Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a discharge port structure forming the tip of a water discharge pipe of a single faucet, a mixed faucet, or the like.

(Prior art and its problems) Conventionally, a faucet fitting such as a single faucet or a mixed faucet is provided with a water discharge pipe in a protruding and rotatable manner, and hot water is discharged from the tip of the water faucet. However, for example, when hot water is discharged from the outlet at the tip of a mixing faucet, it may be necessary to rotate the tip of the discharge pipe to supply hot water to a different location. In such a case, it is necessary to hold the tip of the water pipe in your hand and rotate the water pipe horizontally; at this time, the tip of the water pipe is hot and there is a risk of burns. Yes, I had a problem using it. Also, in the past, the tip of the water discharge pipe was simply L.
Because of the bent shape, the design of the faucet fittings was monotonous, and there were problems with the design of the tip of the water pipe.

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and the tip of the water faucet pipe of the faucet fitting has a safe structure that will not cause burns, etc. Furthermore, the purpose is to provide a discharge outlet structure that can improve the design of the dispensing pipe tip. A convex portion 1b with a ring groove 1c formed on the outer periphery is protrudingly provided, and a water guide chamber 1f coaxially communicating with the water passage R in the water discharge pipe T is formed inside.
The inner tube 1 has an opening 1g that opens perpendicularly to the flow direction in the water guide chamber 1f, and a fitting hole 2a into which the convex portion 1b of the inner tube 1 can fit. The opening 1 is fixed to the outer periphery in a cover-like manner.
a heat insulating cap 2 made of a heat insulating material with a discharge part 1b protrudingly aligned with the convex part 1b; a snap ring 3 that is fitted into a ring groove 1c on the outer periphery of the convex part 1b to prevent the heat insulating cap 2 from slipping out; A threaded portion 2 formed on the outer periphery of the fitting hole 2a of the cap 2
e, and a cover 4 is attached coaxially to the end of the heat insulating cap 2 to cover the periphery of the snap ring 3.

(Function) An inner pipe is fixed to the distal end of the water faucet fitting in a continuous manner, and the outer periphery of this inner pipe is covered with a heat insulating cap. The heat insulating cap does not become hot even when hot water is introduced into the tip, so you can easily hold the tip of the spout pipe in your hand and rotate the spout pipe to the appropriate position, preventing burns even when hot water is discharged. The water discharge pipe can be easily rotated without incurring damage. Furthermore, by appropriately changing the design of the heat insulating cap and cover, it is possible to improve the design of the distal end of the water discharge pipe.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a sectional view of the outlet structure of this example, and FIG. 2 shows a schematic diagram of the faucet fitting.

In the figure, a water discharge pipe T is rotatably attached to the faucet fitting M via a joint part J in a protruding manner, and hot water can be supplied into the water discharge pipe T by appropriately rotating the handle H. ing. Water pipe T
As shown in Fig. 1, the distal end has a discharge port structure mainly composed of an inner tube 1, an insulating cap 2, and a cover 4, and the inner tube 1 is made of metal. A stepped portion 1a is formed at the right end in the figure, and the tip of the water discharge pipe T is fitted into this stepped portion 1a and fixed by means such as welding or adhesion. Further, the other end of the inner tube 1 has a protruding portion 1b.
are integrally formed, and a ring groove 1c is formed on the outer periphery of the tip of the convex portion 1b. Further, two O-ring grooves 1d and 1e are formed on the outer peripheral surface of the inner tube 1, and an O-ring can be installed in each of the O-ring grooves 1d and 1e. Further, a water guide chamber 1f is formed inside the inner pipe 1 and coaxially communicates with the water passageway R of the water discharge pipe T, and an opening 1g communicating with the outside is formed in this water guide chamber 1f.

The heat insulating cap 2 is made of a resin material having heat insulating properties, and can be fitted onto the outer periphery of the inner tube 1 from the left side in the figure.
After the rings are attached to the respective O-ring grooves 1d and 1e, the heat insulating cap 2 can be fitted into the inner pipe 1, and the left end of the heat insulating cap 2 has a shape that can be fitted into the convex portion 1b of the inner pipe 1. A fitting hole 2a is formed, and when the fitting hole 2a is fitted into the convex portion 1b, the heat insulating cap 2 can cover the outer peripheral surface of the inner tube 1. After that, the ring groove 1 of the convex portion 1b
By fitting the snap spring 3 to c,
The heat insulating cap 2 is prevented from being removed and is firmly integrated with the outer periphery of the inner tube 1. Further, a discharge portion 2b is formed integrally with the heat insulating cap 2 in a hanging shape, and a discharge port 2c is formed in this discharge portion 2b. This discharge port 2c communicates with the water conduit chamber 1f and the opening 1g of the inner pipe 1, and the hot water supplied from the water conduit R passes through the opening 1g from the water conduit chamber 1f, and is discharged to the outside from this discharge port 2c. Ru. A threaded portion 2d is formed on the outer periphery of the discharge portion 2b, and a separate cap member is screwed onto this threaded portion 2d from the outside.
The discharge part 2b can be covered to hide it from the outside. Furthermore, a threaded portion 2e is also formed on the outer circumferential surface of the left end of the heat insulating cap 2 in the figure, and a cover 4 is screwed onto this threaded portion 2e from the left side in the figure to cover the snap ring 3 portion so as to hide it from the outside. The heat insulating cap 2 and cover 4 can be integrated to provide a clean appearance. This cover 4 can also be made of a resin material having heat insulating properties.

Therefore, since the inner pipe 1 is completely covered by the heat insulating cap 2 and the cover 4, the heat insulating cap 2
Alternatively, by grasping the outer periphery of the cover 4 by hand, the water spout T can be easily rotated to a proper position, and hot water, etc. can be discharged from the discharge port 2c at a predetermined position. Moreover, even if the inner pipe 1 becomes hot when hot water is supplied to the flow channel R, the water temperature will not be transmitted to the heat insulating cap 2, so it can be easily removed from the water outlet pipe T without causing burns or the like.
can be rotated. Moreover, by variously changing the designs of the heat insulating cap 2, cover 4, etc., the design of the tip of the water pipe T can be improved, and the tip of the water pipe T can be given novelty and luxury. I can do it.

In addition, since the inner pipe 1, heat insulating cap 2, and cover 4 of this example can be easily attached to the tip of the water discharge pipe T, they can also be easily attached to the tip of a conventional water discharge pipe. .

(Effect of the invention) The discharge port structure of the faucet fitting of the present invention has one end fixed to the distal end of the water discharge pipe T of the faucet fitting, and a convex portion 1b having a ring groove 1c formed on the outer periphery protruding from the other end. A water guide chamber 1f coaxially communicating with the water passage R in the water discharge pipe T is formed inside the water guide chamber 1f.
An inner tube 1 has an opening 1g that opens perpendicularly to the flow direction, and a fitting hole 2a into which the convex portion 1b of the inner tube 1 can fit, and a cover is provided around the outer periphery of the inner tube 1. The heat insulating cap 2 is made of a heat insulating material and has a discharge part 1b protrudingly fixed in the shape and aligned with the opening 1g. A snap ring 3 for preventing removal is screwed into a threaded portion 2e formed on the outer periphery of the fitting hole 2a of the heat insulating cap 2,
By configuring the periphery of the snap ring 3 with a cover 4 that is coaxially attached to the end of the heat insulating cap 2, the inner pipe and the heat insulating cap are attached to the tip of the water discharge pipe, and the heat insulating cap is attached to the end of the water discharge pipe. The insulation of the tip of the spout pipe can be ensured, so the tip of the spout pipe can be easily rotated by holding it in the hand, preventing burns etc. even when hot water is being supplied to the spout pipe. This improves the operability of the distal end of the water pipe.

In addition, the heat insulating cap is firmly fixed by preventing the inner pipe from coming out via the snap ring, making the installation state strong.Also, since the cover is screwed onto the heat insulating cap, the snap ring, etc. to prevent it from coming out can be attached to the heat insulating cap with this cover. Since the cover can be covered with a lid, and the cover is attached coaxially with the heat insulating cap, the external appearance is extremely neat and clean, and the design of the tip of the water pipe can be improved.

Furthermore, by appropriately changing the design of the heat insulating cap and cover, the design can be further improved.
