[0023] In this embodiment, oxygen enters the humidification bottle 2 through the connection between the oxygen input tube 4, the second through hole 19, and the humidification input tube 11, thereby humidifying the oxygen. At the same time, the first through hole 18 is connected to the oxygen output tube 5 and the humidification output tube 13, which is beneficial to the output of the humidified oxygen in the humidification bottle 2, thereby avoiding the oxygen drying and affecting the patient's use. The rotating drum 15 is rotated to connect the longitudinal hole 20 with the atomization output tube 6. At this time, the oxygen input tube 4 is connected to the third through hole 26. Through the setting of the transverse hole 27, oxygen can be directly output from the atomization output tube 6, thereby avoiding the oxygen passing through the humidification bottle 2 to cause the medicine to be diluted, thereby improving the practicality of the equipment.
