Description

Highly dense adjustable negative ion generating device

Technical field the utility model is a kind of negative high voltage that utilizes, and forms negative electric field, thus ionization surrounding air, the negative ion generating device of generation anion.Have anion density height, scalable, corona free discharge, noiselessness, do not produce characteristics such as ozone.This negative ion generating device can be widely used in fields such as body-care, disease physiotherapy, agricultural production, domestic birds and animals raising, air cleaning.

The negative ion generating device that occurs on the present market of background technology mainly is to produce anion by high-voltage corona discharge.The shortcoming of this device is when producing anion, will supervene a certain amount of ozone and noise, and ozone with high concentration is harmful to human body.And this negative ion generating device also must have a discharge space of isolating with human body, otherwise, when human body will produce electric shock during near electrode.Therefore, the general volume of this negative ion generating device is bigger, can not press close to human body, thereby has limited its application.

Summary of the invention is the deficiency that overcomes existing negative ion generating device, the utility model provides a novel negative ion generating means, both had anion density height, adjustable advantage, the characteristic that also have the corona free electric discharge phenomena simultaneously, do not produce ozone, electrode can directly contact with human body.

The technical scheme in the invention for solving the technical problem is: with 220 volts of alternating currents is power supply, end at power supply, current-limiting resistance R1 connects with four anti-phase diode in series, shunt capacitance C2 between diode D1 and diode D2, shunt capacitance C3 between diode D2 and diode D3, shunt capacitance C4 between diode D3 and diode D4, at diode D1, the interface place of diode D2 and capacitor C 3, connect an end of capacitor C 1, the other end of the other end and power supply links, constitute voltage-doubler rectifier A, with voltage regulator B, current-limiting resistance R2 and electrode C connect in turn.

After the energising, around electrode, form the negative high voltage electric field, thereby ionized air forms anion.Voltage difference, ionizing power are just different, thereby the density of the negative aeroion that produces is just different.By adjusting voltage, reach the purpose of control anion density.

The beneficial effects of the utility model are: obtaining high density, in the time of the scalable anion, corona free electric discharge phenomena, noiselessness, do not producing ozone, also do not having electric shock (discharge) sensation when contacting with human body, and safe and reliable.

Appended drawings is circuit theory diagrams of the present utility model.A is a voltage-doubler rectifier among the figure, and B is a voltage regulator, and 1,2,3,4 is four binding posts of voltage regulator, and C is an electrode, and R1, R2 are current-limiting resistance, and C1, C2, C3, C4 are capacitor, and D1, D2, D3, D4 are diode.

Embodiment as shown in drawings, voltage-doubler rectifier A is connected by four leads with voltage regulator B, constitutes voltage control system, electrode C connects by the insulated conductor flexibility with B.When the positive half cycle input of alternating current R1, diode D1～D4 is reverse not conducting of connection, and power supply will be by R1 → C2 → C4 → D4 → C3 → C1 loop respectively to capacitor C2, C4, C3, C1 charging; When alternating current negative half period input R1, diode D1～D4 reverse-conducting, capacitor C1～C4 discharge is superimposed upon the voltage that stores respectively on the corresponding circuit simultaneously, and voltage is doubled step by step.If this moment, the binding post of B was thrown in the time of 1, the alternating current negative half period passes through D1 through R1, C1 discharge simultaneously, to be transported to 1 point after discharge voltage and the voltage stack by D1, be transferred to electrode C through R2 again, thereby form the negative voltage that approaches the twice supply voltage, i.e. V1=-2V (V is a supply voltage) at electrode C.In like manner, when B throws to 2 the time, D1, D2 conducting, C1, C2 discharge, V2=-3V; When B throws to 3 the time, D1, D2, D3 conducting, C1, C2, C3 discharge, V3=-4V; When B throws to 4 the time, D1, D2, D3, D4 conducting, C1, C2, C3, C4 discharge, V4=-5V.D1=D2=D3=D4=1N4007 among the figure; C1=C2=C3=C4=0.1uF.B is that a hilted broadsword four is thrown band switch.R1＝150KΩ；R2＝10MΩ。C adopts 60 order copper mesh to make, and adopts soft insulating material environmental sealing.The electric pole short circuit electric current only is 0.1mA, so safety, power saving.

Use the basic principle that this device anion takes place,, place in the common seat cushion the mesh electrode insulated enclosure, can be made into the negative ion health seat cushion, when human body is sitting on the pad, can forms highdensity negative aeroion at the human body surrounding space, thereby play the health-care physical therapy effect.In like manner also can be made into negative ion health mattress etc.Electrode is made sheet or needle-like, put into water, ionizable water is made anion water.Can be made into anion water generator or anion water tumbler etc. with this principle.This device is installed on all kinds of body-building apparatus, can in certain limit around the body-building apparatus, forms high density anion space, make the people in motion, suck a large amount of negative aeroions, improve body-building effect the human body beneficial.This device also can be made into air purifier, can significantly improve space anion density, improves air quality.
