Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and in particular, to an air duct structure, a cleaning device, and a cleaning system. Background Art

[0002] With the improvement of living standards, people have higher requirements for the quality of the living environment, and household dust removal devices such as cleaning devices (such as vacuum cleaners, floor washers, etc.) appear more and more in people's lives.

[0003] In the related art, 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 provided on the device body. The dust cup has an openable and closable end cover. When the device body is working, it can suck the sundries on the surface to be cleaned into the dust cup. When the base station is connected to the device body, it can open the end cover and then clean the sundries in the dust cup through the self-collecting dust program of the base station.

[0004] However, in this way, the base station also needs to be provided with an independent suction motor, resulting in a higher cost of the cleaning system. Summary of the Invention

[0005] The present application provides an air duct structure, a cleaning device, and a cleaning system to solve the problem that independent suction motors need to be provided in both the base station and the handheld device, resulting in a higher cost of the cleaning device.

[0006] In a first aspect, the air duct structure provided by the present application includes:

[0007] A support component for connecting with the motor component of the cleaning device. The support component is provided with a first air duct and a second air duct for communicating with the motor component, and a first connecting portion is provided on the support component;

[0008] An air duct switching component having a third air duct, a fourth air duct, and a second connecting portion. The third air duct is used for communicating with the dust cup component of the cleaning device. The first connecting portion is slidably connected to the second connecting portion so that the air duct switching component can move relative to the support component and switch between a first state and a second state;

[0009] In the first state, the first air duct is communicated with the third air duct, and the second air duct and the fourth air duct are closed, so that the dust cup component and the motor component are communicated; in the second state, the first air duct and the third air duct are closed, and the second air duct is communicated with the fourth air duct; when the second air duct is communicated with the fourth air duct, the dust cup component, the base station, the fourth air duct, the second air duct, and the motor component are communicated in sequence, so that the base station can collect the sundries in the dust cup component.

[0010] In this way, by moving the air duct switching component relative to the support component, the air duct switching component is switched between the first state and the second state. In the first state, the dust cup component is communicated with the motor component, and the motor component provides a suction force to collect the sundries on the surface to be cleaned into the dust cup component. In the second state, the motor component is communicated with the base station, and the motor component provides a suction force to collect the sundries in the dust cup component into the dust collection chamber of the base station. In this way, the entire cleaning system only needs one motor component to operate, so as to reduce the cost.

[0011] In a possible implementation manner, for the air duct structure provided by the present application, the support component includes:

[0012] A fixed seat, which is used to connect with the motor component, and the second air duct is arranged on the fixed seat;

[0013] A support member, which is arranged on the fixed seat, and the first air duct is located on the support member;

[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] In this way, the first air duct and the second air duct are separately arranged to avoid the situation that the first air duct and the second air duct are misaligned and docked when the air duct switching component is switched, which affects the user experience.

[0016] In a possible implementation manner, for the air duct structure provided by the present application, the fixed seat is provided with an installation sleeve, and the support member is inserted into the installation sleeve;

[0017] The installation sleeve is provided with a plurality of first through holes, and the first through holes are arranged at intervals around the circumferential side of the installation sleeve, and each first through hole forms the second air duct.

[0018] In this way, the second air duct is formed by a plurality of first through holes arranged at intervals around the circumferential side of the installation sleeve, which can provide more flow paths for the air flow, increase the air intake, and accelerate the flow rate of the air flow, so as to improve the suction efficiency of the motor component.

[0019] In a possible implementation manner, for the air duct structure provided by the present application, the fixed seat is provided with at least one first guiding portion, and the first guiding portion is used for slidably connecting with the air duct switching component.

[0020] In this way, the air duct switching component is switched between the first state and the second state in a sliding manner, which is convenient for the user to perform the switching operation. Moreover, the sliding path of the air duct switching component is guided by the first guiding portion to avoid the air duct switching component deviating from the sliding path, resulting in the inability to accurately close the first air duct or the second air duct.

[0021] In a possible implementation, for the air duct structure provided by the present application, the first connecting portion is a limiting rod;

[0022] And / or, the first guiding portion is a guiding column.

[0023] In this way, the air duct switching component can slide relative to the limiting rod and be limited on the limiting rod to prevent the air duct switching component from falling off the limiting rod. The guiding column is used to guide the air duct switching component to slide along a specified sliding path to prevent the air duct switching component from deviating from the sliding path.

[0024] In a possible implementation, for the air duct structure provided by the present application, the support member includes a support plate and a first retaining ring provided on the support plate. The support plate has a plurality of second through holes, and each second through hole is located within the area enclosed by the first retaining ring. The plurality of second through holes together form a first air duct.

[0025] In this way, the support member can be inserted into the installation sleeve of the fixed seat through the first retaining ring, which facilitates the corresponding installation of the support member and the fixed seat. Moreover, the first air duct is formed by a plurality of second through holes together, which can provide more flow paths for the air flow, increase the air intake volume, and accelerate the flow rate of the air flow to improve the suction efficiency of the motor assembly.

[0026] In a possible implementation, for the air duct structure provided by the present application, the support assembly further includes a first sealing member;

[0027] The first sealing member is sleeved on the support member and abuts between the installation sleeve and the support member;

[0028] Part of the support assembly is located within the air duct switching component, and one end of the first sealing member facing away from the support assembly abuts against the air duct switching component to seal the gap between the air duct switching component and the support assembly.

[0029] In this way, the gap between the installation sleeve and the support member is sealed by the first sealing member to prevent the air flow from leaking through the gap between the installation sleeve and the support member. Moreover, the gap between the air duct switching component and the support assembly is sealed by the first sealing member to prevent the air flow from leaking.

[0030] In a possible implementation, for the air duct structure provided by the present application, the air duct switching component includes a movable member;

[0031] The movable member includes a base and a second retaining ring provided on the base;

[0032] The second retaining ring is slidably connected to the support assembly. The base is provided with a plurality of third through holes, and each third through hole is located within the area enclosed by the second retaining ring. The plurality of third through holes form a third air duct;

[0033] A plurality of fourth through holes are provided on the second retaining ring, and the fourth through holes are arranged at intervals around the circumferential side of the second retaining ring, and each fourth through hole forms a fourth air duct.

[0034] In this way, when the air duct switching component moves towards the support component, the first air duct on the support plate can be closed by the base, and the fourth air duct on the second retaining ring can be communicated with the second air duct on the mounting sleeve. When the air duct switching component moves away from the support component, the base opens the first air duct on the support plate to communicate the first air duct with the third air duct on the base, and the second retaining ring closes the second air duct on the mounting sleeve.

[0035] In a possible implementation manner, for the air duct structure provided in the present application, a first closing member is provided on the base, and the first closing member is located within the area surrounded by the second retaining ring;

[0036] In the first state, the first closing member opens the first air duct; in the second state, the first closing member closes the first air duct.

[0037] In this way, when the air duct switching component moves towards the support component, the first air duct can be blocked by the first closing member. When the air duct switching component moves away from the support component, the first closing member opens the first air duct.

[0038] In a possible implementation manner, for the air duct structure provided in the present application, the first closing member is a plug post, and the plug post is correspondingly inserted into the first air duct to close the first air duct.

[0039] In this way, the structure is simple and compact, which is convenient for opening or blocking the first air duct.

[0040] In a possible implementation manner, for the air duct structure provided in the present application, the air duct switching component further includes a second sealing member;

[0041] The second sealing member is sleeved on the plug post to seal the gap between the plug post and the first air duct.

[0042] In this way, the gap between the plug post and the first air duct is sealed by the second sealing member, so as to prevent air leakage through the first air duct when the air duct switching component is in the second state.

[0043] In a possible implementation manner, for the air duct structure provided in the present application, the second sealing member is a conical sealing ring, and the plug post has a conical head matching the inner ring of the conical sealing ring, and the conical sealing ring is sleeved on the conical head.

[0044] In this way, when the plug post moves towards the second through hole, the plug post can be guided by the conical head to be correspondingly inserted into the second through hole to avoid jamming.

[0045] In a possible implementation, for the air duct structure provided by the present application, there is at least one second guiding portion on the second retaining ring, and the second guiding portion is used for sliding connection with the support assembly.

[0046] In this way, the air duct switching assembly can slide relative to the support assembly, and play a guiding role in the sliding path of the air duct switching assembly.

[0047] In a possible implementation, for the air duct structure provided by the present application, the second connecting portion is a limiting hole;

[0048] And / or, the second guiding portion is a guiding hole.

[0049] In this way, the limiting hole can correspond to the limiting rod of the first connecting portion to limit the air duct switching assembly to the limiting rod. The guiding hole can correspond to the guiding rod of the first guiding portion to play a guiding role.

[0050] In a possible implementation, for the air duct structure provided by the present application, the air duct switching assembly further includes a second sealing member, and the second sealing member is disposed between the second retaining ring and the support assembly, and the fourth air duct is located between the second sealing member and the third air duct;

[0051] In the first state, the second sealing member closes the second air duct; in the second state, the second sealing member opens the second air duct.

[0052] In this way, the second air duct can be closed and opened through the second sealing member.

[0053] In a possible implementation, for the air duct structure provided by the present application, the second sealing member includes a first sealing joint, an elastic member and a second sealing joint connected in sequence;

[0054] The first sealing joint is sleeved on the support assembly, the second sealing joint is inserted on the movable member, and the elastic member is located between the first sealing joint and the second sealing joint;

[0055] In the first state, the elastic member seals the second air duct; in the second state, the elastic member is compressed to open the second air duct.

[0056] In this way, the relative position relationship between the first sealing joint and the second sealing joint can be changed to stretch or compress the elastic member, so as to seal or open the second air duct.

[0057] In a possible implementation, for the air duct structure provided by the present application, it further includes a reset member;

[0058] The air duct switching assembly is connected to the support assembly through the reset member, and the reset member drives the air duct switching assembly to switch from the second state to the first state.

[0059] In this way, the air duct switching assembly can be quickly switched from the second state to the first state by the reset member.

[0060] In a second aspect, the cleaning device provided by the present application includes a device body and the air duct structure as described above, and the air duct structure is arranged in the device body.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall 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.

[0089] In the description of this application, it should be noted that, unless otherwise clearly specified and defined, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0090] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0091] In the description of the present application, the claims, and the above-mentioned drawings, the terms "first", "second", "third" (if any) are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order different from those illustrated or described herein, for example.

[0092] In addition, the terms "comprising", "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0093] In the related art, 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 provided on the device body. The dust cup has an openable and closable end cap. When the device body is working, it can suck the sundries on the surface to be cleaned into the dust cup, and when the base station is connected to the device body, it can open the end cap and then clean the sundries in the dust cup through the self-dust collection program of the base station.

[0094] However, such a base station also needs to be provided with an independent suction motor, resulting in a relatively high cost of the cleaning system.

[0095] In view of the above problems, the present 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 is provided with a first air duct and a second air duct for communicating with a motor assembly. 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 device. The air duct switching assembly is connected to the support assembly and moves 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 in communication, and the motor assembly provides a suction force to collect the sundries on the surface to be cleaned into the dust cup assembly. In the second state, the motor assembly is in communication with the base station, and the motor assembly provides a suction force to collect the sundries in 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, so as to reduce the cost.

[0096] The following will describe in detail the specific implementation manners of the air duct structure, the cleaning device, and the cleaning system provided by the embodiments of the present application with reference to the accompanying drawings.

[0097] It should be noted that the air duct structure provided in this application can be applied to various different cleaning devices. Specifically, when implemented, the cleaning device includes a dust cup assembly and a motor assembly. The motor assembly is used to provide suction force to collect the debris on the surface to be cleaned into the dust cup assembly. Moreover, this cleaning device can be applied to various different cleaning systems. The cleaning system includes this cleaning device and a base station. The base station can open the dust cup assembly of the cleaning device and communicate with the dust cup assembly to collect the debris in the dust cup assembly.

[0098] Referring to Figure 1 and Figure 2 As shown, the air duct structure 101 provided in this application includes a support assembly 100 and an air duct switching assembly 200.

[0099] The support assembly 100 is used to connect with the motor assembly 102 of the cleaning device 10. A first air duct 1001 and a second air duct 1002 for communicating with the motor assembly 102 are provided on the support assembly 100, and a first connecting portion 112 is provided on the support assembly 100.

[0100] The air duct switching assembly 200 has a third air duct 2001, a fourth air duct 2002 and a second connecting portion 2122. The third air duct 2001 is used to communicate with the dust cup assembly 103 of the cleaning device 10. The first connecting portion 112 is slidably connected to the second connecting portion 2122 so that the air duct switching assembly 200 moves relative to the support assembly 100 and switches between a first state and a second state;

[0101] In the first state, the first air duct 1001 communicates with 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 communicate. In the second state, the first air duct 1001 and the third air duct 2001 are closed, and the second air duct 1002 communicates with the fourth air duct 2002; when the second air duct 1002 communicates with the fourth air duct 2002, 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 the debris in the dust cup assembly 103.

[0102] It can be understood that the air duct structure 101 provided in this application can be disposed inside the cleaning device 10, and the cleaning device 10 has a dust cup assembly 103, and the dust cup assembly 103 has a dust collection port and an end cover. When the cleaning device 10 cleans the surface to be cleaned, the user can switch the air duct switching assembly 200 to the first state. At this time, the first air duct 1001 communicates with the third air duct 2001, and the second air duct 1002 and the fourth air duct 2002 are in a closed state, so that the dust cup assembly 103 and the motor assembly 102 communicate. Referring to Figures 5 to 8As shown, the motor assembly 102 provides a suction force. The air flow enters the dust cup assembly 103 from the dust collection port, then successively flows through the third air duct 2001, the first air duct 1001, and the motor assembly 102, and finally is discharged from the exhaust hole on the dust cup assembly 103, so as to collect the sundries on the surface to be cleaned through the dust collection port of the dust cup assembly 103.

[0103] In addition, it should be understood that the base station 20 in the cleaning system has a dust collection chamber 201 and an air guiding channel 202, and the dust collection chamber 201 is communicated with the air guiding channel 202. When the cleaning device 10 is docked with the base station 20, the base station 20 can open the end cover of the dust cup assembly 103 to make the dust cup assembly 103 communicate with the dust collection chamber 201, and the air guiding channel 202 can be used to communicate with the second air duct 1002 and the fourth air duct 2002.

[0104] In this way, the user can switch the air duct switching assembly 200 to the second state. At this time, the first air duct 1001 and the third air duct 2001 are in a closed state to close the dust cup assembly 103 and the motor assembly 102; the second air duct 1002 is communicated with the fourth air duct 2002, so that the air guiding channel 202, the fourth air duct 2002, the second air duct 1002, and the motor assembly 102 of the base station 20 are successively communicated. Refer to Figures 8 to 14 As shown, due to the suction force provided by the motor assembly 102, the air flow enters the dust cup assembly 103 from the dust collection port, then successively flows through the dust collection chamber 201, the air guiding channel 202, the fourth air duct 2002, the second air duct 1002, and the motor assembly 102, and finally is discharged from the exhaust hole on the dust cup assembly 103, so as to collect the sundries in the dust cup assembly 103 into the dust collection chamber 201 of the base station 20.

[0105] Of course, in some other embodiments, an air inlet can also be separately provided on the dust cup assembly 103. When collecting the sundries in the dust cup assembly 103 through the base station 20, the air flow enters the dust cup assembly 103 from the air inlet, and the embodiments of the present application do not make specific limitations on this.

[0106] The air duct structure 101 provided by the present application enables the air duct switching assembly 200 to switch between the first state and the second state by moving the air duct switching assembly 200 relative to the support assembly 100. In the first state, the dust cup assembly 103 and the motor assembly 102 are communicated, and the motor assembly 102 provides a suction force to collect the sundries on the surface to be cleaned into the dust cup assembly 103. In the second state, the motor assembly 102 is communicated with the base station 20, and the motor assembly 102 provides a suction force to collect the sundries in the dust cup assembly 103 into the dust collection chamber 201 of the base station 20. In this way, the entire cleaning system can operate with only one motor assembly 102, so as to reduce the cost.

[0107] Refer to Figure 2 and Figure 3As shown, in some embodiments, the support assembly 100 includes a fixed seat 110 and a support member 120.

[0108] The fixed seat 110 is used to connect with the motor assembly 102, and the second air duct 1002 is arranged on the fixed seat 110. The support member 120 is arranged on the fixed seat 110, and the first air duct 1001 is located on the support member 120.

[0109] In the first state, the air duct switching assembly 200 opens the first air duct 1001 and closes the second air duct 1002; in the second state, the air duct switching assembly 200 closes the first air duct 1001 and opens the second air duct 1002.

[0110] It can be understood that both the first air duct 1001 and the second air duct 1002 are used to communicate with the motor assembly 102. In the first state, the air duct switching assembly 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 assembly 200, and the dust cup assembly 103 are connected in sequence. In the second state, the air duct switching assembly 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 assembly 200, and the air guiding channel 202 of the base station 20 are connected in sequence.

[0111] In this way, the first air duct 1001 is arranged on the support member 120, and the second air duct 1002 is arranged on the fixed seat 110, so as to separately arrange the first air duct 1001 and the second air duct 1002, avoiding the situation of misaligned docking between the first air duct 1001 and the second air duct 1002 when the air duct switching assembly 200 switches, for example, the first air duct 1001 is docked with the fourth air duct 2002, and the second air duct 1002 is docked with the third air duct 2001, which affects the user experience.

[0112] Refer to Figure 2 and Figure 3 As shown, in some embodiments, the fixed seat 110 has a mounting sleeve 111, and the support member 120 is inserted into the mounting sleeve 111.

[0113] A plurality of first through holes 1111 are arranged on the mounting sleeve 111, and the first through holes 1111 are spaced at intervals around the circumferential side of the mounting sleeve 111, and the first through holes 1111 form the second air duct 1002.

[0114] Among them, the support member 120 is inserted into the mounting sleeve 111, so that the structure is simple and compact, and the support member 120 can be conveniently inserted and assembled with the fixed seat 110.

[0115] The second air duct 1002 is formed by a plurality of first through holes 1111 arranged at intervals around the circumferential side of the mounting sleeve 111. In this way, in the second state of the air duct switching assembly 200, more flow paths can be provided for the air flow, the air intake can be increased, and the flow rate of the air flow can be accelerated to improve the suction efficiency of the motor assembly 102.

[0116] Exemplarily, the shape of the first through hole 1111 can be circular, elliptical, square, triangular, etc., and the embodiments of the present application do not make specific limitations thereto.

[0117] Referring to Figure 2 and Figure 3 As shown, in some embodiments, the fixed seat 110 has at least one first guiding portion 113, and the first guiding portion 113 is used for slidably connecting with the air duct switching assembly 200.

[0118] In this way, the air duct switching assembly 200 can be slidably arranged on the first connecting portion 112, so that the air duct switching assembly 200 can be switched between the first state and the second state by sliding, which is convenient for the user to perform the switching operation.

[0119] The first guiding portion 113 is slidably connected with the air duct switching assembly 200. The first guiding portion 113 guides the air duct switching assembly 200 to slide along a specified sliding path, avoiding the air duct switching assembly 200 deviating from the sliding path, resulting in the inability to accurately close the first air duct 1001 or the second air duct 1002.

[0120] Specifically, the first connecting portion 112 can be arranged on the fixed seat 110.

[0121] It can be understood that there is at least one first connecting portion 112, and the number of the first connecting portions 112 can be one or more. The embodiments of the present application do not make excessive limitations thereto.

[0122] It can be understood that there is at least one first guiding portion 113, and the number of the first guiding portions 113 can be one or more. The embodiments of the present application do not make excessive limitations thereto.

[0123] Referring to Figure 2 and Figure 3 As shown, in some embodiments, the first connecting portion 112 is a limiting rod.

[0124] And / or, the first guiding portion 113 is a guiding column.

[0125] Wherein, a limiting portion may be provided at an end of the limiting rod facing away from the fixed seat 110, so that the air duct switching assembly 200 can slide relative to the limiting rod, and the air duct switching assembly 200 is limited on the limiting rod by the limiting portion of the limiting rod, preventing the air duct switching assembly 200 from falling off the limiting rod. The guiding column 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.

[0126] Referring 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 provided on the support plate 121. The support plate 121 has a plurality of second through holes 1211, and each of the second through holes 1211 is located within the area enclosed by the first retaining ring 122. The second through holes 1211 together form the first air duct 1001.

[0127] It can be understood that the support member 120 can be inserted into the mounting sleeve 111 of the fixed seat 110 through the first retaining ring 122, which facilitates the corresponding installation of the support member 120 and the fixed seat 110. Wherein, a buckle portion may be provided on the outer side of the first retaining ring 122, and a clamping groove adapted to the buckle portion may be provided on the inner side of the mounting sleeve 111. The support member 120 and the fixed seat 110 are assembled by corresponding clamping of the buckle portion and the clamping groove.

[0128] The first air duct 1001 is jointly formed by a plurality of second through holes 1211. In this way, in the first state of the air duct switching assembly 200, more flow paths can be provided for the air flow, increasing the intake air volume and accelerating the flow rate of the air flow, so as to improve the suction efficiency of the motor assembly 102.

[0129] Referring Figure 2 and Figure 3 As shown, in some embodiments, the support assembly 100 further includes a first seal 130.

[0130] The first seal 130 is sleeved on the support member 120 and abuts between the mounting sleeve 111 and the support member 120.

[0131] Part of the support assembly 100 is located within the air duct switching assembly 200, and one end of the first seal 130 facing away from the support assembly 100 abuts against the air duct switching assembly 200 to seal the gap between the air duct switching assembly 200 and the support assembly 100.

[0132] Exemplarily, the first seal 130 may be provided 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, preventing the air flow from leaking through the gap between the mounting sleeve 111 and the support member 120.

[0133] Furthermore, referring to Figure 3 、 Figure 4 and Figure 5 As shown, the support member 120 is inserted into the mounting sleeve 111 of the fixed seat 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. Among them, the air duct switching assembly 200 moves towards the support assembly 100, which can close the first air duct 1001 and open the second air duct 1002. At this time, it is in the second state of the air duct switching assembly 200. The air duct switching assembly 200 moves away from the support assembly 100, which can open the first air duct 1001 and close the second air duct 1002. At this time, it is in the first state of the air duct switching assembly 200.

[0134] Since part of the support assembly 100 is located inside the air duct switching assembly 200, an active clearance needs to be left between the support assembly 100 and the air duct switching assembly 200 to enable the air duct switching assembly 200 to slide relative to the support assembly 100. The active clearance is sealed by the first seal 130 to prevent air leakage.

[0135] Exemplarily, the first seal 130 can be a silicone part, a rubber part, or other sealing materials with certain elasticity. The embodiments of the present application do not make specific limitations on this.

[0136] Referring to Figure 2 and Figure 4 As shown, in some embodiments, the air duct switching assembly 200 includes a movable member 210. The movable member 210 includes a base 211 and a second retaining ring 212 provided on the base 211.

[0137] The second retaining ring 212 is slidably connected to the support assembly 100. A plurality of third through holes 2111 are provided on the base 211. Each of the third through holes 2111 is located within the area surrounded by the second retaining ring 212. Each of the third through holes 2111 forms a third air duct 2001.

[0138] A plurality of fourth through holes 2121 are provided on the second retaining ring 212. Each of the fourth through holes 2121 is spaced around the circumferential side of the second retaining ring 212. Each of the fourth through holes 2121 forms a fourth air duct 2002.

[0139] Exemplarily, the second retaining ring 212 can be sleeved on the outside of the mounting sleeve 111 of the fixed seat 110, and the base 211 and the support plate 121 of the support member 120 can be oppositely arranged.

[0140] In this way, when the air duct switching component 200 moves towards the support component 100, the first air duct 1001 on the support plate 121 can be closed by the base 211, and the fourth air duct 2002 on the second retaining ring 212 can be communicated with the second air duct 1002 on the mounting sleeve 111. At this time, the air duct switching component 200 is in the second state. When the air duct switching component 200 moves away from the support component 100, the base 211 opens the first air duct 1001 on the support plate 121 to communicate the first air duct 1001 with the third air duct 2001 on the base 211. Moreover, the second retaining ring 212 closes the second air duct 1002 on the mounting sleeve 111. At this time, the air duct switching component 200 is in the first state.

[0141] It should be understood that the third air duct 2001 is formed by a plurality of third through holes 2111, and the fourth air duct 2002 is formed by a plurality of fourth through holes 2121, both of which can provide more flow paths for the air flow and increase the air intake volume, and will not be elaborated here.

[0142] Refer to Figure 2 、 Figure 4 and Figure 5 As shown in

[0143] In the first state, the first closing member 220 opens the first air duct 1001; in the second state, the first closing member 220 closes the first air duct 1001.

[0144] Among them, the base 211 and the support plate 121 of the support member 120 can be relatively arranged. The first closing member 220 is arranged on the base 211. When the air duct switching component 200 moves towards the support component 100, the first closing 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 component 100, the first closing member 220 gradually moves away from the first air duct 1001 to open the first air duct 1001, so that the first air duct 1001 is communicated with the third air duct 2001 on the base 211, and the air duct switching component 200 is in the first state.

[0145] Refer to Figure 2 and Figure 4 As shown in

[0146] In this way, by correspondingly inserting the plug post into the first air duct 1001, the structure is simple and compact, which is convenient to open or block the first air duct 1001.

[0147] Exemplarily, the number of the plug columns can be multiple, such as two, three, four, five, six, seven, eight, etc., as long as the number of the plug columns corresponds to the number of the second through holes 1211 forming the first air duct 1001. The embodiments of the present application do not have excessive restrictions.

[0148] Referring Figure 4 As shown, in some embodiments, the air duct switching assembly 200 further includes a second seal 221.

[0149] The second seal 221 is sleeved on the plug column to seal the gap between the plug column and the first air duct 1001.

[0150] In this way, by sealing the gap between the plug column and the first air duct 1001 through the second seal 221, it is avoided that when the air duct switching assembly 200 is in the second state, the air flow leaks through the first air duct 1001.

[0151] Exemplarily, the second seal 221 can be a silicone part, a rubber part or other sealing materials with certain elasticity. The embodiments of the present application do not make specific limitations thereto.

[0152] Referring Figure 4 As shown, in some embodiments, the second seal 221 is a conical sealing ring, and the plug column has a conical head matching the inner ring of the conical sealing ring, and the conical sealing ring is sleeved on the conical head.

[0153] Wherein, the conical head has a conical guiding part, and the conical guiding part is arranged towards the second through hole 1211 on the support plate 121. In this way, when the plug column moves towards the second through hole 1211, the plug column can be guided by the conical guiding part to be correspondingly inserted into the second through hole 1211, so as to avoid jamming.

[0154] Referring Figure 2 and Figure 4 As shown, in some embodiments, the second retaining ring 212 has at least one second guiding part 2123, and the second guiding part 2123 is used for slidably connecting with the support assembly 100.

[0155] Wherein, the second connecting part 2122 can be correspondingly slidably connected with the first connecting part 112 on the fixed seat 110, so as to realize the sliding of the air duct switching assembly 200 relative to the support assembly 100.

[0156] Moreover, the second guiding part 2123 can be correspondingly slidably connected with the first guiding part 113 on the fixed seat 110, so as to play a guiding role in the sliding path of the air duct switching assembly 200.

[0157] Specifically, the second connecting part 2122 is arranged on the second retaining ring 212.

[0158] Exemplarily, there is at least one second connecting portion 2122. The number of the second connecting portions 2122 may be one or more, as long as the number of the second connecting portions 2122 is the same as that of the first connecting portion 112. The embodiments of the present application do not impose excessive restrictions thereon.

[0159] Exemplarily, there is at least one second guiding portion 2123. The number of the second guiding portions 2123 may be one or more, as long as the number of the second guiding portions 2123 is the same as that of the first guiding portion 113. The embodiments of the present application do not impose excessive restrictions thereon.

[0160] Referring to Figure 4 As shown, in some embodiments, the second connecting portion 2122 is a limiting hole.

[0161] And / or, the second guiding portion 2123 is a guiding hole.

[0162] Among them, the second connecting portion 2122 is a limiting hole, so that it can correspond to the limiting rod of the first connecting portion 112 to limit the air duct switching assembly 200 to the limiting rod. The second guiding portion 2123 is a guiding hole, so that it can correspond to the guiding rod of the first guiding portion 113 to play a guiding role.

[0163] Referring to Figure 4 As shown, in some embodiments, the air duct switching assembly 200 further includes a second sealing member 230. The second sealing member 230 is disposed between the second retaining ring 212 and the support assembly 100, and the fourth air duct 2002 is located between the second sealing member 230 and the third air duct 2001.

[0164] 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.

[0165] Exemplarily, the second sealing member 230 may be disposed between the second retaining ring 212 and the mounting sleeve 111 of the fixed seat 110.

[0166] In this way, when the air duct switching assembly 200 moves away from the support assembly 100, the second air duct 1002 can be closed by the second sealing member 230, so that the air duct switching assembly 200 is in the first state. When the air duct switching assembly 200 moves towards the support assembly 100, the second sealing member 230 opens the second air duct 1002, so that the second air duct 1002 communicates with the fourth air duct 2002 on the second retaining ring 212, and the air duct switching assembly 200 is in the second state.

[0167] In this way, the second air duct 1002 can be closed and opened by the second sealing member 230.

[0168] Among them, referring to 6, Figure 9and Figure 13 As shown, the fourth air duct 2002 is located between the second seal 230 and the third air duct 2001 to prevent the fourth air duct 2002 and the third air duct 2001 from being blocked during the operation of the second seal 230.

[0169] Referring Figures 4 to 12 As shown, in some embodiments, the second seal 230 includes a first sealing joint 231, an elastic member 232, and a second sealing joint 233 connected in sequence.

[0170] The first sealing joint 231 is sleeved on the support assembly 100, the second sealing joint 233 is inserted into the movable member 210, and the elastic member 232 is located between the first sealing joint 231 and the second sealing joint 233.

[0171] In the first state, the elastic member 232 seals the second air duct 1002; in the second state, the elastic member 232 is compressed to open the second air duct 1002.

[0172] Exemplarily, 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.

[0173] Thus, in the first state of the air duct switching assembly 200, the elastic member 232 is in a natural stretched state, thereby sealing the second air duct 1002. When the air duct switching assembly 200 is switched from the first state to the second state, the air duct switching assembly 200 moves towards the support assembly 100 to drive the second sealing joint 233 to move towards the first sealing joint 231, thereby compressing the elastic member 232 to open the second air duct 1002 and connect the second air duct 1002 on the second air duct 1002 with the second retaining ring 212.

[0174] When the air duct switching assembly 200 is switched from the second state to the first state, the air duct switching assembly 200 drives the second sealing joint 233 to move away from the first sealing joint 231, and the elastic member 232 is restored to reseal the second air duct 1002.

[0175] In this way, by changing the relative positional relationship between the first sealing joint 231 and the second sealing joint 233, the elastic member 232 can be stretched or compressed, thereby sealing or opening the second air duct 1002.

[0176] Exemplarily, the elastic member 232 can be a silica gel member, a rubber member, or other sealing materials with certain elasticity, and the embodiments of the present application do not make specific limitations on this.

[0177] Referring Figure 2 、 Figure 3 、 Figure 6and Figure 9 As shown, in some embodiments, the air duct structure 101 provided in the present application further includes a reset member 300.

[0178] The air duct switching assembly 200 is connected to the support assembly 100 through the reset member 300, and the reset member 300 drives the air duct switching assembly 200 to switch from the second state to the first state.

[0179] It should be understood that the reset member 300 has a natural state and an energy storage state. When the air duct switching assembly 200 is in the first state, the reset member 300 is in the natural state. When the air duct switching assembly 200 is in the second state, the reset member 300 is in the energy storage state. When the air duct switching assembly 200 switches from the second state to the first state, the reset member 300 releases the energy stored in the energy storage state, so that the air duct switching assembly 200 can quickly switch to the first state.

[0180] Among them, the above energy storage state can be compression or stretching, and the embodiments of the present application do not make specific limitations on this.

[0181] Furthermore, a locking structure is provided between the air duct switching assembly 200 and the support assembly 100. When the air duct switching assembly 200 is in the second state, the locking structure locks and limits the air duct switching assembly 200 and the support assembly 100. After the locking structure releases the restriction on the air duct switching assembly 200, the air duct switching assembly 200 can quickly switch to the first state under the action of the reset member 300.

[0182] Specifically, referring to Figure 6 and Figure 8 As shown, the reset member 300 can be sleeved between the first connecting portion 112 and the second connecting portion 2122.

[0183] Exemplarily, the reset member 300 can be a reset spring, a reset elastic sleeve or other materials with certain elasticity, and the embodiments of the present application do not make specific limitations on this.

[0184] Referring to Figure 1 and Figure 2 As shown, the cleaning device 10 provided in the present application includes a device body and the air duct structure 101 as above, and the air duct structure 101 is arranged in the device body.

[0185] Among them, the cleaning device 10 further includes a motor assembly 102 and a dust cup assembly 103. The motor assembly 102 is arranged in the device body, and the motor assembly 102 is connected to the air duct structure 101. The dust cup assembly 103 is arranged on the device body, and the air duct structure 101 is located between the motor assembly 102 and the dust cup assembly 103.

[0186] In this way, the air duct switching component 200 of the air duct structure 101 moves relative to the support component 100, and the air duct switching component 200 switches between the first state and the second state. In the first state, the dust cup component 103 and the motor component 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 component 102 provides a suction force to collect the sundries on the surface to be cleaned into the dust cup component 103.

[0187] The cleaning system provided by this application includes a base station 20 and the cleaning device 10 as above, and the base station 20 is used to collect the sundries in the dust cup component 103 of the cleaning device 10.

[0188] It should be understood that the base station 20 in the cleaning system has a dust collection chamber 201 and an air guiding channel 202, and the dust collection chamber 201 is communicated with the air guiding channel 202.

[0189] In this way, in the second state, the air guiding channel 202 of the base station 20 and the motor component 102 of the cleaning device 10 can be connected through the second air duct 1002 and the fourth air duct 2002, and the motor component 102 provides a suction force to collect the sundries in the dust cup component 103 of the cleaning device 10 into the dust collection chamber 201 of the base station 20.

[0190] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
