Definitions

  • the present invention relates to a head generation and projection of foam, especially for a fire extinguisher.
  • Some fire extinguishers contain a fluid, usually a mixture of water and a chemical additive capable of emulsifying with air to form an extinguishing foam.
  • the projection heads that the known devices have the disadvantage of having a complex structure. Indeed, these heads include emulsion chambers with insertion holes air, means for emulsifying the mixture and air, especially turbines or chamber shapes suitable for producing a vortex flow, and screens or sieves, placed inside a tubing of diffusion of the foam.
  • the present invention aims to remedy this disadvantage, by providing a generation head and foam projection, producing good foam quality and quantity, while having a simple structure.
  • the head it concerns includes, so known per se, a foam diffusion tube produced.
  • the head according to the invention thus does not include any mobile turbine-type unit, no emulsion chamber of complex structure, communicating with the outside by air intake holes, and no grate or screen diffusion.
  • this head can be made of molded synthetic material.
  • the tubing has a shape substantially conical, widening in the direction of the foam projection.
  • the duct openings do not are thus not perpendicular to the direction of projection of the foam, but inclined outwards, according to the inclination of the wall of the tubing. This tilt favors the deflection of the jets by the boss.
  • conduits, walls, openings, the aforementioned boss and tubing are arranged in a socket attached to the free end of the head.
  • the boss has a shape rounded, especially hemispherical, favoring the deflecting the jets and preventing them from breaking before they collide.
  • the spray head includes four conduits.
  • the head includes a projection control valve, actuated by a mechanism.
  • the head has a butt-shaped part and a projection cannon shape, and includes a trigger to control the foam projection.
  • Figure 1 shows the generation 1 head and of foam projection that includes a device fire extinguisher (not shown).
  • This device includes a pressure tank connected to the head 1 by a flexible hose, this tank containing a mixture of water and a chemical additive capable of emulsifying with air at head 1 to form a foam fire extinguisher.
  • This head 1 has an internal body 5, a external housing 6 enveloping the body 5, a valve projection control, actuated by a housed mechanism in the body 5, a socket 7 ensuring the generation of the foam and a ring 8 for mounting this socket 7 on the free end of the body 5.
  • the body 5 and the housing 6 each have a part 5a, 6a forming a stick and a part 5b, 6b forming a projection "cannon".
  • Parts 5a and 5b define a conduit main fluid inlet 10, connected, at the level of the base of part 5a, to flexible hose (not shown) of the device.
  • This conduit 10 is unique at the level of the part 5a and divides in part 5b in two lateral conduits 10a, 10b which join behind the socket 7.
  • this part 5b comprises, between the lateral conduits 10a, 10b, a wall tubular 12 defining an axial bore, this bore being closed at its end opposite to the sleeve 7.
  • the part 5b also includes a housing 13 transverse to this bore, communicating with this bore and opening on the outside of the body 5, on either side of this latest.
  • Part 5b further includes tubing threaded 15, projecting coaxially to the bore of the side of the free end of the head 1, this tubing 15 comprising the sleeve 7 and the ring 8.
  • a spring 16 and a rod 17 are engaged and can slide into the bore.
  • Spring 16 carries against the bottom of the bore and against one end rod 17.
  • the other end of the rod 17 projects from the bore, and comprises a pad 20 of resilient material.
  • the end of the pad 20 has a conical shape, while the face of the socket 7 facing the interior of the head 1 comprises a conical seat 21 of same slope.
  • the end of the pad 20 can come into contact of this conical seat 21 with sealing, and is normally held in this position by the spring 16, this the latter being compressed when the pad 20 is in contact from seat 21.
  • the rod 17 also includes a housing transverse 22, arranged at height and opposite the housing 13.
  • the two housings 13 and 22 are crossed by a trigger 25, pivotally mounted on the body 5 by means of a axis 26.
  • This trigger 25 projects beyond the housing 6 through a slot 27, and comes to bear against the wall of the rod 17 delimiting the housing 22 on the side opposite the free end of the head 1.
  • a pressure exerted on the trigger 25 so bringing it closer to part 6b makes it possible to compress the spring 16 and move the pad 20 away from the seat 21, therefore control the flow of the fluid outwards, through bush 7.
  • the case 6 consists of two half-shells, one of which is partially cut on the figure 1. These two half-shells have flanges 30 body 5 and are assembled to each other by engagement of nipples or screws that includes one of them in corresponding holes 31 arranged in the wall of the other.
  • the ring 8 comprises, for its part, a shoulder able to bear against this shoulder 42 and a thread allowing its screwing on the thread of the tubing 15 so as to clamp the sleeve 7 between it and the end of this tubing 15.
  • the present invention thus makes it possible to obtain this result by means of a head 1 having a very structure simple and inexpensive to manufacture, which allows remedy the disadvantages of generation heads and projection of foam according to the prior art.
