an air purifier

Abstract

An air purifier, which includes a housing, a high-voltage electrostatic adsorption unit and a front ionization unit, characterized in that the front ionization unit structure is that two serrated metal sheets are arranged on the left and right sides of the front position of the air duct , and a positive DC high voltage is connected to the serrated metal sheet, and the positive DC high voltage output of the high voltage generator is connected to the two serrated metal sheets, thereby arranging an electrostatic ionization field; or the front ionization unit structure is in front of the air duct The carbon brush is set at the position, followed by a steel ring, the positive DC high voltage output of the high-voltage generator is connected to the carbon brush, and the steel ring is grounded, thereby forming an arc-shaped electrostatic ionization field between the carbon brush and the steel ring. The high-voltage generator described above is a high-voltage generator with a voltage output of KV level and a current output of uA level, which can control the amount of ozone released to an extremely low, almost negligible range, so that no deozone module is required. The structure is more reasonable and practical.

Description

technical field [0001] The invention relates to an air purifier. Background technique [0002] At present, there are generally two types of electrostatic dust collectors on the market. One is that the front negative (or positive) metal wire 1a (electrode wire) is the discharge electrode, and the rear is composed of dust-collecting metal plates of different geometric shapes 3.1 , 3.2 is the dust collection module. The dust collection module is generally arranged at intervals of dust collection metal sheets of two sizes, in which positive and negative DC high voltages are connected to form an electrostatic field for capturing particles; the negative (or positive) metal wire is applied with a kilovolt level The above DC high voltage uses the corona effect to negatively charge the air dust particles, and then uses the Coulomb force to trap the charged particles on the dust collection device to achieve the purpose of dust removal and air purification. An ozone processing unit is ...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is complex, there are many parts, the process requirements are high, and the cost of the whole machine is high;

[0004] 2. It is very easy to generate ozone, which is easy to exceed the standard, affects human health, and forms secondary pollution;

[0005] 3. In order to make the ozone emission lower than GB, it is generally necessary to add an ozone-absorbing module to prevent the ozone concentration from exceeding the standard. The module is generally expensive, and its service life is not permanent. In addition, due to manufacturing process or storage problems, it is easy to suddenly ineffective, difficult to control;

[0006] 4. For purifiers of the same model size, it is difficult to compare with traditional HEPA filter purifiers when testing CADR (the measure of the purifier's clean air effect in the American AHAM laboratory)
