Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and in particular relates to a cleaning device. Background Technology

[0002] In daily life and industrial production, cleaning equipment (such as vacuum cleaners, sweeping machines, and robotic vacuum cleaners) is widely used in homes, offices, shopping malls, factories, and other scenarios as an important tool for maintaining environmental cleanliness. Cleaning equipment typically has a dust collection chamber to collect and temporarily store garbage, dust, and other contaminants. However, during the storage of these contaminants, which often contain large amounts of organic matter and microorganisms, bacteria can easily proliferate under suitable temperature and humidity conditions, producing odors and affecting user health and experience. Currently, antibacterial agents or substances are added to the contaminants. However, these agents or substances are mostly chemically synthesized, which can easily cause pollution. Furthermore, their effectiveness in inhibiting bacteria within the dust bag is limited. Therefore, improving the antibacterial effect within the dust bag of cleaning equipment is a crucial research area. Utility Model Content

[0003] The purpose of this application is to provide a cleaning device that can improve the antibacterial effect in the dust collection chamber of the cleaning device.

[0004] The technical solution adopted in this application embodiment is as follows: a cleaning device is provided, including a main body, an air extraction device, a first valve, and a second valve. The main body has a dust suction channel, a dust collection chamber, and an exhaust channel. The air extraction device is connected to the main body, one end of the dust suction channel is connected to the dust collection chamber, the air inlet of the air extraction device is connected to the dust collection chamber, and the air outlet of the air extraction device is connected to the exhaust channel. The first valve is connected to the main body and is used to control the opening and closing of the dust suction channel and the dust collection chamber. The second valve is connected to the main body and is used to control the opening and closing of the exhaust channel. The second valve is configured such that after the first valve is closed, the air extraction device performs an air extraction operation for a preset duration, and then the second valve is closed.

[0005] By adopting the technical solution of this embodiment, during the dust collection stage, the first valve and the second valve of the cleaning equipment are opened, and the suction device sucks in dirt through the suction channel. At this time, the dust collection chamber is connected to the dust collection component of the sweeping robot through the suction channel, and the dirt in the sweeping robot enters the dust collection chamber through the suction channel. After the dust collection is completed or at the end of the dust collection period, the first valve is closed to prevent outside air from entering the dust collection chamber. The suction device continues to extract air from the dust collection chamber, and the extracted air is discharged through the exhaust channel. After the suction device has been pumping air for a preset time, the second valve is closed to seal the exhaust channel. Through the preset time of pumping air after the first valve is closed, a negative pressure can be formed in the dust collection chamber. With the first and second valves closed, the dust collection chamber becomes a closed negative pressure space, which reduces the oxygen content in the dust collection chamber and creates an environment unfavorable to bacterial growth, thereby significantly inhibiting bacterial growth, reducing bacterial proliferation and odor generation. In addition, the negative pressure extraction used in this embodiment achieves the effect of antibacterial action, which helps to reduce the use of antibacterial substances and reduce environmental pollution.

[0006] In some embodiments, the first valve includes a valve plate and a drive member connected to the main body. The drive member is connected to the valve plate and is used to drive the valve plate to move in order to control the opening and closing of the dust suction channel and the dust collection chamber.

[0007] By adopting the technical solution of this embodiment, the valve plate can be moved by a driving component, which can realize the disconnection and connection of the dust suction channel and the dust collection chamber. Its structure is simple and easy to process and manufacture.

[0008] In some embodiments, the valve plate is provided with a connecting hole, and the driving member is used to drive the valve plate to move so as to move the connecting hole to different positions; when the connecting hole moves to communicate with the dust suction channel, the connecting hole connects the dust collection chamber and the dust suction channel; when the connecting hole moves to be misaligned with the dust suction channel, the valve plate blocks the communication between the dust suction channel and the dust collection chamber.

[0009] By adopting the technical solution of this embodiment, the valve plate can be moved by a driving component, which can achieve precise switching of the position of the connecting hole, thereby achieving precise switching of the dust suction channel and the dust collection chamber. The structure is simple and the control method is simple.

[0010] In some embodiments, the drive member is used to drive the valve plate to rotate, and the connecting hole is located on one side of the rotation axis of the valve plate.

[0011] By adopting the technical solution of this embodiment, the valve plate adopts a rotating design, which eliminates the need to reserve linear space for the valve plate to move, making it more suitable for the narrow installation environment inside the cleaning equipment and reducing interference with the layout of other components (such as suction pipes and dust collection chambers). When the valve plate rotates around the axis, the position switching path of the connecting hole is an arc. Compared with translational movement, the required driving stroke is shorter (for example, the on / off switching can be completed by rotating 90°), the response speed is faster, and it can quickly adapt to the switching needs of the cleaning equipment between dust collection mode and antibacterial mode.

[0012] In some embodiments, the valve plate has teeth around its periphery, and the first valve further includes a gear that meshes with the teeth. A drive member is connected to the gear to drive the gear to rotate.

[0013] By adopting the technical solution of this embodiment, the meshing of gears and teeth can accurately transmit the rotation angle, and the rotation angle of the valve plate can be precisely controlled, thereby improving the accuracy of opening and closing between the dust suction channel and the dust collection chamber.

[0014] In some embodiments, the first valve includes a detection element connected to the main body, and the valve plate is provided with a detection structure. When the connecting hole moves to communicate with the dust suction channel, the detection structure is positioned opposite to the detection element to trigger the detection element.

[0015] By adopting the technical solution of this embodiment, the cooperation between the detection structure and the detection component can verify in real time whether the connecting hole is connected to the dust collection channel, thereby realizing the status confirmation of whether the dust collection channel and the dust collection chamber are connected, and improving the reliability of the on / off switching.

[0016] In some embodiments, the detection structure includes a detection hole provided on the valve plate, and the detection element includes a transmitter and a receiver connected to the main body. The transmitter and the receiver are located on opposite sides of the valve plate. When the connecting hole moves to communicate with the dust suction channel, the transmitter, the detection hole and the receiver are arranged opposite to each other. The detection light emitted by the transmitter is transmitted to the receiver through the detection hole. After the receiver receives the detection light, it triggers the detection element.

[0017] Alternatively, the detection structure is a magnet located on the valve plate, and the detection element is a Hall sensor. When the connecting hole moves to connect with the dust suction channel, the Hall sensor and the magnet are positioned opposite each other, and the magnet triggers the Hall sensor.

[0018] By adopting the technical solution of this embodiment, different detection methods can be flexibly selected to meet different needs.

[0019] In some embodiments, the main body includes a suction pipe and a dust collection section connected to each other. The inner hole of the suction pipe forms a suction channel, and the dust collection section has a connected dust inlet channel and a dust collection chamber. A valve plate is disposed between the suction pipe and the dust collection section. When the connecting hole moves to communicate with the suction channel, the connecting hole connects the dust inlet channel and the suction channel. When the connecting hole moves to be misaligned with the suction channel, the valve plate blocks the communication between the dust inlet channel and the suction channel.

[0020] By adopting the technical solution of this embodiment, the valve plate is located at the connection between the dust suction pipe and the dust collection section, and the first valve is close to the dust collection chamber, which can reduce the space for the air extraction device to draw negative pressure and improve the efficiency of drawing negative pressure.

[0021] In some embodiments, a first elastic seal is provided between the inlet of the dust extraction duct and the valve plate, and / or a second elastic seal is provided between the inlet of the dust inlet channel and the valve plate.

[0022] By adopting the technical solution of this embodiment, sealing performance can be improved, and dust collection efficiency and negative pressure extraction efficiency can be increased.

[0023] In some embodiments, the main body has an exhaust port communicating with the exhaust channel; the second valve includes an exhaust damper and a resilient switch, the exhaust damper being connected to the outside of the main body via the resilient switch, the exhaust damper closing the exhaust port under the elastic action of the resilient switch; when the extraction device is turned on, the extraction device draws the gas in the dust collection chamber into the exhaust channel and pushes open the exhaust damper.

[0024] By adopting the technical solution of this embodiment, the air pressure generated by the air extraction device itself during operation is used as power, and the switching action is completed in conjunction with the reset force of the elastic switch component. This realizes the passive automatic exhaust control of the elastic switch module, which can complete the opening and closing of the exhaust port without additional drive, simplifying the structure of the elastic switch module, reducing the number of parts, and lowering the cost.

[0025] In some embodiments, the exhaust port includes a first exhaust port, the exhaust damper includes a first exhaust damper, the resilient switch includes a first resilient switch, the first resilient switch includes a rotating shaft and a torsion spring, the first exhaust damper is connected to the main body through the rotating shaft, the torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring abut against the first exhaust damper and the main body respectively.

[0026] By adopting the technical solution of this embodiment, the rotation and reset of the first row of air dampers can be realized through two components: a rotating shaft and a torsion spring. There are no complex circuits or precision components, which reduces the assembly difficulty and failure rate.

[0027] In some embodiments, the exhaust port includes a second exhaust port, the exhaust damper includes a second exhaust damper, the resilient switch includes a second resilient switch, the second resilient switch includes a connecting rod and an elastic element, one end of the connecting rod is connected to the main body, the other end of the connecting rod is provided with a blocking element, the second exhaust damper is provided with a through hole, the connecting rod passes through the through hole, the elastic element is sleeved on the connecting rod, and the two ends of the elastic element abut against the blocking element and the second exhaust damper respectively.

[0028] By adopting the technical solution of this embodiment, the second exhaust damper acts along the axial direction of the connecting rod, which can make the second exhaust damper fit more evenly with the second exhaust port and improve the sealing effect of the second exhaust port.

[0029] In some embodiments, a third elastic seal is provided at the periphery of the exhaust port, the third elastic seal being used to clamp between the exhaust door and the main body.

[0030] By adopting the technical solution of this embodiment, the setting of the third elastic seal can improve the sealing effect of the exhaust port, which is conducive to maintaining the negative pressure state of the dust collection chamber and improving the antibacterial effect.

[0031] In some embodiments, the preset duration range is 0s to 30s.

[0032] By adopting the technical solution of this embodiment, the preset time is set within the above range. After the first valve is closed, the running time of the air extraction device is reasonable, which can better balance the running time and the antibacterial effect.

[0033] In some embodiments, a dust bag is provided inside the dust collection chamber.

[0034] By adopting the technical solution of this embodiment, the dust bag, as an independent containing component, can be disassembled, replaced, or cleaned periodically, which simplifies the process of cleaning dirt with cleaning equipment, reduces the risk of users directly contacting dirt, and improves the user experience.

[0035] In some embodiments, the cleaning equipment is a base station.

[0036] By adopting the technical solution of this embodiment, the cleaning equipment can also be used directly for base stations, reducing the growth of bacteria and the generation of odors inside the base stations.

[0037] In some embodiments, the cleaning equipment includes a base station and a robotic vacuum cleaner. The base station has a main body and an air extraction device, and the other end of the suction channel is connected to the dust collection component of the robotic vacuum cleaner.

[0038] By adopting the technical solution of this embodiment, the dust suction channel is located inside the base station and is connected to the dust collection component (e.g., dust collection box) of the sweeping robot. When the sweeping robot finishes cleaning the floor and returns to the base station, the air extraction device inside the base station is activated, generating suction through the dust suction channel to draw the dirt from the sweeping robot's dust collection component into the base station's dust collection chamber. This achieves automatic dust collection, reducing the frequency of users cleaning the sweeping robot's dust collection component and improving cleaning efficiency. Furthermore, the dust collection chamber inside the base station is typically cleaned only after a long period; the negative pressure antibacterial structure of this embodiment effectively reduces bacterial growth and odor problems in the base station.

[0039] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0063] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0064] In daily life and industrial production, cleaning equipment (such as vacuum cleaners and robotic vacuum cleaners) is widely used in various scenarios such as homes, offices, shopping malls, and factories as an important tool for maintaining environmental cleanliness. Cleaning equipment is usually equipped with a dust collection chamber, which is used to collect and temporarily store garbage, dust, and other dirt, thereby achieving effective environmental cleaning.

[0065] However, during the storage of waste in the dust collection chamber, bacteria can easily proliferate due to the large amount of organic matter and microorganisms contained in the waste, under suitable temperature and humidity conditions. The proliferation of these bacteria not only produces unpleasant odors and damages the air quality of the surrounding environment, but also affects the user's health through airborne transmission and contact with equipment, significantly reducing the user experience.

[0066] To address the aforementioned problems, a solution has been proposed involving the addition of antibacterial agents or substances to waste, attempting to inhibit bacterial growth. However, this solution has significant limitations: firstly, the antibacterial agents or substances used are mostly chemically synthesized, and during the use of cleaning equipment, waste disposal, and subsequent treatment, these chemicals can easily enter the natural environment, such as soil and water, causing environmental pollution; secondly, the antibacterial agents or substances have limited effectiveness in inhibiting bacteria in the internal waste within the dust collection chamber, failing to penetrate deeply into the waste inside the chamber to exert their effect. This results in the dust collection chamber remaining a primary area for bacterial growth, failing to effectively solve the problems of bacterial proliferation and odor generation.

[0067] Therefore, how to improve the antibacterial effect in the dust collection chamber of cleaning equipment while reducing environmental pollution has become an important research topic that urgently needs to be addressed in the field of cleaning equipment. This is of great significance for improving the performance of cleaning equipment, protecting user health, and enhancing user satisfaction.

[0068] Based on this, this application proposes a cleaning device that, with the first valve closed, uses an air extraction device to extract air from the dust collection chamber for a certain period of time, creating a negative pressure inside the dust collection chamber. Then, the second valve and the air extraction device are closed, leaving the dust collection chamber in a closed negative pressure state. This reduces the oxygen content in the dust collection chamber, creating an environment unfavorable to bacterial growth, thereby significantly inhibiting bacterial growth and reducing bacterial proliferation and odor generation. Furthermore, the negative pressure extraction method used in this application achieves an antibacterial effect, which helps reduce the use of antibacterial substances and reduce environmental pollution.

[0069] The cleaning equipment described in this application is applicable to cleaning equipment with a dust collection chamber, such as: robotic vacuum cleaner, sweeping machine, vacuum cleaner, etc.

[0070] The following combination Figures 1-11 The cleaning device 1000 according to an embodiment of this application will be described.

[0071] See Figures 1-5 As shown, in some embodiments, the cleaning device 1000 includes a main body 110, an air extraction device 120, a first valve 130, and a second valve 140. The main body 110 has a dust suction channel 1111, a dust collection chamber 1121, and an exhaust channel 1131. The air extraction device 120 is connected to the main body 110. One end of the dust suction channel 1111 is connected to the dust collection chamber 1121, the air inlet of the air extraction device 120 is connected to the dust collection chamber 1121, and the air outlet of the air extraction device 120 is connected to the exhaust channel 1131. The first valve 130 is connected to the main body 110 and is used to control the opening and closing of the dust suction channel 1111 and the dust collection chamber 1121. The second valve 140 is connected to the main body 110 and is used to control the opening and closing of the exhaust channel 1131. The second valve 140 is configured such that after the first valve 130 is closed, the air extraction device 120 performs an air extraction operation for a preset duration, and then the second valve 140 is closed.

[0072] The main body 110 may refer to the main component of the cleaning equipment 1000. The main body 110 integrates a dust suction channel 1111, a dust collection chamber 1121, and an exhaust channel 1131. For example, the main body 110 includes a shell structure that surrounds and forms the dust suction channel 1111, the dust collection chamber 1121, and the exhaust channel 1131.

[0073] In some examples, the cleaning device 1000 includes a robotic vacuum cleaner 200, and the main body 110 may refer to the vacuuming part of the robotic vacuum cleaner 200. The cleaning device 1000 also includes a base station 100, and the vacuuming part of the base station 100 may be the main body 110 of the cleaning device 1000. The base station 100 works in conjunction with the robotic vacuum cleaner 200. The base station 100 has a built-in charging module. When the robotic vacuum cleaner 200's battery is low, it will automatically return to the base station 100, and the base station 100 will charge the robotic vacuum cleaner 200. For the base station 100 equipped with an automatic dust collection function, after the robotic vacuum cleaner 200 completes cleaning and returns to the base station 100, the base station 100 uses a suction device 120 to suck the debris (such as dust, debris, etc.) in the dust collection component (e.g., dust box) of the robotic vacuum cleaner 200 into the dust collection chamber 1121 inside the base station 100, avoiding the need for the user to frequently manually clean the dust collection component of the robotic vacuum cleaner 200. Some base stations 100 can also empty the wastewater tank of the sweeping robot 200 and replenish the clean water tank, realizing automatic wastewater treatment and cleaning fluid replenishment. Some base stations 100 also have functions such as automatic mop cleaning and drying (such as hot air drying and UV sterilization) and self-cleaning of the base station 100 body, further reducing manual maintenance operations for users.

[0074] In some examples, the cleaning device 1000 is a vacuum cleaner, and the vacuuming part of the vacuum cleaner is the main body 110 of the cleaning device 1000.

[0075] In some examples, the cleaning equipment 1000 is a floor scrubber, the wastewater collection part of the floor scrubber is the main body 110 of the cleaning equipment 1000, and the wastewater tank can be regarded as the dust collection chamber 1121.

[0076] For ease of explanation, the following description uses a cleaning device 1000 as an example, specifically a robotic vacuum cleaner 200 equipped with a base station 100.

[0077] The suction channel 1111 can serve as the entrance for garbage to enter the dust collection chamber 1121. One end of the suction channel 1111 is connected to the dust collection component of the sweeping robot 200, and the other end of the suction channel 1111 is connected to the dust collection chamber 1121. The suction channel 1111 is used to transport the garbage, dust and other dirt collected by the sweeping robot 200 to the dust collection chamber 1121 for temporary storage.

[0078] The dust collection chamber 1121 can be used as a space for temporary storage of dirt. A dust bag 150 can be installed in the dust collection chamber 1121. Dirt sucked in by the suction channel 1111 can be directly stored in the dust bag 150.

[0079] The exhaust passage 1131 can serve as a path for gas discharge. One end of the exhaust passage 1131 is connected to the outlet of the extraction device 120, and the other end of the exhaust passage 1131 is connected to the outside of the equipment (such as the atmosphere) to extract and discharge the air in the dust collection chamber 1121 through the extraction device 120.

[0080] The air extraction device 120 can refer to a power source used to achieve negative pressure. The air extraction device 120 can be a fan or an air pump. The air inlet of the air extraction device 120 is connected to the dust collection chamber 1121, and the air outlet of the air extraction device 120 is connected to the exhaust channel 1131. When the first valve 130 is open, the air extraction device 120 extracts the air from the dust collection chamber 1121, reducing the air pressure in the dust collection chamber 1121, so that dirt can enter the dust collection chamber 1121 for storage through the dust suction channel 1111. In addition, when the first valve 130 is closed, the air extraction device 120 can create negative pressure in the dust collection chamber 1121.

[0081] The first valve 130 is used to control the opening and closing of the dust suction channel 1111 and the dust collection chamber 1121. The first valve 130 can be installed on the dust suction channel 1111, or between the dust suction channel 1111 and the dust collection chamber 1121, or at the dust inlet of the dust collection chamber 1121. The first valve 130 is used to cut off or connect the gas passage between the dust suction channel 1111 and the dust collection chamber 1121. The first valve 130 can be a solenoid valve, a mechanical valve, etc.

[0082] The second valve 140 is used to control the opening and closing of the exhaust passage 1131. The second valve 140 can be installed on the exhaust passage 1131, at the outlet of the extraction device 120, or at the exhaust port of the exhaust passage 1131. The second valve 140 is used to cut off or connect the extraction device 120 to the outside environment. The second valve 140 can be a solenoid valve, a mechanical valve, etc.

[0083] The second valve 140 is configured such that after the first valve 130 is closed, the air extraction device 120 performs an air extraction operation for a preset time, and then the second valve 140 is closed. It can be understood that after the cleaning equipment 1000 has completed dust collection or at the end of dust collection, the first valve 130 is closed first, and then the air extraction device 120 continues to extract the gas in the dust collection chamber 1121 for a preset time before closing the second valve 140. This can create a negative pressure in the dust collection chamber 1121.

[0084] In the dust collection stage of the cleaning device 1000 of this application embodiment, the first valve 130 is opened and the second valve 140 is opened. The suction device 120 sucks in dirt through the suction channel 1111. At this time, the dust collection chamber 1121 is connected to the dust collection part 112 of the sweeping robot 200 through the suction channel 1111. The dirt in the sweeping robot 200 enters the dust collection chamber 1121 through the suction channel 1111. After dust collection is completed or at the end of the dust collection process, the first valve 130 is closed to prevent outside air from entering the dust collection chamber 1121. The air extraction device 120 continues to extract air from the dust collection chamber 1121, and the extracted air is discharged through the exhaust channel 1131. After the air extraction device 120 has been extracting air for a preset time, the second valve 140 is closed to seal the exhaust channel 1131. By extracting air for the preset time after the first valve 130 is closed, a negative pressure can be formed in the dust collection chamber 1121. With the first valve 130 and the second valve 140 closed, the dust collection chamber 1121 becomes a closed negative pressure space, which reduces the oxygen content in the dust collection chamber 1121 and creates an environment unfavorable to bacterial growth, thereby significantly inhibiting bacterial growth, reducing bacterial proliferation and odor generation. In addition, the negative pressure extraction method used in this embodiment achieves the effect of antibacterial action, which helps to reduce the use of antibacterial substances and reduce environmental pollution.

[0085] In some embodiments, the base station 100 is provided with a housing 160 to protect the base station 100, and the bottom of the base station 100 is provided with a receiving space 1001 for accommodating the sweeping robot 200.

[0086] In some embodiments, the preset duration range is 0s to 30s.

[0087] The preset duration is t, where 0s ≤ t ≤ 30s. The value of t can be 0s, 30s, or any value between 0s and 30s. For example, the value of t can be 0s, 2s, 5s, 8s, 10s, 15s, 20s, 22s, 25s, 28s, or 30s.

[0088] The larger t is, the longer the running time of the air extraction device 120 after the first valve 130 is closed, the more air is extracted from the dust collection chamber 1121, and the better the antibacterial effect in the dust collection chamber 1121. However, the longer the running time of the air extraction device 120 is, the longer the cleaning equipment 1000 runs, the higher the energy consumption, and the worse the user experience. However, within 0s≤t≤30s, the running time of the air extraction device 120 after the first valve 130 is closed is reasonable, which can better balance the running time of the cleaning equipment 1000 and the antibacterial effect.

[0089] In some examples, t=0. During the dust collection process in the dust collection chamber 1121, the air extraction device 120 extracts air from the dust collection chamber 1121, and the dust collection chamber 1121 is in a negative pressure state. Even after the first valve 130, the air extraction device 120 and the second valve 140 are closed at the same time, the dust collection chamber 1121 is still in a negative pressure state, which can also inhibit the growth of bacteria and reduce the proliferation of bacteria and the generation of odors.

[0090] By adopting the technical solution of this embodiment, after the first valve 130 is closed, the air extraction device 120 is also immediately closed, and the second valve 140 is closed. The action is rapid, the operation is simple, and the control is simple, which helps to reduce the manufacturing cost of the cleaning equipment 1000.

[0091] Please refer to the following: Figure 6 and Figure 7 As shown, in some embodiments, the first valve 130 includes a valve plate 131 and a drive member connected to the main body 110. The valve plate 131 is provided with a communication hole 1311. The drive member is connected to the valve plate 131 to control the opening and closing of the dust suction channel 1111 and the dust collection chamber 1121.

[0092] Valve plate 131 can refer to the moving part within the first valve 130, and driving component can refer to the power-providing component within the first valve 130. The driving component can be fixedly connected to the main body 110 and simultaneously connected to the valve plate 131. The driving component drives the valve plate 131 to move, and the valve plate 131 can move relative to the main body 110, thereby disconnecting or connecting the dust suction channel 1111 and the dust collection chamber 1121. The driving component can drive the valve plate 131 to flip, rotate, or move linearly, etc., and the driving component can be a motor, linear module, etc.

[0093] By adopting the technical solution of this embodiment, the valve plate 131 can be moved by a driving component, which can realize the disconnection and connection of the dust suction channel 1111 and the dust collection chamber 1121. Its structure is simple and easy to process and manufacture.

[0094] In some embodiments, the driving member is used to drive the valve plate 131 to move, thereby moving the connecting hole 1311 to different positions; when the connecting hole 1311 moves to communicate with the dust collection channel 1111, the connecting hole 1311 connects the dust collection chamber 1121 and the dust collection channel 1111; when the connecting hole 1311 moves to be misaligned with the dust collection channel 1111, the valve plate 131 blocks the communication between the dust collection channel 1111 and the dust collection chamber 1121.

[0095] The valve plate 131 is provided with a connecting hole 1311, which connects the dust suction channel 1111 and the dust collection chamber 1121. The valve plate 131 can have various shapes, such as round or square. For example, the connecting hole 1311 can penetrate the valve plate 131 along the thickness direction to connect the dust suction channel 1111 and the dust collection chamber 1121 on opposite sides of the valve plate 131.

[0096] The driving component can be fixedly connected to the main body 110 and is also connected to the valve plate 131. The driving component drives the valve plate 131 to move, so that the connecting hole 1311 is in different positions, thereby controlling the opening and closing between the dust suction channel 1111 and the dust collection chamber 1121. The driving component can drive the valve plate 131 to rotate or move linearly. The driving component can be a motor, linear module, etc.

[0097] The driving component drives the valve plate 131 to move. When the connecting hole 1311 of the valve plate 131 moves to connect with the suction channel 1111, the two ends of the connecting hole 1311 connect the suction channel 1111 and the dust collection chamber 1121 respectively, forming a complete passage. At this time, dirt in the sweeping robot 200 can enter the dust collection chamber 1121 through the suction pipe 111 and the connecting hole 1311, realizing the dust collection function of the base station 100.

[0098] The driving component drives the valve plate 131 to move, completely displacing the connecting hole 1311 from the dust collection channel 1111. At this time, the non-opening area of ​​the valve plate 131 blocks the connection between the dust collection channel 1111 and the dust collection chamber 1121. In this state, the valve plate 131 disconnects the passage between the dust collection channel 1111 and the dust collection chamber 1121, providing conditions for the subsequent air extraction device 120 to draw negative pressure into the dust collection chamber 1121 and create a low-oxygen environment.

[0099] By adopting the technical solution of this embodiment, the valve plate 131 is moved by a driving component, which can realize the precise switching of the position of the connecting hole 1311, thereby realizing the precise switching of the dust suction channel 1111 and the dust collection chamber 1121. The structure is simple and the control method is simple.

[0100] In some embodiments, the driving member is used to drive the valve plate 131 to rotate, and the connecting hole 1311 is located on one side of the rotation axis of the valve plate 131.

[0101] The valve plate 131 is rotatably mounted on the main body. A driving component drives the valve plate 131 to rotate around a fixed axis, meaning the valve plate 131 performs circular motion around a certain axis. A connecting hole 1311 is located on one side of the rotation axis of the valve plate 131, meaning the connecting hole 1311 is at a certain distance from the rotation axis and does not coincide with it. The driving component drives the valve plate 131 to rotate, causing the connecting hole 1311 located on one side of the rotation axis to rotate until it connects with the dust collection channel 1111. At this time, the connecting hole 1311 is aligned with the port of the dust collection pipe 111. At this point, the connecting hole 1311 connects the dust collection channel 1111 and the dust collection chamber 1121, allowing dirt to pass through and enter the dust collection chamber 1121 normally. The driving component drives the valve plate 131 to rotate (e.g., rotate 90° or 180°). Since the connecting hole 1311 is on one side of the axis, after rotation, the connecting hole 1311 will deviate from the port of the suction channel 1111. At this time, the non-opening area of ​​the valve plate 131 (the part without the connecting hole 1311) is opposite to the port of the suction channel 1111, thereby blocking the connection between the suction channel 1111 and the dust collection chamber 1121.

[0102] By adopting the technical solution of this embodiment, the valve plate 131 adopts a rotating design, which eliminates the need to reserve linear space for translation of the valve plate 131. This is more suitable for the narrow installation environment inside the cleaning equipment 1000 and can reduce the layout interference of other components (such as the suction pipe 111 and the dust collection chamber 1121). When the valve plate 131 rotates around the axis, the position switching path of the connecting hole 1311 is an arc. Compared with translational movement, the required driving stroke is shorter (for example, the on / off switching can be completed by rotating 90°), the response speed is faster, and it can quickly adapt to the switching needs of the cleaning equipment 1000 between the dust collection mode and the antibacterial mode.

[0103] In some embodiments, the valve plate 131 is provided with gear teeth 1312 around its periphery, and the first valve 130 further includes a gear 132, which meshes with the gear teeth 1312. A drive member is connected to the gear 132 to drive the gear 132 to rotate.

[0104] The valve plate 131 has a structure similar to the gear 132. The edge of the valve plate 131 is provided with gear teeth 1312. The gear teeth 1312 on the periphery of the valve plate 131 mesh with the gear 132. The driving component drives the gear 132 to rotate. Through the rotation of the driving gear 132, the valve plate 131 meshing with it rotates synchronously, and finally the valve plate 131 rotates.

[0105] By adopting the technical solution of this embodiment, the meshing of gear 132 and tooth 1312 can accurately transmit the rotation angle, and the rotation angle of valve plate 131 can be precisely controlled, thereby improving the accuracy of opening and closing between dust suction channel 1111 and dust collection chamber 1121.

[0106] Please refer to Figure 8. In some embodiments, the first valve 130 includes a detection element 133 connected to the main body 110. The valve plate 131 is provided with a detection structure 1313. When the connecting hole 1311 moves to communicate with the dust suction channel 1111, the detection structure 1313 and the detection element 133 are arranged opposite to each other to trigger the detection element 133.

[0107] The detection element 133 can refer to a sensor, such as a Hall sensor, photoelectric sensor, micro switch, etc. The detection element 133 is fixed on the main body 110 and is used to sense the position of the valve plate 131.

[0108] The detection structure 1313 can refer to the trigger structure provided on the valve plate 131, such as a magnet, a light shield, a protrusion, a through hole, etc. The position of the detection structure 1313 is matched with the connecting hole 1311, for example, the detection structure 1313 is located directly below or to the side of the connecting hole 1311.

[0109] When the driving component drives the valve plate 131 to rotate or translate, so that the connecting hole 1311 is accurately aligned with the dust suction channel 1111, the detection structure 1313 on the valve plate 131 will move synchronously to a position opposite to the detection element 133. At this time, the detection element 133 is triggered and outputs an electrical signal; for example: the Hall sensor is aligned with the magnet, the light path of the photoelectric sensor is blocked by the light shield, the micro switch is pressed by the protrusion, and the light path of the photoelectric sensor passes through the through hole, etc.

[0110] The output signal of the detection element 133 is received by the control system (such as MCU or PLC) of the cleaning equipment 1000. The system determines that the connecting hole 1311 is correctly connected based on the signal, and then performs subsequent operations, such as starting the air extraction device 120.

[0111] When the connecting hole 1311 moves to connect with the dust collection channel 1111, the dust collection channel 1111 and the dust collection chamber 1121 are connected. The detection structure 1313 will be set opposite to the detection element 133, thereby triggering the detection element 133 and obtaining the information that the dust collection channel 1111 and the dust collection chamber 1121 are connected.

[0112] If the connecting hole 1311 is not moved to connect with the dust collection channel 1111, then the dust collection channel 1111 and the dust collection chamber 1121 are not connected. The detection structure 1313 and the detection element 133 will not be opposite each other, and the detection element 133 will not be triggered. As a result, the information that the dust collection channel 1111 and the dust collection chamber 1121 are not connected will be obtained. The control system will identify this as the connecting hole 1311 not being properly connected, which may trigger an alarm or retry mechanism.

[0113] By adopting the technical solution of this embodiment, the cooperation between the detection structure 1313 and the detection element 133 can verify in real time whether the connecting hole 1311 is connected to the dust collection channel 1111, thereby realizing the status confirmation of whether the dust collection channel 1111 and the dust collection chamber 1121 are connected, and improving the reliability of the on / off switching.

[0114] In some embodiments, the detection structure 1313 includes a detection hole 13131 disposed on the valve plate 131, and the detection element 133 includes an emitting part 1331 and a receiving part 1332 connected to the main body 110. The emitting part 1331 and the receiving part 1332 are located on opposite sides of the valve plate 131. When the connecting hole 1311 moves to communicate with the dust suction channel 1111, the emitting part 1331, the detection hole 13131 and the receiving part 1332 are arranged opposite to each other. The detection light emitted by the emitting part 1331 is transmitted to the receiving part 1332 through the detection hole 13131. After receiving the detection light, the receiving part 1332 triggers the detection element 133.

[0115] The detection hole 13131 can refer to a through hole provided on the valve plate 131. The position of the detection hole 13131 is matched with the position of the connecting hole 1311. For example, the detection hole 13131 and the connecting hole 1311 are distributed at a fixed angle (e.g., 180°, 90°, etc.) on the valve plate 131. When the connecting hole 1311 is rotated to the position aligned with the dust suction channel 1111, the detection hole 13131 is exactly rotated into the photoelectric detection path of the detection element 133.

[0116] The emitting unit 1331 can refer to a light source used to emit detection light, such as an infrared light-emitting diode, a laser diode, etc., and the detection light can be invisible light or visible light.

[0117] The receiving unit 1332 can refer to a light signal receiver used to receive and detect light, such as a phototransistor or a photoresistor.

[0118] In some examples, the detection element 133 is a U-shaped structure, and the periphery of the valve plate 131 is located inside the U-shaped structure. The opposite side walls of the U-shaped structure form a receiving part 1332 and a transmitting part 1331, respectively. The receiving part 1332 and the transmitting part 1331 are located on both sides of the valve plate 131. When the valve plate 131 is not rotated to the position where the connecting hole 1311 is aligned with the dust suction pipe 111, the detection hole 13131 on the valve plate 131 is not aligned with the transmitting part 1331 and the receiving part 1332. At this time, the non-detection hole 13131 area of ​​the valve plate 131 will block the detection light emitted by the transmitter 1331, the receiver 1332 cannot receive the detection light, the detection element 133 is not triggered, and the detection element 133 can output a signal that the connecting hole 1311 is not in position; when the drive unit drives the valve plate 131 to rotate, so that the connecting hole 1311 is accurately aligned with the dust suction channel 1111, since the position of the detection hole 13131 and the connecting hole 1311 are related, the detection hole 13131 will rotate synchronously between the transmitter 1331 and the receiver 1332. At this time, the detection light of the transmitter 1331 is shone to the receiver 1332 through the detection hole 13131. After the receiver 1332 receives the detection light, it triggers the detection element 133 and outputs a signal that the connecting hole 1311 is in position. In this way, the position detection of the connecting hole 1311 is realized.

[0119] By adopting the technical solution of this embodiment, photoelectric detection is used to realize whether the connecting hole 1311 is connected to the dust collection channel 1111, thereby accurately confirming whether the dust collection channel 1111 and the dust collection chamber 1121 are connected, effectively improving the reliability of the on / off switching.

[0120] In some embodiments, the detection structure 1313 is a magnet disposed on the valve plate 131, and the detection element 133 is a Hall sensor. When the connecting hole 1311 moves to communicate with the dust suction channel 1111, the Hall sensor and the magnet are arranged opposite to each other, and the magnet triggers the Hall sensor.

[0121] A magnet can refer to any component that possesses magnetic properties. A Hall sensor is a magnetic field-sensitive element that operates based on the Hall effect. When current flows through a Hall element, if a magnetic field is applied perpendicular to the direction of the current, electrons will be deflected by the Lorentz force, generating a voltage difference (i.e., the Hall voltage) across the element. This voltage is proportional to the magnetic field strength, so the position of the magnet can be determined by detecting changes in the magnetic field.

[0122] The magnet moves synchronously with the valve plate 131. When the valve plate 131 moves to the alignment of the connecting hole 1311 with the dust collection channel 1111, the magnet just enters the effective sensing area of ​​the Hall sensor. At this time, the magnetic field strength exceeds the trigger threshold of the sensor, and the Hall sensor outputs a level signal, thereby accurately confirming whether the dust collection channel 1111 and the dust collection chamber 1121 are connected, and effectively improving the reliability of the on / off switching.

[0123] In some embodiments, the main body 110 includes a suction pipe 111 and a dust collection section 112 connected to each other. The inner hole of the suction pipe 111 forms a suction channel 1111. The dust collection section 112 has a dust inlet channel 1122 and a dust collection chamber 1121 connected to each other. A valve plate 131 is disposed between the suction pipe 111 and the dust collection section 112. When the connecting hole 1311 moves to communicate with the suction channel 1111, the connecting hole 1311 connects the dust inlet channel 1122 and the suction channel 1111. When the connecting hole 1311 moves to be misaligned with the suction channel 1111, the valve plate 131 blocks the communication between the dust inlet channel 1122 and the suction channel 1111.

[0124] The vacuum suction pipe 111 can be a hollow pipe, and its shape can be various, such as round pipe, flat pipe, etc. The internal channel of the vacuum suction pipe 111 forms a vacuum suction channel 1111. The vacuum suction channel 1111 formed by the vacuum suction pipe 111 has a simple structure and is easy to process and manufacture. The vacuum suction pipe 111 can be a straight pipe, a curved pipe, etc., and its specific design can be based on the actual pipeline, and is not limited here.

[0125] The dust collection section 112 can refer to the shell structure used to form the dust collection chamber 1121. A dust inlet channel 1122 is provided on one side of the dust collection section 1122, which connects the suction pipe 111 and the dust collection chamber 1121. The dust inlet channel 1122 facilitates the connection between the suction pipe 111 and the dust collection chamber 1121. The other side of the dust collection chamber 1121 is connected to the air inlet of the extraction device 120. The two sides of the dust collection chamber 1121 are respectively connected to the suction pipe 1111 and the extraction device 120, resulting in smooth airflow and improved dust collection efficiency. The driving component can be fixed to the suction pipe 111 or the dust collection section 112.

[0126] Valve plate 131 is located between suction pipe 111 and dust collection section 112. When the connecting hole 1311 moves to connect with suction channel 1111, the connecting hole 1311 connects dust inlet channel 1122 and suction channel 1111. When the connecting hole 1311 moves to be misaligned with suction channel 1111, valve plate 131 blocks the connection between dust inlet channel 1122 and suction channel 1111. It can be understood that valve plate 131 is used to control the opening and closing between suction channel 1111 and dust inlet channel 1122. When the connecting hole 1311 of valve plate 131 moves between suction channel 1111 and dust inlet channel 1122, the two ends of the connecting hole 1311 are respectively aligned with the outlet of suction pipe 111 and the inlet of dust inlet channel 1122, forming a complete passage. At this time, the dirt in the sweeping robot 200 can enter the dust collection chamber 1121 through the suction pipe 111, the connecting hole 1311, and the dust inlet channel 1122 in sequence, realizing the dust collection function of the base station 100.

[0127] The driving component drives the valve plate 131 to move, causing the connecting hole 1311 to move away from the position between the suction channel 1111 and the dust inlet channel 1122. At this time, the non-opening area of ​​the valve plate 131 will block the connection between the suction channel 1111 and the dust inlet channel 1122. In this state, the valve plate 131 disconnects the passage between the dust collection chamber 1121 and the suction pipe 111, providing conditions for the subsequent air extraction device 120 to draw negative pressure into the dust collection chamber 1121 and create a low-oxygen environment.

[0128] By adopting the technical solution of this embodiment, the valve plate 131 is located at the connection between the dust suction pipe 111 and the dust collection section 112, and the first valve 130 is closer to the dust collection chamber 1121, which can reduce the space for the suction device 120 to draw negative pressure and improve the efficiency of drawing negative pressure.

[0129] In some embodiments, the main body 110 includes a mounting portion 113, and an air extraction device 120 is mounted on the mounting portion 113. The mounting portion 113 serves as the mounting base for the air extraction device 120. An exhaust channel 1131 is formed within the mounting portion 113. The mounting portion 113 and the dust extraction pipe 111 are located on opposite sides of the dust collection portion 112. The mounting portion 113 and the dust collection portion 112 can be an integrated structure. For example, the mounting portion 113 and the dust collection portion 112 can be integrally injection molded, or the mounting portion 113 and the dust collection portion 112 can be separately formed and then assembled together. The mounting portion 113 and the dust collection portion 112 can be connected by means of threads, adhesives, or snap-fits.

[0130] In some embodiments, the mounting portion 113 may be an integrated structure formed by the housing structure of the air extraction device 120 and the channel wall of the exhaust channel 1131, thus forming a modular component that is easy to assemble and manufacture.

[0131] In some embodiments, a first elastic seal 1112 is provided between the inlet of the dust suction pipe 111 and the valve plate 131, and / or a second elastic seal 1123 is provided between the inlet of the dust inlet channel 1122 and the valve plate 131.

[0132] The first elastic seal 1112 is an elastic component installed between the opening of the suction pipe 111 and the valve plate 131. It is made of elastic materials such as rubber rings, silicone pads, and foam. The first elastic seal 1112 has a ring structure and is set around the edge of the opening of the suction pipe 111. The first elastic seal 1112 can fill the gap between the suction pipe 111 and the valve plate 131 by deformation, reducing air leakage. When the suction pipe 111 is connected to the connecting hole 1311, airflow and dirt can flow through the connecting hole 1311, improving dust collection efficiency.

[0133] The second elastic seal 1123 is an elastic component installed between the opening of the dust inlet channel 1122 and the valve plate 131. It is made of elastic materials such as rubber rings, silicone pads, or foam. The second elastic seal 1123 has a ring structure and is positioned around the edge of the opening of the dust inlet channel 1122. The second elastic seal 1123 can deform to fill the gap between the dust inlet channel 1122 and the valve plate 131, reducing air leakage. When the dust inlet channel 1122 is connected to the connecting hole 1311, airflow and dirt can flow through the connecting hole 1311, improving dust collection efficiency. Additionally, when the non-perforated area of ​​the valve plate 131 covers the opening of the dust inlet channel 1122, the second elastic seal 1123 can also deform to fill the gap between the dust inlet channel 1122 and the valve plate 131, improving sealing performance.

[0134] By adopting the technical solution of this embodiment, sealing performance can be improved, and dust collection efficiency and negative pressure extraction efficiency can be increased.

[0135] Please refer to Figures 9-11. In some embodiments, the main body 110 has an exhaust port 1130 communicating with the exhaust passage 1131; the second valve 140 includes an exhaust damper 1401 and a resilient switch 1402. The exhaust damper 1401 is connected to the outside of the main body 110 through the resilient switch 1402. The exhaust damper 1401 closes the exhaust port 1130 under the elastic action of the resilient switch 1402; when the suction device 120 is turned on, the suction device 120 draws the gas in the dust collection chamber 1121 into the exhaust passage 1131 and pushes open the exhaust damper 1401.

[0136] The exhaust port 1130 can refer to the opening that connects the exhaust passage 1131 to the outside. The exhaust port 1130 is provided on the mounting part 113 and is used to discharge the gas extracted by the suction device 120. There can be one or more exhaust ports 1130.

[0137] The exhaust damper 1401 can refer to a component used to close or open the exhaust port 1130, and the shape of the exhaust damper 1401 matches the shape of the exhaust port 1130. For example, circular, rectangular, etc.

[0138] The elastic switch 1402 can refer to a flexible connecting component, such as a spring, elastic sheet, torsion spring 14122, etc. One end of the elastic switch 1402 is connected to the exhaust damper 1401, and the other end of the elastic switch 1402 is connected to the main body 110. The elastic switch 1402 provides the exhaust damper 1401 with an elastic force to close the exhaust port 1130.

[0139] When the exhaust device 120 is working, it draws the gas from the dust collection chamber 1121 into the exhaust channel 1131. At this time, the gas flow velocity in the exhaust channel 1131 increases, forming a certain air pressure. When the air pressure in the exhaust channel 1131 is greater than the elastic force of the elastic switch 1402, the airflow pushes the exhaust damper 1401, causing it to overcome the elastic force and move away from the exhaust port 1130 (i.e., the exhaust damper 1401 is pushed open). At this time, the exhaust port 1130 opens, and the gas is discharged through the exhaust port 1130. When the exhaust device 120 continues to work, the air pressure remains, and the exhaust damper 1401 remains open, allowing the gas to be continuously discharged.

[0140] After the exhaust device 120 draws negative pressure into the dust collection chamber 1121, the exhaust device 120 is closed. The elastic force of the elastic switch 1402 will push the exhaust door 1401 to tightly fit the edge of the exhaust port 1130, sealing the exhaust port 1130. This prevents external air from flowing back into the dust collection chamber 1121 from the exhaust port 1130 and disrupting the negative pressure environment of the dust collection chamber 1121.

[0141] By adopting the technical solution of this embodiment, the air pressure generated by the air extraction device 120 during its operation is used as power, and the switching action is completed in conjunction with the reset force of the elastic switch 1402, thereby realizing the passive automatic exhaust control of the elastic switch module. The opening and closing of the exhaust port 1130 can be completed without additional drive, which simplifies the structure of the elastic switch module, reduces the number of parts, and lowers the cost.

[0142] In some embodiments, the exhaust port 1130 includes a first exhaust port 1132, the exhaust damper 1401 includes a first exhaust damper 1411, the elastic switch 1402 includes a first elastic switch 1412, the first elastic switch 1412 includes a rotating shaft 14121 and a torsion spring 14122, the first exhaust damper 1411 is connected to the main body 110 through the rotating shaft 14121, the rotating shaft 14121 passes through the first rotating hole 14111 and the second rotating hole 1133, the torsion spring 14122 is sleeved on the rotating shaft 14121, and the two ends of the torsion spring 14122 abut against the first exhaust damper 1411 and the main body 110 respectively.

[0143] The number of exhaust ports 1130 can be one or more. If there is only one exhaust port 1130, it is called the first exhaust port 1132. If there are multiple exhaust ports 1130, some of them are called the first exhaust port 1132. Alternatively, all of the exhaust ports 1130 are called the first exhaust port 1132.

[0144] The first exhaust door 1411 may refer to an exhaust door 1401 used to close the first exhaust port 1132; the first elastic switch 1412 may refer to an elastic component used to elastically push the first exhaust door 1411 to close the first exhaust port 1132.

[0145] The first air damper 1411 and the first flexible switch element 1412 form a first flexible switch module 141, which is used to open and close the first exhaust port 1132. The first exhaust port 1132 is provided in a one-to-one correspondence with the first flexible switch module 141, or multiple first exhaust ports 1132 share one first flexible switch module 141.

[0146] The first row of dampers 1411 is connected to the main body 110 via a rotating shaft 14121. It can be understood that the main body 110 has a rotating hole, and the rotating shaft 14121 is fixed to the first row of dampers 1411; or, the first row of dampers 1411 has a rotating hole, and the rotating shaft 14121 is fixed to the main body 110, with the rotating shaft 14121 inserted into the rotating hole to form a rotatable fit, thereby achieving a rotatable connection between the first row of dampers 1411 and the main body 110; or, the side of the first row of dampers 1411 has a first rotating hole 14111, and the main body 110 has a second rotating hole 1133, with the rotating shaft 14121 passing through both the first rotating hole 14111 and the second rotating hole 1133, thereby achieving a rotatable connection between the first row of dampers 1411 and the main body 110. The rotating shaft 14121 passes through the center hole of the torsion spring 14122. The two ends of the torsion spring 14122 are respectively locked on the first row of air dampers 1411 and the main body 110, forming a pre-tight torsional force.

[0147] When the exhaust device 120 is working, the gas pressure in the exhaust channel 1131 increases, and the airflow generates a thrust on the first exhaust damper 1411. When the thrust exceeds the torsional force of the torsion spring 14122, the first exhaust damper 1411 rotates around the pivot 14121 in a direction away from the first exhaust port 1132 (i.e., the first exhaust damper 1411 is pushed open). At this time, the torsion spring 14122 is further torsioned, the first exhaust port 1132 opens, and the gas is discharged. When the exhaust device 120 stops working, the airflow thrust disappears, the torsional force of the torsion spring 14122 is released, pushing the first exhaust damper 1411 to rotate in the opposite direction, returning to its initial position, resealing the first exhaust port 1132, and completing the automatic reset.

[0148] By adopting the technical solution of this embodiment, the rotation and reset of the first air damper 1411 can be realized through two components: the rotating shaft 14121 and the torsion spring 14122. There are no complex circuits or precision components, which reduces the assembly difficulty and failure rate.

[0149] In some embodiments, the exhaust port 1130 includes a second exhaust port 1134, the exhaust damper 1401 includes a second exhaust damper 1421, the elastic switch 1402 includes a second elastic switch 1422, the second elastic switch 1422 includes a connecting rod 14221 and an elastic element 14222, one end of the connecting rod 14221 is connected to the main body 110, the other end of the connecting rod 14221 is provided with a blocking element 14223, the second exhaust damper 1421 is provided with a through hole 14211, the connecting rod 14221 passes through the through hole 14211, the elastic element 14222 is sleeved on the connecting rod 14221, and the two ends of the elastic element 14222 abut against the blocking element 14223 and the second exhaust damper 1421 respectively.

[0150] The number of exhaust ports 1130 can be one or more. If there is only one exhaust port 1130, it is called the second exhaust port 1134. If there are multiple exhaust ports 1130, some of them are called the second exhaust port 1134, or all of the exhaust ports 1130 are called the second exhaust port 1134.

[0151] The second exhaust door 1421 may refer to the exhaust door 1401 used to close the second exhaust port 1134; the second elastic switch 1422 may refer to the elastic component used to elastically push the second exhaust door 1421 to close the second exhaust port 1134.

[0152] The second air damper 1421 and the second flexible switch 1422 form a second flexible switch module 142, which is used to open and close the second exhaust port 1134. The second exhaust port 1134 is provided in a one-to-one correspondence with the second flexible switch module 142, or multiple second exhaust ports 1134 may share one second flexible switch module 142.

[0153] The connecting rod 14221 serves as the skeleton of the second elastic switch 1422. The connecting rod 14221 passes through the through hole 14211 of the elastic switch 14222 and the second air damper 1421. The connecting rod 14221 connects the main body 110 and the second air damper 1421 and provides a mounting carrier for the elastic switch 14222. One end of the connecting rod 14221 is connected to the mounting part 113. A blocking member 14223 is located at the end of the connecting rod 14221 away from the mounting part 113. The blocking member 14223 can be a protrusion, nut, baffle, etc., and prevents the elastic switch 14222 and the second air damper 1421 from detaching from the connecting rod 14221.

[0154] The connecting rod 14221 may be an integral structure with at least a portion of the mounting part 113. For example, a portion of the mounting part 113 and the connecting rod 14221 may be integrally injection molded. Alternatively, the connecting rod 14221 and at least a portion of the mounting part 113 may be separately molded and then assembled together. For example, a portion of the mounting part 113 and the connecting rod 14221 may be connected by welding, screwing, or other methods.

[0155] The elastic element 14222 can be a spring. The elastic element 14222 is sleeved on the connecting rod 14221. The two ends of the elastic element 14222 abut against the blocking element 14223 and the second air door 1421 respectively. It provides the restoring force of the second air door 1421 through its own elastic deformation.

[0156] When the exhaust device 120 is turned on, the air pressure in the exhaust channel 1131 increases, and the airflow exerts an outward thrust on the second exhaust damper 1421. When the air pressure thrust is greater than the preload of the elastic element 14222, the second exhaust damper 1421 will slide away from the second exhaust port 1134 along the connecting rod 14221 (i.e., the second exhaust damper 1421 is pushed open), and further compress the elastic element 14222. At this time, a gap is generated between the second exhaust damper 1421 and the second exhaust port 1134, and the gas is discharged through the gap, thus achieving exhaust.

[0157] After the suction device 120 stops, the air pressure in the exhaust channel 1131 drops, the thrust disappears, and the compressed elastic element 14222 releases its elastic potential energy, pushing the second exhaust damper 1421 to slide along the connecting rod 14221 toward the direction closer to the second exhaust port 1134, returning to the initial position and closing the second exhaust port 1134.

[0158] For example, there are two exhaust ports 1130, one of which is the first exhaust port 1132 and the other is the second exhaust port 1134. The first exhaust port 1132 is opened and closed by the first elastic switch module 141, and the second exhaust port 1134 is opened and closed by the second elastic switch module 142. The two exhaust ports 1130 are opened and closed by different elastic methods, which helps to reduce the situation where the exhaust port 1130 cannot be opened and closed in time due to the limitation of a single elastic method.

[0159] By adopting the technical solution of this embodiment, the second exhaust damper 1421 acts axially along the connecting rod 14221, which can make the second exhaust damper 1421 fit more evenly with the second exhaust port 1134 and improve the sealing effect of the second exhaust port 1134.

[0160] In some embodiments, there are multiple connecting rods 14221, which are distributed circumferentially along the second row of dampers 1421, making the translational opening of the second row of dampers 1421 more stable. For example, there are two connecting rods 14221, which are located on the upper and lower sides of the second row of dampers 1421.

[0161] In some embodiments, the main body 110 is provided with a guide rod 1423, and the second row of air dampers 1421 is provided with a guide hole 14212. The guide rod 1423 passes through the guide hole 14212 and guides the translation of the second row of air dampers 1421 through the guide rod 1423. The second row of air dampers 1421 opens more stably along the translation of the connecting rod 14221.

[0162] In some embodiments, there are multiple guide rods 1423, which are distributed circumferentially along the second row of dampers 1421, making the translational opening of the second row of dampers 1421 along the guide rods 1423 more stable; for example, there are two guide rods 1423, which are located on the front and rear sides of the second row of dampers 1421.

[0163] In some embodiments, a third elastic seal 1435 is provided at the periphery of the exhaust port 1130, and the third elastic seal 1435 is used to clamp between the exhaust door 1401 and the main body 110.

[0164] The third elastic seal 1435 is an elastic sealing component, such as a rubber ring, silicone gasket, or elastic sealing ring. The third elastic seal 1435 is annular and surrounds the edge of the exhaust port 1130. The third elastic seal 1435 can be fixed to the periphery of the exhaust port 1130 by means of adhesive, slot embedding, etc. When the exhaust damper 1401 closes the exhaust port 1130 under the elastic force of the elastic switch 1402, the third elastic seal 1435 will be tightly clamped between the edge of the exhaust damper 1401 and the periphery of the exhaust port 1130. The third elastic seal 1435 can fill the gap between the periphery of the exhaust damper 1401 and the edge of the exhaust port 1130 through deformation, thus achieving a tight seal.

[0165] In some examples, a third resilient seal 1435 is provided at the periphery of the first vent 1130, and / or a third resilient seal 1435 is provided at the periphery of the second vent 1134.

[0166] By adopting the technical solution of this embodiment, the setting of the third elastic seal 1435 can improve the sealing effect of the exhaust port 1130, which is conducive to maintaining the negative pressure state of the dust collection chamber 1121 and improving the antibacterial effect.

[0167] In some embodiments, a dust bag 150 is provided inside the dust collection chamber 1121.

[0168] Dust bag 150 can refer to a bag-shaped structure installed inside the dust collection chamber 1121. Dust bag 150 is used to collect and contain solid particles such as dust and debris that enter the dust collection chamber 1121. Dust bag 150 can be a cloth bag, paper bag, non-woven bag, etc.

[0169] The dust bag 150 includes a bag body 152 and a switch valve 151 disposed on the bag body 152. The switch valve 151 is located at the entrance of the dust inlet channel 1122 facing away from the suction pipe 111. After the suction device 120 is activated, it generates negative pressure to suck the dirt in the dust collection component of the sweeping robot 200 into the suction pipe 111. The dirt enters the bag body 152 directly through the switch valve 151 via the suction channel 1111 and the dust inlet channel 1122. The bag body 152 is breathable, allowing gas to pass through but blocking solid particles. The filtered gas passes through the suction device 120 and is finally discharged through the exhaust channel 1131.

[0170] By adopting the technical solution of this embodiment, the dust bag 150, as an independent containing component, can be disassembled, replaced, or cleaned periodically, which simplifies the process of cleaning dirt with the cleaning equipment 1000, reduces the risk of users directly contacting dirt, and improves the user experience.

[0171] In some embodiments, the cleaning device 1000 is a base station 100.

[0172] By adopting the technical solution of this embodiment, the cleaning equipment 1000 can also be used directly for the base station 100, reducing the growth of bacteria and the generation of odors inside the base station 100.

[0173] In some embodiments, the cleaning device 1000 includes a base station 100 and a sweeping robot 200. The base station 100 has a main body 110 and an air extraction device 120. The other end of the suction channel 1111 is connected to the dust collection component of the sweeping robot 200.

[0174] By adopting the technical solution of this embodiment, the suction channel 1111 is set inside the base station 100, and the suction channel 1111 is connected to the dust collection component (e.g., dust collection box) of the sweeping robot 200. When the sweeping robot 200 finishes cleaning the floor and returns to the base station 100, the suction device 120 inside the base station 100 is activated, generating suction through the suction channel 1111 to suck the dirt in the dust collection component of the sweeping robot 200 into the dust collection chamber 1121 of the base station 100. This enables automatic dust collection, reduces the frequency of users cleaning the dust collection component of the sweeping robot 200, and improves cleaning efficiency. In addition, the dust collection chamber 1121 inside the base station 100 is usually cleaned only after a long period of time. By adopting the negative pressure antibacterial structure of this embodiment, the problem of bacterial growth and odor generation in the base station 100 can be effectively reduced.
