Negative ion air purification device

Abstract

The invention discloses a negative ion air purification device. The negative ion generation device comprises a negative ion generating device which comprises a first shell and a negative ion emittinghead which is electrically connected to a negative high voltage. The device is characterized in that the first shell comprises a first shell body and a second shell body which are respectively in a hollow pipe shape and allow air to pass through from the two ends; the first shell body is arranged at the periphery of the second shell body at an interval; the negative ion emitting head is arranged on the inner circumferential wall of the first shell body and / or the inner circumferential wall of the second shell body and faces the middle of the first shell body. The anion generating device is arranged to be provided with the tubular shell, and the negative ion emitting head is arranged on the inner circumference of the shell, so that air can vertically pass through the negative ion generatingdevice to take away the high-concentration negative ions and enable micro-particles in the air to be well combined with the negative ions.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a negative ion air purification device. Background technique [0002] At present, the methods for removing particulate matter from the air on the market mainly include filtration and ionization. Among them, the filtration method needs to consume filter materials and has a large wind resistance. Ionization includes high-voltage static electricity and negative ion purification, etc. High-voltage static electricity refers to applying negative high voltage to the tungsten wire and generating discharge with the grounded plate, so that the particles in the passing air are negatively charged, and then the particles are collected to achieve air purification. Negative ion purification refers to an environment optimization that uses the negative ions produced by itself to purify, remove dust, deodorize, and sterilize the air. Harmful substances in the air. [0003] A traditional negative ...

AI Technical Summary

Problems solved by technology

[0004] In general negative ion purification devices, only one or several negative ion heads are placed in the device, resulting in uneven combination of released negative ions and micro particles in the air, resulting in low purification efficiency; The devices are all collected by HEPA. Since the positive charge of the stationary electrode inside the HEPA will gradually disappear, the ability to collect negatively charged particles will become worse and worse, eventually leading to failure
