[0059] The technical solution provided by the present disclosure has the following beneficial effects:

[0060] The dust collector device provided by the present disclosure comprises a device main body, a dust cup assembly, a suction device and an air duct switching structure. The dust cup assembly, the suction device and the air duct switching structure are all arranged on the device main body. The dust cup assembly can be used to store the external dirt sucked into the dust collector device during the cleaning process, and the suction device is used to provide suction force. Moreover, the air duct switching structure has a first working state suitable for communicating the suction device and the dust collecting station, and a second working state suitable for communicating the suction device and the dust cup assembly, i.e. the suction device can be selectively communicated with the device main body and the dust collecting station.

[0079] The present disclosure provides a dust cleaner device 100, specifically, referring to FIG. 1 to FIG. 3, the dust cleaner device 100 comprises a device main body 2, a dust cup assembly 3, a suction device 4 and an air duct switching structure 1 arranged on the device main body 2, the device main body 2 is provided with a first air inlet 23 adapted to be connected with a dust collecting station 200, and a dust suction port 24; the air duct switching structure 1 is movably arranged on the device main body 2, the air duct switching structure 1 has a first working state adapted to connect the suction device 4 and the dust collecting station 200, and a second working state adapted to connect the suction device 4 and the dust cup assembly 3; when in the first working state, the air flow has a first flow path from the first air inlet 23, through the dust cup assembly 3, and then flows to the air inlet end of the suction device 4 through the air duct switching structure 1; when in the second working state, the air flow has a second flow path from the dust suction port 24, through the air duct switching structure 1, and then flows to the air inlet end of the suction device 4, wherein the first flow path and the second flow path are parallel at least in the part extending along the axial direction of the dust cup assembly 3.

[0080] In the present embodiment, the dust cup assembly 3 is used to store the external dirt sucked into the dust cleaner device 100 during cleaning, and the suction device 4 is used to provide suction force; moreover, the air duct switching structure 1 has a first working state adapted to connect the suction device 4 and the dust collecting station 200, and a second working state adapted to connect the suction device 4 and the dust cup assembly 3, that is, the suction device 4 can be selectively connected with the device main body 2 and the dust collecting station 200; when the air duct switching structure 1 is in the first working state, the suction device 4 can be connected with the dust collecting station 200, and the suction device 4 provides suction power to form negative pressure in the dust collecting station 200, so that the dirt in the dust cup assembly 3 can be sucked out through the dust collecting station 200, realizing self-cleaning of the dust cleaner device 100; when the air duct switching structure 1 is in the second working state, the suction device 4 is connected with the dust cup assembly 3, and the suction device 4 forms negative pressure in the dust cup assembly 3, so that the external dirt can enter the dust cup assembly 3 from the dust suction port 24 of the dust cleaner device 100, realizing cleaning work of the dust cleaner device 100; moreover, the first flow path of the air flow during dust collection and the second flow path of the air flow during dirt discharge are parallel at least in the part extending along the axial direction of the dust cup assembly 3, and since the length of the dust cup assembly 3 is relatively long, most of the first flow path and the second flow path are parallel, which can make the channel structure more compact and occupy less space when the air flow collects dust and discharges dirt. The dust cleaner device 100 can have more functions without increasing the volume, and a separate power device does not need to be arranged in the dust collecting station 200 to perform self-cleaning of the dust cup assembly 3, and the structure of the dust collecting station 200 can be simpler, so the manufacturing cost is lower.

[0081] It should be noted that, since the dust cup assembly 3 generally has a cavity for storing dirt, the cavity is generally cylindrically arranged, and the axial direction of the dust cup assembly 3 is the axial direction of the cavity. Specifically, the dust cup assembly 3 includes a dust cup cavity 31 and a filtering structure, the dust cup cavity 31 is cylindrically arranged; the filtering structure is arranged in the dust cup cavity 31, and preferably the shape of the filtering structure is adapted to the shape of the dust cup cavity 31 and is coaxially arranged with the dust cup cavity 31, so that the suction airflow can uniformly enter the filtering structure after entering the dust cup cavity 31, ensuring better filtering effect; the filtering structure extends along the axial direction of the dust cup cavity 31 to form part of the first flow path, and the second flow path is located outside the dust cup cavity 31 and is at least partially arranged along the axial direction of the dust cup cavity 31, so that in the direction along the axial direction of the dust cup cavity 31, the first flow path and the second flow path can be substantially parallel, ensuring a more compact structure.

[0082] Further, as shown in FIGS. 3, 5 and 6, the filtering structure includes a first filtering structure 32, a second filtering structure 33 and a third filtering structure 34, the first filtering structure 32 is arranged on the inner side of the dust cup cavity 31 and is cylindrically arranged, and the first filtering structure 32 is arranged as a filter cylinder, and its shape is adapted to the shape of the dust cup cavity 31; the second filtering structure 33 is arranged on the inner circumferential side of the first filtering structure 32 and is in communication with the air outlet side of the first filtering structure 32, and preferably the second filtering structure 33 is arranged as a multi-cone filter; the third filtering structure 34 is arranged at one end of the dust cup cavity 31 in the axial direction and is in communication with the second filtering structure 33. The dust cup cavity 31 includes a cavity and a cavity cover, the cavity cover is arranged at one end of the cavity in the axial direction, and the third filtering structure 34 is arranged at the other end of the cavity in the axial direction. As shown in FIG. 7, the dashed arrows in FIG. 7 represent the airflow direction when the dust cleaner 100 is performing the dirt cleaning work, the suction airflow can enter the cavity through the side of the cavity, and after being filtered by the first filtering structure 32, it enters the second filtering structure 33, and after being filtered by the second filtering structure 33, the airflow is filtered by the third filtering structure 34 and then enters the air inlet end of the suction device 4, ensuring that the airflow is filtered clean before entering the suction device 4. The suction device 4 and the air duct switching structure 1 are both located on the side of the third filtering structure 34 away from the second filtering structure 33, and the dust cup cavity 31, the first filtering structure 32, the second filtering structure 33 and the third filtering structure 34 are coaxially arranged. This makes the space occupied by the suction device 4 and the air duct switching structure 1 in the axial direction of the dust cup cavity 31 smaller, so that the volume of the dust cup cavity 31 is large enough, and the volume of the entire dust cleaner 100 does not increase.

[0083] Preferably, the suction device 4 comprises an axial flow fan, which is arranged along the radial direction of the dust cup cavity 31 and perpendicular to the axial direction of the filtering structure. The axial direction of the axial flow fan is the extension direction of the rotation axis of the inner blade of the axial flow fan. Since the length of the axial flow fan in the axial direction is longer than that in the radial direction, the axial flow fan is arranged along the radial direction of the dust cup cavity 31, so that the dust collector 100 can be shorter in the axial direction of the dust cup cavity 31 and smaller in size.

[0084] Preferably, the suction device 4 and the air duct switching structure are arranged at the same end of the dust cup cavity 31 in the axial direction, so that the arrangement between the suction device 4 and the air duct switching structure 1 is more compact, and the air duct switching structure 1 is closer to the suction device 4, which can make the state switching control effect better. Specifically, as shown in FIGS. 3 and 4, the air duct switching structure 1 is arranged close to the air inlet end of the axial flow fan and has a reciprocating movement stroke in the axial direction of the dust cup cavity 31. The air duct switching structure 1 and the suction device 4 are arranged side by side at one end of the third filtering structure 34, so that the space occupied by the air duct switching structure 1 and the suction device 4 in the axial direction of the dust cup cavity 31 is smaller, and the air duct switching structure 1 has sufficient space for movement in the axial direction of the dust cup cavity 31, so that the space layout in the device body 2 is more reasonable and compact.

[0085] Moreover, the suction device 4 and the air duct switching structure 2 at least partially overlap in the radial direction of the dust cup cavity 31, so that the space occupied by the suction device 4 and the air duct switching structure 2 in the axial direction of the dust cup cavity 31 is less, and the length of the entire dust collector 100 in the axial direction can be shorter.

[0086] Specifically, for the arrangement of the first flow path and the second flow path, the first channel 21 and the second channel 22 are formed in the device body 2, the first channel 21 is connected to the dust cup assembly 3 and the suction device 4, and the second channel 22 is adapted to be connected to the suction device 4 and the dust collecting station 200; when the air duct switching structure 1 is in the first working state, the air duct switching structure 1 is arranged to block the first channel 21 and open the second channel 22, and when the air duct switching structure 1 is in the second working state, the air duct switching structure 1 is arranged to open the first channel 21 and block the second channel 22; the airflow passage between the suction port 24 and the third filtering structure 34 and the first channel 21 together form the first flow path, and the second channel 22 forms the second flow path. When the dust collector 100 is working, the airflow flows in the axial direction of the dust cup cavity 31 after being filtered by the filtering structure; when the dust collector 100 is working, the airflow can flow along the second channel 22, and most of the second channel 22 is arranged in the axial direction of the dust cup cavity 31, so that the first flow path occupies less additional space outside the dust cup cavity 31, and the second channel 22 and the dust cup cavity 31 can be arranged more compactly, so that the entire dust collector 100 can be smaller in size.

[0087] In order to make the air duct switching structure 1 occupy less space while better achieving switching of the two working states. Specifically, for the air duct switching structure 1, the air duct switching structure 1 includes the first blocking part 11 and the second blocking part 12, the first channel 21 has the first opening 211 in communication with the suction device 4, and the second channel 22 has the second opening 221 in communication with the suction device 4. When the air duct switching structure 1 is in the first working state, the first blocking part 11 blocks the first opening 211, and the second blocking part 12 opens the second opening 221, and when it is in the second working state, the first blocking part 11 opens the first opening 211, and the second blocking part 12 blocks the second opening 221. By controlling the conduction and blocking of the first opening 211 and the second opening 221, the switching of the two working modes is achieved, and the operation is simpler.

[0088] Since the axial direction of the axial flow fan is perpendicular to the axial direction of the dust cup cavity 31, the first opening 211 and the second opening 221 can be arranged close to the air inlet end of the axial flow fan, and the first opening 211 and the second opening 221 are arranged in opposite directions along the axial direction of the dust cup cavity 31. By making the first blocking part 11 and the second blocking part 12 move linearly along the axial direction of the dust cup cavity 31, the conduction and blocking of the first opening 211 and the second opening 221 are achieved.

[0089] Moreover, the second channel 22 includes a first conduction section extending along the axial direction of the dust cup assembly 3, and a second conduction section communicating the first conduction section and the second opening 221, the second conduction section extending along the lateral direction of the first conduction section. The length of the first conduction section is longer than the length of the second conduction section, so that the second channel 22 can be better arranged along the outside of the dust cup cavity 31, and the structure is more compact.

[0090] Among them, as shown in FIG. 2 and FIG. 6, the first air port 23 is a port forming the second channel, and the first air port 23 and the dust discharge port are located in the same plane. When the dust collector device 100 is placed on the dust collection station 200, after the dust discharge port is connected to the dust collection station 200, the first air port 23 can also be better connected to the dust collection station 200. Preferably, the dust discharge port is located at the front end of the device main body 2, and the first air port 23 is also located at the front end of the device main body 2. When the dust collector device 100 is placed on the dust collection station 200, the front end of the device main body 2 can be connected to the dust collection station 200. Moreover, the dust discharge port can be downwardly inserted into the dust collection station 200, and after the cover is opened, the dirt can be better dropped into the dust collection station 200.

[0091] Preferably, as shown in FIG. 2 and FIG. 11, the first air outlet 23 is provided with two, and the cleaner device further comprises a wind guide arranged in the device body, the wind guide comprises a wind guide plate 5 arranged in a groove shape, the wind guide plate is located outside the dust cup cavity 31 and forms a second channel with the dust cup cavity 31, and the first air outlet 23 is a port formed on the outer side surface of the device body 2. As shown in FIG. 6 and FIG. 11, the dashed arrows in FIG. 11 represent the flow direction of the air flow when the cleaner device 100 is performing the dirt discharging work, and the plurality of rib plates separate the second channel 22 into two branch channels, and the two branch channels are respectively communicated with the two first air outlets 23, and the two first air outlets 23 are communicated with the two docking ports on the dust collecting station 200, so that the suction device 4 is communicated with the dust collecting station 200, the air flow is larger, and the dirt discharging efficiency of the dust collecting station 200 to the dust cup assembly 3 can be effectively improved.

[0092] Among them, the device body 2 is provided with a dust suction channel suitable for communicating the dust cup cavity 31 and the outside, and the dust suction channel can guide the external dirt into the dust cup cavity 31, and the dust suction port 24 of the dust suction channel is arranged on the outer surface of the device body 2 and is located in the same plane as the first air outlet 23. The dust suction port 24 is arranged at the front end of the device body 2, so that the dust suction port 24 can be closer to the surface to be cleaned, and the handle of the device body 2 is located at the rear end, so that the operation is more comfortable when the cleaner device 100 is operated to perform the cleaning work.

[0093] Among them, the first channel 21 and the second channel 22 both have two working states of communication and blocking, so that the first channel 21 and the second channel 22 can have four working conditions when working. For example, when the first channel 21 is in the communication state, the second channel 22 can be in the communication state or in the blocking state; when the first channel 21 is in the blocking state, the second channel 22 can be in the communication state or the second channel 22 is in the blocking state.

[0094] It can be understood that if both channels are in the open state, the airflow formed by the suction device 4 will be divided, and the suction force entering each channel will be reduced; if both channels are in the closed state, there is no continuous airflow into the air inlet side of the suction device 4, forming a vacuum, and the pressure on the air inlet side of the suction device 4 is too small, which can cause the air inlet side to be squeezed and deformed, or the suction device 4 can overheat, causing damage. Therefore, preferably, the air duct switching structure 1 is movable to have a first working state of closing the first channel 21 and opening the second channel 22, and a second working state of opening the first channel 21 and closing the second channel 22. So that when the suction device 4 is in communication with the dust cup assembly 3, the suction device 4 and the dust collection station 200 are in a closed state, and the vacuum cleaner 100 can better perform the cleaning work; when the suction device 4 is in communication with the dust collection station 200, the suction device 4 and the dust cup assembly 3 are in a closed state, and the self-cleaning effect of the dust collection station 200 on the dust cup assembly 3 is better.

[0095] Further preferably, as shown in FIGS. 3 and 4, the first channel 21 has a first opening 211 in communication with the suction device 4, and the second channel 22 has a second opening 221 in communication with the suction device 4; in the first working state, the first blocking part 11 is arranged to close the first opening 211, and the second blocking part 12 is arranged to open the second opening 221; in the second working state, the first blocking part 11 is arranged to open the first opening 211, and the second blocking part 12 is arranged to close the second opening 221, so that only one of the two channels can be in the open state, so that the airflow generated by the suction device 4 can only flow along one channel, and the phenomenon of both channels being connected or both channels being closed can be avoided, and the vacuum cleaner 100 can be better protected.

[0096] Of course, in another embodiment, the first blocking part 11 and the second blocking part 12 can be provided only one, and the opening and closing of the two openings can be achieved by the movement of one blocking part, and the switching between the first working state and the second working state can also be achieved. However, by blocking and opening the first opening 211 and the second opening 221 by the first blocking part 11 and the second blocking part 12 respectively, the movement stroke of the first blocking part 11 and the second blocking part 12 can be shorter, and the internal space occupied can be smaller, so the structure will be more compact.

[0097] The first shielding part 11 and the second shielding part 12 can be independently arranged, that is, the first shielding part 11 and the second shielding part 12 can be arranged in different ways. For example, after or before the first shielding part 11 blocks the first opening 211, the second shielding part 12 moves to open the second opening 221; or after or before the first shielding part 11 opens the first opening 211, the second shielding part 12 moves to block the second opening 221. The first shielding part 11 and the second shielding part 12 do not affect each other, and are more flexible.

[0098] Preferably, the first shielding part 11 and the second shielding part 12 are arranged in linkage, that is, the first shielding part 11 and the second shielding part 12 are synchronous. In the first working state, the first shielding part 11 blocks the first opening 211, and at the same time, the second shielding part 12 guides the second opening 221; in the second working state, the second shielding part 12 blocks the second opening 221, and at the same time, the first shielding part 11 guides the first opening 211. Specifically, the air duct switching structure 1 further comprises a first transmission member 13 movably arranged in the equipment main body 2, the first transmission member 13 is connected with the first shielding part 11 and the second shielding part 12, the first transmission member 13 is moved under the action of external force, and drives the first shielding part 11 and the second shielding part 12 to move together. The first transmission member 13 can be moved under the action of manual, or can be moved under the action of a driving device, or the first transmission member 13 can be moved under the action of the dust collecting station 200, so as to switch the working state of the first shielding part 11 and the second shielding part 12, and better ensure the working effect of the dust collector equipment 100.

[0099] Next, when the first shielding part 11 and the second shielding part 12 are arranged in linkage, the movement of the first transmission member 13 is controlled, so as to drive the first shielding part 11 and the second shielding part 12 to move together.

[0100] Specifically, the first transmission member 13 comprises a first transmission rod 131, the first shielding part 11 and the second shielding part 12 are arranged in a spaced manner along the length direction of the first transmission rod 131, and the first transmission rod 131 is movably arranged in the first opening 211 and the second opening 221. The first opening 211 and the second opening 221 are arranged in opposite directions along the second direction, and the first shielding part 11 and the second shielding part 12 can move together by reciprocating the first transmission rod 131 along the second direction, so as to be in the first working state and the second working state, respectively.

[0101] Further, the first shielding part 11 comprises a first shielding plate which is arranged radially protruding from the first transmission rod 131, and the second shielding part 12 comprises a second shielding plate which is arranged radially protruding from the first transmission rod 131. The first shielding plate and the second shielding plate are respectively located on the side away from the first opening 211 and the second opening 221. When the first shielding plate is close to the first opening 211, the second shielding plate moves away from the second opening 221. When the first shielding plate moves away from the first opening 211, the second shielding plate moves towards the second opening 221. The first shielding plate and the second shielding plate are both substantially flat, and the size of the first shielding plate is adapted to the size of the first opening 211, and the size of the second shielding plate is adapted to the size of the second opening 221. Preferably, the first opening 211 and the second opening 221 are both circular and have the same diameter.

[0102] At least one of the first shielding plate and the second shielding plate is arranged in detachable connection with the first transmission rod 131, so as to facilitate the installation and disassembly of the air duct switching structure 1. Preferably, the first shielding plate is arranged integrally with the first transmission rod 131, and the second shielding plate is arranged detachably on the first transmission rod 131, so that the assembly is less and easy to disassemble. During assembly, the first transmission rod 131 can be arranged in the first opening 211 towards the second opening 221, and then the second shielding plate is sleeved on the first transmission rod 131, so as to be fixed.

[0103] Furthermore, as shown in FIG. 4, the air duct switching structure 1 further comprises a first sealing member 14 which is sleeved on the outer circumferential side of the first shielding plate. When in the first working state, the first shielding plate is located at the first opening 211, and at least part of the first sealing member 14 is located at the gap between the first opening 211 and the first shielding plate. A first air guide surface 141 is formed on the first sealing member 14, which is located upstream of the first opening 211 in the direction of airflow. The outer diameter of the first air guide surface gradually increases in the axial direction of the first opening 211 and in the direction of airflow. The airflow from the dust cup assembly 3 can flow better in the direction of the first opening 211 under the guidance of the first air guide surface 141, avoiding direct convergence and impact on the circumferential side of the first opening 211, thereby reducing energy loss. Specifically, the first sealing member 14 is arranged in a substantially conical shape, and the first air guide surface 141 is formed on the outer surface of the conical shape. An elastic sealing arm is arranged at the end of the large end surface of the conical structure. When the first shielding plate is closed at the first opening 211, the elastic sealing arm and the conical structure are respectively located on both sides of the first opening 211. The connection between the elastic sealing arm and the conical structure is sealed with the circumferential side of the first opening 211, thereby ensuring better sealing effect.

[0104] As shown in FIG. 4, the air duct switching structure 1 further comprises a second sealing member 15 sleeved on the outer circumferential side of the second shielding plate. When the second shielding plate is located at the second opening 221 and at least part of the second sealing member 15 is located at the gap between the second opening 221 and the second shielding plate, the second sealing member 15 is provided with an elastic sealing arm. The second sealing member 15 is arranged on the first side of the second opening 221. When the second shielding plate blocks the second opening 221, the elastic sealing arm is elastically deformed to extend from the first side of the second opening 221 to the second side of the second opening 221 and seal the second opening 221. The second opening 221 can be better sealed when the second shielding plate blocks the second opening 221.

[0105] In addition, the first guide column 17 is arranged in the device body 2 and extends along the direction from the first opening 211 to the second opening 221. The first transmission rod 131 is hollow and movably sleeved on the outer side of the first guide column 17. During the movement of the first transmission rod 131, the first guide column 17 guides the movement of the first transmission rod 131, so that the movement of the first transmission rod 131 is more stable and less likely to shake. Therefore, the first shielding plate and the second shielding plate are more accurately aligned when they block the openings, and the blocking effect is better.

[0106] In an embodiment, the air duct switching structure 1 further comprises a second transmission member 16 connected with the first transmission member 13. The second transmission member 16 is moved by external force to drive the first transmission member 13 to move, so that the first shielding plate and the second shielding plate are switched between the first working state and the second working state. The second transmission member 16 drives the first transmission member 13 to move, and the dust collection station 200 can better act on the air duct switching structure 1 through the second transmission member 16. The dust collector device 100 and the dust collection station 200 are connected to switch the working state of the air duct switching structure 1, so that the operation is more convenient.

[0107] Further, as shown in FIG. 4 to FIG. 6, the second transmission member 16 comprises a second transmission rod 161, and a first connecting head 162 and a second connecting head 163 respectively arranged at two ends of the second transmission rod 161, the first connecting head 162 is connected with the first transmission member 13, and the first connecting head 162 and the second connecting head 163 are detachably connected with the second transmission rod 161, so as to facilitate assembly. When the dust collector device 100 is adapted to be connected with the dust collecting station 200 or after being connected with the dust collecting station 200, the second connecting head 163 is adapted to be moved under the action of the trigger part 201 on the dust collecting station 200, and drives the second transmission rod 161, the first connecting head 162 and the first transmission member 13 to move together, so that the first shielding part 11 and the second shielding part 12 can be switched between the first working state and the second working state. Among them, the second connecting head 163 is arranged close to the outer side of the device main body 2, so that when the dust collector device 100 is connected with the dust collecting station 200 or after being connected with the dust collecting station 200, the trigger part 201 on the dust collecting station 200 can act on the second connecting head 163, so as to drive the second connecting head 163 to move, thereby driving the second transmission member 16 to move, so as to drive the first transmission rod 131 to move in the second direction.

[0108] Preferably, the second transmission rod 161 is arranged to extend in the axial direction of the dust cup cavity 31, the first transmission member 13 is located at one end of the dust cup assembly 3 in the axial direction, the second connecting head 163 is located at the other end of the dust cup assembly 3 in the axial direction, the first transmission rod 131 and the second transmission rod 161 are arranged in parallel and both extend in the axial direction of the dust cup cavity 31, and similarly, the space occupied in the radial direction of the dust cup cavity 31 is smaller, so as to ensure that the structure is more compact. At least part of the second connecting head 163 can be exposed from the plane where the first air port 23 is located, so that when the dust collector device 100 is connected with the dust collecting station 200, the trigger part 201 on the dust collecting station 200 can better act on the second connecting head 163, so as to drive the entire second transmission member 16 to move better.

[0109] Moreover, a guide groove 25 extending in the direction from the first opening 211 to the second opening 221 is formed in the device main body 2, and the second transmission rod 161 is movably arranged in the guide groove 25, so that the second transmission rod 161 is more stable when moving through the guiding action of the guide groove 25. A plurality of partitions are arranged in the guide groove 25, and the second transmission rod 161 movably passes through the plurality of partitions, so as to ensure better guiding property. Moreover, a limiting protrusion can be protrudingly arranged on the second transmission rod 161, and the limiting protrusion can abut against one or more partitions, so as to limit the movement stroke of the second transmission rod 161, so as to better control the movement position of the first shielding plate and the second shielding plate, and avoid excessive movement and resulting in non-resetting.

[0110] Further, as shown in FIG. 4, the air duct switching structure 1 further comprises an elastic extension piece 18, which can be provided as an elastic spring. The two ends of the elastic extension piece 18 abut between the second transmission rod 161 and the second opening 221. When the dust cleaner device 100 is placed on the dust collecting station 200, the second transmission rod 16 is moved under the abutting action of the trigger part 201 of the dust collecting station 200. At this time, the first shutter plate is arranged to block the first opening 211, the second shutter plate is arranged to open the second opening 221, and the elastic extension piece 18 is in an elastic energy storage state (such as an extension or compression state). The dust cleaner device 100 is in a pollution discharge state. When the dust cleaner device 100 is removed from the dust collecting station 200, the second transmission rod 16 is no longer acted on by the trigger part 201. Under the action of the elastic restoring force of the elastic extension piece 18, the first transmission rod 131 is reset, so that the first shutter plate opens the first opening 211, and the second shutter plate blocks the second opening 221. The dust cleaner device 100 enters a dust cleaning state. Therefore, when the dust cleaner device 100 is placed on the dust collecting station 200, the air duct switching structure 1 can automatically enter a first working state, so that the suction device 4 can be in communication with the dust collecting station 200, to facilitate the dust cup assembly 3 to discharge pollution. After the dust cleaner device 100 is removed from the dust collecting station 200, the air duct switching structure 1 can automatically enter a second working state, so that the suction device 4 can be in communication with the dust cup assembly 3, and the dust cleaner device 100 automatically enters a dust cleaning state. The use of the dust cleaner device 100 is more convenient, and the user does not need to perform switching operation of the air duct switching structure 1, which is more convenient to use.

[0111] For the device main body 2, the outer shape of the device main body 2 can be various to meet the use requirements of different users. In an embodiment, the device main body 2 is arranged in a substantially long strip-shaped column, the front end of the device main body 2 is provided with a dust suction port 24, the rear end of the device main body 2 is provided with a handle, and the dust cup assembly 3 and the suction device 4 are arranged along the front-rear direction of the device main body 2. Here, front and rear refer to the end close to the surface to be cleaned as front and the end away from the surface to be cleaned as rear when the dust cleaner device 100 is normally used.

[0112] The present disclosure also provides a dust cleaner system 1000, which is shown in FIGS. 9 to 11 and comprises a dust collecting station 200 and the above-mentioned dust cleaner device 100. The dust collecting station 200 can be in communication with the dust cleaner device 100. When or after the dust collecting station 200 and the dust cleaner device 100 are in communication, the suction device 4 of the dust cleaner device 100 can form a negative pressure in the dust collecting station 200, to suck the dirt at the dust cleaner device 100 into the dust collecting station 200, to realize self-cleaning of the dust cleaner device 100.

[0113] Preferably, the working mode of the cleaner device 100 can be switched by the air duct switching structure 1 on the cleaner device 100, so that the suction device 4 of the cleaner device 100 can be communicated with the dust cup assembly 3 to perform cleaning work, and the suction device 4 of the cleaner device 100 can be communicated with the dust collecting station 200, so that a negative pressure can be formed in the dust collecting station 200, and then the dust collecting station 200 can be formed by the suction device 4, and then the dirt in the dust cup assembly 3 can be sucked into the dust collecting station 200, so as to realize self-cleaning of the cleaner device 100.

[0114] In combination with FIG. 10, when the cleaner device 100 is docked with the dust collecting station 200, the trigger part 201 on the dust collecting station 200 can act on the second connecting head 163 on the second transmission rod 161, so as to drive the second transmission rod 161 to move backward, drive the second shielding plate to open the second opening 221, and drive the first shielding plate to block the first opening 211, so that the suction device 4 can be communicated with the dust collecting station 200 through the second passage 22. The acting part can be provided as a top abutting protrusion, which can be at least partially extended into the guide groove 25 to abut against the second connecting head 163. When the cleaner device 100 is placed on the dust collecting station 200, the air duct switching structure 1 can automatically switch the working state, so that the suction device 4 can be automatically communicated with the dust collecting station 200, without the need for manual adjustment by the user, which is more convenient to operate. In addition, the dust collecting station 200 does not need to be provided with a power device for discharging the dust cup assembly 3, and the structure of the dust collecting station 200 is also simpler, and the cost is also lower.

[0115] The above only describes the preferred embodiments of the present disclosure, and does not limit the patent scope of the present disclosure, and any equivalent structure or direct or indirect application in other related technical fields by using the content of the present disclosure and the drawings is also included in the patent protection scope of the present disclosure.
