With the shortage of energy and the improvement of environmental awareness, traditional large and bulky ventilation equipment can no longer meet the needs of modern buildings and industries. As a new type of ventilation equipment, thin ventilators have gradually become a popular choice in the market with their compact, efficient and environmentally friendly characteristics. Thin ventilators achieve the purpose of efficient ventilation, energy saving and emission reduction, and environmental protection. It can reduce air resistance and noise while ensuring ventilation effect, improve indoor air quality, and create a more comfortable and healthy living and working environment for people.

[0003] The thin roof ventilators currently used are mainly composed of a frame, a flashing plate, an outer protective plate, a gutter, an end sealing plate and an electric valve plate. A single-rod lifting mechanism is used to realize the lifting and lowering of the top valve plate. This lifting valve plate is not stable enough. In strong winds or bad weather conditions, it may cause the ventilator to shake or tilt, and it cannot be used for large or heavy ventilators. The gutter is at the edge or bottom of the ventilator, and the sealing performance is poor, which may cause rainwater or other external debris to enter the room, causing losses or inconveniences. Birds sometimes build nests at the openings of roof ventilators, which not only blocks the vents and affects the ventilation effect, but birds may use various materials such as branches and leaves in the process of nesting, which may block the ventilator and affect the ventilation effect.
