Definitions

• the present invention relates to a sprinkler head device intended to equip showers or hand showers.
• sprinkler heads designed, for example, to reduce water consumption through the addition of devices, such as nozzles, limiting the water flow, or also aimed at obtaining a jet. adjustable power and width.
• this spraying device comprises a helical inner core imparting a rotary movement to the liquid jet, this helical core being disposed in a concentric sleeve, preferably axially movable, which makes it possible to modify the free space between said helical core and said movable sleeve and, consequently, to regulate the fineness of spraying.
• the helical core proposed as a deflector means, imparting a rotary movement to the liquid jet, slides coaxially inside a frustoconical bore sleeve making it possible to simultaneously obtain either a corresponding vortex a high degree of dispersion and spraying of a liquid jet intense, that is to say a set of helical veins of water surrounded by a conical liquid sheet, without tangential component, which attenuate the vortex movement and the degree of fineness of the spraying.
• the present invention aims to remedy these drawbacks by proposing a device with a sprinkler head intended to equip showers or hand showers at the outlet of a water pipe, characterized in that it comprises at least one means deflector constituted by a plurality of peripheral blades of a central axis, arranged coaxially in a first interior chamber, preferably cylindrical, which is formed in a socket screwed by force to the end of said water pipe, said first chamber being extended downwards by a second inner chamber, cylindrical or conical, leading to a calibrated nozzle opposite which a pierced outlet plate forming the front face of a concentric sleeve mounted sliding around said bush can be brought closer or further apart.
• the position of the calibrated nozzle is therefore fixed and the intensification of the swirling water jet coming from the resulting upper deflector means is, in this way, in no way dependent on the longitudinal position of the concentric sleeve, sliding around the sleeve, and which carries, at its end, an outlet plate pierced with holes whose longitudinal displacement makes it possible to vary the angle of diffusion of the liquid jet.
• the drilled outlet plate forming the front face of the sleeve has a central hole, preferably oblong, surrounded by smaller peripheral holes, regularly distributed around said central hole; in this way, there is a first intermediate position of the sleeve along the sleeve, for which the liquid jet diffused at the outlet of the fixed calibrated nozzle just reaches the limit between the central hole and the peripheral holes of the outlet plate , this first intermediate position determining the limit beyond which the jet is intense.
• the blade deflector means prefferably be provided with auxiliary means making it possible to feed the liquid jet leaving the nozzle at its center and, in this regard, the present invention proposes two variants, to know :
• Each blade of the deflector means has a lower notch favoring the grouping of certain water streams along its central axis, said central axis ends with a point recomposing said streams of water in a single central vortex jet of reduced viscosity.
• the central axis of the paddle deflector means is bored longitudinally to form a tube allowing passage to a non-vortex central water flow allowing direct feeding of the jet at its center.
• the blade deflector means do not in any way harm the water saving that the blade deflector means provides upstream of the nozzle.
• the central portion of the liquid jet thus treated is small enough not to influence the behavior of the liquid animated, at the periphery, of a vortex movement.
• the structure of the central portion of the jet is preserved throughout its path in the sprinkler head device since, as mentioned above, the outlet plate is pierced in its center by an oblong hole, the main role of which is to let pass, without loss of power or deflection, said central portion of the jet.
• FIG. 1 shows two half-views, one exterior, the other in cross section, of a sprinkler head device according to a first embodiment of the invention
• FIG. 2 is a perspective view of a first variant of a blade deflector means used in the sprinkler head device shown in FIG. 1,
• FIG. 3 shows two half-views, one exterior, the other in cross section, of a second embodiment of a sprinkler head device according to the present invention
• FIG. 4 is a perspective view of the blade deflector means used in the sprinkler head device shown in FIG. 3,
• Figure 5 is a top view of the deflector means shown in Figure 4.
• the sprinkler head device according to the invention which is mounted at the end of a water pipe 1 so as to constitute a shower device, comprises a socket 2, cylindrical and hollow, which is provided, at its upper part, with an internal thread 2a, intended to be screwed by force onto the external thread la of said pipe 1.
• This socket 2 serves as an assembly body for a set of means such as:
• This strainer 3 is placed at the lower end of the internal thread 2a of the sleeve 2, in positive support on an annular edge 4 in internal offset with respect to said thread 2a; the depth of this annular edge 4 is less than the thickness of the cylindrical strainer 3, so that the latter can serve as a seal between the water pipe 1 and the sleeve 2.
• a deflector means 5 capable of creating swirling streams of water modifying the apparent viscosity of the fluid, and providing water savings.
• This deflector means 5 is located in a first cylindrical interior chamber 6, of diameter equal to the interior diameter of the annular edge 4.
• the deflector means 5 is constituted by a plurality vanes 7 peripheral to a central axis 8, collinear with the axis of symmetry of the cylindrical sleeve 2; the blades 7 are inclined vertically by an angle close to 45 e , and follow one another regularly from the top to the bottom of the central axis 8.
• each of the blades 7 has an upper edge 7a, the set of edges 7a defining the same vertical plane (passing, moreover, through the central axis 8).
• the fluid having passed through the cylindrical strainer 3 slides over the vanes 7 which impart to this fluid a swirling movement, and stir it with the air contained in the interior chamber 6 -
• the upper part 8a of the central axis 8 maintains the deflector means 5 on the axis of symmetry of the interior chamber 6, thanks to a hole drilled in the center of the strainer 3.
• the height of this chamber 6 is furthermore provided so as to provide a slight longitudinal play with the deflector means 5, thus delaying its scaling which would be faster if this deflector 5 was fixed.
• each blade 7 has a lower notch 7b promoting the grouping of the swirling water streams along the central axis 8, which ends, moreover, by a tip 8b recomposing said nets in a single central vortex jet, allowing the jet to be fed at its center.
• the first interior chamber 6 is extended downstream by a second frustoconical interior chamber 9, tapering progressively downwards to serve as a housing for a removable nozzle 10 intended to increase the power of the jet rendered vortex, upstream, by the deflector means 5.
• This nozzle 10 which also increases the diffusion of the jet, is calibrated according to the maximum desired water flow rate.
• the nozzle 10 can be easily replaced, which makes it possible to adapt its internal diameter to the pressure available on the water distribution network.
• the central axis 8 of the deflector means 5 is bored longitudinally to have the shape of a tube allowing passage to a central flow of water escaping the swirling movement imparted to the flow peripheral by the vanes 7. This arrangement also makes it possible to feed the jet at its center, the non-vortex central jet exiting at the bottom of said tube heading towards the removable nozzle 10, also calibrated according to the maximum desired water flow rate.
• the second interior chamber 9 is not frustoconical but simply cylindrical, the deflector means 5 then coming to bear on a shoulder 11 separating the two interior chambers 6 and 9.
• the nozzle 10 is supported by a shoulder 10a on a bank 9a formed around an orifice provided in the center and in the bottom of said cylindrical interior chamber 9.
• the bore formed in the nozzle 10 can either, in the manner of FIG. 1, consist of two frustoconical parts surrounding a cylindrical central part, determining its minimum diameter (Venturi effect), or, in the manner of Figure 3, consist of a single cylindrical part of constant diameter.
• a sleeve 12 is slidably mounted on the sleeve 2 and allows the intensified vortex jet coming out of the nozzle 10 to be more or less widely diffused by a plate of pierced outlet 12a forming the front face of said sleeve 12.
• this outlet plate 12a has a central hole 13, preferably circular or oblong, which is surrounded by smaller peripheral holes 14 and regularly distributed around said central hole 13.
• the outlet plate 12a has a thickness sufficient for the wall of the central hole 13 to constitute a guide for the intensified vortex jet coming from the nozzle 10. In this way, there is a position of the sleeve 12 along the sleeve 2 for which the water jet has a minimum angular opening and a maximum power; conversely, when, in accordance with the right external half-views of FIGS.
• the sleeve 12 is in maximum elongation downwards, the intensified vortex jet coming from the nozzle 10 can reach the peripheral holes 14, making lose its power to the liquid jet leaving the outlet plate 12a.
• the sleeve 12 abuts, by an annular claw 12b located in internal offset at its top, against an annular shoulder 2b projecting, formed for this purpose along the sleeve 2.
• the sleeve 2 is grooved, the grooves 2ç_ providing successive annular notches cooperating with the annular claw 12b; in this regard, said annular claw 12b can be formed by a continuous flange, or by a more or less regular succession of lugs, the choice of embodiment of said claw 12b depending on the blocking firmness that one wishes to obtain.
• the sleeve 12 can thus rotate freely around the sleeve 2, the annular claw 12b moving with little friction in the annular groove 2ç_ in which it is located.
• the sleeve 2 is provided at its lower end with an annular bore 2e which cooperates, for the centering of the sleeve 12, with an annular ring 12c. extending inwardly of said sleeve 12 relative to the pierced outlet plate 12a.
• the guide of the sleeve 12 is also ensured by the friction contact of its inner wall on the outer wall of said sleeve 2.
• the drilled outlet plate 12a forms with the ring 12ç_ a single piece which is attached to the front of the sleeve 12 after screwing by force of the sleeve 2 on the external thread 1a of the water pipe 1.
• a tightening key for example, a hexagon wrench
• the sleeve 2 is threaded rather than fluted, the threads 2d then cooperating with the annular claw 12b of the sleeve 12 which can then be moved along the sleeve 2 by rotation.
• the annular claw 12b has sufficient elasticity so that the sleeve 12 can be simply pulled along the sleeve 2, the threads 2d then behaving in the manner of the grooves 2c of a grooved sleeve 2 (FIG. 1).
• the inclination of the threads 2d of a threaded bush 2 may be sufficiently small so that the differences with a set of adjacent grooves 2c are negligible.
• the outlet plate 12a here forms a single piece with the cylindrical body 12d (fig.l) of the sleeve 12, an upper clip 16, of the type of a latch cylinder, fitting into the space provided for this purpose between the outer wall of the sleeve 2 and the inner wall of said cylindrical body 2d_; an annular lug 16a of the clip 16 then fits into a groove 12e formed in the cylindrical body 12d of the sleeve 12 and prevents the removal of said clip 16, said sleeve 12 thus having an external shape similar to that proposed as the first variant in FIG. 1.
