Description

Technical Field

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

[0002] Vacuum cleaners and other cleaning equipment are increasingly used in people's daily lives. Vacuum cleaners mainly clean the floor by using a floor brush and use a suction motor to generate negative pressure to suck dust into a dust collection device, which then separates dust and air and collects dust and debris.

[0003] However, some vacuum cleaner models 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 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, cleaning equipment and cleaning system that can easily remove hair and foreign objects in the cyclone chamber, avoid filter clogging and ensure the suction power of the cleaning equipment.

[0005] In a first aspect, this application provides a dust collection device for cleaning equipment, comprising: a dust cup having an air inlet, an air outlet, and an openable / closable ash outlet; a dust-air separator disposed within the inner cavity of the dust cup, the dust-air separator dividing the inner cavity of the dust cup into an ash storage chamber and a cyclone chamber, the dust-air separator having an ash-throwing port for connecting the ash storage chamber and the cyclone chamber, the cyclone chamber being connected to the air inlet; a filter assembly disposed within the dust cup, the filter assembly including a filter cylinder extending into the cyclone chamber to separate dust and air in the airflow entering the cyclone chamber, at least a portion of the structure of the filter cylinder being deformable; the ash outlet being adapted to connect to a cleaning base station, and when the ash outlet is connected to the cleaning base station, the filter cylinder being adapted to deform under the airflow driven by at least one of the cleaning base station and the cleaning equipment.

[0006] The dust collection device of this application, during the operation of the cleaning equipment, when dust, hair, and other debris sucked in by the floor brush device enters the cyclone chamber through the air inlet with the airflow, it is subjected to the combined effects of the centrifugal force of the cyclone and the gravity of the debris itself. The centrifugal force causes the debris to spiral along the inner wall of the cyclone chamber, reducing the accumulation of debris on the surface of the filter cartridge within the cyclone chamber and mitigating the problem of filter pore clogging. The dust and other debris, under the influence of their own gravity, descend within the cyclone chamber. When the dust and debris reach the ash-throwing port under the combined action of gravity and centrifugal force, they are thrown into the ash-storage chamber. During cleaning of the dust collection device by the cleaning base station, when the filter cartridge deforms, hair or other impurities adhering to or entangled on the outer wall of the filter cartridge fall off and are sucked into the cleaning base station, thus keeping the dust collection device clean and ensuring smooth airflow inside the dust collection device, guaranteeing the suction power and cleaning effect of the cleaning equipment.

[0007] In some embodiments, the filter cylinder has an internal filter chamber that is connected to the air inlet, and the side wall of the filter cylinder has a plurality of filter holes that connect the cyclone chamber and the filter chamber.

[0008] The filter cartridge is used for preliminary filtration, blocking dust and debris from entering the cyclone chamber. It can effectively remove larger particles. After being filtered by the filter cartridge, the air enters the filter chamber through the filter holes. Hair, particles, and dust in the air spiral within the cyclone chamber and are eventually discharged into the ash storage chamber through the ash discharge port. The filter chamber is a space inside the filter cartridge used to contain the filtered air. The filter holes are the channels between the filter chamber and the cyclone chamber, allowing air to pass through while blocking larger particles, thus achieving the filtration effect.

[0009] In some embodiments, the filter cartridge includes: a support body connected to at least one of the dust cup and the dust-air separator, the support body defining a portion of the structure of the filter chamber; and a flexible body connected to one end of the support body away from the air outlet, the flexible body defining another portion of the structure of the filter chamber, the flexible body being adapted to deform under the action of the cleaning station.

[0010] In this way, the support body facilitates the installation of the filter cartridge and also provides installation support for the flexible body. The flexible body can deform to facilitate the removal and suction of hair and foreign objects adhering to the outer wall of the filter cartridge.

[0011] In some embodiments, one of the support body and the flexible body is provided with a connecting structure, and the other is provided with a connecting and mating structure, and the support body and the flexible body are connected through the connecting structure and the connecting and mating structure.

[0012] In this way, the support and the flexible body can be fixed, preventing the flexible body from falling off the support when it deforms.

[0013] In some embodiments, the support body has a connecting ring at one end facing the flexible body, and the connecting ring constitutes the connecting structure; the flexible body has a mating ring at one end facing the support body, and the mating ring constitutes the connecting mating structure, and the connecting ring and the mating ring are nested together.

[0014] Thus, the combination of the support and the flexible body is relatively simple, and easy to manufacture and assemble.

[0015] In some embodiments, the flexible body comprises a silicone component. Thus, the flexible sealing component exhibits good flexibility, and the material is widely available and inexpensive.

[0016] In some embodiments, the dust collection device further includes: a flexible shielding member disposed at the dust discharge port and partially blocking the dust discharge port; the dust collection device is configured such that, under the suction force of the cleaning equipment, the flexible shielding member partially blocks the dust discharge port, and, under the suction force of the cleaning base station, the flexible shielding member deforms to increase the area of ​​the dust discharge port.

[0017] Thus, when the cleaning equipment is working, the flexible shielding part blocks part of the dust throwing port, so that the airflow has a longer time to flow through the cyclone cavity and the dust and gas are separated more fully; while when cleaning the dust collection device of the base station, the area of ​​the dust throwing port is increased, so that dust, hair and other foreign objects in the cyclone cavity can more easily pass through the dust throwing port and reach the cleaning base station through the dust storage cavity and the dust outlet.

[0018] In some embodiments, the dust-air separation component includes a side partition and a bottom partition. The side partition is connected between the inner walls of opposite sides of the dust cup, and the bottom partition is connected to the side partition. The bottom partition covers the end of the cyclone chamber away from the air outlet, and the dust discharge port is opened on the side partition.

[0019] The side baffles, through their own barrier function, divide the hollow cavity inside the dust cup into adjacent ash storage chambers and cyclone chambers. The side baffles guide airflow to create a rotating motion within the cyclone chambers. Ash ejection ports are located within the side baffles, facilitating the transfer of dust and other debris separated from the cyclone chambers into the ash storage chambers. The bottom baffle seals the end of the cyclone chamber furthest from the outlet, ensuring an effective rotational path for airflow within the cyclone chamber and increasing the separation efficiency of dust and other debris from the air.

[0020] In some embodiments, the ash-throwing port and the air inlet are located on different side walls of the cyclone cavity, and the angle between the central axis of the ash-throwing port and the central axis of the air inlet is 80°-120°.

[0021] In this way, dust and other debris entering the cyclone chamber from the air inlet can be thrown against the inner wall of the cyclone chamber by the centrifugal force of the cyclone, and discharged into the ash storage chamber through the ash throwing port.

[0022] In some embodiments, the top of the filter cartridge has a connecting portion, which is connected to the inner wall of the dust cup. The interior of the connecting portion forms an air passage cavity, which connects the filter cavity and the air outlet. The dust-air separation component further includes a platform portion, which is connected to the end of the side partition away from the bottom partition. The bottom end of the connecting portion abuts against the platform portion.

[0023] In some embodiments, the filtering assembly further includes at least one first filter element disposed within the air passage cavity.

[0024] By setting up a first filter element, the airflow that has been initially filtered by the filter cartridge can be filtered a second time, thereby reducing the risk of impurities being sucked into the suction motor.

[0025] In some embodiments, the dust collection device further includes a flow guide, which is disposed between the first filter and the filter cylinder. The flow guide includes a first flow guide plate and a second flow guide plate connected to the edge of the first flow guide plate. The center of the first flow guide plate protrudes into the filter cavity, and the second flow guide plate extends horizontally along the periphery of the first flow guide plate within the air passage cavity.

[0026] The airflow guide serves to disperse and guide the airflow, causing the airflow from inside the filter cartridge to the first filter element to be dispersed, increasing the airflow path, preventing the airflow in the filter chamber from vertically impacting the first filter element, reducing the direct adhesion of dust and other impurities to the first filter element, and solving the problems of the first filter element being deformed by airflow impact, being easily blocked, and generating noise.

[0027] In some embodiments, the dust collection device further includes a dust baffle, which is movably disposed at the air inlet and configured to open and close the air inlet.

[0028] By closing the air inlet with a dust baffle, dust and debris inside the cyclone chamber are prevented from falling out of the air inlet. This helps to avoid secondary pollution when the cleaning equipment is turned off or moved, and also protects the internal components of the cleaning equipment from the intrusion of dust and debris from the external environment, thus extending the service life of the cleaning equipment.

[0029] Secondly, this application provides a cleaning device, including a main body and the aforementioned dust collection device.

[0030] The cleaning equipment of this application, by setting the aforementioned dust collection device, can not only remove the dust and impurities collected in the dust storage chamber of the dust collection device, but also remove hair and foreign objects that adhere to the inner wall of the cyclone chamber, wrap around the outer wall of the filter component, and block the filter holes, thereby ensuring the suction power and cleaning effect of the cleaning equipment.

[0031] Thirdly, this application provides a cleaning system, comprising: the cleaning equipment described above; and a cleaning base station adapted to be connected to the dust outlet of the dust collection device of the cleaning equipment, for cleaning the dust collection device.

[0032] The cleaning system of this application can use the cleaning base station to clean the dust storage chamber and cyclone chamber of the dust collection device. It can not only remove the dust and impurities collected in the dust storage chamber, but also remove hair and foreign objects that adhere to the inner wall of the cyclone chamber, wrap around the outer wall of the filter component, and block the filter holes, thus ensuring the suction power of the cleaning equipment and ensuring the cleaning effect of the cleaning equipment.

[0060] 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.

[0061] Vacuum cleaners and other cleaning equipment are increasingly used in people's daily lives. Vacuum cleaners mainly clean floors with a floor brush and use a suction motor to create negative pressure to suck dust into a dust collection device, which then separates the dust and air and collects the dust and debris. However, some vacuum cleaner models are prone to problems when dealing with long hair and large particles, such as hair and 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 clogged filter holes can also reduce the vacuum cleaner's suction power, making it difficult to suck up hair, dust, and mites, thus affecting the cleaning effect.

[0062] In view of this, this application provides a dust collection device, a cleaning equipment, and a cleaning system. When cleaning the dust collection device, the dust in the dust storage chamber can be emptied through the dust outlet, and the hair wrapped around and adhered to the inner wall of the cyclone chamber, the outer wall of the filter cartridge, and the filter holes can be removed through the dust discharge outlet. This ensures smooth airflow inside the dust collection device, allows the cleaning equipment to maintain stable suction, ensures cleaning efficiency and effectiveness, and reduces the frequency of filter cartridge cleaning by the user.

[0063] The cleaning device 100 in this application embodiment includes, but is not limited to, a vacuum cleaner. (See reference...) Figure 6 and Figure 7 As shown, the cleaning equipment 100 may include the equipment body 2 and the dust collection device 1 described above.

[0064] The main body 2 of the device may include a floor brush device and a main unit. The main unit includes a body 201 and a drive component 202. The drive component 202 is disposed on the body 201 and has a nozzle. The dust collection device 1 is detachably disposed on the body 201. The bottom end of the body 201 is connected to the floor brush device. The body 201 has a suction channel. The air inlet 11 of the dust collection device 1 is connected to the outlet end of the suction channel, and the nozzle is connected to the air outlet 12 of the dust collection device 1. The floor brush device has a suction port. The floor brush device can discharge dust, hair, or other debris on the surface to be cleaned into the dust collection device 1 by passing through the suction port, the suction channel, and the air inlet 11 in sequence. The drive component 202 may be a suction motor to provide suction power.

[0065] The dust collection device 1 is detachably mounted on the body 201, so that users can easily remove the dust collection device 1 for emptying or cleaning, which helps to improve the ease of use and maintenance efficiency of the cleaning equipment 100.

[0066] refer to Figures 1-3 As shown, the dust collection device 1 in this embodiment may include: a dust cup 10, a dust-gas separator 20, and a filter assembly 30.

[0067] The dust cup 10 has a hollow interior, and its cross-section perpendicular to the axis can be circular, elliptical, or any other arbitrary shape. The dust cup 10 has an air inlet 11, an air outlet 12, and a dust outlet 16. The air inlet 11 can be connected to the floor brush device of the cleaning equipment 100. The air outlet 12 can be connected to the suction motor of the cleaning equipment 100, and the suction motor applies negative pressure to the interior cavity of the dust cup 10 through the air outlet 12.

[0068] The ash outlet 16 is openable and closable. It can be opened after the cleaning device 100 has finished cleaning to facilitate the removal of dust and debris collected in the dust cup 10. Optionally, the ash outlet 16 is suitable for connection to the cleaning base station 200, allowing the dust collection device 1 of this embodiment to remove internally stored dust and impurities through the cleaning base station 200. Optionally, a cover plate 60 for opening and closing the ash outlet 16 can be provided at the ash outlet 16. For example, the cover plate 60 can be pivotally connected to the periphery of the ash outlet 16, or it can be snap-fitted, or other connection methods may also be used.

[0069] The dust-gas separator 20 is disposed in the inner cavity of the dust cup 10. The dust-gas separator 20 can divide the inner cavity of the dust cup 10 into a dust storage chamber 13 and a cyclone chamber 14. The dust-gas separator 20 has a dust throwing port 21, which connects the dust storage chamber 13 and the cyclone chamber 14. The air inlet 11 is located on the side wall of the dust cup 10 and is connected to the cyclone chamber 14. Along the axial direction of the dust cup 10, the air inlet 11 is closer to the air outlet 12 than the dust throwing port 21.

[0070] Since the dust-air separator 20 divides the interior of the dust cup 10 into a dust storage chamber 13 and a cyclone chamber 14, and a dust-throwing port 21 is provided in the dust-air separator 20, the dust-throwing port 21 connects the dust storage chamber 13 and the cyclone chamber 14, the air inlet 11 is located on the side wall of the dust cup 10, and along the axial direction of the dust cup 10, the air inlet 11 is closer to the air outlet 12 than the dust-throwing port 21. In use, air enters the interior of the dust cup 10 from the air inlet 11 and finally leaves the dust cup 10 from the air outlet 12.

[0071] The filter assembly 30 can be disposed within the dust cup 10. The filter assembly 30 includes a filter cylinder 31 extending into the cyclone chamber 14 to separate dust and air in the airflow entering the cyclone chamber 14. The filter cylinder 31 is spaced apart from the inner wall (including the side wall and bottom wall) of the cyclone chamber 14 to ensure smooth airflow. After the airflow enters the cyclone chamber 14, it can form a spiral airflow around the filter assembly 30, thereby throwing the dust and impurities filtered by the filter assembly 30 from the cyclone chamber 14 into the dust storage chamber 13 for storage through the dust throwing port 21. The filtered air can then flow to the air outlet 12 after passing through the filter assembly 30.

[0072] At least a portion of the structure of the filter cartridge 31 is deformable. For example, a portion of the filter cartridge 31 may be deformable along its circumferential direction, or a portion of the filter cartridge 31 may be deformable along its axial direction. Alternatively, the entire filter cartridge 31 may be deformable. When the ash outlet 16 is connected to the cleaning base station 200, the filter cartridge 31 is adapted to deform under the airflow driven by at least one of the cleaning base station 200 and the cleaning device 100. When the cleaning base station 200 operates, causing the filter cartridge 31 to deform, hair or other impurities adhering to or entangled on the outer wall of the filter cartridge 31 can be detached and sucked into the cleaning base station 200, preventing the filter holes 312 from becoming clogged. This ensures smooth airflow inside the dust collection device 1 and guarantees the suction power and cleaning effect of the cleaning device 100.

[0073] For example, the cleaning base station 200 may be equipped with a dust removal motor. When the dust removal motor is running, it generates negative pressure in the internal air duct of the cleaning base station 200. When the dust outlet 16 of the dust collection device 1 is connected to the cleaning base station 200, the negative pressure generated by the dust removal motor drives the filter cylinder 31 to deform, so that the hair or other impurities that are adhered to or wrapped around the outer wall of the filter cylinder 31 can be detached and sucked into the cleaning base station 200.

[0074] Alternatively, the suction motor of the cleaning device 100 can be rotated in an adjustable direction. When the cleaning device 100 is cleaning normally, the suction motor rotates in the first rotation direction to generate suction force. When the dust outlet 16 of the dust collection device 1 is connected to the cleaning base station 200, the suction motor of the cleaning device 100 reverses in the second rotation direction to generate a pushing force on the filter cartridge 31, so that the filter cartridge 31 is deformed, and the hair or other impurities that are adhered to or wrapped around the outer wall of the filter cartridge 31 can be detached and sucked into the cleaning base station 200. The first rotation direction and the second rotation direction are opposite.

[0075] Alternatively, an air duct switching device can be installed on the cleaning equipment 100. When the dust outlet 16 of the dust collection device 1 is connected to the cleaning base station 200, the air duct of the cleaning equipment 100 is connected to the internal air duct of the cleaning base station 200 through the air duct switching device. The suction force generated by the suction motor of the cleaning equipment 100 acts on the filter cartridge 31 from one side of the cleaning base station 200, causing the filter cartridge 31 to deform. This allows hair or other impurities that are adhered to or wrapped around the outer wall of the filter cartridge 31 to fall off and be sucked into the cleaning base station 200.

[0076] Optionally, the filter cartridge 31 can remain in its original state while the cleaning equipment 100 is performing cleaning work, so as to efficiently filter and separate gas and dust impurities.

[0077] In this embodiment of the dust collection device 1, when the cleaning equipment 100 is working, the dust, hair and other debris sucked in by the floor brush device enter the cyclone chamber 14 from the air inlet 11 with the airflow. They are subjected to the combined effects of the centrifugal force of the cyclone and the gravity of the debris itself. The centrifugal force of the cyclone causes the debris to spiral along the inner wall of the cyclone chamber 14, reducing the accumulation of debris on the surface of the filter cartridge 31 in the cyclone chamber 14 and reducing the problem of clogging of the filter holes 312 of the filter cartridge 31. The dust and other debris are subjected to their own gravity and will move downward in the cyclone chamber 14. When the dust and debris move to the position of the ash throwing port 21 under the combined action of gravity and centrifugal force, the debris is thrown from the ash throwing port 21 into the ash storage chamber 13. When the cleaning base station 200 cleans the dust collection device 1, the filter cartridge 31 deforms, causing hair or other impurities that are adhered to or wrapped around the outer wall of the filter cartridge 31 to fall off and be sucked into the cleaning base station 200, preventing the filter holes 312 from becoming clogged, thus ensuring smooth airflow inside the dust collection device 1 and guaranteeing the suction power and cleaning effect of the cleaning equipment 100.

[0078] In one possible implementation, the dust cup 10 and the dust-gas separator 20 can be an integrally connected structure, which helps to improve the structural strength of the connection.

[0079] 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 13 directly, facilitating timely cleaning.

[0080] In one possible implementation, the ash discharge port 21 is, but is not limited to, rectangular or circular shapes. The air inlet 11 is, but is not limited to, rectangular or trapezoidal shapes.

[0081] In one possible implementation, the dust ejection port 21 and the air inlet 11 are located on different sidewalls of the cyclone chamber 14, with an angle between the central axis of the dust ejection port 21 and the central axis of the air inlet 11. This structure helps to optimize the airflow path and more effectively utilize the cyclone effect to separate dust particles from the air.

[0082] In one possible implementation, the filter cylinder 31 forms a filter cavity 311 inside, which is connected to the air outlet 12. The side wall of the filter cylinder 31 is provided with a plurality of filter holes 312 that connect the cyclone cavity 14 and the filter cavity 311.

[0083] The filter cartridge 31 is used for preliminary filtration to block dust and debris from entering the cyclone chamber 14. It can effectively remove larger particles. After being filtered by the filter cartridge 31, the air enters the filter chamber 311 through the filter holes 312. Hair, particles, and dust in the air spiral within the cyclone chamber 14 and are finally discharged into the ash storage chamber 13 through the ash discharge port 21. The filter chamber 311 is a space inside the filter cartridge 31 used to contain the filtered air. The filter holes 312 are the channels between the filter chamber 311 and the cyclone chamber 14, allowing air to pass through while blocking larger particles, thus achieving the filtration effect.

[0084] In one possible implementation, the number of filter holes 312 and the inner diameter of the filter holes 312 are not specifically limited here. Multiple filter holes 312 can be arranged along the periphery of the filter cylinder 31. The design of multiple filter holes 312 increases the effective filtration area, thereby improving the filtration efficiency and making the discharged air cleaner.

[0085] In one possible implementation, along the axial direction of the dust cup 10, the outer diameter of the filter cartridge 31 gradually decreases from the top to the bottom. This structure makes the filter cartridge 31 roughly a conical tube sealed at one end. Hair and other debris wrapped around the outer wall of the filter cartridge 31 can leave the outer wall of the filter cartridge 31 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 31.

[0086] In one possible implementation, the longitudinal section of the filter cartridge 31 is U-shaped.

[0087] The bottom of the filter cartridge 31 is closed. The closed structure can prevent airflow from entering the filter chamber 311 directly without being filtered by the filter cartridge 31, effectively controlling the airflow path, ensuring that all air is filtered by the filter cartridge 31, effectively protecting other filter structures downstream of the airflow path, and improving the dust removal effect.

[0088] In some embodiments, reference Figure 1 and Figure 4 The filter cartridge 31 may include a support 313 and a flexible body 314. The support 313 is a rigid component, such as a plastic or metal component. The support 313 is connected to at least one of the dust cup 10 and the dust-air separation component 20, defining a portion of the structure of the filter chamber 311. The flexible body 314 is connected to the end of the support 313 away from the air outlet 12. For example, the support 313 and the flexible body 314 are distributed along the axial direction of the dust cup 10 at the air outlet 12, and the flexible body 314 is closer to the dust outlet 16 in the airflow path. The flexible body 314 defines another portion of the structure of the filter chamber 311 and is adapted to deform under the action of the cleaning station 200.

[0089] Thus, the support 313 facilitates the installation of the filter cartridge 31 and also provides installation support for the flexible body 314. The flexible body 314 can deform to facilitate the removal and absorption of hair and foreign objects adhering to the outer wall of the filter cartridge 31.

[0090] Optionally, the filter hole 312 is disposed on at least one of the flexible body 314 and the support body 313. For example, only the support body 313 may have the filter hole 312, or only the flexible body 314 may have the filter hole 312, or both the support body 313 and the flexible body 314 may have the filter hole 312. In this way, the flexible body 314 and / or the support body 313 with the filter hole 312 can filter the airflow.

[0091] In some embodiments, one of the support body 313 and the flexible body 314 is provided with a connecting structure, and the other is provided with a connecting mating structure. For example, the connecting structure can be a snap-fit ​​structure, a plug-in structure, a bolt connection structure, etc., and the connecting mating structure is adapted to the connecting structure. The support body 313 and the flexible body 314 are connected through the connecting structure and the connecting mating structure. The specific construction of the connecting structure and the connecting mating structure can be reasonably selected according to actual needs, and this embodiment does not impose any restrictions on this. In this way, the support body 313 and the flexible body 314 can be fixed, preventing the flexible body 314 from falling off the support body 313 when it deforms.

[0092] In some embodiments, the end of the support 313 facing the flexible body 314 is provided with a connecting ring, which constitutes a connecting structure; the end of the flexible body 314 facing the support 313 is provided with a mating ring, which constitutes a connecting and mating structure. The connecting ring and the mating ring are nested together. For example, the connecting ring may be located inside the mating ring, or the mating ring may be located inside the connecting ring. In this way, the mating method between the support 313 and the flexible body 314 is relatively simple and easy to manufacture and assemble.

[0093] To improve the connection stability between the support 313 and the flexible body 314, the connecting ring and the mating ring can be glued together; alternatively, a locking hole can be provided on the connecting ring, and a locking post can be provided on the mating ring, with the locking post inserted into the locking hole. Of course, this application does not limit this, and the mating form of the connecting ring and the mating ring can be reasonably set according to actual needs. This further enhances the connection stability between the flexible body 314 and the support 313.

[0094] In some embodiments, the flexible body 314 includes a silicone component. Thus, the flexible sealing component exhibits good flexibility, and the material is widely available and inexpensive.

[0095] In some embodiments, the dust collection device 1 may further include a flexible shielding member 25, which is disposed at the dust discharge port 21 and partially blocks the dust discharge port 21. The dust collection device 1 is configured such that, under the suction force of the cleaning device 100, the flexible shielding member 25 partially blocks the dust discharge port 21, so that the airflow has a longer flow time in the cyclone chamber 14 and more fully separates dust and gas. In addition, the dust collection device 1 is also configured such that, under the suction force of the cleaning base station 200, the flexible shielding member 25 deforms to increase the area of ​​the dust discharge port 21. Thus, when cleaning the dust collection device 1, the area of ​​the dust discharge port 21 increases, making it easier for dust, hair, and other foreign objects in the cyclone chamber 14 to pass through the dust discharge port 21 and reach the cleaning base station 200 via the dust storage chamber 13 and the dust outlet 16.

[0096] In one possible implementation, the angle between the central axis of the ash-throwing port 21 and the central axis of the air inlet 11 can be 80°-120°, for example, 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 14 from the air inlet 11 towards the inner wall of the cyclone chamber 14, and then discharge them into the ash storage chamber 13 through the ash-throwing port 21. Here, the central axis of the ash-throwing port 21 refers to a reference line passing through the center of the ash-throwing port 21, and the central axis of the air inlet 11 refers to a reference line passing through the center of the air inlet 11.

[0097] In one possible implementation, the dust-air separator 20 includes a side partition 22 and a bottom partition 23. The side partition 22 can be connected between the inner walls of opposite sides of the dust cup 10, and the bottom partition 23 is connected to the side partition 22 and covers the end of the cyclone chamber 14 away from the air outlet 12. The dust discharge port 21 is opened on the side partition 22. For example, the dust discharge port 21 can be opened on the end of the side partition 22 facing the bottom partition 23, such that part of the bottom partition 23 forms the inner wall surface of the dust discharge port 21.

[0098] This structure ensures that the bottom of the ash discharge port 21 is flush with the bottom partition plate 23, which facilitates the smooth discharge of dust and other debris separated in the cyclone chamber 14 through the ash discharge port 21, ensuring the smooth flow of dust and other debris from the ash discharge port 21 into the ash storage chamber 13.

[0099] The side partition 22, through its own barrier function, divides the hollow cavity inside the dust cup 10 into an adjacent ash storage chamber 13 and a cyclone chamber 14. The side partition 22 can guide the airflow to form a rotational motion within the cyclone chamber 14. The ash throwing port 21 is opened inside the side partition 22, which helps the dust and other debris separated from the cyclone chamber 14 to enter the ash storage chamber 13 through the ash throwing port 21.

[0100] The bottom baffle 23 is used to close the end of the cyclone cavity 14 away from the air outlet 12, ensuring that the airflow forms an effective rotation path in the cyclone cavity 14, which helps to increase the separation efficiency of dust and other debris from the air.

[0101] In one possible implementation, the side partition 22 is arc-shaped, making the cyclone cavity 14 nearly cylindrical.

[0102] In one possible implementation, the bottom partition 23 is in the form of a horizontal panel.

[0103] In some embodiments, the air outlet 12 is located at the top of the dust cup 10. For example, the top of the dust cup 10 is open to form the air outlet 12, so that the air outlet 12 can communicate with the suction motor on the upper side of the dust collection device 1. The ash outlet 16 is located at the bottom of the dust cup 10. In this case, the cover plate 60 can serve as the bottom cover of the dust cup 10. The bottom partition plate 23 and the cover plate 60 are arranged at intervals along the height direction of the dust cup 10, that is, a part of the ash storage chamber 13 and the cyclone chamber 14 are separated by the bottom partition plate 23, and a part of the ash storage chamber 13 is located below the cyclone chamber 14.

[0104] For example, the cover plate 60 and the air outlet 12 are located at opposite ends of the dust cup 10, and at opposite ends of the dust cup 10 in the axial direction. The air outlet 12 is used to discharge filtered air, which helps to ensure that the air leaves the dust collection device 1 smoothly through the air outlet 12, reducing air resistance and improving overall efficiency. The cover plate 60 can be opened to empty the dust accumulated in the ash storage chamber 13, facilitating maintenance and cleaning. With this design, users can easily open the ash storage chamber 13 to empty the collected dust and particles, keeping the cleaning equipment 100 clean and operating efficiently.

[0105] Optionally, one side of the cover 60 is hinged to the dust cup 10, and the other side of the cover 60 is mechanically locked to the dust cup 10.

[0106] Optionally, the dust collection device 1 also includes an operation button 15, which is disposed on the dust cup 10. The operation button 15 includes a locking part 152, and the cover plate 60 has a hook part 61. The operation button 15 is movably disposed on the outer wall surface of the dust cup 10 so that the locking part 152 extends into the hook part 61.

[0107] The user operates the control button 15 to lock and release the cover 60. The locking part 152 extends into the hook part 61 to lock the cover 60, making it difficult to open and improving the stability of the cover 60's closure, thus preventing dust leakage from the ash storage chamber 13. When the locking part 152 disengages from the hook part 61, the cover 60 is released, allowing it to be opened and enabling the cleaning of dust and debris from the ash storage chamber 13.

[0108] In one possible implementation, the locking part 152 has a latching protrusion, and the stop hook part 61 is typically a recessed structure. The stop hook part 61 is designed to accommodate the size and shape of the latching protrusion to ensure that the latching protrusion can be smoothly inserted into the stop hook part 61 and remain stable. When the latching protrusion extends into the stop hook part 61, the inner wall of the stop hook part 61 comes into close contact with the outer surface of the latching protrusion, achieving mechanical locking and ensuring that the cover 60 will not be easily opened during use.

[0109] In one possible implementation, the operating button 15 further includes a pressing part 151 and a rotating part 153. The pressing part 151 is connected to one end of the locking part 152 relative to the hook part 61, and the rotating part 153 is disposed at the connection position of the pressing part 151 and the locking part 152. The operating button 15 is rotatably disposed on the dust cup 10 via the rotating part 153.

[0110] When in use, the user presses the pressing part 151 of the operation button 15, causing the operation button 15 to rotate around the central axis of the rotating shaft part 153. The pressing part 151 moves toward the inside of the dust cup 10, and the locking part 152 moves away from the dust cup 10, thereby causing the locking part 152 to disengage from the hook part 61 and unlocking the cover plate 60.

[0111] In one possible implementation, the pivot portion 153 is also provided with a torsion spring, which is used to reset the operation button 15 when the pressing portion 151 is released, so as to ensure that the locking portion 152 can stably cooperate with the stop hook portion 61 to achieve the locking effect on the cover plate 60.

[0112] In one possible implementation, a sealing ring 62 is provided between the end of the cover plate 60 and the end of the dust cup 10 to prevent dust from leaking between the end of the cover plate 60 and the end of the dust cup 10.

[0113] In one possible implementation method, refer to Figure 1 As shown, the top of the filter cartridge 31 has a connecting portion 32, which is connected to the inner wall of the dust cup 10. The interior of the connecting portion 32 forms an air passage cavity 321, which connects the filter cavity 311 and the air outlet 12. The connecting portion 32 is used to fix the filter cartridge 31 to the inner wall of the dust cup 10, ensuring the stability of the filter cartridge 31 inside the dust cup 10.

[0114] In one possible implementation method, refer to Figure 1 and Figure 3 As shown, the dust-air separator 20 also includes a platform section 24, which is connected to the end of the side partition 22 away from the bottom partition 23, and the bottom end of the connecting part 32 abuts against the platform section 24. The platform section 24 serves to support the connecting part 32 and improve the stability of the filter cartridge 31.

[0115] In one possible implementation, the connection 32 and the inner wall of the dust cup 10 can be connected by a snap-fit ​​or an interference fit.

[0116] In one possible implementation, the connecting part 32 may be basin-shaped, and the filter cylinder 31 and the connecting part 32 may be an integral structure connected as one piece, or they may be separate structures.

[0117] In one possible implementation method, refer to Figure 1 As shown, the filter assembly 30 also includes at least one first filter element 40, which is disposed within the air passage cavity 321. The first filter element 40 can perform secondary filtration on the airflow after the initial filtration by the filter cartridge 31, thereby reducing the risk of impurities being sucked into the suction motor.

[0118] In one possible implementation, the number of first filter elements 40 can be two or more to improve the filtration effect. The multiple first filter elements 40 can be made of the same material or different materials.

[0119] In one possible implementation, the filter assembly 30 includes two first filter elements 40, namely a sponge and a HEPA filter, wherein the sponge is located on the side closer to the filter cartridge 31 and the HEPA filter is located on the side closer to the air outlet 12. The HEPA filter can filter out fine dust particles of 0.3μm, making the exhaust air cleaner.

[0120] In one possible implementation, the dust collection device 1 further includes a flow guide 50 disposed between the first filter element 40 and the filter cartridge 31. The flow guide 50 includes a first flow guide plate 51 and a second flow guide plate 52 connected to the edge of the first flow guide plate 51. The center of the first flow guide plate 51 protrudes into the filter cavity 311, and the second flow guide plate 52 extends horizontally along the periphery of the first flow guide plate 51 within the air passage cavity 321.

[0121] The guide element 50 serves to disperse and guide the airflow, causing the airflow from the inside of the filter cylinder 31 to the first filter element 40 to be dispersed, increasing the airflow path, preventing the airflow in the filter chamber 311 from vertically impacting the first filter element 40, reducing the direct adhesion of dust and other impurities to the first filter element 40, and solving the problems of the first filter element 40 being deformed by airflow impact, being easily blocked, and generating noise.

[0122] In one possible implementation, the first guide plate 51 has a "V"-shaped cross-section, with its center protruding into the filter cavity 311, guiding airflow between the periphery of the first guide plate 51 and the inner wall of the filter cavity 311. When the airflow in the filter cavity 311 encounters the first guide plate 51, the first guide plate 51 can change the direction of the airflow, causing the airflow to disperse. This disperses and buffers the airflow before it enters the first filter element 40 from the filter cavity 311, rather than directly impacting the first filter element 40 at high speed and high pressure. This helps reduce wear and noise problems of the first filter element 40, ensuring the service life of the first filter element 40 and reducing the frequency of maintenance and replacement of the first filter element 40.

[0123] The second guide plate 52 is connected to the edge of the first guide plate 51 and is horizontally extended along the periphery of the first guide plate 51 within the air passage cavity 321. The second guide plate 52 is used to further guide the airflow, ensuring that the airflow flows along a longer path before entering the first filter element 40, so that the airflow has more opportunities to contact the first filter element 40, which is beneficial for the first filter element 40 to capture more dust and other impurity particles.

[0124] In one possible implementation method, refer to Figure 2 and Figure 3 As shown, the cross-section of the cyclone chamber 14 is circular or elliptical in the axial direction perpendicular to the dust cup 10.

[0125] The circular or elliptical cross-section 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 14, thereby improving air-dust separation efficiency. The circular or elliptical cross-section also reduces the generation of eddies and turbulence, reducing energy loss and thus maintaining airflow stability and efficient operation of the cleaning equipment 100.

[0126] In one possible implementation method, refer to Figure 2 As shown, the dust collection device 1 also includes a dust baffle 70, which is movably disposed at the air inlet 11 and is configured to open and close the air inlet 11.

[0127] The dust baffle 70 is configured to switch between a closed state (closing the air inlet 11) and an open state (opening the air inlet 11) under the influence of airflow. The dust baffle 70 has both open and closed states, effectively controlling airflow and preventing dust leakage.

[0128] When a sufficiently strong airflow enters the air inlet 11, the dust baffle 70 deforms and opens under the thrust of the airflow on the dust baffle 70, opening the air inlet 11. When the airflow stops entering the air inlet 11, the thrust of the airflow on the dust baffle 70 disappears, and the dust baffle 70 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.

[0129] By closing the air inlet 11 with the dust baffle 70, the dust baffle 70 prevents dust and debris in the cyclone chamber 14 from falling out of the air inlet 11, which helps to avoid secondary pollution when the cleaning equipment 100 is turned off or moved. It can also protect the internal components of the cleaning equipment 100 from the intrusion of dust and debris from the external environment and extend the service life of the cleaning equipment 100.

[0130] In one possible implementation, the dust baffle 70 is a thin-walled structure. The first end of the dust baffle 70 is connected to the inner wall of one side of the air inlet 11, and the second end of the dust baffle 70 is movably abutted against the inner wall of the other side of the air inlet 11. When the airflow pushes the dust baffle 70, a gap appears between the second end of the dust baffle 70 and the inner wall of the other side of the air inlet 11, thereby enabling air intake.

[0131] refer to Figure 2 As shown by the arrow, air enters the cyclone chamber 14 from the air inlet 11. The airflow forms a high-speed rotating airflow. This rotational motion causes dust and other debris to generate centrifugal force. Under the action of centrifugal force, heavier dust and debris are thrown towards the inner wall of the cyclone chamber 14. In addition, due to the gravity of the dust and other debris themselves, the dust and other debris will gradually fall into the dust collection chamber 13. This method effectively separates most of the debris from the airflow, which greatly reduces the amount of dust and debris in the air entering the filter cartridge 31. This helps to reduce the problem of hair getting tangled on the outer wall of the filter cartridge 31 and the filter cartridge 31 becoming clogged.

[0132] In one possible implementation method, refer to Figure 1 As shown, the dust collection device 1 also includes a sealing element 33, which is disposed between the outer wall of the connecting part 32 and the inner wall of the dust cup 10.

[0133] In one possible implementation, the seal 33 can be a rubber ring or a silicone ring, etc. The seal 33 can prevent air leakage and block dust in the ash storage chamber 13.

[0134] refer to Figure 8This application embodiment also provides a cleaning system 1000, which includes the cleaning device 100 and the cleaning base station 200 described above. The cleaning base station 200 is adapted to be connected to the dust outlet 16 of the dust collection device 1 of the cleaning device 100 to clean the dust collection device 1.

[0135] When using the cleaning base station 200 to clean and remove dust from the dust collection device 1, the cover plate 60 can be opened manually first. When the cover plate 60 is opened, the flexible sealing component will open both the ash outlet 16 and the ash discharge port. In this way, the cleaning base station 200 can clean the ash storage chamber 13 and the cyclone chamber 14 at the same time. It can remove the dust and impurities collected in the ash storage chamber 13, and remove the hair that adheres to the inner wall of the cyclone chamber 14, the hair that is wrapped around the outer wall of the filter assembly 30, and the foreign objects that block the filter holes 312.

[0136] Thus, the cleaning system 1000 of this embodiment can use the cleaning base station 200 to clean the dust collection chamber 13 and cyclone chamber 14 of the dust collection device 1. It can not only remove the dust and impurities collected in the dust collection chamber 13, but also remove the hair and foreign objects that adhere to the inner wall of the cyclone chamber 14, wrap around the outer wall of the filter assembly 30, and block the filter holes 312, thus ensuring the suction power of the cleaning device 100 and ensuring the cleaning effect of the cleaning device 100.
