Both the water tank and the dust bag are detachably installed within the base station, making it convenient to change the water in the tank and replace the dust bag.

[0003] Currently, to simplify the structure, the base station of robotic vacuum cleaners includes a cavity inside for installing dust bags, which is connected to a cavity inside the base station for installing a water tank. The water tank seals the opening of the cavity for installing dust bags. When the water tank leaks, the liquid inside can easily seep into the cavity for installing dust bags inside the base station, causing the dust bags to become wet and difficult to clean.

The cover also separates the water tank from the dust bag within the second cavity, preventing leaked liquid from seeping into the second cavity in the event of a water tank leak. The water tank and the second cavity are arranged along the depth direction of the water tank, making the structure of the container more compact in the direction perpendicular to the depth direction of the water tank.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] The base station of a robotic vacuum cleaner is the core component of its intelligent cleaning system, undertaking multiple functions such as charging, self-cleaning, dust collection, and water supply and drainage. Therefore, the robotic vacuum cleaner is equipped with a water tank to hold clean and wastewater, as well as a dust bag to collect dust from the robot's dustbin. Both the water tank and the dust bag are detachably installed within the base station, making it convenient to change the water in the tank and replace the dust bag.

[0061] Currently, to simplify the structure, the dust bags in the base station of robotic vacuum cleaners are housed in a cavity inside the base station for installation. This cavity is connected to a cavity inside the base station used to house the water tank. The water tank seals the opening of the cavity for installing the dust bags. When the water tank leaks, the liquid inside can easily seep into the cavity for installing the dust bags, causing the dust bags to become wet and difficult to clean.

[0062] In the base station proposed in this application, a water tank is disposed within the first cavity of the housing, and a second cavity of the housing can be used to accommodate a removable dust bag. A negative pressure component creates a vacuum within the second cavity, allowing dust from the cleaning robot's dustbin to be sucked into the dust bag within the second cavity through the dust inlet. The dust bag within the second cavity can be removed and replaced by detaching the cover from the housing. The first and second cavities are disposed within the housing along the depth direction of the water tank, with the water tank pressing down on at least a portion of the cover. Compared to related technologies that seal the cavity for installing the dust bag using a water tank, this application, by providing a cover that is pressed down by the water tank, better separates the first and second cavities, improving the sealing performance of the second cavity and resulting in higher efficiency in sucking dust from the cleaning robot's dustbin into the dust bag. The cover also separates the water tank from the dust bag within the second cavity, preventing leaked liquid from seeping into the second cavity in the event of a water tank leak. The water tank and the second cavity are arranged along the depth direction of the water tank, making the structure of the container more compact in the direction perpendicular to the depth direction of the water tank. This makes the base station of this application occupy a smaller area and facilitates placement and installation.

[0063] The cleaning equipment proposed in this application, including the base station mentioned above, makes the cleaning equipment more efficient.

[0064] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0065] This application proposes a base station, with reference to Figures 1 to 3 As shown, it includes a housing 100, a water tank 200, a cover plate 320, and a negative pressure component 400. This base station can be used in cleaning equipment, which may include a robotic vacuum cleaner, and the cleaning robot of the cleaning equipment can be installed in the base station.

[0066] The enclosure 100 serves as the foundational component of the base station of this application. It provides a mounting base for at least some other components of the base station and protects them. The enclosure 100 can be made of metal, giving it superior structural strength and thus improved durability and reliability. Alternatively, it can be made of polymer materials, achieving a balance of structural strength and light weight. Furthermore, the enclosure 100 can also employ a combination of metal and polymer materials. Specifically, the parts of the enclosure 100 that are subject to high pressure and prone to damage can be made of metal, while other parts can be made of polymer materials, resulting in a lighter weight while maintaining reliable structural stability.

[0067] refer to Figure 2 As shown, the housing 100 has a first cavity 110 and a loading / unloading port 120. The first cavity 110 is a cavity structure within the housing 100, and the loading / unloading port 120 is located on the surface of the housing 100, allowing the loading / unloading port 120 to communicate with the first cavity 110. At least some other components of the base station can be detached and installed into the first cavity 110 via the loading / unloading port 120. The housing 100 also has a receiving cavity into which at least a portion of the cleaning robot 600 can be moved, allowing the cleaning robot 600 to be installed in the base station.

[0068] A water tank 200 is detachably disposed within the first cavity 110 of the housing 100. The water tank 200 can be used to hold cleaning water and / or wastewater. When the cleaning robot 600 is installed at the base station, the water tank 200 is connected to the cleaning robot 600, allowing the water tank 200 to supply cleaning water to the cleaning robot 600. The water tank 200 can also collect wastewater generated by the cleaning robot 600 after cleaning. The water tank 200 can be detached from the first cavity 110 through the access port 120, allowing for convenient addition of cleaning water or convenient emptying of wastewater from the water tank 200. After cleaning, the water tank 200 can be reinstalled in the first cavity 110 through the access port 120.

[0069] refer to Figure 3As shown, the housing 100 also has a second cavity 311 and a dust inlet 313. The second cavity 311 communicates with the first cavity 110 and is configured to hold a dust bag. The dust bag is detachably disposed within the second cavity 311 and can be used to collect dust. The dust inlet 313 can be connected to the dust box of the cleaning robot 600. A cover plate 320 is detachably disposed within the housing 100 and is located between the first cavity 110 and the second cavity 311. The cover plate 320 can separate the first cavity 110 from the second cavity 311 to seal the second cavity 311. A negative pressure member 400 is disposed within the housing 100 and communicates with the second cavity 311. The second cavity 311 can be used to install the dust bag. When the cleaning robot is installed at the base station, the dust box inside the cleaning robot 600 can be connected to the dust bag inside the second cavity 311 through the dust inlet. The negative pressure component 400 can draw air out of the second chamber 311, creating a negative pressure inside the second chamber 311. This allows the dust in the dust box of the cleaning robot 600 to be sucked into the dust bag, thus cleaning the dust in the dust box of the cleaning robot.

[0070] The water tank 200 and the second cavity 311 are arranged from top to bottom along the depth direction of the water tank 200, such that the bottom of the water tank 200 is opposite to at least a portion of the cover plate 320. The depth direction of the water tank 200 is... Figure 1 In the X direction, the water tank 200 and the second cavity 311 can be set up using the space of the box 100 in the height direction, and the water tank 200 can cover the cover plate 320 of the second cavity 311, which serves to limit the position of the cover plate 320. In this way, the water tank 200 can further seal the second cavity 311 of the box 100, making the sealing performance of the second cavity 311 better.

[0071] Specifically, the bottom side of the water tank 200 is pressed against the cover plate 320, so that the cover plate 320 is subjected to pressure in the direction of the second cavity 311. This makes the cover plate 320 more stable when it is placed inside the tank 100, and the cover plate 320 can seal the second cavity 311.

[0072] In related technologies, some base stations seal the cavity inside the housing 100 used for installing dust bags by sealing one side of the bottom of the water tank 200. This sealing method requires high precision in the machining of the water tank 200 and the opening of the cavity, and the water tank 200 needs to be fully installed each time it is disassembled and reassembled to ensure the sealing of the cavity. In addition, when the water tank 200 leaks liquid, the leaked liquid can easily flow directly into the cavity, causing the dust bags inside the cavity to be soaked in liquid, resulting in contamination of the cavity and dust leakage.

[0073] In this application, a cover plate 320 separates the second cavity 311 from the first cavity 110. The cover plate 320 is smaller and lighter than the water tank 200, making it easier to assemble and disassemble from the housing 100. Correspondingly, the cover plate 320 is also easier to install, allowing it to separate the first cavity 110 from the second cavity 311 and improve the sealing performance of the second cavity 311. The water tank 200 presses the cover plate 320 against the housing 100, ensuring a tight fit and further enhancing the sealing performance of the second cavity 311. When the water tank 200 leaks liquid, the cover plate 320 can prevent the leaked liquid from entering the second cavity 311, thus preventing it from seeping into the second cavity 311.

[0074] In addition, the water tank 200 and the second cavity 311 are arranged along the depth direction of the water tank 200, making the structure of the box 100 more compact in the direction perpendicular to the depth direction of the water tank 200, thus making the base station of this application occupy a smaller area and convenient for placement and installation.

[0075] In some implementations, reference Figure 2 As shown, the access port 120 of the water tank 200 in this application can be configured to face the side of the water tank 200 away from the second cavity 311. In this way, the access port 120 of the box 100 is located on the top side of the water tank 200, and the user can remove the water tank 200 from the access port 120 by lifting it. When it is necessary to replace the dust bag in the second cavity 311, the water tank 200 can be removed from the access port 120 first, then the cover plate 320 can be separated from the box 100, and finally the dust bag in the second cavity 311 of the box 100 can be removed and replaced.

[0076] When removing the dust bag, the user can also remove the dust bag from the box 100 by lifting it. During this process, the dust bag is opposite to the second cavity 311 of the box 100, so that even if the dust in the dust bag leaks out, it will fall directly into the second cavity 311, thereby preventing the dust from falling to the ground.

[0077] Furthermore, the cover 320 is concealed within the housing 100, eliminating the need for a dedicated opening on the surface of the housing 100 for dust bag installation and removal. This simplifies the structure of the housing 100, resulting in better structural stability and integration. The concealment of the cover 320 also prevents its exposure, thus preventing accidental contact that could cause it to separate from the housing 100. This allows the second cavity 311 of the housing 100 to maintain a stable negative pressure state.

[0078] In some implementations, reference Figure 4As shown, the number of water tanks 200 in this application can be set to multiple, and each of the multiple water tanks 200 can be detachably disposed within the first cavity 110 of the housing 100. The multiple water tanks 200 may include a clean water tank 200a and a wastewater tank 200b. The clean water tank 200a can be used to hold cleaning water, and the wastewater tank 200b can be used to hold wastewater. Accordingly, when the cleaning robot is installed at the base station, the cleaning robot is connected to both the clean water tank 200a and the wastewater tank 200b. The multiple water tanks 200 are arranged along a first direction, which intersects with the depth direction of the water tanks 200. The first direction is... Figure 4 The Y direction. Specifically, the first direction can be set to be perpendicular to the depth direction of the water tank 200, so that multiple water tanks 200 can be arranged laterally, thereby making full use of the lateral space in the first cavity 110 of the tank body 100 and avoiding the tank body 100 being too large in the depth direction of the water tank 200.

[0079] Multiple water tanks 200 can be positioned opposite the access ports 120 of the tank body 100, allowing for easy disassembly and installation of all tanks 200 via these ports. When the clean water tank 200a needs to be disassembled or installed via the access port 120, the wastewater tank 200b will not interfere with it. The clean water tank 200a can be directly disassembled or installed via the access port 120 without altering the state of the wastewater tank 200b. Similarly, when the wastewater tank 200b needs to be disassembled or installed via the access port 120, the clean water tank 200a will not interfere with it. The wastewater tank 200b can be directly disassembled or installed via the access port 120 without altering the state of the clean water tank 200a. This facilitates the easy disassembly and installation of both the clean water tank 200a and the wastewater tank 200b.

[0080] In other embodiments, the number of water tanks 200 can be set to one, and the water tank 200 can be provided with separate clean water chambers and wastewater chambers, so that the water tank 200 can simultaneously contain cleaning water and wastewater. This reduces the number of water tanks 200, making the structure of the base station of this application more compact.

[0081] In some implementations, reference Figure 4 As shown, the bottoms of the multiple water tanks 200 of this application are respectively opposite to at least part of the cover plate 320, so that the multiple water tanks 200 can cover the cover plate 320, so that the cover plate 320 can be fully covered by the water tanks 200, thereby making the second cavity 311 inside the tank 100 more airtight.

[0082] Specifically, the second chamber 311 can extend along the first direction, allowing it to utilize the space on one side of the bottom of the multiple water tanks 200. Correspondingly, the second chamber 311 has a relatively larger volume, and can accommodate a larger dust bag, thus allowing for a greater amount of dust to be collected. This reduces the frequency of dust bag replacement and lowers operating costs.

[0083] In some implementations, reference Figure 4 As shown, to facilitate the disassembly and separation of the cover 320 from the housing 100, a handle 321 can be provided on the side of the cover 320 facing away from the second cavity 311. The handle 321 is a protruding structure on the side of the cover 320 facing away from the second cavity 311, allowing the user to easily separate the cover 320 from the housing 100 by pulling the handle 321. The handle 321 and the cover 320 are an integral structure, resulting in better connection stability between the cover 320 and the handle 321.

[0084] In the plurality of water tanks 200, at least two adjacent water tanks 200 are provided with a gap 111, which is a gap space between two adjacent water tanks 200, and at least part of the handle 321 is located in the gap 111. In this way, the handle 321 can be offset from one side of the bottom of the water tank 200, and the handle 321 can be provided using the gap 111 between adjacent water tanks 200. The bottom side of the water tank 200 can be closer to the cover plate 320, so that the distance between the water tank 200 and the cover plate 320 is smaller. Correspondingly, the dimensions of the tank body 100 in the depth direction of the water tank 200 are smaller, and the structure is more compact.

[0085] Furthermore, when there are two or more water tanks 200, such as three, the number of gaps 111 formed between adjacent water tanks 200 is two. The number of handles 321 is also set to two, with the two handles 321 spaced apart on the side of the cover plate 320 facing away from the second cavity 311, and at least a portion of the two handles 321 can be located in the two gaps 111 respectively.

[0086] In some implementations, reference Figure 2 and Figure 6 As shown, the base station of this application may also include a cleaning fluid container 500, which is disposed within the first cavity 110 of the housing 100. The cavity within the cleaning fluid container 500 is used to contain cleaning fluid. The cleaning fluid in the cleaning fluid container 500 and the cleaning water in the water tank 200 can be mixed and diluted through pipelines to form cleaning water. The mixed and diluted cleaning water can be used to clean the mop and internal pipelines of the cleaning robot 600.

[0087] Along the depth direction of the water tank 200, the height of the cleaning fluid box 500 is lower than the height of the water tank 200, so that the cleaning fluid box 500 is located on the lower side of the water tank 200. In this way, the cleaning fluid box 500 can utilize the space inside the housing 100 located below the first cavity 110, so as to make full use of the space of the housing 100 in the depth direction of the water tank 200 and avoid the cleaning fluid box 500 affecting the installation of the water tank 200.

[0088] Specifically, the cleaning fluid container 500 can be detachably installed inside the housing 100. When it is necessary to add cleaning fluid to the cleaning fluid container 500, the cleaning fluid container 500 can be removed from the housing 100 and then the cleaning fluid can be added to the cleaning fluid container 500, making the process of adding cleaning fluid to the cleaning fluid container 500 convenient.

[0089] In some embodiments, at least a portion of the bottom of the water tank 200 in this application is opposite to the cleaning liquid box 500. The water tank 200 can cover at least a portion of the cleaning liquid box 500, thereby limiting the position of the cleaning liquid box 500 and making the cleaning liquid box 500 more stable when it is placed inside the box body 100.

[0090] Furthermore, the cleaning fluid box 500 is at least partially opposite to the bottom of the water tank 200. The cleaning fluid box 500 and the dust bag in the second cavity 311 can share the space under the water tank 200. The cleaning fluid box 500 can make full use of the space under the water tank 200, so that the cleaning fluid box 500 will not occupy additional lateral space in the water tank 200 that intersects with the depth direction of the water tank 200, such as the space in the first direction, making the dimensions of the box 100 more compact in the lateral direction that intersects with the depth direction of the water tank 200.

[0091] The bottom of the water tank 200 is spaced slightly from the cleaning solution container 500, creating a gap between them. This gap prevents the water tank 200 from pressing against the cleaning solution container 500, and consequently, the cleaning solution container 500 does not restrict the water tank 200's movement. Thus, when the water tank 200 is installed within the first cavity 110 of the housing 100, it can be fixed and limited by the limiting structure within the first cavity 110, preventing the water tank 200 from being over-limited and allowing for easier installation.

[0092] Furthermore, it should be understood that, in order to add cleaning solution to the cleaning solution container 500, a cleaning solution inlet is provided on the surface of the cleaning solution container 500. This inlet is openable and closable via a removable rubber stopper. The cleaning solution inlet is located on the side of the cleaning solution container 500 facing the bottom of the water tank 200, thus placing the inlet on the top side of the cleaning solution container 500. This also allows the water tank 200 to cover and limit the rubber stopper at the cleaning solution inlet of the cleaning solution container 500, preventing the stopper from easily falling off and thus preventing foreign objects from entering the cleaning solution container 500 and contaminating the cleaning solution.

[0093] In some embodiments, the cleaning fluid container 500 and the second cavity 311 of this application can be arranged along a second direction, which intersects both the depth direction of the water tank 200 and the first direction. The second direction is... Figure 2 and Figure 5 In the Z direction. Specifically, the depth direction, the first direction, and the second direction of the water tank 200 are perpendicular to each other. The cleaning fluid box 500 and the second cavity 311 can utilize the space of the first cavity 110 of the box 100 in the second direction. Correspondingly, the size of the second cavity 311 in the first direction is not limited by the cleaning fluid box 500, so that the size of the second cavity 311 in the first direction can be relatively larger, thereby allowing a larger volume of dust bag to be accommodated in the second cavity 311.

[0094] In addition, the cleaning fluid box 500 and the second cavity 311 are arranged along the second direction, which can also prevent the cleaning fluid box 500 and the second cavity 311 from being stacked along the depth direction of the water tank 200, thereby making the structure of the box 100 more compact in the depth direction of the water tank 200.

[0095] In some implementations, reference Figure 3 As shown, the negative pressure component 400 of this application can be disposed inside the housing 100, so that the negative pressure component 400 can be hidden inside the housing 100, thereby protecting the negative pressure component 400. The negative pressure component 400 and the second cavity 311 are disposed along the second direction, and the negative pressure component 400 and the cleaning liquid box 500 are disposed along the first direction.

[0096] Specifically, the negative pressure component 400, the second cavity 311, and the cleaning fluid box 500 are all distributed in the lateral space perpendicular to the depth direction of the water tank 200, thereby effectively utilizing the space in the first cavity 110 located below the water tank 200, allowing the various components of the base station of this application to be arranged in an orderly manner within the housing 100. The negative pressure component 400 can specifically be a fan.

[0097] In some implementations, reference Figures 3 to 4As shown, in order for the negative pressure component 400 to connect with the second cavity 311, the housing 100 may be provided with a negative pressure port 312. The negative pressure port 312 is located on the surface of the housing 100 and communicates with the second cavity 311 of the housing 100. The negative pressure component 400 communicates with the second cavity 311 of the housing 100 through the negative pressure port 312, and the negative pressure component 400 can draw air out of the second cavity 311 through the negative pressure port 312, so that the second cavity 311 can be in a negative pressure state.

[0098] The negative pressure component 400 is disposed opposite to at least a portion of the second cavity 311, and the negative pressure port 312 is located on the side wall of the second cavity 311 facing the negative pressure component 400. This allows for a smaller distance between the negative pressure component 400 and the second cavity 311, and a shorter pipe between the negative pressure component 400 and the negative pressure port 312. This makes the negative pressure component 400 more efficient at extracting air from the second cavity 311, and ultimately results in lower air pressure within the second cavity 311, leading to more efficient suction of dust collected by the cleaning robot 600 into the dust bag. The shorter pipe also reduces the manufacturing cost of the base station and simplifies its internal structure.

[0099] In addition, the negative pressure component 400 is positioned opposite to the second cavity 311, so that the negative pressure component 400 directly faces the second cavity 311, which shortens and straightens the airflow path, reduces the flow resistance of the airflow, and improves the dust collection efficiency.

[0100] In some implementations, reference Figure 4 and Figure 7 As shown, the dust inlet 313 and the negative pressure outlet 312 of this application are located on the same side wall of the second cavity 311. Correspondingly, the pipe in the base station used to connect the dust inlet 313 to the dust box of the cleaning robot 600 can be arranged along the second direction on one side of the second cavity 311 to make full use of the space of the first cavity 110 of the housing 100 in the second direction. Specifically, the pipe can be distributed along the first direction with the negative pressure component 400 and the cleaning liquid box 500, and the pipe is also located on the bottom side of the water tank 200, which makes the structure of the base station of this application more compact and occupies less space.

[0101] In some implementations, reference Figure 5 As shown, the dust inlet 313 and the negative pressure outlet 312 of this application can be located on adjacent different side walls of the second cavity 311, such that the orientation of the dust inlet 313 is different from that of the negative pressure outlet 312. Accordingly, the pipe in the base station used to connect the dust inlet 313 to the dust box of the cleaning robot 600 can be arranged on one side of the second cavity 311 in a third direction to make full use of the space of the first cavity 110 of the housing 100 in the third direction.

[0102] Specifically, the airflow within the second chamber 311 enters through the dust inlet 313 and exits through the negative pressure outlet 312. (Reference) Figure 5 As shown, by placing the dust inlet 313 and the negative pressure outlet 312 on adjacent different side surfaces of the second cavity 311, the airflow direction within the second cavity 311 is a zigzag direction, forming an L-shaped airflow path. Figure 5 The direction of the dotted line in the diagram indicates the direction of the airflow within the second cavity 311. This makes the airflow within the second cavity 311 smoother, allowing air to enter the second cavity 311 more efficiently from the dust inlet 313 and exit from the negative pressure outlet 312, thus improving the efficiency of dust being sucked from the dust box into the dust bag of the cleaning robot.

[0103] In some implementations, reference Figures 7 to 8 As shown, to ensure a more reliable connection between the cover plate 320 and the housing 100, the cover plate 320 may include a first snap-fit ​​portion 322, and the housing 100 may include a second snap-fit ​​portion 314. The first snap-fit ​​portion 322 and the second snap-fit ​​portion 314 engage, allowing for a detachable connection between them. This snap-fit ​​method enables the cover plate 320 and the housing 100 to be detachably connected, making assembly and disassembly easier and more efficient.

[0104] In some implementations, reference Figure 8 As shown, the first engaging portion 322 is a slot on the side of the cover plate 320 facing the second cavity 311, and the second engaging portion 314 protrudes from the edge of the opening of the second cavity 311 facing the cover plate 320. At least a portion of the second engaging portion 314 is embedded in the slot, so that the first engaging portion 322 and the second engaging portion 314 can mutually limit and cooperate, thereby fixing the first engaging portion 322 and the second engaging portion 314, and thus fixing the cover plate 320 to the box 100. When it is necessary to disassemble the cover plate 320 from the box 100, the cover plate 320 is lifted by the handle portion 321, so that the first engaging portion 322 disengages from the slot, thereby separating the cover plate 320 from the box 100.

[0105] To improve the sealing performance of the connection between the cover plate 320 and the housing 100, the second cavity 311 of this application further includes a sealing part 330, which is located in a slot. When the second snap-fit ​​part 314 is embedded in the slot, the second snap-fit ​​part 314 presses against the sealing part 330. In this way, the sealing part 330 can seal the area between the first snap-fit ​​part 322 and the second snap-fit ​​part 314, thereby improving the sealing performance between the first snap-fit ​​part 322 and the second snap-fit ​​part 314.

[0106] The sealing part 330 can be made of foam, allowing it to deform. The first snap-fit ​​part 322 presses against the sealing part 330, causing it to deform and thus allowing it to fit more closely to the inner wall of the slot. This ensures the sealing part 330 is relatively fully distributed between the second snap-fit ​​part 314 and the inner wall of the slot, improving the seal between the second snap-fit ​​part 314 and the slot, and consequently improving the seal of the cover plate 320 covering the second cavity 311.

[0107] Furthermore, using foam in the sealing part 330 can reduce the manufacturing cost of the sealing part 330, thereby reducing the manufacturing cost of the base station of this application. When the sealing part 330 is damaged, since the manufacturing cost of foam is low, the sealing part 330 can be directly replaced to maintain the sealing performance of the cover plate 320 covering the second cavity 311.

[0108] In some implementations, reference Figures 3 to 4 As shown, the housing 100 of this application may include a support portion 130, which is located within the first cavity 110 of the housing 100 and supports the water tank 200 along the depth direction of the water tank 200. This allows the water tank 200 to be fixed within the housing 100 in the depth direction of the water tank 200.

[0109] The support portion 130 is a stepped structure formed by the housing 100 within the first cavity 110. The support portion 130 is opposite to the bottom of the water tank 200, and the water tank 200 is pressed onto the support portion 130. By supporting the water tank 200 with the support portion 130, the water tank 200 can be limited in the depth direction, thus keeping the water tank 200 stable in the depth direction.

[0110] In some implementations, reference Figures 3 to 4 As shown, along the depth direction of the water tank 200, the height of the support 130 is higher than the height of the second cavity 311, so that the support 130 is located above the negative pressure member 400. In this way, the support 130 can avoid the second cavity 311, so that there is more space in the water tank 200 for the second cavity 311 to be installed, thereby allowing a larger volume dust bag to be installed in the second cavity 311 of the tank 100.

[0111] In some implementations, reference Figure 3 As shown, the water tank 200 and the negative pressure component 400 are located on opposite sides of the support portion 130. In this way, the support portion 130 can separate the water tank 200 from the negative pressure component 400, preventing liquid leakage from the water tank 200 from damaging the negative pressure component 400, thus achieving the purpose of protecting the negative pressure component 400.

[0112] In some embodiments, the cover plate 320 of this application is a deformable structural component. When the water tank 200 is pressed onto the cover plate 320, the cover plate 320 has a deformation toward the second cavity 311. Specifically, after being subjected to the pressure of the water tank 200, the cover plate 320 can deform, which can further make the cover plate 320 and the tank 100 more tightly connected, thereby improving the sealing effect of the cover plate 320 in sealing the second cavity 311.

[0113] In addition, refer to Figure 6 As shown, it should be understood that the base station of this application may also be provided with a water inlet docking part 140, the water tank 200 may also be provided with an interface corresponding to the water inlet docking part 140, and the cleaning robot 600 may also be provided with an interface corresponding to the water inlet docking part 140. Specifically, the water inlet docking part 140 may be provided with a clean water inlet and a wastewater inlet. The clean water inlet can dock with the interface of the clean water tank 200a, and the wastewater inlet can dock with the interface of the wastewater tank 200b. Clean water in the clean water tank 200a can be transported to the cleaning robot 600 through the clean water inlet of the water inlet docking part 140, and wastewater in the cleaning robot 600 or wastewater in the base station can be transported to the wastewater tank 200b through the wastewater inlet of the water inlet docking part 140. Since the water tank 200 is detachably connected to the tank body 100, when the water tank 200 is installed with the tank body 100, it is necessary to ensure that the interface of the water tank 200 is aligned with the water inlet docking part 140 so that the interface of the water tank 200 and the water inlet docking part 140 of the tank body 100 are fully fitted and connected.

[0114] Since the cover plate 320 is a deformable structural component, when the water tank 200 is pressed onto the cover plate 320, the cover plate 320 can deform under the pressure of the water tank 200, thereby providing the water tank 200 with more space to move in the depth direction. This prevents the cover plate 320 from over-positioning the water tank 200, allowing the water tank 200 to be mainly fixed inside the tank body 100 by the support part 130. In this way, the water tank 200 can have a certain amount of space to move by pressing the cover plate 320, so as to ensure that the interface of the water tank 200 and the water inlet docking part 140 are fully connected, thereby improving the connection and sealing performance of the interface of the water tank 200 and the water inlet docking part 140.

[0115] Specifically, the cover plate 320 can be made of polymer materials, making the cover plate 320 lighter, lower in cost, and deformable.

[0116] In some embodiments, the bottom of the water tank 200 is spaced from the cover plate 320, replacing the previous arrangement where the bottom of the water tank 200 is pressed against the cover plate 320. This prevents the water tank 200 from pressing against the cover plate 320, and consequently, the cover plate 320 does not restrict the water tank 200. Thus, when the water tank 200 is placed inside the first cavity 110 of the housing 100, it can be fixed and limited by the support portion 130 located within the first cavity 110 of the housing 100, thereby preventing the water tank 200 from being over-limited and allowing for easier installation.

[0117] When there is a gap between the bottom of the water tank 200 and the cover plate 320, so that the water tank 200 is not pressed against the cover plate 320, the sealing part 330 can be made of silicone, which can improve the sealing effect of the sealing part 330 and make the second cavity 311 fully sealed.

[0118] Furthermore, since the bottom of the water tank 200 does not contact the cover plate 320, the water tank 200 is fixed within the tank body 100 only by the support part 130 during installation. The cover plate 320 does not restrict or affect the connection between the interface of the water tank 200 and the water inlet docking part 140. This allows the water tank 200 to more easily and freely adjust its interface to connect with the water inlet docking part 140 inside the tank body 100, so that the interface of the water tank 200 and the water inlet docking part 140 can be accurately connected to improve the connection and sealing performance of the two.

[0119] In some implementations, reference Figure 9 As shown, at least a portion of the cover plate 320 of this application on the side facing away from the second cavity 311 can be configured as an arc surface 323, and the arc surface 323 is convex in the direction facing away from the second cavity 311. Thus, the cover plate 320 is convex on the side facing the water tank 200. When the water tank 200 is pressed against the cover plate 320, the water tank 200 can act on the convex structure of the arc surface 323 of the cover plate 320. The convex structure of the arc surface 323 can resist the pressure of the water tank 200 to a certain extent, thereby reducing the degree of deformation of the cover plate 320 towards the second cavity 311, thus improving the structural strength of the cover plate 320. This allows the cover plate 320 to better separate the first cavity 110 from the second cavity 311, thereby better sealing the second cavity 311.

[0120] In some implementations, reference Figure 10 As shown, a reinforcing rib 324 may also be provided on the side of the cover plate 320 facing the second cavity 311. The reinforcing rib 324 can support the cover plate 320 to improve the structural strength of the cover plate 320. When the water tank 200 is pressed on the cover plate 320, the degree of deformation of the cover plate 320 facing the second cavity 311 can be reduced, thereby improving the structural strength of the cover plate 320. This allows the cover plate 320 to better separate the first cavity 110 and the second cavity 311, and to better seal the second cavity 311.

[0121] In some implementations, reference Figure 11 As shown, the base station of this application may also include an air inlet duct 700 and a heating component. The air inlet duct 700 is connected to the dust inlet 313, and a first opening 710 on the side of the air inlet duct 700 opposite to the dust inlet 313 can be connected to the dust box of the cleaning robot 600. When the negative pressure component 400 creates a negative pressure inside the second cavity 311, dust in the dust box of the cleaning robot 600 can be sucked into the dust bag inside the second cavity 311 through the air inlet duct 700.

[0122] A heating element is installed in the housing 100 and is configured to heat the gas inside the air inlet duct 700. This allows hot air to be drawn into the second chamber 311 through the air inlet duct 700, thereby increasing the temperature inside the second chamber 311. Correspondingly, when the dustbin of the cleaning robot 600 contains wet waste, and this wet waste is drawn into the dust bag, the wet waste can be heated and dried to facilitate subsequent processing of the dust bag and reduce dust and bacteria within the second chamber 311.

[0123] In some implementations, reference Figure 11 As shown, the heating assembly of this application includes a fan 810 and a heating element 820. The air inlet pipe 700 can be a T-shaped pipe, and the air inlet pipe 700 also has a second opening 720. The air outlet side of the fan 810 is connected to the second opening 720 of the air inlet pipe 700. The fan 810 can deliver gas into the air inlet pipe 700 through the second opening 720, and the heating element 820 is configured to heat the air delivered by the fan 810, so that the fan 810 delivers hot air into the second cavity 311 through the air inlet pipe 700.

[0124] Specifically, the heating element 820 can be installed on the air inlet side of the fan 810, or it can be installed inside the air inlet pipe 700. In this way, the heating element 820 can heat the air delivered by the fan 810, thereby delivering hot gas into the second cavity 311.

[0125] Based on the base station described above, this application also proposes a cleaning device, including a cleaning robot and the base station described above. The base station housing 100 has a receiving cavity, and the cleaning robot is detachably disposed within the receiving cavity.
