Description

Technical Field

[0001] This application belongs to the field of cleaning device technology, specifically relating to a channel switching component, a cleaning base station, a cleaning system, and a self-cleaning method. Background Technology

[0002] To handle both dry and wet waste, existing integrated base stations are typically equipped with independent high-power fans and drainage pipes to process wet waste, while also having independent dust collection fans and dust collection channels to collect dry waste. The dual-fan structure increases the manufacturing cost, size, and energy consumption of the base station, and is prone to fan failures, making maintenance inconvenient.

[0003] To address the problems inherent in dual-fan structures, single-fan base stations that utilize duct switching structures for switching between dust and liquid collection functions have been introduced to the market. However, existing duct switching structures largely rely on spring force or manual operation, lacking precise limit and positioning mechanisms. The rotational movement of the switching components is not effectively constrained, leading to positioning deviations during switching. This results in poor duct switching accuracy and stability, causing issues such as poor sealing performance and significant suction loss, thus affecting the base station's self-cleaning effect. Summary of the Invention

[0045] In one or more embodiments, the drive member includes a limit switch for detecting the rotation angle of the valve plate, and the step of controlling the valve plate to rotate along a first direction to the second rotation angle by the drive member includes:

[0046] The valve plate is controlled to rotate in the first direction by the drive component until a signal is received from the limit switch, at which point the drive component stops working.

[0047] In one or more embodiments, the step of controlling the valve plate to rotate along the second direction to the first rotation angle via the drive member includes:

[0048] The valve plate is controlled to rotate in the second direction by the drive component until a signal is received from the limit switch, at which point the drive component stops working.

[0049] The advantages of this application, which differ from existing technologies, are:

[0050] The channel switching component of this application can achieve air duct switching by rotating the valve plate. The rotational movement is simple and direct, the power transmission path is short, which improves the response speed and reliability, and the switching process is smooth.

[0051] In the channel switching assembly of this application, the valve plate abuts against the inner wall of the housing at both the first and second rotation angles, which can ensure the overall sealing of the air duct and effectively avoid suction loss.

[0052] When the valve plate of the channel switching component of this application is rotated to the correct position, the valve plate abuts against the inner wall of the housing and is limited by the housing, which can ensure the accuracy and stability of the air duct switching.

[0053] In the channel switching component of this application, the extension direction of the second branch channel near the main channel is parallel to the extension direction of the main channel. In practical applications, the second branch channel can be used to connect with the liquid collection chamber of the cleaning equipment. The suction can be transmitted from the main channel to the second branch channel without loss. The liquid dirt in the liquid collection chamber can directly enter the main channel through the second connection port without turning or obstruction, thus avoiding the liquid dirt remaining inside the housing.

[0054] In the channel switching component of this application, when the valve plate is in the first rotation angle, the valve plate is parallel to the extension direction of the main channel and closely abuts against the side wall of the main channel, effectively avoiding the valve plate from occupying the main channel and helping to increase the suction force inside the second branch channel. When applied to the cleaning base station, it can prevent the valve plate from blocking liquid dirt from being collected into the cleaning base station through the main channel, optimizing the liquid collection effect and improving the user experience.

[0055] In the channel switching component of this application, when the valve plate is in the second rotation angle, the valve plate is tilted relative to the extension direction of the main channel. The surface of the tilted valve plate can form an airflow guiding surface, guiding the airflow from the first branch channel into the interior of the main channel, avoiding suction loss. When applied to a cleaning base station, it can optimize the dust collection effect and improve the user experience.

[0056] In the channel switching assembly of this application, the diameter of the valve plate is larger than the diameter of the first connecting port and the diameter of the valve plate is larger than the inner diameter of the main channel. This can effectively seal the first connecting port and the second connecting port, ensure the positional accuracy of the valve plate, and prevent excessive movement of the valve plate.

[0057] The channel switching component of this application includes a position detection element for detecting the rotation angle of the valve plate. The position detection element includes a rocker arm and a limit switch. The rotational movement of the rocker arm is completely synchronized with the rotational movement of the valve plate. When the valve plate moves to the correct position, the rocker arm touches the sensing end of the corresponding limit switch and sends a feedback signal. This can prevent the valve plate from moving excessively, effectively ensure the positional accuracy of the valve plate, and prevent damage to the valve plate and the drive motor.

[0073] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0074] The integrated cleaning base station with dual fans is bulky, has redundant piping, and is costly. In addition, users need to maintain the filtration devices of two systems separately, which is costly and complex, and does not improve the user experience.

[0075] In single-fan base stations that use a duct switching structure to switch between dust collection and liquid collection functions, the duct switching structure often relies on spring force or manual operation, lacking precise limit and positioning mechanisms. During switching, positioning deviations are prone to occur, making it impossible to stably switch to the dust collection duct or liquid collection duct, and even causing jamming. Furthermore, the lack of effective limit protection can easily lead to excessive movement of the switching components, damaging the duct or motor. The switching process is not smooth and prone to damage, resulting in poor duct switching accuracy and stability. It is also impossible to guarantee the sealing performance after duct switching, leading to severe suction loss and affecting the self-cleaning effect.

[0076] To address the aforementioned issues, the applicant has developed a novel channel switching component. This component can be applied to cleaning base stations for duct switching, and it integrates dust collection and liquid collection functions with a single fan. It also ensures sealing performance after duct switching, avoiding suction loss. Furthermore, the duct switching accuracy and stability are excellent, and the switching process is smooth, which helps improve self-cleaning effect and optimize user experience.

[0077] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first working state of an embodiment of the channel switching component of this application. Figure 2 This is a cross-sectional structural diagram of the first working state of an embodiment of the channel switching component of this application.

[0078] like Figure 1 and Figure 2 As shown, the component includes a housing 100, and a main channel 101, a first branch channel 102, and a second branch channel 103 are formed inside the housing 100.

[0079] The main channel 101 has a first connection port 1011 and a second connection port 1012 that are respectively connected to the first branch channel 102 and the second branch channel 103, and the first connection port 1011 and the second connection port 1012 are arranged adjacent to each other.

[0080] A rotatable valve plate 200 is arranged inside the main channel 101. The valve plate 200 is located between the first connecting port 1011 and the second connecting port 1012. When the valve plate 200 is at a first rotation angle, the valve plate 200 abuts against the inner wall of one side of the main channel 101 to seal the first connecting port 1011. Figure 2 In the state shown, the first branch channel 102 is closed by the valve plate 200, and the main channel 101 is connected to the second branch channel 103; while when the valve plate 200 is at the second rotation angle, please refer to... Figure 3 , Figure 3 This is a cross-sectional structural diagram of the second working state of an embodiment of the channel switching component of this application, as shown below. Figure 3 As shown, the valve plate 200 abuts against the inner wall of the other side of the main channel 101 to seal the second communication port 1012. At this time, the second branch channel 103 is closed by the valve plate 200, and the main channel 101 is connected to the first branch channel 102.

[0081] like Figure 1 As shown, a drive unit 300 for driving the valve plate 200 to rotate is also arranged outside the housing 100. The drive unit 300 can control the valve plate 200 to switch positions between a first rotation angle and a second rotation angle, thereby controlling the main channel 101 to connect with the first branch channel 102 or with the second branch channel 103.

[0082] Based on the above solution, the air duct switching can be achieved by rotating the valve plate 200. The rotational movement is simple and direct, the power transmission path is short, which improves the response speed and reliability, and the switching process is smooth. The valve plate 200 abuts against the inner wall of the housing 100 at both the first and second rotation angles, which can ensure the overall sealing of the air duct and effectively avoid suction loss. When the valve plate 200 is rotated to the position, the valve plate 200 abuts against the inner wall of the housing 100 and is limited by the housing 100, which can ensure the accuracy and stability of the air duct switching.

[0083] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the first connection port 1011 is located on the channel side wall of the main channel 101, and the second connection port 1012 is located at the end of the main channel 101.

[0084] Based on the above scheme, the extension direction of the second branch channel 103 near the main channel 101 is parallel to the extension direction of the main channel 101. In practical applications, the second branch channel 103 can be used to connect with the liquid collection chamber of the cleaning equipment. When the main channel 101 is connected to the second branch channel 103, the suction can be transmitted from the main channel 101 to the second branch channel 103 without loss. The liquid dirt in the liquid collection chamber can directly enter the main channel 101 through the second connecting port 1012 without turning or obstruction, thus avoiding the liquid dirt remaining inside the housing 100.

[0085] Furthermore, such as Figure 2 As shown, in this embodiment, when the valve plate 200 is at the first rotation angle, the valve plate 200 is parallel to the extension direction of the main channel 101 and is in close contact with the side wall of the main channel 101.

[0086] Based on the above solution, the valve plate 200 can be effectively avoided from occupying the main channel 101, which helps to increase the suction force inside the second branch channel 103. When applied to the cleaning base station, the valve plate 200 can be prevented from blocking liquid dirt from being collected into the cleaning base station through the main channel 101, thus optimizing the liquid collection effect and improving the user experience.

[0087] Furthermore, such as Figure 3 As shown, in this embodiment, when the valve plate 200 is at the second rotation angle, the valve plate 200 is inclined to the extension direction of the main channel 101, and the valve plate 200 extends inclinedly to the side of the main channel 101 away from the first connecting port 1011 in the direction pointing to the first connecting port 1011.

[0088] Based on the above solution, the surface of the inclined valve plate 200 can form an airflow guiding surface, guiding the airflow from the first branch channel 102 into the interior of the main channel 101, avoiding suction loss. When applied to a cleaning base station, it can optimize the dust collection effect and improve the user experience.

[0089] Furthermore, such as Figure 2 As shown, in this embodiment, the diameter of the valve plate 200 is larger than the diameter of the first communication port 1011. When the valve plate 200 is at the first rotation angle, the outer periphery of the valve plate 200 can abut against the inner wall of the main channel 101.

[0090] Based on the above solution, the first connecting port 1011 can be effectively sealed. At the same time, the interference between the outer periphery of the plate and the inner wall of the main channel 101 can also ensure the positional accuracy of the valve plate 200 and prevent excessive movement of the valve plate 200.

[0091] Furthermore, such as Figure 3 As shown, in this embodiment, the diameter of the valve plate 200 is larger than the inner diameter of the main channel 101. When the valve plate 200 is at the second rotation angle, the outer peripheral surface of the valve plate 200 abuts against the inner wall of the main channel 101.

[0092] Based on the above scheme, the second communication port 1012 can be effectively sealed by the outer peripheral surface of the valve plate 200 abutting against the inner wall of the main channel 101. At the same time, the diameter of the valve plate 200 is larger than the inner diameter of the main channel 101, so that when the valve plate 200 moves to the second rotation angle, the valve plate 200 is tilted relative to the extension direction of the main channel 101, which helps to guide the airflow. In addition, the interference between the outer peripheral surface of the valve plate 200 and the inner wall of the main channel 101 can ensure the positional accuracy of the valve plate 200 and avoid excessive movement of the valve plate 200.

[0093] Furthermore, such as Figure 2 and Figure 3As shown, in this embodiment, the extension direction of the first branch channel 102 near the end of the main channel 101 is perpendicular to the extension direction of the main channel 101; in other embodiments, the extension direction of the first branch channel 102 near the end of the main channel 101 may not be perpendicular to the extension direction of the main channel 101. It can be designed based on the actual structural requirements of the clean base station, and all of them can achieve the effect of this embodiment.

[0094] Furthermore, such as Figure 2 and Figure 3 As shown, in this embodiment, the valve plate 200 includes a main body 202 and a flexible sealing part 203 located around the main body 202. When the valve plate 200 is at the first rotation angle and the second rotation angle, the flexible sealing part 203 can deform against the inner wall of the main channel 101, further optimizing the overall sealing performance of the air duct.

[0095] Specifically, in one embodiment, the flexible sealing part 203 can be made of silicone material and molded with high precision so that it can fit tightly against the inner wall of the housing 100. By utilizing the elastic recovery and low compression deformation characteristics of silicone material, the air duct is sealed to prevent suction leakage.

[0096] The structure of the drive unit 300 is described in detail below. Please refer to [link / reference]. Figure 4 , Figure 4 yes Figure 2 A schematic diagram of the cross-sectional structure of the middle AA surface.

[0097] like Figure 4 As shown, the drive unit 300 includes a rotating column 301 and a drive motor 302. One end of the rotating column 301 is inserted into the housing 100 and connected to the valve plate 200, while the other end extends out of the housing 100. The drive motor 302 is arranged outside the housing 100 and is used to drive the rotating column 301 to rotate.

[0098] Based on the above scheme, the output end of the drive motor 302 is linked to the rotating column 301. By controlling the operation of the drive motor 302, the rotating column 301 can be controlled to rotate, thereby driving the valve plate 200 to rotate synchronously. The position is switched between the first rotation angle and the second rotation angle to realize the switching of the air duct connected to the main air duct.

[0099] For further details, please refer to Figure 5 , Figure 5 This is a schematic diagram of one embodiment of the driver component of this application. Figure 5 As shown, in this embodiment, a reduction gear 303 is arranged at the output end of the drive motor 302. The reduction gear 303 meshes with the tooth surface 3011 at the end of the rotating column 301, thereby realizing the rotation control of the rotating column 301.

[0100] Based on the above solution, the output speed of the drive motor 302 can be reduced, while the torque of the drive valve plate 200 can be significantly increased, thereby achieving more precise and stable motion control.

[0101] In other embodiments, the output end of the drive motor 302 can also be directly connected to the rotating column 301, or the rotating column 301 can be driven by a structural connection.

[0102] Furthermore, such as Figure 4 As shown, in this embodiment, one end of the valve plate 200 is provided with an opening 201 extending along its rotation axis. The rotating column 301 is inserted into one end of the opening 201 and is circumferentially limited with the valve plate 200 to realize the connection between the rotating column 301 and the valve plate 200.

[0103] Based on the above solution, it is convenient to install and disassemble the rotating column 301 and the valve plate 200, and to facilitate user maintenance of the valve plate 200.

[0104] In other embodiments, the rotating column 301 can also be directly fixed to the valve plate 200, which can also realize the rotation drive of the valve plate 200.

[0105] Furthermore, in this embodiment, the opening 201 extends from one end of the valve plate 200 to the other end, and the channel switching assembly also includes a guide post 304 extending along the rotation axis of the valve plate 200. One end of the guide post 304 is connected to the housing 100, and the other end is inserted into the other end of the opening 201.

[0106] Based on the above scheme, the guide post 304 can limit and guide the rotational movement of the valve plate 200, ensuring that the valve plate 200 can only reciprocate around the axis of the rotating post 301, avoiding deviation or jamming during rotation, ensuring smooth swing of the valve plate 200, and reducing wear on the rotating post 301, thus extending the service life of the component.

[0107] In this embodiment, the guide post 304 is inserted into one end of the opening 201, allowing the valve plate 200 to rotate around the guide post 304. The end of the opening 201 near the guide post 304 can be a circular hole, and correspondingly, the guide post 304 can be a matching cylindrical structure. The rotating post 301 is inserted into the other end of the opening 201 and is positioned relative to the valve plate 200 in the circumferential direction. The end of the opening 201 near the rotating post 301 can be a non-circular hole, such as a rectangle, polygon, irregular shape, etc. Correspondingly, the rotating post 301 can be a matching cylindrical structure with a non-circular cross-section, so as to achieve the purpose of the rotating post 301 driving the valve plate 200 to rotate around the guide post 304.

[0108] In other embodiments, the shapes of the two ends of the opening 201 can also be the same. The rotating column 301 can be interference-fitted with the inner wall of the opening 201, or the rotating column 301 can be fixed to the inner wall of the opening 201 by adhesive or the like. The guide column 304 can form a rotation gap with the inner wall of the opening 201, which can also achieve the purpose of the rotating column 301 driving the valve plate 200 to rotate around the guide column 304.

[0109] Furthermore, such as Figure 5 As shown, in this embodiment, the drive unit 300 also includes a position detection unit 305 for detecting the rotation angle of the valve plate 200. The position detection unit 305 is connected to the drive motor 302 by signal, which further improves the accuracy and stability of the air duct switching.

[0110] Specifically, the position detection component 305 includes a rocker arm 3051 and a limit switch 3052. The rocker arm 3051 is arranged outside the housing 100 and is sleeved on the rotating column 301 and is circumferentially limited with the rotating column 301. The limit switch 3052 is arranged outside the housing 100 and is signal connected to the drive motor 302.

[0111] Understandably, the rocker arm 3051 and the rotating column 301 are circumferentially limited. When the rotating column 301 rotates and drives the valve plate 200 to rotate, it can control the rocker arm 3051 to rotate synchronously. The rotational movement of the rocker arm 3051 is completely synchronized with the rotational movement of the valve plate 200. Since the valve plate 200 rotates between the first rotation angle and the second rotation angle, the limit displacement position of the rocker arm 3051 is fixed.

[0112] The limit switch 3052 can be arranged at the extreme displacement position of the rocker arm 3051. When the valve plate 200 moves to the first rotation angle, the rocker arm 3051 touches the sensing segment of the limit switch 3052 on the corresponding side. In response to the sensing signal of the limit switch 3052, the drive motor 302 can stop working. When the valve plate 200 moves to the second rotation angle, the rocker arm 3051 touches the sensing end of the limit switch 3052 on the other side. In response to the sensing signal of the limit switch 3052, the drive motor 302 can stop working.

[0113] Based on the above solution, excessive movement of the valve plate 200 can be avoided, the positional accuracy of the valve plate 200 can be effectively guaranteed, and damage to the valve plate 200 and the drive motor 302 can be avoided.

[0114] In other embodiments, the position detection element 305 may also be other commonly used sensing elements in the art, such as photoelectric sensors, or the position detection element 305 may not be arranged outside the housing 100. For example, the position detection element 305 may also be arranged on the inner wall of the housing 100 and used to directly detect the position of the valve plate 200. Correspondingly, the rocker arm 3051 may also be omitted, etc., all of which can achieve the effect of this embodiment.

[0115] In the above embodiments, the valve plate 200 is rotated by driving motor 302. In other embodiments, the valve plate 200 can also be rotated by other means. For example, the valve plate 200 can be partially or entirely made of ferromagnetic material, and an electromagnetic coil can be arranged inside the housing 100. The rotation control of the valve plate 200 can be achieved by using the magnetic attraction force generated when the electromagnetic coil is energized. All of these can achieve the effect of this embodiment.

[0116] Based on the channel switching components described above, the overall sealing after duct switching can be guaranteed, effectively avoiding suction loss. The valve plate 200 has simple and efficient movement, fast response speed, high reliability, and smooth duct switching process. When applied to clean base stations, it helps to optimize the self-cleaning performance of the base station and improve the user experience.

[0117] This application also provides a clean base station; please refer to [link / reference]. Figure 6 , Figure 6 This is a schematic diagram of one embodiment of the clean base station of this application.

[0118] The cleaning base station is used for cleaning equipment, which includes a first cleaning accessory with a dust collection chamber and a second cleaning accessory with a liquid collection chamber.

[0119] like Figure 6 As shown, the clean base station includes a channel switching component according to any of the above embodiments, as well as a first pipe 400, a second pipe 500, and a fan 600.

[0120] The first pipe 400 has one end connected to the first branch channel 102 and the other end connected to the dust collection chamber; the second pipe 500 has one end connected to the second branch channel 103 and the other end connected to the liquid collection chamber; the working end of the fan 600 is connected to the main channel 101.

[0121] When the cleaning base station is connected to the cleaning equipment, the first pipe 400 is connected to the dust collection chamber of the cleaning equipment, and the second pipe 500 is connected to the liquid collection chamber of the cleaning equipment.

[0122] When the cleaning base station and the cleaning equipment are docked, the valve plate 200 is switched to the first rotation angle, the main channel 101 is connected to the second branch channel 103, and the liquid collection chamber is connected to the working end of the fan 600 through the second pipe 500, the second branch pipe and the main channel 101. The negative pressure generated when the fan 600 is working can collect the dirt in the liquid collection chamber through the pipe to the inside of the cleaning base station, thus realizing the liquid collection function.

[0123] With the cleaning base station and cleaning equipment in a docked state, the valve plate 200 is switched to the second rotation angle, the main channel 101 is connected to the first branch channel 102, and the dust collection chamber is connected to the working end of the fan 600 through the first pipe 400, the first branch pipe and the main channel 101. The negative pressure generated when the fan 600 is working can collect the dirt in the dust collection chamber through the pipe to the inside of the cleaning base station, thus realizing the dust collection function.

[0124] The clean base station based on the above embodiments can handle both dry and wet waste with a single fan 600, which effectively simplifies the base station structure, facilitates the miniaturization of the base station design, reduces the number of times users need to maintain the equipment, simplifies the user maintenance process, and helps improve the user experience.

[0125] This application also provides a cleaning system, which includes a cleaning base station according to any of the above embodiments and a cleaning device adapted to the cleaning base station. The cleaning device includes a first cleaning attachment and a second cleaning attachment. The first cleaning attachment has a dust collection chamber and the second cleaning attachment has a liquid collection chamber.

[0126] In this embodiment, the first cleaning accessory is a vacuum cleaner handheld part with a built-in dust cup, and the second cleaning accessory can be a floor scrubbing brush with a built-in water tank. In other embodiments, the first cleaning accessory can also be other accessories with a built-in dust collection chamber, and the second cleaning accessory can also be other accessories with a built-in liquid collection chamber, all of which can achieve the effect of this embodiment.

[0127] In this embodiment, the cleaning equipment is a cleaning equipment that combines floor washing and vacuuming functions. The floor washing and vacuuming functions can be switched by changing the accessories. In other embodiments, the cleaning equipment may also include a separate vacuum cleaner and a separate floor scrubber, both of which can achieve the effect of this embodiment.

[0128] This application also provides a self-cleaning method, which is applied to the cleaning system of any of the above embodiments. Please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a flowchart illustrating one embodiment of the self-cleaning method of this application.

[0129] like Figure 7 As shown, the self-cleaning method includes:

[0130] S101. When the cleaning equipment is connected to the cleaning base station, determine whether the second cleaning accessory is in place.

[0131] In this embodiment, the second cleaning attachment of the cleaning equipment is designed to be replaceable. When the second cleaning attachment is installed on the cleaning equipment, the cleaning equipment can perform a floor washing operation and collect the dirty liquid generated during the floor washing into the liquid collection chamber of the second cleaning attachment. When the second cleaning attachment is removed, the cleaning equipment can be equipped with a floor sweeping brush to perform a vacuuming operation and collect the dirty liquid generated during the vacuuming into the dust collection chamber of the first cleaning attachment through the internal pipes of the cleaning equipment.

[0132] Therefore, before performing self-cleaning operations, it can be determined whether the second cleaning attachment is in place, so as to decide whether to perform dust collection or liquid collection operations during subsequent self-cleaning.

[0133] In one embodiment, a presence detection switch can be configured on the cleaning base station to detect whether the second cleaning accessory is in place. When the presence detection switch detects the second cleaning accessory, it can be determined that the second cleaning accessory is in place; otherwise, it can be determined that the second cleaning accessory is not in place.

[0134] In another embodiment, a sensor can be provided on the second cleaning accessory, and a matching sensor can be provided on the cleaning base station to identify whether the second cleaning accessory is in place. For example, the sensor and the matching sensor can be RFID tags and card readers, etc., all of which can achieve the effects of this embodiment.

[0135] In one implementation, after determining the presence of the second cleaning device based on the methods described above, a secondary verification can be performed. Specifically, the cleaning base station controller can switch to slave mode, and the cleaning accessory controller can act as a master to communicate with the slave. The master can send a broadcast identification command, and when the slave receives the identification command, it can reply with the command. Both parties determine the type of the currently accessed accessory by verifying the agreed command format, complete the identity confirmation, and realize the secondary verification of the accessory type. The cleaning base station only activates the currently accessed cleaning accessory and performs operations such as adding water, draining water, and starting the corresponding pipeline valves, effectively preventing misoperation.

[0136] For example, when the presence of the second cleaning accessory is confirmed by the presence detection switch, the base station MCU can switch to slave mode. The second cleaning accessory, acting as the master, can send a broadcast identification command every 200ms via the UART port. After receiving the command, the base station slave will reply within 500ms. By verifying the agreed command format, secondary verification of the accessory type is achieved.

[0137] When the second cleaning attachment is not in place, the methods include:

[0138] S102a, In response to the self-cleaning command, the valve plate is controlled to rotate in the first direction to the second rotation angle by the drive component.

[0139] When the second cleaning attachment is not in place, the system performs a dust collection operation, controlling the valve plate to rotate in the first direction to the second rotation angle through the drive component. At this time, the working end of the fan is connected to the dust collection chamber of the first cleaning attachment through the main channel, the first branch channel, and the first pipe.

[0140] In one implementation, the valve plate can be determined to be in position by detecting the signal fed back from the limit switch of the channel switching component. Specifically, the valve plate can be controlled to rotate in the first direction by the drive until the signal fed back from the limit switch is received. At this time, the valve plate moves to the second rotation angle, and the drive can be controlled to stop working to ensure the positional accuracy of the valve plate.

[0141] S103a: Control the operation of the fan to collect the contaminants in the collection chamber through the second pipe to the cleaning base station.

[0142] When the valve plate is switched to the second rotation angle, the dust collection chamber is connected to the working end of the fan, which can control the fan to generate negative pressure, sucking the solid dirt in the dust collection chamber into the cleaning base station to complete the dust collection operation.

[0143] S104a After the dirt in the dust collection chamber is collected, the valve plate is controlled by the drive component to rotate in the second direction to the first rotation angle.

[0144] The second direction is opposite to the first direction.

[0145] In one embodiment, after the dust collection operation is completed, the valve plate can be controlled to return to the first rotation angle so as to maintain the main channel and the second channel in communication when self-cleaning is not performed, so that liquid collection can be performed directly when the second cleaning accessory is in place.

[0146] When the second cleaning attachment is in place, the method includes:

[0147] S102b, in response to the self-cleaning command, controls the valve plate to rotate in the second direction to the first rotation angle via the drive component.

[0148] When the second cleaning attachment is in place, the system first performs a liquid collection operation, controlling the valve plate to rotate to the first rotation angle in the second direction through the drive component. At this time, the working end of the blower is connected to the liquid collection chamber of the second cleaning attachment through the main channel, the second branch channel, and the second pipe.

[0149] In one implementation, similar to S102a, the valve plate can be determined to be in position by detecting the signal fed back by the limit switch of the channel switching component. The specific method will not be described in detail.

[0150] S103b: Control the fan to operate so that the dirt in the collection chamber is collected into the cleaning base station through the second pipe.

[0151] When the valve plate is switched to the first rotation angle, the liquid collection chamber is connected to the working end of the fan, which can control the fan to generate negative pressure, sucking the liquid dirt in the liquid collection chamber into the cleaning base station, thus completing the liquid collection operation.

[0152] S104b After the dirt in the collection chamber is collected, the valve plate is controlled to rotate in the first direction to the second rotation angle by the drive component.

[0153] In one embodiment, after the liquid collection operation is completed, the system can continue to perform the dust collection operation by rotating the valve plate to the second rotation angle to connect the main channel, the first branch channel, the first channel and the dust collection chamber.

[0154] S105b: Control the fan to operate so that the dirt in the dust collection chamber is collected into the cleaning station through the first pipe.

[0155] Similar to S103a, when the working end of the fan is connected to the dust collection chamber, the fan can be controlled to generate negative pressure, which will draw solid dirt in the dust collection chamber into the cleaning base station to complete the dust collection operation.

[0156] Based on the self-cleaning methods described above, the cleaning base station can automatically process wet and dry waste, simplifying user operations and helping to improve the user experience.
