Water route promotion sheet and inner core body are combined in the shell body in turn, sealing ring one relies on the mutual resistance tightness between water route promotion sheet and inner core body, sealing ring two relies on the mutual resistance sealing between water route promotion sheet and shell body. Under the tension of two sealing rings, water route promotion sheet, inner core body and shell body have both horizontal resistance and longitudinal resistance during assembly process, and the assembly efficiency is low, and sealing ring one and sealing ring two are prone to curling deformation under the installation resistance, which affects the sealing effect and the stable use of the faucet.

[0003] In order to solve the above problems, the case is generated. CONTENT OF THE UTILITY MODEL

[0004] Therefore, in view of the above problems, the utility model provides a water route promotion combination core body and a faucet assembly with the combination core body to solve the problems of inconvenient assembly and poor sealing in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following solution: a water route promotion combination core body, comprising an inner core body, the lower end of the inner core body is a water inlet pipeline, and the upper end is a valve core installation cavity, a water inlet hole and a water outlet hole are formed in the bottom of the valve core installation cavity and communicate with the water inlet pipeline, characterized in that: a water route promotion groove is formed in the outer wall of the upper end of the inner core body on one side in the longitudinal direction, a water outlet is formed in the bottom of the water route promotion groove and communicates with the water route promotion groove, a horizontal channel is arranged in communication between the water outlet and the water outlet hole in the bottom surface of the valve core installation cavity, an annular sealing groove is formed in the outer wall of the valve core installation cavity on the side of the water route promotion groove, and a split section is arranged on the upper end of the inner core body and inclined outward and downward from the top of the inner core body, the split section divides the other side of the upper end of the inner core body in the water route promotion groove into a convenient assembly split block, and the split section passes through the bottom surface of the valve core installation cavity, so that a limiting plane is formed on the inner side of the upper end of the convenient assembly split block to limit the upward movement of the convenient assembly split block.

[0006] A further improvement is that the inner core is integrally provided with a first stabilizing protrusion for increasing the installation stability of the portable modular block below the valve core mounting cavity. The first stabilizing protrusion is provided with a first inclined surface that is located on the same plane as the modular cross-section. The lower end of the portable modular block extends downward and is provided with a second stabilizing protrusion. The second stabilizing protrusion is provided with a second inclined surface that fits against the first inclined surface, so that the lower end of the portable modular block forms a pointed tip that is easy to insert and assemble.

[0007] A further improvement is that the top of the water outlet is in the shape of a straight line, and the shape below the top is consistent with the lower end of the water channel lifting trough.

[0008] A further improvement is that the cross-sectional shape of the horizontal channel is consistent with the shape of the outlet.

[0009] A further improvement is that the arc-shaped outer wall of the portable modular unit is provided with a positioning groove along the longitudinal direction to cooperate with the positioning of the outer shell.

[0010] A further improvement is that the inner wall of the annular sealing groove extends beyond the outer wall.

[0011] A further improvement is that the outer wall of the upper end of the inner core and the outer wall of the portable modular block are both provided with material-saving grooves that are recessed inward.

[0012] A further improvement is that a positioning block is integrally or separately provided at the bottom of the inner core.

[0013] A further improvement is that the inner diameter of the housing decreases from bottom to top.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0015] In existing technologies, the water channel lifting structure is set up as a separate component, requiring sealing rings between the separate block and the inner core and shell. The tension of these two sealing rings increases assembly resistance, affecting assembly efficiency, and the assembly resistance can easily force the sealing rings to deform and curl, affecting the sealing effect. In this design, the water channel lifting channel is integrated into the inner core, and the portable separate block is located on the other side of the water channel lifting channel. This allows the portable separate block to not participate in water transport; only a single sealing ring between the inner core and shell is needed to achieve water channel sealing. This simplifies the core structure assembly, and using a single sealing ring reduces assembly resistance, improving ease of assembly. During the fitting and assembly process, the portable separate block exerts only a horizontal force, pushing the sealing ring against the inner wall of the shell, without any longitudinal force that could cause curling or deformation of the sealing ring. This improves the sealing effect and facilitates the installation of the inner core, portable separate block, and shell, enhancing installation convenience and efficiency.

[0016] The portable split unit can be restricted from detaching from the housing by the inward protrusion at the upper port of the housing, or it can be directly restricted from detaching from the housing by fixing the water valve core, so as to increase the versatility of the combined core.

[0017] Further beneficial effects are: the setting of the first stabilizing protrusion and the first inclined surface increases the contact area after the portable modular block and the inner core are fitted together, improving the longitudinal stability of the portable modular block after installation. In addition, the corresponding second stabilizing protrusion and the second inclined surface on the portable modular block make the lower end of the portable modular block a pointed tip that is easy to insert into the assembly space between the inner core and the inner wall of the shell, which facilitates the quick insertion and fitting of the portable modular block and improves installation efficiency.

[0018] Further beneficial effects include: the shape of the water outlet is adapted to the shape of the lower end of the water channel lifting trough, and the shape of the horizontal channel is adapted to the shape of the water outlet, which is conducive to the mold manufacturing of the inner core and the forming process of the inner core.

[0019] Further beneficial effects include: the positioning grooves set on the portable modular blocks facilitate the positioning and installation of the portable modular blocks on the shell, while limiting the deflection displacement of the portable modular blocks. This helps to limit the deflection of the inner core by using the portable modular blocks, thereby improving the assembly position accuracy of the water channel lifting channel and the shell outlet.

[0020] A further beneficial effect is that the thickness of the sealing ring is greater than the depth of the annular sealing groove, and the inner wall of the annular sealing groove is set to extend beyond the outer wall, so as to increase the contact area between the inner groove wall and the inner wall of the sealing ring and prevent the sealing ring from deforming during the assembly process.

The inner diameter of the housing 9 decreases from bottom to top. The inner core 10 is installed inside the housing 9. A lower mounting ring 7 is provided at the lower end of the housing 9 to abut and restrict the inner core from detaching downward from the housing 9. The lower end of the inner core 10 is a hot or cold water inlet pipe 11, and the upper end is a valve core mounting cavity 12. A positioning block 13 for restricting the movement and rotation of the inner core 10 is integrally or separately provided at the bottom of the inner core 10. A lower positioning strip 4 is provided longitudinally on the inner wall of the lower end of the housing 9 to slide and cooperate with the positioning block. The inner core 10 has a longitudinally extending elongated water channel lifting groove 14 on one side of its upper outer wall, which closes with the inner wall of the outer shell 9 to form a lifting water channel. An annular sealing groove 15 surrounds the water channel lifting groove 14 for installing a sealing ring 8 to improve the sealing performance of the lifting water channel. The sealing ring 8 is installed within the annular sealing groove 15, and the thickness of the sealing ring 8 is greater than the depth of the annular sealing groove 15. The inner wall 151 of the annular sealing groove 15 extends beyond the outer wall, and the thickness of the sealing ring 8 is greater than the depth of the annular sealing groove 15. An outlet 16 communicating with the bottom of the water channel lifting groove 14 is provided. A horizontal channel 17 connects the outlet 16 to the mixing outlet 124 on the bottom surface of the valve core mounting cavity 12. The top of the outlet 16 is straight, and its lower part is the same shape as the lower end of the water channel lifting groove 14. The cross-sectional shape of the horizontal channel 17 is the same as that of the outlet 16. This facilitates the mold manufacturing of the inner core 10 and the forming process of the inner core 10. The sealing ring 8, which extends beyond the annular sealing groove 15, presses against the inner wall of the housing 9. The water inlet end of the water outlet pipe of the housing 9 is located inside the sealing ring 8 and at the top of the water channel lifting groove 14.

[0037] The upper end of the inner core 10 is provided with a split section 18 that slopes outward and downward from the top of the inner core 10. The split section 18 splits the upper end of the inner core 10 on the other side of the water channel lifting groove 14 to form a portable split block 19. The split section 18 passes through the bottom surface 121 of the valve core mounting cavity 12, so that the inner side of the upper end of the portable split block forms a limiting plane 191 for the bottom surface of the external valve core to abut against and restrict the upward movement of the portable split block 19. The upper port of the housing 9 is provided with an inwardly protruding abutment protrusion 6 for abutting and restricting the inner core and portable split block from detaching upward from the housing 9.

[0038] The inner core 10 is integrally provided with a first stabilizing protrusion 20 below the valve core mounting cavity 12 to increase the installation stability of the portable modular block 19. The first stabilizing protrusion 20 is provided with a first inclined surface 21 located on the same plane as the modular cross section 18. The lower end of the portable modular block 19 extends downward and is provided with a second stabilizing protrusion 22. The second stabilizing protrusion 22 is provided with a second inclined surface 23 that fits against the first inclined surface 21, so that the lower end of the portable modular block 19 forms a pointed tip that is easy to insert and assemble.

[0039] The outer wall of the casual clothing modular block 19 has a longitudinally formed positioning groove 24 that engages with the outer shell 9. The inner wall of the upper end of the shell 9 has a longitudinally protruding upper positioning strip 5 that slides and engages with the positioning groove. The outer wall of the upper end of the inner core 10 and the outer wall of the casual clothing modular block 19 are both recessed inwards with material-saving grooves 25.

[0040] A method for assembling a faucet assembly with a water-lifting core and a housing 9: The housing 9 is tilted, and the positioning groove on the portable modular block is aligned with the upper positioning strip 5 on the inner wall of the housing 9 and slid into the upper end of the housing 9. The positioning block at the lower end of the inner core is aligned with the lower positioning strip 4 on the inner wall of the housing 9 and pushed into the housing 9. Then, the lower mounting ring 7 is screwed onto the lower port of the housing 9. As the lower mounting ring 7 rotates upward, the inner core is pushed upward, causing the top of the inner core to abut against the abutment protrusion 6 at the upper port of the housing 9. During the upward abutment of the inner core, the portable mounting block gradually increases the clamping force on the sealing ring 8 within the annular sealing groove. Furthermore, the inner wall of the housing 9 is wider at the bottom and narrower at the top, which further enhances the sealing effect between the core assembly and the inner wall of the housing 9.

[0041] Based on the above description, when the faucet assembly is a mixing faucet assembly, the inlet pipe 11 consists of two independent channels, which are respectively connected to the two inlet holes at the bottom of the valve core mounting cavity 12, see... Figure 1 , Figure 11 When the faucet assembly is a single-cooling faucet assembly, the water inlet pipe 11 is a single channel, simultaneously connected to the two water inlet holes at the bottom of the valve core mounting cavity 12, see... Figure 13 , Figure 14 .
