Smoke and heat exhaust ventilator

Abstract

The present invention provides a smoke and heat exhaust ventilator, which includes a pedestal, a diversion cover and a horizontal fan blade. The pedestal is provided with an assembly portion and external surface with an air vent. The diversion cover is assembled onto the external surface of the pedestal being hollow and being provided with an accommodating space, the inner end of which is connected to the air vent. The diversion cover is also provided with a lateral air inlet/outlet connected to the accommodating space. The horizontal fan blade is mounted into the accommodating space and comprised of a rotating shaft and a few blades. The external side of the horizontal fan blade aligns with the lateral air inlet/outlet of the diversion cover, whilst the inner end of horizontal fan blade aligns with the air vent of the pedestal.

1 . A smoke and heat exhaust ventilator, comprising:
 a pedestal, having an assembly portion and an external surface, said external surface having an air vent reserved at a preset location thereon;   a diversion cover, being assembled onto said external surface, being hollow and forming an accommodating space with an inner end connected to said air vent, said diversion cover having a lateral air inlet/outlet connected to said accommodating space; and   a horizontal fan blade, mounted into said accommodating space, said horizontal fan blade comprising a rotating shaft and a plurality of blades radially arranged onto said rotating shaft, an external side of said horizontal fan blade being aligned with said lateral air inlet/outlet of said diversion cover, said horizontal fan blade having an inner end aligned with said air vent.   
   
   
       2 . The ventilator defined in  claim 1 , wherein the pedestal is a plate, said plate having an oblique surface formed in peripheral. 
   
   
       3 . The ventilator defined in  claim 1 , wherein said lateral air inlet/outlet has a curved baffle plate placed therein at a predefined depth, said curved baffle plate being formed when said external surface protrudes until exceeding a center of said rotating shaft of said horizontal fan blade. 
   
   
       4 . The ventilator defined in  claim 1 , wherein said diversion cover is provided with an oblique flange opposite to the lateral air inlet/outlet. 
   
   
       5 . The ventilator defined in  claim 1 , wherein said pedestal and said diversion cover have a solar panel mounted thereon.
