The negative ion technology is to utilize negative oxygen ions formed by discharging at a low pressure to capture bacterial and viral particles in the air to form a negatively charged Legionella particle which is collided with other objects to generate instant discharging so as to realize the sterilization function, but the inactivation rate and the inactivation efficiency are low. The ultraviolet technology comprises different light source technologies such as mercury lamp tubes, LED lamp beads and the like, and has the advantages of short service life, higher cost and larger damage to equipment materials. The plasma technology is composed of a tungsten wire emitter and a dust accumulation electrode of a metal plate, and an arc discharge formed by a voltage difference between the tungsten wire and the metal plate is used for forming a plasma air state, but the service life of the plasma technology is long, and ozone and nitrogen oxides with the concentration exceeding the standard can be generated.

The emitter tips 41 are uniformly distributed in a dense state, and are uniformly distributed in the longitudinal direction and the transverse direction, and the whole emitter tips are in a low-wind resistance mode.
In particular, the vertical distance between the tip of the emitter tip 41 and the end of the positive electrode plate 20 near the emitter tip 41 is 8-12cm. Preferably, through trial and error, the distance is set to 85mm, so that the positive electrode plate 20 is prevented from reducing the positive voltage corona field kinetic energy caused by too close between the tip of the transmitting needle point 41 and the positive electrode plate 20, even the arc discharge is generated after the transmitting needle point 41 is directly discharged to the electrode plate group, the unsafe hidden danger of arc discharge is caused, and the reduction of the effectiveness of carrying charges due to the influence of the air corona field effect caused by too far away free electrons is avoided, so that the reduction of the actual adsorption collision effect is caused.
So arranged, the emitter needle plate 40 can release a large amount of free electrons into the flowing air in the direction of the positive electrode plate 20 and the return electrode plate 30, so that various particulate particles (including oxygen molecules and the like) in the air can carry a high proportion of free electrons. Colony clusters carrying a large number of free electrons and particles with viruses can be easily impacted or adsorbed by the polar plate under the action of field kinetic energy, and the point discharge effect in a microscopic state can form the damage effect on organic tissues consisting of bacteria and viruses at the moment of touching the polar plate so as to inactivate the bacteria and the viruses.
As shown in fig. 4 to 6, in some embodiments, the number of return electrode plates 30 is set to 25 and the number of positive electrode plates 20 is set to 26. It should be noted that, according to the understanding of the technical solutions of the present application by those skilled in the art, the number of the loop electrode plates 30 and the number of the positive electrode plates 20 in the present application may be adjusted according to needs, and only the consistent number or one difference between the number of the loop electrode plates 30 and the number of the positive electrode plates 20 is required, that is, the number of the loop electrode plates is n, and the number of the positive electrode plates is n+1 or n-1, so as to ensure that the channels of the interaction interval are formed between the loop electrode plates 30 and the positive electrode plates 20.

So arranged, the return electrode plates 30 are positioned at the center between the adjacent positive electrode plates 20 on both sides, thereby forming a driving electric field in which electrons are penetrated relatively at intervals. In addition, the return electrode plate 30 is in turn connected to the negative pole of the output of the adapter 10 to form a continuous electron field counter field. The electron field naturally has a certain driving force to polar microparticles relative to the motion field, and free electrons of the transmitting needle are loaded to various microparticles, so that the microparticles are more easily absorbed by the polar plate and microcosmic touch to form a micro-point discharge effect, thereby achieving the effects of sterilization and virus killing.
Further, the interval between any adjacent two return electrode plates 30 and the positive electrode plate 20 is not more than 5mm. Preferably, through repeated experiments, the distance between the loop electrode plate 30 and the positive electrode plate 20 is set to be 5mm, so that not only can strong adsorption force be generated between the two electrode plates, but also high-energy discharge effect can not be directly formed between the two electrode plates.
As shown in fig. 4 to 6, in some embodiments, the return electrode plate 30 and the positive electrode plate 20 are both aluminum alloy sheets, and the thickness thereof is 0.8mm. The aluminum alloy sheet is formed by drawing a light aluminum alloy serving as a base material by adopting a drawing die, and then the required length is cut according to the required length. The electrode plates adopt the design concept of ultrathin electrode plates, more groups of electrode plates can be combined, so that the equal spacing between the positive electrode plate 20 and the return electrode plate 30 is not more than 5mm, and the weight of a single electrode plate is greatly reduced under the condition. Specifically, the return electrode plate 30 has a length of 300mm and a width of 41mm. The positive electrode plate 20 had a length of 280mm and a width of 61mm.
In addition, the middle position of the loop electrode plate 30 is provided with a central rib column 31 along the length direction thereof, the positive electrode plate 20 is symmetrically provided with two groups of side rib columns 21 along the length direction thereof, the central rib column 31 and the side rib columns 21 can increase the overall hardness and rigidity of the electrode plate, and the diameters of the central rib column and the side rib columns are 1.2mm. In particular, the spacing between the two sets of side ribs 21 is the same as the width of the return electrode plate 30, so that when the air duct passes through the pole piece set channels, three super strong adsorption field areas are formed in the channels between the two different pole pieces, and the areas are important areas for triple sterilization and virus killing.

The combined boost circuit 55 is coupled to the second boost converter circuit 54 and includes a number of diodes and capacitors connected in series-parallel.
The circuit of the ion module 50 adopts the same frequency modulation mode and push-pull output frequency-increasing mode, then carries out secondary voltage transformation frequency-increasing and voltage-increasing through the step of the capacitor diode, and then carries out double-resistance high-frequency low-current output mode combination, so that the high-voltage direct current output by the ion module 50 can keep a low-current ultrahigh-voltage output situation with higher frequency, the energy consumption of output power can be greatly reduced in the process of limiting the output of lower frequency, the power consumption of a single ion module 50 is controlled to be about 5W, the electric energy consumption is reduced by more than 90% compared with that of a common electrostatic module, meanwhile, the ultrahigh voltage difference can form a good potential difference, and free electrons are relatively easy to release into the air.

The large-resistance resistor is used as the short-circuit resistor 12, so that the input of low-frequency signals can be reduced while high-frequency interference signals are avoided, and excessive energy consumption is avoided. In addition, the reverse discharge electric energy signal plays a role in inhibiting and reducing the energy consumption of the whole circuit.

In addition, the short-circuit resistor 12 with the resistance value not smaller than 5MΩ is connected in parallel to the EMI transconductance capacitor group between the front-stage circuit and the rear-stage circuit, so that the output end of the adapter 10 is added with loop compensation, the output negative electrode of the adapter 10 is used as the grounding end of the loop electrode plate 30, a bleeder loop is formed between the high-voltage high-frequency electricity and the adapter 10, and the practical use safety and stability of the adapter 10 are greatly improved.
