Claim:
A sanitary air jet [ 1000 ] for creating a stream of clean air to blow onto an object from a stream of air blown by the mouth of a user comprising: a) a first stage turbine [ 1130 ] having angled fins [ 1131 ] designed to rotate when it receives a stream of air passing through it; b) a first stage inlet [ 1111 ] for receiving a stream of air from said user and directing it through the first stage turbine [ 1130 ]; c) a first stage exhaust [ 1120 ] for exhausting the user's air stream; d) at least one second stage inlet [ 1211 ] for drawing clean air into the sanitary air jet [ 1000 ]; e) a second stage exhaust [ 1221 ] allowing a stream of clean air to flow out of the sanitary air jet [ 1000 ]; f) a second stage turbine [ 1230 ] coupled to, and driven by the first stage turbine [ 1130 ] causing the second stage turbine [ 1230 ] to draw in clean air through the second stage inlets [ 1211 ] and blow the clean air out of the second stage exhaust [ 1221 ] as a clean air stream when rotated.
