[0002] As society continues to progress, the traditional agricultural production model can no longer meet the needs of the development of modern civilization. New types of facility agriculture are sought after by industry insiders. The so-called agricultural equipment is actually mainly greenhouse facilities, which are not restricted by time and space and can carry out agricultural production in special environments such as plateaus, deep mountains, and deserts.

[0003] A greenhouse ventilation device disclosed in the Chinese utility model patent application disclosure CN218353630U has the advantages of preventing mosquitoes from entering, facilitating the replacement of filters, and heating the interior in cold weather. However, the greenhouse ventilation device still has disadvantages: First, during actual use, the greenhouse ventilation device needs to be manually turned on to ventilate the interior of the greenhouse. In this case, it may not be possible to accurately grasp the ventilation time, and the user can only rely on rich experience. The low fault tolerance rate may easily lead to problems. Second, the greenhouse ventilation device uses a filter to isolate external dust and mosquitoes. However, during actual use, some odorous gases will be generated inside the greenhouse, which may be released into the air during the ventilation process, causing discomfort to the staff.
