[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0045] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0046] The utility model proposes a hot water module, which is mainly used in cleaning equipment (for example, base stations, sweepers, sweeping and mopping machines, floor scrubbers, etc.) to provide hot water for the cleaning equipment. Of course, the hot water module of the utility model can also be used in other types of equipment to heat water.

[0047] Combined with reference Figures 1 to 3In this embodiment, the hot water module includes a shell 10 and a heating pipe 20. The shell 10 is provided with a through hole 11, and the shell 10 is configured with an inner cavity. The heating pipe 20 is installed in the inner cavity of the shell 10, and the heating pipe 20 has a water inlet 21 and a water outlet 22. Exemplarily, the water inlet 21 and the water outlet 22 are respectively located at the two ends of the heating pipe 20. When the hot water module is used on a cleaning device, the water inlet pipeline of the cleaning device is connected to the water inlet 21 of the heating pipe 20, and the water outlet pipeline of the cleaning device is connected to the water outlet 22 of the heating pipe 20; the through hole 11 provided on the shell 10 facilitates the connection between the water inlet pipeline and the water inlet 21, and / or the water outlet pipeline is connected to the water outlet 22. Exemplarily, at least two through holes 11 are provided on the shell 10, and the water inlet pipeline and the water outlet pipeline can pass through different through holes 11 respectively, and can also pass through the same through hole 11. The water inlet pipe can be directly connected to the water inlet 21 or indirectly connected through other structures; the water outlet pipe can be directly connected to the water outlet 22 or indirectly connected through other structures. When the hot water module is working, the cleaning device delivers cold water to the water inlet 21 of the heating pipe 20 through the water inlet pipe. The cold water entering through the water inlet 21 is heated by the heating pipe 20 and flows to the water outlet 22. The heated hot water flows out from the water outlet 22 to the water outlet pipe and is delivered to the hot water demand location (for example, the cleaning tank of the base station to achieve hot water mop washing).

[0048] The technical solution of the hot water module of the present embodiment is to add a shell 10 and install the heating tube 20 in the inner cavity of the shell 10, so that the heating tube 20 is separated from the surrounding components, so that in the cleaning equipment using the hot water module of the present embodiment, the heating tube 20 will be isolated from the water pipe and other surrounding electrical components through the shell 10, thereby playing a heat insulation role. At the same time, when the water pipe leaks or other emergencies cause splashing water, the splashing water will be blocked by the shell 10, thereby preventing water from splashing onto the surface of the heating tube 20 and generating steam, thereby avoiding the occurrence of short circuits in other surrounding electrical components caused by steam, thereby ensuring the safety of the cleaning equipment.

[0049] In some embodiments, the heating tube 20 is spaced apart from the internal structure of the shell 10, that is, no part of the heating tube 20 is directly in contact with the internal structure of the shell 10. The heating tube 20 can be indirectly connected to the internal structure of the shell 10 through an intermediate component, and can also be suspended in the inner cavity of the shell 10 through an intermediate component. In this way, the heating tube 20 is prevented from melting and deforming the internal structure of the shell 10 due to excessively high temperature when dry-burning.

[0050] See also Figure 3 and Figure 4In some embodiments, a heat insulating member 30 is installed near both ends of the heating tube 20, and the heat insulating member 30 is connected to the housing 10. That is, in this embodiment, the heating tube 20 is connected to the housing 10 through the heat insulating member 30 at both ends, so that the heating tube 20 and the housing 10 are assembled. The heat insulating member 30 is arranged near both ends of the heating tube 20, so that it can be kept away from the heating part of the heating tube 20 as much as possible.

[0051] In other embodiments, the heating tube 20 is suspended in the inner cavity of the shell 10, for example, the heating tube 20 is suspended in the inner cavity by binding ropes or the like. Of course, in other embodiments, the heating tube 20 can also be connected to the structure inside the shell 10 through other parts via the heat insulating member 30. Among them, the heat insulating member 30 can be a structural member made of heat insulating materials such as silicone material and ceramic material. In some embodiments, the heat insulating member 30 can be a silicone ring, a ceramic ring, etc., which is sleeved on the end of the heating tube 20.

[0052] See also Figure 2 , Figure 3 and Figure 5 In some embodiments, the inner wall of the housing 10 closest to the heating tube 20 is provided with a recessed area 12 (i.e., a part of the inner cavity) facing the heating tube 20. In this embodiment, by providing the recessed area 12 on the inner wall of the housing 10, the distance from the inner wall of the housing 10 closest to the heating tube 20 to the heating tube 20 is increased, thereby reducing the influence of the inner wall of the housing 10 closest to the heating tube 20 on the high temperature of the heating tube 20, thereby improving the safety of the housing 10.

[0053] In other embodiments, the inner wall of the shell 10 that is less than a preset distance from the heating tube 20 is provided with a recessed area 12 facing the heating tube 20. When the inner wall of the shell 10 is too close to the heating tube 20 (such as less than a preset distance), when the heating tube 20 is heated or dry-burned, the inner wall of the shell 10 is likely to be melted and deformed by the heat radiated by the high-temperature heating tube 20, which poses a great safety hazard. Therefore, the present embodiment increases the distance from the inner wall of the shell 10 to the heating tube 20 by providing the recessed area 12 facing the heating tube 20 on the inner wall of the shell 10 that is less than a preset distance from the heating tube 20, thereby avoiding the inner wall of the shell 10 from being melted and deformed by the heat radiated by the high-temperature heating tube 20 and eliminating the safety hazard.

[0054] In some embodiments, the inner wall of the housing 10 closest to the heating tube 20 is provided with a heat insulation layer (not shown in the figure) facing the heating tube 20; and / or, the inner wall of the housing 10 that is less than a preset distance from the heating tube 20 is provided with a heat insulation layer (not shown in the figure) facing the heating tube 20. In this embodiment, by adding a heat insulation layer on the inner wall of the housing 10 closest to the heating tube 20 or the inner wall of the housing 10 that is less than a preset distance from the heating tube 20, the heat insulation layer blocks most of the heat radiated from the heating tube 20 to the inner wall of the housing 10, thereby reducing the heat radiated from the heating tube 20 to the inner wall of the housing 10, thereby avoiding the situation where the inner wall of the housing 10 is melted and deformed by the heat radiated by the high-temperature heating tube 20. Among them, the heat insulation layer can be a heat insulation material layer (such as a ceramic layer) coated on the inner wall of the housing 10, or it can be a heat insulation pad (such as a soft rubber pad) arranged (such as pasted) on the inner wall of the housing 10. This embodiment can be combined with the above-mentioned scheme of setting a recessed area 12 on the inner wall of the housing 10, so as to better ensure the safety of the housing 10.

[0055] See also Figure 7 In some embodiments, the housing 10 is provided with a water leakage hole 13 connected to its inner cavity. By providing the water leakage hole 13, when an emergency occurs and water enters the housing 10, the water in the housing 10 will flow out of the housing 10 through the water leakage hole 13, thereby preventing water from remaining and accumulating inside the housing 10, and ensuring the safety of the heating pipe 20 and other components inside the housing 10. The water leakage hole 13 can be set at the lowest terrain position of the housing 10, ensuring that the water accidentally entering the housing 10 will flow to the water leakage hole 13 faster under the action of gravity, and then flow out of the housing 10 faster.

[0056] See also Figure 2 , Figure 3 and Figure 5In some embodiments, the shell 10 includes an upper shell 101 and a lower shell 102 that are spliced ​​and fixed. The upper shell 101 and the lower shell 102 can be fixed by screws, buckles or other methods; the upper shell 101 and / or the lower shell 102 are provided with a card slot 17 corresponding to the thermal insulation member 30 one by one, and the card slot 17 is provided with an entrance for the thermal insulation member 30 to be inserted, and the two thermal insulation members 30 are respectively engaged in the corresponding card slots 17. When the slot 17 is set on the lower shell 102, the entrance of the slot 17 faces one side of the upper shell 101; when the slot 17 is set on the upper shell 101, the entrance of the slot 17 faces one side of the lower shell 102; when the slot 17 is set on both the upper shell 101 and the lower shell 102, the entrances of the slot 17 face one side of the lower shell 102 and the upper shell 101 respectively. When the upper shell 101 and the lower shell 102 are spliced ​​and fixed, the entrances of the two slots 17 thereon can be butted to achieve connection, or can be not butted and spaced relative. In this embodiment, the heating tube 20 is respectively inserted into the corresponding slot 17 from the entrance of the corresponding slot 17 through the heat insulation 30 at both ends, so that the heating tube 20 and the lower shell 102 are assembled. Among them, the heat insulation 30 can be an interference fit with the slot 17 to clamp the end of the heating tube 20 in the slot 17.

[0057] See also Figure 2 and Figure 3 In some embodiments, the housing 10 is provided with a connection terminal 23 which is respectively fixed and electrically connected to the two ends of the heating tube 20, and the connection terminal 23 is covered with a rubber sleeve 24 which abuts against the upper housing 101. In this embodiment, the two ends of the heating tube 20 are respectively connected to the live wire and the neutral wire by setting the connection terminal 23, and the connection terminal 23 is covered with a rubber sleeve 24 to insulate the connection terminal 23 to prevent leakage at the connection terminal 23 and ensure safety in use; and the rubber sleeve 24 on the connection terminal 23 abuts against the upper housing 101, and the upper housing 101 abuts against the rubber sleeve 24 to prevent the two ends of the heating tube 20 from moving toward the upper housing 101 and to prevent the heating tube 20 from rotating, that is, the two ends of the heating tube 20 are stably restricted in the card slot 17, ensuring the stability and reliability of the assembly of the heating tube 20 and the housing 10. Of course, in other embodiments, the heating tube 20 can also be fixed to the housing 10 in other ways.

[0058] See also Figure 1In some embodiments, the hot water module further includes a water outlet connector 40, which includes a first connector 41, a second connector 42, and a third connector 43 that are interconnected, that is, the water outlet connector 40 is a three-way structural member, the first connector 41 is connected to the water outlet 22, the second connector 42 is installed with a temperature sensor 50, and the third connector 43 is used to connect the water outlet pipeline. This embodiment only has a simple structure of a three-way water outlet connector 40, which not only realizes the connection between the water outlet pipeline and the water outlet 22 of the heating pipe 20, but also realizes the installation of the temperature sensor 50, and the temperature sensor 50 is directly in contact with the hot water flowing out of the water outlet 22, which ensures the accuracy of the temperature detected by the temperature sensor 50.

[0059] See also Figure 1 and Figure 2 In some embodiments, the hot water module further includes a soft rubber tube section 60, and a sealed butt-jointed water outlet joint 25 is provided on the water outlet 22. The water outlet joint 25 is plugged into one end of the soft rubber tube section 60 by interference, and the first joint 41 is plugged into the other end of the soft rubber tube section 60 by interference. In this embodiment, by adding a soft rubber tube section 60 and butt-jointing the water outlet joint 25 on the water outlet 22, the two ends of the soft rubber tube section 60 are respectively sleeved on the first joint 41 and the water outlet joint 25 by interference, so as to achieve the sealed communication between the first joint 41 and the water outlet 22 in a simple manner.

[0060] In some embodiments, clamps 61 are respectively provided at both ends of the soft rubber tube section 60, and the clamps 61 clamp the outer peripheral wall of the soft rubber tube section 60. This embodiment further clamps the outer peripheral walls of both ends of the soft rubber tube section 60 by the clamps 61, thereby better ensuring the sealing of the connection between the soft rubber tube section 60 and the first joint 41 and the water outlet joint 25, and avoiding water leakage at both ends of the soft rubber tube section 60. The clamps 61 can be structural parts such as clamping tube torsion springs, cable ties, etc. that can clamp the outer peripheral wall.

[0061] In some embodiments, the water outlet connector 40 is fixed to the outer wall of the housing 10. For example, the water outlet connector 40 may be screwed to the outer wall of the housing 10, or may be fastened to the housing 10 by a snap-fit ​​structure, or may be bonded to the housing 10. In this embodiment, by fixing the water outlet connector 40 to the outer wall of the housing 10, the first joint 41 of the water outlet connector 40 and the heating pipe 20 are relatively fixed, that is, the relative position of the first joint 41 and the water outlet 22 is fixed, thereby making the connection between the two ends of the soft rubber tube section 60 more reliable and stable.

[0062] See also Figure 1 and Figure 2In some embodiments, a sealed butt-jointed water inlet connector 26 is provided on the water inlet 21, two through holes 11 are provided on the housing 10, the water inlet connector 26 is passed through one of the through holes 11, and the water outlet connector 25 is passed through the other through hole 11. In this embodiment, two through holes 11 are provided on the housing 10, and the water inlet connector 26 is butt-jointedly provided on the water inlet 21, so that the water inlet connector 26 and the water outlet connector 25 are respectively passed through the two through holes 11, so that the water inlet pipeline of the cleaning equipment can be more conveniently connected to the water inlet connector 26 to achieve communication with the water inlet 21, and the soft rubber tube section 60 can also be more conveniently connected to the water outlet connector 25.

[0063] In some embodiments, the sealing connection between the water outlet joint 25 and the water outlet 22, and the sealing connection between the water inlet joint 26 and the water inlet 21 may be screw connection, welding or bonding, or other connection methods.

[0064] See also Figure 2 and Figure 4 In some embodiments, the hot water module also includes an automatic thermostat 71 and a manual thermostat 72 installed on the outer wall of the heating tube 20, and the automatic thermostat 71 and the manual thermostat 72 are electrically connected to the heating tube 20. Exemplarily, the automatic thermostat 71, the heating tube 20 and the manual thermostat 72 are connected in series in a power supply circuit, and the automatic thermostat 71 and the manual thermostat 72 detect the temperature of the outer wall of the heating tube 20.

[0065] During the operation of the hot water module, when the automatic thermostat 71 detects that the temperature of the outer wall of the heating tube 20 reaches the first set temperature, the automatic thermostat 71 will trip to cut off the power supply circuit of the heating tube 20, so that the heating tube 20 stops working. When the automatic thermostat 71 detects that the temperature of the outer wall of the heating tube 20 returns to below the first set temperature, the automatic thermostat 71 will automatically recover to restore the power supply circuit of the heating tube 20 and resume the operation of the heating tube 20. Therefore, the automatic adjustment and control of the temperature of the heating tube 20 is achieved through the automatic thermostat 71. When the manual thermostat 72 detects that the temperature of the outer wall of the heating tube 20 reaches the second set temperature (the second set temperature is higher than the first set temperature), the automatic thermostat 71 does not trip (it may fail due to a malfunction or damage), which means that the temperature of the outer wall of the heating tube 20 is too high. It is determined that the heating tube 20 has dry-burned or other abnormal conditions. The user can actively turn off the manual thermostat 72 to cut off the power supply circuit of the heating tube 20 to stop the heating tube 20 from working. Moreover, when the temperature of the outer wall of the heating tube 20 returns to below the second set temperature, the manual thermostat 72 will not automatically recover to prevent the heating tube 20 from continuing to dry-burn. The manual thermostat 72 needs to be manually recovered by the user. By setting the manual thermostat 72, the situation where the heating tube 20 continues to dry-burn due to the failure of the automatic thermostat 71 or other abnormal conditions is avoided, thereby protecting the safety of the operation of the heating tube 20.

[0066] See also Figure 4In some embodiments, the hot water module also includes a fixing component 80 wrapped around the heating tube 20, the fixing component 80 includes a fixing part 81 and a heat conducting part 82, the automatic thermostat 71 and the manual thermostat 72 are arranged corresponding to the heat conducting part 82 and fixed on the fixing component 80, the automatic thermostat 71 and the manual thermostat 72 can be fixed to one of the fixing part 81 and the heat conducting part 82, or both the fixing part 81 and the heat conducting part 82 can be fixed; a thermal pad 90 is provided between the automatic thermostat 71 and the manual thermostat 72 and the heat conducting part 82, one side of the thermal pad 90 is in contact with the heat conducting part 82, and the other side of the thermal pad 90 is in contact with the automatic thermostat 71 and the manual thermostat 72. In this embodiment, a fixing component 80 wrapped around the heating tube 20 is added to fix the automatic temperature controller 71 and the manual temperature controller 72 on the fixing component 80, and the automatic temperature controller 71 and the manual temperature controller 72 are fixed on the fixing component 80 corresponding to the heat conducting portion 82. Since the fixing component 80 is wrapped around the heating tube 20, more heat from the outer wall of the heating tube 20 can be transferred to the automatic temperature controller 71 and the manual temperature controller 72, so that the temperature detected by the automatic temperature controller 71 and the manual temperature controller 72 is more accurate; in addition, a thermal pad 90 is provided between the heat conducting portion 82 of the fixing component 80 and the automatic temperature controller 71 and the manual temperature controller 72, so that the automatic temperature controller 71 and the manual temperature controller 72 can better fit with the heat conducting portion 82, further improving the heat transferred from the outer wall of the heating tube 20 to the automatic temperature controller 71 and the manual temperature controller 72, and further improving the temperature detection accuracy of the automatic temperature controller 71 and the manual temperature controller 72.

[0067] In some embodiments, the thermal pad 90 may be a graphite thermal interface material, which can withstand very high temperatures and has a certain amount of compression, so as to better achieve the fit between the automatic thermostat 71 and the manual thermostat 72 and the thermal conductive portion 82. Of course, in other embodiments, the thermal pad 90 may also be other compressible thermal conductive materials, such as thermal grease, thermal adhesive pads, etc.

[0068] See also Figure 3 and Figure 5 In some embodiments, a wiring groove 14 extending along the length direction of the heating tube 20 is constructed in the shell 10, so that the wire harness inside the shell 10 can be arranged along the wiring groove 14, and the wire harness is confined in the wiring groove 14 to prevent the wires from being scattered, thereby avoiding the wires from contacting the heating tube 20 and melting, thereby ensuring the safety of the line. A wire hole 15 is provided on one side of the shell 10 close to the wiring groove 14, which makes it easier for the wires in the wiring groove 14 to pass through the shell 10.

[0069] In some embodiments, a clamping pipe structure 16 is provided on the outer wall of the shell 10 near the water inlet 21, and a section of the water inlet pipe near the water inlet 21 is fixed and clamped by the clamping pipe structure 16 to prevent the section of the water inlet pipe near the water inlet 21 from shaking, thereby ensuring the connection stability between the water inlet pipe and the water inlet 21.

[0070] See also Figure 1 , Figure 3 and Figure 6 In some embodiments, the outer wall of the housing 10 is provided with a plurality of clamping pipe structures 16 disposed near the water inlet 21, and each clamping pipe structure 16 is located at a different position of the water inlet 21. In this embodiment, by disposing a plurality of clamping pipe structures 16 located at different positions of the water inlet 21, a suitable clamping pipe structure 16 can be selected for the water inlet pipeline, and the arrangement of the water inlet pipeline is more flexible and can be applied to cleaning equipment of different models. Of course, other pipelines in the cleaning device can also be fixed or stored by the clamping pipe structure 16 (for example, the cleaning liquid pipeline, the water outlet pipeline, etc.).

[0071] In some embodiments, the hot water module further includes a main control board (not shown in the figure), which is electrically connected to the electrical components of the hot water module, wherein the electrical components of the hot water module may include a heating tube 20, a temperature sensor 50, an automatic thermostat 71, and a manual thermostat 72, etc. The main control board controls the operation of each electrical component and the data or information transmission between each electrical component.

[0072] It should be noted that the above-mentioned various embodiments of the hot water module of the utility model can be arbitrarily combined or combined to form a new embodiment when there is no contradiction or conflict between them.

[0073] See also Figure 8 The utility model also proposes a cleaning device, including a device body 100, a water inlet pipe 200, a water outlet pipe 300 and the above-mentioned hot water module 400, the shell 10 is installed on the device body 100, the water inlet pipe 200 is connected to the water inlet, and the water outlet pipe 300 is connected to the water outlet; the specific structure of the hot water module 400 refers to the above-mentioned embodiment. Since the cleaning device adopts all the technical solutions of all the embodiments of the above-mentioned hot water module 400, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0074] In some embodiments, the cleaning device further comprises an adapter 500 mounted on the device body 100, wherein a main control board is integrated in the adapter 500, and the main control board is electrically connected to the electrical components of the hot water module 400 to control the operation of the hot water module 400. In this embodiment, the main control board for controlling the operation of the hot water module 400 is integrated into the adapter 500, and the excellent waterproof performance of the adapter 500 itself is utilized to achieve the sealing requirement of the main control board, thereby avoiding the need for additional structures to seal the main control board, reducing costs and saving space.

[0075] In some embodiments, the cleaning device further includes a filter assembly 600, which is installed between the hot water module and the hot water outlet (not shown in the figure). The hot water outlet refers to the outlet where the hot water is supplied to the hot water demand (for example, the water spray port of the cleaning tank facing the base station). It can be understood that the hot water module is prone to scale after a certain period of use, which gathers on the inner wall of the heating tube 20, and the hot water flowing out may also carry certain scale impurities, thereby affecting the water quality of the hot water; in addition, as the use time becomes longer and longer, the scale on the inner wall of the heating tube 20 becomes thicker and thicker, and during this period, larger pieces of scale may be peeled off and fall off, and flow out with the hot water. If the caliber of the hot water outlet is not large enough, it will cause the hot water outlet to be blocked, thereby affecting the supply of hot water and its water quality. In this embodiment, by setting the filter assembly 600 between the hot water module and the hot water outlet, impurities in the hot water can be filtered out to prevent the hot water outlet from being blocked, and the water quality of the hot water supply can be purified at the same time.

[0076] The filter assembly 600 can be set at any position on the path between the hot water module and the hot water outlet. For example, it can be set outside the water outlet 22 of the hot water module (such as: on the water outlet joint 25, on the soft rubber tube section 60, etc.); for another example, it can be set on the water outlet pipeline; for another example, it can be set before the hot water outlet (such as: the inside of the water outlet of the base station, etc.). The filter assembly 600 may include but is not limited to a filter net, a filter box, a filter paper, a reverse osmosis membrane, a magnetized water processor, an activated carbon adsorption processor, etc. The filter assembly 600 can be mesh-shaped, box-shaped, paper-shaped, membrane-shaped, bag-shaped, etc. The present application does not make specific restrictions on the installation position, structure, shape, material, etc. of the filter assembly 600, and it can be set or adjusted according to actual needs.

[0077] In some specific embodiments, see Fig. 9 and Fig.10, the filter assembly 600 includes an inlet 601, a filter unit 602, and an outlet 603. The hot water flowing out of the hot water module passes through the inlet 601, flows through the filter unit 602 for filtration, and then flows out from the outlet 603 to be supplied to the place where the hot water is needed. The filter unit 602 includes an upper shell 6021, a filter element 6022, and a bottom shell 6023. The upper shell 6021 and the bottom shell 6023 can be assembled to form a cavity therein, and the filter element 6022 is disposed in the cavity, and the hot water is filtered by the filter element 6022. For example, the filter element 6022 is a filter screen.

[0078] The utility model also proposes a cleaning system, including a base station and at least one robot, wherein the base station and / or at least one robot is the above-mentioned cleaning device. The specific structure of the cleaning device refers to the above-mentioned embodiment. Since the present cleaning system adopts all the technical solutions of all the above-mentioned cleaning device embodiments, and the above-mentioned cleaning device also includes the above-mentioned hot water module 400, the present cleaning system at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0079] The hot water module provided in the base station can realize hot water self-cleaning (for example, hot water washing the cleaning tank of the base station), and can also realize hot water washing of the robot's mopping parts (for example, mops, rollers, etc.) and hot water mopping (for example, providing hot water to the robot to provide hot water when the robot mops the floor) when the robot enters the base station for maintenance.
