Detailed Implementation

[0037] 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.

However, if the description of the component positions changes, then these representations are considered to change accordingly.

[0040] Vacuum cleaners, as widely used cleaning devices, rely heavily on their dust cups as the core component for collecting dust, hair, and lint. During their research and analysis of existing dust cup structures, the inventors discovered that users still face numerous inconveniences when emptying the dust cup, especially with tangled debris such as hair and lint often adhering to the filter or accumulating at the bottom of the dust cup, making them difficult to remove by simple emptying. This problem is particularly pronounced in pet-owning households, high-fiber environments, or high-frequency usage scenarios, severely impacting cleaning efficiency and user experience.

[0041] The root cause of these problems lies in the fact that most existing structures rely on manual disassembly and cleaning by users, lacking an internal coordination mechanism to achieve dust cup cleaning or coordinated cleaning. Furthermore, the adhesion of foreign matter to the filter surface, the independent operation of opening the cover, and the lack of auxiliary thrust in the dust discharge process are all key factors contributing to the difficulty in thoroughly removing debris. In addition, conventional dust cup structures generally treat filter cleaning and debris discharge as two independent steps. After cleaning the filter, users still need to separately perform operations such as opening the cover and emptying the dust to complete the debris discharge, making the process cumbersome.

[0042] To address this issue, this disclosure proposes a design concept for a dust collection device. The core of this concept lies in establishing an interconnected control logic within the dust cup, enabling the sequential and coordinated completion of filter cleaning, dust cup lid unlocking, and waste discharge with a single user operation. The device constructs a set of interoperable functional components to clean the filter structure. During the cleaning process, the dust cup opens; simultaneously, during dust discharge, internal thrust assists in waste release, thus achieving coordinated cleaning actions. This design concept departs from the traditional cleaning model that relies on decentralized operations, integrating filter cleaning and waste discharge into a continuous mechanical process. Users can trigger the entire cleaning process with simple operations (such as pushing or pressing), without the need for additional tools or complex steps.

[0043] Please refer to Figures 1 to 6As shown, a dust collection device in one embodiment of this disclosure includes a dust cup assembly 1, a filter assembly 2, a dust scraping assembly 3, an unlocking component 4, and a pop-out component 5.

[0044] The dust cup assembly 1 includes a cup body 11, a cover 12, and a locking switch 13. The cup body 11 has a receiving space 111 and a dust discharge port 112 communicating with the receiving space 111. The cover 12 is closably disposed on the dust discharge port 112. The locking switch 13 is operably disposed on the cup body 11 for locking the cover 12 when closed. The filter assembly 2 includes a filter screen 21 disposed within the receiving space 111. The dust scraper assembly 3 includes a dust scraper 31 movably disposed on the filter screen 21 and a drive member 32 for driving the dust scraper 31 to move along the filter screen 21. The unlocking member 4 is disposed corresponding to the locking switch 13 and can be driven by the drive member 32 to release the locking switch 13 from locking the cover 12. The pop-out assembly 5 includes a pop-out member 51 disposed within the receiving space 111 and a first elastic member 52. The pop-out member 51 is movably connected to the filter assembly 2, and the first elastic member 52 is connected to the pop-out member 51 and the filter assembly 2.

[0045] When the cover 12 is closed, the pop-out member 51 is pushed by the cover 12 so that the first elastic member 52 stores elastic potential energy; when the drive member 32 moves to the predetermined position, it can drive the unlocking member 4 to operate the locking switch 13 to release the lock on the cover 12, so that the first elastic member 52 releases elastic potential energy and drives the pop-out member 51 to pop out toward the dust discharge port 112.

[0046] The dust cup assembly 1 serves as the basic structure for waste collection and sealing. Its cup body 11 has a receiving space 111 for storing dust, hair, and other debris sucked in by the vacuum cleaner, and a dust outlet 112 communicating with the receiving space 111 for easy waste discharge. The cover 12 is closable and connected to the dust outlet 112 via a hinge or other movable connection, ensuring the receiving space 111 is sealed during vacuum cleaner operation to prevent dust leakage. A locking switch 13 is mounted on the cup body 11 and operably locks the closed cover 12, ensuring it remains securely closed during vacuuming, while allowing the user to unlock it to discharge debris when needed.

[0047] The filter assembly 2, located within the housing space 111, is the main component for achieving air-dust separation. Its filter screen 21 is used to trap large particles, hair, and other debris carried in the air, achieving primary dust-air separation of the dust-laden airflow. However, during long-term use, a large amount of hair and dust easily adheres to the surface of the filter screen 21, leading to increased airflow resistance and affecting suction performance. Therefore, this device is equipped with a dust scraper assembly 3 to clean the deposits on the filter screen 21.

[0048] The dust removal assembly 3 includes a dust removal component 31 and a driving component 32. The dust removal component 31 is fitted to the filter screen 21 and can move along the surface of the filter screen 21 under the action of the driving component 32, thereby removing attached hair, dust, etc. The driving component 32 can adopt a sliding structure, which moves through user operation and transmits linear power to the dust removal component 31, causing it to perform circumferential scraping along the outer periphery of the filter screen 21. To improve cleaning coverage, the dust removal component 31 can be designed as a ring structure, surrounding the outer periphery of the filter screen 21, and making axial reciprocating motion under the drive of the driving component 32, thereby achieving full coverage of the clean surface of the filter screen 21.

[0049] At the endpoint of the scraper 31's movement, i.e., after completing one circumference of the filter screen 21, the drive component 32 reaches its predetermined position, triggering the linkage unlocking mechanism. This unlocking component 4 corresponds to the locking switch 13 and can rotate or pop out under the push of the drive component 32, unlocking the previously locked cover 12. This linkage design eliminates the need for the user to separately operate the cover opening button, achieving integrated operation and enhancing the user experience. Simultaneously, the completion of the unlocking action also creates conditions for subsequent waste discharge.

[0050] To further address the problem of difficult removal of debris (especially hair clumps) from the bottom of the dust cup, this device also introduces a pop-out component 5. This component 5 includes a pop-out member 51 and a first elastic element 52, located inside the receiving space 111 and movably connected to the filter component 2. Specifically, when the cover 12 is closed, the pop-out member 51 is pressed against the cover 12, causing the first elastic element 52 to be compressed and store elastic potential energy. When the unlocking mechanism is triggered and the cover 12 is unlocked, the first elastic element 52 releases its stored energy, causing the pop-out member 51 to quickly pop out towards the dust outlet 112, thereby actively pushing out the debris from the bottom of the dust cup. This design assists in the removal of debris from the dust cup, especially effectively removing highly adhesive debris (such as hair and lint). The pop-out component 51 can be designed as a cylindrical structure fitted around the outer periphery of the filter assembly 2. Its top outer periphery can extend out a structural part for pushing the waste. With the help of spring force, it moves towards the dust discharge port 112 at the moment of opening, forming a pushing force to discharge the internal waste to the outside of the cup body 11.

[0051] In one exemplary embodiment, please refer to Figure 1 and Figure 4 As shown, the filter assembly 2 includes a cover 22, a filter screen 21 disposed on the outer periphery of the cover 22, a pop-out member 51 slidably connected to the cover 22, and a first elastic member 52 connected between the pop-out member 51 and the cover 22.

[0052] The cover 22 serves as the skeleton of the internal structure, providing stable support for the filter 21 and ensuring that the filter 21 does not deform or misalign during airflow. The filter 21 is fixed to the outside of the cover 22 by covering or sleeve, forming an annular filter surface, which traps large particles such as hair when they enter the dust cup.

[0053] The pop-out component 51 and the cover 22 are slidably connected, and the pop-out component 51 can move relative to the cover 22 along the axial direction. This sliding fit can be achieved by setting a guide structure, which on the one hand ensures the stability and directionality of the movement of the pop-out component 51 and avoids deflection or jamming, and on the other hand facilitates the transmission of elastic force under the action of the elastic element to achieve rapid rebound movement.

[0054] The first elastic element 52 is disposed between the pop-out member 51 and the cover 22, and serves to store energy when the pop-out member 51 is compressed and to rebound when released. When the cover 12 is closed, the cover 12 presses the pop-out member 51 toward the cover 22, compressing the elastic element to store potential energy; when the device is unlocked and the cover 12 is opened, the elastic element releases energy, pushing the pop-out member 51 to slide axially along the cover 22, thereby causing the pusher at its top to pop out toward the dust discharge port 112, actively pushing out the residual garbage.

[0055] Specifically, please refer to Figure 1 , Figure 4 , Figure 10 and Figure 11 As shown, the cover 22 is provided with a sliding hole 23 extending along its axial direction, and the pop-out member 51 is provided with a sliding rod 511 that cooperates with the sliding hole 23. The sliding rod 511 is slidably disposed in the sliding hole 23, and the top end of the sliding rod 511 is provided with a flange 512, the size of which is larger than the size of the sliding hole 23.

[0056] To ensure that the pop-out component 51 moves smoothly in a predetermined direction when releasing its elastic potential energy, and to prevent deviation, jamming, or structural detachment, a sliding guide structure is provided. The cover 22 and the pop-out component 51 are guided and limited by the cooperation of sliding holes 23 and sliding rods 511. Specifically, the cover 22 can be provided with multiple sliding holes 23 extending along its axial direction. These sliding holes 23 can be distributed in the drainage channel between the filter screen 21 and the cover 22 to form multiple axial guide channels. Correspondingly, the pop-out component 51 is provided with sliding rods 511 corresponding to the sliding holes 23 one-to-one. The sliding rods 511 are slidably inserted into the sliding holes 23, allowing the pop-out component 51 to move along the axial direction of the cover 22 under the push of the elastic element.

[0057] To prevent the slide rod 511 from detaching from the slide hole 23 due to elastic force during the ejection of the ejector component 51, a radially protruding flange 512 structure is provided at the top of the slide rod 511. The outer diameter of the flange 512 is larger than the diameter of the slide hole 23, so that when the ejector component 51 is ejected, the flange 512 can effectively abut against the top wall 231 of the slide hole 23, forming a limiting stop structure to prevent the slide rod 511 from being completely pushed out of the slide hole 23.

[0058] Further, please refer to Figure 4 As shown, the first elastic member 52 is a compression spring sleeved on the outer periphery of the slide rod 511, and the pop-out member 51 is provided with a limiting groove 513 surrounding the outer periphery of the bottom end of the slide rod 511; one end of the first elastic member 52 abuts against the bottom wall 514 of the limiting groove 513, and the other end abuts against the top wall 231 of the sliding hole 23.

[0059] To ensure that the pop-out component 51 can pop out quickly and stably toward the dust outlet 112 after unlocking, a compression spring is preferably used as the first elastic element 52. Specifically, the first elastic element 52 is preferably a compression spring that is wrapped around the outer periphery of the slide rod 511. This compression spring is located between the pop-out component 51 and the cover 22 and is mainly used to store and release elastic potential energy to drive the pop-out action of the pop-out component 51.

[0060] To ensure reliable positioning and stable force application of the compression spring, a circumferential limiting groove 513 is provided on the outer periphery of the bottom end of the slide rod 511 on the pop-out component 51. This limiting groove 513 has a bottom wall 514 surface, which serves as a force-bearing support surface for one end of the compression spring, preventing positional displacement or axial movement of the spring under compression. The other end of the compression spring abuts against the inner side of the top wall 231 of the sliding hole 23 in the cover 22. This top wall 231 serves as a fixed reference for the other end, ensuring that the spring is under compression when the pop-out component 51 is compressed, and can quickly extend along the axial direction of the slide rod 511 after unlocking, pushing the pop-out component 51 towards the dust discharge port 112.

[0061] In one exemplary embodiment, please refer to Figure 1 and Figure 10 As shown, the cover 22 includes a mounting frame 221, a dust collection cylinder 222, and a guide pipe 223. The dust collection cylinder 222 has a dust collection chamber 224 that extends axially through its top and bottom. The guide pipe 223 is located at the top of the dust collection cylinder 222 and communicates with the top opening of the dust collection cylinder 222. The mounting frame 221 is located around the guide pipe 223. The filter screen 21 is surrounded on the mounting frame 221. The bottom opening of the dust collection cylinder 222 is closed by the cover 12 when the cover 12 is closed.

[0062] The dust collection cylinder 222, as the main structure of the cover 22, is a hollow cylindrical shape. Inside, a dust collection chamber 224 is formed that runs through the top and bottom. This dust collection chamber 224 can be used to collect the waste separated by secondary dust-gas separation. The bottom of the dust collection cylinder 222 has an opening. When the cover 12 is closed, the bottom opening and the cover 12 are sealed together to form an effective dust-gas isolation structure, preventing airflow leakage or dust leakage during the dust collection process.

[0063] The top of the dust collection cylinder 222 is equipped with a guide pipe 223, which connects to the top opening of the dust collection cylinder 222. Its main function is to connect with the cyclone separator used to achieve secondary dust-gas separation, and to guide the dust separated in the dust-laden airflow from the outlet of the cyclone separator into the dust collection chamber 224. The guide pipe 223 can be designed as a straight cylinder or a tapered shape, and can be optimized according to the overall airflow path to improve airflow stability, reduce turbulence, and enhance dust settling effect.

[0064] The mounting bracket 221 is located on the outer periphery of the guide tube 223 and serves as a support for the filter screen 21. On one hand, it provides a fixed circumferential boundary for the filter screen 21, allowing it to tightly cover its outer side, ensuring the integrity of the filter surface and preventing displacement or loosening. On the other hand, the arrangement between the mounting bracket 221 and the guide tube 223 provides a basis for forming an airflow channel between the filter screen 21 and the guide tube, while also facilitating the removal, installation, and replacement of the filter screen 21.

[0065] Specifically, please refer to Figure 1 and Figure 11 As shown, the pop-out component 51 includes a cylindrical portion 515 adapted to the dust collection cylinder 222. The cylindrical portion 515 is sleeved on the outer periphery of the dust collection cylinder 222, and the top outer periphery of the cylindrical portion 515 extends to form an extension portion 516 for pushing the waste. The cylindrical portion 515 is a hollow cylindrical structure, and its inner diameter matches the outer diameter of the dust collection cylinder 222, and it is installed on the outer periphery of the dust collection cylinder 222 in a sleeved manner.

[0066] To achieve effective waste pushing, a protruding extension 516 extends from the top outer periphery of the cylinder 515. Structurally, this extension 516 can be annular or tongue-shaped, extending outward along the radial or axial direction of the cylinder. It is designed to be larger than the diameter of the main body of the cylinder. Its main function is to contact the waste inside the cup 11 when the ejector component 51 is ejected, thereby pushing hair, debris, and other debris accumulated below the filter screen 21 or at the bottom of the cup 11 toward the dust discharge port 112.

[0067] Further, please refer to Figure 1 and Figure 2As shown, the cover 12 is provided with a boss 121 protruding towards the bottom opening of the dust collection cylinder 222. A sealing gasket 122 is provided on the top of the boss 121. When the cover 12 is closed, the bottom ends of the dust collection cylinder 222 and the cylinder part 515 abut against the sealing gasket 122 to close the bottom opening of the dust collection cylinder 222.

[0068] The main function of the cover 12 is to close the receiving space 111 when the vacuum cleaner is running and to open it to discharge debris during cleaning. On the inner side of the cover 12, corresponding to the position of the bottom opening of the dust collection cylinder 222, there is a protrusion 121 protruding towards the dust collection cylinder 222. The protrusion 121 can be a cylindrical structure, and its shape and size are adapted to the bottom opening of the dust collection cylinder 222 to ensure that the cover 12 can completely cover the opening when closed.

[0069] To further improve sealing reliability, a sealing gasket 122 is provided on the top of the boss 121. This gasket is usually made of flexible elastic material (such as silicone, rubber, etc.) and has a certain compression deformation capacity. It can generate a pre-compression state when the cover 12 is closed to fill the tiny gaps that may exist between the boss 121 and the dust collection cylinder 222 and the bottom end of the cylinder part 515 of the pop-out component 51, thereby achieving efficient air and dust isolation and preventing dust and gas leakage during the dust collection process.

[0070] In terms of structural fit, when the cover 12 is closed, the bottom end of the dust collection cylinder 222 and the bottom end of the cylinder part 515 sleeved around its periphery will press down together and abut against the top of the sealing gasket 122 to form a closed surface. Since the cylinder part 515 and the dust collection cylinder 222 adopt a sleeved sliding relationship, their bottoms form a coplanar structure, which can press against the sealing gasket 122 simultaneously after closing, achieving double pressing and sealing.

[0071] In one exemplary embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the outer wall of the cup body 11 is provided with a housing 14, and the unlocking member 4 is provided inside the housing 14. The unlocking member 4 has a tongue 41. The housing 14 is provided with a through hole 141 at the corresponding position of the locking switch 13, and the tongue 41 passes through the through hole 141. When the unlocking member 4 is driven by the driving member 32, the tongue 41 can pass through the through hole 141 to press the locking switch 13 to release the lock on the cover 12.

[0072] The housing 14 is an additional protective and support structure, which may be made of a sturdy material and covers part of the outer surface of the cup body 11. The design of the housing 14 not only provides the user with an external structure that is easy to grip, but also provides installation space for the unlocking component 4 and the driving component 32.

[0073] The tongue 41 of the unlocking component 4 is structurally oriented towards the outside of the housing 14 and corresponds to the position of the locking switch 13. In order to realize the action transmission between the tongue 41 and the external locking switch 13, the housing 14 is provided with a through hole 141 at the position corresponding to the locking switch 13. The size of the through hole 141 is adapted to the tongue 41, allowing the tongue 41 to pass through the through hole 141 and make contact with the locking switch 13 during structural action.

[0074] When the driving component 32 is pushed and slid to the predetermined position by the user, it will drive the connected transmission structure to act on the unlocking component 4, pushing the unlocking component 4 to rotate or displace, so that the tongue 41 extends out along the through hole 141 and directly presses the locking switch 13 located in the cup body 11. This pressing action switches the locking switch 13 from the locked position to the unlocked position, thereby releasing the locking state between the cover 12 and the cup body 11. In this process, the user does not need to operate the locking button separately, but only needs to complete the pushing operation of the driving component 32 once to complete multiple functional steps such as dust scraping, unlocking, and popping out in sequence, which improves the integration of the dust collection device and the ease of use.

[0075] Specifically, please refer to Figure 7 , Figure 8 and Figure 9 As shown, the driving component 32 is located inside the housing 14. The driving component 32 includes a guide rod 321, a push rod 322, and a push button 323 connected to the push rod 322. The guide rod 321 is fixed to the housing 14 along the axial direction of the cup body 11. The push rod 322 is slidably connected to the guide rod 321. The scraper 31 is connected to the push rod 322. The push button 323 is used to push the push rod 322 to slide along the guide rod 321 to drive the scraper 31 to move.

[0076] The guide rod 321 serves as the transmission reference component of the entire drive assembly. It is arranged along the axial direction of the cup body 11 and fixedly installed inside the housing 14, providing guidance, constraint, and support for the sliding of the push rod 322. The axial arrangement of the guide rod 321 is adapted to the annular or columnar structure of the filter screen 21, ensuring that the movement path of the scraper 31 corresponds to the surface of the filter screen 21, thereby achieving higher adhesion and coverage during the scraping process. The guide rod 321 can be a slender rod, and the material selection preferably possesses good rigidity and wear resistance to ensure guiding accuracy and structural strength.

[0077] The push rod 322 is slidably connected to the guide rod 321 and can reciprocate along the axial direction of the guide rod 321. It connects the scraper component 31 and the push button 323. The sliding design of the push rod 322 allows the user to transmit force to the internal scraper component 31 through the linear operation of the external push button 323, thereby driving the scraper component 31 to move along the surface of the filter screen 21 to remove the adsorbed material. The connection between the push rod 322 and the scraper component 31 can be achieved through a snap-fit, threaded, or grooved structure to ensure efficient and stable force transmission during operation, preventing it from easily falling off or becoming misaligned.

[0078] The push button 323, serving as the direct interaction component between the user and the drive unit 32, is located outside the housing 14 or in an area easily pressed, and is connected to the push rod 322 via a connecting structure. When the user pushes the push button 323, the push rod 322 slides axially under the constraint of the guide rod 321, thereby driving the scraper 31 to move along a set path on the outer periphery of the filter screen 21.

[0079] Further, please refer to Figure 9 As shown, the housing 14 is provided with a shaft hole 142, and the unlocking member 4 is provided with a pivot 42, which is pivotally connected to the shaft hole 142; the end of the push rod 322 is provided with a first guide surface 324, and the unlocking member 4 is provided with a second guide surface 43 that matches the first guide surface 324. When the driving member 32 moves to the predetermined position, the first guide surface 324 pushes against the second guide surface 43, causing the tongue 41 of the unlocking member 4 to rotate around the pivot 42 and pass through the through hole 141 to press the locking switch 13.

[0080] In this embodiment, to achieve linkage control between user operation and the unlocking action of the cover 12, a mechanical transmission system based on a rotation mechanism is set up, in which the housing 14, the unlocking component 4, the push rod 322 and its guiding structure constitute a complete drive path. Specifically, the housing 14 is provided with a shaft hole 142 for supporting the unlocking component 4, which can be formed on the side wall or internal frame of the housing 14. The unlocking component 4 is provided with a pivot 42, one or both ends of which are embedded in the shaft hole 142 to form a pivotal connection, allowing the unlocking component 4 to rotate around the pivot 42 at a certain angle.

[0081] To further realize the transmission relationship between the driving component 32 and the unlocking component 4, the end of the push rod 322 is designed with a first guide surface 324. The first guide surface 324 can be an inclined or curved structure, used to contact the second guide surface 43 of the unlocking component 4 when the push rod 322 slides along the guide rod 321 to a predetermined end position. The unlocking component 4 is correspondingly provided with a second guide surface 43 that matches the shape of the first guide surface 324. The two are designed in terms of structural shape and relative position to ensure that a smooth and stable sliding path can be formed during the contact process.

[0082] When the user pushes the push button 323 to slide the push rod 322 to the set position, the first guide surface 324 gradually pushes the second guide surface 43. Since the unlocking member 4 is constrained by the pivot 42, it rotates around the pivot 42 under the action of the pushing force, causing its tongue 41 to gradually protrude along the through hole 141 of the housing 14. During the rotation, the end of the tongue 41 gradually approaches and finally presses the locking switch 13, releasing the locking mechanism from the locked state to the unlocked state, thereby unlocking the cover 12 and providing conditions for the subsequent release of the ejector member 51.

[0083] Furthermore, please refer to Figure 5 and Figure 6 As shown, a second elastic member 44 is provided between the housing 14 and the unlocking member 4. The second elastic member 44 is used to drive the tongue 41 of the unlocking member 4 to rotate away from the locking switch 13. A reset member 325 is provided between the push rod 322 and the housing 14. The reset member 325 is used to reset the push rod 322 after the pushing force on the push rod 322 is removed.

[0084] To ensure that the unlocking mechanism and the drive mechanism can be reset to their initial positions in a timely and accurate manner after the operation is completed, thereby achieving reliability and consistency of repeated work, two sets of structures are set up: the second elastic element 44 and the reset element 325, which correspond to the reset control of the unlocking element 4 and the push rod 322, respectively.

[0085] Specifically, the second elastic element 44 is disposed between the housing 14 and the unlocking element 4, and is used to apply a continuous elastic force to the unlocking element 4, so that its tongue 41 always rotates away from the locking switch 13 when not under force. The second elastic element 44 can be a torsion spring or a compression spring, one end of which is fixed in a limiting post or mounting hole inside the housing 14, and the other end is connected to the elastic arm or a specific spring hook point of the unlocking element 4. With this arrangement, when the push rod 322 pushes the guide surface to rotate the unlocking element 4 around the pivot 42, and the tongue 41 passes through the through hole 141 and presses the locking switch 13, the second elastic element 44 is in a compressed or torsional state; once the push force is removed, the second elastic element 44 releases its stored energy, which can drive the unlocking element 4 to rotate in the opposite direction, so that the tongue 41 quickly retracts into the housing 14, thereby avoiding accidental contact or structural interference caused by the tongue 41 being exposed for a long time.

[0086] The reset element 325 is located between the push rod 322 and the housing 14. Its main function is to provide a return force to the push rod 322 after the user completes the pushing action, causing it to automatically slide back to its original position from the pushing position, ready for the next driving operation. The reset element 325 can be a spring, a sheet spring, or other elastic element, with one end fixed to the inner wall of the housing 14 and the other end abutting against the end of the push rod 322 or its sliding base. During the pushing process, the reset element 325 is compressed; after the pushing force is released, the elastic force pushes the push rod 322 back to its original position along the guide rod 321. This structure not only ensures the return of the push rod 322 after operation but also drives the scraper 31 back to its starting position.

[0087] In one exemplary embodiment, please refer to Figure 2 and Figure 3 As shown, the cover 12 includes a hinged end 123 and a free end 124. The hinged end 123 is hinged to the cup body 11, and the free end 124 is provided with a slot 125. The locking switch 13 includes a pressing part 131, a hook part 132, and a hinge part 133 disposed between the pressing part 131 and the hook part 132. The hinge part 133 is hinged to the cup body 11. The locking switch 13 switches between the unlocked position and the locked position with the hinge part 133 as the fulcrum. When the cover 12 is closed, the hook part 132 engages with the slot 125 to lock the cover 12.

[0088] In this embodiment, in order to achieve reliable closure and convenient opening of the dust cup cover 12, a locking structure based on mechanical hinge and elastic buckle is designed. It consists of the cover 12 and the locking switch 13. The two are connected by a hinge end 123 and a free end 124 respectively and a snap-fit ​​structure that engages with each other to achieve opening and closing control.

[0089] Specifically, one end of the cover 12 is a hinged end 123, which can be connected to the cup body 11 through a pivoting structure or a hinge structure, allowing the cover 12 to rotate relative to the cup body 11 around the hinge axis, rotating from the open position to the closed state, forming a sealed structure for the dust cup. The other end is a free end 124, which has a slot 125 at its end for cooperating with the locking switch 13. The slot 125 can be formed in the flange 512 or reinforcing rib area of ​​the side wall of the cover 12, and has a shape adapted to the hook part 132 of the locking mechanism to provide a mechanical fitting surface.

[0090] Correspondingly, the locking switch 13 is designed as a lever-type latching mechanism with a press control function, comprising a pressing part 131, a hook part 132, and a hinge part 133 disposed between the two. The hinge part 133 is connected to the cup body 11 via a pivot or pin, allowing the entire locking switch 13 to swing within a certain angle range around the pivot point, thereby switching between the locked and unlocked positions. The pressing part 131 is located in a position accessible to the tongue 41 of the unlocking member 4, facing the through hole 141 area of ​​the housing 14; the hook part 132 is located at the end of the locking switch 13, and its shape is a hook-shaped structure protruding towards the cover 12, used to engage and fix with the slot 125 of the free end 124 of the cover 12.

[0091] During the closing process of the lid 12, the user rotates the lid 12 to the position where it is closed with the cup body 11. At this time, the slot 125 of the free end 124 of the lid 12 aligns and contacts the hook part 132. Subsequently, the hook part 132 springs into the slot 125 under its own elasticity or auxiliary elastic force, realizing mechanical engagement and thus stably locking the lid 12 in the closed state. This structure not only provides reliable locking force to prevent the lid 12 from being accidentally opened during use, but also achieves quick closing with minimal operating force. When it is necessary to open the lid 12, simply press the pressing part 131 to rotate the locking switch 13 around the hinge part 133, causing the hook part 132 to disengage from the slot 125, thereby releasing the lock and facilitating the opening of the lid 12 for garbage disposal.

[0092] Specifically, please refer to Figure 2 and Figure 3 As shown, a torsion spring 15 is provided between the hinge end 123 and the cup body 11. The torsion spring 15 is used to drive the lid 12 to rotate to open the dust outlet 112. A third elastic member 16 is provided between the pressing part 131 and the outer wall of the cup body 11. The third elastic member 16 is used to drive the locking switch 13 to remain in the locked position.

[0093] A torsion spring 15 is disposed between the hinge end 123 of the lid 12 and the cup body 11, with its two ends fixed to the structural reference points of the lid 12 and the cup body 11, respectively. When the lid 12 is closed, the torsion spring 15 stores energy through torsion. When the unlocking mechanism releases the lid 12, the torsion spring 15 releases its stored elastic potential energy, automatically driving the lid 12 to rotate around the hinge axis, thereby automatically opening the dust outlet 112. This structural design eliminates the need for manual lifting of the lid when cleaning up trash, improving cleaning efficiency, especially advantageous in scenarios requiring one-handed operation or where hand deprivation is a concern.

[0094] In conjunction with the automatic opening of the lid 12, a third elastic element 16 is used to keep the locking switch 13 in the closed state. This third elastic element 16 is located between the pressing part 131 of the locking switch 13 and the outer wall of the cup body 11, and typically employs a compression spring or elastic sheet structure. One end of it abuts against the inner side of the pressing part 131, and the other end is supported in the mounting position of the cup body 11. When the locking switch 13 is in the non-operating state, the third elastic element 16 remains in a pre-compressed state, continuously pushing the pressing part 131 outward, thereby keeping the locking switch 13 in the default locked position, i.e., the hook part 132 is stably embedded in the slot 125 of the free end 124 of the lid 12, ensuring that the lid 12 does not open accidentally during use. Only when an external force is applied to press the pressing part 131 will the third elastic element 16 be compressed, causing the hook part 132 to disengage from the slot 125 to complete the unlocking. After the operation is completed, the third elastic element 16 will automatically push the pressing part 131 back to its original position, so that the locking switch 13 returns to the locked position.

[0095] Further, please refer to Figure 1 As shown, a baffle 126 protrudes from the inner side of the cover 12. When the cover 12 is closed, the baffle 126 extends into the receiving space 111 to prevent the formation of swirling flow at the bottom of the receiving space 111. The baffle 126 can be an integral component of the cover 12 and is located on its inner side facing the receiving space 111.

[0096] With the cover 12 closed, the baffle 126 enters the dust cup along with the closing action of the cover 12, and is inserted vertically or at an angle into the receiving space 111. The baffle 126 is positioned near the dust outlet 112, placing it precisely in the area where dust and airflow may settle or form vortices. During vacuum cleaner operation, the negative pressure airflow generated by the high-speed operation of the motor creates a spiral or vortex flow inside the dust cup, especially at the bottom. When the airflow velocity decreases, local vortices are easily formed, causing settled dust, hair, and other debris to be disturbed and re-entrained into the airflow, thus affecting dust collection efficiency. The introduction of the baffle 126 can physically interrupt the vortex at the bottom, blocking the path for the airflow to form a circular motion at the bottom, thereby suppressing the formation of vortices.

[0097] This disclosure also provides a cleaning device, which includes a main body and the aforementioned dust collection device detachably mounted on the main body. The main body may integrate a motor, fan, power control, circuit system, and operating interface, etc., for providing suction drive, energy supply, and system operation control. The dust collection device serves as a functional module for dust collection and separation and is connected to the suction port of the main body.

[0098] In summary, the dust collection device and cleaning equipment provided in this disclosure can simultaneously trigger the unlocking mechanism after the user pushes the drive component to drive the scraper component to clean the filter screen, thereby releasing the locked state of the cover and making the cover openable. When the cover is openable, the pop-out component pops out towards the dust discharge port, actively pushing out the hair, lint, and other debris remaining in the dust cup, thus solving the problem of debris easily remaining in the dust cup and the cumbersome cleaning process.

[0099] 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.

[0100] 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.
