Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a dust collection device and a cleaning device. Background Technology

[0002] With the development of science and technology, cleaning equipment is being used more and more widely in people's daily lives, such as vacuum cleaners and mite removers. Mite removers mainly use a beating plate or roller brush to vibrate the surface of the fabric to remove debris from the fabric, and then use a suction motor to generate negative pressure to suck the dust into a dust collection device, which separates the dust and air and collects the dust and debris.

[0003] However, some models of mite removers are prone to problems when dealing with long hair and large particles, such as hair and other debris getting tangled on the outer wall of the filter cartridge inside the cyclone chamber, causing the filter holes to become clogged. This requires manual cleaning by the user, and the clogged filter holes can reduce the suction power of the vacuum cleaner, making it difficult to suck up hair, dust and mites, thus affecting the cleaning effect. Utility Model Content

[0004] In view of the above problems, this application provides a dust collection device and a cleaning equipment that can easily remove hair and foreign objects from the cyclone chamber and ensure the suction power of the cleaning equipment.

[0005] This application provides a dust collection device for cleaning equipment, comprising: a dust cup, the dust cup including a cup body and a separator, the cup body having a hollow inner cavity and a dust outlet communicating with the inner cavity, the separator being disposed inside the cup body and dividing the inner cavity of the cup body into a dust storage cavity and a cyclone cavity, the side wall of the cup body having an air inlet and an air outlet communicating with the cyclone cavity, and the top of the separator having a dust discharge port communicating with the dust storage cavity and the cyclone cavity; a cover assembly, the cover assembly being movably connected to the dust cup to open and close the dust outlet; and a filter assembly, the filter assembly being disposed inside the dust cup, the filter assembly including a filter cylinder extending into the cyclone cavity, the filter cylinder being located between the air inlet and the air outlet in the airflow path, the filter cylinder being used to separate dust from airflow entering the cyclone cavity, and the cross-sectional shape of the filter cylinder along its own axial direction being polygonal.

[0006] When the cleaning equipment is working, dust, hair, and other debris are drawn in through the air inlet into the cyclone chamber. There, they are subjected to centrifugal force, which causes the debris to spiral along the inner wall of the cyclone chamber. This reduces the accumulation of debris on the surface of the filter cartridge within the cyclone chamber, thus mitigating filter clogging. When the dust and debris reach the ash-throwing port, they are thrown into the ash storage chamber. During cleaning, the dust in the ash storage chamber can be emptied through the ash outlet, and hair entangled and adhered to the inner wall of the cyclone chamber, the outer wall of the filter cartridge, and the filter holes can also be removed. This ensures smooth airflow within the dust collection device, allowing the cleaning equipment to maintain stable suction and guaranteeing cleaning efficiency and effectiveness.

[0007] In one possible implementation, the cross-section of the filter cartridge along its own axial direction is one of a triangle, a square, or a trapezoid.

[0008] Thus, the filter cylinder has a relatively regular shape and a relatively flat perimeter, which is conducive to the formation of a spiral airflow around the filter cylinder. In addition, the shape and structure of the filter cylinder are relatively simple and easy to manufacture.

[0009] In one possible implementation, the ash outlet is located at the top of the cup body, the cover assembly seals the ash outlet, the ash throwing port is located between the top end face of the separator and the cover assembly, and the cover assembly is adapted to guide impurities in the cyclone chamber to the ash storage chamber.

[0010] The ash outlet design makes it easy for users to clean dust and is simple to operate. The ash discharge port position design allows dust to enter the ash storage chamber, reducing the phenomenon of dust back suction caused by airflow disturbance.

[0011] In one possible implementation, the cyclone chamber and the ash storage chamber are arranged side by side along a first direction, which is perpendicular to the height direction of the dust cup; at least a portion of the structure of the cover assembly on one side surface facing the cyclone chamber is formed as a guide surface, which extends obliquely away from the air inlet along the first direction and from the cyclone chamber toward the ash storage chamber.

[0012] By designing inclined and extended guide surfaces, dust and debris are guided, reducing their residence time in the cyclone chamber and allowing them to move to the dust storage chamber under the action of airflow, thereby improving dust collection efficiency.

[0013] In one possible implementation, the air inlet and the air outlet are located at the bottom of the side wall of the cup body; the separator includes: a first separator located between the cyclone chamber and the ash storage chamber; a second separator located at the bottom of the cyclone chamber and forming the bottom wall of the cyclone chamber; and an air duct located at the bottom of the second separator, the air duct defining an inlet air duct and an outlet air duct, the inlet air duct connecting the cyclone chamber and the air inlet respectively, the outlet air duct connecting the cyclone chamber and the air outlet respectively, and, along the airflow path, the inlet air duct and the outlet air duct are located on both sides of the filter assembly.

[0014] When airflow enters through the bottom inlet, it first passes through the air duct formed by the air intake section into the cyclone chamber. During the spiral ascent, dust and gas separation is completed. The separated dust particles are thrown into the dust storage chamber under centrifugal force, while the purified airflow is discharged from the outlet through the outlet duct. This layout design achieves directional control of the airflow path, creating spatial isolation between the inlet and outlet paths, avoiding a decrease in separation efficiency due to airflow turbulence, and improving the stability of the dust and gas separation process.

[0015] In one possible implementation, the cyclone cavity has a circular cross-section, and the air duct portion includes: a first air duct structure that extends spirally around the central axis of the cyclone cavity and defines the air inlet duct; and a second air duct structure that defines the air outlet duct, wherein the first air duct structure at least partially surrounds the second air duct structure.

[0016] The circular cross-section of the cyclone chamber helps to create a smooth, continuous rotating airflow. This airflow pattern maximizes the effect of centrifugal force, allowing dust and other debris to be more effectively thrown towards the edge of the cyclone chamber, thereby improving air-to-dust separation efficiency. The circular cross-section also helps to reduce the generation of eddies and turbulence, reducing energy loss and maintaining airflow stability and efficient operation of the cleaning equipment. The layout design of the first air duct structure, which can at least partially surround the second air duct structure, improves space utilization and allows the inlet and outlet airflows to flow in opposite directions, effectively extending the dust separation path. The spiral structure of the first air duct structure enhances the airflow rotation speed, while the circular cavity ensures a uniform distribution of the centrifugal force field, improving dust-to-air separation efficiency. Thus, the strong centrifugal force generated by the spiral air inlet design of the first air duct structure can quickly separate lightweight hair, and the circular cavity can further enhance the centrifugal force, allowing dust and other debris to be more effectively thrown towards the edge of the cyclone chamber. The two work together to improve dust-to-air separation efficiency.

[0017] In one possible implementation, the second partition has a connecting port, and the second air duct structure includes a first air duct section and a second air duct section. The first air duct section extends along the height direction of the dust cup and communicates with the connecting port. The second air duct section extends along a direction perpendicular to the height direction of the dust cup. One end of the second air duct section communicates with the first air duct section, and the other end communicates with the air outlet.

[0018] By designing the first and second air duct sections, the second air duct structure achieves a combination of vertical and horizontal air duct layout, realizing a smooth transition in airflow direction, reducing turbulence generation, helping to optimize airflow path, and improving dust and gas separation efficiency.

[0019] In one possible implementation, the second partition has a connecting groove, and the connecting port is located on the bottom wall of the connecting groove; the filter cylinder surrounds the filter cavity, and the side wall of the filter cylinder has a plurality of filter holes connecting the cyclone cavity and the filter cavity; the filter cylinder has an open end and a closed end opposite to each other along the height direction of the dust cup, the open end is inserted into the connecting groove, and the closed end is located in the cyclone cavity; from the open end toward the closed end, the width of the cross-section of the filter cylinder gradually decreases.

[0020] The filter cartridge's gradually decreasing cross-sectional width design makes it roughly a frustum-shaped tube sealed at one end. Hair and other debris entangled on the outer wall of the filter cartridge can exit through the smaller diameter end, facilitating cleaning. The closed-off end of the filter cartridge prevents unfiltered airflow from directly entering the filtration chamber, effectively controlling the airflow path and ensuring all air is filtered. This protects downstream filtration structures and improves dust removal efficiency.

[0021] In one possible implementation, the dust collection device further includes: a filter element disposed between the filter chamber and the communication port; and / or, the cup body includes a first sidewall and a second sidewall opposite to each other along a second direction, the air inlet and the air outlet are both disposed on the first sidewall, the dust cup further includes a dust baffle plate disposed at the connecting corner of the separator and the first sidewall and located on one side of the ash storage chamber, the dust baffle plate is disposed adjacent to the ash throwing port, and the dust baffle plate has filter holes.

[0022] As the airflow moves from the cyclone chamber to the outlet, the filter element performs secondary filtration on the airflow passing through the connection port, trapping dust particles that may escape from the ash storage chamber back to the cyclone chamber. This effectively prevents lightweight debris such as hair from moving backwards due to airflow disturbances. By designing the filter element and opening filter holes, a synergistic effect of physical blocking and pore size control can be achieved. This ensures unidirectional dust-air separation while maintaining normal ventilation volume, improving the trapping efficiency of fine particles, and preventing dust re-entrainment that may be caused by airflow disturbances.

[0023] In one possible implementation, the cover assembly includes: an upper cover support adapted to block the ash outlet, the guide surface being formed on the upper cover support; and an upper cover body covering the upper cover support.

[0024] The separate design of the top cover support and the top cover body allows the top cover body to be disassembled separately during maintenance and cleaning, avoiding frequent disassembly and assembly, improving cleaning convenience, and reducing maintenance difficulty while ensuring performance. In addition, the top cover support has a guide surface to improve dust and gas separation efficiency.

[0025] This application also provides a cleaning device, including a device body and the aforementioned dust collection device.

[0026] The cleaning device of this embodiment can clean the dust storage chamber and cyclone chamber of the dust collection device. It can remove the dust and impurities collected in the dust storage chamber, and remove hair and foreign objects that adhere to the inner wall of the cyclone chamber, wrap around the outer wall of the filter component, or block the filter holes and air vents, thus ensuring the suction power of the cleaning device and ensuring the cleaning effect of the cleaning device.

[0042] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] With the development of science and technology, cleaning equipment is increasingly widely used in people's daily lives, such as vacuum cleaners and mite removers. Mite removers mainly use a beating plate or roller brush to vibrate the fabric surface, causing debris to fall off. A suction motor then generates negative pressure to draw dust into a dust collection device, which separates the dust and air, collecting the dust and debris. However, some models of mite removers are prone to problems when dealing with long hair and large particles. Hair and other debris can become entangled on the outer wall of the filter cartridge within the cyclone chamber, causing filter blockage. This requires manual cleaning by the user. Furthermore, clogged filter cartridges can reduce the vacuum cleaner's suction power, hindering the intake of hair, dust, and mites, thus affecting cleaning effectiveness.

[0044] In view of this, this application provides a dust collection device and a cleaning equipment. When the cleaning equipment is working, dust, hair, and other debris are drawn in and enter the cyclone chamber from the air inlet with the airflow. They are then subjected to the centrifugal force of the cyclone, which causes the debris to spiral along the inner wall of the cyclone chamber. This reduces the accumulation of debris on the surface of the filter cartridge within the cyclone chamber, thus reducing the problem of filter pore blockage. When the dust and debris move to the ash-throwing port under the action of centrifugal force, the debris is thrown from the ash-throwing port into the ash-storage chamber. When cleaning the dust collection device, the dust in the ash-storage chamber can be emptied through the ash outlet, and hair entangled and adhered to the inner wall of the cyclone chamber, the outer wall of the filter cartridge, and the filter pores can also be removed through the ash outlet. This ensures smooth airflow inside the dust collection device, allowing the cleaning equipment to maintain stable suction and ensuring cleaning efficiency and effectiveness.

[0045] The specific embodiments are described below with reference to the accompanying drawings. Wherein, x represents the first direction and y represents the second direction.

[0046] This application provides a dust collection device 10 for cleaning equipment, including but not limited to a mite remover, and also a vacuum cleaner. Optionally, the dust collection device 10 can be detachably installed on the equipment body, so that the user can easily remove the dust collection device 10 for emptying or cleaning, which helps to improve the ease of use and maintenance efficiency of the cleaning equipment.

[0047] refer to Figures 1 to 5 The dust collection device 10 may include a dust cup 100, a cover assembly 200, and a filter assembly 300.

[0048] The dust cup 100 includes a cup body 110 and a separator 120. The cup body 110 has a hollow inner cavity 111 and an ash outlet 112 communicating with the inner cavity 111. The separator 120 is disposed inside the cup body 110 and divides the inner cavity 111 of the cup body 110 into an ash storage cavity 1111 and a cyclone cavity 1112. The side wall of the cup body 110 is provided with an air inlet 113 and an air outlet 114 communicating with the cyclone cavity 1112. The top of the separator 120 is provided with an ash throwing port 1201 communicating with the ash storage cavity 1111 and the cyclone cavity 1112. The cover assembly 200 is movably connected to the dust cup 100 to open and close the ash outlet 112. The cover assembly 200 is adapted to guide impurities in the cyclone cavity 1112 to the ash storage cavity 1111.

[0049] The filter assembly 300 is disposed within the dust cup 100. The filter assembly 300 includes a filter cartridge 310 extending into the cyclone chamber 1112. In the airflow path, the filter cartridge 310 is located between the air inlet 113 and the air outlet 114. The filter cartridge 310 is used to separate dust from the airflow entering the cyclone chamber 1112. The cross-section of the filter cartridge 310 along its own axial direction is polygonal; for example, the cross-section of the filter cartridge 310 along its own axial direction can be triangular, square, trapezoidal, or other shapes. Thus, the filter cartridge 310 has a relatively regular shape and relatively flat peripheral walls, which is conducive to forming a spiral airflow around the filter cartridge 310. Furthermore, the shape and structure of the filter cartridge 310 are relatively simple, making it easy to manufacture.

[0050] The dust cup 100 has a hollow interior, and its cross-section perpendicular to the axis can be circular, elliptical, or any other arbitrary shape. The dust cup 100 has an air inlet 113, an air outlet 114, and a dust outlet 112. The air inlet 113 can be connected to the vibration device of a mite removal device or the floor brush device of a cleaning device. The air outlet 114 can be connected to the suction motor of the mite removal device or cleaning device, and the suction motor can apply negative pressure to the inner cavity 111 of the dust cup 100 through the air outlet 114.

[0051] The ash outlet 112 can be opened after the cleaning equipment has finished cleaning to facilitate the removal of dust and debris collected in the dust cup 100. For example, the user can manually open the ash outlet 112 and pour out the dust and debris. Optionally, the ash outlet 112 can be provided with a cover plate for opening and closing the ash outlet 112. For example, the cover plate can be pivotally connected to the periphery of the ash outlet 112, or it can be snap-fitted, or other connection methods can be used.

[0052] The separator 120 is disposed in the inner cavity 111 of the cup body 110. The separator 120 can divide the inner cavity 111 of the cup body 110 into a ash storage cavity 1111 and a cyclone cavity 1112. The separator 120 has an ash throwing port 1201, which connects the ash storage cavity 1111 and the cyclone cavity 1112. The air inlet 113 is located on the side wall of the cup body 110 and is connected to the cyclone cavity 1112.

[0053] Since the separator 120 divides the interior of the dust cup 100 into a dust storage chamber 1111 and a cyclone chamber 1112, and a dust throwing port 1201 is provided in the separator 120, the dust throwing port 1201 connects the dust storage chamber 1111 and the cyclone chamber 1112, and the air inlet 113 is located on the side wall of the dust cup 100, when in use, air enters the interior of the dust cup 100 from the air inlet 113 and finally leaves the dust cup 100 from the air outlet 114.

[0054] The filter assembly 300 can be disposed within the dust cup 100. The filter assembly 300 includes a filter cartridge 310 extending into the cyclone chamber 1112. In the airflow path, the filter cartridge 310 is located between the air inlet 113 and the air outlet 114. The filter cartridge 310 is used to separate dust and gas in the airflow entering the cyclone chamber 1112.

[0055] Specifically, after the airflow enters the cyclone chamber 1112, it can form a spiral airflow around the filter assembly 300, thereby throwing the dust and impurities filtered by the filter assembly 300 from the cyclone chamber 1112 into the ash storage chamber 1111 for storage through the ash throwing port 1201, while the filtered air can flow to the air outlet 114 after passing through the filter assembly 300.

[0056] In this embodiment of the dust collection device 10, when the cleaning equipment is working, the dust, hair and other debris sucked in enter the cyclone chamber 1112 from the air inlet 113 along with the airflow. They are subjected to the centrifugal force of the cyclone. The centrifugal force causes the debris to spiral along the inner wall of the cyclone chamber 1112, reducing the accumulation of debris on the surface of the filter cartridge 310 in the cyclone chamber 1112 and reducing the problem of clogging of the filter holes 311 of the filter cartridge 310. When the dust and debris move to the position of the ash throwing port 1201 under the action of centrifugal force, the debris is thrown from the ash throwing port 1201 into the ash storage chamber 1111.

[0057] When cleaning the dust collection device 10, the dust in the ash storage chamber 1111 can be emptied through the ash outlet 112, and the hair wrapped around and adhered to the inner wall of the cyclone chamber 1112, the outer wall of the filter cylinder 310, and the filter hole 311 can be removed through the ash discharge port. This ensures smooth airflow inside the dust collection device 10, allowing the cleaning equipment to maintain stable suction and ensure cleaning efficiency and effectiveness.

[0058] Optionally, the cup body 110 and the separator 120 can be an integrally connected structure, which helps to improve the structural strength of the connection.

[0059] Optionally, the dust cup 100 can be made of transparent material, allowing users to see the dust stored in the dust storage chamber 1111 at a glance, making it convenient to clean in a timely manner.

[0060] Optionally, the ash discharge port 1201 may be rectangular, circular, or other shapes. The air inlet 113 may be rectangular, trapezoidal, or other shapes.

[0061] Optionally, the dust ejection port 1201 and the air inlet 113 are located on different side walls of the cyclone chamber 1112, and there is an angle between the central axis of the dust ejection port 1201 and the central axis of the air inlet 113. This structure helps to optimize the airflow path and more effectively utilize the cyclone effect to separate dust particles from the air.

[0062] Optionally, the angle between the central axis of the ash-throwing port 1201 and the central axis of the air inlet 113 can be 80°-120°, such as 80°, 90°, 100°, 110°, and 120°. This helps to use the centrifugal force of the cyclone to throw heavier dust and other debris entering the cyclone chamber 1112 from the air inlet 113 towards the inner wall of the cyclone chamber 1112, and then discharge them into the ash storage chamber 1111 through the ash-throwing port 1201. Here, the central axis of the ash-throwing port 1201 refers to the reference line passing through the center of the ash-throwing port 1201, and the central axis of the air inlet 113 refers to the reference line passing through the center of the air inlet 113.

[0063] Optional, refer to Figure 1 and Figure 2 The dust collection device 10 also includes a bottom cover 400, which is detachably disposed at the end of the cup body 110 away from the cover assembly 200, to facilitate maintenance inside the dust cup 100.

[0064] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5 The ash outlet 112 is located at the top of the cup body 110, and the lid assembly 200 covers the ash outlet 112. The ash discharge port 1201 is located between the top end face of the separator 120 and the lid assembly 200.

[0065] Specifically, when the cover assembly 200 is closed, the dust outlet 112 at the top of the cup body 110 will be completely sealed to prevent dust from overflowing. During the cleaning process, the dust separated in the cyclone chamber 1112 can enter the dust storage chamber 1111 for temporary storage through the dust discharge port 1201 at the top of the separator 120. When it is necessary to clean the dust in the dust storage chamber 1111, the cover assembly 200 is opened, and the dust accumulated in the dust storage chamber 1111 can be poured out directly through the top dust outlet 112 without disassembling the internal components of the dust cup 100.

[0066] Optionally, a first seal 211 may be designed between the cover assembly 200 and the dust cup 100. The first seal 211 may be a sealing ring, which surrounds the cover assembly 200 to prevent dust leakage.

[0067] Thus, the design of the ash outlet 112 makes it easy for users to clean the dust and is simple to operate. The design of the ash throwing outlet 1201 allows the dust to fall naturally into the ash storage chamber 1111 under the action of centrifugal force, reducing the phenomenon of dust back suction caused by airflow disturbance.

[0068] In some embodiments, the cover assembly 200 is adapted to guide impurities within the cyclone chamber 111 to the ash storage chamber 111. For example, a flow guiding structure, such as a flow guide plate or flow guide surface, can be provided on the cover assembly 200. The flow guiding structure can be integrally formed with the cover assembly 200, or it can be mechanically connected to the cover assembly 200. In this way, the cover assembly 200 can guide the flow of impurities, making it easier for impurities to enter the ash storage chamber 1111, reducing the retention of impurities in the cyclone chamber 1112, and reducing the risk of blockage.

[0069] In some embodiments, combined with Figures 3 to 5 In the dust collection device 10, the cyclone chamber 1112 and the ash storage chamber 1111 are arranged side by side along a first direction (i.e., the x-direction), which is perpendicular to the height direction of the dust cup 100; at least a portion of the structure of the cover assembly 200 on one side surface facing the cyclone chamber 1112 is formed as a guide surface 201, which extends obliquely in the direction away from the air inlet 113 along the first direction and from the cyclone chamber 1112 toward the ash storage chamber 1111.

[0070] The guide surface 201 can be an inclined structure formed on the surface of the cover assembly 200, and can be in the form of a plane, a curved surface, etc., and can be used to change the airflow direction to control the movement trajectory of dust.

[0071] Specifically, in the first direction, the guide surface 201 on the inner side of the cover assembly 200 gradually rises from the cyclone cavity 1112 side to the ash storage cavity 1111 side, forming a slope structure. When the airflow carrying dust enters the cyclone cavity 1112, it is subjected to the centrifugal force of the cyclone. The centrifugal force of the cyclone causes the debris to spiral along the inner wall of the cyclone cavity 1112. When the dust and debris move to the inner side of the cover assembly 200 under the action of centrifugal force, they will move obliquely towards the ash throwing port 1201 along the guide surface 201. The debris is thrown from the ash throwing port 1201 into the ash storage cavity 1111.

[0072] By designing an inclined and extended guide surface 201, dust and debris are guided, reducing the residence time of dust and debris in the cyclone chamber 1112, and allowing dust and debris to move directionally to the ash storage chamber 1111 under the action of airflow, thereby improving dust collection efficiency.

[0073] In some embodiments, combined with Figure 1 , Figure 3 and Figure 4 The air inlet 113 and the air outlet 114 are located at the bottom of the side wall of the cup body 110; the separator 120 includes a first separator 121, a second separator 122 and an air duct 123. The first separator 121 is located between the cyclone chamber 1112 and the ash storage chamber 1111. The second separator 122 is located at the bottom of the cyclone chamber 1112 and forms the bottom wall of the cyclone chamber 1112. The air duct 123 is located at the bottom of the second separator 122 and defines the air inlet air duct 1231 and the air outlet air duct 1232. The air inlet air duct 1231 is connected to the cyclone chamber 1112 and the air inlet 113 respectively. The air outlet air duct 1232 is connected to the cyclone chamber 1112 and the air outlet 114 respectively. Along the airflow path, the air inlet air duct 1231 and the air outlet air duct 1232 are located on both sides of the filter assembly 300.

[0074] The first partition 121 can be an isolation structure set between the cyclone cavity 1112 and the ash storage cavity 1111. It can be implemented by vertical partition, arc-shaped partition, etc. The first partition 121 divides the hollow cavity inside the dust cup 100 into the adjacent ash storage cavity 1111 and cyclone cavity 1112 through its own blocking effect. The first partition 121 can guide the airflow to form a rotational motion in the cyclone cavity 1112.

[0075] The second partition 122 can be used to seal the end of the cyclone cavity 1112 away from the cover assembly 200. It can also be provided with a connecting groove for fixing the filter assembly 300, which can ensure that the airflow forms an effective rotation path in the cyclone cavity 1112, and help increase the separation efficiency of dust and other debris from the air.

[0076] The air duct section 123 can be a flow guide structure located below the second partition section 122. It can be implemented by spiral channel, split pipe, etc. It can be used to guide the airflow to enter from the air inlet 113 and form a spiral upward path, and then be discharged through the air outlet duct 1232 after filtration.

[0077] Specifically, when the airflow enters from the air inlet 113 at the bottom, it first enters the cyclone chamber 1112 through the air inlet duct 1231 formed by the air duct section 123. During the spiral ascent, the dust and gas are separated. The separated dust particles are thrown into the dust storage chamber 1111 under the action of centrifugal force, while the purified airflow is discharged from the air outlet 114 through the air outlet duct 1232.

[0078] This layout design enables directional control of the airflow path, creating spatial isolation between the inlet and outlet air paths. This avoids a decrease in separation efficiency due to airflow turbulence and improves the stability of the dust-gas separation process.

[0079] Optionally, the side partition is arc-shaped, making the cyclone cavity 1112 nearly cylindrical.

[0080] Optionally, the bottom partition is in the form of a horizontal panel.

[0081] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5 The cyclone cavity 1112 has a circular cross-section. The air duct section 123 includes a first air duct structure 1233 and a second air duct structure 1234. The first air duct structure 1233 extends spirally around the central axis of the cyclone cavity 1112. The first air duct structure 1233 defines an inlet air duct 1231, and the second air duct structure 1234 defines an outlet air duct 1232. The first air duct structure 1233 at least partially surrounds the second air duct structure 1234.

[0082] The circular cross-section of the cyclone chamber 1112 helps to create a smooth, continuous rotating airflow. This airflow pattern maximizes the effect of centrifugal force, allowing dust and other debris to be more effectively thrown towards the edge of the cyclone chamber 1112, thereby improving air-dust separation efficiency. The circular cross-section also helps to reduce the generation of eddies and turbulence, reducing energy loss and thus maintaining airflow stability and efficient operation of the cleaning equipment.

[0083] The first air duct structure 1233 extends spirally around the central axis, which can guide the airflow to generate swirling motion. The second air duct structure 1234 defines the outlet air duct 1232, which can be a straight-through or zigzag air duct. The first air duct structure 1233 can at least partially surround the second air duct structure 1234, that is, the first air duct structure 1233 can at least partially wrap the second air duct structure 1234, and a coaxial nested layout can be adopted.

[0084] The layout design of the first air duct structure 1233, which at least partially surrounds the second air duct structure 1234, can improve space utilization and also allow the inlet and outlet airflows to flow in opposite directions, effectively extending the dust separation path. The spiral structure of the first air duct structure 1233 can enhance the airflow rotation speed, and the circular cavity can ensure a uniform distribution of the centrifugal force field, improving dust and gas separation efficiency.

[0085] Thus, the strong centrifugal force generated by the spiral air intake design of the first air duct structure 1233 can quickly separate light hair, and the circular cavity can further increase the centrifugal force, so that dust and other debris are more effectively thrown to the edge of the cyclone cavity 1112. The two work together to improve the dust and gas separation efficiency.

[0086] In some embodiments, referring to FIG / 3, the second partition 122 has a communication port, and the second air duct structure 1234 includes a first air duct section and a second air duct section. The first air duct section extends along the height direction of the dust cup 100 and communicates with the communication port. The second air duct section extends along the direction perpendicular to the height direction of the dust cup 100. One end of the second air duct section communicates with the first air duct section, and the other end communicates with the air outlet 114.

[0087] Specifically, when the airflow carrying dust enters the cyclone chamber 1112, the dust and air are separated under the action of centrifugal force. The separated airflow enters the first air duct section through the connecting port of the second partition 122 and flows along the first air duct section. Then it turns and enters the second air duct section and flows horizontally, and finally is discharged from the air outlet 114.

[0088] Thus, by designing the first and second air duct sections, the second air duct structure 1234 is arranged in a combination of vertical and horizontal air duct layout, achieving a smooth transition in airflow direction, reducing turbulence generation, and helping to optimize the airflow path and improve dust and gas separation efficiency.

[0089] In some embodiments, combined with Figure 3 The second partition 122 has a connecting groove, and the connecting port is located on the bottom wall of the connecting groove; the filter cylinder 310 surrounds the filter chamber 320, and the side wall of the filter cylinder 310 has a plurality of filter holes 311 that connect the cyclone chamber 1112 and the filter chamber 320; the filter cylinder 310 has an open end and a closed end that are opposite to each other along the height direction of the dust cup 100, the open end is inserted into the connecting groove, and the closed end is located in the cyclone chamber 1112; from the open end toward the closed end, the width of the cross section of the filter cylinder 310 gradually decreases.

[0090] The connecting groove can be a groove structure provided on the second partition 122, which can be used to fix the open end of the filter cylinder 310. The connecting groove can be interference-fitted with the filter cylinder 310. The filter cavity 320 can be a cavity formed by the filter cylinder 310, which can be used to accommodate the clean airflow entering through the filter hole 311. The filter hole 311 can be a hole opened on the side wall of the filter cylinder 310, which can be circular, elliptical, polygonal, etc., allowing airflow to pass through but blocking dust particles from entering the filter cavity 320.

[0091] The design of the filter cartridge 310 with a gradually decreasing cross-sectional width makes the filter cartridge 310 roughly a truncated cone-shaped tube sealed at one end. Hair and other debris wrapped around the outer wall of the filter cartridge 310 can leave the outer wall of the filter cartridge 310 from the end with the smaller outer diameter, making it easy to clean the hair and other debris wrapped around the outer wall of the filter cartridge 310.

[0092] Optionally, the longitudinal section of the filter cartridge 310 is trapezoidal. One end of the filter cartridge 310 is closed. The closed structure can prevent airflow from entering the filter chamber 320 directly without being filtered by the filter cartridge 310, effectively controlling the airflow path and ensuring that all air is filtered by the filter cartridge 310. This effectively protects other filter structures downstream of the airflow path and improves the dust removal effect.

[0093] In some embodiments, combined with Figure 3 and Figure 5 The dust collection device 10 also includes a filter element 330, which can be disposed between the filter chamber 320 and the connecting port. The filter element 330 can perform secondary filtration on the airflow after the initial filtration by the filter cartridge 310, so as to reduce the risk of impurities being sucked into the suction motor.

[0094] Optionally, the number of filter elements 330 can be two or more to improve the filtration effect. Multiple filter elements 330 can be made of the same material or different materials.

[0095] Optionally, the filter assembly 300 includes two filter elements 330, namely a sponge and a HEPA filter. The sponge is located on the side closer to the filter cartridge 310, and the HEPA filter is located on the side closer to the air outlet 114. The HEPA filter can filter tiny dust particles of 0.3 μm, making the exhaust air cleaner.

[0096] Optionally, a second sealing element 312 may be provided at the mounting end of the filter cartridge 310. Optionally, the second sealing element 312 may be a sealing ring, which surrounds the outer periphery of the mounting end of the filter cartridge 310, and is suitable for improving the sealing performance between the filter cartridge 310 and the separator 120.

[0097] In some embodiments, combined with Figure 2 and Figure 4 The cup body 110 includes a first sidewall 1101 and a second sidewall 1102 that are opposite each other along the second direction (i.e., the y direction). The air inlet 113 and the air outlet 114 are both located on the first sidewall 1101. The dust baffle 130 is located at the corner where the separator 120 and the first sidewall 1101 are connected and is located on one side of the ash storage chamber 1111. The dust baffle 130 is located adjacent to the ash throwing port 1201 and has a filter hole 131.

[0098] The dust baffle 130 can be a plate-shaped structure installed at the connection between the side wall of the ash storage chamber 1111 and the separator 120. The air filter hole 131 is opened on the dust baffle 130. Optionally, the air filter hole 131 can be a circular hole of 0.5-2 mm, which can ensure airflow while maintaining the blocking effect.

[0099] During the process of airflow from the cyclone chamber 1112 to the air outlet 114, the filter element 330 performs secondary filtration on the airflow passing through the connection port, intercepting dust particles that may escape from the ash storage chamber 1111 to the cyclone chamber 1112, and can effectively block the reverse movement of light debris such as hair under airflow disturbance.

[0100] By designing the filter element 330 and opening the air filter hole 131, the synergistic effect of physical blocking and hole size control can be achieved, ensuring normal ventilation volume while achieving unidirectional dust and air separation, improving the interception efficiency of fine particles, and avoiding the phenomenon of dust re-flying due to airflow disturbance.

[0101] In some embodiments, combined with Figure 1 , Figure 2 and Figure 5 The cover assembly 200 includes an upper cover support 210 and an upper cover body 220. The upper cover support 210 is adapted to block the ash outlet 112. A guide surface 201 is formed on the upper cover support 210, and the upper cover body 220 is placed on the upper cover support 210.

[0102] The upper cover support 210 can be a rigid support component for sealing the dust outlet 112 at the top of the dust cup 100. Optionally, the upper cover support 210 may be provided with an elastic sealing ring on the side facing the cup body 110, which is suitable for forming an interference fit with the cup body 110. The upper cover body 220 can be a detachable protective component covering the outside of the upper cover support 210.

[0103] The separate design of the upper cover support 210 and the upper cover body 220 allows the upper cover body 220 to be disassembled separately during maintenance and cleaning, avoiding frequent disassembly and assembly, improving cleaning convenience, and reducing maintenance difficulty while ensuring performance. In addition, the upper cover support 210 has a guide surface 201 to improve dust and gas separation efficiency.

[0104] Optionally, the first seal 211 may surround the upper cover support 210 to improve the seal between the cover assembly 200 and the dust cup 100.

[0105] Optionally, the cover assembly 200 may also include a first latch 230 and a second latch 240. Both the first latch 230 and the second latch 240 may be provided on either the upper cover support 210 or the upper cover body 220. The first latch 230 may be used to remove the dust cup 100 from the device body, and the second latch 240 may be used to remove the cover assembly 200 from the dust cup 100.

[0106] The first latch 230 can be disposed on the outer surface of the upper cover body 220 for user pressing operation. The first latch 230 can be connected to the dust cup 100 release mechanism. When the user presses the first latch 230, it can drive the dust cup 100 release mechanism to operate, thereby removing the dust cup 100 from the device body.

[0107] The second latch 240 may be provided on the outer surface of the upper cover support 210, and the dust cup 100 may be provided with a latch engagement part. The second latch 240 may engage with the latch engagement part to fix the cover assembly 200 on the dust cup 100. When it is necessary to remove the cover assembly 200 from the dust cup 100, the user can press or move the second latch 240 to disengage the second latch 240 from the latch engagement part on the dust cup 100, thereby removing the cover assembly 200 from the dust cup 100.

[0108] In addition, this application also provides a cleaning device, which includes, but is not limited to, a mite remover, or a vacuum cleaner.

[0109] The cleaning equipment may include the equipment body and the aforementioned dust collection device 10. Optionally, the dust collection device 10 may be detachably installed on the equipment body, so that the user can easily remove the dust collection device 10 for emptying or cleaning, which helps to improve the ease of use and maintenance efficiency of the cleaning equipment.

[0110] When it is necessary to clean and remove dust from the dust collection device 10, the first latch 230 can be pressed to detach the dust collection device 10 from the equipment body, and the second latch 240 can be pressed to detach the cover assembly 200 and the dust cup 100, so that the ash outlet 112 and the ash discharge port can be opened at the same time. In this way, the ash storage chamber 1111 and the cyclone chamber 1112 can be cleaned at the same time. The dust and impurities collected in the ash storage chamber 1111 can be sucked out, and the hair adhering to the inner wall of the cyclone chamber 1112, the hair wrapped around the outer wall of the filter assembly 300, and the foreign objects blocking the filter holes 311 can be removed.

[0111] Thus, the cleaning equipment of this embodiment can clean the dust collection chamber 1111 and the cyclone chamber 1112 of the dust collection device 10. It can remove the dust and impurities collected in the dust collection chamber 1111, and remove the hair and foreign objects that are adhered to the inner wall of the cyclone chamber 1112, wrapped around the outer wall of the filter assembly 300, blocked in the filter hole 311, and blocked in the air filter hole 131, so as to ensure the suction power of the cleaning equipment and thus ensure the cleaning effect of the cleaning equipment.
