- the elastic element is formed by a piece of elastic porous foam disposed downstream of the air outlet opening, with respect to a flow towards the expulsion orifice to achieve the stirring of air and foaming liquid.
- the sealing check valve comprises a deformable portion to ensure a tight closure of the liquid outlet opening.
- the foaming liquid supply tank of variable capacity, comprises a movable piston sliding sealingly abutting against an inner wall of the tank, the movable piston being arranged vis-à-vis the opening inlet of the liquid chamber.
- the air chamber comprises two cylindrical walls centered around the same axis and joining by the bottom of the air chamber, a piston, in which are formed the inlet for the air supply and the air outlet opening, closing the air chamber and sliding along the axis of the air chamber, the piston of the air chamber being pushed towards the bottom of the air chamber by the action of the user on a projecting portion of the piston or the piston being remote from the bottom of the chamber by the action of the return spring, the return spring being arranged in the air chamber, resting on the bottom .
- the liquid chamber is disposed in the center of the air chamber, the liquid chamber comprising a cylinder of the same axis as the air chamber, closed by a piston, in which the opening of liquid outlet, the piston of the liquid chamber being integral with the piston of the air chamber, the inlet opening of the liquid chamber being formed in the bottom of the cylinder of the liquid chamber.

- the foam producing device as shown in FIG. 1, comprises a reservoir (100) containing foaming liquid.
- the foam production device is portable by hand.
- the reservoir (100) is made, for example, inside a cylinder (101).
- the inner wall of the cylinder (101) is of round or oval cross section.
- a piston (102) of the same cross section is movable in the cylinder (101) and rests on the inner wall of the cylinder (101) sealingly.
- the reservoir comprises an opening (103), in a nonlimiting manner, vis-à-vis the piston (102), through which the liquid exits the reservoir (100).
- the liquid outlet through the opening (103) causes a translation of the piston (102) and a decrease in the volume of the reservoir (100).
- the piston (102) movable partially delimiting the reservoir (100) allows to have an adaptable capacity of the reservoir (100), the capacity being identical to the volume of foaming liquid contained. The more the foaming liquid is sucked through the opening (103), the more the piston (102) approaches the bottom of the cylinder to reduce the capacity of the reservoir (100).
- the patent US 5,152,434 describes for example a pump not suitable for the production of foam, equipped with a reservoir of this type.
- the piston (102) comprises on one face opposite the tank, a fastener (104) accessible from the outside of the foam producing device, for gripping the piston (102) during disassembly to fill the tank (100).
- the tank (100) As the flow of fluid passing through the opening (103) of the tank (100) is made in the direction out of the tank (100), the tank (100), initially completely filled with a determined foaming liquid, contains only this liquid .
- the tank does not contain, for example, no air.
- the opening of the reservoir (100) is always fed with foaming liquid until the reservoir (100) has reached its minimum capacity, when the piston (102) advances to an abutment position, for example against the opening (103).
- the inlet opening of the chamber (2) of liquid coincides with the opening of the reservoir.
- the liquid chamber (2) is formed inside a cylinder (23) of the liquid chamber and is closed by a piston (24) sliding in the cylinder (23).
- the piston (24) movable in translation in the cylinder (23) of the liquid chamber, is pressed against the inner wall of the cylinder (23) sealingly.
- a non-return valve (22) disposed at the inlet (103) of the chamber (2) of liquid prevents a flow of the liquid returning to the reservoir (100).
- the non-return valve disposed at the the inlet of the liquid chamber is, for example, a ball (22) resting against a frustoconical wall (21) widening towards the ball and forming the edges of the opening (103) of the inlet of the chamber ( 2) liquid.
- the valve disposed at the outlet of the chamber (2) of liquid comprises elastic means for holding in the closed position, making it possible to close sealing the outlet opening (25) of the chamber (2) of liquid until the pressure in the chamber (2) of liquid is insufficient so that the liquid contained in the chamber (2) of liquid does not push the valve of seal.
- the sealing valve as represented in FIG. 2, is produced, in a nonlimiting manner, by a ball (412) pushed by a resilient element (413, 415) against a frustoconical wall (411) widening toward the ball (412).
- the ball (412) is for example made of plastic or glass, the wall (411) being, for example made of plastic.
- the frustoconical wall (411) has a hardness determined to deform in contact with the ball (412).
- the element (413, 415) elastic is for example in abutment against a ring (414) fixed support relative to the chamber (4) mixing.
- the elastic element is made, without limitation, by an elastic porous foam (413) exerting a holding force of the ball (412) against the frustoconical wall.
- the porous foam (413) also mixes the liquid with the air to produce foam.
- the elastic element is a spring (415) resting on the support ring (414) and against the ball (412), a net (42) or a porous foam being disposed downstream of the ring (414), relative to the direction (5000) of expulsion, for stirring the foaming liquid with air and producing foam (51).
- the spring (415) is for example metal or plastic.
- the sealing valve comprises a boss (416) held in abutment against the outlet (25) of the chamber (2) of liquid, by elastic arms (417). .
- the boss (416) is elastic to plug the outlet opening (25) of the chamber (2) of liquid by deforming when inserted into the outlet opening (25).
- a chamber (3) of air is for example made around the chamber (2) of liquid, as shown in Figure 1.
- the chamber (3) of air is formed by a cylinder (31) in which slides sealing a piston (32).
- the cylinder (31) of the air chamber (3) is, for example, arranged coaxially and around the cylinder (23) of the liquid chamber.
- the piston (32) of the air chamber (3) is connected to the piston (24) of the chamber (2) of liquid.
- a flow of air (3002) is expelled from the air chamber (3) through the outlet (s) (34) of the air chamber to the mixing chamber (4).
- the piston (32) of the chamber (3) of air being connected to the piston (24) of the chamber (2) of liquid, an overpressure is created at the same time in the chamber (3) of air and in the chamber (2) liquid, when the user exerts pressure for example on the head (61) of expulsion.
- the expulsion head (61) is for example mounted in abutment on a piece forming the piston of the liquid chamber and the piston of the air chamber.
- the diameter of the opening of the outlet (34) of the chamber (3) of air is, for example, sized relative to the outlet diameter (25) of the chamber (2) of liquid to achieve a mixture of air and foaming liquid product in a proportion determined.
- the air chamber (3) is arranged adjacent to the mixing chamber (4), the outlet (34) of the air chamber (3) opening directly into the mixing chamber (4), as shown in Figure 2.
- the outlet (34) of the air chamber communicates with a duct (35) leading to the mixing chamber (4).
- the spring (39) disposed in the chamber (3) of air is protected against possible corrosive attacks by the foaming liquid.
- a depression is then created in the air chamber and a current (3001) of incoming air pushes back the check valve (s) (36) of the air inlet (s) (33) of the air chamber.
- the air chamber then fills with air from outside the foam producing device.
- the communication between the air chamber and the mixing chamber is left free.
- the air inlet (s) (33) of the air chamber (3) have in fact a cross section sufficient to supply the air chamber with a flow of air coming from the outside. Air can also pass through the orifice (5) and the mixing chamber (4) to enter the air chamber through the outlet (s) (34), although in practice this inflow of air is negligible.
- a suction (3001) of air is created in the chamber (3) of air at the same time as a suction (1000) of foaming liquid in the chamber (2) of liquid, as shown in Figure 5.
- the expulsion of foaming liquid and air into the mixing chamber (4) allows stirring of the foaming liquid by the mixing element (42), as shown in FIG.
- the foam produced by the stirring element (413) is directed in an expulsion conduit (6) to an orifice (5) for expulsion of the foam, or as shown in Figure 3, the foam produced by the brewing element (42) exits directly through the orifice (5) expulsion.
- the sealing valve at the outlet of the chamber (2) of liquid, prevents leakage in case of overturning.
- this sealing valve makes it possible to keep the foaming liquid safe from the air, certain product requiring to be kept out of the air.
- the expulsion orifice (5) is arranged against the stirring element (42), as shown in FIG. 3, to avoid storing foam in an expulsion duct (6) or to be able to rinse the mixing chamber (4) after use.
- foaming liquid When the foam-producing device is activated, foaming liquid will always be present at the inlet (103) of the liquid chamber (2), regardless of the inclination of the foam-producing device.
- the reservoir of course provides foaming liquid in all positions, as long as the reservoir (100) is not emptied.
- the sealing valve plugging the outlet opening (25) of the liquid chamber, prevents the defusing of the chamber (2) of liquid in case of reversal.
- the overpressure in the liquid chamber allows the expulsion (200) of foaming liquid in the chamber (4) of mixing, the elastic element (415) of the sealing valve then bringing the latter into its closed position, even if the user keeps the head of the foam production device in the depressed position.
