Plasma air purification-sterilization device

Abstract

The invention discloses a plasma air purification-sterilization device. The air purification-sterilization device mainly comprises a shell, a circulating fan, a primary filter, a plasma reactor, a negative-ion generator, a high-efficiency air filtration device and an MCU (Micro Controller Unit). The air purification-sterilization device is also provided with a circuit protection system to guarantee the sable and safe work of the whole device. A waveform pole plate and an electricity discharging metal wire parallel to the waveform pole plate are adopted to serve as a basic reaction unit of the plasma reactor, and the waveform pole plate can disturb the air entering the waveform pole plate to furthest diffuse the air to the periphery of an electrode wire, so that the aim of complete sterilization is achieved. The plasma reactor works under high voltage and can generate high-concentration plasma for high-efficiency sterilization, and a circuit protection module is arranged so as to allow the device to work stably and reliably. The air purification-sterilization device is also provided with a temperature sensor, an air quality sensor, a dust sensor and a human body infrared detection device which are capable of detecting environment conditions in real time and are matched with the MCU, so that the automatic detection and control on air purification and sterilization are achieved.

Description

AI Technical Summary

Problems solved by technology

In addition, the photocatalytic sterilizing filter of the plasma air sterilizing purifier disclosed in this patent uses photochemical media, and the cost is relatively high

The entire device is not equipped with a protection circuit, and the power supply cannot be automatically disconnected in time under conditions such as overhumidity, overheating, high temperature and short circuit, which not only wastes energy, but also makes the service life of the device short
