A kind of negative ion generator provided with emitting needle row

Abstract

The invention discloses a negative ion generator provided with an emitting pin row. The negative ion generator comprises a negative high voltage pulse excitation power supply, wherein the negative high voltage pulse excitation power supply is connected with at least one pin row; the pin row comprises multiple emitting pins arranged in rows through a substrate; the substrate adopts a printed circuit board structure; the substrate is arranged in a bottom box; one side of the substrate props against the bottom of the bottom box; the emitting pins extend out of the bottom box from pin holes in the bottom box; a busbar board is arranged on the other side of the substrate; the busbar board is pressed and fixed by the box cover in a jacking manner, so that the busbar board is in electrical connection with multiple emitting pins; the emitting pins and the substrate are riveted and fixed through the tail parts; a detection line formed by a copper-clad layer is also formed on the substrate; the detection line and the emitting pins are in an insulating state; and inductive charges are formed when the emitting pins emit negative ions. The negative ion generator has the beneficial effects of convenient replacement of the emitting heads of the emitting pin row in the generator, reliable electrical connection, simple structure and good convenience in detaching, high production efficiency, high reliability and high capability of being washed or cleaned singly without needing to set the detection line independently.

Description

technical field [0001] The patent of the present invention relates to an air purifier, in particular to a negative ion generator provided with a row of emitting needles. Background technique [0002] Negative ion air purifier is an environment-optimized appliance that uses its own negative ions to purify, remove dust, deodorize, and sterilize the air. Harmful substances in the air, while traditional air purifiers use a fan to draw air and use a filter to filter dust to purify the air. This is called the passive adsorption filter purification principle, and the filter needs to be replaced regularly, while the negative ion air purifier does not need consumables. The negative ion purifier includes a negative high-voltage pulse excitation power supply and multiple rows of emitting heads arranged in rows. The emitter head mainly has two structural forms: emitter needle and carbon fiber bundle. The carbon fiber bundle is connected to the terminal through the metal head, and the c...
