[0037] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0038] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0039] Example 1

[0040] A rotatable cyclone cone structure, characterized in that it comprises:

[0041] Support 11 has an internal cavity;

[0042] The filter element 12 fills the cavity of the support 11;

[0043] The cyclone cone 13 is hollow in shape and can be rotatably mounted on the support 11;

[0044] And bearing 14, which is used to rotatably connect cyclone cone 13 and support 11, so that cyclone cone 13 can rotate relative to support 11 under the action of airflow.

[0045] In this embodiment, the bracket 11 includes a lower bracket 111, an upper bracket 112 disposed on the lower bracket 111, and a mounting base 113 disposed on the top of the upper bracket 112. The mounting base 113 has a mounting opening 114, and a bearing 14 is fitted into the mounting opening 114. The outer ring of the bearing 14 is fixedly connected to the inner wall of the mounting opening 114. A lower bracket sealing ring 12 is also provided at the lower part of the bracket 11.

[0046] In this embodiment, the bottom of the cyclone cone 13 is open, and it fits over the upper bracket 112 from top to bottom. The top of the cyclone cone 13 has a downward protrusion forming a mounting post 131. The mounting post 131 has a stepped surface 132. The mounting post 131 is inserted into the inner ring of the bearing 14 and fixedly connected to the inner ring of the bearing 14 by screws 134. The stepped surface is in contact with the inner ring of the bearing 14. This allows the cyclone cone 13 and the inner ring of the bearing 14 to rotate together relative to the upper bracket 112 when subjected to external force.

[0047] In this embodiment, a number of air inlets are densely arranged on the wall of the cyclone cone 13 to allow air to pass through.

[0048] Reference Figure 1 In this embodiment, a number of ribs 135 protruding from the wall surface are provided on the wall surface of the cyclone cone 13 along the inclined direction. The ribs 135 can improve the structural strength of the cyclone cone 13 on the one hand, and on the other hand, when subjected to the action of the swirling airflow, the ribs 135 can serve as the main force-bearing parts, receiving the thrust of the airflow and forcing the cyclone cone 13 to rotate.

[0049] Reference Figures 2-3 In another embodiment, a plurality of grooves 137 recessed into the wall surface are provided on the wall surface of the cyclone cone 13 along the inclined direction.

[0050] In this embodiment, annular retaining rings 136 are provided at intervals around the outer periphery of the mounting post 131. The annular retaining rings 136 cover the outer periphery of the mounting base 113 but do not contact the mounting base 113. The annular retaining rings 136 serve as a barrier, effectively preventing dust in the air from entering the bearing 14 located inside the mounting post 131, while not affecting the rotation of the cyclone cone 13.

[0051] In this embodiment, a sealing ring 15 is provided between the cyclone cone 13 and the support 11. The sealing ring 15 is sleeved on the support 11 and is located between the lower support 111 and the upper support 112. The bottom of the cyclone cone 13 is in flexible contact with the sealing ring 15, which can maintain a good seal during relative rotational movement.

[0052] The rotatable cyclone cone structure 1 in this embodiment can be applied to a dust-gas separation device. Under the action of an external power source, an airflow is formed, and the cyclone cone 13 will rotate relative to the support 11 under the action of the airflow. This makes it easier to clean the cyclone cone 13, as it is less likely to get tangled in hair, fuzz, or other filamentous items, and the dust-gas separation efficiency is higher.

[0053] Example 2

[0054] A dust-gas separation device, comprising:

[0055] Dust cup 2;

[0056] The upper cover 5 and the lower cover 6 are detachably connected to the upper and lower parts of the dust cup 2, respectively;

[0057] Dust-gas separation chamber 3 is formed inside dust cup 2. The interior of dust-gas separation chamber 3 is hollow and a mounting base 31 is formed on its bottom wall.

[0058] Dust collection chamber 4 is formed inside dust cup 2 and is connected to dust-gas separation chamber 3 at the upper end. Dust collection chamber 4 is hollow inside and adjacent to dust-gas separation chamber 3.

[0059] And the rotatable cyclone cone structure 1 in the embodiment, the bracket 11 of the rotatable cyclone cone structure 1 is fixedly installed on the mounting base 31.

[0060] In this embodiment, the mounting base 31 and the inner wall of the dust-gas separation chamber 3 are spaced apart to form an annular cyclone cavity 32 located between the outer periphery of the mounting base 31 and the inner wall of the dust-gas separation chamber 3. The annular cyclone cavity 32 is provided with a guide plate 33 that spirals upward around the mounting base 31 of the filter element 12. The bottom of the dust-gas separation chamber 3 is provided with an exhaust port 34 leading to the bottom of the filter element 12 and an air inlet 35 that is connected to the bottom of the guide plate 33. The air inlet 35 is arranged tangentially relative to the annular cyclone cavity 32 to ensure that the air entering the air inlet 35 is forced to form an airflow that follows a spiral path around the guide plate 33, and the cyclone cone 13 of the rotatable cyclone cone structure 1 rotates relative to the support 11 under the action of the airflow.

[0061] The dust-air separation device of this embodiment can be applied to cleaning appliances such as mite removers or vacuum cleaners. For example, it can be applied to an easy-to-clean mite remover disclosed in patent CN213850456U. The corresponding components can be replaced by the dust-air separation device of this embodiment.

[0062] Taking its application in a mite removal device as an example, the main working principle of this embodiment is as follows:

[0063] During cleaning, the mite remover's power source generates a negative pressure inside the cyclone chamber through the exhaust port 34. The dirty airflow drawn in by the mite remover's nozzle enters the cyclone chamber through the air inlet 35. Guided by the air guide plate 33, this dirty airflow is forced to follow a spiral upward path around the annular cyclone cavity 32, thus forming a dirty airflow cyclone within the annular cyclone cavity 32. This swirling airflow forces the cyclone cone 13 to rotate at high speed relative to the support 11, causing hair, lint, and other filamentous items in the dirty air to fall onto the surface of the cyclone cone 13 and be shaken off, preventing them from becoming entangled. 3. This design improves dust and air separation efficiency and makes cleaning easier. Larger dust particles are thrown into the dust collection chamber 4 through the dust throwing port and deposited at the bottom of the dust collection chamber 4. Smaller dust particles are filtered by the filter element 12 and retained in the cyclone chamber. The retained small dust particles are thrown into the dust collection chamber 4 along with the subsequent dirty air flow cyclone. The clean air flow filtered by the filter element 12 is drawn out of the cyclone chamber through the exhaust port 34. When the dust collection chamber 4 is full of dust particles, the top cover 5 can be opened to clean the dust collection chamber 4 and the cyclone chamber. Alternatively, the filter element 12 can be disassembled, replaced, or cleaned.
