[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] This utility model provides the following technical solution:

[0026] As attached Figure 1-5As shown, a sink faucet with a multi-seal structure includes a faucet body 1 mounted on a wall. The faucet body 1 includes a water outlet pipe 2, a faucet switch structure 3, and a fixing structure 4. The faucet switch structure 3 includes a normally open switch 31, a connecting pipe 32, and a push-button switch 33. The connecting pipe 32 is connected to both the normally open switch 31 and the push-button switch 33. The push-button switch 33 is connected to one end of the water outlet pipe 2, and the other end of the water outlet pipe 2 has a water outlet 5. The faucet body 1 is characterized by further including a first sealing structure 6 and a second sealing structure. 7. The first sealing structure 6 and the second sealing structure 7 are arranged in annular sealing structures. The first sealing structure 6 is disposed between the connecting pipe 32 and the push switch 33, and the second sealing structure 7 is disposed between the push switch 33 and the water outlet pipe 2. The first sealing structure 6 includes a first sealing groove 61 and a first sealing ring 62. The first sealing groove 61 is formed at the connection between the connecting pipe 32 and the push switch 33, and the cross-sectional shape of the first sealing groove 61 is triangular. The first sealing ring 62 is disposed within the first sealing groove 61 and is sealed to the first sealing groove 61. In this embodiment, by setting the first sealing structure 6 and the second sealing structure 7, the sealing performance of the sink faucet is effectively improved, water leakage is prevented, and the safety and reliability of use are enhanced. Specifically, the first sealing structure 6 is disposed between the connecting pipe 32 and the push switch 33, and its triangular cross-sectional shape, the first sealing groove 61, fits tightly with the first sealing ring 62, forming a stable sealing effect. When the push switch 33 is pressed, water flows through the faucet switch to the push switch 33. The push switch 33 and the connecting pipe 32 are subjected to a certain water pressure impact. The first sealing ring 62 can also remain stable in the first sealing groove 61, and is not easy to fall off or deform, thereby ensuring the sealing between the connecting pipe 32 and the push switch 33.

[0027] The push-button switch 33 extends into the inner wall of the connecting pipe 32, pressing against the first sealing ring 62 within the first sealing groove 61. The first sealing ring 62 has an inner sealing part 621, an outer sealing part 622, and a sealing connection part 623. The inner sealing part 621 extends into the first sealing groove 61 and seals against the inner wall of the connecting pipe 32 and the push-button switch 33. A connecting groove 624 is formed between the inner sealing part 621, the outer sealing part 622, and the sealing connection part 623. The top end of the connecting pipe 32 extends into the connecting groove 624 and seals against the first sealing ring 62. In this embodiment, the first sealing groove 61 is formed by combining the connecting pipe 32 and the push-button switch 33. This design not only simplifies the installation process of the sealing structure but also improves the fitting accuracy between the sealing groove and the sealing ring. This combination method enhances the structural strength between the connecting pipe 32 and the push-button switch 33, improving the stability and durability of the overall structure. During long-term use, even under continuous water flow, the first sealing ring 62 remains stable within the first sealing groove 61, preventing loosening or leakage, thus ensuring the sealing performance of the sink faucet. The inner sealing part 621, outer sealing part 622, and sealing connection part 623 of the first sealing ring 62 reinforce the seal between the connecting pipe 32 and the push-button switch 33 from different angles. The inner sealing part 621 extends into the first sealing groove 61 and makes close contact with the inner wall of the connecting pipe 32 and the push-button switch 33, forming the first sealing barrier and effectively preventing water leakage from the inside. The outer sealing part 622 is located on the outside of the first sealing groove 61 and connects with the outer walls of the connecting pipe 32 and the push-button switch 33, providing additional sealing protection and fixation. The sealing connection part 623 connects the inner sealing part 621 and the outer sealing part 622, ensuring the stability and sealing performance of the entire first sealing ring 62. This design not only improves the sealing effect but also enhances the stability and durability of the structure, enabling the sink faucet to maintain good sealing performance during use, preventing water leakage, and improving the safety and reliability of use.

[0028] The first sealing groove 61 has an inclined groove wall, and the inner sealing part 621 has a triangular cross-section. The inner sealing part 621 has a pipe sealing surface 625 corresponding to the inclined groove wall of the first sealing groove 61. In this embodiment, by setting the inclined groove wall and the triangular cross-section of the inner sealing part 621, the fit between the first sealing ring 62 and the first sealing groove 61 is made tighter. When the push switch 33 is pressed, the pipe sealing surface 625 of the inner sealing part 621 fits tightly against the inclined groove wall of the first sealing groove 61, effectively preventing water leakage from the gap. This design not only improves the sealing performance but also enhances the stability and durability of the structure. At the same time, the triangular cross-section of the inner sealing part 621 can better disperse pressure when subjected to water pressure impact, reduce the deformation and wear of the sealing ring, maintain the stability of the sealing ring, and thus extend the service life of the sink faucet.

[0029] The second sealing structure 7 includes a second sealing ring 71 and a second sealing groove 72. The second sealing ring 71 is disposed between the push-button switch 33 and the water outlet pipe 2. The second sealing ring 71 includes a sealing part 711, a connecting part 712, and a limiting part 713. The sealing part 711 extends into the side wall of the water outlet pipe 2 and the inner wall of the push-button switch 33 near the water outlet 5 for sealing connection. The connecting part 712 is disposed between the sealing part 711 and the limiting part 713. The limiting part 713 is disposed on the outside of the water outlet pipe 2 and the push-button switch 33. In this embodiment, the setting of the second sealing ring 71 further enhances the sealing performance between the push-button switch 33 and the water outlet pipe 2. As the part that directly contacts the water flow, the sealing part 711 is made of soft and wear-resistant material, which can effectively prevent water from leaking from tiny gaps. At the same time, the shape of the sealing part 711 matches the shape of the side wall of the water outlet pipe 2 and the inner wall of the push-button switch 33, ensuring the tightness of the seal. The connecting part 712 connects the sealing part 711 and the limiting part 713, making the overall structure of the second sealing ring 71 more stable and less prone to deformation. The limiting part 713 is located on the outside of the water outlet pipe 2 and the push switch 33, limiting the second sealing ring 71 to prevent displacement under water pressure, thus ensuring the durability of the sealing effect. This design not only improves the sealing performance of the sink faucet but also enhances its structural stability and durability, providing users with a safer and more reliable user experience.

[0030] The second sealing groove 72 is disposed between the push-button switch 33 and the water outlet pipe 2. The second sealing groove 72 has a sealing groove portion 721 and a limiting groove portion 722. The sealing groove portion 721 is positioned corresponding to the sealing portion 711, and the limiting groove portion 722 is positioned corresponding to the limiting portion 713. The sealing groove portion 721 allows the sealing portion 711 to be tightly embedded within it, forming an effective seal. The shape and size of the sealing groove portion 721 match the sealing portion 711, ensuring the tightness and reliability of the seal. Simultaneously, the limiting groove portion 722 limits the second sealing ring 71, preventing displacement under water pressure and further enhancing the durability of the seal. This design not only improves the sealing performance of the sink faucet but also ensures its stability and durability during long-term use, providing users with a superior user experience.

[0031] The fixing structure 4 includes a fixing base 41, a connecting rod 42, and a wall-mounted fixing plate 43. The fixing base 41 is fixedly mounted on the upper side of the water outlet pipe 2. The connecting rod 42 has connecting holes 421 at both ends, which are respectively connected to the fixing base 41 and the wall-mounted fixing plate 43. In this embodiment, the connecting rod 42 connects the fixing base 41 and the wall-mounted fixing plate 43, achieving a stable installation through the connecting holes 421. The fixing base 41 not only enhances the connection strength between the water outlet pipe 2 and the fixing structure 4 but also provides additional support, making the entire faucet body 11 more stable and less prone to shaking. This fixing structure 4 design not only improves the stability and durability of the sink faucet but also provides users with a more convenient and safer installation experience.

[0032] A rotating groove 422 is provided on the side of the connecting rod 42 near the fixed base 41. The rotating groove 422 is perpendicular to the central axis of the connecting hole 421. The fixed base 41 protrudes from the water outlet pipe 2, and the fixed base 41 and the rotating groove 422 are positioned correspondingly. The fixed base 41 is disposed within the rotating groove 422, and the connecting rod 42 can adjust the connection angle of the fixed base 41 through the rotating groove 422. In this embodiment, the rotating groove 422 allows the connecting rod 42 to be adjusted according to the length of the faucet extension and specific circumstances. Users can flexibly adjust the connection angle between the connecting rod 42 and the fixed base 41 through the rotating groove 422 according to the installation position of the sink faucet and their usage habits, so that the faucet body 11 can be more stably installed on the wall, and it also facilitates fine-tuning of the angle as needed during use. This design not only improves the flexibility and adaptability of the sink faucet, but also provides users with a more comfortable and convenient user experience. In addition, the cooperation between the rotating groove 422 and the fixed base 41 also enhances the stability of the connection structure.

[0033] The faucet switch structure 3 includes several normally open switches 31, all of which are connected to the connecting pipe 32.
