[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0054] Please refer to Figures 1, 2, 3, 4, and 5, which illustrate a first embodiment of the water outlet device of a split-type faucet according to the present invention. The water outlet device includes a riser 1, a water outlet pipe 2, a locking pipe 3, an inner pipe 4, a valve core 6, and a water inlet pipe 7. The riser 1 is vertically mounted on the countertop and is a columnar structure with openings at both ends. A through hole 12 is provided on the side wall of the riser 1 near its upper opening 11. The water outlet pipe 2 includes an inlet end 21 at one end and a water outlet end at the other end, and is arranged perpendicular to the axis of the riser 1. The locking pipe 3 is used to lock and connect the inlet end 21 of the water outlet pipe 2 and the through hole 12 on the side wall of the riser 1. The inner pipe 4 is installed inside the riser 1 and is a tubular structure. The axis of the inner pipe 4 coincides with the central axis of the riser 1, and an annular channel 5 for fluid passage is provided between the outer side wall of the inner pipe 4 and the inner side wall of the riser 1. The valve core 6 is coupled to the upper part of the inner tube 4. The valve stem of the valve core 6 extends from the upper opening of the inner tube 4 to facilitate connection between the valve stem and the handle 8. The water inlet at the lower end of the valve core 6 is connected to two water inlet pipes 7, which are respectively a hot water inlet pipe and a cold water inlet pipe. The water outlet on the side wall of the valve core 6 is connected to two water outlet holes 41 provided on the side wall of the inner tube 4. The water outlet device of this embodiment adopts a split structure, which is simple in design, easy to assemble, and has low production cost.

[0055] When in use, adjust handle 8 to open valve core 6. Cold water and hot water enter valve core 6 from two inlet pipes 7 respectively. Mixed water flows from the outlet of valve core 6 through two outlet holes 41 on the side wall of inner pipe 4, enters annular channel 5, locking pipe 3 and outlet pipe 2, and flows out from the outlet end of outlet pipe 2.

[0056] As shown in Figures 4, 5, 6, 7, and 8, the locking tube 3 has a pipe hole for fluid passage and includes a threaded section 31, a sealing section 34, and an annular boss 32. The threaded section 31 is arranged axially along the locking tube 3. At one end of the threaded section 31, an annular boss 32 extends radially along the locking tube 3. At the other end of the threaded section 31, a sealing section 34 extends axially along the locking tube 3. A first annular groove 35 is provided at the connection between the threaded section 31 and the annular boss 32, and a first O-ring seal 15 is embedded in the first annular groove 35. Two second annular grooves 36 are sequentially provided on the sealing section 34, and second O-ring seals 16 are embedded in the second annular grooves. The outer diameters of the sealing section 34, the threaded section 31, and the annular boss 32 increase sequentially and are integrally formed. Near the annular boss 32, a wrench 33 is provided on the inner wall of the locking tube 3's bore, along the axial direction of the locking tube 3. The wrench 33 has an internal polygonal structure, such as a triangle or hexagon, preferably an internal hexagon. The internal hexagonal wrench 33 cooperates with a hexagonal wrench, which rotates the locking tube. In a further improvement, an annular guide slope 37 is provided on the outer side of the wrench 33 in the locking tube 3's bore. The guide slope 37 facilitates the insertion of the hexagonal wrench into the wrench 33 of the locking tube 3.

[0057] When assembling the riser 1, outlet pipe 2, and locking pipe 3, the locking pipe 3 is placed in the inner cavity of the riser 1 through the upper opening 11, so that the sealing section 34 and threaded section 31 of the locking pipe 3 protrude outward from the through hole 12 of the riser 3. Since the outer diameter of the annular boss 32 of the locking pipe 3 is larger than the diameter of the through hole 12 of the riser 1, the annular boss 32 of the locking pipe 3 will not come out of the through hole 12 of the riser 1. The threaded section 31 of the locking pipe 3 is threadedly connected to the screw hole 23 on the inlet end 21 of the outlet pipe 2. When the wrench tool enters from the upper opening 11 of the riser 1 and is aligned with the wrench mouth 33 of the locking pipe 3, the wrench tool is rotated, causing the locking pipe 3 to rotate as a whole, so that the threaded section 31 of the locking pipe 3 is threadedly connected to the screw hole 23 on the inlet end 21 of the outlet pipe 2 and locked. When the threaded section 31 of the locking tube 3 is tightened into the threaded hole 23 on the inlet end 21, the first O-ring 15 in the first annular groove 35 seals the locking tube 3, the riser 1, and the outlet pipe 2. Specifically, the inner ring of the first O-ring 15 abuts against the inner wall of the first annular groove 35, the outer ring of the first O-ring 15 abuts against the inner wall of the outlet pipe 2, and both sides of the first O-ring 15 abut against the side wall of the annular boss 32 of the locking tube 3 and the side wall of the first annular groove 35, respectively. After the sealing section 34 of the locking tube 3 passes through the threaded hole 23 of the outlet pipe 2, it is fitted and connected to the inner wall of the outlet pipe 2. To ensure the sealing of the sealing section 34 of the locking pipe 3 and the inner wall of the outlet pipe 2, two second O-rings 16 are respectively provided in the two second annular grooves 36 on the sealing section 34 of the locking pipe 3. The inner ring of the second O-ring 16 abuts against the inner wall of the second annular groove 36, and the outer ring of the second O-ring 16 abuts against the inner wall of the outlet pipe 2. The provision of two second O-rings 16 enhances the sealing performance.

[0058] Unlike existing technologies, the outlet pipe 2 and the riser 1 are locked and connected by the locking pipe 3, which has a simple structure and is easy to assemble. The function of the locking pipe 3 is to solve the problem of fixing the outlet pipe 2 and the riser 1, and to solve the problem of connecting the outlet pipe 2 and the riser 1 to realize the flow of water.

[0059] As shown in Figures 5 and 9, the water outlet pipe 2 is further improved. In order to better connect the water inlet end 21 of the water outlet pipe 2 with the water outlet pipe 2, the water inlet end 21 of the water outlet pipe 2 is set as a concave arc-shaped end face 24. The arc-shaped end face 24 of the water inlet end 21 of the water outlet pipe 2 is adapted to the arc-shaped outer wall of the riser pipe 1. The connection between the water outlet pipe 2 and the riser pipe 1 is more secure, and the water outlet pipe 2 and the riser pipe 1 are less likely to rotate relative to each other. The gap at the connection is small, which enhances the aesthetics.

[0060] As shown in Figures 1, 2, 3, 10, 11, and 12, the valve core 6 is coupled to the upper part of the inner tube 4. The valve stem of the valve core 6 extends from the upper opening of the inner tube 4. A locking nut 18 is provided at the upper end of the valve body 6, and the external thread of the locking nut 18 is threadedly connected to the internal thread 13 provided at the upper end of the riser 1. A third O-ring seal 17 is provided between the inner wall of the inner tube 4 and the lower outer side of the valve core 4, sealing the lower part of the valve core 6 and the inner tube 4. The water inlet at the lower end of the valve core 6 is connected to two water inlet pipes 7, while the water outlet of the valve core 6 is connected to the annular channel 5 through two water outlet holes 41 on the inner tube 4. It should be noted that an annular groove 42 is provided on the outer wall of the inner tube 4, and the annular groove 42 is connected to the two water outlet holes 41 on the inner tube 4, thus facilitating rapid water flow between the two water outlet holes 41 on the side wall of the inner tube 4. To further increase the water flow rate, both water outlets 41 on the inner pipe 4 are kidney-shaped water outlets.

[0061] The advantages of this embodiment 1 are: by setting a locking tube to connect and communicate the water outlet pipe with the riser, the water outlet pipe can be disassembled separately. When the water outlet pipe is damaged, it can be replaced separately. The structure is simple and the installation and disassembly are very convenient. The water outlet pipe is provided with an arc-shaped fitting end face, so that the water outlet pipe can fit tightly with the riser body, which is more aesthetically pleasing. The split design structure allows different materials to be used for different parts, which meets the national standard requirements for faucets. Example 2

[0062] Please refer to Figures 13, 14 and 15, which show the second embodiment of the water outlet device of the split-type faucet of the present invention. The main difference between the second embodiment and the first embodiment is that the riser 1 is a square tube structure, the water inlet end face of the water outlet pipe 2 is a planar structure, the side wall of the riser 1 is a plane, the planar side wall of the riser 1 abuts against the water inlet end face of the water outlet pipe 2, and is locked and connected by the locking pipe 3.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
