The filter net 8 effectively filters the external impurities inhaled by the fan 9 during operation, so as to avoid the hard contact between the solid small particles in the impurities and the fan blades, thereby increasing the service life of the fan 9. The limiting structure 7 facilitates the removal of the filter net 8 for cleaning, thereby increasing the filtering effect of the filter net 8. There is a cavity 3, and electric push rods 1 4 are respectively provided inside the two cavities 3. One end of the two electric push rods 1 4 is fixedly connected to the inner wall of the cavity 3, and the other end is fixedly connected to the cover plate 5. The cover plate 5 is fixedly connected to the sealing layer 6 on the side close to the electric push rod 1 4. A through cavity is provided on the side of the ventilation shell 2 away from the greenhouse body 1. The top and bottom of the through cavity are respectively provided with slide grooves 16. The top and bottom of the filter 8 are respectively fixedly connected to sliders 17. The two sliders 17 are respectively adapted to be connected with the slide grooves 16.

The front side of the sealing plate 13 is fixedly connected to the electric push rod 2 15, and the front end of the electric push rod 2 15 is fixedly connected to the inner wall of the greenhouse body 1.

[0023] like Figure 4 As shown, each group of limiting structures 7 includes an insert rod 701, a retaining ring 702, a fixed block 703, a spring 704 and a pulling block 705. A fixed block 703 is provided inside the inner cavity, and an insert rod 701 is penetrated inside the fixed block 703. One end of the insert rod 701 is sleeved with the retaining ring 702, and the other end passes through the inner cavity and the ventilation shell 2 in sequence and is fixedly connected with the pulling block 705. The outer wall of the insert rod 701 is wrapped with a spring 704, one end of the spring 704 is fixedly connected to the retaining ring 702, and the other end abuts the fixed block 703.

The air is sucked into the interior of the greenhouse body 1, and then the electric push rod 15 contracts to drive the sealing plate 13 to slide in the direction of the electric push rod 15, thereby leaking out the shutters 11, so that the fan 9 and the shutters 11 form convection, thereby increasing the ventilation and heat dissipation effect inside the greenhouse body 1. When used for a long time, the filter screen 8 can be removed and cleaned by pulling out the pulling block 705 through the handle 19, thereby ensuring the filtering effect of the filter screen 8. When the internal temperature of the greenhouse body 1 is low, the electric push rod 15 is extended to make the sealing plate 13 block the shutters 11, and then the heating network 10 is started. Through the cooperation of the fan 9 and the heating network 10, the hot air is input into the interior of the greenhouse body 1, thereby increasing the internal temperature of the greenhouse body 1.
