    [0005] With reference to FIG. 1, the spray head assembly 100 of the present invention comprises a pusher head 1, a support 2, a member provided with grids 3, a valve 4, a first piston 5, a connecting rod 6, a main part 7, an elastic member 8, a limiting member 9, a second piston 10, a valve 11, a cylinder 12 and a seal 13. The pusher head 1 comprises an outlet 101 from which the foam is ejected. The member provided with grids 3 is arranged in the pusher head 1 and comprises a tube 33, a first gate 31 and a second gate 32. The liquid and the air can be fully mixed when passing through the first and second grids 31, 32.
    [0006] Referring to Figure 5, the valve 4 comprises at a first end an air inlet 401 and an air passage 402, and the second end of the valve 4 is connected to the member provided with grids 3 and at the 1. With reference to FIG. 6, the first piston 5 is in the form of a ring and is connected to the valve 4. The first piston 5 comprises a sealing element 501, an orifice 502 and a wall 503 which is movable to close or open the air inlet 401. With reference to FIG. 7, the main part 7 is in the form of a hollow tube and comprises an air chamber 701 and an inclined wall 702. The sealing member 501 is in contact with the air chamber 701 and is movable to open or close the air chamber 701. The main portion 7 includes an end resiliently connected to the outer wall of the air chamber 701. the valve 4. With reference to FIGS. 1 and 2, the connecting rod 6 extends through the main part 7 and comprises a conical head 61, a body 62 and a pointed end 63. A neck 64 is formed between the body 62 and the pointed end 63. The outer wall of the conical head 61 is in contact with the inner surface of the inclined wall 702 and an outlet passage 601 is defined between the outer wall of the conical head 61 and the inner surface of the inclined wall 702. A mixing chamber 605 is defined within the interior of the conical head 61. The second piston 10 is in the form of a ring and is connected to the connecting rod 6 and the main part 7. The cylinder 12 is connected to the support 2 and comprises an air chamber 1201 and a liquid chamber 1202. The limiting element 9 is arranged between the air chamber 1201 and the liquid chamber 1202. Each of the air chambers 1201 and the liquid chamber 1202 is in the form of a closed chamber . The first piston 5 is movable back and forth in the air chamber 1201, and the second piston 10 is movable back and forth in the liquid chamber 1202. In this embodiment, the air chamber 1201 is larger than the liquid chamber 1202. The first piston 5 is larger than the second piston 10.
    [0007] The support 2 comprises a thread 21 defined internally so as to be connected to a bottle. A seal 13 is arranged in the support 2 to seal the opening of the bottle. The elastic member 8 is mounted outside the main part 7 and is in contact with the limiting element 9. The valve 11 is engaged in the opening 1203 of the cylinder 12. A first space 602 is defined between the body 62 of the connecting rod 6 and the main part 7. A second space 603 is defined between the neck 64 of the connecting rod 6 and the second piston 10. The pointed end 63 of the connecting rod 6 protrudes from the second piston 10 and has a shoulder 604 which is in resilient contact with the abutment 1002 of the second piston 10. An inlet passage 1001 is defined between the shoulder 604 and the abutment 1002. The flap 11 is arranged in the opening 1203 of the cylinder 12. The liquid chamber 1202 comprises a suction passage 1204 intended to receive the valve 11. With reference to FIG. 3, when pressure is exerted on the pusher head 1 , said push head 1 is moved to the first lower position S1, the valve 4, the main part 7, and the connecting rod 6 are moved simultaneously, and the first and second pistons 5, 10 remain stationary due to the friction with the cylinder 12. The shoulder 604 is 20 away from the stop 1002 of the second piston 10, when the main part 7 moves downwards, so that the inlet passage 1001 is open. The connecting rod 6 is moved upwards due to the pressure of the liquid chamber 1202 of the cylinder 12, so that the conical head 61 is moved away from the inclined wall 702 to open the outlet passage 601. on the other hand, when the valve 4 is moved to the first lower position S1, the first piston 5 remains stationary so that the air inlet 401 is gradually closed by the wall 503, and the sealing element 501 opens gradually the air chamber 701. With reference to FIG. 4, when the pusher head 1 is moved to the second low position S2, the second piston 10 pushes the liquid into the liquid chamber 1202, so that the liquid passes through the inlet passage 1001, the second space 603, the first space 602, the outlet passage 601 and enters the mixing chamber 605. The air contained in the air chamber 1201 is pushed by the first piston 5 and passes through the room of ai r 701, the air passage 402 and enters the mixing chamber 605 to be mixed with the liquid. The mixture passes the first and second grids 31, 32 to form, as a combination, foam that is ejected through the outlet 101 of the pusher head 1.
    [0008] When the pusher head 1 is released, it is pushed upward from the second low position S2 to the first lower position S1. The main part 7, the valve 4, and the connecting rod 6 are moved simultaneously upwards, and the first and second pistons 5, 10 remain immobile because of the friction with the cylinder 12. The connecting rod 6 is moved upwards through the main part 7, so that the outlet passage 601 and the inlet passage 1001 are progressively closed. The valve 4 is moved with the main part 7, the first piston 5 remains stationary and the air inlet 401 is opened gradually. The sealing element 501 gradually closes the air chamber 701.
    [0009] Simultaneously with the upward movement of the main part 7 and the connecting rod 6, when they reach the initial position S, the first and second pistons 5, 10 are displaced upwards to increase the volume of the chamber. air 1201 and the liquid chamber 1202. Outside air is sucked into the air chamber 1201 through the air inlet 401 and the orifice 502. The liquid in the vial (not shown) repels the valve 11 and enters the liquid chamber 1202 through the opening 1203 so as to be ready for the next action. It should be noted that the first gate 31 and / or the second gate 32 are made by injection molding. Therefore, they are secured by engagement with both ends of the tube 33. In order to obtain a fine foam, the openings of the first grid 31 and / or the second grid 32 are polygonal openings. Alternatively, the apertures of the first grid 31 are greater than or equal to those of the second grid 32. The liquid and the air pass through the larger openings of the first grid 31 and generate foam which passes through the smaller openings of the second grid 32 to create a thin foam. In this embodiment, the valve 11 is a ball that moves upward to open the opening 1203, and moves down to close the opening 1203.
    [0010] In addition, the opening 1203 of the cylinder 12 is connected to a pipe 14 so as to suck the liquid into a vial (not shown). On the other hand, the elastic member 8 is mounted outside the main part 7, and when the inlet passage 1001 is open, the liquid passes through the second space 603, the first space 602, the exit passage 601, and enters the mixing chamber 605 to prevent the elastic member 8 is in contact with the liquid, so that the elastic member 8 is protected from rust, and the liquid is not contaminated by the Elastic member 8. Although an embodiment according to the present invention has been illustrated and described, it will be apparent to those skilled in the art that other embodiments may be made without departing from the scope of the present invention. .
