Definitions
- Spray head for a spray can for a spray can.
- the invention relates to a spray head for a spray can, comprising a hollow stem having a bore which is adapted to be brought into communication with the liquid space of the spray can, and which on the other hand, terminates near a spray nozzle having an exit aperture, so as to force liquid driven into said bore by the outward pressure of the spray can
- the droplets of the sprayed liquid formed in the nozzle will still contain driving agent which immediately evaporate, so that the droplets will be reduced which enhances the formation of a fine mist.
- This spray head can be constructed in various manners, as defined in the subclaims.
- Fig. 1 a diagrammatical representation of a spray head for elucidating the principle of the invention
- FIG. 2 and 3 cross-sections of practical embodiments of the spray head of the invention.
- a spray head 1 is shown in a simplified manner, which head comprises a stem 2 with a bore 3, which stem is to be mounted on a spray can, and is designed for opening a dispensing valve not shown when being pressed downwards. Then the liquid to be sprayed will be driven into the bore 3 by the gas or vapour pressure acting within the spray can.
- the bore 3 is continued by a transverse bore 4 of a spray nozzle terminating in a dispensing aperture 6. So far the present head 1 corresponds with the current spray heads.
- a jet pump 7 is diagrammatically indicated.
- This pump comprises a jet nozzle 8 through which the liquid driven through the bore 3 flows, said nozzle 8 opening into a wider chamber 9 communicating, via an additional bore 10, with the ambient air.
- air will be sucked inwards in the known manner through the bore 10 and will be mixed with the liquid, which will be enhanced'by arranging means for forming turbulences in the chamber 9
- the mist jet emerging from the aperture 6 is mixed with air to such an extent that the liquid droplets formed will not coalesce, and a fine mist is obtained
- the jet pump 7 diagrammatically shown can be realised in many other ways, e.g. in the form of a venturi tube. Moreover the location thereof in the bore 3 can be varied. it can be favourable to arrange it as closely as possible near the aperture 6, and this in view of manufacturing as well in view of the mixing effect.
- Fig. 2 a first practical embodiment of the spray head 1 is shown. The parts thereof corresponding with Fig. 1 have been indicated therein with the same reference numerals
- the transverse bore 4 terminates into a substantially annular chamber 11 into which a cylindrical cap 12 has been inserted which has a front wall 13 in which the aperture 6 is provided.
- the wall 13 defines, together with an end face 14 of a central piece 15 of the nozzle portion 5, a chamber 16 communicating with the bore 4 in which sloping baffles 17 can be arranged in order to allow the liquid to be brought in a revolving motion before emerging through the aperture 6.
- This tube end and the aperture 6 form together the jet pump 7.
- This embodiment of the nozzle 5 is of the current design with the exception of the additional tube 18 opening into the aperture 6 which adaptation can easily be realised.
- FIG. 3 shows still another practical embodiment in which, again, parts corresponding with Figs. 1 and 2 have been provided with the same reference numerals.
- the tube 18 has been omitted, and before the end face 13 of the cap 12 a disc 19 directed parallel thereto is provided which, together with this end face 13, defines a passage 10' forming the air suction passage.
- a disc 19 directed parallel thereto is provided which, together with this end face 13, defines a passage 10' forming the air suction passage.
- air suction openings 20 are provided, and in the centre of this disc an aperture 6' has been formed which is situated coaxially with the aperture 6 of the cap and has substantially the same diameter.
- the passage 10' can be provided, if required, with guiding baffles for imparting a revolving motion to the air flow sucked in, which motion, as the case may be, can be opposite to that of the revolving motion of the liquid caused by the baffles 17.

Abstract
L'invention concerne une tête de vaporisation pour une boîte de vaporisation, comprenant une tige creuse dont l'alésage est adapté pour être mis en communication avec l'espace de liquide de ladite boîte de vaporisation, et aboutit près d'un ajutage de vaporisation présentant un orifice de sortie, de manière à pousser le liquide entraîné dans ledit alésage au moyen de la force extérieure de ladite boîte de vaporisation, par ledit orifice, afin de vaporiser ledit liquide. Selon l'invention, on a prévu dans le chemin d'écoulement (3, 4, 6) du liquide, un passage faisant office de pompe à éjecteur (7) entraîné par l'écoulement de liquide poussé vers l'extérieur, dont le côté d'aspiration (10) communique avec l'air ambiant.The invention relates to a spray head for a spray box, comprising a hollow rod whose bore is adapted to be placed in communication with the liquid space of said spray box, and terminates near a spray nozzle. having an outlet orifice, so as to push the liquid entrained into said bore by means of the external force of said spray box, through said orifice, in order to vaporize said liquid. According to the invention, there is provided in the flow path (3, 4, 6) of the liquid, a passage acting as an ejector pump (7) driven by the flow of liquid pushed towards the outside, the suction side (10) communicates with the ambient air.
