[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] like Figure 1-5 As shown, in the first embodiment, a double valve core body is proposed, and the double valve core body includes a valve core housing 100, a water connection piece 200, a mounting seat 300 and a mounting seat housing 400; The valve core housing 100 is provided with a through hole 110, and the mounting seat 300 is inserted into the mounting seat housing 400, and the two are inserted into the through hole 110 together; the mounting seat 300 is provided with mounting grooves 310 for mounting the valve core at both ends, and a first water port 320 and two second water ports 330 are provided on the side; the water connection member 200 is arranged in the valve core housing 100 and is fixedly connected to the first water port 320; the two second water ports 330 are respectively connected to the mounting grooves 310 at both ends of the mounting seat, and the first water port 320 is simultaneously connected to the mounting grooves 310 at both ends of the mounting seat 300.

[0020] In the present embodiment, the valve core housing 100 and the mounting seat housing 400 are both tubular and can be made of a stainless steel tube or a copper tube, which is easy to manufacture. The first water port 320 and the second water port 330 are not limited to being water outlets or water inlets, and can be connected to the water outlet pipe or the water inlet pipe according to actual needs. For example, a water purifier can make the second water port the water inlet and the first water port the water outlet; a toilet companion can make the first water port the water inlet and the second water port the water outlet. Regarding the position of the first water port 320 and the second water port 330, the angle design position between the first water port 320 and the second water port 330 can be set according to actual needs, which can be as follows Figure 1 and Figure 2 The 180 degree horizontal angle shown can also be 90 degrees. The valve core housing 100 and the mounting seat housing 400 are used as the outer shell of the faucet, and generally adopt metal materials that are not easy to rust, while the water connection piece 200 and the mounting seat 300 are selected from plastics. The overall structure is easy to install, saves materials, and is more economical.

[0021] Preferably, Figure 1-6 As shown, a valve core cover 120 is provided on the valve core housing 100. A threaded portion 210 is provided at one end of the water connection piece 200, and a mounting portion 220 is provided at the other end, and the threaded portion 210 is threadedly connected to the first water passage 320. A clamping piece 230 is provided at one end of the water connection piece 200 close to the threaded portion 210, and a clamping groove 340 is provided on one side of the mounting seat 300 close to the first water passage 320, and the clamping piece 230 is embedded in the clamping groove 340. Clamping interfaces are provided at both ends of the clamping groove 340, and the edge of the clamping piece 230 is embedded in the clamping interface. A positioning ring 240 is provided at one end of the water connection piece 200 close to the mounting portion 220.

[0022] In this preferred embodiment, the mounting portion 220 at the upper end of the water connection member 200 is generally in the shape of a hexagonal nut, which is convenient for rotating the entire water connection member 200 so that the threaded portion 210 is threadedly connected to the first water port 320. However, due to size limitations, the threaded portion 210 is relatively short, has fewer threads, and the depth of connection with the first water port 320 is also relatively shallow; in actual use, the mounting seat 300 is stressed, which easily leads to unstable threaded connection. Therefore, the structure of the clamping piece 230 and the clamping groove 340 is also provided in this preferred embodiment to enhance the lateral force of the mounting seat 300 and prevent the water connection member 200 and the mounting seat 300 from falling off or breaking due to collision. Further, the role of the clamping interface plays the role of installation prompt, prompting the clamping piece 230 to be fully embedded in the clamping groove 340 and enhance the installation effect. When the water connection member 200 is installed in the valve core housing 100, the positioning ring 240 plays a limiting role.

[0023] In the second embodiment, a method for installing the double valve core body of the first embodiment is provided. The method for installing the double valve core body comprises the following steps: The mounting seat housing 400 is sleeved on the outer side of the mounting seat 300, and the mounting groove 310, the first water opening 320 and the second water opening 330 are exposed; Install the water connection piece 200 into the valve core housing 100 so that the water connection piece 200 is located on the upper side of the through hole 110; Insert the mounting seat housing 400 and the mounting seat 300 into the through hole 110 together; The mounting portion 220 on the top of the water connection piece 200 is screwed to fix the threaded portion 210 on the bottom of the water connection piece 200 with the first water passage 320 . At this time, the snap-fit ​​piece 230 on the water connection piece 200 is embedded in the snap-fit ​​groove 340 on the mounting seat 300 .

[0024] In this embodiment, since the existing "cross"-shaped double valve core bodies are all made of metal materials, in order to reduce costs, it is necessary to use pipe fittings to process the outer shell of the double valve core body, and then use plastic to make the inner core. In other words, a reasonable arrangement of the installation method of the double valve core body can reflect the degree of cost savings. The mounting seat shell 400 and the mounting seat 300 of this embodiment can be pre-installed, and when both are inserted into the through hole 110, the water connection piece 200 is installed to complete the assembly. The overall installation method is simple, economical and practical.

[0025] In a third embodiment, a faucet with a double valve core body is provided, wherein the faucet with a double valve core body comprises the double valve core body, a water pipe 500, a threaded pipe 600, a valve core and a switch 700 described in the first embodiment; A third water port 250 is provided at one end of the water connection piece 200 away from the threaded portion 210; the water pipe 500 is connected to the third water port 250 and the second water port 330 respectively, the threaded pipe 600 is threadedly connected to the bottom of the valve core housing 100, the valve core is installed at both ends of the mounting seat 300, and the switch 700 is arranged on the valve core.

[0026] The installation method and working principle of the faucet with double valve core body in this embodiment are as follows: The installation method of the double valve core body is as described in the second embodiment, which will not be repeated here. After installing the double valve core body, take a water pipe 500 and connect it to the third water port 250, then take two water pipes 500 and insert them into the threaded tube 600, connect them to the second water port 330, and then screw the threaded tube 600 into the bottom of the valve core housing 100; install the valve core and switch 700 at the left and right ends of the mounting seat 300 in turn. The final installation diagram is as shown in the figure. Figure 7 shown.

[0027] The faucet of this embodiment has two water flow modes, depending on whether the first water flow port 320 or the second water flow port 330 is used as the water inlet. Take the second water flow port 330 as the water inlet as an example: when working, water flows into the mounting seat 300 from the two second water flow ports 330, respectively enters the valve cores at both ends of the mounting seat 300, and flows out from the first water flow port 320 after being divided by the valve core.

[0028] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
