Detailed Description

Fig. 1, fig. 2, and fig. 3 show a first embodiment of the present invention. The valve body 1 is provided with a first sealing ring 3 and a second sealing ring 5, the sealing rings are elastic, and the outer diameter of the second sealing ring 5 is larger than that of the first sealing ring 3 in the installation state. The adjusting ring 4 is sleeved on the valve body 1, a small hole section 4-2 of the adjusting ring 4 and the sealing ring I3 form sealing, sealing damping can reliably support the adjusting ring, and the section 4-4 is arranged between the air inlet 1-1 and the sealing ring II 5. The nozzle 2 is fixed in the valve body 1 through threads, and the lower part of the valve body 1 is provided with a ball head suitable for being connected with a top shower head.

As shown in figure 1, water with certain pressure is accelerated by a nozzle 2 to form negative pressure in the area of a nozzle water outlet, and air outside the valve body is sucked into the valve body through a gap 6, a gap 7, a gap 8 and an air inlet 1-1, is mixed with the water and is sprayed out from the lower part of the valve body. The adjusting ring 4 is twisted left and right by pulling down or slightly bringing down force, so that the air suction amount can be reduced and the noise can be controlled by moving down the adjusting ring. When the adjusting ring is moved downwards to the position shown in figure 2 by slight force to make the section 4-4 close to the second sealing ring 5, the air inlet is blocked.
