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.

[0008] The cover closing 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 to cause the transmission element to rotate about a rotation axis.

[0009] The actuating element and the transmission element are connected in cooperation, and the actuating element moves along a preset direction under the drive of the transmission element to change the opening and closing state of the dust collection container.

[0010] In the dust collection base station provided in this application embodiment, a cover-closing component is set up. The cover-closing component includes a driving unit, a transmission unit, and an action member. The transmission unit includes a transmission member. The driving unit is configured to apply a driving force to the transmission member so that the transmission member rotates around a rotation axis. The action member is connected to the transmission member and moves along a preset direction under the drive of the transmission member. In this way, the accuracy and reliability of the movement path of the action member can be improved, so that the action member can 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, and improve the user experience.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] In some embodiments, the power transmission component is a worm gear, which is coaxially connected to the drive shaft of the drive motor.

[0016] This configuration allows the motion of the drive motor to be transmitted to the transmission unit via a worm gear. In addition, the worm gear transmission has a self-locking characteristic and provides smooth transmission, thereby improving the reliability of the movement of the active components.

[0017] In some embodiments, there is an angle between the preset direction and the axis of the rotation axis.

[0018] This configuration allows for motion conversion, thereby improving the accuracy and reliability of the motion path of the active component.

[0019] In some embodiments, the transmission element includes a gear configured to transmit power from the drive unit to the transmission element to cause the transmission element to rotate about the rotation axis.

[0020] This design achieves motion transmission while maintaining a simple and low-cost transmission component structure.

[0021] In some embodiments, the transmission element includes at least two gears that mesh sequentially between the drive unit and the actuator.

[0022] This configuration allows for changes in the speed and direction of motion transmitted to the actuators to adapt to motion requirements.

[0023] In some embodiments, the at least two gears constitute at least one transmission gear set; each transmission gear set includes a first gear and a second gear, the first gear and the second gear rotating synchronously about the same axis, and the module of the first gear and the module of the second gear are different.

[0024] This configuration allows for different transmission ratios, thereby meeting the motion requirements of different speeds and torques.

[0025] In some embodiments, the actuating element includes a rack, and the rack meshes with the gear.

[0026] With this configuration, the transmission components can accurately transmit motion to the actuators, thereby improving the accuracy and reliability of the actuators' motion.

[0027] In some embodiments, the transmission member has an abutting portion that abuts against the actuating member, and the distance between the abutting portion and the rotation axis is different in the preset direction when the transmission member rotates about the rotation axis to different angles.

[0028] With this configuration, the relative rotation of the transmission component and the actuator can drive the movement of the actuator, resulting in a simple motion method and low implementation cost.

[0029] In some embodiments, the transmission element includes a cam, the rim of which forms the abutment portion, so as to drive the actuating element to move to different positions when the cam rotates to different angles.

[0030] This configuration utilizes the rim characteristics of the cam to drive the actuator to move in a preset direction via a transmission component. It is simple in structure, easy to implement, and low in cost.

[0031] In some embodiments, the abutment portion is eccentrically disposed relative to the rotation axis of the transmission member.

[0032] This configuration increases the stroke of the actuator, meets its motion requirements, and is simple and cost-effective.

[0033] In some embodiments, the dust collection base station further includes a guide member defining a guide groove extending along the preset direction, and the actuating member moving along the guide groove.

[0034] This configuration can further improve the accuracy of the movement path of the actuator, thereby enhancing the reliability and stability of the actuator in changing the opening and closing state of the dust collection container.

[0035] In some embodiments, the actuating member has a guide post, the guide member has a guide groove extending in a preset direction, and the guide post passes through the guide groove and moves along the guide groove.

[0036] With this configuration, the guide column can further guide and support the movement of the active component, thereby improving the accuracy of the movement path and the stability of the movement.

[0037] In some embodiments, the actuating member has a positioning groove, and the abutting portion extends into the positioning groove and abuts against the groove wall.

[0038] This design improves the reliability between the transmission components and the actuators, thereby enhancing the reliability of the transmission components in driving the actuators.

[0039] In some embodiments, the preset direction and the axis of the rotation axis are parallel or coincident with each other.

[0040] This configuration simplifies the structure of the drive unit and actuators, reducing costs.

[0041] In some embodiments, the transmission member has a first threaded structure, the actuating member has a second threaded structure that cooperates with the first threaded structure, and when the transmission member rotates about the rotation axis, the first threaded structure compresses the second threaded structure to drive the actuating member to move along the preset direction.

[0042] This design improves the compactness of the structure and increases space utilization.

[0043] In some embodiments, the first thread structure is an internal threaded hole, and the second thread structure is an external thread that can be screwed into the internal threaded hole.

[0044] This setup is simple, easy to implement, and low in cost.

[0045] In some embodiments, the dust collection base station further includes a limiting member, which is fixed to the actuating member and is slidably connected to the base station body along the preset direction.

[0046] This setting limits the travel distance of the actuator, thereby improving the reliability and accuracy of the actuator's movement path.

[0047] In some embodiments, the limiting member has a first guide portion extending along the preset direction, and the base station body has a second guide portion extending along the preset direction, the first guide portion and the second guide portion cooperating with each other.

[0048] This design further improves the accuracy of the movement path between the limiting component and the base station body, thereby enhancing the reliability of the movement path of the active component.

[0049] In some embodiments, the first guide portion is a guide protrusion protruding from the outer wall of the limiting member, and the second guide portion is a guide groove that matches the guide protrusion.

[0050] This setup is simple, easy to implement, and low in cost.

[0051] In some embodiments, the transmission member is further provided with meshing teeth configured to mesh with the drive unit to rotate about the rotation axis under the drive of the drive unit.

[0052] This configuration allows the motion of the drive unit to be transmitted to the transmission components via meshing teeth, thus improving the accuracy of motion transmission.

[0053] In some embodiments, the transmission member is a rotating body, and the transmission member has a rotating surface extending circumferentially, with the meshing teeth distributed on the rotating surface.

[0054] This design improves structural compactness and simplifies the structure, thus reducing costs.

[0055] In some embodiments, the transmission member has a rotary through hole that extends through the transmission member along its length. The transmission member is mounted on the base station body by fasteners passing through the rotary through hole, and the transmission member is rotatable about its own axis.

[0056] This configuration limits and positions the transmission components and the base station body, thereby improving the reliability and stability of the transmission component's position, and thus enhancing the reliability and accuracy of the motion transmission.

[0057] 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.

[0058] 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.

[0120] 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.

[0121] This application provides a cleaning system 10. Please refer to... Figure 1 and Figure 2 As 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] Example 1

[0129] Please refer to Figures 1 to 15 As shown in the figure, 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 so that the transmission member 1221 rotates around a rotation axis. The action member 123 is connected to the transmission member 1221 and moves along a preset direction under the drive of the transmission member 1221 to change the opening and closing state of the dust collection container 210. This achieves the purpose of automatically closing the dust collection container 210 through the transmission member 1221, eliminating the need for manual closing of the dust collection container 210. This avoids the problem of residual dust overflowing and causing secondary pollution when manually closing, thus improving the user experience.

[0130] For example, such as Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figures 12 to 15 As shown, the actuator 123 moves vertically under the drive of the transmission member 1221 to switch between the closed position and the released position. When the actuator 123 rises, it directly contacts the bottom cover 220 of the dust collection container 210 and pushes against the bottom cover 220 of the dust collection container 210 as the actuator 123 rises, so that the bottom cover 220 moves to the closed position, at which time the actuator 123 is in the closed position; when the actuator 123 falls, it disengages from the bottom cover 220 and the actuator 123 is in the released position.

[0131] like Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figures 12 to 15 As shown, in order to realize the vertical upward and downward movement of the actuator 123, in this embodiment of the application, the drive unit 121 has a first drive direction and a second drive direction, which are opposite to each other. In this way, the drive unit 121 applies a driving force with different driving 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.

[0132] Please refer to Figures 7 to 10 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, and the drive shaft of the drive motor 1211 has two 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.

[0133] For example, such as Figures 9 to 15 As shown, the power transmission component 1212 includes a worm gear, which is coaxially and fixedly connected to the drive shaft of the drive motor 1211, so that the drive shaft of the drive motor 1211 drives the worm gear to rotate. The worm gear then transmits the motion to the action component 123 through the transmission component 1221, which is, for example, a gear. In this way, the worm gear meshes with the gear, and the action component 123 is, for example, a rack meshing with the gear. The drive motor 1211 drives the worm gear to rotate around its own axis, and the worm gear drives the gear to rotate around the rotation axis of the gear. The gear then drives the rack to move in a preset direction (for example, vertically), thereby changing the opening and closing state of the dust collection container 210.

[0134] It is understandable that by setting the power transmission component 1212 as a worm gear and the transmission component 1221 as a gear, on the one hand, the accuracy of motion transmission can be improved; 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.

[0135] The worm can be integrally formed with the drive shaft of the drive motor 1211, or the worm can be set separately. In this way, the worm and the drive shaft of the drive motor 1211 are coaxial and relatively fixed through a coupling, so that when the drive motor 1211 is running, it can drive the worm to rotate coaxially through the drive shaft.

[0136] like Figure 9 and Figure 10 As shown, the direction of motion of the actuator 123 (i.e., the preset direction) is at an angle to the axis of rotation of the transmission member 1221. For example, the preset direction and the axis of rotation are intersected to convert the rotational motion of the drive unit 121 into the linear motion of the actuator 123 through the transmission member 1221, thereby satisfying the motion requirements of the actuator 123.

[0137] It should be noted that when the transmission component 1221 is a gear, there can be one gear or at least two gears. When there are at least two gears, the at least two gears mesh sequentially between the drive unit 121 and the actuator 123. The movement speed and direction of the actuator 123 can be changed by the at least two gears.

[0138] Please refer to Figures 7 to 10 As shown, at least two gears constitute at least one transmission gear set. Each transmission gear set includes a first gear 1221a and a second gear 1221b. The first gear 1221a and the second gear 1221b rotate synchronously around the same axis. The module of the first gear 1221a and the module of the second gear 1221b are different, which can realize different transmission ratios, thereby meeting the motion requirements of different speeds and torques.

[0139] The transmission gear set can be one or more, and its number is determined by the movement speed and direction of the actuators 123. For example, such as... Figure 9 , Figure 13 and Figure 14 As shown, the transmission gear set is one, while... Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, there are three transmission gear sets. Of course, the transmission gear sets can also be set to four, five, etc., according to other requirements. The specific settings should be adapted according to actual needs, and no specific restrictions are made here.

[0140] The gear can be a spur gear, helical gear, or herringbone gear, as long as it can satisfy the transmission of motion; there are no restrictions here.

[0141] like Figures 7 to 10 As shown, the actuator 123 is a rack extending in a preset direction (e.g., vertical), and the rack meshes with a gear. In this way, the gear can accurately transmit motion to the rack, thereby improving the accuracy and reliability of the rack's motion.

[0142] Please refer to Figures 4 to 11 As shown, the dust collection base station 100 also includes an upper housing 127 and a lower housing 128 for fixing the cover assembly 120. The upper housing 127 and the lower housing 128 are fastened to each other to jointly enclose a receiving cavity for accommodating the cover assembly 120. At least one of the upper housing 127 and the lower housing 128 is provided with a through hole through which the actuating member 123 can pass. In addition, at least one of the upper housing 127 and the lower housing 128 has a guide structure extending in a preset direction (e.g., vertical). When the driving unit 121 drives the actuating member 123 to move through the transmission unit 122, the guide structure guides the actuating member 123 so that the actuating member 123 moves in a preset direction (e.g., vertical) to improve the accuracy of the path of the actuating member 123, thereby improving the reliability of the actuating member 123 in changing the opening and closing state of the dust collection container 210.

[0143] In the specific implementation of the dust collection base station 100 provided in 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 processing, such as Figure 1 and Figure 2 , Figure 12 As shown, the bottom cover 220 is in the open state at this time, and the actuating element 123 in the closing assembly 120 is in a state of discontinuation from the bottom cover 220 on the dust collection container 210, that is, the actuating element 123 is in the release 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 collection container 210 is cleaned, the drive motor 1211 in the drive unit 121 rotates clockwise, causing the drive shaft of the drive motor 1211 to drive the worm gear to rotate. The worm gear drives the gear meshing with it to rotate around the gear's rotation axis. The gear then drives the rack to move, causing the rack to move linearly in a preset direction, so that the rack moves toward the closed position and pushes the bottom cover 220 of the dust collection container 210 upward until the rack is in the closed position, thus realizing the automatic closing of the bottom cover 220 (e.g.). Figures 3 to 4 , Figure 13(As shown in the diagram); when the bottom cover 220 is closed, the drive motor 1211 reverses to drive the gear to reverse around the axis of rotation via the worm gear. The gear then drives the rack to move in the opposite direction, so that the rack moves in the opposite direction until the action 123 is in the release 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 closed, thus improving the user experience.

[0144] Example 2

[0145] This application only describes the differences from the above embodiment one; the same structures will not be described again here.

[0146] The difference between the dust collection base station 100 provided in this embodiment and the one in Embodiment 1 above is that the structures of the transmission unit 122 and the actuating element 123 are different from those in Embodiment 1. For details, please refer to... Figures 16 to 29 As shown, the preset direction and the axis of rotation are parallel or coincident with each other, which can simplify the structure of the drive unit 121 and the actuator 123 and reduce costs.

[0147] In some embodiments, such as Figure 24 and Figure 25 As shown, the transmission component 1221 has a first threaded structure 12214, and the actuating component 123 has a second threaded structure (1232) that cooperates with the first threaded structure 12214. When the transmission component 1221 rotates around the rotation axis, the first threaded structure 12214 presses the second threaded structure (1232) to drive the actuating component 123 to move in a preset direction. For example, the first threaded structure 12214 is an internal threaded hole, and the second threaded structure (1232) is an external thread that can be screwed into the internal threaded hole. The actuating component 123 passes through the internal threaded hole of the transmission component 1221 and is threadedly engaged with the internal threaded hole. In this way, the compactness of the structure is improved, the space utilization rate is increased, the overall volume of the cover assembly 120 is reduced, and the structure is simple, easy to implement, and low in cost.

[0148] Please refer to Figure 17 , Figure 19 , Figure 21 , Figures 23 to 25 , Figure 28 and Figure 29 As shown, the dust collection base station 100 also includes a limiting member 125, which is fixed to the actuating member 123. For example, the limiting member 125 is disposed at the end of the actuating member 123 facing the dust collection container 210, and the limiting member 125 is slidably connected to the base station body 110 along a preset direction. In this way, the movement stroke of the actuating member 123 can be limited, so that the actuating member 123 can switch between the closed position and the released position, thereby improving the reliability and accuracy of the movement path of the actuating member 123.

[0149] Additionally, please refer to Figure 24 and Figure 25 As shown, the limiting member 125 has a first guide portion 1251 extending in a preset direction, and the base station body 110 has a second guide portion 112 extending in a preset direction. The first guide portion 1251 and the second guide portion 112 cooperate with each other, which can further improve the accuracy of the movement path between the limiting member 125 and the base station body 110, thereby improving the reliability of the movement path of the action member 123.

[0150] For example, the first guide portion 1251 is a guide protrusion protruding from the outer wall of the limiting member 125, and the second guide portion 112 is a guide groove 1241 that matches the guide protrusion. The guide groove 1241 extends along a preset direction (e.g., vertical). In this way, when the actuating member 123 moves along the preset direction, the first guide portion 1251 and the second guide portion 112 slide relative to each other to guide and limit the movement of the actuating member 123. The structure of the guide portion is simple, easy to implement, and low in cost.

[0151] like Figure 24 and Figure 25 As shown, the limiting member 125 is a limiting cover. The peripheral wall of the limiting cover has at least two guide protrusions spaced apart. The base station body 110 has a plurality of guide grooves 1241 extending along a preset direction. One guide protrusion corresponds to one guide groove 1241. The guide protrusion slides along the guide groove 1241.

[0152] Among them, such as Figure 26 As shown, the end of the limiting member 125 facing the actuating member 123 has a limiting post 1252, and the end of the actuating member 123 has a limiting groove 1233 at the position corresponding to the limiting post 1252 (e.g., Figure 24 and Figure 25 As shown, the limiting post 1252 is engaged in the limiting groove 1233 to limit and fix the action member 123 and the limiting member 125, thereby restricting the circumferential movement of the action member 123. This allows the transmission member 1221 to convert the rotational motion into linear motion when rotating around its own axis, thus causing the action member 123 to move along a preset direction.

[0153] For example, the limiting post 1252 has a rectangular or polygonal cross-sectional profile, and correspondingly, the profile shape of the limiting groove 1233 matches the profile shape of the limiting post 1252.

[0154] Please continue to refer to Figure 24 and Figure 25As shown, the transmission component 1221 is also provided with meshing teeth 12213, which are configured to mesh with the drive unit 121 to rotate around the rotation axis under the drive of the drive unit 121, so as to transmit the motion of the drive unit 121 to the transmission component 1221 through the meshing teeth 12213, thereby improving the accuracy of motion transmission.

[0155] For example, the transmission component 1221 is a rotating body and has a rotating surface extending along its own circumference. The meshing teeth 12213 are distributed on the rotating surface. The worm meshes with the meshing teeth 12213. When the drive motor 1211 drives the worm to rotate, the worm drives the meshing teeth 12213 to drive the transmission component 1221 to rotate around its own axis. The internal threaded hole in the transmission component 1221 and the external thread on the actuating component 123 move in a relative spiral motion, thereby realizing the movement of the actuating component 123 in a preset direction, which improves the structural compactness and has a simple structure, and can reduce costs.

[0156] In some embodiments, the transmission member 1221 has a rotary through hole that extends through the transmission member 1221 along its length. The transmission member 1221 is mounted on the base station body 110 by fasteners 126 passing through the rotary through hole, and the transmission member 1221 can rotate around its own axis. In this way, the fasteners 126 limit and position the transmission member 1221 and the base station body 110, thereby improving the reliability and stability of the position of the transmission member 1221, and further improving the reliability and accuracy of the motion transmission.

[0157] In a specific implementation of the dust collection base station 100 provided in 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 Figure 16 and Figure 17 , 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. This causes the drive shaft of the drive motor 1211 to drive the worm gear to rotate. The worm gear engages with the meshing teeth 12213 on the transmission component 1221, driving the transmission component 1221 to rotate around its own rotation axis. The internal threaded hole inside the transmission component 1221 engages with the external thread on the actuating component 123, causing the actuating component 123 (e.g., a screw) to move linearly in a preset direction. This causes the actuating component 123 to drive the limiting component 125 towards the closed position, and through the limiting component 125, push the bottom cover 220 of the dust collection container 210 upward until the actuating component 123 is in the closed position, thus achieving the automatic closing of the bottom cover 220 (e.g., ...). Figures 18 to 19 , Figure 29 (As shown in the diagram); when the bottom cover 220 is closed, the drive motor 1211 reverses, so as to drive the transmission component 1221 to reverse around the axis of rotation via the worm gear. The transmission component 1221 then drives the action component 123 to move in the opposite direction, so that the action component 123 moves in the opposite direction (for example, vertically downward) until the action component 123 is in the release 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 closed, and improve the user experience.

[0158] Example 3

[0159] This application only describes the differences from the above embodiment one; the same structures will not be described again here.

[0160] like Figures 30 to 42 As shown in the figure, the dust collection base station 100 provided in this application embodiment is based on the first embodiment. An abutment part 12211 is provided on the transmission member 1221 (e.g., gear). The abutment part 12211 abuts against the action member 123. When the transmission member 1221 rotates around the rotation axis to different angles, the distance between the abutment part 12211 and the rotation axis in the preset direction is different. In this way, the relative rotation of the transmission member 1221 and the action member 123 can drive the movement of the action member 123. The movement mode is simple and the implementation cost is low.

[0161] For example, such as Figure 31 , Figures 33 to 35 , Figure 38 , Figure 40 and Figure 41 As shown, the transmission component 1221 includes a cam, and the rim of the cam forms an abutment portion 12211 so that when the cam rotates to different angles, it drives the actuator 123 to move to different positions. Through the rim feature of the cam, the actuator 123 can move, for example, vertically. The structure is simple, easy to implement, and low in cost.

[0162] like Figure 31 , Figures 33 to 35 , Figure 38 , Figure 40 and Figure 41 As shown, the abutment portion 12211 is eccentrically arranged relative to the rotation axis of the transmission member 1221. This increases the stroke of the action member 123, meets the motion requirements of the action member 123, and is simple to implement and low in cost.

[0163] To improve the accuracy of the movement of the actuator 123 along, for example, vertical directions, such as... Figure 39 As shown, the dust collection base station 100 also includes a guide member 124, which defines a guide groove 1241 extending along a preset direction. The action member 123 moves along the guide groove 1241, which can further improve the accuracy of the movement path of the action member 123, thereby improving the reliability and stability of the action member 123 in changing the opening and closing state of the dust collection container 210.

[0164] In some embodiments, such as Figures 34 to 36 , Figure 38 As shown, the actuator 123 has a guide post 1231, and the guide member 124 has a guide groove 1242 extending in a preset direction (e.g., vertical). The guide post 1231 passes through the guide groove 1242 and is limited by the snap ring 129 to connect the actuator 123 to the base station body 110. When the actuator 123 moves in, for example, vertical direction, the guide post 1231 passes through the guide groove 1242 and moves along the guide groove 1242. In this way, the guide post 1231 can further guide and support the movement of the actuator 123, and the actuator 123 is movably set on the base station body 110 by the positioning post and the snap ring 129, thereby improving the accuracy of the movement path and the stability of the movement.

[0165] Please refer to Figure 34 and Figure 35As shown, the actuating member 123 has a positioning groove 1234, and the abutting part 12211 extends into the positioning groove 1234 and abuts against the groove wall of the positioning groove 1234. Thus, when the transmission member 1221 drives the abutting part 12211 to rotate in the positioning groove 1234, the abutting part 12211 pushes against the groove wall of the positioning groove 1234, thereby driving the actuating member 123 to move vertically, for example. For example, the actuating member 123 is a cuboid plate structure, the positioning groove 1234 is a rectangular groove, and the abutting part 12211 is a cam with a cross section. The cam is set in the rectangular groove, and the width of the rectangular groove is smaller than the maximum profile dimension of the cam. Thus, when the cam rotates, it can push the actuating member 123 to move.

[0166] In a specific implementation of the base station body 110 provided in 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 Figure 30 and Figure 31 , Figure 41 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. 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, forward, so that the drive shaft of the drive motor 1211 drives The worm gear rotates, driving the transmission component 1221 (e.g., a gear) to rotate around its own axis. The abutment portion 12211 on the transmission component 1221 abuts against the actuating component 123. When the transmission component 1221 rotates around the axis of rotation to different angles, the distance between the abutment portion 12211 and the axis of rotation in a preset direction is different. Thus, the relative rotation of the transmission component 1221 and the actuating component 123 drives the movement of the actuating component 123, causing the actuating component 123 to move the limiting component 125 towards the closed position. The limiting component 125 then pushes the bottom cover 220 of the dust collection container 210 upwards until the actuating component 123 is in the closed position, achieving automatic closing of the bottom cover 220 (e.g., ...). Figures 32 to 33 , Figure 42 (As shown in the diagram); when the bottom cover 220 is closed, the drive motor 1211 reverses, so as to drive the transmission component 1221 to reverse around the axis of rotation via the worm gear. The transmission component 1221 then drives the action component 123 to move in the opposite direction, so that the action component 123 moves in the opposite direction (for example, vertically downward) until the action component 123 is in the release 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 closed, and improve the user experience.

[0167] 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 to make the transmission member rotate around a rotation axis. The action member is connected to the transmission member and moves along a preset direction under the drive of the transmission member. This improves the accuracy and reliability of the action member's movement path, allowing the action member to change the opening and closing state of the dust collection container through its own movement. This achieves the purpose of automatically closing the dust collection container through the transmission member, eliminating the need for manual closing of the dust collection container. This avoids the problem of residual dust overflowing and causing secondary pollution when manually closing the container, thus improving the user experience.
