Spiral of air flow

摘要

The invention consists of a Cuban structure (5) which supports an inverted bottle (1) by a bracket (6),There is a valve (2) with a drip irrigation device at the outlet,A spout (3) is centered on one of its sides, so that when the user exhales through the air, it transmits the exhaled speed to the fluid. When the liquid of this color lands on the portable and exchangeable recording device (4), a distance is determined to represent the speed of spiral air. There, the sides of the Cuban structure (5) are covered with transparent material to avoid distortion when measuring the speed and volume flow of spiral air
