Description

Technical Field

[0001] This utility model belongs to the field of bathroom technology, and relates to a faucet, and more particularly to a multi-seal faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water. It has the effect of saving water. Traditional faucets lack a sealing mechanism between the valve stem and the valve seat, which can easily lead to water leakage on the valve stem after long-term use, affecting the safety of the product. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a multi-sealing faucet.

[0004] The objective of this utility model can be achieved through the following technical solution: A multi-seal faucet, characterized in that it includes a faucet body, the top of which has an opening, a valve seat with a central through hole is disposed within the opening, a valve stem is disposed within the through hole of the valve seat, and one end of the valve stem extends to the outside of the valve seat, a nut cap is installed on the top of the valve seat, the nut cap is sleeved on the valve stem, the valve stem has an annular sealing element for sealing, the annular sealing element abuts against the through hole of the valve seat, an annular groove is formed on the top of the annular sealing element on the valve stem, a sealing assembly is installed on the groove, the sealing assembly consists of a circular ring and a sealing ring, the circular ring is engaged in the annular groove.

[0005] In the aforementioned multi-seal faucet, both the circular ring and the sealing ring are made of silicone rubber. The sealing ring has a tapered cross-section and deforms according to the size of the sealing space.

[0006] In the aforementioned multi-seal faucet, the circular ring and the sealing ring are integrally formed to form a sealing assembly, and the sealing assembly is installed in the annular groove of the valve stem by an interference fit.

[0007] In the aforementioned multi-seal faucet, the bottom of the valve stem is provided with a plug rod for blocking the water outlet hole inside the faucet body.

[0008] Compared with existing technologies, this multi-seal faucet adopts a multi-seal structure combining an annular seal and a sealing assembly. The annular seal rests against the through hole of the valve seat, forming the first line of defense and effectively preventing water leakage from the basic gap between the valve stem and the valve seat. The sealing assembly, composed of a circular ring and a sealing ring, is located on top of the annular seal, further enhancing the sealing effect and forming a double sealing guarantee, greatly reducing the possibility of leakage. Attached Figure Description

[0009] Figure 1 This is a 3D diagram of a multi-seal faucet.

[0010] Figure 2 This is a cross-sectional view of this multi-seal faucet.

[0011] Figure 3 This is a partial cross-sectional view of this multi-seal faucet.

[0012] In the diagram, 1. Faucet body; 2. Valve seat; 3. Valve stem; 4. Nut cap; 5. Annular seal; 6. Annular groove; 7. Sealing assembly; 8. Circular ring; 9. Sealing ring; 10. Plug rod. Detailed Implementation

[0013] 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.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, this multi-seal faucet includes a faucet body 1. The top of the faucet body 1 has an opening, and a valve seat 2 with a central through hole is disposed within the opening. A valve stem 3 is disposed within the through hole of the valve seat 2, with one end of the valve stem 3 extending outside the valve seat 2. A nut cap 4 is installed on the top of the valve seat 2, and the nut cap 4 is fitted onto the valve stem 3. The valve stem 3 has an annular sealing element 5 for sealing. The annular sealing element 5 abuts against the through hole of the valve seat 2. When the annular sealing element 5 is compressed, it undergoes elastic deformation, resulting in a tight seal. The sealing component 7 is attached to the inner wall of the through hole of the valve stem 3 and the valve seat 2, forming a reliable first layer of sealing barrier, which effectively prevents water from leaking from the gap between the valve stem 3 and the valve seat 2. An annular groove 6 is provided on the top of the annular seal 5 on the valve stem 3. A sealing component 7 is installed on the groove. The sealing component 7 consists of a ring 8 and a sealing ring 9. The ring 8 is engaged in the annular groove 6. During the installation process, a special installation tool is used to slowly press the sealing component 7 into the annular groove 6 to ensure that the ring 8 and the annular groove 6 fit tightly together.

[0015] To elaborate further, both the circular ring 8 and the sealing ring 9 are made of silicone rubber. The cross surface of the sealing ring 9 is conical. The sealing ring 9 deforms according to the size of the sealing space. When the sealing space is small, the conical surface of the sealing ring 9 is compressed, further enhancing the sealing effect. When the sealing space is large, the sealing ring 9 can fill any possible tiny gaps and maintain a good sealing state.

[0016] To elaborate further, the ring 8 and the sealing ring 9 are integrally formed to form the sealing component 7. The integral forming method can reduce the gap between the ring 8 and the sealing ring 9 and improve the sealing performance of the product. Moreover, the sealing component 7 is installed in the annular groove 6 of the valve stem 3 by interference fit.

[0017] To elaborate further, the bottom of the valve stem 3 is equipped with a plug rod 10 for blocking the water outlet hole inside the faucet body 1.

[0018] 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.

[0019] Although this document frequently uses terms such as faucet body 1, valve seat 2, valve stem 3, nut cap 4, annular seal 5, annular groove 6, sealing assembly 7, circular ring 8, sealing ring 9, and plug rod 10, the possibility of using other terms is not excluded. These terms are used 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.
