As indoor air purification becomes more and more important, especially the harm of microorganisms and Volatile Organic Compounds (VOCs) to the environment is more and more emphasized. In the traditional purification technology, ultraviolet disinfection and ozone disinfection are mostly adopted, but the method has a common mould inactivation effect, has certain harmfulness to human bodies, and has poor disinfection and sterilization effects and safety.
Based on the above consideration, through intensive research, a sterilization module 10, an air purification unit and an air purifier are designed, the air purifier comprises an air purification unit, and the air purification unit comprises a sterilization module 10 and a purification module 20. The sterilization module 10 forms a dielectric barrier discharge area, and a plurality of plasmas are generated in the dielectric barrier discharge area for sterilization, so that the sterilization effect is good, and the safety is high during use; the sterilization module 10 and the purification module 20 are used in combination, so that an electrostatic area is formed between the sterilization module 10 and the purification module 20 for dust removal, and the air purification unit has sterilization and dust removal functions, thereby meeting the integrated use requirements of customers.
Referring to fig. 1 and 2, the sterilization module 10 in an embodiment includes a first insulating member 110, a first electrode 120 and a second electrode 130, wherein the first electrode 120 is inserted into the first insulating member 110, and the second electrode 130 is disposed outside the first insulating member 110.

In the sterilization module 10, the first electrode 120 is grounded, and the second electrode 130 is connected to the high-voltage ac power supply 30, so that a potential difference exists between the second electrode 130 and the first electrode 120 and a plurality of plasmas are generated, and the sterilization module can rapidly sterilize and has a good sterilization effect; by providing the first insulating member 110 and sterilizing the same with plasma, the safety in use is high.
Here, the first insulating member 110 is used as a medium, the first electrode 120 is used as a ground electrode, the second electrode 130 exposed in the air is used as a high voltage electrode, the high voltage ac power supply 30 is used to drive discharge to break down the air discharge, and a large amount of plasma in an ionic state is generated and dispersed on the surface of the whole sterilization module 10, so that the sterilization module 10 realizes surface sterilization and simultaneously charges microorganisms and particles in the air.
It should be noted that the sterilization module 10 can be used alone as a sterilization instrument, and can also be used as a component of an air purifier. For example, a case or a holder is additionally provided to the sterilization module 10, and the second electrode 130 is exposed to the air from the case or the holder, thereby forming a portable sterilization apparatus. The portable sterilizer aims at the surface of an object to be sterilized, can realize quick sterilization and is convenient for a user to operate and use; for example, the sterilization module 10 may be installed in the air purifier to provide the air purifier with a sterilization function.
According to some embodiments of the present disclosure, the material of the first insulating member 110 is at least one of epoxy resin, polypropylene, teflon, and polyimide.
Through this setting, above-mentioned material of first insulating part 110 is the polymer insulating material that weight is lighter, can alleviate the whole weight of module 10 that disinfects to adaptation in air purifier or portable appearance that disinfects, enlarge the application scope of module 10 that disinfects.
For example, the material of the first insulating member 110 may be a single material including only one of epoxy resin, polypropylene, teflon, or polyimide; alternatively, the first insulating member 110 may also be a composite material including at least two of epoxy, polypropylene, polytetrafluoroethylene, or polyimide.
According to some embodiments of the present application, referring to fig. 3, the first insulating member 110 has a thickness ranging from 1mm to 5 mm.

Here, the thickness direction is the X direction shown in fig. 3.
In the present embodiment, the first insulating member 110 has a rectangular parallelepiped shape. In other embodiments, the first insulating member 110 may also have a cylindrical shape or other shapes. Here, the shape of the first insulating member 110 is not limited.
According to some embodiments of the present disclosure, referring to fig. 2 and 3, the first electrode 120 is planar, and the area of the first electrode 120 is smaller than the area of the first insulating member 110. Thus, the first electrode 120 can be completely embedded in the first insulating member 110, so that the first electrode 120 can be effectively protected, and the service life of the first electrode 120 can be prolonged.
For example, the area of the first electrode 120 may be 0.8 times or other times of the area of the first insulating member 110, so that the first electrode 120 can be embedded in the first insulating member 110 well and can meet the use requirement of electrical connection.

It is understood that all of the first electrodes 120 are connected to the ground line 40, all of the second electrodes 130 are connected to the high voltage ac power source 30, and all of the third electrodes 210 are connected to the high voltage dc power source 50. An electrostatic region is formed between the third electrode 210 and the first electrode 120 for dust removal; a dielectric barrier discharge region is formed between the second electrode 130 and the first electrode 120, and several plasmas are generated in the dielectric barrier discharge region for sterilization.

For example, the area of the third electrode 210 may be 0.8 times or other times of the area of the first insulating member 110, so that the third electrode 210 can be embedded in the first insulating member 110 well and can meet the requirement of electrical connection.
