The driving part 40 is connected to the dynamic filtering part 30, and the driving part 40 can drive the dynamic filtering part 30 to be rotatably arranged, so that the foreign matter entering the ventilation passage from the first end of the dust collecting part 10 with the air flow is ionized by the ionizing part 20, and then guided to the side wall of the dust collecting part 10 along the radial direction of the ventilation passage for collection, and the air flow filtered by the dynamic filtering part 30 is discharged from the dust collecting part 10 from the second end of the dust collecting part 10.

[0047] In this embodiment, a dynamic filter section (which can be a DP wheel) is added, which allows the automatic dust collection electric purification device to be free of cleaning for several years. The automatic dust collection electric purification device using this structure allows users to avoid disassembling live parts, which not only improves the safety of use, but also improves the user experience. By setting a dynamic filter section in the dust collecting section, foreign matter is guided into the dust collecting section through the dynamic filter section in a preset direction. When the automatic dust collection electric purification device needs to be cleaned, it is only necessary to disassemble the dust collecting section for cleaning. This arrangement avoids the situation in which the entire filter device needs to be disassembled when cleaning is required in the prior art, effectively reducing the difficulty of cleaning and improving the user experience.

[0048] like Figure 5 As shown, the dynamic filter section 30 includes a filter body 31 and a middle filter structure. The filter body 31 is an annular structure. The middle filter structure is arranged in the middle of the filter body 31 to form a mesh structure. Among them, the middle filter structure includes filter strips 32. There are multiple filter strips 32, the first ends of multiple filter strips 32 are connected to the middle of the filter body 31, and the second ends of multiple filter strips 32 extend outward along the radial direction of the filter body 31 and are arranged radially. In this embodiment, the filter strips 32 can also be arranged in an arc structure, and the arc structure is bent in the radial plane of the filter body 31 (that is, the plane along the radial direction of the filter body 31 is bent). Such an arrangement enables foreign matter (such as dust and oil stains) in the airflow to be brought to the dust collecting section for collection under the rotation of the filter body 31, thereby improving the filtering efficiency of the automatic dust collecting electric purification device.

[0049] In the present application, the dynamic filter part 30 can also be set as a filter mesh. The dynamic filter part 30 is made of metal.

[0050] like Figure 6 and Figure 7 As shown, the ionization unit 20 includes an ionization unit. The ionization unit includes an ionization body 21 and an ionization tungsten wire 22. The ionization body 21 is connected to the dust collecting unit 10. The ionization tungsten wire 22 is connected to the ionization body 21, and there are multiple ionization tungsten wires 22. This arrangement makes the structure of the ionization unit 20 simple and reliable. Among them, the two ends of the ionization tungsten wire 22 can be connected to the ionization body 21 through a clamping joint 23.

[0051] In order to further improve the ionization effect of the ionization unit 20 and make the air filtered by the automatic dust collection and electric purification device more fresh, a plurality of ionization units can be provided, and the plurality of ionization units are arranged at intervals along the airflow direction. Figure 2 As shown, Figure 2 An embodiment with two ionization units is shown in FIG.

[0052] like Figure 1 and Figure 2 As shown, the dust collecting part 10 includes a first dust collecting box 11 and a second dust collecting box 12. The first dust collecting box 11 is an arc-shaped structure. The second dust collecting box 12 is an arc-shaped structure, and the two ends of the second dust collecting box 12 are detachably connected to the two ends of the first dust collecting box 11, and are surrounded to form an annular accommodating cavity, the dynamic filtering part 30 is located in the annular accommodating cavity, and at least part of the ionization part 20 is located outside the annular accommodating cavity. This arrangement can facilitate the cleaning operation of the integrated part.

[0053] Further, the dust collecting part 10 also includes a dust collecting net 13. The dust collecting net 13 is an annular structure, and the dust collecting net 13 is arranged along the circumference of the first dust collecting box 11 and the second dust collecting box 12. This arrangement allows dust and other foreign matter to be adsorbed on the dust collecting net 13 to achieve the purpose of collecting dust.

[0054] like Figure 2 As shown, the automatic dust collecting electric purification device also includes a first guide portion 50 and a second guide portion 60. The first guide portion 50 is arranged in the annular accommodating chamber and is located on the first side of the dynamic filter portion 30. The first guide portion 50 is used to guide the airflow ionized by the ionization portion 20 to the dynamic filter portion 30 for filtering. The first guide portion 50 is an annular structure, and the cross-section of the first guide portion 50 along the axial direction of the ventilation channel is a trumpet-shaped structure, and the inner diameter of the first guide portion 50 is gradually reduced along the side close to the dynamic filter portion 30. The outer edge of the first guide portion 50 is connected to at least one of the first dust box 11, the second dust box 12 and the dust collection net 13. The second guide portion 60 is arranged in the annular accommodating chamber and is located on the second side of the dynamic filter portion 30. The second guide portion 60 is used to guide the foreign matter thrown out by the dynamic filter portion 30 to the dust collection net 13. The second guide part 60 is an annular structure, and the cross section of the second guide part 60 along the axial direction of the ventilation channel is a trumpet-shaped structure, and the inner diameter of the second guide part 60 is gradually increased along the side away from the dynamic filter part 30, and the outer edge of the second guide part 60 is connected to at least one of the first dust box 11, the second dust box 12 and the dust collection net 13. Such a setting can effectively improve the filtering effect of the automatic dust collection electric purification device. In this embodiment, the two guide parts are both trumpet-shaped structures, so that the outer edge of the first guide part 50 forms an angle of 30 to 45 degrees with the plane where the middle part is located, and the outer edge of the second guide part 60 forms an angle of 30 to 45 degrees with the plane where the middle part is located. Such a setting is to change the direction of the ionized dirt into the dynamic filter part for re-filtration, and the second is to introduce the dirt thrown out of the dynamic filter part into the box body of the dust collection part. The wind after ionization and collection is purified into clean fresh air and goes out from the ventilation duct.

[0055] The output shaft of the driving unit 40 is connected to the dynamic filter unit 30, and a bearing 70 is provided at the end of the output shaft, and a grounding wire 71 is provided on the bearing 70. The driving unit 40 may be a motor, and the bearing 70 may be a high-speed bearing.

The dirt is collected through the intermolecular binding force; the second is to increase the centripetal force through high-speed rotation with the motor, and throw the dirt into the dust collection part around. There is a dust collection net in the dust collection part, which can better adsorb the dirt. The dirt is collected in the dust collection part. The user can open the dust collection part and replace or clean the dust collection net to achieve the effect of dealing with the dirt.
