Abstract

A liquid sucking and dispensing device includes a body having a passage and an air inlet and an air outlet are respectively located one two ends of the body. A first valve is engaged with the passage at a mediate section of the passage and a second valve is engaged with the passage at a second end of the body. An opening is defined radially through the body and communicates with the passage and an interior of a container. When the second valve closes the passage, pressurized air enters the container to push liquid in the container out from the container.

    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 2, the A liquid sucking and dispensing [0016] device 20 of the present invention comprises a body 21 having a passage 22 defined longitudinally therethrough and an air inlet 24 is defined in a first end of the body 21 and an air outlet 25 is defined in a second end of the body 21. The passage 22 has a narrow section 23 so as to increase the pressure in the passage 22. A first valve 30 is transversely movably engaged with the passage 22 and cooperated with a spring so that the first valve 30 can be moved in the body 21. The first valve 30 is located between the air inlet 24 and the narrow section 23. A handle 10 is pivotally connected to the body 21 and the first valve 30 has a section extending radially from the body 21 so that the section of the first valve 30 can be pushed by the handle 10 to open the passage 22 as shown in FIG. 2. A second valve 40 is transversely rotatably engaged with a hole 27 in the body 21 and the passage 22 and located between the narrow section 23 and the air outlet 24. Further referring to FIGS. 3 and 4, the second valve 40 includes a cylindrical body 41 and a hole 42 is defined radially through the cylindrical body 41. The cylindrical body 41 is rotated to an open position as shown in FIG. 3 to communicate the hole 42 with the passage 22. An opening 26 is defined radially through the body 21 and communicates with the passage 22 and is located between the narrow section 23 and the second valve 40. A pipe can be connected to the opening 26 and is inserted in a container (not shown).
  • When the [0017] first valve 30 and the second valve 40 are both in open position, the pressurized air enters the passage 22 from the air inlet 24 and leaves from the air outlet 25. In the meanwhile, the air in the container will be sucked out from the container so that liquid outside of the container will be sucked into the container from other pipe (not shown).
  • FIGS. [0018] 5 to 7 show another embodiment of the device 20′ connected to a handle 212′ on a cover 211′ threadedly mounted to a container 60′. A fitting 51′ and a pipe 50 extend through the cover 211′ and insert into the container 60′. The first valve 30′ is connected to the body 20′ from an underside of the cover 211′ and communicates with the passage 22′. The second valve 40′ is linearly connected to the second end of the body in the handle 212′. A hole 25′ is defined radially through the cover 211′ and communicates with the passage 22′ and the hole 25′ communicates with an interior of the container 60′. The second valve 40′ includes a sleeve 41′ mounted to the second end of the body 21 and a movable member 45′ movably received in an end hole 42′ of the sleeve 41′. The sleeve 41′ includes a plurality of slots 44′ and a tubular portion 43′ extends inward from an end of the sleeve 41′ so that the movable member 45′ extends through and is guided by the tubular portion 43′. The movable member 45′ has a tapered tip 451 ′ which movably seals the tapered shaped air outlet 24′ of the passage 22′. As shown in FIG. 8 the movable member 45′ is moved away from the cover 211′ to open the outlet 24′. Pressurized air can release from the slots 44′ in the sleeve 41′.
  • FIG. 9 shows that the [0019] device 20′ can be connected with a large container 60″ wherein a long pipe 50″ communicates with the cover 211″ and a distal end of the long pipe 50″ is an inclined end so that the liquid can be sucked out from the container 60″ by the device 20′.
  • FIG. 10 shows that a [0020] liquid gas tank 70 us cooperated with the device and the air outlet 240 is radially defined through the end of the body. The second valve 400 is threadedly connected to the body and movably seals the air outlet 240.
  • While we have shown and described various embodiments 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 and spirit of the present invention. [0021]
