Novel plateau nuclear biochemical protection electric air supply canister and application thereof

Abstract

The invention discloses a novel plateau nuclear biochemical protection electric air supply canister and application thereof, the novel plateau nuclear biochemical protection electric air supply canister comprises a canister body, and is characterized in that an electric air supply device is arranged in the canister body, wherein the electric air supply device comprises an upper cover, a shell, a lower cover, a motor, fan blades, an air cavity, a check ring, a power supply, a control circuit board and a switch which are connected in sequence. The canister is filter type respiratory protection equipment formed by adding a small-sized electric air supply device on the basis of a layer-mounted canister. The canister has the outstanding characteristics that the air supply device forcibly supplies air to the mask, the air flow is stable, the inspiration resistance of the mask can be greatly reduced, the lung pressure is reduced, the air inflow is improved, the personnel burden is reduced, and the physiological comfort is improved. In addition, certain positive pressure is formed in the mask through forced air supply, and the protection capacity of the mask can be further improved. And meanwhile, in low-temperature, high-temperature and high-humidity environments, a fogging phenomenon of the lens is reduced or eliminated, and the structure is favorably kept clear.

Description

technical field [0001] The invention relates to the technical field of nuclear, biological and chemical single personnel respiratory protection, in particular to a new electric air-supply poison canister for plateau nuclear, biological and chemical protection and its application. Background technique [0002] Gas mask is a kind of respiratory protective equipment, which is used to protect personnel's respiratory organs, eyes and head and face skin from direct damage of poisons, bacteria and radioactive dust. According to different protection principles, it can be divided into two categories: filter type and isolation type. The filter gas mask is to filter the contaminated air into clean air for personnel to breathe. [0003] Existing novel mask is a kind of novelty headband type mask, is made up of canister, mask, mask bag and annex. The research team learned during the investigation of various units that units stationed in plateau areas generally reported varying degrees ...
