Vacuum desorption oxygen production device

The utility model relates to an oxygen generating device, in particular to a vacuum desorption oxygen generating device. The utility model provides a vacuum desorption oxygen production device with a function of adsorbing dust in air. The vacuum desorption oxygen production device comprises a shell, and a motor is fixedly arranged on the upper left portion of the shell; the rotating plate is fixedly arranged on an output shaft of the motor, and the rotating plate is located in the left part of the shell; the first fixing plate is fixedly arranged in the middle of the shell; and the water cooler capable of cooling gas is fixedly arranged on the first fixing plate. The cooled air entering the water cooler passes through the front adsorption tower and the rear adsorption tower to be subjected to adsorption operation, high-concentration oxygen obtained after adsorption is converged to the upper portion of the front adsorption tower through an adsorption bed layer, and the high-concentration oxygen on the upper po
