| titleOfInvention | An oxygen breathing mask device |
| abstract | The utility model relates to an oxygen breathing mask device, comprising an oxygen cylinder, an oxygen supply mask, an oxygen supply interface, an oxygen supply pipe, an oxygen bag and an oxygen supply breathing valve; the oxygen supply breathing valve is arranged on the oxygen cylinder and communicated with the oxygen cylinder The oxygen supply breathing valve is provided with a pressure gauge, the oxygen supply breathing valve is connected to one end of the oxygen supply pipe, the other end of the oxygen supply pipe is connected to the oxygen bag, the oxygen supply interface is connected to the oxygen supply interface, and the oxygen supply interface is set On the oxygen supply mask; the design of the utility model is ingenious. By setting the oxygen bag, it cooperates with the one-way valve installed on the oxygen supply interface. After the user inhales, the oxygen bag is pressed and contracted, and the oxygen bag itself has the ability to restore its original elasticity. In this case, the oxygen bag expands and expands to restore the volume before inspiration, which forms the necessary negative pressure environment inside the bag. |
