    PUSH NOZZLE ASSEMBLY
    BACKGROUND OF THE INVENTION
    AREAS OF THE INVENTION
    The present invention relates to a plunger nozzle assembly, and more particularly, to a plunger nozzle assembly for ejecting a liquid from a bottle.
    DESCRIPTION OF THE PRIOR ART The conventional plunger nozzle assembly is widely used in everyday life such as body wash, lotion, shampoo, laundry detergent, cleaning detergent, and plunger nozzle assembly is easily used by pushing the plunger nozzle assembly to obtain liquid from the bottle to which the plunger nozzle assembly is connected.
    Figure 1 shows a pusher nozzle assembly 100a including a pusher head 101a which is securely connected to a bottle 102a to prevent the liquid in the bottle 102a from leaking through the pusher head 101a. However, when the pusher head 101a is in the pusher position, the passage 104a in the pusher head 101a is open, and once the bottle 102a tilts, the liquid in the bottle 102a flows through the passage 104a or through other leaks. In addition, after releasing the pusher head 101a, there remains liquid residue in the outlet 105a of the pusher head 101a. Liquid residues flow by gravity through outlet 105a. The leakage problem occurs when transporting the plunger nozzle assemblies. When the bottle 102a tilts, the liquid contained in the bottle 102a easily flows into the cylinder 106a through the air release orifices, and easily accumulates at the piston 103a. This increases the risk of leakage.
    The present invention aims to provide a plunger nozzle assembly which eliminates the drawbacks mentioned above.

The advantage of the present invention is that by pushing the pusher head down to let the outer chamber come into contact with the locking member, the liquid in the cylinder is pushed out. By releasing the pusher head, the piston is moved backwards by the spring to create a suction force. Since the upper push rod and the suction valve are delayed for a while to be hermetically closed, the suction force draws the liquid remaining in the nozzle. When the second locking part of the external chamber locks with the fourth locking part of the locking element, since the piston rod and the piston head are integral with each other, and that the The lower end of the piston rod hermetically closes the piston so that the cylinder is completely sealed, and the liquid in the bottle cannot escape from the annular outlet. When the bottle tilts, the inlet valve prevents the liquid in the bottle from flowing into the cylinder and accumulating at the top of the piston head through the cylinder air release holes. This prevents leakage from the bottle. When the outer chamber is separated from the outer surface of the locking member and the pusher head is placed in its uppermost position, the upper pusher rod hermetically closes the suction valve to prevent leakage of liquid by the annular outlet.

The external chamber 102 comprises a second locking part 1021. The upper tube 81 comprises a third locking part 84 formed on its surface outside. The first and third locking parts 1011,84 are locked together. The locking element 7 comprises a fourth locking part 76 formed on its outer surface. The second and fourth locking parts 1021,76 are locked together.
    The push head 10 is locked with the upper push rod 8 by the connection between the first and the third locking part 1011,84. In the meantime, there is a space 104 formed between the upper end of the upper push rod 8 and the top of the internal chamber 101.
    In order to prevent the liquid contained in the bottle from flowing through the air release holes and flowing into the body 11 and accumulating at the upper end of the piston head 42, the assembly of plunger nozzle comprises an inlet valve 20 which is connected to the neck 73 of the locking element 7. More specifically, the inlet valve 20 comprises a first edge 201 formed in its inner periphery, and the neck 73 comprises a second edge 77 which is engaged by threading with the first edge 201.
    In use, the pusher head 10 is pushed to move the upper pusher rod 8 downward. In the stroke S1 of the space 104, the piston head 42 is stationary due to the friction with the internal wall of the body 11, so that the piston rod 41 does not move and that the annular outlet 911 opens gradually . When the race S1 is finished, the annular outlet 911 is completely open. The push head 10 is pushed continuously, the annular ring 83 is engaged with the first groove 411, and the push head 10 drives the upper push rod 8, the piston rod 41 and the suction valve 9 towards the bottom, until the external chamber 102 comes into contact with the mounting part 71. When the stroke S2 is finished, during this stroke, the piston head 42 compresses the interior space of the body 11. The check valve return 2 hermetically closes the inlet 16 following a pressure change, so that the liquid in the body 11 flows into the piston rod 41 and then flows to the nozzle 103 via the annular outlet 911. The liquid is finally expelled from the nozzle 103 as shown in Figures 6 to 8.
    When the pusher head 10 is released, the upper pusher rod 8 is moved upward by the spring 5, and the piston rod 41 and the piston head 42 are stationary due to friction with the internal wall of the body 11. The annular outlet 911 is gradually closed. The pusher head 10 is continuously moved upward by the upper pusher rod 8, and the upper pusher rod 8 drives the suction valve 9 and the piston rod 41 upwards. The liquid contained in the bottle is influenced by the suction force and begins to flow through the bearing 12 of the cylinder 1. The liquid pushes the non-return valve 2 and opens the inlet 16 and enters the lower part of the body 11, until the restriction part 421 of the piston head 42 comes into contact with the intake valve 20, to return to its initial position and be ready for the next push.
    When the pusher head 10 is released, the upper pusher rod 8 is moved upward by the spring 5, so that the piston rod 41 and the piston head 42 are stationary due to friction with the inner wall of the body 11. The annular outlet 911 is gradually closed. A suction force is formed in the space 104 to suck the liquid remaining in the nozzle 103. Consequently, the liquid will drip from the nozzle 103 due to gravity.
    By pushing the pusher head 10 and completing the strokes S1 and S2, the pusher head 10 continues to descend from the stroke S3. The second locking part 1021 of the external chamber 102 is locked with the fourth locking part 76 of the mounting part 71. The piston rod 41 is hermetically closed with the first bearing 31, so that the area located under the head piston 42 in the body 11 is hermetically closed. Even when the bottle tilts, the liquid in the bottle cannot leak through the inlet 16 of cylinder 1, as shown in Figure 9.
    When no force is applied to the pusher head 10, the annular outlet 911 is engaged with the wall defining the second groove 811 due to the spring 5, so that even when the bottle rocks or receives a force therein applied, the liquid in the bottle cannot leak through the annular outlet 911 of the suction valve 9.
    Although an embodiment has been described and illustrated in accordance with the present invention, it should be clear to those skilled in the art that other embodiments can be realized without departing from the scope of the present invention.
