초록 ▼

The improved showerhead disclosed herein includes at least two, and preferably four, separate spray nozzles and is constructed so as to permit users to select the particular spray nozzle through which water is to be discharged. The showerhead may be mounted on the end of a conventional shower arm extending from a wall or may be held in the user\s hand and connected with a source of water by a flexible conduit. The showerhead comprises a housing having disc member and dial assembly mounted thereon. The dial assembly includes the spray nozzles, and the selection of a particular spray nozzle is achieved by manually rotating the dial assembly, with respect to the disc member and housing, about its central axis. A novel “butterfly”seal is disposed between the disc member and the dial assembly. A latch is mounted on the housing and cooperates with the dial assembly to retain the dial assembly in its proper position with respect to the disc member. The latch also serves as an indicator to enable the user of the showerhead to know where to position the dial assembly, with respect to the disc member and housing, so that water will be sprayed through a particular spray nozzle. The structure of one of the spray nozzles, when utilized in cooperation with the disc member, provides a pulsating, invigorating spray.

대표청구항 ▼

An improved showerhead having at least one spray nozzle and being adapted to be connected with a source of water under pressure, the improved showerhead comprising: a housing including means which defines a conduit through which water may flow and having a front end and a rear end which may be connected with the source of water under pressure and which communicates with the conduit means so that water from the source may flow through the conduit means from its rear end to its front end; a disc member having a front surface and a rear surface and being connected with the front end of the housing so that the rear surface extends across and closes the front end of the housing and so that the water flowing in the conduit means communicates with the rear surface of the disc member, the disc member having a first circular aperture disposed therein and extending therethrough between the front surface and the rear surface; a nozzle assembly including a front end wall and a rear end wall and being connected with the disc member so that the rear end wall of the nozzle assembly is positioned adjacent to the front surface of the disc member, with the front end wall of the nozzle assembly including a spray nozzle which is adapted to emit a pulsating spray of water; and with the rear end wall of the nozzle assembly having a circular nozzle aperture which has the same diameter as the first aperture and which is disposed so that its central axis is coaxial with the central axis of the first aperture and so that the nozzle aperture and the first aperture define an initial, continuous flow path for the water; the spray nozzle having an outer conical wall, an inner conical wall and a discharge orifice wall which, together the rear end wall of the nozzle assembly, define a turbulence cavity, with the discharge orifice wall having a discharge orifice therein through which the water being sprayed is emitted, with the central axes of the outer conical wall, the inner conical wall and the discharge orifice being coaxial and being offset from but parallel tO the central axis of the nozzle aperture and with the plane of the discharge orifice wall being transverse to the central axis of the outer conical wall, the inner conical wall and the discharge orifice; the outer conical wall having its first, larger diameter end disposed adjacent to the rear end wall of the nozzle assembly and its second smaller diameter end disposed adjacent to the front end wall of the nozzle assembly; the inner conical wall being disposed generally within the outer conical wall and having its first, larger diameter end disposed adjacent to and connected with the second, smaller diameter end of the outer conical wall and its second, smaller diameter disposed within the turbulence cavity and between the first and second ends of the outer conical wall; the discharge orifice wall extending across, and except for the discharge orifice therein, closing the second, smaller diameter end of the inner conical wall.
