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 have issues with handling long hair and large particles. Because the separation of hair and other impurities within the cyclone chamber is not very effective, they tend to get stuck inside the cyclone chamber and eventually become entangled on the outer wall of the filter cartridge, causing the filter holes to become clogged. This requires manual cleaning by the user. Furthermore, 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 reduce the risk of hair and foreign objects clogging the cyclone chamber 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 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 spaced apart from and connected to the air inlet; and a filter assembly disposed within the dust cup, the filter assembly including a filter cylinder extending into the cyclone chamber to separate dust and gas in the airflow entering the cyclone chamber.

[0006] The dust collection device of this application embodiment, due to the spaced arrangement of the cyclone chamber and the air inlet, allows the airflow to enter the cyclone chamber from the air inlet during cleaning operation. This creates a concentrated and directional airflow within the flow space between the cyclone chamber and the air inlet, making it easier for the airflow to form a strong spiral airflow around the filter assembly. Dust, hair, and other debris carried in the airflow are subjected to both the centrifugal force of the cyclone and their own gravity. 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 blockage. The dust and other debris, under 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 more easily thrown into the ash-storage chamber, preventing incomplete separation from the cyclone chamber and subsequent blockage. When cleaning the dust collection device, the dust in the dust storage chamber can be emptied through the dust outlet, which will allow the airflow inside the dust collection device to be smooth, enabling the cleaning equipment to maintain stable suction, ensuring cleaning efficiency and effectiveness, and reducing the frequency of users cleaning the filter cartridge.

[0007] In some embodiments, the air inlet is located on the side wall of the dust cup, and the cyclone chamber and the air inlet are arranged opposite to each other and spaced apart along the opening direction of the air inlet.

[0008] 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 bottom of the side partition and perpendicular to the height direction of the dust cup. The ash-throwing port is opened on at least one of the side partition and the bottom partition. The side partition has a notch communicating with the cyclone chamber and the notch communicating with the air inlet.

[0009] 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.

[0010] In some embodiments, the side partition includes: a partition body that surrounds the cyclone cavity, and the notch is provided in the partition body; a pipe section, one end of which is connected to the periphery of the notch, and the other end of which is connected to the periphery of the air inlet, the inner side of which defines a connecting channel connecting the air inlet and the cyclone cavity, and one inner wall of the connecting channel being tangent to the inner wall of the cyclone cavity.

[0011] Thus, when the cleaning equipment is performing cleaning operations, the airflow enters the cyclone chamber from the air inlet through the connecting channel. Since the connecting channel has a certain degree of extension and the inner wall of the connecting channel is tangent to the inner wall of the cyclone chamber, the airflow is more likely to form a spiral airflow after entering the cyclone chamber under the guidance of the connecting channel, which helps to improve the dust and gas separation effect.

[0012] In some embodiments, the duct portion is located on the side of the ash-throwing port away from the bottom partition along the axial direction of the cyclone chamber; and / or, the duct portion is spaced apart from the inner wall of the dust cup on both sides along the circumferential direction of the cyclone chamber.

[0013] The duct section is located on the side of the cyclone chamber away from the bottom partition along the axial direction of the dust ejection port. This ensures that the airflow enters the cyclone chamber from the air inlet and spirals for at least one revolution, forming a spiral airflow that effectively carries hair, particles, and other impurities out of the dust ejection port. The duct section is spaced apart from the inner wall of the dust cup on both sides along its width, allowing the air separated from the impurities to flow from both sides of the duct section to the air outlet. This improves the airflow efficiency inside the dust collection device and enhances the cleaning effect of the cleaning equipment.

[0014] In some embodiments, at least a portion of the structure on the baffle body located on both sides of the ash discharge port along the circumference of the cyclone chamber is spaced apart from the inner wall of the dust cup, such that the ash storage chamber at least partially surrounds the dust-gas separator.

[0015] In this way, on the one hand, the volume of the ash storage chamber can be increased to accommodate more dust, hair and other impurities. On the other hand, the airflow area in the ash storage chamber is larger, which makes the airflow efficiency higher. When the cleaning equipment is performing cleaning operations, it helps to reduce the loss of airflow in the dust collection device, thereby improving the dust collection effect.

[0016] In some embodiments, the partition body includes a first side portion facing the air inlet along the opening direction of the air inlet and a second side portion facing away from the air inlet, the second side portion being connected to the side wall of the dust cup opposite to the air inlet, and the area of ​​the partition body other than the second side portion being spaced apart from the dust cup.

[0017] In this way, on the one hand, the volume of the ash storage chamber can be increased to accommodate more dust, hair and other impurities. On the other hand, the airflow area in the ash storage chamber is larger, which makes the airflow efficiency higher. When the cleaning equipment is performing cleaning operations, it helps to reduce the loss of airflow in the dust collection device, thereby improving the dust collection effect.

[0018] In some embodiments, the ash-throwing port includes a first boundary and a second boundary that are circumferentially opposite each other along the cyclone cavity, wherein, along the opening direction of the air inlet, the distance between the first boundary and the air inlet is less than the distance between the second boundary and the air inlet, wherein the first boundary is arranged opposite to the air inlet.

[0019] By adjusting the position of the ash-throwing port on the dust-air separation component along the circumference of the cyclone chamber, the distance between the ash-throwing port and the inner wall of the dust cup on the side of the air inlet can be adjusted, making it easier for dust, hair and other debris to enter the ash storage chamber from the ash-throwing port, and making the internal air passage of the dust collection device smoother.

[0020] In some embodiments, the air outlet is located at the top of the dust cup, the ash outlet is located at the bottom of the dust cup, and the bottom partition and the cover plate are arranged at intervals along the height direction of the dust cup.

[0021] This allows for sufficient space between the bottom partition and the cover plate to accommodate dust and impurities, preventing impurities in the ash storage chamber from flowing back into the cyclone chamber through the ash throwing port.

[0022] In some embodiments, the filter cylinder has an interior forming a filter cavity, and the side wall of the filter cylinder has a plurality of filter holes that connect the cyclone cavity and the filter cavity.

[0023] 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.

[0024] In some embodiments, the top end 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 top end of the dust-air separator abuts against the connecting portion.

[0025] In this way, the connecting part can be used to fix the filter cartridge to the inner wall of the dust cup, ensuring the stability of the filter cartridge inside the dust cup. In addition, the dust-air separation component plays a supporting role for the connecting part, improving the stability of the filter cartridge.

[0026] In some embodiments, the filtering assembly further includes at least one first filter element disposed within the air passage cavity.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Secondly, this application provides a cleaning device, including a main body and the aforementioned dust collection device.

[0031] 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.

[0032] 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.

[0033] 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.

[0059] 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.

[0060] 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 separates dust and air and collects dust and debris. However, some vacuum cleaner models have problems when dealing with long hair and large particles. Because hair and other impurities are not effectively separated in the cyclone chamber, they tend to get stuck inside and eventually become entangled on the outer wall of the filter cartridge, causing filter pores to become clogged. This requires manual cleaning by the user. Furthermore, clogged filter pores can reduce the vacuum cleaner's suction power, making it difficult to suck up hair, dust, and mites, thus affecting cleaning effectiveness.

[0061] In view of this, this application provides a dust collection device, a cleaning equipment, and a cleaning system. Dust, hair, and other debris carried in the airflow are subjected to the combined effects of cyclone centrifugal force and their own gravity. The cyclone centrifugal force causes the debris to spiral along the inner wall of the cyclone cavity, reducing the accumulation of debris on the surface of the filter cartridge within the cyclone cavity and reducing the problem of filter pore blockage. Dust and other debris, under the influence of their own gravity, will descend within the cyclone cavity. When the dust and debris move to the ash-throwing port under the combined action of gravity and centrifugal force, the debris is more easily thrown from the ash-throwing port into the ash-storage cavity, avoiding incomplete separation from the cyclone cavity and causing blockage. This ensures smooth airflow inside the dust collection device, allowing the cleaning equipment to maintain stable suction, ensuring cleaning efficiency and effectiveness, and reducing the frequency of filter cartridge cleaning for users.

[0062] refer to Figures 6-8 The cleaning device 100 in this application embodiment includes, but is not limited to, a vacuum cleaner. The cleaning device 100 may include the device body 2 and the dust collection device 1 described above.

[0063] The main body 2 of the device may include a floor brush device and a main unit. The main unit may include 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.

[0064] 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.

[0065] refer to Figures 1-5 The dust collection device 1 in this embodiment may include: a dust cup 10, a dust-gas separator 20, and a filter assembly 30.

[0066] The dust cup 10 has a hollow cavity inside, and its cross-section perpendicular to the axis can be circular, elliptical, oblong, 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, so that the floor brush device can discharge impurities from the ground into the dust cup 10. The air outlet 12 can be connected to the drive component 202 of the cleaning equipment 100, such as a suction motor, so that the suction motor applies negative pressure to the inner cavity of the dust cup 10 through the air outlet 12.

[0067] 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 200 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.

[0068] The dust-gas separator 20 is disposed inside 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 storage chamber 13 is located on the outside of the dust-gas separator 20, and the dust throwing chamber is located on the inside of the dust-gas separator 20. 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. The air inlet 11 and the cyclone chamber 14 are spaced apart and connected. For example, the air inlet 11 and the cyclone chamber 14 are connected by a pipe structure (such as a connecting pipe or the pipe part 222 mentioned below). 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.

[0069] 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.

[0070] The filter assembly 30 is disposed inside the dust cup 10. The filter assembly 30 includes a filter cartridge 31 extending into the cyclone chamber 14 to separate dust and gas in the airflow entering the cyclone chamber 14.

[0071] Because the cyclone chamber 14 and the air inlet 11 are spaced apart, the airflow from the air inlet 11 to the cyclone chamber 14 can form a concentrated and directional airflow (from the air inlet 11 to the cyclone chamber 14) using the flow space between them. This makes it easier for the airflow to form a strong spiral airflow around the filter assembly 30 after entering the cyclone chamber 14. This allows the dust and impurities filtered by the filter assembly 30 to be more easily thrown from the cyclone chamber 14 into the dust storage chamber 13 through the dust ejection port 21. The filtered air can then flow to the air outlet 12 after passing through the filter assembly 30. This prevents hair and other impurities from remaining in the dust ejection chamber and adhering to the outer wall of the filter cylinder 31 and the inner wall of the cyclone chamber 14.

[0072] Additionally, when the cleaning equipment 100 is cleaning, the cover plate 60 can close the ash discharge port to ensure that the airflow flows from the air inlet 11 through the cyclone chamber 14, the ash discharge port 21, and the ash storage chamber 13 to the air outlet 12. When the dust collection device 1 is self-cleaning, the cover plate 60 can be opened to open the ash discharge port 16, allowing the accumulated dust, hair, and other impurities in the ash storage chamber 13 to be emptied, 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 it.

[0073] In this embodiment of the dust collection device 1, because the cyclone chamber 14 and the air inlet 11 are spaced apart, when the cleaning device 100 is working, when the airflow enters the cyclone chamber 14 from the air inlet 11, it can utilize the flow space between the cyclone chamber 14 and the air inlet 11 to form a concentrated and directional airflow. This makes it easier for the airflow to form a strong spiral airflow around the filter assembly 30 after entering the cyclone chamber 14. The dust, hair, and other debris carried in the airflow are subjected to the combined effects of the centrifugal force of the cyclone and their own gravity. Centrifugal force causes 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 within the cyclone chamber 14 and mitigating the problem of clogging of the filter holes 312. Dust and other debris, under their own gravity, descend within the cyclone chamber 14. When the dust and debris reach the ash-throwing port 21 under the combined action of gravity and centrifugal force, they are more easily thrown into the ash-storage chamber 13, preventing incomplete separation from the cyclone chamber 14 and subsequent clogging. When cleaning the dust collection device 1, the dust in the ash-storage chamber 13 can be emptied through the ash outlet 16, ensuring smooth airflow within the dust collection device 1. This allows the cleaning equipment 100 to maintain stable suction, ensuring cleaning efficiency and effectiveness, and reducing the frequency of cleaning the filter cartridge 31.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] In some embodiments, combined with Figure 2 and Figure 3 The air inlet 11 is located on the side wall of the dust cup 10. This allows for greater flexibility in the placement of the air inlet 11 in the height direction of the dust cup 10, thus meeting the requirements for forming a spiral airflow. The cyclone chamber 14 and the air inlet 11 are arranged opposite each other and spaced apart along the opening direction of the air inlet 11. This helps to shorten the distance between the cyclone chamber 14 and the air inlet 11 to a certain extent, thereby simplifying the air path structure within the dust collection device 1 as much as possible while taking into account the airflow intensity within the cyclone chamber 14.

[0078] In one possible implementation method, combining Figures 1-3The 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. The bottom partition 23 is connected to the bottom of the side partition 22 and covers the end of the cyclone chamber 14 away from the air outlet 12. The bottom partition 23 is perpendicular to the height direction of the dust cup 10. The dust discharge port 21 is opened on at least one of the side partition 22 and the bottom partition 23. The side partition 22 has a notch 2210 communicating with the cyclone chamber 14. The notch 2210 communicates with the air inlet 11, that is, the cyclone chamber 14 is connected to the air inlet 11 through the notch 2210.

[0079] The side baffle 22, through its own barrier function, divides the hollow cavity inside the dust cup 10 into adjacent ash storage chamber 13 and cyclone chamber 14. The side baffle 22 can guide the airflow to form a rotational motion within the cyclone chamber 14. The bottom baffle 23 closes the end of the cyclone chamber 14 away from the air outlet 12, ensuring that the airflow forms an effective rotational path within the cyclone chamber 14, which helps to increase the separation efficiency of dust and other debris from the air. Through the cooperation of the bottom baffle 23 and the side baffle 22, it is ensured that the airflow and impurities are discharged from the ash throwing port 21 into the ash throwing chamber and enter the ash storage chamber 13.

[0080] Optionally, the ash discharge port 21 may be provided only on the side partition 22; or, the ash discharge port 21 may be provided only on the bottom partition 23; or, part of the ash discharge port 21 may be provided on the side partition 22 and the other part on the bottom partition 23. Thus, the arrangement of the ash discharge port 21 is diverse and can be selected according to needs.

[0081] Further, refer to Figure 1 and Figure 2 The ash discharge port 21 can be set only at the end of the side partition 22 that is connected to the bottom partition 23. This structure makes the bottom of the side of the ash discharge port 21 flush with the bottom partition 23, which is conducive to the smooth discharge of dust and other debris separated in the cyclone chamber 14 through the ash discharge port 21, and ensures the smooth flow of dust and other debris from the ash discharge port 21 into the ash storage chamber 13.

[0082] In one possible implementation method, refer to Figure 2 The side partition 22 is circular, making the cyclone cavity 14 cylindrical. This helps to reduce the wind resistance inside the cyclone cavity 14, making it easier for impurities such as hair to be discharged from the cyclone cavity 14 with the airflow.

[0083] In some embodiments, combined with Figure 2 and Figure 3The central axis of the cyclone chamber 14 is offset from the central axis of the dust cup 10, meaning the cyclone chamber 14 and the dust cup 10 are eccentrically positioned. On one hand, this eccentric design allows the airflow to create a stronger rotational effect upon entering the cyclone chamber 14, thereby enhancing centrifugal force. This helps to more effectively separate dust particles from the airflow, improving overall separation efficiency. On the other hand, it also optimizes the airflow path inside the dust cup 10 to some extent, reducing airflow turbulence and vibration, which helps to reduce the noise generated during the operation of the cleaning device 100 and improve the user experience. Furthermore, this design allows for better utilization of the space inside the dust cup 10, enabling the dust collection device 1 to hold more dust and particles without increasing its overall volume.

[0084] In some embodiments, combined with Figure 2 and Figure 3 The side partition 22 may include a partition body 221 and a duct section 222. The partition body 221 is generally cylindrical with open ends, and it can enclose a cyclone cavity 14 with a circular cross-section. A notch 2210 can be formed on the partition body 221. One end of the duct section 222 is connected to the periphery of the notch 2210, and the other end is connected to the periphery of the air inlet 11. The inner side of the duct section 222 defines a connecting channel 223 that connects the air inlet 11 and the cyclone cavity 14. One inner wall of the connecting channel 223 is tangent to the inner wall of the cyclone cavity 14.

[0085] Thus, when the cleaning equipment 100 is performing cleaning operations, the airflow enters the cyclone chamber 14 from the air inlet 11 through the connecting channel 223. Since the connecting channel 223 has a certain degree of extension and the inner wall of the connecting channel 223 is tangent to the inner wall of the cyclone chamber 14, the airflow is more likely to form a spiral airflow after entering the cyclone chamber 14 under the guidance of the connecting channel 223, which helps to improve the dust and gas separation effect.

[0086] In some embodiments, reference Figure 3 The duct section 222 is located on the side of the ash-throwing port 21 away from the bottom partition plate 23 along the axial direction of the cyclone chamber 14. In other words, the duct section 222 and the ash-throwing port 21 are distributed on the partition plate body 221 along the axial direction of the cyclone chamber 14. This ensures that the airflow enters the cyclone chamber 14 from the air inlet 11 and flows in a spiral at least once to form a spiral airflow, so as to carry away impurities such as hair and particles out of the ash-throwing port 21.

[0087] Optionally, refer to Figure 3 The duct section 222 is spaced apart from the inner wall of the dust cup 10 on both sides of the circumference of the cyclone chamber 14. In this way, the air separated from the impurities can flow from both sides of the duct section 222 to the air outlet 12, which is conducive to improving the airflow efficiency inside the dust collection device 1 and helps to improve the cleaning effect of the cleaning equipment 100.

[0088] In some embodiments, combined with Figure 2 and Figure 3 At least a portion of the structure of the baffle body 221 located on both sides of the cyclone chamber 14 along the ash outlet 21 is spaced apart from the inner wall of the dust cup 10, so that the ash storage chamber 13 at least partially surrounds the dust-gas separator 20, for example Figure 3 As shown, the side of the partition body 221 opposite to the pipe section 222 is connected to the inner wall of the dust cup 10, so that the ash storage chamber 13 surrounds the cyclone chamber 14, and the cross-sectional shape of the ash storage chamber 13 is approximately C-shaped. In this way, on the one hand, the volume of the ash storage chamber 13 can be increased to accommodate more dust, hair and other impurities; on the other hand, the airflow circulation area in the ash storage chamber 13 is larger, resulting in higher airflow efficiency. When the cleaning equipment 100 is performing cleaning operations, it helps to reduce airflow loss in the dust collection device 1, thereby improving the dust collection effect.

[0089] In some embodiments, reference Figure 3 The partition body 221 includes a first side portion 2211 facing the air inlet 11 along the opening direction of the air inlet 11 and a second side portion 2212 facing away from the air inlet 11. That is, the first side portion 2211 and the second side portion 2212 are radially opposite each other in the cyclone cavity 14. The second side portion 2212 is connected to the side wall of the dust cup 10 opposite to the air inlet 11. The area of ​​the partition body 221 other than the second side portion 2212 is separated from the dust cup 10. Thus, the cross-sectional shape of the ash storage cavity 13 is approximately C-shaped. On the one hand, it can increase the volume of the ash storage cavity 13 to accommodate more dust, hair and other impurities. On the other hand, the airflow circulation area in the ash storage cavity 13 is larger, which makes the airflow circulation efficiency higher. When the cleaning equipment 100 performs cleaning operations, it helps to reduce the loss of airflow in the dust collection device 1, thereby improving the dust collection effect.

[0090] In some embodiments, reference Figure 2 The ash-throwing port 21 includes a first boundary 211 and a second boundary 212 that are circumferentially opposite to each other along the cyclone cavity 14. The distance between the first boundary 211 and the air inlet 11 along the opening direction of the air inlet 11 is less than the distance between the second boundary 212 and the air inlet 11. The first boundary 211 is arranged opposite to the air inlet 11.

[0091] By adjusting the position of the ash-throwing port 21 on the dust-air separation component 20 along the circumference of the cyclone chamber 14, the distance between the ash-throwing port 21 and the inner wall of the dust cup on the side of the air inlet 11 can be adjusted, so that dust, hair and other debris can more easily enter the ash storage chamber 13 from the ash-throwing port 21, and the internal air passage of the dust collection device 1 is smoother.

[0092] In some embodiments, combined with Figure 1 and Figure 2The 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 be connected to 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.

[0093] In some possible embodiments, the ash outlet 16 can be used to connect to the cleaning base station 200, that is, the dust collection device 1 can be self-cleaned through the cleaning base station 200.

[0094] 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 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 200.

[0095] 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 cover plate 60, so that the cover plate 60 opens the dust outlet 16 and blows the dust and impurities in the dust collection device 1 into the cleaning base station 200. The first rotation direction and the second rotation direction are opposite.

[0096] 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 cover plate 60 from one side of the cleaning base station 200, causing the cover plate 60 to open the dust outlet 16 and suck the dust in the dust collection device 1 into the cleaning base station 200.

[0097] In this way, by cleaning the dust collection device 1 through the cleaning base station 200, the user can be spared the need to manually clean the dust collection device 1, thereby improving cleaning efficiency and effectiveness.

[0098] Of course, in addition to the above-mentioned method of opening and closing the cover 60 and the flexible sealing member by the suction force of the cleaning device 100 and the cleaning base station 200, 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.

[0099] 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.

[0100] Optionally, refer to Figure 4 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 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.

[0101] 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.

[0102] In one possible implementation method, refer to Figure 4 The locking part 152 has a latching protrusion, and the stop hook part 61 is generally 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 is in close contact with the outer surface of the latching protrusion to achieve mechanical locking and ensure that the cover 60 will not be easily opened during use.

[0103] In one possible implementation method, refer to Figure 4 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 61. 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.

[0104] 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.

[0105] 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.

[0106] In one possible implementation method, combining Figure 1 , Figure 2 as well as Figure 4 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 from between the end of the cover plate 60 and the end of the dust cup 10.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In one possible implementation method, combining Figure 1 , Figure 2 as well as Figure 5Along the axial direction of the dust cup 10, from the top to the bottom of the filter cylinder 31, the outer diameter of the filter cylinder 31 gradually decreases. This structure makes the filter cylinder 31 roughly a conical tube sealed at one end. Hair and other debris wrapped around the outer wall of the filter cylinder 31 can leave the outer wall of the filter cylinder 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 cylinder 31.

[0111] In one possible implementation, the longitudinal section of the filter cartridge 31 is U-shaped.

[0112] 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.

[0113] In one possible implementation method, combining Figure 1 , Figure 2 as well as Figure 5 The top of the filter cartridge 31 has a connecting part 32, which is connected to the inner wall of the dust cup 10. The interior of the connecting part 32 forms an air passage cavity 321, which connects the filter cavity 311 and the air outlet 12. The connecting part 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 2 As shown, the top end of the dust-air separator 20 can abut against the bottom end of the connecting part 32 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 and Figure 2 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 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.

[0121] 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.

[0122] In one possible implementation method, refer to Figure 1 and Figure 3 As shown, the dust collection device 1 also includes a dust baffle 50, which is movably disposed at the air inlet 11 and is configured to open and close the air inlet 11.

[0123] The dust baffle 50 is configured to switch between a closed state (closing the air inlet 11) and an open state (opening the air inlet 11) under the influence of airflow. The dust baffle 50 has both open and closed states, effectively controlling airflow and preventing dust leakage.

[0124] When a sufficiently strong airflow enters the air inlet 11, the dust baffle 50 deforms and opens under the thrust of the airflow on the dust baffle 50, opening the air inlet 11. When the airflow stops entering the air inlet 11, the thrust of the airflow on the dust baffle 50 disappears, and the dust baffle 50 returns to the closed state under its own elastic restoring force, blocking the air inlet 11 and closing the air inlet 11, so that air and debris cannot enter or escape through the air inlet 11.

[0125] By closing the air inlet 11 with the dust baffle 50, the dust baffle 50 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.

[0126] In one possible implementation, the dust baffle 50 is a thin-walled structure. The first end of the dust baffle 50 is connected to the inner wall of one side of the air inlet 11, and the second end of the dust baffle 50 is movably abutted against the inner wall of the other side of the air inlet 11. When the airflow pushes the dust baffle 50, a gap appears between the second end of the dust baffle 50 and the inner wall of the other side of the air inlet 11, thereby enabling air intake.

[0127] refer to Figure 3 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.

[0128] 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.

[0129] 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.

[0130] This application embodiment also provides a cleaning system 1000, which includes the cleaning device 100 and the cleaning base station described above. The cleaning base station 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.

[0131] When using the cleaning base station to clean and remove dust from the dust collection device 1, the cover plate 60 can be opened manually first to open the dust outlet 16. In this way, the cleaning base station can clean the dust storage chamber 13 and the cyclone chamber 14 at the same time. It can remove the dust and impurities collected in the dust 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.

[0132] Thus, the cleaning system 1000 of this embodiment can use the cleaning base station to clean the dust collection chamber 13 and the 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 are adhered to the inner wall of the cyclone chamber 14, wrapped around the outer wall of the filter assembly 30, and blocked in the filter hole 312, thus ensuring the suction power of the cleaning device 100 and ensuring the cleaning effect of the cleaning device 100.
