The specific embodiment

For clearer understanding content of the present utility model, this utility model is described in further detail below in conjunction with accompanying drawing.

As everyone knows, the operation principle of anion generator is: utilize high voltage electric field to make air ionization produce (just) ion, and the running voltage that ionic generation needs lies prostrate several ten kilovolts by thousands of.In order to guarantee personal safety, avoid touching high-pressure section, generally all will bear (just) ion generator and place an airtight housing, the anion that its anion generator produced is overflowed by a special window that is provided with.

As shown in Figure 1, the present invention comprises casing, movement circuit, emission of ions 11, bleeder resistance 14, casing is made up of housing 13 and conductive protection grid 12, conductive protection grid 12 is connected with certain potentials, conductive protection grid 12 is connected on a certain current potential of the negative terminal of power supply or anode movement circuit and is made up of power supply circuits and oscillation step-up circuit by bleeder resistance 14, power supply circuits divide interchange (civil power) power supply circuits and DC power-supply circuit (comprising aneroid battery) again, and can change mutually by switch 4; Multistage voltage-multiplying circuit 9 is connected by protective resistance 10 and emission of ions 11, and emission of ions 11 is made up of the spray point or the hairbrush that discharges.

As shown in Figure 2, circuit connecting mode and operation principle are as follows:

When efficiently, when easily the diffusion anion generator is applied to civil power (220V) voltage, L (phase line) holds resistance R 1 blood pressure lowering in blood pressure lowering current-limiting circuit 1, and by current limiting capacitance C1, resistance R 2 is connected with D1 anode D2 negative terminal in the rectification circuit 2, civil power N (zero line) end is connected with D3 anode D4 negative terminal, the D1 of rectification circuit, the D3 negative terminal is connected with filter capacitor C2 anode in the filter circuit 3, the D2 of rectification circuit, the anode of D4 is connected with the negative terminal of filter capacitor C2, export corresponding DC voltage by the anode of filter capacitor C2 and add power supply circuits 5 to permutator 4 (aneroid battery), through the peripheral circuit C3 of IC and the pin of L1 adding IC, after IC (DC/DC) conversion, the dc voltage stability of output remains unchanged on a certain magnitude of voltage substantially, and its function is equivalent to source of stable pressure.Capacitor C 4, C5 are the desired filter capacitors of IC peripheral circuit, IC output galvanic current is pressed and is outputed to permutator 4, can make anion generator work in line voltage by permutator 4, be applied to household appliances such as air-conditioning, frost, also but on-line operation is in DC voltage (aneroid battery), is made into the portable negative ion generator and is applied in vehicle-mounted, the individual health care product.Booster circuit 8 is the single piece type piezoelectric ceramic transformer; permutator 4 is added on oscillating circuit 7 with DC voltage; the multiple tube oscillating circuit that the biasing circuit that DC voltage is formed by R4, R5 forms for Q1, Q2 provides bias voltage; be connected with protection diode D6 on the multiple tube; boost output and provide feedback signal to form self-excitation to the base stage of multiple tube Q1 by distribution capacity coupling of sheet type piezoelectric ceramic transformator PT, the mechanical resonant frequency of its frequency of oscillation and sheet type piezoelectric ceramic transformator is approaching.Take into account vibration, amplify, provide the triple duties of energy to provide the input energy by the multiple tube that Q1, Q2 form to sheet type piezoelectric ceramic transformator PT.

The sheet type piezoelectric ceramic transformator obtains exciting power from oscillation circuit, the sheet type piezoelectric ceramic transformator produces about N output voltage doubly that boosts and is transferred to multistage voltage-multiplying circuit 9, the outfan of sheet type piezoelectric ceramic transformator links to each other with diode D7, D8 in the cockcroft-walton voltage multiplier circuit 9, the cockcroft-walton voltage multiplier circuit that constitutes by elements such as D7, C7, D8----D9, C8, D10, according to the requirement of output voltage height, the progression of increase and decrease cockcroft-walton voltage multiplier circuit makes output voltage reach the above DC voltage of thousands of volts.The cockcroft-walton voltage multiplier circuit links to each other with protective resistance 10 by diode D11, and protective resistance 10 and anion emission 11 is connected.Protective resistance 10 11 o'clock has the certain protection effect there being the people to touch emission of ions.Emission of ions 11 can be made of metal discharge pin or conductive carbon cellulose fiber brush.High pressure on the emission of ions head and air generation corona discharge produce anion.Conductive protection grid 12 is a part with fishnet shape aperture (are mesh is very big and grid is very thin), places the dead ahead of emission of ions head.Conductive protection grid 12 is connected on a certain current potential of the negative terminal of power supply or anode by bleeder resistance 14; bleeder resistance 14 should have necessary insulation voltage and a certain size resistance value, and the size of its insulation voltage and resistance value adapts with negative (just) high-voltage value that ion generator had.

Because the protection grid is relative and the emission of ions head is a positive potential, so anion is had sucking action, can accelerate the effusion speed of anion.Anion after the acceleration is by the shell of the mesh effusion instrument of protection grid.In the effusion process of anion; the protection grid has played the effect that helps anion to overflow on the one hand; also hinder simultaneously and adsorbed the sub-fraction anion; the accumulation of anion can make the current potential of grill-protected lattice become negative gradually, and current potential becomes negative and arrives to a certain degree; the acceleration of protection grid will diminish gradually; up to disappearance, after the further change of the current potential of protection grid is negative, also can play the effusion that hinders anion.The effect of bleeder resistance 14 is exactly the electronegative ion of protected grid absorption of in time releasing, and makes its acceleration of protection grid performance.Adjust the resistance of bleeder resistance, can also adjust the height of protection grid current potential.
