TECHNICAL FIELD

[0001] The utility model relates to domestic appliance technical field especially relates to a dust cup subassembly and cleaning equipment. BACKGROUND

[0002] The basic working principle of cleaning equipment such as dust collector, acararium is that airflow is generated by high-speed operation of motor to suck dust and chippings into the machine interior, and the purpose of cleaning is achieved.

[0003] In cleaning equipment such as dust collector, acararium, dust cup is usually configured, and the dust cup has two cavities, one side is ash storage cavity, and one side is cyclone cavity, and some challenges are encountered when processing long hair and large particle materials and other sundries, hair is easy to wind on the outer wall of coarse filter element, and manual cleaning is needed for the user, and the suction of cleaning equipment is reduced after the filter hole is blocked, which is not conducive to the suction of hair, dust and mites, and the cleaning effect is affected.

[0004] Therefore, it is urgent to solve the problem that hair and other sundries easily block the coarse filter element inside the dust cup and affect the cleaning effect. UTILITY MODEL CONTENTS

[0005] The utility model provides a dust cup subassembly and cleaning equipment to solve the problem that hair and other sundries easily block the coarse filter element inside the dust cup and affect the cleaning effect.

[0006] In order to realize the above-mentioned purpose, the utility model provides a dust cup subassembly, which comprises:

[0007] Dust cup, the dust cup is internally hollow structure, the dust cup has air inlet and air outlet;

[0008] Wind baffle, the wind baffle is arranged in the dust cup, the wind baffle is surrounded by cyclone cavity internally, the ash storage cavity is formed between the wind baffle and the dust cup, the first end of the wind baffle has dust throwing port, and the dust throwing port is open towards the air outlet;

[0009] Air guide, the air guide is connected between the second end of the wind baffle and the dust cup, and the air guide forms the air inlet channel that is connected with the cyclone cavity and the air inlet;

[0010] Coarse filter element, the coarse filter element is located in the cyclone cavity.

[0011] This utility model provides a dust cup assembly. The first end of the baffle has a dust-throwing port, and a guide component is connected between the side wall of the second end of the baffle and the dust cup. An air inlet channel is formed within the guide component, connecting the cyclone chamber and the air inlet. During use, air enters the cyclone chamber through the air inlet and spirals forward within the cyclone chamber. Heavier dust and hair, due to centrifugal force, spiral forward along the inner wall of the baffle, causing dust, hair, and other debris to be thrown out through the dust-throwing port into the dust storage chamber. The dust-throwing port is an open opening facing the air outlet, allowing dust to enter the dust storage chamber more smoothly. This reduces the accumulation of dust, hair, and other debris on the coarse filter within the cyclone chamber, preventing clogging and improving cleaning efficiency. It also reduces maintenance requirements and maintains a longer-lasting cleaning effect.

[0012] In one possible implementation, the air guide has a guide surface tangential to the inner wall of the cyclone cavity. The guide surface tangentially guides the airflow, allowing the airflow entering the cyclone cavity to move tangentially along the inner wall of the cyclone cavity under the guidance of the guide surface. This helps to form a stable rotating airflow, reducing the generation of eddies and turbulence, thereby improving the suction and cleaning effect of the cleaning equipment, reducing airflow turbulence and energy loss within the cyclone cavity, and thus improving the energy efficiency of the cleaning equipment.

[0013] In one possible implementation, the dust cup assembly further includes a dust baffle movably disposed at the air inlet, the dust baffle being configured to switch between a closed state (closing the air inlet) and an open state (opening the air inlet) under the influence of airflow. The dust baffle has both open and closed states to control airflow and prevent dust leakage.

[0014] In one possible implementation, the dust-blocking component includes a fixed section and a movable section connected to each other, the fixed section being connected to the inner wall of the air inlet, and the movable section being movably disposed within the air inlet channel;

[0015] When the dust-blocking component is in the closed state, the movable section abuts against the guide surface;

[0016] When the dust-blocking component is in the open state, there is a gap between the movable section and the guide surface.

[0017] When the dust baffle is closed, it shuts off the air inlet, preventing dust and debris from falling into the cyclone chamber. This helps avoid secondary contamination when the cleaning equipment is turned off or moved, and also protects the internal components from external dust and debris, extending the equipment's lifespan. When the dust baffle is open, it allows airflow into the cyclone chamber, maintaining the cleaning equipment's normal operating efficiency and suction power.

[0018] In one possible implementation, the cyclone chamber is located at the center of the ash storage chamber; and the cross-section of the cyclone chamber is circular in the axial direction perpendicular to the dust cup.

[0019] The circular cross-section helps create a smooth, continuous rotating airflow. This airflow pattern maximizes the effect of centrifugal force, causing dust and other debris to be more effectively thrown towards the edge of the cyclone chamber, thereby improving the separation efficiency. The circular cross-section also reduces the generation of eddies and turbulence, minimizing energy loss and maintaining airflow stability and efficient operation of the cleaning equipment.

[0020] In one possible implementation, one end of the coarse filter extends to the second end of the baffle and is closed, while the other end of the coarse filter extends out of the dust outlet and connects to the inner wall of the dust cup. The coarse filter has a filter chamber inside, and its outer wall has multiple coarse filter holes that connect the filter chamber and the cyclone chamber. The coarse filter holes are channels between the filter chamber and the cyclone chamber, allowing air to pass through while blocking larger particles, thus achieving a primary filtration effect.

[0021] In one possible implementation, the air outlet is connected to the filter chamber, and a dust drain cover is provided at the end of the dust cup facing away from the ash-throwing port. The air outlet is used to discharge filtered air, which helps ensure that the air can smoothly leave the dust cup assembly after passing through the filter chamber, reducing air resistance and improving overall efficiency. The dust drain cover can be opened to empty the accumulated dust in the ash storage chamber, facilitating maintenance and cleaning.

[0022] In one possible implementation, the dust cup assembly further includes a fine filter disposed between the air outlet and the filter chamber. The fine filter is used to perform secondary filtration, which can filter even finer dust particles.

[0023] In one possible implementation, the dust cup assembly further includes an operating button disposed on the dust cup, the operating button including a locking portion, the dust emptying cover having a hook portion, and the operating button being movably disposed on the outer wall of the dust cup such that the locking portion extends into the hook portion.

[0024] The user operates this button to lock and release the dust emptying cover. The locking mechanism extends into the hook section to lock the cover, making it difficult to open and improving its stability during closure, thus preventing dust leakage from the ash storage chamber. The locking mechanism disengages from the hook section, releasing the dust emptying cover, which can then be opened to clean dust and debris from the ash storage chamber.

[0025] In one possible implementation, the operating button further includes a pressing part and a rotating part. The pressing part is connected to one end of the locking part relative to the hook part, and the rotating part is disposed at the connection position between the pressing part and the locking part. The operating button is rotatably disposed on the dust cup via the rotating part.

[0026] This utility model also provides a cleaning device, including: a body, a drive component, and the aforementioned dust cup assembly.

[0027] In one possible implementation, the drive unit is disposed on the body, the drive unit has a nozzle, the dust cup assembly is detachably disposed on the body, the body has a suction channel, the air inlet of the dust cup assembly is connected to the outlet end of the suction channel, and the nozzle is connected to the air outlet of the dust cup assembly.

[0028] In the dust cup assembly and cleaning equipment provided in this embodiment of the utility model, the dust-throwing port is open, which means that there is no obstruction or sealing structure at the dust-throwing port. This open design allows dust, hair and other debris to move along the inner wall of the baffle after being subjected to centrifugal force in the cyclone chamber and can be directly thrown out from the open end of the baffle, that is, leaving the cyclone chamber from the dust-throwing port and entering the dust storage chamber. This effectively separates dust, hair and other debris from the air and collects them, reducing the residence time of debris in the cyclone chamber and improving the separation efficiency.

[0029] The dust cup assembly and cleaning equipment provided in this embodiment of the utility model can effectively remove particles of different sizes through multi-stage filtration and cyclone centrifugal separation, thereby extending the service life of the cleaning equipment and improving its working efficiency.

[0030] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by a dust cup assembly and cleaning equipment provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0072] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0073] During vacuum cleaner use, although the coarse filter can effectively filter some larger dust, hair and other impurities, hair can easily get tangled on the outer wall of the coarse filter, and large dust particles can easily clog the coarse filter pores. This not only affects the filtration effect, but may also make it difficult to clean the coarse filter, thus affecting the operation of the vacuum cleaner.

[0074] This application provides a dust cup assembly and cleaning device that optimizes the separation path of airflow and debris, reducing the problem of hair and other debris entangled and adhering to the outer wall of the coarse filter element, thus clogging the coarse filter pores. This significantly improves the efficiency and reliability of the cleaning device in handling dust and hair, thereby reducing maintenance needs and maintaining a longer-lasting cleaning effect.

[0075] The dust cup assembly and cleaning device provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0076] The present invention provides a cleaning device, including but not limited to a vacuum cleaner and a mite remover.

[0077] refer to Figure 1 As shown, this utility model embodiment provides a dust cup assembly for cleaning equipment. The dust cup assembly is mainly used to collect dust, hair and other impurities filtered by the cleaning equipment.

[0078] refer to Figure 2 , Figure 3 and Figure 4 As shown, this utility model embodiment provides a dust cup assembly, including: a dust cup 10, a baffle 20, a guide 30, and a coarse filter 40. The dust cup 10 has a hollow internal structure and has an air inlet 11 and an air outlet 13. The baffle 20 is disposed inside the dust cup 10, and the interior of the baffle 20 forms a cyclone cavity 21. A dust storage cavity 12 is formed between the baffle 20 and the dust cup 10. The first end of the baffle 20 has a dust throwing port 22, which is an open opening facing the air outlet 13. The guide 30 is connected between the side wall of the second end of the baffle 20 and the dust cup 10. An air inlet channel 31 is formed inside the guide 30, which connects the cyclone cavity 21 and the air inlet 11. The coarse filter 40 is located inside the cyclone cavity 21.

[0079] This utility model provides a dust cup assembly. The first end of the baffle 20 has a dust-throwing port 22. An air guide 30 is connected between the side wall of the second end of the baffle 20 and the dust cup 10. The air guide 30 forms an air inlet channel 31 that connects the cyclone chamber 21 and the air inlet 11. During use, air enters the cyclone chamber 21 from the air inlet 11 through the air inlet channel 31 and spirals forward within the cyclone chamber 21. Heavier dust and hair are dispersed due to centrifugal force. The air flows spirally along the inner wall of the baffle 20, causing dust, hair, and other debris to be thrown out from the dust-throwing port 22 and into the dust-collecting chamber 12. The dust-throwing port 22 is an open opening facing the air outlet 13, which makes it easier for dust to enter the dust-collecting chamber 12 from the dust-throwing port 22 without obstruction. This reduces the problem of dust, hair, and other debris accumulating on the coarse filter 40 in the cyclone chamber 21 and causing the coarse filter 40 to become clogged, thus improving the cleaning effect, reducing maintenance needs, and maintaining a longer-lasting cleaning effect.

[0080] In one possible implementation, the air inlet 11 may be located on the side wall of the dust cup 10, and the air outlet 13 may be located at the end of the dust cup 10 away from the air inlet 11.

[0081] In one possible implementation, along the axial direction of the dust cup 10, the first end and the second end of the baffle 20 are located at opposite ends of the baffle 20, i.e., the dust outlet 22 and the air inlet channel 31 are located at opposite ends of the baffle 20. The axial direction of the dust cup 10 is referenced... Figure 4 The arrow Y in the diagram indicates the direction.

[0082] Since the air guide 30 is connected to the side wall of the second end of the baffle 20, after the air enters the cyclone cavity 21, it moves in a circular motion along the inner wall of the baffle 20 due to the obstruction of the baffle 20. Then, under the suction force provided by the drive component 90 of the cleaning equipment, the air in the cyclone cavity 21 moves along the axial direction of the dust cup 10 from the air inlet 31 toward the dust outlet 22. That is, the air in the cyclone cavity 21 moves from the second end of the baffle 20 to the first end of the baffle 20, thus realizing the spiral forward motion of the air in the cyclone cavity 21.

[0083] refer to Figure 3 As shown, Figure 3 Arrow P in the diagram indicates the direction of air flow as it carries dust and other debris from the ash-throwing port 22 into the ash-storage chamber 12 within the cyclone chamber 21.

[0084] As the air inside the cyclone chamber 21 spirals forward, under the action of centrifugal force, it effectively separates and discharges impurities into the ash storage chamber 12, reducing the accumulation of impurities on the coarse filter element 40 inside the cyclone chamber 21. This reduces the problem of clogging of the coarse filter holes 42 on the coarse filter element 40, which not only improves the separation efficiency of the cleaning equipment, but also extends the service life of the coarse filter element 40, reducing the frequency and difficulty of maintenance for users.

[0085] The ash-throwing port 22 is an open opening facing the air outlet 13, meaning that the ash-throwing port 22 has no obstruction or sealing structure. This open design allows dust, hair, and other debris to move along the inner wall of the baffle 20 after being subjected to centrifugal force in the cyclone chamber and can be directly thrown out from the open end of the baffle 20, that is, leaving the cyclone chamber 21 from the ash-throwing port 22 and entering the ash storage chamber 12. This effectively separates dust, hair, and other debris from the air and collects them, reducing the residence time of debris in the cyclone chamber 21 and improving the separation efficiency.

[0086] In one possible implementation, the wind deflector 20, the dust cup 10, and the air guide 30 can be a single integral structure, which helps to improve the structural strength of the connection and can also reduce the problem of poor sealing in the air intake channel 31, thus ensuring dust collection efficiency.

[0087] In one possible implementation, the air guide 30 can be in the form of a tubular structure, such as a square tube or a trapezoidal tube, to facilitate the formation of an air inlet channel 31 within the air guide 30.

[0088] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4 As shown, the windbreak 20 includes a side panel 23 and a bottom plate 24. The side panel 23 is formed into a cylindrical shape. The first end of the side panel 23 forms the ash discharge port 22. The second end of the side panel 23 is connected to the edge of the bottom plate 24. The air guide 30 can be connected to the second end of the side panel 23.

[0089] In one possible implementation, the dust cup 10 can be made of a transparent material, allowing the user to see the dust stored in the dust storage chamber 12 directly, facilitating timely cleaning.

[0090] In one possible implementation, the air guide 30 has a guide surface 32 that is tangent to the inner wall of the cyclone cavity 21. This guide surface 32 is one side of the inner wall of the air inlet channel 31.

[0091] Since the guide surface 32 is tangential to the inner wall of the cyclone cavity 21, the guide surface 32 plays the role of tangentially guiding the airflow. This allows the airflow entering the cyclone cavity 21 to move tangentially along the inner wall of the cyclone cavity 21 under the guidance of the guide surface 32. This helps to form a stable rotating airflow, reduces the generation of eddies and turbulence, thereby improving the suction and cleaning effect of the cleaning equipment. It also reduces the turbulence and energy loss of the airflow in the cyclone cavity 21, thereby improving the energy efficiency of the cleaning equipment.

[0092] The tangential guiding effect of the guiding surface 32 helps the airflow to form a strong rotational motion in the cyclone cavity 21, which enhances the effect of centrifugal force and can effectively throw heavier dust, hair and other debris to the outer wall of the cyclone cavity 21, thereby achieving an effective debris separation effect.

[0093] In one possible implementation method, refer to Figure 4 and Figure 5 As shown, the dust cup assembly also includes a dust baffle 50 movably disposed at the air inlet 11. The dust baffle 50 is configured to switch between a closed state (closing the air inlet 11) and an open state (opening the air inlet 11) under the action of airflow. The dust baffle 50 has both open and closed states to control the airflow and prevent dust leakage.

[0094] When a sufficiently strong airflow enters the air inlet 11, the dust baffle 50 deforms and opens under the thrust of the airflow on the dust baffle 50, opening the air inlet 11. When the airflow stops entering the air inlet 11, the thrust of the airflow on the dust baffle 50 disappears, and the dust baffle 50 returns to the closed state under its own elastic restoring force, blocking the air inlet 11 and closing the air inlet 11, so that air and debris cannot enter or escape through the air inlet 11.

[0095] In one possible implementation, the dust baffle 50 includes a fixed section 51 and a movable section 52 connected to each other. The fixed section 51 is connected to the inner wall of the air inlet 11, and the movable section 52 is movably disposed within the air inlet channel 31. When the dust baffle 50 is in the closed state, the movable section 52 abuts against the guide surface 32, preventing air from entering the air inlet channel 31 through the air inlet 11. The air inlet 11 is closed, ensuring that air and debris will not enter or escape through the air inlet 11 when cleaning equipment is not in use, so as to avoid pollution and reduce the need for cleaning and maintenance.

[0096] By closing the air inlet 11 with the dust baffle 50, the dust baffle 50 prevents dust and debris in the cyclone chamber 21 from falling out of the air inlet 11, which helps to avoid secondary pollution when the cleaning equipment is turned off or moved. It can also protect the internal components of the cleaning equipment from the intrusion of dust and debris from the external environment and extend the service life of the cleaning equipment.

[0097] When the dust baffle 50 is in the open position, there is a gap between the movable section 52 and the guide surface 32. This gap allows air to pass through, enabling airflow to enter the cyclone chamber 21 to maintain the normal operating efficiency and suction power of the cleaning equipment.

[0098] In one possible implementation, the fixing section 51 can be connected to the inner wall of the air inlet 11 by a snap-fit ​​connection. Alternatively, a connection hole can be opened in the inner wall of the air inlet 11, and the fixing section 51 can be embedded in the connection hole and press-fitted with the connection hole to connect the fixing section 51 to the inner wall of the air inlet 11.

[0099] In one possible implementation, the fixed section 51 and the movable section 52 are integrally formed as a single structure.

[0100] In one possible implementation, the dust-blocking component 50 is a thin-walled structural component, and the thickness of the connection position between the movable section 52 and the fixed section 51 is small, that is, the thickness of the connection position between the movable section 52 and the fixed section 51 is smaller than the thickness of the movable section 52 and smaller than the thickness of the fixed section 51, so that the connection position between the movable section 52 and the fixed section 51 is easy to undergo elastic deformation, so that the movable section 52 can move within the air inlet channel 31.

[0101] In this application, the dust baffle 50 automatically opens or closes according to the working status of the cleaning equipment, which improves the convenience of use. The dust baffle 50 can flexibly switch between opening and closing, which can improve the precise control of airflow.

[0102] In one possible implementation, the cyclone chamber 21 is located at the center of the dust collection chamber 12. This structure effectively utilizes the space within the dust cup 10, reduces the overall volume of the dust cup assembly, and allows dust and other debris to be thrown out from a 360° radius around the dust outlet 22. The thrown debris falls into the dust collection chamber 12, improving the separation efficiency of dust and other debris from air. Furthermore, the central location of the cyclone chamber 21 in the dust collection chamber 12 also helps improve the center of gravity balance of the dust cup assembly, thereby enhancing the stability of the cleaning equipment during use.

[0103] In one possible implementation, the cross-section of the cyclone chamber 21 is circular in the axial direction perpendicular to the dust cup 10. The circular cross-section helps to create a smooth, continuous rotating airflow. This airflow pattern maximizes the effect of centrifugal force, causing dust and other debris to be more effectively thrown towards the edge of the cyclone chamber 21, thereby improving the separation efficiency. The circular cross-section also reduces the generation of eddies and turbulence, minimizing energy loss and maintaining airflow stability and efficient operation of the cleaning equipment.

[0104] In other possible implementations, the cross-section of the cyclone chamber 21 may also be polygonal in the axial direction perpendicular to the dust cup 10.

[0105] In one possible implementation method, refer to Figure 3 , Figure 4 and Figure 5 As shown, the coarse filter element 40 has a filter chamber 41 inside, and the outer wall of the coarse filter element 40 has a plurality of coarse filter holes 42 that connect the filter chamber 41 and the cyclone chamber 21.

[0106] The coarse filter element 40 is used for preliminary filtration to block dust and debris entering the cyclone chamber 21. It can effectively remove larger particles. The air filtered by the coarse filter element 40 enters the filter chamber 41 through the coarse filter hole 42. The filter chamber 41 is a space inside the coarse filter element 40, used to contain the filtered air. The coarse filter hole 42 is a channel between the filter chamber 41 and the cyclone chamber 21, allowing air to pass through while blocking larger particles, thus achieving a primary filtration effect.

[0107] In one possible implementation, the coarse filter element 40 has a cylindrical structure. The number and diameter of the coarse filter holes 42 are not specifically limited here. The multiple coarse filter holes 42 can be arranged along the circumference and radial direction of the coarse filter element 40 to improve the filtration effect of the coarse filter element 40.

[0108] In one possible implementation, one end of the coarse filter element 40 extends to the second end of the baffle 20 and is closed, while the other end of the coarse filter element 40 extends out of the dust outlet 22 and is connected to the inner wall of the dust cup 10. This structure allows the air entering the cyclone chamber 21 to have a larger contact area with the coarse filter element 40, increasing the contact area between the air and the coarse filter element 40, which helps to improve filtration efficiency because more airflow can pass through the coarse filter element 40, making it easier for the coarse filter element 40 to filter out more impurity particles.

[0109] One end of the coarse filter element 40 extends to the second end of the windbreak element 20 and is closed. The closed structure can prevent airflow from entering the filter chamber 41 directly without filtration, effectively control the airflow path, ensure that all air is filtered, effectively protect other filter structures downstream of the airflow path, and improve the dust removal effect.

[0110] In one possible implementation, a mounting bracket 43 is connected to one end of the coarse filter element 40 that extends out of the dust outlet 22. The mounting bracket 43 is connected to the inner wall of the dust cup 10 to achieve the installation and fixation of the coarse filter element 40.

[0111] In one possible implementation, the mounting bracket 43 and the inner wall of the dust cup 10 can be connected by a snap-fit ​​or an interference fit.

[0112] In one possible implementation, a seal 44 is provided between the mounting bracket 43 and the inner wall of the dust cup 10. The seal 44 can be an elastic element such as a rubber ring. The seal 44 can prevent air leakage and block dust in the ash storage chamber 12.

[0113] In one possible implementation, the dust ejection port 22 faces the air outlet 13, which is connected to the filter chamber 41. A dust collection cover 60 is provided at the end of the dust cup 10 facing away from the dust ejection port 22. In this example, the air outlet 13 and the dust collection cover 60 are located at opposite ends of the dust cup 10 in the axial direction.

[0114] The air outlet 13 allows filtered air to exit, helping to ensure that air flows smoothly out of the dust cup assembly after passing through the filter chamber 41, reducing air resistance and improving overall efficiency. The dust collection cover 60 can be opened to empty the dust accumulated in the dust collection chamber 12, facilitating maintenance and cleaning.

[0115] With this design, users can easily open the dust cover 60 to empty the collected dust and particles, keeping the system clean and running efficiently.

[0116] In one possible implementation method, refer to Figure 4 and Figure 6As shown, one side of the dust cover 60 is hinged to the dust cup 10, and the other side of the dust cover 60 is mechanically locked to the dust cup 10.

[0117] In one possible implementation, the dust cup assembly also includes an operating button 14 disposed on the dust cup 10. The operating button 14 includes a locking portion 142. The dust cover 60 has a hook portion 61. The operating button 14 is movably disposed on the outer wall of the dust cup 10 so that the locking portion 142 extends into the hook portion 61.

[0118] The user operates the control button 14 to lock and release the dust collection cover 60. The locking part 142 extends into the hook part 61 to lock the dust collection cover 60, making it difficult to open and improving the stability of its closure, thus preventing dust leakage from the ash storage chamber 12. When the locking part 142 disengages from the hook part 61, the dust collection cover 60 is released, allowing it to be opened and used to clean dust and debris from the ash storage chamber 12.

[0119] In one possible implementation, the locking part 142 typically has a protrusion, and the hook part 61 is typically a recessed structure. The hook part 61 is designed to accommodate the size and shape of the protrusion to ensure that the protrusion can be smoothly inserted into the hook part 61 and remain stable. When the protrusion extends into the hook part 61, the inner wall of the hook part 61 is in close contact with the outer surface of the protrusion, achieving mechanical locking and ensuring that the dust cover 60 will not be easily opened during use.

[0120] In one possible implementation, the operating button 14 further includes a pressing part 141 and a rotating part 143. The pressing part 141 is connected to one end of the locking part 142 relative to the hook part 61, and the rotating part 143 is disposed at the connection position of the pressing part 141 and the locking part 142. The operating button 14 is rotatably disposed on the dust cup 10 via the rotating part 143.

[0121] When in use, the user presses the pressing part 141 of the operation button 14, causing the operation button 14 to rotate around the central axis of the rotating shaft part 143. The pressing part 141 moves toward the inside of the dust cup 10, and the locking part 142 moves away from the dust cup 10, thereby causing the locking part 142 to disengage from the hook part 61 and unlocking the dust cover 60.

[0122] In one possible implementation, the pivot portion 143 is also provided with a torsion spring, which is used to reset the operation button 14 when the pressing portion 141 is released, so as to ensure that the locking portion 142 can stably cooperate with the hook portion 61 to achieve the locking effect of the dust cover 60.

[0123] In one possible implementation, the operating button 14 can be a one-piece molded structure.

[0124] In one possible implementation method, refer to Figure 3 and Figure 4 As shown, the dust cup assembly also includes a fine filter element 70, which is disposed between the air outlet 13 and the filter chamber 41. The fine filter element 70 is used to achieve secondary filtration, which can filter even finer dust particles.

[0125] In one possible implementation, the fine filter element 70 is located within the airflow channel between the air outlet 13 and the filter chamber 41. The fine filter element 70 can be a HEPA filter. The main component of HEPA is polyester fiber, which has a high air filtration capacity and antibacterial properties. It can be used to filter dust and fine particles in the air, including pollen, smoke, bacteria, pet dander, and human dander.

[0126] refer to Figure 1 , Figure 7 and Figure 8 As shown, this utility model also provides a cleaning device, including: a body 80, a drive component 90, and the aforementioned dust cup assembly.

[0127] In one possible implementation, a drive unit 90 is disposed on a body 80, the drive unit 90 has a nozzle 91, a dust cup assembly is detachably disposed on a body 80, a suction channel 81 is provided inside the body 80, the air inlet 11 of the dust cup assembly is connected to the outlet end of the suction channel 81, and the nozzle 91 is connected to the air outlet 13 of the dust cup assembly.

[0128] In one possible implementation, a control button 82 is provided on the outer wall surface of the housing 80. The control button 82 can be used to control the locking and unlocking of the dust cup assembly. The control button 82 can be a push button.

[0129] It should be noted that the locking structure for locking the dust cup assembly to the body 80 can refer to existing structures and is not specifically limited here, as long as it can stably lock the dust cup assembly to the body 80 and release the dust cup assembly.

[0130] The dust cup assembly is detachably mounted on the body 80, facilitating cleaning and maintenance of the cleaning equipment. Users can easily remove the dust cup assembly for emptying or cleaning, improving the ease of use and maintenance efficiency of the cleaning equipment. Figure 8 As shown, arrow A indicates the direction of movement of the dust cup assembly as it is disassembled from the body 80.

[0131] refer to Figure 1As shown, arrow P points to the direction of airflow. The inlet of the suction channel 81 is the dust inlet, located at the front of the body 80. The air inlet 11 of the dust cup assembly is connected to the outlet of the suction channel 81, so that the air entering the suction channel 81 from the dust inlet enters the air inlet 11 of the dust cup assembly through the outlet of the suction channel 81.

[0132] The drive unit 90 is a motor, which provides suction force so that air continuously enters the suction channel 81 from the dust inlet, and then enters the air inlet 11 of the dust cup assembly through the outlet end of the suction channel 81. The air entering the air inlet 11 enters the cyclone chamber 21 through the air inlet channel 31 in the air guide 30, and spirals forward in the cyclone chamber 21. It undergoes preliminary filtration through the coarse filter 40. The air filtered by the coarse filter 40 enters the filter chamber 41, and then undergoes secondary filtration through the fine filter 70 before being discharged from the air outlet 13, thus achieving the dust removal effect.

[0133] The dust cup assembly and cleaning equipment provided in this embodiment of the utility model can effectively remove particles of different sizes through multi-stage filtration and cyclone centrifugal separation, thereby extending the service life of the cleaning equipment and improving its working efficiency.
