Problems solved by technology

[0004] There are indoor air purifier products at home and abroad (such as Daikin, Panasonic, Sharp, etc.), but they are of filter type, which are effective for dust but not for fine dust (PM2.5), and are generally equipped with fans, which cause noise to the environment Pollution
At the same time, there are also products on the market that use the principle of ozone generators to purify the air. Because they are harmful to the human body, the Ministry of Health has banned the promotion of them.

Embodiment 1

[0019] Such as figure 1 , figure 2 As shown, a kind of plasma dust purifier of the present embodiment comprises AC-DC converter 1, EMI filter 2, high-frequency generator 3, voltage doubler circuit 4 and cleaning device 5; Wherein said AC-DC The converter 1 is connected to the EMI filter 2 and the high-frequency generator 3 through a line respectively; the high-frequency generator 3 is connected to the voltage doubler line 4 through a line; the purification device 5 adopts a non-self-sustaining discharge and releases negative ions ; The high-frequency generator 3 uses a 4-12Mhz wide-spectrum alternating electric field generator, which can generate a high-frequency, 10-30KV alternating electric field, and the output current is not greater than 20ua. The purpose of voltage and current control is to ionize fine dust and not generate ozone. The described pressure doubler line 4 is connected to the purification device 5 through the line; the described purification device 5 includ...

Abstract

The invention discloses a plasma micro-dust purifier comprising an AC-DC (Alternating Current-Direct Current) converter, an EMI (Electro-Magnetic Interference) filter, a high-frequency generator, a voltage-multiplying line and a purifying device, wherein the AC-DC converter is respectively connected with the EMI filter and the high-frequency generator through a line; the high-frequency generator is connected with the voltage-multiplying line through a line; the voltage-multiplying line is connected with the purifying device through a line; the high-frequency generator is connected with a control line through a line; and the control line is connected with the lines of the AC-DC converter and the high-frequency generator. The plasma micro-dust purifier disclosed by the invention has the advantages of being free from light, noises and ozone, and capable of enhancing space negative ions through non-self-maintained discharge, can effectively collect and adsorb PM2.5 (Particulate Matter 2.5) micro-dust, reduces the indoor concentration to meet the national standards and improves an indoor environment; and the negative ions are released so as to improve the immunity of a human body.

Description

technical field [0001] The invention relates to a plasma fine dust purifier, which belongs to the field of energy-saving and environment-friendly electronics. Background technique [0002] At present, compound air pollution in my country is gradually on the rise, especially air particulate pollutants, among which PM2.5 has attracted widespread attention. PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. In February 2012, the State Council agreed to release the new...
