Electric air supply and negative oxygen-containing gas high-cleanliness filter

Abstract

The invention belongs to the field of breathing gas filtering, and is characterized in that air inhaled by a human body is fed into an inhaled air high-cleanliness low-resistance filtering module by a fan to be filtered into high-cleanliness gas, and then the high-cleanliness gas is converged with negative oxygen ions and is fed into a breathing system protective cover to be inhaled by the human body; gas exhaled by a human body is filtered by the exhaled gas cleaning and filtering module, and clean gas is discharged into a public space. A bag type filtering technology, a multi-connection parallel technology and a space separation technology are adopted, a high-capacity battery is adopted for supplying power, a fan is adopted for supplying air, and a negative oxygen ion generator is adopted for generating negative ions, so that the requirements of people on resistance-free electric air supply and high-cleanliness air with negative oxygen ions in respiratory system protection are met; the air purifier is mainly used for personal virus prevention, flu prevention, haze prevention, industrial and mining dust prevention, household fire control, formaldehyde removal and the like, and can also be used for daily protection of hospital doctors, high-cleaning treatment of air exhaled by infectious disease patients and the like.

Description

technical field [0001] The invention relates to the technical field of respiratory gas filtration, uses an electric air supply method to filter the gas inhaled and exhaled by a human body through a special filter module with high cleanliness, and solves the problems of personal respiratory system protection and social infectious disease prevention and control. Background technique [0002] At present, the commonly known technology is to make masks into SMS and SMMMS with melt-blown non-woven materials, such as N95 masks, which can filter ≥ 0.3 micron particles, bacteria and some viruses, and the material filtration efficiency can be greater than 95%. After the outer aerosols and droplets are lost, only the virus monomers are left attached to the mask. If the number of viruses enriched in the outer layer of the mask is large, it is difficult to avoid small-sized viruses that will not wear out as people continue to breathe repeatedly. Enter the lungs through a larger barrier n...

AI Technical Summary

Problems solved by technology

The first defect is that the respiratory system cannot be well sealed and protected, and the air leakage rate is high, even if it is worn correctly, the air leakage rate is as high as 8%.

The second defect is that the filtration efficiency is not high enough to achieve high-clean filtration, and the resistance is large. Even if the materials of many masks have a filtration efficiency of less than 90%, it will be difficult to breathe after wearing them. People are unwilling to wear them for a long time, and children The mask resistance meeting will cause irreversible damage to children's lungs. According to the filtration tests of children's masks from several manufacturers in the market, the material filtration rate is not high, and they have not provided the necessary protection.

The third defect is that the mask is opaque, not small, and covers most of the face, which is unsightly and stuffy. People are unwilling to wear it for a long time. Many people in the United States even refuse to wear a mask

In addition to the fact that the theoretical filtering effect of the material itself is not high and clean, and because of the serious air leakage rate, the actual comprehensive filtering effect of the existing masks is not good.

In addition, the medical masks and medical surgical masks in the prior art have to be discarded after every 4 hours of wearing due to the large electrostatic loss, and the filtration efficiency is seriously reduced. However, people rarely replace them with new masks after wearing them for 4 hours. The filtration efficiency of the masks worn at the time is seriously insufficient, and the risk of being infected by viruses is very high

[0003] Currently known filters are bulky and are mainly used for indoor filtration and are not suitable for carrying around with human breathing

In addition, currently known filters have limited filtration efficiency, and can only perform clean filtration on the air, but cannot perform high-clean filtration on the air.

Especially for the filters in the known field, the high sealing between the filter material, the container and the pipeline is difficult to be guaranteed, and the risk of virus leakage is high.
