[0029] Reference Figure 1-5 As shown, a metal water outlet structure for a shower faucet includes a small metal tube 1, a large metal tube 2, and a metal connector 3. One end of the small metal tube 1 and the large metal tube 2 is provided with a sealing plate 11. The small metal tube 1 has several water outlet holes 12 along its length on its side. The large metal tube 2 has a water outlet interface 21 on its side near the sealing plate 11. The metal connector 3 is welded and fixed to the water outlet interface 21. Both the open end of the large metal tube 2 and the metal connector 3 have internal threads. The threaded end of the large metal tube 2 is provided with a first valve chamber 22. A through insertion hole 23 is provided between the water outlet interface 21 and the open end of the large metal tube 2. Several insertion holes 23 of the large metal tube 2 are welded and fixed to the small metal tube 1, and the water outlet holes 12 are correspondingly located inside the large metal tube 2. A sealing gasket 4 and a valve core seat 5 are provided at each water outlet hole 12. The valve core seat 5 is sealed and connected to the water outlet hole 12 through the sealing gasket 4.

[0030] The water outlet structure of this application consists of a small metal tube 1 and a large metal tube 2. A sealing plate 11 is provided at one end of the small metal tube 1 and the large metal tube 2. The sealing plate 11 can be a metal part or a plastic part. The metal part can be connected by welding or threaded connection, and the plastic part can be connected by threaded connection.

[0031] The side of the small metal tube 1 has several water outlet holes 12 along its length. The number of water outlet holes 12 can be determined according to the required number and can be obtained by drilling or cutting, such as by drilling machine, cutting machine, laser cutting, etc. The side of the large metal tube 2 near the sealing plate 11 has a metal connector 3 for connecting a shower head or faucet. The middle section of the large metal tube 2 has a through insertion hole 23. The large metal tube 2 is fitted into the water outlet hole 12 of the small metal tube 1 through the insertion hole 23 and is connected to the small metal tube 1 by welding to ensure connection strength and sealing. The valve core seat 5 is sealed and connected to the water outlet hole 12 through a sealing gasket 4. One end of the sealing gasket 4 matches the water outlet hole 12 of the small metal tube 1, and the other end is connected to the valve core seat 5. The sealing gasket 4 realizes the connection between the water outlet hole 12 and the standard valve core seat 5. The outlet pipe of the valve body in this application is made of welded metal parts. The large metal pipe 2 is sleeved on the small metal pipe 1, and connected to the existing standard valve core seat 5 through the sealing gasket 4, so that the water circuit can be controlled by the valve core.

[0032] This design avoids the need for mold manufacturing and high R&D and production costs associated with integral valve body structures obtained through injection molding or die casting. Furthermore, the use of a large and small pipe interlocking method simplifies assembly and processing. Welding ensures connection strength and excellent sealing, eliminating the need for additional sealing rings for waterproofing. In contrast, the interlocking method for large and small pipes presents challenges in setting up sealing rings, which can easily shift during assembly, leading to leakage. Especially with the metal pipe body used as the main component, the sharp edges of the metal can damage the seals during assembly, increasing installation difficulty, reducing yield, and hindering product assembly. Conversely, the movable interlocking method is also prone to displacement during assembly, resulting in inconsistent product quality and making quality control difficult.

[0033] The above design achieves the characteristics of simple structure, convenient manufacturing, simple process, reduced cost, low price, small tube thickness, small overall volume, and space saving.

[0034] Furthermore, the water outlet 21 and the insertion hole 23 are respectively located on the vertical surface of the metal pipe 2.

[0035] The large metal pipe 2 is arranged side by side on the small metal pipe 1, and the metal connector 3 is located on the upper or lower side of the large metal pipe 2 for easy connection to the spray head or water outlet. For example, the upper metal connector 3 is connected to the overhead spray, and the two lower metal connectors 3 are connected to the lower water outlet (aerated water) and the handheld shower head, respectively.

[0036] Furthermore, the insertion hole 23 is provided through the axis of the metal tube 2 or near the side of the water outlet 21.

[0037] The insertion hole 23 is set through the axis of the metal tube 2, which facilitates processing and subsequent assembly operations.

[0038] The insertion hole 23 is positioned on the side near the water outlet 21, which increases the distance between the inner walls of the small metal tube 1 and the large metal tube 2 on the side away from the insertion hole 23. Furthermore, the outlet of the valve core is also positioned on the opposite side of the insertion hole 23, allowing the water to flow directly to the opposite side of the insertion hole 23 and then into the metal connector 3. This prevents water from flowing directly or excessively into the insertion hole 23, which would cause the water flow to be perpendicular to the water outlet direction of the metal connector 3, resulting in significant turbulence and reducing the flow velocity.

[0039] Furthermore, the sealing gasket 4 is a rubber gasket, and the sealing gasket 4 has a water passage hole 41 in the center. One end of the sealing gasket 4 is connected to the water outlet hole 12 and is sealed to the metal tube 1. The other end of the sealing gasket 4 is matched and connected to the valve core.

[0040] The sealing gasket 4 serves to match the water outlet 12 and the valve core seat 5, and also provides a seal, allowing water to flow smoothly from the metal tube 1 through the valve core seat 5 into the valve core, thus achieving on / off control. The structure of the sealing gasket 4 can be adjusted according to the positional relationship between the water outlet 12 and the valve core seat 5, and between the valve core seat 5 and the valve core, to achieve both flow guidance and sealing.

[0041] Furthermore, both the large metal tube 2 and the small metal tube 1 are round tubes, and the sealing gasket 4 matches the arc shape of the connection section with the water outlet 12.

[0042] Round pipes are easy to process, provide good water flow, and are aesthetically pleasing.

[0043] Furthermore, at least the metal tube 1 of the large metal tube 2 and the small metal tube 1 is a square tube.

[0044] It is easy to process and easy to assemble, but the water flow effect is poor.

[0045] Furthermore, the large metal tube 2 and the small metal tube 1 are stainless steel tubes, and the sealing plate 11 is welded or threaded to the large metal tube 2 and the small metal tube 1.

[0046] The large metal tube 2 and the small metal tube 1 can be made by cutting and welding existing stainless steel tubes, which is easy to obtain and has low processing difficulty.

[0047] Reference Figure 1-7 As shown, a shower faucet valve body includes a mixing valve seat 6, a cold water pipe 7, a hot water pipe 8, a water inlet connector 9, and the aforementioned water outlet structure. The mixing valve seat 6 is provided with a cold water inlet 61, a hot water inlet 62, a water outlet 63, and a second valve chamber 64. The cold water inlet 61 and the hot water outlet are located at one end of the mixing valve seat 6 and communicate with the second valve chamber 64 located at the other end. The water outlet 63 is located on the side of the mixing valve seat 6 and communicates with the second valve chamber 64. The small metal tube 1 of the water outlet structure is connected to the water outlet 63.

[0048] The mixing valve seat 6, cold water pipe 7, hot water pipe 8, and inlet connector 9 can be made of metal and connected to each other by welding or threading, and to the outlet structure by welding or threading, or by interference fit. The mixing valve seat 6, cold water pipe 7, hot water pipe 8, and inlet connector 9 can also be conventional injection molded or die-cast parts and connected to the outlet structure by threading or plugging.

[0049] Finally, assemble the valve body and valve core into the storage box. The two connectors face downwards; one connects to the bottom water outlet (aerated water), and the other connects to the hand shower head. The mixing valve core is normally placed on the right. According to control requirements, the left side is generally the cold water pipe 7, and the right side is the hot water pipe 8.

[0050] Furthermore, the cold water pipe 7, hot water pipe 8, and water outlet structure are plugged into or threadedly connected to the corresponding interfaces of the mixing valve seat 6.

[0051] Furthermore, the mixing valve seat 6, cold water pipe 7, and hot water pipe 8 are all metal parts, and the mixing valve seat 6 is connected to the cold water pipe 7, hot water pipe 8, and water outlet structure by welding.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
