Definitions

  • the present invention relates to a sprinkler head device intended to equip showers or hand showers.
  • 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.
  • Equivalent devices are also proposed in American patents US-A-3,104,829 or US-A-3,146,674, these devices also comprising a device capable of imparting a vortex movement with a liquid jet, so as to obtain a mixing of water and clean air to maintain at the outlet of the device a rain shower comparable to that obtained conventionally, for a significantly reduced water consumption.
  • the helical core proposed as 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 to 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 can be brought closer or further apart forming the front face of a concentric sleeve mounted sliding around said bushing.
  • the position of the calibrated nozzle is therefore fixed and the intensification of the swirling water jet coming from the upper deflector means which results therefrom 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 structure of the central portion of the jet is preserved all along 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 deviation, said central portion of the jet.
  • 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 vanes 7 are inclined vertically by an angle close to 45 °, 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 7 a , the set of edges 7 a defining the same vertical plane (passing, in addition, 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 mix it with the air contained in the interior chamber 6 - it will be noted, in this case, that no air is supplied, unlike certain known devices designed to save water.
  • the upper part 8 a 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 also provided so as to provide a slight longitudinal clearance to the deflector 5, thus delaying its scaling which would be faster if this deflector 5 was fixed.
  • each blade 7 has a lower notch 7 b promoting the grouping of swirling water streams along the central axis 8, which ends, moreover, by a point 8 b recomposing said threads in a single central vortex jet, making it possible to feed the jet 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. Because it is removably mounted at the bottom of the frustoconical inner chamber 9, 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 going 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 9 was provided around an orifice provided in the center and in the bottom of said cylindrical inner 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, as in Figure 3, be made 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 distributed by a plate of pierced outlet 12 a forming the front face of said sleeve 12.
  • this outlet plate 12 a 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 12 a 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 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 with the liquid jet leaving the outlet plate 12 a .
  • the sleeve 12 abuts, by an annular claw 12 b being internally offset at its top, against an annular shoulder 2 b projecting, formed for this purpose along the sleeve 2.
  • the sleeve 2 is grooved, the grooves 2 c providing successive annular notches cooperating with the annular claw 12 b ; in this respect, said annular claw 12 b can be formed by a continuous flange, or by a more or less regular succession of lugs, the choice of embodiment of said claw 12 b depending on the blocking firmness that one wants to obtain .
  • the sleeve 12 can thus rotate freely around the sleeve 2, the annular claw 12 b moving with little friction in the annular groove 2 c in which it is located.
  • the sleeve 2 is provided at its lower end with an annular bore 2 e which cooperates, for the centering of the sleeve 12, with an annular ring 12 c extending towards the inside of said sleeve 12 relative to the drilled outlet plate 12 a .
  • the guide of the sleeve 12 is also ensured by the friction contact of its inner wall on the outer wall of said socket 2.
  • the perforated outlet plate 12 to form with the ring 12 c a single piece which is attached to the front of the sleeve 12 after the screwing by force of the sleeve 2 on the external thread 1 a of the water pipe 1.
  • a tightening key for example, a hexagon wrench
  • the sleeve 2 is threaded rather than fluted, the threads 2 d then cooperating with the annular claw 12 b of the sleeve 12 which can then be moved along the sleeve 2 by rotation.
  • the annular claw 12 b has sufficient elasticity so that the sleeve 12 can be simply pulled along the sleeve 2, the threads 2 d then behaving in the manner of the grooves 2 c of a sleeve 2 grooved ( Figure 1).
  • the inclination of the threads 2 d of a threaded socket 2 may be sufficiently small so that the differences with a set of adjacent grooves 2 c are negligible.
  • the outlet plate 12 has here a single piece with the cylindrical body 12 d (fig. 1) of the sleeve 12, an upper clip 16, of the type a latch cylinder, which fits into the space provided for this purpose between the outer wall of the sleeve 2 and the inner wall of said cylindrical body 2 d ; an annular lug 16 a of the clip 16 then fits into a groove 12 e formed in the cylindrical body 12 d 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.
  • the field of the invention is that of sprinkler head devices intended to equip, in particular, showers or hand showers.
