DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel single lever type faucet which discharges water by rotating an operation lever in a vertical direction.

[0002]

2. Description of the Related Art Conventionally, as a faucet for spouting tap water or the like, a universal faucet with a rotary operation handle is generally used, for example, as shown in FIG. In the figure, reference numeral 1a denotes a faucet main body made of a bronze casting, which includes a front-rear water supply unit 2 provided on the rear side, a vertical mounting unit 3 provided on the upper surface of the central part, and a downwardly curved front side. A water supply channel 5 is formed in the water supply unit 2, and a water discharge channel 8 is formed from a mounting port 6 of the mounting unit 3 to a water discharge port 7 of the water discharging unit 4, Communication hole 1 formed in partition wall 9 that separates water supply channel 5 and water discharge channel 8
By 0, the water supply channel 5 and the water discharge channel 8 communicate.

[0003] Reference numeral 11 denotes a vertical plug which is inserted into the water discharge passage 8 of the mounting portion 3, and an upper portion protrudes upward from the mounting opening 6. Reference numerals 12 and 13 denote screw holes and insertion holes formed on the upper and lower sides of the stopper rod 11, respectively.
A disc-shaped pedestal 14 is fixed to the rod 13a, and a packing 15 made of synthetic rubber is provided on the lower surface of the pedestal 14 so that the water-stopper is provided on the periphery of the communication hole 10 when water is stopped. It comes into pressure contact with the protruding annular valve seat 16. Reference numeral 17 denotes a screw portion formed on the stopper rod 11, which is screwed to the inner surface of the mounting portion 3 to close the water discharge passage 8.

Reference numeral 18 denotes a holding member through which the upper portion of the stopper rod 11 is inserted. A triangular packing 19 is provided inside the holding member, and the packing 19 is supported in the holding member 18 by a receiving plate 20.

5, a water faucet main body 1b including a holding metal fitting 18 and an operation handle 21 is attached to the faucet main body 1a.

When the operating handle 21 is rotated counterclockwise to loosen it, the plug bar 11 moves upward, the packing 15 is pushed up by water pressure and detaches from the valve seat 16, and the faucet body 1 is released.
The water flows from the water supply channel 5 a to the water discharge channel 8 through the communication hole 10, and is discharged from the water discharge port 7 of the water discharge channel 8. Further, the water discharge flow rate can be appropriately adjusted by rotating the operation handle 21.

[0006]

In the case of the conventional water faucet, since the flow rate is adjusted by rotating the operation handle 21, the operation is complicated and the operation of rotating the operation handle 21 is repeated. As a result, there is a problem that the packing 15 is deteriorated.

Further, when the packing 15 is deteriorated, even if the operation handle 21 is tightened, the water cannot be completely stopped, and water leakage occurs, and it is necessary to tightly tighten the operation handle 21 when stopping the water. There is.

The present invention has been made in consideration of the above points, and has as its object the purpose of being able to adjust the flow rate and stop water with a simple operation, eliminate wasteful water discharge, and easily replace the packing. It is to provide a single lever type faucet that can be used.
