DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. I and 2, the spray head assembly 10 of the present invention is designed to suck liquid in a bottle and eject the liquid from the spray head assembly 10. The spray head assembly 10 comprises a head I having a nozzle 11 connected thereto and an extension tube 12 is connected to the head 1. A main tube 2 has a mount tube 21 on a first end thereof and the mount tube 21 is inserted into the extension tube 12. A tubular portion 22 formed on a second end of the main tube 2 and a flange 23 extends from an outer periphery of the main tube 2 and is located between the mount tube 21 and the tubular portion 22. A link 3 is a hollow tube and has an elongate part 31 on a first end thereof and the elongate part 31 extends through the main tube 2. Multiple grooves 311 are defined axially in an outer surface of the link 3 and an annular seal end 32 is formed on a second end of the link 3. A piston 4 is movably mounted to the link 3 and has a first opening 41 and a second opening 42 defined in two ends thereof. The piston 4 is reciprocally moved to contact the seal end 32 or to be separated from the seal end 32. A reception member 5 is mounted to the piston 4 and includes a first section 51 and a second section 52. A diameter of the first section 51 is larger than that of the second section, and a shoulder 53 is formed on an outer surface of the reception member 5 and located between the first and second sections 51, 52. An inlet 521 is defined in the second section 52 and a chamber 522 is defined between the inlet 521 and the piston 4. A one-way valve 54 is located at the inlet 521. In this embodiment, the one-way valve 54 is a bead. The second section 52 of the reception member 5 has a reception port 523 defined therein. The reception port 523 is connected with a suction tube 55 which is inserted into the bottle 20. A mount piece 6 is connected to the reception member 5 and has a through hole 61 through which the main tube 2 extends. An extension portion 62 extends from the mount piece 6 and the main tube 2 is stopped when the extension portion 62 contacts the flange 23 of the main tube 2. A spring 7 is mounted to the main tube 2 and biased between the flange 23 and the shoulder 53 of the reception member 5 so as to provide a force to the main tube 2. A positioning member 9 is used to connect the spray head assembly to a botfle 20.
The piston 4 is movably mounted to the link 3 and the two parts are connected to each other to be a closed status or to be separated from each other to form an opened status. A gap 8 is defined between the second section 52 of the reception member 5 and the seal end 32 when in the opened status. Liquid in the bottle 20 flows into the head I via the gap 8 and the grooves 311 and is ejected from the nozzle 11 by pressing the head 1.
A side hole 524 is defined through a wall of the second section 52 of the reception member 5 and communicates with outside so as to balance pressure in the reception member 5 after the head I is pressed. When the piston 4 moves the a lower portion of the reception member 5, the interior of the reception member 5 and outside of the reception member 5 are in communication with each other so that the pressure in the reception member and the pressure outside of the reception member 5 is balanced. An engaging portion 511 is located in the first section 51 of the reception member 5 and the mount piece 6 has a connection portion 621 on an outside of the extension portion 62 so as to be engaged with the engaging portion 511 to connect the reception memberS and the mount piece 6.
As shown in Fig. 3, when the head I is pressed, the main tube 2 is lowered and the link 3 and the piston are lowered in sequence. In the meanwhile, the piston 4 gradually reduces the volume of the chamber 522 of the reception member 5 so that the hydraulic pressure increases to move the one-way valve 54 to seal the inlet 521 of the reception member 5 to seal the chamber 522. The second opening 42 of the piston 4 is then opened to form the gap 8. The liquid is ejected from the nozzle 11 by the high pressure via the grooves 311 and the main tube 2.
As shown in Fig. 4, when the head 1 is released, the main tube 2 and the head I move back by the force of the spring 7, and the link 3 is moved upward so as to seal the gap 8 between the seal end 32 and the second opening 42. The spring 7 continuously pushes upward to move the piston 4 upward to increase the volume of the chamber 522 and a low pressure is formed in the chamber 522. The low pressure makes the inlet 521 and the liquid in the bottle 20 suddenly moves upward and flows into the chamber 522 via the suction tube 55 and the inlet 5211 and ready for the next ejection.
It is noted that when the main tube 2 moves back, the extension portion 62 of the mount piece 6 contacts the flange 23 of the main tube 2.
Accordingly, by control the length of the extension portion 62 of the mount piece 6, the travel distance of the main tube 2 can be adjusted to control the volume of each spray.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
