The emitter tips 41 are distributed in a uniform and dense state, and are uniformly arranged in the longitudinal direction and the transverse direction, and the whole emitter tips are in a low wind resistance state.
Specifically, 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 8-12 cm. Preferably, through repeated tests, the distance is set to 85mm, so that the situation that the positive electrode plate 20 reduces the kinetic energy of the positive voltage corona field due to too close distance between the tip of the emitter tip 41 and the positive electrode plate 20, even arc discharge is generated after the emitter tip 41 directly discharges to the electrode plate group, and the potential safety hazard of arc discharge is caused is avoided, and the situation that the effectiveness of carrying charges is reduced due to the influence of the air corona field effect on free electrons and the reduction of an actual adsorption collision effect are caused due to too far distance between the tip of the emitter tip 41 and the positive electrode plate 20 can also be avoided.
With such an arrangement, the emitter pin plate 40 can release a large amount of free electrons to the flowing air in the direction of the positive electrode plate 20 and the return electrode plate 30, so that various particles (including oxygen molecules, etc.) in the air can carry a high proportion of the free electrons. Colony groups carrying a large amount of free electrons and particles with viruses can easily be impacted by the action force of field kinetic energy to collide with or be adsorbed by the polar plate, and point discharge effect under a microscopic state can be formed at the moment of touching the polar plate to damage organic tissues consisting of bacteria and viruses so as to inactivate the bacteria and the viruses.
As shown in fig. 4 to 6, in some embodiments, the number of the return electrode plates 30 is set to 25, and the number of the 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 can be adjusted according to the needs, and it is only necessary to ensure that the number of the loop electrode plates 30 is the same as or different from that of the positive electrode plates 20 by one, 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 alternate channels are formed between the loop electrode plates 30 and the positive electrode plates 20.
The loop electrode plate 30 and the positive electrode plate 20 are arranged at equal intervals, and the perpendicular bisector of the loop electrode plate 30 and the perpendicular bisector of the positive electrode plate 20 are superposed, so that the positive electrode plate 20 and the loop electrode plate 30 are in a grid structure at equal intervals, and the central axes of the electrode plates are in the same plane, so that the loop electrode plate 30 is in an internal field return state in the ventilation duct, namely, an internal discharge field effect is formed in an electric field. With this arrangement, the circuit electrode plate 30 is located at the center between the positive electrode plates 20 on the two adjacent sides, so as to form a driving electric field for the electrons to penetrate through the space. In addition, the return electrode plate 30 is connected to the negative pole of the output of the adapter 10, forming a continuous field of relative motion of the electron field. The electron field has certain driving force to polar microparticles naturally relative to the motion field, and free electrons of the emission needle are loaded to various microparticles, so that the microparticles are more easily adsorbed by the polar plate and are microscopically touched to form a micro-point discharge effect, and the sterilization and virus killing effects are achieved.
In addition, the distance between any two adjacent circuit electrode plates 30 and the positive electrode plate 20 is not more than 5 mm. Preferably, through repeated tests, the distance between the loop electrode plate 30 and the positive electrode plate 20 is set to be 5mm, so that strong adsorption force can be generated between the two electrode plates, and a 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 circuit electrode plate 30 and the positive electrode plate 20 are aluminum alloy sheets each having a thickness of 0.8 mm. The aluminum alloy sheet is formed by drawing a light aluminum alloy serving as a base material through 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, and the combination of more groups of electrode plates can be designed, so that the equal distance between the anode electrode plate 20 and the loop 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 41 mm. The positive electrode plate 20 had a length of 280mm and a width of 61 mm.
In addition, the middle position of the circuit 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 31 and the side rib columns are both 1.2 mm. Particularly, the distance between two sets of side ribs 21 is the same as the width of the return circuit electrode plate 30, so that when the air duct passes through the channels of the pole piece sets, three super-strong adsorption field areas can be formed in the channels between two different pole pieces, and the three super-strong adsorption field areas are important areas for triple sterilization and virus killing.
As shown in fig. 7 to 9, in some embodiments, the ion module 50 is provided with a positive and negative high voltage output circuit to control the voltage difference output by the positive and negative output terminals of the ion module 50 to be 25-30 KV.

The high-frequency current-limiting resistors comprise a resistor R7, a resistor R8, a resistor R9 and a resistor R10.
Specifically, three input terminals of the electronic ballast control chip 51 are coupled to the frequency modulation resistor and the frequency modulation capacitor, respectively, so that two output terminals of the electronic ballast control chip 51 push-pull output high-frequency current. An input pin 5 of the electronic ballast control chip 51 is coupled to the frequency modulation resistor R3, an input pin 6 of the electronic ballast control chip 51 is coupled to the frequency modulation capacitor C2, and an input pin 7 of the electronic ballast control chip 51 is coupled to the frequency modulation capacitor C4.

The large-resistance resistor as the short-circuit resistor 12 can avoid passing high-frequency interference signals and reduce the input of low-frequency signals, and does not consume too much energy. In addition, the reverse leakage electric energy signal plays a role in restraining and reducing the energy consumption of the whole circuit.
In the conventional design of the adapter 10, the short-circuit resistor 12RCY does not exist, which causes the electrostatic aggregation process of forming a high-frequency reactance for each component in the rear-stage circuit, and the uncertain electrostatic discharge effect will generate strong discharge breakdown surge and other phenomena at a certain critical point in the adapter 10 circuit, and will cause the possibility of the component of each function in the circuit being damaged by flash or show that the peak noise electromagnetic wave of many uncertain factors can appear on the EMI index. After the short-circuit resistor 12 is added, the loop charge of the high-frequency high-voltage is continuously discharged, but the functions of other low-frequency components are not influenced, and the frequency doubling signal of the electromagnetic induction is discharged at the same time.
In addition, the preceding stage circuit is provided with a combined structure of a rectifying capacitor and a filter inductor, and the direct current conversion process of the rectifier bridge can be relatively stable.
