Description

Technical Field

[0001] This disclosure belongs to the field of cleaning equipment technology, specifically relating to a dust collection base station and a cleaning system. Background Technology

[0002] Handheld vacuum cleaners and similar vacuuming devices typically use negative pressure generated by a fan to draw dust into a dust cup, which is then emptied after use. However, due to the limited capacity of the dust cup, dust accumulates and fills the cup over time. To improve the user experience, existing cleaning systems incorporate a dust collection station into the vacuum cleaner, allowing the device to connect and collect dust after cleaning.

[0003] After docking, the dust collection base station can store the vacuum cleaner and, with the dust cup open, absorb the dust into the internal dust bag or dust box, allowing the vacuum cleaner to perform cleaning tasks again. Summary of the Invention

[0004] The purpose of this disclosure is to provide a dust collection base station and a cleaning system that can ensure a tight connection between the dust cup and the base station after the dust cup is connected to the dust collection base station, thereby preventing dust leakage.

[0005] To achieve the above objectives, the technical solution provided in this disclosure is as follows:

[0006] In a first aspect, this disclosure provides a dust collection base station for docking with a dust cup of a vacuum cleaner. The dust cup has a cover with a dust discharge port that can be opened and closed. The dust collection base station includes a dust collection chamber, a docking component, an elastic sealing ring, and a snap-fit ​​component. The dust collection chamber is used to collect dirt from the dust cup. The docking component forms a docking space, and the docking component has a side opening for the dust cup to be pushed into the docking space at least partially in a horizontal direction. The side wall of the docking component is provided with a dust collection port communicating with the dust collection chamber. The elastic sealing ring is disposed around the dust collection port and is used to ensure airtight communication between the dust collection port and the dust discharge port after the dust cup docks with the docking component. The snap-fit ​​component is disposed on the docking component and is used to lock the dust cup after the dust cup docks with the docking component, so that the dust cup abuts against the elastic sealing ring.

[0007] In one or more embodiments, the elastic sealing ring includes a body portion and an elastically deformable sealing lip, the body portion being connected to the mating member and arranged along the periphery of the dust collection port, and the sealing lip protruding from the body portion toward the dust cup mating side.

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0034] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0035] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. In the embodiments shown in this disclosure, directional representations such as up, down, left, right, front, and back are relative and are used to explain the relative structure and movement of different components in this disclosure. These representations are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, then these representations are considered to change accordingly.

[0036] As household and commercial cleaning equipment continues to develop, vacuum cleaners are evolving towards automation and maintenance-free operation, with automatic dust removal in collaboration with a dust collection station becoming the mainstream trend. Vacuum cleaners are typically equipped with a removable dust cup for temporary storage of dust and dirt, which is then automatically cleaned in conjunction with the dust collection station.

[0037] Existing dust collection base stations mostly employ a simple channel-type docking structure. Users align the dust cup with the dust collection port of the base station to connect the exhaust port and the collection port. However, due to factors such as manufacturing tolerances, user operation deviations, and external vibrations, it is often difficult to ensure precise alignment between the exhaust port and the collection port during the docking process. This slight misalignment, though seemingly minor, can lead to gaps at the interface, resulting in insufficient airtightness. During negative pressure suction, external air seeps in through these gaps, weakening the cleaning efficiency, causing incomplete dirt transfer, and even prolonging cleaning time and increasing energy consumption. More seriously, these gaps can also become channels for dust to escape, causing secondary pollution and affecting user health and environmental hygiene.

[0038] Based on the analysis of the shortcomings of existing technologies, the technical solution disclosed herein proposes an overall design concept based on the combination of geometric constraints, elastic sealing, and mechanical pre-tightening: automatic alignment is achieved by limiting the horizontal pushing path and final position of the dust cup; a deformable elastic sealing structure is set at the airflow channel interface to give it the ability to absorb tolerances and adaptive compensation; and a locking or pre-tightening structure provides continuous axial clamping force after the dust cups are docked to maintain the stability of the airtight fit.

[0039] Please refer to Figure 1 and Figure 2 As shown, a cleaning system in one embodiment of the present disclosure includes a vacuuming device 1 and a dust collection base station 2. The vacuuming device 1 includes a detachable dust cup 10 that can be docked with the dust collection base station 2. The dust cup 10 includes a cup body 11 and a cover 12. The side wall of the cup body 11 is provided with a dust discharge port 111, and the cover 12 is closable and covers the dust discharge port 111.

[0040] Please refer to Figure 3 and Figure 4As shown, the dust cup 10 serves as the docking element between the vacuum cleaner 1 and the dust collection base station 2. It can dock with the dust collection base station 2 and can be detached from the vacuum cleaner 1. This detachable design facilitates independent emptying and cleaning of the dust cup 10 by the user. The dust cup 10 is further composed of a cup body 11 and a cover body 12, forming a closed dirt-containing cavity. The cup body 11, as the main frame of the dust cup 10, can be made of an impact-resistant and well-sealing material. It has a dust discharge port 111 on its side wall. The position and size of the dust discharge port 111 match the dust collection port 223 of the dust collection base station 2, thereby achieving connection of the dust discharge path during docking.

[0041] The dust vent 111 on the side wall of the cup body 11 is designed to be more horizontally exposed than the bottom wall, facilitating horizontal docking with the base station. Meanwhile, the cover 12 is closable and can be placed over the dust vent 111. One end of the cover is connected to the corresponding position on the side wall of the cup body 11 via a hinge structure, forming a rotating mechanism with the hinge as the axis. This allows the cover 12 to completely cover the dust vent 111 in the closed state to maintain the airtightness of the dust cup 10, and in the open state, it flips outward to expose the dust vent 111.

[0042] The dust collection base station 2 serves as an auxiliary collection unit of the system and is connected to the dust cup 10 of the vacuum cleaner 1 via a horizontal push-in docking method. The dust cup 10 can be pushed in from the side of the base station. After the dust discharge port 111 is aligned with the dust collection channel of the base station, the cover 12 can be automatically opened by the trigger mechanism of the base station, thereby transferring the dirt in the cup 11 to the base station through negative pressure suction.

[0043] In one exemplary embodiment, please refer to Figures 3 to 6 As shown, the cover 12 of the dust cup 10 includes a hinged end 121 and a free end 122. The hinged end 121 is hinged to the side wall of the cup body 11, and the free end 122 is provided with a retaining part 123. The bottom of the cup body 11 is provided with a locking member 13 for locking the cover 12. The locking member 13 includes a hinged part 131, a hook part 132, and a pressing part 133 provided between the hinged part 131 and the hook part 132. The hinged part 131 is hinged to the cup body 11, and the locking member 13 can rotate around the hinged part 131 as a fulcrum to switch between an unlocked position and a locked position. When the cover 12 is closed, the hook part 132 can engage with the retaining part 123 in the locked position to lock the cover 12. Pressing the pressing part 133 can switch the locking member 13 to the unlocked position to release the engagement between the hook part 132 and the retaining part 123 and release the lock on the cover 12.

[0044] The lid 12 and the cup 11 are rotatably connected at the side wall via a hinge end 121. The hinge axis is arranged relative to the dust outlet 111 of the cup 11, allowing the lid 12 to swing stably around this axis between open and closed states. The free end 122 of the lid 12 is provided with a retaining part 123 for engaging with the bottom locking member 13 of the cup 11. The retaining part 123 forms a force-bearing surface for guiding and positioning at the end of the closing stroke of the lid 12, so that the free end 122 approaches and engages with the hook part 132 of the locking member 13 along a predetermined trajectory.

[0045] To avoid interference and contamination of the dust extraction area, a locking element 13 is located at the bottom of the cup body 11. The locking element 13 includes a hinge portion 131 that is rotatably connected to the cup body 11, a hook portion 132 for engaging with the holding portion 123, and a pressing portion 133 for manual or mechanical triggering. These three elements are arranged sequentially along the force transmission path, forming a single-arm lever with the hinge portion 131 as the fulcrum. Through this lever structure, the locking element 13 can be repeatedly switched between two stable states: locked and unlocked. In the closed state, it provides a reliable retaining force to the free end 122 of the cover 12 to lock the cover 12.

[0046] The hinge end 121 of the lid 12 serves as a rotation guide and positioning function, ensuring the coaxiality and end face fit accuracy of the lid 12 and the side wall of the cup 11 during assembly and multiple opening and closing processes; the holding part 123 of the free end 122 matches the hook part 132 through surface contact or line contact features, so that the end point of the stroke in the closing direction has a self-guided characteristic, reducing end misalignment caused by operational differences.

[0047] The hinge portion 131 of the locking member 13 is positioned relative to the bottom of the cup body 11 to prevent the opening and closing load from being directly applied to the periphery of the dust outlet 111, thus avoiding deformation. The hook portion 132 is arranged facing the free end 122 of the cover body 12, and its hook or flange shape creates a mechanical self-locking tendency, maintaining stable engagement even under vibration and negative pressure disturbance. The pressing portion 133 is located in an easily accessible position, allowing for direct pressing by the user or indirect actuation by the unlocking trigger component of the base station during system docking. Through this arrangement, the opening and closing force is input from the pressing portion 133, converted into the rotational release of the hook portion 132 via the hinge portion 131, causing the hook portion 132 to separate from the holding portion 123. Under the action of its own restoring force or external driving force, the cover body 12 rotates in the opening direction to open the dust outlet 111.

[0048] When the cover 12 is closed, the retaining portion 123 of its free end 122 engages downwards or inwards with the hook portion 132 of the locking member 13, achieving mechanical engagement. This engagement is achieved by matching the barbed edge of the hook portion 132 with the groove of the retaining portion 123, forming a self-locking mechanism to prevent the cover 12 from being accidentally opened during transportation or storage, thereby maintaining the overall airtightness of the dust cup 10. When the pressing portion 133 is pressed, the locking member 13 rotates around the hinge portion 131 as a fulcrum. The pressing force of the pressing portion 133 is transmitted to the hook portion 132, causing it to disengage from the retaining portion 123, switching to the unlocked position, releasing the lock and allowing the cover 12 to be opened under external force.

[0049] Specifically, please refer to Figure 3 and Figure 5 As shown, a torsion spring 124 is provided between the hinge end 121 and the cup body 11. The torsion spring 124 is used to provide the elastic force to drive the cover 12 to rotate and open the dust outlet 111. A reset member 134 is provided between the pressing part 133 and the bottom wall of the cup body 11. The reset member 134 is used to provide the driving force to keep the locking member 13 in the locked position.

[0050] A torsion spring 124, positioned between the hinge end 121 and the cup body 11, is arranged along the hinge axis of the cover 12. Preferably, it wraps around the hinge axis, forming contact with both the cover 12 and the cup body 11. This allows the torsion spring 124 to generate pre-torque and store energy as the cover 12 rotates from the open to the closed position. Consequently, when the locking member 13 releases its constraint on the free end 122 of the cover 12, the torsion spring 124 releases its stored energy and outputs a torque in the opening direction, driving the cover 12 to rotate around the hinge axis, thus quickly opening the dust outlet 111. By setting the initial pre-tension angle of the torsion spring 124, the cover 12 can maintain a certain opening tendency even when closed, thereby suppressing loosening due to operational vibrations. The elastic working range of the torsion spring 124 matches the stroke of the cover 12, ensuring responsiveness for rapid opening and avoiding impact and interference caused by excessive rebound.

[0051] To keep the lid 12 closed when not in a dust-free state, a reset member 134 (which can be implemented by an elastic element) is provided between the bottom wall of the cup body 11 and the pressing part 133 of the locking member 13. The reset member 134 can be arranged axially or tangentially so that the reset force acts on the rotation fulcrum system of the locking member 13, forming a reset torque with the hinge part 131 as the fulcrum, so that the locking member 13 is naturally in the locked position.

[0052] After the cover 12 is closed and the hook portion 132 engages with the holding portion 123, the reset member 134 provides a continuous and stable holding force to counteract the disturbances to the locked state caused by suction, handling impact, and environmental vibration. When unlocking is required, the pressing portion 133 is displaced by an external actuation (e.g., by the base station unlocking component or the user's finger), overcoming the reset force of the reset member 134, causing the locking member 13 to pass its mechanical equilibrium point of rotation, and the hook portion 132 separates from the holding portion 123 to complete the unlocking. After the unlocking actuation is removed, the reset member 134 can reset the locking member 13 to the locked position, ensuring that the hook portion 132 can re-engage with the holding portion 123 after the cover 12 is closed again, reducing the risk of dust leakage caused by misoperation or forgetting to lock.

[0053] In one exemplary embodiment, please refer to Figure 4 and Figure 6 As shown, the dust cup 10 includes a base plate 14 fixedly connected to the bottom wall of the cup body 11, and a locking member 13 is disposed between the base plate 14 and the bottom wall of the cup body 11. The base plate 14 is provided with a through hole 141 adapted to the pressing part 133. The pressing part 133 is located in the through hole 141 and the locking member 13 can be switched to the unlocked position by pressing through the through hole 141.

[0054] The bottom plate 14 of the dust cup 10 is fixedly connected to the bottom wall of the cup body 11 to form a relatively closed clamping cavity. The locking member 13 is accommodated in this cavity and is supported for rotation / positioning by the bottom wall. The bottom plate 14 acts as a covering and limiting member to confine the locking member 13 within the clamping cavity. A through hole 141 is provided on the bottom plate 14, which is axially aligned with the pressing part 133. The position of the opening of the through hole 141 is set relative to the assembly reference of the cup body 11 and the cover body 12, so that the pressing force can be directly applied to the pressing part 133 in a direction approximately perpendicular to the bottom wall, thereby reducing the interference of the lateral component force on the rotation of the locking member 13. The pressing part 133 is located in the through hole 141 and can obtain the necessary guidance under the constraint of the hole wall to avoid swaying and eccentricity during the unlocking actuation process. The assembly gap between the edge of the through hole 141 and the pressing part 133 is designed to ensure smooth actuation without causing obvious shaking.

[0055] The base plate 14 provides an independent installation and protection space for the locking component 13, reducing the impact of dust accumulation on rotational sensitivity and reset stability. It also moves the unlocking interface from the periphery of the dust outlet 111 to the bottom of the cup body 11, reducing the probability of it being directly washed away by airflow under the negative pressure of dust removal. The through hole 141, as an exposed actuation window, provides a path for user finger pressure or the base station unlocking component. Combined with the end profile of the pressing part 133, it facilitates pressing operations. When the system uses automatic base station unlocking, the axial layout of the through hole 141 facilitates short-stroke actuation of the base station's unlocking trigger in the vertical direction.

[0056] In one exemplary embodiment, please refer to Figures 1 to 3 As shown, the dust collection base station 2 includes a dust collection chamber 21, a docking component 22, an elastic sealing ring 23, and a fastening component 24. The dust collection chamber 21 is used to collect dirt in the dust cup 10. The docking component 22 encloses and forms a docking space 221. The docking component 22 has a side opening 222 for the dust cup 10 to be pushed into the docking space 221 at least partially in the horizontal direction. The side wall of the docking component 22 is provided with a dust collection port 223 that communicates with the dust collection chamber 21. The elastic sealing ring 23 is arranged around the dust collection port 223 to ensure airtight communication between the dust collection port 223 and the dust discharge port 111 after the dust cup 10 is docked with the docking component 22. The fastening component 24 is provided on the docking component 22 to lock the dust cup 10 after it is docked with the docking component 22, so that the dust cup 10 is held against the elastic sealing ring 23.

[0057] The dust collection chamber 21, serving as a negative pressure and waste collection space, connects to the dust collection port 223 on the side wall of the docking member 22, forming a short-path airflow from the dust cup 10 to the base station interior, thereby reducing flow losses and improving extraction efficiency. The docking member 22 encloses a docking space 221 for accommodating the dust cup 10, and features a horizontal or near-horizontal side opening 222 facing outwards, allowing the dust cup 10 to be pushed in horizontally or near-horizontally. The top of the docking space 221 can have an open layout, allowing the user to lift the dust cup 10 vertically after docking, thus completing docking and disassembly in both horizontal push-in and vertical pull-out operation modes.

[0058] An elastic sealing ring 23 is arranged around the dust collection port 223, and it is used to establish a compressible circumferential sealing interface between the wall of the dust cup 10 and the mating part 22. When the mating is completed, the elastic sealing ring 23 is compressed in the normal direction to generate contact pressure, forming a continuous circumferential fit, and through its own elastic deformation, it can accommodate the small posture / size deviations between the dust cup 10 and the mating part 22, so as to suppress leakage caused by local non-tightening or uneven gaps.

[0059] The snap fastener 24 is provided on the mating part 22 to lock and retain the dust cup 10 after it is in place, thereby restricting the dust cup 10 from moving along the mating direction. Figure 1 The dust cup 10 is reliably held against the elastic sealing ring 23 by exiting in the opposite direction of the X direction (in the middle) to ensure that it does not loosen under the action of operating vibration and airflow impact; on the other hand, a stable pre-tightening force is applied to the sealing interface so that the dust cup 10 is reliably held against the elastic sealing ring 23, thereby maintaining the stability of airtight connection throughout the entire dust removal process.

[0060] In one exemplary embodiment, please refer to Figure 3 and Figure 8 As shown, the elastic sealing ring 23 includes a main body 231 and an elastically deformable sealing lip 232. The main body 231 is connected to the mating member 22 and arranged along the periphery of the dust collection port 223. The sealing lip 232 protrudes from the main body 231 toward the mating side of the dust cup 10.

[0061] Optionally, the elastic sealing ring 23 is made of an integrally molded or composite-molded elastic material (such as silicone rubber or thermoplastic elastomer), including two main functional areas: the main body 231 and the sealing lip 232. The main body 231 is generally annular or rectangular frame-shaped. The main body 231 is continuously arranged along the periphery of the dust collection port 223, providing annular support and positioning, so that the elastic sealing ring 23 obtains a defined reference position in both the radial and axial directions. It bears the load caused by the assembly pre-tightening and running vibration between the dust cup 10 and the mating part 22, and evenly transfers the load to the rigid structure of the mating part 22, avoiding deformation and loosening caused by localized stress concentration.

[0062] The sealing lip 232 is located on the cup-side boundary of the main body 231 and protrudes into the docking space 221. Its free edge preferentially contacts the sealing docking surface of the dust cup 10 during docking, forming a fit relationship that evolves from line contact to surface contact during the docking process of the dust cup 10. As the retaining mechanism such as the snap fastener 24 applies axial pre-tightening at the docking end position, the sealing lip 232 undergoes elastic deformation under pressure along the normal direction, forming a continuous circumferential sealing band. This band can simultaneously accommodate axial, radial, and a small amount of angular deviation caused by lateral pushing, reducing the risk of local non-tightening and micro-gap caused by assembly tolerances, wear, and thermal expansion and contraction.

[0063] Under negative pressure suction conditions, the pressure difference further causes the sealing lip 232 to come into contact with the dust cup 10, forming a seal that is self-reinforced by the negative pressure. Under disassembly conditions, the sealing lip 232 releases its deformation according to its rebound characteristics, thus balancing sealing reliability and durability under repeated operation. The geometric shape of the sealing lip 232 matches the outer wall of the dust discharge port 111 of the dust cup 10, so that the sealing interface remains stable in the three stages of insertion, final pressing, and operation maintenance, ensuring circumferential airtightness at the air passage connection.

[0064] Specifically, please refer to Figure 8 As shown, the sealing lip 232 includes a connecting portion 233 and a lip portion 24. The connecting portion 233 protrudes from the inner periphery of the main body portion 231 toward the mating side of the dust cup 10, and the lip portion 24 extends from the end of the connecting portion 233 away from the main body portion 231 toward the outer periphery of the dust collection port 223, so as to form a clearance space 235 between the main body portion 231 and the lip portion 24, which allows the sealing lip 232 to deform.

[0065] The sealing lip 232 adopts a two-section configuration of connecting part 233 and lip 24. Connecting part 233 protrudes from the inner periphery of main body 231 toward the mating side of dust cup 10, serving as a flexible transition zone between sealing lip 232 and main body 231, and bearing the function of deformation and load transfer. Lip 24 extends from the end of connecting part 233 away from main body 231 toward the outer periphery of dust collection port 223. Its free edge preferentially contacts the sealing mating surface of dust cup 10 during the mating process, gradually transitioning from line contact to surface contact as pre-tightening, forming a continuous circumferential sealing band. The extension relationship of connecting part 233 relative to main body 231 concentrates the main bending and shear deformation of lip 24 in the vicinity of connecting part 233, thereby decoupling the elastic displacement required for sealing from the positioning and load-bearing function of main body 231. This ensures that sealing lip 232 has sufficient conformability during assembly and operation, while avoiding adverse effects on the fixing relationship between main body 231 and mating part 22.

[0066] The clearance space 235 formed between the main body 231 and the lip 24 provides room for the elastic deformation of the sealing lip 232. The existence of this space, on the one hand, allows for the travel margin of the lip 24 after bending, springback and slight torsion under pressure, reducing the risk of local overpressure or flange due to assembly tolerances, posture deviations and long-term wear; on the other hand, by weakening the constraint rigidity at the root of the lip 24, the sealing lip 232 can still maintain a uniform and continuous contact pressure distribution under axial preload, radial offset and slight angular mismatch conditions.

[0067] In one exemplary embodiment, please refer to Figure 7 and Figure 9 As shown, the docking part 22 includes a connecting part 224, one end of which is connected to the dust collection port 223 and the other end is connected to the dust collection chamber 21; the port of the connecting part 224 connected to the dust collection port 223 is provided with a fitting groove 2241, and the main body part 231 is provided with a fitting part 236 that fits into the fitting groove 2241 to seal and fix the main body part 231 and the port of the connecting part 224.

[0068] The docking part 22 functionally forms a continuous airflow channel from the dust collection port 223 to the dust collection chamber 21. The connecting part 224 serves as a rigid bridge structure between the docking area and the internal dust collection space, defining the axis and position reference of the air path, allowing negative pressure to be transmitted within a short path. The connecting part 224 is generally tubular or bent channel-shaped, with one end directly connected to the inner edge opening of the dust collection port 223, forming a smooth transition interface to ensure that the dirt discharged from the dust discharge port 111 flows in smoothly; the other end extends to the upper part or side of the dust collection chamber 21.

[0069] To achieve stable installation and airtight closure of the sealing element at the interface between the connecting part 224 and the mating part, a fitting groove 2241 is provided around the port of the connecting part 224 connected to the dust collection port 223. This fitting groove 2241 serves as the assembly reference and force-bearing base for the main body 231 of the sealing ring. The main body 231 of the elastic sealing ring 23 forms a corresponding fitting part 236, which is inserted into the fitting groove 2241 by pressing or other fitting methods, thereby obtaining positioning and constraint in the radial and axial directions. This ensures that the posture and position of the main body 231 relative to the port of the connecting part 224 remain consistent, and stably transmits the preload from the dust cup 10 side to the mating part 22.

[0070] In one exemplary embodiment, please refer to Figure 3 , Figure 7 and Figure 8 As shown, the docking member 22 includes a support portion 225 for supporting the dust cup 10, and a main body portion 231 is provided with a support portion 237 that protrudes relative to the support portion 225. A guide surface 238 is provided at the junction of the support portion 237 and the support portion 225. The guide surface 238 extends from the top of the support portion 237 to the support surface of the support portion 225 and is used to guide the bottom plate 14 of the dust cup 10 to transition from the support surface to the top surface of the support portion 237 during the pushing process.

[0071] The docking member 22 is provided with a support portion 225 for supporting the dust cup 10. The support portion 225 provides a support surface that matches the bottom plate 14 of the dust cup 10, so as to bear the weight and the guiding reaction force transmitted from the dust cup 10 during the lateral pushing process. Based on this, the main body 231 of the elastic sealing ring 23 arranged around the dust collection port 223 forms a support portion 237 that is slightly raised relative to the support portion 225. The support portion 237 is in the shape of a boss. A guide surface 238 is provided at the junction of the support portion 237 and the support portion 225. The guide surface 238 smoothly transitions from the top of the support portion 237 to the support surface, preferably a slope or arc transition. At the end of the horizontal pushing of the dust cup 10, the bottom plate 14 first contacts the support surface and climbs along the guide surface 238, and finally transitions from the support surface to the top surface of the support portion 237 for support and sealing, completing the posture correction and final positioning.

[0072] Specifically, please refer to Figure 7 As shown, the docking part 22 includes a limiting part 226 that is adapted to the side wall contour of the dust cup 10. The limiting part 226 and the supporting part 225 together form a docking space 221. The limiting part 226 includes a stop plate 2261 located opposite to the side opening 222, and guide plates 2262 located on both sides of the stop plate 2261 and connected to the stop plate 2261. The guide plates 2262 are used to limit the pushing path of the dust cup 10, and the stop plate 2261 is used to limit the pushing depth of the dust cup 10.

[0073] The docking part 22 is provided with a limiting part 226 that matches the shape of the side wall of the dust cup 10. The limiting part 226 and the supporting part 225 enclose a docking space 221 for accommodating the dust cup 10. Its planar profile is preferably a near-U-shaped structure surrounding the dust cup 10, so as to provide an envelope-like constraint on the lateral drift and attitude deviation of the dust cup 10 during the docking process.

[0074] The limiting part 226 includes a stop plate 2261 located on the side opposite to the side opening 222 and guide plates 2262 respectively arranged on both sides of the stop plate 2261 and connected thereto. The guide plates 2262 form an inlet channel extending in the docking direction under the joint action of the supporting part 225. The width of the channel matches the contour of the side wall of the dust cup 10 and can be set with a small convergence so as to form a guide path when the dust cup 10 is gradually pushed in, and suppress lateral deviation or pitch caused by differences in user operation or assembly tolerance.

[0075] The stop plate 2261 is arranged with openings 222 on opposite sides, which, together with the support portion 225, mark the final depth of the dust cup 10, ensuring a definite positioning of the dust cup 10 upon reaching its final position. This also provides a geometric reference for the subsequent pre-tightening applied by the snap-fit ​​member 24 and the pressure applied to the sealing ring. To reduce edge damage and frictional disturbance, the guide surface of the guide plate 2262 facing the mating space 221 can be provided with rounded corners or small chamfers while maintaining surface continuity.

[0076] In one exemplary embodiment, please refer to Figure 4 and Figure 7 As shown, the fastener 24 includes a first fastening portion 241 and a second fastening portion 242 for locking the dust cup 10 after it is docked in place. The first fastening portion 241 is retractably disposed on the support portion 225 and is configured to extend at least partially out of the support surface of the support portion 225 when the dust cup 10 is not docked. The second fastening portion 242 is retractably disposed on the guide plate 2262 and is configured to extend at least partially out of the guide surface of the guide plate 2262 when the dust cup 10 is not docked. During the docking process of the dust cup 10, the first fastening portion 241 and the second fastening portion 242 are squeezed back by the dust cup 10 and spring back to engage with the dust cup 10 after docking in place.

[0077] The fastener 24 employs a double-fastener arrangement distributed between the support portion 225 and the guide plate 2262. The first fastener portion 241 is retractably disposed on the support portion 225 and at least partially protrudes above the support surface when the dust cup 10 is not docked. The second fastener portion 242 is retractably disposed within the guide plate 2262 and at least partially protrudes from the guide surface when the dust cup 10 is not docked. When the dust cup 10 is pushed into the docking space 221 along the side opening 222, its base plate 14 and side wall sequentially press against the first fastener portion 241 and the second fastener portion 242, causing them to retract and make way against their own elastic force. As the dust cup 10 reaches the docking end position, the two fasteners spring back and engage with the corresponding engaging parts of the dust cup 10, forming a retention mechanism for the completed docking.

[0078] The first latching part 241 is arranged on the support part 225, which takes priority in the reverse limiting function along the docking direction. The locking force applied after its rebound is converted into pre-tightening of the sealing interface. The second latching part 242 is arranged on the guide plate 2262, which takes priority in suppressing lateral retraction and small-angle swing. Through cooperation with the limiting part 226, it restrains the lateral swing and yaw of the dust cup 10, thereby obtaining higher anti-disturbance ability and more uniform sealing pressure. Since the locking direction of the latching part 24 is designed to mainly restrict the reverse withdrawal along the docking direction, the vertical withdrawal path is geometrically decoupled from the engagement surface. After completing the dust cleaning process, the user can lift the dust cup 10 along the top opening of the docking space 221 without blocking or interfering with the latch, thereby realizing the disassembly and assembly mode of lateral docking and vertical withdrawal.

[0079] Specifically, please refer to Figure 4 and Figure 7 As shown, a slot 142 is formed on the bottom plate 14 of the dust cup 10 for engaging with the first latching part 241. The opening of the slot 142 is aligned with the pop-out direction of the first latching part 241, so that the first latching part 241 is gradually compressed during the process of the dust cup 10 being pushed in laterally and then elastically rebounds at the final position before entering the slot to achieve locking.

[0080] A locking block 112 is provided on the outer periphery of the side wall of the cup body 11 to cooperate with the second locking part 242. The locking block 112 is preferably a partially protruding or embedded component. The second locking part 242 is pushed back by the side wall of the dust cup 10 and rebounds at the final position, forming a lateral engagement with the locking block 112. This lateral engagement provides restraint on the lateral swing and yaw of the dust cup 10, and together with the first locking part 241, it forms a multi-point spatial locking, so that the dust cup 10 obtains both the reverse withdrawal restriction along the docking direction and the lateral posture stability after docking, thereby suppressing micro-displacement and micro-rotation caused by the start and stop of the motor 26, airflow impact and handling impact, and ensuring the circumferential fit of the sealing ring and uniform contact pressure.

[0081] In one exemplary embodiment, please refer to Figure 3 and Figure 7 As shown, the support part 225 is provided with an unlocking part 227 for opening the cover 12. After the dust cup 10 is in place, the unlocking part 227 can trigger the locking member 13 of the cover 12 to perform an unlocking operation, so that the locking member 13 releases the lock on the cover 12. After the cover 12 is unlocked, it opens towards the inside of the dust collection port 223.

[0082] The supporting part 225 has an integral or fixed unlocking part 227 in the docking end position area near the bottom plate 14 of the dust cup 10. The unlocking part 227 protrudes in the direction towards the dust cup 10. Its spatial position is arranged opposite to the pressing part 133 of the bottom locking member 13 of the dust cup 10 along the docking axis, so that the two make axial contact after the dust cup 10 completes horizontal pushing, climbs through the guide surface 238 and reaches the end position height.

[0083] To ensure the reliability of the action sequence, the protrusion height and leading edge shape of the unlocking part 227 can be set as two segments relative to the supporting surface. The leading edge adopts rounded corners or small bevels to reduce the guide resistance and correct minor posture deviations. The actuation segment provides sufficient axial travel in the final position neighborhood, transmitting the pressing pressure to the pressing part 133 in a direction approximately perpendicular to the base plate 14. Thus, when the dust cup 10 is in place, the unlocking part 227 overcomes the reset torque of the locking member 13, causing it to rotate around the hinge part 131 as the fulcrum, releasing the engagement between the hook part 132 and the holding part 123 of the free end 122 of the cover 12. Under the energy stored in the torsion spring 124 at the hinge end 121, the cover 12 opens toward the inside of the dust collection port 223, and the dust discharge port 111 opens and connects to the dust collection path of the base station.

[0084] The open layout of the unlocking part 227 and the top of the docking space 221 also maintains non-interference during the unloading phase. When the user lifts the dust cup 10 vertically, the unlocking part 227 exits contact, and the locking part 13 automatically returns to the locked position under the action of the reset part 134, which is the same initial state preset for the next docking.

[0085] In one exemplary embodiment, please refer to Figure 3 As shown, the docking member 22 is provided with a closing mechanism 25 for closing the cover 12. The closing mechanism 25 includes a body 251, an elastic element 252 and a roller 253. The body 251 is slidably disposed on the docking member 22 and located inside the dust collection port 223. The roller 253 is rotatably disposed at one end of the body 251 near the docking space 221. The elastic element 252 is disposed between the body 251 and the docking member 22 to allow the roller 253 to extend from the inside of the dust collection port 223 into the docking space 221, so that when the dust cup 10 exits the docking space 221 in the vertical direction, the roller 253 can press the cover 12 to close the cover 12.

[0086] The docking member 22 is provided with a closing mechanism 25 for closing the cover 12. The closing mechanism 25 includes a body 251 that can reciprocate relative to the docking member 22, an elastic member 252 that provides pre-tightening in the direction of the docking space 221, and a roller 253 rotatably arranged at the front end of the body 251. The body 251 is placed inside the dust collection port 223 (on the side where the connecting part 224 is located), forming a guiding fit with the docking member 22, so that it slides smoothly within the stroke in the docking direction or near the docking direction; the elastic member 252 is disposed between the body 251 and the docking member 22, continuously pushing the body 251 towards the docking space 221, so that the roller 253 extends slightly from the inside of the dust collection port 223 in a stationary state and is positioned above or to the side above the movement path of the cover 12. The roller 253 is located at one end near the docking space 221. Its axis of rotation is compatible with the vertical extraction direction of the dust cup 10. It contacts the cover 12 by rolling rather than sliding, reducing friction and surface wear, and converting the pressing force into a torque that causes the cover 12 to rotate in the closing direction.

[0087] When the dust cup 10 completes cleaning and vertically exits the docking space 221, the cover 12 is in an open position and extends towards the inside of the dust collection port 223. At this time, the outer surface or edge of the cover 12 first contacts the roller 253. Under the pre-tightening action of the elastic element 252, the roller 253 applies continuous pressure to the cover 12, and through its rolling contact, the local pressing is converted into a closing drive along the closing direction, causing the cover 12 to fall back to the closed position around the hinge axis.

[0088] As the cover 12 closes, the hook portion 132 of the locking member 13 engages with the holding portion 123, and the mechanism enters a self-holding state. If the contact force fluctuates due to tolerance accumulation or operating speed differences during the closing process, the body 251 can slightly retract under the guiding constraint to absorb the impact and avoid overpressure. After the interference is released, it returns to the initial extended position under the action of the elastic member 252 to ensure that the next docking has the same state.

[0089] In one exemplary embodiment, please refer to Figure 2 and Figure 3 As shown, the dust collection base station 2 includes a motor 26, a controller 27, and a micro switch 28 disposed on the docking member 22. The controller 27 is electrically connected to the motor 26 and the micro switch 28. The micro switch 28 is configured to output a sensing signal in response to the docking of the dust cup 10. The controller 27 is configured to control the motor 26 to start in response to the sensing signal, so as to provide suction to draw the dirt in the dust cup 10 into the dust collection chamber 21.

[0090] The dust collection base station 2 includes a motor 26, a controller 27, and a micro switch 28 mounted on the docking member 22 at the electrical and control levels. The motor 26, as a negative pressure power source, is preferably located near the dust collection chamber 21 to shorten the air path and reduce energy loss; the controller 27 is electrically connected to the motor 26 and the micro switch 28 to form a signal link from docking confirmation to power output.

[0091] Microswitch 28 is installed on the force / connection path of docking member 22. Its actuating end is arranged opposite to the characteristic surface of dust cup 10 when it is docked in place (e.g., the base plate 14 of dust cup 10 or a structure rigidly associated with it). After dust cup 10 is pushed in horizontally and climbs to the final position via guide surface 238, it can reliably trigger the stroke by axial pressing, thereby outputting a docking induction signal. When the user lifts dust cup 10 vertically away, microswitch 28 resets accordingly, serving as a boundary condition for stopping suction. After receiving the induction signal from microswitch 28, controller 27 drives motor 26 to start according to preset logic, establishing a negative pressure airflow from dust collection port 223 through connecting part 224 to dust collection chamber 21, sucking the dirt in dust cup 10 into dust collection chamber 21.

[0092] In summary, the dust collection base station and cleaning system provided in this disclosure form an adaptive circumferential seal with the dust outlet after the dust cup is connected by an elastic sealing ring, absorbing assembly tolerances and posture deviations; and by locking with snap fasteners and applying axial preload, it suppresses loosening and micro-leakage caused by vibration and airflow pulsation, continuously maintaining airtightness, thereby reducing the risk of bypass leakage and dust escape, and improving negative pressure utilization and dust removal efficiency.

[0093] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0094] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
