DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown inFIG. 3. In the first embodiment of the present invention, the shower nozzle device1includes a shower nozzle body10and a sucking disc20. The sucking disc20includes a gland202and a pull rod204. The shower nozzle device1is assembled by passing a bolt30at the same time through several holes, which are separately the holes1011on the pair of the protrusions101, the first through hole2026on the hollow cylinder2022extended from the center of the gland202and the second through hole2043on the rod body2042extended from the center of the pull rod204. In the present invention, the main technical characteristic is able to move the shower nozzle body10forwards and backwards so that the shower nozzle device1can be attached to the adsorbed surface40or detached from the adsorbed surface40.

The purpose of using the shower nozzle body10and the basic principle of attaching the sucking disc20to the adsorbed surface40are understood by the person having ordinary knowledge in the art. Therefore, as far as the characteristic of combining the shower nozzle body10and the sucking disc20and the effectiveness produced are concerned it is illustrated in the following description of the present invention. In addition, the drawings in the following description are not drawn by the actual size, and the diagrams are only to show some characteristics relative to the present invention.

As shown inFIG. 1A to 1C,2,3, and4. According to the first embodiment of the present invention, the shower nozzle device1includes a shower nozzle body10and a sucking disc20. The shower nozzle body10includes a pair of the protrusions101disposed on a surface100reversely opposite to blowholes (not shown) and each protrusion.101includes a hole1011. The sucking disc20includes a gland202and a pull rod204, and the gland202includes a circular cover2021and a hollow cylinder2022extended from the center of the circular cover2021. The hollow cylinder2022includes the first through hole2026. The pull rod204includes a plane2041and a rod body2042extended from center of the plane2041. The rod body2042includes a second through holes2043. When the assembly of the gland202and the pull rod204is finished, the first through hole2026on the hollow cylinder2022of the gland202is aligned to the second through hole2043on the rod body2042of the pull rod204. The hollow cylinder2022of the gland202is further disposed between the pair of the protrusions101of the shower nozzle body10so that the first through hole2026of the hollow cylinder2022is aligned to the hole1011of the pair of the protrusions101. Thereafter, the shower nozzle device I is able to assembled by passing the bolt30at the same time through the hole1011on the pair of the protrusions101of the shower nozzle body10, the first through hole2026on the hollow cylinder2022of the gland202and the second through hole2043on the rod body2042of the pull rod204.

As shown inFIG. 1A to 1DandFIG. 3, the pair of the protrusions101on the backside of the shower nozzle body10is mainly used to assemble the sucking disc20and the bolt30together. The pair of the protrusions101is a concave-shaped structure producing a space1012, by which two sides are separated. Each side has a hole1011that the bolt30can be passed through. The shower nozzle device1is assembled by putting the hollow cylinder2022and the rod body2042into the space1012of the concave-shape structure, then the bolt30is mutually passed through the first through hole2026on the hollow cylinder2022, the second through hole2043on the rod body2042and the holes1011at two sides of the concave-shape structure. The bolt30is a strip-type cylinder to be the medium of the assembly to the shower nozzle body10and the sucking disc20. Especially, as shown inFIG. 3of the present embodiment, the radial distance from the top pair of the protrusions101outside to the hole1011is different. The radial distance from the top pair of the protrusions101outside to the hole1011is smaller than the radial distance from the bottom pair of the protrusions101outside to the hole1011.

As shown inFIG. 2. The gland202of the sucking disc20includes the circular cover2021which the internal part is hollow to produce a space2027, and the internal surface2020in the circular cover2021has a circular protrusion2024. A protrusion2023disposed in the radial direction of the circular cover2021is located in the internal surface2020between an open end20211of the circular cover2021and an open end20241of the circular protrusion2024. The protrusion2023is a semicircular cylindrical shape and has a thickness LI in the axial direction of the circular cover2021. The purpose of disposing the protrusion2023is to separate the gland202and the pull rod204when the user would like to detach the sucking disc20from the adsorbed surface40. The circular protrusion2024has a thickness L2in the radial direction of the circular cover2021. The thickness L2is in action to cause the plane2041of the pull rod204to be against the open end20241of the circular protrusion2024when the gland202and the pull rod204are disposed together. In addition, as shown inFIG. 3, the plane2041of the pull rod204includes a first adsorptive board2044and a second adsorptive board2045. The better configuration regarding to the rod body2042of the pull rod204or the hollow cylinder2022of the circular cover2021prefers to be a hexagonal cylinder. The front side of the rod body2042has a second through hole2043to pass the bolt30through so as to assemble the shower nozzle body10, the gland202, the pull rod204and the bolt30together. The back side of the rod body2042is connected to the first adsorptive board2044and the second adsorptive board2045, and both discs have the same size and stacked each other. The second adsorptive board2045is used to be attached to the adsorbed surface40where the sucking disc20is disposed. The material of the second adsorptive board2045is softer than the first adsorptive board2044so as to be attached to the adsorbed surface40easier.

As shown inFIG. 5, according to the first embodiment of the present invention, it is a flow chart illustrating a using method of the shower nozzle device1, and attaching a shower nozzle device1to the adsorbed surface40and detaching it from the adsorbed surface40. First, approaching the sucking disc20to an adsorbed surface40and turning the shower nozzle body10to move backwards so that the second adsorptive board2045on the plane2041of the sucking disc20is able to be attached to the adsorbed surface40; and then moving the shower nozzle body10forwards to turn the pair of the protrusions101and pressuring the pair of the protrusions101into the surface of the gland202by the gravity of the shower nozzle body10.

Secondly, the shower nozzle body10is completely drooping and pressuring the pair of the protrusions101into the surface of the gland202by the gravity of the shower nozzle body10. Based on the reason that the distance from the top pair of the protrusions101outside to the hole1011is smaller than the distance from the bottom pair of the protrusions101outside to the hole1011, the rotation of the pair of the protrusions101can drive to move the pull rod204and the plane2041forwards by pressuring the gland202. Therefore, the air between the second adsorptive board2045and the adsorbed surface40is excluded to enclose a vacuum and the first adsorptive board2044is firmly made against the open end20241of the circular protrusion2024to make the shower nozzle device1attached firmly to the adsorbed surface40. Thirdly, for the purpose of detaching the shower nozzle device1from the adsorbed surface40, turning the shower nozzle body10and moving the shower nozzle body10backwards to lift the shower nozzle body10to form a gap between the protrusion2023within the gland202and the plane2041of the pull rod204. Thus, the vacuum is broken out when the air gets into the internal space2027of the gland202, and that the distance from the top pair of the protrusions101outside to the hole1011is smaller than the distance from the bottom pair of the protrusions101outside to the hole, the rotation of the pair of the protrusions101releases the pressure from the pair of the protrusions101to the gland202so as to drive the gland202to move and to move the pull rod204and the plane2041backwards.

As shown inFIG. 6, according to the second embodiment of the present invention, it is a using method of the shower nozzle device1′. The basic structure of the shower nozzle device1′ in the second embodiment is the same as the first embodiment describing the shower nozzle device I composed of a shower nozzle body10and a sucking disc20. The shower nozzle body10includes a pair of the protrusions101disposed on a surface100reversely opposite to blowholes (not shown) and each protrusion101includes a hole1011. The sucking disc20includes a gland202and a pull rod204, and the gland202includes a circular cover2021and a hollow cylinder2022extended from the center of the circular cover2021. The hollow cylinder2022includes the first through hole2026. The pull rod204includes a plane2041and a rod body2042extended from the center of the plane2041. The rod body2042is a hexagonal cylinder and has a second through hole2043in the front side of the rod body2042for passing the bolt30through to assemble the shower nozzle body10, the gland202, the pull rod204and the bolt30together. The gland202of the sucking disc20has a circular protrusion2024in the internal surface2020of circular cover2021. A protrusion2023disposed in the radial direction of the circular cover2021is located in the internal surface2020between an open end20211of the circular cover2021and an open end20241of the circular protrusion2024. The difference of the present embodiment from the first embodiment is in the following of the description, the back side of the rod body2042is connected to the plane2041, inclusive of the first adsorptive board2044′ and the second adsorptive board2045′. Both discs are different sizes and the area of the second adsorptive board2045′ is larger than the first adsorptive board2044′. The second adsorptive board2045′ is used to be attached to the adsorbed surface40where the sucking disc20is disposed. The material of the second adsorptive board2045′ is softer than the first adsorptive board2044′ so as to be attached to the adsorbed surface40easier.
