Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning appliances, in particular to a cleaning device and a cleaning system. BACKGROUND

[0002] In the related art, a cleaning system can include a cleaning base station and a cleaning device. The cleaning base station can charge the cleaning device and perform a self-dust collection operation. The cleaning device includes a device host and a dust cup. The device host can provide a negative pressure suction force, so that the cleaning device can suck dirt on a surface to be cleaned into the dust cup when the cleaning device is working. When the cleaning device is docked with the cleaning base station, the lid of the dust cup is opened, and then the dirt in the dust cup is cleaned by the self-dust collection function of the cleaning base station.

[0003] However, the cleaning base station also needs to be provided with a separate fan, which results in a high cost of the cleaning system. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the embodiments of the present application provide a cleaning device and a cleaning system, which have a low cost.

[0005] In a first aspect, the embodiments of the present application provide a cleaning device, which includes a shell, a fan assembly, a dust cup assembly, an air duct switching assembly, and a first movement assembly. The fan assembly and the dust cup assembly are both connected to the shell.

[0006] The air duct switching assembly includes an air duct piece and a switching piece. The air duct piece is connected to the shell. The air duct piece has an air cavity, a first air inlet, a second air inlet, and a first air outlet, which are in communication with each other. The first air inlet is in communication with the dust cup assembly. The second air inlet is configured to be in communication with the cleaning base station. The first air outlet is in communication with the fan assembly.

[0007] The switching piece is arranged in the air cavity and is movably connected to the air duct piece. The switching piece has a first working position and a second working position. When the switching piece is in the first working position, the switching piece opens the first air inlet and closes the second air inlet. When the switching piece is in the second working position, the switching piece opens the second air inlet and closes the first air inlet.

[0008] The first movement assembly includes a first gear piece and a second gear piece that are movably connected to each other. The first gear piece is connected to the shell. The second gear piece is connected to the switching piece to drive the switching piece to rotate relative to the air duct piece.

[0009] The cleaning device provided in this application embodiment has a housing for installing a fan assembly, a dust cup assembly, an air duct switching assembly, and a first motion 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 ventilation chamber and the dust cup assembly, a second air inlet connects the ventilation chamber and the cleaning base station, and a first air outlet connects the ventilation chamber and the fan assembly. A switching element opens one of the first and second air inlets and closes the other. The first motion assembly drives the switching element to rotate, allowing it to switch positions. This enables the switching element to control the fan assembly to provide negative pressure suction to either the dust cup assembly or the cleaning base station, allowing the cleaning base station and the cleaning device to share a single fan assembly, thus reducing the cost of the cleaning base station. Furthermore, since the first motion component includes a first gear and a second gear, and the second gear is connected to the switching component, when the force is transmitted to the switching component along the first gear and the second gear, the power transmission becomes more stable and reliable. This allows the switching component to reliably open the first air inlet and close the second air inlet, or to reliably open the second air inlet and close the first air inlet.

[0010] In one possible implementation, the switching element has a convex surface that protrudes outward toward the outside of the air cavity when the switching element is in the first working position.

[0011] Thus, when the switching component closes the second air inlet, its convex surface protrudes outward toward the outside of the air cavity, thereby increasing the surface area of ​​the switching component in contact with the outside atmosphere. This reduces the atmospheric pressure per unit area of ​​the switching component, allowing a smaller force to keep the switching component in the closed state of the second air inlet. Furthermore, the convex surface protruding outward toward the outside of the air cavity keeps the center of gravity of the switching component away from the center of the air cavity, preventing the switching component from rotating due to negative pressure suction. This makes the closing of the second air inlet by the switching component more reliable.

[0012] In one possible implementation, the switching element also has a concave surface, with the convex and concave surfaces located on opposite sides of the switching element, and the concave direction of the concave surface being consistent with the convex direction of the convex surface.

[0013] In this way, the mass of the switching component can be reduced, so that the switching component can be flexibly switched between the first working position and the second working position. It also allows the concave side of the switching component to form a cavity, so that when the switching component is in the second working position, the center of gravity of the switching component is far away from the center of the air cavity, thereby effectively preventing the switching component from rotating under the action of negative pressure suction and opening the second air inlet.

[0014] In one possible implementation, the first air inlet and the second air inlet are located on adjacent sides of the air cavity, and the switching component is rotatably connected to the air duct component.

[0015] Thus, when the switching component rotates at a preset angle in a preset direction, it can switch from the first working position to the second working position. When the switching component rotates at the same angle in the opposite direction, it can switch from the second working position to the first working position. The control of the switching component is relatively flexible and convenient.

[0016] In one possible implementation, the cleaning device further includes a first motion component, which is movably connected to the housing and connected to a switching element to drive the switching element to rotate relative to the air duct component.

[0017] Thus, since the first motion component is movably connected to the housing, the first motion component can move relative to the housing, thereby driving the switching component to rotate, so that the switching component can switch from the first working position to the second working position, or from the second working position to the first working position.

[0018] In one possible implementation, the cleaning device further includes a second motion component movably connected to the housing. One of the first and second motion components is configured to dock with the cleaning base station to drive the switching element to a second working position, and the other of the first and second motion components is configured to drive the switching element to a first working position.

[0019] Thus, by cooperating with the first and second motion components, the switching element can switch back and forth between the first and second working positions, thereby facilitating flexible switching according to cleaning needs such as vacuuming or self-collecting dust.

[0020] In one possible implementation, the first motion component includes a first gear and a second gear that mesh with each other, the first gear cooperating with the second motion component and the second gear connected to a switching component.

[0021] Thus, the first gear can act as the driving component to drive the second motion component to move, or it can act as the driven component to rotate under the drive of the second motion component. The second gear can act as the transmission component to rotate under the drive of the first gear, thereby driving the switching component to rotate.

[0022] In one possible implementation, the second motion component includes a movable rod movably disposed on the housing and moving relative to the housing along its own length.

[0023] Thus, when an external force is applied to the moving rod, the moving rod can move along its own length toward the first gear, thereby causing the first and second gears to rotate, which in turn drives the switching component to move from the first working position to the second working position. Alternatively, the external force applied to the first gear can be transmitted to the moving rod, thereby causing the moving rod to move away from the first gear along its own length.

[0024] In one possible implementation, the first gear is configured to dock with the clean base station, and the first gear drives the switching component to move to the second working position.

[0025] Thus, when the cleaning equipment connects to the cleaning base station, the force of the cleaning base station is applied to the first gear component, which causes the first gear component to rotate. This, in turn, drives the switching component to move from the first working position to the second working position through the second gear component, thereby enabling the fan assembly to provide negative pressure suction to the cleaning base station.

[0026] In one possible implementation, the second motion component further includes a first elastic element, the two ends of which are connected to the housing and the moving rod, respectively. The elastic force of the first elastic element is directed from the moving rod to the first gear component, and is configured to drive the switching component to move to the first working position.

[0027] Thus, the elastic force of the first elastic element can drive the moving rod to rotate toward the first gear, and the moving rod can drive the first gear to rotate, thereby causing the second gear to drive the switching element to move from the second working position to the first working position.

[0028] In one possible implementation, the movable rod is configured to dock with the base station, and the movable rod abuts against the first gear component to drive the switching component to move to the second working position.

[0029] Thus, when the cleaning equipment connects to the cleaning base station, the force of the cleaning base station is applied to the moving rod, which in turn moves the moving rod toward the first gear component, thereby causing the second gear component to move the switching component from the first working position to the second working position to open the second air inlet, so that the fan assembly provides negative pressure suction to the cleaning base station.

[0030] In one possible implementation, the first motion component further includes a second elastic element, the two ends of which are connected to the housing and the first gear component respectively, and are configured to drive the first gear component to rotate so as to move the switching component to the first working position.

[0031] Thus, when the cleaning equipment disconnects from the cleaning base station, the force exerted by the cleaning base station on the moving rod disappears, and the elastic force of the second elastic element can drive the first gear to rotate, thereby driving the second gear to rotate, which in turn drives the switching element to reset from the second working position to the first working position, and drives the moving rod to move away from the first gear.

[0032] In one possible implementation, the first gear component includes a gear body and an abutment portion connected to the outside of the gear body. The gear body meshes with the second gear component, and the abutment portion abuts against a moving rod, or the abutment portion is configured to dock with a clean base station.

[0033] In this way, the force of cleaning the base station or the force of moving the rod can be applied to the abutment, thereby driving the abutment to move, which in turn causes the gear body to rotate. Since the gear body meshes with the second gear, it can drive the second gear to rotate, thereby driving the switching component to rotate.

[0034] In one possible implementation, the first motion component further includes a third gear, which meshes with the second gear.

[0035] In this way, power can be transmitted from the first gear to the third gear, and then from the third gear to the second gear. The second gear then drives the switching component to rotate. The third gear can also change the transmission ratio between the first and second gears, making the power transmission smoother.

[0036] In one possible implementation, the housing also has a dust collection duct with a third air inlet and a second air outlet, the second air outlet being connected to the second air inlet, and the third air inlet being configured to be connected to the clean base station.

[0037] Thus, when the cleaning equipment is connected to the cleaning base station, the switching component is in the second working position, the first air inlet is closed and the second air inlet is open. At this time, the second air inlet and the second air outlet are in a connected state, and the fluid can flow sequentially along the cleaning base station, the third air inlet, the dust collection duct, the second air outlet, the second air inlet, the air cavity, the first air outlet and the fan assembly, thereby enabling the cleaning base station to use the negative pressure suction of the fan assembly to collect dust from the dust cup assembly.

[0038] Secondly, this application provides 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 self-collect dust from the cleaning equipment.

[0039] 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; when the cleaning equipment disconnects from the cleaning base station, the switching component moves from the second working position to the first working position.

[0040] 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

[0057] 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. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] However, cleaning stations also require a separate fan, which leads to higher costs for the cleaning system.

[0064] Based on 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 cleaning system can work together with the fan component of the cleaning device to collect dust, thereby reducing the cost of the cleaning system.

[0065] The specific implementation of the cleaning equipment provided in this application will be described in detail below with reference to the accompanying drawings.

[0066] Reference Figure 1 and Figure 2 As shown, the cleaning system provided in this application includes a cleaning base station and cleaning equipment, and the cleaning base station can collect dust for the cleaning equipment.

[0067] In this embodiment, the cleaning device can be used in conjunction with a cleaning base station, or it can be used independently. The cleaning device may include a fan assembly 200 and a dust cup assembly. When used independently, the fan assembly 200 provides negative pressure suction to the dust cup assembly, drawing dirt from the surface to be cleaned into the dust cup assembly, where dust and air are separated and collected. When the user needs to clean the dust cup assembly, the cleaning device can be used in conjunction with a cleaning base station, allowing the fan assembly 200 to provide negative pressure suction to the cleaning base station, thereby assisting the cleaning base station in recovering dirt from the dust cup assembly.

[0068] The cleaning equipment can be a vacuum cleaner, a floor scrubber, etc., and this application does not limit this.

[0069] Reference Figures 1 to 5As 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 (not shown in the figure), and an air duct switching assembly 300. The fan assembly 200 and the dust cup assembly are both connected to the housing 100, and the dust cup assembly has a dust collection chamber.

[0070] The air duct switching assembly 300 includes an air duct component 310 and a switching component 320. The air duct component 310 is connected to the housing 100. The air duct component 310 has an interconnected air cavity 311, a first air inlet 312, a second air inlet 313, and a first air outlet 314. The first air inlet 312 is configured to communicate with the dust collection cavity, the second air inlet 313 is configured to communicate with the cleaning base station, and the first air outlet 314 is configured to communicate with the fan assembly 200.

[0071] The switching element 320 is disposed in the air cavity 311 and is movably connected to the air duct 310. The switching element 320 has a first working position and a second working position. When the switching element 320 is in the first working position, the switching element 320 opens the first air inlet 312 and closes the second air inlet 313. When the switching element 320 is in the second working position, the switching element 320 opens the second air inlet 313 and closes the first air inlet 312.

[0072] The switching component 320 has a convex surface 321, which protrudes outward toward the air cavity 311 when the switching component 320 is in the first working position.

[0073] In this embodiment, the housing 100 is used to install the fan assembly 200, the dust cup assembly, and the air duct switching assembly 300, thereby integrating the housing 100, fan assembly 200, dust cup assembly, and air duct switching assembly 300 into a cleaning device. The fan assembly 200 provides negative pressure suction for the cleaning device or cleaning base station. When the fan assembly 200 provides negative pressure suction for the cleaning device, the cleaning device can suck away dirt from the surface to be cleaned and collect the dirt in the dust collection chamber of the dust cup assembly. When the fan assembly 200 provides negative pressure suction for the cleaning base station, the cleaning base station can collect the dirt in the dust chamber, thereby enabling the cleaning base station to perform self-dust collection on the cleaning device.

[0074] Specifically, the air duct switching component 300 includes an air duct component 310 and a switching component 320. The air duct component 310 and the switching component 320 work together to form different airflow channels, thereby enabling the fluid to achieve different flow paths through the air duct switching component 300. This allows the fan component 200 to provide negative pressure suction for both cleaning equipment and cleaning base stations.

[0075] It is understood that the air duct component 310 may have an air cavity 311, which has a first air inlet 312, a second air inlet 313 and a first air outlet 314. The first air inlet 312 is connected to the dust cup assembly, the second air inlet 313 is connected to the cleaning base station, and the first air outlet 314 is connected to the fan assembly 200. The switching component 320 can switch between a first working position and a second working position.

[0076] When the cleaning equipment docks with the cleaning base station, the switching component 320 moves from the first working position to the second working position. When the cleaning equipment disengages from the cleaning base station, the switching component 320 moves from the second working position to the first working position. This allows for automatic switching of the switching component 320 without manual intervention. Figure 3 This indicates that the switching unit 320 is in the first working position. Figure 4 This indicates that the switching element 320 is in the second working position.

[0077] Thus, when the switching element 320 is in the first working position, the dust cup assembly, the first air inlet 312, the air cavity 311, the first air outlet 314, and the fan assembly 200 are sequentially connected, forming an airflow channel for dust collection. When the switching element 320 is in the second working position, the cleaning base station, the second air inlet 313, the air cavity 311, the first air outlet 314, and the fan assembly 200 are sequentially connected, forming an airflow channel for self-collecting dust. This allows the cleaning base station and the cleaning equipment to share a single fan assembly 200, eliminating the need for an additional fan assembly 200 at the cleaning base station, thereby reducing the cost of the cleaning system.

[0078] Understandably, when the cleaning equipment is in the vacuuming working state, that is, when the switching element 320 is in the first working position, the switching element 320 closes the second air inlet 313. The outside of the switching element 320 is the atmospheric environment, and the inside of the switching element 320 is the air cavity 311, which is under negative pressure. Since the outside of the switching element 320 is a convex surface 321 at this time, the convex surface 321 can increase the outer surface area of ​​the switching element 320, thereby reducing the atmospheric pressure per unit area on the outside of the switching element 320. Thus, the switching element 320 can be kept in the second working position with a smaller force to reliably close the second air inlet 313.

[0079] Furthermore, since the convex surface 321 protrudes outward toward the air cavity 311 at this time, the center of gravity of the switching component 320 can be moved away from the center position of the air cavity 311, thereby enabling the switching component 320 to better resist the rotational torque caused by the negative pressure suction, thus preventing the switching component 320 from rotating under the action of negative pressure suction and opening the second air inlet 313, thereby improving the working reliability of the switching component 320.

[0080] It should be understood that if the second air inlet 313 is opened when the cleaning equipment is vacuuming, airflow will leak from the second air inlet 313, which will reduce the suction power of the cleaning equipment and thus affect the vacuuming effect of the cleaning equipment.

[0081] The cleaning equipment provided in this application includes a housing 100, a fan assembly 200, a dust cup assembly, and an air duct switching assembly 300. The dust cup assembly includes a dust collection chamber. The air duct switching assembly 300 includes an air duct component 310 and a switching component 320. The air duct component 310 includes an air cavity 311, a first air inlet 312, a second air inlet 313, and a first air outlet 314. The switching component 320 includes a convex surface 321. By configuring a housing 100 for mounting the fan assembly 200, dust cup assembly, and air duct switching assembly 300, by configuring the fan assembly 200 for providing negative pressure suction, by configuring a dust collection chamber for collecting dirt from the surface to be cleaned, by configuring a first air inlet 312 for connecting the ventilation chamber 311 and the dust collection chamber, by configuring a second air inlet 313 for connecting the ventilation chamber 311 and the cleaning base station, by configuring a first air outlet 314 for connecting the ventilation chamber 311 and the fan assembly 200, and by configuring a switching element 320 for opening one of the first air inlet 312 and the second air inlet 313 and closing the other of the first air inlet 312 and the second air inlet 313, the switching element 320 can control the fan assembly 200 to provide negative pressure suction to either the dust cup assembly or the cleaning base station. This allows the cleaning base station and the cleaning equipment to share a single fan assembly 200, thereby reducing the cost of the cleaning base station. Furthermore, since the convex surface 321 of the switching component 320 protrudes outward toward the air cavity 311 when the second air inlet 313 is closed, the surface area of ​​the switching component 320 in contact with the outside atmosphere can be increased, thereby reducing the atmospheric pressure per unit area of ​​the switching component 320. Thus, a smaller force can be used to keep the switching component 320 in the closed state of the second air inlet 313. Moreover, the convex surface 321 protruding outward toward the air cavity 311 can keep the center of gravity of the switching component 320 away from the center of the air cavity 311, thereby preventing the switching component 320 from rotating due to negative pressure suction. Thus, the switching component 320 can close the second air inlet 313 more reliably.

[0082] Reference Figure 3 As shown, in one possible implementation, the switching member 320 also has a concave surface 322, with the convex surface 321 and the concave surface 322 located on opposite sides of the switching member 320, and the concave direction of the concave surface 322 being consistent with the convex direction of the convex surface 321.

[0083] This design reduces the mass of the switching element 320, allowing it to switch flexibly between the first and second working positions. It also allows the side of the switching element 320 with the concave surface 322 to form a cavity, so that when the switching element 320 is in the second working position, its center of gravity is far away from the center of the air cavity 311, thus effectively preventing the switching element 320 from rotating under the negative pressure suction and opening the second air inlet 313.

[0084] For example, the switching element 320 can be a spherical plate with uniform wall thickness, and the central angle between the convex surface 321 and the concave surface 322 can be between 120° and 180° to effectively increase the contact area between the convex surface 321 and the atmosphere.

[0085] Reference Figure 3 , Figure 4 As shown, in some embodiments, the air duct switching assembly 300 may further include at least one seal 330, which is disposed on the side of the switching member 320 having a convex surface 321 to improve the sealing between the switching member 320 and the second air inlet 313; or, at least one seal 330 is disposed on the side of the switching member 320 having a concave surface 322 to improve the sealing between the switching member 320 and the first air inlet 312.

[0086] In some embodiments, the first air inlet 312 and the second air inlet 313 are located on adjacent sides of the air cavity 311, and the switching member 320 is rotatably connected to the air duct member 310.

[0087] In this way, when the switching element 320 rotates in the preset direction and at the preset angle, the switching element 320 can switch from the first working position to the second working position. When the switching element 320 rotates in the opposite direction and at the same angle, the switching element 320 can switch from the second working position to the first working position. The control of the switching element 320 is more flexible and convenient.

[0088] Reference Figure 2 , Figure 6 and Figure 7 As shown, in one possible implementation, the cleaning device further includes a first motion component 400, which is movably connected to the housing 100 and connected to the switching component 320 to drive the switching component 320 to rotate relative to the air duct component 310.

[0089] In this way, since the first motion component 400 is movably connected to the housing 100, the first motion component 400 can move relative to the housing 100, thereby driving the switching component 320 to rotate, so that the switching component 320 can switch from the first working position to the second working position, or from the second working position to the first working position.

[0090] Understandably, when the cleaning equipment is connected to the cleaning base station, the cleaning base station can perform self-dust collection on the cleaning equipment. In this case, the switching unit 320 needs to switch from the first working position to the second working position. When the cleaning equipment is disconnected from the cleaning base station, the cleaning equipment can perform vacuuming operations independently. In this case, the switching unit 320 needs to switch from the second working position to the first working position. The switching unit 320 needs to alternate between the first and second working positions to meet different cleaning needs.

[0091] Therefore, refer to Figure 2 , Figure 6 and Figure 7 As shown, in one possible implementation, the cleaning device further includes a second motion component 500, which is movably connected to the housing 100. One of the first motion component 400 and the second motion component 500 is configured to dock with the cleaning base station to drive the switching member 320 to a second working position, and the other of the first motion component 400 and the second motion component 500 is configured to drive the switching member 320 to a first working position.

[0092] For example, when the first motion component 400 docks with the cleaning base station, the first motion component 400 drives the switching component 320 to switch from the first working position to the second working position, so that the cleaning base station, the second air inlet 313, the air cavity 311, the first air outlet 314, and the fan assembly 200 are connected in sequence, thereby facilitating the cleaning base station to use the negative pressure suction of the fan assembly 200 to collect dirt in the dust cup assembly. When the first motion component 400 disengages from the cleaning base station, the second motion component 500 drives the switching component 320 to reset, so that the switching component 320 switches from the second working position to the first working position, thereby facilitating the dust cup assembly, the first air inlet 312, the air cavity 311, the first air outlet 314, and the fan assembly 200 are connected in sequence, thereby facilitating the cleaning equipment to vacuum the surface to be cleaned.

[0093] For example, when the second motion component 500 docks with the cleaning base station, the second motion component 500 drives the switching component 320 to switch from the first working position to the second working position, so that the cleaning base station, the second air inlet 313, the air cavity 311, the first air outlet 314, and the fan assembly 200 are connected in sequence, thereby facilitating the cleaning base station to use the negative pressure suction of the fan assembly 200 to collect dirt in the dust cup assembly. When the second motion component 500 disengages from the cleaning base station, the first motion component 400 drives the switching component 320 to reset, so that the switching component 320 switches from the second working position to the first working position, thereby connecting the dust cup assembly, the first air inlet 312, the air cavity 311, the first air outlet 314, and the fan assembly 200 in sequence, thereby facilitating the cleaning equipment to vacuum the surface to be cleaned.

[0094] With this configuration, the first motion component 400 and the second motion component 500 work together to allow the switching component 320 to switch back and forth between the first working position and the second working position, thereby facilitating switching according to cleaning needs such as vacuuming or self-collecting dust.

[0095] Reference Figure 6 and Figure 7 As shown, in some embodiments, the first motion component 400 includes a first gear 410 and a second gear 420 that are meshed with each other. The first gear 410 cooperates with the second motion component 500, and the second gear 420 is connected to the switching component 320.

[0096] For example, when the second motion component 500 docks with the cleaning base station, the force of the cleaning base station is applied to the second motion component 500, which in turn causes the second motion component 500 to drive the first gear component 410 to rotate. The first gear component 410 drives the switching component 320 to rotate forward, thereby causing the switching component 320 to switch from the first working position to the second working position.

[0097] Alternatively, when the first gear component 410 is connected to the cleaning base station, the force of the cleaning base station is applied to the first gear component 410, which causes the first gear component 410 to rotate in the forward direction. The first gear component 410 drives the switching component 320 to rotate, thereby causing the switching component 320 to switch from the first working position to the second working position.

[0098] Alternatively, when the first gear component 410 disengages from the cleaning base station, the force of the second motion component 500 is applied to the first gear component 410, thereby causing the first gear component 410 to reverse, so that the second gear component 420 drives the switching component 320 to switch from the second working position to the first working position.

[0099] In this way, the first gear 410 can act as the driving member to drive the second motion component 500 to move, and the first gear 410 can also act as the driven member to rotate under the drive of the second motion component 500. The second gear 420 can act as the transmission member to rotate under the drive of the first gear 410, thereby driving the switching member 320 to rotate.

[0100] Reference Figure 2 , Figure 6 and Figure 7 As shown, in one possible implementation, the second motion component 500 includes a moving rod 510, which is movably disposed in the housing 100 and moves relative to the housing 100 along its own length.

[0101] Thus, when an external force is applied to the moving rod 510, such as the force of cleaning the base station or the force of a hand, the moving rod 510 can move along its own length toward the first gear 410, thereby causing the first gear 410 and the second gear 420 to rotate, thereby driving the switching member 320 to move from the first working position to the second working position. Alternatively, the external force applied to the first gear 410 can be transmitted to the moving rod 510, thereby causing the moving rod 510 to move away from the first gear 410 along its own length.

[0102] In some embodiments, the first gear 410 is configured to dock with a clean base station, and the first gear 410 drives the switching member 320 to move to a second working position.

[0103] In this way, when the cleaning equipment connects with the cleaning base station, the force of the cleaning base station is applied to the first gear component 410, which causes the first gear component 410 to rotate. Then, through the second gear component 420, the switching component 320 is driven to move from the first working position to the second working position, so that the fan assembly 200 provides negative pressure suction to the cleaning base station.

[0104] Reference Figure 2 , Figure 6 and Figure 7 As shown, in one possible implementation, the second motion component 500 further includes a first elastic element 520, the two ends of which are connected to the housing 100 and the moving rod 510 respectively. The elastic force of the first elastic element 520 points from the moving rod 510 to the first gear component 410, and is configured to drive the switching component 320 to move to the first working position.

[0105] Understandably, after the cleaning equipment is disconnected from the cleaning base station, the switching component 320 needs to be reset to the first working position. Since the first elastic component 520 is connected to the moving rod 510, the elastic force of the first elastic component 520 can drive the moving rod 510 to rotate toward the first gear component 410. In this way, the moving rod 510 can drive the first gear component 410 to rotate, thereby causing the second gear component 420 to drive the switching component 320 to move from the second working position to the first working position.

[0106] For example, the first elastic element 520 can be a spring.

[0107] In some embodiments, the movable rod 510 is configured to dock with the base station, and the movable rod 510 abuts against the first gear member 410 to drive the switching member 320 to move to the second working position.

[0108] In this way, when the cleaning equipment is connected to the cleaning base station, the force of the cleaning base station is applied to the moving rod 510, which in turn drives the moving rod 510 to move toward the first gear 410, thereby causing the second gear 420 to drive the switching component 320 to move from the first working position to the second working position, so as to open the second air inlet 313, thereby enabling the fan assembly 200 to provide negative pressure suction to the cleaning base station.

[0109] In one possible implementation, the first motion component 400 further includes a second elastic element (not shown in the figure), the two ends of which are connected to the housing 100 and the first gear component 410 respectively, and are configured to drive the first gear component 410 to rotate so as to move the switching component 320 to the first working position.

[0110] In other words, when the cleaning equipment is disconnected from the cleaning base station, the force exerted by the cleaning base station on the moving rod 510 disappears, and the elastic force of the second elastic element can drive the first gear 410 to rotate, thereby driving the second gear 420 to rotate, thereby driving the switching element 320 to reset from the second working position to the first working position, and driving the moving rod 510 to move away from the first gear 410.

[0111] For example, the second elastic element can be a coil spring.

[0112] Reference Figure 6 and Figure 7 As shown, in a specific implementation, the first gear component 410 includes a gear body 411 and an abutment portion 412. The abutment portion 412 is connected to the outside of the gear body 411. The gear body 411 meshes with the second gear component 420. The abutment portion 412 abuts against the moving rod 510, or the abutment portion 412 is configured to dock with the clean base station.

[0113] With this configuration, the force of cleaning the base station or the force of moving rod 510 can be applied to the abutment part 412, thereby driving the abutment part 412 to move, which in turn causes the gear body 411 to rotate. Since the gear body 411 meshes with the second gear 420, it can drive the second gear 420 to rotate, thereby driving the switching member 320 to rotate.

[0114] Reference Figure 6 and Figure 7 As shown, in one possible implementation, the first motion component 400 further includes a third gear 430, through which the first gear 410 meshes with the second gear 420.

[0115] In this way, power can be transmitted from the first gear 410 to the third gear 430, and then from the third gear 430 to the second gear 420. The second gear 420 then drives the switching member 320 to rotate. The third gear 430 can change the transmission ratio between the first gear 410 and the second gear 420, making the power transmission smoother.

[0116] Reference Figure 3 and Figure 4 As shown, in one possible implementation, the housing 100 also has a dust collection duct 110, which has a third air inlet and a second air outlet. The second air outlet is connected to the second air inlet 313, and the third air inlet is configured to be connected to the clean base station.

[0117] Thus, when the cleaning equipment is connected to the cleaning base station, the switching component 320 is in the second working position, the first air inlet 312 is closed and the second air inlet 313 is open. At this time, the second air inlet 313 and the second air outlet are in a connected state, and the fluid can flow sequentially along the cleaning base station, the third air inlet, the dust collection duct 110, the second air outlet, the second air inlet 313, the air cavity 311, the first air outlet 314 and the fan assembly 200, thereby enabling the cleaning base station to use the negative pressure suction of the fan assembly 200 to collect dust from the dust cup assembly.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
