## Abstract

An elliptical and funnel-shaped jet nozzle structure includes a plurality of elliptical tapered diversion channels, a plurality of elliptical jet nozzles and a conveyer belt. A wall thickness of each of the elliptical tapered diversion channels is 1-5 mm. A wall thickness of each of the elliptical jet nozzles is 1-5 mm. A thickness of the conveyer belt is 1-5 mm. The elliptical tapered diversion channel is a hollow elliptical truncated cone and it includes an upper opening and a lower opening. The upper opening of the elliptical tapered diversion channel is connected to an elliptical opening, and the lower opening of the elliptical tapered diversion channel is connected to an inlet of the elliptical jet nozzle. The elliptical jet nozzle is a hollow elliptical cylinder.
