Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse ventilation, in particular to a ventilation device used for a greenhouse. Background Art

[0002] In recent years, with the rapid development of facility agriculture, more and more farmers are planting greenhouse vegetables. Greenhouses are facilities that artificially create various conditions such as temperature, light, water, air, fertilizer, etc. that are conducive to vegetable production. They can be manually operated and regulated. In the greenhouse, a microclimate suitable for crop growth can be artificially created according to the biological characteristics of crops. Now, in order to improve the yield and quality of crops, the use of greenhouses is becoming more and more widespread. Greenhouses are mainly used to lock the temperature and provide a suitable temperature for crops. However, sometimes the sun shines for too long and the temperature in the greenhouse is too high. Excessive temperature is not conducive to the growth of crops. Therefore, vents need to be set to allow air circulation inside and outside the greenhouse to maintain a suitable temperature.

[0003] Authorization announcement number CN217657375U discloses a ventilation device for greenhouses. This patented technology can make the length direction of the negative pressure pipe always consistent with the wind direction through the guiding effect of the guide plate. The way the wind flows through the negative pressure pipe can make the pressure of the auxiliary ventilation pipe close to the negative pressure pipe end less than the pressure of the auxiliary ventilation pipe close to the main ventilation pipe end, so that a pressure difference is generated at both ends of the auxiliary ventilation pipe. At this time, the air in the main body of the greenhouse will be discharged through the main ventilation pipe, the auxiliary ventilation pipe and the negative pressure pipe to achieve ventilation of the main body of the greenhouse; however, the ventilation structure in this scheme is relatively complicated, and multiple pipes are used to ventilate the greenhouse, which has a poor effect, affects the ventilation quality, and easily leads to the loss of heat in the greenhouse. The air is not purified and harms crops, and there are small flying objects inside the greenhouse that will block the ventilation duct and affect the exhaust effect of the ventilation duct. Therefore, a ventilation device for greenhouses is needed to improve the above problems. Utility Model Content
