[0026] Embodiment

[0027] Combined with Figures 1 to 8 As shown, this embodiment provides a welding faucet, including a faucet body. An installation cavity and a water outlet branch arm 2 having a water flow channel are provided on the faucet body. The faucet body is composed of at least two housings assembled and welded together, and the housings are formed by high-vacuum die casting; a limiting post and a limiting groove are respectively provided on two mutually assembled housings.

[0028] The faucet body is composed of at least two housings assembled and welded together, and the housings are formed by high-vacuum die casting; a faucet body with a complex inner cavity is divided into multiple housings to make it better formed. At the same time, the inner cavity of the housing can be better processed, so that the inner cavity can meet the pipe-passing requirements after being assembled and welded into the faucet body, reducing the processing amount of the inner cavity and the processing cost; and the use of high-vacuum die casting greatly reduces the surface roughness of the housing after forming, avoiding the formation of air bubbles causing pits on the polished housing surface, and products with clear ridges on the appearance can be produced, improving the yield rate of the appearance after polishing.

[0029] Specifically, in this embodiment, as Figure 4As shown, the faucet body is assembled and welded by two half - split shells. The faucet body includes a cylindrical main body 1 and a water outlet branch arm 2 connected to the side of the main body 1; this half - split is along the axis of the main body 1 and the center line of the water outlet branch arm 2, dividing the faucet body into a symmetric first shell 3 and second shell 4. At least two limiting posts are arranged in the first shell 3, and limiting grooves adapted to the limiting posts are arranged in the second shell 4 to perform positioning and assembly to ensure the accuracy of assembly, and further ensure the accuracy of subsequent welding.

[0030] In this embodiment, a valve core cavity for installing a valve core is provided in the faucet body. A water outlet channel communicating with the valve core cavity is arranged in the water outlet branch arm 2. A limiting platform 5 is arranged at the bottom of the valve core cavity, and a plurality of through holes facilitating the connection of the water inlet pipeline with the valve core are arranged on the limiting platform 5; a first internal thread 6 is arranged at the upper installation opening at the top of the main body 1 for connecting a gland to fix the valve core placed in the valve core cavity. A fixing boss is arranged in the inner cavity at the bottom of the main body 1, and a second internal thread 7 is arranged on the fixing boss for fixing the body on the washbasin countertop. And an inner annular step 8 is formed inward at the bottom of the main body 1, and a sealing groove 9 for installing a sealing ring is arranged at the bottom end face of the inner annular step 8. A third internal thread is arranged on the water outlet branch arm 2 for installing a water outlet part. Of course, in other embodiments, it can also be that an outer annular step is formed outward at the bottom of the main body 1, a sealing groove 9 for installing a sealing ring is arranged at the bottom end face of the outer annular step, and the second internal thread 7 can be directly arranged on the inner cavity wall at the bottom of the main body 1.

[0031] Preferably, as Figure 8 shown, after installing the water - passing component 14 in one of the shells and then assembling and welding it with other shells. The accuracy and convenience of installing the internal water - passing component 14 are realized. Further, the material of the water - passing component is at least one of copper alloy, plastic, stainless steel, and ceramic.

[0032] In another embodiment, the faucet body can also be assembled and welded by two shells split from top to bottom. As Figure 5 shown, a cover plate 10 is cut out from the upper part of the faucet body so that the water outlet flow channel in the water outlet branch arm 2 of the lower shell 11 has an upper opening, which is convenient for subsequent processing and the installation of water - passing parts.

[0033] In yet another embodiment, the faucet body can also be assembled and welded by two shells split from left to right. As Figure 6 and Figure 7As shown, it is divided along the axis of the main body 1 of the faucet body to form a left main body 1 part and a right main body 1 part with the water outlet branch arm 2, so as to facilitate the subsequent processing of the installation cavity and the installation of the water passing parts. Of course, as shown in the figure, the left and right division method can also be carried out along a certain radial position of the water outlet branch arm 2, which will not be elaborated in detail here.

[0034] It should be noted that no matter how the faucet body is divided, it is for the convenience of molding and processing the inner cavity wall of the divided shell, further ensuring the appearance quality after assembly welding and facilitating the installation of the internal water passing parts.
