Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to an integrated device and cleaning equipment. 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 and a cleaning equipment that can easily remove hair and foreign objects from the cyclone chamber, avoid clogging of the filter holes, and ensure the suction power of the cleaning equipment.

[0005] In a first aspect, this application provides a dust collection device, comprising: a dust cup having an air inlet, an air outlet, and a dust outlet, wherein the dust outlet is provided with an openable and closable cover; a dust-gas separator disposed within the inner cavity of the dust cup, the dust-gas separator dividing the inner cavity of the dust cup into a dust storage chamber and a cyclone chamber, the dust-gas separator having a dust-throwing port for connecting the dust storage chamber and the cyclone chamber, the cyclone chamber being connected to the air inlet, and a transfer duct for connecting the cyclone chamber and the air outlet further defining a connection between the dust cup and the dust-gas separator, wherein at least a portion of the structure of the transfer duct is located on the side of the dust-gas separator facing away from the dust storage chamber; and a filter assembly comprising a filter cylinder located within the cyclone chamber and upstream of the transfer duct along the airflow path, the filter assembly being used to separate dust and gas in the airflow entering the cyclone chamber.

[0006] The dust collection device of this application, during the operation of the cleaning equipment, allows dust, hair, and other debris sucked in by the floor brush device to enter the cyclone chamber through the air inlet. Under the action of centrifugal force, the debris spirals along the inner wall of the cyclone chamber, reducing the accumulation of debris on the surface of the filter cartridge and mitigating filter pore clogging. As the airflow moves from the air inlet to the air outlet, the centrifugal force propels the dust and debris to the ash-throwing port, where they are thrown into the ash-storage chamber. During cleaning, the dust in the ash-storage chamber can be emptied through the ash-storage port, ensuring smooth airflow within the device and maintaining stable suction, thus guaranteeing cleaning efficiency and effectiveness and reducing the frequency of filter cartridge cleaning. Furthermore, by placing at least a portion of the transfer duct on the side of the dust-air separator facing away from the ash-storage chamber, the transfer duct avoids occupying internal space in the ash-storage chamber, allowing for the storage of more dust and impurities.

[0007] In some embodiments, the dust-air separator includes a side partition and a bottom partition, the side partition being connected between the inner walls of opposite sides of the dust cup, the bottom partition being connected to the side partition, and the bottom partition shielding the end of the cyclone chamber away from the air outlet; a portion of the structure of each of the side partition and the bottom partition extends toward the air inlet to form a connecting channel communicating with the air inlet, and at least a portion of the structure of the transfer duct is located between the side partition and the dust cup.

[0008] 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 the airflow to rotate within the cyclone chambers. The bottom baffle seals the end of the cyclone chamber furthest from the outlet, ensuring an effective rotational path for the airflow within the cyclone chamber, thus increasing the separation efficiency of dust and other debris from the air. The combination of the bottom and side baffles ensures that airflow and impurities exit from the ash-throwing port into the ash storage chamber.

[0009] According to some embodiments of this application, the filter cylinder is surrounded by a filter cavity, and the side wall of the filter cylinder is provided with a plurality of filter holes that connect the cyclone cavity and the filter cavity. The filter cavity is connected to the air outlet through the transfer duct.

[0010] 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 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.

[0011] According to some embodiments of this application, a suction port is provided on the bottom partition, the filter cylinder is covered at the suction port, and the connecting air duct includes: a first air duct section and a second air duct section. The first air duct section extends radially along the dust-gas separator and is located on the side of the bottom partition away from the air outlet. The second air duct section extends axially along the dust-gas separator and is connected to the first air duct section and the air outlet respectively.

[0012] This design allows the airflow entering the cyclone chamber through the inlet, filtering through the filter cartridge, and then, under the negative pressure suction at the suction port, exiting through the transfer duct and out of the outlet. The suction port is located below the inlet, facilitating full utilization of the dust cup's internal space and allowing for the design of the transfer duct. Complete airflow circulation can be achieved without increasing the dust cup volume, resulting in a more compact dust collection device that can accommodate cleaning equipment of different sizes. Furthermore, the first and second duct sections define a horizontal-vertical transfer duct within the dust cup, preventing sharp turns or narrow passages caused by forced adaptation to space. This ensures a smoother flow velocity change as the airflow travels from the suction port through the first and second duct sections to the outlet, effectively reducing airflow resistance loss during the turning process and ensuring efficient transfer of negative pressure to the suction port, thus guaranteeing the dust collection device's suction efficiency. At the same time, it also improves the space utilization rate inside the dust cup. Without affecting the core functions such as dust-gas separation and filtration, the transfer air duct is arranged, which is conducive to improving the overall compactness of the dust collection device.

[0013] According to some embodiments of this application, the cross-section of the filter cartridge gradually decreases along the axial direction of the dust-gas separator and from the suction port to the air outlet.

[0014] In this way, the filter cartridge forms a tapered structure similar to a cone. The cross-section of the end of the filter cartridge facing away from the suction port is smaller, which is conducive to accurately capturing the airflow in the core area of ​​the cyclone chamber. The filtration range is expanded at the end of the filter cartridge facing the suction port, which helps to shorten the flow path of the airflow in the filter cartridge. Combined with the negative pressure of the suction port and the airflow diversion of the transfer duct, the airflow resistance loss is effectively reduced, the airflow dynamics are enhanced, and the filtered airflow is output to the air outlet more efficiently, ensuring the overall suction performance of the dust collection device is stable.

[0015] According to some embodiments of this application, the ash-throwing port is opened at one end of the side partition adjacent to the air outlet, and the end of the filter cartridge facing the air outlet is not lower than the edge of the ash-throwing port away from the air outlet.

[0016] According to some embodiments of this application, the filter assembly further includes: a mounting bracket disposed on the side of the dust-air separator facing the air outlet and connected to the inner wall of the dust cup; the mounting bracket defines an air passage cavity that connects the transfer duct and the air outlet.

[0017] By setting up the mounting bracket, on the one hand, the mounting bracket forms a horizontal support structure inside the dust cup, which can not only fix the dust-gas separator axially and prevent the dust-gas separator from shifting axially under equipment vibration or airflow impact, but also enhance the structural strength of the inner wall of the dust cup and prevent the dust cup from deforming due to external collision or internal negative pressure.

[0018] According to some embodiments of this application, the filtering assembly further includes at least one first filter element disposed within the air passage cavity.

[0019] 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.

[0020] According to some embodiments of this application, 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.

[0021] 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.

[0022] Secondly, this application provides a cleaning device, including a main body and the aforementioned dust collection device.

[0023] 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.

[0046] 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.

[0047] 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.

[0048] In view of this, this application provides a dust collection device and a cleaning device. 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 device to maintain stable suction, ensures cleaning efficiency and effectiveness, and reduces the frequency of cleaning the filter cartridge by the user.

[0049] 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.

[0050] 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 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.

[0051] 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.

[0052] refer to Figures 1 to 5 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.

[0053] 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 of the dust cup 10 through the air outlet 12. The air inlet 11 can be located above or below the air outlet 12.

[0054] The ash outlet 16 can be opened after the cleaning equipment 100 has finished cleaning, so as to clean out the dust and debris collected in the dust cup 10. For example, the user can manually open the ash outlet 16 and pour out the dust and debris, or the cleaning base station can suck out the dust and debris from the ash outlet 16. Understandably, the ash outlet 16 can be provided with a cover plate 60 for opening and closing 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 of course, other connection methods can be used.

[0055] The dust-gas separator 20 is disposed in the inner cavity of the dust cup 10. The dust-gas separator 20 can divide the interior 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.

[0056] 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 the dust-air separator 20 has a dust-throwing port 21 that 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. Along the axial direction of the dust cup 10, the dust-throwing port 21 is located on the side of the air inlet 11 facing the air outlet 12. 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.

[0057] A transition duct 40 is defined between the dust cup 10 and the dust-gas separator 20 for connecting the cyclone chamber 14 and the air outlet 12. At least a portion of the structure of the transition duct 40 is located on the side of the dust-gas separator 20 facing away from the ash storage chamber 13. By placing at least a portion of the structure of the transition duct 40 on the side of the dust-gas separator 20 facing away from the ash storage chamber 13, the transition duct 40 can avoid occupying the internal space of the ash storage chamber 13, thereby accommodating more dust and impurities.

[0058] A filter assembly 30 is disposed within the dust cup 10. The filter assembly 30 includes a filter cartridge 31, which is located within the cyclone chamber 14 and upstream of the transfer duct 40 along the airflow path. The filter assembly 30 is used to separate dust and air in the airflow entering the cyclone chamber 14. 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 through the transfer duct 40 after passing through the filter assembly 30.

[0059] When the dust collection device 1 performs self-cleaning, the cover plate 60 is opened, thereby opening the ash outlet 16. This allows the dust in the ash storage chamber 13 to be emptied through the ash outlet 16, keeping the dust collection device 1 clean and ensuring smooth airflow inside, thus guaranteeing the suction power and cleaning effect of the cleaning equipment 100. Here, self-cleaning refers to cleaning the dust collection device 1, such as removing the dust and impurities collected inside.

[0060] 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 cavity 14 from the air inlet 11 with the airflow. They are 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 14, reducing the accumulation of debris on the surface of the filter cartridge 31 in the cyclone cavity 14 and reducing the problem of clogging of the filter holes 312 of the filter cartridge 31. During the process of the airflow from the air inlet 11 to the air outlet 12, under the action of the centrifugal force of the cyclone, the dust and debris move to the position of the ash throwing port 21 and are thrown into the ash storage cavity 13.

[0061] When cleaning the dust collection device 1, the dust in the dust storage chamber 13 can be emptied through the dust outlet 16, thereby ensuring smooth airflow inside the dust collection device 1, enabling the cleaning equipment 100 to maintain stable suction, ensuring cleaning efficiency and effectiveness, and reducing the frequency of cleaning the filter cartridge 31 by the user.

[0062] Furthermore, since at least a portion of the structure of the transfer duct 40 is located on the side of the dust-air separator 20 facing away from the ash storage chamber 13, the transfer duct 40 can avoid occupying the internal space of the ash storage chamber 13, thereby accommodating more dust and impurities.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] In some possible embodiments, the ash outlet 16 can be used to connect to a cleaning base station, that is, the dust collection device 1 can be self-cleaned through the cleaning base station.

[0068] The dust collection device 1 is configured such that when the cleaning base station is connected to the dust outlet 16, the cover 60 is opened by the airflow driven by at least one of the cleaning base station and the cleaning equipment 100.

[0069] For example, a dust removal motor can be installed on the cleaning base station. When the dust removal motor is running, it generates negative pressure in the internal air duct of the cleaning base station. When the dust outlet 16 of the dust collection device 1 is connected to the cleaning base station, the negative pressure generated by the dust removal motor drives the cover plate 60 to open, thereby opening the dust outlet 16 and sucking the dust in the dust collection device 1 into the cleaning base station.

[0070] 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, the suction motor of the cleaning device 100 reverses in the second rotation direction to generate a pushing force on the cover plate 60, thereby opening the dust outlet 16 and blowing the dust in the dust collection device 1 into the cleaning base station. The first rotation direction and the second rotation direction are opposite.

[0071] 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, the air duct of the cleaning equipment 100 is connected to the internal air duct of the cleaning base station through the air duct switching device. The suction force generated by the suction motor of the cleaning equipment 100 acts on the cover plate 60 from the side of the cleaning base station, thereby opening the dust outlet 16 and sucking the dust in the dust collection device 1 into the cleaning base station.

[0072] In this way, by cleaning the dust collection device 1 through the base station cleaning, the user can be spared the need to manually clean the dust collection device 1, which can improve cleaning efficiency and effectiveness.

[0073] Of course, in addition to the above-mentioned method of opening and closing the cover 60 by the suction force of the cleaning device 100 and the cleaning base station, the cover 60 can also be set to open manually. For example, the cover 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, helping to ensure that air smoothly leaves the dust collection device 1 through the air outlet 12, reducing air resistance and improving overall efficiency. The cover 60 can be opened to empty the accumulated dust in the ash storage chamber 13, facilitating maintenance and cleaning. With this design, users can easily open the ash storage chamber 13, empty the collected dust and particles, and keep the cleaning device 100 clean and operating efficiently.

[0074] One side of the cover plate 60 is hinged to the dust cup 10, and the other side of the cover plate 60 is mechanically locked to the dust cup 10.

[0075] refer to Figure 1 and Figure 5 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. The cover plate 60 has a hook part. 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.

[0076] The user operates the control button 15 to lock and release the cover 60. The locking part 152 extends into the hook part 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, the cover 60 is released, allowing it to be opened and enabling the cleaning of dust and debris from the ash storage chamber 13.

[0077] In one possible implementation, the locking part 152 has a latching protrusion, and the stop hook is typically a recessed structure designed to accommodate the size and shape of the latching protrusion, ensuring that the latching protrusion can be smoothly inserted into the stop hook and remain stable. When the latching protrusion extends into the stop hook, the inner wall of the stop hook 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.

[0078] In one possible implementation method, refer to Figure 5 The operation button 15 also 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. The rotating part 153 is disposed at the connection position of the pressing part 151 and the locking part 152. The operation button 15 is rotatably disposed on the dust cup 10 through the rotating part 153.

[0079] 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 and unlocking the cover plate 60.

[0080] In one possible implementation method, refer to Figure 5 The pivot 153 is also provided with a torsion spring, which is used to reset the operation button 15 when the pressing part 151 is released, so as to ensure that the locking part 152 can stably cooperate with the hook part to achieve the locking effect of the cover plate 60.

[0081] In one possible implementation, a sealing ring 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.

[0082] In some embodiments, the dust ejection port 21 is located on the side of the air inlet 11 facing the air outlet 12. This provides a longer flow path for the airflow, which is beneficial for improving the dust-air separation effect.

[0083] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4The 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 the bottom partition 23 blocks the end of the cyclone chamber 14 away from the air outlet 12. The ash-throwing port 21 is opened at the end of the side partition 22 adjacent to the air outlet 12. For example, the ash-throwing port 21 can be opened at the end of the side partition 22 away from the bottom partition 23. The top of the side partition 22 forms a notch structure, which constitutes the ash-throwing port 21. The structure is simple. The ash-throwing port 21 is located above the air inlet 11 so that the dust and other debris separated in the cyclone chamber 14 can be discharged from the ash-throwing port 21 under the action of the centrifugal force of the cyclone, ensuring the smooth flow of dust and other debris from the ash-throwing port 21 into the ash storage chamber 13.

[0084] Parts of the side partition 22 and the bottom partition 23 extend toward the air inlet 11 to form a connecting channel 24 communicating with the air inlet 11. Exemplarily, a portion of the bottom partition 23 extends toward the air inlet 11 to form the bottom wall of the connecting channel 24, and a portion of the side partition 22 protrudes toward the air inlet 11 to form the peripheral wall of the connecting channel 24. At least a portion of the structure of the transfer duct 40 is located between the side partition 22 and the dust cup 10.

[0085] 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.

[0086] 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.

[0087] In one possible implementation, the side partition 22 is arc-shaped, making the cyclone cavity 14 nearly cylindrical.

[0088] In one possible implementation, the extension direction of the connecting channel 24 can be tangent to the side partition 22 so that the airflow entering the cyclone chamber 14 from the air inlet 11 has an initial angular velocity, thereby improving the dust-air separation effect.

[0089] In one possible implementation, the bottom partition 23 is in the form of a horizontal panel.

[0090] In one possible implementation, the filter cylinder 31 is surrounded by a filter cavity 311, which is connected to the air outlet 12 via a transition air duct 40. 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.

[0091] The filter cartridge 31 is used for preliminary filtration to block dust and debris from entering the cyclone chamber 14, effectively removing larger particles. Air filtered by the filter cartridge 31 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 discharged into the dust storage chamber 13 through the dust 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 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.

[0092] 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.

[0093] In one possible implementation method, refer to Figure 2 and Figure 4 A suction port 231 is provided on the bottom partition plate 23, and a filter cylinder 31 is covered on the suction port 231. A transfer air duct 40 is also provided between the dust cup 10 and the dust-air separation component 20. The transfer air duct 40 is used to connect the suction port 231 and the air outlet 12.

[0094] In this way, the airflow entering the cyclone chamber 14 enters the cyclone chamber 14 through the air inlet 11, is filtered by the filter cartridge 31, and then, under the negative pressure suction at the suction port 231, the airflow is discharged from the suction port 231 through the transfer duct 40 and out of the air outlet 12. The suction port 231 is located below the air inlet 11, which makes it easy to make full use of the internal space of the dust cup 10 and facilitates the setting of the transfer duct 40. It can achieve complete airflow circulation without increasing the volume of the dust cup 10, making the dust collection device 1 more compact and adaptable to cleaning equipment 100 of different sizes.

[0095] In one possible implementation, the filter cartridge 31 can be installed on the suction port 231 by bonding, welding or snap-fitting, or the filter cartridge 31 can be integrally formed with the dust-gas separator 20.

[0096] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4 Along the axial direction of the dust-gas separator 20 and from the suction port 231 to the air outlet 12, the cross-section of the filter cartridge 31 gradually decreases.

[0097] Thus, the filter cartridge 31 forms a tapered structure. The cross-section of the end of the filter cartridge 31 facing away from the suction port 231 is smaller, which is conducive to accurately capturing the airflow in the core area of ​​the cyclone chamber 14. The filtration range is expanded by the end of the filter cartridge 31 facing the suction port 231, which helps to shorten the flow path of the airflow in the filter cartridge 31. Combined with the negative pressure of the suction port 231 and the airflow diversion of the transfer duct 40, the airflow resistance loss is effectively reduced, the airflow flow power is enhanced, and the filtered airflow is output to the air outlet 12 more efficiently, ensuring the overall suction performance of the dust collection device 1 is stable.

[0098] In one possible implementation, the longitudinal section of the filter cartridge 31 is inverted "U" shape.

[0099] The top 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.

[0100] In one possible implementation, the end of the filter cartridge 31 facing the air outlet 12 is not lower than the edge of the dust-throwing port 21 away from the air outlet 12. For example, the top of the filter cartridge 31 is not lower than the bottom edge of the dust-throwing port 21. This ensures that the spiral airflow flows spirally around the surface of the filter cartridge 31 to the height corresponding to the dust-throwing port 21, thereby ensuring that dust and impurities can be thrown into the dust storage chamber 13.

[0101] In one possible implementation method, refer to Figure 2 , Figure 3 and Figure 4 The transition duct 40 may include a first duct section 41 and a second duct section 42. The first duct section 41 extends radially along the dust-gas separator 20 and is located on the side of the bottom partition 23 facing away from the air outlet 12. The second duct section 42 is located between the side partition 22 and the dust cup 10. The second duct section 42 extends axially along the dust-gas separator 20 and connects the first duct section 41 and the air outlet 12.

[0102] By defining a horizontal-vertical transition duct 40 within the dust cup 10 through the first air duct section 41 and the second air duct section 42, the sharp turns or narrow channels caused by the forced adaptation of the air duct to the space are avoided. This allows the airflow velocity to change more gradually as it flows from the suction port 231 through the first air duct section 41 and the second air duct section 42 to the air outlet 12, effectively reducing airflow resistance loss during the turning process. This ensures that the negative pressure can be efficiently transmitted to the suction port 231, guaranteeing the suction efficiency of the dust collection device 1. At the same time, it also improves the space utilization rate inside the dust cup 10. Arranging the transition duct 40 without affecting the core functions such as dust-air separation and filtration is beneficial to improving the overall compactness of the dust collection device 1.

[0103] In one possible implementation, the connection between the first air duct section 41 and the second air duct section 42 is rounded. On the one hand, this reduces the airflow resistance loss during the turning process, ensuring that the negative pressure can be efficiently transmitted to the suction port 231 and guaranteeing the suction efficiency of the dust collection device 1. On the other hand, it prevents dust from accumulating at the connection between the first air duct section 41 and the second air duct section 42, which would cause blockage of the transfer air duct 40 and improve the structural reliability of the dust collection device 1.

[0104] In one possible implementation, the filter assembly 30 further includes a mounting bracket 32 ​​disposed on the side of the dust-air separator 20 facing the air outlet 12. Exemplarily, the mounting bracket 32 ​​is disposed on the top of the dust-air separator 20 and connected to the inner wall of the dust cup 10. The mounting bracket 32 ​​defines an air passage cavity 321 that connects the transfer duct 40 and the air outlet 12.

[0105] By setting the mounting bracket 32, on the one hand, the mounting bracket 32 ​​forms a transverse support structure inside the dust cup 10, which can not only fix the dust-gas separator 20 axially and prevent the dust-gas separator 20 from shifting axially under equipment vibration or airflow impact, but also enhance the structural strength of the inner wall of the dust cup 10 and prevent the dust cup 10 from deforming due to external collision or internal negative pressure.

[0106] In one possible implementation, the mounting bracket 32 ​​and the inner wall of the dust cup 10 can be connected by a snap-fit ​​or an interference fit.

[0107] In one possible implementation, the mounting bracket 32 ​​may be basin-shaped, and the mounting bracket 32 ​​and the dust and gas separator 20 may be an integral structure connected as one piece, or they may be separate structures.

[0108] In one possible implementation, the filter assembly 30 further includes at least one first filter element 50 disposed within the air passage cavity 321. The first filter element 50 can perform secondary filtration on the airflow that has been initially filtered by the filter cartridge 31, thereby reducing the risk of impurities being drawn into the suction motor.

[0109] In one possible implementation, the number of first filter elements 50 can be two or more to improve the filtration effect. The multiple first filter elements 50 can be made of the same material or different materials.

[0110] In one possible implementation, the filter assembly 30 includes two first filter elements 50, 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.

[0111] In one possible implementation, refer to 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.

[0112] 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.

[0113] In one possible implementation method, refer to Figure 3 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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. 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 problem of the filter cartridge 31 being blocked.

[0119] In one possible implementation method, refer to Figure 2 As shown, the dust collection device 1 also includes a sealing element 33, which is disposed between the outer wall of the mounting bracket 32 ​​and the inner wall of the dust cup 10.

[0120] 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.

[0121] refer to Figure 6 and Figure 7 Secondly, this application provides a cleaning device 100, including a device body 2 and the aforementioned dust collection device 1.

[0122] The cleaning device 100 of this application, by setting the dust collection device 1 mentioned above, can not only remove the dust and impurities collected in the dust storage chamber 13 of the dust collection device 1, 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, thereby ensuring the suction power and cleaning effect of the cleaning device 100.
