[0082] The disclosure provides a dust collector device 100, specifically, please refer to FIG. 1 to FIG. 3, in the embodiment, the dust collector device 100 includes device main body 2, dust cup assembly 3, suction device 4 and air duct switching structure 1, wherein, the first channel 21 and the second channel 22 are formed on the device main body 2;The dust cup assembly 3 is arranged on the device main body 2;The suction device 4 is arranged on the device main body 2, the first channel 21 is communicated with the suction device 4 and the dust cup assembly 3, the second channel 22 is suitable for communicating the suction device 4 and the dust collection station 200;The air duct switching structure 1 includes the first shielding part 11 and the second shielding part 12 which are movably arranged, the first shielding part 11 is used for blocking and conducting the first channel 21, the second shielding part 12 is used for blocking and conducting the second channel 22, the first shielding part 11 and the second shielding part 12 are moved so that one of the first channel 21 and the second channel 22 is in the conducting state, and the other is in the blocking state.

[0083] In the embodiment, the dust cup assembly 3 can be used to store the external dirt sucked by the cleaner device 100 during the cleaning process, and the suction device 4 is used to provide suction force; and the working states of the first channel 21 and the second channel 22 in the device main body 2 can be switched by the air duct switching structure 1, so that one of the first channel 21 and the second channel 22 is in a communication state and the other is in a blocking state, i.e. the suction device 4 can be selectively communicated with the device main body 2 and the dust collecting station 200. When the air duct switching structure 1 communicates the first channel 21, the suction device 4 is communicated with the dust cup assembly 3, and the suction device 4 forms a negative pressure in the dust cup assembly 3, so that the external dirt can enter the dust cup assembly 3 from the suction port 24 of the cleaner device 100, thereby realizing the cleaning work of the cleaner device 100; and the air duct switching structure 1 includes the first shielding part 11 and the second shielding part 12, which are used to block and communicate the first channel 21 and the second channel 22, respectively. The active stroke of the first shielding part 11 and the second shielding part 12 can be relatively smaller, so the space occupied is smaller and the structure is more compact; when the air duct switching structure 1 communicates the second channel 22, the suction device 4 can be communicated with the dust collecting station 200, and the suction device 4 provides suction power to form a 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, thereby realizing the self-cleaning of the cleaner device 100. The cleaner device 100 has more diversified functions without increasing the suction device 4, and the dust collecting station 200 does not need to be provided with a separate power device for self-cleaning of the dust cup assembly 3, so the structure of the dust collecting station 200 can be simpler and the manufacturing cost is lower.

[0084] The first channel 21 and the second channel 22 each have two working states of communication and blocking, so 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 a communication state, the second channel 22 can be in a communication state or in a blocking state; when the first channel 21 is in a blocking state, the second channel 22 can be in a communication state or the second channel 22 is in a blocking state.

[0085] 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; and 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 cleaner 100 can better perform the cleaning work; and 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.

[0086] Preferably, the first shielding part 11 moves linearly back and forth; the second shielding part 12 also moves linearly back and forth. So that the moving stroke of the first shielding part 11 and the second shielding part 12 is relatively small, and therefore the internal space required is smaller, so that the size of the cleaner 100 can be smaller.

[0087] Preferably, the first shielding part 11 is located at the end of the first channel in the airflow direction, and when the suction airflow is formed in the first channel, the first shielding part 11 is arranged at the air outlet end of the first channel. By arranging the first shielding part 11 closer to the suction device 4, the control of the closing and opening of the first channel can be more sensitive. Similarly, the second shielding part 12 is located at the end of the second channel in the airflow direction, and when the suction airflow is formed in the second channel, the second shielding part 12 is arranged at the air outlet end of the second channel. By arranging the second shielding part 12 closer to the suction device 4, the control of the closing and opening of the second channel can be more sensitive.

[0088] Preferably, the first shielding part 11 and the second shielding part 12 are arranged opposite to each other and located on both sides of the air inlet end of the suction device 4 in the axial direction, so as to be symmetrically arranged on both sides of the suction device 4 and closer to the air inlet end of the suction device 4. So that the airflow formed in each air duct is more efficient and consumes less energy, thereby improving the dust collection efficiency of the cleaner 100 and the dust discharge efficiency of the dust cup assembly 3.

[0089] Further preferably, as shown in FIG. 3 and FIG. 4, the first channel 21 has a first connecting port 211 in communication with the suction device 4, and the second channel 22 has a second connecting port 221 in communication with the suction device 4; when in the first working state, the first blocking part 11 blocks the first connecting port 211, and the second blocking part 12 opens the second connecting port 221; when in the second working state, the first blocking part 11 opens the first connecting port 211, and the second blocking part 12 blocks the second connecting port 221, so that only one of the two channels is in a conductive state, and the airflow generated by the suction device 4 can only flow along one channel, which can avoid the phenomenon that both channels are connected or both channels are blocked, and can better protect the cleaner 100.

[0090] Of course, in another embodiment, the first blocking part 11 and the second blocking part 12 can be provided with only one, and the opening and blocking of the two connecting ports 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 connecting port 211 and the second connecting port 221 respectively by the first blocking part 11 and the second blocking part 12, the movement stroke of the first blocking part 11 and the second blocking part 12 can be shorter than that of one blocking part, and the internal space occupied is smaller, so the structure is more compact.

[0091] Among them, the first blocking part 11 and the second blocking part 12 can be independently provided, that is, the movement mode of the first blocking part 11 and the movement mode of the second blocking part 12 can be different. For example, after or before the first blocking part 11 blocks the first connecting port 211, the second blocking part 12 moves to open the second connecting port 221; or after or before the first blocking part 11 opens the first connecting port 211, the second blocking part 12 moves to block the second connecting port 221. The movement of the first blocking part 11 and the second blocking part 12 does not affect each other, and is more flexible.

[0092] Preferably, the first blocking part 11 and the second blocking part 12 are in linkage, i.e. the first blocking part 11 and the second blocking part 12 are in synchronous movement. In the first working state, the first blocking part 11 blocks the first connecting port 211 while the second blocking part 12 leads the second connecting port 221; in the second working state, the second blocking part 12 blocks the second connecting port 221 while the first blocking part 11 leads the first connecting port 211. Specifically, the air duct switching structure 1 further comprises a first transmission member 13 movably arranged in the device main body 2, the first transmission member 13 is connected with the first blocking part 11 and the second blocking part 12, the first transmission member 13 is moved by external force to drive the first blocking part 11 and the second blocking part 12 to move together. Wherein, the first transmission member 13 can be moved by manual action, or can be moved by the driving device, or the first transmission member 13 can be moved by the dust collecting station 200, so as to switch the working state of the first blocking part 11 and the second blocking part 12, and better ensure the working effect of the dust collector 100.

[0093] Next, the linkage of the first blocking part 11 and the second blocking part 12 will be described in detail. By controlling the movement of the first transmission member 13, the first blocking part 11 and the second blocking part 12 can be driven to move together.

[0094] In an embodiment, the first transmission member 13 can be rotatably arranged in the device main body 2, the first transmission member 13 rotates to drive the first blocking part 11 and the second blocking part 12 to rotate together to switch between the first working state and the second working state, and realize the connection of the suction device 4 with the dust collecting station 200 and the dust cup assembly 3.

[0095] In another embodiment, the first transmission member 13 has a linear reciprocating movement, the first transmission member 13 moves to drive the first blocking part 11 and the second blocking part 12 to move together to switch between the first working state and the second working state.

[0096] In the embodiment, the air inlet end of the suction device 4 is arranged towards a lateral side of the device body 1, the first connection port 211 and the second connection port 221 are arranged on two sides of the air inlet end of the suction device 4 in the axial direction, and at least part of the orthographic projection of the first transmission member 13 in the axial direction of the air inlet end of the suction device 4 is located in the lateral region of the suction device 4. When the device body 1 is arranged in a substantially cylindrical shape, the lateral direction herein can refer to the radial direction of the device body 1, the air inlet end of the suction device 4 is arranged towards a radial side of the device body 1, and the first connection port 211 and the second connection port 221 are arranged on two sides of the air inlet end of the suction device 4, so that the airflow effect in each channel is more consistent, and the first transmission member 13 and the suction device 4 at least partially overlap in the axial direction, so that the axial space occupied can be smaller, and the length of the entire cleaner device 100 in the axial direction can be shorter, and the volume is smaller.

[0097] In the embodiment, the first transmission member 13 is arranged to move linearly, and the first shielding part 11 and the second shielding part 12 are arranged as two separate components, the first shielding part 11 is used to shield and open the first connection port 211, and the second shielding part 12 can be used to shield and open the second connection port 221. Specifically, the first transmission member 13 includes 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 sleeved in the first connection port 211 and the second connection port 221. In the embodiment, the first connection port 211 and the second connection port 221 are arranged in opposite directions along the second direction, and the first transmission rod 131 is arranged to move linearly in the second direction, so that the first shielding part 11 and the second shielding part 12 can be moved together to be in the first working state and the second working state, respectively.

[0098] Further, the first shielding part 11 includes a first shielding plate, which is arranged to protrude from the first transmission rod 131 in the radial direction of the first transmission rod 131; the second shielding part 12 includes a second shielding plate, which is arranged to protrude from the first transmission rod 131 in the radial direction of the first transmission rod 131, and the first shielding plate and the second shielding plate are located on the sides away from the first connection port 211 and the second connection port 221, respectively. When the first shielding plate moves towards the first connection port 211, the second shielding plate moves away from the second connection port 221, and when the first shielding plate moves away from the first connection port 211, the second shielding plate moves towards the second connection port 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 connection port 211, and the size of the second shielding plate is adapted to the size of the second connection port 221. Preferably, the first connection port 211 and the second connection port 221 are both circular and have the same diameter.

[0099] At least one of the first baffle plate and the second baffle plate is detachably connected with the first transmission rod 131, so as to facilitate the installation and disassembly of the air duct switching structure 1. Preferably, the first baffle plate is integrally arranged with the first transmission rod 131, and the second baffle plate is detachably arranged on the first transmission rod 131, so that the assembly is less and easy to disassemble. When assembling, the first transmission rod 131 can be arranged in the first connecting port 211 towards the direction of the second connecting port 221, and then the second baffle plate is sleeved on the first transmission rod 131, so as to be fixed.

[0100] Moreover, 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 baffle plate, and a first air guide surface 141 is formed on the first sealing member 14. In the direction of airflow, the first air guide surface is located upstream of the first connecting port 211. In the axial direction of the first connecting port 211 and in the direction of airflow, the outer diameter of the first air guide surface is gradually increased. The airflow from the dust cup assembly 3 can flow better in the direction of the first connecting port 211 under the guidance of the first air guide surface 141, avoiding direct convergence and impact on the circumferential side of the first connecting port 211, thereby causing 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. The elastic sealing arm is arranged at the end of the large end surface of the conical structure. When the first baffle plate is blocked at the first connecting port 211, the elastic sealing arm and the conical structure can be located on both sides of the first connecting port 211, respectively. The connection between the elastic sealing arm and the conical structure is sealed with the circumferential side of the first connecting port 211, thereby ensuring better sealing effect.

[0101] As shown in FIG. 4, the air duct switching structure 1 further comprises a second sealing member 15, which is sleeved on the outer circumferential side of the second baffle plate. The second sealing member 15 is also provided with an elastic sealing arm. The second sealing member 15 is arranged on the first side of the second connecting port 221. In the second working state, the elastic sealing arm is elastically deformed to extend from the first side of the second connecting port 221 to the second side of the second connecting port 221 and form a seal with the second connecting port 221. When the second baffle plate blocks the second connecting port 221, the second connecting port 221 can be better sealed.

[0102] In addition, the first guide column 17 is arranged in the device body 2 and extends along the direction from the first connecting port 211 to the second connecting port 221, and the first transmission rod 131 is hollow and movably sleeved on the outside 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, and thus the first and second shielding plates are more accurately positioned and have a better plugging effect when plugging.

[0103] In an embodiment, the air duct switching structure 1 further comprises a second transmission member 16 connected with the first transmission member 13, and the second transmission member 16 is moved by external force to drive the first transmission member 13 to move, so that the first shielding part 11 and the second shielding part 12 are switched between the first working state and the second working state. The second transmission member 16 acts on the first transmission member 13 to drive the first and second shielding plates to move, and the second transmission member 16 makes the dust collection station 200 better act on the air duct switching structure 1, so that 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, and the operation is more convenient.

[0104] Further, as shown in FIGS. 4-6, the second transmission member 16 comprises a second transmission rod 161 and first and second connecting heads 162 and 163 arranged at two ends of the second transmission rod 161, respectively. The first connecting head 162 is connected with the first transmission member 13, and the first and second connecting heads 162 and 163 are detachably connected with the second transmission rod 161 for assembly. When the dust collector device 100 is adapted to be connected with the dust collection station 200 or after being connected, the second connecting head 163 is adapted to be moved under the action of the trigger part 201 on the dust collection station 200 and drive the second transmission rod 161, the first connecting head 162 and the first transmission member 13 to move together, so that the first and second shielding parts 11 and 12 can be switched between the first working state and the second working state. The second connecting head 163 is arranged close to the outside of the device body 2, so that when the dust collector device 100 is connected with the dust collection station 200 or after being connected, the trigger part 201 on the dust collection station 200 acts on the second connecting head 163 to drive the second connecting head 163 to move, thereby driving the second transmission member 16 to move to drive the first transmission rod 131 to move in the second direction.

[0105] Moreover, a guide groove 25 is formed in the device body 2 and extends along a direction from the first connecting port 211 to the second connecting port 221. The second transmission rod 161 is movably arranged in the guide groove 25, and the guide groove 25 guides the movement of the second transmission rod 161. A plurality of partitions are arranged in the guide groove 25, and the second transmission rod 161 movably passes through the partitions. The second transmission rod 161 can further protrude a limiting protrusion, which abuts against one or more of the partitions to limit the movement of the second transmission rod 161, so as to better control the movement positions of the first and second shielding plates and avoid excessive movement and non-resetting.

[0106] Further, as shown in FIG. 4, the air duct switching structure 1 further includes an elastic expansion member 18, which can be a telescopic spring. The two ends of the elastic expansion member 18 abut between the second transmission rod 161 and the second connecting port 221. When the dust collector device 100 is placed on the dust collecting station 200, the trigger portion 201 of the dust collecting station 200 abuts against the second transmission member 16, which moves. At this time, the first shielding plate blocks the first connecting port 211, and the second shielding plate opens the second connecting port 221. The elastic expansion member 18 is in an elastic energy storage state (e.g., an expansion or compression state), and the dust collector device 100 is in a pollution discharge state. When the dust collector device 100 is removed from the dust collecting station 200, the second transmission member 16 is no longer acted on by the trigger portion 201, and the elastic restoring force of the elastic expansion member 18 causes the first transmission rod 131 to reset, so that the first shielding plate opens the first connecting port 211, and the second shielding plate blocks the second connecting port 221. The dust collector device 100 enters a dust cleaning state. Therefore, when the dust collector device 100 is placed on the dust collecting station 200, the air duct switching structure 1 automatically enters a first working state, so that the suction device 4 is in communication with the dust collecting station 200, and the dust cup assembly 3 discharges dirt. When the dust collector device 100 is removed from the dust collecting station 200, the air duct switching structure 1 automatically enters a second working state, so that the suction device 4 is in communication with the dust cup assembly 3, and the dust collector device 100 automatically enters a dust cleaning state. The use of the dust collector device 100 is more convenient, and the user does not need to perform switching operations on the air duct switching structure 1, which is more convenient to use.

In an embodiment, the device body 2 is substantially in a long strip-shaped columnar shape, the device body 2 is provided with a dust suction port 24 at a front end, and a handle is provided at a rear end. The dust cup assembly 3 and the suction device 4 are arranged in sequence along the front-rear direction of the device body 2. Here, front and rear refer to, when the dust collector device 100 is normally used, the end close to the surface to be cleaned is the front, and the end away from the surface to be cleaned is the rear.

[0108] The axial direction of the air inlet end of the suction device 4 is the first direction, the first connection port 211 and the second connection port 221 are located close to the air inlet end of the suction device 4, and the first connection port 211 and the second connection port 221 are oppositely arranged along the second direction, wherein the first direction and the second direction are perpendicular. The first connection port 211 and the second connection port 221 are located close to the air inlet end of the suction device 4, so that the air resistance is smaller and the air inlet efficiency is higher. Moreover, the first connection port 211 and the second connection port 221 are opposite and symmetrically arranged at the air inlet end of the suction device 4, so that the relative positions between the first connection port 211, the second connection port 221 and the air inlet end of the suction device 4 are consistent, and the airflow effect in the first channel 21 and the second channel 22 is consistent. Preferably, the equipment body 2 is substantially cylindrical, the second direction is the axial direction of the equipment body 2, and the first direction is the radial direction of the equipment body 2.

So that the axial flow fan can occupy less axial space, the axial length of the entire vacuum cleaner device 100 can be shorter, and the volume can be smaller.

When the vacuum cleaner is in a vacuuming state, the airflow can enter the dust cup cavity 31 through the dust suction port 24 on the equipment body 2, flow through the filter structure, and then enter the first channel 21, and then enter the air inlet end of the suction device 4 through the first channel 21. The axial direction of the filter structure is the direction of the filter center line of the filter structure, and by arranging the second channel 22 parallel to the filter structure, the structure is more compact.
