Background

Respirator equipment is a common respiratory device for providing breathing gases such as oxygen or air through a cylinder. However, during actual use, the respirator apparatus may experience an insufficient air pressure for various reasons, which can seriously affect the life safety of the wearer. At present, the warning device for the respirator can display the pressure condition of the current gas cylinder in real time through the pressure gauge, and when the pressure in the gas cylinder is lower than a set value, the warning whistle is used for carrying out low-pressure warning to remind a user that the storage amount of the gas in the gas cylinder is about to be consumed completely. The low-pressure alarm is a safety protection mechanism triggered when the pressure in the gas cylinder is too low in order to ensure sufficient oxygen supply. When the pressure in the gas cylinder is too low, the alarm whistle can give out alarm sound under the drive of high-pressure air flow, so that a user is reminded of timely replacing the gas cylinder or carrying out inflation treatment.
