Description

Technical Field

[0001] The invention relates to the technical field of ventilation adjustment devices, and in particular to a ventilation adjustment device for buildings. Background Art

[0002] As is known to all, with the continuous improvement of people's requirements for indoor environmental comfort and energy efficiency, ventilation systems play a pivotal role. For example, the prior art CN216048172U discloses a ventilation device for municipal construction projects that is easy to adjust the angle, including a ventilation frame and a fan. The ventilation frame is provided with an air trough, and the fan is installed inside the air trough. The inner wall of the air trough is fixedly connected to a plurality of fixed shafts, and the side surface of the fixed shaft is rotatably connected to a guide plate; the angle of the guide plate can be adjusted as a whole to achieve the change of the ventilation angle, without the need for manual adjustment, thus avoiding damage to the guide plate, and the guide plate will not be reset due to the influence of gravity.

[0003] However, most of the existing traditional building ventilation and adjustment devices adopt a fixed air outlet design, or can only perform simple adjustments, which makes it difficult to adapt to the complex and changeable indoor and outdoor environment. Due to the significant difference in temperature and humidity between indoor and outdoor in different seasons and time periods, such as hot and humid in summer and cold and dry in winter, if the ventilation device cannot be flexibly adjusted based on this, it will either introduce unsuitable air, affecting the indoor temperature and humidity balance and reducing comfort, or fail to fully utilize the potential of natural ventilation, resulting in energy waste. In addition, some existing adjustable air outlet structures cannot be effectively positioned and fixed after adjustment, especially the wind direction is more critical. If the air outlet is fixed when strong wind blows directly, it may cause whistling and filling, destroying the stability of indoor air flow, and even damaging the device. It is also impossible to accurately adjust the ventilation volume and airflow direction as needed.
