Description

Technical Field

[0001] The present invention relates to the technical field of faucets, and particularly to a pipe-piercing faucet. Background Art

[0002] In order to reduce product costs, the faucet body needs to be made of zinc alloy parts. Currently, the zinc alloy body usually adopts a two-piece or zinc alloy recasting form. The two-piece faucet will have an obvious demarcation line in appearance, affecting the appearance of the product. Adopting zinc alloy recasting can ensure the integrity of the product appearance.

[0003] The patent with the publication number CN208381425U discloses a faucet, including a faucet body and a water outlet structure. The faucet body has a cavity. The water outlet structure includes an inner pipe and a bubbler. The inner pipe is embedded inside the cavity of the faucet body, and the bubbler is threadedly connected to the water outlet nozzle of the cavity. One end of the water outlet of the inner pipe is detachably fixedly connected to the outer shell of the faucet body, so that the position of the inner pipe of the faucet relative to the water outlet nozzle of the faucet body is fixed. Therefore, the operation of disassembling and cleaning the bubbler will not cause the inner pipe to loosen, avoiding the problem of water leakage of the faucet caused thereby. Specifically, the inner pipe is detachably connected to the outer shell of the faucet body through a first threaded connector. Through the threaded connection relationship formed by the first threaded connector, the first through hole and the threaded hole, a detachable fixed connection relationship is formed between one end of the water outlet of the inner pipe and the outer shell of the faucet body. In addition, the faucet further includes a valve body assembly. The valve body assembly includes a valve body base. The valve body base is provided with a water outlet hole. The water outlet hole is connected to the water inlet of the inner pipe. One end of the water inlet of the inner pipe is provided with a second threaded connector. The second threaded connector is provided with an external thread, and the inner wall of the water outlet hole of the valve body base is provided with an internal thread that cooperates with the second threaded connector. Through the above structural design, the position of the inner pipe relative to the faucet body is fixed. The operation of disassembling and cleaning the bubbler will not cause the inner pipe to loosen, avoiding the problem of water leakage of the faucet caused thereby.

[0004] The disadvantages of the above patent solution are as follows: (1) Through the threaded connection relationship formed by the first threaded connector, the first through hole and the threaded hole, a detachable fixed connection relationship is formed between one end of the water outlet of the inner pipe and the outer shell of the faucet body. This connection relationship has a relatively cumbersome structure. (2) One end of the water inlet of the inner pipe and the water outlet hole of the valve body base are threadedly connected. Since both the inner pipe and the valve body base are installed in the faucet body, and the threaded connection points of these two components are located in the cavity near the inside of the faucet body, they cannot be installed after the faucet body is assembled. Therefore, the faucet body can only be designed as a two-piece split structure. After installing the internal components, the two bodies are fixed together. Therefore, its finished appearance has an obvious demarcation line, affecting the beauty of the product and having an insecure structure. Summary of the Invention

[0005] In order to solve the problems that the existing two-piece split-structure faucet has an obvious dividing line in appearance, which affects the appearance of the product and the structure is not firm, the present invention proposes a faucet with an integrated body, which is specifically as follows.

[0006] A pipe-through faucet includes a valve core, multiple sections of rigid water-conducting members, and an integrated body.

[0007] The body has an inner cavity; the inner cavity has three outer ports, namely a drainage outer port, a water inlet outer port, and a mounting port.

The first dovetail groove structure and the second dovetail groove structure are mutually engaged and fixed, so that the water outlet of the valve core and the water inlet of the adapter are seamlessly connected.

[0013] As a further improvement of the pipe-through faucet of the present invention, the outer periphery of the valve core is a valve core seat, and the first dovetail groove structure is opened on the outer side surface of the valve core seat; the first dovetail groove structure includes two straight grooves parallel to the axis of the valve core, and these two straight grooves gradually incline and approach towards the axis direction; the valve core water outlet is arranged between the two straight grooves; a sealing ring is also ring-embedded on the periphery of the valve core water outlet, and the sealing ring can seamlessly abut against the adapter.

[0014] As a further improvement of the pipe-passing faucet of the present invention, sealing rings are embedded around the outer sides of both ends of the connecting pipe. The two ends of the connecting pipe are respectively inserted into the adapter and the water outlet joint, and are seamlessly connected through the sealing rings respectively.

[0015] As a further improvement of the pipe-passing faucet of the present invention, the water outlet joint includes a pipe fitting and a disc cover. The pipe fitting is obliquely connected to the disc cover and integrally formed, and has a through water flow channel. This water flow channel penetrates from the pipe fitting to the middle of the bottom surface of the disc cover to form a water outlet. The upper surface of the disc cover and a section of the pipe fitting above it are integrally fitted and abutted against the inner top surface of the drainage outer port to be fixed.

[0016] As a further improvement of the pipe-passing faucet of the present invention, the pipe-passing faucet further includes a hollow connecting joint; the connecting joint is installed in the drainage outer port and is seamlessly communicated with the water outlet at the bottom surface of the disc cover.

Specific embodiments

[0034] Some embodiments of the pipe-piercing faucet of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] As Figure 1As shown, it is a schematic cross-sectional view of a pipe-piercing faucet according to the present invention. The pipe-piercing faucet includes a valve core 1, multiple sections of rigid water-conducting members 2, and an integral body 3.

[0036] As Figure 2 shown, the body 3 has an inner cavity which has three outer ports, namely a drainage outer port 31, a water inlet outer port 32, and a mounting port 33.

[0037] Each section of the multiple sections of rigid water-conducting members 2 and the valve core 1 can be sequentially installed into the inner cavity through the mounting port 33.

[0038] Each section of the multiple sections of rigid water-conducting members 2 is seamlessly connected in sequence in the inner cavity, and the outermost end of the multiple sections of rigid water-conducting members 2 is fixed at the drainage outer port 31, and the innermost end is seamlessly connected to the water outlet of the valve core 1. The water inlet of the valve core 1 faces the water inlet outer port 32, and water can flow through it until it reaches the drainage outer port 31.

[0039] For this pipe-piercing faucet, its integral body 3 has no dividing line like a two-piece body. The body 3 is a whole, which is beautiful and firm. Among them, the current two-piece body disassembles the outer shell body into upper and lower two pieces. After installing the internal pipe fittings and the valve core in one piece, then covering the other piece of the body and assembling them together, there is an obvious dividing line after assembly, which is not firm enough.

[0040] For the pipe-piercing faucet of the present invention, the internal use of rigid water-conducting members is not easy to deform and has a long service life. The internal rigid water-conducting members are divided into multiple sections of rigid water-conducting members 2, which reduces the size of the water-conducting components, so that each section of the water-conducting member can be sequentially installed into the inner cavity of the body 3 through the mounting port 33 of the body 3, and each section of the rigid water-conducting member is seamlessly connected in sequence in the inner cavity. The outermost end of the multiple sections of rigid water-conducting members 2 is fixed at the drainage outer port 31 of the body 3, and the innermost end is seamlessly connected to the water outlet of the valve core 1, forming a complete internal water path structure, overcoming the application difficulties of the integral body 3, improving the overall firmness of the faucet, and enhancing the product safety.

[0041] Among them, the integral body 3 can be an inverted L shape and is made of zinc alloy.

[0042] Please refer to Figure 1 , in an embodiment, the multiple sections of rigid water-conducting members 2 are a three-section structure including an adapter 21, a connecting pipe 22, and a water outlet joint 23. The adapter 21, the connecting pipe 22, and the water outlet joint 23 are seamlessly connected in sequence in the body 3. One end of the water outlet joint 23 far from the connecting pipe 22 is the outermost end, and one end of the adapter 21 far from the connecting pipe 22 is the innermost end.

[0043] The adapter 21, the connecting pipe 22, and the water outlet joint 23 are all made of rigid materials, such as metal or rigid plastic. In this embodiment, the internal waterway components are divided into three sections: the adapter 21, the connecting pipe 22, and the water outlet joint 23. This can make the sizes of the components in each section smaller, facilitating installation into the main body 3 through the installation opening 33. In some embodiments, the internal pipeline can also be reasonably designed into other numbers of sections according to the size of the installation opening 33, such as a two-section design, a four-section design, and so on.

[0044] As Figure 2 shown, a positioning surface 310 that fits the outermost end of the multi-section rigid water-passing member 2 is provided on the inner top surface of the drainage outer port 31 of the main body 3. The outermost end has a downward water outlet, and the back of the water outlet at the outermost end abuts against the positioning surface 310 to be fixed.

[0045] As Figure 3 shown, it is a structural diagram of the valve seat 11 outside the valve core 1. The lower end of the valve seat 11 is fixed to the main body 3. A valve core water outlet 101 and a first dovetail groove structure 102 are designed on the outer side of the valve seat 11. The first dovetail groove structure 102 is arranged on both sides of the valve core water outlet 101. The first dovetail groove structure 102 includes two straight grooves parallel to the axis of the valve core 1, and these two straight grooves gradually incline and approach towards the axis direction; the valve core water outlet 101 is arranged between the two straight grooves. A sealing ring is also embedded around the valve core water outlet 101, and this sealing ring can seamlessly abut against the adapter 21.

[0046] As Figure 4 shown, it is a schematic structural diagram of the adapter 21 installed in the main body 3. One end of the adapter 21 away from the connecting pipe 22 is provided with a transfer water inlet 211 and a second dovetail groove structure 212. The second dovetail groove structure 212 is arranged on both sides of the transfer water inlet 211.

[0047] As Figure 5 shown, it is a top view of the adapter 21. The second dovetail groove structure 212 includes two parallel plates that incline inwards. The first dovetail groove structure 102 can be mutually embedded and fixed with the second dovetail groove structure 212, so that the valve core water outlet 101 and the transfer water inlet 211 are seamlessly connected. During installation, the first dovetail groove structure 102 of the valve seat 11 is vertically aligned with the second dovetail groove structure 212 of the adapter 21, and then inserted into it, so that the first dovetail groove structure 102 and the second dovetail groove structure 212 are mutually fitted and locked. Thus, the valve core 1 and the adapter 21 are relatively fixed. At this time, the valve core water outlet 101 and the transfer water inlet 211 are mutually butted, and there is a sealing device around the circumference, which can pass water flow and will not seep water.

[0048] As Figure 1As shown, the connecting pipe 22 is a straight pipe section structure, and sealing rings are embedded around the outer sides of both ends thereof. The two ends of the connecting pipe 22 are respectively inserted into the adapter 21 and the water outlet joint 23, and are tightly and seamlessly connected through the sealing rings respectively, thereby seamlessly connecting the water circuit.

[0049] As Figure 6 shown, the water outlet joint 23 includes a pipe fitting 231 and a disc cover 232. The pipe fitting 231 is obliquely connected to the disc cover 232 and integrally formed to form a water flow channel that penetrates internally. This water flow channel penetrates from the pipe fitting 231 to the middle of the bottom surface of the disc cover 232 to form a water outlet. As Figure 1 shown, the upper surface of the disc cover 232 and a section of the pipe fitting 231 above it are integrally fitted and abutted against the positioning surface 310 of the drainage outer port 31 to be fixed.

[0050] As Figure 7 shown, the positioning surface 310 in the main body 3 includes a flat circular mating surface 3101 that fits the upper surface of the disc cover 232, and a concave arc top mating surface 3102 that fits a section of the pipe fitting 231 above the disc cover 232.

[0051] As Figure 1 shown, the pipe-through faucet further includes a hollow connecting joint 4. The connecting joint 4 is installed in the drainage outer port 31 and is seamlessly communicated with the water outlet at the bottom surface of the disc cover 232.

[0052] The drainage outer port 31 of the main body 3 is provided with internal threads, and the outer side of the connecting joint 4 is provided with external threads adapted to the internal threads. A sealing ring is also embedded around the top of the connecting joint 4. The connecting joint 4 is fixed to the drainage outer port 31 by threaded connection and is seamlessly abutted against the peripheral edge of the bottom surface of the disc cover 232 through the sealing ring, so as to abut the water outlet joint 23 against the inner top surface of the drainage outer port 31 for fixation. There is no need to use screws or the like to fix the water outlet joint 23, and the structure is simple and firm, and the installation and disassembly are convenient. Preferably, there is a section of inner shrinkage ring at the upper end of the connecting joint 4, and this inner shrinkage ring is embedded in the disc cover 232 to increase the structural firmness.

[0053] As Figure 1 shown, the pipe-through faucet further includes a hollow bubbler 5. The connecting joint 4 is also provided with internal threads, and the bubbler 5 is provided with external threads. The bubbler 5 is installed in the connecting joint 4 through the cooperation of the internal and external threads. The bubbler 5 has a convex top, and a plurality of water-passing micropores are densely arranged on the convex top, and the plurality of water-passing micropores communicate with the water outlet at the bottom surface of the disc cover 232.

[0054] Please refer to Figures 8 to 12 , one installation method of the pipe-through faucet of the present invention is: (1) AsFigure 8 , first, orient the end of the disc cover 232 of the water outlet connector 23 towards the end of the drainage outer opening 31 of the body, pass the entire water outlet connector 23 through the installation opening 33 of the body 3, and insert it into the horizontal pipe section of the inverted L-shaped body 3. The end of the disc cover 232 is snugly abutted against the positioning surface 310 of the body 3; (2) As Figure 9 , then rotate and install the connection joint 4 from the drainage outer opening 31 of the body 3 and stop when it abuts against the bottom surface of the disc cover 232; (3) As Figure 10 , then insert the connecting pipe 22 from the installation opening 33 of the body 3, insert it into the horizontal pipe section of the inverted L-shaped body 3, and insert it into the end of the water outlet connector 23 to be relatively fixed; (4) As Figure 11 , then insert the adapter 21 from the installation opening 33 of the body 3, insert it into the horizontal pipe section of the inverted L-shaped body 3, and sleeve it on the end of the connecting pipe 22 to be relatively fixed; (5) As Figure 12 , in the final stage, first install the valve core seat 11, including aligning the vertical first dovetail groove structure 102 with the vertical second dovetail groove structure 212. After alignment, insert the valve core seat 11, fix the bottom of the valve core seat 11 on the internal structure of the body 3, and finally install the main body part of the valve core 1; (6) As Figure 1 , at the drainage outer opening 31, rotate and install the bubbler 5 into the connection joint 4 to complete the installation.

[0055] In this embodiment, the body 3 of the pipe-through faucet is made as an integral body, and the internal pipe fittings are divided into multiple sections, such as the above-mentioned three-section type, so that each section of the pipe fitting can be smoothly installed into the body 3. By setting a positioning surface in the drainage outer opening 31 of the body 3 to fix the internal pipe fittings, the pipe fittings are seamlessly connected to form a complete water flow channel, and there is no water seepage, realizing the use of the integral body 3, improving the aesthetic appearance and structural firmness of the faucet, reducing the production cost, and improving the product safety performance.

[0056] The above specific embodiments are exemplary and are intended to better enable those skilled in the art to understand the present invention, and should not be construed as a limitation on the scope of protection required by the present invention; as long as any equivalent changes or modifications are made according to the spirit disclosed in the present invention, they all fall within the scope of protection required by the present invention.
