Claim Text:
1. A shower head, comprising a nozzle body and a handle; wherein the nozzle body comprises a hollow cylindrical member, a front cap, a connecting rod, a support disc, a container; and a back cap; the handle houses a channel inside from a bottom end to a top end; the top end of the handle is joined adjacent to a lateral side of a circumferential wall of the cylindrical member and water flowing through the channel into the cylindrical member becomes a swirl whose direction is identical to a tightening direction of twisting and joining the back cap to the cylindrical member; the cylindrical member comprises an inlet hole on the circumferential wall for connecting the channel of the handle, and a pair of blocking elements protruding from an inner wall of the cylindrical member where one blocking element is located between the inlet hole and the back cap, and the other blocking element is located oppositely; the front cap comprises a front side perforated with a plurality of outlet holes, a back side joined to the cylindrical member, and an axial element configured from a center toward the back side of the front cap; the axial element has a through channel having threads along an inner wall of the through channel; the connecting rod housed in the cylindrical member comprises a front end running through the front cap and joined to a rotating piece that is capable of being twisted clockwise or counter-clockwise, threads adjacent to the rotating piece and compatible with those on the inner wall of the through channel, and a back end configured with a cone-shaped locking element having a back side whose diameter is larger than that of the connecting rod, thereby forming a flange; the support disc housed in the cylindrical member comprises a front side facing the front cap slanted backward so as to prevent deformation, displacement, or damage to the support disc from the pressure exerted by the connecting rod, a flat back side facing the container, a first protrusion axially extended from a center of the front side, and a second protrusion axially extended backward from a center the back side, and a through channel runs through the first and second protrusions where the connecting rod runs through the through channel of the support disc; the support disc is displaced along with the movement of the connecting rod; and, when the support disc is moved backward, the support disc is stopped by the pair of blocking elements; the container is hollow, cylindrical in shape, and rotatably housed in the cylindrical member; the container comprises a front side facing the front cap, a back side facing the back cap, a plurality of fins slantwise configured along the circumference of the container so that the container is pushed to spin by the swirl of water, a locking notch on the front side of the container having an inner diameter slightly larger than an outer diameter of the second protrusion of the support disc so that the second protrusion is rotatably plugged into the locking notch, a third injection hole at the center of the back side of the container, a support tube surrounding the third injection hole axially extended from the back side of the container, and a release hole adjacent to the rim of the back side of the container where the cone-shaped locking element is embedded into the locking notch; inside the locking notch, a flange is configured from an inner wall of the locking notch so that the locking element is locked; the container is displaced along with the movement of the connecting rod; and the container is filled with one of liquid soap, essence, and lotion; and the back cap comprises a back side, a first injection hole at the center of the back side of the back cap, a front side facing the container, a guide tube surrounding the first injection hole axially extended from the front side of the back cap having a sealed front end, a second injection hole on the front end of the guide tube corresponding to and aligned with the third injection hole of the container, a ball and a spring housed in the guide tube where the ball, by the push of the spring, seals the first injection hole; a back end of the support tube of the container facing the back cap has an inner diameter slightly larger than an outer diameter of the guide tube; and the guide tube is rotatably plugged into the support tube of the container.
