[0054] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0055] It should be noted that the terms used here are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0056] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0057] As described in the background art, if there is too much scale or impurities deposited in the water pipeline in the cleaning base station, it will cause the cleaning base station to malfunction. In the existing technology, the water pipeline in the cleaning base station is usually disassembled for cleaning, which is cumbersome and has a high maintenance cost. However, when the water containing impurities and scale enters the cleaning device 60 used in conjunction with the cleaning base station, the impurities and scale may also block the water pipeline in the cleaning device 60, resulting in the cleaning device 60 being unable to work properly. Moreover, since the cleaning device 60 is small in size and the internal components are arranged closely, it is difficult to maintain the water pipeline in the cleaning device 60. The cleaning device 60 can be, for example, a sweeping robot, a vacuum cleaner, and a floor sweeper.

[0058] To avoid the above problems, refer to Figures 1 to 8 As shown, according to an embodiment of the present application, a cleaning base station is provided, which includes a main body 10, an input channel 21, a heating device 30, and a filtering device 40.

[0059] Among them, the input channel 21 is provided in the main body 10, the heating device 30 is provided in the main body 10 for heating the water in the input channel 21, and the filtering device 40 is installed in the main body 10 for filtering the water flowing out of the heating device 30.

[0060] Specifically, the input channel 21 of this embodiment is used to supply water to the heating device 30. The water heated by the heating device 30 flows into the filtering device 40. When scale is generated in the heating device 30 or the water in the heating device 30 contains impurities, the impurities and scale are filtered at the filtering device 40 when passing through the filtering device 40, thereby preventing the scale and impurities from blocking the water path of the cleaning base station. At the same time, thanks to the setting of the filtering device 40, most of the impurities or scale in the water path of the cleaning base station are deposited at the filtering device 40. When maintaining the cleaning base station, regularly cleaning the filtering device 40 can avoid blockage of the water path pipes in the cleaning base station in most cases. In addition, the setting of the cleaning base station in this embodiment can ensure that the water input from the cleaning base station to the cleaning device 60 does not contain impurities and scale, thereby avoiding blockage of the water path pipes in the cleaning device 60.

[0061] Further, the filtering device 40 includes a support portion 41 and a filtering portion 42. The filtering device 40 is detachably connected to the main body 10. The filtering portion 42 is connected to the support portion 41 for filtering the water flowing out of the heating device 30.

[0062] In this embodiment, the support portion 41 is used to support the filtering portion 42 to prevent the filtering portion 42 from detaching from the main body 10 under the action of external force during filtering. The filtering device 40 is detachably connected to the main body 10 to facilitate regular maintenance of the filtering portion 42 and avoid blockage of the filtering portion 42 by scale and impurities, thereby preventing the filtering device 40 from malfunctioning. In this embodiment, the filtering portion 42 is used to filter the water flowing out of the heating device 30. When the heating device 30 heats the water and causes scale to appear in the water or the water in the heating device 30 contains impurities, the filtering portion 42 is used to filter the scale and impurities in the water.

[0063] In some embodiments, the heating device 30 is communicated with the water outlet end of the water tank 20. A delivery channel 301 is connected to the water outlet end of the heating device 30. A filtering chamber 31 is further provided on the delivery channel 301. The filtering chamber 31 has a first opening located outside the main body 10. The inner wall surface of the filtering chamber 31 is provided with a water inlet 311 and a water outlet 312. The filtering device 40 is detachably connected to the first opening, that is, the filtering device 40 is mounted on the main body 10 from the outer peripheral surface of the main body 10, and the filtering portion 42 is located in the filtering chamber 31 for filtering the water flowing into the water inlet 311.

[0064] Specifically, in order to improve the assembly efficiency of the support part 41, the filtering chamber 31 has a first opening located outside the main body 10. That is to say, the support part 41 can be directly installed into the filtering chamber 31 outside the main body 10, or the support part 41 can be disassembled from the filtering chamber 31 outside the main body 10, so as to facilitate the maintenance of the filtering device 40. On the other hand, after the support part 41 is installed in the filtering chamber 31, the filtering part 42 is also located in the filtering chamber 31, and the water flowing into the filtering chamber 31 from the water inlet 311 needs to be filtered by the filtering part 42 before flowing out from the water outlet 312. That is, the filtering chamber 31 of this embodiment also has a positioning effect, so that the filtering part 42 can normally filter the water flowing into the filtering chamber 31.

[0065] It is worth mentioning that the water tank 20 can be a sewage tank or a clean water tank. When the water tank is a sewage tank, the sewage in the sewage tank is heated and evaporated by the heating device 30 and then condensed and collected in the return tank of the cleaning base station. Subsequently, the sewage remaining in the sewage tank flows out through the water outlet 312 after being filtered. When the water tank 20 is a clean water tank, the input channel 21 is communicated with an external water source, so that the external water source flows into the clean water tank. When the cleaning device 60 equipped with the cleaning base station returns to the cleaning base station, the water filtered by the filtering device 40 will be conveyed into the cleaning device 60 through the conveying channel 301. Of course, in some embodiments, the input channel 21 can also be not communicated with the external water source, and the user can manually add water to the water tank. In some other embodiments, the cleaning base station further includes a water supply and drainage device, and the input channel 21 is communicated with the water supply and drainage device.

[0066] Further, the support part 41 includes a connecting section 412. An overflow hole 4122 is provided on the connecting section 412, and the overflow hole 4122 extends to the filtering part 42. At least one second opening 4121 is provided on the outer periphery of the connecting section 412, and the second opening 4121 is communicated with the overflow hole 4122. The water outlet end of the heating device 30 is communicated with at least one second opening 4121.

[0067] It can be understood that after the support part 41 is installed in the filtering chamber 31, after the water flowing out from the heating device 30 enters the filtering chamber 31 through the water inlet 311, the water will flow into the overflow hole 4122 from the second opening 4121 on the connecting section 412. Then the water flows to the filtering part 42 through the overflow hole 4122 for filtering and then flows out from the water outlet 312. In addition, in this embodiment, when there are multiple second openings 4121, at least one second opening 4121 is communicated with the water outlet end of the heating device 30, so as to avoid the inner wall surface of the filtering chamber 31 closing the second opening 4121, resulting in the water in the filtering chamber 31 not being able to enter the overflow hole 4122 from the second opening 4121, and finally causing the filtering device 40 to malfunction.

[0068] Further, a filtering chamber 31 is provided on the main body 10, and the support portion 41 is installed in the filtering chamber 31. The support portion 41 includes a connecting section 412, a first section 411, and a second section 413.

[0069] Wherein, a water passing channel 4123 is provided on the connecting section 412. The water passing channel 4123 extends to the filtering portion 42 and is communicated with the water outlet end of the heating device 30. Along the first direction (such as the X direction in the attached Figure 8 drawing), the first section is connected to the first end of the connecting section. A first sealing ring 4111 is provided on the outer periphery of the first section 411. The first sealing ring 4111 seals between the outer periphery of the first section 411 and the inner wall surface of the filtering chamber 31. Along the first direction, the second section 413 is connected to the outer periphery of the second end of the connecting section. A second sealing ring 4131 is provided on the outer periphery of the second section 413. The second sealing ring 4131 seals between the outer periphery of the second section 413 and the inner wall surface of the filtering chamber 31, and the communication position between the water passing channel 4123 and the water outlet end of the heating device 30 is located between the first sealing ring 4111 and the second sealing ring 4131.

[0070] Specifically, in this embodiment, the first section 411 and the second section 413 are used to support the connecting section 412. The water passing hole 4122 and the second opening 4121 form the water passing channel 4123. When the filtering device 40 is installed in the filtering chamber 31, the first sealing ring 4111 seals between the outer periphery of the first section 411 and the inner wall surface of the filtering chamber 31. At the same time, the second sealing ring 4131 seals between the outer periphery of the second section 413 and the inner wall surface of the filtering chamber 31, so that the water entering the filtering chamber 31 from the water inlet 311 can only enter the water passing hole 4122 through the second opening 4121, and cannot flow to the outside of the filtering chamber 31 along the outer peripheral surface of the first section 411, or flow into the water outlet 312 along the outer peripheral surface of the second section 413.

[0071] Further, the filtering portion 42 includes a filter net 421. In the existing technology, the filter net 421 is usually bonded to other components by glue. When the glue fails, the filter net 421 is likely to be separated from other components, ultimately resulting in the filter net 421 being unable to filter normally. In this embodiment, the filter net 421 and the support portion 41 are injection-molded as one body, or the filter net 421 is connected to the support portion 41 by ultrasonic welding, thereby improving the connection stability between the filter net 421 and the support portion 41. Optionally, the filter net 421 can be a non-woven filter net or a metal filter net; preferably, the mesh number of the non-woven filter net and the metal filter net is between 100 meshes and 200 meshes.

[0072] In some other embodiments, the filter net 421 is detachably connected to the support portion 41.

[0073] It can be understood that when the filter screen 421 is covered with a relatively large amount of impurities and scale, it is relatively difficult to thoroughly clean the filter screen 421. Therefore, when the filter screen 421 is detachably connected to the support portion 41, when maintaining the filtering device 40, the filter screen 421 can be detached and a new filter screen 421 can be directly replaced on the support portion 41, thereby improving the maintenance efficiency of the cleaning base station to a certain extent.

[0074] In some embodiments, the cleaning base station further includes a fixing member (not shown in the figure), and the filtering device 40 is connected to the main body 10 through the fixing member.

[0075] Specifically, a first connection hole is formed on the filtering device 40, a second connection hole adapted to the first connection hole is formed on the main body 10, the fixing member includes a bolt, and the bolt sequentially passes through the first connection hole and the second connection hole to fix the filtering device 40 on the main body 10. When it is necessary to disassemble the filtering device 40, only the bolt needs to be unscrewed, and the filtering device 40 can be disassembled from the main body 10.

[0076] In other embodiments, a card slot is provided on one of the filtering device 40 and the main body 10, and a buckle 44 adapted to the card slot is provided on the other.

[0077] Specifically, for example, the buckle 44 can be provided on the support portion 41, and the card slot can be provided in the filtering chamber 31. After the support portion 41 is pushed into the filtering chamber 31, the buckle 44 is clamped in the card slot, so that the support portion 41 is fixed in the filtering chamber 31. In a specific embodiment, the support portion 41 can rotate in the filtering chamber 31, and when the support portion 41 rotates to a specific position, the buckle 44 can be clamped in the card slot. At this time, the water inlet 311 of the filtering chamber 31 is communicated with the second opening 4121 on the connecting section 412.

[0078] Further, the filtering device further includes an operating portion 43, the operating portion 43 is connected to the support portion 41, the operating portion 43 has a first position where the support portion 41 is in a locked state under an external force, and a second position where the support portion is in an unlocked state; when the support portion 41 is in the locked state, the support portion 41 is connected to the main body 10, and the water outlet end of the heating device 30 is communicated with the filtering portion 42; when the support portion 41 is in the unlocked state, the support portion 41 can be disassembled from the main body 10.

[0079] Specifically, when the operation part 43 is moved to the first position by an external force, the support part 41 will not be locked to the main body 10 at this time, that is, the support part 41 will not be affected by the external force to separate from the main body 10. At the same time, when the operation part 43 is in the first position, the filtering part 42 must be communicated with the water outlet end of the heating device 30, so as to ensure that the filtering part 42 can work properly after the support part 41 is locked to the main body 10. When the operation part 43 is located at the second position under the action of an external force, the support part 41 can be disassembled from the main body 10, which is convenient for maintaining the filtering device 40. In a specific embodiment, when a rotary buckle 44 is provided on the support part 41 and a clamping groove is provided on the main body 10, a locking mark corresponding to the first position and an unlocking mark corresponding to the second position are further provided on the outer peripheral surface of the main body 10. That is, by applying force to the operation part 43, the support part 41 and the filtering part 42 can be driven to rotate in the filtering chamber 31. When the operation part 43 rotates to the locking mark, the rotary buckle 44 is clamped in the clamping groove, and the operation part 43 reaches the first position. When the operation part 43 rotates to the unlocking mark, the rotary buckle 44 is separated from the clamping groove, and the operation part 43 reaches the second position.

[0080] Further, the filtering device 40 is installed in the main body 10 from the outside of the main body 10 to the direction close to the outer peripheral surface where the filtering device 40 is installed.

[0081] It can be understood that there is an installation surface for installing the filtering device 40 on the outer peripheral surface. When it is necessary to install the filtering device 40, in some embodiments, it can be installed along the direction perpendicular to and close to this installation surface; in other embodiments, the filtering device 40 can be installed on the main body 10 from the outside of the main body 10 along the direction inclined to and close to this installation surface. Similarly, when disassembling the filtering device 40 from the main body 10, in some embodiments, the filtering device 40 can be disassembled along the direction perpendicular to and away from this installation surface; in other embodiments, the filtering device 40 can be disassembled along the direction inclined to and away from this installation surface. According to the different installation surfaces of the filtering device 40 on the outer peripheral surface, different installation or extraction directions can be designed, so as to facilitate the rapid assembly of the filtering device 40 and the main body 10.

[0082] Further, the outer peripheral surface of the main body includes a first surface 11, and a receiving groove 101 is formed on the first surface 11 for receiving a cleaning device. The filtering device 40 is installed on the main body 10 from the first surface 11.

[0083] It can be understood that the first opening is provided on the first surface 11. The outer peripheral surface of the main body 10 further includes a second surface 12 disposed opposite to the first surface 11, a first side surface 13 and a second side surface 14 that are oppositely connected between the first surface 11 and the second surface 12, as well as a top surface 15 and a bottom surface 16. Since the cleaning base station is usually placed at the corner of a home, the bottom surface 16, the second surface 12, the first side surface 13 and the second side surface 14 are easily blocked by the corner. And because the first surface 11 has the accommodating groove 101, to ensure that the cleaning device 60 can return to the accommodating groove 101, the first surface 11 is usually not blocked. Therefore, it is a relatively optimal implementation manner to install the filtering device 40 on the main body from the first surface 11, which can improve the user experience to a certain extent.

[0084] Of course, in some other embodiments, the filtering device 40 can also be installed on the main body 10 by the second surface 12, the first side surface 13, the second side surface 14, the top surface 15 or the bottom surface 16. For example, the outer peripheral surface of the main body 10 further includes the first side surface 13 and the second side surface 14. The first side surface 13 and the second side surface 14 are oppositely connected to both sides of the first surface 11 along the second direction (such as the Figure 4 Y direction in the attachment), and the filtering device is installed on the main body 10 by the first side surface 13 or the second side surface 14.

[0085] In a specific embodiment, as shown in the attachment Figure 3 the filtering device 40 can be installed on the main body 10 by the first side surface 13 of the main body 10, that is, the first opening of the filtering chamber 31 is located on the first side surface 13. When the filtering device 40 is disassembled from the filtering chamber 31, the filtering device 40 is withdrawn in the direction from the inside of the filtering chamber 31 to the outside of the main body 10. The side-mounted or extraction method can avoid the filtering device 40 being blocked by the corner to a certain extent.

[0086] Furthermore, the cleaning base station further includes a pump body 50, a controller (not shown in the figure) and a container (not shown in the figure). The pump body 50 is disposed on the main body 10, and the pump body 50 is connected between the input channel 21 and the heating device 30. The controller is disposed on the main body 10, and the controller is electrically connected to the heating device 30. The container is disposed on the main body 10, and the container is used to put the descaling agent in the container into the input channel 21 and / or the heating device 30.

[0087] Specifically, the pump body 50 is arranged between the water outlet end of the water tank 20 and the water inlet tank of the heating device 30 for pumping the water in the water tank 20 into the heating device 30. The controller is at least used to control the heating of the heating device 30 and control the connection between the water tank 20 and the external water circuit. In a specific embodiment, both the pump body 50 and the container are electrically connected to the controller. When self-cleaning of the cleaning base station is required, the controller can control the container to put the descaling agent in the container into the water tank 20. Subsequently, the controller controls the water tank 20 to inject water, controls the pump body 50 to pump the mixed solution of water and the descaling agent in the water tank 20 into the heating device 30, and controls the heating device 30 to heat. Subsequently, the heated mixed solution sequentially passes through the water outlet end of the heating device 30, the water inlet 311 of the filtering chamber 31, the second opening 4121 of the supporting part 41, the flow-through hole 4122, the filtering part 42, and the water outlet 312 of the filtering chamber 31 to dissolve the water scale in the conveying channel 301 of the heating device 30 and the filtering device 40. Finally, the sewage with water scale is discharged through the conveying channel 301, so that the cleaning base station completes self-cleaning.

[0088] On the other hand, the present application discloses a control method for a cleaning base station. The control method for the cleaning base station is executed by the above-mentioned cleaning base station. As shown in the appendix Figure 9 The control method for the cleaning base station includes: when the cleaning base station receives a self-cleaning signal, putting a descaling agent into the water tank 20 and / or the heating device 30 to perform self-cleaning on the water circuit of the cleaning base station.

[0089] It can be understood that after the cleaning base station works for a certain period of time, although a filtering device 40 is provided in the cleaning base station, the water scale generated after the heating device 30 heats water may adhere to the filtering device 40, the heating device 30, and the water circuit pipeline. Therefore, the cleaning base station needs to have the ability of self-cleaning to remove the water scale adhering to the filtering device 40, the heating device 30, and the water circuit pipeline. In this embodiment, when the controller of the cleaning base station receives a self-cleaning signal, the controller controls the container to put the descaling agent into the water tank 20 and / or the heating device 30. Subsequently, the heating device 30 heats the mixed liquid of water and the descaling agent. When the mixed liquid encounters the water scale in the water circuit pipeline, the water scale is dissolved in the mixed solvent and finally flows out of the cleaning base station through the conveying channel 301, so as to achieve the purpose of self-cleaning. Of course, in some embodiments, when the controller of the cleaning base station receives a self-cleaning signal, the controller sends out a warning signal to prompt the external personnel of the cleaning base station to put the descaling agent into the water tank 20 and / or the heating device 30. After the external personnel put the descaling agent into the water tank 20 and / or the heating device 30, the cleaning base station starts self-cleaning.

[0090] Further, the self-cleaning signal includes at least one of the following: the cleaning base station has run for a predetermined period, a free self-cleaning signal sent to the cleaning base station externally, and the detected scale thickness in the heating device 30 has reached a predetermined thickness.

[0091] In some embodiments, the controller also has the function of timing and / or recording the number of times the cleaning base station delivers water to the cleaning device 60. When the cleaning base station has worked for a predetermined time, for example, it can be set to 3 months, 6 months or 8 months, the controller will control the cleaning base station to start self-cleaning, so that the cleaning base station starts self-cleaning; or when the number of times the cleaning base station delivers water to the cleaning device 60 reaches a certain number, the controller will control the cleaning base station to start self-cleaning. In some embodiments, a sensor for detecting the scale thickness is provided in the heating device 30. When the sensor detects that the scale thickness has reached a predetermined thickness, the sensor sends an electrical signal to the controller, so that the controller controls the cleaning base station to start self-cleaning. Of course, in some embodiments, when the cleaning base station has run for a predetermined period and / or the detected scale thickness in the heating device 30 has reached a predetermined thickness, the controller will send a prompt signal to the control program on the external terminal device. After seeing the prompt signal on the control program, an external person can send a self-cleaning signal to the cleaning base station through the control program, so that the cleaning base station starts self-cleaning. It can be understood that since the cleaning base station has different sizes, the size of the heating device 30 is also different. In some large-sized heating devices 30, a relatively thick scale thickness is required to affect the heating device 30, while in some small-sized heating devices 30, a relatively thin scale thickness will affect the heating device 30. Therefore, no specific limitation is made on the predetermined thickness in this embodiment.

[0092] Further, the steps of adding a descaling agent into the water tank 20 for self-cleaning the cleaning base station include: injecting a mixed solution composed of water and a descaling agent in a predetermined ratio into the water tank 20; extracting the mixed solution in the water tank 20 into the heating device 30 at a predetermined flow rate v; heating the heating device 30 to a predetermined temperature T; and if the mixed solution in the water tank 20 reaches a preset amount, controlling the cleaning base station to stop working.

[0093] In a specific embodiment, when the controller receives a self-cleaning signal, the controller controls the container to put a certain amount of scale remover into the water tank 20. At the same time, the controller controls the water tank 20 to be connected to the external water circuit, so that the water in the external water circuit flows into the water tank 20. When the water and the scale remover reach a predetermined ratio, the controller controls the disconnection of the external water circuit from the water tank 20. After that, the controller controls the pump body 50 to extract the mixed solution in the water tank 20 into the heating device 30 at a predetermined flow rate v. At the same time, the controller controls the heating device 30 to heat up to a predetermined temperature T. The heated mixed solution dissolves the scale in the heating device 30 and the conveying channel 301, and then flows out through the conveying channel 301. When the mixed solution in the water tank 20 reaches a predetermined amount, the controller controls the cleaning base station to stop working, and the self-cleaning of the cleaning base station is completed. The predetermined amount can be 0. In some embodiments, since there is a lot of scale on the filtering device 40, it is difficult to clean the scale on the filtering device 40 by means of self-cleaning. Therefore, it is necessary to disassemble the filtering device 40 and further process the scale on the filtering device 40. It can be understood that when the cleaning base station has different sizes, the ratio of water to scale remover required for self-cleaning is not the same. Therefore, the present embodiment does not make a specific limitation on the predetermined ratio.

[0094] Further, when the cleaning base station receives a self-cleaning signal, the flow rate of the mixed solution in the water tank 20 being extracted into the heating device 30 is lower than the flow rate when the cleaning base station does not receive a self-cleaning signal.

[0095] It can be understood that since the cleaning base station is in a self-cleaning state at this time, it is necessary to make the scale remover and water in the water tank 20 fully mixed, and at the same time fully heat the mixed solution in the heating device 30. Therefore, the suction speed of the pump body 50 for the water tank should be reduced to a certain extent at this time, so as to improve the self-cleaning effect of the cleaning base station.

[0096] Similarly, in order to improve the effect of the mixed solution in dissolving the scale and impurities in the water pipeline. When the cleaning base station receives a self-cleaning signal, the heating temperature of the heating device 30 is higher than the heating temperature when the cleaning base station does not receive a self-cleaning signal. That is, when the cleaning base station is in a self-cleaning state, the temperature of the heated mixed solution should be increased as much as possible, so as to improve the reaction efficiency of the mixed solution with the scale and impurities in the water pipeline.

[0097] Further, the predetermined flow rate v satisfies the relationship: 200 ml / min ≤ v ≤ 400 ml / min.

[0098] Specifically, during the self-cleaning process, since the heating device 30 needs to heat the mixed solution, the suction speed of the pump body 50 should be set relatively small to ensure that the heating device 30 can fully heat the mixed solution. Generally speaking, during the process of the cleaning base station delivering water to the cleaning device 60, the suction rate v of the pump body 50 for the water tank 20 satisfies the relational expression 400 ml / min ≤ v ≤ 500 ml / min. At this time, since the temperature at which the heating device 30 needs to heat the water is relatively low, the suction rate of the pump body 50 can be set relatively high. In addition, during the self-cleaning process, when v is less than 200 ml / min, the suction rate of the pump body 50 is too low at this time, resulting in a relatively long self-cleaning process of the cleaning base station; when v is greater than 400 ml / min, the suction rate of the pump body 50 is too high at this time, which may cause the mixed liquid in the heating device 30 to fail to reach the specified temperature, thereby reducing the scale-dissolving ability of the mixed liquid. The value of v can be 200 ml / min, 250 ml / min, 300 ml / min, 350 ml / min, and 400 ml / min.

[0099] Furthermore, the predetermined temperature T satisfies the relational expression: 60°C ≤ T ≤ 70°C.

[0100] During non-self-cleaning, the heating temperature of the heating device 30 is usually set between 50°C and 60°C. At this time, the hot water is mainly used to be delivered to the cleaning device 60, so as to improve the cleaning ability of the cleaning device 60 for the cleaning parts. During the self-cleaning of the cleaning base station, the heating temperature of the heating device 30 needs to reach 60°C to 70°C. At this time, the mixed solution at a relatively high temperature can fully react with the scale, and then dissolve the scale, improving the self-cleaning effect of the cleaning base station. The value of T can be 60°C, 62°C, 64°C, 66°C, 68°C, and 70°C.

[0101] In summary, the cleaning base station and the control method of the cleaning base station of the present application at least have the following beneficial effects:

[0102] (1) By providing the filtering device 40 on the main body 10, it is possible to prevent the water channels in the cleaning base station or the cleaning device 60 from being blocked by scale and impurities, ultimately resulting in the abnormal operation of the cleaning base station or the cleaning device 60.

[0103] (2) A filter chamber 31 is provided on the conveying channel 301. The filter chamber 31 has a first opening located outside the main body 10. The support part 41 is detachably connected to the inside of the filter chamber 31 through the first opening. When the support part 41 is connected to the filter chamber 31, the filtering part 42 is located inside the filter chamber 31. This means that the water flowing out of the heating device 30 needs to enter the filter chamber 31 through the water inlet 311 of the filter chamber 31. Then the water passes through the support part 41 and the filtering part 42, and finally flows out through the water outlet 312 of the filter chamber 31, so as to make the heated water flow in a directional manner and improve the use efficiency of the filtering part 42.

[0104] (3) A first sealing ring 4111 is provided on the first section 411, and a second sealing ring 4131 is provided on the second section 413. When the support part 41 is connected to the inside of the filter chamber 31, the first sealing ring 4111 abuts between the outer peripheral surface of the first section 411 and the inner wall surface of the filter chamber 31, and the second sealing ring 4131 abuts between the outer peripheral surface of the first section 411 and the inner wall surface of the filter chamber 31, so as to prevent the water flowing into the filter chamber 31 from flowing to the outside of the cleaning base station through the outer peripheral surface of the first section 411 or flowing to the water outlet 312 of the filter chamber 31 through the outer peripheral surface of the second section 413.

[0105] (4) The control method of the cleaning base station of the present application can, to a certain extent, improve the service life of the cleaning base station, and can, to a certain extent, improve the maintenance cycle of the cleaning base station and reduce the maintenance cost of the cleaning base station.

[0106] For the sake of convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features.

Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...".
