Embodiment 2

[0015] Existing electrostatic air purifiers do not use distributed capacitor isolators, and the high-voltage generator is directly connected to the electrostatic field, and the particulate matter enters the electric current of the instantaneous discharge of the electrostatic field. The voltage generated by the high-voltage generator is the capacitor composed of the two poles of the electrostatic field, then the charged amount of the capacitor, the equivalent capacitance of the electrostatic field of the electrostatic air purifier is 10, and the total stored charge. Then the particles enter the electric field for an instantaneous discharge time. Since there is no distributed capacitor isolator, the charge on the capacitor will be concentrated at one point and released, and the instantaneous discharge current.

[0016] After the distributed capacitance isolator of the present invention is added to the air purifier, due to the effect of the high-voltage silicon stack, the charge o...

Abstract

The invention relates to a distributed capacitance isolator of an electrostatic adsorption device of an air purifier. The isolator comprises a box body, a PCB (Printed circuit board), a control circuit, a pouring sealant and a plurality of pin terminals. The distributed capacitance isolator has the beneficial effects that in capacitive circuits connected in parallel, a resistor and a high-voltage silicon rectifier stacks are connected in series in each capacitive circuit, so that electrical charges stored at the other capacitors do not be concentrated so as to be discharged at a place in which a capacitor discharges due to short circuit, and therefore the distributed capacitance isolator plays a role in isolating and discharging; the discharge energy is decreased greatly, when particles enter into an electrical field and positive and negative pole pieces are short-circuited, by virtue of decreasing the discharge energetic, an electric spark is weakened, noises and electromagnetic radiation are decreased during sparking, so that the generation of ozone is decreased.

Description

technical field [0001] The invention relates to a distributed capacitance isolator for an electrostatic adsorption device of an air purifier, in particular to a distributed capacitance isolator for an electrostatic adsorption device for an air purifier in the field of indoor civil electrostatic air purifiers. Background technique [0002] At present, there are more and more air purifiers with electrostatic adsorption devices on the market, but most of them simply connect the high-voltage generator directly to the electrostatic field. All charges will be superimposed to this point and released, producing harsh sparking sound, and at the same time producing strong electromagnetic radiation and higher concentration of ozone. Strong electromagnetic radiation will cause common-mode interference and differential-mode interference to the microelectronic circuit of the air purifier, which will affect the normal function and use of the air purifier in severe cases; it will also inter...
