Breathing purifier

Abstract

The invention discloses a breathing purifier. A medium efficiency filter is arranged in front of a fan, a heat exchanger is arranged behind the fan, the heat exchanger is provided with an inner channel and an outer channel, two sections of heaters are arranged between the inner channel and an air supply pipe, a high-temperature air storage box is arranged behind the two sections of heaters, and outlet air of the high-temperature air storage box passes through the outer channel of the heat exchanger, and then is sent to a breathing mask through an air outlet pipe and a secondary cooling device. According to the breathing purifier, the technology of treating viruses and bacteria by high temperature is adopted, retention is generated by utilizing the breathing interval time of a human body and the air pressure change of the breathing mask, the high-temperature retention time is prolonged by increasing the stroke when air flows through a high-temperature air storage box, air subjected to medium-efficiency particle filtering is subjected to high-temperature treatment for a certain time, viruses and bacteria are killed through high temperature, and the breathing resistance problem is solved through active air supply.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a breathing purifier capable of killing viruses and bacteria. Background technique [0002] Existing respiratory purifiers usually remove harmful substances such as particles in the air by filtering. This kind of air treatment method based on filtration has defects. Due to the presence of a large number of particles, bacteria and viruses in the air, the performance of the filter material will decrease after a period of use and needs to be replaced. The mask generally only needs to be replaced in a few hours. Bacteria and viruses have a limited filtration rate and have a certain respiratory resistance. The electronic mask is equipped with a fan to assist, but increasing the air flow to the small air inlet and multiple filter materials accelerates the accumulation of particles, and the filter material must be replaced frequently. The effective use time of the canister is also shor...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects of limited killing effect on bacteria and viruses, non-reusable materials and respiratory resistance of purifiers in the breathing purification process in the prior art, the present invention provides a technology for treating viruses and bacteria at high temperature, using human breathing interval time Combined with the air pressure change of the breathing mask and the air flow through the high-temperature air storage tank, the stroke is increased to prolong the high-temperature residence time. The air after the medium-efficiency filter particles is subjected to high-temperature treatment for a certain period of time, and viruses and bacteria are sterilized by high temperature. Kill, and carry out active air supply to solve the problem of breathing resistance
