Description

Technical Field

[0001] This application relates to the field of cleaning device technology, and in particular to an air duct structure, cleaning equipment, and cleaning system. Background Technology

[0002] As living standards improve, people have higher requirements for the quality of their living environment, and household dust removal devices such as vacuum cleaners and floor scrubbers are increasingly appearing in people's lives.

[0003] In related technologies, a cleaning system may include a base station and a cleaning device. The cleaning device is detachably connected to the base station. The cleaning device includes a device body and a dust cup mounted on the device body, with an openable end cap on the dust cup. When the device body is in operation, it can suck debris from the surface to be cleaned into the dust cup. When the base station is connected to the device body, it can open the end cap and then clean the debris in the dust cup through its self-collecting dust program.

[0004] However, this also requires a separate suction motor for the base station, resulting in higher costs for the cleaning system. Utility Model Content

[0005] This application provides an air duct structure, cleaning equipment, and cleaning system to solve the problem that both base stations and handheld devices require independent suction motors, resulting in high costs for cleaning devices.

[0006] Firstly, the air duct structure provided in this application includes:

[0007] A support assembly is provided for connecting to the motor assembly of the cleaning equipment. The support assembly is provided with a first air duct and a second air duct for communicating with the motor assembly.

[0008] The air duct switching assembly has a third air duct and a fourth air duct. The third air duct is used to communicate with the dust cup assembly of the cleaning equipment. The air duct switching assembly is connected to the support assembly and can move relative to the support assembly to switch between a first state and a second state.

[0009] In the first state, the first air duct is connected to the third air duct, and the second air duct and the fourth air duct are closed, so that the dust cup assembly and the motor assembly are connected; in the second state, the first air duct and the third air duct are closed, and the second air duct is connected to the fourth air duct; when the second air duct and the fourth air duct are connected, the dust cup assembly, the base station, the fourth air duct, the second air duct and the motor assembly are connected in sequence, so that the base station collects debris from the dust cup assembly.

[0010] Thus, by moving the air duct switching component relative to the support component, the air duct switching component switches between a first state and a second state. In the first state, the dust cup assembly and the motor assembly are connected, and the motor assembly provides suction to collect debris from the surface to be cleaned into the dust cup assembly. In the second state, the motor assembly is connected to the base station, and the motor assembly provides suction to collect debris from the dust cup assembly into the dust collection chamber of the base station. In this way, the entire cleaning system can operate with only one motor assembly, reducing costs.

[0011] In one possible implementation, the air duct structure provided in this application includes the following supporting components:

[0012] A mounting base is used to connect to the motor assembly, and a second air duct is set on the mounting base;

[0013] A support component is mounted on a fixed base, and the first air duct is located on the support component.

[0014] In the first state, the air duct switching component opens the first air duct and closes the second air duct; in the second state, the air duct switching component closes the first air duct and opens the second air duct.

[0015] By separating the first and second air ducts, the misalignment of the first and second air ducts during switching is avoided, which would affect the user experience.

[0016] In one possible implementation, the air duct structure provided in this application has a mounting sleeve on the fixing base, and the support member is inserted into the mounting sleeve;

[0017] The mounting sleeve is provided with multiple first through holes, and each first through hole is spaced apart around the periphery of the mounting sleeve, forming a second air duct.

[0018] Thus, the second air duct is formed by multiple first through holes spaced apart around the periphery of the mounting sleeve, which provides more flow paths for the airflow, increases the intake volume, and accelerates the airflow rate to improve the suction efficiency of the motor assembly.

[0019] In one possible implementation, the air duct structure provided in this application has at least one first connecting part on the fixed base, the first connecting part being used for sliding connection with the air duct switching component;

[0020] And / or, the mounting base has at least one first guide portion for sliding connection with the duct switching assembly.

[0021] In this way, the air duct switching component can switch between the first and second states by sliding, making it convenient for the user to switch. Furthermore, the first guide portion guides the sliding path of the air duct switching component, preventing it from deviating from the sliding path and thus avoiding the inability to accurately close the first or second air duct.

[0022] In one possible implementation, the first connecting part of the air duct structure provided in this application is a limiting rod;

[0023] And / or, the first guide part is a guide post.

[0024] In this way, the air duct switching component can slide relative to the limit rod and be confined on the limit rod, preventing the air duct switching component from falling off the limit rod. The guide post is used to guide the air duct switching component to slide along the specified sliding path, preventing the air duct switching component from deviating from the sliding path.

[0025] In one possible implementation, the air duct structure provided in this application includes a support plate and a first baffle ring disposed on the support plate. The support plate has a plurality of second through holes, each of which is located within the area enclosed by the first baffle ring, and the second through holes together form a first air duct.

[0026] Thus, the support member can be inserted into the mounting sleeve of the fixed base through the first retaining ring, which facilitates the corresponding installation of the support member and the fixed base. Furthermore, the first air duct is formed by multiple second through holes, which provides more flow paths for the airflow, increases the intake volume, and accelerates the airflow rate, thereby improving the suction efficiency of the motor assembly.

[0027] In one possible implementation, the air duct structure provided in this application further includes a first seal in the support assembly;

[0028] The first sealing element is sleeved on the support and abuts between the mounting sleeve and the support;

[0029] The support component is located inside the air duct switching component, and the end of the first seal opposite to the support component abuts against the air duct switching component to seal the gap between the air duct switching component and the support component.

[0030] In this way, the gap between the mounting sleeve and the support is sealed by the first seal, preventing air leakage through the gap between the mounting sleeve and the support. Furthermore, the gap between the air duct switching assembly and the support assembly is sealed by the first seal, preventing air leakage.

[0031] In one possible implementation, the air duct structure provided in this application includes a moving part in the air duct switching component;

[0032] The movable component includes a base and a second retaining ring disposed on the base;

[0033] The second baffle ring is slidably connected to the support component, and multiple third through holes are provided on the base. Each third through hole is located in the area enclosed by the second baffle ring, and each third through hole forms a third air duct.

[0034] Multiple fourth through holes are provided on the second baffle ring, and each fourth through hole is spaced apart around the circumference of the second baffle ring, forming a fourth air duct.

[0035] Thus, when the air duct switching assembly moves toward the support assembly, the base can close the first air duct on the support plate, and the fourth air duct on the second retaining ring can connect with the second air duct on the mounting sleeve. When the air duct switching assembly moves away from the support assembly, the base opens the first air duct on the support plate, so that the first air duct connects with the third air duct on the base, and the second retaining ring closes the second air duct on the mounting sleeve.

[0036] In one possible implementation, the air duct structure provided in this application has a first sealing member on the base, and the first sealing member is located in the area enclosed by the second baffle ring;

[0037] In the first state, the first sealing element opens the first air duct; in the second state, the first sealing element closes the first air duct.

[0038] Thus, when the air duct switching component moves toward the support component, the first air duct can be blocked by the first sealing member. When the air duct switching component moves away from the support component, the first sealing member opens the first air duct.

[0039] In one possible implementation, the air duct structure provided in this application has a first sealing element as a plug, which is inserted into the first air duct to seal it.

[0040] Thus, the structure is simple and compact, making it easy to open or block the first air duct.

[0041] In one possible implementation, the air duct structure provided in this application further includes a second seal in the air duct switching component;

[0042] The second sealing element is fitted onto the plug to seal the gap between the plug and the first air duct.

[0043] In this way, by sealing the gap between the plug and the first air duct with the second seal, the airflow is prevented from leaking through the first air duct when the air duct switching component is in the second state.

[0044] In one possible implementation, the air duct structure provided in this application has a second sealing element that is a conical sealing ring, and the plug has a conical head that matches the inner ring of the conical sealing ring, with the conical sealing ring fitted onto the conical head.

[0045] Thus, when the plunger moves toward the second through hole, the conical head can guide the plunger to engage with the second through hole, thereby preventing jamming.

[0046] In one possible implementation, the air duct structure provided in this application has at least one second connecting portion on the second baffle ring, the second connecting portion being used for sliding connection with the support component;

[0047] And / or, the second retaining ring has at least one second guide portion for sliding connection with the support assembly.

[0048] In this way, the air duct switching component can slide relative to the support component, and it also guides the sliding path of the air duct switching component.

[0049] In one possible implementation, the air duct structure provided in this application has a second connecting part as a limiting hole;

[0050] And / or, the second guide part is a guide hole.

[0051] Thus, the limiting hole can correspond to the limiting rod of the first connecting part to limit the air duct switching component onto the limiting rod. The guide hole can correspond to the guide rod of the first guide part to provide a guiding function.

[0052] In one possible implementation, the air duct structure provided in this application further includes a second sealing member in the air duct switching component. The second sealing member is disposed between the second baffle ring and the support component, and the fourth air duct is located between the second sealing member and the third air duct.

[0053] In the first state, the second sealing element closes the second air duct; in the second state, the second sealing element opens the second air duct.

[0054] Thus, the second closure can be used to close or open the second air duct.

[0055] In one possible implementation, the air duct structure provided in this application includes a second sealing member comprising a first sealing joint, an elastic member, and a second sealing joint connected in sequence.

[0056] The first sealing joint is sleeved on the support assembly, the second sealing joint is inserted into the movable part, and the elastic element is located between the first sealing joint and the second sealing joint.

[0057] In the first state, the elastic element seals the second air duct; in the second state, the elastic element is compressed to open the second air duct.

[0058] In this way, the second air duct can be sealed or opened by changing the relative position of the first sealing joint and the second sealing joint, so that the elastic element can be extended or compressed.

[0059] In one possible implementation, the air duct structure provided in this application also includes a reset component;

[0060] The air duct switching component is connected to the support component through a reset component, and the reset component drives the air duct switching component to switch from the second state to the first state.

[0061] In this way, the air duct switching component can be quickly switched from the second state to the first state by the reset component.

[0062] Secondly, the cleaning equipment provided in this application includes the equipment body and the air duct structure as described above, with the air duct structure disposed within the equipment body.

[0063] Thus, in the first state, the dust cup assembly and motor assembly on the device body can be connected through the first and third air ducts of the air duct switching assembly, and the motor assembly provides suction to collect debris on the surface to be cleaned into the dust cup assembly.

[0064] Thirdly, the cleaning system provided in this application includes a base station and the cleaning equipment as described above, wherein the base station is used to collect debris from the dust cup assembly of the cleaning equipment.

[0065] Thus, in the second state, the air duct of the base station and the motor assembly of the cleaning equipment can be connected through the second and fourth air ducts. The motor assembly provides suction to collect debris from the dust cup assembly of the cleaning equipment into the dust collection chamber of the base station.

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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] In related technologies, a cleaning system may include a base station and a cleaning device. The cleaning device is detachably connected to the base station. The cleaning device includes a device body and a dust cup mounted on the device body, with an openable end cap on the dust cup. When the device body is in operation, it can suck debris from the surface to be cleaned into the dust cup. When the base station is connected to the device body, it can open the end cap and then clean the debris in the dust cup through its self-collecting dust program.

[0096] However, this also requires a separate suction motor for the base station, resulting in higher costs for the cleaning system.

[0097] In view of the above problems, this application provides an air duct structure, a cleaning device, and a cleaning system. The air duct structure includes a support assembly and an air duct switching assembly. The support assembly has a first air duct and a second air duct for communication with a motor assembly. The air duct switching assembly has a third air duct and a fourth air duct. The third air duct is for communication with the dust cup assembly of the cleaning device. The air duct switching assembly is connected to the support assembly and is movable relative to the support assembly to switch between a first state and a second state. In the first state, the dust cup assembly and the motor assembly are connected, and the motor assembly provides suction to collect debris from the surface to be cleaned into the dust cup assembly. In the second state, the motor assembly is connected to a base station, and the motor assembly provides suction to collect debris from the dust cup assembly into the dust collection chamber of the base station. Thus, the entire cleaning system can operate with only one motor assembly, reducing costs.

[0098] The following describes in detail, with reference to the accompanying drawings, the specific implementation methods of the air duct structure, cleaning equipment, and cleaning system provided in the embodiments of this application.

[0099] It should also be noted that the air duct structure provided in this application can be applied to various cleaning devices. Specifically, the cleaning device includes a dust cup assembly and a motor assembly. The motor assembly provides suction to collect debris from the surface to be cleaned into the dust cup assembly. Furthermore, this cleaning device can be used in various cleaning systems, which include the cleaning device and a base station. The base station can open and communicate with the dust cup assembly of the cleaning device to collect debris from within it.

[0100] Reference Figure 1 and Figure 2 As shown, the air duct structure 101 provided in this application includes a support component 100 and an air duct switching component 200.

[0101] The support assembly 100 is used to connect to the motor assembly 102 of the cleaning equipment 10. The support assembly 100 is provided with a first air duct 1001 and a second air duct 1002 for communicating with the motor assembly 102.

[0102] The air duct switching assembly 200 has a third air duct 2001 and a fourth air duct 2002. The third air duct 2001 is used to communicate with the dust cup assembly 103 of the cleaning device 10. The air duct switching assembly 200 is connected to the support assembly 100 and the air duct switching assembly 200 is movable relative to the support assembly 100 to switch between a first state and a second state.

[0103] In the first state, the first air duct 1001 is connected to the third air duct 2001, and the second air duct 1002 and the fourth air duct 2002 are closed, so that the dust cup assembly 103 and the motor assembly 102 are connected. In the second state, the first air duct 1001 and the third air duct 2001 are closed, and the second air duct 1002 is connected to the fourth air duct 2002; when the second air duct 1002 and the fourth air duct 2002 are connected, the dust cup assembly 103, the base station 20, the fourth air duct 2002, the second air duct 1002 and the motor assembly 102 are connected in sequence, so that the base station 20 collects debris from the dust cup assembly 103.

[0104] It is understood that the air duct structure 101 provided in this application can be installed within a cleaning device 10, which has a dust cup assembly 103, which has a dust collection port and an end cap. When the cleaning device 10 is cleaning the surface to be cleaned, the user can switch the air duct switching assembly 200 to a first state. In this state, the first air duct 1001 is connected to the third air duct 2001, while the second air duct 1002 and the fourth air duct 2002 are closed, thus connecting the dust cup assembly 103 and the motor assembly 102. (Refer to...) Figures 5 to 8 As shown, the motor assembly 102 provides suction force, and the airflow enters the dust cup assembly 103 through the dust collection port, and then flows through the third air duct 2001, the first air duct 1001 and the motor assembly 102 in sequence, and finally is discharged through the exhaust port on the dust cup assembly 103, thereby collecting the debris on the surface to be cleaned through the dust collection port of the dust cup assembly 103.

[0105] Additionally, it should be understood that the base station 20 in the cleaning system has a dust collection chamber 201 and an air duct 202, with the dust collection chamber 201 connected to the air duct 202. When the cleaning device 10 is docked with the base station 20, the base station 20 can open the end cap of the dust cup assembly 103 to connect the dust cup assembly 103 to the dust collection chamber 201, and the air duct 202 can be used to connect to the second air duct 1002 and the fourth air duct 2002.

[0106] In this way, the user can switch the air duct switching component 200 to the second state. At this state, the first air duct 1001 and the third air duct 2001 are closed, thus sealing the dust cup assembly 103 and the motor assembly 102. The second air duct 1002 and the fourth air duct 2002 are connected, thereby sequentially connecting the air guide channel 202, the fourth air duct 2002, the second air duct 1002, and the motor assembly 102 of the base station 20. (Refer to...) Figures 8 to 14As shown, the suction force provided by the motor assembly 102 causes airflow to enter the dust cup assembly 103 through the dust collection port, and then flow sequentially through the dust collection chamber 201, the air guide channel 202, the fourth air duct 2002, the second air duct 1002 and the motor assembly 102, and finally be discharged through the exhaust port on the dust cup assembly 103, thereby collecting the debris in the dust cup assembly 103 into the dust collection chamber 201 of the base station 20.

[0107] Of course, in other embodiments, an air inlet may be provided separately on the dust cup assembly 103. When the base station 20 collects debris in the dust cup assembly 103, the airflow enters the dust cup assembly 103 through the air inlet. This application embodiment does not impose specific limitations on this.

[0108] The air duct structure 101 provided in this application allows the air duct switching component 200 to move relative to the support component 100, switching between a first state and a second state. In the first state, the dust cup component 103 and the motor component 102 are connected, and the motor component 102 provides suction to collect debris from the surface to be cleaned into the dust cup component 103. In the second state, the motor component 102 is connected to the base station 20, and the motor component 102 provides suction to collect debris from the dust cup component 103 into the dust collection chamber 201 of the base station 20. Thus, the entire cleaning system can operate with only one motor component 102, reducing costs.

[0109] Reference Figure 2 and Figure 3 As shown, in some embodiments, the support assembly 100 includes a base 110 and a support member 120.

[0110] The mounting base 110 is used to connect to the motor assembly 102, and the second air duct 1002 is disposed on the mounting base 110. The support member 120 is disposed on the mounting base 110, and the first air duct 1001 is located on the support member 120.

[0111] In the first state, the air duct switching component 200 opens the first air duct 1001 and closes the second air duct 1002; in the second state, the air duct switching component 200 closes the first air duct 1001 and opens the second air duct 1002.

[0112] Understandably, both the first air duct 1001 and the second air duct 1002 are used to connect to the motor assembly 102. In the first state, the air duct switching component 200 opens the first air duct 1001 and closes the second air duct 1002, so that the motor assembly 102, the first air duct 1001, the third air duct 2001 on the air duct switching component 200, and the dust cup assembly 103 are connected in sequence. In the second state, the air duct switching component 200 closes the first air duct 1001 and opens the second air duct 1002, so that the motor assembly 102, the second air duct 1002, the fourth air duct 2002 on the air duct switching component 200, and the air guide channel 202 of the base station 20 are connected in sequence.

[0113] In this way, the first air duct 1001 is set on the support member 120, and the second air duct 1002 is set on the fixed base 110, so that the first air duct 1001 and the second air duct 1002 are set separately, so as to avoid the first air duct 1001 and the second air duct 1002 being misaligned when the air duct switching component 200 switches, for example, the first air duct 1001 is connected to the fourth air duct 2002, and the second air duct 1002 is connected to the third air duct 2001, which would affect the user experience.

[0114] Reference Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 110 has a mounting sleeve 111, and the support member 120 is inserted into the mounting sleeve 111.

[0115] The mounting sleeve 111 is provided with a plurality of first through holes 1111, each first through hole 1111 being spaced apart around the periphery of the mounting sleeve 111, and each first through hole 1111 forming a second air duct 1002.

[0116] The support member 120 is inserted into the mounting sleeve 111, which makes the structure simple and compact and allows for easy insertion and assembly of the support member 120 and the fixed base 110.

[0117] The second air duct 1002 is formed by a plurality of first through holes 1111 spaced apart around the periphery of the mounting sleeve 111. This provides more flow paths for the airflow in the second state of the air duct switching assembly 200, increases the intake volume, and accelerates the flow rate of the airflow, thereby improving the suction efficiency of the motor assembly 102.

[0118] For example, the shape of the first through hole 1111 can be circular, elliptical, square, triangular, etc., and the embodiments of this application do not impose specific limitations on this.

[0119] Reference Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 110 has at least one first connecting portion 112 for sliding connection with the air duct switching assembly 200.

[0120] And / or, the mounting base 110 has at least one first guide portion 113 for sliding connection with the air duct switching assembly 200.

[0121] In this way, the air duct switching component 200 can be slidably mounted on the first connecting part 112, so that the air duct switching component 200 can switch between the first state and the second state by sliding, which is convenient for the user to perform the switching operation.

[0122] The first guide part 113 is slidably connected to the air duct switching component 200. The first guide part 113 guides the air duct switching component 200 to slide along the specified sliding path, so as to avoid the air duct switching component 200 deviating from the sliding path and thus failing to accurately close the first air duct 1001 or the second air duct 1002.

[0123] It is understood that there is at least one first connecting part 112, and the number of first connecting parts 112 can be one or more. The embodiments of this application do not impose too many restrictions on this.

[0124] It is understood that there is at least one first guide portion 113, and the number of first guide portions 113 can be one or more. The embodiments of this application do not impose too many restrictions on this.

[0125] Reference Figure 2 and Figure 3 As shown, in some embodiments, the first connecting part 112 is a limiting rod.

[0126] And / or, the first guide part 113 is a guide post.

[0127] The end of the limiting rod away from the fixed base 110 may be provided with a limiting part, so that the air duct switching assembly 200 can slide relative to the limiting rod, and the limiting part of the limiting rod limits the air duct switching assembly 200 to the limiting rod, preventing the air duct switching assembly 200 from falling off the limiting rod. The guide post is used to guide the air duct switching assembly 200 to slide along a specified sliding path, preventing the air duct switching assembly 200 from deviating from the sliding path.

[0128] Reference Figure 2 and Figure 3 As shown, in some embodiments, the support member 120 includes a support plate 121 and a first retaining ring 122 disposed on the support plate 121. The support plate 121 has a plurality of second through holes 1211, each of which is located in the area enclosed by the first retaining ring 122, and each of the second through holes 1211 together forms a first air duct 1001.

[0129] Understandably, the support member 120 can be inserted into the mounting sleeve 111 of the fixed base 110 via the first retaining ring 122, which facilitates the corresponding installation of the support member 120 and the fixed base 110. The outer side of the first retaining ring 122 may be provided with a snap-fit ​​portion, and the inner side of the mounting sleeve 111 may be provided with a snap-fit ​​groove adapted to the snap-fit ​​portion. The assembly of the support member 120 and the fixed base 110 is achieved by the snap-fit ​​portion engaging with the snap-fit ​​groove.

[0130] The first air duct 1001 is formed by multiple second through holes 1211, which provides more flow paths for airflow in the first state of the air duct switching component 200, increases the intake volume, and accelerates the flow rate of airflow, thereby improving the suction efficiency of the motor component 102.

[0131] Reference Figure 2 and Figure 3 As shown, in some embodiments, the support assembly 100 further includes a first seal 130.

[0132] The first sealing element 130 is sleeved on the support element 120 and abuts between the mounting sleeve 111 and the support element 120.

[0133] The support component 100 is partially located within the air duct switching component 200, and the end of the first seal 130 facing away from the support component 100 abuts against the air duct switching component 200 to seal the gap between the air duct switching component 200 and the support component 100.

[0134] For example, the first seal 130 may be disposed between the mounting sleeve 111 and the support plate 121 of the support member 120 to seal the gap between the mounting sleeve 111 and the support member 120 and prevent airflow from leaking through the gap between the mounting sleeve 111 and the support member 120.

[0135] Furthermore, refer to Figure 3 , Figure 4 and Figure 5 As shown, the support member 120 is inserted into the mounting sleeve 111 of the fixed base 110. The support plate 121 of the support member 120 is located at the end of the mounting sleeve 111. The first air duct 1001 is located on the support member 120, and the second air duct 1002 is located on the side wall of the mounting sleeve 111. When the air duct switching component 200 moves towards the support component 100, it can close the first air duct 1001 and open the second air duct 1002, which is the second state of the air duct switching component 200. When the air duct switching component 200 moves away from the support component 100, it can open the first air duct 1001 and close the second air duct 1002, which is the first state of the air duct switching component 200.

[0136] Since the support component 100 is partially located inside the air duct switching component 200, a clearance needs to be left between the support component 100 and the air duct switching component 200 so that the air duct switching component 200 can slide relative to the support component 100. The clearance is sealed by the first seal 130 to prevent air leakage.

[0137] For example, the first sealing element 130 can be a silicone element, a rubber element, or other sealing material with a certain elasticity. This application embodiment does not specifically limit this.

[0138] Reference Figure 2 and Figure 4 As shown, in some embodiments, the air duct switching assembly 200 includes a movable element 210, which includes a base 211 and a second retaining ring 212 disposed on the base 211.

[0139] The second baffle ring 212 is slidably connected to the support assembly 100. The base 211 is provided with a plurality of third through holes 2111. Each third through hole 2111 is located in the area enclosed by the second baffle ring 212, and each third through hole 2111 forms a third air duct 2001.

[0140] Multiple fourth through holes 2121 are provided on the second baffle ring 212. Each fourth through hole 2121 is spaced around the periphery of the second baffle ring 212, and each fourth through hole 2121 forms a fourth air duct 2002.

[0141] For example, the second retaining ring 212 can be sleeved on the outside of the mounting sleeve 111 of the fixed base 110, and the base 211 and the support plate 121 of the support member 120 can be arranged opposite to each other.

[0142] When the air duct switching assembly 200 moves toward the support assembly 100, the base 211 can close the first air duct 1001 on the support plate 121, and the fourth air duct 2002 on the second retaining ring 212 can connect with the second air duct 1002 on the mounting sleeve 111. At this time, the air duct switching assembly 200 is in the second state. When the air duct switching assembly 200 moves away from the support assembly 100, the base 211 opens the first air duct 1001 on the support plate 121, so that the first air duct 1001 can connect with the third air duct 2001 on the base 211, and the second retaining ring 212 closes the second air duct 1002 on the mounting sleeve 111. At this time, the air duct switching assembly 200 is in the first state.

[0143] It should be understood that forming a third air duct 2001 through multiple third through holes 2111 and forming a fourth air duct 2002 through multiple fourth through holes 2121 can provide more flow paths for airflow and increase the intake volume, which will not be elaborated further here.

[0144] Reference Figure 2, Figure 4 and Figure 5 As shown, in some embodiments, a first closure member 220 is provided on the base 211, and the first closure member 220 is located in the area enclosed by the second retaining ring 212.

[0145] In the first state, the first sealing member 220 opens the first air duct 1001; in the second state, the first sealing member 220 closes the first air duct 1001.

[0146] The base 211 and the support plate 121 of the support member 120 can be arranged opposite to each other. The first sealing member 220 is disposed on the base 211. When the air duct switching component 200 moves toward the support member 100, the first sealing member 220 gradually blocks the first air duct 1001, so that the air duct switching component 200 is in the second state. When the air duct switching component 200 moves away from the support member 100, the first sealing member 220 gradually moves away from the first air duct 1001, opening the first air duct 1001, so that the first air duct 1001 is connected to the third air duct 2001 on the base 211, and the air duct switching component 200 is in the first state.

[0147] Reference Figure 2 and Figure 4 As shown, in some embodiments, the first sealing member 220 is a plug, which is inserted into the first air duct 1001 to seal the first air duct 1001.

[0148] In this way, the plug is inserted into the first air duct 1001, which is simple and compact, making it easy to open or block the first air duct 1001.

[0149] For example, the number of plugs can be multiple, such as two, three, four, five, six, seven, eight, etc., as long as the number of plugs corresponds to the number of second through holes 1211 forming the first air duct 1001. This application embodiment does not impose too many restrictions.

[0150] Reference Figure 4 As shown, in some embodiments, the air duct switching assembly 200 further includes a second seal 221.

[0151] The second sealing element 221 is fitted onto the plug to seal the gap between the plug and the first air duct 1001.

[0152] In this way, by sealing the gap between the second seal 221 and the first air duct 1001, the airflow is prevented from leaking through the first air duct 1001 when the air duct switching assembly 200 is in the second state.

[0153] For example, the second seal 221 can be a silicone part, a rubber part, or other sealing material with a certain elasticity. This application embodiment does not specifically limit this.

[0154] Reference Figure 4 As shown, in some embodiments, the second seal 221 is a conical seal ring, and the plug has a conical head that matches the inner ring of the conical seal ring, with the conical seal ring fitted onto the conical head.

[0155] The conical head has a conical guide portion, which is positioned toward the second through hole 1211 on the support plate 121. In this way, when the plunger moves toward the second through hole 1211, the conical guide portion can guide the plunger to be inserted into the second through hole 1211 to avoid jamming.

[0156] Reference Figure 2 and Figure 4 As shown, in some embodiments, the second retaining ring 212 has at least one second connecting portion 2122 for sliding connection with the support assembly 100.

[0157] And / or, the second retaining ring 212 has at least one second guide portion 2123 for sliding connection with the support assembly 100.

[0158] The second connecting part 2122 can be slidably connected to the first connecting part 112 on the fixed base 110, so as to realize the sliding of the air duct switching component 200 relative to the support component 100.

[0159] Furthermore, the second guide portion 2123 can be slidably connected to the first guide portion 113 on the fixed base 110, thereby guiding the sliding path of the air duct switching assembly 200.

[0160] For example, there is at least one second connecting part 2122. The number of second connecting parts 2122 can be one or more, as long as the number of second connecting parts 2122 is the same as the number of first connecting parts 112. This application embodiment does not impose too many restrictions on this.

[0161] For example, there is at least one second guide portion 2123. The number of second guide portions 2123 can be one or more, as long as the number of second guide portions 2123 is the same as the number of first guide portions 113. This application embodiment does not impose too many restrictions on this.

[0162] Reference Figure 4 As shown, in some embodiments, the second connecting portion 2122 is a limiting hole.

[0163] And / or, the second guide portion 2123 is a guide hole.

[0164] The second connecting part 2122 is a limiting hole, which corresponds to the limiting rod of the first connecting part 112 to limit the air duct switching assembly 200 to the limiting rod. The second guiding part 2123 is a guide hole, which corresponds to the guide rod of the first guiding part 113 to play a guiding role.

[0165] Reference Figure 4 As shown, in some embodiments, the air duct switching assembly 200 further includes a second closure 230, which is disposed between the second baffle ring 212 and the support assembly 100, and the fourth air duct 2002 is located between the second closure 230 and the third air duct 2001.

[0166] In the first state, the second sealing member 230 closes the second air duct 1002; in the second state, the second sealing member 230 opens the second air duct 1002.

[0167] For example, the second closure 230 may be disposed between the second retaining ring 212 and the mounting sleeve 111 of the fixing seat 110.

[0168] Thus, when the air duct switching component 200 moves away from the support component 100, the second air duct 1002 can be closed by the second sealing member 230, so that the air duct switching component 200 is in the first state. When the air duct switching component 200 moves toward the support component 100, the second sealing member 230 opens the second air duct 1002, so that the second air duct 1002 is connected to the fourth air duct 2002 on the second baffle ring 212, and the air duct switching component 200 is in the second state.

[0169] Thus, the second air duct 1002 can be closed or opened by the second sealing component 230.

[0170] Among them, refer to 6. Figure 9 and Figure 13 As shown, the fourth air duct 2002 is located between the second sealing member 230 and the third air duct 2001 to prevent the second sealing member 230 from blocking the fourth air duct 2002 and the third air duct 2001 during operation.

[0171] Reference Figures 4 to 12 As shown, in some embodiments, the second closure 230 includes a first sealing joint 231, an elastic member 232, and a second sealing joint 233 connected in sequence.

[0172] The first sealing joint 231 is sleeved on the support assembly 100, the second sealing joint 233 is inserted on the movable part 210, and the elastic part 232 is located between the first sealing joint 231 and the second sealing joint 233.

[0173] In the first state, the elastic element 232 seals the second air duct 1002; in the second state, the elastic element 232 is compressed to open the second air duct 1002.

[0174] For example, the first sealing joint 231 can be sleeved on the outside of the mounting sleeve 111 of the support assembly 100, and the second sealing joint 233 can be inserted into the inside of the second retaining ring 212 of the movable member 210.

[0175] Thus, in the first state of the air duct switching assembly 200, the elastic element 232 is in a naturally extended state, thereby sealing the second air duct 1002. When the air duct switching assembly 200 switches from the first state to the second state, the air duct switching assembly 200 moves toward the support assembly 100, thereby driving the second sealing joint 233 to move toward the first sealing joint 231, thereby compressing the elastic element 232, so that the elastic element 232 opens the second air duct 1002, allowing the second air duct 1002 to connect with the second air duct 1002 on the second retaining ring 212.

[0176] When the air duct switching component 200 switches from the second state to the first state, the air duct switching component 200 drives the second sealing joint 233 to move away from the first sealing joint 231, and the elastic element 232 returns to its original state to reseal the second air duct 1002.

[0177] In this way, the elastic element 232 can be extended or compressed by changing the relative positional relationship between the first sealing joint 231 and the second sealing joint 233, thereby sealing or opening the second air duct 1002.

[0178] For example, the elastic element 232 can be a silicone element, a rubber element, or other sealing material with a certain degree of elasticity. This application embodiment does not specifically limit this.

[0179] Reference Figure 2 , Figure 3 , Figure 6 and Figure 9 As shown, in some embodiments, the air duct structure 101 provided in this application further includes a reset member 300.

[0180] The air duct switching component 200 is connected to the support component 100 through the reset component 300, and the reset component 300 drives the air duct switching component 200 to switch from the second state to the first state.

[0181] It should be understood that the reset element 300 has a natural state and an energy-storing state. In the first state of the air duct switching assembly 200, the reset element 300 is in the natural state. In the second state of the air duct switching assembly 200, the reset element 300 is in the energy-storing state. When the air duct switching assembly 200 switches from the second state to the first state, the reset element 300 releases the energy stored in the energy-storing state, enabling the air duct switching assembly 200 to quickly switch to the first state.

[0182] The aforementioned energy storage state can be either compressed or stretched, and this application embodiment does not specifically limit this.

[0183] Furthermore, a locking structure is provided between the air duct switching component 200 and the support component 100. When the air duct switching component 200 is in the second state, the locking structure locks and limits the air duct switching component 200 and the support component 100. After the locking structure releases the restriction on the air duct switching component 200, the air duct switching component 200 can quickly switch to the first state under the action of the reset component 300.

[0184] Specifically, refer to Figure 6 and Figure 8 As shown, the reset member 300 can be sleeved between the first connecting part 112 and the second connecting part 2122.

[0185] For example, the reset component 300 can be a reset spring, a reset elastic sleeve, or other material with a certain elasticity. This application embodiment does not specifically limit this.

[0186] Reference Figure 1 and Figure 2 As shown, the cleaning device 10 provided in this application includes a device body and the air duct structure 101 as described above, with the air duct structure 101 disposed within the device body.

[0187] The cleaning equipment 10 also includes a motor assembly 102 and a dust cup assembly 103. The motor assembly 102 is disposed in the equipment body and is connected to the air duct structure 101. The dust cup assembly 103 is disposed on the equipment body and the air duct structure 101 is located between the motor assembly 102 and the dust cup assembly 103.

[0188] Thus, by moving the air duct switching component 200 relative to the support component 100 through the air duct structure 101, the air duct switching component 200 switches between a first state and a second state. In the first state, the dust cup assembly 103 and the motor assembly 102 can be connected through the first air duct 1001 and the third air duct 2001 of the air duct switching component 200, and the motor assembly 102 provides suction force to collect debris on the surface to be cleaned into the dust cup assembly 103.

[0189] The cleaning system provided in this application includes a base station 20 and a cleaning device 10 as described above. The base station 20 is used to collect debris from the dust cup assembly 103 of the cleaning device 10.

[0190] It should be understood that the base station 20 in the cleaning system has a dust collection chamber 201 and an air duct 202, and the dust collection chamber 201 is connected to the air duct 202.

[0191] Thus, in the second state, the air duct 202 of the base station 20 and the motor assembly 102 of the cleaning device 10 can be connected through the second air duct 1002 and the fourth air duct 2002. The motor assembly 102 provides suction to collect debris in the dust cup assembly 103 of the cleaning device 10 into the dust collection chamber 201 of the base station 20.

[0192] 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.
