Building body exterior ventilation device

Abstract

The invention discloses a building body exterior ventilation device. The building body exterior ventilation device comprises a fixed plate fixedly installed on the wall surface of the outer side of a building body. An assembling cavity is formed in the end surface of the outer side of the fixed plate. The upper end and the lower end of the assembling cavity are open. The upper opening end of the assembling cavity is provided with a first magnetic attraction box. The lower opening end of the assembling cavity is provided with a second magnetic attraction box. A through groove is formed in the middle of the first magnetic attraction box from top to bottom in a penetrating mode. The through groove is internally provided with a transparent moving plate. A breathable cavity is formed in the middle position of the fixed plate. The magnetic attraction boxes are each provided with an electromagnetic set. The upper surface and the lower surface of the outer side end of the transparent moving plate are each provided with a magnetic attraction part. The building body exterior ventilation device is simple in structure, the ventilation device is arranged at the exterior of the building body, in this way, the area of the formed breathable cavity can be fully opened during being used, the transparent moving plate does not occupy the area of the building body, the ventilation device is changed into an outdoor structure, a controller can be remotely controlled to close the ventilation device, the structure is very simple, and the cost is fairly low.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device outside a building body. Background technique [0002] The ventilation system of a building is generally a window set in the middle of the wall. There are many window structures in the prior art, including push-out type and two-way movable type. The use of the push-out type structure is more dangerous. It is easy to be destroyed. Although the two-way movable structure has no structural danger of extrapolation, one area can only have half of the ventilation area, that is, only half of the ventilation area can be used, and the other half of the area overlaps each other to achieve closure. This leads to a waste of space usage. [0003] Furthermore, the use of windows occupies the area of ​​the vents, which is limited in use, while the area outside the building is unlimited. If the area of ​​glass is moved to the outside of the building, it will certainly increase the usa...

[0002] The ventilation system of a building is generally a window set in the middle of the wall. There are many window structures in the prior art, including push-out type and two-way movable type. The use of the push-out type structure is more dangerous. It is easy to be destroyed. Although the two-way movable structure has no structural danger of extrapolation, one area can only have half of the ventilation area, that is, only half of the ventilation area can be used, and the other half of the area overlaps each other to achieve closure. This leads to a waste of space using

[0003] Furthermore, the use of windows occupies the area of ​​the vents, which is limited in use, while the area outside the building is unlimited. If the area of ​​glass is moved to the outside of the building, it will certainly increase the usable area inside the building

[0004] In addition, there are currently many automatic door and window closing systems, but most of them have complex structures and high purchase costs, so many people do not choose to install them.
