Patent ID: 7470107

Claim:
A turbine for a turbo blower comprising a plurality of guide vanes fitted between a circular base plate and a top plate, each of the guide vanes extend radically outward from close to the center of the base plate towards the outer edge of the base plate, and the turbine is disposed within an air hood; the air hood is provided with an air inlet and an air outlet, wherein the air inlet is located above a corresponding circular hole defined in a center portion of the top plate; the turbine for a turbo blower is characterized in that: the height of each of the guide vanes, commencing at a vane front end close to the center of the base plate, gradually decreases to a relatively lower point at the middle section of the guide vane; circumferential area swept out by rotation of a cross sectional height at any position between the vane front end and the relatively lower point is identical, and the height of each of the guide vanes, commencing at the relatively lower point, gradually increases to a vane rear end, thereby forming a curved shape.
