Technical Field

[0001] The utility model relates to the technical field of faucet accessories, in particular to a faucet. Background Art

[0002] A faucet generally includes a three-way body, a valve core, a valve core seat, a handle, an inlet pipe and an outlet pipe. The three ends of the three-way body are respectively connected to the bottom end of the outlet pipe, the top end of the inlet pipe and the handle. The valve core is connected to the handle to control the opening and closing of the outlet pipe and the inlet pipe to achieve the function of opening and closing the faucet.

[0003] The valve core seat is normally made by precision casting or machining, and then the valve core seat is fixed in the tee body. However, most tee bodies are cast in one piece, so the valve core seat needs to be inserted from one end of the tee body and fixed in the tee body. This connection method is troublesome to assemble and wastes time.

[0004] In view of this, the applicant conducted an in-depth study on the above-mentioned issues, which led to the present case. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-Figure 3 As shown, this embodiment provides a faucet, including a three-way body 10, a valve core seat 20, a valve core (not shown in the figure), a locking nut (not shown in the figure) and a handle (not shown in the figure), wherein the valve core is an existing standardized valve core, the handle is an existing handle, and the locking nut is an existing locking nut, all of which can be purchased directly from the market.

[0024] The three-way body 10 includes a main pipe part 21 and a handle connecting part 22 fixedly connected to the main pipe part 21. The specific fixed connection method between the two can be a conventional method, such as welding or threaded connection. In this embodiment, the fixed connection method is explained by taking welding as an example. The main pipe part 21 and the handle connecting part 22 are arranged perpendicular to each other. The main pipe part is cylindrical. The main pipe part 21 has an inner cavity (not shown in the figure) and a first mounting hole 23, a second mounting hole 24 and a valve core hole 25 respectively connected to the inner cavity. For the convenience of description, in this embodiment, the upper part after the faucet is installed on the countertop is the upper part of each component, and the lower part after the faucet is installed on the countertop is the lower part of each component. Specifically, the main pipe part 21 is arranged vertically, and the first mounting hole 23 is located at At the upper end of the main pipe part 21, the second mounting hole 24 is located at the lower end of the main pipe part 21, and the first mounting hole 23 and the second mounting hole 24 are coaxially arranged, the valve core hole 25 is located on the side wall of the main pipe part 21, the valve core hole 25 is horizontally arranged, and the valve core hole 25 is located between the first mounting hole 23 and the second mounting hole 24, and a first through hole 26 corresponding to the position of the valve core hole 25 is opened in the handle connecting part 22, the valve core seat 20 is in a round cake shape, the valve core seat 20 is installed in the valve core hole 25, the valve core is installed on the valve core seat 20, the handle is connected to the valve core, the installation method of the valve core and the valve core seat and the specific structure of the handle and the valve core are not the content to be protected by the utility model, and this installation method and specific structure are both prior art and will not be described in detail here.

[0025] The projection of the valve core hole 25 on its radial cross section is waist-shaped, and the waist shape includes a first arc edge, a second arc edge and two straight edges connected between the first arc edge and the second arc edge, the centers of the first arc edge and the second arc edge coincide, and the valve core seat 20 abuts against the mouth 25 of the valve core hole at a position corresponding to the straight edge. When the valve core seat 20 abuts against the mouth 25 of the valve core hole and the main pipe part 21 is placed horizontally, the horizontal height of the side of the valve core seat 25 away from the inner cavity of the main pipe part 21 is lower than the horizontal height of the outer peripheral surface of the main pipe part 21 at a position corresponding to the straight edge.

[0026] One end of the handle connecting portion 22 connected to the main pipe portion 21 has a contact portion that matches the outer peripheral surface of the main pipe portion, so as to cover the valve core hole 25 and make the three-way body 10 more beautiful.

[0027] The valve core seat 20 is provided with a plurality of second through holes 28 cooperating with the valve core. In the present embodiment, the number of the second through holes 28 is 3, namely, a water inlet hole, a hot water hole and a water outlet hole. It should be noted that, since the valve core is a standardized part, the positions of the water inlet hole, the hot water hole and the water outlet hole are usually fixed and will not be described in detail here.

[0028] An internal thread 29 is provided on the inner side wall of the end of the handle connecting part 22 away from the main pipe part 21, and an external thread is provided on the outer peripheral surface of the locking nut. The handle connecting part 22 and the locking nut are threadably connected by the internal thread 29 and the external thread. The locking nut is locked and fixed in the handle connecting part 22 by the cooperation of the internal thread 29 and the external thread, thereby limiting and fixing the valve core.

[0029] The tee body 10 is a stainless steel tee body, so that the tee body 10 has the advantages of corrosion resistance and a long service life.

[0030] During installation, the valve core seat 20 is placed in the valve core hole 25. Since the valve core seat 20 is pressed against the mouth of the valve core hole and the position corresponding to the straight edge, the movement of the valve core seat 20 along the axial direction of the valve core hole 25 is limited. Then the handle connecting part 22 and the main pipe part 21 are welded together, and then the valve core is passed through the first through hole from the end of the handle connecting part 22 away from the main pipe part 21 and installed on the valve core seat 20. The valve core is then fixed and installed by a locking nut and a spiral connection. By opening a valve core hole 25 in the main pipe part 21, which is waist-shaped in projection on the radial section, the valve core seat 20 can be directly inserted into the valve core hole 25, limiting the installation position of the valve core seat 25 in the valve core hole, thereby meeting the requirement that the valve core seat is fixed in the main pipe part, and the assembly is easier.

[0031] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, all of which belong to the protection scope of the present invention.
