Abstract
A cigarette temperature detection device including multiple cylindrical convex lenses is provided, wherein each of the cylindrical convex lenses has a thicker central wall between two thinner end walls formed by rotating a parallel line at a predetermined distance around a long axis of an elliptical-like section resulting from cutting the circular convex lens by a plane perpendicular to a centerline. The disclosed cigarette temperature detection device allows accurate and reliable detection of a temperature of an entire circumferential surface of a cigarette on site.
