Utility Model Registration No. 20-366083 "Simple Air Re-Hop Hopper" installs a three-way exhaust pipe on the upper surface of the air bag that can be tied with a string, and checks the carbon dioxide removal passage through the lower exhaust and side intake holes of the three-way exhaust pipe. A valve is installed, and a corrugated pipe hose is installed at the outlet of the upper end and connected to the mask. An opening means having a sinking is installed at the side of the exhaust pipe inside the air bag, and a small compression communication is installed at the opening means.

When the small compression communication is completely screwed to the opening means, the top of the small compression communication is opened by sinking and oxygen is injected into the air bag, and the oxygen filled in the meat bag is passed through the intake hole provided with a check valve. As it flows in, it is sprayed through a corrugated hose to a mask.

However, this means that the opening means, the small compression communication and the three-way exhaust pipe should be installed inside the air bag, but there is a problem in that they cannot be easily installed. There is a problem that wastes resources, there is a problem that can not control the injection amount of oxygen because it is not equipped with a supply control function of oxygen is rapidly exhausted and the use time is shortened.

The present invention is to provide a simple oxygen supply using a further improved oxygen cartridge to solve the above problems.
