Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a brush-type shower head. 
     A variety of showers have conventionally been proposed. However, since a conventional shower head is so constructed that water is simply sprayed or sprinkled from a head surface, the water does not reach a user&#39;s scalp even if his or her hair is washed with shampoo. As a result, there is the possibility that surface activators, which are primary components of a shampoo may be left on the scalp. Accordingly, it is difficult to thoroughly wash hair in a short period of time with these devices. 
     The surface activators left on the scalp are condensed by a drier or the like, which is undesirable for the growth of the hair and for the scalp itself. Accordingly, there is a strong demand to provide a shower head which causes the hair and scalp to be washed while thoroughly removing shampoo components.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention will now be described with reference to the accompanying drawings which show preferred embodiments of the invention. 
     FIGS. 1 through 5 show a first embodiment in which each of projection members 4 is of the dual wall structure and a water discharge hole 7 and a water discharge window 9 are formed as water communication holes 3. FIG. 6 shows a second embodiment in which each of projection members 4 is of the dual wall structure and a water discharge hole 7 and a water discharge window 9 are formed as water communication holes 3. FIG. 7 shows a third embodiment in which two kinds of sleeves, i.e., a straight streamlined water sleeve 28 and a side streamlined water sleeve 30 are formed as projection members 4, and water discharge holes 7 and water discharge windows 9 are formed as water communication holes 3. FIGS. 8 through 11 show a fourth embodiment in which straight streamlined water sleeves 35 of a resin made block 37 and side streamlined water sleeve 38 of a resin made block 40 are formed as projection members 4, and water discharge holes 7 and water discharge windows 9 are formed as water communication holes 3. FIG. 12 shows a fifth embodiment in which a water communication hole 3 is formed at a tip end of each projection member 4 as a water discharge hole 7 without any water discharge window. 
     The first embodiment will now be described. The shower head of the first embodiment relates to a waist-level shower sink 11 as shown in FIG. 5. As best shown in FIG. 3, each projection member 4 is of the dual wall structure composed of a tapered inner sleeve 5 and a tapered outer sleeve 6. In the case where the water is fed from an inner passage 24 located on the upper side of FIG. 3 inside of the inner sleeve 5, the water is discharged through a space defined by an inner hole 5&#39; of the inner sleeve 5 and an inner hole 6&#39; of the outer sleeve 6 from a water discharge hole 7 at the tip end of the outer sleeve 6. Also, in the case where the water is fed from a space between the inner sleeve 5 and the outer sleeve 6 from an outer passage 25, the water is discharged through a cutaway portion 8 of the inner sleeve 5 and a water discharge window 9 of the outer sleeve 6. 
     It should be noted that the cutaway portions 8 of the inner sleeves 5 are formed so that the water is normally discharged radially inwardly toward a center of a head 2 as indicated by arrows in FIG. 1. 
     A switching-over action between the water discharge from the water discharge holes 7 of the outer sleeves 6 or the water discharge from the water discharge windows 9 is effected by using a knob 17 (FIG. 2). 
     FIG. 4 shows an example of a switching portion 10 driven by the knob 17 in accordance with the first embodiment. The water flowing through an introduction pipe 12 is temporarily stored in a chamber 13 and subsequently is discharged from a passage 18 through the inner passage 24, the inner hole 5&#39; of the respective inner sleeves 5, the inner hole 6&#39; of the respective outer sleeve 6, passages of the respective water discharge holes 7, or alternatively through a passage 19, the outer passage 25, the cutaway portions 8 of the respective inner sleeves 5 and the passages of the water discharge windows 9 by changing a position of a planar valve 14 in response to the movement of the knob 17. FIG. 4 shows the former flow system. 
     The structure of the switching portion 10 is not limited to that shown in FIG. 4 but it is possible to design the structure in any desired manner. Incidentally, in FIG. 2, reference numeral 1 denotes a grip portion. 
     With such a structure of the shower head in accordance with the first embodiment, it is possible to wash hair while massaging the scalp with the outer sleeves 6. At the same time, since the tip ends of the outer sleeves 6 are brought into contact with the scalp, the detergent components stuck to the scalp may be rinsed off in a short period of time with a small amount of water. 
     The shower head according to the first embodiment is particularly useful in washing long hair while raising it with the hands. 
     If the water is activated by using the electric stone proposed by the present applicants in, for example, Japanese Utility Model Unexamined Publication No. Hei 2-80336, Japanese Utility Model Unexamined Publication No. Hei 2-80450 and Japanese Utility Model Unexamined Publication No. Hei 2-96373 and is passed through the shower head in accordance with the first embodiment, it is possible to eliminate the shampoo components or reduce the amount of the shampoo due to the surface activation effect of the water. At the same time, since residual chlorine which is contained in the public water is electrically soluble with the water, there is less likelihood that the scalp and hair will be damaged. 
     If the activated water is thus used, it is possible to expect a public profit like enhancement of water quality by saving the amount of consumed water. 
     FIG. 6 shows a second embodiment in which the shape of the head is different from that of the first embodiment, and it is possible to change the direction of water supply as in the first embodiment. Reference numeral 20 denotes an inner disc having the inner sleeves 5, reference numeral 21 denotes an outer disc having the outer sleeves 6, reference numeral 22 denotes a screw, numeral 24 denotes an inner passage, numeral 25 denotes an outer passage, and numeral 26 denotes a spacer. 
     With such a structure in accordance with the second embodiment, it is possible to accomplish switching of the water supply directions by switching over the inner passage 24 and the outer passage 25 with a suitable means in the same manner as in the first embodiment. Additional structure is the same as that of the first embodiment. 
     FIG. 7 shows a third embodiment in which the head structure is the same as that of the second embodiment, and it is possible to switch over the water supply directions in the same manner as in the first embodiment. Numeral 27 denotes an inner disc having straight streamlined sleeves 28, numeral 29 denotes an outer disc having side streamlined sleeves 30, numeral 31 denotes a fastening screw, numeral 32 denotes a ring screw, numeral 33 denotes an inner passage, and numeral 34 denotes an outer passage. 
     With such a structure in accordance with the third embodiment, it is possible to accomplish switching of the water supply directions by switching the inner passage 33 and the outer passage 34 with a suitable means in the same manner as in the first embodiment. The other effect is the same as that of the first embodiment. 
     FIGS. 8, 9, 10 and 11 show a fourth embodiment in which a shape of a head 2 is the same as that of the second embodiment, and it is possible to switch over the water supply directions in the same manner as in the first embodiment. 
     In the fourth embodiment, the straight streamlined sleeves 35 are formed integrally with a base 36. A water communication hole 41 is formed in the base 36 formed of a resin block 37. Side streamlined sleeves 38 are projecting from an upper surface of base 39 formed of a resin block 40. Elongated projections 47 are provided on both edges of a lower surface of the base 39. A desired number of resin made blocks 40 each have a water passage 42 between the elongated projections 47. The desired numbers of the blocks 37 and 40 are fitted in an opening portion 43 of a central portion of the head 2 in a dividable manner. Numeral 44 denotes an inner passage, numeral 45 denotes an outer passage, numeral 46 denotes engagement retaining portion, and 48 denotes screws for fastening the dividable head 2. 
     With such an arrangement according to the fourth embodiment, it is possible to set the water supply directions at a desired direction by suitably combining the resin made blocks 37 and 40. Since the resin made blocks 37 and 40 are made integrally of resin, it is possible to mass produce the blocks. 
     It is possible to switch the water supply directions by switching over the inner passage 44 and the outer passage 45 with a suitable means in the same manner as in the first embodiment. The other effect is the same as that of the first embodiment. 
     FIG. 12 shows a fifth embodiment in which a shape of a head 2 is different from that of the first embodiment, and the water supply is carried out only from the water discharge holes 7 provided at the tip ends of the projection members 4. 
     As described above, according to the present invention, it is possible to wash the root portions of hair and head skin in a good condition. Accordingly, it is possible to provide a brush-type shower head which is excellent in health and aesthetics without any residual detergent on the scalp.
