[0051] See also Figures 1 to 17 The utility model provides a cleaning device 10, a cleaning system 20 and a cleaning component 12. The cleaning device 10 is provided with a heat storage device 13 on the cleaning component 12, and the heat storage device 13 is thermally connected to the rag 122. During the cleaning process, the heat storage device 13 can heat the rag 122 to achieve hot mopping of the rag 122, which is beneficial for removing stubborn stains, oil stains, etc. on the ground, thereby improving the cleaning effect.

[0052] See also Figures 1 to 8 The cleaning device 10 includes: a body 11, a cleaning component 12 and a heat storage device 13.

[0053] The interior of the body 11 has a storage space for accommodating the various components of the cleaning device 10. The shape of the body 11 can be any shape, for example, the shape of the body 11 can be circular, oval, or D-shaped, among other shapes. The cleaning assembly 12 also includes a drive assembly conventionally provided on existing cleaning devices 10. The drive assembly is disposed below the body 11 to drive the cleaning device 10 to achieve self-propelled movement. The specific structure of the drive assembly and the connection structure between the drive assembly and the body 11 can be referred to the relevant structural description of the existing cleaning device 10 and will not be repeated here.

[0054] The cleaning assembly 12 can be detachably connected to the body 11. The detachable connection method can be a snap-on detachable connection, a bolted detachable connection, etc. The cleaning assembly 12 is configured for wet mopping. The body 11 is provided with a water supply mechanism (not shown in the figure). The water outlet of the water supply mechanism is connected to the rag 122 to provide liquid to the rag 122 on the cleaning assembly 12. The liquid can be cleaning liquid or ordinary tap water, etc., which is determined by the wet mopping requirements of the cleaning device 10. Please refer to Figures 10 to 12 The cleaning device 10 is correspondingly configured with a base station 21, which is provided with a cleaning assembly. The cleaning assembly can be an existing cleaning tank structure or any other structure capable of containing cleaning liquid and capable of cleaning the rag 122. During the cleaning operation, the cleaning device 10 can return to the base station 21 multiple times to clean the cleaning assembly 12. The base station 21 is provided with a heating device 22, which can heat the cleaning liquid contained in the cleaning assembly 12, achieving thermal cleaning of the rag 122 in the cleaning assembly 12, thereby enhancing the cleaning effect of the cleaning assembly 12.

[0055] See also Figures 1 to 3 The cleaning component 12 includes a rag mounting frame 121 and a rag 122. The rag mounting frame 121 is installed below the body 11, and the rag 122 is set on the rag mounting frame 121. The rag mounting frame 121 and the rag 122 can be detachably connected or fixedly connected. The rag mounting frame 121 and the body 11 can be detachably connected or fixedly connected. When replacing the rag 122, the rag 122 can be directly removed from the rag mounting frame 121 to replace the rag 122, or the rag 122 can be removed together with the rag mounting frame 121 to replace the rag 122. The rag 122 can be a round rag, a rectangular rag, a polygonal rag, etc. In this embodiment, for the convenience of description, the rag 122 is a round rag. A round rag means that the cleaning working surface between the rag 122 and the ground has a circular outline. The number of cleaning components 12 can be one or more, depending on the cleaning area and cleaning efficiency requirements of the cleaning device 10. In this embodiment, two groups of cleaning components 12 are provided, and the two groups of cleaning components 12 are symmetrically installed at the bottom of the body 11 to achieve floor cleaning operations while the cleaning device 10 is moving.

[0056] See also Figures 4 to 7 In this embodiment, the heat storage device 13 is thermally connected to the rag 122. As long as the heat storage device 13 and the rag 122 are thermally connected, the installation position of the heat storage device 13 is not limited. For example, the heat storage device 13 can be set on the rag 122, that is, the heat storage device 13 is directly in contact with and fixedly connected to the rag 122 to achieve a thermal connection between the heat storage device 13 and the rag 122; the heat storage device 13 can also be set on the rag mounting frame 121, that is, the heat storage device 13 is indirectly in contact with the rag 122 through the rag mounting frame 121 to achieve a thermal connection; the heat storage device 13 can also be set between the rag mounting frame 121 and the rag 122, that is, the heat storage device 13 can be connected to the rag 122 and the rag mounting frame 121 at the same time. When the rag 122 is cleaning, the heat storage device 13 absorbs heat from the heat source to store heat; when the rag 122 is cleaning, the heat storage device 13 releases heat to the rag 122 to conduct heat to the rag 122. The heat source in this embodiment can be a cleaning liquid, a heating element for heating the cleaning liquid, or a combination of a cleaning liquid and a heating element. By providing the heat storage device 13, the cleaning device 10 can heat the rag 122 through the heat storage device 13 during the cleaning process, thereby achieving hot mopping of the rag 122, thereby improving the cleaning effect of the cleaning device 10 on the floor. At the same time, since the heat storage device 13 only needs to absorb the heat of the cleaning liquid or the heating element for heating the cleaning liquid when the rag 122 is cleaning, and there is no need to provide an additional heat source for the cleaning component 12, the structure of this solution is safer, more compact and energy-saving compared to the solution of directly providing a heating module on the body 11.

[0057] There are many options for the structure of the heat storage device 13. The heat storage device 13 can be a structure containing a phase change material. The phase change material can undergo a phase change within a certain temperature range, such as from solid to liquid or from liquid to solid. When the phase change material changes from solid to liquid, it absorbs heat; when the phase change material changes from liquid to solid, it releases heat. The conversion of the heat storage device 13 between heat absorption and heat release is achieved through the state change of the phase change material. The heat storage device 13 can also be a structure containing a solid medium, such as a structure made of heat-absorbing materials such as stone, ceramic or metal; the heat storage device 13 can also be a structure containing a liquid medium, such as water, liquid metal, or any other structure that can absorb the heat of the cleaning liquid when the rag 122 is cleaning, and release heat to the rag 122 when the rag 122 is performing the cleaning operation. The specific structure of the heat storage device 13 needs to be determined based on various conditions such as the heat storage energy requirements and the operating temperature of the rag 122. By providing a heat storage device 13 on the cleaning assembly 12, and thermally connecting the heat storage device 13 to the rag 122, the heat storage device 13 absorbs the heat of the cleaning fluid when the rag 122 is cleaning, and releases the heat to the rag 122 when the rag 122 is cleaning. In this way, when the rag 122 is cleaning, the heat storage device 13 can transfer heat to the rag 122, thereby reducing the rate of temperature drop of the rag 122, increasing the time that the rag 122 can maintain hot water mopping, and ultimately improving the cleaning effect of the cleaning assembly 12 when mopping the floor with hot water. At the same time, because the heat storage device 13 can absorb the heat of the cleaning fluid when the rag 122 is cleaning, there is no need to provide an additional heating source for the cleaning assembly 12, resulting in a simple structure and easy implementation.

[0058] Considering the heat conduction effect between the heat storage device 13 and the rag 122, preferably, in an example of the cleaning device 10 of the present invention, refer to Figures 5 to 7, along the height direction of the cleaning component 12, the heat storage device 13 is clamped between the rag 122 and the rag mounting frame 121. The heat storage device 13 can be clamped and fixed only by the clamping force between the rag 122 and the rag mounting frame 121, or it can be installed and fixed between the rag 122 and the rag mounting frame 121 by bonding or bolting. By clamping the heat storage device 13 between the rag 122 and the rag mounting frame 121, not only can a larger heat conduction area be obtained between the heat storage device 13 and the rag 122, thereby improving the heat conduction efficiency between the heat storage device 13 and the rag 122, but the clamping force generated by the rag mounting frame 121 and the rag 122 on the heat storage device 13 can also improve the fit between the heat storage device 13 and the rag 122, further improving the heat conduction efficiency between the heat storage device 13 and the rag 122. It should be noted that, in other embodiments, the heat storage device 13 may also be arranged on the rag mounting frame 121, for example, on the side surface of the rag mounting frame 121 facing away from the rag 122. The heat storage device 13 absorbs the heat of the cleaning liquid during the cleaning process of the rag 122 through heat conduction between the rag mounting frame 121 and the rag 122, and releases heat to the mop 122 during the cleaning operation.

[0059] When the heat storage device 13 is in contact with the rag 122 and the rag mounting frame 121 at the same time, part of the heat of the heat storage device 13 will be transferred to the air through the rag mounting frame 121, causing the heat of the heat storage device 13 to be lost, which in turn will lead to a decrease in the amount of heat transferred from the heat storage device 13 to the rag 122. In view of this, in an example of the cleaning device 10 of the present invention, the rag mounting frame 121 is made of a heat-insulating material. The heat-insulating material can be any heat-insulating material with a certain hardness and support strength, such as polyurethane or polystyrene. By setting the rag mounting frame 121 to be a heat-insulating material, the heat dissipated by the heat storage device 13 through the rag mounting frame 121 can be reduced, thereby relatively increasing the amount of heat transferred from the heat storage device 13 to the rag 122, which is conducive to slowing down the temperature drop rate of the rag 122 during operation. At the same time, it can also prevent the temperature of the body 11 from rising, which would lead to poor heat dissipation of the body 11 and affect the normal operation of the body 11.

[0060] See also Figure 6In an example of the cleaning device 10 of the present invention, a groove 1211 is provided on the side of the rag mounting frame 121 facing the rag 122, and the rag 122 is blocked at the opening of the groove 1211. The heat storage device 13 is accommodated in the groove 1211, and the surface of the heat storage device 13 facing the rag 122 is at least partially in contact with the rag 122. The groove 1211 can be a circular ring structure arranged in the circumferential direction around the rag 122, or it can be a plurality of local grooves 1211 structures arranged at intervals above the rag 122. The cross-section of the groove 1211 can be any shape such as a rectangle, a triangle or a V-shape, whichever is greater, so long as it can accommodate the heat storage device 13. It should be noted that the rag 122 blocking the opening of the groove 1211 means that the surface of the side of the rag 122 facing the groove 1211 abuts against the opening of the groove 1211 to form a blocking relationship, and it does not necessarily mean that the rag 122 seals the opening of the groove 1211. By providing the groove 1211 and placing the heat storage device 13 in the groove 1211 , the probability of the heat storage device 13 contacting the outside air can be reduced, and the heat lost by the heat storage device 13 to the air can be further reduced, thereby further increasing the heat conducted by the heat storage device 13 to the rag 122 .

[0061] See also Figure 3 and Figure 7 In an example of the cleaning device 10 of the present invention, the cleaning component 12 also includes a heat conductor 14, which is arranged at the opening of the groove 1211, and the upper and lower sides of the heat conductor 14 are in contact with the heat storage device 13 and the rag 122 respectively. The heat conductor 14 can be clamped and fixed at the opening of the groove 1211 by the clamping force between the rag 122 and the groove 1211, or it can be directly fixedly connected to the groove 1211 or the rag 122, as long as the heat conductor 14 can be clamped between the heat storage device 13 and the rag 122 so that the two sides of the heat conductor 14 are in contact with the heat storage device 13 and the rag 122 respectively. The heat conductor 14 can be of any shape, such as a disc, an annular ring, a polygon, etc. The heat conductor 14 can be made of metal, such as aluminum, copper, etc., or it can be made of graphite, ceramic, etc., as long as the thermal conductivity requirements between the heat storage device 13 and the rag 122 are met. By providing a heat conducting member 14, the heat conduction efficiency between the heat storage device 13 and the rag 122 can be improved. At the same time, the thermal conductivity of the heat conducting member 14 can be adjusted by selecting materials with different thermal conductivities to adjust the heat transfer efficiency between the heat storage device 13 and the rag 122, so that the heat storage device 13 can better adapt to the different operating temperature requirements of the rag 122.

[0062] Considering the uniformity of heat conduction between the heat storage device 13 and the rag 122, preferably, in an example of the cleaning device 10 of the present invention, refer to Figures 7 to 9, the heat storage device 13 is a circular ring structure, and the heat storage device 13 is coaxially arranged with the rag 122. The outer diameter of the heat storage device 13 can be greater than the outer diameter of the rag 122, or less than or equal to the outer diameter of the rag 122. As long as a circular heat conduction surface is formed between the heat storage device 13 and the rag 122 to meet the heat conduction requirements of the rag 122 and the heat storage device 13, the specific area and size of the heat storage device 13 are not limited in this embodiment. Preferably, in one embodiment of the present utility model, the outer diameter of the heat storage device 13 is smaller than the outer diameter of the rag 122. This arrangement can reduce the heat loss caused by the heat storage device 13 transferring heat to the rag 122, and can also reduce the probability of the heat storage device 13 colliding with external obstacles during the cleaning operation of the rag 122.

[0063] By configuring the heat storage device 13 as a circular ring structure and configuring the heat storage device 13 coaxially with the rag 122, a circular heat conduction surface can be formed between the side of the heat storage device 13 facing the rag 122 and the rag 122, so that the rag 122 can receive relatively uniform heat in the circumferential direction, thereby improving the uniformity of the heating of the rag 122 in the circumferential direction, and thus helping to improve the consistency of the cleaning effect of the rag 122 in the working area. At the same time, the coaxial configuration of the heat storage device 13 and the rag 122 can also facilitate the positioning and installation between the heat storage device 13 and the rag 122. It should be noted that when the heat storage device 13 is installed in the groove 1211, the groove 1211 needs to be configured as a circular groove structure corresponding to the heat storage device 13.

[0064] In an example of the cleaning device 10 of the present invention, the heat storage device 13 includes a phase change material. The heat storage device 13 may be entirely phase change material, or part of it may be phase change material and part of it may be other heat storage materials. The phase change material may be an organic phase change material, such as paraffin, acetic acid, etc., or an inorganic phase change material, such as molten salts, metals or alloys, etc. The specific choice of phase change material is determined by the heat conduction requirements between the heat storage device 13 and the rag 122. Preferably, in this embodiment, the heat storage device 13 is entirely phase change material. 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 heat energy in a relatively small volume or mass, so that the installation space of the heat storage device 13 can be saved and the overall mass of the cleaning component 12 can be reduced. It should be noted that the heat storage device 13 may include only phase change material, or it may also include a heat-conducting shell, and the phase change material is installed in the heat-conducting shell.

[0065] In an example of the cleaning device 10 of the present invention, please refer to Figure 7 and Figure 8, the heat-conducting member 14 is sealed at the opening of the groove 1211, so that a sealed cavity for accommodating the heat storage device 13 is formed between the groove 1211 and the heat-conducting member 14. There are many ways for the heat-conducting member 14 to seal the opening of the groove 1211, such as adhesive sealing, welding connection or thermoplastic sealing. By forming a sealed cavity between the groove 1211 and the heat-conducting member 14, the heat storage device 13 can be accommodated in the sealed cavity, which can reduce the probability of the cleaning liquid entering the interior of the groove 1211 and causing rust to the internal parts when the rag 122 is used for cleaning. At the same time, when the heat storage device 13 is a phase change material, the phase change material can be directly accommodated in the sealed cavity, and there is no need to additionally set other sealed shells on the outside of the phase change material. This can simplify the number of installed parts and is conducive to reducing the assembly cost of the cleaning equipment 10.

[0066] In an example of the cleaning device 10 of the present invention, please refer to Figure 7 and Figure 8 , along the radial direction of the rag 122, the groove 1211 is respectively provided with an outer stop ring 1212 and an inner stop ring 1213 at the opening position. The outer stop ring 1212 and the inner stop ring 1213 can be located at the same height, or they can form a certain height difference with each other. The outer stop ring 1212 and the inner stop ring 1213 can be coaxially arranged, or they can be non-coaxially arranged. The outer stop ring 1212 and the inner stop ring 1213 can extend in a plane along the radial direction of the rag 122, or they can extend in an inclined manner. Preferably, in this embodiment, in order to facilitate the molding process of the groove 1211, the outer stop ring 1212 and the inner stop ring 1213 are arranged at the same height, and both extend in a plane along the radial direction of the rag 122. The heat conductor 14 is a circular ring structure. Along the radial direction of the heat conductor 14, the heat conductor 14 includes an outer peripheral edge 141 and an inner peripheral edge 142. The outer peripheral edge 141 overlaps the upper surface of the outer stop ring 1212, and forms a first annular contact surface 143 at the outer peripheral edge 141; the inner peripheral edge 142 overlaps the upper surface of the inner stop ring 1213, and forms a second annular contact surface 144 at the inner peripheral edge 142. The area of the first annular contact surface 143 and the second annular contact surface 144 is not limited, as long as they can bear the weight of the heat conductor 14 without causing significant deformation in the height direction. By forming an annular contact surface between the heat conductor 14 and the groove 1211, the axial positioning of the heat conductor 14 on the groove 1211 can be facilitated, and the sealed connection between the heat conductor 14 and the opening of the groove 1211 can also be facilitated.

[0067] In an example of the cleaning device 10 of the present invention, please refer to Figure 7 and Figure 8The heat conducting member 14 is provided with a protrusion 145 between the outer peripheral edge 141 and the inner peripheral edge 142. The protrusion 145 protrudes toward the side of the rag 122, and the heat storage device 13 is at least partially in contact with the surface of the protrusion 145 on the side facing away from the rag 122. The protrusion 145 can be a circular ring structure surrounding the circumference of the heat conducting member 14, or it can be a plurality of local protrusion structures arranged at intervals. Preferably, in this embodiment, the protrusion 145 is a circular ring structure arranged coaxially with the groove 1211. By providing the protrusion 145, a corresponding cavity area can be formed on the side of the protrusion 145 facing away from the rag 122, which can relatively increase the accommodation space of the heat storage device 13 inside the groove 1211, thereby facilitating the improvement of the heat storage capacity of the heat storage device 13. Along the radial direction of the rag 122, the radial width of the protrusion 145 corresponds to the opening width of the groove 1211, that is, the protrusion 145 is snapped into place at the opening of the groove 1211 in the radial direction. With this arrangement, when the heat conductor 14 and the groove 1211 are installed, the protrusion 145 can play a role in radial positioning, which facilitates the positioning and installation of the heat conductor 14 and the groove 1211, and forms a radial stop between the heat conductor 14 and the groove 1211, reducing the probability of radial displacement of the heat conductor 14 relative to the groove 1211 during the cleaning operation.

[0068] In one example of the cleaning device 10 of the present invention, the temperature reached by the heat storage device 13 after absorbing the heat from the cleaning fluid is any value within the range of 25°C to 200°C, such as 25°C, 100°C, or 200°C. Limiting the temperature reached by the heat storage device 13 after absorbing the heat from the cleaning fluid to the range of 25°C to 200°C allows the rag 122 to maintain an optimal temperature during cleaning operations, meeting various conventional floor cleaning requirements and achieving optimal cleaning results.

[0069] In one example of the cleaning device 10 of the present invention, the rag mounting frame 121 and the heat storage device 13 include a connected hollow area 15. The water replenishment mechanism is provided with a water outlet. When the cleaning assembly 12 is installed on the body 11, the water outlet is connected to the hollow area 15. When the liquid in the water replenishment mechanism is discharged from the water outlet, it passes through the hollow area 15 and enters the rag 122, thereby replenishing the liquid in the rag 122 and enabling the rag 122 to wet mop the floor. By providing the hollow area 15, during the cleaning process of the rag 122, the water replenishment mechanism can replenish the liquid in the water replenishment mechanism to the rag 122, allowing the liquid in the water replenishment mechanism to enter the rag 122, thereby achieving wet mopping during the cleaning operation of the rag 122, thereby improving the cleaning effect of the cleaning device 10.

[0070] The present invention also provides a cleaning system 20, see Figures 10 to 12, the cleaning system 20 includes the cleaning device 10 and the base station 21 in any of the above examples. The base station 21 includes a main body 201 and a base 211, and the base 211 is arranged at the lower end of the main body 201. There is a accommodating cavity for accommodating the cleaning device 10 between the base 211 and the main body 201. The base 211 is provided with a cleaning tank 212 for accommodating cleaning liquid, and the cleaning tank 212 is located at the bottom of the accommodating cavity, and the cleaning tank 212 can accommodate the cleaning component 12 on the cleaning device 10. The cleaning tank 212 includes a cleaning tray 2123, and the cleaning liquid is accommodated in the cleaning tray 2123. The shape and number of the cleaning trays 2123 correspond to the shape and number of the rags 122 on the cleaning component 12. Preferably, in this embodiment, two cleaning trays 2123 are provided in the cleaning tank 212, and the two cleaning trays 2123 are symmetrically installed on the bottom wall of the cleaning tank 212. Please refer to Figure 1 The cleaning device 10 is provided with two rags 122 and a rag mounting bracket 121. After returning to the base station 21, the cleaning device 10 enters the receiving chamber and allows the rags 122 on the cleaning assembly 12 to enter the cleaning tray 2123. The rags 122 are cleaned by the rotational movement between the rags 122 and the cleaning tray 2123. It should be noted that the base station 21 may also include conventional components of existing base stations 21, such as an energy system, a negative pressure suction system, a sewage tank, and a clean water tank, which will not be detailed here.

[0071] In this utility model, please refer to Figure 12 The cleaning tank 212 is equipped with a heating device 22 for heating the cleaning liquid. In the prior art, a heating module is typically installed in the water path of the base station 21 for heating. However, scale easily accumulates inside the heating module during prolonged use, making it difficult to maintain. In contrast, the heating device 22 in this solution directly heats the cleaning liquid within the cleaning tank 212 of the base station 21. This arrangement prevents scale from forming within the cleaning tank 212. Even if scale does form, the cleaning tank 212 is easily maintained, for example, by disassembling the cleaning tank 212 for cleaning.

[0072] Specifically, the heating device 22 can be set at any position of the cleaning tank 212, such as the bottom wall, side wall, etc. of the cleaning tank 212, as long as it can heat the cleaning liquid. The specific structure of the heating device 22 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 22 for heating the cleaning liquid is not limited. For example, it can directly heat the cleaning liquid located in the cleaning disk 2123, or it can first heat the cleaning liquid entering the cleaning disk 2123, so that the heated cleaning liquid is directly passed into the cleaning disk 2123. Since the heating device 22 is provided in the cleaning tank 212, the distance between the heating device 22 and the cleaning tank 212 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.

[0073] When the cleaning device 10 completes a cleaning operation and returns to the base station 21, the cleaning component 12 is placed in the cleaning tank 212, and the rag 122 contacts the cleaning liquid in the cleaning tray 2123. If the rag 122 needs to be cleaned with hot water, the heating device 22 is operated to heat the cleaning liquid, and the rag 122 is cleaned in the heated cleaning liquid. At this time, the heat storage device 13 on the cleaning device 10 absorbs the heat in the cleaning liquid through the rag 122 and stores the heat. Alternatively, during the cleaning process, the heat storage device 13 directly contacts the cleaning liquid, so that it can directly absorb heat from the cleaning liquid. When the rag 122 completes the cleaning action, the cleaning device 10 leaves the base station 21 and performs a cleaning operation on the ground. At this time, the heat storage device 13 releases heat and conducts the heat to the rag 122, so that the rag 122 obtains heat replenishment, thereby extending the time for the rag 122 to mop the floor with hot water and improve the cleaning effect of the rag 122.

[0074] In order to facilitate the control of the heating temperature of the cleaning liquid in the cleaning disk 2123, preferably, refer to Figure 12 and Figure 14 In an example of the cleaning system 20 of the present invention, the heating device 22 further includes a temperature sensor 221, which is arranged in the cleaning tank 212 to detect the temperature of the cleaning liquid in the cleaning tank 212. The temperature sensor 221 can be arranged at any position such as the bottom wall or side wall of the cleaning tank 212 that can detect the temperature of the cleaning liquid in the cleaning tank 212. The number of temperature sensors 221 set can be one or more. Preferably, in this embodiment, the temperature sensor 221 is arranged on the bottom wall of the cleaning tank 212. With this arrangement, the detection accuracy of the temperature sensor 221 is less affected by the liquid level of the cleaning liquid. By setting the temperature sensor 221, the heating temperature of the cleaning liquid can be monitored in real time, so that the heating temperature of the cleaning liquid can be controlled more accurately.

[0075] In an example of the cleaning system 20 of the present invention, see Figure 12 and Figure 14The heating device 22 is provided on the bottom wall of the cleaning tank 212 to heat the cleaning liquid and store energy in the heat storage device 13 when the rag 122 is cleaning. Since the bottom wall of the cleaning tank 212 is provided with a cleaning tray 2123, the heating device 22 is provided on the bottom wall of the cleaning tank 212, that is, the heating device 22 is provided on the bottom wall of the cleaning tank 212. One heating device 22 can be provided, that is, one heating device 22 heats the cleaning liquid in multiple cleaning trays 2123 on the cleaning tank 212 at the same time; multiple heating devices 22 can also be provided, and the multiple heating devices 22 correspond to the multiple cleaning trays 2123 respectively, that is, each heating device 22 corresponds to one cleaning tray 2123. Preferably, in this embodiment, two cleaning trays 2123 are provided, and two heating devices 22 are provided, each heating device 22 corresponds to one cleaning tray 2123, that is, one heating device 22 is provided on the bottom wall of each cleaning tray 2123. The heating area of the heating device 22 can cover the entire bottom wall of the cleaning tray 2123, or it can cover only a portion of the bottom wall of the cleaning tray 2123, depending on the installation and heating requirements. In this embodiment, the heating device 22 is partially installed on the bottom wall of the cleaning tray 2123. By installing the heating device 22 on the bottom wall of the cleaning tank 212, the cleaning liquid in the cleaning tank 212 can be heated more evenly.

[0076] See also Figure 12 、 Figure 15 and Figure 16 The cleaning liquid inlet pipe 224 is in thermal contact with the heating device 22 to preheat the cleaning liquid before it enters the cleaning tank 212. Specifically, the upper portion of the heating device 22 is in thermal contact with the cleaning liquid in the cleaning tank 212. This means that the heat generated by the heating device 22 can be directly transferred to the cleaning liquid in the cleaning pan 2123, thereby heating the cleaning liquid. The cleaning pan 2123 is provided with an inlet pipe 224 at the bottom, through which the cleaning liquid enters the cleaning pan 2123. The lower portion of the heating device 22 is in thermal contact with the inlet pipe 224 of the cleaning tank 212. This means that the heat generated by the heating device 22 can be directly transferred to the inlet pipe 224, and then to the cleaning liquid within the inlet pipe 224. With this arrangement, as the cleaning liquid flows through the inlet pipe 224, the heating device 22 can heat the cleaning liquid in the inlet pipe 224, thereby preheating the cleaning liquid before it enters the cleaning tank 212. When the cleaning liquid enters the cleaning tray 2123 from the water inlet pipe 224, the heating device 22 can reheat the cleaning liquid in the cleaning tray 2123, thereby fully utilizing the heat generated by the heating device 22, improving the heating efficiency of the cleaning liquid, and reducing the waiting time for heating the cleaning liquid.

[0077] In order to improve the cleaning effect of the rag 122 in the cleaning liquid, preferably, in an example of the cleaning system 20 of the present invention, the cleaning plate 2123 includes a bottom wall and cleaning ribs 2121, and the cleaning ribs 2121 are arranged on the bottom wall. The cleaning ribs 2121 are smoothly connected to the bottom wall. When the cleaning device 10 returns to the base station 21 to clean the rag 122, the rag 122 cooperates with the cleaning tank 212 for cleaning. At this time, the rag 122 can contact the bottom wall and the cleaning ribs 2121 at the same time to achieve at least the first cleaning of the bottom wall by the rag 122, so that when cleaning the rag 122, the cleaning tank 212 can be cleaned at the same time by the rotation of the rag 122.

[0078] The cleaning rib 2121 can be a long strip convex structure, or a plurality of block convex structures distributed at intervals. The cleaning rib 2121 can be provided with one or more. Figure 12 Each cleaning tray 2123 has a cleaning rib 2121 on its bottom wall. The cleaning rib 2121 is a long, raised structure extending from the center of the cleaning tray 2123 toward the outer periphery 141. The cleaning rib 2121 increases the contact area and contact strength between the cleaning liquid and the rag 122, thereby improving the cleaning effect of the rag 122.

[0079] In this example, see Figure 12 The heating surface of the heating device 22 at least covers the cleaning ribs 2121. The heating surface of the heating device 22 may completely cover the surface of the cleaning ribs 2121, or it may only partially cover the surface of the cleaning ribs 2121. Preferably, in this embodiment, the heating surface of the heating device 22 covers the entire surface of the cleaning ribs 2121. That is, when the heating device 22 heats, the surface temperature of the cleaning ribs 2121 also rises, heating the cleaning liquid in contact with the surfaces of the cleaning ribs 2121. This arrangement can improve the heat transfer efficiency between the rag 122 and the cleaning ribs 2121, and further improve the heat transfer efficiency between the rag 122 and the heat storage device 13, thereby improving the heat storage effect of the heat storage device 13. In another embodiment, the heating surface of the heating device 22 may only cover a portion of the bottom wall of the cleaning tank 212, as long as the heating requirements of the cleaning liquid are met. In other embodiments, the heating surface of the heating device 22 may also cover a portion of the bottom wall and the surface of the cleaning ribs 2121.

[0080] In an example of the cleaning system 20 of the present invention, see Figure 12 、 Figure 15 and Figure 16The heating device 22 includes a heat-conducting plate 222 and a heating element 223. The heating element 223 is located on the side of the heat-conducting plate 222 facing away from the bottom wall of the cleaning plate 2123. The heat generated by the heating element 223 is transferred to the cleaning liquid within the cleaning plate 2123 through the heat-conducting plate 222. The heat-conducting plate 222 can be made of metal, such as aluminum, copper, or other materials with good thermal conductivity, such as ceramic and graphite. The heating element 223 can be a heating wire, a heating plate, a heating tube, or other structures. Preferably, in this embodiment, the heating element 223 is a heat-conducting tube structure. This arrangement allows the heating element 223 to achieve a relatively uniform heating effect in the circumferential direction. The heat-conducting plate 222 and the bottom wall of the cleaning tank 212 are integrally formed. It should be noted that the term "integrated" here refers to the fact that after the heat-conducting plate 222 is installed in the cleaning tank 212, the original structure and shape of the cleaning tank 212 is not affected. This includes but is not limited to the arrangement in which the heat-conducting plate 222 and the bottom wall of the cleaning tank 212 are integrally formed and connected. The heat conducting plate 222 can be integrally formed with the bottom wall of the washing tank 212 by injection molding, or can be integrally connected to the bottom wall of the washing tank 212 by snap-fitting. This arrangement can reduce the gap between the heat conducting plate 222 and the bottom wall of the washing tank 2123, which not only facilitates sealing of the bottom wall of the washing tank 2123 but also improves the aesthetics of the bottom wall of the washing tank 2123.

[0081] In an example of the cleaning system 20 of the present invention, see Figure 12 and Figure 13 The bottom wall of the cleaning tank 212 includes a concave cavity 23 that is recessed toward the ground, and the concave cavity 23 is connected to the drain outlet 231 of the cleaning tank 212. The concave cavity 23 can be located at any position on the bottom wall of the cleaning tray 2123, and the shape of the concave portion can be rectangular, fan-shaped, polygonal, etc. The two cleaning trays 2123 can share one concave cavity 23, or each can be provided with a different concave cavity 23. Preferably, in this embodiment, the concave cavity 23 is provided between the two cleaning trays 2123, and the concave cavity 23 is connected to the two cleaning trays 2123 at the same time. A wiper portion 2122 is provided at the opening position of the concave cavity 23, and the wiper portion 2122 is located at the connection position between the concave cavity 23 and the bottom wall of the cleaning tank 212.

[0082] See also Figure 13The wiper portion 2122 protrudes from the bottom wall of the cleaning tank 212 to prevent some water from the rag 122 from entering the cavity 23 when the rag 122 rotates relative to the cleaning tank 212. The wiper portion 2122 can be any structure, such as an inclined block structure, a prismatic structure, or an elongated block structure, that can prevent some water from entering the cavity 23 when the rag 122 rotates relative to the cleaning disk 2123. Preferably, in this embodiment, the wiper portion 2122 is a sloped structure disposed at the opening of the cavity 23. This configuration creates a relatively gentle frictional force when the rag 122 contacts the wiper portion 2122, reducing the probability of the rag 122 becoming stuck during rotation. In this embodiment, by providing a cavity 23 and a wiper portion 2122, when the rag 122 rotates relative to the cleaning disc 2123, the wiper portion 2122 can scrape the dirty water on the rag 122 into the cavity 23, thereby reducing the probability of the water in the cleaning tank 212 being secondary contaminated during the cleaning process of the rag 122, thereby helping to improve the cleaning effect of the rag 122.

[0083] In an example of the cleaning system 20 of the present invention, when the cleaning device 10 performs the cleaning action of the rag 122 according to the predetermined cleaning times, the heating device 22 is configured to perform heating for a preset time, and the preset time is less than the total time of the cleaning action of the rag 122. The predetermined cleaning times of the cleaning device 10 are at least two times. In actual cleaning operations, the predetermined cleaning times are specifically determined by the dirtiness of the cleaning floor. The total time of the cleaning action of the rag 122 refers to the sum of the cleaning times of multiple cleaning actions performed in the cleaning tank 212 during the process of the rag 122 completing the predetermined cleaning times. This arrangement can avoid the heating device 22 from heating after the cleaning action of the rag 122 is completed, thereby reducing energy waste and achieving energy-saving effects.

[0084] In an example of the cleaning system 20 of the present invention, when the cleaning device 10 performs a cleaning operation with the rag 122 according to a predetermined number of cleaning operations, the heating device 22 is configured to stop heating before the cleaning device 10 performs the last cleaning operation with the rag 122. This configuration allows the heating device 22 to be turned off in advance before the cleaning operation is completed, which helps to cool the heating device 22 and the base 211 in advance, and reduces the probability of burns when the cleaning device 10 is transported to the base 21 after the cleaning operation is completed.

[0085] In an example of the cleaning system 20 of the present invention, a heat insulating member 24 is provided on the side of the bottom wall of the cleaning tank 212 facing the ground, and the projection of the heat insulating member 24 covers the projection of the heating device 22 along the height direction of the base 211. A cover plate 25 is installed on the side of the cleaning tank 212 facing the ground. The heat insulating member 24 can be a cover plate 25, which is made of a heat insulating material. The cover plate 25 reduces the heat transferred from the heating device 22 to the ground. The heat insulating member 24 can also be a separate heat insulating part located between the cover plate 25 and the heating device 22, and the heat insulating part and the cover plate 25 together block the heat transferred from the heating device 22 to the ground. Preferably, in this embodiment, please refer to Figure 17 The thermal insulation member 24 is a separate component positioned between the cover plate 25 and the heating device 22. The specific shape and structure of the thermal insulation member 24 are not limited, as long as the projection of the thermal insulation member 24 covers the projection of the heating device 22. Preferably, in this embodiment, the shape of the thermal insulation member 24 corresponds to the shape of the cover plate 25, and the thermal insulation member 24 is fixedly mounted to the cover plate 25. This arrangement facilitates the installation of the thermal insulation member 24 outside the cover plate 25 and also provides a larger insulation area at the bottom wall of the cleaning tank 212, thereby improving the thermal insulation effect.

[0086] The present invention further provides a cleaning assembly 12, comprising a rag mounting frame 121 and a rag 122, wherein the rag 122 is connected to the rag mounting frame 121; at least one of the rag mounting frame 121 and the rag 122 is connected to a heat storage device 13, which is configured to absorb heat when the rag 122 is cleaned by a cleaning solution and release heat to the rag 122 when the rag 122 performs a cleaning operation. In the cleaning assembly 12 of this embodiment, the configuration and beneficial effects of the rag mounting frame 121, the rag 122, and the heat storage device 13 can be referred to the relevant descriptions in the above embodiments and will not be repeated here.

[0087] In summary, the present invention provides a cleaning device 10, a cleaning system 20, and a cleaning assembly 12. The cleaning device 10 is provided with a heat storage device 13 on the cleaning assembly 12, and the heat storage device 13 is thermally connected to the rag 122 so that when the rag 122 is cleaning, the heat storage device 13 absorbs the heat of the cleaning liquid and releases the heat to the rag 122 when the rag 122 is cleaning. In this way, when the rag 122 is cleaning, the heat storage device 13 can transfer heat to the rag 122. During the cleaning process, the rag 122 can be heated by the heat storage device 13 to achieve hot mopping of the rag 122, which is conducive to removing stubborn stains, oil stains, etc. on the ground. Therefore, compared with mopping with normal temperature water, the cleaning effect of the ground can be improved. At the same time, since the heat storage device 13 only needs to absorb the heat of the cleaning liquid when the rag 122 is cleaning, and there is no need to set an additional heat source for the cleaning assembly 12, the structure is simple and easy to implement. At the same time, since the cleaning tank 212 is provided with a heating device 22, the cleaning assembly 12 is placed in the cleaning tank 212, and the rag 122 is in contact with the cleaning liquid in the cleaning tray 2123. If the rag 122 needs to be cleaned with hot water, the heating device is operated to heat the cleaning liquid, and the rag 122 is cleaned in the heated cleaning liquid. At this time, the heat storage device 13 on the cleaning device 10 absorbs the heat from the cleaning liquid through the rag 122 and stores the heat. When the rag 122 completes the cleaning action, the cleaning device 10 detaches from the base station 21 and performs the cleaning operation on the ground. At this time, the heat storage device 13 releases heat and conducts the heat to the rag 122, so that the rag 122 obtains heat replenishment, thereby extending the time for the rag 122 to mop the floor with hot water and improving the cleaning effect of the rag 122.

[0088] 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.
