Embodiment 1

[0037] Embodiment one: the human body respiratory protection method of the present invention, it comprises the steps:

[0038] 1) wear a transparent mask, a breathing bag cavity is formed between the transparent mask and the human face, and a gap is formed between the edge of the transparent mask and the face, and the gap is less than 5mm in the present embodiment;

[0039] 2) Enter the sterilized air into the breathing bag cavity, so that the air pressure inside the breathing bag cavity is higher than the air pressure outside the breathing bag cavity, and the air in the breathing bag cavity flows out from the gap between the edge of the transparent mask and the face. Isolate the air flow, and use the isolated air flow to prevent the air outside the breathing bag cavity from entering the breathing bag cavity.

Embodiment 2

[0040] Embodiment two: the human body respiratory protective device of the present invention, it comprises transparent mask 1 and is used for the headgear 2 that transparent mask is fixed on the head, forms breathing bag cavity between transparent mask and people's face, the air outlet of breathing bag cavity It is the gap formed between the edge of the transparent mask and the face. In this embodiment, the gap between the edge of the transparent mask and the face is less than 5mm.

[0041] The human respiratory protection device also includes a fan 3 and an exhaust pipe 4 connected to the air outlet of the fan, and the exhaust pipe blows air to the cavity of the breathing bag.

[0042] The human respiratory protection device also includes a filter and sterilization device 5 for eliminating bacteria and viruses in the air discharged from the fan.

[0043] The multi-purpose protection device for human body also includes a power supply 6 for supplying power to the fan.

Embodiment 3

[0049] Embodiment three: the present embodiment human respiratory protective device, it comprises transparent mask 1 and is used for the headset 2 that transparent mask is fixed on the head, forms breathing bag cavity between transparent mask and people's face, and the outlet of breathing bag cavity The air port is the gap formed between the edge of the transparent mask and the face. In this embodiment, the gap between the edge of the transparent mask and the face is less than 5mm.

[0050] The human respiratory protection device also includes a fan 3 and an exhaust pipe 4 connected to the air outlet of the fan, and the exhaust pipe blows air to the cavity of the breathing bag.

[0051] The human respiratory protection device also includes an electronic sterilization device 9 for eliminating bacteria and viruses in the air discharged from the fan;

[0052] The multi-purpose protective device for the human body also includes a power supply 6 for supplying power to the fan and ...

Abstract

The invention discloses a human body respiratory protection method and device. The human body respiratory protection method includes the steps that a respiratory bag cavity is formed between a transparent mask a human face, and air which is subjected to sterilization treatment by a filtration and sterilization device or an electronic sterilization device is introduced into the respiratory bag cavity, so that the air pressure in the respiratory bag cavity is higher than the air pressure outside the respiratory bag cavity. The air in the respiratory bag cavity flows out from gaps between the edge of the transparent mask and the face to form isolated air flow, the isolated air flow is used for preventing the air outside the respiratory bag cavity from entering the respiratory bag cavity. According to the human body respiratory protection method and device, the air in the respiratory bag cavity is blown out from the peripheral gaps between the transparent mask and the human face, the outside air can be prevented from entering the respiratory bag cavity, and thus it is ensured that the air that people breathes in is free of viruses and harmful bacteria, and the purpose of preventing cross infection is achieved. And the air flow in the respiratory bag cavity is always flowing, an exhaled dreggy gas can be quickly exhausted, the feeling that the mask hinders breathing and the pressureof wearing the mask on the face and ears do not exist, and the use comfort is good.

Description

technical field [0001] The invention relates to the technical field of respiratory protection, in particular to a method and device for human respiratory protection. Background technique [0002] In the prior art, in a dangerous environment with viruses and bacteria, people usually wear masks for respiratory protection to avoid cross-infection. When wearing a mask, the edge of the mask needs to fit tightly with the face to prevent outside air from directly entering the mask without being filtered by the mask. However, in actual use, it is difficult to make the edge of the mask completely seal and fit the face. Large, the outside unsafe air may still enter from the gap between the mask and the face, thereby causing protective loopholes. In addition, if you wear a mask for a long time, the pressure on the face by the side of the mask and the pressure on the ear or the back of the head by the mask belt will cause obvious wearing discomfort; and when you wear a mask to breathe,...
