Fig. 1 is a schematic partial cross-sectional view of a cleaning assembly according to an embodiment of the present invention, as shown in fig. 1.
The air cleaning device comprises a housing 10, a suction driving source 20 and a cleaning assembly 30.
Wherein, the shell is provided with an air inlet 11 and an air outlet 12.

The first potential module 31 and the second potential module 33 have a potential difference therebetween to form an electric field region passing through the filtering module 32, and the air passing through the electric field region is sterilized by the high-voltage electric field between the first potential module 31 and the second potential module 33 while the particles and the volatile harmful gas in the air are filtered by the filtering module 32. When bacteria or viruses pass through a high-voltage electric field, the surfaces of the bacteria and the viruses are charged with a large amount of positive electricity or negative electricity, and after the electricity is charged, the bacteria and the viruses generate neutralization discharge to generate a large amount of energy to kill the bacteria or the viruses. Meanwhile, a high-voltage electric field can generate trace ozone in the process of ionizing the ambient air, and the strong oxidizing property of the ozone can kill bacteria and viruses. The filtering module 32 is located in the high-voltage electric field, bacteria and viruses retained on the filtering module 32 can be removed through the high-voltage electric field, and secondary pollution of air or mildew of a filtering membrane group are avoided, so that the purifying work efficiency is improved. The air purifier provided by the embodiment of the invention has the killing rate of more than 99% on most common bacteria (such as staphylococcus albus, staphylococcus aureus and the like) and viruses (such as influenza A H1N1, influenza virus H3N2 and the like).
In an embodiment, the housing 10 is provided with an operation key, a display screen, an indicator light, etc. through which the inhalation driving source 20 in the housing 10 can be controlled, and a user can know the operation status of the air purification apparatus according to the display screen and the indicator light. The air inlet 11 comprises a plurality of through holes, and a filter screen is arranged on one leeward side of each through hole. The structure of the air outlet 12 is the same as that of the air inlet 11, and details are not repeated here. The suction driving source 20 includes at least one fan, and sucks air outside the housing 10 from the air inlet 11 through the fan, and then purifies the sucked air through the first potential module 31, the filter module 32, and the second potential module 33 in sequence. The filtration module 32 includes, but is not limited to, HEPA.
Further, in an implementation embodiment, one of the first potential module 31 and the second potential module 33 is a first high voltage module, and the other is a first zero potential module. The first high-voltage module comprises a high-voltage generator, high voltage generated by the high-voltage generator can eliminate various bacteria, and a potential difference is formed between the high-voltage generator and the first zero potential module to generate a high-voltage electric field to ionize air.
Furthermore, in order to enable bacteria or viruses passing through the high-voltage electric field to be charged with positive electricity or negative electricity, in an embodiment of the present invention, the first high-voltage module is a positive high-voltage module or a negative high-voltage module. When bacteria or viruses pass through a high-voltage electric field, the surfaces of the bacteria and the viruses are charged with a large amount of positive electricity or negative electricity, and after the electricity is charged, the bacteria and the viruses generate neutralization discharge to generate a large amount of energy to kill the bacteria or the viruses.
Further, in an implementation manner of the present invention, referring to fig. 2, when the first potential module 31 is the first high voltage module, and the second potential module 33 is the first zero potential module, a second zero potential module 34 is further disposed on the upstream side of the first potential module 31 in the air flow. The first high-voltage module and the second zero-potential module 34 have a potential difference therebetween to form a first high-voltage electric field capable of sterilizing, the second high-voltage electric field is formed between the first high-voltage module and the first zero-potential module, double sterilization is performed by the first high-voltage electric field and the second high-voltage electric field, and triple purification is performed by the filter module 32 in cooperation with air. Meanwhile, the second high-voltage electric field can sterilize the filtering module 32. Meanwhile, a high-voltage electric field can generate trace ozone in the process of ionizing the ambient air, and the strong oxidizing property of the ozone can kill bacteria and viruses.

The shielding layer 35 mainly prevents the first high voltage module from being too far away from the first zero potential module, which results in too low concentration of generated ions. Further, a shielding layer 35 may be disposed on the surface of the filter module. The first zero potential module is arranged on the surface of the filtering module.

The positive and negative pressures between the second high-voltage module 36 and the first high-voltage module are opposite, ions generated by the positive and negative voltages are more than those generated by the high-voltage module and a zero potential, and the sterilization effect is better. However, the cost of arranging the high-voltage modules with opposite polarities is high. In fact, to achieve the same effect, the voltage of the high voltage module needs to be doubled when the high voltage module is set in the zero potential mode. For example, doubling positive pressure, such as 4000V to 0V, does not differ significantly from the number of ions generated by 2000V positive and 2000V negative pressure. For cost saving, the positive and negative pressures between the second high voltage module 36 and the first high voltage module may be the same, for example, the second high voltage module 36 includes a high voltage generator, and the high voltage generated by the high voltage generator can destroy various bacteria.

Furthermore, a shielding layer 35 for keeping the distance within a predetermined range is disposed between the first high voltage module and the second zero voltage module 34.

22. The air purification apparatus of any one of claims 1, 2, 3, and 16 to 21, wherein when the outermost module of the purification assembly is a high voltage module, the outermost layer of the purification assembly is a safe distance from the inner wall of the housing.
23. An air purification method, comprising:
applying corresponding voltage to one or both of the first potential module and the second potential module to generate a potential difference between the first potential module and the second potential module so as to form an electric field area passing through the filtering module;
the suction driving source is controlled to work so as to suck air to be purified through the air inlet, and the sucked air is purified by the filtering module and then is discharged from the air outlet.
24. The method of claim 23, wherein energizing one or both of the first potential module and the second potential module with a respective voltage comprises:
one of the first potential module and the second potential module is electrified with positive high voltage or negative high voltage, and the other one is kept at zero potential; or
And one of the first potential module and the second potential module is electrified with positive high-voltage, and the other one is electrified with negative high-voltage.
