Description

A kind of anion generator

The utility model belongs to the device that purifies air.Be that a kind of high voltage electric field ionized air produces the anion generator of anion to purify air.

People's state of mind such as producing nervous, tired, insomnia of in lacking the environment of anion, living, particularly all the more so in air-conditioned room.So anion generator development makes and contains a certain amount of anion in the air after coming out and using, can not only make with fresh airly, make the people feel comfortable, clearheaded; Simultaneously, airborne anion can be with showy aerial dust, bacterial virus, smog is combined into neutral ion and sedimentation has catharsis to air.But existing anion generator is used for family expenses, adopts the 220V electric main through rectification and be depressurized to DC voltage about 30V, produces the oscillating current of a high frequency again through oscillating circuit, negative direct current high voltage of output after multiplication of voltage repeatedly again after boosting.This class anion generator shortcoming is to adopt the power supply of 220V voltage, does not match with industrial equipment; Simultaneously, boost after the step-down and multiplication of voltage, its circuit structure is complicated, and it requires the progression of multiplication of voltage more; In addition, high-frequency oscillating circuits is to communication, all have interference to household electrical appliance.

The purpose of this utility model provides a kind of being used for and the matching used anion generator of central air conditioning group.Also can use separately.Its input 380V AC power also can be imported 220V.By boost, multiplication of voltage, rectification circuit, the negative direct current high voltage of output ten thousand volts, supporting central air-conditioning unit uses, and air is carried out ionization, produces the anion of high concentration, reaches the catharsis to air.

The utility model is realized with following mode: it comprise shell and interior by boost, multiplication of voltage and discharge circuit and power-supply controller of electric form; feature is to have circuit in the shell; constitute the integrated circuit structure by power supply control with short-circuit protection circuit I, power indicating circuit II, the transforming circuit III that boosts, dc high-voltage circuit IV and emitter stage F, and be connected to the resistance R of protection against electric shock at emitter stage F input ₃And IV is connected with dc high-voltage circuit.Power supply control is made up of fuse FV with short-circuit protection circuit I; Power indicating circuit II is made up of signal lamp XD; Boost transforming circuit III by transformer TR, resistance R ₄Form; Dc high-voltage circuit IV is by diode VD ₁VD ₂VD ₃, resistance R ₁R ₂, capacitor C ₁C ₂C ₃Form; Circuit connecting relation is as follows: fuse FV inserts power line, and is connected with transformer TR primary coil, is connected with signal lamp XD on transformer TR secondary coil, is serially connected with resistance R at an end of another secondary coil of transformer TR ₂, capacitor C ₂, end is serially connected with resistance R in addition ₁, capacitor C ₁, capacitor C ₃, diode VD ₃VD ₂An end all be connected capacitor C ₂One end, in addition end respectively with capacitor C ₃Two ends be connected diode VD ₁One termination is gone into resistance R ₂Capacitor C ₂Between point of contact, in addition termination is gone into capacitor C ₁Capacitor C ₃Between point of contact, resistance R ₄One termination is gone into resistance R ₁, capacitor C ₁Between point of contact, in addition termination is gone into transformer TR primary coil, resistance R ₃One termination is gone into capacitor C ₃Diode VD ₃One end point of contact, end is connected with emitter stage F input in addition.

This anion generator simple structure, Nover practical, circuit design is reasonable.The anion emission electrode design becomes open electrode, is negative pole with the spray point needle point of installing in the air-conditioning box, and the absorption utmost point is that the air conditioning box body anticathode has very high positive potential, is equivalent to the positive pole of generator.The negative ion concentration height that produces, 8 * 10 ⁶Individual/cm ³More than.Ozone concentration is low.Be provided with the absorption utmost point and can eliminate airborne dust, smog effectively, and have sterilizing ability.Healthy positive effect arranged for what ensure people.Negative high voltage is directly boosted after the several times by the power-frequency voltage of step-up transformer with input in the circuit design, obtains through voltage tripler rectifier again, compares with other direct booster circuit to have the booster voltage height, and the rectification multiple is few, and circuit working is reliable, the characteristics that power output is big.The utility model and central air conditioning assembly cover.Its power supply is easy with the control of 380 volts of alternating currents and air-conditioning box motor synchronous, and the input of power supply is connected to power supply indicator and short-circuit protection, and is safe and convenient to use.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is a circuit diagram of the present utility model.

With reference to Fig. 1, the utility model and central air conditioning assembly cover, operation principle is as follows: exchange 380V voltage by fuse FV, the primary coil that is added to step-up transformer TR is a primary side, at secondary coil is that secondary end induces two groups of voltages, one group is the power lamp XD voltage that exchanges 6.3V, and another group is that output voltage is the high pressure of thousands of volts In first cycle, when positive half cycle, transformer R ₁End is positive R ₂End is negative, at this moment VD ₁Conducting, electric current is by current-limiting resistance R ₁, R ₂To C ₁Charging, C ₁Be recharged approaching

, and remain unchanged substantially.Work as R ₂End is being for just, R ₁End is for bearing transformer-secondary voltage

With C ₁VD is passed through in last voltage addition ₂To capacitor C ₂Charging makes C ₂Be charged to approaching

When the positive half cycle of second period arrives, transformer R ₁End is being for just, R ₂End is negative, at this moment VD ₁Repeat said process.Simultaneously, because capacitor C ₂Be filled with Voltage, this voltage and transformer-secondary voltage

Addition makes VD ₃Conducting makes C ₃Be charged to

So, on spray point, obtain C ₁, C ₃The voltage sum, approaching Output at dc high-voltage circuit IV is provided with the protection against electric shock resistance R ₃, to guarantee personal security.Whole dc high-voltage circuit IV is by the discharge loop resistance R ₄Making the voltage of exporting on the spray point is that air conditioning box body and object on every side are a direct current negative high-voltage with respect to adsorption plate, produce corona discharge, surrounding air ionization, the cation that produces in ionization process is turned back to negative pole by powerful negative high voltage electric field attracts, and anion is surveyed the repulsion that is subjected to negative electric field, move to positive pole rapidly, thereby drive flowing of surrounding air, form a kind of what is called " ion wind ".Capacitor C in the circuit ₁～C ₃, diode VD ₁～VD ₃Be three voltage multiplying rectifiers, can increase doubly on demand.The Ben Lufei higher-order of oscillation boosts, to communication, the noiseless effect of household electrical appliance.
