Description

Technical Field

[0002] Vacuum cleaners, such as vacuum cleaners, floor scrubbers, and sweepers, can be connected to a dust collection station after cleaning. The motor on the dust collection station provides dust removal power, which sucks and discharges the dirt in the dust collection chamber of the vacuum cleaner. The vacuum cleaner's dust removal process does not require the user to manually empty the dust, and in this way, the user does not need to empty the dust after each cleaning. The user can empty the dust once a month or even longer. However, the existing dust removal method of this type of vacuum cleaner requires the dust collection station to provide dust removal power, and the dust collection station needs to be equipped with a motor, as well as dust exhaust channels or components connected to the motor, which makes the internal structure of the dust collection station complex and increases the production cost of the dust collection station.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0075] The present invention provides a vacuum cleaner device 100. Specifically, please refer to Figures 1 to 3 The vacuum cleaner device 100 includes an equipment body 2, a dust cup assembly 3, a suction device 4 and an air duct switching structure 1 arranged on the equipment body 2, and a first air inlet 23 suitable for connecting and communicating with the dust collecting station 200, and a dust suction port 24 are provided on the equipment body 2; the air duct switching structure 1 is movably arranged on the equipment body 2, and the air duct switching structure 1 has a first working state suitable for connecting the suction device 4 and the dust collecting station 200, and a second working state having a connection between the suction device 4 and the dust cup assembly 3; wherein, 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 after passing through the air duct switching structure 1, flows toward the air inlet end of the suction device 4; 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 flows toward 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 axially along the dust cup assembly 3.

[0076] In this embodiment, the dust cup assembly 3 can be used to store external dirt sucked in by the vacuum cleaner device 100 during the cleaning process, and the suction device 4 is used to provide suction force; moreover, the air duct switching structure 1 has a first working state suitable for connecting the suction device 4 and the dust collecting station 200, and a second working state having the suction device 4 connected to the dust cup assembly 3, that is, the suction device 4 can be selectively connected to the device 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 to the dust collecting station 200, and the suction power is provided by the suction device 4, so that a negative pressure is formed in the dust collecting station 200, and then the dirt in the dust cup assembly 3 can be sucked out through the dust collecting station 200, thereby achieving The present vacuum cleaner device 100 performs self-cleaning; when the air duct switching structure 1 is in the second working state, the suction device 4 is connected to the dust cup assembly 3, and the suction device 4 forms a negative pressure in the dust cup assembly 3, so that external dirt can enter the dust cup assembly 3 from the dust suction port 24 of the vacuum cleaner device 100, thereby achieving the cleaning work of the vacuum cleaner device 100; moreover, the first flow path when the airflow is performing dust collection and the second flow path when the airflow is performing waste discharge are parallel at least in the portion extending along the axial direction of the dust cup assembly 3. 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 of the airflow during dust collection and waste discharge more compact and occupy less space. The vacuum cleaner device 100 can have more diverse functions without increasing the volume, and there is no need to set up a separate power device in the dust collection station 200 to perform self-cleaning of the dust cup assembly 3. The structure of the dust collection station 200 can be simpler, and therefore the manufacturing cost is also lower.

[0077] It should be noted that since the dust cup assembly 3 generally has a cavity for storing dirt, the cavity is roughly cylindrical, 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 filter structure. The dust cup cavity 31 is cylindrical; the filter structure is arranged in the dust cup cavity 31. Preferably, the shape of the filter structure is adapted to the shape of the dust cup cavity 31 and is coaxial with the dust cup cavity 31, so that the dust suction airflow can evenly enter the filter structure after entering the dust cup cavity 31, ensuring a better filtering effect; the filter structure extends along the axial direction of the dust cup cavity 31 to form a part of the first flow path, and the second flow path is located outside the dust cup cavity 31 and at least partially extends along the axial direction of the dust cup cavity 31, so that in the axial direction of the dust cup cavity 31, the first flow path and the second flow path can be roughly parallel, ensuring a more compact structure.

[0078] Further, combined with Figure 3 、 Figure 5 and Figure 6As shown, the filter structure includes a first filter structure 32, a second filter structure 33 and a third filter structure 34. The first filter structure 32 is arranged on the inner side of the dust cup cavity 31 and is arranged in a cylindrical state. The first filter structure 32 is set as a filter cylinder, and its shape is adapted to the shape of the dust cup cavity 31; the second filter structure 33 is arranged on the inner circumference of the first filter structure 32 and is connected to the air outlet side of the first filter structure 32. Preferably, the second filter structure 33 is set as a multi-cone filter; the third filter structure 34 is arranged at one axial end of the dust cup cavity 31 and is connected to the second filter structure 33. The dust cup cavity 31 includes a cavity body and a cavity cover. The cavity cover is arranged at one axial end of the cavity body, and the third filter structure 34 is arranged at the other axial end of the cavity body. Combined Figure 7 As shown in Figure 7 The dashed arrow in the middle represents the airflow direction when the vacuum cleaner device 100 is performing a vacuum cleaning operation. The dust collection airflow can enter the cavity through one side of the cavity, and after being filtered by the first filter structure 32, enter the second filter structure 33. The airflow after secondary filtration by the second filter structure 33 is then filtered by the third filter structure 34 before entering the air inlet end of the suction device 4, ensuring that the airflow enters the suction device 4 after being filtered. Among them, the suction device 4 and the air duct switching structure 1 are both located on the side of the third filter structure 34 that is away from the second filter structure 33. The dust cup cavity 31, the first filter structure 32, the second filter structure 33, and the third filter structure 34 are all coaxially arranged. This makes the suction device 4 and the air duct switching structure 1 occupy less space along the axial direction of the dust cup cavity 31. Therefore, while the volume of the dust cup cavity 31 is sufficiently large, the volume of the entire vacuum cleaner device 100 will not increase.

[0079] Preferably, the suction device 4 includes an axial flow fan, the axial direction of which extends radially along the dust cup chamber 31 and is perpendicular to the axial direction of the filter structure. The axial direction of the axial flow fan is the direction in which the rotational axes of the blades within the axial flow fan extend. Since the axial length of the axial flow fan is longer than its radial length, arranging the axial direction of the axial flow fan radially along the dust cup chamber 31 allows the vacuum cleaner device 100 to be shorter in the axial direction of the dust cup chamber 31 and to be smaller in size.

[0080] Preferably, the suction device 4 and the air duct switching structure are arranged at the same end of the dust cup chamber 31 along its axial direction, so that the suction device 4 and the air duct switching structure 1 are arranged more compactly, and the air duct switching structure 1 is closer to the suction device 4, which can make the state switching control effect better. Figure 3 and Figure 4As shown, the air duct switching structure 1 is arranged near the air inlet end of the axial flow fan and has a reciprocating motion along the axial direction of the dust cup chamber 31. The air duct switching structure 1 and the suction device 4 are arranged side by side at one end of the third filter structure 34, so that the axial space of the dust cup chamber 31 occupied by the air duct switching structure 1 and the suction device 4 is smaller, and the air duct switching structure 1 has sufficient space for movement in the axial direction of the dust cup chamber 31, and the spatial layout within the device body 2 is more reasonable and compact.

[0081] Moreover, the radial projections of the suction device 4 and the air duct switching structure 2 along the dust cup cavity 31 at least partially overlap, so that the suction device 4 and the air duct switching structure 2 occupy less space along the axial direction of the dust cup cavity 31, so that the axial length of the entire vacuum cleaner device 100 can be shorter.

[0082] Specifically, for the layout of the first flow path and the second flow path, a first channel 21 and a second channel 22 are formed in the device body 2, the first channel 21 connects the dust cup assembly 3 and the suction device 4, and the second channel 22 is suitable for connecting the suction device 4 and the dust collection station 200; when the air duct switching structure 1 is in the first working state, the air duct switching structure 1 is in a state of blocking the first channel 21 and connecting 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 in a state of connecting the first channel 21 and blocking the second channel 22; the air flow channel between the dust suction port 24 and the third filtering structure 34 and the first channel 21 together form a first flow path, and the second channel 22 forms a second flow path. When the vacuum cleaner device 100 is performing vacuum cleaning, the airflow flows roughly along the axial direction of the dust cup cavity 31 when filtered through the filtering structure; when the vacuum cleaner device 100 is performing sewage discharge, the airflow can flow along the second channel 22, and most of the second channel 22 is arranged along the axial direction of the dust cup cavity 31. 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 the volume of the entire vacuum cleaner device 100 can be smaller.

[0083] In order to make the air duct switching structure 1 occupy less space while better realizing the switching between the two working states. Specifically, for the air duct switching structure 1, the air duct switching structure 1 includes a first shielding portion 11 and a second shielding portion 12, the first channel 21 has a first opening 211 connected to the suction device 4, and the second channel 22 has a second opening 221 connected to the suction device 4. When the air duct switching structure 1 is in the first working state, the first shielding portion 11 blocks the first opening 211, and the second shielding portion 12 opens the second opening 221. When it is in the second working state, the first shielding portion 11 opens the first opening 211, and the second shielding portion 12 blocks the second opening 221. By controlling the conduction and blocking of the first opening 211 and the second opening 221, the switching between the two working modes is realized, and the operation is simpler.

[0084] Since the axial direction of the axial flow fan is perpendicular to the axial direction of the dust cup chamber 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 relatively to each other along the axial direction of the dust cup chamber 31. By making the first shielding part 11 and the second shielding part 12 move back and forth in a straight line along the axial direction of the dust cup chamber 31, the conduction and blocking of the first opening 211 and the second opening 221 can be achieved.

[0085] The second channel 22 includes a first conductive section extending axially along the dust cup assembly 3, and a second conductive section connecting the first conductive section and the second opening 221. The second conductive section extends laterally from the first conductive section. The length of the first conductive section is longer than that of the second conductive section, allowing the second channel 22 to be better positioned along the outer side of the dust cup cavity 31, resulting in a more compact structure.

[0086] Among them, combined Figure 2 and Figure 6 As shown, the first air vent 23 forms a port of the second channel, and the first air vent 23 and the dust outlet are located in the same plane. When the vacuum cleaner device 100 is placed on the dust collecting station 200, after the dust outlet is connected to the dust collecting station 200, the first air vent 23 can also be better connected and conducted with the dust collecting station 200. Preferably, the dust outlet is located at the front end of the device body 2, and the first air vent 23 is also located at the front end of the device body 2. When the vacuum cleaner device 100 is placed on the dust collecting station 200, the front end of the device body 2 can be connected to the dust collecting station 200. Moreover, the dust outlet can be plugged into the dust collecting station 200 with the dust outlet facing downward. After the cavity cover is opened, the dirt can better fall into the dust collecting station 200.

[0087] Preferably, combined Figure 2 and Figure 11As shown, there are two first air outlets 23, and the vacuum cleaner device also includes an air guide member provided in the device body, the air guide member includes an air guide plate 5 provided in a groove shape, the air guide plate is located outside the dust cup cavity 31, and the second channel is formed between the air guide plate and the dust cup cavity 31. The first air outlet 23 is a port formed on the outer surface of the device body 2 for the second channel. Figure 6 and Figure 11 As shown in Figure 11 The dotted arrow in the middle represents the flow direction of the airflow when the vacuum cleaner device 100 is performing sewage discharge work. Multiple ribs separate the second channel 22 into two branch channels, and the two branch channels are respectively connected to the two first air outlets 23. The two first air outlets 23 are connected to the two docking ports on the dust collecting station 200, so that the suction device 4 is connected to the dust collecting station 200, and the airflow rate is larger, which can effectively improve the sewage discharge efficiency of the dust collecting station 200 to the dust cup assembly 3.

[0088] Among them, a dust suction channel suitable for connecting the dust cup cavity 31 and the outside world is provided on the device body 2. External dirt can be introduced into the dust cup cavity 31 through the dust suction channel. The dust suction port 24 of the dust suction channel is provided 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 provided 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. Therefore, when operating the vacuum cleaner device 100 for cleaning, the operation is easier.

[0089] The first channel 21 and the second channel 22 both have two operating states: open and blocked. Therefore, the first channel 21 and the second channel 22 can operate in four different states. For example, when the first channel 21 is in the open state, the second channel 22 can be in the open state or in the blocked state; and when the first channel 21 is in the blocked state, the second channel 22 can be in the open state or in the blocked state.

[0090] It is understood that if both channels are in an open state, the airflow generated by the suction device 4 will be split, reducing the suction force entering each channel. If both channels are in a blocked state, there will be no continuous airflow entering the air inlet side of the suction device 4, forming a vacuum. The pressure on the air inlet side of the suction device 4 is too low, causing the air inlet side air duct to be squeezed and deformed, or the suction device 4 to overheat and cause damage. Therefore, preferably, the air duct switching structure 1 can be movable to have a first operating state in which the first channel 21 is blocked and the second channel 22 is open, and a second operating state in which the first channel 21 is open and the second channel 22 is blocked. When the suction device 4 is connected to the dust cup assembly 3, the suction device 4 and the dust collecting station 200 are in a blocked state, and the vacuum cleaner equipment 100 can better perform dust collection and cleaning work; and when the suction device 4 and the dust collecting station 200 are connected to the dust cup assembly 3, the suction device 4 and the dust cup assembly 3 are in a blocked state, and the dust collecting station 200 has a better self-cleaning effect on the dust cup assembly 3.

[0091] More preferably, combined Figure 3 and Figure 4 As shown, the first channel 21 has a first opening 211 connected to the suction device 4, and the second channel 22 has a second opening 221 connected to the suction device 4; when in the first working state, the first shielding portion 11 blocks the first opening 211, and the second shielding portion 12 opens the second opening 221; when in the second working state, the first shielding portion 11 opens the first opening 211, and the second shielding portion 12 blocks the second opening 221, so that only one of the two channels can be in a conducting state, so that the airflow generated by the suction device 4 can only flow along one channel, which can avoid the phenomenon of both channels being connected or both channels being blocked, and can better protect the vacuum cleaner device 100.

[0092] Of course, in another embodiment, only one of the first shielding portion 11 and the second shielding portion 12 may be provided, and the movement of the single shielding portion can realize the opening and blocking of the two openings, thereby realizing the switching between the first working state and the second working state. However, by having the first shielding portion 11 and the second shielding portion 12 respectively block and open the first opening 211 and the second opening 221, the movement stroke of the first shielding portion 11 and the second shielding portion 12 can be shortened, and the internal space occupied can be reduced, thereby achieving a more compact structure.

[0093] The first shielding portion 11 and the second shielding portion 12 can be independently configured, meaning that the first shielding portion 11 and the second shielding portion 12 can move differently. For example, after or before the first shielding portion 11 blocks the first opening 211, the second shielding portion 12 can move to open the second opening 221; alternatively, after or while the first shielding portion 11 opens the first opening 211, the second shielding portion 12 can move to block the second opening 221. This allows for greater flexibility in the movement of the first and second shielding portions 11, 12 without affecting each other.

[0094] Preferably, the first shielding portion 11 and the second shielding portion 12 are arranged in a linked manner, that is, the first shielding portion 11 and the second shielding portion 12 move synchronously. In the first operating state, the first shielding portion 11 blocks the first opening 211 while the second shielding portion 12 opens to the second opening 221. In the second operating state, the second shielding portion 12 blocks the second opening 221 while the first shielding portion 11 opens to the first opening 211. Specifically, the air duct switching structure 1 also includes a first transmission member 13 movably disposed within the device body 2. The first transmission member 13 connects the first shielding portion 11 and the second shielding portion 12. The first transmission member 13 moves in response to an external force, driving the first shielding portion 11 and the second shielding portion 12 to move together. The first transmission member 13 can be moved manually, by a driving device, or by the dust collection station 200, thereby switching the operating states of the first shielding portion 11 and the second shielding portion 12, thereby better ensuring the operating performance of the vacuum cleaner device 100.

[0095] The following specifically describes how, when the first shielding portion 11 and the second shielding portion 12 are arranged in linkage, the first shielding portion 11 and the second shielding portion 12 can be driven to move together by controlling the movement of the first transmission member 13 .

[0096] Specifically, the first transmission member 13 includes a first transmission rod 131, and the first shielding portion 11 and the second shielding portion 12 are arranged at intervals along the length of the first transmission rod 131. The first transmission rod 131 is movably sleeved within the first opening 211 and the second opening 221. The first opening 211 and the second opening 221 are arranged opposite each other along the second direction. When the first transmission rod 131 reciprocates in the second direction, the first shielding portion 11 and the second shielding portion 12 can move together to respectively enter the first working state and the second working state.

[0097] Furthermore, the first shielding portion 11 includes a first shielding plate, which protrudes from the first transmission rod 131 in a radial direction thereof. The second shielding portion 12 includes a second shielding plate, which protrudes from the first transmission rod 131 in a radial direction thereof. The first shielding plate and the second shielding plate are respectively located on opposite sides of the first opening 211 and the second opening 221. When the first shielding plate approaches 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 toward the second opening 221. Both the first shielding plate and the second shielding plate are generally flat plates, with the first shielding plate being sized to match the first opening 211, and the second shielding plate being sized to match the second opening 221. Preferably, the first opening 211 and the second opening 221 are both circular and have the same diameter.

[0098] At least one of the first and second shielding plates is detachably connected to the first transmission rod 131 to facilitate installation and removal of the air duct switching structure 1. Preferably, the first shielding plate is integrally formed with the first transmission rod 131, while the second shielding plate is detachably attached to the first transmission rod 131. This reduces the number of assembly parts and facilitates assembly and disassembly. During assembly, the first transmission rod 131 is first inserted through the first opening 211 toward the second opening 221, and the second shielding plate is then placed over the first transmission rod 131 to secure the structure.

[0099] Moreover, if Figure 4 As shown in , the air duct switching structure 1 also includes a first seal 14, which is sleeved on the outer peripheral side of the first baffle. When in the first working state, the first baffle is located at the first opening 211, and at least part of the first seal 14 is located in the gap between the first opening 211 and the first baffle. A first air guide surface 141 is formed on the first seal 14. In the direction of air flow, the first guide surface is located upstream of the first opening 211; wherein, in the axial direction of the first opening 211 and in the direction of air flow, the outer diameter of the first guide surface is gradually increased. The airflow flowing out of the dust cup assembly 3 can be better guided by the first air guide surface 141 to flow toward the direction of the first opening 211, thereby avoiding the airflow directly converging and impacting the side around the mouth of the first opening 211, thereby preventing energy loss. Specifically, the first sealing member 14 is roughly conical in shape, and the first air guide surface 141 is formed on the outer surface of the cone. An elastic sealing arm is also provided at the end of the large end surface of the cone-shaped structure. When the first baffle plate is sealed at the first opening 211, the elastic sealing arm and the cone-shaped structure can be respectively located on both sides of the first opening 211, and the connection between the elastic sealing arm and the cone-shaped structure is clamped and sealed with the mouth of the first opening 211 to ensure a better sealing effect.

[0100] Among them, such as Figure 4 As shown in , the air duct switching structure 1 also includes a second sealing member 15, which is sleeved around the outer periphery of the second shielding plate. When in the second operating state, the second shielding plate is located at the second opening 221, and at least a portion of the second sealing member 15 is located in the gap between the second opening 221 and the second shielding plate. The second sealing member 15 is also provided with an elastic sealing arm, which is located on the first side of the second opening 221. When in the second operating state, the elastic sealing arm elastically deforms to extend from the first side of the second opening 221 to the second side of the second opening 221, thereby forming a seal with the second opening 221. When the second shielding plate blocks the second opening 221, the second opening 221 can be better sealed.

[0101] Furthermore, a first guide protrusion 17 is provided within the device body 2, extending from the first opening 211 toward the second opening 221. The first transmission rod 131 is hollow, with one end movably sleeved onto the outside of the first guide protrusion 17. During movement of the first transmission rod 131, the first guide protrusion 17 provides guidance, making the movement of the first transmission rod 131 more stable and less prone to shaking. This allows for more accurate alignment of the first and second shielding plates during blocking, resulting in a better blocking effect.

[0102] In one embodiment, the air duct switching structure 1 further includes a second transmission member 16, which is connected to the first transmission member 13. When the second transmission member 16 is moved by an external force, it drives the first transmission member 13 to move, thereby switching the first shielding portion 11 and the second shielding portion 12 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. Moreover, the second transmission member 16 allows the dust collection station 200 to better act on the air duct switching structure 1, thereby facilitating the docking of the vacuum cleaner device 100 and the dust collection station 200 to switch the working state of the air duct switching structure 1, making operation more convenient.

[0103] Further, combined with Figures 4 to 6As shown, the second transmission member 16 includes a second transmission rod 161, and a first connector 162 and a second connector 163 respectively provided at both ends of the second transmission rod 161. The first connector 162 is connected to the first transmission member 13, and the first connector 162 and the second connector 163 are detachably connected to the second transmission rod 161 to facilitate assembly. When the vacuum cleaner device 100 is adapted to be connected to the dust collection station 200 or after being connected, the second connector 163 is adapted to move under the action of the trigger portion 201 on the dust collection station 200, and drive the second transmission rod 161, the first connector 162 and the first transmission member 13 to move together, so that the first shielding portion 11 and the second shielding portion 12 can switch between the first working state and the second working state. Among them, the second connecting head 163 is arranged close to the outside of the device body 2, so that when the vacuum cleaner device 100 is connected to the dust collecting station 200 or after being connected, the trigger part 201 on the dust collecting station 200 can act on the second connecting head 163, prompting 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 along the second direction.

[0104] Preferably, the second transmission rod 161 is arranged to extend axially along the dust cup chamber 31, the first transmission member 13 is located at one axial end of the dust cup assembly 3, and the second connector 163 is located at the other axial end of the dust cup assembly 3. The first transmission rod 131 and the second transmission rod 161 are arranged in parallel and both extend axially along the dust cup chamber 31. Similarly, they occupy less radial space in the dust cup chamber 31 to ensure a more compact structure. At least a portion of the second connector 163 can be exposed from the plane where the first air outlet 23 is located, so that when the vacuum cleaner device 100 is connected to the dust collection station 200, the trigger part 201 on the dust collection station 200 can better act on the second connector 163 to drive the entire second transmission member 16 to move better.

[0105] Furthermore, a guide groove 25 is formed within the device body 2, extending from the first opening 211 toward the second opening 221. The second transmission rod 161 is movably disposed within the guide groove 25. The guiding action of the guide groove 25 provides greater stability for the second transmission rod 161 during movement. Multiple partitions are spaced apart within the guide groove 25, and the second transmission rod 161 is movably disposed between the partitions to ensure better guidance. Furthermore, a limiting protrusion may be protruding from the second transmission rod 161, which can act against one or more of the partitions to limit the travel of the second transmission rod 161, thereby better controlling the movement of the first and second shielding plates and preventing excessive movement that could render the plate unresettable.

[0106] Furthermore, if Figure 4As shown in , the air duct switching structure 1 also includes an elastic telescopic member 18, which can be configured as a telescopic spring, with both ends of the elastic telescopic member 18 abutting between the second transmission rod 161 and the second opening 221. When the vacuum cleaner device 100 is placed on the dust collection station 200, under the action of the triggering portion 201 of the dust collection station 200, the second transmission member 16 is prompted to move. At this time, the first baffle is set to block the first opening 211, and the second baffle is set to open the second opening 221. The elastic telescopic member 18 is in an elastic energy storage state (such as an extended or compressed state), and the vacuum cleaner device 100 is in a sewage discharge state. When the vacuum cleaner device 100 is removed from the dust collection station 200, the second transmission member 16 is no longer affected by the triggering portion 201. Under the action of the elastic restoring force of the elastic telescopic member 18, the first transmission rod 131 is reset, so that the first baffle opens the first opening 211 and the second baffle blocks the second opening 221, and the vacuum cleaner device 100 enters the dust collection and cleaning state. Therefore, when the vacuum cleaner device 100 is placed on the dust collecting station 200, the air duct switching structure 1 can automatically enter the first working state, so that the suction device 4 can be connected to the dust collecting station 200, so that the dust cup assembly 3 can discharge sewage; after the vacuum cleaner device 100 is removed from the dust collecting station 200, the air duct switching structure 1 can automatically enter the second working state, so that the suction device 4 can be connected to the dust cup assembly 3, and the vacuum cleaner device 100 automatically enters the dust collection and cleaning state, making the vacuum cleaner device 100 more convenient to use, and the user does not need to perform the switching operation of the air duct switching structure 1, so it is more worry-free to use.

[0107] The device body 2 can have a variety of shapes to meet the needs of different users. In one embodiment, the device body 2 is generally arranged in a long, cylindrical shape. The front end of the device body 2 is provided with a dust suction port 24, the rear end of the device body 2 is provided with a handle, and the dust cup assembly 3 and the suction device 4 are arranged in a sequential manner along the front and back direction of the device body 2. The front and back here refer to the end closest to the surface to be cleaned being the front and the end facing away from the surface to be cleaned being the rear when the vacuum cleaner device 100 is in normal use.

[0108] The utility model also provides a vacuum cleaner system 1000, which is combined with Figures 9 to 11 As shown, the vacuum cleaner system 1000 includes a dust collecting station 200 and the above-mentioned vacuum cleaner device 100, wherein the dust collecting station 200 can be connected to the vacuum cleaner device 100. When the dust collecting station 200 and the vacuum cleaner device 100 are connected or after being connected, the suction device 4 of the vacuum cleaner device 100 can form a negative pressure in the dust collecting station 200 to suck the dirt at the vacuum cleaner device 100 into the dust collecting station 200, so as to achieve self-cleaning of the vacuum cleaner device 100.

[0109] Preferably, the working mode of the vacuum cleaner device 100 can be switched through the air duct switching structure 1 on the vacuum cleaner device 100, so that the suction device 4 of the vacuum cleaner device 100 can be connected to the dust cup assembly 3 to perform cleaning work, and the suction device 4 of the vacuum cleaner device 100 can be connected to the dust collecting station 200, so that a negative pressure can be formed in the dust collecting station 200, and then the suction device 4 can form a negative pressure in the dust collecting station 200, and then the dirt in the dust cup assembly 3 is sucked into the dust collecting station 200, thereby realizing self-cleaning of the vacuum cleaner device 100.

[0110] Combine Figure 10 As shown in FIG, when the vacuum cleaner device 100 is docked with the dust collection station 200, the trigger portion 201 on the dust collection station 200 acts on the second connector 163 on the second transmission rod 161, driving the second transmission rod 161 to move backward, driving the second shielding plate to open the second opening 221, and driving the first shielding plate to block the first opening 211, so that the suction device 4 can be connected to the dust collection station 200 through the second channel 22. The action portion can be configured as a supporting protrusion, which can at least partially extend into the guide groove 25 to act on the second connector 163. When the vacuum cleaner device 100 is placed on the dust collection station 200, the air duct switching structure 1 automatically switches the working state, allowing the suction device 4 to automatically connect to the dust collection station 200, eliminating the need for manual adjustment by the user, making operation more worry-free. Furthermore, the dust collection station 200 does not need to be equipped with a power device to discharge the dust cup assembly 3, resulting in a simpler structure and lower cost.

[0111] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
