[0002] A grain bin is a container for storing grain. To avoid excessive moisture in the grain inside the grain bin, the grain stacked for a long time needs to be kept ventilated to prevent mildew during the fermentation process of the stacked grain.

[0003] The existing ventilation devices are divided into active ventilation or passive ventilation. Whether it is active ventilation or passive ventilation, ventilation openings are left. During the ventilation process, some pests will enter the grain bin through the ventilation holes, resulting in the grain in the grain bin being damaged by insects.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN218604081U discloses a grain bin ventilation device with insect prevention. This structure uses the honeycomb holes opened on the mounting plate to block insects, and the connecting piece and the embedded pipe are used to cooperatively connect the embedded box. At the same time, insect repellent is placed inside the embedded box, and the insect repellent volatilizes into the ventilation pipe and is carried out by the airflow of the ventilation fan, driving away the insects attached to the mounting plate, achieving the effect of insect repellent and prevention.

[0005] However, when this structure is actually used, the honeycomb holes opened on the mounting plate are easy to be blocked by dust and the remains of pests while blocking insects, and it is difficult to clean, thereby affecting the final ventilation effect. In view of this, the utility model provides a special environmental protection ventilation fan for grain bins. Summary of the Utility Model
