[0029] The specific implementation of the utility model of the constant temperature incubator will be described in detail below in combination with the drawings.

[0030] Referring to the attached Figures 1-4The constant-temperature incubator of the patent comprises a heat preservation box body 1 and an electric control unit 2 at the bottom of the heat preservation box body 1, and the electric control unit 2 provides power supply and operation control for electrical devices in the heat preservation box body 1. Universal casters 3 are arranged at the bottom of the constant-temperature incubator to facilitate the movement of the device. A heat preservation outer door 4 is arranged on the heat preservation box body 1, and a touch screen 5 is arranged on the outer door 4, which is connected to the electric control unit 2 and displays and interactively controls various parameters of the incubator through the touch screen 5.

[0031] The heat preservation box body 1 comprises a heat preservation cavity 6 and an inner container 7 arranged in the heat preservation cavity 6. Two side air ducts 10 are formed on both sides of the inner container 7 through the hole side plates 8, and an upper cavity 11 is formed on the top of the inner container 7 through the sealing plate 9, which is communicated to the two side air ducts 10. A heating fin 12, a refrigeration evaporator 13, a temperature sensor 14 and a centrifugal fan 15 are arranged in the upper cavity 11. The electric control unit 2 controls the working of the heating fin 12 and the refrigeration evaporator 13 according to the detection information of the temperature sensor 14 to generate constant temperature, and the centrifugal fan 15 circulates the constant temperature air in the upper cavity 11 from one side air duct 10 to the other side air duct 10 through the inside of the inner container 7.
