Shower heads

A shower head comprising:

• a shell, wherein a connecting unit is located at an upper portion of the shell to connect to a water source, and a lower portion thereof has an opening, and an installation hole connecting to an inner space of the opening is disposed at one side of a periphery thereof;
• a positioning base, having a flat board, and a tube extending upwards from a center of the flat board, wherein a hanging base that has an elongated hole at a center thereof is sealedly disposed at a top portion of the tube, and a plurality of C-shaped hanging slots are circularly disposed around a periphery of the flat board;
• a plurality of water spraying heads, each being engaged with a corresponding one of the plurality of hanging slots via a recessed groove at an upper section of an outer periphery of each water spraying head, so as to evenly and circularly dispose the water spraying heads on the flat board of the positioning base, and a lower portion of each water spraying head is enlarged to form a water outlet portion defining a plurality of olive-shaped water channels along a peripheral surface of the water outlet portion;
• a plastic piece formed by injection molding with a through hole formed at a center thereof, and a plurality of through openings circumferentially formed around a periphery of the through hole, and a periphery of each through opening forms a downwardly protruding edge;
• a metal cover having a plurality of cover through holes formed therethrough, wherein a recessed receiving space is formed at a top surface of the metal cover, and a guiding rod protrudes upward from a center of the receiving space;
• and
• a handle set having a control unit, wherein a connecting rod eccentrically protrudes out from one end of the control unit, and the other end is provided with a nut to lock and engage with a movable handle,
• wherein the through hole of the plastic piece is provided for the guiding rod to pass therethrough, and each downwardly protruding edge of the plastic piece is plugged into a corresponding one of the metal cover through holes so as to secure the position of the plastic piece relative to the metal cover, so that the plastic piece is disposed in the receiving space of the metal cover, wherein the water spraying heads are installed on the flat board of the positioning base, and subsequently disposed into the shell with the positioning base through the opening, and wherein when the metal cover covers the opening, the guiding rod is inserted into the tube of the positioning base, and the through hole of the plastic piece is provided for the guiding rod to protrude therethrough, such that each of the water spraying heads is restricted and engaged within a corresponding one of the through openings of the plastic piece, and wherein the handle set is fastened through the nut and installed on the installation hole, and the connecting rod of the handle set is plugged into the elongated hole of the positioning base, so that the movable handle is operated to drive the connecting rod to eccentrically rotate, and the positioning base drives the water spraying heads to simultaneously move up and down, and the amount and style of water flows from the water channels are controlled according to each person's preference by changing relative positions between the water outlet portions and the through openings of the plastic piece.
