[0039] Reference Figure 1-8 The present invention provides a dust cup assembly 100, including a first-level dust cup assembly 10 and a second-level dust cup assembly 20. The first-level dust cup assembly 10 includes a first separation chamber 13 and a first dust collecting chamber 14. The dust cup assembly 100 also includes a first cyclone separator 18. The first cyclone separator 18 is arranged in the first separation chamber 13. The side wall of the first separation chamber 13 is provided with a first air inlet 16 and a first dust outlet 15. The top or bottom of the first separation chamber 13 is provided with a first exhaust port 17. The first dust collecting chamber 14 is provided at the first The separation chamber 13 has a side with a first dust disposal port 15; the secondary dust cup assembly 20 includes a second separation chamber 21 and a second dust collecting chamber 26. The second separation chamber 21 is arranged on the side of the first dust cup assembly 10 having a first exhaust port 17. The secondary dust cup assembly 20 includes a second cyclone separator. The second cyclone separator is arranged in the second separation chamber 21. The second separation chamber 21 includes a second air inlet, a second dust exhaust port and a second exhaust port 37. The second air inlet is connected to the first exhaust port 17, and the second dust exhaust port faces the second dust collecting chamber 26.

[0040] The dust cup assembly 100 is applied to a cleaning device 1, such as Figure 1As shown, the fan assembly 300 is running, and the dirty dust gas sucked by the dust collecting assembly 400 enters the first separation chamber 13 from the first inlet and moves toward the first cyclone separator 18. The gas and dust are separated under the centrifugal action of the first cyclone separator 18, and the gas is discharged outward through the first exhaust port 17 through the first cyclone separator 18, and the dust passes through the first cyclone separator 18 through the first dust removal port 15 to reach the first dust collecting chamber 14, and is collected in the first dust collecting chamber 14; the gas discharged through the first exhaust port 17 enters the second separation chamber 21 from the second gas inlet and moves toward the second cyclone separator. The gas and dust are separated again under the centrifugal action of the second cyclone separator, and the gas is discharged outward through the second cyclone separator through the second exhaust port 37, and the dust is concentrated in the second dust collecting chamber 26 through the second cyclone separator through the second dust exhaust port. By setting a first-level dust cup assembly 10 and a second-level dust cup assembly 20, and connecting the first exhaust port 17 of the first-level dust cup assembly 10 with the second air inlet of the second-level dust cup assembly 20, the dust and gas can pass through the first-level dust cup assembly 10 and the second-level dust cup assembly 20 in sequence, that is, two dust and gas separations are performed. The separation targets of the first cyclone separator 18 and the second cyclone separator can also be specifically distinguished, so that they can target dust with larger and smaller particle sizes respectively. Therefore, it can not only improve the separation efficiency of the vacuum cleaner, but also ensure the smooth operation of the vacuum cleaner.

[0041] In one embodiment, the first separation chamber 13 is disposed in the first dust collecting chamber 14, and the central axis of the first separation chamber 13 is eccentrically disposed with respect to the central axis of the first dust collecting chamber 14. Specifically, the central axis of the first dust collecting chamber 14 is the first central axis 11a, and the central axis of the first separation chamber 13 is the second central axis 12a, that is, the first central axis 11a and the second central axis 12a are eccentrically disposed. Since the first separation chamber 13 is disposed in the first dust collecting chamber 14 and the first central axis 11a and the second central axis 12a are eccentrically disposed, the space of the first dust collecting chamber 14 can be concentrated toward one side of the first separation chamber 13, and the first ash disposal port 15 is disposed corresponding to one side of the first dust collecting chamber 14. This can increase the volume of the first dust collecting chamber 14 near the first ash disposal port 15 on the periphery of the first separation chamber 13, thereby further improving the utilization of the first dust collecting chamber 14 on the periphery of the first separation chamber 13, and further improving the effective utilization rate of the first dust collecting chamber 14.

[0042] In addition, since the first center axis 11a and the second center axis 12a are eccentrically arranged, the distance from the first ash throwing port 15 to the side wall of the first dust collecting chamber 14 can be increased while the radial dimensions of the first separation chamber 13 and the first dust collecting chamber 14 remain unchanged. Therefore, when the spiral gas moving toward the first ash throwing port 15 enters the first dust collecting chamber 14 through the first ash throwing port 15, the ash centrifugally separated in the first cyclone separator 18 is more likely to enter the first dust collecting chamber 14 from the first ash throwing port 15, and it is also difficult for the first ash throwing port 15 to form an air flow vortex.

[0043] In one embodiment, the primary cyclone separator is a conical filter screen, the open end of which is connected to the first exhaust port 17. The conical filter screen is a conical structure formed by a filter screen with one end open. The open end of the conical filter screen is arranged corresponding to the first exhaust port 17, and the diameter of the conical filter screen is gradually reduced from the end adjacent to the first exhaust port 17 to the end away from the first exhaust port 17. Dust and gas in the first separation chamber 13 whose volume is smaller than the filter screen mesh are discharged to the outside through the conical filter screen.

[0044] In one embodiment, the secondary dust cup assembly 20 is disposed outside the primary dust cup assembly 10. In this way, each component in the primary dust cup assembly 10 is sealed separately, each component in the secondary dust cup assembly 20 is sealed separately, and the primary dust cup assembly 10 and the secondary dust cup assembly 20 are sealed again. Compared with the sealing method of disposing the secondary dust cup assembly 20 inside the primary dust cup assembly 10, this sealing method can reduce the sealing from inside, middle and outside to two layers, which can greatly reduce the sealing difficulty. At the same time, there is no counter-flow of airflow on the movement route, so there is no need for stratification, which can save vertical height and achieve higher volume utilization.

[0045] In one embodiment, the first-stage dust cup assembly 10 includes an outer cylinder 11 whose inner cavity is formed as a first dust collecting chamber 14 and an inner cylinder 12 whose inner cavity is formed as a first separation chamber 13. The outer cylinder 11 is formed with a semi-enclosed receiving chamber 19 below the inner cylinder 12, and the second-stage dust cup assembly 20 is arranged in the semi-enclosed receiving chamber 19.

[0046] Specifically, because the first separation chamber 13 is disposed within the first dust collection chamber 14, and the central axes of the two are eccentrically disposed, the inner cylinder 12 is also disposed within the outer cylinder 11, and the central axes of the two are eccentrically disposed. Optionally, the inner cylinder 12 and the outer cylinder 11 are integrally formed. Of course, in other embodiments, the inner cylinder 12 can also be welded to the outer cylinder 11 or connected via other fasteners.

[0047] By forming a semi-enclosed receiving chamber 19 for accommodating the secondary dust cup assembly 20 under the outer cylinder 11, the outer cylinder 11 can be used to fix the secondary dust cup assembly 20, that is, the relative fixation of the primary dust cup assembly 10 and the secondary dust cup assembly 20 is achieved, thereby further improving the structural stability of the dust cup assembly 100.

[0048] In the above structure, since the secondary dust cup assembly 20 is arranged below the inner cylinder 12, the first exhaust port 17 is arranged at the bottom of the inner cylinder 12, that is, the first exhaust port 17 is arranged at the bottom of the first separation chamber 13, so that the flow direction of the gas and dust is the same, that is, both flow downward, which can further save the vertical space of the dust cup assembly 100.

[0049] Of course, in other embodiments, the outer cylinder 11 can also form a semi-enclosed receiving chamber 19 above the inner cylinder 12 for accommodating the secondary dust cup assembly 20. In this way, the first exhaust port 17 is arranged at the top of the inner cylinder 12, that is, the first exhaust port 17 is arranged at the top of the first separation chamber 13. At this time, the gas flows upward and the dust flows downward.

[0050] In one embodiment, the first dust collecting chamber 14 includes a first arc-shaped chamber 141 arranged along the circumference of the first separation chamber 13 and a second arc-shaped chamber 142 arranged along the circumference of the second separation chamber 21 , and the first arc-shaped chamber 141 and the second arc-shaped chamber 142 are connected.

[0051] Specifically, the first arc-shaped chamber 141 is arranged on the side of the first separation chamber 13 corresponding to the first ash outlet 15, and the second arc-shaped chamber 142 is arranged directly below the first arc-shaped chamber 141. In this way, after the dust enters the first arc-shaped chamber 141 from the first ash outlet 15 of the first separation chamber 13, it gathers in the second arc-shaped chamber 142 under the action of gravity.

[0052] This embodiment divides the first dust collecting chamber 14 into a first arc-shaped chamber 141 and a second arc-shaped chamber 142, so that the first dust collecting chamber 14 can extend downward to the periphery of the secondary dust cup assembly 20, which not only increases the space of the first dust collecting chamber 14, but also makes the space more compact, thereby further improving space utilization.

[0053] Optionally, on a section formed by the central axis of the inner cylinder 12 and the central axis of the outer cylinder 11, the width of the first arc-shaped chamber 141 is smaller than the width of the second arc-shaped chamber 142. That is, by rationally allocating the space occupied by the second arc-shaped chamber 142 and the secondary dust cup assembly 20, the volume of the first dust collecting chamber 14 is increased.

[0054] In one embodiment, the second cyclone separator is a cyclone cone 22 , and there are multiple cyclone cones 22 . The multiple cyclone cones 22 are arranged in an arc shape around the outer periphery of the first exhaust port 17 .

[0055] Specifically, the cyclone cone 22 is a conical tube with a cyclone passage formed therein. The small end of the conical tube serves as a dust outlet, and the large end serves as an air outlet 27. The sidewall of the conical tube is also provided with an air inlet 23 arranged tangentially thereto. The conical tube is configured to form a spiral airflow from the air inlet 23 toward the dust outlet. The cyclone cone 22 is arranged with the air outlet 27 facing upward and the dust outlet facing downward. The air inlet 23 is connected to the second air inlet, the air outlet 27 is connected to the second exhaust port 37, and the dust outlet is connected to the second dust collecting chamber 26. In this way, gas entering the second separation chamber 21 through the second air inlet enters the cyclone cone 22 through the air inlet 23. Under the cyclonic separation action of the cyclone cone 22, dust is discharged into the second dust collecting chamber 26 through the dust outlet, and gas enters the second exhaust port 37 through the air outlet 27.

[0056] There are multiple cyclone cones 22, and the multiple cyclone cones 22 are connected to the same bow plate 24 in an arc shape, and the air inlet 23 of each cyclone cone 22 is set towards the central axis of the arc plate. At the same time, a rib 25 with the same height as the upper end of the cyclone cone 22 is formed on the periphery of the arc plate. Part of the rib 25 and the multiple cyclone cones 22 enclose a central cavity connected to the air inlet 23 of the cyclone cone 22, and a second air inlet is formed at the upper end of the central cavity.

[0057] In one embodiment, an air duct cover 30 is further included, and the air duct cover 30 is provided with a first air passage 35 and a second air passage 36. The first air passage 35 is connected between the first exhaust port 17 and the second air inlet, and the second air passage 36 is connected between the second cyclone separator and the second exhaust port 37.

[0058] Specifically, the air duct cover 30 is adapted to the shape of the bow plate 24, and the air duct cover 30 is formed with a first air outlet 31, multiple second air outlets 32 arranged circumferentially along the first air outlet 31, and a second exhaust outlet 37 arranged outside the second air outlet 32. The air duct cover 30 is also formed with a first side wall 33 on the periphery of the first air outlet 31, and the inner cavity of the first side wall 33 is formed as a first air passage 35. The air duct cover 30 is formed with a second side wall 34 on the periphery, and the second air outlet 32 ​​and the second exhaust outlet 37 are located between the first side wall 33 and the second side wall 34, and the cavity between the first side wall 33 and the second side wall 34 is formed as a second air passage 36.

[0059] The upper end surface of the air duct cover 30 is sealed with the bottom wall of the inner tube 11, and the lower end surface of the air duct cover 30 is sealed with the upper surface of the multiple cyclone cones 22. In this way, the upper end of the first air passage 35 is connected to the first exhaust port 17, the lower end of the first air passage 35 is connected to the second air inlet, the lower end of the second air passage 36 is connected to the air outlets 27 of the multiple cyclone cones 22 respectively, and the upper end is connected to the second exhaust port 37.

[0060] In one embodiment, the inner cylinder 12 and the outer cylinder 11 share a common sidewall, and the first dust removal opening 15 is formed on the shared sidewall. By making the sidewall of the inner cylinder 12 adhere to the inner wall of the outer cylinder 11, the space around the inner cylinder 12 can be concentrated to one side to the greatest extent, thereby maximizing the effective utilization of the first dust collection chamber 14.

[0061] In one embodiment, the first air inlet 16 is disposed on the side of the inner cylinder 12 opposite the shared sidewall. The first ash outlet 15 is arranged in an arc shape radially relative to the dust cup. Specifically, the upper edge of the first ash outlet 15 extends to the upper edge of the inner cylinder 12. This arc shape of the first ash outlet 15 radially relative to the dust cup increases its surface area, facilitating the entry of larger particles into the first dust collection chamber 14.

[0062] A second aspect of the present invention further provides a cleaning device 1, comprising a fan assembly 300, a dust collection assembly 400, and a dust cup assembly 100 as described above. The first air inlet 16 is connected to the outlet of the dust collection assembly 400, and the second air outlet 37 is connected to the inlet of the fan assembly 300. The structure of the dust cup assembly 100 is similar to that of the above-described embodiments. Since the cleaning device 1 in this embodiment includes the above-described dust cup assembly 100, it has at least the beneficial effects of the above-described embodiments.

[0063] Specifically, the cleaning device 1 also includes a handle 200 and a floor brush assembly 500 mounted at the lower end of the handle 200. The fan assembly 300 is mounted below the dust cup assembly 100 and is mounted together above the floor brush assembly 500. The dust collection assembly 400 includes a hose, one end of which is connected to the floor brush assembly 500 and the other end is connected to the first air inlet 16 of the dust cup assembly 100. When the cleaning device 1 is in operation, the dirty dust near the floor brush assembly 500 is sucked by the fan assembly 300 and passes through the dust collection assembly 400, the dust cup assembly 100, and the fan assembly 300 in sequence, and is finally discharged from the fan outlet 600. Furthermore, a filter cotton 40 is provided between the fan outlet 600 and the second exhaust port.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
