[0015] When the support is in the locked state, the support is connected to the main body, and the water outlet of the heating device is connected to the filter; when the support is in the unlocked state, the support can be detached from the main body.

[0016] Furthermore, the support includes a connecting section, on which a flow hole is provided, the flow hole extending to the filter section, and at least one second opening is provided on the outer periphery of the connecting section, the second opening communicating with the flow hole, and the water outlet of the heating device communicating with at least one second opening.

[0017] Furthermore, the main body is provided with a filter chamber, the filter device is installed in the filter chamber, and the support portion includes:

A second sealing ring is provided on the outer periphery of the second segment, and the second sealing ring seals between the outer periphery of the second segment and the inner wall of the filter chamber.

[0021] Furthermore, the filtering section includes a filter screen;

Furthermore, thanks to the filtration device, most impurities and scale in the cleaning base station's water path are deposited there. Regular cleaning of the filtration device during maintenance can largely prevent blockage of the water pipes in the cleaning base station. In addition, the cleaning base station design of this application ensures that the water input from the cleaning base station to the cleaning equipment is free of impurities and scale, thus preventing blockage of the water pipes within the cleaning equipment.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0047] As mentioned in the background section, if excessive scale or impurities accumulate in the water pipes of the cleaning base station, it will cause the cleaning base station to malfunction. Current technology typically involves disassembling the cleaning base station to clean its water pipes, a cumbersome and costly process. However, when water containing impurities and scale enters the cleaning equipment 60 used with the cleaning base station, the impurities and scale may also clog the water pipes of the cleaning equipment 60, causing it to malfunction. Furthermore, due to the small size of the cleaning equipment 60 and the compact arrangement of its internal components, maintaining its water pipes is difficult. The cleaning equipment 60 can be, for example, a robotic vacuum cleaner, a vacuum cleaner, or a sweeping robot.

[0048] To avoid the above problems, see Figures 1 to 8 As shown, according to an embodiment of this application, a clean base station is provided, which includes a main body 10, an input channel 21, a heating device 30, and a filtering device 40.

[0049] The input channel 21 is located on the main body 10, the heating device 30 is located on the main body 10 to heat the water in the input channel 21, and the filtration device 40 is installed on the main body 10 to filter the water flowing out of the heating device 30.

[0050] Specifically, in this embodiment, input channel 21 is used to supply water to heating device 30. The water heated by heating device 30 flows into filter device 40. When scale forms in heating device 30 or when the water in heating device 30 contains impurities, the impurities and scale are filtered out by filter device 40, thus preventing scale and impurities from clogging the water path of the cleaning base station. Simultaneously, thanks to the filter device 40, most impurities or scale in the water path of the cleaning base station are deposited at the filter device 40. During maintenance of the cleaning base station, regular cleaning of the filter device 40 can largely prevent blockage of the water path pipes in the cleaning base station. Furthermore, the cleaning base station configuration in this embodiment ensures that the water input from the cleaning base station to the cleaning equipment 60 is free of impurities and scale, thereby preventing blockage of the water path pipes within the cleaning equipment 60.

[0051] Furthermore, the filter device 40 includes a support portion 41 and a filter portion 42. The filter device 40 is detachably connected to the main body 10, and the filter portion 42 is connected to the support portion 41 for filtering the water flowing out of the heating device 30.

[0052] In this embodiment, the support part 41 provides support for the filter part 42, preventing the filter part 42 from being detached from the main body 10 under external force during filtration. The filter device 40 is detachably connected to the main body 10 to facilitate regular maintenance of the filter part 42 and prevent scale and impurities from clogging the filter part 42, thus preventing the filter device 40 from malfunctioning. In this embodiment, the filter part 42 is used to filter the water flowing out of the heating device 30. When the heating device 30 heats the water, causing scale to appear in the water, or when there are impurities in the water inside the heating device 30, the filter part 42 is used to filter the scale and impurities in the water.

[0053] In some embodiments, the heating device 30 is connected to the outlet of the water tank 20, and the outlet of the heating device 30 is connected to a conveying channel 301. A filter chamber 31 is also provided on the conveying channel 301. The filter chamber 31 has a first opening located outside the main body 10. The inner wall of the filter chamber 31 is provided with an inlet 311 and an outlet 312. The filter device 40 is detachably connected to the first opening, that is, the filter device 40 is installed on the main body 10 from the outer peripheral surface of the main body 10. The filter part 42 is located in the filter chamber 31 for filtering the water flowing in from the inlet 311.

[0054] Specifically, to improve the assembly efficiency of the support part 41, the filter chamber 31 has a first opening located outside the main body 10. That is, the support part 41 can be directly installed into the filter chamber 31 from the outside of the main body 10, or the support part 41 can be removed from the filter chamber 31 from the outside of the main body 10, so as to facilitate maintenance of the filter device 40. On the other hand, when the support part 41 is installed in the filter chamber 31, the filter part 42 is also located in the filter chamber 31, and the water flowing into the filter chamber 31 from the inlet 311 needs to be filtered by the filter part 42 before flowing out from the outlet 312. That is, the filter chamber 31 in this embodiment also has a positioning effect so that the filter part 42 can properly filter the water flowing into the filter chamber 31.

[0055] It is worth mentioning that the water tank 20 can be either a sewage tank or a clean water tank. When the water tank is a sewage tank, the sewage in the sewage tank is heated, evaporated, and condensed by the heating device 30 and collected in the return tank of the cleaning base station. Subsequently, the sewage remaining in the sewage tank is filtered and flows out through the outlet 312. When the water tank 20 is a clean water tank, the input channel 21 is connected to an external water source, allowing external water to flow into the clean water tank. When the cleaning equipment 60 equipped with the cleaning base station returns to the cleaning base station, the water filtered by the filtration device 40 is transported to the cleaning equipment 60 through the conveying channel 301. Of course, in some embodiments, the input channel 21 may not be connected to an external water source, and the user can manually add water to the water tank. In some embodiments, the cleaning base station also includes a water supply and drainage device, and the input channel 21 is connected to the water supply and drainage device.

[0056] Furthermore, the support part 41 includes a connecting section 412, on which a flow hole 4122 is provided. The flow hole 4122 extends to the filter part 42. At least one second opening 4121 is provided on the outer periphery of the connecting section 412. The second opening 4121 communicates with the flow hole 4122. The water outlet end of the heating device 30 communicates with at least one second opening 4121.

[0057] Understandably, after the support 41 is installed in the filter chamber 31, water flowing from the heating device 30 enters the filter chamber 31 through the inlet 311. The water then flows through the second opening 4121 on the connecting section 412 into the flow passage 4122. Afterward, the water flows through the flow passage 4122 to the filter section 42 for filtration and then flows out through the outlet 312. Furthermore, in this embodiment, when there are multiple second openings 4121, at least one second opening 4121 is connected to the outlet end of the heating device 30. This prevents the inner wall of the filter chamber 31 from sealing the second opening 4121, thus preventing water in the filter chamber 31 from entering the flow passage 4122 and ultimately causing the filter device 40 to malfunction.

[0058] Furthermore, a filter chamber 31 is provided on the main body 10, and a support part 41 is installed in the filter chamber 31. The support part 41 includes a connecting section 412, a first section 411, and a second section 413.

[0059] The connecting section 412 is provided with a water passage 4123, which extends to the filter section 42 and is connected to the outlet of the heating device 30. Along the first direction (as shown in the attached diagram) Figure 8 In the X direction, the first segment 411 is connected to the first end of the connecting segment. A first sealing ring 4111 is provided on the outer periphery of the first segment 411, and the first sealing ring 4111 seals between the outer periphery of the first segment 411 and the inner wall surface of the filter chamber 31. In the first direction, the second segment 413 is connected to the outer periphery of the second end of the connecting segment. A second sealing ring 4131 is provided on the outer periphery of the second segment 413, and the second sealing ring 4131 seals between the outer periphery of the second segment 413 and the inner wall surface of the filter chamber 31.

[0060] Specifically, in this embodiment, the first segment 411 and the second segment 413 provide support for the connecting segment 412, and the flow hole 4122 and the second opening 4121 form a water passage 4123. When the filter device 40 is installed in the filter chamber 31, the first sealing ring 4111 seals between the outer periphery of the first segment 411 and the inner wall of the filter chamber 31, while the second sealing ring 4131 seals between the outer periphery of the second segment 413 and the inner wall of the filter chamber 31. This ensures that water entering the filter chamber 31 from the inlet 311 can only enter the flow hole 4122 through the second opening 4121, and cannot flow along the outer periphery of the first segment 411 to the outside of the filter chamber 31, or along the outer periphery of the second segment 413 to the outlet 312.

[0061] Furthermore, the filter section 42 includes a filter screen 421. In the prior art, the filter screen 421 is usually glued to other components. However, glue adhesion can cause the filter screen 421 to easily detach from other components when the glue fails, ultimately leading to the filter screen 421 failing to filter properly. In this embodiment, the filter screen 421 is injection molded integrally with the support section 41, or the filter screen 421 is connected to the support section 41 by ultrasonic welding, thereby improving the connection stability between the filter screen 421 and the support section 41. Optionally, the filter screen 421 can be a non-woven fabric filter screen or a metal filter screen; preferably, the mesh count of the non-woven fabric filter screen and the metal filter screen is between 100 and 200 mesh.

[0062] In other embodiments, the filter 421 is detachably connected to the support 41.

[0063] It is understandable that when the filter screen 421 is covered with a lot of impurities and scale, it is difficult to thoroughly clean the filter screen 421. Therefore, when the filter screen 421 is detachably connected to the support part 41, when maintaining the filter device 40, the filter screen 421 can be removed and a new filter screen 421 can be directly replaced on the support part 41, thereby improving the maintenance efficiency of the cleaning base station to a certain extent.

[0064] In some embodiments, the clean base station also includes a fixing member (not shown), through which the filter device 40 is connected to the main body 10.

[0065] Specifically, the filter device 40 has a first connecting hole, and the main body 10 has a second connecting hole that matches the first connecting hole. The fasteners include bolts, which pass through the first connecting hole and the second connecting hole in sequence to fix the filter device 40 to the main body 10. When it is necessary to disassemble the filter device 40, simply unscrew the bolts to remove the filter device 40 from the main body 10.

[0066] In other embodiments, a slot is provided on one of the filter device 40 and the main body 10, and a buckle 44 adapted to the slot is provided on the other.

[0067] Specifically, for example, the buckle 44 can be disposed on the support part 41, and the slot can be disposed in the filter chamber 31. When the support part 41 is pushed into the filter chamber 31, the buckle 44 is engaged in the slot, thereby fixing the support part 41 in the filter chamber 31. In a specific embodiment, the support part 41 can rotate in the filter chamber 31, and the buckle 44 can only be engaged in the slot when the support part 41 rotates to a specific position. At this time, the water inlet 311 of the filter chamber 31 is connected to the second opening 4121 on the connecting section 412.

[0068] Furthermore, the filtration device also includes an operation unit 43, which is connected to the support unit 41. The operation unit 43 has a first position where the support unit 41 is locked under external force, and a second position where the support unit is unlocked. When the support unit 41 is locked, it is connected to the main body 10, and the water outlet of the heating device 30 is connected to the filtration unit 42. When the support unit 41 is unlocked, it can be detached from the main body 10.

[0069] Specifically, when the operating 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, meaning the support part 41 will not be detached from the main body 10 by external force. Simultaneously, when the operating part 43 is in the first position, the filter part 42 is necessarily connected to the water outlet of the heating device 30, thus ensuring that the filter part 42 can function normally after the support part 41 is locked to the main body 10. When the operating part 43 is in the second position by an external force, the support part 41 can be detached from the main body 10, facilitating maintenance of the filter device 40. In a specific embodiment, when the support part 41 is provided with a rotating buckle 44 and the main body 10 is provided with a slot, the outer peripheral surface of the main body 10 is also provided with a locking mark corresponding to the first position and an unlocking mark corresponding to the second position. That is, when force is applied to the operating part 43, the support part 41 and the filter part 42 can be driven to rotate in the filter chamber 31. When the operating part 43 rotates to the locking mark, the rotating buckle 44 is engaged in the slot and the operating part 43 reaches the first position. When the operating part 43 rotates to the unlocking mark, the rotating buckle 44 separates from the slot and the operating part 43 reaches the second position.

[0070] Furthermore, the filter device 40 is installed inside the body 10 from the outside of the body 10 toward the outer peripheral surface on which the filter device 40 is installed.

[0071] It is understood that the outer peripheral surface has a mounting surface for mounting the filter device 40. When the filter device 40 needs to be installed, in some embodiments, it can be installed in a direction perpendicular to and close to the mounting surface; in other embodiments, the filter device 40 can be mounted on the body 10 from the outside of the body 10 in a direction inclined to and close to the mounting surface. Similarly, when removing the filter device 40 from the body 10, in some embodiments, the filter device 40 can be removed in a direction perpendicular to and away from the mounting surface; in other embodiments, the filter device 40 can be removed in a direction inclined to and away from the mounting surface. Depending on the way the filter device 40 is mounted on different mounting surfaces on the outer peripheral surface, different installation or removal directions can be designed to facilitate the rapid assembly of the filter device 40 and the body 10.

[0072] Furthermore, the outer peripheral surface of the main body includes a first surface 11, and the first surface 11 has a receiving groove 101 for receiving cleaning equipment. The filter device 40 is mounted on the main body 10 from the first surface 11.

[0073] It is understood that the first opening is located on the first surface 11, and the outer peripheral surface of the main body 10 also includes a second surface 12 opposite to the first surface 11, a first side surface 13 and a second side surface 14 connecting 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 in 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. However, since the first surface 11 has a receiving groove 101, in order to ensure that the cleaning device 60 can return to the receiving groove 101, the first surface 11 is usually not blocked. Therefore, it is a better implementation method for the filter device 40 to be installed on the main body by the first surface 11, which can improve the user experience to a certain extent.

[0074] Of course, in some other embodiments, the filter device 40 may also be mounted on the 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 body 10 also includes the first side surface 13 and the second side surface 14, which are connected relative to each other on the first surface 11 along a second direction (as shown in the attached figure). Figure 4 On both sides (in the Y direction), the filter device is installed on the main body 10 by the first side 13 or the second side 14.

[0075] In one specific embodiment, as shown in the appendix Figure 3 As shown, the filter device 40 can be installed on the main body 10 from the first side 13 of the main body 10, that is, the first opening of the filter chamber 31 is located on the first side 13. When the filter device 40 is removed from the filter chamber 31, the filter device 40 is pulled out along the direction from the inside of the filter chamber 31 to the outside of the main body 10. The side installation or extraction method can avoid the filter device 40 being blocked by the corner of the wall to a certain extent.

[0076] Furthermore, the cleaning base station also 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 is connected between the input channel 21 and the heating device 30. The controller is disposed on the main body 10 and is electrically connected to the heating device 30. The container is disposed on the main body 10 and is used to add the descaling agent in the container into the input channel 21 and / or the heating device 30.

[0077] Specifically, the pump body 50 is located between the outlet end of the water tank 20 and the inlet tank of the heating device 30 to draw water from the water tank 20 into the heating device 30. The controller is used at least to control the heating of the heating device 30 and to control the connection between the water tank 20 and the external water circuit. In one 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 add 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 mixture of water and descaling agent in the water tank 20 into the heating device 30, and controls the heating device 30 to heat. After heating, the mixture passes sequentially through the outlet of the heating device 30, the inlet 311 of the filter chamber 31, the second opening 4121 of the support part 41, the flow hole 4122, the filter part 42, and the outlet 312 of the filter chamber 31 to dissolve the scale in the conveying channel 301 of the heating device 30 and the filter device 40. Finally, the wastewater containing scale is discharged through the conveying channel 301, thereby enabling the cleaning base station to complete self-cleaning.

[0078] On the other hand, this application discloses a control method for a clean base station, which is implemented using the aforementioned clean base station, as shown in the attached figure. Figure 9 As shown, the control method of the cleaning base station includes: when the cleaning base station receives a self-cleaning signal, adding descaling agent into the water tank 20 and / or heating device 30 to perform self-cleaning of the water circuit of the cleaning base station.

[0079] It is understandable that after the cleaning base station has been operating for a certain period of time, although a filter device 40 is installed inside the cleaning base station, scale generated by the heating device 30 after heating water may adhere to the filter device 40, the heating device 30, and the water pipes. Therefore, the cleaning base station needs to have self-cleaning capabilities to remove the scale adhering to the filter device 40, the heating device 30, and the water pipes. In this embodiment, when the controller of the cleaning base station receives a self-cleaning signal, the controller controls the container to add descaling agent to the water tank 20 and / or the heating device 30. Subsequently, the heating device 30 heats the mixture of water and descaling agent. When the mixture encounters the scale in the water pipes, it dissolves the scale in the mixed solvent and finally flows out of the cleaning base station through the conveying channel 301, thereby achieving the purpose of self-cleaning. Of course, in some embodiments, when the controller of the cleaning base station receives the self-cleaning signal, the controller sends an external warning signal to prompt external personnel to add descaling agent into the water tank 20 and / or heating device 30. After the external personnel add descaling agent into the water tank 20 and / or heating device 30, the cleaning base station begins self-cleaning.

[0080] Furthermore, the self-cleaning signal includes: the cleaning base station operating for a predetermined period, a free self-cleaning signal sent from outside to the cleaning base station, and the detection that the scale thickness in the heating device 30 reaches at least one of the predetermined thicknesses.

[0081] 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 operates for a predetermined time, such as 3 months, 6 months, or 8 months, the controller will control the cleaning base station to start self-cleaning. Alternatively, 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 scale thickness is provided in the heating device 30. When the sensor detects that the scale thickness reaches a predetermined thickness, the sensor sends an electrical signal to the controller, thereby causing the controller to control the cleaning base station to start self-cleaning. Of course, in some embodiments, when the cleaning base station operates for a predetermined period and / or detects that the scale thickness in the heating device 30 reaches a predetermined thickness, the controller will send a prompt signal to the control program on an external terminal device. After seeing the prompt signal on the control program, external personnel can send a self-cleaning signal to the cleaning base station through the control program, thereby causing the cleaning base station to start self-cleaning. It is understandable that since the cleaning base stations have different sizes, the size of the heating device 30 is also different. In some large-sized heating devices 30, the scale thickness needs to be thicker to affect the heating device 30, while in small-sized heating devices 30, the scale thickness is thinner and will affect the heating device 30. Therefore, this embodiment does not make a specific limitation on the predetermined thickness.

[0082] Furthermore, the step of adding descaling agent into water tank 20 to perform self-cleaning of the cleaning base station includes: injecting a mixed solution of water and descaling agent in a predetermined ratio into water tank 20; drawing the mixed solution in water tank 20 into heating device 30 at a predetermined flow rate v; heating device 30 to a predetermined temperature T; and controlling the cleaning base station to stop working if the mixed solution in water tank 20 reaches a preset amount.

[0083] In one specific embodiment, after receiving a self-cleaning signal, the controller controls the container to add a certain amount of descaling agent to the water tank 20. Simultaneously, the controller connects the water tank 20 to an external water supply line, allowing water from the external line to flow into the water tank 20. When the water and descaling agent reach a predetermined ratio, the controller disconnects the external water supply line from the water tank 20. Then, the controller controls the pump 50 to draw the mixed solution from the water tank 20 into the heating device 30 at a predetermined flow rate v. Simultaneously, the controller controls the heating device 30 to heat 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, completing the self-cleaning of the cleaning base station. The predetermined amount can be 0. In some embodiments, because there is a large amount of scale on the filter device 40, it is difficult to clean the scale completely using self-cleaning. Therefore, it is necessary to disassemble the filter device 40 and further treat the scale on it. It is understood that the ratio of water to descaling agent required for self-cleaning varies depending on the size of the cleaning base station. Therefore, this embodiment does not impose a specific limit on the predetermined ratio.

[0084] Furthermore, when the cleaning base station receives the self-cleaning signal, the flow rate of the mixed solution in the water tank 20 drawn into the heating device 30 is lower than the flow rate when the cleaning base station does not receive the self-cleaning signal.

[0085] Understandably, since the cleaning base station is in a self-cleaning state at this time, it is necessary to ensure that the descaling agent in the water tank 20 is fully mixed with the water, and at the same time, to fully heat the mixed solution in the heating device 30. Therefore, the pumping speed of the pump body 50 to the water tank should be reduced to a certain extent to improve the self-cleaning effect of the cleaning base station.

[0086] Similarly, to improve the effectiveness of the mixed solution in dissolving scale and impurities in the water pipes, the heating temperature of the heating device 30 is higher when the cleaning base station receives a self-cleaning signal than when the cleaning base station does not receive a self-cleaning signal. That is, when the cleaning base station is in self-cleaning mode, the temperature of the heated mixed solution should be increased as much as possible to improve the reaction efficiency between the mixed solution and the scale and impurities in the water pipes.

[0087] Furthermore, the predetermined flow rate v satisfies the following relationship: 200ml / min≤v≤400ml / min.

[0088] 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 low to ensure that the heating device 30 can fully heat the mixed solution. Generally, during the process of the cleaning base station supplying water to the cleaning equipment 60, the suction rate v of the pump body 50 to the water tank 20 satisfies the relationship 400ml / min≤v≤500ml / min. Since the heating device 30 needs to heat the water to a relatively low temperature, the suction rate of the pump body 50 can be set higher. Furthermore, during the self-cleaning process, when v is less than 200ml / min, the suction rate of the pump body 50 is too low, resulting in a longer self-cleaning process for the cleaning base station; while when v is greater than 400ml / min, the suction rate of the pump body 50 is too high, which may prevent the mixed liquid in the heating device 30 from reaching the specified temperature, thus reducing the ability of the mixed liquid to dissolve scale. The value of v can be 200ml / min, 250ml / min, 300ml / min, 350ml / min, or 400ml / min.

[0089] Furthermore, the predetermined temperature T satisfies the relationship: 60℃≤T≤70℃.

[0090] In non-self-cleaning mode, the heating temperature of the heating device 30 is typically set between 50°C and 60°C. The hot water is primarily supplied to the cleaning equipment 60, thereby enhancing its cleaning capabilities. However, during self-cleaning of the base station, the heating temperature of the heating device 30 needs to reach 60°C to 70°C. At this higher temperature, the mixed solution can fully react with the scale, dissolving it and improving the self-cleaning effect of the base station. The value of T can be 60°C, 62°C, 64°C, 66°C, 68°C, or 70°C.

[0091] In summary, the clean base station and its control method of this application have at least the following beneficial effects:

[0092] (1) By setting a filter device 40 on the main body 10, scale and impurities are prevented from clogging the water path in the cleaning base station or cleaning equipment 60, which would eventually cause the cleaning base station or cleaning equipment 60 to malfunction.

[0093] (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 filter chamber 31 through the first opening. When the support part 41 is connected to the filter chamber 31, the filter 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 inlet 311 of the filter chamber 31. Then the water passes through the support part 41 and the filter part 42, and finally flows out through the outlet 312 of the filter chamber 31, thereby causing the heated water to flow in a directional manner and improving the efficiency of the filter part 42.

[0094] (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 filter chamber 31, the first sealing ring 4111 abuts against 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 against the outer peripheral surface of the first section 411 and the inner wall surface of the filter chamber 31, thereby preventing water flowing into the filter chamber 31 from flowing from the outer peripheral surface of the first section 411 to the outside of the cleaning base station or from the outer peripheral surface of the second section 413 to the outlet 312 of the filter chamber 31.

[0095] (4) The control method of the clean base station of this application can improve the service life of the clean base station to a certain extent, and can also improve the maintenance cycle of the clean base station and reduce the maintenance cost of the clean base station to a certain extent.

[0096] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
