Abstract:
1. A shower having a shower area that is changeable with a variation in water pressure, comprising: a holding unit, through which a water channel is disposed; a spraying water unit, which is sealed with the holding unit, a middle cavity being formed between the holding unit and the spraying water unit and being connected with the water channel, the spraying water unit having at least a main spraying water group that is constantly connected with the middle cavity, and at least one branch spraying water group, each of the spraying water groups having a water inlet hole connected with the middle cavity and several water outlet holes connected with a corresponding water inlet hole; at least one movable unit having an assembly groove forming a through hole and being arranged mouth-down in the holding unit, a nut fixed on a top of the through hole and sealing a top opening thereof, a seal unit that is slidably connected with the through hole and sealing the through hole, and an elastic body disposed in the through hole and which is pressed between the nut and the seal unit and presses outwards against the seal unit, a number of the branch spraying water groups being equal with a number of the movable units, and being assembled together in a one to one correspondence; wherein when water pressure to the seal unit is less than an elastic force of the elastic body, the seal unit slides outwards to seal a respective water inlet hole; and when water pressure to the seal unit is more than the elastic force of the elastic body, the seal unit slides inwards to connect the respective water inlet hole with the middle cavity.
