Examples

As shown in fig. 1 to 3, a pole piece structure 100 for generating a sterilizing and virus-killing electric field is disposed at an air outlet end of an emitter needle plate 40, and includes a plurality of positive electrode plates 20 disposed side by side at equal intervals, a plurality of return electrode plates 30 disposed side by side at equal intervals, and ribs disposed on the positive electrode plates 20 and the return electrode plates 30, respectively. The loop electrode plates 30 are respectively and correspondingly arranged between two adjacent positive electrode plates 20, so that an electronic propulsion field is formed between the loop electrode plates 30 and the positive electrode plates 20. The plurality of loop electrode plates 30 are each connected to the low voltage terminal, and the plurality of positive electrode plates 20 are each connected to the high voltage terminal to generate an electric field therebetween for deflecting the charged microparticles.

So set up, the emission faller 40 makes oxygen molecule in the air and microparticle carry free electron, when the high-voltage electric field that forms between positive electrode plate 20 and return circuit electrode plate 30, produces microcosmic point after bacterial colony and virus and the polar plate contact and bump the lightning effect, makes its inner structure destroyed in the twinkling of an eye to by quick deactivation.

As shown in fig. 1-2, in some embodiments, the low voltage terminal is a negative output terminal of the adaptor 10 connected to an external power source, and a positive output terminal of the adaptor 10 is connected to the ion module 50. The plurality of positive electrode plates 20 are all connected with the positive output end of the ion module 50, and the emitter needle plate 40 is connected with the negative output end of the ion module 50.

The adapter 10, the ion module 50, the transmitting needle plate 40, the positive electrode plate 20 and the loop electrode plate 30 form a high-frequency high-voltage potential field kinetic energy sterilization and virus killing device. When the high-frequency high-voltage potential field kinetic energy sterilization and virus killing device is actually assembled, the two ends of the plurality of loop electrode plates 30 and the two ends of the plurality of positive electrode plates 20 are respectively fixed on the installation strips, the installation strips are fixed in the square box body, the emission needle plate 40 is fixed at the air inlet of the square box body, and the ion module 50 and the adapter 10 are fixed on the outer peripheral wall of the square box body. Particularly, the shell of the square box body and the ventilation channel in the square box body are made of insulator materials, so that the consumption of redundant energy consumption is avoided, and the power of the whole module is ensured not to exceed 10W. The whole structure is simple, energy-saving and efficient, the safety performance is good, and the service life is long.

In the subsequent test process of the high-frequency high-voltage potential field kinetic energy sterilization and virus killing device manufactured by the technology, the PM2.5 concentration is 0mg/cm in the measured overfire particle state of the equipment under a certain wind speed (such as less than or equal to 1m/s, which is equivalent to the flow of 200m 3/h) ³ ) I.e., toward a pure, clean microparticle state.

As shown in fig. 2 to 3, in some embodiments, the firing pin plate 40 includes a mounting plate, and a plurality of firing pin tips 41 uniformly disposed on a side of the mounting plate adjacent to the positive electrode plate 20. It is noted that the emitter tip 41 may be a stainless steel needle, a tungsten needle, a gold-plated needle, a tungsten filament emitter, a carbon fiber emitter, or the like.

The mounting plate and the positive electrode plate 20 are perpendicular to each other, and include a plurality of mounting bars that equidistant set up side by side and the connecting strip of locating the mounting bar both ends separately. A row of launching needlepoints 41 which are arranged at equal intervals are arranged on any one mounting strip. 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.

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 8-12 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.

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 solution 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 requirement, and it is only necessary to ensure that the number of the loop electrode plates 30 is the same as or different from the number 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.

In addition, the return electrode plate 30 is connected to the negative pole of the output terminal of the adapter 10, forming a continuous field of 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, a central rib column 31 is arranged at the middle position of the loop electrode plate 30 along the length direction of the loop electrode plate, two groups of side rib columns 21 are symmetrically arranged on the positive electrode plate 20 along the length direction of the positive electrode plate, 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 both 1.2 mm. In particular, the distance between two sets of side rib-shaped columns is the same as the width of the loop electrode plate 30, so that when the air duct passes through the channel of the pole piece group, three super-strong adsorption field areas can be formed in the channel 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. Preferably, in actual use, the voltage difference is set to 28KV, so that the positive output terminal of the ion module 50 outputs +14KV high voltage, and the negative output terminal of the ion module 50 outputs-14 KV high voltage.

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 tuning resistor R3, an input pin 6 of the electronic ballast control chip 51 is coupled to the tuning capacitor C2, and an input pin 7 of the electronic ballast control chip 51 is coupled to the tuning capacitor C4.

Two output terminals of the electronic ballast control chip 51 are respectively and correspondingly connected to two triodes to form a push-pull frequency-increasing circuit 52. The output pin 11 of the electronic ballast control chip 51 is coupled to the transistor Q1, and the output pin 13 of the electronic ballast control chip 51 is coupled to the transistor Q2.

The secondary boost converter circuit includes a first boost converter circuit 53 coupled to the two transistors, and a second boost converter circuit 54 coupled to the first boost converter circuit 53. The first boost converter circuit 53 is formed by a transformer T1, and the second boost converter circuit 54 is formed by a transformer T2.

The combined boost circuit 55 is coupled to the second boost converter circuit 54 and comprises a plurality of diodes and capacitors connected in series and parallel.

So set up, the same frequency modulation mode is adopted to the circuit of ion module 50 and the mode combination that push-pull output is raised frequency again through secondary vary voltage is raised frequency and is stepped up and pass through two resistance high frequency low current output again, can make the high voltage direct current of ion module 50 output keep the higher low current superhigh pressure output situation of a frequency, the in-process that has restricted the output of lower frequency will greatly reduced output power's energy consumption, control single ion module 50's power consumption about 5W, reduce the electric energy consumption more than 90% in ordinary static module, super high voltage difference will form a fine potential difference simultaneously, free electron releases in the middle of the air relatively easily again.

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 may cause the electrostatic aggregation process of forming a high-frequency reactance for each component in the post-stage circuit, and the uncertain electrostatic discharge effect may generate a strong discharge breakdown surge at a certain critical point in the adapter 10 circuit, and may cause the possibility of the component of each function in the circuit being flashed or represent the spike noise electromagnetic wave with many uncertain factors on the EMI index, etc. 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.

So set up, through being connected return circuit electrode board 30 with the negative pole output of adapter 10 to form three-way line between messenger ion module 50, return circuit electrode board 30, the adapter 10 and connect, obviously improved local electromagnetic effect's interference, solved simultaneously a lot of because the result that the actual life of ion module 50 that the improper setting of return circuit point arouses reduces. In addition, a short-circuit resistor 12 with a resistance value not less than 5M Ω is connected in parallel to the EMI transconductance capacitor bank between the front-stage circuit and the rear-stage circuit, so that loop compensation is added to the output terminal of the adapter 10, and the output negative electrode of the adapter 10 is used as the ground terminal of the loop electrode plate 30, so that a leakage loop is formed between the high-voltage high-frequency power and the adapter 10, and the safety and the stability of the practical use of the adapter 10 are greatly improved.
