[0003] Existing nitrogen and oxygen mixing devices introduce a certain amount of nitrogen and oxygen into a mixing chamber and mix them. However, since the pressure, humidity and temperature in the mixing chamber cannot be adjusted, when mixing nitrogen and oxygen, it is impossible to simulate the mixing conditions of nitrogen and oxygen in different environments, which is relatively inconvenient.

[0004] Therefore, an environmental simulation nitrogen-oxygen mixing device has been developed that can adjust the pressure, humidity and temperature in a mixing chamber so as to simulate the mixing conditions of nitrogen and oxygen in different environments. Utility Model Content

[0008] Preferably, a pressurizing pipe and a valve are further included. The upper middle side of the mixing chamber is connected to the pressurizing pipe, and the upper part of the pressurizing pipe is rotatably connected to the valve.

[0009] Preferably, a pressure gauge is further included, and the upper side of the pressurized pipe is connected to the pressure gauge.

[0010] Preferably, a water pipe and a nozzle are further included. The water pipe is connected between the base feet and is located outside the mixing chamber. A plurality of nozzles are connected to the front and rear parts of the mixing chamber, and the nozzles are all connected to the water pipe.

The inner side of the mixing chamber is connected to a plurality of temperature control wires, and the front side of the mixing chamber is connected to the controller.
