Abstract
A water separation structure of a shower head includes a cover unit, a cover seal seat and a main body seal seat. The cover unit has three water outlets. Three water passages and a shift water passage are formed between the cover seal seat and the cover unit. The cover seal seat has five through holes. The main body seal seat has a water inlet and a blind hole which are spaced and located corresponding to the five through holes. The water inlet comprises a seal ring therein. The blind hole comprises a seal pad therein. The water inlet communicates with one of the five through holes by means of rotation to open the relative water passage. The blind hole is to block the other through holes and close the other water passages. The seal ring and the seal pad are against the cover seal seat.
