Description

Technical Field

[0001] The invention relates to the technical field of glass curtain walls, and in particular to a ventilation device for a glass curtain wall. Background Art

[0002] Building curtain walls generally use glass, metal, stone, or plastic as curtain wall materials. Glass is often installed on the exterior wall as a light-transmitting material due to its transparency. Due to the temperature difference between the inside and outside of the building, the glass curtain wall requires a ventilation device to balance the temperature inside and outside the glass curtain wall to prevent the glass curtain wall from fogging.

[0003] The ventilation device of the existing glass curtain wall, such as a new type of hidden ventilation system of a unitized curtain wall as described in Publication No. CN112880086A, includes a vent opened on the curtain wall panel. The unitized curtain wall hidden ventilation system also includes a baffle, a first elastic member, a second elastic member, a clamping block, a water collecting shell and a water-swelling waterstop strip. The baffle is located at the vent, and the baffle is slidably connected to the curtain wall panel. The first elastic member is fixedly connected between the baffle and the curtain wall panel, the second elastic member and the clamping block are fixedly connected to the baffle, and the end of the clamping block away from the second elastic member abuts against the curtain wall panel. A clamping groove is provided on the curtain wall panel. After the baffle slides to the position where the baffle is misaligned with the vent, the second elastic member is used to drive the clamping block to be clamped in the clamping groove. The water collecting shell is fixedly connected to the outside of the curtain wall panel, the water collecting shell is communicated with the clamping groove, a water collecting port is penetrated through one side of the water collecting shell, and the water-swelling waterstop strip is located in the water collecting shell.

[0004] In the prior art, the block is controlled to detach from the slot by the expansion of the water stop strip when it comes into contact with water. Since the expansion speed of the water stop strip is slow, the vent cannot be closed in a short time after it rains, which causes rainwater to enter the interior of the curtain wall. Moreover, after the vent is closed, the glass curtain wall is prone to fogging due to the temperature difference between the inside and the outside. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a ventilation device for a glass curtain wall, the purpose of which is to solve the problems raised in the above-mentioned background technology.
