Definitions

  • a typical shower stall includes valves for regulating the relative flows of hot and cold water and an overhead showerhead from which rinsing water is dispensed.
  • Hair shampoo is stored in, and dispensed manually from, a container (typically plastic) from which it is either poured, squeezed, or manually pumped.
  • Cleansing soap is typically rubbed and dissolved from a“bar” of soap or, somewhat less commonly, pumped, poured, or squeezed from a container.
  • the most common methods of showering to which we have become accustomed result in the spillage of concentrated, slippery liquids onto the shower floor and cleansing-fluid waste.
  • certain aspects of showering are somewhat inconvenient and invariably involve the inefficient use of both hands to achieve such steps as dispensing soap for application to one’s body.
  • a handheld showerhead has a proximal end and a distal end opposite the proximal end.
  • An elongated handled by which a user grasps the showerhead extends from and along the proximal end toward the distal end.
  • the distal end is dimensionally enlarged (e.g., bulbous) relative to the handle and has defined therein an array of water- ejection apertures from which water can be selectively ejected.
  • a water supply conduit in fluid communication with the water-ejection apertures extends longitudinally through the handle.
  • the water supply conduit is defined by the showerhead itself. That is, the showerhead defines on its interior a channel that serves as the water supply conduit and extends from the proximal end, through the handle, and to the water ejection apertures at the distal end.
  • the water supply conduit is configured to channel supply water introduced through an input opening in the proximal end to the distal end for forcible ejection through the water-ejection apertures.
  • a detergent supply system including a detergent reservoir.
  • the detergent reservoir is selectively refillable through a selectively openable and closable filler opening through which a quantity of liquid detergent can be poured from a container for storage within the reservoir.
  • the detergent reservoir is selectively rendered in fluid communication with the water supply conduit through a detergent port. More specifically, the detergent reservoir is in fluid communication with a detergent port that facilitates the selective flow of detergent from within the detergent reservoir into the water supply conduit extending longitudinally through the handle. Detergent that flows through the detergent port mixes with water flowing through the water supply conduit toward and out of the water-ejection apertures.
  • the detergent supply system further includes a button accessible to the user from the exterior of the handheld showerhead.
  • the button is mechanically linked to a port closure that selectively opens and closes the detergent port. More specifically, movement of the button in a first direction causes the port closure to close the detergent port and prevent the flow of detergent from the detergent reservoir into the water supply conduit. Conversely, movement of the button in a second direction opposite the first direction causes the port closure to open the detergent port and allow the flow of detergent from the detergent reservoir into the water supply conduit.
  • the detergent reservoir and the detergent port are situated more proximate the distal end than to the proximal end of the handheld showerhead. Moreover, the detergent reservoir extends at least partially within the enlarged distal end. While situating the detergent reservoir at least partially within the enlarged distal end is a counterintuitive arrangement, it will be appreciated through the present disclosure that such a configuration facilitates a larger capacity for detergent storage“onboard” the handheld showerhead. Additionally, if at least a portion of the detergent reservoir is incorporated within a bulbous distal end, the detergent supply system may include a larger, more-convenient filler opening and closure than might be accommodated elsewhere along the length of the handheld showerhead. A larger filler opening allows the detergent reservoir to be filled more quickly without wasteful and messy spillage of liquid detergent, while a larger closure associated with a larger filler opening is easier to open, close, and otherwise keep track of and manipulate.
  • exfoliator tips protruding from the enlarged distal end.
  • the exfoliator tips themselves may be variously configured in shape, size, and relative hardness for example. While some exfoliator tips may be relatively smooth and/or soft to render them perhaps more suitable for massaging than exfoliating, all such similar protrusions at the distal end are nevertheless referred to as “exfoliator tips” for purposes of brevity and simplification in the description.
  • the water-ejection apertures are defined in and through the exfoliator tips, while in other versions, the water-ejection apertures are separate and distinct from the exfoliator tips. Included within these possibilities are distal ends exhibiting various combinations of exfoliator tips and water-ejection apertures.
  • all exfoliating tips may be separate and exclusive of water-ejection apertures, (ii) some exfoliator tips may include water- ejection apertures, while other exfoliating tips do not, (iii) some water-ejection apertures may extend through exfoliator tips, while others do not, or (iv) all exfoliating tips include water-ejection apertures, while the distal end also includes no water-ejection apertures that are separate and apart from exfoliator tips.
  • the distal end carries an exfoliator head that is selectively removable from and attachable to the distal end of the handheld showerhead.
  • the exfoliator head carries the exfoliator tips. In this way, the exfoliator tips can be replaced through replacement of the exfoliator head.
  • disparate exfoliator heads carrying disparate types of exfoliator tips will be selectively attachable to the distal end so that, for example, a user can change out exfoliator heads depending on desired effect (e.g., heavy exfoliation versus mild exfoliation combined with massage).

  • FIG. 2 depicts a left-side view of the handheld showerhead of FIG. 1 ;
  • FIG. 3 is a back view of the handheld showerhead of FIGS. 1 and 2;
  • FIG. 4 is a left-side cross-sectional view of a detergent-dispensing handheld showerhead
  • FIG. 4A is an enlarged detail sectional view of a subsection of the handheld showerhead shown in FIG. 4;
  • FIG. 5 is an exploded view of a detergent-dispensing showerhead
  • FIG. 5A shows a first type of exfoliator head that is selectively attachable to the handheld showerhead shown in FIG. 5;
  • FIG. 5B depicts a second type of exfoliator head that is selectively attachable to the handheld showerhead shown in FIG. 5;
  • FIG. 5C illustrates a third type of exfoliator head that is selectively attachable to the handheld showerhead shown in FIG. 5.
  • FIGS. 1 , 2 and 3 Shown in FIGS. 1 , 2 and 3 are three views of a detergent-dispensing handheld showerhead 10. More specifically, in moving from left to right in the drawing sheet, there are shown (i) a front view in FIG. 1 , (ii) a left-side view in FIG. 2, and (iii) a back view in FIG. 3.
  • the overall handheld showerhead 10 has a proximal end 12, including an elongated handle 13 configured for grasping by a user, and distal end 14 opposite the proximal end 12.
  • the distal end 14 is dimensionally enlarged relative to the handle 13 and has defined therein an array of water-ejection apertures 16 from which wash water is forcibly dispensed (ejected). “Enlargement” of the distal end 14 relative to the handle 13 may manifest in, for example, the distal end 14 extending laterally beyond (wider) than the handle 13 overall, or in being otherwise relatively“bulbous” relative to the handle 13. Defined and extending longitudinally through the handle 13 is a main water supply conduit CM.
  • the water supply conduit CM is in fluid communication with the water-ejection apertures 16 and configured to channel supply water introduced through an input opening 12o into the proximal end 12 -- by, for example, a flexible supply hose (not shown) selectively coupleable to the proximal end 12 - to the distal end 14 for forcible ejection through the water-ejection apertures 16.
  • the showerhead 10 further includes a detergent supply system 20, which detergent supply system 20 itself includes a detergent reservoir 30.
  • the entirety of the detergent supply system 20 is carried by and/or defined within the handheld showerhead 10, a characteristic that distinguishes it from the illustrative references listed in the background, and other existing systems that draw upon remote sources/reservoirs of detergent.
  • the detergent be a liquid or gel in the form of at least one of (i) body wash, (ii) hair shampoo, (iii) or a combination liquid intended for washing both hair and skin.
  • the detergent reservoir 30 is selectively refillable through a filler opening 32, with the filler opening 32 being selectively openable and closable with a closure 34 (e.g., a threaded or snap-fit cap 34C).
  • the detergent reservoir 30 further includes - or is at least in fluid communication with - a detergent port 36 that facilitates the selective flow of detergent from inside the reservoir 30 into the main water supply conduit CM for mixing with wash water flowing through the main water supply conduit CM toward the water-ejection apertures 16.
  • the detergent supply system 20 includes a detergent-supply actuator 40 including a button 42 that is accessible to the user from the exterior of the handheld showerhead 10. Movement of the button 42 in a first direction closes the detergent port 36, while movement in a second direction opens the detergent port 36. More specifically, the button 42 is mechanically linked through an actuator linkage 44 to a port closure 46 (e.g. a plug or gate) that selectively opens and closes the detergent port 36 in response to corresponding actuation of the button 42 in opposed first and second directions. In various embodiments, movement of the button 42 in first and second directions is slidable movement along the length of the handheld showerhead 10.
  • a detergent-supply actuator 40 including a button 42 that is accessible to the user from the exterior of the handheld showerhead 10. Movement of the button 42 in a first direction closes the detergent port 36, while movement in a second direction opens the detergent port 36. More specifically, the button 42 is mechanically linked through an actuator linkage 44 to a port closure 46 (e.g. a plug or gate) that selectively opens
  • the detergent reservoir 30 and the detergent port 36 are situated more proximate the distal end 14 than to the proximal end 12 of the handheld showerhead 10. Moreover, as in the embodiment depicted, it may be advantageous for the detergent reservoir 30 to extend at least partially within the enlarged distal end 14 in order to at least one of (i) facilitate a larger capacity for detergent storage and (ii) accommodate a larger, more-convenient filler opening 32 and closure 34 than might be accommodated elsewhere along the length of the handheld showerhead 10.
  • the button 42 of the detergent-supply actuator 40 be more proximate the distal end 14 than to the proximal end 12 of the handheld showerhead 10. It will be appreciated that in embodiments so configured, the user would typically actuate the button 42 with the hand opposite the hand grasping the handle 13 when in use, which, in many instances, is more ergonomic than an arrangement in which the button 42 would be actuated by the same hand grasping and supporting the handle 13.
  • situating the button 42 more proximate the distal end 14 than to the proximal end 12 furthermore allows the length of the actuator linkage 44 to be minimized when the detergent port 36 and port closure 46 are also situated at or adjacent the distal end 14.
  • opening of the detergent port 36 allows at least one force to act on detergent in the detergent reservoir 30 and cause it to flow into the main water supply conduit CM.
  • the“at least one force” includes gravity.
  • the main water flow is constricted in the vicinity of the detergent port 36 so that the main water flow accelerates, thereby creating a localized drop in pressure that draws detergent out of the reservoir 30 through the detergent port 36 by action of the“Venturi Effect.” When this occurs, wash water mixed with detergent is ejected from the water-ejection apertures 16.
  • various embodiments are configured with protrusions on the enlarged distal end 14. These protrusions are designated “exfoliator tips 18.”
  • the water- ejection apertures 16 are defined in and through the exfoliator tips 18.
  • the exfoliator tips 18 can be rubbed along a user’s body parts to exfoliate the skin as water or water and detergent are ejected through the water-ejection apertures 16.
  • various configurations include changeable exfoliator heads 70.
  • the exfoliator heads 70 also carry and define the water-ejection apertures 16, and are selectively removable from and attachable to the distal end 14 of the handheld showerhead 10 through, for example, threads.
  • a handheld showerhead 10 may be sold as part of a kit including a plurality of at least two selectively changeable exfoliator heads 70. Additionally or alternatively, a handheld showerhead 10 may be sold with a single changeable exfoliator head 70, with aftermarket availability of additional and/or replacement exfoliator heads 70.
  • exfoliator tips 18 themselves are changeable by, for example, threading into and out of the exfoliator head 70.
  • the exfoliator head 70 itself is either removable or non-removable from the enlarged distal end 14 handheld showerhead 10. In either event, the changeability of the exfoliator tips 18 renders them replaceable when worn out.
  • combinations of different types of exfoliator tips 18 can be incorporated contemporaneously into the exfoliator head 70. For instance, a user could create a customized arrangement of soft, medium, and/or hard exfoliator tips 18. In addition to variations in relative hardness of the exfoliator tips 18, there could be variations in other parameters such as, for example, size or shape. There could be relatively smooth convex-curved exfoliator tips 18 more conducive to tissue massaging or relatively pointed or spiked tips 18 more conducive to aggressive exfoliation.
  • the handle 13 of different embodiments is elongated to various alternative extents in order to facilitate ease of use and reachability of normally difficult-to-reach areas of the body, such as the upper back.
  • An elongated handle 13 facilitates selective contact between the exfoliator tips 18 and every part of a user’s body.
