The interiors of the support tubes 31 and the side frames 32 are communicated with each other. The interior of the outer shell 21 and the space between the support tubes 31 and the side frames 32 are filled with an insulation layer 23. The insulation layer 23 is made of insulation material, such as insulation rubber or insulation blanket, and the support tubes 31 and the side frames 32 are made of stainless steel with good heat absorption performance, so as to facilitate the insulation protection of the greenhouse body 1, the support tubes 31 and the side frames 32 through the insulation layer 23 to reduce heat diffusion and loss.

The second motor 624 is fixed on the outer side of the protective shell 621, and the output shaft of the second motor 624 is fixed to the swivel column 622.

[0051] Among them, an air inlet 625 is provided on one side of the protective shell 621 close to the air duct 61 and the heating chamber 71, and an air outlet 626 is provided on the outer side of the protective shell 621, so that the airflow inside the air duct 61 or the heating chamber 71 can flow into the interior of the protective shell 621 through the air inlet 625. When the second motor 624 drives the rotary column 622 to rotate clockwise, it can drive the baffle 63 to rotate, and drive the airflow at the air inlet 625 to be discharged from the air inlet 625. In addition, when it rains or the external humidity is heavy, the setting of the baffle 623 makes it difficult for external rainwater or moisture to be directly discharged into the house, which is close to the traditional ventilation method through a fan, saves the installation of a ventilation valve, is low in cost, and is more practical.

[0052] For further information, please refer to Figure 4 and Figure 6, a heat supply hole 12 is provided on the support tube 31 and the greenhouse body 1, so that the heat on the temperature control tube 41 and the heat transfer oil 44 can be discharged into the heat supply hole 12, and the regulating component 72 includes a heat supply pipe 721, a heat discharge hole 722, a sleeve 723, a frame plate 724, a push plate 725 and a push cylinder 726.

The heat discharge holes 722 are arranged in a straight line on the surface of the heat supply pipe 721. The number of heat discharge holes 722 is set at more than two, so that the heat supply size can be flexibly controlled by controlling the number of heat discharge holes 722 exposed;

[0053] Specifically, the inner wall of the sleeve 723 slides and fits with the heat supply pipe 721. The number of heat supply pipes 721 is set at two or more places. The number of sleeves 723 matches the heat supply pipes 721.
