Definitions
- the present invention relates to a swirl chamber spray nozzle, which is designed for a side exit sprayer push button.
- It relates in particular to a nozzle for obtaining a better spray compared to existing vortex chambers.
- French patent application FR-2,853,635 discloses a side exit spray pushbutton comprising a vortex chamber with symmetry of revolution about a first axis, which has a central output and a peripheral input, and which is arranged between two moldings, generally coaxial, respectively an inner part and an outer part, nested one inside the other.
- An imprint that delimits a cavity forming said swirl chamber is formed inside the outer part, which further comprises an ejection duct opening on the one hand into the cavity, and on the other hand outside the button pusher, and extending through its wall from the center of said footprint.
- the two parts have faces inclined relative to a second axis of interlocking common to them, applying against each other.
- the impression is made on the inclined face of the outer part, and the inclined faces are oriented in a direction and at an angle sufficient to make possible a demolding of the outer part along the common axis (second interlocking axis) without damage the impression.
- the fluid to be sprayed is introduced into the vortex chamber with a certain flow rate through at least two supply channels opening tangentially into the chamber.
- the rate of injection of the fluid into the chamber generates an accelerated swirling rotary circulation (so-called "swirl") of the fluid in the chamber just before its ejection towards the outside of the pushbutton, causing the spraying of the fluid. .
- the duct of the vortex chambers is central and its axis corresponds to the axis of symmetry of revolution of the chamber.
- the ejection duct of the vortex chamber extends perpendicular to the common axis of the two parts, to allow spraying lateral. Also, the axis of the ejection duct is inclined relative to the axis of the vortex chamber.
- the inclination of the axis of the ejection duct creates a disturbance which imbalances the movement of the fluid injected into the vortex chamber at high speed. This movement is slowed, attenuated or even completely rolled, at the entrance of the ejection duct, which leads to obtaining a jet at the outlet of the duct, rather than obtaining the desired spray.
- the reason for obtaining a jet rather than a spray is as follows: the fluid is swirled in an axially symmetrical motion, and this movement is obtained in the vortex chamber around the central axis of the fluid. bedroom. This movement of the fluid in accelerated rotation is strongly disturbed at the approach of the ejection duct, because of the abrupt change of direction imposed by the inclined orientation of the ejection duct relative to the axis of the chamber.
- the present invention aims to overcome the problem of poor quality of spray which is related to the inclination of the axis of the ejection duct relative to the axis of the vortex chamber, proposing another solution compared to that consisting of to realize two channels of different sections.
- the present invention relates to a nozzle for spraying a fluid comprising a vortex chamber with symmetry of revolution about an axis Z of origin O, into which at least two fluid supply channels open.
- the chamber is provided with an ejection duct whose axis is inclined relative to the axis of symmetry of the chamber at an angle.
- the duct 4 is made in such a way that its axis ⁇ has an origin O '
- orientation of the conduit the direction of ejection of the fluid from the inside of the chamber to the outside of the spray nozzle.
- This flow remains symmetrical with respect to a certain axis.
- the distance separating the two origin O and O ' is at least equal to 60 ⁇ m, and preferably greater than or equal to 120 ⁇ m. According to a variant embodiment, for a tilt angle value of 60 °, the distance separating the two origins O and O 'is 150 ⁇ m.
- the channels open uniformly to the periphery of the chamber.
- the channels have the same section.
- the channels are oriented in a direction tangent to the periphery of said chamber.
- the channels have a curved and convex shape.
- the chamber is formed of a frustoconical cavity provided with a flat bottom where opens the upstream end of said conduit.
- the nozzle according to the invention thus makes it possible to obtain uniform sprays, with chambers connected to channels whose axis is inclined with respect to that of the axis of the chamber, in order to be able to be used in the sprays. pushers for lateral spraying of fluids.
- FIG. 1 is a schematic representation of a nozzle according to the invention in profile view, in an XYZ reference frame;
- FIG. 2 is another schematic representation of the nozzle shown in Figure 1, in profile, in an XY repository.
- the following description relates to an embodiment of a nozzle according to the invention which is particularly adapted to a push button designed to deliver a fluid laterally in the form of a spray, as described in the French patent application FR -2,853,635.
- the nozzle comprises a swirl chamber 1 with symmetry of revolution around a Z axis of origin O.
- the channels 2 and 3 have the same section, so that both channels have identical fluid flow capacities.
- the channels 2 and 3 open uniformly to the periphery of the chamber 1. In this way, it promotes a uniform distribution of the fluid in the chamber.
- FIG. 1 To further promote the swirling motion, it can also be expected to realize the channels in a curved and convex shape. This embodiment is suggested by FIG.
- the chamber 1 is formed of a frustoconical cavity provided with a flat bottom 5 which opens the upstream end of a conduit 4 for ejecting fluid towards the outside of the nozzle.
- the ejection duct 4 consists of a tubular element and has an axis ⁇ which is inclined at an angle ⁇ with respect to the axis of symmetry Z of the chamber 1.
- the duct 4 is made in such a way that its axis ⁇ has an origin O 'whose position is shifted by a distance d with respect to the origin O of the axis of symmetry Z.
- the distance d depends on the value of the inclination angle ⁇ of the duct.
- the direction defined by the straight line connecting the two origins O and O ' depends on the position and the section of the channels 2 and 3, and finally the direction of orientation between O and O' is opposite to the orientation of the duct 4, that is to say in the direction of ejection of the fluid to the outside of the spray nozzle.
- the vortex flow created in the chamber is all the more disturbed at the entrance of the ejection duct that the angle of inclination of the duct is high. Also, it has been found that the higher the angle of inclination, and the more we must seek to increase the imbalance in the chamber to obtain, at the outlet of the ejection duct a homogeneous spray. Also, by bringing the upstream orifice of the ejection duct of the outlet end of one of the channels 2 or 3, the disturbance caused by the inclination of the ejection duct is compensated by the imbalance created by means of bringing the duct inlet closer to the outlet of one of the channels.
- the direction of the straight line connecting O and 0 ' depends on the flow rate of the fluid introduced into the chamber and the movement of the swirling flow that it generates in the chamber. Concerning the vectorial direction of O towards O ', it is advisable to place O' in a direction opposite to the orientation of the conduit. According to the invention, as illustrated in FIG. 1, for a value of angle ⁇ greater than 20 °, the distance d is at least equal to 60 ⁇ m.
- the angle of inclination ⁇ of the duct is 60 °.
- the distance d between O and O ' is substantially 150 ⁇ m (+/- 20 ⁇ m).
- the point O ' is chosen on a straight line D whose direction is substantially parallel to the tangent of the swirling flow passing through the point O.
- the direction of the swirling flow of the fluid in the chamber is symbolized by the arrows S in FIG.
- This line D passing through O cuts the circle C in two points.
- the point O ' which is chosen from these two points in such a way that the vector 00' has a direction opposite to that of circulation of the flow (direction of flow symbolized by the arrows S), and particularly to its direction of ejection of the product from the bedroom and via the duct.
- the invention extends to any nozzle incorporating the characteristics of the invention or equivalent means.
