Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners and their components, specifically relating to dust cup (dust collection unit) covers, vacuum cleaners, base stations, and vacuuming systems. Background Technology

[0002] Vacuum cleaners are now widely used in daily life, providing users with efficient and convenient cleaning services. Currently, the most popular handheld vacuum cleaners are usually equipped with a base station, which can store the vacuum cleaner and, when stored, charge the battery pack and empty the dust cup to remove collected dirt. However, after emptying, users often need to manually close the dustbin lid, which is cumbersome and easily gets their hands dirty.

[0003] To address this issue, patent document PCT / KR2021 / 095072 discloses a vacuum cleaner base station with a lid-opening unit. This unit includes a push protrusion, a lid-opening motor, and a gear mechanism. The motor drives the gear mechanism, which in turn drives the push protrusion to open and close the lid. However, this solution requires an additional motor for closing the lid, resulting in high costs and a complex structure.

[0004] Chinese patent document CN117617816A discloses a cleaning system and base station. The system includes a closing mechanism mounted on the base station. This closing mechanism comprises a drive component and a closing component connected to each other. The drive component causes the closing component to tend to stay on a preset movement trajectory. The closing mechanism has a first state and a second state. In the first state, the closing component is held on the preset movement trajectory. In the second state, the closing component moves to one side of the preset movement trajectory under external force. When the handheld device moves away from the carrier along the preset movement trajectory, the closing mechanism is in the second state, and the closing component contacts the dust collection cover, causing the dust collection cover to close the dust outlet. In this solution, the drive component is an elastic element, thus eliminating the need for a motor. However, in this solution, after the vacuum cleaner is placed on the base station, the elastic element of the closing mechanism needs to be constantly and significantly compressed to keep the closing mechanism pressed and held on one side of the movement trajectory. The elastic element can only recover after the vacuum cleaner leaves the base station. However, the time the vacuum cleaner is in the storage position on the base station far exceeds the time it is away from the base station. The vacuum cleaner is typically used for less than an hour a day without being on the base station. Therefore, the elastic element of the closing mechanism in this solution will be in a compressed and tense state for a long time, resulting in a significantly shortened lifespan and easy failure. Utility Model Content

[0005] This invention is made to solve the above-mentioned problems, and aims to provide a dust cup cover, a vacuum cleaner, a base station, and a vacuuming system, which can close the cover stably and reliably through a simple structure.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] <Vacuum Cleaning System>

[0008] This utility model provides a vacuuming system, including a vacuum cleaner and a base station. The vacuum cleaner includes a dust cup and a dust cup cover. The dust cup cover has a closed state with the dust cup cleaning port closed and an open state with the dust cup cleaning port open. The base station is used to store the vacuum cleaner and to open and clean the vacuum cleaner. The base station is provided with an abutment corresponding to the dust cup cover on the path (departure path) of the vacuum cleaner leaving the storage position. The dust cup cover includes: a cover body, which is rotatably covered at the dust cup cleaning port; and a closing mechanism, which is provided on the cover body and corresponds to the abutment, having: a movable end that can move relative to the cover body in the closing direction after being abutted by the abutment, and a closing end that can be driven by the movable end to push the cover body in the closing direction.

[0009] The beneficial effects of the above solution are as follows: because the closing mechanism is located on the vacuum cleaner rather than on the base station, the closing mechanism only needs to be abutted by the base station's abutment when the vacuum cleaner leaves the station to close the cover. In other scenarios, such as vacuuming and cleaning, the closing mechanism does not need to be abutted by the base station's abutment. Therefore, both the closing mechanism and the base station abutment can remain in a normal, non-pressurized state for a long time, which effectively improves the service life of the closing mechanism and the base station abutment. Moreover, the structure is simple and can close the cover stably and reliably.

[0010] <Dust Cup Lid>

[0011] This utility model provides a dust cup cover, which has a closed state when the dust cup cleaning port is closed and an open state when the dust cup cleaning port is open. It includes: a cover body, which is rotatably covered at the dust cup cleaning port; and a closing mechanism, which is disposed on the cover body and has: a movable end that can move relative to the cover body in the closing direction after being abutted by an external force, and a closing end that can be driven by the movable end to push the cover body in the closing direction.

[0012] The beneficial effects of the above solution are as follows: because the closing mechanism is located on the dust cup lid of the vacuum cleaner rather than on the base station, the closing mechanism only needs to be closed by the base station's resistance force (external force) when the vacuum cleaner leaves the station. In other scenarios, such as vacuuming and cleaning, the closing mechanism does not need to be resisted by external force. Therefore, the closing mechanism can remain in a normal, non-pressurized state for a long time, effectively extending the service life of the closing mechanism. Moreover, the structure is simple and can close the lid stably and reliably.

[0013] <base station>

[0014] This utility model provides a base station, which has an abutment corresponding to the dust cup cover on the path of the vacuum cleaner leaving the storage position, and applies external force to the <dust cup cover> described above to close the cover.

[0015] The beneficial effects of the above solution are as follows: Since this base station corresponds to the aforementioned <dust cup cover>, it has the same beneficial effects as the <dust cup cover>. Specifically, the base station's contact piece only needs to contact the closing mechanism to close the cover when the vacuum cleaner leaves the station. In other scenarios, such as vacuuming and cleaning, the contact piece does not need to contact the closing mechanism. Therefore, the base station's contact piece can remain in a normal, non-pressurized state for a long time, effectively extending the service life of the base station's contact piece. Moreover, the structure is simple and can close the cover stably and reliably.

[0016] Vacuum Cleaner

[0017] Vacuum cleaner, including the dust cup lid mentioned above.

[0018] The beneficial effects of the above solution are as follows: the vacuum system includes the dust cup cover mentioned above, and therefore has the same beneficial effects as the dust cup cover mentioned above.

[0019] In addition, the following optional solutions may also be included in the <vacuum cleaning system>, <dust cup cover>, <base station>, and <vacuum cleaner> described above:

[0020] In this invention, the dust cup cover or vacuum cleaner further includes: a clearance area, capable of accommodating at least a portion of the contact surface of the contact member during cleaning, and spaced a certain distance from the contact member, so that the contact member of the base station avoids the cleaning and opening rotation range of the cover opening body; as the vacuum cleaner leaves the base station, the clearance area moves away from the contact member, the movable end contacts the contact member, and drives the closing end to push against the closing cover body. The clearance area on the vacuum cleaner may not be provided on the dust cup cover, for example, it may be provided near the battery pack near the dust cup cover, forming a recessed area corresponding to the contact member on the surface of the battery pack.

[0021] Preferably, in this invention, the clearance area on the dust cup cover is a recessed area near the opening and closing hinge of the cover body. This recessed area includes, but is not limited to: an area formed between the two rotating lugs of the cover body, an area formed above the hinge of the cover body, or an area formed below the hinge of the cover body. The closer to the closing hinge, the easier it is to close the cover quickly. In this solution, the base station's contact member does not contain any driving component; the driving component is located in the closing mechanism of the dust cup cover.

[0022] Preferably, in this invention, the closing mechanism includes: a movable cover movably mounted on the cover body, an elastic element installed between the movable cover and the cover body, and a limiting element restricting the range of motion of the movable cover. The elastic element buffers the impact force of the contact element on the dust cup cover along the closing path during entry and exit. The movable cover or the inner end of the elastic element that contacts or is close to the cover body can serve as the closing end. When the cover is not closed, the elastic element does not need to move (leave its initial position or come into contact with the base station and be subjected to force). Therefore, when the cover is not closed, the elastic element can be in a natural, uncompressed state or in a state with very little compression, thus not negatively affecting the lifespan of the elastic element and the closing mechanism. In this invention, "or" indicates selecting at least one of at least two options.

[0023] Preferably, in this invention, the movable cover is configured such that, during entry and exit from the station, a ramp is provided on the upper and lower sides of the corresponding abutment to guide the abutment from the side of the movable cover (relative movement; in reality, the movable cover moves during entry and exit while the abutment remains stationary) into the middle area of ​​the outer side of the movable cover. This prevents the abutment from getting stuck or even jammed on the side of the movable cover and reduces the abutment force exerted by the abutment on the movable cover in the non-closing direction, concentrating the abutment force on the closing direction. Furthermore, chamfers can be added at the corners of the movable cover to further facilitate the smooth entry of the abutment into the middle area of ​​the outer side of the movable cover. The middle area refers to the area where the abutment force is most advantageous for closing the cover.

[0024] Preferably, in this invention, the spatial position of the abutting component on the base station is fixed, and its spatial position when abutting the dust cup cover does not exceed its spatial position when not abutting. The abutting component is a self-rotating wheel or a fixed component. A fixed spatial position means that the position of the abutting component in the three-dimensional space remains unchanged. Even if the wheel rotates, its overall spatial position and posture remain unchanged, without movement or swinging to other spatial positions during abutment. When the abutting component is a fixed component, it does not even rotate and cannot move. Fixed components do not rotate and have no pivot, making the structure more stable and reliable. The wheel rotates to minimize rolling friction, not to close the cover.

[0025] Preferably, in this invention, the fixing member is disposed above the clearing opening of the base station body and protrudes from the surface of the base station body that contacts the cover body; or, the fixing member is a corner area on the outer surface of the clearing opening of the base station body. Since the abutment member only needs to apply external force to the closing mechanism when the vacuum cleaner leaves the station, and when the vacuum cleaner is lifted away by the user, the user will naturally push the vacuum cleaner towards the base station based on the guide rail of the base station (which is widely used in the prior art), the abutment member can be a fixed corner area on the base station housing that matches the closing mechanism, without needing to protrude particularly from the outer surface of the base station. The corner area can abut against the closing mechanism when leaving the station.

[0026] Preferably, in this invention, the abutment and the dust cup lid are in rolling contact; the rolling element is disposed on the dust cup lid or the abutment, and the rolling element includes, but is not limited to, rollers and balls. This minimizes friction when the abutment contacts the lid-closing mechanism.

[0027] Preferably, in this invention, the surface of the abutment member is provided with a removable, impact-resistant, and friction-resistant protective layer. This further reduces wear and tear and facilitates user maintenance, making it particularly suitable for situations where the abutment member is a fixed component.

[0028] <Vacuum Cleaning System>

[0029] Furthermore, this utility model also provides a vacuuming system, including: a vacuum cleaner as described in any of the above-mentioned <vacuum cleaners>; and a base station for storing the vacuum cleaner and cleaning it. This vacuuming system includes the <vacuum cleaners> mentioned above, and therefore has the same beneficial effects as the <vacuum cleaners> described above. Attached Figure Description

[0042] The following description, in conjunction with the accompanying drawings, details the specific implementation schemes of the dust cup cover, vacuum cleaner, base station, and vacuuming system involved in this utility model.

[0043] <Example>

[0044] like Figures 1-3 As shown, the vacuuming system 1000 includes a vacuum cleaner 100 and a base station 200. The vacuum cleaner 100 is used to collect dirt from the surface to be cleaned, and has a vacuuming state for collecting dirt from the surface to be cleaned, and a cleaning state for removing the collected dirt. The base station 200 is used to store the vacuum cleaner 100 and to open the cover of the vacuum cleaner 100 for cleaning.

[0045] In this embodiment, a cordless handheld vacuum cleaner 100 is used. The vacuum cleaner 100 includes a vacuum cleaner body 10, an extension tube 20, and a nozzle 30. The vacuum cleaner body 10 is used to generate negative pressure to suck up and collect dirt from the surface to be cleaned in suction mode. It includes a housing 11, a fan 12, a battery pack 13, a dust collection unit 14, and a cover closing mechanism 15.

[0046] The housing 11 is used to mount the electric fan 12, the battery pack 13, and the dust collection unit 14. The housing 11 is provided with a handle 111 for the user to hold.

[0047] The electric fan 12 is used to generate negative pressure, thereby providing suction to form an intake airflow. Its air inlet is located near the upper part of the dust collection unit 14.

[0048] The battery pack 13 is used to supply power. In this embodiment, the battery pack 13 supplies power to the electric fan 12, the extension tube 20, and the suction nozzle 30. Long strip-shaped sliders 131 are fixed on the left and right sides of the bottom of the battery pack 13.

[0049] The dust collection unit 14 is used for dust and gas separation and dirt collection. In this embodiment, the dust collection unit 14 can separate dirt from the intake airflow and collect it at the bottom of the cup through cyclone separation. Figures 3-6 As shown, the dust collection unit 14 includes a dust cup 141, a dust cup cover 142, and a cover lock 143.

[0050] The dust cup 141 has a dust cup cleaning port 141a at its bottom. The dust cup 141 also has a two-stage dust collection unit inside, which is existing technology and will not be described in detail here.

[0051] The dust cup cover 142 has a closed state with the dust cup cleaning port 141a closed and an open state with the dust cup cleaning port 141a open. The dust cup cover 142 includes a cup bottom frame 142a, a cover body 142b, a clearance area 142c, and a cover buckle 142d.

[0052] A cup bottom frame 142a is installed at the bottom of the dust cup 141, and the inner part of the cup bottom frame 142a is arranged around the inner wall of the dust cup 141. In this embodiment, as shown... Figure 4 As shown, the outer surface of the upper side of the cup bottom frame 142a is recessed inward (towards the thickness direction) to form a recess 142a-1.

[0053] The cover body 142b is rotatably mounted on the cup bottom frame 142a and can be opened and closed over the dust cup cleaning port 141a. When the cover is closed, the cup bottom frame 142a and the cover body 142b are sealed together by a sealing element, thereby closing the dust cup cleaning port 141a. Two rotating ears 142b-1 above the dust cup cleaning port 141a are spaced apart in the recess 142a of the cup bottom frame 142a, and the two rotating ears 142b-1 can rotate around two rotating shafts 142b-2 mounted on the cup bottom frame 142a.

[0054] like Figure 9 As shown, the clearance area 142c is a recessed area in the recess 142a located between the two rotating lugs 142b-1. This clearance area 142c can accommodate at least a portion of the contact surface of the contact member 220 on the base station 200 during the clearing process, and is spaced a certain distance from the contact member 220, so that the contact member 220 avoids the clearing and opening rotation range of the opening body 142b.

[0055] A section extends from the lower part of the cover body 142b to form a cover buckle 142d. The inner protrusion of the cover buckle 142d forms an L-shaped buckle that matches the cover lock 143 on the outer surface of the dust cup 141.

[0056] The cover lock 143 is located on the outer bottom of the cup base frame 142a. In the vacuuming state, it engages with the cover buckle 142d, locking the cover body 142b and thus sealing the dust cup cleaning port 141a. The cover lock 143 contains a spring. Figures 4-5As shown in Figures 10-12, the left end of the cover lock 143 serves as the unlocking end. When pressed by an external force, the right end can be lifted away from the outer wall of the cup bottom frame 142a, thereby unlocking the cover buckle 142d. After unlocking, the cover body 142b can be rotated away from the closed (closed) position by an external force (e.g., base station negative pressure).

[0057] A closing mechanism 15 is disposed on the cover body 142b, corresponding to the abutment member 220. The closing mechanism 15 has a movable end that can move relative to the cover body 142b in the closing direction after being abutted by the abutment member 220, and a closing end that can be driven by the movable end to push the cover body 142b in the closing direction. As the vacuum cleaner 100 leaves the base station 200, the clearance area 142c moves away from the abutment member 220, the movable end contacts the abutment member 220, and drives the closing end to push and close the cover body 142b.

[0058] Specifically, in this embodiment, as Figures 3-6 As shown, the closing mechanism 15 includes a movable cover 151, an elastic element 152, and a limiting element 153.

[0059] The movable cover 151 is movably mounted on the cover body 142b. The exposed end of the movable cover 151 away from the cover body 142b serves as the movable end. The movable cover 151 or the elastic member 152 contacts or approaches the inner end of the cover body 142b as the closing end. Further, in this embodiment, the movable cover 151 is configured such that, when the vacuum cleaner 100 enters and leaves the station, a ramp 151a is provided at the upper and lower sides of the abutment member 220, which can guide the abutment member 220 from the side of the movable cover 151 into the middle area 151b of the exposed end of the movable cover 151 (the movable cover 151 moves, the abutment member 220 remains stationary). This prevents the abutment member 220 from getting stuck on the side of the movable cover 151 and reduces the abutting force of the abutment member 220 on the movable cover 151 in the non-closing direction, so that the abutting force of the abutment member 220 is concentrated in the closing direction. The middle area 151b refers to the area where the abutting force is most advantageous for closing the cover.

[0060] An elastic element 152 is installed between the movable cover 151 and the cover body 142b. The elastic element 152 is a spring, and the axis of the spring is aligned with the thickness direction of the cover body 142b. It can provide slight axial support to the movable cover 151 so that the movable cover 151 is in a position that protrudes relative to the outer surface of the cover body 142b when it is not pushed by an external force.

[0061] The limiting member 153 is used to limit the range of motion of the movable cover 151 (the distance of motion relative to the cover body 142b in the closing direction). The inner end of the side wall of the movable cover 151 extends into the slot 153a of the limiting member 153. The slot 153a is provided on the cover body 142b and extends along the closing direction, limiting the closest distance of the movable cover 151 to the cover body 142b in the closing direction. The limiting member 153 also includes a baffle 153b, which is installed on the outer end of the slot 153a, limiting the farthest distance of the movable cover 151 from the cover body 142b in the closing direction.

[0062] The base station 200 is matched with the vacuum cleaner 100, allowing the vacuum cleaner 100 to be parked, stored / organized, and charged. It can generate a cleaning airflow based on an electric fan to open the vacuum cleaner 100 for cleaning, removing dirt contained in the vacuum cleaner body 10. The base station 200 includes a base station body 210, a base station electric fan, a contact part 220, and a charger.

[0063] like Figures 6-8 As shown in Figures 10-12, the base station body 210 has a hollow structure with a placement area 211 at the top. The outlet of the placement area 211 is connected to a dust bag. Below the dust bag is a base station filter unit for further cleaning airflow. The base station filter unit is connected to the base station exhaust duct, through which clean airflow is discharged. The placement area 211 matches the vacuum cleaner body 10, and its outer surface is provided with a sealing ring 211a that can seal around the bottom frame 142a of the contact cup, thereby sealing and connecting the dust collection unit 14 with the base station body 210 in the cleaning state. The placement area 211 is provided with a protruding push block 211b. When the dust cup 141 enters the placement area 211 (the dust cup 141 contacts the outer surface of the placement area 211), the push block 211b presses the cover lock 143, unlocking the dust cup cover 142.

[0064] Two entry / exit guide grooves 212 are formed on the base station body 210 above the placement area 211, corresponding to the two sliders 131 of the battery pack 13. These grooves guide and position the vacuum cleaner 100 as it approaches and moves downwards into the placement area 211 or upwards out of the placement area 211 along the base station body 210. The path of the vacuum cleaner 100 into the placement area 211 forms the entry path, and the path of the vacuum cleaner 100 out of the placement area 211 forms the exit path. Figure 10 As shown, after the vacuum cleaner 100 enters along the base station body 210 and is stably placed in the placement area 211, the vacuum cleaner 100 is in the storage position.

[0065] The base station electric fan is used to create a negative pressure and airflow for cleaning, thereby transferring the dirt collected in the vacuum cleaner body 10 to the dust bag through the airflow.

[0066] The abutment 220 is positioned on the departure path of the vacuum cleaner 100 as it leaves the storage position, corresponding to the dust cup cover 142. In this embodiment, the abutment 220 is positioned above the cleaning opening 211c of the placement area 211, and includes a shaft 221 and a wheel 222. The wheel 222 can rotate around the shaft 221. The rotation of the wheel 222 minimizes the rolling friction between the abutment 220 and the cover closing mechanism 15, and is not intended to close the cover in the closing direction. Even when the wheel 222 rotates, the position of the abutment 220 in the three-dimensional space remains unchanged; it will not move or swing to other spatial positions with the abutment closing mechanism 15. Regardless of whether the vacuum cleaner 100 is in the departure state, the entry state, or the storage position, the three-dimensional spatial position of the abutment 220 remains unchanged.

[0067] The charger's output terminal is a spring pin. When the vacuum cleaner body 10 is placed on the base station 200, the contact piece of the battery pack 13 contacts the spring pin to connect and start charging.

[0068] like Figures 1-12 As shown, based on the above structure, the specific opening and closing process of the vacuum system 1000 provided in this embodiment is as follows:

[0069] After the user finishes collecting dirt from the surface to be cleaned using the vacuum cleaner 100, the vacuum cleaner 100 is moved to the vicinity of the base station 200 and lifted. The sliders 131 on both sides of the battery pack 13 are aligned with the two guide slots 212 on the base station 200 and inserted. The vacuum cleaner 100 slides down the entry path into the placement area 211. As it slides down, the movable cover 151 of the closing mechanism 15 moves to contact the abutment 220. Under the pushing force of the abutment 220, the elastic member 152 is compressed, causing the movable cover 151 to retract inward to be basically flush with the cover body 142b. The vacuum cleaner 100 thus smoothly passes through the area where the abutment 220 is located and finally slides down to the storage position.

[0070] When in the storage position, both the lid body 142b and the closing mechanism 15 face the emptying opening 211c; the clearance area 142c above the closing mechanism 15 faces the abutment 220 and is spaced a certain distance from the abutment 220, so the dust collection unit 14 does not contact the abutment 220. At the same time, the lid lock 143 is pressed by the push block 211b, and the dust cup lid 142 is in the unlocked state.

[0071] Subsequently, the base station fan is turned on by the user or automatically activated by a sensor. The cover body 142b is rotated away from the closed position by the negative pressure during cleaning and opens to a certain angle. The cleaning airflow carries the dirt collected inside the vacuum cleaner body 10 through the cleaning opening 211c into the dust bag, where it is further filtered by the base station filter unit. The clean airflow is then discharged through the exhaust channel. After a period of cleaning, the base station fan automatically shuts off, the negative pressure during cleaning disappears, and the cover body 142b rotates back to be close to the dust cup 141.

[0072] Next, when the user needs to use the vacuum cleaner 100, they lift the vacuum cleaner 100 upwards along the base station 200 using the handle 111, allowing the vacuum cleaner 100 to slide upwards along the exit path and leave the placement area 211. As it slides upwards, the clearance area 142c moves away from the abutment member 220, and the movable cover 151 of the closing mechanism 15 moves upwards to contact the abutment member 220. Under the pushing force of the abutment member 220, the elastic member 152 is compressed, and the inner ends of the movable cover 151 and the elastic member 152 push against the cover body 142b in the closing direction, causing the cover body 142b to move in the closing direction. The cover latch 142d then engages with the cover lock 143, locking the cover body 142b in the closed position. At the same time, the movable cover 151 retracts inwards to be basically flush with the cover body 142b, thus smoothly passing through the area where the abutment member 220 is located, and finally the vacuum cleaner 100 slides upwards and leaves the base station 200.

[0073] The above embodiments are merely illustrative examples of the technical solution of this utility model. The vacuum cleaner involved in this utility model is not limited to the content described in the above embodiments, but is subject to the scope defined by the claims. Any modifications, additions, or equivalent substitutions made by those skilled in the art based on these embodiments are within the scope of protection claimed by the claims of this utility model.

[0074] In the above embodiments, the inner part of the cup bottom frame is arranged around the inner wall of the dust cup, forming a step and blocking part of the bottom cross-sectional area of ​​the dust cup. In this invention, the cup bottom frame can also be placed outside the primary dust chamber, thus avoiding the formation of a step and obstruction. The corresponding recess and avoidance area can still be formed on the external cup bottom frame.

[0075] In addition, in the above embodiments, the cup bottom frame is fixedly installed at the bottom of the dust cup and cannot be rotated. In this embodiment, the cup bottom frame can also be rotatably installed at the bottom of the dust cup, and the corresponding cup bottom frame can also rotate away from the dust cup.

[0076] Furthermore, in the above embodiments, the clearance area is formed on the bottom frame of the cup. In this invention, the clearance area can also be formed on the battery pack, with a recessed area corresponding to the abutment provided on the outer shell of the battery pack.

[0077] In addition, in the above embodiments, the base station has a built-in electric fan. In this invention, the base station may also omit the electric fan, and instead utilize the electric fan inside the vacuum cleaner body to create a cleaning airflow from the vacuum cleaner body into the dust bag.

[0078] Furthermore, in the above embodiments, the abutment is a self-rotating wheel. In this invention, the abutment can also be a fixed component, such as a fixed cam. The surface of the abutment can also be provided with a removable, impact-proof, and friction-resistant protective layer. This can further reduce wear and tear and facilitate user maintenance, making it particularly suitable for situations where the abutment is a fixed component.

[0079] In addition, in the above embodiments, in order to achieve rolling contact between the abutment and the dust cup cover, the rolling element is a wheel of the abutment. In this utility model, the rolling element can also be disposed on the dust cup cover, and the rolling element includes, but is not limited to, rollers and ball bearings.

[0080] Furthermore, in this invention, the cover body is not limited to opening to the angle shown in the figure. Instead, the suction force and the base station limit its opening to that angle. After leaving the station, it can be manually unlocked and opened to about 90°.

[0081] In addition, in the above embodiments, the dust cup is equipped with a secondary dust collection unit, and the closing mechanism is located on the secondary cleaning cover of the secondary dust collection unit, encroaching on the upper half of the secondary cleaning cover. In this invention, the closing mechanism can also be located in other positions on the dust cup cover, avoiding the area where the secondary cleaning cover is located, thus allowing for a larger hollow space in the secondary cleaning cover. For example, the closing mechanism can be moved to the periphery (upper, lower, left, or right) of the secondary cleaning cover, or it can be configured as a ring surrounding the secondary cleaning cover, or it can be a non-complete ring, with only upper and lower or left and right arc-shaped areas. Furthermore, the upper and lower areas can also be other shapes, such as strips, discs, or hemispherical (or smaller) spheres. After the vacuum cleaner leaves the station, it is okay if the closing mechanism is accidentally touched while vacuuming, as it is for closing the cover. The key is to ensure smooth and stable entry, exit, and closing of the cover.
