Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and more particularly to a cleaning device and cleaning system. Background Technology

[0002] In related technologies, a cleaning system may include a cleaning base station and a cleaning device. The cleaning base station can charge the cleaning device and perform self-dust collection. The cleaning device includes a main unit and a dust cup. The main unit can provide negative pressure suction so that when the cleaning device is working, it can suck the debris on the surface to be cleaned into the dust cup. When the cleaning device is connected to the cleaning base station, the dust cup lid is opened, and then the debris in the dust cup is cleaned by the self-dust collection function of the cleaning base station.

[0003] However, cleaning stations also require a separate fan, which leads to higher costs for the cleaning system. Utility Model Content

[0004] Based on this, embodiments of this application provide a cleaning device and a cleaning system to address the shortcomings of related technologies.

[0005] In a first aspect, embodiments of this application provide a cleaning device, which includes a housing, a fan assembly, a dust cup assembly, and an air duct switching assembly, wherein the fan assembly and the dust cup assembly are both connected to the housing;

[0006] The air duct switching assembly includes an air duct component and a switching component. The air duct component has an interconnected air duct, a first air inlet, a second air inlet, and a first air outlet. The first air inlet is connected to the dust cup assembly, the second air inlet is configured to connect to the cleaning base station, and the first air outlet is connected to the fan assembly.

[0007] The switching element is moved along the first direction and disposed in the air duct to switch between the first working position and the second working position. When the switching element is in the first working position, the first air inlet, the first air outlet and the fan assembly are connected in sequence. When the switching element is in the second working position, the second air inlet, the first air outlet and the fan assembly are connected in sequence.

[0008] The cleaning device provided in this application embodiment has a housing for mounting a fan assembly, a dust cup assembly, and an air duct switching assembly. The fan assembly provides negative pressure suction, the dust cup assembly collects dirt from the surface to be cleaned, a first air inlet connects the air duct and the dust cup assembly, a second air inlet connects the air duct and the cleaning base station, and a first air outlet connects the air duct and the fan assembly. A switching element is provided and reciprocates along a first direction, allowing the switching element to be in a first working position, thus connecting the fan assembly and the dust cup assembly, enabling the fan assembly to provide negative pressure suction to the dust cup assembly. Alternatively, the switching element can be in a second working position, connecting the fan assembly and the cleaning base station, enabling the fan assembly to provide negative pressure suction to the cleaning base station. Thus, the cleaning base station and the cleaning device can share a single fan assembly, reducing the cost of the cleaning system.

[0009] In one possible implementation, the duct switching assembly further includes a transmission unit connected to the switching element, and the transmission unit is configured to drive the switching element from a first working position to a second working position under the action of an external force.

[0010] Thus, when the cleaning equipment is connected to the cleaning base station, the external force applied to the transmission unit by the cleaning base station or by hand can drive the switching component to move from the first working position to the second working position, thereby blocking the switching component between the first air inlet and the first air outlet, and causing the fluid to flow sequentially along the dust cup assembly, the cleaning base station, the second air inlet, the first air outlet and the fan assembly, thereby enabling the fan assembly to provide negative pressure suction to the cleaning base station.

[0011] In one possible implementation, the transmission unit includes a guide shaft extending in a first direction, with a first end of the guide shaft located outside the air duct and a second end of the guide shaft inserted into the air duct and connected to the switching element.

[0012] Thus, when an external force drives the guide shaft to move along its own axial direction, the guide shaft can drive the switching component to reciprocate along the first direction, thereby enabling the switching component to flexibly switch between the first working position and the second working position to meet different cleaning needs.

[0013] In one possible implementation, the transmission unit further includes a linkage, the first end of which is connected to the first end of the guide shaft, and the second end of which is configured to abut against the clean base station.

[0014] Thus, when the cleaning equipment connects to the cleaning base station, the cleaning base station can abut against the connecting rod, thereby applying force to the connecting rod, which in turn drives the connecting rod to move. The connecting rod drives the guide shaft to move along the first direction, thereby causing the switching component to move along the first direction to the second working position, so that the fan assembly can provide negative pressure suction to the cleaning base station.

[0015] In one possible implementation, the duct switching assembly further includes a reset unit connected to the housing and configured to drive the switching element to move from the second working position to the first working position.

[0016] Thus, when the cleaning equipment disconnects from the cleaning base station, the force exerted by the cleaning base station on the linkage disappears, and the reset unit can drive the switching component to move along the first direction, thereby resetting the switching component from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0017] In one possible implementation, the reset unit includes at least one of a first elastic element and a second elastic element, one end of the first elastic element in the direction of elastic force is connected to the housing, the other end of the first elastic element in the direction of elastic force is connected to the guide shaft, and the elastic force of the first elastic element points from the first working position to the second working position.

[0018] One end of the second elastic element in the direction of elastic force is connected to the housing, and the other end of the second elastic element in the direction of elastic force is connected to the connecting rod. The elastic force of the second elastic element points from the first working position to the second working position.

[0019] In this way, when the cleaning equipment is disconnected from the cleaning base station, the elastic force of the first elastic element can drive the guide shaft to move along the first direction, and the elastic force of the second elastic element can drive the linkage to move, thereby driving the guide shaft to move along the first direction, and thus driving the switching component to reset from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0020] In one possible implementation, the first air inlet and the second air inlet are located at opposite ends of the duct, and the first air outlet is located between the two ends of the duct.

[0021] Thus, when the switching component moves along the first direction to the side of the first air outlet near the first air inlet, and the switching component is located at any position between the first air inlet and the first air outlet, the first air inlet and the first air outlet can be disconnected. When the switching component moves along the first direction to the side of the first air outlet near the second air inlet, and the switching component is located at any position between the second air inlet and the first air outlet, the second air inlet and the first air outlet can be disconnected, thereby enabling the switching between the first working position and the second working position through the linear movement of the switching component.

[0022] In one possible implementation, the air duct includes a first air duct section and a second air duct section connected in sequence. Both the first air duct section and the second air duct section extend along a first direction. The end of the first air duct section away from the second air duct section forms a first air inlet.

[0023] The first air outlet is located between the two ends of the second air duct section, and the switching component moves back and forth between the two ends of the second air duct section.

[0024] Thus, when the switching component moves along the first direction to the end of the second air duct section near the first air duct section, the first air duct section and the second air duct section can be disconnected, thereby disconnecting the first air inlet and the first air outlet, so that the dust cup assembly, the cleaning base station, the second air inlet, the first air outlet and the fan assembly are connected in sequence.

[0025] In one possible implementation, a first limiting part is provided at the end of the second air duct section away from the first air duct section, and when the switching member is in the first working position, the switching member abuts against the first limiting part.

[0026] The second air duct section is provided with a second limiting part at one end near the first air duct section. When the switching component is in the second working position, the switching component abuts against the second limiting part.

[0027] Thus, when the switching component moves along the first direction to abut against the first limiting part, it indicates that the switching component is in the first working position. When the switching component moves along the first direction to abut against the second limiting part, it indicates that the switching component is in the second working position. This helps to control the movement stroke of the switching component and improve the working reliability of the switching component.

[0028] In one possible implementation, the air duct also includes a third air duct section, with the first, second, and third air duct sections connected in sequence, and the end of the third air duct section facing away from the second air duct section forming a second air inlet.

[0029] Thus, when the switching component moves along the first direction to the end of the second air duct section near the third air duct section, the second air duct section and the third air duct can be disconnected, and the first air duct section and the second air duct section can be connected. This disconnects the second air inlet and the first air outlet, and connects the first air inlet and the first air outlet, thereby connecting the dust cup assembly, the first air inlet, the first air outlet and the fan assembly in sequence.

[0030] In one possible implementation, the guide shaft includes a first shaft segment and a second shaft segment connected in sequence, wherein the diameter of the first shaft segment is larger than the diameter of the second shaft segment;

[0031] The switching component is connected to the end of the second shaft section near the first shaft section.

[0032] Thus, the end face of the first shaft segment near the second shaft segment can restrict the position of the switching component, thereby fixing the switching component at the end of the second shaft segment near the first shaft segment, so that the guide shaft drives the switching component to move together in the first direction.

[0033] In one possible implementation, the duct switching assembly further includes a connector, wherein the second shaft segment has an external thread at one end near the first shaft segment, and the connector has an internal thread that matches the external thread, so that the connector is threadedly connected to the second shaft segment, and the switching member abuts against the end face of the first shaft segment near the second shaft segment and the connector.

[0034] Thus, after the connector is threadedly connected to the second shaft segment, the switching component can be fixed between the end face of the first shaft segment near the second shaft segment and the connector, thereby fixing the switching component to the guide shaft, so that the switching component can move synchronously with the guide shaft.

[0035] In one possible implementation, the duct component has a through hole that communicates with the duct, one end of the first shaft segment facing away from the second shaft segment is located outside the duct, and the other end of the first shaft segment near the second shaft segment is inserted into the duct through the through hole.

[0036] In this way, the guide shaft can be inserted into the air duct through the through hole, so that the guide shaft can drive the switching component to move within the air duct. Furthermore, the end of the first shaft segment facing away from the second shaft segment can be connected to the first elastic element, so that after the cleaning equipment is disconnected from the cleaning base station, the elastic force of the first elastic element can drive the first shaft segment to move towards the second shaft segment, thereby causing the switching component to reset from the second working position to the first working position.

[0037] In one possible implementation, there is a transition fit between the second shaft segment and the through hole.

[0038] In this way, the second shaft segment can move relative to the through hole in the first direction, thereby causing the guide shaft to drive the switching element to move in the first direction, and improving the sealing between the second shaft segment and the through hole to reduce airflow leakage.

[0039] In one possible implementation, the switching element includes an interconnected body and a sealing part, the sealing part being sealed to the inner wall of the duct.

[0040] Thus, the guide shaft can be connected to the main body to drive the switching component to move along the first direction. When the switching component moves to the first working position or the second working position, the sealing part can abut against the inner wall of the air duct to seal the gap between the switching component and the air duct, so as to prevent airflow from leaking from the gap between the switching component and the air duct, thereby improving the suction of the cleaning equipment or cleaning base station.

[0041] In one possible implementation, the sealing portion includes at least one of a first sealing portion and a second sealing portion, wherein the first sealing portion is located on the outer peripheral side of the body, and the second sealing portion is located on at least one side of the body along a first direction.

[0042] Thus, the first sealing part can be arranged around the outer periphery of the body to form a sealed connection between the outer periphery of the body and the inner wall of the air duct, and the second sealing part can be arranged on one or both sides of the body in the first direction to form a sealed connection between the two sides of the body and the inner wall of the air duct.

[0043] Secondly, embodiments of this application also provide a cleaning system, including a cleaning base station and the cleaning equipment provided in the first aspect, wherein the cleaning base station is configured to automatically collect dust from the cleaning equipment.

[0044] In one possible implementation, when the cleaning equipment docks with the cleaning base station, the switching component moves from the first working position to the second working position;

[0045] When the cleaning equipment disconnects from the cleaning base station, the switching unit moves from the second working position to the first working position.

[0046] In this way, automatic switching of the switching components can be achieved without manual switching.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0063] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0064] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0065] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0066] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0067] In related technologies, a cleaning system may include a cleaning base station and a cleaning device. The cleaning base station can charge the cleaning device and perform self-dust collection. The cleaning device includes a main unit and a dust cup. The main unit can provide negative pressure suction so that when the cleaning device is working, it can suck the debris on the surface to be cleaned into the dust cup. When the cleaning device is connected to the cleaning base station, the dust cup lid is opened, and then the debris in the dust cup is cleaned by the self-dust collection function of the cleaning base station.

[0068] However, cleaning stations also require a separate fan, which leads to higher costs for the cleaning system.

[0069] In view of this, embodiments of this application provide a cleaning device and a cleaning system. By setting an air duct switching component on the cleaning device, the movement of the switching component controls the fan component to provide negative pressure suction to one of the dust cup component and the cleaning base station, so that the cleaning system can collect dust by means of the fan component of the cleaning device, thereby reducing the cost of the cleaning system.

[0070] The specific implementation methods of the cleaning equipment and cleaning system provided in this application will be described in detail below with reference to the accompanying drawings.

[0071] Reference Figure 1 As shown in the illustration, this application provides a cleaning system, which includes a cleaning base station and cleaning equipment. The cleaning base station can be used to collect dust from the cleaning equipment. Alternatively, the cleaning base station can also be used to charge the cleaning equipment, etc.

[0072] For example, the cleaning equipment can be a vacuum cleaner, a floor scrubber, etc., and the embodiments of this application do not limit this.

[0073] In this embodiment, the cleaning device can be used in conjunction with a cleaning base station so that the cleaning base station can charge the cleaning device or collect dust on its own. Alternatively, the cleaning device can be used independently so that it can vacuum the surface to be cleaned.

[0074] When used alone, the cleaning equipment provides negative pressure suction to remove dirt from the surface. When users need to clean the equipment, it can be used in conjunction with a cleaning base station, allowing the base station to utilize the negative pressure suction to assist in recovering dirt from the cleaning equipment.

[0075] Reference Figures 1 to 6 As shown, based on the above embodiments, this application also provides a cleaning device, which includes a housing 100, a fan assembly 200, a dust cup assembly 300, and an air duct switching assembly 400. The fan assembly 200 and the dust cup assembly 300 are both connected to the housing 100.

[0076] The air duct switching assembly 400 includes an air duct component 410 and a switching component 420. The air duct component 410 has an interconnected air duct 411, a first air inlet 412, a second air inlet 413, and a first air outlet 414. The first air inlet 412 is connected to the dust cup assembly 300, the second air inlet 413 is configured to be connected to the cleaning base station, and the first air outlet 414 is connected to the fan assembly 200.

[0077] The switching element 420 is movable along the first direction and disposed in the air duct 411 to switch between the first working position and the second working position. When the switching element 420 is in the first working position, the first air inlet 412, the first air outlet 414 and the fan assembly 200 are connected in sequence. When the switching element 420 is in the second working position, the second air inlet 413, the first air outlet 414 and the fan assembly 200 are connected in sequence.

[0078] In this embodiment, the housing 100 is used to install the fan assembly 200, the dust cup assembly 300, and the air duct switching assembly 400, thereby integrating the housing 100, the fan assembly 200, the dust cup assembly 300, and the air duct switching assembly 400 into a cleaning device. The fan assembly 200 is used to provide negative pressure suction for the cleaning device or cleaning base station.

[0079] When the fan assembly 200 provides negative pressure suction to the cleaning equipment, it can suck away dirt from the surface to be cleaned and collect it in the dust cup assembly 300. When the fan assembly 200 provides negative pressure suction to the cleaning base station, it can draw dirt from the dust cup assembly 300 into the cleaning base station, thereby realizing the self-dust collection function of the cleaning base station for the cleaning equipment.

[0080] Specifically, the air duct switching component 400 includes an air duct component 410, within which an air duct 411 is defined. The air duct 411 allows fluid to flow and changes its flow direction to form different airflow paths. The air duct 411 has a first air inlet 412, a second air inlet 413, and a first air outlet 414. When fluid flows sequentially along the first air inlet 412, the first air outlet 414, and the fan assembly 200, it forms the airflow path for the cleaning equipment during dust extraction. When fluid flows sequentially along the second air inlet 413, the first air outlet 414, and the fan assembly 200, it forms the airflow path for the cleaning base station during self-dust collection.

[0081] In order to form different airflow paths, the air duct switching assembly 400 also includes a switching element 420. The switching element 420 can be movably disposed in the air duct 411, and the switching element 420 can move linearly relative to the air duct element 410 in the first direction. In this way, the switching element 420 can have two working positions in the first direction, namely the first working position and the second working position.

[0082] Reference Figures 4 to 6 As shown, Figure 4 and Figure 6 This indicates that the switching unit 420 is in the first working position. Figure 5This illustrates the state of the switching element 420 in the second working position. When the switching element 420 moves to the first working position along the first direction, it can block the second air inlet 413 and the first air outlet 414, and connect the first air inlet 412 and the first air outlet 414. This allows the first air inlet 412, the first air outlet 414, and the fan assembly 200 to be connected in sequence, forming a dust-collecting airflow channel. The fluid then flows sequentially along the dust cup assembly 300, the first air inlet 412, the first air outlet 414, and the fan assembly 200, thereby using the negative pressure suction provided by the fan assembly 200 to remove dirt from the surface to be cleaned and collect it in the dust cup assembly 300.

[0083] When the switching component 420 moves to the second working position along the first direction, the switching component 420 can block the first air inlet 412 and the first air outlet 414, and make the second air inlet 413 and the first air outlet 414 connected. This allows the second air inlet 413, the first air outlet 414 and the fan assembly 200 to be connected in sequence, thereby forming an airflow channel for self-dust collection. This allows the fluid to flow sequentially along the dust cup assembly 300, the cleaning base station, the first air inlet 412, the first air outlet 414 and the fan assembly 200, thereby sucking away the dirt in the dust cup assembly 300 through the negative pressure suction provided by the fan assembly 200 and collecting it into the dust collection bag of the cleaning base station.

[0084] In this way, since the air duct 411 is equipped with a switching component 420, the cleaning equipment can be flexibly switched between two working modes. Furthermore, the cleaning base station can use the fan assembly 200 of the cleaning equipment, and the cleaning base station does not need to set up the fan assembly 200 separately, thereby reducing the cost of the cleaning system.

[0085] It should be noted that the first direction can be the height direction of the dust cup assembly 300, specifically referring to the X direction in the attached diagram.

[0086] The cleaning device provided in this embodiment includes a housing 100, a fan assembly 200, a dust cup assembly 300, and an air duct switching assembly 400. The air duct switching assembly 400 includes an air duct component 410 and a switching component 420. The air duct component 410 includes an air duct 411, a first air inlet 412, a second air inlet 413, and a first air outlet 414. The housing 100 is used to install the fan assembly 200, the dust cup assembly 300, and the air duct switching assembly 400. The fan assembly 200 provides negative pressure suction. The dust cup assembly 300 collects dirt from the surface to be cleaned. The first air inlet 412 connects the air duct 411 and the dust cup assembly 300. The second air inlet 413 connects the air duct 411 and the cleaning base station. The first air outlet 414 connects the air duct 411 and the fan assembly 200. By configuring a switching element 420 and reciprocating it in a first direction, the switching element 420 can be positioned in a first working position, thereby establishing communication between the fan assembly 200 and the dust cup assembly 300. This allows the fan assembly 200 to provide negative pressure suction to the dust cup assembly 300. Alternatively, the switching element 420 can be positioned in a second working position, establishing communication between the fan assembly 200 and the cleaning base station, allowing the fan assembly 200 to provide negative pressure suction to the cleaning base station. In this way, the cleaning base station and the cleaning equipment can share a single fan assembly 200, reducing the cost of the cleaning system.

[0087] Reference Figure 2 , Figure 3 As shown, in one possible implementation, the air duct switching assembly 400 further includes a transmission unit 430, which is connected to the switching member 420, and the transmission unit 430 is configured to drive the switching member 420 from a first working position to a second working position under the action of an external force.

[0088] Thus, when the cleaning equipment is connected to the cleaning base station, the external force applied by the cleaning base station to the transmission unit 430 can drive the switching component 420 to move from the first working position to the second working position, thereby blocking the switching component 420 between the first air inlet 412 and the first air outlet 414, thereby causing the fluid to flow sequentially along the dust cup assembly 300, the cleaning base station, the second air inlet 413, the first air outlet 414 and the fan assembly 200, thereby enabling the fan assembly 200 to provide negative pressure suction to the cleaning base station.

[0089] Alternatively, when external force from the hand is applied to the switching component 420, it can be moved along the first direction to move from the first working position to the second working position, thereby blocking the switching component 420 between the first air inlet 412 and the first air outlet 414, thereby connecting the dust cup assembly 300, the cleaning base station, the second air inlet 413, the first air outlet 414 and the fan assembly 200 in sequence, so that the fan assembly 200 provides negative pressure suction to the cleaning base station.

[0090] Reference Figures 2 to 6 As shown, in some embodiments, the transmission unit 430 includes a guide shaft 431 that extends along a first direction. The first end of the guide shaft 431 is located outside the air duct 411, and the second end of the guide shaft 431 is inserted into the air duct 411 and connected to the switching member 420.

[0091] In this way, when an external force drives the guide shaft 431 to move along its own axial direction, the guide shaft 431 can drive the switching member 420 to move back and forth along the first direction, thereby enabling the switching member 420 to flexibly switch between the first working position and the second working position to meet different cleaning needs.

[0092] Reference Figures 2 to 7 As shown, in some embodiments, the transmission unit 430 further includes a link 432, the first end of which is connected to the first end of the guide shaft 431, and the second end of which is configured to abut against the clean base station.

[0093] With this configuration, when the cleaning equipment connects to the cleaning base station, the cleaning base station can abut against the connecting rod 432, thereby applying force to the connecting rod 432, which in turn drives the connecting rod 432 to move. The connecting rod 432 drives the guide shaft 431 to move along the first direction, thereby causing the switching component 420 to move along the first direction to the second working position, so that the fan assembly 200 provides negative pressure suction to the cleaning base station.

[0094] Understandably, after the cleaning equipment disconnects from the cleaning base station, the switching component 420 needs to reset from the second working position to the first working position so that the fan assembly 200 can provide negative pressure suction to the dust cup assembly 300. Therefore, referring to Figure 2 and Figure 3 As shown, in one possible implementation, the air duct switching assembly 400 further includes a reset unit 440, which is connected to the housing 100 and configured to drive the switching element 420 to move from the second working position to the first working position.

[0095] In this way, when the cleaning equipment is disconnected from the cleaning base station, the force exerted by the cleaning base station on the connecting rod 432 disappears, and the reset unit 440 can drive the switching component 420 to move along the first direction, thereby resetting the switching component 420 from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0096] Reference Figures 2 to 7 As shown, in some embodiments, the reset unit 440 includes at least one of a first elastic member 441 and a second elastic member 442. One end of the first elastic member 441 in the direction of elastic force is connected to the housing 100, and the other end of the first elastic member 441 in the direction of elastic force is connected to the guide shaft 431. The elastic force of the first elastic member 441 points from the first working position to the second working position.

[0097] One end of the second elastic element 442 in the direction of elastic force is connected to the housing 100, and the other end of the second elastic element 442 in the direction of elastic force is connected to the connecting rod 432. The elastic force of the second elastic element 442 points from the first working position to the second working position.

[0098] In other words, the reset unit 440 may include a first elastic element 441. When the cleaning equipment is disconnected from the cleaning base station, the force exerted by the cleaning base station on the connecting rod 432 disappears, and the elastic force of the first elastic element 441 can drive the guide shaft 431 to move along the first direction, thereby driving the switching element 420 to reset from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0099] Alternatively, the reset unit 440 may include a second elastic element 442. When the cleaning equipment is disconnected from the cleaning base station, the force exerted by the cleaning base station on the connecting rod 432 disappears, and the second elastic element 442 can drive the connecting rod 432 to move, thereby driving the guide shaft 431 to move along the first direction, thereby driving the switching element 420 to reset from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0100] Alternatively, the reset unit 440 may include a first elastic element 441 and a second elastic element 442. After the cleaning equipment is disconnected from the cleaning base station, the elastic force of the first elastic element 441 can drive the guide shaft 431 to move along the first direction, and the elastic force of the second elastic element 442 can drive the connecting rod 432 to move, thereby driving the guide shaft 431 to move along the first direction, and thus driving the switching element 420 to reset from the second working position to the first working position, so that the cleaning equipment can vacuum the surface to be cleaned.

[0101] In some embodiments, the first air inlet 412 and the second air inlet 413 are located at both ends of the air duct 411, and the first air outlet 414 is located between the two ends of the air duct 411.

[0102] In other words, since the first air outlet 414 is located between the first air inlet 412 and the second air inlet 413, when the switching member 420 moves along the first direction to the side of the first air outlet 414 close to the first air inlet 412, and the switching member 420 is located at any position between the first air inlet 412 and the first air outlet 414, the first air inlet 412 and the first air outlet 414 can be disconnected. At this time, the switching member 420 is in the second working position.

[0103] When the switching component 420 moves along the first direction to the side of the first air outlet 414 close to the second air inlet 413, and the switching component 420 is located at any position between the second air inlet 413 and the first air outlet 414, the second air inlet 413 and the first air outlet 414 can be disconnected. At this time, the switching component 420 is in the first working position. Thus, the switching between the first working position and the second working position can be achieved through the linear movement of the switching component 420.

[0104] Reference Figures 4 to 6 As shown, in one possible implementation, the air duct 411 includes a first air duct section 4111 and a second air duct section 4112 connected in sequence. Both the first air duct section 4111 and the second air duct section 4112 extend along a first direction. The end of the first air duct section 4111 facing away from the second air duct section 4112 forms a first air inlet 412. A first air outlet 414 is located between the two ends of the second air duct section 4112, and the switching member 420 moves back and forth between the two ends of the second air duct section 4112.

[0105] Thus, when the switching component 420 moves along the first direction to the end of the second air duct section 4112 that is close to the first air duct section 4111, the first air duct section 4111 and the second air duct section 4112 can be disconnected, thereby disconnecting the first air inlet 412 and the first air outlet 414, so that the dust cup assembly 300, the cleaning base station, the second air inlet 413, the first air outlet 414 and the fan assembly 200 are connected in sequence.

[0106] When the switching component 420 moves along the first direction to the end of the second air duct section 4112 that is away from the first air duct section 4111, the first air duct section 4111 and the second air duct section 4112 can be connected, thereby connecting the first air inlet 412 and the first air outlet 414, and disconnecting the second air inlet 413 and the first air outlet 414, so that the dust cup assembly 300, the first air inlet 412, the first air outlet 414 and the fan assembly 200 are connected in sequence.

[0107] Reference Figure 6As shown, in some embodiments, the second air duct section 4112 has a first limiting part 4112a at the end away from the first air duct section 4111, and when the switching member 420 is in the first working position, the switching member 420 abuts against the first limiting part 4112a. The second air duct section 4112 has a second limiting part 4112b at the end near the first air duct section 4111, and when the switching member 420 is in the second working position, the switching member 420 abuts against the second limiting part 4112b.

[0108] It is understandable that when the switching member 420 moves along the first direction to abut against the first limiting part 4112a, it indicates that the switching member 420 is in the first working position. When the switching member 420 moves along the first direction to abut against the second limiting part 4112b, it indicates that the switching member 420 is in the second working position. This is beneficial for controlling the movement stroke of the switching member 420, so as to improve the working reliability of the switching member 420.

[0109] Reference Figures 4 to 6 As shown, in one possible implementation, the air duct 411 further includes a third air duct section 4113. The first air duct section 4111, the second air duct section 4112 and the third air duct section 4113 are connected in sequence, and the end of the third air duct section 4113 away from the second air duct section 4112 constitutes the second air inlet 413.

[0110] In other words, when the switching component 420 moves along the first direction to one end of the second air duct section 4112 near the first air duct section 4111, it can connect the second air duct section 4112 and the third air duct 411, and disconnect the first air duct section 4111 and the second air duct section 4112, thereby connecting the second air inlet 413 and the first air outlet 414, and disconnecting the first air inlet 412 and the first air outlet 414, so that the dust cup assembly 300, the cleaning base station, the second air inlet 413, the first air outlet 414 and the fan assembly 200 are connected in sequence.

[0111] When the switching component 420 moves along the first direction to one end of the second air duct section 4112 near the third air duct section 4113, the second air duct section 4112 and the third air duct 411 can be disconnected, and the first air duct section 4111 and the second air duct section 4112 can be connected. This disconnects the second air inlet 413 and the first air outlet 414, and connects the first air inlet 412 and the first air outlet 414, thereby connecting the dust cup assembly 300, the first air inlet 412, the first air outlet 414 and the fan assembly 200 in sequence.

[0112] Reference Figure 3As shown, in some embodiments, the guide shaft 431 includes a first shaft segment 4311 and a second shaft segment 4312 connected in sequence, wherein the diameter of the first shaft segment 4311 is larger than the diameter of the second shaft segment 4312. A switching member 420 is connected to the end of the second shaft segment 4312 near the first shaft segment 4311.

[0113] In this way, the end face of the first shaft segment 4311 near the second shaft segment 4312 can restrict the position of the switching member 420, thereby fixing the switching member 420 at the end of the second shaft segment 4312 near the first shaft segment 4311, so that the guide shaft 431 drives the switching member 420 to move together along the first direction.

[0114] Reference Figure 5 As shown, in one possible implementation, the duct switching assembly 400 further includes a connector 450. The second shaft segment 4312 has an external thread at one end near the first shaft segment 4311, and the connector 450 has an internal thread that matches the external thread, so that the connector 450 is threadedly connected to the second shaft segment 4312. The switching member 420 abuts against the end face of the first shaft segment 4311 near the second shaft segment 4312 and the connector 450.

[0115] Thus, after the connector 450 is threadedly connected to the second shaft segment 4312, the switching member 420 can be fixed between the end face of the first shaft segment 4311 near the second shaft segment 4312 and the connector 450, thereby fixing the switching member 420 to the guide shaft 431, so that the switching member 420 can move synchronously with the guide shaft 431.

[0116] Reference Figure 3 As shown, in one possible implementation, the air duct component 410 has a through hole 415 that communicates with the air duct 411. One end of the first shaft segment 4311 facing away from the second shaft segment 4312 is located outside the air duct 411, and the end of the first shaft segment 4311 near the second shaft segment 4312 is inserted into the air duct 411 through the through hole 415.

[0117] Thus, since the air duct component 410 has a through hole 415 that communicates with the air duct 411, the guide shaft 431 can be inserted into the air duct 411 through the through hole 415, so that the guide shaft 431 can drive the switching component 420 to move within the air duct 411. Furthermore, the end of the first shaft segment 4311 facing away from the second shaft segment 4312 can be connected to the first elastic member 441, so that after the cleaning equipment is disconnected from the cleaning base station, the elastic force of the first elastic member 441 can drive the first shaft segment 4311 to move towards the second shaft segment 4312, thereby causing the switching component 420 to reset from the second working position to the first working position.

[0118] In some embodiments, the second shaft segment 4312 and the through hole 415 are transitionally fitted. That is, the second shaft segment 4312 and the through hole 415 can be either clearance-fitted or interference-fitted, thereby allowing the second shaft segment 4312 to move relative to the through hole 415 in a first direction. This causes the guide shaft 431 to drive the switching member 420 to move in the first direction, and improves the sealing between the second shaft segment 4312 and the through hole 415 to reduce airflow leakage.

[0119] The transition fit between the second shaft section 4312 and the through hole 415 can be between -5mm and 5mm.

[0120] In one possible implementation, the switching element 420 includes an interconnected body and a sealing part, the sealing part being sealed to the inner wall of the air duct 411.

[0121] In other words, the guide shaft 431 can be connected to the main body to drive the switching member 420 to move in the first direction. When the switching member 420 moves to the first working position or the second working position, the sealing part can abut against the inner wall of the air duct 411 to seal the gap between the switching member 420 and the air duct 411, so as to prevent airflow from leaking from the gap between the switching member 420 and the air duct 411, thereby improving the suction of the cleaning equipment or cleaning base station.

[0122] In some embodiments, the sealing portion includes at least one of a first sealing portion and a second sealing portion, wherein the first sealing portion is located on the outer peripheral side of the body and the second sealing portion is located on at least one side of the body along a first direction.

[0123] It is understood that the body can be a thin sheet structure, such as a circular sheet. The first sealing part can be arranged around the outer periphery of the body so that a sealed connection is formed between the outer periphery of the body and the inner wall of the air duct 411. The second sealing part can be arranged on one or both sides of the body in the first direction so that a sealed connection is formed between the two sides of the body and the inner wall of the air duct 411.

[0124] In some implementations, when the cleaning equipment docks with the cleaning base station, the switching component 420 moves from a first working position to a second working position. When the cleaning equipment disengages from the cleaning base station, the switching component 420 moves from the second working position to the first working position. This allows for automatic switching of the switching component 420 without manual intervention.

[0125] The cleaning base station can be equipped with an abutting structure that cooperates with the air duct switching component 400. For example, the cleaning base station can be equipped with an abutting block. When the cleaning equipment docks with the cleaning base station, the abutting block can abut against the connecting rod 432, thereby driving the connecting rod 432 to move away from the cleaning base station. Then, through the guide shaft 431, the switching component 420 moves along the first direction to the second working position, so that the cleaning base station, the second air inlet 413, the first air outlet 414 and the fan component 200 are connected in sequence.
