Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a horizontal fast electric hot water faucet. Background Technology

[0002] A faucet is a switch device used to control water flow. It is typically installed on water pipes, sinks, bathtubs, and other water supply and drainage equipment. It is operated manually or automatically to turn water on and off and regulate the flow rate. Its core function is to conveniently control water usage. However, existing faucets have several defects. Firstly, there are structural reliability issues. Current electric water faucets use welded flange structures for their housings. The welding process inevitably produces metallurgical defects such as porosity, slag inclusions, and incomplete fusion. Residual stress exists in the weld joint area. Under high temperature and pressure cyclic conditions, the probability of fatigue crack initiation due to stress concentration increases significantly. Furthermore, the welding process... The sealing performance at the interface is affected by welding deformation. Under the vibration load generated by water flow, the seal is prone to failure, leading to the risk of water leakage and electric leakage, which seriously affects the safety and service life of the product. Secondly, the production efficiency is low. The traditional welding flange shell production process is lengthy, involving eight to ten processes such as pipe cutting, flange welding, post-weld flaw detection, and pressure testing. In the whole machine assembly stage, the dimensional deviation of the welding flange leads to poor assembly adaptability, requiring manual calibration and adjustment. The assembly time per unit is long, and the assembly defect rate caused by welding deformation is high, making it difficult to achieve automated large-scale production, which seriously restricts the improvement of production efficiency and cost control.

[0010] As a further technical solution of this utility model, a limit post is provided inside the valve cover, and a stop tooth is provided on the inner wall of the limit post. A shaft is provided inside the limit post and is sleeved in the through hole. The stop tooth is engaged with the drive tooth. A handle is provided on the valve cover.

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. Through the optimization of structural mechanics and the elimination of welded flanges through a straight-body integrated structure design, the device avoids stress concentration and metallurgical defects introduced by traditional welding processes. The device designs the heating tube as a straight-body structure, avoiding the quality risks brought about by welding processes and reducing the probability of failures such as water leakage and electrical leakage caused by welding defects. During water flow and thermal expansion and contraction, the stress distribution is more uniform in the straight-body structure, effectively reducing material fatigue damage caused by stress concentration, and enabling the heating tube to withstand long-term high temperature, high pressure, and high flow rate repeated cycles. In complex working environments, the structural stability is significantly enhanced, thereby greatly extending the product's service life, reducing after-sales maintenance costs, and improving the product's market competitiveness. The straight-body shell simplifies the production process, reducing complex procedures such as welding and flaw detection. It can be manufactured using integrated molding technology, significantly shortening the production cycle and reducing production energy consumption. In the overall assembly process, the elimination of welding flanges makes the assembly of the shell and other components simpler. There is no need to consider the complex operations such as positioning and fixing of welding flanges, which can achieve quick plug-in or threaded connection, reducing assembly difficulty and operational error rate, improving the automation level of the production line, and greatly improving the overall assembly efficiency.
