Description

 The subject of the present invention is a nozzle breaker adaptable to a water tap making it possible to obtain three forms of jet with corresponding different flow rates.

 In the field of nozzle breakers #, it is known from patent EP 0276-416 a device # itif with orientable flow with adjustable water jet, screwable on the outlet of the taps, the adjustment of the water jet is obtained by rotation of a ring allowing either to obtain a central jet or a peripheral jet but such a device does not allow three different flow rates and three forms of jets by a simple, alternative action and to present, moreover, a playful interest in from an aesthetic form (animals, fruits, characters, ...).

The object of the invention is to solve such a problem and aims at a jet-breaking nozzle. This nozzle is intended to regulate the flow of water from a tap. It consists of adaptation means on the end of a tap, of a filter, of a conduit, provided at the end with a closed central part, surrounded by lateral openings and with a sleeve sliding on said conduit. provided at the lower end with a central opening with an outside diameter at least equal to that of the closed central part of the duct, bordered at its periphery by a plate perforated with holes. Said sleeve and Said duct comprise elastic retaining means in the high and low position further allowing the removal of the sleeve so as to obtain three water flows: - a low and peripheral flow in rain in the high position of the
sleeve which allows for example hand washing
for children or for dishes.

- an average flow form of a central jet and a peripheral rain
risk in the low position of the sleeve.

- a strong flow after removal of the sleeve which allows a function
operation in normal spray without reduction of the flow.

 In the latter case and in order to provide a regular flow, and straight so as not to splash, it will be inserted in the lower part of the conduit, a ball of diameter less than the inside diameter of said conduit so as to provide a 1 to 2 mm peripheral passage, ie a rotating propeller rotor, giving a helical component to the outgoing water jet in a very straight annular form.

 - Either the nozzle can include a swivel head with ball joint embedded between the part adapting to the tap and the conduit of the nozzle, and in this case include at the level of the ball a water inlet opening in said duct offset laterally instead of being axially disposed, so that when said duct is pivoted angularly, in a given direction, said opening is brought opposite the bearing of the ball joint, which is provided with a width sufficient to ensure cutting the flow of water passing through.

 The sleeve can be combined with a figurine such as an animal, character, fruit, object, so as to interest children by its playful aspect, thus giving it a dual use. Thus the device allows rapid and efficient adaptation. It allows to regulate three types of jet by a system of displacement of the nozzle and gives an aesthetic side due to the different shapes (animals, characters, fruits) interchangeable.

 The filter can consist of two spaced grids between which is trapped sand and charcoal and polyester wadding.

 With reference to these drawings, the device for regulating a jet of tap water is characterized by a plastic circular body (1) adaptable to a standard spout (2).

 On the underside is arranged a conduit (3) with ball joint (4) with pivoting head providing a jet.

 This jet is protected by a filter (5) defined by holes (6) arranged circularly.

 The pivoting head (4) is embedded in a part (7) provided in the lower part with a bowl (8) and which is intended to be fitted into a body (1).

 At the base of the conduit (3) and at the end is provided a "needle" or central patch (9) connected by legs or space arms (10) to the lower body (3.1) of the conduit (3) and which is castrated, or integral in one piece with a piece (3.2) higher and slightly larger in diameter, and which has a regulating function.

 On this duct is slidably mounted a sleeve (11) closed at the lower end by a plate (12) provided with perforations (13) outside the central area.

 Said plate (12) of the sleeve (11) is further perforated in the middle of a hole (14) corresponding to the dimension of the needle (9) and whose lateral sides are cut so as to define peripheral openings (15) for example giving this part a flower shape and allowing the pellet or needle (9) of the conduit to be fixed in the central part of the plate (12) perforated with holes (13).

 The sleeve (11) internally has a flare directed towards the plate (12) making it possible to define an enlarged flow rate in the manner of a sprinkler head relative to that leaving the duct.

 The hole (14) and the peripheral openings (15) can be closed by a grid or a perforated bottom (14.1). Said sleeve and said conduit comprise elastic retaining means (16) in the high and low position, further enabling the sleeve (11) to be removed.

 Said means can be constituted on the base (3.1) of the duct (3) of a bead (16.1) and on the sleeve of two corresponding annular grooves arranged in the middle and bottom part.

 The filter (5) is disposed between the part (7) and the bottom of the body (1) in which this part (7) is fitted and on which the conduit (3) is articulated by its ball joint (4).

 The body is provided in the upper part with an opening (17) extended downwards of flexible lips (18) arranged at an angle to ensure the elastic retention on the end of the spout (2). A plate (19) keeps the rubber head in order to fix it on the nozzle forming the nut at the end of the tap pipe.

 With reference to FIG. 7C, when the chest (9) of the conduit (3) is pushed inside the central hole (14) of the sleeve (11), the flow of water decreases, conversely, FIG. 7B, the water increases when said needle is released from the hole (14).

 The central hole (14) has the function of opening and closing a central water passage.

The different possibilities of jets are illustrated in FIGS. 7A to 7C - Figure 7C: small constant but enlarged flow (sleeve (11)
pushed up) due to the passage of water through the holes
(15) and (13).

- Figure 7B: constant medium flow (sleeve (11) pressed in
half) with water passing through the holes (14), (15) and
(13).

- Figure 7A: large constant flow of narrow section (after
traction on the sleeve and removal of the end of said
sleeve (1l) relative to the conduit (3)) the water comes out
directly through the lateral openings on the pad (9) of the
conduit (3).

 In addition, the jet breaker tip is characterized by its playful appearance. It is distinguished by different forms: animals (example: elephant illustrated in Figure 6B), fruits, characters. It therefore has a dual use.

 With reference to the three positions of use illustrated in FIG. 7, it can be seen that in the upper position of the sleeve (case C, the jet flows through the orifices (13) of the plate (12) as well as through the openings (15 ) lateral to the central orifice (14) giving a wide jet in rain with reduced flow.

 In the lower position of the sleeve where the patch (9) is released from the central hole (14) of the plate (12), case B, is added to the previous flow, a central main flow passing through the orifice (14).

 Finally, after removal of the sleeve (11), case A, the jet escapes directly to the periphery of the patch (9) of the conduit (3) with a dense jet of small diameter.

 Thus this device allows several types of flow diameters according to its use and achieves water savings thanks to its low flow rate obtained when the sleeve is fully inserted.

 Its playful form can encourage children to wash their hands and find pleasure in seeing water come out of a small animal, character, fruit or object. And with flow rates of different shapes. Indeed, few children want to wash their hands, especially before a meal.

 This nozzle breaker attempts to remedy this problem while allowing to choose its water flow. It therefore fulfills a double function.

 With reference to FIGS. 8 and 9, the adaptation means (1) on the tap consists alternatively of a body (1) formed by a nut part (20) provided internally at the end, in the upper part, with a clamping cone (21) of claws or elastic blades (22) curved internally at the end and fixed on the body (7) forming a central passage so as to ensure the clamping of said claws bearing on the upper edge of the end enlarged tap (2) when screwing the threaded part (20) of the body (1) on the threaded part (24) of the lower body (7).

 To ensure sealing, an elastic seal (25) is interposed between the body and the tap in the form of a sleeve with shoulder (25.1) intended to conform to the shape of the end of the tap and at the base of which is placed. the filter (5) and under the latter the retaining joint (26) of the pivot (4) of the conduit (3) on the bearing surface (3) of the part (7), in the chamber (23). The pivot (4) comprises, here an inlet (4A) of the conduit (3) offset to be closed by its covering by the bearing surface of the seal (26) when the conduit (3) is inclined on one side (Fig 10A) .

 The filter (5) is here produced in the form of two grids with spaced holes (6) connected by a peripheral cylindrical body by enclosing sand (5A), wooden sleeve (5B) and interchangeable polyester wadding making it possible to filter the 'water.

 In the duct (3) is preferably provided a ball (27) with a diameter slightly smaller than the inside diameter of the duct (3) so as to define a passage space of one to two millimeters on each side at the periphery to ensure laminar flow water so that it comes out around the central pellet (9) in the form of a straight jet and not enlarged and turbulent. This ball (27) is free to move in a cage defined in the upper part by three projecting parts (28) extending longitudinally and radially in the form of upper retaining spouts (29).

 In Figure 11 is illustrated a connection directly by screwing the body (20.A) on the threaded end of the valve (2). The body (20.A) is provided with a threaded connection means on a corresponding part of the valve: either a male threaded end (20.1) intended to be screwed onto the female threaded tap (30.1), or a female threaded end ( 20.2) screwed onto a male threaded end (30.2) of the tap (2), and externally threaded (20.5) to also receive a nut (34) threaded on the tap, with upper shoulder (20.6) in the form of a tightening cone bearing on the tap by means of an elastic retaining ring (20.8) or in two parts so as to ensure better resistance to pressure by the double fixing obtained.

 In this case, the internal body (7) receiving the ball joint (4) in combination with the seal (26) is simply fixed by screwing (7) in the body (20.A).

 Thus a good seal is obtained at the connection between the body (20.A) and the valve (2) because this connection must resist the pressure applied by water, in the case where the ball joint (4) acts as a flow control and is in an inclined position to shut off the flow.

 In Figures II and 14 is illustrated in a variant of the ball (27) provided in order to obtain a laminar flow, a propeller rotor (32) mounted rotating around a vertical axis at the inner base of the conduit (3) in order to give in addition a rotating movement to the flow then having annular sections as illustrated in FIG. 12, which makes it possible to limit the flow for the user in view of the external size of the jet, while the internal part of said jet is hollow.

 With reference to FIGS. 15 and 16, a slightly enlarged ferrule in the form of a collar (33) is provided on the duct (3) so that the duct (3) can be placed directly on the original filter grid or aerator support. of the tap (2) after removal of this grid.
