The invention discloses a high-
humidity N2 generator, which comprises a water cavity, a gas-liquid confluence device, an atomization cavity and a mist leading-out device. A water inlet
pipe is installed in the water cavity, a
liquid level sensor is installed on the water inlet
pipe and used for giving off an water supplying alarm, when the liquid level in a low position; an atomization cap is arranged at the top of the gas-liquid confluence device, the atomization cap is located in the atomization cavity, a plurality of liquid inlet holes and
backflow holes, which are communicated with the water cavity are formed in the bottom of the gas-liquid confluence device, an overflow port and a
nitrogen inlet are formed in the side face of the gas-liquid confluence device; the mist leading-out device is provided with a leading-out
pipe, a wet
nitrogen outlet is formed in the upper end of the leading-out pipe, the lower end of the leading-out pipe extends into the atomization cavity, and a plurality of hole channels communicated with the atomization cavity are formed in the side face of the lower end of the leading-out pipe. The N2 generator is reasonable in design, simple in structure, convenient to operate, capable of providing high-
humidity nitrogen, effectively controlling the nitrogen
humidity, and meeting the use requirements, high in stability, effectively guarantees the stabilityand durability, is capable of automatically controlling water feeding when water in the water cavity is insufficient, can automatically give an alarm when water overflowing happens, and has a popularization value.
