[0033] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0034] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0035] Although the terms second, first, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "second," "first," and other numerical terms used herein do not imply order or sequence. Therefore, the second element, component, region, layer, or segment discussed below may be referred to as the first element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure.

For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] Figure 1 This is a three-dimensional structural diagram of a liquid storage tank according to an embodiment of this application. Figure 2 for Figure 1 The diagram shows the structure of the liquid storage tank with the connector assembly in a disassembled state. Figure 3 for Figure 2 The diagram shows a cross-sectional view of the connector assembly in the liquid storage tank in a separated state.

[0038] See Figures 1 to 3 This application provides a liquid storage tank 100, including: a connector assembly 1 and a tank body 2.

[0039] The connector assembly 1 includes a detachably connected first connector 11 and a second connector 12. The first connector 11 is used to connect to the housing 2, and the second connector 12 is used to connect to the water passage. The first connector 11 is provided with a first channel and a first valve core 111 movably connected to the first channel. The second connector 12 is provided with a second channel and a second valve core 121 movably connected to the second channel.

[0040] When the first connector 11 is connected to the second connector 12, the first valve core 111 opens the first channel and the second valve core 121 opens the second channel so that the first channel and the second channel are connected; when the first connector 11 is separated from the second connector 12, the first valve core 111 closes the first channel and the second valve core 121 closes the second channel.

[0041] In this embodiment, the liquid storage tank 100 can be applied to a cleaning base station to provide cleaning water for cleaning equipment such as sweeping robots and sweeping and mopping machines. The liquid storage tank 100 includes a tank body 2 and a connector assembly 1. The first connector 11 of the connector assembly 1 is connected to the tank body 2. The first valve core 111 inside the first connector 11 is movably connected to the first channel, which is used to communicate with the tank body 2. The second connector 12 is detachably connected to the first connector 11. The second valve core 121 inside the second connector 12 is movably connected to the second channel, which is used to communicate with a water passage. The water passage can be set on the cleaning base station and connected to the second connector 12 through a pipeline.

[0042] When the clean water in the storage tank 100 is insufficient, the first connector 11 and the second connector 12 need to be connected. At this time, the first valve core 111 opens the first channel, and the second valve core 121 opens the second channel, so that the first channel and the second channel are connected, that is, the tank 2 is connected to the water circuit, thus meeting the functional requirements. When the clean water in the storage tank 100 is full, the first connector 11 and the second connector 12 need to be separated. At this time, the first valve core 111 closes the first channel, and the second valve core 121 closes the second channel, thereby achieving a double seal between the storage tank 100 and the water circuit when disassembled, preventing residual liquid in the storage tank 100 and the water circuit from flowing out, and improving the reliability of the product.

[0043] According to an embodiment of this application, the connector assembly 1 is applied between the housing 2 and the water channel. The connector assembly 1 includes a detachably connected first connector 11 and a second connector 12. The first connector 11 is used to connect to the housing 2, and the second connector 12 is used to connect to the water channel. The first connector 11 is provided with a first channel and a first valve core 111 movably connected to the first channel. The second connector 12 is provided with a second channel and a second valve core 121 movably connected to the second channel. When the first connector 11 and the second connector 12 are connected, the first valve core 111 opens the first channel, and the second valve core 121 opens the second channel, so that the first channel and the second channel are connected, that is, the housing 2 is connected to the water channel, which meets the working requirements. When the first connector 11 and the second connector 12 are separated, the first valve core 111 closes the first channel, and the second valve core 121 closes the second channel, which can prevent leakage from the water channel or the housing 2. When the connector assembly 1 is applied to the liquid storage tank 100 of the cleaning base station, the possibility of short circuit in the cleaning base station can be reduced, and the reliability is high.

[0044] Figure 4 for Figure 2 The diagram shows a cross-sectional view of the connector assembly in the liquid storage tank in the connected state. Figure 5 for Figure 2 A schematic cross-sectional view of the first connector in the connector assembly shown.

[0045] In some embodiments, the first connector 11 further includes a first mounting base 113 and a first sealing member 114. The housing 2 has an opening 21 and a flange 22 disposed around the periphery of the opening 21. The first mounting base 113 covers the flange 22 to form a first channel. The first sealing member 114 is disposed between the outer periphery of the first valve core 111 and the inner wall of the first channel. The second connector 12 further includes a second mounting base 123 and a second sealing member 124. The second mounting base 123 is provided with a second channel. The second sealing member 124 is disposed between the outer periphery of the second valve core 121 and the inner wall of the second channel. When the first connector 11 and the second connector 12 are connected, the first valve core 111 and the second valve core 121 abut against each other to open the first channel and the second channel respectively.

[0046] See Figures 3 to 5 The first mounting base 113 is connected to the housing 2 by fasteners. A first sealing element 114 is disposed between the outer periphery of the first valve core 111 and the inner wall of the first channel, and a second sealing element 124 is disposed between the outer periphery of the second valve core 121 and the inner wall of the second channel. Optionally, both the first sealing element 114 and the second sealing element 124 are silicone gaskets. When the first connector 11 is connected to the second connector 12, the first valve core 111 and the second valve core 121 abut against each other to open the first channel and the second channel respectively. The first seal 114 and the second seal 124 both fail, allowing the first channel and the second channel to communicate and meet the working requirements. When the first connector 11 is separated from the second connector 12, the first valve core 111 closes the first channel, and the first seal 114 seals between the outer peripheral side of the first valve core 111 and the inner wall of the first channel, which can prevent the housing 2 from leaking liquid. The second valve core 121 closes the second channel, and the second seal 124 seals between the outer peripheral side of the second valve core 121 and the inner wall of the second channel, which can prevent the water circuit from leaking liquid.

[0047] In some embodiments, a first receiving cavity 1121 is formed on the side of the bottom wall 1130 of the first mounting base 113 facing the housing 2, and a hollow shaft 1122 is provided on the side of the bottom wall 1130 of the first mounting base 113 away from the housing 2. The first receiving cavity 1121 surrounds the outer periphery of the flange 22 and communicates with the inner cavity of the hollow shaft 1122 to form a first channel. The first valve core 111 includes a first head 1111 and a first rod portion 1112 connected to the first head 1111. The first head 1111 is located inside the flange 22, and a first elastic member 115 is provided between the first head 1111 and the opening 21 of the housing 2. The first rod portion 1112 is telescopically disposed between the flange 22 and the hollow shaft 1122 through the first elastic member 115. The first sealing member 114 is sleeved on the outer periphery of the first rod portion 1112 and is located between the flange 22 and the bottom wall 1130.

[0048] See again Figure 5The bottom wall 1130 of the first mounting base 113 of the first connector 11 has a first accommodating cavity 1121 and a hollow shaft 1122 that are interconnected on both sides. The first accommodating cavity 1121 surrounds the outer periphery of the flange 22 of the housing 2 and communicates with the inner cavity of the hollow shaft 1122 to form a first channel. The first valve core 111 in the first connector 11 is movably connected to the first channel by a first elastic element 115. Optionally, the first elastic element 115 is a compressible spring. In its natural state, the first elastic element 115 is pre-compressed a certain distance and is located in the flange 22, between the opening 21 of the housing 2 and the first head 1111 of the first valve core 111, so that the first sealing element 114 can seal the first channel under the pre-pressure of the first elastic element 115, thereby sealing the housing 2.

[0049] See again Figure 4 When the first connector 11 is connected to the second connector 12, the first valve core 111 and the second valve core 121 abut against each other. The second valve core 121 can push the first valve core 111 to move along the bottom wall 1130 away from the first mounting seat 113, forcing the first elastic member 115 to deform and compress, making the gap between the first head 1111 and the bottom wall 1130 larger, the first valve core 111 and the first seal 114 separate, the first seal 114 fails, and the first channel opens to form a passage.

[0050] In addition, when the first connector 11 and the second connector 12 are separated, the first seal 114 can seal the first channel under the pre-pressure of the first elastic member 115. Outside air can be pumped in the opposite direction from the outlet of the first channel (i.e. the end of the hollow shaft 1122 away from the first accommodating cavity 1121) to form positive pressure and prevent water backflow.

[0051] Figure 6 for Figure 2 The diagram shows a three-dimensional structure of the second connector in the connector assembly. Figure 7 for Figure 6 Cross-sectional view along direction BB.

[0052] In some embodiments, the second mounting base 123 includes a second accommodating cavity 1221 and a third accommodating cavity 1222 forming a second channel. The second connector 12 also includes a water pipe connector 125 communicating with a water passage. One end of the water pipe connector 125 away from the water passage is embedded in the third accommodating cavity 1222. A partition 1223 is provided between the second accommodating cavity 1221 and the third accommodating cavity 1222. The second valve core 121 includes a second head 1211 and a second rod portion 1212 connected to the second head 1211. The second rod portion 1212 penetrates the partition 1223. A second elastic element 126 is provided between the second head 1211 and the water pipe connector 125. The second rod portion 1212 is telescopically disposed between the third accommodating cavity 1222 and the second accommodating cavity 1221 through the second elastic element 126. The second sealing element 124 is sleeved on the outer periphery of the second rod portion 1212 and is located between the second head 1211 and the partition 1223.

[0053] See Figure 3 , 6 and Figure 7 The second mounting base 123 of the second connector 12 includes a second receiving cavity 1221 and a third receiving cavity 1222 forming a second channel. One end of the water pipe connector 125 is a connector connected to a water pipe, and the other end of the water pipe connector 125 is embedded in the third receiving cavity 1222, so that a second channel is formed between the second receiving cavity 1221, the third receiving cavity 1222 and the water pipe connector 125.

[0054] Optionally, the water pipe connector 125 and the second mounting base 123 are connected by a snap-fit ​​connection. For example... Figure 6 As shown, the outer periphery of the water pipe connector 125 is provided with two first snap-fit ​​parts 1251 at intervals, and the outer wall of the second mounting base 123 is provided with two corresponding second snap-fit ​​parts 1231. The first snap-fit ​​parts 1251 and the second snap-fit ​​parts 1231 are connected by snap-fit.

[0055] Furthermore, the second accommodating cavity 1221 and the third accommodating cavity 1222 are separated by a partition 1223, and a second elastic element 126 is provided between the second head 1211 of the second valve core 121 and the water pipe connector 125. The second valve core 121 in the second connector 12 is movably connected to the second channel through the second elastic element 126. Optionally, the second elastic element 126 is a compressible spring. In its natural state, the second elastic element 126 is pre-compressed a certain distance and disposed in the third accommodating cavity 1222, and is located between the water pipe connector 125 and the second head 1211 of the second valve core 121, so that the second sealing element 124 can seal the second channel under the pre-pressure of the second elastic element 126, thereby achieving a water circuit seal.

[0056] See again Figure 4When the first connector 11 is connected to the second connector 12, the first valve core 111 and the second valve core 121 abut against each other. The first valve core 111 can push the second valve core 121 to move along the direction of the partition 1223, forcing the second elastic member 126 to deform and compress, making the gap between the second head 1211 and the partition 1223 larger, the second valve core 121 and the second seal 124 separate, the second seal 124 fails, and the second channel opens to form a passage.

[0057] In addition, when the first connector 11 and the second connector 12 are separated, the second seal 124 can seal the second channel under the pre-pressure of the second elastic member 126. Outside air can be pumped in the opposite direction from the outlet of the second channel (i.e. the side of the second accommodating cavity 1221 away from the partition 1223) to form positive pressure, preventing water backflow.

[0058] In some embodiments, a hollow shaft 1122 is provided on the side of the bottom wall 1130 of the first mounting base 113 away from the housing 2. The first connector 11 also includes a third sealing member 116, which is sleeved on the outer peripheral side of the hollow shaft 1122. When the first connector 11 is connected to the second connector 12, the hollow shaft 1122 extends into the second accommodating cavity 1221 so that the third sealing member 116 fills the space between the outer peripheral side of the hollow shaft 1122 and the inner wall of the second accommodating cavity 1221.

[0059] Optionally, the third seal 116 is made of silicone. See again. Figure 4 When the first connector 11 is connected to the second connector 12, the first channel is connected to the second channel, the hollow shaft 1122 extends into the second accommodating cavity 1221, and the third seal 116 fills the space between the outer periphery of the hollow shaft 1122 and the inner wall of the second accommodating cavity 1221. That is, the connection between the first connector 11 and the second connector 12 is sealed by the third seal 116, which can prevent leakage when the box 2 is connected to the water channel.

[0060] Figure 8 for Figure 3 The diagram shows the structure of the third seal in the liquid storage tank.

[0061] In some embodiments, the third seal 116 includes a columnar body portion 1161 and a plurality of sealing rings 1162 disposed on the outer peripheral surface of the columnar body portion 1161, the plurality of sealing rings 1162 being spaced apart along the axial direction of the columnar body portion 1161.

[0062] See Figure 8The third sealing element 116 includes a columnar body portion 1161 and a plurality of sealing rings 1162 spaced apart along the axial direction of the columnar body portion 1161. This arrangement allows the third sealing element 116 to form a multi-stage seal between the outer peripheral side of the hollow shaft 1122 and the inner wall of the second accommodating cavity 1221, further improving the connection sealing performance between the first connector 11 and the second connector 12.

[0063] In some embodiments, the flow section of the second accommodating cavity 1221 is gradually narrowed in the direction toward the third accommodating cavity 1222.

[0064] See again Figure 3 The flow section of the second accommodating cavity 1221 is gradually narrowed in the direction toward the third accommodating cavity 1222. On the one hand, it can guide the third sealing element 116 to gradually fill between the outer periphery of the hollow shaft 1122 and the inner wall of the second accommodating cavity 1221. On the other hand, the closer the third sealing element 116 is to one end of the second accommodating cavity 1221, the greater the compression of the sealing ring 1162 and the higher the sealing performance.

[0065] In some embodiments, the outer periphery of the second mounting base 123 is further provided with a mounting ear 1232, and the body of the cleaning base station is provided with a positioning hole. Fasteners are passed through the mounting ear 1232 and the positioning hole to connect the second connector 12 to the body of the cleaning base station.

[0066] See again Figure 6 Two mounting ears 1232 are provided at intervals on the outer periphery of the second mounting base 123. A positioning hole (not shown in the figure) is provided on the side of the body of the cleaning base station with the water channel installed. The second connector 12 can be connected to the body of the cleaning base station by passing the mounting ears 1232 and the positioning hole through screws or other fasteners.

[0067] In some embodiments, there are two connector assemblies 1, which are spaced apart on the housing 2 by a first connector 11. The second connector 12 of one connector assembly 1 is connected to the water inlet pipe of the water passage, and the second connector 12 of the other connector assembly 1 is connected to the water outlet pipe of the water passage.

[0068] See again Figure 1 Two connector assemblies 1 are spaced apart on the housing 2 via a first connector 11. The water circuit includes an inlet pipe and an outlet pipe. The inlet pipe is connected to the second connector 12 of one of the connector assemblies 1, and the outlet pipe is connected to the second connector 12 of the other connector assemblies 1. In this way, the inlet pipe and the outlet pipe form a circulation between the housing 2 and the water circuit, which facilitates automatic water supply and return.

[0069] In addition, this application also provides a cleaning base station, including a body and a liquid storage tank 100 according to various embodiments of this application. The body is provided with a water channel, the liquid storage tank 100 is detachably connected to the body, and the second connector 12 of the connector assembly 1 of the liquid storage tank 100 is connected to the water channel. This cleaning base station can be applied to cleaning cleaning equipment such as robotic vacuum cleaners and integrated vacuum and mop machines. Because the liquid storage tank 100 in various embodiments of this application uses the connector assembly 1 of various embodiments of this application, leakage from the water channel or the tank 2 can be prevented, thereby reducing the possibility of short circuits in the cleaning base station and ensuring high reliability.

[0070] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
