  • Patent number: 11761182
    Abstract: A showerhead assembly is provided which includes a handheld showerhead removably connected to a stationary showerhead through ball joint connection. The handheld showerhead includes an elongate handle having an upper housing with a cavity, and a front face including one or more nozzles for spraying water. The stationary showerhead has a traditional showerhead construction, with the exception that it further comprises a ball which engages with the handheld showerhead's cavity so as to allow rotatable and secure attachment of the handheld showerhead to the stationary showerhead. The ball may include a preliminary alignment chamber which houses a locking chamber, and the cavity may include a tension pin which engages with both these chambers so as to provide further support for installation of the handheld showerhead to the stationary showerhead. In addition, a spring-button tab mechanism may be utilized for managing the engagement and disengagement of the ball with the cavity.

  • Patent number: 11697127
    Abstract: An improved showerhead assembly is provided for use with handheld showerheads. The handheld showerhead includes an elongate handle and a showerhead face including one or more nozzles for spraying water. In addition, the showerhead assembly includes a hollow mount for affixing to the male threaded pipe found in a shower stall. The mount includes a “C” shaped receptacle for holding the handheld shower assembly, an inlet for receiving water, as well as an outlet for expelling water to a flexible hose, which in turn is connected to the handheld showerhead.

  • Patent number: 11660623
    Abstract: A showerhead assembly is provided which includes a conduit, a gear train and oscillating nozzle chamber. The gear train includes a propeller, toothed pinion, and large toothed gear. Water flows from the conduit into an internal chamber within the showerhead housing. Specifically, water enters the propeller thereby causing it to rotate, the rotation of which causes the pinion to rotate, and consequently, the large gear to revolve. Additionally, a pin seated on the large gear engages with the pin slot located on the nozzle chamber and causes the chamber to pivot, thereby restricting chamber movement as the pin oscillates with rotation of the large gear. Further, the chamber's horizontal movement is hindered by two shoulder arms. As water exits the large gear, it travels through the left shoulder arm's central channel and into the oscillating chamber, whereby it expels through the nozzle outlet in a reciprocating spray pattern.

  • Patent number: 11376614
    Abstract: A showerhead assembly is provided which includes an outer housing and inner housing. The inner housing includes a support disk and gear housing disk having two diverter arms and a gear train. The gear train includes a propeller, a coaxial pinion, and a large gear. The outer housing includes the base and a faceplate having nozzle systems connecting to complementary orifices. Water enters the internal housing via a channel where it is further diverted by the diverter arms so as to impinge on the gear train's propeller, causing the gear train's individual components to rotate. Upon the rotation of the large gear, the large gear's slot aligns with a selected orifice whereby water travels through and enters a corresponding nozzle system. This sequence continues, causing water to sequentially spray from individual nozzles in systematic intervals so as to create a strobe-like spray pattern.

  • Publication number: 20220048048
    Abstract: A water spraying assembly is provided which includes a central conduit, an impeller, and a mist nozzle having a tapered chamber that decreases in cross-sectional area as it narrows into a nozzle outlet sufficiently small so as to reduce the flowing water's pressure as it is transported down the chamber. The impeller includes blades which form channels for receiving water from the central conduit. Further, these channels produce a vortex, rotating the passing water stream. The impeller is directly adjacent to, upstream and in fluid connection with the entrance of the tapered chamber which tapers inwardly until it reaches its smallest measurement at the nozzle outlet. Consequently, the swirling water and the tapered chamber create a low-pressure environment, thereby increasing the water's velocity and force. Due to the high velocity and the outlet's small opening, water is ejected from the outlet as small droplets in a fine mist spray pattern.

  • Publication number: 20210187520
    Abstract: A water spraying assembly is provided which includes a fluid conduit, a vortex chamber and a nozzle. The nozzle has a constricted section which forms a low pressure venturi when water passes through the constricted section. Further, the nozzle has one or more holes which project through the nozzle's sidewall at the venturi to aspirate air into the nozzle. The vortex chamber is between the fluid conduit and the nozzle. The vortex chamber rotates the flow of water around the showerhead's longitudinal axis before the water enters the nozzle's venturi. This causes the water to swirl within the venturi's low-pressure zone to increase the venturi effect of aspirating air into water within the showerhead's nozzle.
