Description

Technical Field

[0001] The present application belongs to the technical field of faucets, and more specifically, relates to a faucet and a sealing member suitable for the faucet. Background Art

[0002] A traditional faucet is usually composed of multiple components. Its structure generally includes a body, a valve core, a mounting base and a handle switch. The body has a space inside, the valve core and the mounting base are assembled and fixed in the space, and the handle switch is set on the valve core in a way that can control the water flow state.

[0003] The valve core and the mounting seat need to be precisely assembled to prevent water leakage. In order to ensure that the faucet can achieve a good sealing effect, a large number of sealing rings are installed between the valve core and the mounting seat to prevent gaps from forming between the valve core and the mounting seat.

[0004] However, while conventional faucets can achieve a sealing effect by installing a large number of sealing rings, this also makes the structure between the valve core and the mounting base more complex to accommodate these sealing rings, thereby increasing manufacturing costs. Furthermore, after long-term use of the faucet, these sealing rings will age, deform, or wear out, making replacement of the sealing rings difficult. Utility Model Content

[0005] In view of this, an object of the present invention is to provide a faucet that not only reduces the number of seals used but also makes maintenance of the faucet more convenient.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a faucet comprising a base, a water valve and a switch, the base having a accommodating space and a water outlet, the water valve being arranged in the accommodating space and having a water channel structure, the water channel structure being connected to the water outlet, the switch being connected to the water valve and being used to control the opening or closing of the water channel structure; wherein the water valve comprises an inner sleeve, an outer sleeve, a valve core, a water pipe and a sealing member, wherein the inner sleeve has an annular convex wall arranged along the outer circumference, the portion of the inner sleeve below the annular convex wall is located in the outer sleeve and is in contact with the inner sleeve of the outer sleeve. A confluence space is formed between the walls, the valve core is arranged in the inner sleeve and a portion is connected to the switch; wherein, the inner sleeve has an upper clamping groove, the outer sleeve has a lower clamping groove, one end of the water pipe is located between the upper clamping groove and the lower clamping groove, and the water pipe is connected to the confluence space; wherein, the sealing component includes a first sealing ring and a second sealing ring, the first sealing ring is sleeved on the water pipe, the upper clamping groove and the lower clamping groove clamp the first sealing ring, the second sealing ring is connected to the first sealing ring, and the second sealing ring is clamped between one side of the annular protrusion of the inner sleeve and the top edge of the outer sleeve.

[0007] The utility model further provides a sealing member, comprising a first sealing ring and a second sealing ring, wherein the first sealing ring is located on a virtual first plane, the second sealing ring is connected to the first sealing ring and is located on a virtual second plane, and the first plane and the second plane are non-parallel planes.

[0008] The present invention achieves a sealing effect on the faucet by simply clamping the second sealing ring of the seal between the annular ridge of the inner sleeve and the top edge of the outer sleeve, and directly fitting the first sealing ring of the seal onto the water pipe. Thus, the inner sleeve only needs the annular ridge, eliminating the need for a complex design on the outer sleeve. This, combined with the provision of a single sealing ring, achieves a sealing effect, thereby reducing the difficulty and manufacturing cost of the faucet. Furthermore, when the sealing ring needs to be replaced, it can be replaced simply by detaching the inner sleeve, the outer sleeve, and the water pipe, making repair and maintenance of the faucet more convenient.

[0062] In order to more clearly illustrate the present invention, a preferred embodiment is given below with detailed description in conjunction with the drawings. Figures 1 to 10 FIG. 1 shows a faucet 100 according to a preferred embodiment of the present invention. The faucet 100 is connected to two water pipes 1 for directing water into the faucet 100. The faucet 100 includes a base 10, a water valve 20, and a switch 30. The base 10 has a receiving space S and a water outlet 11. The receiving space S is located within the base 10. The water valve 20 is disposed in the receiving space S and has a water path structure connected to the water outlet 11. The switch 30 is connected to the water valve 20 and is used to control whether the water path structure is opened or closed. The water valve 20 includes an inner sleeve 21, an outer sleeve 22, a valve core 23, a water pipe 24, and a sealing member 25.

[0063] like Figures 4 and 5 As shown, the inner sleeve 21 has an annular protrusion 211 disposed along its outer circumference. The outer wall of the inner sleeve 21 has a recessed groove 212 formed by recessing the portion below the annular protrusion 211. The inner sleeve 21 has a plurality of water inlet pipes 213 and a water outlet pipe 214. The water inlet pipes 213 are spaced apart, and a seal (not shown) may be added to the outer periphery of each water inlet pipe 213 to enhance leak prevention.

[0064] like Figure 4 and Figure 5 As shown, the portion of the inner sleeve 21 below the annular protrusion 211 is located in the outer sleeve 22 and forms a confluence space T ( Figure 10 As shown), the groove 212 is connected to the confluence space T. The outer sleeve 22 has a protrusion 221, which is formed by protruding from the outer bottom wall of the outer sleeve 22. The protrusion 221 has a plurality of mounting holes 222 for externally connecting the water pipes 1. Each of the mounting holes 222 corresponds to and is connected to each of the water inlet pipes 213. In this embodiment, the outer sleeve 22 has a plurality of fixing blocks 223 on the outer periphery near the bottom; the base 10 has a plurality of stop blocks 12 in the accommodating space S and at positions corresponding to the fixing blocks 223. Each of the fixing blocks 223 abuts against each of the stop blocks 12 ( Figure 10As shown, this ensures that the outer sleeve 22 and the base 10 are accurately positioned during installation and prevents relative movement between the outer sleeve 22 and the base 10, thereby enhancing the stability of the overall structure. In other embodiments, the outer sleeve 22 may also be provided with a fixing block 223, and the base 10 may be provided with a corresponding stop block 12 to similarly prevent the outer sleeve 22 from rotating relative to the base 10.

[0065] like Figure 6 As shown, the valve core 23 includes a valve housing 231 and a valve stem 232. The valve housing 231 is fixedly coupled to the inner sleeve 21 so as to be non-rotatable relative to the inner sleeve 21. The valve stem 232 axially passes through the valve housing 231, and a portion of the valve stem 232 is connected to the switch 30. More specifically, the valve housing 231 of the valve core 23 has an aligning portion comprising two protrusions 2311 disposed on the outer bottom wall of the valve core 23. The inner sleeve 21 has an aligned portion comprising two recessed holes 215 disposed on the inner bottom wall of the inner sleeve 21 and located on either side of the water outlet pipe 214. Each recessed hole 215 is positioned corresponding to a position of a protrusion 2311. When the valve core 23 is coupled to the inner sleeve 21, each protrusion 2311 is inserted into a corresponding recessed hole 215. By disposing the protrusions 2311 and the recessed holes 215 , the valve core 23 and the inner sleeve 21 can be accurately positioned and the valve core 23 will not rotate relative to the inner sleeve 21 , thereby improving the accuracy and stability of the overall installation.

[0066] In other embodiments, the aligning portion may be provided with a protruding column 2311, and the aligned portion may be provided with a corresponding recessed hole 215, thereby similarly achieving a non-rotatable engagement between the valve core 23 and the inner sleeve 21. Furthermore, the aligning portion and the aligned portion may also be provided with other types of mating arrangements, such as the aligning portion being provided with two recessed holes and the aligned portion being provided with the two protruding columns.

[0067] like Figure 6 As shown, the valve core 23 has a plurality of water inlet holes 2312 and a water outlet hole 2313. Each water inlet hole 2312 corresponds to and is connected to each water inlet pipe 213. The water outlet hole 2313 is arranged corresponding to the position of the water outlet pipe 214. The water outlet hole 2313 is connected to the water outlet pipe 214 and the confluence space T, and the two protrusions 2311 are located on both sides of the water outlet hole 2313.

[0068] Please cooperate Figure 10As shown, the water channel structure includes a water inlet channel and a water outlet channel, wherein the water inlet channel includes the mounting holes 222 provided on the outer sleeve 22, the water inlet pipes 213 provided on the inner sleeve 21, and the water inlet holes 2312 provided on the valve housing 231 of the valve core 23, so that water can flow from each mounting hole 222 through each water inlet pipe 213 into each water inlet hole 2312. The water outlet channel includes the water outlet holes 2313 provided on the valve housing 231 of the valve core 23, and the water outlet pipe 214 provided on the inner sleeve 21. The water outlet pipe 214 is connected to the confluence space T, so that water can flow from the water outlet holes 2313 through the water outlet pipe 214 into the confluence space T formed between the outer sleeve 22 and the inner sleeve 21. In this embodiment, the number of the mounting holes 222 of the outer sleeve 22, the water inlet pipes 213 of the inner sleeve 21 of the second water pipe 1, and the water inlet holes 2312 of the valve core 23 are respectively illustrated as two. In other embodiments, it is not ruled out that the number of the mounting holes 222 of the outer sleeve 22, the water inlet pipes 213 of the inner sleeve 21 of the water pipe 1, and the water inlet holes 2312 of the valve core 23 are correspondingly set to one or more than two.

[0069] Please continue to cooperate Figure 7 and Figure 10 As shown, the connection between the water pipe 24 and the inner sleeve 21 and the outer sleeve 22 is achieved through an upper clamping groove 216 on the inner sleeve 21, which communicates with the groove 212. The outer sleeve 22 has a lower clamping groove 224 corresponding to the upper clamping groove 216. One end of the water pipe 24 is located between the upper clamping groove 216 and the lower clamping groove 224, connecting the confluence space T with the groove 212. In this embodiment, a protrusion 241 is provided at one end of the water pipe 24. The inner sleeve 21 has an engaging groove 217, and the protrusion 241 engages with the engaging groove 217, thereby preventing the water pipe 24 from rotating relative to the inner sleeve 21 and the outer sleeve 22.

[0070] Please continue to cooperate Figures 8 to 10As shown, the sealing member 25 includes a first sealing ring 251 and a second sealing ring 252, wherein the first sealing ring 251 is located on a virtual first plane P1, and the second sealing ring 252 is connected to the first sealing ring 251 and located on a virtual second plane P2, wherein the first plane P1 and the second plane P2 are non-parallel planes. In this embodiment, the first plane P1 and the second plane P2 are perpendicular to each other, and the area enclosed by the first sealing ring 251 is smaller than the area enclosed by the second sealing ring 252. More specifically, the water pipe 24 has an annular groove 242 adjacent to the protrusion 241. The first sealing ring 251 is sleeved on the annular groove 242 of the water pipe 24, and the upper clamping groove 216 and the lower clamping groove 224 clamp the first sealing ring 251. The second sealing ring 252 is clamped between one side of the annular protrusion 211 of the inner sleeve 21 and the top edge of the outer sleeve 22. In this embodiment, the top edge of the outer sleeve 22 has an annular groove 225. The second sealing ring 252 is located in the annular groove 225 and is clamped by the annular protrusion 211. Through the configuration of the sealing member 25, the water valve 20 can achieve a sealing effect.

[0071] In summary, the faucet 100 achieves a sealing effect simply by clamping the second sealing ring 252 of the sealing member 25 between the annular ridge 211 of the inner sleeve 21 and the top edge of the outer sleeve 22, and by directly fitting the first sealing ring 251 of the sealing member 25 over the water pipe 24. Thus, the inner sleeve 21 only needs to be provided with the annular ridge 211, the outer sleeve 22 with the corresponding annular groove 225, and the sealing member 25 to achieve a sealing effect. This eliminates the need for a complex design on the outer sleeve 22, thereby reducing the difficulty and cost of manufacturing the faucet 100. Furthermore, when the sealing member 25 needs to be replaced, it can be replaced by simply detaching the inner sleeve 21, the outer sleeve 22, and the water pipe 24, making repair and maintenance of the faucet 100 more convenient.

[0072] In this embodiment, the groove 212 is provided on the inner sleeve 21 . In other embodiments, the groove 212 may also be provided on the outer sleeve 22 and communicate with the confluence space T, or the groove 212 may be provided on both the outer sleeve 22 and the inner sleeve 21 , which can also increase the amount of water flowing into the water pipe 24 .

[0073] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
