[0008] In the double function shower head, the inner tube is fixed in the ball joint and has a gap between the outer side of the inner tube and the inner wall of the ball joint, so that the ball joint is divided into two passages, and the two passages enter the shower head body from the lower end of the water inlet connector after passing through the water inlet connector. During use, one of the two water paths enters the inner tube from the upper end of the inner tube, flows out of the lower end of the water inlet connector to the first water outlet passage of the shower head body after passing through the water outlet one and the inner hole of the convex shoulder, and performs water discharge, in which process, air enters the water inlet connector from the air inlet provided on the side of the water inlet connector and mixes with the water flow in the water inlet connector, so that the air mixing function of rain shower water discharge is realized, the comfort of shower is improved, and water is saved. The other of the two water paths flows into the gap between the ball joint and the inner tube from the upper end of the ball joint, flows into the inner hole of the water inlet connector above the convex shoulder through the water outlet two on the side of the lower end of the ball joint, and is prevented from flowing to the inner hole of the convex shoulder communicating with the water outlet one due to the separation of the sealing element, and flows downward to the outer side of the lower end of the water inlet connector through the water passing hole two, and then is discharged from the second water outlet passage of the shower head body.
