Description

Technical Field

[0001] The present disclosure belongs to the technical field of cleaning equipment, and particularly relates to a dust collection base station and a cleaning system. Background Art

[0002] Vacuum cleaners, such as handheld vacuum cleaners, generally use the negative pressure generated by the fan to absorb dust into the dust cup that comes with the vacuum cleaner and collect it. After use, the dust cup is opened to dump the garbage. However, due to the limited capacity of the dust cup, after a period of use, dust will be deposited in the dust cup and fill up the dust cup. In order to improve the user experience, the existing cleaning system will add a dust collection base station on the basis of the vacuum cleaner, so that the vacuum cleaner can dock with the dust collection base station after completing the cleaning task. After docking, on the one hand, the dust collection base station can serve as a storage for the vacuum cleaner, and on the other hand, the dust cup is opened, and the dust collection base station absorbs the dust in the dust cup into the internal dust bag or dust box, so that the vacuum cleaner can quickly perform the cleaning task again.

DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present disclosure.

[0045] Unless expressly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0046] It is to be understood that where an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can be present. In the drawings shown in the present disclosure, the directions such as up, down, left, right, front and rear are relative, and are used to explain the structure and movement of different components in the present disclosure. When the components are in the positions shown in the drawings, these indications are appropriate. However, if the position of the elements changes, it is considered that these indications will also change accordingly.

[0047] With the wide application of handheld vacuum cleaners, users' demand for cleaning efficiency and operation convenience is constantly increasing. Although the traditional handheld vacuum cleaner can concentrate dust in the dust cup through the suction force of the fan, due to the limited volume of the dust cup, the user needs to clean the dust cup frequently. During the cleaning process, it is often necessary to manually open the cover for pouring, which not only increases the operation steps, but also easily causes dust overflow, bringing bad experience to the user.

[0048] Therefore, the prior art introduces a dust collection base station, so that the dust collection equipment can be docked with the base station after completing the cleaning, and the dust in the dust cup is transferred to a larger volume dust collection container by the base station. However, the existing dust collection base station still has a prominent problem, that is, how to automatically and reliably open the dust cup cover after docking. If the opening is not smooth or improper operation, it will not only affect the smooth transfer of dust, but also may cause dust residue or environmental pollution.

[0049] In the existing cleaning system, the dust cup of the handheld or push-in type vacuum cleaner is usually provided with a cover at the bottom, and the user relies on the cooperation of the dust collection base station to realize the opening of the cover for dust discharge. However, this bottom cover opening needs to be matched with the vertical docking mode, which easily leads to insufficient reliability of the cover during the opening or closing process, especially when there is an angle or position deviation between the dust cup and the base station, the cover often appears not completely opened or closed, which affects the dust discharge effect.

[0050] In contrast, the cover is arranged on the side wall of the dust cup, which is more likely to realize the direction matching of the opening / closing mechanism and the docking action of the dust cup, thereby obtaining higher reliability on the mechanism, especially when the cover is closed, a more stable locking can be formed. Therefore, the present disclosure proposes a new implementation idea. The core of this idea is to arrange the cover of the dust cup on the side wall of the dust cup, and realize the opening / closing of the dust cup by cooperating with the docking mode of the dust cup pushed into the dust collection base station in the horizontal direction. This structure is more consistent in the force transmission direction of the mechanism and the docking movement direction, which can improve the opening / closing reliability of the cover.

[0051] Reference Figure 1 and Figure 2As shown, the cleaning system in one embodiment of the present disclosure includes a dust suction device 1 and a dust collecting base station 2; the dust suction device 1 includes a detachable dust cup 10 that can be docked with the dust collecting base station 2, the dust cup 10 includes a cup body 11 and a cover body 12, the cup body 11 is provided with a dust discharge port 111, and the cover body 12 can be opened and closed to cover the dust discharge port 111.

[0052] The dust cup 10 on the side of the vacuum cleaner 1 is a dust holding component, including a cup body 11 for carrying and limiting the internal volume and a cover body 12 covering the dust outlet 111. The cup body 11 is preferably a shell-type structure, and a dust outlet 111 is provided on its wall. The dust outlet 111 is isolated from the outside when the cover body 12 is closed, and forms an external communication channel when the cover body 12 is opened. A composite structure of hinges and seals can be adopted between the cover body 12 and the cup body 11. One end of the cover body 12 can be repeatedly opened and closed by hinged cooperation. An annular or sheet-shaped seal is provided at the cooperation position to ensure that the cup body 11 maintains a negative pressure environment during the working stage. The other end can interact with the cup body 11 through a locking or locking structure to achieve self-closure, thereby avoiding accidental opening during vacuuming, transportation, and docking with base stations.

[0053] Reference Figure 8 As shown, the dust collection base station 2 is provided with a docking area adapted to the shape and size of the dust cup 10. The docking area can be enclosed by a guide surface 224, a limit surface 225, and a supporting surface 226 to ensure that when the dust collection device 1 is at least partially pushed into the dust collection base station 2 in the horizontal direction, the dust cup 10 slides in a predetermined direction and obtains dual constraints of posture and position at the docking position, so that the dust discharge port 111 of the cup body 11 and the entrance of the dust collection chamber 21 on the base station side are aligned in space. After the docking is completed, the cover body 12 can be turned from the closed state to the open state, and a communication path is established between the dust discharge port 111 and the dust collection chamber 21, and the dust can be transferred from the dust cup 10 to a larger volume collection container inside the base station.

[0054] In an exemplary embodiment, please refer to Figure 1 、 Figure 2 and Figure 8 As shown, the dust collection base station 2 includes a base 20 and a cover opening mechanism 23. The base 20 includes a dust collecting chamber 21 for collecting dirt in the dust cup 10. The cover opening mechanism 23 is arranged on the base 20. The cover opening mechanism 23 is configured to be triggered in response to a docking event after the dust cup 10 completes docking with the dust collection base station 2, so that the cover opening mechanism 23 performs an unlocking operation on the cover body 12 to connect the dust exhaust port 111 with the dust collecting chamber 21.

[0055] The base 20 serves as the main structure of the dust collection station 2. A dust collection chamber 21 is formed within the base 20 for receiving and storing dirt from the dust cup 10. A docking interface for docking with the dust cup 10 is reserved on the base 20. Once the dust cup 10 is docked and positioned, the dust outlet 111 of the cup body 11 can communicate with the dust collection chamber 21. To ensure airtightness and posture stability during docking, the docking interface of the base 20 is composed of a guide surface 224, a supporting surface 226, and a limiting surface 225, which are used to guide and limit the dust cup 10 during docking.

[0056] The lid opening mechanism 23 can be set inside the base 20 or near its docking interface, and the structural rigidity and installation space of the base 20 can be used to arrange the sensing and execution units. The lid opening mechanism 23 is configured to enter the actionable state only after the dust cup 10 completes the docking. The docking event can be determined by position, stroke or proximity, etc. Once determined, a trigger signal is immediately sent to the execution end to bind the unlocking action to the docking posture, avoiding the risk of dust and scattering caused by opening the lid before docking. The unlocking operation refers to applying a controlled displacement or torque to the locking structure of the cover body 12 to switch it from the locked position to the unlocked position, so that the dust outlet 111 can be connected to the dust collecting chamber 21 after the cover body 12 is unlocked and opened.

[0057] In an exemplary embodiment, please refer to Figure 7 and Figure 8 As shown, the dust exhaust port 111 of the dust cup 10 is arranged on the side wall of the cup body 11, and the base 20 includes a docking portion 22 for docking with the dust cup 10. The side wall of the docking portion 22 is provided with a dust collecting port 221 corresponding to the dust exhaust port 111. The docking portion 22 is enclosed to form a docking space with an open top and side and adapted to the dust cup 10, so that the dust cup 10 can enter the docking space from the side and dock with the docking portion 22.

[0058] The dust outlet 111 is provided on the side wall of the cup body 11, so that the cup body 11 can be docked with the base 20 sideways while maintaining a basically upright posture. The docking portion 22 on the base 20 encloses a "U"-shaped docking space with a top and side opening. The open top releases the longitudinal assembly tolerance and the swing space of the handheld body, while the side opening provides a channel for the dust cup 10 to slide in from the horizontal direction. When docking, the user only needs to push it sideways into place to complete the mechanical positioning and air path alignment, avoiding the risk of dust scattering caused by lifting or turning. In addition, pushing it in sideways is more labor-saving than lifting.

[0059] To ensure alignment accuracy, the docking portion 22 can form an enclosed structure consisting of a guide surface 224, a supporting surface 226, and a limiting surface 225. The guide surface 224 corrects the lateral and runout errors of the cup body 11 during the lateral introduction stage of the cup body 11. The supporting surface 226 bears the load and stabilizes the posture of the dust cup 10. The deep limiting surface 225 serves as a terminal surface to limit the insertion depth, so that the dust exhaust port 111 on the side wall of the cup body 11 and the dust collection port 221 on the side wall of the docking portion 22 achieve a spatial alignment relationship. The dust exhaust port 111 on the side wall of the cup body 11 and the dust collection port 221 on the side wall of the docking portion 22 are arranged face to face. When the dust cup 10 enters along the docking track and is locked in its terminal posture by the limiting surface 225, the dust exhaust port 111 can establish a communication channel with the dust collection chamber 21 after the cover body 12 is opened.

[0060] For details, please refer to Figures 4 to 7 and Figure 9 As shown, the cover body 12 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 holding portion 123; the bottom of the cup body 11 is provided with a locking member 13 for locking the cover body 12, the locking member 13 includes a hinged portion 131, a hook portion 132 and a pressing portion 133 provided between the hinged portion 131 and the hook portion 132, the hinged portion 131 is hinged to the cup body 11, and the locking member 13 can rotate with the hinged portion 131 as a fulcrum to switch between an unlocked position and a locked position; when the cover body 12 is closed, the hook portion 132 can engage with the holding portion 123 in the locked position to lock the cover body 12; pressing the pressing portion 133 can switch the locking member 13 to the unlocked position to release the engagement between the hook portion 132 and the holding portion 123, thereby releasing the lock on the cover body 12.

[0061] The hinged end 121 of the cover body 12 forms a rotating structure with the side wall of the cup body 11, so that the cover body 12 can be opened and closed controllably around a fixed axis; the holding portion 123 provided at the free end 122 serves as a force-bearing / engaging structure with the locking member 13 at the bottom of the cup body 11. The locking member 13 is arranged at the bottom of the cup body 11, and the locking member 13 can form a pivot structure with the cup body 11 through its hinged portion 131. The hinged portion 131 of the locking member 13 is connected to the bottom of the cup body 11 through a hinge or pivot structure to form a rotatable fulcrum, so that the locking member 13 can switch between the locked and unlocked positions based on the principle of a lever. The hook portion 132 is located at one end of the locking member 13 and is designed to be hook-shaped or similar to a catch structure. It can be firmly engaged with the holding portion 123 of the cover body 12 in the locked position to ensure that the cover body 12 remains in a closed state during the vacuuming process.

[0062] When the cover 12 is in the closed position, the hook portion 132 of the locking member 13 and the retaining portion 123 of the free end 122 of the cover 12 engage in a directionally meshed manner, forming a closed force loop. When the cover 12 is subjected to an external force and attempts to open, the meshing surface converts the opening force into a compressive force component along the hinge of the locking member 13, achieving self-retention and anti-vibration disengagement. The pressing portion 133 is arranged between the hinge 131 and the hook portion 132 of the locking member 13 and is designed to be a flat surface or raised structure that can be pressed by an external mechanism (such as the lid opening mechanism 23 of the dust collector base station 2). When an external force is applied to the pressing portion 133, the locking member 13 rotates in a controlled manner with its hinge 131 as the fulcrum, switching from the locked position to the unlocked position. The engagement between the hook portion 132 and the retaining portion 123 is released, and the cover 12 is then ready for opening.

[0063] The locking member 13 is arranged at the bottom of the cup body 11. On the one hand, it is convenient for the external unlocking actuator (such as the unlocking member 232 on the base station side) to directly act on the pressing part 133 under the docking condition, thereby shortening the force transmission chain; on the other hand, the bottom rigid area is usually more conducive to maintaining the geometric stability of the hinge axis and the shape and position accuracy of the meshing surface.

[0064] For further information, please refer to Figure 4 and Figure 9 As shown, a torsion spring 124 is provided between the hinged end 121 and the cup body 11, and the torsion spring 124 is used to provide an elastic force to drive the cover body 12 to rotate to open the dust exhaust port 111; a second reset member 134 is provided between the pressing portion 133 and the bottom wall of the cup body 11, and the second reset member 134 is used to provide a driving force to drive the locking member 13 to remain in the locked position.

[0065] The torsion spring 124 is arranged between the hinge end 121 of the cover 12 and the side wall of the cup body 11, forming a torsional elastic element around the hinge axis. During assembly, a pre-twist angle is applied to the torsion spring 124, so that it has an energy storage state when the cover 12 is in the closed position; when the locking member 13 is unlocked, the torque released by the torsion spring 124 acts on the cover 12 around the hinge axis, driving the cover 12 to open along a predetermined trajectory, thereby opening the dust exhaust port 111. The peak torque of the torsion spring 124 should be higher than the comprehensive resistance required for opening, while lower than the holding force of the locking member 13 to avoid the risk of self-opening when unlocked.

[0066] The second reset member 134 is disposed between the pressing portion 133 of the locking member 13 and the bottom wall of the cup body 11, generating a reset force that forces the locking member 13 toward the locked position. Its working mechanism is to stabilize the hook portion 132 of the locking member 13 in the meshing zone with the retaining portion 123 of the free end 122 of the cover body 12 through the axial and / or tangential elastic preload of the second reset member 134, thereby offsetting the disengagement tendency caused by vibration and impact, thereby achieving self-retention in the closed state. The second reset member 134 is responsible for keeping the cover body 12 locked when not unlocked, inhibiting the rotation of the cover body 12 caused by the preload of the torsion spring 124; once the pressing portion 133 is acted upon by an external actuator, causing the locking member 13 to switch to the unlocked position, the stored energy of the torsion spring 124 can be converted into an opening torque, completing the opening of the cover body 12. The second reset member 134 can be selected from compression springs, torsion springs, leaf springs, or magnetic repulsion elements, etc., depending on the installation space and the direction of force.

[0067] In an exemplary embodiment, please refer to Figures 5 to 7 As shown, the bottom wall of the cup body 11 is fixedly connected to the bottom plate 14, and the locking member 13 is limited by the bottom plate 14 between the bottom plate 14 and the bottom wall of the cup body 11. The bottom plate 14 is provided with a through hole 141 adapted to the pressing portion 133, and the pressing portion 133 is provided in the through hole 141; after the cover opening mechanism 23 is triggered, the pressing portion 133 can be pressed to switch the locking member 13 to the unlocked position.

[0068] The bottom wall of the cup body 11 is fixedly connected to a separate base plate 14. Together, they form upper and lower limit clamping layers for the locking member 13, confining it within the narrow cavity between the bottom wall and base plate 14. Base plate 14 provides rigid support and an assembly reference for the locking member 13, mitigating axis drift caused by deformation of the cup body 11 bottom wall or the accumulation of manufacturing tolerances. It also acts as a dust shield, preventing dust from outside the cup body 11 from directly invading the locking mechanism cavity, thereby enhancing long-term reliability.

[0069] To enable the external actuator to control the locking member 13, a through-hole 141 is provided on the base plate 14, matching the pressing portion 133. When in the locked position, the pressing portion 133 extends into the window of the through-hole 141. The diameter and shape of the through-hole 141 match those of the pressing portion 133 to prevent frictional locking and binding. The hole opening can be chamfered or rounded to reduce stress concentration.

[0070] When the dust cup 10 is docked with the dust collecting base station 2 and the cover opening mechanism 23 is triggered, the outer execution end (such as the push rod / push arm / drive pin) can establish controlled contact with the pressing part 133 through the through hole 141 of the bottom plate 14, and apply displacement or force to the pressing part 133 along a predetermined force line, driving the locking part 13 to rotate around its hinge part 131 and switch from the locked position to the unlocked position; after unlocking, the cover body 12 can be opened under the action of a preset elastic element (such as a torsion spring 124), so that the dust exhaust port 111 is connected to the dust collecting chamber 21.

[0071] For details, please refer to Figure 7 and Figure 8 As shown, the bottom wall of the docking part 22 is provided with a first snap portion 222, the side wall is provided with a second snap portion 223, the bottom plate 14 is provided with a slot portion 142 adapted to the first snap portion 222, and the side wall of the cup body 11 is provided with a block portion 112 adapted to the second snap portion 223; after the dust collection equipment 1 is at least partially pushed into the dust collecting base station 2 in the horizontal direction so that the dust cup 10 is docked with the docking part 22, the first snap portion 222 is engaged with the slot portion 142, and the second snap portion 223 is engaged with the block portion 112.

[0072] The docking portion 22 is provided with a first snap portion 222 on the bottom wall and a second snap portion 223 on the side wall, which respectively form two sets of independent lateral snap-fit ​​structures with the slot portion 142 on the bottom plate 14 of the dust cup 10 and the block portion 112 on the side wall of the cup body 11. During the docking process, when the dust cup 10 slides along the guide surface of the docking portion 22 to the end stroke, the bottom plate 14 engages with the first snap portion 222 and enters the slot portion 142. The side wall of the cup body 11 cooperates with the second snap portion 223 and its corresponding block portion 112 under lateral pressure to form a lateral constraint. The first snap portion 222 can be provided with an introduction chamfer or inclined surface on the buckle side, and matched with the entrance of the slot portion 142 to reduce the insertion force; the second snap portion 223 can adopt a snap arm with elastic yield or a partially compressible covering body to absorb shape and position errors, and at the same time generate a stable holding force after being fully inserted.

[0073] In an exemplary embodiment, please refer to Figures 3 to 6 and Figure 10 As shown, the cover opening mechanism 23 includes an unlocking component 230 for unlocking the locking member 13 of the cover body 12. The unlocking component 230 includes a driving member 231 and an unlocking member 232 driven by the driving member 231. The driving member 231 is configured to output linear or rotational drive so that the unlocking member 232 operates the locking member 13 to release the lock on the cover body 12.

[0074] The unlocking assembly 230 of the lid opening mechanism 23 is an unlocking execution unit and includes a driving member 231 and an unlocking member 232. The driving member 231 is configured to output a driving force in a linear or rotational form, which, through mechanical linkage, drives the unlocking member 232 to act on the locking member 13 of the dust cup 10, thereby releasing the locked state of the lid body 12. The driving member 231 can provide driving force in the form of sliding or rotation, and its structure may include mechanical elements such as pistons, connecting rods, or gears to adapt to different driving methods (such as negative pressure or motor drive).

[0075] The unlocking member 232 can be arranged as a toggle arm configuration, one end of which is connected to the driving member 231 through a hinge structure or a pin structure with an oblong hole that allows a small amount of angle / position compensation to absorb assembly tolerances and docking errors and avoid hard interference and jamming; the other end forms a working end that matches the pressing portion 133 or the toggle surface of the locking member 13, and effectively couples the displacement / torque to the locking member 13 through surface contact or line contact, so that the locking member 13 switches from the locked position to the unlocked position around its own hinge portion 131.

[0076] In an exemplary embodiment, please refer to Figures 1 to 6 As shown, the dust collection base station 2 includes a negative pressure mechanism 24 for forming a negative pressure in the dust collection chamber 21. The negative pressure formed by the negative pressure mechanism 24 can act on the driving member 231 to drive the driving member 231 to drive the unlocking member 232 to perform an unlocking operation on the locking member 13.

[0077] The dust collection base station 2 is equipped with a negative pressure mechanism 24 (such as a fan / turbine assembly), which is used to generate negative pressure in the dust collection chamber 21 within the base 20. This negative pressure not only transfers dirt from the dust cup 10 to the dust collection chamber 21, but also acts on the driving member 231 of the lid opening mechanism 23. The driving member 231 then drives the unlocking member 232 to operate the locking member 13 of the dust cup 10, completing the unlocking action of the lid 12. By utilizing the existing negative pressure resources of the dust collection base station 2, the introduction of additional driving devices (such as motors) can be avoided, thereby reducing system cost and complexity.

[0078] In other embodiments, the cover opening mechanism 23 may also adopt an electromechanical actuation concept, where the drive motor is arranged in an installation position inside the base 20 and is connected to the drive member 231 through a transmission unit, converting the motor's rotational output into linear sliding or controlled rotation of the drive member 231 as needed.

[0079] Specifically, the drive motor can be equipped with planetary / worm gear reduction or screw / ball screw, gear-rack, eccentric cam, crank slider and other transmission structures. When the driving member 231 is required to reciprocate linearly, it can be driven by a screw or gear, rack; when rotational output is required, it can be driven by a worm or gear.

[0080] In an exemplary embodiment, please refer to Figure 5 and Figure 6 As shown, the cover opening mechanism 23 includes a negative pressure chamber 233 connected to the dust collecting chamber 21, and the driving member 231 is movably arranged in the negative pressure chamber 233. The negative pressure formed by the negative pressure mechanism 24 is transmitted to the negative pressure chamber 233 through the dust collecting chamber 21, so that the driving member 231 moves under the action of the negative pressure to drive the unlocking member 232 to perform the unlocking operation.

[0081] The negative pressure chamber 233 is connected to the dust collecting chamber 21 in the base 20, and the driving member 231 is movably arranged in the pressure area of ​​the negative pressure chamber 233, converting the pneumatic energy into linear displacement or equivalent displacement by means of the pressure difference. Structurally, the negative pressure chamber 233 is preferably arranged near the main suction area of ​​the dust collecting chamber 21, and the negative pressure formed by the negative pressure mechanism 24 in the dust collecting chamber 21 is transmitted to the negative pressure chamber 233 through the connecting channel. The driving member 231 is movably arranged in the negative pressure chamber 233 and can be set as a piston or other slidable mechanical element. Its structural design can slide in response to the suction force of the negative pressure. The driving member 231 can be connected to the unlocking member 232 by a hinge or other mechanical connection method, and the movement driven by the negative pressure is transmitted to the unlocking member 232 to trigger the unlocking action. As an actuator, the unlocking member 232 can press or push the locking member 13 of the dust cup 10 to switch it from the locked position to the unlocked position, releasing the locked state of the cover 12.

[0082] For details, please refer to Figure 5 and Figure 6 As shown, the cover opening mechanism 23 also includes an installation chamber 234 and a bottom cover 235. The driving member 231 is arranged in the installation chamber 234 and slides with the side wall of the installation chamber 234. A sealing ring is provided between the side wall of the installation chamber 234 and the driving member 231, and the space between the driving member 231 and the bottom cover 235 constitutes a negative pressure chamber 233.

[0083] Mounting chamber 234 serves as a rigid load-bearing and guiding body, its inner wall machined into a sliding surface that matches driver 231, ensuring linear reciprocating motion of driver 231 along a predetermined axis. A sealing ring, preferably an O-ring or a combination seal with a dust lip, is positioned between the periphery of driver 231 and the sidewall of mounting chamber 234. The sealing ring can be made of an elastic material (such as rubber or silicone) and fits tightly into the gap between the periphery of driver 231 and the sidewall of mounting chamber 234, forming an airtight seal. This prevents leakage of negative pressure within negative pressure chamber 233 and ensures that the negative pressure can fully act on driver 231 to generate sufficient driving force.

[0084] Bottom cover 235 is sealed and fixed to mounting chamber 234, forming an independent negative pressure chamber 233 with the end surface of driver 231. Bottom cover 235 serves a dual function: first, it acts as an aerodynamic boundary, using its rigidity and sealing structure to withstand pressure differential loads and maintain the stability of the chamber's shape, preventing elastic deformation under negative pressure that could affect travel. Second, it serves as an interface and assembly platform, integrating a negative pressure tap to provide pressure differential input to negative pressure chamber 233.

[0085] For further information, please refer to Figure 1 and Figure 5 As shown, the bottom cover 235 is provided with a first interface 236 connected to the negative pressure chamber 233, and the base 20 is provided with a second interface 25 connected to the dust collecting chamber 21. The first interface 236 is connected to the second interface 25, and the second interface 25 is arranged adjacent to the air intake of the negative pressure mechanism 24.

[0086] The first interface 236 provided on the bottom cover 235 serves as the air outlet of the negative pressure chamber 233; the second interface 25 provided on the base 20 serves as the connecting end between the dust collecting chamber 21 and the external branch. The first interface 236 is connected to the second interface 25 through an airtight and reliable connecting pipe, preferably a flexible hose, and a detachable seal is achieved at both ends by means of a clamp or a screw. The first interface 236 is directly connected to the negative pressure chamber 233 by a rigid wall; the first interface 236 can be provided on the bottom cover 235 and designed as a hole-shaped or tubular structure, directly connected to the interior of the negative pressure chamber 233. The function of the first interface 236 is to serve as the negative pressure input port of the negative pressure chamber 233, receiving the negative pressure transmitted from the dust collecting chamber 21, so that the driving member 231 can move under the action of the negative pressure.

[0087] The second interface 25 is preferably arranged near the air intake of the negative pressure mechanism 24, so that the air source point of the negative pressure chamber 233 is close to the system negative pressure extreme area, thereby obtaining a higher effective pressure difference under the same fan operating conditions, ensuring that the negative pressure acting on the driving member 231 is sufficient.

[0088] For details, please refer to Figure 3 and Figure 4 As shown, a first reset member 237 is provided between the bottom cover 235 and the driving member 231. The first reset member 237 is used to enable the driving member 231 to drive the unlocking member 232 to reset when the negative pressure in the negative pressure chamber 233 is lower than the critical value, so as to cancel the unlocking operation of the locking member 13.

[0089] The first restoring member 237 can provide a restoring thrust for the driving member 231 when the pneumatic driving force in the negative pressure chamber 233 disappears or is lower than a critical value. Figure 6The first return member 237 can be a linear compression spring, a torsion spring 124, or a magnetic repulsion structure (e.g., repelling magnets). It is installed between the parallel surfaces of the driver 231 and the bottom cover 235, ensuring that the force applied is consistent with the displacement direction of the driver 231.

[0090] The bottom cover 235 provides a mounting base for the first reset member 237, while the driver 231 serves as the actuator at the other end of the first reset member 237, maintaining a continuous mechanical coupling between the two through the first reset member 237. The first reset member 237 maintains a certain potential energy in a static state to ensure that a driving force is always present before the driver 231 returns to its initial position, thereby preventing the driver 231 from becoming stuck or unable to fully reset. When the negative pressure mechanism 24 is activated and a sufficient pressure differential is established within the negative pressure chamber 233, the driving force generated by the negative pressure is greater than the reverse thrust provided by the first reset member 237. The driver 231 overcomes the reset force and moves in the unlocking direction, driving the unlocking member 232 to unlock the locking member 13. When the negative pressure gradually decays and drops below a critical threshold, the reverse force of the reset member regains dominance, pushing the driver 231 back, and the unlocking member 232 resets, canceling its effect on the locking member 13 and allowing the locking member 13 to return to its locked position under the action of the second reset member 134.

[0091] In an exemplary embodiment, please refer to Figure 5 、 Figure 6 and Figure 10 As shown, the unlocking member 232 includes a main body 2321 and a pivot portion 2322 arranged in the middle area of ​​the main body 2321, and the main body 2321 can rotate around the pivot portion 2322; one end of the main body 2321 is hinged to the driving member 231, and the other end is provided with an unlocking portion 2323 for operating the locking member 13; after the dust cup 10 is docked with the dust collecting base station 2, the driving member 231 moves under the action of negative pressure and drives the main body 2321 to rotate around the pivot portion 2322, so that the unlocking portion 2323 moves toward the locking member 13 to press the operating locking member 13.

[0092] The unlocking member 232 adopts a toggle arm configuration centered on the pivot portion 2322. The main body 2321 rotates around the central pivot portion 2322 in the installation chamber 234, forming an angular displacement structure that converts the linear displacement of the driving member 231 into pressing / pushing the locking member 13. The pivot portion 2322 is a pivot 238 hole or a similar structure, allowing the main body 2321 to rotate with the pivot portion 2322 as a fulcrum. One end of the main body 2321 is connected to the driving member 231 through a hinge structure, and can respond to the sliding of the driving member 231 and convert it into its own rotational movement. The unlocking portion 2323 at the other end of the main body 2321 is a protrusion or a similar pressing structure, corresponding to the pressing portion 133 of the locking member 13 of the dust cup 10.

[0093] After the dust cup 10 is docked with the dust collecting base station 2, the driving member 231 outputs displacement along its own guide axis under the action of negative pressure (or equivalent electromechanical drive), and inputs driving force to the unlocking member 232 through the hinge point, so that the main body 2321 produces angular displacement around the pivot part 2322, so that the unlocking part 2323 obtains sufficient displacement and pressing torque, thereby switching the locking member 13 from the locked position to the unlocked position.

[0094] For details, please refer to Figure 6 and Figure 10 As shown, the unlocking member 232 is arranged in the installation chamber 234 and is located on the side of the driving member 231 away from the negative pressure chamber 233. The side wall of the installation chamber 234 is provided with a pivot 238, and the pivot part 2322 is pivoted to the pivot 238; the unlocking member 232 is provided with a hinge hole 2324, and the driving member 231 is provided with a hinge shaft 2311, and the hinge shaft 2311 is hinged to the hinge hole 2324. The size of the hinge hole 2324 is larger than the size of the hinge shaft 2311, so as to provide a motion compensation space when the driving member 231 performs a linear motion and the unlocking member 232 performs a pivotal motion.

[0095] Unlocking member 232 is positioned within mounting chamber 234, on the side of driving member 231 facing away from negative pressure chamber 233, structurally separating the drive chain from the pressure chamber. A pivot 238 is provided on the sidewall of mounting chamber 234. This pivot 238 and pivot portion 2322 of unlocking member 232 form a pivoting structure, allowing unlocking member 232 to swing angularly along a predetermined plane when subjected to force. This predictable trajectory of the unlocking end ensures that the pressing path aligns with locking member 13.

[0096] At the hinged joint between the driver 231 and the unlocking member 232, the unlocking member 232 is provided with a hinge hole 2324, and the driver 231 is provided with a hinge shaft 2311, forming a hinged connection between the two. The hinge hole 2324 is larger than the hinge shaft 2311, creating a controlled clearance fit that provides the necessary motion compensation between the linear drive and the pivot output. Because the driver 231 slides linearly along the guide axis while the unlocking member 232 pivots relative to the pivot shaft 238, the instantaneous velocity directions and trajectory curvatures of the two are inconsistent. A tight or overly tight fit of equal dimensions would inevitably result in lateral extrusion and constraint conflicts. The dimensional difference provides the necessary space for motion compensation, avoiding jamming or mechanical loss caused by differences in motion trajectory.

[0097] In an exemplary embodiment, please refer to Figure 8 As shown, the base 20 is provided with a sensor 26 and a control module, and the control module is electrically connected to the sensor 26 and the negative pressure mechanism 24 respectively; the sensor 26 is configured to output a sensing signal in response to the docking of the dust cup 10 and the dust collection base station 2, and the control module triggers the negative pressure mechanism 24 to start in response to the sensing signal to form negative pressure.

[0098] The sensor 26 is preferably arranged in the guide / limiting area near the docking part 22 to obtain docking information when the dust cup 10 slides in and reaches a predetermined posture and depth; the sensor 26 can use photoelectric (such as reflective / transmitting infrared) or piezoelectric / mechanical (such as micro switch) devices according to structural conditions, and isolate it from the dust-laden airflow through a window cover, a transparent dustproof sheet or an elastic dustproof cover to reduce false triggering caused by dust deposition.

[0099] The control module serves as a control center and can be integrated into the base 20. It is implemented through a circuit board or a microcontroller, and is electrically connected to the sensor 26 and the negative pressure mechanism 24. It can analyze the sensing signal of the sensor 26 and generate control instructions to trigger the negative pressure mechanism 24 to start.

[0100] For details, please refer to Figures 1 to 4 As shown, the base 20 is provided with a cover closing mechanism 27 connected to the control module. The control module is configured to control the cover closing mechanism 27 to push the cover body 12 back from the open state to the closed state after the negative pressure mechanism 24 stops.

[0101] The base 20 integrates a lid closing mechanism 27 electrically connected to the control module. This mechanism reliably pushes the lid 12 back from the open position to the closed position after dust collection and negative pressure dissipation. The lid closing mechanism 27 is preferably located inside or adjacent to the dust collection port 221. The control module only issues an execution command to the lid closing mechanism 27 after detecting that the negative pressure mechanism 24 has stopped. This prevents dust recirculation or impact suction caused by premature lid closing in the presence of strong suction.

[0102] The actuator end of the lid closing mechanism 27 contacts the force-bearing area of ​​the lid body 12 along a predetermined trajectory, converting displacement into a rotational torque at the hinge through surface pressure or linear pressure, thereby switching the lid body 12 from the open state to the closed state. As the lid body 12 closes, the free end 122 of the lid body 12 and the locking member 13 are re-engaged and self-retained.

[0103] Further, please refer to Figure 8 and Figure 11 As shown, the docking portion 22 of the base 20 is provided with a dust collecting port 221 connected to the dust collecting chamber 21, and is configured to open the cover body 12 toward the inner side of the dust collecting port 221 after the cover opening mechanism 23 performs the unlocking operation, so as to connect the dust discharge port 111 of the dust cup 10 with the dust collecting chamber 21; the cover closing mechanism 27 includes a servo 271 and a push plate 272 driven by the output shaft of the servo 271, and the push plate 272 is arranged on the inner side of the dust collecting port 221, and can be rotated under the drive of the servo 271 to push the cover body 12 to close.

[0104] The opening surface of the dust collecting port 221 and the dust exhaust port 111 on the side wall of the dust cup 10 are arranged face to face at the docking end position. When the cover opening mechanism 23 completes unlocking the cover body 12, the cover body 12 opens to the inside of the dust collecting port 221 with its hinge axis as the rotation axis, and a connecting channel is immediately established between the dust exhaust port 111 and the dust collecting chamber 21.

[0105] The lid closing mechanism 27 uses a servo 271 as its actuating source. The output shaft of the servo 271 is fixedly connected to a push plate 272, which is positioned inside the dust collection port 221 and rotates along a predetermined trajectory. The force-bearing edge of the push plate 272 engages tangentially with the outer surface of the lid 12 (or its force-bearing flange). During closing, the angular displacement of the servo 271 is converted into a rotational torque on the lid 12 through surface or linear pressure, allowing the lid 12 to smoothly return to its closed position. After the lid 12 is closed, the push plate 272, driven by the servo 271, returns to its original position, leaving the dust collection port 221 clear and unobstructed, preventing interference with the next lid opening.

[0106] To sum up, the dust collection base station and cleaning system provided by the present invention trigger the cover opening mechanism through docking. After the dust cup completes docking, the cover opening mechanism is automatically triggered in response to the docking event, and performs the unlocking operation of the cover body, so that the dust discharge port of the dust cup is connected with the dust collection chamber, avoiding the tediousness of traditional manual cover opening and the risk of dust leakage.

[0107] It will be apparent to those skilled in the art that the present disclosure is not limited to the details of the exemplary embodiments described above and that the present disclosure can be implemented in other specific forms without departing from the spirit or essential characteristics of the present disclosure.
