A spray arrangement, particularly a brush-like body-cleaning and/or massage device, particularly a toothbrush (1) with at least a nozzle body (10′) may be coupled to a hollow handle which is connectable by a hose to a water faucet. Nozzle body (10′) is preferably a fluidic oscillator without moving
A spray arrangement, particularly a brush-like body-cleaning and/or massage device, particularly a toothbrush (1) with at least a nozzle body (10′) may be coupled to a hollow handle which is connectable by a hose to a water faucet. Nozzle body (10′) is preferably a fluidic oscillator without moving parts. The hollow handle may receive into a metering cartridge a rod of a slow-to-dissolve active substance. The handle is provided with a removable elongated cap whose forward end may be coupled securely irrotationally with tube (5) of the cleaning brush. Moreover, the cap includes a manually actuatable water valve which is manually displaceable into the open position against a spring force and/or opposing water pressure. The water valve is preferably formed as a multi-step slide valve piston (68) with a conical shut-off member (72). Bristles (4) of the body cleaning device are preferably arranged on a bristle plate (3) which is held by snap-fastening means on a bristle carrier part (2) in easily exchangeable manner, whereby bristle plate (3) and bristle carrier part (2) in combination with tube (5) and a tunnel-like recess for receiving the nozzle body (10′) form, for example, the toothbrush (1).

For use in a brush-like body-care cleaning or massage device including at least one spray nozzle for discharge of fluid at the brush-like device, a handle section comprising, in combination: (a) a channel for passage of said fluid, said channel having an upstream end adapted to be connected to a source of pressurized fluid, and a downstream end; (b) an upstream tube section forming said upstream end of said channel and secured at one end thereof to a supply hose, the other end of said upstream tube section being releasably coupled to a dowmstream tube section having a valve member and forming said downstream end of said channel and carrying a handle pressure knob at the exterior of said dowmstream tube section for manually operating said valve member, said downstream tube section having an upstream end and further including at a forward end remote from said upstream tube section, coupling means for connecting the handle section to a brush tool; (c) a first opening transverse to said downstream end of said channel passing through said downstream tube section for receiving said valve member operatively associated with an extension member having one end thereof reaching to and operable from the exterior of the handle at said dowmstream tube section for selectively manually operating the movement of said valve member; (d) said first opening including a valve seat section of a concavely conical configuration disposed transversely of said downstream end of said channel and crossing it at a point between the upstream and downstream ends of said downstream tube section; (e) said valve member including an elongated conical stopper section having the surface thereof made from a resilient sealing material, said stopper section having a minor base-end portion and a major base-end portion and being complementary with said valve seat section, said stopper section being integral with a first cylindric valve section and with a second cylindric valve section, said first and said second cylindric valve sections being coaxial with said conical stopper section and being disposed one at each end of said conical stopper section, said first and said second cylindric valve sections being slidably received in a first cylindric channel section and a second cylindric channel section of said first opening, respectively; (f) the diameter of said second cylindric valve section being uniform and smaller than the diameter of said first cylindric valve section, the diameter of said first cylindric valve section being uniform, one end of said second cylindric valve section being adjacent said minor base portion and the other end being associated, via said extension member, with said handle pressure knob; (g) said first cylindric valve section being disposed at said major base-end portion of said stopper section and having a front-face portion turned away from said stopper section and disposed within said first cylindric channel section; (h) a first annular gap formed between siad conical stopper section and said first opening when said valve seat section slides away from said valve seat to open so as to allow fluid pressure from said channel to act on said conical stopper section of said valve member; (i) a first annular recess formed in said downstream tube section coaxially surrounding said first cylindric channel section, and creating a wall for said first cylindric channel section, said wall having a set back inner rim, said first annular recess being closed with a cover having an inner side so that a second annular gap is created between said inner side of said cover and said setback inner rim and so that said second annular gap is closed fluid tight with respect to ambient; (j) a coil spring, said coil spring having one end engaged with said front-face portion of said first cylindirc valve section and the other end engaged with said cover, a second opening communicating with said channel for subjecting said front-face portion of said first cylindric valve section to fluid pressure which, in the absence of handle pressure, and, together with said coil spring, urges valve member into a closed position, whereby, in the absence of fluid and handle pressure, said spring urges said valve member into the closed position, and whereby said fluid pressure passing through said first annular gap when said valve member slides away from said valve seat acts on said conical stopper section to augment the movement of said valve member to open from said valve seat; (k) said extension member having a stem including a peripheral groove for receiving a sealing ring for engaging the wall of said second cylindric channel section, said groove being limited by an annular shoulder of said second cylindric valve section and by a base of a cylindric sleeve fixedly secured to a free-end portion of said stem, said cylindric sleeve being integral with said pressure knob and having a first cylindric outer surface slidably received in said second cylindric channel section which is closed to the exterior with said sealing ring.
