Air respirator with pressure head-up system

Abstract

The invention discloses an air respirator with a pressure head-up system. The air respirator comprises an air capacity detecting device for an air storing bottle, and an air capacity display device for the air storing bottle, wherein detecting data is transferred between the detecting device and the display device in a wireless manner; a wireless data delivery module is arranged in the detecting device, and a wireless data acceptance module is arranged in the display device; the two modules are connected in a wireless manner after signal matches; the display device is arranged in a face guard of a breathing apparatus in a clamping and connecting manner to be fixed between a face guard window and a respirator of the face guard to be capable of being used with different kinds of face guards in a combined manner; the contact position of the display device and the face guard window is arranged into the shape of a spherical surface jointed to the face guard window; the detecting device is connected with the air storing bottle through a high pressure gas pipe; the detecting device is also provided with a falling warning device for users.

Description

technical field [0001] The invention relates to an air respirator equipped with a pressure head-up system, in particular to a detection device and a display device of the pressure head-up system. Background technique [0002] Positive pressure air respirator is a self-contained open isolating respirator with compressed air as the breathing source, and the air supply method is positive pressure, that is, when the person wears the respirator, the entire respiratory system is always in contact with the outside world. Under the conditions of isolation and internal pressure higher than that of the external environment, toxic and harmful gases from the outside cannot enter the respiratory system during the whole protection process, ensuring safe and reliable respiratory protection. The equipment has been widely used in many fields such as fire protection, chemical defense, anti-terrorism, emergency response, and emergency rescue. [0003] With the rapid development of my country'...

AI Technical Summary

Problems solved by technology

Since the display device and the detection device of the respirator pressure head-up system are in one-to-one correspondence, the respirator mask integrated with the display device also corresponds to the detection device, while the mask of a traditional respirator is a common part. It can be matched with various respirators arbitrarily, which leads to great inconvenience in the use, management, maintenance, maintenance and other work of the mask integrated with the pressure head-up system display device, and also greatly reduces the versatility, safety, and reliability of the equipment. reliability
