The subject innovation is related to a pristine number generator, combustion tube 14, outer tube 12 is the raw water inlet formed on one side of which the raw water is stored and, the combustion gas passes through the inside provided through said outer cylinder and said outer cylinder and the Vice 16 is internally installed in a longitudinal direction of the combustion tube to the outside of the combustion tube, but from the inside of the outer tube include Vice 18, provided along the longitudinal direction of the Vice outside the Vice; Longitudinal direction the other surface side of the length direction is blocked and the first Vice agent, and the connection is the raw water stored in the outer tube to flow into the interior of the Vice tube 28. The outer peripheral surface of the blind one side of the Vice and the outer tube a communication / connection, the Vice include raw water since the ancient times can be ancient to outflow outlet is formed over the inner longitudinal direction of the Vice and inside the longitudinal direction of the Vice is formed, ground water, river water, contaminated water, etc. to be able to efficiently get by the clean water by simple conversion can be purified by a number of ancient times.
