[0032] Compared with the background technology, this technical solution has the following advantages:

[0033] 1.

[0034] 2. The water purification pipe body can enter the groove from the lateral opening of the groove and the water purification joint is against the bottom of the groove to prevent the water purification pipe from coming out of the shell body, so that the water purification pipe always remains in the position corresponding to the lateral window.

[0035] 3. During the upward movement of the main body core, it is first guided by the sliding cooperation between the first guide surface and the second guide surface to ensure that the clean water connector is directly opposite to the clean water outlet channel. When the clean water connector and the clean water outlet channel are connected, the first axial limit surface and the second axial limit surface are exactly opposite to each other in axial limit cooperation to limit the continued upward movement of the main body core.

[0036] 4. The second circumferential limiting surface can cooperate with the first circumferential limiting surface to limit the circumferential movement of the body core, and further limit the position of the body core to ensure accurate correspondence of the position of the body core.

[0037] 5. The outer side of the strength reinforcement member forms the step surface, and the bottom end of the collar is pressed against the step surface. The strength reinforcement member can increase the strength of the body core and improve its service life.

[0038] 6. The water purification pipe body is against the outer arc surface of the inner circumference of the bent pipe, and the tap water outlet hose is against the inner arc surface of the inner circumference of the bent pipe, so that the water purification pipe body and the tap water outlet hose are independent of each other and do not affect or interfere with each other, thereby ensuring that the tap water outlet hose can be pulled out freely.

[0054] In this embodiment, the positioning portion includes two positioning pieces 13 arranged opposite to each other, and a through groove 14 with upper and lower ends penetrating and lateral openings is formed between the two positioning pieces 13. The water purification pipe includes a water purification pipe body 40 and a water purification connector 41 fixed to the end of the water purification pipe body 40. The water purification pipe body 40 can enter the through groove 14 from the lateral opening of the through groove 14, and the water purification connector 41 is against the bottom of the through groove 14.

[0055] In this embodiment, the spacing of the lateral openings of the through groove 14 is less than or equal to the diameter of the water purification pipe body 40, and the water purification pipe body 40 is squeezed into the through groove 14 through its own elastic deformation; and the size of the water purification connector 41 is larger than the size of the through groove 14.

[0056] In this embodiment, the distance between the two positioning pieces 13 gradually increases from the center of the shell body 11 to the inner circumference of the shell body 11, so that the water purification pipe body 40 can move slightly in the circumferential direction in the through groove 14 to adjust the deviation caused by the size and ensure that the water purification connector 41 is facing the water purification outlet channel.

[0057] In this embodiment, the positioning portion is located above the lateral window 12 .

[0058] In this embodiment, the first limiting guide portion includes a first guide surface 15 extending along the length direction of the shell body 11 and a first axial limiting surface 16 for axially limiting the body core 20 .

[0059] In this embodiment, the first guide surface 15 is connected to the first axial limiting surface 16 and the first guide surface 15 is located below the first axial limiting surface 16 .

[0060] In this embodiment, the first limiting guide portion further includes a first circumferential limiting surface 17 .

[0061] like Figure 6 As shown, the first limiting guide part is plate-shaped, and the side facing the middle of the shell body 11 is provided with the first guide surface 15 and the first axial limiting surface 16, and the side facing the lateral window 12 is the first circumferential limiting surface 17. In this embodiment, the first limiting guide part is provided with two and arranged oppositely and located on the left and right sides of the lateral window respectively. The first axial limiting surface 16 is arc-shaped, the first guide surface 15 is parallel to the central axis of the shell body 11, and the first circumferential limiting surface 17 is parallel to the longitudinal section of the lateral window 12.

[0062] The body core 20 is provided with a clean water outlet channel 21 and a second limiting guide part, which is located in the shell body 11. The clean water pipe extends into the shell body 11 from the top of the shell body 11 and is positioned in the shell body 11 and at the corresponding lateral window 12 by the positioning function of the positioning part. The body core 20 extends into the shell body 11 from the bottom of the shell body 11 and under the guidance and limiting cooperation of the first limiting guide part and the second limiting guide part, the side of the body core 20 faces the lateral window 12. The locking piece 30 extends from the lateral window 12 and fixes the body core 20 and the shell relatively; and during the guiding and limiting cooperation between the first limiting guide part and the second limiting guide part, the clean water pipe faces and is inserted into the clean water outlet channel 21.

[0063] In this embodiment, the second limiting guide portion includes a second guide surface 22 that can slide with the first guide surface 15 and a second axial limiting surface 23 that can limit with the first axial limiting surface 16. During the upward movement of the main body core 20, it is first guided by the sliding cooperation between the first guide surface 15 and the second guide surface 22, and then the axial limiting cooperation between the first axial limiting surface 16 and the second axial limiting surface 23 is used to limit the continued upward movement of the main body core 20.

[0064] In this embodiment, the second guide surface 22 is connected to the second axial limiting surface 23 and the second guide surface 22 is located below the second axial limiting surface 23 .

[0065] In this embodiment, the second limiting guide portion further includes a second circumferential limiting surface 24, which can cooperate with the first circumferential limiting surface 17 to limit the circumferential movement of the body core 20. Figure 7 and Figure 8 As shown, the second axial limit surface 23 is located at the top end of the body core 20 and is an arc surface. The second guide surface 22 is parallel to the central axis of the body core 20 and extends vertically downward. The second circumferential limit surface 24 protrudes from the second axial limit surface 23 and the second guide surface 22 and is connected to the second axial limit surface 23 and the second guide surface 22.

[0066] In this embodiment, during the sliding cooperation between the first guide surface 15 and the second guide surface 22, the clean water connector 41 and the clean water outlet channel 21 are plugged in and cooperated; when the clean water connector 41 and the clean water outlet channel 21 are plugged in and cooperated, the first axial limit surface 16 and the second axial limit surface 23 are exactly fitted together for axial limit, and at this time, the side surface of the body core 20 is directly opposite to the lateral window 12. Figure 7 As shown, a mounting plate 25 is provided on the side of the body core 20. When the central axis of the mounting plate 25 coincides with the central axis of the lateral window 12, the side of the body core 20 and the lateral window 12 are directly opposite to each other.

[0067] In this embodiment, the locking element 30 is a collar. After the collar extends into the housing from the lateral window 12 , its bottom end is pressed against the side surface of the body core 20 and is fixedly connected to the lateral window 12 .

[0068] In this embodiment, a step surface 26 is provided on the side of the main body core 20, and the bottom end of the ring is pressed against the step surface 26; the outer periphery of the ring is provided with an external thread, and the lateral window 12 is provided with an internal thread, and the ring and the lateral window 12 are fixed by screwing the internal and external threads.

[0069] In this embodiment, the mounting structure further includes a strength reinforcement member 50, which is fixed to the body core 20, and the outer side of the strength reinforcement member 50 forms the step surface 26. In this embodiment, the strength reinforcement member 50 is made of metal. Figure 5 As shown, the strength reinforcement member 50 is fixedly connected to the inner side of the mounting plate 25 and extends out of the mounting plate 25 , and the extended portion forms the step surface 26 .

[0070] In this embodiment, the installation structure further includes an elbow 60, a bushing 70, a tap water outlet hose 80 and an extraction head 90. The head end of the elbow 60 is connected to the shell body 11. The bushing 70 is fixed to the end of the elbow 60 and a plug hole 71 is provided on the outside of the bushing 70. The end of the clean water pipe body 40 is inserted into the plug hole 71. The body core 20 is provided with a mixed water outlet channel 27. One end of the tap water outlet hose 80 is connected to the mixed water outlet channel 27, and the other end passes through the bushing 70 and is connected to the extraction head 90.

[0071] In this embodiment, Fig.11 As shown, the clean water pipe body 40 is against the outer arc surface of the inner circumference of the curved pipe 60, and the tap water outlet hose 80 is against the inner arc surface of the inner circumference of the curved pipe 60, so that the clean water pipe body 40 and the tap water outlet hose 80 are independent of each other and do not affect or interfere with each other, thereby ensuring that the tap water outlet hose 80 can be pulled out freely.

[0072] In this embodiment, the main body core 20 is further provided with a guide rib 28 for guiding the insertion of the tap water outlet hose 80 when it is repaired or replaced, and the guide rib 28 has a guide slope. Figure 8 As shown, the guide ribs 28 are triangular in structure and are provided with a plurality of them. When the tap water outlet hose 80 needs to be repaired or replaced, the new tap water outlet hose 80 needs to be extended from the bushing 70 into the elbow 60, and the guide slope can guide the tap water outlet hose 80 at this time.

[0073] In this embodiment, the installation structure also includes a control valve core 100, which is installed in the side window 12 and cooperates with the body core 20. In this embodiment, the control valve core 100 can control the opening or closing, flow rate, and temperature adjustment of the tap water outlet hose 80, and can also control the opening or closing and flow rate adjustment of the purified water outlet pipe. The specific structure of the control valve core can refer to the utility model patent with the authorization announcement number CN209414686U and the patent name of a dual-waterway faucet valve core, which will not be repeated here.

[0074] The installation process of the water purification pipe is as follows:

[0075] First, the water purification pipe body 40 and the water purification connector 41 are connected and fixed, and then the water purification connector 41 is extended from the top of the shell body 11 into the shell body 11; then, the water purification pipe body 40 is squeezed into the through groove 14 through its own elastic deformation from the lateral opening of the through groove 14 and the water purification connector 41 is against the bottom of the through groove 14, as shown in FIG. Figure 1 As shown, since the size of the water purification connector 41 is larger than the size of the through groove 14, the water purification connector 41 always rests against the bottom end of the through groove 14, and since the spacing of the lateral openings of the through groove 14 is less than or equal to the diameter of the water purification pipe body 40, the water purification pipe body 40 will not fall out of the lateral opening, which can ensure the stable positioning of the water purification pipe. At this time, the water purification connector 41 can be observed from the lateral window 12, as shown in FIG. Figure 3 As shown;

[0076] Then, if Figure 2 As shown, the body core 20 is extended into the shell body 11 from the bottom end of the shell body 11;

[0077] like Figure 4 As shown, when the first guide surface 15 just starts to slide with the second guide surface 22, the clean water connector 41 just contacts with the clean water outlet channel 21, and the plugging process of the clean water connector 41 and the clean water outlet channel 21 can be observed from the side window 12; when the second guide surface 22 continues to slide along the first guide surface 15, the clean water connector 41 is inserted into the clean water outlet channel 21, and when the second axial limit surface 23 abuts against the first axial limit surface 16, the clean water connector 41 is just plugged with the clean water outlet channel 21, and the mounting plate 25 is just opposite to the side window 12;

[0078] Then, the collar is inserted from the side window 12, and the locking piece 30 is continuously inserted into the side window 12 through the threaded connection of the internal and external threads until the bottom end of the collar is pressed against the step surface 26 of the strength reinforcement piece 50, thus completing the installation of the water purification pipe and the body core 20.

[0079] If the water purification connector 41 and the water purification outlet channel 21 deviate due to size problems during the plugging process, the position of the water purification pipe body 40 in the groove 14 can be slightly adjusted so that the two can be aligned to ensure smooth plugging. Since the plugging process of the water purification pipe and the water purification outlet channel 21 can be directly seen from the side window 12 (visual installation), it provides great convenience for the installation of the water purification pipe and avoids the time cost caused by blind installation.

[0080] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
