Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and specifically to a cleaning base station. Background Technology

[0002] With the development of household cleaning equipment and the increasing demands of home users for cleaning results, cleaning equipment such as floor scrubbers and mopping robots are favored by consumers for their high efficiency, convenience, environmental friendliness, and ability to be used both wet and dry. These cleaning devices are typically equipped with a cleaning base station, which can automatically clean and maintain the equipment, such as automatically adding water, charging, self-cleaning, and wastewater discharge, further freeing up users' hands.

[0003] In existing technologies, the internal water pipe layout of cleaning base stations is complex, and these pipes are prone to bending and compression during production and transportation. Furthermore, for some cleaning base stations with heating functions, scale can easily clog the heating mechanism after prolonged use, leading to a significant increase in water pressure in the inlet pipe. This can cause water pipes to detach or burst during use. Water can leak from the bottom of the base station, soaking the floor or other items, resulting in a poor user experience.

[0036] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0040] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0041] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0042] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0043] This disclosure provides a cleaning base station, which is used in conjunction with cleaning equipment to perform cleaning work. The cleaning equipment is used to clean work surfaces such as floors and carpets. The cleaning equipment and the cleaning base station can be connected to each other so that the cleaning equipment can be maintained and cleaned on the cleaning base station. For example, the cleaning equipment can be charged, self-cleaned, drained, and rehydrated on the cleaning base station, thus automating the various cleaning processes.

[0044] The cleaning equipment can be handheld, such as handheld cleaning machines, handheld wet vacuum cleaners, handheld floor scrubbers, handheld fabric cleaners, and other handheld cleaning devices well-known to those skilled in the art; or it can be self-moving cleaning devices well-known to those skilled in the art, such as floor cleaning robots and sweeping and mopping robots. The cleaning equipment includes a main body, and components such as cleaning parts, a clean water tank, and a wastewater tank mounted on the main body. The main body serves as a carrier for installing various functional components required by the cleaning equipment. The cleaning parts are the main components used to clean the work surface; specifically, the cleaning parts can be structures such as roller brushes and mop pads that enable wet mopping.

[0045] The clean water tank holds the liquid used to clean the work surface. Specifically, the machine body can also be equipped with a spraying mechanism that sprays clean water or cleaning fluid from the clean water tank onto the work surface to be cleaned, or directly onto the work surface, thus ensuring cleaning effectiveness. The wastewater tank is used to temporarily store the dirt after cleaning. Specifically, the machine body can also be equipped with a suction port. While the cleaning equipment is moving and cleaning, the dirt after cleaning can be sucked into the wastewater tank through the suction port for storage, facilitating subsequent centralized treatment.

[0046] The clean base station provided in this disclosure includes a base station body and a water supply component disposed on the base station body. The base station body is the main structure of the clean base station, and a receiving cavity can be formed on the clean body. Cleaning equipment can enter the receiving cavity for docking, thereby realizing functions such as charging, sewage discharge, and self-cleaning. In one embodiment of this disclosure, a cleaning tank 31 is provided on the base station body. The cleaning tank 31 is configured for self-cleaning by the cleaning equipment. Specifically, the cleaning tank 31 can be formed at the bottom of the receiving cavity. When the cleaning equipment is docked, the cleaning component can be located in the cleaning tank 31 and perform a self-cleaning procedure within the cleaning tank 31.

[0047] The water supply component is a water circuit structure that supplies water to the cleaning equipment from the cleaning base station. Specifically, the water supply function can include: replenishing the clean water tank of the cleaning equipment, and supplying water to the cleaning tank 31 to enable the cleaning components to self-clean. (Reference) Figure 1 and Figure 2 The water supply assembly includes a heating mechanism 1, a pressure relief valve 2, and a pressure relief pipe 20. The heating mechanism 1 is configured to connect to a water source via a water inlet pipe 10 and is equipped to heat the liquid coming from the water inlet pipe 10. Specifically, during water supply, the heating of the liquid coming from the water inlet pipe 10 can be controlled by program settings. The liquid flowing through the heating mechanism 1 can flow to the cleaning equipment, thereby supplying water to the cleaning equipment.

[0048] In existing technologies, the water inlet pipe 10 is prone to bending and compression during production and transportation. Furthermore, the heating mechanism 1 is susceptible to scale buildup after prolonged operation, which can easily clog it. Since the water inlet pipe 10 is connected upstream of the heating mechanism 1, a blockage can cause a significant increase in water pressure within the pipe, potentially leading to pipe detachment or bursting during use. Water may leak from the bottom of the cleaning base station, soaking floors or items and resulting in a poor user experience.

[0049] To address the aforementioned issues, this disclosure includes a pressure relief valve 2 on the inlet pipe 10. Specifically, the pressure relief valve 2 is configured to switch between an open and a closed state: when the pressure within the inlet pipe 10 is less than or equal to a threshold, the pressure relief valve 2 remains closed; when the pressure within the inlet pipe 10 exceeds the threshold, the pressure relief valve 2 switches to the open state. The pressure relief pipe 20 is connected to the output end of the pressure relief valve 2. When the pressure relief valve 2 is open, a portion of the fluid in the inlet pipe 10 is directed to flow into the pressure relief pipe 20 via the pressure relief valve 2 and then be discharged via the pressure relief pipe 20.

[0050] In one specific embodiment of this disclosure, a three-way valve seat 7 is provided on the water inlet pipe 10, and a pressure relief valve 2 is installed on the three-way valve seat 7, as shown in the reference. Figure 4 The pressure relief valve 2 includes a first valve cover 21, an elastic element 22, a valve core 23, and a sealing ring 24. The first valve cover 21 is mounted on a three-way valve seat 7 and has an output end. The pressure relief pipe 20 can be sleeved onto the output end of the first valve cover 21, thereby communicating with the valve chamber of the pressure relief valve 2. The elastic element 22 can be pre-pressed between the first valve cover 21 and the valve core 23, and the sealing ring 24 can be disposed between the valve core 23 and the three-way valve seat 7. Under the elastic force of the elastic element 22 and the sealing effect of the sealing ring 24, the pressure relief valve 2 can remain closed while the water supply assembly is operating normally, allowing fluid to flow normally within the water inlet pipe 10 without entering the pressure relief pipe 20.

[0051] If the pressure inside the inlet pipe 10 becomes excessively high due to bending, compression, or scaling and blockage of the heating mechanism 1, exceeding the threshold, the pressure relief valve 2 switches to the open state. Under the pressure inside the inlet pipe 10, the valve core 23 moves and compresses the elastic element 22, allowing fluid from the inlet pipe 10 to flow into the valve chamber and be discharged through the pressure relief pipe 20, thereby quickly reducing the pressure inside the inlet pipe 10. It should be noted that when the heating mechanism 1 is operating, there may be a certain amount of steam in the inlet pipe 10 in addition to liquid water, which may also cause the pressure inside the inlet pipe 10 to rise. In this case, the fluid inside the inlet pipe 10 can be a gas-liquid mixture, which can be discharged through the pressure relief pipe 20, thereby reducing the pressure inside the inlet pipe 10. When the pressure inside the inlet pipe 10 drops to the threshold, the pressure is less than the elastic force generated by the compression of the elastic element 22, causing the valve core 23 to reset under the action of the elastic force. The pressure relief valve 2 switches to the closed state, and the water supply assembly can quickly return to normal after the pressure relief is completed, continuing the water supply operation.

[0052] This disclosure provides a pressure relief valve 2 on the water inlet pipe 10 and a pressure relief pipe 20 connected to the output end of the pressure relief valve 2. This allows the pressure relief valve 2 to open and release pressure when the pressure inside the water inlet pipe 10 exceeds a threshold. A portion of the fluid in the water inlet pipe 10 (which may be a gas-liquid mixture when the heating mechanism 1 is operating) can be discharged through the pressure relief pipe 20, thereby reducing the pressure inside the water inlet pipe 10 to below the threshold. At this point, the pressure relief valve 2 can be switched back to the closed state, allowing the cleaning base station to resume normal operation. This disclosure effectively prevents the water pipe from detaching or bursting due to excessive pressure inside the water inlet pipe 10, avoiding water leakage from the cleaning base station and improving the user experience.

[0053] In one embodiment of this disclosure, reference is made to Figure 5 and Figure 6 The water supply assembly includes a first outlet pipe 11 connecting the heating mechanism 1 to the cleaning tank 31. The liquid heated by the heating mechanism 1 is configured to be transported to the cleaning tank 31 through the first outlet pipe 11. Specifically, when the cleaning equipment needs to perform self-cleaning, the heating mechanism 1 can be controlled to operate, thereby controlling the water supply assembly to supply hot water to the cleaning tank 31. The liquid in the inlet pipe 10 flows into the heating mechanism 1, and the heated hot water can flow into the cleaning tank 31 through the first outlet pipe 11, thereby realizing the cleaning and disinfection of the cleaning parts using hot water. Using hot water for self-cleaning can accelerate the dissolution of oil stains, soften stains, enhance the activity of cleaning agents, enhance the bactericidal and bacteriostatic effects, and avoid odors. Compared with using room temperature water for self-cleaning, this disclosure heats the liquid transported to the cleaning tank 31, thereby improving the self-cleaning effect of the cleaning equipment.

[0054] In one embodiment of this disclosure, reference continues to be made to... Figure 5 and Figure 6 The base station body is equipped with a water replenishment connector 32 for connecting to the clean water tank. When the cleaning equipment is in place, the water replenishment connector 32 can connect with the water inlet on the clean water tank, thereby enabling the cleaning base station to replenish the clean water tank of the cleaning equipment through the water supply component. The water supply component includes a second water outlet pipe 12 connecting the heating mechanism 1 to the water replenishment connector 32. When water replenishment is needed, the heating mechanism 1 can be selectively controlled to operate according to the upcoming cleaning operation, thereby adjusting the temperature of the water replenished into the clean water tank.

[0055] For example, when the cleaning equipment needs to clean the kitchen area, since kitchens often have stubborn stains and grease, hot water is needed for mopping to accelerate the dissolution of grease, soften stains, enhance the activity of cleaning agents, and improve the sterilization and antibacterial effects. At this time, the heating mechanism 1 can be controlled to operate, thereby controlling the water supply component to deliver hot water to the clean water tank through the water inlet connector 32. The liquid in the water inlet pipe 10 flows into the heating mechanism 1, and the heated liquid is configured to be delivered to the water inlet connector 32 through the second water outlet pipe 12, thus enabling the cleaning equipment to use hot water for subsequent cleaning work.

[0056] In other cleaning scenarios, such as when cleaning wooden floors, hot water is not recommended as it may accelerate warping, cracking, or aging of the surface coating. Using room temperature water is safer. Alternatively, for light stains or frequent cleaning, hot water may not be necessary to achieve the desired cleaning effect, thus reducing energy consumption. In these scenarios, at least during water replenishment, the heating mechanism 1 is configured to remain closed to deliver room temperature liquid to the water replenishment connector 32 via the second outlet pipe 12. Liquid in the inlet pipe 10 flows into the heating mechanism 1, which remains closed, maintaining the liquid at room temperature. The liquid then flows from the second outlet pipe 12 to the water replenishment connector 32, allowing the cleaning equipment to use room temperature water for subsequent cleaning operations.

[0057] In one specific embodiment of this disclosure, a main water outlet pipe 13 is connected downstream of the heating mechanism 1, and a first water outlet pipe 11 and a second water outlet pipe 12, which are connected in parallel downstream of the main water outlet pipe 13, are connected downstream of the main water outlet pipe 13. The first water outlet pipe 11 is equipped with a first on / off valve 111, and the second water outlet pipe 12 is equipped with a second on / off valve 121. As mentioned above, the first water outlet pipe 11 is connected to the cleaning tank 31, and the second water outlet pipe 12 is connected to the water supply connector 32. When hot water needs to be supplied to the cleaning tank 31, the first on / off valve 111 can be opened, and the second on / off valve 121 can be kept closed, thereby opening the water path between the heating mechanism 1 and the cleaning tank 31. When hot water or room temperature water needs to be supplied to the water supply connector 32, the second on / off valve 121 can be opened, and the first on / off valve 111 can be kept closed, thereby opening the water path between the heating mechanism 1 and the water supply connector 32.

[0058] In one embodiment of this disclosure, a sewage trough 33 is provided on the base station body. Specifically, the sewage trough 33 is used to collect dirt and grime. The sewage trough 33 can be connected to a sewer, so that the dirt and grime in the sewage trough 33 can be discharged externally. The wastewater tank of the cleaning equipment can be connected to the sewage trough 33, thereby discharging the dirt and grime collected during the cleaning process into the sewage trough 33. The sewage trough 33 can also be connected to the cleaning tank 31, so that the dirt and grime generated after self-cleaning in the cleaning tank 31 can also be discharged into the sewage trough 33. The pressure relief pipe 20 is configured to connect to the sewage trough 33, thereby allowing the fluid discharged from the pressure relief pipe 20 to be discharged externally through the sewage trough 33 without the need to set up a dedicated drain outlet for the pressure relief pipe 20, reducing the structural complexity of the cleaning base station and optimizing the internal water circuit structure of the cleaning base station.

[0059] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 6 The base station body is equipped with a water storage tank 4, and the water supply component includes a water pump 51. The water inlet pipe 10 is configured to connect the water pump 51 to the water storage tank 4, and the pressure relief valve 2 is located downstream of the water pump 51. The water pump 51 is configured to pump the liquid in the water storage tank 4 to the heating mechanism 1. In this embodiment, the clean base station is equipped with a water storage tank 4. When the water supply component performs water supply work, the water pump 51 can pump the liquid in the water storage tank 4 out and deliver it to the heating mechanism 1 through the water inlet pipe 10. The pressure relief valve 2 is located downstream of the water pump 51. If the pressure in the water inlet pipe 10 is too high, the fluid in the part of the water inlet pipe 10 downstream of the water pump 51 can be discharged through the pressure relief pipe 20, thereby preventing the water pipe from falling off or bursting.

[0060] Furthermore, such as Figure 1 As shown, an overflow port 41 is provided at the upper part of the water storage tank 4, and an overflow pipe 42 is connected to the overflow port 41. Liquid above the overflow port 41 is discharged through the overflow pipe 42. It should be noted that, in this application, "above the overflow port 41" means that the amount of water added to the water storage tank 4 exceeds the lowest position of the overflow port 41. Specifically, users can add water to the water storage tank 4 themselves, or they can add water to the water storage tank 4 through other water supply structures. The water storage tank 4 has its maximum capacity. When the amount of water added is too large, in order to prevent liquid from leaking into other structures inside the cleaning base station, an overflow port 41 needs to be provided at the upper part of the water storage tank 4. Excess liquid can be discharged through the overflow port 41 and the overflow pipe 42, thereby controlling the water level in the water storage tank 4 to maintain at a predetermined height.

[0061] The pressure relief pipe 20 is configured to connect to the overflow pipe 42, and the fluid in the pressure relief pipe 20 is configured to be discharged through the overflow pipe 42. In this embodiment, the pressure relief pipe 20 utilizes part of the external drainage path of the overflow pipe 42. Specifically, when the pressure in the water inlet pipe 10 is too high, the pressure relief valve 2 opens, and the fluid flows in the pressure relief pipe 20 to the overflow pipe 42 and is discharged through the overflow pipe 42. The fluid discharged from the pressure relief pipe 20 can be discharged through the overflow pipe 42, thus eliminating the need to set up a dedicated drain outlet for the pressure relief pipe 20, reducing the structural complexity of the cleaning base station, and optimizing the internal water circuit structure of the cleaning base station.

[0062] In one embodiment of this disclosure, such as Figure 6 As shown, the overflow pipe 42 is configured to connect to the sewage tank 33, and the fluid in the pressure relief pipe 20 is configured to flow to the sewage tank 33 via the overflow pipe 42. The overflow pipe 42 is configured to connect to the sewage tank 33, thereby allowing the fluid discharged from both the overflow pipe 42 and the pressure relief pipe 20 to be discharged through the sewage tank 33 without the need for additional dedicated drain outlets for the overflow pipe 42 and the pressure relief pipe 20. This reduces the structural complexity of the cleaning base station and optimizes the internal water system structure of the cleaning base station.

[0063] In another embodiment of this disclosure, such as Figure 5 As shown, the cleaning base station may not require a water storage tank 4; instead, it can be directly connected to an external water source, such as a water pipe or faucet. In this embodiment, the water supply component includes a pressure regulating valve 52, and the inlet pipe 10 is configured to connect to an external water source through the pressure regulating valve 52. It is understood that the incoming water pressure from the external water source is usually unstable; therefore, a pressure regulating valve 52 is needed to maintain the incoming water pressure in the inlet pipe 10. Even when the flow rate of the external water source changes, the pressure regulating valve 52 can still maintain stable pressure, ensuring the normal operation of downstream equipment. The pressure relief valve 2 is located downstream of the pressure regulating valve 52. In the event of excessive pressure in the inlet pipe 10, the fluid in the portion of the inlet pipe 10 downstream of the pressure regulating valve 52 can be discharged through the pressure relief pipe 20, thereby preventing the water pipe from detaching or bursting.

[0064] In one embodiment of this disclosure, reference is made to Figure 1 The water supply assembly also includes a check valve 6, which is located upstream of the pressure relief valve 2 on the inlet pipe 10 and is configured to ensure that the fluid in the inlet pipe 10 flows only towards the heating mechanism 1. The check valve 6 remains normally open, preventing liquid in the inlet pipe 10 from flowing backwards through it. Fluid in the inlet pipe 10 can only accumulate downstream of the check valve 6 and cannot flow back upstream, thus preventing the water pump 51 or pressure regulating valve 52 from malfunctioning due to backflow. When the pressure downstream of the check valve 6 becomes too high, the pressure relief valve 2 automatically opens, thereby reducing the pressure in the inlet pipe 10.

[0065] In one specific embodiment of this disclosure, reference is made to Figure 3 and Figure 4 A three-way valve seat 7 is provided between the pressure relief valve 2 and the check valve 6. The three-way valve seat 7 includes an inlet 70, a first outlet 71, and a second outlet 72. The check valve 6 is installed at the inlet 70, the pressure relief valve 2 is installed at the first outlet 71, and the second outlet 72 is connected to the water inlet pipe 10. Figure 4 As shown, the check valve 6 specifically includes a duckbill valve 61 and a second valve cover 62. The liquid inlet of the check valve 6 is provided on the second valve cover 62. Liquid from upstream of the water inlet pipe 10 can flow into the check valve 6 through this end. Under the guiding action of the duckbill valve 61, the liquid can flow unidirectionally in the valve chamber of the water inlet pipe 10 and the three-way valve seat 7.

[0066] Furthermore, the second outlet 72 is configured to be coaxially arranged with the inlet 70. Under normal operating conditions, the pressure relief valve 2 remains closed, meaning the first outlet 71 remains closed, allowing the liquid flowing in from the inlet 70 to flow in a straight line to the second outlet 72. The first outlet 71 can extend in a direction perpendicular to the axis of the second outlet 72 and the inlet 70, thereby enabling the pressure relief valve 2 to more sensitively detect the pressure inside the three-way valve seat 7 and open it promptly when the pressure exceeds a threshold, preventing pipe rupture.

[0067] This disclosure also provides a clean water base station, including a heating mechanism 1, a pressure relief valve 2, a pressure relief pipe 20, and a water storage tank 4. The heating mechanism 1 is connected to a water source via a water inlet pipe 10 and can heat the liquid from the water inlet pipe 10. The pressure relief valve 2 is installed on the water inlet pipe 10 and switches between an open and closed state. When the pressure in the water inlet pipe 10 is less than or equal to a threshold, the pressure relief valve 2 remains closed; when the pressure in the water inlet pipe 10 is greater than the threshold, the pressure relief valve 2 switches to an open state. The pressure relief pipe 20 is connected to the output end of the pressure relief valve 2. When the pressure relief valve 2 is open, the liquid flowing through the pressure relief valve 2 flows into the pressure relief pipe 20 and is discharged through the pressure relief pipe 20. The water storage tank 4 has an overflow port 41, and an overflow pipe 42 is connected to the overflow port 41. Liquid above the overflow port 41 is discharged through the overflow pipe 42, and the overflow pipe 42 is connected to the pressure relief pipe 20.

[0068] During water supply to the cleaning base station, the liquid in the water storage tank 4 can be pumped out and delivered to the heating mechanism 1 through the water inlet pipe 10. When the pressure in the water inlet pipe 10 rises above a threshold, the pressure relief valve 2 is opened to release pressure. Part of the fluid in the water inlet pipe 10 (which may be a gas-liquid mixture when the heating mechanism is operating) can be discharged through the pressure relief pipe 20, thereby reducing the pressure in the water inlet pipe 10 to below the threshold. At this point, the pressure relief valve 2 can be switched back to the closed state, allowing the cleaning base station to resume normal operation. This disclosure effectively prevents water pipe detachment or bursting caused by excessive pressure in the water inlet pipe 10, avoiding water leakage from the cleaning base station and improving the user experience.

[0069] Furthermore, the overflow pipe 42 is connected to the pressure relief pipe 20, allowing the pressure relief pipe 20 to utilize part of the external drainage path of the overflow pipe 42. Specifically, when the pressure in the inlet pipe 10 is too high, the pressure relief valve 2 opens, and the fluid flows through the pressure relief pipe 20 to the overflow pipe 42 and is discharged through the overflow pipe 42. The fluid discharged from the pressure relief pipe 20 can be discharged through the overflow pipe 42, thus eliminating the need for a dedicated drainage outlet for the pressure relief pipe 20, reducing the structural complexity of the cleaning base station, and optimizing the internal water circuit structure of the cleaning base station.

[0070] Application scenarios

[0071] In home cleaning scenarios, the cleaning equipment is a mopping robot. After completing the cleaning task, the mopping robot returns to the cleaning base station for self-cleaning and water replenishment. Specifically, the mopping robot needs to clean the kitchen area next. In order to improve the oil removal effect, hot water needs to be added to the clean water tank.

[0072] During the self-cleaning process, the heating mechanism 1 is activated, thereby controlling the water supply assembly to deliver hot water to the cleaning tank 31. Specifically, the water pump 51 pumps liquid from the water storage tank 4 into the inlet pipe 10, and the liquid in the inlet pipe 10 flows into the heating mechanism 1. The heated hot water flows through the first outlet pipe 11 into the cleaning tank 31, thus achieving the cleaning and disinfection of the cleaning components using hot water. Using hot water for self-cleaning can accelerate the dissolution of oil stains, soften dirt, enhance the activity of cleaning agents, improve the bactericidal and bacteriostatic effects, and prevent odors.

[0073] During the water replenishment process, the heating mechanism 1 is activated, thereby controlling the water supply component to deliver hot water to the clean water tank through the water replenishment connector 32. Specifically, the water pump 51 pumps the liquid in the water storage tank 4 into the water inlet pipe 10, and the liquid in the water inlet pipe 10 flows into the heating mechanism 1. The liquid heated by the heating mechanism 1 is then configured to be delivered to the water replenishment connector 32 through the second water outlet pipe 12, thereby enabling the mopping robot to use hot water for subsequent cleaning work.

[0074] After a period of use, the heating mechanism 1 of the cleaning base station develops scale buildup and blockage. Therefore, during a water filling process, the water pressure in the inlet pipe 10 rises above the threshold. The pressure relief valve 2 opens, allowing some fluid in the inlet pipe 10 (which may be a gas-liquid mixture when the heating mechanism 1 is operating) to be discharged through the pressure relief pipe 20, thus reducing the pressure in the inlet pipe 10 below the threshold. At this point, the pressure relief valve 2 can switch back to the closed state, allowing the cleaning base station to resume normal operation. This disclosure effectively prevents water pipe detachment or bursting caused by excessive pressure in the inlet pipe 10, avoiding water leakage from the cleaning base station and improving the user experience.
