PURPOSE: A diffuser is provided to minimize deformation of an elastic tube by maintaining the original form of the elastic tube when blocking air supplied to the flow path groove of an inner support pipe. CONSTITUTION: A diffuser comprises an inner support pipe(100), an elastic tube(200), and a connector(300). The inner support pipe is formed in a hollow form inside. A flow path groove(110) is formed at the outer circumference of the inner support pipe in a longitudinal direction. A first through-hole(120) is formed at one side of the flow path groove. The elastic tube is inserted to the outside of the inner support pipe and seals both sides by being coupled at the outer circumference of the inner support pipe. The elastic tube has a plurality of micropores(210). The connector is coupled to be inserted into one side of the inner support pipe and is hollow inside. |
