The storage tube 1 provides a fixing point for the air intake tube 2, the first output tube 4, the moving switch 8, the electric telescopic rod 9 and the power connection line 16 installed on its outer surface, and at the same time provides a storage space for the Freon gas stored inside it, so as to facilitate the subsequent output of the Freon gas. The air intake tube 2 is installed through one side of the storage tube 1. Before using the device, the external pipeline is connected to the air intake tube 2. At this time, the air intake tube 2 transports the Freon gas to the inside of the storage tube 1, and at the same time provides a fixing point for the one-way valve 3 installed inside it. The one-way valve 3 is installed inside the air intake tube 2. The one-way valve 3 is installed inside the air intake tube 2 to allow the air inside the air intake tube 2 to enter.

At this time, the power plug 17 transmits electrical energy to the inside of the power connection line 16, and the power connection line 16 transmits electrical energy to the inside of the moving switch 8 and the pressure detector 13 respectively. Then, the first manual throttle valve 11 is turned by external force to drive the internal connection of the connecting shell 5. When it is necessary to speed up the delivery speed of the Freon gas, it can be turned by external force. Move the moving switch 8. At this time, the moving switch 8 transmits electric energy to the inside of the electric telescopic rod 9. The electric telescopic rod 9 extends, driving the pressure head 10 installed at its tail end to move upward. The pressure head 10 moves upward under the drive of the electric telescopic rod 9, and generates pressure on the Freon gas inside the storage tube 1, so that the Freon gas is quickly transported to the inside of the first output pipe 4.
