Microbial incubator with temperature control function

The utility model provides a microbiological incubator with a temperature control function, which relates to the technical field of microbiological culture and comprises an incubator body, a culture cavity is arranged in the incubator body, a placing rack is mounted at the lower end in the culture cavity, a plurality of electric heating tubes are mounted at the upper end in the culture cavity, and the electric heating tubes are connected with the placing rack. An auxiliary temperature control mechanism is arranged at one end in the incubator body. The interior of the culture cavity is heated through the electric heating pipe, then the suction fan injects air in the culture cavity into the refrigeration fins through the through holes, the air is cooled by the refrigeration fins, and then the air is injected into the culture cavity through the temporary storage groove and the exhaust holes. Then hot air and cold air are mixed and blown through a fan, so that the temperature in the incubator body is more accurat
