The deflation component 12 is arranged at the gas supply port 102, and both ends of the deflation component 12 are respectively communicated with the gas supply port 102 and the inside of the housing 1. Among them, the cooling component 10 is used to introduce the low-temperature gas entering the housing 1 through the gas supply port 102 into the inflation mechanism. In this embodiment, the control component 3 can be a control panel structure, and corresponding control buttons are arranged on the control panel. The cooling component 10 can be a refrigeration fan structure, and the inflation mechanism can be an electric air pump structure. A corresponding adapter can be arranged at the connection between the deflation component 12 and the gas supply port 102 to facilitate connection with deflation heads of various models to meet the actual use requirements. Through the control component 3, corresponding control operations are carried out. Through the inflation mechanism, the object to be inflated is inflated.

When the driving assembly 9 drives the transmission assembly 8 to drive the piston assembly 7 to move reciprocally, the airflow rushing out from the third air outlet 601 of the cylinder assembly 6 blows open the retaining ring 5, so that the gas enters the air outlet assembly 4 and rushes out from the first air outlet 401 to inflate the object to be inflated. When the piston assembly 7 moves in the opposite direction, the retaining ring 5 closes the third air outlet 601 again, thereby forming a one-way valve structure.
