Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a faucet valve core that facilitates the determination of the opening range. Background Technology

[0002] The faucet valve core is a highly integrated, replaceable core functional module installed within the faucet valve body. Essentially, it's a multi-way directional valve. Through user operation, it alters the opening and closing of the internal flow channels and their cross-sectional area, thereby achieving core functions such as opening and closing the fluid (water), flow regulation, and temperature control (for mixing valves). It consists of a valve core housing, valve disc, valve stem, and several matching seals. Rotating the valve stem causes the valve disc to rotate, allowing water to pass through the valve core housing or be blocked by the valve disc and valve core housing, thus controlling the faucet's water output or cutting off the water flow.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When the existing faucet valve core is installed inside the faucet, it is difficult to judge the opening range. It can only be visually observed by the water flow rate. If the water flow and water pressure are unstable during use, it is easy to cause the opening angle to be too large or too small. After the water flow and water pressure are restored, it is easy to cause the flow rate to be too large or too small. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a faucet valve core that facilitates the determination of the opening angle, provides stable water flow control, and makes it easy to judge the opening range.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a faucet valve core for easy judgment of opening range, comprising an outer shell with a water outlet on the side wall and an integrally formed rotating core inserted into the outer shell from the top. The bottom of the outer shell is also fitted with a water inlet base whose top surface is fastened to the rotating core. The inner wall of the outer shell is integrally formed with a stop tooth. The rotating core includes a rotating core body inserted into the outer shell from the top. The bottom side wall of the rotating core body is embedded with a stop structure that can cooperate with the stop tooth.

[0006] A further improvement is that the water inlet base includes a water inlet pipe that is inserted into the outer shell from the bottom and an opening and closing component that is fitted to the bottom and movably engaged with the upper surface of the water inlet pipe. The rotating core also includes a connecting plate with a fastening protrusion integrally formed on the bottom of the rotating core. The upper surface of the opening and closing component is integrally formed with a fastening groove that can cooperate with the fastening protrusion on the connecting plate.

[0007] A further improvement is that the gear shift structure includes a shrinkage groove integrally formed on the bottom side wall of the rotating core and a protruding block whose outer wall is attached to and slidably connected to the inner wall of the shrinkage groove, and a spring is also provided between the end of the protruding block and the end of the inner wall of the shrinkage groove.

[0008] A further improvement is that a number of sealing ring grooves are integrally formed on the outer wall of the rotating core, and a number of sealing rings are installed in the sealing ring grooves.

[0009] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0010] In the process of using this invention, when the rotating core is twisted to control the opening and closing of the device, the protruding block of the gear position structure will also engage with the gear position teeth inside the outer shell. Under the action of the spring, after the rotating core and the device rotate a certain angle, the protruding block will be pushed into the recess of the gear position teeth by the elastic force of the spring. This causes the recess of the gear position teeth and the protruding block to collide and produce a sound. At this time, the rotation angle of the rotating core and the device can be accurately judged by judging the number of sounds, preventing the opening and closing angle from being too large or too small, and making the water flow control more precise.

[0011] In this invention, when connecting the opening / closing component and the rotating core, a connecting disc is directly integrally formed on the rotating core. The connecting disc is integrally formed with a snap-fit ​​protrusion, which cooperates with the snap-fit ​​groove on the opening / closing component to complete the quick installation. There is no need to use pins to connect the three components, which reduces the number of parts during installation and makes the installation simpler and more convenient.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1-4As shown, the technical solution adopted in this specific embodiment is: a faucet valve core that facilitates the judgment of the opening range, including an outer shell 1 with a water outlet 13 on the side wall and an integrally formed rotating core 2 inserted into the outer shell 1 from the top. A water inlet base is also installed at the bottom of the outer shell 1, with its top surface fastened to the rotating core 2. The water inlet base includes a water inlet pipe 32 inserted into the outer shell 1 from the bottom and an opening / closing member 31 that is fitted to and movably engaged with the upper surface of the water inlet pipe 32. The rotating core 2 also includes a connecting plate 21 with a fastening protrusion integrally formed at the bottom of the rotating core 23. The upper surface of the opening / closing member 31 is integrally formed with a fastening groove 33 that can cooperate with the fastening protrusion on the connecting plate 21. The inner wall of the outer shell 1 is integrally formed with... The valve core 2 includes a gear tooth 14 and a rotating core 23, which is inserted into the outer shell 1 from the top. A gearing structure 22, which engages with the gear tooth 14, is embedded in the bottom side wall of the rotating core 23. The gearing structure 22 includes a contraction groove 221 integrally formed on the bottom side wall of the rotating core 23 and a protruding block 223 whose outer wall is fitted and slidably connected to the inner wall of the contraction groove 221. A spring 222 is also provided between the end of the protruding block 223 and the end of the inner wall of the contraction groove 221. In use, the valve core is first installed by inserting the rotating core 2 and the integrally formed connecting disc 21 from the top of the outer shell 1, aligning the gearing structure 22 with the gear tooth 14 on the inner wall of the outer shell 1, and then inserting the valve core 23 from the bottom of the outer shell 1. Insert the water inlet base so that the edge of the water inlet pipe 32 of the water inlet base fits against the inner wall of the outer casing 1, and the snap-fit ​​groove 33 formed on the upper surface of the opening and closing element 31 at its top engages with the snap-fit ​​protrusion on the connecting plate 21. Both the opening and closing element 31 and the water inlet pipe 32 are existing technologies and are widely used in the field of valve cores, so they will not be described in detail here. At this time, the rotating core 2 can be turned to make the opening and closing element 31 rotate synchronously, thereby controlling the opening or closing of the water inlet pipe 32. Then, the faucet valve core is installed into the faucet. When in use, the opening and closing element 31 is rotated by turning the rotating core 2, thereby controlling the opening and closing of the water circuit. When the rotating core 2 is turned to control the opening and closing element 31 to open, the gear position structure 22 will also be activated. The protruding block 223 fits into the gear tooth 14 inside the outer shell 1. Under the action of the spring 222, after the rotating core 23 of the rotating core 2 and the opening and closing part 31 rotate a certain angle, the protruding block 223 can be pushed into the recess of the gear tooth 14 under the elastic force of the spring 222. This causes the recess of the gear tooth 14 to collide with the protruding block 223 and produce a sound. At the same time, the protruding end of the protruding block 223 can be an arc-shaped structure, which reduces the resistance when twisting. At this time, the rotation angle of the rotating core 23 of the rotating core 2 and the opening and closing part 31 can be accurately judged by judging the number of sounds, preventing the opening and closing part 31 from being too large or too small, and making the water flow control more precise.

[0021] The outer wall of the rotating core 2 has several sealing ring grooves integrally formed, and several sealing rings are installed in the sealing ring grooves, which helps to improve the sealing between the rotating core 2 and the outer shell 1 and prevent water leakage.

[0022] The working principle of this utility model is as follows: First, install the faucet valve core. Insert the rotating core 2 and the integrally formed connecting plate 21 from the top of the outer shell 1, aligning the stop structure 22 with the stop teeth 14 on the inner wall of the outer shell 1. Then, install the water inlet base from the bottom of the outer shell 1, ensuring the edge of the water inlet pipe 32 of the water inlet base fits against the inner wall of the outer shell 1. The locking groove 33 formed on the upper surface of the opening / closing element 31 at its top engages with the locking protrusion on the connecting plate 21. Both the opening / closing element 31 and the water inlet pipe 32 are existing technologies widely used in the valve core field and will not be described in detail here. Then, twist the rotating core 2 to make the opening / closing element 31 rotate synchronously, thereby controlling the opening or closing of the water inlet pipe 32. Finally, install the faucet valve core into the faucet. During use, [the valve core is inserted]. The opening and closing of the water passage is controlled by rotating the core 2. When the core 2 is rotated to open the opening and closing of ...
