VALVE ASSEMBLY

Abstract

A valve assembly includes a connection portion and an outlet portion. The connection portion is adapted to be connected with a water dispenser or a pipe. A passage is defined axially through the connection portion and the outlet portion, and a transverse hole is defined transversely through the outlet portion and communicates with the passage. A control member is movably inserted in the transverse hole and includes at least one neck and a seal section. The seal section has a seal tube mounted thereto. When the control member moves in the transverse hole, and the neck is moved to be located corresponding to the passage, the passage is opened and water may flows through the passage. When the seal section is moved to be located corresponding to the passage, the passage is sealed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] Referring to FIGS. 1 to 6, the valve assembly 1 of the present invention is to be connected to a water dispenser or a water pipe, and comprises a connection portion 11 and an outlet portion 12 which is connected to the connection portion 11. The connection portion 11 protrudes from one end of the outlet portion 12 and includes outer threads 111 which are used to be connected to a water dispenser or a water pipe as desired. The outlet portion 12 is a bullet-shaped portion. A passage 13 is defined axially through the connection portion 11 and the outlet portion 12. A transverse hole 14 is defined transversely through the outlet portion 12 and communicating with the passage 13. The connection portion 11 is to be connected with a water dispenser or a water pipe so that water may flow through the passage 13. A control member 2 is an elongate member and movably inserted in the transverse hole 14. The control member 2 includes at least one neck 21 and a seal section 22, wherein the diameter of the at least one neck 21 is smaller than that of the control member 2. The seal section 22 has a seal tube 3 mounted thereto.

[0021] Specifically, the control member 2 comprises an elongate body 23 and a locking member 24, the body 23 has the at least one neck 21 and the seal section 22 formed thereto. Two flanges 25 are respectively located on two ends of the at least one neck 21, and the two flanges 25 respectively contact the first end of the seal section 22 and a first reduced section 26. The second end of the seal section 22 is axially connected with a second reduced section 27. Each of the first and second reduced sections 26, 27 has a seal ring 4 mounted thereto. The seal rings 4 contact the inner periphery of the transverse hole 14. A head 28 is formed on the first end of the body 23, and the locking member 24 is connected to the second end of the body 23. The head 28 and the locking member 24 are larger than the transverse hole 14 so that the control member 2 does not drop off from the transverse hole 14.

[0022] When the control member 2 moves in the transverse hole 14, and the neck 21 is moved to be located corresponding to the passage 13, because the diameter of the neck 21 is smaller than the body 23, so that the passage 13 is opened and water is able to flow through the passage 13 and the users get the water from the outlet portion 12 as shown in FIGS. 4 and 6. When the seal section 22 is moved to be located corresponding to the passage 13, because the seal tube 3 seals the transverse hole 14 and the passage 13, so that the passage 13 is sealed and the water does not flow out from the outlet portion 12 as shown in FIG. 3. The seal rings 4 prevent leakage between the inner periphery of the transverse hole 14 and the control member 2.

[0023] FIG. 7 shows that the valve assembly 1 of the present invention is directly connected with a water pipe which is connected with a conventional faucet. The user can keep the conventional lever at open position, and controls the water flow by operating the valve assembly 1 of the present invention. FIGS. 8 and 9 show that the valve assembly 1 of the present invention is an L-shaped valve, specifically, the outlet portion 12 is an L-shaped portion. The valve assembly 1 is connected to a wall.

[0024] FIGS. 10 to 13 show another embodiment of the control member 2, wherein the control member 2 comprises a body 23 and a locking member 24. The body 23 has two necks 21, and the seal section 22 is located between the two necks 21. Two flanges 25 are respectively located on two ends of the seal section 22, and the two flanges 25 respectively contact the two necks 21. A first reduced section 26 and a second reduced section 27 are respectively connected with the two necks 21. Each of the first and second reduced sections 26, 27 has a seal ring 4 mounted thereto. The seal rings 4 contact the inner periphery of the transverse hole 14. The seal tube 3 is mounted to the seal section 22. A head 28 is formed on the first end of the body 23, and the locking member 24 is connected to the second end of the body 23 and located close to the first reduced section 26 or the second reduced section 27. In this embodiment, the locking member 24 is located close to the second reduced section 27. In this embodiment, the users can operate the control member 2 in two opposite directions to get the water.

[0025] FIGS. 14 and 15 show that the connection portion 11 is defined in one end of the outlet portion 12 and includes inner threads 112 which are used to be connected to the water dispenser or the water pipe with a protruded threaded section.

[0026] 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.
