In the description of the present invention, "a plurality" means two or more.
A fan 1 according to an embodiment of the present invention is described below with reference to the drawings, and the fan 1 may be a circulation fan.
As shown in fig. 1 to 9, a fan 1 according to an embodiment of the present invention includes a housing 100, a blower (not shown), and an electrostatic precipitator assembly 300.
The housing 100 is provided with an air inlet 110, an air outlet 120 and an air duct 130 communicating the air inlet 110 with the air outlet 120, the fan is disposed on the housing 100 and located in the air duct 130, the electrostatic dust collection assembly 300 includes a plurality of electrode units 310, the plurality of electrode units 310 include at least one high potential unit 311 and at least one low potential unit 312, each electrode unit 310 includes a conductive portion and an insulating portion 330, the conductive portion includes an electric field generator 321 and a conductive end 322, and the insulating portion 330 at least covers a part of the electric field generator 321. The high potential units 311 and the low potential units 312 are alternately arranged in a ring, and a dust removing air duct 340 is formed between adjacent high potential units 311 and low potential units 312.
It is understood that the electric field generating body 321 refers to a portion of the conductive portion for generating an electric field. The conductive end 322 refers to a portion of the conductive portion for achieving electrical conduction.
According to the fan 1 of the embodiment of the present invention, the insulating part 330 covers at least a portion of the electric field generating body 321, so that the adjacent electric field generating bodies 321 are separated by a layer of insulating material, on one hand, corona discharge between the adjacent electrode units 310 is avoided, ozone generation is reduced, the risk of electric shock accidents is reduced, and the safety of use is greatly improved, on the other hand, each electrode unit 310 can be formed into a whole by adopting a covering method, which is beneficial to simplifying assembly, and each electrode unit 310 is formed into an independent whole, so that independent replacement of each electrode unit 310 can be facilitated no matter in production and use, for example, if a certain electrode unit 310 is found to have a defect in production, it can be replaced independently, and it is not necessary to process the whole of a plurality of electrode units 310 or electrostatic dust removal assemblies 300, thereby indirectly improving the yield of products and saving production cost, during the use process, the single electrode unit 310 can be replaced, so that the maintenance and the repair during the use process are facilitated.
Because a high-voltage electric field can be generated between the adjacent electrode units 310 of the electrostatic dust collection assembly 300, air molecules can be ionized into positive ions and negative ions through the high-voltage electric field, when the negative ions are in contact with bacteria, molds, viruses and the like, the negative ions carry redundant electrons, molecular protein structures in the bacteria, the molds, the viruses and the like can be damaged, structural changes (two polarities of proteins are reversed) or energy transfer can be generated on the bacteria, the molds, the viruses and the like, and therefore microorganisms such as bacteria, viruses and the like can die.

According to some embodiments of the present invention, as shown in fig. 7, the thickness of each electrode unit 310 gradually decreases inward in the radial direction of the electrostatic precipitator assembly 300. Because the electrostatic dust collection assembly 300 is formed into a ring shape, the circumference of the electrostatic dust collection assembly 300 is gradually reduced in the radial inward direction, and therefore the thickness of each electrode unit 310 is also gradually reduced in the radial inward direction of the electrostatic dust collection assembly 300, so that the gap between adjacent electrode units 310 can be ensured to be always the same in the radial direction of the electrostatic dust collection assembly 300, that is, the width of the dust collection air channel 340 is kept consistent in the radial direction of the electrostatic dust collection assembly 300, and further, the electric field intensity between adjacent electrode units 310 is ensured to be the same everywhere, the dust collection and sterilization effects are stable and uniform, and the wind resistance is small.
According to some embodiments of the present invention, as shown in fig. 6, an end face of the electrostatic precipitator assembly 300 is configured with a receiving groove 350, and at least a portion of the fan is located in the receiving groove 350.

Wherein the radial portion 315 forms a bottom wall of the receiving groove 350 and the axial portion 316 forms a peripheral wall of the receiving groove 350. Therefore, the position of the fan and the electrostatic dust collection component 300 is ensured to be compact, the dust collection area of the electrode unit 310 is ensured, and the volume and the dust collection and sterilization effects of the fan 1 are considered.
According to some embodiments of the present invention, as shown in fig. 2, the axis of rotation of the fan coincides with the central axis of the electrostatic precipitator assembly 300. Wherein, the fan can be an axial fan. Thus, the position of the fan and the electrostatic dust collection assembly 300 is more compact, the internal space of the fan 1 is saved, the space utilization rate of the fan 1 is improved, and the fan 1 is miniaturized.
According to some embodiments of the present invention, as shown in fig. 6, the surface of the axial portion 316 facing the fan is gradually inclined toward the fan along the direction toward the radial portion 315, and thus, the cross-sectional area of the receiving groove 350 is gradually reduced toward the direction of the radial portion 315. Because the fan includes motor and flabellum, and the size of flabellum outline is greater than the size of motor outline, consequently, the flabellum can be arranged in axial 316 for the biggest position of the rotation axis's of fan angle, so both can guarantee that the holistic cross-sectional area of flabellum is enough big to increase the airflow of fan 1, can avoid again electrode unit 310 with mutual interference between the fan.
