[0034] In this embodiment: by setting up a gas hose 31, the gas hose 31 has good flexibility and sealing performance, and can deliver gas from the air pump 34 to the air bag 23 without affecting the installation position of the fan. By setting up the solenoid valve 32, the on and off of the gas can be accurately controlled to realize automatic control of the inflation and deflation of the air bag 23.

[0036] Specifically, such as Figure 5 As shown, the surface of the gas delivery hose 31 is covered with a limiting net 5, and the surface of the limiting net 5 is coated with anti-corrosion paint.

[0037] In this embodiment: by providing a sealing ring 4, a good seal can be formed at the connection between the solenoid valve 32 and the gas hose 31 to prevent gas leakage.

[0041] Working principle: First, the user determines the location suitable for installing the fan in the automobile air-conditioning system. Then, when preparing to install the automobile air-conditioning evaporative fan, the fan body 1 is placed near the installation location. After that, the user turns on the power and starts the air pump 34. At this time, the gas generated by the air pump 34 is transmitted through the air supply pipe 33. Then, the user energizes the solenoid valve 32 and starts it. When the solenoid valve 32 is in the open state, the gas smoothly enters the air supply hose 31 through the air supply pipe 33. The air supply hose 31 transports the gas to the air intake pipe 24, and the air intake pipe 24 then introduces the gas into the airbag 23, prompting the airbag 23 to start inflating. As the airbag 23 inflates, under the precise positioning action of the limit groove 22, the airbag 23 expands evenly and fits tightly to the installation location. Finally, when the fan needs to be disassembled, just close the solenoid valve 32 to deflate the airbag 23, and the fan body 1 can be easily removed from the installation location.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
