mounting grooves

11a, 11b, 11c extend from the water outlet end to the water inlet end of the connecting base 11. Three

mounting groove

11a, 11b, 11c are along circumferencial direction evenly distributed to the diapire of each mounting groove respectively with the exit end local intercommunication of inlet channel 11d, wherein be equipped with thrust spring 7 and adjusting ball 6 in second mounting groove 11b and the third mounting groove 11c, thrust spring 7's one end is connected with the diapire that corresponds the mounting groove, thrust spring 7's the other end with correspond adjusting ball 6 and be connected, adjusting ball 6 and the lateral wall sealing fit of mounting groove.

The open end of the rotary cover body 1 is sleeved on the outer wall of the connecting seat 11 and is rotatably connected with the connecting seat 11, and the closed end of the rotary cover body 1 is provided with three nozzle through holes with different shapes, namely a first nozzle through hole 1a, a second nozzle through hole 1b and a third nozzle through hole 1 c. The inlet ends of the three nozzle through holes are communicated with the open ends of the three mounting grooves in a one-to-one correspondence manner. And a sealing ring 5 is arranged between the inlet end of each nozzle through hole and the connector respectively.

The utility model discloses a shower nozzle can also include: a U-shaped lock pin 2, so as to realize the reinforced connection of the connecting seat 11 and the rotary cover body 1 through the U-shaped lock pin 2. In addition, a first O-shaped ring 8 is arranged between the outer wall of the connecting seat 11 and the rotary cover body 1, and a second O-shaped ring 12 is arranged between the outer wall of the connecting seat 11 and an external water pipe.
