Cooling device used in respirator

Abstract

The invention provides a cooling device used in a respirator. The cooling device comprises a shell body (1) and an air flow barrel, a sealing cavity is formed between the shell body and the air flow barrel and used for accommodating cooling agent, and the inner wall and the outer wall of the air flow barrel are respectively provided with heat exchange sheets. High temperature oxygen in the respirator inters into the air flow barrel, blocked by a guide flow blocking plate of the heat exchange sheets inside the air flow barrel, and guided to guide flow holes; accordingly heat conduction performance is enhanced, heat of high temperature air is quickly transmitted to the outside of the air flow barrel and then performed with fusing heat absorption through the cooling agent to efficiently lower temperature, temperature of the high temperature air is brought out, and further temperature of the high temperature air is quickly dropped to below 35 DEG C to be provided for human bodies to breathe. The cooling device used in the respirator effectively solves the cooling problem of rescue and working respirator; overcomes the shortcomings that existing chemical oxygen generation respirators are not provided with cooling devices, can only be applied to self-rescue, and cannot be used for working; expands application range of rescue and working respirators, enables respirator users to be more comfortable and smoother in breathing, and ensures safety of the users.

Description

technical field [0001] The invention relates to the field of respiratory protectors, in particular to a cooling device in the respirator. [0002] Background technique [0003] Rescue and working respirators are used to enter wells or protect personnel in underground mines or in special environments. the fire , gas It is a portable respiratory protective device to prevent the human body from inhaling harmful gas poisoning or hypoxia suffocation during accidents such as , coal dust explosion, etc. Its main purpose is to wear it for users to avoid danger from poisoning or suffocation when various accidents occur; it is suitable for marine ships, underground railways, harmful gas storage warehouses, entertainment venues, large shopping malls and high-rise residential buildings and other places. In order to meet the requirements of escape and rescue in special environments, many countries in the world have increased the research on various respirators, and gradually develope...

AI Technical Summary

Problems solved by technology

In many environments, due to overheating of the ambient temperature, or a large amount of heat generated in the process of producing oxygen (chemical oxygen respirator), the wearer's inhaled gas is overheated and the breathing comfort is not high

[0004] At present, the existing chemical oxygen respirators on the market are not equipped with cooling and cooling devices, and the problem of oxygen production and heat release through chemical reactions has not been solved, thus affecting the further application development and marketing of chemical oxygen respirators; and compressed oxygen The respirator only has a simple dry ice (blue ice) storage box, no professional cooling device, complicated operation and poor cooling effect
