A kind of negative ion air purifier

Abstract

The invention discloses a negative ion air purifier. The negative ion air purifier comprises at least one launching needle row and at least one carbon fiber bundle launching row which are connected with a negative high-voltage pulse excitation power supply, wherein the launching needle row is distributed with a plurality of launching needles in rows through a base plate; the base plate is a printed circuit board; the base plate is arranged in a bottom box; one side of the base plate abuts against the bottom of the bottom box; the launching needles extend out of the outer part of the bottom box through needle holes of the bottom box; the other side of the base plate is provided with a first bus plate; the first bus plate is fixed by jacking through a box cover, so that the first bus plate is electrically connected with the plurality of the launching needles; the launching needles are fixed with the base plate through tail parts by riveting; a first detecting line made up of a copper clad layer is further formed on the base plate; and launching heads of the carbon fiber bundle launching row are detachably connected to a launching base through screw-thread fit. The negative ion air purifier has the beneficial effects: the launching heads and the launching needles of an air purifier negative ion generator are convenient to replace, electrical connection is reliable, and the detecting line is not required to be independently arranged. The negative ion air purifier is simple in structure, convenient to dismount, high in production efficiency and high in reliability.

Description

technical field [0001] The patent of the present invention relates to an air purifier, in particular to a negative ion air purifier. 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 carbon fiber bundle is inserted into t...
