Description

Technical Field

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

[0002] A greenhouse, also known as a hothouse, refers to a room with facilities such as cold protection, heating and light transmission, which is used to cultivate thermophilic plants in winter. In seasons that are not suitable for plant growth, it can provide a growth period and increase yields. It is mostly used for the cultivation or seedling raising of thermophilic vegetables, flowers, trees and other plants in low temperature seasons. For a greenhouse, ventilation equipment is indispensable to provide ventilation for the greenhouse.

[0003] The publication number is CN209171038U, which is an intelligent multi-span greenhouse ventilation and insect-proof device. It is composed of a ventilation hood, an insect-proof net is embedded on the ventilation hood, an equipment box is arranged at the bottom of the ventilation hood, the equipment box and the ventilation hood are an integrated structure, a ventilation device is arranged inside the ventilation hood, the ventilation device is composed of a ventilation fan and a transmission box, a motor is arranged inside the transmission box, the motor is connected to the ventilation fan through a bearing, insect-proof net embedding holes are arranged on the top and both sides of the inner wall of the ventilation hood, a power transmission hole is arranged on the inner wall of the bottom of the ventilation hood, a power transmitter is arranged on the power transmission hole, and a warning light is arranged outside the equipment box. Through the design of the ventilation device with an insect-proof net, when the ventilation device is running, the insect-proof net will be energized through the power transmitter, and insects will not be able to pass through the ventilation device. The design of the insect-proof net effectively prevents insects from entering the greenhouse and causing damage to flowers and plants.
