Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, 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, this application provides a cleaning device and a cleaning system to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a cleaning device, comprising:

[0006] The housing has a mounting cavity, and at least one first connecting part is provided in the mounting cavity;

[0007] The air duct switching mechanism is located in the installation cavity. The air duct switching mechanism has a first air inlet, a second air inlet, a first air outlet, a second air outlet and at least one second connecting part. The second connecting part is slidably connected to the first connecting part in a one-to-one correspondence, so that the air duct switching mechanism can switch between a first working state and a second working state.

[0008] The fan assembly is located inside the mounting cavity;

[0009] Dust cup assembly, the dust cup assembly is connected to the housing;

[0010] In the first working state, the dust cup assembly, the first air inlet, the fan assembly, and the first air outlet are connected in sequence so that the fan assembly provides negative pressure suction to the dust cup assembly. In the second working state, the second air inlet, the fan assembly, the second air outlet, and the dust cup assembly are connected in sequence so that the fan assembly provides positive pressure blowing to the dust cup assembly.

[0011] The cleaning device in this embodiment uses a first connecting part and a second connecting part to cooperate, allowing the air duct switching mechanism to slide relative to the housing, which facilitates switching between a first working state and a second working state. When the air duct switching mechanism is in the first working state, the dust cup assembly, the first air inlet, the fan assembly, and the first air outlet are sequentially connected, allowing the fan assembly to drive external airflow along these components. This allows the cleaning device to use negative pressure suction to draw dirt from the surface to be cleaned into the dust cup assembly. Furthermore, when the air duct switching mechanism is in the second working state, the second air inlet, the fan assembly, the second air outlet, and the dust cup assembly are sequentially connected, allowing the fan assembly to drive external airflow along these components. This allows the cleaning device to use positive pressure to blow dirt from the dust cup assembly to the cleaning base station, enabling the cleaning base station to use the cleaning device's fan assembly for self-dust collection, thereby reducing the cost of the cleaning system.

[0012] In some embodiments, one of the first connecting portion and the second connecting portion includes a groove, and the other includes a protrusion, with an opening on one side of the groove and the protrusion disposed in the groove through the opening.

[0013] Thus, the assembly tolerances of the grooves and protrusions are larger in the radial and circumferential directions of the fan assembly, which can reduce the manufacturing and assembly precision of the first and second connecting parts, thereby reducing the cost of the cleaning equipment.

[0014] In some embodiments, the outer surface of the protrusion facing the groove is an arc surface or a spherical surface, and the inner surface of the groove facing the protrusion is an arc surface.

[0015] In this way, the convex spherical surface can be combined with the concave arc surface to guide the air duct switching mechanism to slide relative to the housing, or the convex arc surface can be combined with the concave arc surface to guide the air duct switching mechanism to slide relative to the housing, thereby facilitating the accurate switching of the air duct switching mechanism between the first working state and the second working state.

[0016] In some embodiments, a groove is provided on the first connecting portion and a protrusion is provided on the second connecting portion.

[0017] This facilitates the machining of protrusions on the air duct switching mechanism and grooves inside the housing, and also facilitates the sliding connection of the first connecting part and the second connecting part when assembling the air duct switching mechanism and the housing.

[0018] In some embodiments, at least two second connections are spaced apart circumferentially along the fan assembly.

[0019] Thus, by arranging multiple first connecting parts and multiple second connecting parts along the circumference of the fan assembly, and through the one-to-one cooperation of the first connecting parts and the second connecting parts, the sliding stability of the duct switching mechanism can be improved.

[0020] In some embodiments, the air duct switching mechanism includes a switching component, the switching component having a fan cavity, the fan cavity having a mounting part, and the fan assembly being disposed in the fan cavity and connected to the mounting part;

[0021] The first air inlet, the second air inlet, the first air outlet, the second air outlet, and the second connecting part are all located on the switching assembly, and the switching assembly is movable relative to the housing;

[0022] When the air duct switching mechanism is in the first working state, the first air inlet, the fan chamber and the first air outlet are connected in sequence; when the air duct switching mechanism is in the second working state, the second air inlet, the fan chamber and the second air outlet are connected in sequence.

[0023] Thus, the air duct switching mechanism can be installed inside the mounting cavity of the housing, and the fan assembly can be installed inside the fan cavity of the switching assembly. Since the fan cavity is located inside the mounting cavity, the structural compactness of the cleaning equipment can be improved, thereby helping to reduce the size of the cleaning equipment. Furthermore, when the switching assembly slides relative to the housing, the first air inlet and the first air outlet can be opened, and the second air inlet and the second air outlet can be closed, or the first air inlet and the first air outlet can be closed, and the second air inlet and the second air outlet can be opened.

[0024] In some embodiments, the first air inlet, the second air outlet, and the dust cup assembly are all located at one end of the fan assembly's axial direction, and the first air outlet is located at the other end of the fan assembly's axial direction.

[0025] Thus, positioning the first air inlet, the second air outlet, and the dust cup assembly at one end of the fan assembly's axial direction shortens the airflow path from the first air inlet to the dust cup assembly, thereby improving the negative pressure suction of the cleaning equipment. It also shortens the airflow path from the second air outlet to the dust cup assembly, thus improving the positive pressure blowing force of the cleaning equipment. Positioning the first air outlet at the other end of the fan assembly's axial direction facilitates the discharge of air into the external environment, further optimizing the airflow path of the cleaning equipment.

[0026] In some embodiments, the switching component includes an air inlet located at one end of the fan assembly along its axial direction and connected to a second connecting portion;

[0027] The air inlet section is provided with a first channel, and a third air inlet is provided at the end of the first channel facing the fan assembly. The third air inlet is connected to the fan cavity.

[0028] The first air inlet and the second air inlet are both located in the air inlet section and are connected to the first channel. The first air inlet and the second air inlet are located on both sides of the third air inlet along the radial direction of the fan assembly. One of the first air inlet and the second air inlet is connected to the third air inlet.

[0029] Thus, when the second connecting part slides forward relative to the first connecting part, it can drive the air inlet part to slide relative to the housing, and when the air duct switching mechanism is in the first working state, the first air inlet and the third air inlet are connected, thereby connecting the dust cup assembly, the first air inlet, the third air inlet, the fan cavity and the first air outlet, so that the cleaning equipment can suck up dust.

[0030] When the second connecting part slides in the opposite direction to the first connecting part, it can drive the air inlet part to slide relative to the housing and put the air duct switching mechanism in the second working state. The second air inlet and the third air inlet are connected, thereby connecting the second air inlet, the third air inlet, the fan cavity, the second air outlet and the dust cup assembly, so that the cleaning base station can collect dust for the cleaning equipment.

[0031] In some embodiments, the air duct switching mechanism further includes a support member, which is fixedly connected to the housing;

[0032] The support member has a recessed cavity, which is open on the side facing the fan assembly, and at least part of the air inlet is located in the recessed cavity;

[0033] The cavity is provided with a first switching part and a second switching part, and the second switching part is provided with a second channel. Both the first switching part and the second channel extend along the circumference of the fan assembly. The first switching part and the second channel are located on both sides of the cavity along the radial direction of the fan assembly. The air inlet is provided with a clearance opening on the side away from the fan cavity, and the second channel is provided with a fourth air inlet on the side facing the first switching part.

[0034] When the air duct switching mechanism is in the first working state, the first switching part is inserted into the first channel through the clearance opening, and the first switching part is positioned between the second air inlet and the third air inlet. The fourth air inlet, the first air inlet, the third air inlet, the fan cavity, and the first air outlet are connected in sequence.

[0035] In this way, the switching component can move relative to the housing and support. When the switching component moves forward, the air inlet moves toward the bottom of the cavity, which can force the first switching part to insert into the first channel and cut off the airflow channel between the second air inlet and the third air inlet. This allows the airflow to flow sequentially along the dust cup assembly, the fourth air inlet, the first air inlet and the third air inlet, the fan cavity and the first air outlet, thereby enabling the fan assembly to provide negative pressure suction for the cleaning equipment to suck away the dirt on the surface to be cleaned.

[0036] In some embodiments, the second channel is provided with a ventilation hole on the side wall away from the first switching part, and a communication port is provided on the side wall away from the fan cavity.

[0037] The switching component also includes an air outlet. Both the air outlet and the air inlet are located at one end of the fan assembly along the axial direction and are connected to each other. The air outlet is positioned closer to the fan assembly than the air inlet, and a second air outlet is located at the air outlet.

[0038] When the air duct switching mechanism is in the second working state, the second air inlet, fan cavity, second air outlet, ventilation hole and connecting port are connected in sequence, and the side wall of the second channel facing the first switching part blocks the first air inlet.

[0039] Thus, when the switching component moves forward, the air inlet moves toward the opening of the cavity, and the first switching component is forced to leave the first channel, thereby connecting the second air inlet with the third air inlet. Furthermore, since the side wall of the second channel toward the first switching component blocks the first air inlet, the airflow channel between the dust cup assembly and the fan cavity can be cut off, thereby allowing the airflow to connect sequentially along the second air inlet, the fan cavity, the second air outlet, the ventilation hole, the connecting port, and the dust cup assembly, thereby allowing the fan assembly to provide positive pressure blowing force to the dust cup assembly, thereby blowing the dirt in the dust cup assembly to the cleaning base station.

[0040] In some embodiments, the air duct switching mechanism further includes a first seal and a second seal, the first seal being connected to the housing, and the first seal and the first air outlet being disposed opposite each other along the axial direction of the fan assembly;

[0041] The second seal is located on the side of the second channel facing the fan cavity and is connected to the second switching part. The second seal and the second air outlet are arranged opposite each other along the axial direction of the fan assembly.

[0042] When the air duct switching mechanism is in the first working state, the second seal seals the second air outlet; when the air duct switching mechanism is in the second working state, the first seal seals the first air outlet.

[0043] Thus, when the duct switching mechanism is in its first operating state, the second air inlet can be closed by the first switching part, and the second air outlet can be closed by the second sealing element, thereby opening the first air inlet and the first air outlet. This connects the dust cup assembly, the first air inlet, the fan chamber, and the first air outlet sequentially. When the duct switching mechanism is in its second operating state, the first air inlet can be closed by the second switching part, and the first air outlet can be closed by the first sealing element, thereby opening the second air inlet and the second air outlet. This connects the second air inlet, the fan chamber, the second air outlet, and the dust cup assembly sequentially. Furthermore, since the first sealing element is installed on the housing and the second sealing element is installed on the support member, the absolute positions of the first and second sealing elements relative to the housing will not change. This ensures that after the switching assembly moves, the first sealing element can reliably close the first air inlet, and the second sealing element can reliably close the second air inlet.

[0044] In some embodiments, the air duct switching mechanism further includes a third seal, which is connected to the first switching part;

[0045] The first channel is provided with a plug-in groove, and the plug-in groove and the clearance opening are arranged opposite to each other along the axial direction of the fan assembly. When the air duct switching mechanism is in the first working state, at least part of the third seal abuts between the first switching part and the clearance opening, and at least part of the third seal abuts between the first switching part and the plug-in groove.

[0046] Thus, when the first switching part is inserted into the first channel and into the insertion slot, the third sealing member abuts against the first switching part and the clearance opening, and the third sealing member abuts against the first switching part and the insertion slot, and the third sealing member can completely cut off the airflow channel between the second air inlet and the third air inlet.

[0047] In some embodiments, the air duct switching mechanism further includes a fourth seal, which is connected to the air inlet and is arranged around the circumference of the first air inlet.

[0048] When the air duct switching mechanism is in the second working state, the fourth seal abuts between the air inlet and the second switching part.

[0049] Thus, when the second channel blocks the first air inlet from the side wall facing the first switching part, the fourth sealing member can abut against the air inlet and the second switching part, thereby sealing the gap between them. This prevents the airflow of the first channel from flowing directly from the gap between the air inlet and the second switching part to the second channel, thereby causing the airflow to flow along the path of the second air inlet, the third air inlet, the fan cavity, the second air outlet, the ventilation hole, the connecting port, and the dust cup assembly.

[0050] In some embodiments, the switching component includes a first switching element and a second switching element, which are connected to jointly define the outlet fan cavity;

[0051] The first air inlet, the second air inlet, and the second air outlet are all located on the first switching component, and the first air outlet and the second connecting part are both located on the second switching component.

[0052] In this way, the first switching component and the second switching component can be processed separately, and the fan assembly can be installed after the second switching component. Then, the first switching component and the second switching component can be connected to form a switching assembly, which facilitates the installation of the fan assembly into the mounting cavity.

[0053] In some embodiments, the switching component further includes a trigger portion, which is configured to drive the air intake portion to move away from the cavity under the action of an external force.

[0054] Thus, when an external force is applied to the triggering part, the second connecting part can be moved away from the support relative to the first connecting part, thereby causing the switching component to move in the opposite direction, and the air duct switching mechanism to switch from the first working state to the second working state, thereby enabling the cleaning base station to collect dust for the cleaning equipment.

[0055] In some embodiments, the air duct switching mechanism further includes an elastic reset member, the two ends of which are respectively connected to the housing and the trigger part. The elastic force of the elastic reset member is consistent with the sliding direction of the second connecting part and points towards the support member.

[0056] Thus, when the external force acting on the triggering part disappears, the switching component can move forward under the elastic force of the elastic reset member, thereby switching the air duct switching mechanism from the second working state to the first working state, which facilitates the cleaning equipment to perform dust extraction.

[0057] 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 automatically collect dust from the cleaning equipment.

[0058] In some embodiments, when the cleaning equipment is connected to the cleaning base station, the air duct switching mechanism switches from a first working state to a second working state.

[0059] When the cleaning equipment disconnects from the cleaning base station, the air duct switching mechanism switches from the second working state to the first working state.

[0060] In this way, the air duct switching mechanism can be automatically switched without manual switching, thereby improving the ease of operation of the cleaning system.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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 in orders other than those illustrated or described herein.

[0088] 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.

[0089] 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.

[0090] However, cleaning stations also require a separate fan, which leads to higher costs for the cleaning system.

[0091] In view of the above problems, this application provides a cleaning device and a cleaning system. By setting an air duct switching mechanism slidably connected to the housing, the air duct switching mechanism can switch between a first working state and a second working state. When the air duct switching mechanism is in the first working state, the fan assembly provides negative pressure suction to the dust cup assembly to suck the dirt on the surface to be cleaned into the dust cup assembly. Alternatively, when the air duct switching mechanism is in the second working state, the fan assembly provides positive pressure blowing to the dust cup assembly to blow the dirt in the dust cup assembly to the cleaning base station. In this way, the cleaning device and the cleaning base station can share the fan assembly, thereby reducing the cost of the cleaning system.

[0092] The specific implementation of the cleaning equipment provided in this embodiment will be described in detail below with reference to the accompanying drawings.

[0093] Reference Figure 1 As shown, the cleaning system provided in this application embodiment includes a cleaning device 10 and a cleaning base station 20, wherein the cleaning base station 20 is configured to perform self-dust collection on the cleaning device 10.

[0094] It should be understood that the cleaning device 10 can be used in conjunction with the cleaning base station 20, or the cleaning device 10 can be used independently. The cleaning device 10 may include a fan assembly 300 and a dust cup assembly 400. When the cleaning device 10 is used independently, the fan assembly 300 provides negative pressure suction to the dust cup assembly 400, thereby drawing dirt from the surface to be cleaned into the dust cup assembly 400, where dust and air are separated, and dust can be collected within the dust cup assembly 400. When the user needs to clean the dust cup assembly 400, the cleaning device 10 can be used in conjunction with the cleaning base station 20, so that the fan assembly 300 provides positive pressure blowing force to the cleaning base station 20, thereby assisting the cleaning base station 20 in recovering dirt from the dust cup assembly 400.

[0095] The cleaning equipment 10 can be a vacuum cleaner, floor scrubber, etc., and this application embodiment does not impose specific limitations on it.

[0096] Reference Figures 1 to 9 As shown, based on the above embodiments, this application also provides a cleaning device 10. The cleaning device 10 includes a housing 100, an air duct switching mechanism 200, a fan assembly 300, and a dust cup assembly 400. The housing 100 is provided with an installation cavity 110, and at least one first connecting part 111 is provided in the installation cavity 110.

[0097] The air duct switching mechanism 200 and the fan assembly 300 are both located in the mounting cavity 110. The dust cup assembly 400 is provided with a dust collection cavity 410. The air duct switching mechanism 200 is provided with a first air inlet 200a, a second air inlet 200b, a first air outlet 200c, a second air outlet 200d, and at least one second connecting part 200e. The second connecting part 200e is slidably connected to the first connecting part 111 in a one-to-one correspondence, so that the air duct switching mechanism 200 switches between the first working state and the second working state.

[0098] In the first working state, the dust collection chamber 410, the first air inlet 200a, the fan assembly 300 and the first air outlet 200c are connected in sequence to enable the cleaning device 10 to suck up dust. In the second working state, the second air inlet 200b, the fan assembly 300, the second air outlet 200d and the dust collection chamber 410 are connected in sequence to enable the cleaning base station 20 to collect dust for the cleaning device 10.

[0099] In this embodiment, the housing 100 is used to install the air duct switching mechanism 200, the fan assembly 300, and the dust cup assembly 400, etc., and then integrates the air duct switching mechanism 200, the fan assembly 300, and the dust cup assembly 400 into a whole cleaning device 10 through the housing 100.

[0100] The fan assembly 300 can be housed in the mounting cavity 110 of the housing 100, which helps to hide the fan assembly 300 and make the cleaning equipment 10 look more aesthetically pleasing. The dust cup assembly 400 is detachably housed outside the mounting cavity 110 of the housing 100 to facilitate cleaning of the dust cup assembly 400.

[0101] The fan assembly 300 provides negative pressure suction to the cleaning device 10, enabling the cleaning device 10 to suck away dirt from the surface to be cleaned and collect the dirt in the dust collection chamber 410 of the dust cup assembly 400. Alternatively, the fan assembly 300 provides positive pressure blowing to the cleaning base station 20, which can collect the dirt in the dust chamber 410, thereby enabling the cleaning base station 20 to perform self-dust collection on the cleaning device 10.

[0102] Specifically, the dust cup assembly 400 may include a cup body 420 and a cup lid 430. The cup body 420 and the cup lid 430 are connected to define the dust collection chamber 410. The cup lid 430 can be opened so that the dust collection chamber 410 can communicate with the dust collection bag of the cleaning base station 20, thereby facilitating the collection of dirt in the dust collection chamber 410.

[0103] Since the air duct switching mechanism 200 is provided with a first air inlet 200a, a second air inlet 200b, a first air outlet 200c, and a second air outlet 200d, and since the housing 100 is provided with a first connecting part 111 and the air duct switching mechanism 200 is provided with a second connecting part 200e, after the first connecting part 111 and the second connecting part 200e are slidably connected, the air duct switching mechanism 200 can move relative to the housing 100, thereby allowing the air duct switching mechanism 200 to switch between different working states.

[0104] The air duct switching mechanism 200 has two working states, namely the first working state and the second working state.

[0105] When the cleaning device 10 is used alone, the air duct switching mechanism 200 can move forward relative to the housing 100 to switch to the first working state. At this time, the first air inlet 200a and the first air outlet 200c are opened, and the second air inlet 200b and the second air outlet 200d are connected. This allows the dust collection chamber 410, the first air inlet 200a, the fan assembly 300 and the first air outlet 200c to be connected in sequence. The airflow can flow along the dust collection chamber 410, the first air inlet 200a, the fan assembly 300 and the first air outlet 200c in sequence. The fan assembly 300 can drive the external airflow to carry the dirt on the surface to be cleaned into the dust collection chamber 410. After the dust and air are separated in the dust collection chamber 410, the dirt is finally discharged to the external environment through the first air outlet 200c. Thus, the cleaning device 10 performs dust suction operation by relying on its own fan assembly 300.

[0106] When the cleaning device 10 is used in conjunction with the cleaning base station 20, the air duct switching mechanism 200 can slide in the opposite direction to the housing 100 to switch to the second working state. At this time, the first air inlet 200a and the first air outlet 200c are closed, and the second air inlet 200b and the second air outlet 200d are open. This allows the second air inlet 200b, the fan assembly 300, the second air outlet 200d, the dust collection chamber 410, and the cleaning base station 20 to be connected in sequence. The airflow can flow sequentially along the second air inlet 200b, the fan assembly 300, the second air outlet 200d, the dust collection chamber 410, and the cleaning base station 20. The fan assembly 300 can drive the external airflow to enter from the second air inlet 200b and blow the dirt in the dust collection chamber 410 to the cleaning base station 20. The airflow is finally discharged to the external environment through the exhaust port of the cleaning base station 20. Thus, the cleaning base station 20 uses the fan assembly 300 of the cleaning device 10 to collect dust by itself, thereby reducing the cost of the cleaning system.

[0107] When the cleaning device 10 is connected to the cleaning base station 20, the cleaning base station 20 provides force to the air duct switching mechanism 200, causing the air duct switching mechanism 200 to switch from a first working state to a second working state. When the cleaning device 10 is disconnected from the cleaning base station 20, the force exerted by the cleaning base station 20 on the air duct switching mechanism 200 disappears, and the air duct switching mechanism 200 switches from the second working state back to the first working state. This allows for automatic switching of the air duct switching mechanism 200 without manual intervention, thereby improving the operational convenience of the cleaning system.

[0108] The cleaning device 10 of this embodiment includes a housing 100, an air duct switching mechanism 200, a fan assembly 300, and a dust cup assembly 400. The housing 100 includes a mounting cavity 110, which includes a first connecting portion 111. The air duct switching mechanism 200 includes a first air inlet 200a, a second air inlet 200b, a first air outlet 200c, a second air outlet 200d, and a second connecting portion 200e. The dust cup assembly 400 includes a dust collection chamber 410. By setting the first connecting part 111 and the second connecting part 200e to cooperate, the air duct switching mechanism 200 is slidably disposed relative to the housing 100, which facilitates the switching of the air duct switching mechanism 200 between the first working state and the second working state. When the air duct switching mechanism 200 is in the first working state, the dust collection chamber 410, the first air inlet 200a, the fan assembly 300 and the first air outlet 200c are connected in sequence, so that the fan assembly 300 can drive the external airflow to flow in sequence along the dust collection chamber 410, the first air inlet 200a, the fan assembly 300 and the first air outlet 200c, thereby allowing the cleaning equipment 10 to use negative pressure suction to clean the surface to be cleaned. The dirt is sucked into the dust collection chamber 410. When the air duct switching mechanism 200 is in the second working state, the second air inlet 200b, the fan assembly 300, the second air outlet 200d and the dust collection chamber 410 are connected in sequence, so that the fan assembly 300 can drive the external airflow to flow in sequence along the second air inlet 200b, the fan assembly 300, the second air outlet 200d and the dust collection chamber 410. This allows the cleaning equipment 10 to blow the dirt in the dust collection chamber 410 to the cleaning base station 20 through positive pressure blowing force. This allows the cleaning base station 20 to use the fan assembly 300 of the cleaning equipment 10 to perform self-dust collection on the cleaning equipment 10, thereby reducing the cost of the cleaning system.

[0109] It is understandable that the first connecting part 111 and the second connecting part 200e cooperate to provide guidance for the movement of the air duct switching mechanism 200, thereby preventing the movement direction of the air duct switching mechanism 200 from deviating, which is conducive to the air duct switching mechanism 200 accurately switching between the first working state and the second working state.

[0110] Reference Figure 4 As shown, in some embodiments, one of the first connecting portion 111 and the second connecting portion 200e includes a groove, and the other includes a protrusion. An opening is provided on one side of the groove, and the protrusion is disposed in the groove through the opening.

[0111] For example, the first connecting portion 111 may include a groove with an opening, and the second connecting portion 200e may include a protrusion such that the protrusion can be inserted into the groove through the opening. Alternatively, the first connecting portion 111 may include a protrusion, and the second connecting portion 200e may include a groove with an opening such that the protrusion can be disposed in the groove through the opening.

[0112] Thus, compared to the guide hole and guide post matching method in related technologies, in this embodiment, since there is an opening on one side of the groove, the assembly tolerance of the groove and the protrusion is larger in the radial direction and the circumferential direction of the fan assembly 300, which can reduce the manufacturing accuracy and assembly accuracy of the first connecting part 111 and the second connecting part 200e, thereby reducing the cost of the cleaning equipment 10.

[0113] In some embodiments, the outer surface of the protrusion facing the groove is an arc surface or a spherical surface, and the inner surface of the groove facing the protrusion is an arc surface.

[0114] In this way, the convex spherical surface can be matched with the concave arc surface to guide the air duct switching mechanism 200 to slide relative to the housing 100, or the convex arc surface can be matched with the concave arc surface to guide the air duct switching mechanism 200 to slide relative to the housing 100, thereby facilitating the accurate switching of the air duct switching mechanism 200 between the first working state and the second working state.

[0115] In some embodiments, a groove is provided on the first connecting portion 111, and a protrusion is provided on the second connecting portion 200e. This arrangement facilitates the machining of a protrusion on the air duct switching mechanism 200 and a groove in the housing 100, and also facilitates the sliding connection of the first connecting portion 111 and the second connecting portion 200e when assembling the air duct switching mechanism 200 and the housing 100.

[0116] In some embodiments, at least two second connecting portions 200e are arranged at circumferential intervals along the fan assembly 300.

[0117] In this way, multiple first connecting parts 111 and multiple second connecting parts 200e are arranged along the circumference of the fan assembly 300, and the one-to-one cooperation between the first connecting parts 111 and the second connecting parts 200e helps to improve the movement stability of the duct switching mechanism 200.

[0118] Reference Figures 5 to 9 As shown, in some embodiments, the air duct switching mechanism 200 includes a switching component 210, which has a fan cavity 211. The fan cavity 211 has a mounting part 2111, and the fan assembly 300 is disposed in the fan cavity 211 and connected to the mounting part 2111. The first air inlet 200a, the second air inlet 200b, the first air outlet 200c, the second air outlet 200d, and the second connecting part 200e are all disposed in the switching component 210, and the switching component 210 is movable relative to the housing 100.

[0119] When the duct switching mechanism 200 is in the first working state, the dust collection chamber 410, the first air inlet 200a, the fan chamber 211, and the first air outlet 200c are connected in sequence. When the duct switching mechanism 200 is in the second working state, the second air inlet 200b, the fan chamber 211, the second air outlet 200d, and the dust collection chamber 410 are connected in sequence.

[0120] In other words, the air duct switching mechanism 200 of this embodiment can be installed in the mounting cavity 110 of the housing 100, and the fan assembly 300 can be installed in the fan cavity 211 of the switching assembly 210. Since the fan cavity 211 is located in the mounting cavity 110, the structural compactness of the cleaning equipment 10 can be improved, which is conducive to reducing the volume of the cleaning equipment 10.

[0121] It is understandable that, since the switching component 210 can slide relative to the housing 100, and the first air inlet 200a, the second air inlet 200b, the first air outlet 200c, and the second air outlet 200d are all located on the switching component 210, it is advantageous to open the first air inlet 200a and the first air outlet 200c and close the second air inlet 200b and the second air outlet 200d, or to close the first air inlet 200a and the first air outlet 200c and open the second air inlet 200b and the second air outlet 200d.

[0122] Meanwhile, the fan assembly 300 can also slide relative to the housing 100 along with the switching assembly 210. Since the first connecting part 111 and the second connecting part 200e adopt a groove and a protrusion matching method, it is beneficial for the fan assembly 300 to be centered when sliding.

[0123] In some embodiments, the first air inlet 200a, the second air inlet 200b, the second air outlet 200d and the dust cup assembly 400 are all located at one end of the axial direction of the fan assembly 300, and the first air outlet 200c is located at the other end of the axial direction of the fan assembly 300.

[0124] It should be noted that when the air duct switching mechanism 200 is in the first working state, the dust collection chamber 410 needs to be connected to the first air inlet 200a. Therefore, placing both the first air inlet 200a and the dust cup assembly 400 at one end of the fan assembly 300 in the axial direction helps to shorten the flow path of the airflow from the first air inlet 200a to the dust collection chamber 410, thereby helping to improve the negative pressure suction of the cleaning equipment 10.

[0125] Since the second air outlet 200d needs to be connected to the dust collection chamber 410 when the air duct switching mechanism 200 is in the second working state, the second air outlet 200d and the dust cup assembly 400 are located at one end of the fan assembly 300 in the axial direction. This helps to shorten the flow path of the airflow from the second air outlet 200d to the dust collection chamber 410, and thus helps to improve the positive pressure blowing force of the cleaning equipment 10.

[0126] The first air outlet 200c is located at the other end of the fan assembly 300 along the axis, which is conducive to the discharge to the external environment through the first air outlet 200c, thereby optimizing the airflow path of the cleaning equipment 10.

[0127] Reference Figures 8 to 11 As shown, in one possible implementation, the switching component 210 includes an air inlet 212, which is located at one end of the fan assembly 300 along its axial direction and connected to the second connecting portion 200e. The air inlet 212 has a first channel 2121, and a third air inlet 2122 is provided at the end of the first channel 2121 facing the fan assembly 300. The third air inlet 2122 communicates with the fan chamber 211.

[0128] The first air inlet 200a and the second air inlet 200b are both located in the air inlet section 212 and are connected to the first channel 2121. The first air inlet 200a and the second air inlet 200b are located on both sides of the third air inlet 2122 along the radial direction of the fan assembly 300. One of the first air inlet 200a and the second air inlet 200b is connected to the third air inlet 2122.

[0129] Thus, when the second connecting part 200e slides forward relative to the first connecting part 111, it can drive the air inlet part 212 to slide relative to the housing 100, and when the air duct switching mechanism 200 is in the first working state, the first air inlet 200a is connected to the third air inlet 2122, thereby connecting the dust collection chamber 410, the first air inlet 200a, the third air inlet 2122, the fan chamber 211 and the first air outlet 200c, so that the cleaning equipment 10 can suck up dust.

[0130] When the second connecting part 200e slides in the opposite direction to the first connecting part 111, it can drive the air inlet part 212 to slide relative to the housing 100, and put the air duct switching mechanism 200 in the second working state. The second air inlet 200b is connected to the third air inlet 2122, thereby connecting the second air inlet 200b, the third air inlet 2122, the fan chamber 211, the second air outlet 200d and the dust collection chamber 410, so that the cleaning base station 20 can collect dust for the cleaning equipment 10.

[0131] Reference Figures 6 to 14As shown, in one possible implementation, the air duct switching mechanism 200 further includes a support member 220, which is fixedly connected to the housing 100. The support member 220 has a cavity 221, open on the side facing the fan assembly 300, with at least a portion of the air inlet 212 located within the cavity 221. The cavity 221 has a first switching portion 2211 and a second switching portion 2212, the second switching portion 2212 having a second channel 22121. Both the first switching portion 2211 and the second channel 22121 extend circumferentially along the fan assembly 300, and are located on both sides of the cavity 221 along the radial direction of the fan assembly 300. The side of the air inlet 212 away from the fan cavity 211 has a clearance opening 2123, and the side of the second channel 22121 facing the first switching portion 2211 has a fourth air inlet 22122.

[0132] When the air duct switching mechanism 200 is in the first working state, the first switching part 2211 is inserted into the first channel 2121 through the clearance port 2123, and the first switching part 2211 is positioned between the second air inlet 200b and the third air inlet 2122. The fourth air inlet 22122, the first air inlet 200a and the third air inlet 2122, the fan cavity 211 and the first air outlet 200c are connected in sequence.

[0133] In this way, the switching component 210 can move relative to the housing 100 and the support 220. The switching component 210 and the housing 100 are slidably connected through the cooperation of the first connecting part 111 and the second connecting part 200e. When the switching component 210 moves forward, the air inlet 212 moves toward the bottom of the cavity 221, which can force the first switching part 2211 to insert into the first channel 2121 and cut off the airflow channel between the second air inlet 200b and the third air inlet 2122. This allows the airflow to flow sequentially along the dust collection chamber 410, the fourth air inlet 22122, the first air inlet 200a and the third air inlet 2122, the fan chamber 211 and the first air outlet 200c, thereby enabling the fan component 300 to provide negative pressure suction for the cleaning device 10 to suck away the dirt on the surface to be cleaned.

[0134] The switching component 210 and the support member 220 can switch the airflow path through the cooperation of the air inlet 212, the first switching part 2211 and the second switching part 2212, so that the air duct switching mechanism 200 can switch from the second working state to the first working state.

[0135] Reference Figure 8 , Figure 9 , Figure 12 , Figure 13As shown, in some embodiments, the second channel 22121 has a ventilation hole 22123 on its side wall away from the first switching part 2211, and a connecting port 22124 on its side wall away from the fan cavity 211. The switching assembly 210 also includes an air outlet 213. The air outlet 213 and the air inlet 212 are both located at one end of the fan assembly 300 along the axial direction and are connected to each other. The air outlet 213 is disposed close to the fan assembly 300 relative to the air inlet 212, and the second air outlet 200d is disposed on the air outlet 213.

[0136] When the air duct switching mechanism 200 is in the second working state, the second air inlet 200b, the fan cavity 211, the second air outlet 200d, the ventilation hole 22123, the connecting port 22124 and the dust collection chamber 410 are connected in sequence, and the second channel 22121 blocks the first air inlet 200a on the side wall facing the first switching part 2211.

[0137] Thus, when the switching component 210 moves forward, the air inlet 212 moves toward the opening of the cavity 221, and the first switching part 2211 is forced to leave the first channel 2121, thereby connecting the second air inlet 200b with the third air inlet 2122. Furthermore, since the second channel 22121 blocks the first air inlet 200a from the side wall of the first switching part 2211, the airflow channel between the dust collection chamber 410 and the fan chamber 211 can be cut off. This allows the airflow to sequentially connect the second air inlet 200b, the fan chamber 211, the second air outlet 200d, the ventilation hole 22123, the connecting port 22124, and the dust collection chamber 410, thereby allowing the fan component 300 to provide positive pressure blowing force to the dust cup component 400, thereby blowing the dirt in the dust collection chamber 410 to the cleaning base station 20.

[0138] Reference Figures 5 to 9 , Figure 12 As shown, in one possible implementation, the air duct switching mechanism 200 further includes a first seal 230 and a second seal 240. The first seal 230 is connected to the housing 100, and the first seal 230 and the first air outlet 200c are arranged opposite each other along the axial direction of the fan assembly 300. The second seal 240 is located on the side of the second channel 22121 facing the fan cavity 211 and is connected to the second switching part 2212. The second seal 240 and the second air outlet 200d are arranged opposite each other along the axial direction of the fan assembly 300.

[0139] When the air duct switching mechanism 200 is in the first working state, the second sealing element 240 seals the second air outlet 200d, and when the air duct switching mechanism 200 is in the second working state, the first sealing element 230 seals the first air outlet 200c.

[0140] Thus, when the duct switching mechanism 200 is in the first working state, the second air inlet 200b can be closed by the first switching part 2211, and the second air outlet 200d can be closed by the second sealing element 240, thereby opening the first air inlet 200a and the first air outlet 200c, so that the dust collection chamber 410, the first air inlet 200a, the fan chamber 211, and the first air outlet 200c are connected in sequence. When the duct switching mechanism 200 is in the second working state, the first air inlet 200a can be closed by the second switching part 2212, and the first air outlet 200c can be closed by the first sealing element 230, thereby opening the second air inlet 200b and the second air outlet 200d, so that the second air inlet 200b, the fan chamber 211, the second air outlet 200d, and the dust collection chamber 410 are connected in sequence. Furthermore, since the first seal 230 is installed on the housing 100 and the second seal 240 is installed on the support 220, the absolute positions of the first seal 230 and the second seal 240 relative to the housing 100 will not change. This ensures that after the switching assembly 210 moves, the first seal 230 can reliably close the first air inlet 200a and the second seal 240 can reliably close the second air inlet 200b.

[0141] Reference Figure 8 , Figure 9 As shown, in one possible implementation, the duct switching mechanism 200 further includes a third seal 250 connected to the first switching part 2211. A insertion groove 2124 is provided in the first channel 2121. The insertion groove 2124 and the clearance opening 2123 are arranged opposite each other along the axial direction of the fan assembly 300. When the duct switching mechanism 200 is in its first working state, at least a portion of the third seal 250 abuts against the first switching part 2211 and the clearance opening 2123, and at least a portion of the third seal 250 abuts against the first switching part 2211 and the insertion groove 2124.

[0142] With this configuration, when the first switching part 2211 is inserted into the first channel 2121 and into the insertion slot 2124, the third sealing member 250 abuts against the first switching part 2211 and the clearance opening 2123, thus sealing the gap between the first switching part 2211 and the clearance opening 2123. The third sealing member 250 abuts against the first switching part 2211 and the insertion slot 2124, thus sealing the gap between the first switching part 2211 and the insertion slot 2124, thereby completely cutting off the airflow channel between the second air inlet 200b and the third air inlet 2122.

[0143] Reference Figure 8 , Figure 9As shown, in one possible implementation, the air duct switching mechanism 200 further includes a fourth seal 260, which is connected to the air inlet 212 and arranged circumferentially around the first air inlet 200a. When the air duct switching mechanism 200 is in the second working state, the fourth seal 260 abuts between the air inlet 212 and the second switching part 2212.

[0144] Thus, when the second channel 22121 blocks the first air inlet 200a from the side wall of the first switching part 2211, the fourth seal 260 can abut against the air inlet 212 and the second switching part 2212, thereby sealing the gap between them. This prevents the airflow of the first channel 2121 from flowing directly from the gap between the air inlet 212 and the second switching part 2212 to the second channel 22121, thereby causing the airflow to flow along the path of the second air inlet 200b, the third air inlet 2122, the fan chamber 211, the second air outlet 200d, the ventilation hole 22123, the connecting port 22124, and the dust collection chamber 410.

[0145] Reference Figure 11 As shown, in some embodiments, the switching assembly 210 includes a first switching member 210a and a second switching member 210b, which are connected to jointly define the exhaust fan cavity 211. A first air inlet 200a, a second air inlet 200b, and a second air outlet 200d are both located on the first switching member 210a, and a first air outlet 200c and a second connecting portion 200e are both located on the second switching member 210b.

[0146] Thus, the switching assembly 210 is divided into a first switching component 210a and a second switching component 210b. The first switching component 210a and the second switching component 210b can be processed separately, and the fan assembly 300 can be installed onto the second switching component 210b. Then, the first switching component 210a and the second switching component 210b are connected to form the switching assembly 210, which facilitates the installation of the fan assembly 300 into the mounting cavity 110.

[0147] Reference Figures 5 to 11 As shown, in some embodiments, the switching component 210 is further provided with a trigger part 214, which is configured to drive the air intake part 212 to move away from the cavity 221 under the action of an external force.

[0148] For example, a hand can provide external force to the trigger part 214, or the cleaning base station 20 can be equipped with a trigger mechanism. When the trigger part 214 comes into contact with the trigger mechanism, the trigger mechanism can provide external force to the trigger part 214, thereby causing the second connecting part 200e to move away from the support member 220 relative to the first connecting part 111, thereby causing the switching component 210 to move in the opposite direction, thereby causing the air duct switching mechanism 200 to switch from the first working state to the second working state, so that the cleaning base station 20 can collect dust for the cleaning equipment 10.

[0149] Reference Figures 5 to 7 , Figure 10 , Figure 11 As shown, in one possible implementation, the air duct switching mechanism 200 further includes an elastic reset member 270. The two ends of the elastic reset member 270 are respectively connected to the housing 100 and the trigger part 214. The elastic force of the elastic reset member 270 is consistent with the sliding direction of the second connecting part 200e and points towards the support member 220.

[0150] When the external force acting on the trigger 214 disappears, the switching component 210 can move forward under the elastic force of the elastic reset member 270, thereby switching the air duct switching mechanism 200 from the second working state to the first working state, so as to facilitate the cleaning equipment 10 to perform vacuuming.

[0151] It should be noted that the forward movement of the air duct switching mechanism 200 / switching component 210 and the reverse movement of the air duct switching mechanism 200 / switching component 210 described in this embodiment refer to the two movements being in opposite directions and do not constitute a specific limitation on the direction of movement.

[0152] For example, refer to Figure 2 As shown, when the duct switching mechanism 200 moves downward along the axial direction of the fan assembly 300, it can be considered that the duct switching mechanism 200 moves in the forward direction, and when the duct switching mechanism 200 moves upward along the axial direction of the fan assembly 300, it can be considered that the duct switching mechanism 200 moves in the reverse direction.

[0153] The fan assembly 300 may include a motor and an impeller arranged coaxially. The motor has a drive shaft to drive the impeller to rotate, thereby causing airflow. The axial direction of the fan assembly 300 can be understood as the axial direction of the drive shaft, the radial direction of the fan assembly 300 can be understood as the radial direction of the drive shaft, and the circumferential direction of the fan assembly 300 can be understood as the circumferential direction of the drive shaft.

[0154] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
