Description

Technical Field

[0001] The utility model relates to the field of sanitary products, and particularly relates to a faucet. Background Art

[0002] When producing a washbasin faucet (countertop faucet), generally, the sand casting process is adopted to form structures such as the main body and the water outlet arm. At the same time, in the later stage, the valve core installation position needs to be machined by boring the inner end face, and various water channels need to be machined on the main body by drilling holes, and butt threads are machined at the water channel openings; if you want to reduce the material loss, generally, the bottom of the main body will be made as concave as possible to save materials. Since the water inlet holes and the water outlet holes of the cold and hot water valve cores are first offset from the center of the valve core, the water inlet holes at the bottom of the main body also follow the offset when drilling holes, which leads to the offset of the water inlet pipeline when connecting, and it is easy to interfere with the inner wall of the threaded installation cylinder at the bottom of the main body. Therefore, some manufacturers will directly lead the butt thread to the bottom end face of the main body by welding a copper pipe during production, so as to ensure normal water connection; therefore, the overall process is complex, the material loss is large, the production cost is high, and it is overly dependent on external processing of other industries.

[0003] In response to the above problems, the applicant applied on May 18, 2023, and obtained authorization on October 20, 2023. A washbasin faucet with the patent number CN202321239338.3 includes a through cylinder, and water outlet holes are provided on the outer wall of the cylinder; it also includes a water distribution plate, the water distribution plate is provided with a first water inlet channel, a second water inlet channel and a water outlet channel, and one end of the water outlet channel on the side of the water distribution plate corresponds to the water outlet hole and is welded and butted with the water outlet hole. The lower surface of the water distribution plate is provided with a first water inlet pipe and a second water inlet pipe, one end of which is welded to the first water inlet channel and the second water inlet channel, and the other end extends downward to the lower end of the cylinder. Docking heads are provided at the lower ends of the first water inlet pipe and the second water inlet pipe; a gland for fixing the cold and hot water valve core on the water distribution plate is provided at the upper end of the cylinder; a water outlet arm corresponding to and communicating with the water outlet hole is provided on the side of the cylinder, and the water outlet arm is provided with a water outlet nozzle.

[0004] Although this utility model adopts a water distribution plate structure to reduce the industry support field, reduce the production process, reduce the dependence on large-scale production equipment during production, thereby reducing the production cost, and at the same time ensuring the advantages of beautiful appearance, but in subsequent production, the applicant found that the water distribution plate structure can be further optimized, so as to further enhance its product competitiveness on the original basis. Summary of the Utility Model

[0005] Based on the above problems, the purpose of the present utility model is to provide a faucet that can effectively reduce the industry support field, reduce the production process, reduce the dependence on large-scale production equipment during production, thereby reducing the production cost, reducing the weight and improving the assembly speed at the same time.

[0007] In the above structure, the cylinder and the outlet branch arm are formed by cutting and blanking metal thin tubes. The support plate supplies water to the valve core installation cavity by blanking a thin plate and welding the water inlet pipe. After the outlet pipe is welded to the support plate, it needs to be docked with the through hole to realize the water outlet of the outlet branch arm. However, due to the accuracy alignment problem during the welding and bending of the outlet pipe, the pipe orifice of the outlet pipe cannot be guaranteed to be perfectly aligned with the through hole. Therefore, a docking cone sleeve is provided. After the support plate is welded and fixed in the cylinder, the docking cone sleeve is inserted into the through hole. The outer conical surface and the inner conical surface of the docking cone sleeve are used to guide the through hole and the outlet pipe to a concentric state. Then, the outer wall of the docking cone sleeve is directly welded to the orifice of the through hole, and at the same time, the outlet pipe is welded to the inner wall of the docking cone sleeve. Then, the outlet branch arm is welded to the outer wall of the cylinder to complete the assembly of the water circuit, effectively reducing the overall weight of the product while simplifying the production process and greatly saving the production cost.

[0010] The present utility model is further configured such that the support plate is provided with circumferential positioning pits / holes formed by stretching or blanking.

[0011] In the above structure, the circumferential positioning pits / holes are used to match with the positioning posts of the valve core to determine the circumferential direction of the valve core.

[0052] In this embodiment, the valve core gland 16 is formed by stamping and stretching a metal plate and is provided with a thread 161.
