Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and relates to a faucet valve core, and particularly to a novel faucet valve core structure. Background Technology

[0002] As the core component of a faucet, the faucet valve core directly controls the direction, pressure, and flow of water, and its quality directly affects water quality, lifespan, and user experience. The main materials used include ceramic, stainless steel, ball valves, and roller valves.

[0003] After long-term use, the static sealing interface between the housing and the internal valve core assembly of traditional faucet valve cores is prone to failure due to aging or wear, resulting in leakage. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel sealing faucet valve core structure.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel faucet valve core structure includes an upper shell and a lower shell. The upper shell has a cavity for communicating with the lower shell, and the upper shell and the lower shell are fixedly connected by a snap fastener. The upper shell has a valve nozzle with an opening at the top that communicates with the cavity. A valve seat is provided inside the valve nozzle, and the valve seat is hollow. A rotatable valve stem is installed inside the valve seat. The valve stem has a fixed roller for supporting it, and the fixed roller extends to both ends of the valve stem. Fixing holes for fixing the roller are symmetrically opened on the inner wall of the valve seat. An installation groove is opened on the outer surface of the valve seat. A sealing component for sealing is sleeved in the installation groove, and the other end of the sealing component abuts against the inner wall of the valve nozzle.

[0006] In the above-mentioned novel faucet valve core structure, the sealing component is provided with a sealing ring and a positioning ring from the outside to the inside, and an elastic element with a reset function is provided between the sealing ring and the positioning ring. The upper and lower ends of the mounting groove are provided with circular slots, and the upper and lower ends of the positioning ring have retaining rings that cooperate with the circular slots.

[0007] In the aforementioned novel faucet valve core structure, the sealing component is made of an elastic material.

[0008] In the aforementioned novel faucet valve core structure, the sealing ring, elastic element, and positioning ring are integrally molded.

[0009] Compared with existing technologies, the new faucet valve core structure adopts a composite structure of "sealing ring-elastic element-positioning ring" for the sealing component. When the valve stem rotates and generates bias pressure, the elastic element can effectively store energy and push the sealing ring to automatically reset, always maintaining a tight fit with the inner wall of the valve nozzle, and ensuring stable sealing performance.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the novel faucet valve core structure includes an upper housing 1 and a lower housing 2. The upper housing 1 has a cavity communicating with the lower housing 2, and the upper housing 1 and lower housing 2 are fixedly connected by a snap-fit ​​mechanism. The upper housing 1 and lower housing 2 are detachably fixed via a snap-fit ​​structure 4, facilitating assembly and maintenance. The top of the upper housing 1 has a valve nozzle 3 with an opening communicating with the cavity. A valve seat 4 is located inside the valve nozzle 3, and the valve seat 4 is hollow. A rotatable valve stem 5 is installed inside the valve seat 4. The valve stem 5 is provided with a fixed roller 6 for its support function, and the fixed roller 6 extends to both ends of the valve stem 5. The fixing holes for fixing the fixed roller 6 are symmetrically opened on the inner wall of the valve seat 4. The two ends of the fixed roller 6 extend out of the valve stem 5 and are embedded in the symmetrically arranged fixing holes on the inner wall of the valve seat 4, thereby realizing the stable rotation of the valve stem 5 in the valve seat 4. The valve seat 4 is provided with a mounting groove 7 on the outside. A sealing component 8 for sealing function is sleeved in the mounting groove 7. The other end of the sealing component 8 abuts against the inner wall of the valve nozzle 3.

[0016] To elaborate further, the sealing assembly 8 is provided with a sealing ring 9 and a positioning ring 10 from the outside to the inside. The sealing ring 9 is tightly attached to the inner wall of the valve nozzle 3 to form a reliable seal. An elastic element 11 with a reset function is provided between the sealing ring 9 and the positioning ring 10. When the valve stem 5 rotates, it will squeeze the sealing ring 9 to one side. After the pressure is released, the sealing ring 9 resets and seals through the elastic element 11. Circular slots 12 are provided at both the upper and lower ends of the mounting groove 7. The upper and lower ends of the positioning ring 10 have retaining rings 13 that cooperate with the circular slots 12. The retaining rings 13 at the upper and lower ends of the positioning ring 10 are engaged in the circular slots 12 to achieve axial fixation of the sealing assembly 8.

[0017] To elaborate further, sealing component 8 is made of elastic material.

[0018] To elaborate further, the sealing ring 9, the elastic element 11, and the positioning ring 10 are all integrally molded, which simplifies the structure and enhances the sealing stability.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0020] Although this document frequently uses terms such as upper housing 1, lower housing 2, valve nozzle 3, valve seat 4, valve stem 5, fixing roller 6, mounting groove 7, sealing assembly 8, sealing ring 9, positioning ring 10, elastic element 11, retaining groove 12, and retaining ring 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
