Description

Miniature anion generator

Technical field

The utility model relates to a kind of generation and is introduced into ion unit in the atmosphere, especially a kind of volume is little, high temperature resistant, low price, supporting easy to use, or can use separately, can be mainly used in various light fixtures such as electricity-saving lamp, ceiling light, and the miniature anion generator of various devices such as hair dryer, utensil.

Background technology

Air negative ion generator has been widely used in various occasions, to improving indoor air environments such as car, ship, public place of entertainment, office space, factory floor, hospital, room, ensures healthy certain effect of having played.The version of existing air negative ion generator is of a great variety.Notification number provides a kind of little power consumption anion generator for the patent application of CN 2124517U, be made of negative high-voltage generator and the negative high-voltage electrode and the zero electrode grid that are located at the ion chamber, negative high-voltage generator is little power consumption high-frequency DC-AC-DC converter that integrated circuit and discrete circuit are formed; High-field electrode adopts the point-like negative high-voltage electrode, and zero potential electrode adopts linear zero potential utmost point grid, and the two forms the semi open model electrostatic field.Notification number is the miniature air anion generator that the utility model patent of CN2169935Y discloses a kind of direct current supply, it comprises negative high voltage generation circuit, in negative high voltage generation circuit, collector electrode-emitter energy storage capacitor in parallel and a damper diode of the switching transistor of the flyback conversion booster circuit of separate excitation vibration, utilize the pectination negative peak high pressure that obtains to equal 8～10 times of supply voltages that discharges and recharges between the elementary winding of energy storage capacitor and step-up transformer, by damper diode the magnetic field energy in the elementary winding of step-up transformer is sent back to power supply with the form of electric current simultaneously.Application number provides a kind of anion generator that is applicable to medical treatment and environmental protection for the patent application of CN 86207208U, is made up of anodal orifice plate, negative pole orifice plate, needle point discharge and air purifier.Air purifier is arranged at the air inlet place of negative ion generating device, makes that negative ion generating device is dustless to be amassed, and has brought into play the effect of anion effectively.Corona pole plate in the air purifier is to be made of through being wrapped on the insulation board corona wire.Increased corona wire length and promptly increased electric field strength, made ionic weight obtain increasing.But the structure of existing air negative ion generator is more complicated all usually, and resistance to elevated temperatures is poor, and volume is big, the price height.

Summary of the invention

The utility model aim to provide a kind of simple in structure, resistance to elevated temperatures good, volume is little, the miniature anion generator of low price.

The utility model is provided with

Housing;

The controllable silicon oscillator signal produces circuit, its input external power supply:

Step-up transformer, its elementary oscillator signal output that connects controllable silicon oscillator signal generation circuit;

High-voltage rectifier, it imports the secondary of termination step-up transformer;

Discharge electrode is connected to the output of high-voltage rectifier.

Housing can adopt open column shape body or square hollow body etc., preferred cylinder.Produce the current circuit of to limit between circuit and the power supply at the controllable silicon oscillator signal, be advisable with current-limiting resistance.Power supply can adopt mains supply.High-voltage rectifier can be selected high voltage silicon stack for use.Discharge electrode can be selected carbon fiber discharge electrode or spray point for use, preferred carbon fiber discharge electrode.

If adopt the 220V civil power after current limliting unidirectional control silicon controlled break-make to produce oscillator signal, through boost, rectification can obtain several kilovolts high pressure approximately, and utilize carbon fiber to atmospherical discharges, and produce a large amount of negative aeroions and drop ozone gas after the ionization, be released in the atmosphere.The structural design compactness of obvious whole device, price is very low, and resistance to elevated temperatures is good, can be with combinations such as itself and various device, utensil, devices, or monomer uses, various electric equipments, dustbins etc. such as for example various light fixtures such as electricity-saving lamp, ceiling light, and hair dryer form the product with multiple function.
