Abstract
A smoke exhauster including a top plate, a right plate and a left plate. Both left and right edges of the top plate are bent downwardly and then inwardly for 180 degrees so as to form basic strip portions containing a receiving space. The top edges of left and right plates are provided with a lower horizontal plate extending inwardly and horizontally therefrom. Each of lower horizontal plates comprises a curved portion extending upwardly from the outer edge thereof. The upper edge of the curved portion extends outwardly and horizontally to form an upper horizontal plate. The top, left, and right plates are united to form a housing body in such manners that upper horizontal plates of left and right plates are inserted into the receiving spaces of top plate and a molding tool is used to pack the upper and the lower horizontal plates and the basic strip portions. The housing body so made is devoid of sharp edges so as to prevent the user from being injured.
