[0077] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0078] Vacuum cleaners and other cleaning equipment use high-speed motors to generate powerful airflow, which draws dust and air into the cleaning equipment. The dust is then separated from the airflow by a dust filter. The purified air is then released back into the environment, improving environmental cleanliness and air quality.

[0079] In some cleaning equipment, although the filter cartridge inside the cyclone chamber can effectively filter some larger dust, hair and other impurities, hair is easy to get tangled on the outer wall of the filter cartridge, and dust is easy to clog the filter holes of the filter cartridge. This not only affects the filtration effect and causes the suction power of the cleaning equipment to decrease, but also makes it difficult to clean the filter cartridge, affecting the cleaning work.

[0080] The dust cup assembly and cleaning device provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0081] The present invention provides a cleaning device, including but not limited to a vacuum cleaner.

[0082] refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a dust cup assembly, including: a dust cup 10, a baffle 20, and a dust filter assembly 30. The dust cup 10 has a hollow cavity inside, with an air inlet 11 and an air outlet 12. The baffle 20 is disposed inside the dust cup 10, dividing the interior of the dust cup 10 into a dust storage chamber 13 and a cyclone chamber 14. A dust-throwing port 21 is provided inside the baffle 20, connecting 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 communicates with the cyclone chamber 14. The dust filter assembly 30 is disposed inside the dust cup 10, and includes a filter cylinder 31 extending into the cyclone chamber 14 to separate dust and gas in the airflow entering the cyclone chamber 14. Along the axial direction of the dust cup 10, the air inlet 11 is closer to the air outlet 12 than the dust-throwing port 21. The axial direction of the dust cup 10 is referred to as... Figure 5 The arrow Y in the diagram indicates the direction.

[0083] The dust cup assembly provided in this embodiment of the utility model has a baffle 20 that divides the interior of the dust cup 10 into a dust storage chamber 13 and a cyclone chamber 14. The baffle 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 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.

[0084] refer to Figure 5The direction indicated by the arrow K in the figure is the flow direction of the air flow in the cyclone cavity 14. When the dust, hair and other impurities in the air enter the cyclone cavity 14 from the air inlet 11, the impurities are subjected to the double action of the cyclone centrifugal force and the gravity of the impurities, wherein the cyclone centrifugal force makes the impurities move along the inner wall of the cyclone cavity 14 in a circular manner, reducing the phenomenon of the impurities accumulating on the surface of the filter cylinder 31 in the cyclone cavity 14, and reducing the problem of the filter hole 312 of the filter cylinder 31 being blocked. The dust and other impurities are subjected to the action of their own gravity and move downward in the cyclone cavity 14. When the dust and impurities move to the dust throwing port 21 under the combined action of gravity and centrifugal force, the impurities are thrown into the dust storage cavity 13 from the dust throwing port 21, improving the separation effect of the dust and other impurities from the air, reducing the problem of the hair and other impurities winding around the surface of the filter cylinder 31 in the cyclone cavity 14, making the filter cylinder 31 not easy to be blocked, and enabling the cleaning device to maintain stable suction, ensuring the cleaning efficiency and reducing the frequency of the user cleaning the filter cylinder 31.

[0085] The dust cup assembly provided by the embodiment of the utility model can make most of the dust and other impurities separate from the air and be collected into the dust storage cavity 13 before entering the filter cylinder 31 under the combined action of gravity and centrifugal force, thereby reducing the burden of the filter cylinder 31. Most of the dust and other impurities are collected in the dust storage cavity 13, and the user only needs to empty the dust storage cavity 13 regularly, thereby reducing the frequent cleaning of the filter cylinder 31.

[0086] In a possible implementation manner, referring to FIGS. 1 to 3, Figure 4 、 Figure 5 and Figure 6 , the dust cup 10 and the wind blocking piece 20 can be an integral structure connected integrally, which helps to improve the structural strength of the connection.

[0087] In a possible implementation manner, the dust cup 10 can be made of transparent material, so that the user can directly observe the dust storage condition in the dust storage cavity 13 and clean it in time.

[0088] In a possible implementation manner, the dust throwing port 21 includes but is not limited to a rectangular shape, a circular shape and the like. The air inlet 11 includes but is not limited to a rectangular shape, a trapezoidal shape and the like.

[0089] In a possible implementation manner, the dust throwing port 21 and the air inlet 11 are located at different side walls of the cyclone cavity 14, respectively, and the central axis of the dust throwing port 21 and the central axis of the air inlet 11 have an included angle. Such a structure helps to optimize the air flow path and more effectively utilize the cyclone effect to separate dust particles from the air.

[0090] In a possible implementation, the angle between the central axis of the dust ejection port 21 and the central axis of the air inlet port 11 can be 80°, 90°, 120°, etc. The dust and other sundries entering the cyclone cavity 14 from the air inlet port 11 are subjected to the action of cyclone centrifugal force, and the heavier dust and other sundries are thrown to the inner wall of the cyclone cavity 14 and discharged into the dust storage cavity 13 through the dust ejection port 21.

[0091] The central axis of the dust ejection port 21 refers to an imaginary straight line passing through the center of the dust ejection port 21 and extending in the depth direction of the dust ejection port 21, and the central axis of the air inlet port 11 refers to an imaginary straight line passing through the center of the air inlet port 11 and extending in the depth direction of the air inlet port 11.

[0092] In a possible implementation, the air blocking member 20 includes a side partition plate 22 and a bottom partition plate 23. The side partition plate 22 is connected between the inner wall surfaces of the opposite sides of the dust cup 10, and the bottom partition plate 23 is connected to the side partition plate 22 and blocks the end of the cyclone cavity 14 away from the air outlet port 12. The dust ejection port 21 is formed in the side partition plate 22, and part of the bottom partition plate 23 forms the inner wall surface of the dust ejection port 21. Such a structure makes the side bottom end of the dust ejection port 21 flush with the bottom partition plate 23, which is conducive to the smooth discharge of the dust and other sundries separated in the cyclone cavity 14 through the dust ejection port 21 and ensures the smoothness of the dust and other sundries entering the dust storage cavity 13 from the dust ejection port 21.

[0093] The side partition plate 22 separates the hollow cavity inside the dust cup 10 into the dust storage cavity 13 and the cyclone cavity 14 adjacent to each other by its blocking effect, and can guide the airflow to form a rotating motion in the cyclone cavity 14. The dust ejection port 21 is formed in the side partition plate 22, which is conducive to the dust and other sundries separated in the cyclone cavity 14 entering the dust storage cavity 13 through the dust ejection port 21.

[0094] The bottom partition plate 23 blocks the end of the cyclone cavity 14 away from the air outlet port 12, ensures the formation of an effective rotating path of the airflow in the cyclone cavity 14, and is conducive to increasing the separation efficiency of the dust and other sundries and air.

[0095] In a possible implementation, the side partition plate 22 is in a circular arc shape, so that the cyclone cavity 14 is close to a cylindrical shape.

[0096] In a possible implementation, the bottom partition plate 23 is in a horizontal panel shape.

[0097] In a possible implementation, the filter cylinder 31 has a filter cavity 311 formed inside, and the side wall of the filter cylinder 31 is provided with a plurality of filter holes 312 communicating between the cyclone cavity 14 and the filter cavity 311.

[0098] The filter cartridge 31 is used to preliminarily filter the dust and sundries blocked into the cyclone cavity 14, and can effectively remove sundries with large particles. The air filtered by the filter cartridge 31 enters the filter cavity 311 through the filter holes 312. The filter cavity 311 is a space inside the filter cartridge 31, used to accommodate the filtered air. The filter holes 312 are passages between the filter cavity 311 and the cyclone cavity 14, allowing the air to pass through while blocking the sundries with large particles, thereby achieving the filtering effect.

[0099] In a possible implementation, the number of the filter holes 312 and the inner diameter of the filter holes 312 are not specifically limited. The plurality of filter holes 312 can be arranged along the circumferential side of the filter cartridge 31. The design of the plurality of filter holes 312 increases the effective filtering area, thereby improving the filtering efficiency and making the discharged air cleaner.

[0100] In a possible implementation, along the axial direction of the dust cup 10, from the top end of the filter cartridge 31 to the bottom end of the filter cartridge 31, the outer diameter of the filter cartridge 31 gradually decreases. Such a structure makes the filter cartridge 31 substantially a conical pipe column with one end sealed. The sundries such as hair wrapped around the outer wall of the filter cartridge 31 can leave the outer wall of the filter cartridge 31 from the end with smaller outer diameter of the filter cartridge 31, thereby facilitating the cleaning of the sundries such as hair wrapped around the outer wall of the filter cartridge 31.

[0101] In a possible implementation, the longitudinal section of the filter cartridge 31 is in the shape of “U”.

[0102] The bottom end of the filter cartridge 31 is in a closed structure. The closed structure can block the airflow from directly entering the filter cavity 311 without being filtered by the filter cartridge 31, effectively control the airflow path, ensure that all the air is filtered by the filter cartridge 31, effectively protect other filtering structures downstream of the airflow path, and improve the dust removal effect.

[0103] In a possible implementation, as shown in Figure 3 , Figure 5 and Figure 6 , the top end of the filter cartridge 31 has a connecting portion 32 connected to the inner wall of the dust cup 10. The connecting portion 32 encloses an air passing cavity 321 inside. The air passing cavity 321 is connected between the filter cavity 311 and the air outlet 12. The connecting portion 32 is used to fix the filter cartridge 31 to the inner wall of the dust cup 10, thereby ensuring the stability of the fixation of the filter cartridge 31 in the dust cup 10.

[0104] In a possible implementation, as shown in Figure 2 , Figure 3 and Figure 5As shown, the wind shield 20 further comprises a platform portion 24 connected to the side partition 22 at an end away from the bottom partition 23, and the bottom end of the connecting portion 32 abuts against the platform portion 24. The platform portion 24 serves to support the connecting portion 32, thereby improving the stability of the fixing of the filter cartridge 31.

[0105] In a possible implementation, the connecting portion 32 and the inner wall surface of the dust cup 10 can be connected through snap connection or interference fit connection.

[0106] In a possible implementation, the connecting portion 32 can be in the shape of a basin, and the filter cartridge 31 and the connecting portion 32 can be in an integral structure or a split structure.

[0107] In a possible implementation, referring to Figure 3 and Figure 5 As shown, the dust filtering assembly 30 further comprises at least one first filter 40 arranged in the air passing cavity 321.

[0108] In a possible implementation, the number of the first filters 40 can be two or more, thereby improving the filtering effect. The plurality of first filters 40 can be of the same material or different materials.

[0109] In a possible implementation, the dust filtering assembly 30 comprises two first filters 40, which are sponge and hepa respectively. The sponge is arranged on the side close to the filter cartridge 31, and the hepa is arranged on the side close to the air outlet 12. The hepa can filter 0.3 μm small dust particles, so that the discharged air is cleaner.

[0110] In a possible implementation, the dust cup assembly further comprises a flow guide 50 arranged between the first filter 40 and the filter cartridge 31. The flow guide 50 comprises a first flow guide plate 51 and a second flow guide plate 52 connected to the edge of the first flow guide plate 51. The center of the first flow guide plate 51 protrudes into the filtering cavity 311, and the second flow guide plate 52 horizontally expands along the circumferential side of the first flow guide plate 51 in the air passing cavity 321.

[0111] The flow guide 50 serves to disperse and guide the airflow, so that the airflow flowing from the inside of the filter cartridge 31 to the first filter 40 is dispersed, the flow path of the airflow is increased, the airflow in the filtering cavity 311 does not vertically impact the first filter 40, the dust and other impurities are not directly attached to the first filter 40, the problems of deformation of the first filter 40 caused by airflow impact, easy blocking and noise are solved.

[0112] In one possible implementation, the first guide plate 51 has a cross-section in the shape of a "V", and the center of the first guide plate 51 protrudes into the filtering cavity 311, guiding the airflow to pass between the periphery of the first guide plate 51 and the inner wall of the filtering cavity 311. When the airflow in the filtering cavity 311 encounters the first guide plate 51, the first guide plate 51 can change the direction of the airflow, causing the airflow to disperse, so that the airflow is dispersed and buffered before entering the first filter 40 from the filtering cavity 311, rather than directly impacting the first filter 40 at high speed and high pressure, which helps to reduce the wear and noise of the first filter 40, ensures the service life of the first filter 40, and reduces the maintenance and replacement frequency of the first filter 40.

[0113] The second guide plate 52 is connected to the edge of the first guide plate 51 and horizontally extends along the side of the first guide plate 51 in the air passage 321. The second guide plate 52 is used to further guide the airflow, ensuring that the airflow flows along a longer path before entering the first filter 40, so that the airflow has more opportunities to contact the first filter 40, which helps the first filter 40 to capture more dust and other impurity particles.

[0114] In one possible implementation, referring to Figure 2 , the cross-section of the cyclone cavity 14 is circular or elliptical in the axial direction perpendicular to the dust cup 10.

[0115] The circular or elliptical cross-section helps to form a smooth and continuous rotational airflow, which can maximize the effect of centrifugal force, making dust and other impurities more effectively thrown to the edge of the cyclone cavity 14, thereby improving the efficiency of air-dust separation. The circular or elliptical cross-section also reduces the generation of vortex and turbulence, reduces energy loss, and thus maintains the stability of the airflow and the high efficiency of the cleaning device.

[0116] In one possible implementation, referring to Figure 5 and Figure 6 , the dust cup assembly further includes a dust dumping cover 60, which is located at opposite ends of the dust cup 10 along the axial direction of the dust cup 10, respectively with the air outlet 12.

[0117] In this example, the dust dumping cover 60 and the air outlet 12 are located at the two ends of the dust cup 10 in the axial direction, and the air outlet 12 is used to discharge filtered air, which helps to ensure that the air smoothly exits the dust cup assembly through the air outlet 12, reducing air resistance and improving overall efficiency. The dust dumping cover 60 can be opened to empty the dust accumulated in the dust storage cavity 13, facilitating maintenance and cleaning.

[0118] With this design, the user can easily open the dust storage cavity 13 to dump the collected dust and particles, keeping the cleaning device clean and efficient.

[0119] In one possible implementation, one side of the dust cover 60 is hinged to the dust cup 10, and the other side of the dust cover 60 is mechanically locked to the dust cup 10.

[0120] In one possible implementation method, refer to Figure 5 , Figure 6 and Figure 7 As shown, the dust cup assembly also includes an operation button 15, which is disposed on the dust cup 10. The operation button 15 includes a locking part 152. The dust cover 60 has a hook part 61. The operation button 15 is movably disposed on the outer wall of the dust cup 10 so that the locking part 152 extends into the hook part 61.

[0121] The user operates the control button 15 to lock and release the dust collection cover 60. The locking part 152 extends into the hook part 61 to lock the dust collection cover 60, making it difficult to open and improving the stability of its closure, thus preventing dust leakage from the ash storage chamber 13. When the locking part 152 disengages from the hook part 61, the dust collection cover 60 is released, allowing it to be opened and used to clean dust and debris from the ash storage chamber 13.

[0122] In one possible implementation, the locking part 152 typically has a protrusion, and the hook part 61 is typically a recessed structure. The hook part 61 is designed to accommodate the size and shape of the protrusion to ensure that the protrusion can be smoothly inserted into the hook part 61 and remain stable. When the protrusion extends into the hook part 61, the inner wall of the hook part 61 is in close contact with the outer surface of the protrusion, achieving mechanical locking and ensuring that the dust cover 60 will not be easily opened during use.

[0123] In one possible implementation, the operating button 15 further includes a pressing part 151 and a rotating part 153. The pressing part 151 is connected to one end of the locking part 152 relative to the hook part 61, and the rotating part 153 is disposed at the connection position of the pressing part 151 and the locking part 152. The operating button 15 is rotatably disposed on the dust cup 10 via the rotating part 153.

[0124] 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 dust cover 60.

[0125] 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 hook portion 61 to achieve the locking effect of the dust cover 60.

[0126] In a possible implementation, a sealing ring 62 is arranged between the dust pouring cover 60 and the end of the dust cup 10 to prevent dust leakage between the dust pouring cover 60 and the end of the dust cup 10.

[0127] In a possible implementation, referring to Figure 4 As shown in the figure, the dust cup assembly further includes a dust blocking member 70 movably arranged in the air inlet 11, and the dust blocking member 70 is configured to open and close the air inlet 11.

[0128] The dust blocking member 70 is configured to switch between a closed state of closing the air inlet 11 and an open state of opening the air inlet 11 under the action of the airflow. The dust blocking member 70 has two states of opening and closing, and has the effects of controlling the entry of the airflow and preventing dust leakage.

[0129] When the airflow with sufficient strength enters the air inlet 11, the dust blocking member 70 is deformed to the open state under the pushing force of the airflow on the dust blocking member 70, and the air inlet 11 is opened; when the airflow stops entering the air inlet 11, the pushing force of the airflow on the dust blocking member 70 disappears, and the dust blocking member 70 is reset to the closed state under the elastic restoring force of itself, and the air inlet 11 is blocked, thereby closing the air inlet 11, so that air and sundries cannot enter or escape through the air inlet 11.

[0130] By closing the air inlet 11 through the dust blocking member 70, the dust blocking member 70 prevents the dust and sundries in the cyclone cavity 14 from falling from the air inlet 11, which helps to avoid secondary pollution caused by the cleaning device being closed or moved, and also protects the internal components of the cleaning device from being invaded by dust and sundries from the external environment, thereby prolonging the service life of the cleaning device.

[0131] In a possible implementation, the dust blocking member 70 is a thin-walled structure, the first end of the dust blocking member 70 is connected to one side of the inner wall of the air inlet 11, and the second end of the dust blocking member 70 movably abuts against the other side of the inner wall of the air inlet 11. When the airflow pushes the dust blocking member 70, a gap appears between the second end of the dust blocking member 70 and the other side of the inner wall of the air inlet 11, thereby realizing air inlet.

[0132] Referring to the dashed arrow shown in Figure 4 Air enters the cyclone cavity 14 from the air inlet 11, and the airflow forms a high-speed rotating airflow, which causes dust and sundries to generate centrifugal force under the action of the centrifugal force, and the heavier dust and sundries are thrown to the inner wall surface of the cyclone cavity 14. Figure 4 and Figure 5As shown, due to the gravity of the dust and sundries, the dust and sundries will gradually fall into the dust storage cavity 13, which effectively separates most of the dust and sundries from the airflow, greatly reduces the amount of dust and sundries contained in the air entering the filter cartridge 31, and helps to reduce the problem of hair winding around the outer wall of the filter cartridge 31 and the filter cartridge 31 being blocked.

[0137] The dust cup assembly is detachably arranged in the machine body 81, so that the user can easily remove the dust cup assembly for emptying or cleaning, which helps to improve the use convenience and maintenance efficiency of the cleaning equipment.

[0138] Referring to Figure 10 As shown, the direction indicated by the arrow A is the movement direction of the dust cup assembly from the machine body 81.

[0139] Referring to Figure 8 As shown, the arrow P points to the flow direction of the air, the inlet end of the suction passage 811 is a dust suction port, located at the front end of the machine body 81, and the air inlet 11 of the dust cup assembly is connected to the outlet end of the suction passage 811, so that the air entering the suction passage 811 from the dust suction port enters the air inlet 11 of the dust cup assembly through the outlet end of the suction passage 811.

[0140] The driving member 82 is an electric motor, which is used to provide suction force, so that the air source continuously enters into the air suction channel 811 from the dust suction port, and then enters into the air inlet 11 of the dust cup assembly through the outlet end of the air suction channel 811, the air entering into the cyclone cavity 14 through the air inlet 11 performs spiral upward movement in the cyclone cavity 14, and the impurities are separated through cyclone centrifugal separation and gravity separation and filtering effect of the filter cylinder 31, the air filtered by the filter cylinder 31 enters into the filtering cavity 311, and then is filtered by the first filter 40, and then is discharged from the air outlet 12, so that the dust removal effect is realized.
