Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of smoke exhaust window, concretely relates to a kind of opening structure of smoke exhaust window. BACKGROUND

[0002] With the acceleration of urbanization and the continuous construction of various buildings, fire safety becomes a crucial concern. Among the many building types, whether it is a high-rise residential building, a commercial complex, or an industrial plant, the effective discharge of smoke during a fire plays a crucial role in ensuring personnel safety and reducing property loss.

[0003] However, the traditional smoke exhaust window has serious hidden dangers. When not in use for a long time, the smoke exhaust port is usually connected to the outside environment, and the location is relatively concealed. Insects and birds are likely to find suitable habitats here and choose to build nests in the smoke exhaust port. These nests are mostly made of twigs, dry grass, soil and various debris. Over time, they will gradually accumulate and adhere tightly to the inner wall of the smoke exhaust port, severely reducing or even completely blocking the smoke exhaust passage. When a fire occurs, smoke should be quickly discharged through the smoke exhaust port to ensure that the evacuation path for indoor personnel is clear and visible, and to reduce the harm of toxic and harmful smoke to the human body. However, due to the blocked smoke exhaust port, smoke cannot be smoothly discharged, and smoke will quickly accumulate indoors, causing a sharp decrease in indoor visibility, making it difficult for people to identify the escape direction, and also causing the concentration of toxic gases in the room to rise rapidly, greatly threatening the safety of personnel and seriously affecting the smoke exhaust effect of the smoke exhaust window, making it difficult to provide effective support for fire rescue and personnel escape. Therefore, the utility model is proposed. CONTENT OF THE UTILITY MODEL
