Embodiment Construction

[0012] In case of emergencies such as firefighting and disaster relief, gas explosions, etc., protective personnel should wear complete isolated oxygen respirators according to the wearing requirements. First open the mouthpiece cover 2 at the top of the exhalation hose 18 and the suction hose 4, connect the breathing mask 1, and then put on the breathing mask 1 quickly after blowing a few breaths on the breathing mask 1. At the same time, the power switch 9 is turned on, and the exhaled carbon dioxide directly enters the oxygen-generating medicine tank 14 through the exhalation hose 18 and reacts with the oxygen-generating medicine in the oxygen-generating medicine tank 14 to generate oxygen and store it in the air storage bag 13. The breathing gas of the airbag 13 is cooled down by the cooling module 7, then inhaled into the lungs of the wearer through the suction hose 4, and completes a breathing cycle, and then reciprocates successively to continuously provide the fresh...

Abstract

The invention relates to a respirator, and in particular relates to an isolated-type oxygen respirator. The isolated-type oxygen respirator comprises a lower shell 17, an upper shell 21, an oxygen generation tank 14 and an air storage pocket 13, wherein a return switch press plate 15 is arranged on the upper cover plate of the oxygen generation tank 14, a breathing mask 1 is connected above the return switch press plate 15, and the air storage pocket 13 is connected below the return switch press plate 15, the breathing mask 1 is communicated with the oxygen generation tank 14 and the air storage pocket 13 by an exhalation valve 19 and an inhalation valve 3, and a exhalation hose 18 is additionally arranged between the breathing mask and the oxygen generation tank; the breathing mask 1 is communicated with a cooling module 7 and the air storage pocket 13 by the exhalation valve 19 and the inhalation valve 3, and an inspiration hose 4 is additionally arranged between the breathing mask 1 is communicated with the cooling module 7; a lithium ion battery pack 11 is used for providing a power supply for the running of the cooling module 7, and a continuous cooling effect can be realized by carrying a backup power supply. The isolated-type oxygen respirator has the main characteristics of being convenient to maintain and preserve, capable of realizing continuous cooling, good in cooling effect, small in size, and safe and reliable.

Description

technical field [0001] The invention relates to a respirator, in particular to an isolated oxygen respirator. Background technique [0002] In the high-temperature disaster relief environment at the fire scene, the chemical oxygen respirator has the problem of excessively high suction temperature, and it must be cooled before the user can breathe normally. Blue ice is the most common cooling method in respirators, and its cooling duration is limited by the volume of the ice box. When the blue ice in the ice box undergoes a complete phase change, it loses its cooling capacity; the process of replacing the ice box is complicated, and it is not easy to carry and store a spare ice box at the scene of a fire, and it may melt in advance. For this reason, develop a kind of novel isolated oxygen respirator to solve the above problems. Contents of the invention [0003] The object of the present invention is aimed at the complex environment and characteristics of the fire scene, ...
