Detailed description



[0036] A shower which can produce different sprays from same water outflow port, please refer to Fig. 1 to Fig. 15, comprises a fixing assembly 1, a movable part 2, an operating member 3 and a driving mechanism 4. The fixing assembly 1 is provided with a water outlet chamber 11 connecting to the water supply.

[0037] The fixing assembly 1 is provided with a cover assembly 12, which is provided with a plurality of water outflow ports 13 fluidly connecting the water outlet chamber 11. The movable part 2 is movably disposed in the fixing assembly 1 and comprises a movable plate 21 and a plurality of convex parts 22 protruding from the bottom surface of the movable plate 21. The driving mechanism 4 is connected to the movable part 2 in a transmission way and can drive the movable part 2 to do cyclic repetitive motion. The cyclic repetitive motion is that the middle line of the movable part 2 (such as its own axis) moves circularly around its eccentric position. The operating member 3 and the movable part 2 are connected in a transmission way, and the operating member 3 can drive the movable part 2 to move among the three control positions. The distance between the movable part 2 in different control positions and the cover assembly 12 are difference. When the movable part 2 moves to at least one of three control positions, the convex parts 22 are inserted into the water outflow ports 13. When the movable part 2 does cyclic repetitive motion s, the convex parts 22 rotate relative to the center line (such as the axis) of the water outflow ports 13. Different spray patterns will be produced when the movable part 2 is in different control positions. In this specific embodiment, three control positions are illustrated as an example, but not as limited as this. Two or more than three control positions can be used as required.
