[0025] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Example 1

[0026] like Figure 1-Figure 4 As shown, a single cold faucet includes an inner core body 1, the inner core body 1 includes: a valve seat 2, a water inlet pipe 3 and a water outlet pipe 4 arranged on the valve seat 2, a water inlet hole 5 opened on the valve seat 2 and connected with the water inlet pipe 3, and a water outlet hole 6 opened on the valve seat 2 and connected with the water outlet pipe 4. A protective shell 7 is provided on the inner core body 1 through a positioning sealing device. The positioning sealing device includes: an opening 8 opened on the protective shell 7 corresponding to the valve seat 2, and a valve core sleeve 9 inserted in the opening 8. The valve core sleeve 9 is welded at the opening 8 to prevent it from falling off. A sealing device is also provided between the valve core sleeve 9 and the valve seat 2. The valve core sleeve 9 is also provided with a water flow device for controlling the fluid.

[0027] In order to prevent the fluid from leaking from the gap between the valve core sleeve 9 and the valve seat 2, the sealing device includes: an installation groove 10 opened on the valve seat 2 to match the valve core sleeve 9 and located outside the water outlet 6 and the water inlet 5, and a first sealing ring 11 arranged in the installation groove 10. The valve core sleeve 9 is inserted in the installation groove 10 and resists the first sealing ring 11.

[0028] In order to further prevent fluid leakage and play a double sealing role, the valve core sleeve 9 is welded at the opening 8 to further prevent fluid leakage.

[0029] In order to facilitate the rapid alignment of the valve seat 2 and the opening 8, a positioning device for preliminary positioning is further provided between the inner core body 1 and the protective shell 7. The positioning device includes: a limiting ring platform 12 integrally formed on the protective shell 7, and a limiting ring groove 13 provided on the inner core body 1 and located at the outlet pipe 4 for engaging with the limiting ring platform 12;

[0030] The limiting ring 12 is integrally formed on the protective shell 7 through a folding process.

[0031] In order to make the installation of the protective shell 7 smoother, the inner core body 1 is further provided with a guide strip 14 that matches the inner diameter of the protective shell 7 and is used to reduce the friction force when the protective shell 7 is installed.

[0032] In order to facilitate the installation of the faucet, the inner core body 1 is also provided with a connecting device for facilitating the installation of the faucet, and the connecting device includes: a first connecting pipe 15 integrally formed and arranged on the inner core body 1 at the water inlet pipe 3, and a first connecting thread 16 opened on the first connecting pipe 15.

[0033] In order to facilitate the control of the opening and closing state of the fluid, as well as the size of the fluid, the water flow device includes: an installation thread 17 opened on the valve core sleeve 9, a valve core 18 locked on the valve core sleeve 9, and a second sealing ring 19 arranged on the valve core 18 for resisting the end of the valve core sleeve 9.

[0034] In order to enhance the sealing to prevent water leakage and increase the water flow rate, a raised seat 20 is provided on the valve seat 2 around the water inlet hole 5 to resist the bottom of the valve core 18 to reduce the possibility of water leakage, and the water inlet hole 5 and the water outlet hole 6 are not located in the same plane to form a height difference, thereby increasing the water flow rate.

[0035] In order to facilitate the control of the water outlet direction of the faucet, the water outlet pipe 4 is also connected to the faucet bend pipe 21 through a rotating device, and the rotating device includes: a plurality of sealing grooves opened on the faucet bend pipe 21, a third sealing ring 22 sleeved on the sealing groove, a rotating groove opened on the faucet bend pipe 21 and located on the upper side of the third sealing ring 22, a rotating sleeve 23 sleeved on the rotating groove, a resisting ring 24 arranged on the water inlet pipe 3 to resist the rotating sleeve 23, a first positioning hole 25 opened on the rotating sleeve 23, a second positioning hole 26 opened on the inner core body 1, and a positioning pin 27 locked between the first positioning hole 25 and the second positioning hole 26.

[0036] Working principle: During assembly, first put the protective shell 7 on the faucet elbow 21, then fix the faucet elbow 21 in the water inlet pipe 3, and then put the protective shell 7 on the inner core body 1, so that the valve seat 2 corresponds to the opening 8. At this time, install the first sealing ring 11 in the sealing groove, and then insert the valve core sleeve 9 into the valve seat 2 so that it is inserted into the sealing groove and resists the first sealing ring 11. Finally, weld the valve core sleeve 9 and the protective shell 7 to complete the installation between the protective shell 7 and the inner core body 1. Finally, lock the valve core 18 in the valve core sleeve 9 so that the second sealing ring 19 above it abuts against the valve core sleeve 9 to complete the seal.

[0037] During use, the fluid flows from the water inlet pipe 3 through the water inlet hole 5, and then flows into the valve core 18, and then flows out from the valve core 18, overflowing the gap between the valve core sleeve 9, the valve seat 2, and the valve core 18. Since there is a first sealing ring 11 between the valve core sleeve 9 and the valve seat 2, and a second sealing ring 19 between the valve core sleeve 9 and the valve core 18, the fluid will not leak, but will flow to the water outlet 6 after overflowing, and finally flow to the water outlet pipe 4 and the faucet elbow 21 to complete the water outlet. Example 2

[0038] like Figure 5 As shown, based on the technical solution of Example 1, in order to make it easier for users to install the faucet, a connecting device for facilitating the installation of the faucet is also provided on the inner core body 1, and the connecting device includes: a second connecting thread 28 opened on the inner core body 1 at the water inlet pipe 3, a second connecting pipe 29 locked on the inner core body by the second connecting thread 28, and a third connecting thread 30 opened on the second connecting pipe 29.
