     DETAILED DESCRIPTION OF THE INVENTION 
     The multi-function shower head 1 in the present invention, as shown in FIGS. 1, 3, 4 and 16, comprises a shower head body 4 and a grip 11 combined together, an extra bubble unit A, an extra sponge unit B, an extra massage unit C, an extra scrubbing unit D and an extra electric heat case 6 as the main components. 
     The grip 11, as best shown in FIG. 3, has three hollow tubular passages 21, 22 and 23 in its interior. A wire rope 31 is disposed in the passage 21, having its upper end fixed firmly at a shaft 321 of a swinging iron block 32 and its lower end connected with a shaft of a motor M, as shown in FIG. 5. The wire rope 31 can be rotated by the motor M, transmitting rotation to the shaft 321, which in turn rotates a gear 322 and accordingly a gear 323 engaging with the gear 322. As the gear 323 is fixed on a cylindrical shaft 33, on which the extra bubble unit A, or the extra massage unit B, etc. as shown in FIGS. 6-13 can be additionally assembled respectively so as to be rotated by the shaft 33. 
     The extra bubble unit A, as best shown in FIGS. 6 and 7, comprises filter nets A1 and A2 and a fan blade A3 and a square shaft A31 fitting in a square central hole 331 of the shaft 33 so as to be rotated by the motor M. Thus, when the bubble unit A assembled with the shower head 1 is put and rotated in the water in a bathtub, it can give rise to bubbles by striking the water mixed with soap solution or the like. 
     The extra sponge unit B as shown in FIGS. 8 and 9 comprises a sponge B1 and a square shaft B11 fitting in the hole 331 of the shaft 33 so that the sponge B1 can be rotated and scrub clean a human body with soap solution added on. 
     The extra massage unit C shown in FIGS. 10 and 11 comprises a massage semi-circular member C1 and a square shaft to fit in the hole 331 of the shaft 33 so as to be vibrated by the unbalanced movement of the swinging iron block 32 rotated by the wire rope 31. 
     The scrubbing unit D as shown in FIGS. 12 and 13 comprises a sponge or rubber D1 having a rough surface so as to scrub and clean a human body with water coming from passages D2, which are axially formed therethrough, when the scrubbing unit D is assembled with the shower head. Those four kinds of units can be selectably used in bathing. 
     The electric heat case 6 as shown in FIG. 17 comprises a storing chamber 61 for keeping soap solution therein. The storing chamber 61 has an outlet 612 and to communicate the tubular passage 22 to supply soap solution to the shower head body 4 by operating the push button switch 24. The push button switch 24 as shown in FIG. 2, comprises two valve openings 241, 242, two balls 2421, and two springs 2411 and 2412 urging said balls in the tubular passage 22, and a push button 243 set sidewise in the wall of the grip 11 and a spring 2431 under the button 243 to push a push block 2432. When the push button 243 is pressed to move the spring 2431 and the push block 2432 in order, the push block 2432 can move the balls 2421, 2422 to leave the valve openings 241 and 242 so that the soap solution can enter the upper section of the tubular passage 22 through the valve opening 241. On the contrary, if the button 243 is released to recover its original position, the valve openings 241 and 242 are automatically blocked by the balls 2412 and 2422 urged by the springs 2411 and 2422. 
     A shower head body 4 as shown in FIG. 14 is firmly mounted at the upper end of the grip 11, having a cylindrical gate 41, a lower gate disc 42, an upper gate disc 43, an outlet disc 44, and two anti-leak gaskets 45 and 46 combined together. The cylindrical gate 41 is fitted in a long groove 424 in the lower gate disc 42 and the upper gate disc 43, having three inlet holes 411, 412 and 413 formed irregularly not on a straight line. The lower gate disc 42 is provided with three concentric ring grooves 421, 422 and 423 and the upper gate disc 43 with three concentric ring grooves 431, 432 and 433. The outlet disc 44 is provided with a plurality of holes 441, 442 and 443 located along three concentric circles to correspond to the two groups of three concentric ring grooves 421, 422, 423, 431, 432, and 433, forming three--one of the outer, another of the middle and another of the inner--water passages 451, 452 and 453, as best shown in FIG. 3. After the outlet disc 44, the upper gate disc 43 and the lower gate disc 42 are orderly assembled together with screws, the water coming from the tubular passage 23 can be selected to flow through one of the three inlet holes 411, 412, and 413 in the gate 41, one of three round holes 4211, 4221, and 4231 in the three ring grooves 421, 422 and 423 and then finally through one of the holes 441, 442 and 443 in the outlet disc 44 as sprayed water in one of the three concentric circles a, b and c as shown in FIG. 4. In addition, for preventing the shower head body 4 from leaking, the anti-leak gaskets 45 and 46 are respectively pinched between the lower and the upper gate disc and the grip 11. 
     The shower head 1 can also be connected with a water hose 5 as shown in FIG. 16. The water hose 5, as best shown in FIG. 15, has three water passages 51, 52 and 53 which are respectively led to the hollow tubular passages 21, 22, 23 in the shower head 1. The electric heat case 6 is divided into three chambers. One of said chambers, as shown in FIGS. 16 and 17, is for installing the motor M therein, another is a storing chamber 61 for soap solution and another a heating chamber 62. The storing chamber 61 has a lid 611 for filling in soap solution and an outlet tube 612 connected to communicate the hollow tubular passage 22 the shower head 1 through the water passage 52 in the hose 5. The heating chamber 62 has an electric heater 621 fixed therein for heating and vaporizing the water therein, and the hot vapor produced therein is to be mixed; with air blown therein through a connecting tube 64 by a blower 63 connected with the motor M. Then the vapor mixed with air is to run out of a hole 623 in an upper horizontal wall 622 in an air chamber 65, from which the vapor mixed with air runs out through an outlet tube 651 to a place it is used as sauna vapor. The connecting tube 64 is provided with a one-way valve 641 at its end as shown in FIG. 18 to prevent the vapor from running back in the blower. In addition, a safety valve 66 is mounted at the upper wall of the air chamber 65 to let out an excessively high pressure vapor through a ball 661 therein to prevent explosion caused by too high pressure of the vapor therein. A filling tube 624 is provided at the side wall to fill water in the heating chamber 62. 
     A water inlet pipe 680 is provided to supply water to the shower head 1 from a suitable water source (not shown). The inlet end of the water inlet pipe 680 is divided into a first branch 681 connected to the electric heat case 6 to feed water into the heating chamber 62 and a second branch 683 by-passing the electric heat case 6 to communicate the water passage 53 in the hose 5. A water control valve assembly 68 is assembled in the inlet end of the pipe 680 with a valve 682 to control the water flow in the pipe 680 either into the first branch 681 or the second branch 683. 
     The wire rope 31 and the blower 63 are respectively connected with both ends of the shaft of the motor M in such a way that the motor rotates only the wire rope 31 when it rotates clockwise and rotates only the blower 63 when it rotates counterclockwise. This function of two different rotations of the motor M is attained by two needle bearings of one way rotation fixed at each end of the shaft. 
     A time switch 671 shown in FIG. 16 is provided at the lower section of the electric heat case 6 and marked as S in the diagram of a water supply control electric circuit illustrated in FIG. 19, functioning as an operator of an electro-magnetic valve Re installed at a side wall of the electric heat case 6. When the switch 671 is turned on, a plus signal is sent out of IC1 to actuate the electro-magnetic valve Re, which is then energized to begin to supply water to the shower head. In addition, the supplying time is also counted by IC1, and when the preset time ends, a minus signal is sent out of IC3 to IC5 to turn off the electromagnetic valve Re. Then the water is to be stopped. The time switch S can be freely used to supply water to the shower head for an adjustable preset period of time, saving manual operation of supplying water. 
     A time switch 672 is also provided at a lower side wall of the electric heat case 6 near the switch 671, for controlling the operation time of a heater tube 621 in the heating chamber 62. Thus, the water in said chamber 62 can be heated up for a preset period of time so as to be vaporized. The switch 672 is represented as S in the diagram of an electric circuit shown in FIG. 20. When the switch S is turned on, a plus signal is sent out of IC3 to IC1 to actuate a relay to energize the heater tube 621 and IC2 to start to count the heating time. When the preset time for heatoff the relay to cut off the heater tube 621. 
     Lastly, the shower head 1 and the electric heat case 6 are disposed near above a bathtub 7 as shown in FIG. 22. Then, the shower head 1 can be used as a faucet, to save the cost of a faucet. A shelf 8 as shown in FIG. 21 can be installed to put on attachable units such as the bubble unit, the sponge unit, etc. for convenient use.
