Negative ion generation device and filtering device using negative ion generation device

Abstract

The invention discloses a negative ion generation device. The negative ion generation device comprises a negative ion generator and is characterized by further comprising a humidifying device for humidifying the air passing through; the negative ion generator comprises a negative ion ball; and in the flowing route of gas, the humidifying device is positioned at the upstream of the negative ion generator. The invention further discloses a filtering device using the negative ion generation device. A negative ion ball material without pollution and energy consumption is adopted, and negative ionswith the target concentration can be obtained without supplying power to the device, so energy saving and environmental friendliness are achieved, and negative ions for binding with microparticles and beneficial to body health can be provided; and by a humidifier method, local humidity is improved, the negative ion ball can be excited to generate negative ions, and high-concentration negative ions are bound with the microparticles in the air to form particles with large particle size.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a negative ion generating device and a filtering device using the negative ion generating device. Background technique [0002] In recent years, the problem of air pollution in our country has become increasingly prominent, and people are more aware of the impact of air quality on human health and the necessity of air purification. Therefore, at present, air purifier products among environmental protection products are more and more popular among people. The market potential is huge. [0003] Commonly used air purifiers include negative ion air purifiers, ozone air purifiers, ultraviolet air purifiers, photocatalytic air purifiers and plasma air purifiers, as well as various types of combined purifier products. Negative ion active purification technology uses negative ions to combine with micro-particles in the air to form large particles, which are easier to be filtered by the f...

Problems solved by technology

[0005] The existing above-mentioned negative ion generating devices usually release a low concentration of negative ions, and if a higher concentration of negative ions needs to be obtained, the voltage needs to be increased, which puts forward higher requirements for product safety and cost. In the field of purification, HEPA filters are often used to improve purification efficiency, but with the failure of HEPA filters, the purification efficiency gradually weakens
