Description

PNEUMATIC REGULATOR

Field of the Invention [0002] The present invention relates to a pneumatic regulator, and more particularly, to a pneumatic regulator connected to an air purifier as well as a portable air container.

Portable oxygen supply is of utmost importance for rescue operations in a fire-scarce fire scene or in a disaster-prone environment.

In Korean Registered Utility Model No. 20-0234760 (published Jun. 2001, hereinafter referred to as the present document), a portable oxygen supply device is described. The oxygen supply device of the present document is provided with an oxygen container for supplying oxygen at a place where oxygen is deficient and a regulator detachably installed in the oxygen container. The regulator serves to regulate the amount of oxygen supplied from the oxygen container. The oxygen that has passed through the regulator is delivered to the user's breathing apparatus, such as through a connecting hose. On the other hand, the user can adjust the amount of oxygen through the regulator to facilitate breathing considering the wearing environment of the respiratory apparatus.

However, such an oxygen supply device is a device that supplies oxygen to only one wearer. Therefore, a worker performing a rescue operation in a fire scene or a disaster environment has a lot of restrictions on rescuing others. In other words, it often happens that oxygen is supplied by a worker to supply oxygen to a large number of people. In an environment full of toxic gases, the worker puts his / her breathing device off and puts it on another person is a life-threatening act of the worker .
