Rapid heating and cooling device for germ detection

The invention relates to the technical field of pathogen detection, and discloses a rapid heating and cooling device for pathogen detection.The rapid heating and cooling device comprises a shell mechanism, and the shell mechanism further comprises an equipment shell. By means of the characteristic that heat can be rapidly generated when air is pressed, when temperature needs to be increased, a pathogen detection bottle and a sealing plate are installed on the inner wall of an installation opening; a closed space is formed among the equipment shell, the fixing plate and the extrusion plate, the rotating disc rotates under the influence of the power motor, the rotating disc drives the control rod to move upwards, and when the control rod moves upwards, after gas in the closed space is compressed, the distance between air molecules is shortened, and the air molecules are separated. The air in the closed space is pressed to quickly generate heat, and before the control rod reaches the highest point, the rotating
