Overhead shower head with backside switch

An overhead shower head, comprising:

• a water inlet joint;
• a main body extending in an axial direction, having a front and a rear, and having defined therein a through hole in the axial direction, which through hole accommodates the water inlet joint;
• a water diversion body that is disposed within the main body, that includes a first water chamber and a second water chamber independently disposed within the water diversion body, that has two ends, one end of the two ends being connected to the water inlet joint and another end of the two ends being disposed with a first outlet and a second outlet which have a height difference in the axial direction of the main body, the first water chamber and the first outlet forming a first function waterway, and the second water chamber and the second outlet forming a second function waterway;
• an outlet cover including a cover plate disposed with an inner ring outlet connected to the first outlet and an outer ring outlet connected to the second outlet, and a decorative cover;
• an accommodating chamber disposed in the front of the main body to accommodate the outlet cover;
• and
• a rear switch disposed on the rear of the main body at an eccentric position and including an external dial button, a first rotating shaft disposed at an eccentric position within the main body to which the external dial button is linked;
• and a sealing element linked to the external dial button so that, when the external dial button is moved, the sealing element moves in a horizontal direction within the water inlet joint to connect to at least one of the two outlets of the water diversion body to supply water to at least one of the first function waterway and the second function waterway,
• wherein the water diversion body is a water diversion ball, and wherein the cover plate of the outlet cover has a ball seat that is movably connected to and cooperates with the water diversion ball, the ball seat being swingable relative to the water diversion ball within the ball seat to move the cover plate with respect to a horizontal plane within the accommodating chamber.
