[0031] The temperature inside the installation box 1 is detected by the temperature detector 7, and the detection data is transmitted to the external display screen. When the temperature inside the installation box 1 needs to be adjusted, the first motor 21, the electromagnetic plate 25 and the four groups of one-way valves 29 are started. When the temperature detector 7 detects that the temperature inside the installation box 1 is too low, the external hot air is transmitted to the piston cylinder 26 through the front end connecting pipe 28 of the piston cylinder 26 at the top front end of the installation box 1.

When cooling is required, the cold air is transported to the piston cylinder 26 through the right end connecting pipe 28 of the piston cylinder 26 at the rear end of the top of the installation box 1. When heating is required, the hot air is transported to the piston cylinder 26 through the right end connecting pipe 28 of the piston cylinder 26 at the rear end of the top of the installation box 1, so as to complete the temperature adjustment inside the installation box 1, prevent the temperature in the electrostatic spinning equipment from being too high or too low, and block the equipment channel or pipeline, so as to prevent the normal operation of the production line from being affected by the blockage.
