According to information from the National Intellectual Property Administration, Chaozhou Kenei Sanitary Ware Technology Co., Ltd. obtained a patent named "A Side Inlet Valve" in 2024 (Authorization Announcement Number: CN 221811009 U). This side inlet valve features a compact structure. Its inlet body is equipped with an inlet pipe and an outlet pipe at the top, and it has a built-in control valve with a pressure relief hole. The water storage cup is connected to the lower end of the inlet body to form a containment cavity. It works in conjunction with a lift rod and a float bucket to precisely control the water flow. This design is compact in size and is particularly suitable for smart toilets with limited installation space, providing a new solution for the design optimization of smart bathroom products.

Meanwhile, on June 24, 2025, Arrows Home Furnishing was granted an invention patent for "A Water Level Adjustment Mechanism for Inlet Valves" (Patent Application No. CN202111495040.4). This mechanism, through a unique combination of components such as a float bucket, float shell, and adjustment screw, achieves a wide range of water level adjustments and has the advantages of small size and excellent working stability. Since the beginning of this year, Arrows Home Furnishing has obtained 291 patent authorizations, demonstrating its continuous investment and innovative strength in technological research and development. In 2024, the company's R&D investment reached 372 million yuan, an increase of 8.84% year-on-year. Please provide the text you want to be translated.
HUIDA Sanitary Ware also obtained the utility model patent authorization for "A Flow-limiting Component of an Inlet Valve and the Inlet Valve" on July 9, 2024 (Patent Application No. CN202323127101.9). Its flow-limiting component, through the plug-in connection of the check valve and the flow limiter, can stabilize the water flow rate under high water pressure, reduce deformation, and provide technical support for the stable operation of the inlet valve under complex water pressure conditions.

From a market perspective, as consumers' demands for the quality and performance of bathroom products increase, the technological innovation of the water inlet valve, a key component, has driven product upgrades. For instance, the J108/J13011 series of water inlet valves independently developed by Vibo Sanitary Ware are made of food-grade polymer materials and high-precision copper core components. They have undergone 12 precise tests and can operate stably under extreme water pressure ranging from 0.05 to 0.8 MPa, effectively solving the problems of leakage, high noise, and slow response of traditional water inlet valves. Among them, the J13011 series, through fluid mechanics design, has reduced the inlet noise to 25 decibels, is compatible with 99% of mainstream toilet models, and has a post-sale problem rate of less than 0.https://www.maoyt.com/index.php?r=product/edit&pid=43267279
