Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a faucet connection component and a water outlet faucet. Background Technology

[0002] Existing faucets typically use hollow aluminum alloy shells or solid stainless steel shells. See [link / reference]. Figure 1 The existing zinc alloy shell is hollow and requires multiple additional components to connect to the water outlet pipe, making installation inconvenient. In addition, the zinc alloy shell has a brushed surface treatment, and after the product is formed, it needs to be dimensionally processed. After processing, the shell needs to be polished, followed by ultrasonic cleaning, ultrapure water immersion, nickel plating, brushing, and repainting at an electroplating plant. These processes increase the cost of the shell.

[0003] See Figure 2 As a solid stainless steel faucet, the interior of the shell is a solid water channel, which requires multiple processing steps to form. Furthermore, the solid water channel is in direct contact with water, which may lead to the leaching of heavy metals. In addition, the solid shell structure makes the product heavier and more expensive than the hollow plastic structure. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of existing faucet structures that are inconvenient to install, and to propose a faucet connection component and a water outlet faucet that are easy to install.

[0005] The present invention adopts the following technical solution:

[0007] Furthermore, the connector and the connecting piece are coaxially arranged, and the outer periphery of the connector is fitted with at least one sealing ring to seal against the inner wall of the outlet pipe; the outer periphery of the connecting piece is fitted with at least one sealing ring to seal against the connector.

[0008] Furthermore, the housing includes a main body and a connector; the main body is axially continuous; the connector is welded to one end of the main body in the axial direction and is provided with an axially extending connector portion.

[0009] Furthermore, the main body is provided with an installation port on its side; the housing also includes a sleeve, which is connected to the installation port and welded to fix it; the valve core assembly includes a valve core seat and a valve core, the valve core seat is installed on the end of the sleeve near the connector and is provided with a connecting groove, the valve core is installed in the sleeve and its outlet end is connected to the connecting groove; one end of the connector is threaded to the connecting groove and is connected.

[0010] Furthermore, a first annular groove is provided on the outer periphery of the sleeve, and the mounting port is sleeved on the outside of the first annular groove. The radially extending end face of the first annular groove abuts against the end face of the mounting port for fixing by welding. The valve core assembly also includes a pressure cap, which is sleeved on the end of the sleeve away from the connector and presses the valve core.

[0011] Furthermore, the inner wall of the sleeve is provided with at least one radially extending positioning notch near the end of the connector, and the valve core seat is provided with at least one radially extending protrusion, which is embedded in the corresponding positioning notch to achieve positioning and circumferential fixation.

[0012] Furthermore, the housing also includes a connecting seat, which is welded to the inner wall of the body at the end away from the joint in the axial direction.

[0013] Furthermore, a second annular groove is provided on the outer periphery of the connector; it also includes a bushing, which is located inside the outlet pipe and fitted outside the second annular groove.

[0014] Furthermore, one end of the connector is threaded to the valve core assembly.

[0015] A faucet includes a housing, a water outlet pipe, a water inlet pipe, and a valve core assembly, wherein the valve core assembly is disposed within the housing, and the water inlet pipe is connected to the water inlet end of the valve core assembly; it also includes a connecting component for the faucet described above.

[0016] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this invention, a connector is provided on the housing to insert the water outlet pipe. A connector passes through the connector and one end of it is connected to the valve core assembly. The other end of the connector passes through the connector to serve as an operating part. The operating part protrudes from the connector. By operating the operating part, the connector is connected to the valve core assembly, making the operation very convenient.

[0018] 2. In this invention, the shell is provided with a main body, a connector, a sleeve and a connecting seat. The connector is provided on the connector and the connector is welded to the main body. The main body, connector, sleeve and connecting seat are stamped by steel pipes. The four processed parts are welded into a hollow shell shape, which reduces weight and processing steps, reduces the amount of stainless steel material used, and conforms to the manufacturing trend of low carbon emission reduction.

[0019] 3. In this invention, the stainless steel material itself has anti-corrosion properties, eliminating the need for ultrasonic cleaning, ultrapure water immersion, nickel plating and other complicated processes, thus reducing costs. The hollow one-piece shell structure ensures that the entire shell does not come into contact with the water circuit. The valve core seat and connecting parts made of environmentally friendly polymer materials support the water circuit, effectively preventing the precipitation of heavy metal ions such as chromium and manganese from the stainless steel material.

[0020] 4. In this invention, a positioning notch is provided in the sleeve body, and a corresponding protrusion is provided in the valve core seat. Positioning and circumferential fixing are achieved by the protrusion being embedded in the corresponding positioning notch, ensuring the accuracy of the valve core assembly installation direction and installation position.

[0036] See Figures 3-9 A faucet connection assembly is provided for connecting a housing 10 and a water outlet pipe 20, and for connecting the water outlet pipe 20 and a valve core assembly 30. A connector 14 is provided on the side of the housing 10 opposite to the water outlet pipe 20. The connector 14 is inserted into and sealed with the water outlet pipe 20, meaning the water outlet pipe 20 is sleeved outside the connector 14, and the inner wall of the water outlet pipe 20 and the outer periphery of the connector 14 are sealed together. The assembly also includes a connector 40, which passes through the connector 14. One end of the connector 40 is detachably and fixedly connected to the valve core assembly 30, and the other end of the connector 40 passes through the corresponding end of the connector 14 and is provided with an operating part 41. This operating part 41 facilitates the fixed connection operation between the connector 40 and the valve core assembly 30. The connector 40 also connects the water outlet end of the valve core assembly 30 and the water outlet pipe 20, allowing water output from the water outlet end of the valve core assembly 30 to be delivered to the water outlet pipe 20 via the connector 40.

[0037] The operating part 41 is an axially protruding structure corresponding to the end of the connector 14, allowing for convenient operation of the connector 40, such as rotation. The connector 14 is an axially extending and through-type structure, and the connector 40 is also axially through-type, with the connector 40 and connector 14 being coaxially arranged. At least one sealing ring 18 is fitted around the outer periphery of the connector 14, achieving a sealing fit between the sealing ring 18 and the inner wall of the outlet pipe 20. At least one sealing ring 18 is also fitted around the outer periphery of the connector 40, achieving a sealing fit between the sealing ring 18 and the inner wall of the connector 14.

[0038] The housing 10 includes a main body 11 and a connector 12. The main body 11 is axially continuous. The connector 12 is welded to one end of the main body 11 in the axial direction and has the aforementioned axially extending connector portion 14. In addition to the connector portion 14, the connector 12 also has a connecting portion 13. The connecting portion 13 is located at the end of the main body 11, and the connector portion 14 can be located at the center of the connecting portion 13. The outer periphery of the connecting portion 13 is welded to the end of the main body 11 to form a single unit. The connector portion 14 extends outward along the axial direction of the main body 11 and is located outside the main body 11. When the water outlet pipe 20 is sleeved outside the connector portion 14, the end of the water outlet pipe 20 can contact the end face of the connecting portion 13.

[0039] The main body 11 also has a mounting port 15 on its side, which communicates with the interior of the main body 11. The housing 10 also includes a sleeve 16, which is also a through structure. The sleeve 16 is sleeved and connected to the mounting port 15 and fixed together by welding. The valve core assembly 30 includes a valve core seat 31 and a valve core 32. The valve core seat 31 is installed on the end of the sleeve 16 near the connector 40 and has a communicating groove 33. A sealing ring 18 is fitted around the outer periphery of the valve core seat 31 to seal against the inner wall of the sleeve 16. The inner wall of the sleeve 16 may also have a flange or other structure to prevent the valve core seat 31 from axially disengaging. The valve core 32 is installed inside the sleeve 16 and its outlet end communicates with the communicating groove 33. One end of the connector 40 is threaded into and communicates with the communicating groove 33, that is, the opposite ends of the communicating groove 33 and the connector 40 are respectively provided with threads to achieve threaded engagement.

[0040] The valve core seat 31 has multiple connecting grooves 33, one of which connects the outlet end of the valve core 32 to the connector 40, and at least one connects the inlet end of the valve core 32 to the inlet pipe 50. The valve core assembly 30 may also include a handle 36, which is connected to the control end of the valve core 32 for switching on and off and adjusting the outlet water temperature.

[0041] Furthermore, a first annular groove 16a is provided on the outer periphery of the sleeve 16, and the mounting port 15 is fitted onto the outside of the first annular groove 16a. The radially extending end face of the first annular groove 16a abuts against the end face of the mounting port 15 to fix the sleeve 16 and the main body 11 together by welding. The valve core assembly 30 also includes a pressure cap 35, which is fitted onto the end of the sleeve 16 away from the connector 40 and presses the valve core 32. The pressure cap 35 and the sleeve 16 are threaded together. The preload generated by the threaded connection makes the valve core 32 fit tightly against the valve core seat 31, and at the same time, the valve core assembly 30 is fixed in the direction perpendicular to the axial direction of the housing 10.

[0042] To ensure the accuracy of the installation position and orientation of the valve core seat 31, at least one radially extending positioning notch 34 is provided on the inner wall of the sleeve 16 near the end of the connector 40. The valve core seat 31 is correspondingly provided with at least one radially extending protrusion (not shown in the figure). The protrusion is embedded in the corresponding positioning notch 34 to achieve positioning and circumferential fixation.

[0043] The housing 10 also includes a connecting seat 17, which is welded to the inner wall of the other end of the main body 11 in the axial direction, that is, the end of the main body 11 away from the connector 40 in the axial direction. The inner wall of the connecting seat 17 is provided with threads, which can be used to connect the locking structure 60, etc., to fix the faucet to the countertop. The outer periphery of the connecting seat 17 is welded to the inner wall of the main body 11 to form a whole.

[0044] The shell 10 is made of stainless steel. The main body 11, connector 12, sleeve 16, and connecting seat 17 are stamped from steel pipes. The four processed parts are welded into the hollow shell 10 shape, reducing weight and processing steps, and significantly reducing the use of stainless steel (approximately 58%), which aligns with the trend of low-carbon emission reduction in manufacturing. Furthermore, the surface of the shell 10 utilizes the inherent corrosion resistance of stainless steel to reduce costs, eliminating the need for ultrasonic cleaning, ultrapure water immersion, nickel plating, and other cumbersome processes, meeting national standards. In this invention's hollow integrated shell structure, the entire shell shape does not contact the water passages. Inside the shell 10, components such as the valve core seat 31 and connector 40, made of environmentally friendly polymer materials, support the water passages, effectively preventing the leaching of heavy metal ions such as chromium and manganese from the stainless steel material.

[0045] The present invention further includes a second annular groove 14a on the outer periphery of the connector portion 14, the second annular groove 14a being radially concave; it also includes a bushing 19, the bushing 19 being located inside the water outlet pipe 20 and fitted outside the second annular groove 14a. The bushing 19 is provided to avoid metal-to-metal friction between the connector portion 14 and the water outlet pipe 20.

[0046] During installation, the connecting assembly of the present invention uses the positioning notch 34 and the protrusion to align the valve core seat 31 with the sleeve 16, inserts the valve core assembly 30 into the sleeve 16, and presses it with the pressure cap 35. Then, one end of the connector 40 passes through the connector 14 and is inserted into the communicating groove 33 of the valve core seat 31. The operating part 41 is rotated to tighten the connector 40 with the communicating groove 33. Finally, the water outlet pipe 20 is fitted over the connector 14, completing the connection between the housing 10 and the water outlet pipe 20, as well as the communication between the water outlet pipe 20 and the valve core assembly 30. The solution of the present invention allows for quick and easy fixation and communication of the internal water passages of the housing 10 by directly passing the connector 40 through the connector 14 and tightening it with the operating part 41. This greatly reduces installation time.

[0047] Based on this, see Figures 3-9The present invention also proposes a faucet, including a housing 10, a water outlet pipe 20, a water inlet pipe 50, and a valve core assembly 30, etc. The valve core assembly 30 is disposed inside the housing 10, and the water inlet pipe 50 passes through the locking structure 60 and is connected to the water inlet end of the valve core assembly 30. It also includes the above-mentioned faucet connecting component, which connects the housing 10 and the water outlet pipe 20 and connects the water outlet pipe 20 and the valve core assembly 30.

[0048] The valve core assembly 30 is used to control the opening or closing of the water outlet pipe 20. When the water outlet is opened, the water flows through the inlet pipe 50 into the inlet end of the valve core 32, flows from the outlet end of the valve core 32 into the connector 40, and then flows out from the water outlet pipe 20.

[0049] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
