Description

Anion air purifier

This utility model relates to the electronic installation that purifies air, particularly the electronics ozonator.

Indoor in the sealing of door, window, or in the automobile of sealing, atmosphere draught-free, air ratio are muddy, and antibacterial is also many, people have designed some devices that purify air for this reason, as clean electric cleaner, electric moistening device, air filtration air-conditioning etc., these devices have certain effect for the dust in the decontamination chamber, smog, but weak point is also arranged; Room air does not circulate, and pathogenic bacteria is grown in dirt that there was dampness in the air easily, and the existing device that purifies air all can not kill pathogens, and therefore further improved necessity arranged.

The purpose of this utility model is to provide a kind of anion air purifier, and it can remove airborne smog, dust, also has the effect of toxic gas such as sterilization, deodorization, removing carbon monoxide.

The purpose of this utility model is achieved in that

A kind of anion air purifier is provided with negative ion generating circuit in its casing; It is characterized in that: this negative ion generating circuit mainly is made up of rectification circuit, power amplification circuit, booster circuit, phase-shift oscillator circuit, spray point;

Rectification circuit is made of diode D1, D2, resistance R 1, and the anode of diode D1, D2 all passes through K switch 1 and is connected with a jack CT1 of power supply;

Power amplification circuit mainly is made of audion VT1, VT2, resistance R 2, capacitor C 2, transformator B; The emitter stage of audion VT1 is connected with the base stage of VT2, and the emitter stage of VT2 is connected with supply hub CT2 through resistance R 2, and the colelctor electrode of VT1 is connected with the negative electrode of diode D1 with the former limit tap of the colelctor electrode of VT2 through transformator B;

Booster circuit is made of transformator B, one end on the former limit of transformator B is connected with the colelctor electrode of audion VT1, VT2, the other end on the former limit of B is connected with the base stage of audion VT1 through capacitor C 2, diode D4, secondary one end of transformator B is connected with spray point X1, and the other end of the secondary of B is connected with capacitor C 3 in the phase-shift oscillator circuit;

Phase-shift oscillator circuit is made of capacitor C 3 to C8 and diode D5 to D16, described diode is connected in twos, and then it is parallel with one another, become 6 row, diode polar orientation in every row is identical, and the polar orientation of the diodes of adjacent two row is to instead, and described capacitor C 3 to C8 is serially connected in respectively between the two row diodes, form bridge oscillator circuit, the outfan of this oscillating circuit is connected with another spray point X2 through resistance R 4, R5.

This utility model has following useful good effect:

1, this utility model utilizes high-voltage corona to produce ozone, ozone is negative aeroion again, it can in close the positive charge that adsorbs on the flue dust in the air, make flue dust become bulky grain rapidly and sedimentation, therefore, can remove the smog of smoking generation or smog, the dust in the removing kitchen.

2, negative aeroion is given and is airborne " vitamin ", and clinical medicine facts have proved: it can promote the human body metabolism, improves immunity, and the disease of respiratory system, blood circulation, nervous system aspect is had the auxilliary curative effect of doing.

3, airborne anion is that ozone is a kind of strong oxidizer, and oxidant all can sterilize, and the sterilizing ability of ozone is stronger; But also deodorization generates harmless carbon dioxide with the reaction of carbon monoxide toxic gas.

4, this utility model is aesthetic in appearance, volume is little, in light weight, working stability is reliable, ion wind is formed by electronic circuit in the machine fully, noiseless.

5, this utility model is applied widely, and it is medium to be widely used in office, room, kitchen, ward, toilet, car.

Now in conjunction with the accompanying drawings this utility model is described in further detail as follows:

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Please refer to Fig. 1, anion air purifier of the present utility model has ventilation mouth 2 on housing 1, so that the air of the indoor muddiness of anion that produces in the machine exchanges.

This negative ion generating circuit mainly is made up of rectification circuit, power amplification circuit, booster circuit, phase-shift oscillator circuit, spray point;

Please refer to Fig. 2, principle of the present utility model is: with 220 volts of civil powers through diode D1, the D2 rectification, give after the current limliting by audion VT1, the multiple tube that VT2 constitutes carries out power amplification, boost by transformator B again, high-tension electricity after boosting is given three grades of bridge-type phase-shift circuits of capacitor C 3 to C8 and diode D5 to D16 formation again, every grade of phase-shift circuit carries out integration by the integrating circuit that electric capacity and diode constitute to the signal of telecommunication of importing, make it that 60 degree phase shifts take place, three grades of common phases are moved 180 degree, thereby satisfy oscillating condition, ten thousand volts of high pressure that vibration produces are through spray point X1, X2 is to atmospherical discharges, making air ionization produce anion is ozone, as seen from the above analysis this utility model is simple in structure, respond well, safe and reliable.
