Abstract
A shower having a shower area changed with variation of water pressure includes: a holding unit, in which a water channel is designed and a feed-water valve is added on the top of the water channel; a spraying water unit, which is sealed with the holding unit, comprising at least two spraying water groups that are a main spraying water group and at least one branch spraying water group; and at least one movable unit, whose number is equal with the number of branch spraying water groups, assembled with the branch spraying water groups in one to one correspondence. In order to change the shower area, we could regulate the opening and closing of the feed-water valve to control water pressure.
