The advantage of this embodiment is that the temperature in the incubator 200 is monitored by using the gas temperature sensor, and the controller 132 starts the thermostat to perform the constant temperature treatment on the temperature in the incubator 200 when the temperature monitored by the gas temperature sensor is different from the preset temperature threshold, so as to ensure the constant temperature in the incubator 200; in addition, the gas composition in the incubator body 200 is monitored through the gas composition sensor, namely, under the condition that air impurities appear in the gas in the incubator body 200, the controller 132 starts the fan so as to filter the gas in the incubator body 200, and the automation degree of the whole device is improved.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
