Problems solved by technology

In this case, for example, when a team of firefighters is working on the same scene, the alarm sounds from the respective air breathing apparatus can be very confusing
In addition, there are often many other rescue equipment at the rescue site, and a large part of these equipment also have similar buzzer alarm devices. Therefore, in such a noisy environment, air respirator users must accurately identify whether the alarm sound is It is very difficult for the air breathing apparatus used by oneself to emit
[0005] For example, the traditional alarm is to emit a sound greater than 90 decibels when the gas pressure in the air respirator cylinder is reduced to 5.5MPa±0.5MPa,...

Embodiment Construction

[0050] The embodiments of the present invention will be exemplarily given below with reference to the drawings. It should be understood that reference to various embodiments does not limit the scope of the present invention. In other words, any examples given in this specification are not restrictive, but merely illustrative.

[0051] In one embodiment of the present invention, an air breathing apparatus is provided, which is provided with an air supply source and a vibrating alarm device. The air supply source is configured to supply air to the air breathing apparatus. When the input pressure of the gas drops below the predetermined input pressure, the vibrating alarm device vibrates to alert the user.

[0052] In a preferred embodiment of the present invention, the air breathing apparatus is further provided with a pressure reducing device, and the air breathing apparatus is arranged such that when the input pressure of the gas from the air supply source is higher than a predete...

Abstract

The invention relates to an air respirator. The air respirator comprises an air supply source and a vibrating alarm device, wherein the air supply source is used for supplying air to the air respirator. The air respirator is characterized in that: when the input pressure of the air from the air supply source declines to be lower than the predetermined input pressure, the vibrating alarm device generates vibration to give an alarm to a user.

Description

Technical field [0001] The invention relates to an air respirator, in particular to an air respirator with an alarm function. Background technique [0002] Air respirator is a kind of equipment mainly used to provide effective respiratory protection to prevent inhalation of toxic and harmful substances when the user enters an oxygen-deficient, toxic and harmful gas environment. One application area where air breathing apparatus is used very frequently in such places is the fire rescue scene. [0003] During the use of the air respirator, when the air respirator may not be able to provide effective respiratory protection due to insufficient air pressure, it is necessary to send an alarm message to the user in time so that the user can grasp the air source of the air respirator in time Situation, and promptly evacuate from the dangerous environment or take other countermeasures. Since air respirators are usually used in very dangerous environments such as oxygen-deficient environme...
