The veneering frame body is internally provided with a partition board which is divided into an air suction chamber and an air expiration chamber, the air suction chamber is positioned on the outer side, the air expiration chamber is positioned on the inner side, a through hole is formed in the partition board, a one-way air inlet valve is installed in the through hole, fresh air in the air suction chamber can enter the air expiration chamber through the one-way air inlet valve, and the one-way air outlet valve is positioned in the air expiration chamber.
The working process is as follows: when a wearer inhales, fresh air enters the inhalation chamber from the filter screen and enters the exhalation chamber through the one-way air inlet valve, and after the wearer inhales the fresh air, exhaled carbon dioxide is discharged from the one-way air outlet valve of the exhalation chamber.
The upper part of the veneering frame body is provided with an eye cover which is provided with an eye cover fixing band. The purpose of the eye shield is to prevent the entry of viruses into the eye.
The working process of the invention is as follows:
after the novel respirator is worn, air is sucked into the air suction chamber through the filter screen, fresh air enters the exhalation chamber to be directly sucked in during air suction by utilizing the one-way air inlet valve, and carbon dioxide is directly exhaled from the air outlet pipe during exhalation. The one-way air inlet valve can prevent carbon dioxide from entering the air suction chamber, and the one-way air outlet valve can prevent external air from entering the air breathing chamber.
The invention has the beneficial effects that:
1. the filtering screen is provided with a honeycomb-shaped long channel and uniform pores, the pore size of the pores can be made into 0.2-100 um according to the requirement, and the new coronavirus can be filtered by 100 percent. Also, the mouth, nose and eyes are completely isolated from the outside.
2. The double-layer one-way air outlet valve of the exhalation chamber ensures that the outside air can not be inhaled by people, and avoids the infection of the people with viruses.
3. The principle of virus isolation of the invention is to filter out virus, and the plate-shaped filter screen can be cleaned and sterilized for a plurality of times, so that the filter screen after cleaning and sterilization can be reused, the whole mask can be reused, and the use cost is greatly saved.
