[0006] The exhaust device for thermal insulation external wall provided by the application adopts the following technical scheme: a top plate and a bottom plate are connected with two folding side plates on the opposite side through hinges, two cross support frames are fixedly connected to the opposite side of the two folding side plates, a motor is fixedly connected to the rear inner wall of one of the two cross support frames, and a fan blade is fixedly connected to the output shaft of the motor.

[0007] Preferably, four threaded holes are formed in the opposite side of the two folding side plates, four bolts are inserted into the outer side of the two cross support frames, and eight bolts are threadedly connected with the inner walls of eight threaded holes.

[0008] Preferably, a plurality of roughening grooves are formed in the top side of the top plate and the bottom side of the bottom plate.

[0009] Preferably, the caps of the eight bolts are designed in a hexagonal shape.

[0010] In summary, the application has the following beneficial technical effects:

[0011] 1. By setting the folding side plate, when the exhaust device needs to be disassembled, first take out the two cross supports, then fold the two folding side plates, so that the overall volume can be reduced, after the volume is reduced, the disassembly of the exhaust device can be effectively facilitated, thereby significantly improving the convenience during installation and replacement, and facilitating the use.

[0012] 2. By setting the threaded hole and the bolt, when the cross support is installed, the bolt is screwed into the threaded hole, at this time, the two are matched with each other, the position of the cross support can be effectively fixed, and the stability of the overall expansion can be ensured.

[0017] The technical scheme of the utility model will be described below in conjunction with the drawings Figs. 1-3 Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0018] The embodiment of the application discloses an exhaust device for thermal insulation external wall, referring to Figs. 1-3 , comprising a top plate 1 and a bottom plate 2, two folding side plates 3 are hingedly connected to opposite sides of the top plate 1 and the bottom plate 2, two cross supports 4 are fixedly connected to opposite sides of the two folding side plates 3, a motor 5 is fixedly connected to the inner wall of the rear side of one of the two cross supports 4, and a fan blade 6 is fixedly connected to the output shaft of the motor 5; by setting the folding side plate 3, when the exhaust device needs to be disassembled, first take out the two cross supports 4, then fold the two folding side plates 3, so that the overall volume can be reduced, after the volume is reduced, the disassembly of the exhaust device can be effectively facilitated, thereby significantly improving the convenience during installation and replacement, and facilitating the use.

[0019] In the application, four threaded holes are formed on the opposite side of the two folding side plates 3, four bolts 7 are inserted on the outer side of the two cross support frames 4, and the eight bolts 7 are threadedly connected with the inner walls of the eight threaded holes.

[0020] In the application, a plurality of roughening grooves are formed on the top side of the top plate 1 and the bottom side of the bottom plate 2; by arranging the roughening grooves, when the top plate 1 and the bottom plate 2 are installed, the adhesion area during bonding can be increased when gluing and fixing, thereby improving the bonding firmness.

[0021] In the application, the caps of the eight bolts 7 are hexagonal in design; by arranging the caps of the eight bolts 7 to be hexagonal in design, the worker can conveniently use a tool to tighten the bolts 7, thereby achieving the purpose of saving labor.
