Technical Field
[0001] This application relates to the technical field of cleaning equipment, and more specifically, to a base station and a cleaning system. Background Technology
[0002] After completing their cleaning tasks, automated robotic vacuum cleaners will perform self-cleaning or recharge at the base station. Therefore, the base station is crucial for the logistical support of automated robotic vacuum cleaners.
[0003] To provide a stable flow rate and ensure water system stability for existing sweeping robot water supply and drainage base stations, a clean water tank needs to be added before the pump as a buffer. The presence of the clean water tank also necessitates the matching of dozens of components, including electromagnetic pressure reducing valves, float switches, float switches, and overflow pipes. The overall size of the base station is relatively large due to the presence of the water tank and these components, affecting the layout of other structures within the base station. Utility Model Content
[0004] The purpose of this application is to address the technical problems in related technologies by providing a base station and a cleaning system. The specific solution is as follows:
[0005] This application provides a base station, including:
[0006] The base station itself includes an inlet and an outlet.
[0007] The water supply assembly includes a negative pressure valve and a water pump. One end of the negative pressure valve is connected to an external water source, and the other end is connected to one end of the water pump. The other end of the water pump is connected to the water inlet.
[0008] In response to the water pump being turned on, the negative pressure valve opens, and the external water source supplies water to the base station through the negative pressure valve, the water pump, the inlet, and the outlet; in response to the water pump being turned off, the negative pressure valve closes, and the external water source stops supplying water to the base station.
[0009] In some embodiments, a two-position three-way valve is also included, disposed between the negative pressure valve and the water pump.
[0010] In some embodiments, the two-position three-way valve includes a first interface, a second interface, and a third interface. The first interface is connected to the negative pressure valve, the second interface is connected to the water pump, and the third interface is directed to the sewage discharge area. When the negative pressure valve is open, the first interface and the second interface are connected, and when the negative pressure valve is closed, the first interface and the third interface are connected.
[0011] In some embodiments, a solenoid valve is also included, disposed between the external water source and the negative pressure valve.
[0012] In some embodiments, a two-position three-way valve is also included, disposed between the negative pressure valve and the water pump or between the solenoid valve and the negative pressure valve.

[0017] This application also provides a cleaning system, including cleaning equipment and a base station as described above, wherein the base station replenishes water to the cleaning equipment and / or replenishes water to the cleaning tank of the base station through the water outlet.
[0018] Compared with the prior art, this application has at least the following technical effects:
[0019] This application proposes a base station and a cleaning system. The base station utilizes a negative pressure valve and a water pump to automatically supply water from an external source. When the water pump is turned on, the negative pressure valve opens under negative pressure, allowing external water to automatically supply water to the cleaning tank and / or the water tank of the cleaning equipment through the negative pressure valve, the water pump, and the base station's water inlet. When the water pump is turned off, the negative pressure valve closes, and the external water supply to the base station ceases. The entire water supply structure eliminates the need for a clean water tank and associated accessories, reducing base station costs and space requirements.

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, and other quantifiers are similar.
[0032] It should be understood that although the terms "first," "second," "third," etc., may be used in the embodiments of this application, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of the embodiments of this application. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0033] It should be understood that the term "and / or" used in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The singular forms "a" and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.
[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or device that includes that element.
[0036] In related technologies, base stations are equipped with a clean water tank that stores clean water. The tank includes components such as an electromagnetic pressure reducing valve, a float switch, a float switch, and an overflow pipe. When the cleaning equipment returns to the base station, the control system controls the clean water tank to supply water to the cleaning equipment. When the water level in the tank drops to a preset threshold, the control system controls an external water source to supply water to the tank, ensuring it has water for subsequent use. Therefore, the clean water tank assembly occupies a significant amount of space in the base station, increasing its manufacturing cost.
[0037] Therefore, this application provides a base station, including: a base station body, including a water inlet and a water outlet; a water supply assembly, including a negative pressure valve and a water pump, wherein one end of the negative pressure valve is connected to an external water source, and the other end is connected to one end of the water pump, and the other end of the water pump is connected to the water inlet; wherein, in response to the water pump being turned on, the negative pressure valve is opened, and the external water source supplies water to the base station through the negative pressure valve, the water pump, the water inlet, and the water outlet; in response to the water pump being turned off, the negative pressure valve is closed, and the external water source stops supplying water to the base station.
[0038] The base station proposed in this application uses a negative pressure valve and a water pump to achieve automatic water supply from an external source. When the water pump is turned on, the negative pressure valve opens under negative pressure, and the external water source automatically supplies water to the base station through the negative pressure valve, the water pump, and the base station's water inlet. When the water pump is turned off, the negative pressure valve closes, and the external water source stops supplying water to the base station. The entire water supply structure does not require a clean water tank or related accessories, which can reduce the cost of the base station and reduce the space required for the base station.
[0039] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.
[0040] like Figure 1 As shown, this application embodiment provides a base station 100, which includes a base station body 120. The base station body 120 includes a water inlet 121 and a water outlet 122. The water inlet 121 and the water outlet 122 can be directly connected or connected through a control unit. The water outlet is used to supply water to the water tank of the cleaning device 300 or to provide self-cleaning water to the cleaning device 300. The base station 100 also includes a water supply component 110, which includes a negative pressure valve 111 and a water pump 112. One end of the negative pressure valve 111 is connected to an external water source 200, and the other end is connected to one end of the water pump 112. The other end of the water pump 112 is connected to an inlet 121. In response to the opening of the water pump 112, the negative pressure valve 111 opens under the action of negative pressure, and the external water source 200 supplies water to the base station 100 through the negative pressure valve 111, the water pump 112, the inlet 121, and the outlet 122. In response to the closing of the water pump 112, the negative pressure valve 111 closes, and the external water source 200 stops supplying water to the base station 100.
[0041] As can be seen, the base station 100 of this application can achieve automatic water supply from an external water source by using the cooperation of a negative pressure valve 111 and a water pump 112. When the water pump 112 is turned on, the negative pressure valve 111 opens under the action of negative pressure, and the external water source 200 flows into the base station body 120 through the negative pressure valve 111 and the water pump 112. According to the water supply needs, water can be supplied directly to the base station through the base station water inlet 121 or to replenish the water tank of the cleaning equipment. When the water pump 112 is turned off, the negative pressure valve 111 closes, and the external water source 200 stops supplying water to the base station. Except for the water supply component 110, there is no need to set up a clean water tank and an accessory water storage structure, which can greatly reduce the structural components of the base station body, reduce the base station space, increase the design space for other components, and reduce the cost of the base station.
[0042] It should be noted that this application describes further improvements to different embodiments through multiple embodiments. The same structures between the multiple embodiments will not be repeated, only the different structural components or functions will be described. Therefore, the multiple embodiments of this application can be implemented in parallel or separately or in arbitrary combinations, which should be reasonably understood.
[0043] In some embodiments, such as Figure 2As shown, the water supply assembly 110 also includes a two-position three-way valve 113, which is located between the negative pressure valve 111 and the water pump 112. The two-position three-way valve 113 plays a protective role in the water supply assembly 110. When the negative pressure valve 111 fails due to foreign objects or other reasons and leaks water, the leaked water flows from the normally open circuit of the two-position three-way valve 113 into the sewage area, avoiding damage to the base station.
[0044] Specifically, such as Figure 3 and Figure 4 As shown, the two-position three-way valve 113 includes a first port 1131, a second port 1132, and a third port 1133. The first port 1131 is connected to the negative pressure valve 111, the second port 1132 is connected to the water pump 112, and the third port 1133 is directed to the sewage discharge area. When the negative pressure valve 111 is open, the first port 1131 and the second port 1132 are connected, and the water supply component 110 supplies water normally. When the negative pressure valve 111 is closed, the first port 1131 and the second port 1132 are closed, and the first port 1131 and the third port 1133 are connected. When the negative pressure valve 111 fails due to foreign objects or other reasons and leaks water, the leaked water flows from the first port 1131 of the two-position three-way valve 113 into the sewage discharge area through the third port 1133, avoiding damage to the base station.
[0045] In some embodiments, such as Figure 5 As shown, the water supply assembly 110 also includes a solenoid valve 114, which is located between the external water source 200 and the negative pressure valve 111. When water supply is needed, the external controller controls the water pump 112 to open. At this time, the negative pressure valve 111 also opens due to the negative pressure. Then, the solenoid valve 114 is opened to conduct the water circuit. Due to the addition of multiple water supply switches in the water supply assembly 110, the safety of the water circuit is ensured.
[0046] In some embodiments, such as Figure 5 As shown, the water supply assembly 110 also includes a solenoid valve 114 and a two-position three-way valve 113. The two-position three-way valve 113 is located between the negative pressure valve 111 and the water pump 112, or between the solenoid valve 114 and the negative pressure valve 111, and can be flexibly configured as needed. The opening and function of the two-position three-way valve 113 are described in the above embodiment and will not be repeated here. In this embodiment, the water supply assembly 110 enhances the safety of the water supply assembly by setting the solenoid valve 114 and the two-position three-way valve 113. During non-water supply, the water pump 112 is turned off. When the negative pressure valve 111 is damaged, the seepage water is guided to the drainage area through the two-position three-way valve 113. Of course, when the negative pressure valve 111 is damaged, the solenoid valve 114 can also be kept closed to further prevent the seepage water from damaging the base station.
[0047] In some embodiments, the base station further includes a controller connected to the solenoid valve 114 and the water pump 112, the controller being used to control the opening and closing of the solenoid valve 114 and the water pump 112.
[0048] In some embodiments, the base station further includes a cleaning agent component configured to provide cleaning agent to the base station. Depending on the base station's need to clean the cleaning equipment, cleaning agent can be provided at appropriate locations through the cleaning agent component during water supply from the water supply component to enhance the base station's decontamination capabilities.
[0049] In some embodiments, the base station further includes a filter component disposed at any location between the external water source 200 and the water inlet 121, optionally disposed at the first location where water flows into the water supply component 110, in order to protect all components in the water supply component 110.
[0050] In some embodiments, the base station further includes a heating component disposed between the water inlet 121 and the water outlet 122. After the water flows into the base station body 120 through the water inlet 121, the heating component can be installed to heat the water before it flows out of the base station body 120, so as to further enhance the decontamination ability.
[0051] This application also provides a cleaning system, including a cleaning device 300 and a base station 100 as described above. The base station 100 supplies water to the cleaning device 300 through a water outlet 122, enabling the cleaning device to mop the floor. The base station 100 can also supply water to a base station cleaning tank through the water outlet 122 to enable the cleaning device 300 to self-clean, thereby cleaning the mop cloth of the cleaning device 300. Related structures are described in reference to existing technologies and will not be elaborated upon here.
[0052] This application proposes a base station and a cleaning system. The base station utilizes a negative pressure valve and a water pump to automatically supply water from an external source. When the water pump is turned on, the negative pressure valve opens under negative pressure, allowing external water to automatically supply water to the base station or to the cleaning equipment's water tank through the negative pressure valve, the water pump, and the base station's inlet. When the water pump is turned off, the negative pressure valve closes, and the external water supply to the base station ceases. The entire water supply structure eliminates the need for a clean water tank and associated accessories, reducing base station costs and space requirements.
[0053] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.
[0054] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
