Description

Technical Field

[0001] The utility model relates to the technical field of planting greenhouse ventilation devices, in particular to a multifunctional greenhouse automatic ventilation device. Background Art

[0002] When planting Gongcai, in order to ensure the survival rate and facilitate management, Gongcai is usually planted in a corresponding greenhouse. The greenhouse provides a suitable growth environment for crops through light-transmitting materials and thermal insulation structures. However, most greenhouses are in a closed environment, and the temperature, humidity, gas composition, etc. in the greenhouse are easy to accumulate, causing environmental deterioration and affecting crop growth.

[0003] In the management process of greenhouses, ventilation is one of the key factors to ensure the normal growth of crops and increase yields. Good ventilation can effectively adjust the environment in the greenhouse, remove excess heat, moisture and harmful gases, and introduce fresh air to maintain a suitable environment for crop growth. However, traditional greenhouse ventilation methods often rely on manual operation. In specific operations, the curtains of the greenhouse are directly opened manually to ensure air circulation. After the ventilation is completed, the curtains are manually pulled up. This operation is not only inefficient, but also time-consuming and requires long-term manual operation, which brings inconvenience to users. In view of this, we propose a multifunctional greenhouse automatic ventilation device. Utility Model Content
