[0041] The utility model will be further described in detail below in combination with examples, so that those skilled in the art can implement according to the description.

[0042] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0043] Example 1

[0044] A dust-gas separation device with a rotatable cyclone cone, comprising:

[0045] A cyclone cup 1 is provided with an air inlet 11 and an air outlet 12, and the inside of the cyclone cup 1 is hollow to form a cyclone chamber 14, and the cyclone chamber 14 and the air inlet 11 are connected through a helical air inlet channel 13;

[0046] A cyclone cone assembly 2 comprises a support 21 fixedly connected inside the cyclone chamber 14 and a cyclone cone 22 rotatably covered on the support 21;

[0047] and a dust collecting cup 3, which is hollow in the inside to form a dust collecting chamber 31, and is vertically communicated with the cyclone chamber 14;

[0048] The air entering from the air inlet 11 forms a cyclone after passing through the spiral air inlet channel 13 and enters the cyclone chamber 14, so that the cyclone cone 22 rotates relative to the support 21.

[0049] In the embodiment, the cyclone cone assembly 2 further comprises a filter cotton 23 detachably arranged in the support 21, a bearing 24 for rotatably connecting the cyclone cone 22 and the support 21, and a sealing ring 25 connected between the cyclone cone 22 and the support 21. The filter cotton 23 is used for filtering tiny dust particles.

[0050] In the embodiment, the support 21 comprises a ring-shaped base 211, a plurality of support rods 212 evenly and spacedly connected to the ring-shaped base 211 in a ring shape, a support plate 213 connected to the support rods 212, and a mounting frame 214 arranged on the support plate 213, wherein the mounting frame 214 is formed with a mounting opening 215, and the bearing 24 is fitted in the mounting opening 215.

[0051] In the embodiment, the cyclone cone 22 is hollow in the inside and comprises a cylindrical body 221 and a tapered tip 222 formed by the front end of the cylindrical body 221 being shrunk; a plurality of rib plates 223 protruding from the wall surface of the cylindrical body 221 are arranged on the wall surface of the cylindrical body 221 in an inclined direction; a plurality of through holes 224 are densely arranged on the wall surface of the cylindrical body 221 at positions avoiding the rib plates 223; and the outer surface of the tapered tip 222 is inwardly recessed to form a plurality of crescent-shaped grooves 225 arranged in a spiral shape.

[0052] The rib plates 223 can improve the structural strength of the cyclone cone 22, and on the other hand, when subjected to the action of the cyclone airflow, the rib plates 223 can serve as the main force receiving part to receive the thrust of the airflow and force the cyclone cone 22 to rotate. Meanwhile, when subjected to the action of the cyclone airflow, the crescent-shaped grooves 225 can also generate a driving force to promote the rotation of the cyclone cone 22.

[0053] In this embodiment, the bottom of the cylindrical body 221 is open, and the cyclone cone 22 is fitted on the support 21 through the cylindrical body 221. The inside of the conical tip 222 is connected to a centrally protruding mounting column 226, which includes a large column segment 2261 and a small column segment 2262 arranged in sequence from top to bottom, and a step surface 2263 is formed between the large column segment 2261 and the small column segment 2262. The small column segment 2262 is fitted into the inner ring of the bearing 24 and is fixedly connected to the inner ring of the bearing 24 through the screw 26, and the step surface 2263 is in abutment with the inner ring of the bearing 24. Thus, when the cyclone cone 22 is subjected to an external force, the cyclone cone 22 and the inner ring of the bearing 24 can rotate relative to the mounting frame 214 of the support 21; the cyclone cone 22 and the annular base 211 of the support 21 are in flexible contact through the sealing ring 25, which can maintain good sealing during relative rotation and allow the airflow to pass through the through hole 224 of the cyclone cone 22 into the interior of the cyclone cone 22.

[0054] In this embodiment, the inside of the conical tip 222 is also connected to an annular retaining ring 227 that is spaced apart and arranged around the mounting frame 214, which can prevent dust from entering the bearing 24 arranged in the mounting frame 214 and causing the bearing 24 to jam.

[0055] In this embodiment, the inner side wall of the cyclone chamber 14 near the one end of the air inlet 11 is centrally protruding and forms a mounting seat 141, which is spaced apart from the inner wall of the cyclone chamber 14 to form a spiral air inlet passage 13 between the outer periphery of the mounting seat 141 and the inner wall of the cyclone chamber 14, and the spiral air inlet passage 13 is provided with a wind guide plate 131 that spirally rises around the mounting seat 141.

[0056] The mounting seat 141 is hollow inside and forms an air outlet cavity 142 that connects the space below the filter cotton 23 and the air suction port 12.

[0057] In this embodiment, the dust collecting cup 3 includes a cup cover 32 fixedly connected to the bottom of the cyclone cup 1 and a cup barrel 33 detachably connected to the bottom of the cup cover 32, the cup cover 32 is provided with an ash inlet 34, and the cup cover 32 and the cup barrel 33 surround to form a dust collecting chamber 31, which is in vertical communication with the cyclone chamber 14 through the ash inlet 34.

[0058] In this embodiment, the left and right sides of the cyclone cup 1 are respectively detachably connected to a left cover plate 15 and a right cover plate 16.

[0059] In this embodiment, the cyclone cone assembly 2 and the mounting seat 141 of the cyclone cup 1 are detachable, which facilitates the cleaning of the cyclone cone assembly 2.

[0060] The dust and gas separation device of this embodiment can be applied in cleaning electric appliances such as mite removers or vacuum cleaners. Taking the application in a mite remover as an example, the main working principle of this embodiment is as follows:

[0061] During the cleaning operation, the power source of the dust cleaner generates a suction negative pressure in the interior of the cyclone chamber 14 through the air suction port 12. The dirty air flow sucked by the suction nozzle of the dust cleaner enters the cyclone chamber 14 through the air inlet 11. The dirty air flow with dust and other particulate matters is forced to follow a spiral upward path around the spiral air inlet channel 13 under the guidance of the air deflector 131, so as to form a cyclone of the dirty air flow in the spiral air inlet channel 13. The cyclone air flow forces the cyclone cone 22 to rotate at a high speed relative to the support 21, so that the hair and other filamentary objects in the dirty air fall onto the surface of the cyclone cone 22 and are thrown off without being easily entangled on the cyclone cone 22, thereby avoiding the entanglement of the hair and lint on the cyclone cone 22, reducing the frequency of cleaning the cyclone cone assembly 2, and improving the dust-air separation efficiency. The dust particles with large size or mass are thrown into the dust collection chamber 31 which is vertically communicated with the cyclone chamber 14 through the dust inlet 34 (the dust collection chamber 31 is vertically communicated with the cyclone chamber 14, which is beneficial to enhancing the cyclone effect in the dust cyclone cup 1), the dust particles with small size are filtered by the filter cotton 23 and are retained in the cyclone chamber 14, the retained small dust particles are thrown into the dust collection chamber 31 together with the subsequent cyclone of the dirty air flow, the clean air flow filtered by the filter is drawn out of the cyclone chamber 14 through the air suction port 12, and when the dust particles in the dust collection chamber 31 are full, the cup barrel 33 can be taken off from the cup cover 32 for cleaning. After long-term use, the left cover plate 15 and the right cover plate 16 can be taken off, and then the cyclone cone assembly 2 can be taken off for cleaning the interior of the cyclone cup 1 and the cyclone cone assembly 2.
