounding the main body 117. It should be noted that the metal material in this embodiment refers to a metal material having a certain degree of support strength and rigidity, such as aluminum, carbon steel, stainless steel, etc. The phase change material 13 surrounding the main body 117 can mean that the exposed surface of the metal material is completely surrounded by the phase change material 13, or it can mean that a portion of the metal material is surrounded by the phase change material 13, such as the side of the metal material facing the rag 12. By providing the main body 117 of metal material and allowing the phase change material 13 to surround the metal material, the metal main body 117 can provide better support, thereby improving the support strength of the rag mounting frame 11. Furthermore, because the phase change material 13 surrounds the metal material, the metal material can provide better support for the phase change material 13, thereby reducing the difficulty in selecting the phase change material 13. Furthermore, wrapping the phase change material 13 outside the main body 117 can also increase the amount of phase change material 13 used, which is beneficial to improving the heat storage performance of the phase change material 13 and thereby improving the heating effect of the phase change material 13 on the rag 12 .

[0122] See also Figure 10 and Figure 11 The present invention further provides a cleaning system 30, which includes the cleaning device 20 and the base station 31 in the above example. The base station 31 includes a base station body 315 and a base 311. The base 311 is arranged at the lower end of the base station body 315. There is a accommodating cavity 3112 for accommodating the cleaning device 20 between the base 311 and the base station body 315. The base 311 is provided with a cleaning tank 312 for accommodating cleaning liquid. The cleaning tank 312 is located at the bottom of the accommodating cavity 3112, and the cleaning tank 312 can accommodate the cleaning component 10 on the cleaning device 20. The cleaning liquid is accommodated in the cleaning tank 312. The shape and number of the cleaning tanks 312 correspond to the shape and number of the rags 12 on the cleaning component 10. Preferably, in this embodiment, two cleaning tanks 312 are provided, and the two cleaning tanks 312 are symmetrically installed at the bottom of the accommodating cavity 3112. The cleaning device 20 is provided with two cleaning assemblies 10. After returning to the base station 31, the cleaning device 20 enters the accommodating chamber 3112 and allows the rag 12 on the cleaning assembly 10 to enter 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 existing base stations 31, such as an energy system, a negative pressure suction system, a sewage tank, and a clean water tank, which will not be detailed here.

[0123] See also Figure 12 and Figure 14The cleaning tank 312 is equipped with a heating device 32 for heating the cleaning liquid. In the prior art, instant heating components are typically installed in the water path of the base station 31 for heating. Over time, scale easily accumulates within the instant heating components, making maintenance difficult. In contrast, the heating device 32 in this solution directly heats the cleaning liquid within the cleaning tank 312 of the base station 31. This arrangement prevents scale from forming within the cleaning tank 312. Even if scale does form, the cleaning tank 312 is easily maintained, for example, by disassembling the cleaning tank 312 for cleaning.

[0124] Specifically, the heating device 32 can be provided at any position of the cleaning tank 312, such as the bottom wall, side wall, etc. of the cleaning tank 312, as long as it can heat the cleaning liquid. The specific structure of the heating device 32 can be an electric heating wire heating module, an electric heating plate heating module, a phase change material heating module, etc. The heating method of the heating device 32 for heating the cleaning liquid is not limited. For example, it can directly heat the cleaning liquid in the cleaning disk, or it can first heat the cleaning liquid entering the cleaning disk so that the heated cleaning liquid is directly passed into the cleaning disk. Since the heating device 32 is provided in the cleaning tank 312, the distance between the heating device 32 and the cleaning tank 312 can be shortened, thereby reducing the heat lost during the transportation of the cleaning liquid, which is beneficial to improving the heating efficiency of the cleaning liquid and playing a role in energy conservation and emission reduction.

[0125] When the cleaning device 20 completes a cleaning operation and returns to the base station 31, the cleaning assembly 10 is placed in the cleaning tank 312, and the rag 12 comes into contact with the cleaning liquid in the cleaning tank 312. If the rag 12 requires hot water cleaning, the heating device 32 is operated to heat the cleaning liquid. The rag 12 is then cleaned in the heated cleaning liquid. At this time, the phase change material 13 on the cleaning assembly 10 absorbs the heat from the cleaning liquid and stores it. When the rag 12 completes the cleaning operation, the cleaning device 20 leaves the base station 31 and continues cleaning the floor. At this time, the phase change material 13 releases heat and transfers it to the rag 12, allowing the rag 12 to replenish its heat, thereby extending the time the rag 12 can mop the floor with hot water and improving the cleaning effect of the rag 12.

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

[0127] See also Figure 10 and Figure 12 In an example of the cleaning system 30 of the present invention, the accommodating chamber 3112 is provided with a passage opening 3111 for the cleaning device 20 to enter and exit. The cleaning tank 312 includes a front tank portion 3121 provided near the passage opening 3111 and a rear tank portion 3122 provided away from the passage 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. The heating device 32 is provided in the front tank portion 3121, as shown in FIG. Figure 14 As shown. The heating device 32 can be a part of the bottom wall of the front groove portion 3121, or it can be a separate heating element provided on the side of the bottom wall of the front groove portion 3121 facing the ground, and heats the bottom wall of the front groove portion 3121 by thermally connecting with the bottom wall of the front groove portion 3121. Optionally, in this embodiment, a mounting cavity 314 is provided on the side of the bottom wall of the front groove portion 3121 facing the ground, and the heating device 32 is provided in the mounting cavity 314. For details, please refer to Figure 12 and Figure 14 The heating device 32 includes a heating tube 321 and a heat conductor 322. The heat conductor 322 forms the bottom wall of the front groove portion 3121. The heat conductor 322 is thermally connected to the heating tube 321, thereby enabling the heating device 32 to heat the front groove portion 3121. Furthermore, a cover plate 313 is provided at the opening of the installation cavity 314. The cover plate 313 covers the installation cavity 314 to reduce heat conduction from the heating device 32 to the ground and protect the heating device 32. By making the bottom wall height of the front groove portion 3121 lower than the bottom wall height of the rear groove portion 3122 and arranging the heating device 32 in the front groove portion 3121, more cleaning liquid can be stored in the front groove portion 3121, thereby making the heating device 32 have a better heating effect on the cleaning liquid and a higher heating efficiency.

[0128] See also Figure 10 、 Figure 12 and Figure 13In one example of the cleaning system 30 of the present invention, the base station 31 includes a liquid supply pipeline (not shown). A water spray hole 3123 is provided in the cleaning tank 312. The water spray hole 3123 is connected to the liquid supply pipeline, and the cleaning liquid enters the cleaning tank 312 through the water spray hole 3123 through the liquid supply pipeline. The bottom wall of the cleaning tank 312 is provided with a protrusion 3124, which divides the cleaning tank 312 into a front tank portion 3121 and a rear tank portion 3122. The protrusion 3124 extends in the radial direction of the cleaning tank 312. A cleaning rib 3125 is provided at one end of the protrusion 3124. The cleaning rib 3125 is a long strip-shaped protrusion structure extending from the center of the cleaning tank 312 to one side in the radial direction of the cleaning tank 312. The other end of the protrusion 3124 is provided with a water spray hole 3123. There are multiple water spray holes 3123 arranged along the length of the protrusion 3124, and the water spray direction of the water spray holes 3123 is inclined toward the side of the front groove portion 3121, so that the water drop point of the water spray holes 3123 is located at the bottom wall of the front groove portion 3121. With this arrangement, when the cleaning tank 312 is accidentally bumped or needs to be moved, the water spray holes 3123 can spray water to the front groove portion 3121 in time to cool the front groove portion 3121 and reduce burns to surrounding objects or personnel. It should be noted that when the cleaning component 10 is not working, the instant heating component and the heating device 32 in the base station 31 usually stop heating. Then, when the cleaning tank 312 is accidentally bumped or moved, the water spray holes 3123 will spray cold water with a lower temperature to achieve the effect of cooling the front groove portion 3121.

[0129] In an example of the cleaning system 30 of the present invention, the base station 31 includes a liquid supply pipeline connected to the cleaning tank 312 . A heating component is provided on the liquid supply pipeline to heat the cleaning liquid. The outlet of the heating component is connected to the cleaning tank 312 .

[0130] With this arrangement, the cleaning liquid in the cleaning tank 312 can be preheated by the instant heating component and then heated by the heating device 32. Therefore, the cleaning liquid in the cleaning tank 312 can be heated twice, which can improve the heating efficiency of the cleaning liquid by the heating device 32. At the same time, it can also reduce the heating temperature of the cleaning liquid by the instant heating component, thereby reducing the probability of scale residue inside the instant heating component due to excessive temperature and reducing the maintenance frequency of the instant heating component. The cleaning component of the present invention is provided with a phase change material. During the cleaning operation, the cleaning component can heat the rag through the phase change material to achieve hot mopping of the rag, thereby improving the cleaning effect of the cleaning component on the ground. At the same time, because the phase change material has a high energy density, it can absorb or release a large amount of heat during the phase change process and can store a large amount of thermal energy in a relatively small volume or mass. Therefore, it can save the installation space occupied by the cleaning component and reduce the overall quality of the cleaning component. In addition, since the phase change material only needs to absorb the cleaning liquid or the heat of the heating element that heats the cleaning liquid when the rag is cleaning, and there is no need to set up an additional heat source for the cleaning component, the structure is safer, simpler and more energy-efficient.

[0131] Therefore, the present invention effectively overcomes some practical problems in the prior art and thus has high utility value and practical significance. The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons of ordinary skill in the art without departing from the spirit and technical concepts disclosed in the present invention shall be covered by the claims of the present invention.
