<P>PROBLEM TO BE SOLVED: To provide a water ejection apparatus which is capable of affecting useful action to human body. <P>SOLUTION: At the water ejection part 12 of the shower head 10, a swirling chamber 16 to swirl water introduced so as to set the course in the tangential direction from a water introduction channel 15 along the peripheral wall and to transfer the swirled water to the center direction of swirling is formed. At the downstream of the swirling chamber 16, a throttling part 17 to eject the water introduced with a swirled state from the swirling chamber 16 is formed. At the downstream side of the throttling part 17, a mixing chamber 18 to swirl the water introduced in a swirled state from the throttling part 17 with bigger swirling radius and to eject the water outside through the water discharge aperture 14a is formed. Further, a first air introduction part channel 19 and a second air introduction channel 20 for releasing the air introduced from the outside from the throttling part 17 and the opening on the inner periphery of the mixing chamber 18 into the throttling part 17 and the mixing chamber 18 are formed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
