Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a dust collection base station and cleaning system. Background Technology

[0002] With the popularization of intelligent cleaning equipment, dust collection base stations are widely used as supporting devices in home and commercial settings to automatically empty the dust collection containers of cleaning devices (such as vacuum cleaners, robot vacuums, etc.).

[0003] In related technologies, the bottom of the dust collection container has an openable and closable bottom cover. When the cleaning device returns to the dust collection base station, the bottom cover of the dust collection container is opened, so that the dust collection duct in the dust collection base station is connected to the dust collection container. In this way, when the dust collection base station generates dust suction force, the dust in the dust collection container is sent to the dust storage space inside the dust collection base station through the dust collection duct. After the dust collection is completed, the cleaning device is manually removed from the dust collection base station and the bottom cover is manually closed.

[0004] However, in related technologies, manually closing the bottom cover can lead to residual dust overflowing and causing secondary pollution, resulting in a poor user experience. Utility Model Content

[0005] In view of the above problems, this application provides a dust collection base station and cleaning system that can automatically close the dust collection container without manual closing, thereby preventing the problem of residual dust overflowing from the wall and causing secondary pollution, and improving the user experience.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] The first aspect of this application provides a dust collection base station for performing dust collection operations on a cleaning device. The cleaning device has an openable and closable dust collection container. The dust collection base station includes a base station body and a cover assembly. The base station body has a dust collection air duct, which is configured to communicate with the dust collection container. The cover assembly includes a drive unit, a transmission unit, and an actuating element. The transmission unit includes a transmission element, and the drive unit is configured to apply a driving force to the transmission element.

[0008] The transmission member has a first contact surface, which is configured to abut against the actuating member as the transmission member moves, thereby driving the actuating member to move along a first direction. The extension direction of the first contact surface and the first direction have an angle. The actuating member is configured to change the opening and closing state of the dust collection container by its own movement.

[0009] In the dust collection base station provided in this application embodiment, a cover closing component is provided. The cover closing component includes a driving unit, a transmission unit, and an action member. The transmission unit includes a transmission member, and the driving unit is configured to apply a driving force to the transmission member. The transmission member has a first contact surface, which is configured to contact the action member as the transmission member moves, thereby driving the action member to move along a first direction. The extension direction of the first contact surface has an angle with the first direction. In this way, the extension direction of the first contact surface can guide the movement of the action member, thereby improving the reliability of the action member's movement path. This allows the action member to change the opening and closing state of the dust collection container through its own movement, thereby achieving the purpose of automatically closing the dust collection container through the transmission member. There is no need to manually close the dust collection container, which can avoid the problem of residual dust overflowing and causing secondary pollution when manually closing, thus improving the user experience.

[0010] In some embodiments, the driving unit has a first driving direction and a second driving direction, wherein the first driving direction and the second driving direction are opposite.

[0011] With this configuration, the drive unit applies driving forces in different driving directions to the actuator through the transmission unit, thereby changing the direction of movement of the actuator and thus changing the opening and closing state of the dust collection container.

[0012] In some embodiments, the driving unit includes a driving motor and a power transmission component. The driving motor is fixed to the base station body, and the driving shaft of the driving motor has two rotation directions. The power transmission component is connected to the driving shaft of the driving motor, and when the driving shaft rotates in different rotation directions, it drives the power transmission component to move in the first driving direction and the second driving direction, respectively.

[0013] With this configuration, the direction of motion of the transmission unit is changed by rotating the drive motor in both directions, thereby changing the direction of motion of the active component through the transmission unit.

[0014] In some embodiments, the power transmission component includes a worm gear, and the drive shaft of the drive motor has drive teeth that mesh with the worm gear.

[0015] This configuration converts the rotational motion of the drive motor into linear motion, thereby driving the transmission components to move the actuators and thus converting the motion. In addition, the worm gear transmission has a self-locking characteristic and smooth transmission, thereby improving the reliability of the actuators' movement.

[0016] In some embodiments, the drive unit applies a force to the transmission member to move the transmission member along a second direction, wherein the first direction and the extension direction of the first contact surface both have an angle with the second direction.

[0017] This configuration allows for the conversion of transmitted motion, thereby improving the reliability of the action element in changing the opening and closing state of the dust collection container.

[0018] In some embodiments, the first direction and the second direction are orthogonal to each other.

[0019] This setup improves the smoothness and stability of motion transitions, thereby enhancing the reliability of the motion.

[0020] In some embodiments, the actuating member has a release position and a closed position. When the actuating member moves to the release position, the actuating member and the dust collection container disengage. When the actuating member moves to the closed position, the actuating member drives the dust collection container to move to the closed state.

[0021] This design improves the accuracy and reliability of the actuator in changing the opening and closing state of the dust collection container.

[0022] In some embodiments, the base station body has a mounting hole extending along a first direction, the mounting hole communicating with the dust collection duct, and the actuating member movably passing through the mounting hole.

[0023] This configuration allows for limiting the position of the actuator and guiding its movement, thereby improving the accuracy of the actuator's movement path.

[0024] In some embodiments, the cover assembly further includes an elastic member, the actuating member having a first limiting portion, the elastic member being connected between the first limiting portion and the base station body, and the elastic member being configured to drive the actuating member to move away from the dust collection container by its own elastic force, so that the actuating member disengages from the dust collection container.

[0025] With this configuration, as long as the driving force applied to the actuator is released, the elastic element can drive the actuator to move in the opposite direction and thus reset through its own elastic force. The reset structure is simple and low in cost.

[0026] In some embodiments, the actuating member is a top block, and the first abutting surface is configured to abut against the end of the top block as the transmission member moves.

[0027] In some embodiments, the top block has a cavity inside, one end of the top block facing the dust collection container is an opening communicating with the cavity, the elastic member is disposed in the cavity, and the bottom wall of the cavity is formed as the first limiting portion.

[0028] This configuration allows for precise transmission of motion to the top block, thereby improving the reliability of the top block in changing the opening and closing state of the dust collection container.

[0029] In some embodiments, the top block has at least two sub-top blocks, which are spaced apart circumferentially along the top block; the mounting hole includes at least two sub-mounting holes, which are respectively configured to correspond one-to-one with the at least two sub-top blocks, with one sub-top block corresponding to one sub-mounting hole, and each sub-top block passing through the corresponding sub-mounting hole, and changing the opening and closing state of the dust collection container with the movement of the transmission member.

[0030] This configuration can further improve the reliability of the top block's movement, and at the same time, improve the reliability of the top block changing the opening and closing state of the dust collection container.

[0031] In some embodiments, the base station body further has a second limiting part, and the outer peripheral surface of the actuating member has a third limiting part; when the actuating member is disengaged from the dust collection container, the second limiting part and the third limiting part cooperate with each other.

[0032] This design limits the movement path of the actuator, preventing it from falling off and thus improving the reliability and stability of the actuator's movement path.

[0033] In some embodiments, the second limiting portion is one of a limiting groove and a limiting protrusion, and the third limiting portion is the other of a limiting groove and a limiting protrusion.

[0034] This design results in a simple, easy-to-implement, and low-cost limit structure.

[0035] In some embodiments, the end of the top block facing the first abutment surface has a guide arc surface.

[0036] This design reduces friction between the top block and the first contact surface, thereby improving the smoothness of relative movement between the top block and the first contact surface.

[0037] In some embodiments, a portion of the outer edge contour of the transmission member forms the first abutment surface.

[0038] This design simplifies the structure of the transmission components and reduces the difficulty and cost of manufacturing.

[0039] In some embodiments, the transmission member further has a second abutment surface connected to the first abutment surface, the extension direction of the second abutment surface being orthogonal to the first direction.

[0040] This design improves the reliability and stability of the transmission components in supporting the action components.

[0041] In some embodiments, the transmission member has a guide groove, a portion of the groove wall forming the first abutment surface; and another portion of the groove wall forming the second abutment surface.

[0042] With this configuration, the movement of the actuator within the guide groove can be further guided, thereby further improving the reliability and accuracy of the actuator's movement.

[0043] In some embodiments, both the first direction and the second direction form an angle with the groove opening direction of the guide groove.

[0044] This design allows the active component to extend into the guide groove and move along it.

[0045] In some embodiments, the actuating member has a guide portion that extends into the guide groove and is configured to abut against at least the first contact surface as the transmission member moves.

[0046] This design improves the reliability of the movement of the actuator within the guide groove, and the guide section can also serve as a fulcrum for the movement of the actuator, thereby enhancing the stability of the actuator.

[0047] In some embodiments, the guide portion is a guide post, and the extension direction of the guide post has an angle with the extension direction of the actuating member.

[0048] This design improves the stability and reliability of the motion of the active component, and the guide section has a simple structure that is easy to implement and has low cost.

[0049] A second aspect of this application provides a cleaning system, including a cleaning device and a dust collection base station provided in the first aspect, wherein the cleaning device has an openable and closable dust collection container.

[0050] The cleaning system provided in this application embodiment has the same beneficial effects as the dust collection base station described above, and will not be repeated here.

[0094] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0095] This application provides a cleaning system 10. Please refer to... Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, the cleaning system 10 includes a dust collection base station 100 and a cleaning device 200. The cleaning device 200 includes, but is not limited to, a handheld vacuum cleaner. Taking a handheld vacuum cleaner as an example, the cleaning device 200 has an openable and closable dust collection container 210. The dust collection container 210 is, for example, a dust cup for collecting and storing dust. The bottom of the dust collection container 210 has an openable and closable bottom cover 220. Thus, the open and closed state of the dust collection container 210 can be changed by controlling the opening and closing of the bottom cover 220.

[0096] In addition, the dust collection base station 100 includes a base station body 110, which has a dust collection air duct 111 inside. The base station body 110 also has a negative pressure device and a dust storage bag, etc. The dust storage bag is connected to the integrated air duct. When the cleaning device 200 returns to the dust collection base station 100, the bottom cover 220 of the dust collection container 210 is opened so that the dust collection container 210 is connected to the dust collection air duct 111 inside the dust collection base station 100. In this way, when the negative pressure device generates negative pressure, the dust in the dust collection container 210 can be sucked into the dust storage bag through the dust collection air duct 111. Thus, there is no need to manually clean the dust in the dust collection container 210.

[0097] For example, one end of the bottom cover 220 is pivotally connected to the dust collection container 210, and the other end of the bottom cover 220 is provided with a first buckle. The dust collection container 210 has a second buckle that matches the buckle on the bottom cover 220. In this way, when the bottom cover 220 is in the closed state, the first buckle and the second buckle are engaged. When the bottom cover 220 is in the open state, the first buckle and the second buckle are disengaged, thereby realizing the opening and closing of the dust collection container 210. The disengagement of the first buckle and the second buckle can be achieved by using a mechanical button.

[0098] For example, at least one of the first and second latches includes, but is not limited to, a resilient latch. When the bottom cover 220 is pushed to the closed state, the first and second latches can automatically engage. When disengaging, at least one of the first and second latches can be moved relative to each other by means of mechanical buttons or the like to disengage.

[0099] After the dust in the dust collection container 210 is cleaned, the dust collection container 210 is still in the open state. To close the dust collection container 210, it is usually necessary to manually remove the cleaning device 200 from the dust collection base station 100 and manually close the bottom cover 220 of the dust collection container 210. However, when the cleaning device 200 is removed from the dust collection base station 100, the dust remaining at the bottom opening of the dust collection container 210 is easy to overflow and cause secondary environmental pollution. Therefore, the embodiments of this application mainly solve the problem of how the bottom cover 220 can be automatically reset after the dust in the dust collection container 210 is cleaned.

[0100] This application provides a dust collection base station 100. By setting a cover closing component 120 on the dust collection base station 100, the bottom cover 220 of the dust collection container 210 is automatically closed by the cover closing component 120 after the dust in the dust collection container 210 is cleaned, without the need for manual closing. This avoids the problem of residual dust overflowing and causing secondary pollution when manually closing, and improves the user experience.

[0101] Based on the above content, the different structures and implementation methods of the dust collection base station 100 provided in the embodiments of this application will be described in detail below.

[0102] Example 1

[0103] Please refer to Figures 1 to 15 As shown, this application embodiment provides a dust collection base station 100, which includes a base station body 110 and a cover assembly 120. The cover assembly 120 includes a drive unit 121, a transmission unit 122, and an action member 123. The transmission unit 122 includes a transmission member 1221. The drive unit 121 is configured to apply a driving force to the transmission member 1221. The transmission member 1221 has a first contact surface 1222, which is configured to abut against the action member 123 as the transmission member 1221 moves, thereby driving the action member 123 to move along a first direction. The extension direction of the first contact surface 1222 and the first direction have an angle. The action member 123 is configured to change the opening and closing state of the dust collection container 210 by its own movement. In this way, there is no need to manually close the dust collection container 210, thereby avoiding the problem of residual dust overflowing and causing secondary pollution when manually closing, and improving the user experience.

[0104] For example, the first direction is vertical lifting and lowering. When the cleaning device 200 returns to the dust collection base station 100, the actuating member 123 is located below the dust collection container 210. When the driving unit 121 drives the actuating member 123 to move in the first direction through the transmission member 1221, the actuating member 123 rises or falls in the first direction. When the actuating member 123 rises in the first direction, it pushes against the bottom cover 220 of the dust collection container 210 and moves upward until the dust collection container 210 is closed. When the actuating member 123 falls in the first direction, it disengages from the bottom cover 220 of the dust collection container 210.

[0105] Please refer to Figures 1 to 14 As shown, the first contact surface 1222 is an inclined surface with an angle to the first direction. Thus, the height of the first inclined surface in the first direction is the movable height of the actuating member 123. Therefore, the size of the angle between the first contact surface 1222 and the first direction can be adaptively designed according to the stroke requirements of the actuating member 123 in the first direction, and no specific restrictions are imposed here.

[0106] In order to enable the actuator 123 to rise and fall along the first direction, the drive unit 121 has a first drive direction and a second drive direction in this embodiment of the application. The first drive direction and the second drive direction are opposite. In this way, the drive unit 121 applies a driving force with different drive directions to the actuator 123 through the transmission unit 122 to change the movement direction of the actuator 123, thereby changing the opening and closing state of the dust collection container 210.

[0107] Please refer to Figures 9 to 14 As shown, the drive unit 121 includes a drive motor 1211 and a power transmission component 1212. The drive motor 1211 is fixed to the base station body 110. The drive motor 1211 can be fixedly connected to the base station body 110 through a bracket 125. For example, the bracket 125 used to fix the drive motor 1211 can be fixedly connected to the base station body 110 through screws or the like. The drive shaft of the drive motor 1211 has two mutually opposite rotation directions. The power transmission component 1212 is connected to the drive shaft of the drive motor 1211. When the drive shaft rotates in different rotation directions, that is, when the drive motor 1211 rotates in both directions, it can drive the power transmission component 1212 to move in the first driving direction and the second driving direction, respectively. This causes the power transmission component 1212 to drive the transmission component 1221 to move, thereby changing the opening and closing state of the dust collection container 210.

[0108] The power transmission component 1212 can change the motion state while realizing power transmission. For example, it can change the rotational motion of the drive motor 1211 into linear motion, so that the transmission component 1221 can move in a preset direction to change the opening and closing state of the dust collection container 210.

[0109] For example, such as Figures 9 to 15 As shown, the power transmission component 1212 includes a worm gear, and the drive shaft of the drive motor 1211 has a drive tooth 1213 that meshes with the worm gear. The transmission component 1221 is connected to one end of the worm gear and is slidably connected to the first guide groove 1224 on the guide component. In this way, the output shaft of the drive motor 1211 drives the drive tooth 1213 to rotate, and the drive tooth 1213 drives the worm gear to move along the axial direction of the worm gear through gear meshing. The worm gear can drive the transmission component 1221 to rotate relative to the base station body 110, so that the transmission component 1221 passes through the clearance groove and pushes against the bottom cover 220 of the dust collection container 210 to close it. Alternatively, if the drive motor 1211 reverses, it can drive the transmission component 1221 to move in the opposite direction through the worm gear, so that the transmission component 1221 disengages from the bottom cover 220 of the dust collection container 210.

[0110] It is understandable that by setting the power transmission component 1212 as a worm gear, on the one hand, the rotational motion of the drive motor 1211 can be changed into linear motion, thereby driving the transmission component 1221 to move in a preset direction; on the other hand, the worm gear transmission has a self-locking characteristic and smooth transmission, thereby improving the reliability of the movement of the transmission component 1221.

[0111] The drive gear 1213 can be an integrally formed structure with the drive shaft of the drive motor 1211, that is, the drive shaft of the drive motor 1211 has gear teeth in the circumferential direction that match the worm; or, as... Figure 11 , Figure 12 and Figure 15 As shown, the drive gear 1213 can be a separate spur gear. In this way, the drive gear 1213 is coaxial with the drive shaft of the drive motor 1211 and is fixed relative to it, so that when the drive motor 1211 is running, it can drive the drive gear 1213 to rotate coaxially through the drive shaft.

[0112] In the embodiments of this application, please refer to Figure 9 and Figure 10 As shown, the drive unit 121 applies a force to the transmission member 1221, causing the transmission member 1221 to move along the second direction. Both the first direction and the extension direction of the first contact surface 1222 form an angle with the second direction. This allows for the conversion of transmitted motion, thereby improving the reliability of the actuator 123 in changing the opening and closing state of the dust collection container 210. For example, the first and second directions are orthogonal to each other. The second direction is, for example, aligned with the axial direction of the worm gear. When the worm gear is horizontally placed, the first direction is vertical, meaning the actuator 123 can move vertically up and down, thereby improving the smoothness and stability of motion conversion, and ultimately enhancing the reliability of the motion.

[0113] For example, such as Figure 9 and Figure 10 In this configuration, the second direction is consistent with the axial extension direction of the worm. The transmission component 1221 is fixedly connected to the end of the worm. Thus, when the drive motor 1211 drives the worm to move through the drive teeth 1213, the worm drives the transmission component 1221 to move along the axial direction of the worm. When the transmission component 1221 moves along the axial direction of the worm, the first abutting surface 1222 on the transmission component 1221 abuts against the actuating component 123, so that as the transmission component 1221 moves along the second direction, the actuating component 123 moves up and down along the first direction, thereby changing the opening and closing state of the dust collection container 210 through the actuating component 123.

[0114] In addition, the actuator 123 has a release position and a closed position. When the actuator 123 moves to the release position, the actuator 123 and the dust collection container 210 are no longer in contact. When the actuator 123 moves to the closed position, the actuator 123 drives the dust collection container 210 to move to the closed state. In this way, the accuracy and reliability of the actuator 123 changing the opening and closing state of the dust collection container 210 are further improved.

[0115] For example, Figure 6 , Figure 8 as well as Figure 14 In the middle, the actuators 123 are all in the closed position, at which time the dust collection container 210 is in the closed state; while Figure 2 , Figure 4 and Figure 13 In this state, the actuators 123 are both in the released position. At this time, the dust collection container 210 can be in an open state or a closed state, but the actuators 123 are in a state of disengagement from the bottom cover 220 of the dust collection container 210.

[0116] Please refer to Figure 12 As shown, the base station body 110 has a mounting hole 112 extending along a first direction. The mounting hole 112 is connected to the dust collection duct 111. The actuating member 123 is movably inserted into the mounting hole 112. In this way, when the transmission member 1221 pushes the actuating member 123 to move along the first direction, the mounting hole 112 can position and limit the position of the actuating member 123 in the first direction and guide the movement of the actuating member 123, thereby improving the accuracy of the movement path of the actuating member 123. This can avoid the problem of low reliability caused by the actuating member 123 shifting in the first direction, which would change the opening and closing state of the dust collection container 210.

[0117] When the transmission component 1221 releases the driving force on the actuating component 123, in order for the actuating component 123 to automatically reset, that is, to automatically reset from the closed position to the released position, please refer to... Figures 9 to 14 As shown, the cover assembly 120 also includes an elastic member 124. The actuating member 123 has a first limiting part 1231. The elastic member 124 is connected between the first limiting part 1231 and the base station body 110. The elastic member 124 is configured to drive the actuating member 123 to move away from the dust collection container 210 by its own elastic force, so that the actuating member 123 is disengaged from the dust collection container 210. In this way, as long as the driving force applied to the actuating member 123 is released, the elastic member 124 can drive the actuating member 123 to move in the opposite direction and reset by its own elastic force. The reset structure is simple and low cost.

[0118] For example, the elastic element 124 includes, but is not limited to, a spring. As long as it can drive the actuating element 123 from the closed position to the released position by its own elastic force when the actuating element 123 is not under force, no specific limitation is made here.

[0119] In some embodiments, the actuating member 123 is a top block or a top rod. For example, the actuating member 123 can be a block or rod structure with an arbitrary shape such as a circle, ellipse, or polygon. The first abutting surface 1222 is configured to abut against the end of the top block as the transmission member 1221 moves. In this way, the transmission member 1221 is located below the actuating member 123. When the transmission member 1221 moves toward the actuating member 123 in the second direction, the first abutting surface 1222 on the transmission member 1221 can push the actuating member 123 to move in the first direction as long as it contacts the end of the actuating member 123.

[0120] To further improve the structural compactness, please refer to... Figures 10 to 12 As shown, the top block has a cavity 1232 inside. The end of the top block facing the dust collection container 210 is an opening communicating with the cavity 1232. An elastic member 124 is disposed in the cavity 1232. The bottom wall of the cavity 1232 is formed as a first limiting part 1231. Thus, when the top block is in the closed position, the elastic member 124 is limited between the bottom wall of the cavity 1232 and the structure of the base station body 110 part corresponding to the mounting hole 112. At this time, the elastic member 124 is in a compressed state. When the driving force on the top block is released, the elastic member 124 is compressed. The elastic element 124 drives the top block to move from the closed position to the released position through its own elastic force. In addition, by setting the elastic element 124 in the cavity 1232, the structure of the closing assembly 120 can be improved and the space utilization can be increased while realizing the automatic reset of the top block. Furthermore, by setting the elastic element 124 in the cavity 1232, the elastic element 124 can accurately transmit the motion to the top block when driving the top block to reset, thereby improving the reliability of the top block changing the opening and closing state of the dust collection container 210.

[0121] In order to confine the elastic element 124 between the cavity 1232 of the top block and the structure of the base station body 110 corresponding to the mounting hole 112, in this embodiment of the application, as follows: Figure 11 and Figure 12 As shown, the top block has at least two sub-top blocks 1233, which are spaced apart circumferentially along the top block. The mounting hole 112 includes at least two sub-mounting holes 112, which are respectively configured to correspond one-to-one with the at least two sub-top blocks 1233. One sub-top block 1233 corresponds to one sub-mounting hole 112. Each sub-top block 1233 passes through the corresponding sub-mounting hole 112 and changes the opening and closing state of the dust collection container 210 with the movement of the transmission member 1221. In this way, while the mounting hole 112 limits the top block, it can improve the positional reliability of the elastic member 124, further improve the reliability of the top block movement, and improve the reliability of the top block changing the opening and closing state of the dust collection container 210.

[0122] To further improve the accuracy of the movement stroke of the actuating member 123 in the first direction, enabling the actuating member 123 to precisely switch between the closed position and the released position, in this embodiment of the application, such as Figures 11 to 14 As shown, the base station body 110 also has a second limiting part 113, and the outer peripheral surface of the action member 123 has a third limiting part 1234. When the action member 123 is disengaged from the dust collection container 210, the second limiting part 113 and the third limiting part 1234 cooperate with each other to limit the movement path of the action member 123, so as to prevent the action member 123 from falling off the base station body 110, thereby improving the reliability and stability of the movement path of the action member 123.

[0123] For example, the second limiting portion 113 is one of a limiting groove and a limiting protrusion, and the third limiting portion 1234 is the other of a limiting groove and a limiting protrusion. For example, in Figures 11 to 14 In this design, the second limiting part 113 is a limiting groove, and the third limiting part 1234 is a limiting protrusion. In this way, the limiting structure is simple, easy to implement, and low in cost.

[0124] The actuator 123 has multiple limiting protrusions, which are spaced apart along the periphery of the actuator 123. Correspondingly, each limiting protrusion has a limiting groove that extends along a first direction. When the actuator 123 moves along the first direction, the limiting protrusion moves along the first direction in the limiting groove. When the actuator 123 moves to the closed position, the limiting protrusion abuts against the top wall of the limiting groove. When the actuator 123 moves to the released position, the limiting protrusion abuts against the bottom wall of the limiting groove.

[0125] Additionally, please refer to Figure 11 and Figure 12 As shown, the end of the top block facing the first abutment surface 1222 has a guide arc surface 1235, which can reduce the friction between the top block and the first abutment surface 1222, thereby improving the smoothness of the relative movement between the top block and the first abutment surface 1222.

[0126] In some embodiments, such as Figures 1 to 14 As shown, a portion of the outer edge contour of the transmission member 1221 forms a first abutting surface 1222, that is, one side of the transmission member 1221 is formed as an inclined surface with an angle to the first direction. In this way, the inclined surface is formed as the first abutting surface 1222, thereby simplifying the structure of the transmission member 1221 and reducing the manufacturing difficulty and cost.

[0127] In some embodiments, please continue to refer to Figures 1 to 14As shown, the transmission member 1221 also has a second abutment surface 1223 connected to the first abutment surface 1222. The extension direction of the second abutment surface 1223 is orthogonal to the first direction. For example, when the first direction is vertical, the second abutment surface 1223 extends in the horizontal direction, and the second abutment surface 1223 is located on the side close to the dust collection container 210. Figures 12 to 14 As shown, the second abutment surface 1223 is located above the first abutment surface 1222. The second abutment surface 1223 is a flat plane extending in the horizontal direction. When the abutment 123 moves to the closed position, the bottom end of the abutment 123 abuts against the second abutment surface 1223. In this way, the support stability of the abutment 123 by the second abutment surface 1223 on the abutment 123 is improved when the abutment 123 is in the closed position.

[0128] Among them, such as Figures 12 to 14 As shown, the first contact surface 1222 and the second contact surface 1223 are both formed by part of the outer edge contour of the transmission component 1221, which is simple in structure and reduces structural cost.

[0129] In a specific implementation of this application embodiment, when the dust collection container 210 returns to the base station body 110 and the bottom cover 220 is opened for dust collection, such as Figures 1 to 4 , Figure 13 As shown, the bottom cover 220 is currently in the open state, and the actuating element 123 in the closing assembly 120 is in a state of disengagement from the bottom cover 220 on the dust collection container 210, that is, the actuating element 123 is in the released position. Thus, the dust collection container 210 is connected to the dust collection duct 111 in the base station body 110. The negative pressure device inside the base station body 110 generates negative pressure, allowing the dust in the dust collection container 210 to be collected through the dust collection duct 111 into a dust storage space such as a dust storage bag inside the base station body 110. After the dust in the dust collection container 210 is cleaned, the drive motor 1211 in the drive unit 121 rotates, for example, forward, causing the drive shaft of the drive motor 1211 to drive the drive gear 1213 to rotate, driving... The gear 1213 drives the meshing worm to move along the worm's axial direction. The worm drives the transmission component 1221 to move linearly along the worm's axial direction. At this time, the transmission component 1221 moves towards the actuating component 123. When the first abutting surface 1222 on the transmission component 1221 abuts against the end of the actuating component 123, as the transmission component 1221 continues to move, the first abutting surface 1222 pushes the actuating component 123 upward in the first direction. The actuating component 123 pushes the bottom cover 220 of the dust collection container 210 upward until the end of the actuating component 123 abuts against the second abutting surface 1223. At this time, the actuating component 123 pushes the bottom cover 220 into a closed state, and the actuating component 123 is in the closed position, realizing the automatic closing of the bottom cover 220 (e.g., Figures 5 to 8 , Figure 14(As shown in the diagram); when the bottom cover 220 is closed, the drive motor 1211 reverses to drive the worm gear to move in the opposite direction along the worm's axis via the drive gear 1213, so that the worm gear drives the transmission component 1221 to move away from the action component 123. At this time, the action component 123 is driven to move downward under the elastic force of the elastic component 124 until the elastic component 124 is in a free state and the action component 123 is in the released position. There is no need to manually close the dust collection container 210, which can avoid the problem of residual dust overflowing and causing secondary pollution when manually closing, thus improving the user experience.

[0130] Example 2

[0131] This application only describes the differences from the above embodiment one; the same structures will not be described again here.

[0132] Please refer to Figures 16 to 29 As shown, the difference between the dust collection base station 100 provided in this application embodiment and the one in the above embodiment is that the structure of the transmission member 1221 and the structure of the actuating member 123 are different. Specifically, the first abutting surface 1222 and the second abutting surface 1223 on the transmission member 1221 are not formed by part of the outer edge contour of the transmission member 1221. Instead, the transmission member 1221 has a guide groove 1224, and part of the groove wall of the guide groove 1224 forms the first abutting surface 1222. The other part of the groove wall of the guide groove 1224 forms the second abutting surface 1223. For example, the groove wall of the guide groove 1224 that has an inclined angle with the first direction is the first abutting surface 1222, and the groove wall that is connected to and above the first abutting surface 1222 is formed as the second abutting surface 1223. In this way, the movement of the actuating member 123 in the guide groove 1224 can be further guided, thereby further improving the reliability and accuracy of the movement of the actuating member 123.

[0133] Please refer to Figures 24 to 27 As shown, both the first and second directions form an angle with the groove direction of the guide groove 1224. For example, the groove of the guide groove 1224 is located on the side of the transmission member 1221. Figure 24 As shown, the groove opening of the guide groove 1224 is along a third direction, which is perpendicular or approximately perpendicular to the first direction and the second direction, respectively. In this way, the actuating member 123 enters the guide groove 1224 from the groove opening and moves along the contour of the guide groove 1224 under the action of the driving force.

[0134] Please continue to refer to Figures 24 to 27As shown, the actuating member 123 has a guide portion 1236 that extends into the guide groove 1224 and is configured to abut against at least the first contact surface 1222 as the transmission member 1221 moves. This improves the reliability of the movement of the actuating member 123 within the guide groove 1224. The guide portion 1236 can also serve as a fulcrum for the movement of the actuating member 123, thereby improving the stability of the actuating member 123.

[0135] For example, the guide portion 1236 is a guide post, and there is an angle between the extension direction of the guide post and the extension direction of the actuating member 123. In this way, the stability and reliability of the movement of the actuating member 123 are improved, and the structure of the guide portion 1236 is simple, easy to implement, and low in cost.

[0136] When the actuating member 123 moves to the closed position, the guide post abuts against the second abutting surface 1223. When the actuating member 123 moves to the released position, the guide post abuts against the first abutting surface 1222.

[0137] In addition, the worm gear has a rectangular connecting plate on the side near the transmission component 1221. The connection position between the transmission component 1221 and the connecting plate is offset from the axis of the worm gear in the third direction. This is to adapt to the position of the action component 123, thereby improving the flexible layout of the structure and meeting different structural position requirements.

[0138] In a specific implementation of this application embodiment, when the dust collection container 210 returns to the base station body 110 and the bottom cover 220 is opened for dust collection, such as Figures 16 to 19 , Figure 28As shown, the bottom cover 220 is currently in the open state, and the actuating element 123 in the closing assembly 120 is in a state of disengagement from the bottom cover 220 on the dust collection container 210, that is, the actuating element 123 is in the released position. In this way, the dust collection container 210 is connected to the dust collection duct 111 in the base station body 110, and the negative pressure device in the base station body 110 generates negative pressure so that the dust in the dust collection container 210 can be collected through the dust collection duct 111 into the dust storage space such as the dust storage bag in the base station body 110. After the dust in the dust collection container 210 is cleaned, the drive motor 1211 in the drive unit 121 rotates, for example, in the forward direction, so that the drive shaft of the drive motor 1211 drives the drive gear 1213 to rotate, and the drive gear 1213 drives it to mesh. The worm moves along its axial direction, driving the transmission component 1221 to move linearly along the axial direction. The guide portion 1236 on the actuating component 123 is located within the guide groove 1224 of the transmission component 1221. When the transmission component 1221 moves in the second direction, the guide portion 1236 moves along the guide groove 1224. The first contact surface 1222 in the guide groove 1224 pushes the actuating component 123 upward in the first direction as the transmission component 1221 moves. The actuating component 123 pushes the bottom cover 220 of the dust collection container 210 upward until the end of the actuating component 123 abuts against the second contact surface 1223. At this time, the actuating component 123 is in the closed state, and the actuating component 123 is in the closed position, realizing the automatic closing of the bottom cover 220 (e.g., Figures 20 to 23 , Figure 29 (As shown in the diagram); when the bottom cover 220 is closed, the drive motor 1211 reverses to drive the worm gear to move in the opposite direction along the worm's axis via the drive gear 1213, so that the worm gear drives the transmission component 1221 to move in the opposite direction. The actuating component 123 releases its contact with the second contact surface 1223. At this time, the actuating component 123 is driven to move downward along the first contact surface 1222 under the elastic force of the elastic component 124 until the elastic component 124 is in a free state and the actuating component 123 is in a released state. There is no need to manually close the dust collection container 210, which can avoid the problem of residual dust overflowing and causing secondary pollution when manually closing, thus improving the user experience.

[0139] In summary, the dust collection base station provided in this application embodiment includes a cover-closing component. The cover-closing component includes a driving unit, a transmission unit, and an action member. The transmission unit includes a transmission member, and the driving unit is configured to apply a driving force to the transmission member. The transmission member has a first contact surface, which is configured to contact the action member as the transmission member moves, thereby driving the action member to move along a first direction. The extension direction of the first contact surface has an angle with the first direction. In this way, the extension direction of the first contact surface can guide the movement of the action member, thereby improving the reliability of the action member's movement path. This allows the action member to change the opening and closing state of the dust collection container through its own movement, thereby achieving the purpose of automatically closing the dust collection container through the transmission member. This eliminates the need for manual closing of the dust collection container, thus avoiding the problem of residual dust overflowing and causing secondary pollution when manually closing the container, and improving the user experience.
