[0022] The top of the valve core sleeve 34 is integrally formed by stamping and has an outwardly expanding boss 33, which helps to obtain a larger volume on the top surface of the valve core sleeve 34, thereby accommodating the switch valve core. At the same time, the bottom of the valve core sleeve 34 is smaller, which makes it easier for the valve chip 12 to be inserted into the faucet body 1 for installation.
[0023] The top of the switch valve core 31 is also fitted with a twist handle 5, which makes it easier to open and close the switch valve core 31 with less effort, makes the operation more convenient, and improves the user experience.
[0024] The working principle of this embodiment is as follows: When using this utility model, firstly, the pipe is cut to form the faucet body 1, and the outer wall of the end of the faucet body 1 is threaded to form a connecting thread 13. Then, another pipe is cut to form a valve core sleeve 34, and a hole is punched in the faucet body 1 at the position where the valve core sleeve 34 is installed, allowing the valve core sleeve 34 to be inserted into the faucet body 1 through the hole. Then, a connecting plate 2 and a valve chip 12 are formed by stamping. A small-diameter pipe is taken and bent to form a bent water pipe 11. The valve core sleeve 34 is inserted into the hole in the faucet body 1, and its outer surface is welded to the faucet body 1. The end of the bent water pipe 11 is welded to the valve chip 12 to form a bent water inlet structure, and the bent water inlet structure is inserted into the faucet body 1, aligning the valve chip 12 with the bottom surface of the valve core sleeve 34. Finally, the two are welded and fixed together. Then, the switch valve core 31 is installed inside the valve core sleeve 34. The switch valve core 31 is existing technology and a standard valve core can be used. Finally, the connecting plate 2 is installed at the other end of the bent water pipe 11, and the opening on the inner wall of the connecting plate 2 is welded to the end of the bent water pipe 11. Then, the connecting plate 2 is welded to the water inlet end of the faucet body 1. At this time, the installation of the faucet is completed, and water is introduced from the bent water pipe 11. At the same time, the faucet can be threaded to the external pipe through the connecting thread 13 on the outer wall of the faucet body 1. The water flows out from the drain port 32 on the valve core sleeve 34 by rotating the switch valve core 31. When the water circuit is closed, the water flow can be cut off by rotating the switch valve core 31. The faucet does not need to use sand core casting during processing, avoiding the generation of waste sand cores that pollute the environment. The processing technology is simple, more controllable, and has a high yield. Example 2:
[0025] See Figures 1-2 , Figure 4As shown, the difference between this specific embodiment and Embodiment 1 is that the bent water inlet structure includes a bent water pipe 11 with one end welded to the inner wall of the connecting plate 2, and a valve chip 12 welded and fixed to the other end of the bent water pipe 11 and integrally stamped with the bottom end of the valve core sleeve 34. The bent water pipe 11 is formed by bending a pipe fitting. By integrally stamping the valve chip 12 with the valve core sleeve 34, the welding steps and the stamping steps of the valve chip 12 are saved, reducing the complexity of the process, and at the same time improving the sealing performance between the valve core sleeve 34 and the valve chip 12.
[0026] The working principle of this embodiment is as follows: When using this utility model, firstly, the pipe is cut to form the faucet body 1, and the outer wall of the end of the faucet body 1 is threaded to form a connecting thread 13. Then, another pipe is cut to form a valve core sleeve 34, and a hole is punched in the faucet body 1 at the position where the valve core sleeve 34 is installed, allowing the valve core sleeve 34 to be inserted into the faucet body 1. Next, a connecting plate 2 is formed by stamping, and the valve core sleeve 34 is stamped to form the bottom valve chip 12. A small-diameter pipe is taken and bent to form a bent water pipe 11. The valve core sleeve 34 is inserted into the hole in the faucet body 1, and its outer surface is welded to the faucet body 1. The bent water pipe 11 is then inserted into the faucet body 1, and its end is welded to the valve chip 12 to form a bent water inlet structure. Finally, the valve core sleeve 34 is installed inside the valve core sleeve 34. The switch valve core 31 is existing technology and can use a standard valve core. Finally, a connecting plate 2 is installed at the other end of the bent water pipe 11, and the opening on the inner wall of the connecting plate 2 is welded to the end of the bent water pipe 11. Then, the connecting plate 2 is welded to the inlet end of the faucet body 1, completing the faucet installation. Water is introduced through the bent water pipe 11, and the faucet is threaded to the external pipe via the connecting thread 13 on the outer wall of the faucet body 1. Water flows out from the drain port 32 on the valve core sleeve 34 by rotating the switch valve core 31. When the water circuit is closed, rotating the switch valve core 31 disconnects the water flow. The faucet does not require sand core casting during processing, avoiding waste sand core pollution. The processing technology is simple, more controllable, and has a high yield.
