The ventilation opening comprises a profile frame, shutters are rotatably connected into the profile frame, a bimetal piece capable of pushing the shutters to rotate is arranged on the profile frame, and is wound into a torsional spring shape to form a bimetal spring, a positioning column is arranged on the profile frame, the inner end of the bimetal spring is fixed to the positioning column, the outer end of the bimetal spring extends outwards to form a driving end, the bimetal piece is connected with a connecting plate, and an opening allowing the driving end of the bimetal spring to extend in is formed in the connecting plate. Human intervention is not needed, and extra energy for controlling opening and closing of the shutters does not need to be consumed.

Description

technical field [0001] The invention belongs to the field of ventilation devices, and more specifically relates to a ventilation opening whose switch is automatically controlled according to temperature. Background technique [0002] Ventilation openings refer to some ventilation holes in the walls or roofs of some houses, which can be seen everywhere in houses in ancient times, and some ventilation bricks with decorative stripes, fixed louvers or movable louvers will be set at the ventilation openings.
