High pressure components and air cleaners

Abstract

The invention provides a high voltage component and an air purifier. The high voltage component provided by the invention includes a tungsten filament, a tungsten filament mounting rack and a cover plate, wherein the tungsten filament mounting rack is provided with a tungsten filament fixing end; a tungsten filament is fixed at the tungsten filament fixing end and is covered by a cover plate; the high voltage component includes a first insulation pad; the first insulation pad is covered on the side, facing to the tungsten filament mounting rack, of the cover plate. According to the invention, as the first insulation pad is covered on the side, facing to the tungsten filament mounting rack, of the cover plate, compared with the prior art, the insulation of tungsten filament and the outside is changed from the insulation of one single cover plate into insulation of the cover plate and the first insulation pad, as a result, the insulation degree of the high voltage component and the outside is increased, electrion is effectively avoided or weakened, and the purification performance is rather stable.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a high-voltage component and an air cleaner. Background technique [0002] In the prior art, the tungsten wire part of the air purifier usually installs the tungsten wire with strong electricity on the tungsten wire mounting frame, and then covers the two ends of the tungsten wire mounting frame (the fixed end of the tungsten wire) with a cover plate, and the tungsten wire The wire mounting frame and the cover plate fix the tungsten wire inside the tungsten wire part, so that the tungsten wire is isolated from other parts, so as to achieve the effect of strong electric shielding. [0003] Since the materials used for injection molded parts such as tungsten wire cover plate are generally strong electric shielding materials, when there is no dust near the tungsten wire assembly and the installation groove, the tungsten wire will not discharge to the installation groove; when the tun...

AI Technical Summary

Problems solved by technology

[0003] Since the materials used for injection molded parts such as tungsten wire cover plate are generally strong electric shielding materials, when there is no dust near the tungsten wire assembly and the installation slot, the tungsten wire will not discharge to the installation slot; When there is a lot of dust, there is a tip near the tungsten wire, and the insulation strength of the injection molded parts such as the cover plate is insufficient, which will cause the tungsten wire to discharge the dust on the wall of the installation groove

[0004] In addition, since the tungsten wire mounting frame and the cover plate are injection molded parts with a certain strength, it is difficult to design the two ends to be completely sealed in structure, which cannot be isolated from the outside world, and dust is easy to escape from between the tungsten wire mounting frame and the cover plate. The gap enters and sticks to the inner surface of the tungsten wire mounting frame and the cover plate. When the dust reaches a certain level, the tungsten wire discharges on the inner surface.
