Abstract
An outflow switch mechanism of a multi-function shower head includes an inner body, a button, a return spring, a valve shaft, a water division plate, a support press spring and a cover. The inner body has a valve chamber therein. A valve path for accommodating the valve shaft is between a seat and a chamber. The lower portion of the valve path is formed with an enlarged seat having longitudinal sliding grooves. The lower portion of the valve shaft extends into the enlarged seat. The bottom of a projecting rib formed between the sliding grooves has a gradient guide surface. The water division plate is formed with tooth blocks corresponding to the sliding grooves. The top of the tooth blocks has a gradient surface facing the gradient guide surface of the projecting rib. A magnet is fixed on the water division plate. A magnet is also provided on the cover.
