Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of faucet valve core, specifically relates to a valve core with water flow compensation function. BACKGROUND

[0002] In the field of modern bathroom facilities, as a key component, the performance of the faucet valve core plays a decisive role in user experience. The traditional mixed water valve core is mostly driven by a valve rod to rotate a ceramic moving piece, which changes the overlapping area of the ceramic static piece and the moving piece through-flow hole to adjust the cold and hot water inflow, and realizes water temperature control.

[0003] As shown in the Chinese utility model patent "ceramic control valve for controlling cold and hot water mixing ratio and water outlet quantity and fixed disc" with patent number ZL200420118665.4 (publication number CN2761932Y). However, with the improvement of living quality, such traditional valve cores have exposed many problems in actual use.

[0004] First, the temperature adjustment accuracy cannot meet the demand: the human body is extremely sensitive to water temperature, and the comfortable water temperature range is narrow, usually between 37℃ and 42℃. Within this temperature range, people feel most comfortable when they wash and bathe. However, the existing temperature adjustment valve core generally has the problem of excessive sensitivity in temperature adjustment. In actual operation, people turn the valve rod, but lack of precise angle control mechanism, it is difficult to accurately grasp the rotation amplitude. A little rotation can greatly change the cold and hot water inflow, causing the mixed water temperature to fluctuate sharply. For example, when bathing, if you want to adjust the water temperature, you may turn the valve rod slightly, but the water temperature may suddenly rise, making it difficult for you to bear; when washing hands, the water temperature is originally low, and a slight adjustment may suddenly make the water temperature too high, not only causing discomfort, but also wasting water resources. Such sudden changes in water temperature occur frequently, making it difficult for users to quickly and accurately adjust the water temperature to the desired state, seriously affecting the water use experience, and embarrassing water use scenarios often occur.

[0005] Second, the water outlet mode is single and the function is limited, which cannot adapt to multiple scenes: the moving valve piece of the traditional valve core can only meet the basic functions of manual adjustment of water temperature and flow, and cannot adapt to complex and diverse use scenarios. If the moving valve piece can slide to multiple positions and realize multiple water outlet modes, it can bring more possibilities. For example, when the moving valve piece slides to a specific position, the valve core can switch to a manual adjustment mode, and the user can freely adjust the water temperature and flow size as usual; when the moving valve piece slides to another position, the valve core can open the delay closing function, and after the user finishes using it, the faucet can automatically close according to the preset time without manual operation. Through the design of multiple position sliding, the valve core can have multiple functions such as manual adjustment and delay closing at the same time, greatly improving the applicability of the faucet in different scenes and meeting people's demand for convenient, sanitary and efficient water use.

[0006] Therefore, how to develop a valve core which can realize the switching of multiple water outlet modes by changing the sliding position of the moving valve plate to meet different water use scenarios, and also has a water flow compensation function to extend the temperature adjustment area and make the water temperature adjustment easier to control, is a problem that the person skilled in the art needs to solve.

The upper shell (31) is also provided with a positioning slot (31b), and the base (32) is provided with a positioning block (32b) that can be adapted to the positioning slot (31b).

9. The valve core with water flow compensation function according to claim 6, characterized in that: A limiting device (7) is provided between the valve housing (3) and the rotor (5) to restrict the rotor (5) to rotate only within a set angle. The limiting device (7) includes a first limiting wall (7a) and a second limiting wall (7b) disposed inside the valve housing (3) and spaced apart along the circumference, a third limiting wall (7c) formed on the side of the rotor (5) and adapted to the first limiting wall (7a), and a fourth limiting wall (7d) adapted to the second limiting wall (7b). When the rotor (5) rotates counterclockwise to the set position, the first limiting wall (7a) can abut against the third limiting wall (7c) to restrict the rotor (5) from continuing to rotate. When the rotor (5) rotates clockwise to the set position, the second limiting wall (7b) can abut against the fourth limiting wall (7d) to restrict the rotor (5) from continuing to rotate.
