It can be connected to a hose so that exhaled breath can come in and out.

For example, the second oxygen mixing unit 200 may be made of a cylindrical box with flexible elasticity mounted inside the case unit 610 and having an inlet and an outlet formed at the top and bottom, and is connected to a hose to form the mask 20. It can play a role in supplying (breathing in) oxygen to the body.

For example, when the electronic board operates normally and the sensor unit 110 detects that the oxygen supply is insufficient, the first oxygen supply regulator 221 is opened by electronic control to provide the necessary oxygen for breathing. Oxygen can be supplied intermittently at the required oxygen concentration. At this time, the second oxygen supply regulator 222 is closed. For example, the first oxygen supply regulator 221 and the second oxygen supply regulator 222 operate in reverse operation with each other (if the first oxygen supply regulator 221 is on, the second oxygen supply regulator 222 is off, and conversely, the first oxygen supply regulator 222 is turned on.
