Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a stainless steel faucet inner core and a stainless steel faucet. Background Art

[0002] The stainless steel faucet consists of a housing tube and a stainless steel valve seat positioned within the tube. The cold and hot water pipes extend into the tube and dock with the valve seat. However, the cold and hot water inlets at the bottom of the valve seat are located far from the bottom of the tube, requiring the cold and hot water pipes to be inserted deeper for docking, making assembly more complex.

[0003] To address this issue, Chinese patent CN203189777U proposes installing extensions, connecting the cold and hot water inlets via two extension tubes, respectively, to facilitate connection between the cold and hot water pipes. However, the thin-walled tubes employed in this design are susceptible to corrosion and leakage after prolonged use. Furthermore, when the extension tubes are pulled horizontally against the cold and hot water pipes, they can easily bend and deform, leading to leaks.

[0004] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

DETAILED DESCRIPTION

[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0041] like Figures 1 to 6 As shown, it is a stainless steel faucet inner core involved in the present invention, including a valve core seat 1 and an extension seat 2, the valve core seat 1 and the extension seat 2 are both made of stainless steel, the upper end of the valve core seat 1 is formed with a valve core end face 11, and the valve core seat 1 is formed with an upper cold water inlet waterway 12, an upper hot water inlet waterway 13 and a mixed water outlet waterway 14 connected to the valve core end face 11; the extension seat 2 is formed with a lower cold water inlet waterway 21 and a lower hot water inlet waterway 22, the upper end of the extension seat 2 is welded to the lower end of the valve core seat 1, the lower cold water inlet waterway 21 is sealed and connected to the upper cold water inlet waterway 12, and the lower hot water inlet waterway 22 is sealed and connected to the upper hot water inlet waterway 13.

[0042] In this way, the utility model relates to a stainless steel faucet inner core and a stainless steel faucet, wherein the lower cold water inlet waterway 21 and the lower hot water inlet waterway 22 are integrally formed in the extension seat 2, and have strong integrity. After the extension seat 2 and the valve core seat 1 are welded, the connection is firm, and the extension seat 2 is not easy to deform or leak.

[0043] Preferably, the valve core seat 1 and the extension seat 2 are both cylindrical, with the diameter of the extension seat 2 being smaller than that of the valve core seat 1. Furthermore, the valve core seat 1 and the extension seat 2 are coaxially arranged. This coaxial arrangement of the extension seat 2 and the valve core seat 1 allows the bottom cover 300 to more conveniently annularly abut the extension seat 2, such that the hollow channel 310 is completely located inside the outer edge of the extension seat 2.

[0044] The valve core seat 1 and the extension seat 2 can be processed by stainless steel cylindrical bars, which have a wide range of raw materials.

A positioning pin 18 is connected between the two opposing positioning holes 17. The two ends of the positioning pin 18 are inserted into the positioning holes 17, thereby positioning the valve core seat 1 and the extension seat 2. After welding, the position of the valve core seat 1 and the extension seat 2 is fixed.

[0049] To further ensure the sealing of the waterways, sealing rings 15 are provided at the connection between the lower cold water inlet channel 21 and the upper cold water inlet channel 12, and at the connection between the lower hot water inlet channel 22 and the upper hot water inlet channel 13. Furthermore, a sink 16 for accommodating the sealing rings 15 is provided at the bottom of each of the upper cold water inlet channel 12 and the upper hot water inlet channel 13.
