Detailed Implementation

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Handheld vacuum cleaners have become a common cleaning tool in homes and offices due to their portability and flexibility. However, the inventors' analysis revealed significant shortcomings in traditional handheld vacuum cleaners regarding dust removal and filter maintenance. They noted that users generally face problems such as inconvenient dust scraping, easy dust leakage, and cumbersome emptying procedures when cleaning the dust cup. Particularly during dust scraping, the lack of a supporting structure means the dust cup lid may remain open, increasing the risk of dust spreading into the environment and reducing the hygiene of the cleaning process. Furthermore, if users wish to empty the dust cup directly while scraping, they typically need to operate multiple additional parts, resulting in a poor user experience.

[0040] Based on the understanding of the above problems, this disclosure proposes a dust collection device that can be used in handheld vacuum cleaners. The core idea is to limit the stroke of the dust scraping operation so that the dust scraping process can be completed while the dust cup lid is closed, thereby avoiding the problem of the dust cup opening prematurely and dust escaping due to improper operation. Furthermore, by designing a switchable structural linkage mechanism, when it is necessary to complete dust scraping and emptying at the same time, the mechanism can remove the restriction on the unlocking component, so that the action of driving the dust scraping will trigger the unlocking and opening of the dust cup under certain conditions, thereby integrating the two originally relatively independent operations into a coordinated action.

[0041] Specifically, the device employs a controllable dust scraping mechanism, allowing the filter to be cleaned while the dust cup lid is closed, effectively preventing dust from escaping. Simultaneously, a switchable linkage unlocking mechanism allows users to remove the restriction on opening the lid as needed, enabling the dust scraping mechanism to trigger the lid opening while cleaning the filter, thus allowing the dust to be emptied.

[0042] Please refer to Figures 1 to 6 As shown, a dust collection device 10 in one embodiment of this disclosure includes a dust cup assembly 1, a filter assembly 2, a dust scraping assembly 3, and a limiting assembly 4. 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 over the dust discharge port 112. The locking switch 13 is operably disposed on the cup body 11 to lock the cover 12 when it is closed. The filter assembly 2 includes a filter screen 21 disposed within the receiving space 111. The dust scraping assembly 3 includes a dust scraper 31 movably disposed on the filter screen 21 and a driving member 32 for driving the dust scraper 31 to move along the filter screen 21. The limiting assembly 4 includes a movable limiting member 41 and an unlocking member 42. The limiting member 41 is movable between a first position and a second position.

[0043] When the limiting member 41 is in the first position, the limiting member 41 can restrict the movement of the unlocking member 42 and restrict the driving member 32 to move within a predetermined range; when the limiting member 41 is in the second position, the limiting member 41 releases the restriction on the unlocking member 42, so that the driving member 32 can move outside the predetermined range and drive the unlocking member 42 to operate the locking switch 13 to release the lock on the cover 12.

[0044] The cup body 11 has an internal receiving space 111 for storing inhaled dust and is connected to the outside through a dust exhaust port 112, ensuring that dust is collected and discharged through the exhaust port 112. The lid 12 is closable at the dust exhaust port 112 and is connected to the cup body 11 via a hinged structure, allowing it to be opened to empty the dust or closed to seal the receiving space 111 when needed. A locking switch 13 can be installed on the outer wall of the cup body 11 and employs an operable mechanical structure to securely lock the lid 12 when closed, preventing accidental opening and dust leakage.

[0045] The filter assembly 2 includes a filter screen 21 disposed within the receiving space 111 and a housing 22. The filter screen 21, typically made of metal mesh or a similar material, is arranged around the outer periphery of the housing 22 and is responsible for intercepting large particles that are drawn in, while allowing air to pass through to maintain the suction efficiency of the vacuum cleaner. The housing 22 provides structural support for the filter screen 21 to prevent the filter screen 21 from deforming during cleaning.

[0046] The scraper 31 is positioned close to the filter screen 21 and can move along the surface of the filter screen 21 to remove attached dust and debris. The drive unit 32 is connected to the scraper 31 and is responsible for translating user operations into movement of the scraper 31. The scraper 31 can be designed as a ring-shaped structure surrounding the outer periphery of the filter screen 21, ensuring that the scraper 31 can cover all areas of the filter screen 21 when it moves, achieving cleaning of all areas of the filter screen 21 without the user needing to disassemble the filter screen 21 or use additional cleaning tools.

[0047] The limiting member 41 and the unlocking member 42 cooperate to switch between a first position and a second position. When the limiting member 41 is in the first position, it abuts against the unlocking member 42, restricting the unlocking member 42 and limiting the movement range of the driving member 32. This prevents accidental activation of the unlocking mechanism during dust removal, ensuring that the cover 12 remains locked and avoiding the risk of dust escaping during dust removal. When the user needs to empty the dust, the limiting member 41 can be switched to the second position. At this time, the limiting member 41 releases its restriction on the unlocking member 42, allowing the driving member 32 to move to a greater range. This, in conjunction with the unlocking member 42, activates the locking switch 13, releasing the cover 12 to open the dust outlet 112, enabling convenient opening of the dust cup and emptying of the waste.

[0048] In one exemplary embodiment, please refer to Figure 1 and Figure 5 As shown, a housing 5 is installed on the outer wall of the cup body 11, a limiting component 4 is disposed inside the housing 5, a slide rail 51 is provided on the inner wall of the housing 5, and the limiting component 41 is slidably disposed on the slide rail 51. The limiting component 41 can slide along the slide rail 51 between a first position and a second position.

[0049] To ensure the stable arrangement and guidance of the dust scraping assembly 3 and the limiting assembly 4, a shell structure with an installation cavity is provided on the outside of the cup body 11 of the dust cup assembly 1, and the installation and guiding structure of the dust scraping assembly 3 and the limiting assembly 4 is integrated inside the shell 5. Specifically, the shell 5 is fixedly installed on the outer wall of the cup body 11, and its shape can match the contour of the outer wall of the cup body 11. It can serve as a gripping structure for the dust collection device for the user to hold, and it can also serve as an installation platform for other functional components, providing the necessary mechanical space and positioning basis for the installation of structures such as the dust scraping assembly 3 and the limiting assembly 4.

[0050] On the inner wall of the housing 5, a set of slide rails 51 extending in a specific direction are designed. These slide rails 51 provide a guiding path for the movement of the limiting member 41. The slide rails 51 can be grooves or track structures, making it difficult for the limiting member 41 to deviate or get stuck during sliding. The slide rails 51 not only help the limiting member 41 to smoothly switch from the first position to the second position along the axial or radial direction (which can be designed according to actual needs) of the cup body 11, but also withstand the external force applied when operating the limiting member 41, ensuring a stable and smooth sliding process without affecting the fitting accuracy of the limiting member 41 with other components.

[0051] Specifically, please refer to Figure 5 and Figure 6 As shown, the limiting member 41 includes a main body 411, a protruding part 412 extending from the main body 411, and a supporting part 413. The protruding part 412 extends out of the housing 5. Pushing the protruding part 412 can move the limiting member 41 to a first position. When the limiting member 41 is in the first position, the supporting part 413 abuts against the unlocking member 42 to restrict the movement of the unlocking member 42.

[0052] The main body 411, as the core load-bearing structure of the limiting member 41, is sized and shaped to fit the slide rail 51 inside the housing 5, forming a sliding fit with the housing 5, enabling smooth movement along a set direction under the guidance of the slide rail 51. The main body 411 can be designed as a block or strip structure, and its material can be engineering plastic or lightweight metal, taking into account strength, rigidity, and sliding resistance control to ensure that the limiting action is neither loose nor sticky.

[0053] The protrusion 412 extending from the main body 411 is in the shape of a button or rod and is an external control component for physical interaction between the user or other components and the limiting member 41. The protrusion 412 passes through the outer shell of the housing 5 and is partially exposed outside the housing 5. Without opening the housing 5, the sliding position of the entire limiting member 41 can be controlled by pushing and pressing the protrusion 412.

[0054] The abutment part 413 is a structure that performs the limiting function. It extends from the main body 411 toward the unlocking member 42, and its shape is designed to form an effective contact surface with the unlocking member 42. When the limiting member 41 is in the first position, the abutment part 413 can abut against the movement path of the unlocking member 42. Its design is adapted to the contact point position, contact area, and resistance direction of the unlocking member 42 to ensure that the unlocking member 42 is effectively blocked in the limited state and cannot be driven by the driving member 32 to perform the unlocking action, thereby preventing the dust cup cover from opening accidentally during the dust removal process. The abutment part 413 can be structurally represented as a short arm, a hook, or a slope. The specific form can be adjusted according to the assembly structure or spatial layout requirements, but its essential function is to limit the unlocking member 42 through mechanical interference.

[0055] In actual use, the limiting member 41 can be held in the second position by default under the action of the reset structure, that is, the supporting part 413 is separated from the unlocking member 42, allowing the driving member 32 to freely drive the dust scraper 31 to scrape dust according to the user's operation, and the unlocking member 42 to perform the opening operation. However, when the dust collection device is installed on the main unit or the user actively pushes the protrusion 412, the limiting member 41 is switched to the first position, the supporting part 413 moves forward and intervenes in the movement path of the unlocking member 42, thereby physically limiting the unlocking member 42 in terms of structure, and limiting the sliding range of the driving member 32, so as to realize the state switching control of the entire dust scraping-opening linkage action.

[0056] Further, please refer to Figure 5 and Figure 6 As shown, to achieve the automatic reset function of the limiting member 41, a first elastic member 43 is connected between the limiting member 41 and the housing 5. The first elastic member 43 provides the elastic force to drive the limiting member 41 from the first position to the second position. This design not only eliminates the need for manual return operation of the limiting member 41 after switching the limiting state, but also ensures that the limiting member 41 can remain in the expected initial state, preventing the device from failing to operate or being accidentally activated during the next use.

[0057] The first elastic element 43 can be a spring, sheet, or other elastic component. One end is connected to the limiting element 41, and the other end is fixed to the internal support structure of the housing 5. In terms of structural arrangement, the elastic element is positioned along the sliding direction of the limiting element 41, allowing it to be gradually compressed and store energy during the movement of the limiting element 41. When the pushing force is released, the elastic force is released, driving the limiting element 41 to slide back along the slide rail 51 to its initial second position. The position and installation method of this elastic element are adapted to the movement direction and stroke length of the limiting element 41, as well as the internal space constraints of the housing 5, to ensure that the elastic restoring force is sufficient to complete the reset.

[0058] In one exemplary embodiment, please refer to Figure 1 , Figure 3 and Figure 5 As shown, the unlocking member 42 is mounted on the mounting base 52 inside the housing 5. The unlocking member 42 has a tongue 421. The housing 5 has a through hole 53 at the corresponding position of the locking switch 13. The tongue 421 passes through the through hole 53. When the unlocking member 42 is driven by the driving member 32, the tongue 421 can pass through the through hole 53 to press the locking switch 13.

[0059] The main function of the unlocking component 42 is to trigger the locking switch 13 under specific conditions through coordinated action with the driving component 32, thereby unlocking and opening the dust cup cover 12. The unlocking component 42 is mounted on the mounting base 52 inside the housing 5, forming a stable and controlled working environment. The mounting base 52 can be fixed (e.g., integrally formed) at a predetermined position on the inner wall of the housing 5, and has the functions of positioning reference and structural support, enabling the unlocking component 42 to be reliably positioned and limiting its invalid displacement in the non-working state.

[0060] The tongue 421 extends outward from the main body of the unlocking member 42, with its end facing the outside of the housing 5 and arranged opposite to the through hole 53 on the housing 5 at the corresponding position of the locking switch 13. When the unlocking member 42 is in the initial position, the tongue 421 is hidden inside the housing 5 and does not interfere with the normal closing of the locking mechanism; when the unlocking member 42 is moved by the driving member 32, the tongue 421 gradually passes through the through hole 53 within a certain stroke and protrudes outward, so that its end can contact and press the pressing part of the locking switch 13 located on the outer wall of the cup body 11, thereby releasing the locking switch 13 from locking the cover 12.

[0061] In one exemplary embodiment, please refer to Figure 5 and Figure 6 As shown, 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 5 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.

[0062] The guide rod 321 serves as a guide structure for the drive component 32. Its end is fixedly installed inside the housing 5 along the axial direction of the cup body 11, providing a reference path for the sliding of the push rod 322. The layout direction of the guide rod 321 is consistent with the main axis of the dust collection device, which is beneficial for the compact arrangement of the overall structure of the device and also facilitates the direct transmission and precise control of force. The guide rod 321 can be made of a material with a low coefficient of friction to ensure low frictional resistance and minimal structural wear during the sliding of the push rod 322, thereby improving the durability and smooth operation of the drive component 32.

[0063] The push rod 322 is slidably connected to the guide rod 321, and one end of it can be connected to the push button 323 and fixedly connected to the scraper 31. Structurally, the push rod 322 slides around the outer periphery of the guide rod 321 or through the guide groove. Its length is designed according to the scraping stroke requirements to ensure that the push rod 322 can drive the scraper 31 to completely cover the effective area of ​​the filter screen 21 during the sliding process. The push button 323 is a component that is directly operated by the user. It is located on the outside of the housing 5 and is fixedly connected to the push rod 322. The user can drive the push rod 322 to slide along the guide rod 321 by manually pushing the push button 323, thereby driving the scraper 31 to move on the filter screen 21.

[0064] To achieve automatic reset after operation, a reset element, which can be a spring or a spring plate structure, can be provided between the push rod 322 and the housing 5. The reset element provides a restoring force after the user releases the push button 323, causing the push rod 322 to automatically retract to the starting position along the guide rod 321. This resets the scraper 31 and releases the drive on the unlocking element 42, ensuring the unlocking mechanism remains in the released state only when needed. This reset design prevents operational abnormalities caused by misoperation or structural jamming.

[0065] Please refer to Figure 5 As shown, when the limiting member 41 is in the first position, the unlocking member 42 can be fixed in the movement path of the push rod 322, thereby forming a blocking effect, limiting the axial travel of the push rod 322, and thus limiting the movement range of the entire driving member 32. When the limiting member 41 is in the first position, the abutting part 413 moves forward to the active area of ​​the unlocking member 42 and abuts against the unlocking member 42, forming physical interference with the unlocking member 42. At this time, the unlocking member 42 is fixed and cannot slide or rotate. The unlocking member 42 is arranged in the forward path of the push rod 322. When the limiting member 41 restricts the unlocking member 42, the front end of the push rod 322 will interfere with the unlocking member 42 during movement and cannot move further, forming an effective block, thereby limiting the movement range of the driving member 32, so that the driving member 32 cannot move to the position where the unlocking member 42 is driven to perform the unlocking operation.

[0066] exist Figure 5 and Figure 6In the embodiment shown, in order to achieve stability and guidance of the unlocking member 42 and avoid problems such as deviation, jamming or excessive frictional resistance during the driving process, the mounting base 52 is provided with a guide post 521, and the unlocking member 42 is provided with a guide hole 422. The guide post 521 passes through the guide hole 422. The unlocking member 42 can slide along the guide post 521 toward the locking switch 13, so that the tongue 421 passes through the through hole 53.

[0067] Specifically, the mounting base 52 is provided with at least one guide post 521 extending along the operating direction. The guide post 521 may be cylindrical or approximately prismatic in shape, and the material has a certain rigidity and wear resistance to ensure stable fit during long-term sliding. Correspondingly, the unlocking component 42 is provided with a guide hole 422 that matches the guide post 521. The guide hole 422 penetrates through the body of the unlocking component 42 or is embedded inside the body to fit the guide post 521. After assembly, the guide post 521 passes through the guide hole 422, forming a sliding fit, allowing the unlocking component 42 to slide linearly toward the locking switch 13 under the guidance of the guide post 521.

[0068] Since the unlocking member 42 needs to move under the push of the driving member 32 and extend through the through hole 53 of the housing 5 via its tongue 421 to press the locking switch 13, its movement path must be aligned with the pressing part 131 of the locking switch 13. The sliding fit between the guide post 521 and the guide hole 422 satisfies this guiding requirement, so that the unlocking member 42 moves in the desired direction during the process of being driven by the driving member 32.

[0069] Specifically, please refer to Figures 5 to 7 As shown, in order to achieve the linkage between the driving component 32 and the unlocking component 42, the end of the push rod 322 is provided with a first guide surface 324, and the unlocking component 42 is provided with a second guide surface 423 that matches the first guide surface 324. When the limiting component 41 is in the second position, pushing the push button 323 can move the end of the push rod 322 to the second guide surface 423, so that the first guide surface 324 pushes against the second guide surface 423, so that the unlocking component 42 moves along the guide post 521 toward the locking switch 13, and the tongue 421 passes through the through hole 53.

[0070] The first guide surface 324 is located at the front end of the push rod 322, in the end region along its sliding direction. Its shape can be designed as a slope, arc, or other contact surface with a certain angle. Its function is to allow the push rod 322 to gradually contact the second guide surface 423 on the unlocking member 42 and generate force when the push rod 322 slides close to the unlocking member 42. The second guide surface 423, as the force-bearing interface on the unlocking member 42, matches the shape of the first guide surface 324 and also has a certain angle or curvature to facilitate smooth force transmission and guide the movement process. This relative slope structure design allows for a gradual contact and progressive advancement dynamic process between the guide surfaces, avoiding sudden impacts or structural obstruction, resulting in a smoother and gentler movement.

[0071] In operation, when the limiting member 41 is in the second position, the restriction on the unlocking member 42 is released. In this state, the user pushes the push button 323 to drive the push rod 322 to slide along the guide rod 321. The end of the push rod 322 gradually approaches the unlocking member 42. When the first guide surface 324 contacts the second guide surface 423, continuing to push the push rod 322 will force a sliding contact between the guide surfaces, thereby forming an oblique pushing force, causing the unlocking member 42 to slide towards the locking switch 13 along its guide post 521. As the sliding continues, the tongue 421 on the unlocking member 42 gradually protrudes through the through hole 53 of the housing 5, and finally contacts the pressing part of the locking switch 13, applying the triggering force required for unlocking, releasing the cover 12 from the locked state, and realizing the opening function.

[0072] Further, please refer to Figure 1 and Figure 5 As shown, the mounting base 52 is provided with a buckle 522, and a second elastic member 44 is provided between the mounting base 52 and the unlocking member 42. The buckle 522 is engaged with the unlocking member 42 to restrict the unlocking member 42 on the mounting base 52, and the second elastic member 44 is used to drive the unlocking member 42 to slide away from the locking switch 13.

[0073] To prevent the unlocking component 42 from dislodging from its installation position due to external force or vibration during movement, the mounting base 52 is provided with a locking buckle 522 structure for limiting its position. The buckle 522 is a hook-shaped or boss-shaped structure designed at the end of the guide path, and can hold the unlocking component 42 within the limited range of the mounting base 52 by elastic deformation after installation.

[0074] The reset function of the unlocking element 42 relies on a second elastic element 44 disposed between it and the mounting base 52. The second elastic element 44 can be in the form of a compression spring, torsion spring 14, or spring sheet, and is installed between the unlocking element 42 and the mounting base 52. The second elastic element 44 is moderately compressed in the initial state. When the push rod 322 drives the unlocking element 42 to complete the sliding action, the user releases the operating force, and the elastic element releases the stored elastic potential energy, driving the unlocking element 42 to slide in the opposite direction along the guide post 521, that is, to move away from the locking switch 13, so that the tongue 421 retracts from the through hole 53 of the housing 5, restoring the unlocked state.

[0075] exist Figure 8 and Figure 9 In the illustrated embodiment, the movement of the unlocking member 42 is a rotation around a fixed point. In this embodiment, the mounting base 52 is provided with a shaft hole 61, and the unlocking member 42 is provided with a pivot 62. The pivot 62 is pivotally connected to the shaft hole 61, and the unlocking member 42 can rotate around the pivot 62, so that the tongue 421 passes through the through hole 53.

[0076] Specifically, the mounting base 52 is positioned at a predetermined location inside the housing 5 as a fixed structure, and has a machined shaft hole 61. This shaft hole 61 has dimensions and axial orientation that match those of the pivot 62 to form a rotational fit. The unlocking component 42 includes a pivot 62 integrated into its body or side wing. This pivot 62 is inserted into the shaft hole 61 during assembly and forms a rotational connection with it. The pivot 62 can be manufactured by integral molding or as a separate insert. Its material is preferably a material with good wear resistance and structural strength to ensure smooth operation and durability under high-frequency operation.

[0077] In this structural configuration, the unlocking element 42 no longer slides linearly along the guide structure, but rotates around the pivot 62 under the guidance of the pivot 62. When the user pushes the driving element 32, the driving force is transmitted to the force-bearing part of the unlocking element 42 through the push rod 322 or other force transmission components, generating a deflection torque, thereby causing the unlocking element 42 to rotate around the pivot 62. During the rotation, the tongue 421 located at one end of the unlocking element 42 moves accordingly and eventually passes through the through hole 53 provided in the housing 5 at the corresponding position of the locking switch 13, realizing the pressing trigger of the locking switch 13.

[0078] Specifically, in Figure 8 and Figure 9In the embodiment shown, the end of the push rod 322 is provided with a first guide surface 324, and the unlocking member 42 is provided with a second guide surface 423 that matches the first guide surface 324. When the limiting member 41 is in the second position, pushing the push button 323 can move the end of the push rod 322 to the second guide surface 423, so that the first guide surface 324 pushes against the second guide surface 423, so that the tongue 421 of the unlocking member 42 rotates toward the locking switch 13, and the tongue 421 passes through the through hole 53.

[0079] Specifically, the end of the push rod 322 is provided with a first guide surface 324, and the unlocking member 42 is provided with a matching second guide surface 423. When the limiting member 41 is in the second position, the user pushes the push button 323 to make the push rod 322 slide forward. The first guide surface 324 at the end of the push rod 322 then contacts the second guide surface 423 on the unlocking member 42. During the continuous pushing process, the contact force between the inclined surfaces pushes the unlocking member 42 to rotate around the pivot 62, thereby realizing the unlocking action.

[0080] When the limiting member 41 is in the second position, i.e., when the engagement between the push rod 322 and the unlocking member 42 is not restricted, the user pushes the push button 323 to move the push rod 322 forward along the guide rod 321. When the first guide surface 324 of the push rod 322 reaches and contacts the second guide surface 423 of the unlocking member 42, as the pushing force continues to be applied, the force formed between the inclined surfaces causes the unlocking member 42 to rotate around its pivot 62. During this process, the tongue 421 of the unlocking member 42 rotates with the unlocking member 42 as a whole and gradually passes through the corresponding through hole 53 of the housing 5. Finally, the user presses the locking switch 13 located outside the through hole 53, releasing the dust cup cover 12 from the locked state and completing the opening action.

[0081] exist Figure 8 and Figure 9 In the embodiment shown, in order to ensure that the unlocking member 42 can return to its initial state in a timely manner after completing the unlocking action, a second elastic member 44 is provided between the mounting base 52 and the unlocking member 42. The second elastic member 44 is used to drive the tongue 421 of the unlocking member 42 to rotate away from the locking switch 13.

[0082] When the limiting member 41 is in the second position, and the user pushes the push rod 322 to rotate the unlocking member 42, the second elastic member 44 will be compressed or twisted, thereby storing elastic potential energy. At this time, the tongue 421 gradually rotates to a position close to the locking switch 13 and presses through the through hole 53. When the push rod 322 is released and the external driving force is removed, the second elastic member 44 immediately releases the stored energy, using the elastic force in the opposite direction to drive the unlocking member 42 to rotate around the pivot 62, causing the tongue 421 to quickly exit the through hole 53 and move away from the locking switch 13, completing the closed loop of the action. This structural design effectively ensures that the unlocking member 42 will not remain in the unlocked position when not in operation, preventing accidental opening of the dust cup cover or structural fatigue caused by the unlocking member 42 pressing against the locking switch 13 for a long time.

[0083] In one exemplary embodiment, please refer to Figures 1 to 4 , Figure 10 As shown, the cover 12 includes a hinged end 121 and a free end 122. The hinged end 121 is hinged to the cup body 11, and the free end 122 is provided with a slot 123. 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 can rotate around the hinge part 133 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 slot 123 in the locked position to lock the cover 12. By pressing the pressing part 131, the locking switch 13 can be switched to the unlocked position to release the engagement between the hook part 132 and the slot 123 and release the lock on the cover 12.

[0084] Specifically, one end of the lid 12 is configured as a hinged end 121, which can be connected to the cup body 11 via a pivot or hinge structure, allowing the lid 12 to rotate freely relative to the cup body 11 around the connection point. The other end of the lid 12 is a free end 122, which is responsible for forming a seal with the cup body 11 in the closed state. The free end 122 is provided with a slot 123 for achieving mechanical engagement. The position and opening direction of the slot 123 are designed to ensure that when the lid 12 is rotated closed to the final position, it can engage with the hook portion 132 of the locking switch 13 to form a reliable engagement.

[0085] The locking switch 13, which cooperates with the lid 12, is a pivotable component. Its structure includes a pressing part 131, a hook part 132, and a hinge part 133 between the two. The hinge part 133 is located in the middle of the locking switch 13 and can be hinged to the cup body 11 through a pivot or other rotating connection structure, so that the locking switch 13 can rotate around the hinge part 133 as a fulcrum. The hook part 132 is located near the free end 122 of the lid 12, and its shape matches the slot 123 of the free end 122 of the lid 12. When the lid 12 is closed, it can be engaged with the slot 123 to form a locking action and complete the locking of the lid 12. The pressing part 131 is located at the end of the locking switch 13 away from the hook part 132, facing the through hole 53 and the tongue 421 of the unlocking member 42, so that the tongue 421 can trigger the unlocking action by pressing.

[0086] During use, when the cover 12 is rotated to the closed state, the slot 123 of its free end 122 aligns with the hook portion 132 of the locking switch 13. The user can lightly press the cover 12 to spring the hook portion 132 into the slot 123, completing the mechanical locking. In this state, due to the mechanical engagement between the hook portion 132 and the slot 123, the cover 12 can no longer be opened around the hinge end 121, thus preventing the dust cup from accidentally opening during operation. If it is necessary to open the cover 12 for ash emptying or cleaning operations, simply press the pressing part 131 of the locking switch 13 to rotate the locking switch 13 around the hinge portion 133, thereby causing the hook portion 132 to disengage from the slot 123 and releasing the lock on the cover 12.

[0087] Specifically, please refer to Figure 1 and Figure 2 As shown, a torsion spring 14 is provided between the hinge end 121 and the cup body 11. The torsion spring 14 is used to provide the elastic force to drive the lid 12 to rotate and open the dust outlet 112. A third elastic member 15 is provided between the pressing part 131 and the outer wall of the cup body 11. The third elastic member 15 is used to provide the elastic force to drive the locking switch 13 to remain in the locked position.

[0088] A torsion spring 14 is provided between the hinge end 121 of the lid 12 and the cup body 11. One end of the torsion spring 14 is fixed to the hinge part 133 of the cup body 11, and the other end is connected to the rotating structure of the lid 12. When the lid 12 is in the closed state, the torsion spring 14 is in a torsional state and stores a certain amount of elastic potential energy. When the locking switch 13 is released and the lid 12 is unlocked, the torsion spring 14 releases its elastic force, pushing the lid 12 to rotate automatically around its hinge axis, thereby opening the dust outlet 112.

[0089] To ensure that the locking switch 13 remains locked when not pressed, a third elastic element 15 is provided between the pressing part 131 of the locking switch 13 and the outer wall of the cup body 11. This elastic element can be a compression spring, a spring sheet, or a rubber elastomer structure, and is installed between the pressing part 131 and the outer wall of the cup body 11. When the user does not apply external force, the third elastic element 15 is in a naturally extended state, pushing the pressing part 131 outward to rebound, causing the locking switch 13 to automatically rotate back to the initial locked position around its hinge part 133.

[0090] Please refer to Figure 11 As shown, this disclosure also provides a cleaning device, which includes a body 7 and the aforementioned dust collection device 10 detachably mounted on the body 7. When the dust collection device 10 is mounted on the body 7, the limiting member 41 of the dust collection device 10 is restricted to a first position by the body 7; when the dust collection device 10 is removed from the body 7, the limiting member 41 of the dust collection device 10 returns to a second position.

[0091] Specifically, the dust collection device 10 has a limiting member 41 that can slide between a first position and a second position. This limiting member 41 has an outwardly protruding extension 412, serving as a component for user control or external structural triggering. In the overall structure of the cleaning equipment, the body 7 is designed with a pressing area or mating surface at the corresponding mounting position that can contact the protruding extension 412 of the limiting member 41. When the dust collection device 10 is installed on the body 7, the structure of the body 7 will press against the protruding extension 412 of the limiting member 41, forcing the limiting member 41 to remain in the first position. At this time, the abutting part 413 of the limiting member 41 is located in the movement path of the unlocking member 42, preventing the unlocking member 42 from moving under the drive of the push rod 322, thereby further limiting the travel range of the push rod 322. This ensures that during equipment operation, the dust scraping action will not accidentally trigger the unlocking mechanism, preventing dust leakage caused by accidental opening of the dust cup cover.

[0092] When the user needs to maintain or clean the dust collection device 10, it can be completely removed from the body 7. Once disassembly is complete, the pressing force of the body 7 on the protrusion 412 is released. At this time, the first elastic member 43, located between the limiting member 41 and the housing 5, comes into play, providing elastic restoring force and springing the limiting member 41 back from the first position to the second position. This reset action releases the movement restriction of the unlocking member 42, allowing the user to freely operate the push rod 322 in the disassembled state. This not only allows for scraping dust off the filter screen 21, but also enables the unlocking member 42 to press the locking switch 13, opening the cover 12 for waste disposal or internal cleaning.

[0093] In summary, the dust collection device and cleaning equipment provided in this disclosure can establish an action state isolation between the dust scraping operation and the opening of the dust cup lid. Through the cooperative mechanism between the limiting component, the unlocking component, and the driving component, when the limiting component is in the first position, the range of motion of the unlocking component and the driving component is restricted, so that the user can only perform the dust scraping operation, avoiding the opening of the dust cup lid and preventing dust from escaping or being misoperated; when the limiting component moves to the second position, the driving component can move further, driving the unlocking component to trigger the locking switch, thereby realizing the automatic unlocking of the lid.
