Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a dispenser, and more particularly to a dispenser for adjusting rationing liquid.
  • 2. Description of Related Art
  • A conventional dispenser provides a double pistons structure for dispensing emulsion. The conventional dispenser includes a pump and an inductor received in the pump. The inductor has a top connected with a saddle head. The pump has an actuating groove defined therein for receiving the inductor. An elastomer is located in the actuating groove and connected with a bottom of the inductor. A valve is positioned in a bottom of the actuating groove. A piston set is assembled with the inductor. The piston set includes a first piston and a second piston connected with the first piston. The first piston includes a first tube for assembling with the inductor and a first flange for abutting against an inner periphery of the actuating groove. The second piston includes a second tube for assembling with the first piston and a second flange for abutting against the inner periphery of the actuating groove. The conventional dispenser is strengthened due to the double pistons structure for providing a long-wearing effect.
  • However, the conventional dispenser is not able to provide quantitatively rationing. The rationing of the conventional dispenser is decided by a pressure on the saddle head. This is inconvenient and is not able to provide a precise ration. When the pressure is over the expected value, the overflow dose will cause waste.
  • The present invention has arisen to obviate/mitigate the disadvantages of the conventional dispenser.

The base has a space defined therein and passing therethrough. The saddle head has a pathway defined therein and passing therethrough. The saddle head has a piston movably received in the space. The piston has an outer periphery abutting against an inner periphery of the space. The saddle head has a seat mounted in interior thereof for receiving the upper valve set. The saddle head has a skirt downwardly formed thereon. The base has a dove-tail flange annularly and outwardly extending therefrom. The skirt has a dove-tail flange annularly and inwardly extending therefrom for corresponding to the dove-tail flange of the base such that the dove-tail flange of the base and the dove-tail flange of the skirt are buckled to each other for preventing the saddle head detaching from the base. A spring is sleeved on the base for providing a restitution force. The upper valve set is mounted in the pathway and the lower valve set is mounted in the space in the base.

  • The base 1 has a tubular structure. The base 1 has a space 11 defined therein and passing therethrough. The base 1 has a lower end adapted to connect with the bottle and the lower valve set 4 is mounted in the lower end of the base 1 for communicating the bottle and the space 11.
  • The saddle head 2 has a pathway 25 defined therein and passing therethrough. The saddle head 2 has a piston 21 movably received in the space 11. The piston 21 has an outer periphery abutting against an inner periphery of the space 11. As shown in FIGS. 1 and 3, the saddle head 2 has a seat 22 mounted in interior thereof for receiving the upper valve set 3. The piston 21 is sleeved on a bottom end of the seat 22. The saddle head 2 has a skirt 23 downwardly formed thereon. The base 1 is located between the skirt 23 and the seat 22. The base 1 has a dove-tail flange 12 annularly and outwardly extending therefrom. The skirt 23 has a dove-tail flange 24 annularly and inwardly extending therefrom for corresponding to the dove-tail flange 12 of the base 1 such that the dove-tail flange 12 of the base 1 and the dove-tail flange 24 of the skirt 23 are buckled to each other for preventing the saddle head 2 detaching from the base 1. The saddle head 2 is slidably moved relative to the base 1. The piston 21 is able to compress and exhaust the air in the space 11. A spring 13 is sleeved on the base 1. The spring 13 has two ends respectively abutting against an inner periphery of the skirt 23 of the saddle head 2 and the base 1 for providing a restitution force.
  • As shown in FIGS. 1 and 3, the upper valve set 3 is mounted in the pathway 25 and the lower valve set 4 is mounted in the space 11 in the base 1. The upper valve set 3 has a same structure with the lower valve set 4. The upper valve set 3 has an outer ring 31 and an inner ring 32 received in the outer ring 31. The outer ring 31 of the upper valve set 3 has a plunger 311 disposed therein and a plurality of ribs 312 connected with the plunger 311 and an inner periphery of the outer ring 31. The inner ring 32 of the upper valve set 3 has a guiding path 321 defined therein. The plunger 311 of the outer ring 31 of the upper valve set 3 is able to selectively seal the guiding path 321 of the inner ring 32 of the upper valve set 3. The lower valve set 4 has an outer ring 41 and an inner ring 42 received in the outer ring 41 The outer ring 41 of the lower valve set 4 has a plunger 411 disposed therein and a plurality of ribs 412 connected with the plunger 411 and an inner periphery of the outer ring 41. The inner ring 42 of the lower valve set 4 has a guiding path 421 defined therein. The plunger 411 of the outer ring 41 of the lower valve set 4 is able to selectively seal the guiding path 421 of the inner ring 42 of the lower valve set 4. Precisely, each outer ring 31, 41 has three ribs 312, 412 equidistantly connected with the plunger 311, 411 and the inner periphery of the outer ring 31, 41. The ribs 312, 412 are provided for a restitution force to selectively seal the guiding path 321, 421 and positioning the plunger 311, 411 to partially insert into the guiding path 321, 421.
  • In the preferred embodiment of the present invention, each plunger 311, 411 has a hemispherical shaped structure for tightly plunging into the guiding path 321, 421. Each guiding path has a downwardly tapered structure. The part of each guiding path 321, 421 contacted with the corresponding plunger 311, 411 has a rounded structure for preventing the plunger 311, 411 from damaging.
  • With reference to FIGS. 3-4, when the saddle head 2 is pressed, the piston 21 presses the air in the space 11 to push the plunger 311 of the outer ring 31 of the upper valve set 3 such that the air exhausted from the pathway 25 in the saddle head 2. The plunger 411 of the outer ring 41 of the lower valve set 4 is pressed by the air to seal the guiding path 421 of the inner ring 42 of the lower valve set 4. When the saddle head 2 is released and returned due to the restitution force of the spring 13, the piston 21 of the upper valve set 3 is upwardly moved such that the air pressure in the space 11 is decreased to suck the outer ring 41 of the lower valve set 4 upwardly moved relative to the inner ring 42 and to suck the liquid in the bottle flowing into the space 11 via the guiding path 421 in the inner ring 42 of the lower valve set 4. In the meanwhile, the outer ring 31 of the upper valve set 3 is downwardly sucked by the air pressure in the space 11 such that the plunger 311 is sealed the guiding path 321 of the upper valve set 3. When the saddle head 2 is pressed again, the liquid in the space 11 is able to be drained from the pathway 25. When the saddle head 2 is released again, the liquid in the bottle is sucked into the space 11 again for providing rationing liquid.
  • As above described, the saddle head 2 is pressed in a first time, the air in the space 11 is exhausted outside. When the saddle head 2 is restored, the liquid in the bottle is drained into the space 11. Later, the space 11 is refilled with the liquid when the saddle head 2 is pressed in every time. The dose of the liquid drained from the saddle head 2 is the same with that refilled in the space 11. Therefore, the dose of the liquid is stable in every time for providing the rationing liquid.
  • With reference to FIG. 5, that shows a second embodiment of the dispenser for adjusting rationing liquid in accordance with the present invention. The elements and effects of the second embodiment which are the same with the first embodiment are not described, only the differences are described. The saddle head 2 has a flange 26 annularly and outwardly extending therefrom to form a flat plate. The two ends of the spring 13 are respectively abutted against the base 1 and the flange 26.
  • Although the invention has been explained in relations to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
