[0051] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0052] like Figures 3 to 16 As shown, it is a lifting waterway structure involved in the present invention, including an outer shell 1, a valve core seat 2 and a waterway lifting piece 3, the outer shell 1 includes a shell body 11 and a water outlet pipe 12 connected to the shell body 11, a lifting channel 31 is arranged in the waterway lifting piece 3, and the lifting channel 31 has a water inlet end 311 and a water outlet end 312; the valve core seat 2 has a mixed water outlet hole 21, and the mixed water outlet hole 21 is sealed against the waterway lifting piece 3 and is connected to the water inlet end 311 of the lifting channel 31; the side of the waterway lifting piece 3 facing away from the valve core seat 2 is sealed against the inner wall of the shell body 11, and the water outlet end 312 of the lifting channel 31 is connected to the water outlet pipe 12; the connection point between the water outlet pipe 12 and the water outlet end 312 is higher than the height of the water inlet end 311 in the vertical direction.

[0053] In this way, the present invention relates to a lifting type water channel structure, by providing the water channel lifting piece 3, the water flowing out of the mixed water outlet 21 is lifted through the lifting channel 31, and is connected to the water outlet pipe 12 through the water outlet end 312. In this way, the position where the water outlet pipe 12 is connected to the shell body 11 is lifted compared to the traditional faucet, and the space for users to use at the bottom of the water outlet pipe 12 is increased. At the same time, the limitation of the traditional faucet on the connection position of the water outlet pipe 12 and the shell body 11 is eliminated, making the shape design of the water outlet pipe 12 more flexible. Preferably, a water hose is provided in the water outlet pipe 12, and the water hose is connected to the water outlet end 312. In this way, the water flow can be prevented from directly contacting the water outlet pipe 12, thereby avoiding contamination of the water flow.

[0054] The setting of the lifting water channel enables the water outlet end 312 of the lifting piece to lift the water flow to a height exceeding the bottom of the valve core. At the same time, since the two ends of the water channel lifting piece 3 are respectively sealed with the valve core seat 2 and the inner wall of the shell body 11, the water flow will not leak to the space between the valve core seat 2 and the shell body 11 to cause water accumulation. That is, it is not easy to cause water impurities to be deposited in the shell body 11 and the shell body 11 to freeze and crack in winter.

[0055] Preferably, the valve core seat 2 and the water channel lifting piece 3 are both provided with an inclined abutting surface 4, and the valve core seat 2 abuts against the water channel lifting piece 3 from bottom to top through the inclined abutting surface 4; the mixed water outlet 21 and the water inlet end 311 are respectively formed on the inclined abutting surfaces 4 of the valve core seat 2 and the water channel lifting piece 3. The valve core seat 2 and the water channel lifting piece 3 are matched with the inclined abutting surface 4. As the valve core seat 2 abuts upward, the pressing force between the valve core seat 2 and the water channel lifting piece 3 increases, and at the same time, the pressing force between the water channel lifting piece 3 and the shell body 11 is tighter. The sealing effect is guaranteed. Preferably, the angle between the inclined abutting surface 4 and the vertical direction is 20 degrees.

[0056] Preferably, the valve core seat 2 has an upper end seat 22, and the upper end of the upper end seat 22 is provided with a hot water inlet hole 221, a cold water inlet hole 222 and a water through hole 223 connected to the mixed water outlet hole 21; the upper end of the upper end seat 22 is provided with an upwardly extending extension seat 23, and the extension seat 23 is provided with an auxiliary top-butting surface 5 coplanar with the inclined top-butting surface 4 on the valve core seat 2; the auxiliary top-butting surface 5 abuts on the waterway lifting piece 3; the extension seat 23 and the waterway lifting piece 3 enclose a valve core placement cavity with an upper end opening. By providing the extension seat 23, the abutment between the valve core seat 2 and the waterway lifting piece 3 is made more secure and stable. The lower end of the valve core is placed on the upper end seat 22 and is located in the valve core placement cavity, and is sealed and connected with the hot water inlet hole 221, the cold water inlet hole 222 and the water through hole 223 to adjust the outlet water temperature. Furthermore, arc chamfers 28 are provided on the valve core seat 2 on the left and right sides of the mixed water outlet 21. The arc chamfers 28 can make the inclined top surface 4 on the valve core seat 2 better fit with the waterway lifting piece 3, reducing the interference caused by the lower edge of the inclined top surface 4 of the valve core seat 2 and the inner wall of the shell body 11 of the faucet shell or the waterway lifting piece 3 affecting the top sealing effect. Preferably, a reinforcing rib 232 is formed on the upper edge of the extension seat 23 to increase the structural strength of the extension seat.

[0057] Preferably, a limiting slide groove 231 is provided in the middle of the upper end of one side of the extension seat 23 close to the shell body 11, and a vertical fixing block 112 cooperating with the limiting slide groove is provided on the inner wall of the shell body 11, and the limiting slide groove 231 can slide up and down on the vertical fixing block 112. When the valve core seat 2 and the waterway lifting piece 3 abut against each other through the inclined abutting surface 4 and the auxiliary abutting surface 5, the limiting slide groove 231 and the vertical fixing block 112 cooperate with each other, so that the valve core seat 2 and the waterway lifting piece 3 can be accurately aligned, preventing the valve core seat 2 from deviating around the vertical axis.

[0058] Preferably, the valve core seat 2 also has a hot water pipe 24 connected to the hot water inlet hole 221 and a cold water pipe 25 connected to the cold water inlet hole 222.

The external water supply pipe is respectively connected to the cold water pipe 25 and the hot water pipe 24 to achieve water supply. The abutting block 113 is threadedly connected to the shell body 11 and can abut against the cold water pipe 25 and the hot water pipe 24. As the abutting block 113 rotates and abuts, the abutment between the valve core seat 2 and the waterway lifting piece 3 becomes tighter.

[0059] Preferably, a placement groove 32 is formed in a recessed manner at one end of the water channel lifting piece 3 facing the valve core seat 2, and a step surface 321 is formed at the bottom of the placement groove 32. The water inlet end 311 of the lifting channel 31 is lower than the step surface 321, and the upper end of the water outlet end 312 of the lifting channel 31 is higher than the step surface 321.

The first sealing ring 27 improves the sealing effect between the valve core seat 2 and the waterway lifting piece 3 around the mixed water outlet hole. The first sealing ring 27 is deformed when the valve core seat 2 and the waterway lifting piece 3 abut against each other, so that it has a better sealing effect. The first sealing ring 26 is embedded in the first annular groove 26, which ensures the fixing effect of the first sealing ring 27.

[0062] Preferably, as a second embodiment of the present invention, a limiting protrusion 33 is provided on the surface of the waterway lifting piece 3 that abuts against the shell body 11, and the water outlet end 312 of the lifting channel 31 is provided on the limiting protrusion 33; a limiting groove 116 that cooperates with the limiting protrusion 33 is formed on the inner wall of the shell body 11, and the limiting protrusion 33 is embedded in the limiting groove 116. The waterway lifting piece 3 is preliminarily connected to the inner wall of the shell body 11 through the limiting protrusion 33, so as to facilitate the subsequent sealing connection between the valve core seat 2 and the waterway lifting piece 3 after abutting against each other.

[0063] Compared with the second embodiment of the waterway lifting piece 3, the first embodiment of the waterway lifting piece 3 has the characteristics of convenient processing and low processing precision requirements.

[0064] Preferably, a second sealing ring 35 is provided on the limiting protrusion 33 on the outer periphery of the water outlet end 312 of the lifting channel 31, and a second annular groove 34 for accommodating and limiting the second sealing ring 35 is formed on the limiting protrusion 33. The second sealing ring 35 is embedded in the first annular groove 26, and when abutment occurs, the second sealing ring 35 is deformed, thereby improving the sealing effect.

In the embodiment with an inclined abutting surface 4, when the waterway lifting piece 3 abuts against the valve core seat 2, the first abutting surface 115 gives the waterway lifting piece 3 a downward abutting force.

[0066] Preferably, the first sealing ring 27 and the second sealing ring 35 are both made of silicone.
