Description

[Detailed Description of the Invention] This invention relates to a faucet, and more specifically, to a faucet that can discharge or stop water by rotating a water discharge pipe attached to the faucet body.

Conventional faucets generally have a faucet body that has a valve seat inside, a spindle that moves the valve body toward and away from the valve seat from the outside, and a handle that rotates this spindle.By turning this handle, water is discharged. Alternatively, it was constructed so that the water could be stopped.

However, with this type of structure, if you cannot use both hands, the above operations cannot be performed, so in order to be able to operate the faucet even in such cases, a solenoid valve is used and a foot switch is used. There are faucets that open and close faucets to discharge water or stop water, but the volume of the faucet becomes large and the appearance is poor, and a power supply and switches are required to control the faucet. There is a large amount of space available, and the space is limited, making it unsuitable for kitchen faucets in vehicles or aircraft, where the space needs to be used for many purposes.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a pipe body that is equipped with a water inlet and a valve body and that communicates with the water supply pipe;
A spring that presses the valve body to close the water-conducting valve seat hole, and a cam that engages with the valve body to open and close the valve seat hole are provided in the faucet main body, and this faucet The present invention provides a faucet in which a protrusion provided at the base of a water discharge pipe attached to the main body is fitted into the cam so that water can be spouted or stopped by rotating the water discharge pipe.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is a cross-sectional view of the water faucet of this invention, where 1 is a rectangular faucet body, inside of which there is a tube body 12 with a smaller diameter than the inner diameter of the water inlet 11, and the water inlet as shown in Figure 3. 33 and a through hole 12A, a hemispherical valve body 13 is provided at the tip, a water spout 3 is provided on the water spout 14 side, and a screw 16 for screwing the joint body is provided on the inner surface on the water supply port side. A screw 17 for screwing into a cap nut 2 is carved on the outer periphery of the water discharge side, and a flange 18 is provided protruding from the outer periphery of the faucet body at approximately the center thereof. 3 is a water discharge pipe, and the base of the pipe body 31 is provided with a square projection 36 that fits into the oval cam 8 that engages with the valve body 13.
A plurality of water inlet ports 33 communicating with the inside of the pipe are opened near the valve body, and a collar 34 is provided on the outer periphery, and the pipe body 31 has a shape of approximately U for convenience of use.
It is bent into a letter shape. Reference numeral 4 denotes a joint body, in which a screw 42 is carved on the outer periphery of one large diameter portion 41 to be screwed into the screw 16 of the faucet main body 1, a collar 43 is provided at the open end, and a small diameter portion 44 is provided. A water supply pipe insertion opening 45 into which the water supply pipe 5 is fitted is formed on the side.
Note that 15 and 21 in the figure are O-rings for preventing water leakage.

As shown in FIGS. 1 to 3, each of the above-mentioned components is assembled by attaching the faucet body 1 to a mounting hole 61 formed in the support plate 6 and having a slightly larger diameter than the outside diameter of the faucet body, so that the flange 18 is inserted from the water inlet side. Insert the support plate until it makes contact with one side of the support plate, screw the female screw 39 onto the screw 16 on the water inlet side that comes out on the other side, so that the support plate 6 is held between the flange 18, and insert it on the small diameter part 44 side. The water supply pipe 5 is inserted and fixed into the inlet 45 using an adhesive. Next, attach the bag nut 2 to the spout 35.
Connect the spout pipe 3 installed from the side to the spout 1 of the faucet body 1.
After the square protrusion 36 is fitted into the square hole 37 of the cam 8, the cap nut 2 is screwed onto the spout to complete the installation.

When in use, when the water discharge pipe 3 faces to the left when viewed from the front of the sink 7 as shown in Fig. 4, the valve seat hole 13 of the valve body 13 should be opened as shown in Figs. 2b and d.
The valve body 13 enters into A due to the elasticity of its spring 9 and closes the valve seat hole, resulting in a water stop state. When the water discharge pipe 3 is rotated 90 degrees from this state as shown in FIG. 5, the state shown in FIG. , c, the cam 8 rotates, the valve body 13 is pulled away from the valve seat hole 13A, and the water from the water supply pipe 5 passes through the valve 12 and the pressure reduction chamber 19 as shown by the arrow, and then enters the water supply hole 33. Water is discharged into the sink 71 from the water spout 35 through the body 31.

In the case of water outage, the water can be stopped by performing the opposite operation to the water discharging operation. Therefore, as shown in FIGS. 4 to 6, when the water is stopped, the water discharge pipe 3 is positioned parallel to the opposite edge of the sink 71, so that the space above the sink can be used more widely. In the figure, 10 is a screw cap, and 10A is a central bearing portion of the cam 8.

As described above, this invention includes a pipe body that is equipped with a water inlet and a valve body and communicates with a water supply pipe, a spring that presses the valve body to close the valve seat hole for water conduction, and the valve body. A cam that is to be engaged with to open and close the valve seat hole is provided in the faucet body, and a protrusion provided at the base of the water discharge pipe attached to the faucet body is fitted into the cam to open and close the water discharge pipe. Since water can be spouted or stopped by rotating the valve, the water pressure of the water supply pipe acts on the valve body in the direction of closing the valve, so the spring for pressing the valve body does not need to be strong, so water can be spouted or stopped. It is easy to operate and has the advantage of allowing more space to be used when the water discharge pipe is stopped rotating.
