DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to accessories for bathrooms, in this case the nozzles applied to showers with sprayers that transform the pressurised jet of water into a fine rain to be regulated and directed as desired.
The user can either freshen up by simply allowing the spray to run pleasingly over the body or can use it for a real wash spreading detergent preparations over the skin by hand.
Allowing for the relative positions of sprayer and user as well as the shape of a shower cubicle, the difficulty of satisfactorily combining washing the skin with detergent and running the water is well known; this includes turning taps on and off, opening and closing the detergent and then once again adjusting water heat and flow. The above invention avoids these drawbacks and ensures a more comfortable shower as will be explained below.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a nozzle for shower baths that comprises a sprayer substantially cup-shaped creating a mixing chamber through which the water passes, accessible from outside for insertion of some kind of toilet preparation.
In this way the water comes out already mixed with the detergent preparation which no longer need be applied by hand to the skin.
Said detergent, placed in the chamber inside the sprayer, may advantageously be in the form of a tablet.
The chamber is closed at the front by a cylindrical head with a perforated base through which water is sprayed. Inside said head is a plate with a spacer on which the detergent is placed. The purpose of this is to permit a regular flow of water mixed with detergent between the plate and the base, and down through the perforations. Said head is screwed onto the sprayer by threading on the outer face of the head and on the inner face of the sprayer. By simply unscrewing the above head the preferred quantity of bath detergent can be put in.
The nozzle here described comprises means for regulating the sprayer in either of two positions, for `washing` or for `rinsing`.
When in the washing position the water passes through the chamber and is mixed with the detergent inside. When in the rinsing position the water flows through passages outside said chamber.
In a preferred execution the nozzle is cup-shaped with a cylindrical body and axial hole in its base fitted externally with a threaded collar for screwing onto the end of a pipe leading in from the water mains.
Inside the cup formed by the nozzle is the sprayer and flow deflector. In addition to the central chamber closed at the front by the cylindrical head, the sprayer comprises an annular chamber, around the central one, open behind. The wall of the nozzle's cylindrical body penetrates inside said annular chamber. Said wall is thin and its inner diameter is greater than the lesser diameter of the annular chamber of the sprayer.
A cavity is thus created through which passes water down to the bottom facing outwards and perforated for spraying. In the base of the sprayer is a tapered axial expansion that faces towards the nozzle and comprises an axial hole. The flow deflector comprises an upper discoid base, perforated for the passage of water, and a lower head with a tapered back whose diameter is greater than that of the nozzle's axial hole, said lower head being connected to the discoid base by an axial stem that passes through the axial hole in the sprayer.
The diameter of said stem is less than the diameter of said axial hole to allow water to pass.
The base of the flow deflector rests on the annular seat of the nozzle's axial hole.
The tapered head lies inside the sprayer's central chamber. The distance between the base of the nozzle and the tapered back of the deflector head is appreciably greater than the thickness of the base of the sprayer at the point of its tapered expansion so as to permit axial movement of the sprayer to one or other of the two positions, `washing` and `rinsing` respectively, towards the nozzle or outside it. In the washing position contact is made be
