[0002] The demand for cherries in the market is increasing as it is considered one of the high-end fruits with a rich taste and unique flavor. Greenhouse cultivation can provide a stable supply in non-traditional production areas or seasonal extensions, and make cherries more sustainable and reliable to enter the market.

[0003] The temperature and humidity inside the greenhouse have a significant impact on the growth of cherries. Especially in hot weather conditions, the temperature inside the greenhouse may be too high, affecting the development and quality of the fruit. Through the ventilation device, the temperature and humidity in the greenhouse can be effectively adjusted to keep it within the appropriate growth range. When spraying water inside the greenhouse, most spray devices cannot effectively achieve a more uniform spray distribution, resulting in poor ventilation in some areas, affecting the growth balance of plants in the greenhouse, resulting in higher or lower temperatures and humidity in some areas, thereby affecting the healthy growth of plants and the quality of the fruit. When ventilating the greenhouse, most devices open the windows in the greenhouse for ventilation, but after opening the windows, insects can enter the greenhouse through the vents, which may increase the risk of pests and diseases. Some insects may carry pathogens or fungi, spread diseases by touching or eating plants, and cause harm to cherry plants, causing damage to plant leaves, affecting photosynthesis and nutrient absorption, thereby affecting the growth of cherries and fruit quality.

The left and right ends of each of the second triple tubes 312 are connected to the nozzles 313. The second triple tubes 312 are arranged to connect to the nozzles 313, so as to transfer water to the nozzles 313 for spraying.

[0030] like Figure 1 - Fig. 9As shown, the front and rear side walls of the two fixing plates 4 are fixedly connected to the inside of the greenhouse body 1, and air compressors 5 are arranged on the left and right sides of the greenhouse body 1. The internal air of the greenhouse body 1 is replaced by the two air compressors 5, and air is sucked from the outside by one air compressor 5, and the air inside the greenhouse body 1 is discharged by the other air compressor 5. The interior of the two air compressors 5 is fixedly connected with an exhaust port 6, and the front side walls of the two exhaust ports 6 are fixedly connected with a railing 7. The railing 7 is arranged to remove impurities and particles. Insects are blocked to prevent them from entering the interior of the greenhouse main body 1 and causing harm to cherries.

[0035] When ventilation is needed, the air compressors 5 are started, one of which will draw in air from the outside through the exhaust port 6, and then draw the air into the interior of the bellows 10 through the second connecting tube 9 on the delivery pipe 8. The air outlet of the bellows 10 blows air toward the interior of the greenhouse body 1. When the air enters, the external impurities and insects will be blocked by the railing 7 to prevent the impurities and insects from being sucked into the interior of the greenhouse body 1 through the exhaust port 6. In addition, the air outlet of the bellows 10 will be blocked again by the diverter plate 12 to prevent smaller particles and insects from entering the interior of the greenhouse body 1. The other air compressor 5 will extract the internal air of the greenhouse body 1.
