[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, this embodiment provides a water tap, including a water inlet body 10. The water inlet body 10 has a water inlet channel 11 and a water outlet channel 12 formed inside it. The water inlet channel 11 includes a horizontal extension portion 115 and a vertical extension portion 116, both of which are straight channels and are connected. The water inlet body 10 is equipped with a control valve 13, which is located between the water inlet channel 11 and the water outlet channel 12 and is used to control the opening and closing of the water inlet channel 11 and the water outlet channel 12.

[0018] Furthermore, the water inlet body 10 is integrally injection molded.

[0019] Preferably, there are two water inlet channels 11 and one water outlet channel 12. The two water inlet channels 11 are independent of each other. One water inlet channel 11 is used to introduce hot water and the other water inlet channel 11 is used to introduce cold water. The control valve 13 is a mixing valve 131. The mixing valve 131 can mix cold water and hot water and is used to adjust the ratio of cold and hot water mixing. It can also control the opening and closing of the water inlet channel 11 and the water outlet channel 12.

[0020] Furthermore, one end of the horizontal extension portion 115 of the two water inlet channels 11 is provided with a first opening 113 on the side wall of the water inlet body, and the other end is connected to the vertical extension portion 116. The lower end of the vertical extension portion 116 is provided with a second opening 114 on the bottom surface of the water inlet body. The first opening 113 and the second opening 114 are process openings left for the horizontal extension portion 115 and the vertical extension portion 116 of the mold.

[0021] Specifically, the horizontal extensions 115 of the two water inlet channels 11 extend towards each other from the left and right ends of the water inlet body 10, and are staggered in the middle of the water inlet body 10. The vertical extensions 116 of the two water inlet channels 11 are respectively connected to the ends of the two horizontal extensions 116 located in the middle of the water inlet body 10, and the two vertical extensions 116 are adjacent to each other. Specifically, the ends of the two horizontal extensions 115 that are far apart from each other are respectively provided with the first openings 113 at the left and right ends of the water inlet body 10, and the two vertical extensions 116 are provided with the second openings 114 in the middle of the bottom of the water inlet body 10.

[0022] Specifically, the upper ends of the two vertically extending portions each have an outlet 111 on either the left or right side of the water inlet body 10. The inlet end 121 of the water outlet channel 12 is located between the two outlets 111. The mixing valve 131 has two inlets and one mixing outlet. The mixing valve 131 is installed on the water inlet body 10 from the side where the two outlets 111 are located. The two inlets of the mixing valve 131 are respectively connected to the two outlets 111, so that cold water and hot water flow through the outlets 111 and the inlets respectively and then mix in the mixing valve 131. The mixing outlet is connected to the inlet end 121 of the water outlet channel 12, so that the mixed water flows through the mixing outlet and then enters the water outlet channel 12.

[0023] Specifically, the mixing valve 131 is provided at the upper end of the vertical extension 116, which enables hot and cold water to quickly and directly enter the mixing chamber of the mixing valve 131 for thorough mixing, thus optimizing the mixing effect and response speed.

[0024] This invention has a compact structure and effectively shortens the flow path of hot and cold water from the inlet to the mixing point, thereby reducing water flow resistance and energy consumption.

[0025] Furthermore, it also includes a base 20, which is integrally injection molded on the bottom side of the water inlet body 10 based on the water inlet body 10. The base 20 also has a fixing part 21 and a blocking part 22. The fixing part 21 is used to connect the base 20 and the water inlet body 10, and the blocking part 22 is used to block the first opening 113 and the second opening 114. The base 20 is provided with a water inlet interface 23 for connecting to the external water channel. The water inlet interface 23 is connected to the water inlet channel 11 of the water inlet body 10. In this utility model, both the water inlet body 10 and the base 20 are integrally injection molded, and the water inlet channel 11 is composed of straight channels. Combined with the integrated blocking part and the integrally molded fixing part 21, the internal structure of the entire faucet is extremely compact and has strong integrity. This design not only saves space, but also significantly improves the structural strength and durability of the faucet.

[0026] Furthermore, the water inlet 23 has threads on its outer periphery, and a nut 25 is screwed onto the water inlet 23.

[0027] Furthermore, a control handle 14 is installed on the control valve 13, and an outlet pipe 15 is connected to the water inlet body 10. The outlet pipe 15 is connected to the water outlet channel 12, and the water flows out from the outlet pipe 15 after passing through the water inlet channel 11, the control valve 13, and the water outlet channel 12.

[0028] Furthermore, it also includes a housing 30, which is fixedly connected to the base 20 and covers the water inlet body 10 to protect the water inlet body 10.

[0029] Specifically, the housing 30 has a channel 31 for inserting a mixing valve 131. The mixing valve 131 can be sealed and installed on the water inlet body 10 by inserting it into the channel 31. The mixing valve 131 can be locked and pressed against the water inlet body 10 by screwing a locking member into the channel 31.

[0030] Furthermore, a snap-fit ​​protrusion 24 is provided on the base 20, and a snap-fit ​​groove is provided on the inner side of the outer casing 30. By snapping the snap-fit ​​protrusion 24 into the snap-fit ​​groove, the outer casing 30 is fixed to the base 20, and can be quickly and tool-free fixed to the base 20, completely covering the internal components.

[0031] Preferably, the fixing part 21 is a hook structure, which is formed on the outer periphery of the surface of the water inlet body 10 where the first opening 113 is located, and the fixing part 21 is hooked on the water inlet body 10 so that the water inlet body 10 and the base 20 are connected together. In this utility model, the fixing part 21 is formed on the base 20, and a firm connection is formed with the water inlet body 10 during injection molding. No additional parts are needed to fix the two, so that the connection between the water inlet body 10 and the base 20 is quick, stable and irreversible, simplifying the assembly process and enhancing the rigidity and stability of the overall structure.

[0032] Preferably, the plugging part 22 includes a first protrusion 221 formed on the hook structure and used to plug the first opening 113, and a second protrusion 222 injection molded on the side of the base 20 facing the bottom surface of the water inlet body 10 and used to plug the second opening 114. In the injection molding process, the first protrusion 221 and the second protrusion 222 seal the first opening 113 and the second opening 114, avoiding the need for subsequent steps to install seals or plugs separately, reducing the number of parts and assembly steps, sealing the process opening, and avoiding the potential leakage risk caused by the failure of additional seals or plugs or improper installation, thus greatly improving the sealing reliability and long-term waterproof performance of the product.

[0033] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
