Abstract

The hand held shower apparatus of this invention includes a shower body having a hollow handle connectable at one end to a source of water and a shower head, water regulating means for regulating the supplied water into two different water streams, one with a showering effect and the other with a massaging effect, and a cap member having a perforated bottom surface with two groups of holes for the two water streams. The hollow handle is constructed in such a way that it can be extended by pulling it away from the shower head. The shower apparatus also has a shower utensil, such as a shower brush, connected with the cap member in such a way that the shower utensil moves up or down when rotated clockwise or counterclockwise with respect to the cap member. Construction of the shower apparatus has been made simple so that it can be assembled or disassembled with ease. Other embodiments of the shower utensil are also presented.

Claims

1. A hand-held shower apparatus comprising:

a shower body having a hollow handle adaptable to connect to a source a water and a shower head having an inner cylindrical wall which forms an inner cavity communicated via the hollow handle to the source of water;

water regulating means having an axial cylindrical wall defining an axial hollow portion and fitted inside the inner cavity and rotatably mounted to the shower head and capable of being controlled externally of the shower head, the axial cylindrical wall having an opening communicated with the axial hollow portion and being disposed in such a manner that the rotation of the water regulating means can establish the communication of the opening with the source of water, and a groove similarly disposed in such a manner that the rotation of the water regulating means can establish the communication of the groove with the source of water; and

a cap member, being detachably and sealingly engaged to the shower head, having an outer cylindrical wall, a perforated bottom surface joined to the lower periphery of said outer cylindrical wall, and an inner partition wall forming a first chamber and a second chamber with the perforated bottom surface such that when said cap member is engaged to the shower head, water passing through the opening of the water regulating means would be received by the first chamber, and water passing through the groove would be received by the second chamber, and

a ring shaped base with a plurality of spiral grooves in its annular inner surface and a plurality of brush bristles affixed to the base, and said cap member having a plurality of spirally extending protrusions on the outer cylindrical wall for matingly engaging the spiral grooves of the base.

2. A hand held shower apparatus as claimed in claim 1 wherein the hollow handle of said shower body comprises a water pipe one end of which is connected to said water source, and a handle casing being telescopically connected with said water pipe, thereby making the hollow handle extendible by pulling the handle casing away from the shower head.

3. A hand held shower apparatus as claimed in claim 2, wherein said cap member includes an annular flange member extending outwardly from the top edge of said outer cylindrical wall, and further comprising a casing capable of being sleeved over said cap member and having an annular wall for surrounding said base, and a flange member inwardly and radially extending from the upper edge of said annular wall so as to rest on said annular flange member.

4. A hand held shower apparatus as claimed in claim 3, wherein the casing comprises a plurality of axial key member extending along its inner surface and the base has a plurality of key ways equal in number to the axial key members, the cooperation of said axial key members and said key ways hindering the relative rotation of the casing to the base.

5. A hand-held shower apparatus comprising:

a shower body having a hollow handle adaptable to connect to a source of water and a shower head having an inner cylindrical wall which forms an inner cavity communicated via the hollow handle to the source of water;

water regulating means having an axial cylindrical wall defining an axial hollow portion and fitted inside the inner cavity and rotatably mounted to the shower head, and capable of being controlled externally of the shower head, the axial cylindrical wall having an opening communicated with the axial hollow portion and being disposed in such a manner that the rotation of the water regulating means can establish the communication of the opening with the source of water, and a groove similarly disposed in such a manner that the rotation of the water regulating means can establish the communication of the groove with the source of water; and

a cap member, being detachably and sealingly engaged to the shower head, having an outer cylindrical wall, a perforated bottom surface joined to the lower periphery of said outer cylindrical wall, and an inner partition wall forming a first chamber and a second chamber with the perforated bottom surface such that when said cap member is engaged to the shower head, water passing through the opening of the water regulating means would be received by the first chamber, and water passing through the groove would be received by the second chamber, and

a ring shaped base with a plurality of spiral grooves in its annular inner surface and a plurality of hemispherical protrusions affixed to the base for massage purposes, and said cap member having a plurality of spirally extending protrusions on the outer cylindrical wall for matingly engaging the spiral grooves of the base.

6. A hand held shower apparatus as claimed in claim 5, wherein said cap member includes an annular flange member extending outwardly from the top edge of said outer cylindrical wall, and further comprising a casing capable of being sleeved over said cap member and having an annular wall for surrounding said base, and a flange member inwardly and radially extending from the upper edge of said annular wall so as to rest on said annular flange member.

7. A hand held shower apparatus as claimed in claim 6, wherein the casing comprises a plurality of axial key members extending along its inner surface and the base has a plurality of key ways equal in number to the axial key members, the cooperation of said axial key members and said key ways hindering the relative rotation of the casing to the base.

8. A hand-held shower apparatus comprising:

a shower body having a hollow handle adaptable to connect to a source of water and a shower head having an inner cylindrical wall which forms an inner cavity communicated via the hollow handle to the source of water;

water regulating means having an axial cylindrical wall defining an axial hollow portion and fitted inside the inner cavity and rotatably mounted to the shower head and capable of being controlled externally of the shower head, the axial cylindrical wall having an opening communicated with the axial hollow portion and being disposed in such a manner that the rotation of the water regulating means can establish the communication of the opening with the source of water, and a groove similarly disposed in such a manner that the rotation of the water regulating means can establish the communication of the groove with the source of water; and

a cap member, being detachably and sealingly engaged to the shower head, having an outer cylindrical wall, a perforated bottom surface joined to the lower periphery of said outer cylindrical wall, and an inner partition wall forming a first chamber and a second chamber with the perforated bottom surface such that when said cap member is engaged to the shower head, water passing through the opening of the water regulating means would be received by the first chamber, and water passing through the groove would be received by the second chamber, and

a ring shaped base with a plurality of spiral grooves in its annular inner surface and a plurality of comb teeth affixed to the base, and said cap member having a plurality of spirally extending protrusions on the outer cylindrical wall for matingly engaging the spiral grooves of the base and

said cap member includes an annular flange member extending outwardly from the top edge of said outer cylindrical wall, and further comprising a casing capable of being sleeved over said cap member and having an annular wall for surrounding said base, and a flange member inwardly and radially extending from the upper edge of said annular wall so as to rest on said annular flange member.

9. A hand held shower apparatus as claimed in claim 8, wherein the casing comprises a plurality of axial key members extending along its inner surface and the base has a plurality of key ways equal in number to the axial key members, the cooperation of said axial key members and said key ways hindering the relative rotation of the casing to the base.
