Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an exhaust fan of a greenhouse temperature control system comprises a device body 1, two bearings 2 which are symmetrical to each other are fixedly sleeved on the inner wall of the device body 1, insect-proof nets 3 are fixedly mounted on the front surface and the back surface of the device body 1, an air breather 4 is fixedly sleeved inside the two bearings 2, three fans 5 which are uniformly distributed are fixedly mounted inside the air breather 4, a large gear 6 is fixedly sleeved on one side of the air breather 4 extending to the outside of the device body 1, a small gear 7 is meshed outside the large gear 6, an output shaft of a motor 8 is fixedly sleeved inside the small gear 7, a mounting box 9 is fixedly mounted on the side surface of the device body 1, and the motor 8 is fixedly mounted inside the mounting box 9.

The device body 1 comprises a device shell 11, a cylindrical hole 12 is formed in the device shell 11, and rectangular holes 13 are formed in the front surface and the back surface of the device shell 11;

the insect-proof net 3 is fixedly arranged in the rectangular hole 13, so that external mosquitoes or weeds can be prevented from entering the device shell 11;
