Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning base station and a cleaning system. Background Art

[0002] The design of cleaning base stations is gradually moving towards integration and intelligence to improve cleaning efficiency and user experience. At present, cleaning base stations are usually equipped with electric drive modules, which are responsible for driving the water injection and sewage discharge components to realize automatic water injection and sewage discharge functions.

[0003] However, although this electric control method has achieved automation, the overall cost of the electric drive module is relatively high, and there are problems with power safety and reliability. In addition, the cleaning base station needs to meet water and electricity conditions at the same time, which limits the choice of installation location and increases the modification cost and time during the installation process. Summary of the invention

[0004] The purpose of this application is to provide a cleaning base station and a cleaning system, which can realize the function of non-electricity sewage discharge, reduce costs, improve reliability, and weaken restrictions on installation locations.

[0005] To achieve the above-mentioned objectives, the present application provides, on the one hand, a cleaning base station, which includes at least a base station body and a sewage discharge component for receiving dirt from a cleaning device, wherein the sewage discharge component is arranged on the base station body and at least partially protrudes from the outer surface of the base station body, and the sewage discharge component has a first magnetic part, which is close to one end of the sewage discharge component away from the base station body; the cleaning device moves toward the cleaning base station, and when the cleaning device recognizes the first magnetic part, the sewage discharge port of the cleaning device docks with the sewage discharge component, so that the cleaning device discharges dirt through the sewage discharge component.

[0006] To achieve the above-mentioned purpose, the present application further provides a cleaning system on the other hand, which includes a cleaning base station and a cleaning device, wherein the cleaning base station includes at least a base station body, a sewage discharge component and a preset mark, the sewage discharge component is arranged on the base station body and at least partially protrudes from the outer surface of the base station body, the sewage discharge component has a first magnetic part, the first magnetic part is close to the end of the sewage discharge component away from the base station body, and the preset mark is arranged on the base station body; a magnetic induction device is provided on the cleaning device, and the cleaning device moves toward the base station body according to a first planned path based on the preset mark, and when the cleaning device identifies the first magnetic part through the magnetic induction device, the sewage discharge port of the cleaning device is docked with the sewage discharge component, so that the cleaning device discharges sewage through the sewage discharge component.

[0007] It can be seen from this that the technical solution provided by the present application is that the cleaning equipment can determine whether the cleaning equipment has completed docking with the sewage discharge component by moving by identifying the first magnetic part provided on the sewage discharge component, so that after the cleaning equipment is docked with the sewage discharge component, the cleaning equipment can open the sewage discharge valve and / or sewage pump thereon to discharge sewage into the sewage discharge component. In this way, the present application can realize the sewage discharge function through the sewage discharge component by relying solely on the movement and control of the cleaning equipment. The cleaning base station does not need to be equipped with an electric drive module, and thus can realize non-electric sewage discharge operation, reduce costs, and improve reliability. At the same time, the cleaning base station does not need to add an additional water-electricity separation design due to the safety hazards of water-electricity contact, which further reduces manufacturing costs.

[0008] Furthermore, during installation, the installation location of the cleaning base station only needs to meet the water supply requirements, without having to meet the water and electricity requirements at the same time, thereby further reducing restrictions on the installation location and expanding the optional area for arranging the cleaning base station.

[0028] Current cleaning base stations usually have electric drive modules, which can be electric control valves, sewage pumps, etc. When the cleaning equipment is docked with the cleaning base station, the electric control valve can automatically open the injection component to inject water into the cleaning equipment, and the sewage pump can start to extract the sewage in the cleaning base station, thereby realizing the functions of injecting water and discharging sewage into the cleaning equipment.

[0029] However, the docking operations in the above methods all require electric control, which not only leads to high cost and low reliability, but also the cleaning base station needs to meet the water and electricity requirements at the same time, and the corresponding installation location must also have water and electricity, which not only limits the choice of installation location, but also increases the customer's modification cost and time during the installation process. In addition, when there are two sets of water and electricity systems in the cleaning base station at the same time, the cleaning base station must also have a corresponding water and electricity separation design to avoid the safety hazard of water and electricity contact, which will further increase the manufacturing cost.

[0030] In response to the above technical problems, the present application proposes a passive cleaning base station, which can be docked only by the movement of the cleaning equipment and the function of the magnetic induction device on the cleaning equipment to identify the magnetic parts, and realize the function of automatically replenishing clean water and discharging sewage, thereby realizing non-electric water supply and drainage operation, reducing costs and improving reliability. In addition, the installation location of the cleaning base station only needs to meet the water supply and drainage requirements, thereby further reducing the restrictions on the installation location and expanding the optional area for arranging the cleaning base station.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0032] like Figure 1 As shown, the present application provides a cleaning system, which may include a cleaning base station 1000 and a cleaning device 2000. Among them, the cleaning device 2000 (such as a commercial cleaning robot, a sweeping robot, a mopping robot, a washing and sweeping robot, an intelligent robot, a mobile robot, an automatic sweeper, and an intelligent vacuum cleaner, etc.) can be a device that can complete cleaning tasks such as sweeping, vacuuming, and mopping. The cleaning device 2000 can be remotely controlled by the user or move automatically according to certain set rules. The cleaning base station 1000 can be used for the cleaning device 2000 to dock, and provides services such as water replenishment and sewage discharge for the cleaning device 2000.

[0033] Please also see Figures 1 to 3 As shown, in an achievable implementation, the cleaning base station 1000 may include at least a base station body 100, which is the main part of the cleaning base station 1000 and is mainly used to support and protect other components of the cleaning base station 1000. In practical applications, the cleaning base station 1000 can be placed or installed on the ground independently, or it can be installed on a wall through its back.

[0034] In this embodiment, the cleaning base station 1000 may further include a sewage discharge component 400, which is used to receive dirt from the cleaning device 2000 so that the cleaning device 2000 discharges dirt to the cleaning base station 1000 through the sewage discharge component 400. Specifically, the sewage discharge component 400 is arranged on the base station body 100, and the sewage discharge component 400 at least partially protrudes from the outer surface of the base station body 100. The sewage discharge component 400 has a first magnetic part 420, and the first magnetic part 420 is close to the end of the sewage discharge component 400 away from the base station body 100. The first magnetic part 420 is used as a feedback element, and the first magnetic part 420 is used to feedback to the cleaning device 2000 whether it is docked with the sewage discharge component 400. The cleaning device 2000 moves toward the cleaning base station 1000 through its self-moving function, and when the cleaning device 2000 identifies the first magnetic member 420 , it indicates that the sewage outlet of the cleaning device 2000 is docked with the sewage discharge component 400 , so that the cleaning device 2000 can discharge sewage through the sewage discharge component 400 .

[0035] In actual application, the cleaning device 2000 is provided with a first magnetic induction device corresponding to the position of the first magnetic member 420, and a sewage valve and / or sewage pump connected to the sewage storage chamber inside the cleaning device 2000. Taking the sewage valve connected to the sewage storage chamber inside the cleaning device 2000 provided on the cleaning device 2000 as an example, when the cleaning device 2000 moves toward the cleaning base station 1000, the cleaning device 2000 identifies the first magnetic member 420 through the first magnetic induction device, and when the first magnetic induction device identifies the first magnetic member 420, it prompts that the sewage outlet of the cleaning device 2000 is connected to the sewage discharge assembly 400, and the cleaning device 2000 can stop moving further, and the cleaning device 2000 automatically opens the sewage valve, so that the dirt in the sewage storage chamber flows to the sewage discharge assembly 400 through the sewage valve and the sewage outlet to achieve sewage discharge. It can be seen that the above-mentioned entire sewage discharge action only relies on the movement and control of the cleaning equipment 2000, and the sewage discharge function can be realized through the sewage discharge component 400. The cleaning base station 1000 does not need to be equipped with an electric drive module, thereby realizing non-electric sewage discharge operation, reducing costs and improving reliability.

[0036] like Figure 2As shown, in an achievable implementation, the cleaning base station 1000 may further include a preset mark 300, which is disposed on the base station body 100. The cleaning device 2000 may determine the position of the base station body 100 through the preset mark 300, or determine the position of the sewage discharge component 400, so that the cleaning device 2000 may plan a moving path (here defined as a first planned path) for docking with the sewage discharge component 400 according to the preset mark 300. In this way, the cleaning device 2000 may move toward the base station body 100 along the first planned path based on the preset mark 300, and when the cleaning device 2000 identifies the first magnetic part 420, the cleaning device 2000 stops moving, and the water supply port of the cleaning base station 1000 just docks with the sewage discharge component 200, so that the cleaning device 2000 discharges sewage to the cleaning base station 1000 through the sewage discharge component 400.

[0037] It is worth mentioning that in the above-mentioned embodiment, the cleaning device 2000 can obtain the position of the cleaning base station 1000 through the preset mark 300 provided on the cleaning base station 1000 and plan the path to move to the base station body 100 according to the planned path, and judge whether the cleaning device 2000 is connected with the sewage discharge component 400 by moving by identifying the first magnetic part 420 provided on the sewage discharge component 400, so that after the cleaning device 2000 is connected with the sewage discharge component 400, the cleaning device 2000 can open the sewage discharge valve and / or sewage discharge pump thereon to discharge sewage to the sewage discharge component 400. In this way, the present application can only rely on the movement and control of the cleaning device 2000, and the sewage discharge function can be realized through the sewage discharge component 400. The cleaning base station 1000 does not need to be provided with an electric drive module, and can thus realize non-electric sewage discharge operation, reduce costs, and improve reliability. At the same time, the cleaning base station 1000 does not need to add an additional water-electricity separation design due to the safety hazards of water-electricity contact, further reducing manufacturing costs.

[0038] Furthermore, during installation, the installation location of the cleaning base station 1000 only needs to meet the water supply requirements, and does not need to meet the water and electricity requirements at the same time, thereby further reducing the restrictions on the installation location and expanding the optional area for arranging the cleaning base station 1000.

[0039] The preset mark 300 may be a reflective sticker. Accordingly, the cleaning device 2000 is equipped with a laser radar, so that the cleaning device 2000 identifies the position of the reflective sticker through the laser radar, and moves to the base station body 100 along the first planned path based on the position of the reflective sticker.

[0040] In practical applications, laser radar identification of reflective stickers mainly uses the high reflection intensity of reflective stickers to lasers. When the laser radar emits a laser beam and irradiates the reflective sticker, the reflective sticker will reflect the laser. Due to its special material, the intensity of the reflected laser is usually much higher than the reflection intensity of other objects in the environment. Therefore, the position of the reflective sticker can be determined by identifying the intensity of the reflected light.

[0041] The preset mark 300 may be in a specific shape or a specific color, and the specific shape may be a certain component / QR code / slot / specific color / pattern / specific shape of the base station body 100. Accordingly, the cleaning device 2000 is equipped with a camera, so that the cleaning device 2000 can use the camera to visually identify the position of the preset mark 300. The camera may be an RGB-D camera, i.e., a color depth camera, which can simultaneously capture the color image (RGB) and depth information (D) of the scene.

[0042] The cleaning base station 1000 can also have the functions of replenishing liquid and draining sewage. Figure 2 , Figure 4 and Figure 5 As shown, in an achievable embodiment, the cleaning base station 1000 further includes a liquid injection component 200, and the liquid injection component 200 is used to replenish the cleaning device 2000. Specifically, the liquid injection component 200 is arranged on the base station body 100, and the liquid injection component 200 at least partially protrudes from the outer surface of the base station body 100. The liquid injection component 200 has a liquid inlet 201, a liquid outlet 202 and a valve core 210, the liquid inlet 201 is connected to the water source, and the valve core 210 has a first position that makes the liquid inlet 201 conductive and a second position that blocks the liquid inlet 201. In other words, by adjusting the position of the valve core 210, whether the liquid inlet 201 is connected to the liquid outlet 202 can be controlled, thereby controlling whether the liquid from the water source can flow out through the liquid inlet 201 through the liquid outlet 202 to replenish the cleaning device 2000.

[0043] It should be noted that when the valve core 210 moves from the second position to the first position, the liquid inlet 201 is opened, and the liquid can flow to the liquid outlet 202 through the liquid inlet 201. When the valve core moves to the second position, the flow rate from the liquid inlet 201 to the liquid outlet 202 is the largest.

[0044] In practical applications, the liquid injection assembly 200 can replenish clean water for the cleaning device 2000, and accordingly, the water source can be a faucet or a clean water tank located at a high place, etc. The liquid injection assembly 200 can also replenish cleaning liquid for the cleaning device, and accordingly, the water source can be a cleaning liquid tank located at a high place, etc.

[0045] In this embodiment, the cleaning device 2000 can move toward the base station body 100 according to the second planned path based on the preset mark 300 to dock with the liquid injection component 200. When the cleaning device 2000 docks with the liquid injection component 200, the cleaning device 2000 forces the valve core 210 to move from the second position to the first position, so that the cleaning base station 1000 replenishes the cleaning device 2000 with liquid through the liquid injection component 200.

[0046] It is worth mentioning that although the cleaning base station 1000 has added a refilling function, the cleaning base station 1000 of the present application can also achieve the refilling function by relying solely on the movement of the cleaning device 2000. The cleaning base station 1000 does not need to actively control the water replenishment, so there is no need to set up an electric drive module, and thus can achieve non-electric water replenishment operation, reduce costs, and improve reliability. At the same time, the cleaning base station 1000 does not need to add an additional water-electricity separation design due to the safety hazards of water-electricity contact, further reducing manufacturing costs.

[0047] It should be pointed out that the "docking" defined in the present application may refer to a docking method in which two components are inserted into each other. For example, the insertion of the water injection head 262 into the water supply port of the cleaning equipment 2000 can be deemed as the completion of the docking of the water injection head 262 and the cleaning equipment 2000; it may also refer to a docking method in which two components reach a preset position relationship. For example, the sewage inlet 411 of the sewage discharge assembly 400 is located directly below the sewage discharge port of the cleaning equipment 2000.

[0048] In an achievable implementation, the liquid injection assembly 200 has a second magnetic member 290, and the second magnetic member 290 is close to an end of the liquid injection assembly 200 away from the base station body 100. In the process of the cleaning device 2000 forcing the valve core 210 to move from the second position to the first position, when the cleaning device 2000 recognizes the second magnetic member, the cleaning device 2000 stops moving, and the valve core 210 is in the second position.

[0049] In actual application, the cleaning device 2000 is provided with a second magnetic induction device corresponding to the position of the second magnetic member 290. When the cleaning device 2000 moves to the cleaning base station 1000, the cleaning device 2000 identifies the second magnetic member 290 through the second magnetic induction device, and when the second magnetic induction device identifies the second magnetic member 290, the cleaning device 2000 is prompted to stop moving, and the cleaning base station 1000 replenishes liquid to the cleaning device 2000 through the liquid injection component 200.

[0050] It should be pointed out that the magnetic induction device (such as the first magnetic induction device and the second magnetic induction device) defined in this application refers to a component for detecting a magnetic field. The magnetic induction device can output an electrical signal when a magnetic field is detected. It can use a Hall sensor or other magnetic induction elements, etc.

[0051] In an achievable implementation, the liquid injection component 200 and the sewage discharge component 400 are respectively located on different sides of the cleaning base station 1000. Accordingly, the first planned path and the second planned path are different, and the cleaning device 2000 needs to move to different sides of the cleaning base station 1000 for sewage discharge and water replenishment.

[0052] In another optional embodiment, if Figure 2 As shown, the liquid injection component 200 and the sewage discharge component 400 are located on the same side of the cleaning base station 1000. Accordingly, the first planned path and the second planned path are the same, so that the cleaning device 2000 can complete the liquid injection and sewage discharge operations on the planned path, which can simplify the operation process of the cleaning device 2000, thereby reducing the complexity of the program. The present application preferably has the liquid injection component 200 and the sewage discharge component 400 located on the same side of the cleaning base station 1000, and the subsequent description will be based on this.

[0053] In practical applications, the liquid injection component 200 is located above the sewage discharge component 400 to correspond to the upper and lower positions of the sewage discharge port and the water supply port on the cleaning device 2000. The preset mark 300 and the liquid injection component 200 can be located on different sides of the cleaning base station 1000. The preset mark 300 and the liquid injection component 200 can also be located on the same side of the cleaning base station 1000.

[0054] In a feasible implementation, when the cleaning device 2000 moves toward the base station body 100 along the first planned path based on the preset identifier 300 , the cleaning device 2000 can be docked with the sewage discharge component 400 and the liquid injection component 200 at the same time.

[0055] In another optional embodiment, when the cleaning device 2000 moves toward the base station body 100 along the first planned path based on the preset mark 300 , the liquid injection component 200 may be docked with the cleaning device 2000 before the sewage discharge component 400 .

[0056] In another optional embodiment, when the cleaning device 2000 moves toward the base station body 100 along the first planned path based on the preset mark 300 , the sewage discharge component 400 may be docked with the cleaning device 2000 before the liquid injection component 200 .

[0057] In order to allow the sewage discharge assembly 400 to dock with the cleaning device 2000 before the liquid injection assembly 200, the cleaning device 2000 can continue to move toward the cleaning base station 100 to dock with the liquid injection assembly 200. Figure 3As shown, in an achievable implementation, the sewage discharge component 400 may include a sewage receiving member 410 with telescopic rebound characteristics, the sewage receiving member 410 is provided with a sewage receiving port 411, the sewage discharge port of the cleaning device 2000 is docked with the sewage receiving port 411, and the cleaning device 2000 discharges sewage through the sewage receiving port 411. When the cleaning device 2000 recognizes the first magnetic member 420 and the cleaning device 2000 continues to move toward the base station body 1000 according to the first planned path, the cleaning device 2000 squeezes and compresses the sewage receiving member 410, so that the sewage receiving member 410 gives way, so that the water replenishment port of the cleaning device 2000 is docked with the liquid injection component 200, and at the same time, the sewage discharge port of the cleaning device 2000 is kept docked with the sewage receiving port 411. When the cleaning device 2000 is away from the sewage receiving member 410, the squeezing force on the sewage receiving member 410 disappears, and the sewage receiving member 410 automatically rebounds to the initial state.

[0058] In actual application, when the cleaning device 2000 recognizes the first magnetic member 420 through the first magnetic induction device, the cleaning device 2000 can also judge whether the dirt in its dirt storage chamber has reached the dumping position. When the cleaning device 2000 recognizes the first magnetic member 420 through the first magnetic induction device, and the dirt in the dirt storage chamber has reached the dumping position, the cleaning device 2000 discharges the dirt to the dirt receiving port 411. When the cleaning device 2000 recognizes the first magnetic member 420 through the first magnetic induction device, but the dirt in the dirt storage chamber has not reached the dumping position, the cleaning device 2000 does not discharge the dirt.

[0059] It is worth mentioning that, through the above-mentioned configuration, the cleaning device 2000 can discharge sewage alone, replenish water alone, or replenish water and discharge sewage at the same time through the cleaning base station 100.

[0060] Taking the example that the cleaning equipment 2000 only needs to discharge sewage separately, when the cleaning equipment 2000 moves to the cleaning base station 1000 according to the first planned path, when the cleaning equipment 2000 identifies the first magnetic part 420 through the first magnetic induction device, the cleaning equipment 2000 stops moving, the sewage outlet of the cleaning equipment 2000 is docked with the sewage receiving port 411, and the cleaning equipment 2000 discharges sewage to the sewage receiving port 411.

[0061] Taking the cleaning device 2000 as an example, when the cleaning device 2000 moves toward the cleaning base station 1000 according to the first planned path, when the cleaning device 2000 identifies the first magnetic part 420 through the first magnetic induction device, the dirt in the dirt storage chamber has not reached the dumping position, and the cleaning device 2000 does not discharge dirt. The cleaning device 2000 further moves toward the base station body 100 by a preset distance, and the water supply port of the cleaning device 2000 docks with the liquid injection component 200. The cleaning base station 1000 replenishes the cleaning device 2000 with water through the liquid injection component 200, and identifies the second magnetic part 290 through the second magnetic induction device, and the cleaning device 2000 stops moving further.

[0062] Taking the cleaning device 2000 as an example, when the cleaning device 2000 moves toward the cleaning base station 1000 according to the first planned path, when the cleaning device 2000 identifies the first magnetic member 420 through the first magnetic induction device, since the dirt in the dirt storage chamber reaches the dumping position, the cleaning device 2000 discharges dirt to the dirt receiving port 411. While the cleaning device is discharging dirt to the dirt receiving port 411, the cleaning device 2000 further moves toward the base station body 100 by a preset distance, and the water replenishment port of the cleaning device 2000 docks with the liquid injection component 200. The cleaning base station 1000 replenishes the cleaning device 2000 with water through the liquid injection component 200, and identifies the second magnetic member 290 through the second magnetic induction device, and the cleaning device 2000 stops moving further, so that the cleaning device 2000 can replenish water and discharge dirt at the same time.

[0063] In practical applications, the dirt receiving member 410 may at least partially protrude from the side of the base station body 100, and the dirt receiving port 411 is located above the dirt receiving member 410. The dirt receiving member 410 is formed with a sewage trough, and the bottom end of the sewage trough flows to the sewage containing area through the sewage discharge pipe 430, wherein the sewage containing area may be a sewage tank or a sewer, etc. The sewage containing area is located below the sewage trough, so that when the cleaning device 2000 discharges sewage into the sewage trough through the sewage receiving port 411, the dirt can automatically flow into the sewage containing area under the action of its own gravity, thereby eliminating the need for an additional sewage extraction device.

[0064] Regarding the specific structure of the dirt receiving member 410 with telescopic and resilient properties, in a feasible implementation, the dirt receiving member 410 may be made of a soft resilient material in one piece.

[0065] In practical applications, the end of the inner wall of the dirt receiving member 410 away from the base station body 100 is a slope structure, and the slope structure is arranged downwardly in the direction of the base station body 100, so as to facilitate the received dirt to flow smoothly into the base station body 100, and then flow to the dirt containing area through the sewage pipe 430. The dirt receiving member 410 can have a corrugated section, so that the corrugated section is used to limit the compression deformation of the dirt receiving member 410 in a specific direction, ensure the compression stability of the dirt receiving member 410, and ensure that it has a stable displacement and restoring force at the end of compression.

[0066] In another optional embodiment, the sewage receiving member 410 can also be formed by combining two sections of support members, a plastic member and a spring. The plastic member is connected between the two sections of support members to form a container with an opening, and the opening is the sewage receiving port 411. One support member is fixed on the base station body 100, and the other support member can move toward or away from the base station body 100 by utilizing the deformability of the plastic member. The spring is connected between the other support member and the base station body 100, so that the spring provides the other support member with a reset force for moving in a direction away from the base station body 100.

[0067] like Figure 3 As shown, in an achievable embodiment, the sewage discharge assembly 400 further includes a filter screen 440 , which is detachably connected to the sewage receiving member 410 to filter the dirt in the sewage receiving member 410 , thereby preventing the dirt from clogging the sewage discharge pipe 430 .

[0068] Specifically, the filter 440 is disposed between the portion of the dirt receiving member 410 disposed outside the base station body 100 and the portion disposed inside the base station body 100, so that larger granular dirt can be blocked outside the base station body 100 to facilitate cleaning by the user. At the same time, the filter 440 is prevented from hindering the deformation of the dirt receiving member 410, thereby ensuring the functionality of the dirt receiving member 410.

[0069] Regarding the specific structure of the liquid injection component 200, Figures 4 to 9As shown, in an achievable implementation, the injection assembly 200 may further include an access tube 220, a receiving tube 230 and a reset member 240. The access tube 220 is fixed on the base station body 100, and the liquid inlet 201 is provided at the first end of the access tube 220. The receiving tube 230 is sleeved on the second end of the access tube 220, and the receiving tube 230 is connected to the second end of the access tube 220, and the liquid outlet 202 is provided at one end of the receiving tube 230 away from the access tube 220 or downstream thereof. The receiving tube 230 has an inner step surface 231, and the valve core 210 is slidably connected in the access tube 220 and the receiving tube 230. When the valve core 210 is in the second position, the valve core 210 abuts against the inner step surface 231, thereby blocking the liquid inlet 201. The reset member 240 is disposed in the access pipe 220 and connected to the valve core 210 , and the reset member 240 is used to provide a reset force for the valve core 210 to move from the first position to the second position.

[0070] In this embodiment, when the cleaning device 2000 moves toward the base station body 100 along the first planned path based on the preset mark 300, the cleaning device 2000 squeezes and forces the valve core 210 to move from the second position to the first position, thereby squeezing and compressing the reset member 240 through the valve core 210. After the cleaning device 2000 is replenished with liquid, as the cleaning device 2000 moves away, the squeezing force of the cleaning device on the valve core 210 disappears. At this time, the reset member 240 returns from the compressed state to the initial state, and the reset member 240 drives the valve core 210 to move from the first position to the second position. The valve core 210 abuts against the inner step surface 231, so that the liquid injection component 200 can be automatically blocked to prevent the liquid from continuing to flow out of the liquid injection component 200, so that the liquid injection component 200 can achieve the effect of automatically stopping the water after being separated from the cleaning device 2000.

[0071] In practical applications, the outer wall surface of the second end of the access pipe 220 may be provided with a thread, and the access pipe 230 may be sleeved on the second end of the access pipe 220 by being threadedly connected with the second end of the access pipe 220. Of course, the access pipe 230 may also be sleeved on the second end of the access pipe 220 by hot-melt connection, welding or bonding. The inner step surface 231 may be formed by the end surface of an annular protrusion protruding radially inward from the inner wall surface of the access pipe 230. The access pipe 230 may also be constructed as a stepped pipe structure, and the inner wall surface of the connecting part of two adjacent pipes of the stepped pipe forms the inner step surface 231. Among them, the reset member 240 may be a spring or an elastic block.

[0072] In order to further ensure the blocking effect of the valve core 210 on the liquid inlet 201 when the valve core 210 is in the second position, in an achievable embodiment, the liquid injection assembly 200 may further include an annular sealing member 250. The access tube 220 has a first end face 221 close to the access tube 230, the sealing member 250 is limited between the inner step face 231 and the first end face 221, and the sealing member 250 protrudes radially inward from the inner wall surface of the access tube 220. In this way, when the valve core 210 is in the second position, the valve core 210 can abut against the inner step face 231 through the sealing member 250, thereby ensuring the sealing effect of the valve core 210 and the inner step face 231, that is, the blocking effect of the liquid inlet 201.

[0073] Preferably, the inlet pipe 220 and the outlet pipe 230 may be connected in a detachable manner such as threaded connection to facilitate subsequent maintenance and replacement of the sealing member 250 .

[0074] In an achievable implementation, when the valve core 210 is in the second position, the valve core 210 can be retracted into the receiving pipe 230. Accordingly, a component on the cleaning device 2000 or a component on the cleaning base station 1000 is pushed by the cleaning device 2000 to extend into the receiving pipe 230, pushing the valve core 210 to slide from the second position to the first position.

[0075] In another optional embodiment, if Figure 5 As shown, when the valve core 210 is in the second position, the valve core can partially protrude from the access pipe 230. In this way, the cleaning device 2000 can be easily pushed against the valve core 210, so that the valve core 210 moves from the second position to the first position, and the cleaning device 2000 or the cleaning base station 1000 does not need to be provided with a component for extending into the access pipe 230, thereby simplifying the structure.

[0076] In practical applications, such as Fig. 9 As shown, the valve core 210 may include a stop plate 211 and a driving pipe 212. The stop plate 211 is provided at one end of the driving pipe 212 and blocks the opening of one end of the driving pipe 212. The stop plate 211 extends outward from the outer wall surface of the driving pipe 212. The driving pipe 212 is provided with a connecting hole 213 connecting the inside and the outside of the driving pipe 212 in the circumferential direction. The stop plate 211 is provided with a sealing member 250 on one side close to the access pipe 220. The driving pipe 212 passes through the sealing member 250 and the access pipe 230 and extends from one end of the access pipe 230 away from the access pipe 220. When the valve core 210 is in the second position, the stop plate 211 abuts against the sealing member 250, thereby ensuring the cut-off effect of the liquid inlet 201 and the liquid outlet 202. When the valve core 210 is in the first position, the liquid in the access pipe 220 can flow to the access pipe 230 through the connecting hole 213 and the driving pipe 212.

[0077] Please see again Figure 5 and Figure 8 As shown, in an achievable embodiment, the liquid injection assembly 200 may further include a telescopic pipe 260, wherein the telescopic pipe 260 includes a telescopic pipe portion 261 and a water injection head 262. The telescopic pipe portion 261 has a telescopic and resilient property, one end of the telescopic pipe portion 261 is sleeved on the outer wall surface of the end of the access pipe 230 away from the access pipe 220, and one end of the telescopic pipe portion 261 is connected to the access pipe 230. The water injection head 262 is provided at the other end of the telescopic pipe portion 261, and the above-mentioned liquid outlet 202 is provided on the water injection head 262, and the liquid outlet 202 is connected to the telescopic pipe portion 261. When the cleaning device 2000 identifies the first magnetic part 420 and continues to move toward the base station body 100 along the first planned path, the cleaning device 2000 squeezes the telescopic tube portion 261 through the water injection head 262 to cause the telescopic tube portion 261 to contract, thereby causing the water injection head 262 to abut against the valve core 210 and squeeze the valve core 210 to move from the second position to the first position, and then the liquid injection assembly 200 can replenish liquid to the cleaning device 2000.

[0078] It should be pointed out that, precisely because the telescopic tube 261 also has a rebound characteristic, after the cleaning device 2000 is filled with liquid, the cleaning device 2000 can retreat a distance and stay for a period of time. During this process, the telescopic tube 260 is released, and the telescopic tube 260 automatically rebounds. At the same time, the valve core 210 also moves from the first position to the second position to reseal and stop water injection. However, the water injection head 262 is still located in the cleaning device 2000, and the residual liquid in the telescopic tube 260 will continue to flow to the cleaning device 2000, thereby preventing the residual liquid in the telescopic tube 260 from flowing to the ground when the valve core 210 is closed, causing secondary pollution.

[0079] In practical applications, the telescopic tube 261 may be a bellows structure made of a soft resilient material, so that the telescopic tube 261 can be folded and contracted after being squeezed, and when the squeezing force disappears, the telescopic tube 261 rebounds and expands. The telescopic tube 261 and the water injection head 262 may be integrally formed by secondary injection molding, or the telescopic tube 261 and the water injection head 262 may be designed as separate parts and then connected to each other.

[0080] In an achievable implementation, a rib may be provided at one end of the water injection head 262 adjacent to the telescopic tube 261, and the rib does not block the water path in the water injection head 262. When the water injection head 262 moves toward the valve core 210, the water injection head 262 may utilize the high strength of the rib to squeeze the valve core 210, driving the valve core 210 to move from the second position to the first position. In practical applications, the rib may be formed in the water injection head 262 by insert injection molding, or may be subsequently connected to the water injection head 262.

[0081] The opening direction of the liquid outlet 202 should be set according to the corresponding water supply port of the cleaning device 2000, wherein the liquid outlet 202 can be set to open downward, so that the height of the clean water inside the cleaning device 2000 is lower than the liquid outlet 202, thereby facilitating the injection of water into the cleaning device 2000 through the liquid injection assembly 200. Of course, the liquid outlet 202 can also be set to open obliquely upward, or the axis of the liquid outlet 202 can also be parallel to the horizontal direction, which is not specifically limited in this application.

[0082] In order to avoid the water injection head 262 from being misaligned after the telescopic tube 260 is retracted, which may affect the normal docking of the liquid injection assembly 200 with the cleaning device 2000, please refer to Figure 5 and Figure 8 As shown, in an achievable implementation, the liquid injection assembly 200 may further include a fixed sleeve 270 and an auxiliary telescopic tube 280, the fixed sleeve 270 is connected to the base station body 100, and the fixed sleeve 270 is located outside the access tube 220 and is coaxially arranged with the access tube 220. The auxiliary telescopic tube 280 is slidably connected to the fixed sleeve 270 along the axis of the access tube 220, and the water injection head 262 is fixed on the auxiliary telescopic tube 280. In this way, the water injection head 262 slides along the axis of the access tube 220 under the cooperation of the auxiliary telescopic tube 280 and the fixed sleeve 270 to ensure the consistency of the position of the water injection head 262 after the telescopic tube 260 is contracted and expanded, to ensure the normal docking of the liquid injection assembly 200 with the cleaning equipment 2000 in the future, and to improve the reliability of the cleaning base station 1000.

[0083] In practical applications, the first magnetic member 420 can be embedded in the end of the dirt receiving member 410 away from the base station body 100, and the second magnetic member 290 can be installed at the end of the fixed sleeve 270 away from the access pipe 220. When the ribs initially contact the valve core 210, the distance between the water injection head 262 and the fixed sleeve 270 is greater than the telescopic stroke of the reset member 240, so that the ribs can have enough stroke to compress the reset member 240, so that the valve core 210 moves from the first position to the second position.

[0084] In another optional embodiment, the telescopic tube 260 may only have a telescopic property but not a rebound property. Accordingly, an elastic member may be provided between the auxiliary telescopic tube 280 and the fixed sleeve 270, so as to realize the rebound and reset function of the telescopic tube 260 by utilizing the elastic member between the auxiliary telescopic tube 280 and the fixed sleeve 270.

[0085] like Figure 2 and Figure 4As shown, in an achievable implementation, the base station body 100 may include a main body 110 and an extension tube 120, the extension tube 120 at least partially extending outward from the main body 110, and the access tube 220 and the fixed sleeve 270 are fixedly connected to the extension tube 120. This design can reduce the size of the clean base station 1000 and save costs.

[0086] In practical applications, the extension tube 120 is a rigid structure, which is used to support and fix the access tube 220 and the fixed sleeve 270. A liquid inlet pipe 121 may also be provided inside the extension tube 120, and the liquid inlet pipe 121 of the extension tube 120 plays a protective role, and the liquid inlet 201 is connected to the water source through the liquid inlet pipe 121.

[0087] Further, such as Fig.10 As shown, the cleaning base station 1000 may further include a shell 130, which completely covers the main body 110 and the extension tube 120, so that the liquid injection component 200 extends out of the shell 130 alone. In this way, when the cleaning device 2000 collides and squeezes the liquid injection component 200, the cleaning device 2000 exerts an impact force on the liquid injection component 200, and the liquid injection component 200 can partially transfer the impact force to the shell 130 to reduce the impact force on the extension tube 120, thereby increasing the impact force of the cleaning device 2000 that the cleaning base station 1000 can withstand.

[0088] Please see again Figure 2 and Fig.11 As shown, in an achievable implementation, the cleaning base station 1000 further includes a water spray assembly 500, which is mounted on the outer surface of the base station body 100, and the water spray assembly 500 is connected to a water source, so that the liquid provided by the water source can be sprayed through the water spray assembly 500 to rinse the cleaning device 2000. In practical applications, the water spray assembly 500 may include a water spray head 510 and a hose 520, and the water spray head 510 is connected to the water source through the hose 520. In this way, the hose 520 can provide more activity space for the water spray head 510, and the user can take the water spray head 510 and operate it at any position and angle within the length of the hose 520.

[0089] like Fig.11As shown, in an achievable implementation, a tee 140 and a main pipe 150 may be installed inside the base station body 100, wherein the tee 140 is normally open in all directions, the sprinkler head 510 has a switch to control opening and closing, one port of the tee 140 is connected to the water source through the main pipe 150, the other port of the tee 140 is connected to the sprinkler head 510 through the hose 520, and another port of the tee 140 is connected to the liquid inlet 201 through the liquid inlet pipe 121. In this way, only one pipeline can be set inside the base station body 100 to connect to the water source, thereby simplifying the pipeline inside the base station body 100 and reducing the production cost.

[0090] Based on the same inventive concept, the present application also provides a cleaning system, which includes a cleaning base station 1000 and a cleaning device 2000, wherein the cleaning base station 1000 may at least include a base station body 100, a sewage discharge component 400 and a preset mark 300, and the sewage discharge component 400 is arranged on the base station body 100 and at least partially protrudes from the outer surface of the base station body 100. The sewage discharge component 400 has a first magnetic member 420, the first magnetic member 420 is close to one end of the sewage discharge component 400 away from the base station body 100, and the preset mark 300 is arranged on the base station body 100. A magnetic induction device is provided on the cleaning device 2000, and the cleaning device 2000 moves toward the base station body 100 according to the first planned path based on the preset mark 300, and when the cleaning device 2000 identifies the first magnetic member 420 through the magnetic induction device, the sewage discharge port of the cleaning device 2000 docks with the sewage discharge component 400, so that the cleaning device 2000 discharges sewage to the sewage discharge component 400.

[0091] It should be pointed out that the specific structures of the base station body 100, the sewage discharge component 400 and the preset mark 300 can refer to the contents in the above-mentioned embodiment and will not be repeated here.

[0092] The following is a detailed description based on specific application scenarios, taking the cleaning equipment as a commercial cleaning robot and its use in conjunction with a cleaning base station as an example.

[0093] Application scenario 1

[0094] A shopping mall purchased a cleaning system, which consists of a cleaning base station and a commercial cleaning robot. The cleaning base station provides automatic water replenishment and sewage discharge functions for the commercial cleaning robot. The cleaning base station is affixed with a reflective sticker, and the cleaning base station only has two pipes extending outward, one of which is used as a liquid inlet pipe to connect to the faucet, and the other is used as a drain pipe to connect to the sewer, which just meets the problem of no power plug reserved in the installation area of ​​the cleaning base station.

[0095] When the commercial cleaning robot returns to the base station to discharge sewage, the commercial cleaning robot uses the built-in laser radar to identify the position of the reflective sticker and continuously moves closer to the cleaning base station in a set direction. When the magnetic induction device at the sewage outlet of the commercial cleaning robot detects the magnetic field of the first magnetic part, the sewage outlet and the sewage receiving part are docked, and the commercial cleaning robot discharges sewage into the sewage receiving part. After the sewage discharge is completed, the commercial cleaning robot leaves the cleaning base station to complete the sewage discharge operation.

[0096] When the commercial cleaning robot returns to the base station to discharge sewage, the commercial cleaning robot identifies the position of the reflective sticker through the built-in laser radar, and continuously moves close to the cleaning base station in a set direction. When the magnetic induction device at the sewage outlet of the commercial cleaning robot detects the magnetic field of the first magnetic part, the commercial cleaning robot continues to move toward the cleaning base station until the magnetic induction device at the water supply port of the commercial cleaning robot detects the magnetic field of the second magnetic part, and then the commercial cleaning robot stops moving. During this process, the sewage receiving part is squeezed and contracted, but the sewage outlet and the sewage receiving part are still in the docking position. The commercial cleaning robot can decide whether to discharge sewage according to the amount of sewage. At the same time, the telescopic pipe is squeezed and contracted toward the valve core, and the rib position pushes the valve core to overcome the reset force of the reset part and the water pressure and switch from the second position to the first position, so that the water flow from the faucet can flow to the water supply port through the valve core and the telescopic pipe to replenish water for the commercial cleaning robot. After the commercial cleaning robot has finished replenishing water, it will retreat for a distance. During this process, the telescopic pipe fitting is released and rebounds. At the same time, the valve core is reset under the action of the reset member, and the water injection is stopped. However, the water injection head of the telescopic pipe fitting is still located in the water replenishment port of the commercial cleaning robot. The residual water flow in the telescopic pipe fitting will continue to flow into the commercial cleaning robot to avoid flowing onto the ground. After staying for a period of time, the commercial cleaning robot is completely separated from the cleaning base station, and the dirt collecting part and the telescopic pipe fitting automatically rebound to their original state.
