When air supply is needed, the driving device 10 drives the first air door plate 31 and the second air door plate 32 to rotate synchronously, so that the first air door plate 31 and the second air door plate 32 are opened to form a folded angle, a first air guide outlet 41 is formed between the first air door plate 31 and the air outlet 22, and a second air guide outlet 42 is formed between the second air door plate 32 and the air outlet 22, so that air flow can be guided out to two sides. When the electric air door device is fixedly arranged on a wall, the first air door plate 31 and the second air door plate 32 can send air flow to two sides of the device along the direction parallel to the wall, so that the condition that the temperature is uneven because the air flow is directly sent to the front of the device is avoided.

The electric air door device can be automatically opened when air is supplied without influencing the air supply, and can be automatically closed when the air is not required to be supplied to separate the air supply channel from the room, so that the heat in the room is prevented from being diffused outwards through the air supply channel, the heat is prevented from being dissipated, and the cold air outside the room is prevented from entering the room to cause local indoor temperature reduction and generate cold stress to animals. In addition, because the indoor air supply channel is separated from the air supply channel through the air door plate 30, indoor steam cannot enter the air supply channel and generates condensed water when meeting cold in the air supply channel and the heating equipment, so that the condensed water is prevented from being accumulated in the air supply channel to corrode the air supply channel, and the condensed water is prevented from being accumulated in the heating equipment to cause the fault of the heating equipment. The electric air door device has the characteristics of novel structure and practical function, and has strong practicability.

Although the present invention has been disclosed in the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
