ABSTRACT:
A sanitary air jet device [1000] is operated by a user blowing air into its first stage inlet [1111] of a mouthpiece [1110]. The air stream causes a first stage turbine [1130] to rotate and spin a shaft [1205]. The shaft passes through a separator wall [1140]. A second stage turbine [1230] is connected to the shaft [1205] on the other side of the separator wall [1140] in a second stage chamber [1201]. The shaft [1205] causes second stage turbine [1230] to spin and draw air in through a number of second stage inlets [1211] in the second stage chamber [1201]. The second stage turbine [1230] blows the clean air out of a second stage exhaust [1221]. The second stage chamber [1201] is separated from the first stage chamber [1101] such that it does not receive the air blown in by the user. Therefore, one may blow out candles on a cake with clean air and no longer spray saliva droplets and microbes on the cake.
