Abstract
A multi-spray shower head comprising a mist spray. When used with hot water this fine spray becomes steam. To prevent the user from scalding him- or herself immediately after using the mist spray with such hot water, the shower head includes a water operated safety pin assembly (60) which locks the shower head on the mist spray mode until the water pressure is reduced below a predetermined level. The mist spray is formed by passing water through mist channels (112) which have mist pins (114) which form spiralling water paths whereby water emerges from small diameter mist apertures (28) as a fine spray.
