Abstract

The invention discloses a pressure display device of an air respirator. The pressure display device of the air respirator is characterized by comprising a shell, an inlet connection, a pressure measurement device and an air pressure sensing device. The pressure measurement device and the air pressure sensing device are respectively connected on the inlet connection. The pressure measurement device and the air pressure sensing device together form a pressure display device body which is accommodated in the shell. The pressure display device of the air respirator has the advantages that the integrated pressure display device is simple in structure, convenient and fast to assemble and capable of timely sending air pressure information of the air respirator to a saving alarm and then sending the pressure information to a backfield receiving device, backfield command staff are beneficial to timely knowing scene conditions and giving a command, and accidents are prevented from happening.

Description

technical field [0001] The invention relates to an accessory of an air respirator, in particular to a pressure display device of the air respirator. Background technique [0002] Air breathing apparatus is a life-saving equipment for firefighters or emergency rescue personnel to safely and effectively carry out fire extinguishing, emergency rescue and rescue work in various environments such as dense smoke, poisonous gas, steam or lack of oxygen. At present, air respirators include gas cylinders, masks, pressure display devices and alarm devices. The traditional pressure display device includes a mechanical pressure gauge and an alarm whistle, which are connected with a high-pressure air duct through a connector. The mechanical pressure gauge is hung in front of the user for viewing at any time. When the pressure in the gas cylinder drops to the alarm threshold, the alarm whistle will start to alarm continuously, reminding the user to evacuate the scene to a safe place to ...
