Embodiment 1

[0016] Such as figure 1 As shown, a breathing purifier includes: an air inlet 1, a medium-efficiency filter 2 installed behind the air inlet 1, and a fan 3 installed behind the medium-effect filter 2 to form a preliminary air filtration and purification section. The purified air enters the air inlet pipe 4, flows through the inner channel 6 of the heat exchanger, and simultaneously absorbs the heat of the gas in the outer channel 7 of the heat exchanger to preheat and raise the temperature. The preheated air is sent to the two-stage heater 9, and is heated to After the temperature is above 120 degrees Celsius, it is sent to the far end of the high-temperature gas storage box 11 through the air supply pipe 10, and the high-temperature gas stays in the high-temperature gas storage box 11 for a period of time, and the bacteria and viruses are fully killed by the high temperature, and then flow through the air outlet 12. Enter the heat exchanger outer channel 7, the air cooled in ...

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...
