Abstract

The invention relates to a positive-pressure automatic temperature control refrigerating fire-fighting air respirator for fire equipment, wherein the bottom of an assembly box is provided with a carbon dioxide flask, an air flask, a freezer and a fixed sleeve; the right end of the fixed sleeve is fixed with an air reducing valve and the left end of the fixed sleeve is fixed with a carbon dioxide reducing valve; the air reducing valve is connected with an air outlet nipple of the air flask and the carbon dioxide reducing valve is connected with an air outlet nipple of the carbon dioxide flask; air outlets of the air reducing valve and the carbon dioxide reducing valve are respectively connected with respective air inlets of the freezer through ducts; an air outlet of the freezer is connected with an air suction mask; the inside of a box body is also provided with an electric automatic temperature control part; and the inner surface of the assembly box is uniformly laid with a layer of heat-insulating materials. The positive-pressure automatic temperature control refrigerating fire-fighting air respirator has a simple structure and light weight, is convenient to be carried and operated by a single person, utilizes carbon dioxide to freeze air in the respirator, provides the air at a temperature of between 17 and 40 DEG C and the service time of 15 minutes in a high-temperature environmental field with 220 DEG C for firefighters and succors, and is an ideal high-temperature environmental lifesaving appliance.

Description

technical field [0001] The utility model relates to a fire-fighting equipment, in particular to a positive-pressure automatic temperature-control refrigeration type fire-fighting air respirator. Background technique [0002] The positive pressure fire-fighting air respirator manufactured according to the regulations of my country's public safety industry standard GA124-2004, its gas storage cylinder is directly exposed to the outside, and when rescued in a high-temperature environment, the temperature of the air inhaled by rescuers will rise sharply with time. In severe cases, it will cause damage to the pharynx and lungs, loss of rescue capabilities, and even self-injury of rescuers. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a positive pressure automatic air compressor with simple structure, thermal insulation and carbon dioxide refrigeration, and automatic temperature control wi...
