[0005] The side wall of the first valve core seat is provided with at least a hot water passage hole and a cold water passage hole, and the side wall of the second valve core seat is provided with at least two first water outlet passage holes. The side walls of the first valve core seat and the second valve core seat are each provided with a plurality of first abutment surfaces. The hot water passage hole, the cold water passage hole and each first water outlet passage hole are located on a corresponding first abutment surface.

[0006] The side wall of the pre-embedded box is provided with a clearance through hole corresponding to each first abutment surface. Each clearance through hole is equipped with a universal water inlet and outlet connector. The universal water inlet and outlet connector has a first limiting part located inside the pre-embedded box and a connecting part extending outside the pre-embedded box. A second abutment surface is formed on the first limiting part that is in sealing contact with the first abutment surface.

[0007] Furthermore, the connecting structure is a connecting pipe connecting the first valve core seat and the second valve core seat, and the first valve core seat, the second valve core seat and the connecting pipe are integrally formed.

[0008] Furthermore, the side wall of the first valve core seat is provided with at least one second water outlet hole, and the side wall of the second valve core seat is provided with a water inlet hole. Each second water outlet hole and water inlet hole is located on a corresponding first abutment surface. A partition is provided between the first valve core seat and the second valve core seat in the pre-embedded box, and a through hole is provided through the partition.

[0009] The connecting structure is a valve core seat connecting joint that passes through the connecting hole, and one end of the valve core seat connecting joint forms a third abutment surface that is in sealing contact with the first abutment surface corresponding to the second water outlet hole of the first valve core seat, and one end of the valve core seat connecting joint forms a fourth abutment surface that is in sealing contact with the first abutment surface corresponding to the water inlet hole of the second valve core seat.

[0010] Furthermore, the valve core seat connecting joint has a second limiting portion located on one side of the partition and a connecting portion extending to the other side of the partition.

[0011] Furthermore, the third abutment surface is an inclined surface that gradually approaches the first valve core seat from top to bottom, the fourth abutment surface is an inclined surface that gradually approaches the second valve core seat from top to bottom, and the first abutment surface is an inclined surface that matches the third abutment surface or the fourth abutment surface.

[0012] Furthermore, finite blocks are formed at the lower ends of the second, third, and fourth abutment surfaces.

[0013] Furthermore, each of the first abutment surfaces is provided with a sealing groove, and a sealing ring is provided inside the sealing groove.

[0014] Furthermore, the second abutment surface is an inclined surface that gradually approaches the first valve core seat or the second valve core seat from top to bottom, and the first abutment surface is an inclined surface that matches the second abutment surface.

[0015] Furthermore, several connecting pieces are integrally formed on both the first valve core seat and the second valve core seat, and each connecting piece is locked to the pre-embedded box body by a locking component.

[0016] Furthermore, it also includes a mixing valve core installed on the first valve core seat and a water distribution valve core installed on the second valve core seat.

[0017] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: The multi-outlet concealed faucet is designed with a universal inlet / outlet connector, and a first abutting surface is formed on the sidewalls of the first and second valve core seats, while a second abutting surface is formed on the first limiting portion of the universal inlet / outlet connector. This allows for a simple assembly process and improved assembly efficiency, as the first and second valve core seats and the universal inlet / outlet connector can be sealed and connected through the abutting and sealing contact between the first and second abutting surfaces during actual use. Furthermore, the pre-embedded housing, the first valve core seat, the second valve core seat, and the universal inlet / outlet connector all have relatively simple structures, resulting in fewer components used in the entire multi-outlet concealed faucet. This facilitates manufacturing, reduces overall costs, and allows for flexible production based on actual customer needs during manufacturing. [Attached Image Description]

[0043] Please see Figures 1 to 11 As shown, this utility model discloses a multi-outlet concealed faucet 100 that can be flexibly manufactured. The multi-outlet concealed faucet 100 includes a pre-embedded box 1, a first valve core seat 2 that can be detachably installed in the pre-embedded box 1, a second valve core seat 3 that can be detachably installed in the pre-embedded box 1, and a universal inlet and outlet connector 4. The first valve core seat 2 and the second valve core seat 3 are connected by a connecting structure, so that water can enter from the first valve core seat 2 to the second valve core seat 3.

[0044] The side wall of the first valve core seat 2 is provided with at least a hot water passage hole 21 and a cold water passage hole 22. The hot water passage hole 21 is used to allow the incoming hot water to pass through, and the cold water passage hole 22 is used to allow the incoming cold water to pass through. The side wall of the second valve core seat 3 is provided with at least two first water outlet passage holes 31. Each first water outlet passage hole 31 is used to realize the multi-way output of mixed water. The side walls of the first valve core seat 2 and the second valve core seat 3 are each formed with a plurality of first abutment surfaces 5. The hot water passage hole 21, the cold water passage hole 22 and each first water outlet passage hole 31 are located on a corresponding first abutment surface 5.

[0045] The side wall of the pre-embedded box 1 is provided with a clearance through hole 11 corresponding to each first abutment surface 5. Each clearance through hole 11 is equipped with a universal water inlet / outlet connector 4. The universal water inlet / outlet connector 4 has a first limiting part 41 located inside the pre-embedded box 1 and a connecting part 42 extending outside the pre-embedded box 1. The first limiting part 41 is used to limit the universal water inlet / outlet connector 4 so that the universal water inlet / outlet connector 4 will not leave the pre-embedded box 1. The connecting part 42 is used to connect with a pipe (not shown) inside the wall. A second abutment surface 411 is formed on the first limiting part 41 to seal and contact the first abutment surface 5.

[0046] This utility model designs a multi-outlet concealed faucet 100 including a universal inlet / outlet connector 4, with a first abutment surface 5 formed on the sidewalls of the first valve core seat 2 and the second valve core seat 3, and a second abutment surface 411 formed on the first limiting part 41 of the universal inlet / outlet connector 4. This allows for seamless connection between the first valve core seat 2 and the second valve core seat 3 and the universal inlet / outlet connector 4 through the abutment and sealing contact of the first abutment surface 5 and the second abutment surface 411 during actual use. The assembly process is very simple and can improve assembly efficiency. Simultaneously, the pre-embedded housing 1, the first valve core seat 2, the second valve core seat 3, and the universal inlet / outlet connector 4 are all... The structure of the faucet is relatively simple, and the number of parts used in the entire multi-outlet concealed faucet 100 is also relatively small, which makes it easy to manufacture and reduces the overall cost. In the specific production process, it can be flexibly produced according to the actual needs of customers. For example, if the customer only needs the universal inlet and outlet connector 4, only the universal inlet and outlet connector 4 can be produced; if the customer only needs the valve core seat, only the valve core seat can be produced; if the customer only needs the pre-embedded box 1, only the pre-embedded box 1 can be produced. For customers, they only need to purchase the corresponding parts according to their actual needs, instead of purchasing the entire multi-outlet concealed faucet.

[0047] As the first specific embodiment of this utility model, please refer to the following: Figures 9-11 As shown, the connecting structure is a connecting pipe 61 connecting the first valve core seat 2 and the second valve core seat 3. Specifically, the connecting pipe 61 connects the water outlet end of the first valve core seat 2 and the water inlet end of the second valve core seat 3, and the first valve core seat 2, the second valve core seat 3 and the connecting pipe 61 are integrally formed.

[0048] In a first specific embodiment of this utility model, a second water outlet hole 23 may be provided on the side wall of the first valve core seat 2, and the second water outlet hole 23 is located on a first abutment surface 5 corresponding to the first valve core seat 2. This allows mixed water to be transported to the second valve core seat 3 through a connecting structure, and water can also be discharged using the second water outlet hole 23 of the first valve core seat 2. Simultaneously, the side walls of both the first valve core seat 2 and the second valve core seat 3 have three first abutment surfaces 5, and the angle between the middle first abutment surface 5 and the other two first abutment surfaces 5 is 90° for both the first valve core seat 2 and the second valve core seat 3. The embedded box 1 is a square box, and clearance through holes 11 are correspondingly provided on the four side walls of the embedded box 1 to facilitate the installation of universal inlet and outlet connectors 4 on the four side walls of the embedded box 1.

[0049] In a first specific embodiment of the present invention, a limiting block 7 is formed at the lower end of the second abutment surface 411. The limiting block 7 is used to limit the assembly of the first valve core seat 2 and the second valve core seat 3.

[0050] In the first specific embodiment of this utility model, the multi-outlet concealed faucet 100 can be pre-embedded in the wall of the pre-embedded box 1. At the same time, the connecting parts 42 of each universal inlet and outlet connector 4 pass through the clearance hole 11 from the pre-embedded box 1 and are pre-connected to the pipe in the wall. When installing the first valve core seat 2 and the second valve core seat 3, the first valve core seat 2, the second valve core seat 3 and the connecting pipe 61 need to be installed into the pre-embedded box 1 from the outside to the inside. During the installation process, each first abutting surface 5 on the first valve core seat 2 and the second valve core seat 3 will push the corresponding universal inlet and outlet connector 4 outward. Since the universal inlet and outlet connector 4 has a first limiting part 41 located inside the pre-embedded box 1, after the first valve core seat 2, the second valve core seat 3 and the connecting pipe 61 are installed in place, each first abutting surface 5 can abut and seal with the second abutting surface 411 of the corresponding universal inlet and outlet connector 4.

[0051] In the first specific embodiment of this utility model, by integrally molding the first valve core seat 2, the second valve core seat 3 and the connecting pipe 61, it is easier to perform assembly operations, and only one set of molds needs to be developed during manufacturing. However, it is not very convenient to expand in actual use.

[0052] As a second specific embodiment of this utility model, please refer to the following: Figures 2 to 5 as well as Figure 7 , Figure 8 As shown, the side wall of the first valve core seat 2 is also provided with at least one second water outlet hole 23, which is used to output mixed water or transport mixed water to the second valve core seat 3; the side wall of the second valve core seat 3 is also provided with a water inlet hole 32, which is used to input mixed water into the second valve core seat 3. Each second water outlet hole 23 and water inlet hole 32 is located on a corresponding first abutment surface 5; a partition 12 is provided between the first valve core seat 2 and the second valve core seat 3 in the pre-embedded box 1, that is, the partition 12 is used to separate the first valve core seat 2 and the second valve core seat 3, and a through hole 121 is provided through the partition 12;

[0053] The connecting structure is a valve core seat connecting joint 62 passing through the connecting through hole 121, and one end of the valve core seat connecting joint 62 forms a third abutting surface 621 that is in sealing contact with the first abutting surface 5 corresponding to the second water outlet hole 23 of the first valve core seat 2, and one end of the valve core seat connecting joint 62 forms a fourth abutting surface 622 that is in sealing contact with the first abutting surface 5 corresponding to the water inlet hole 32 of the second valve core seat 3.

[0054] In the first specific embodiment of this utility model, the multi-outlet concealed faucet 100 can be pre-embedded in the wall with the pre-embedded box 1, and the connecting part 42 of each water inlet and outlet universal connector 4 can pass through the clearance hole 11 from the pre-embedded box 1 and be pre-connected to the pipe in the wall. Before installing the first valve core seat 2 and the second valve core seat 3, the valve core seat connecting connector 62 needs to pass through the connecting hole 121 from one side of the partition plate 12. When installing the first valve core seat 2 and the second valve core seat 3, the first valve core seat 2 and the second valve core seat 3 need to be installed into the pre-embedded box 1 from the outside to the inside. During the installation of the first valve core seat 2 and the second valve core seat 3, each first abutting surface 5 on the first valve core seat 2 and the second valve core seat 3 will push the corresponding inlet and outlet universal connector 4 outward. Since the inlet and outlet universal connector 4 has a first limiting part 41 located inside the pre-embedded box 1, after the first valve core seat 2 and the second valve core seat 3 are installed in place, each first abutting surface 5 can abut and seal with the second abutting surface 411 of the corresponding inlet and outlet universal connector 4. At the same time, the two opposing first abutting surfaces 5 of the first valve core seat 2 and the second valve core seat 3 will abut and seal with the third abutting surface 621 and the fourth abutting surface 622, respectively.

[0055] In the second embodiment of this utility model, since the first valve core seat 2 and the second valve core seat 3 are connected by a valve core seat connecting joint 62, in the specific assembly process, the valve core seat connecting joint 62 needs to be installed into the connecting hole 121 of the partition plate 12 before the first valve core seat 2 and the second valve core seat 3 can be installed. Therefore, compared with the first embodiment, the assembly efficiency will be reduced, and a set of molds for the valve core seat connecting joint 62 also needs to be developed. However, in the specific use, it can be easily expanded according to actual needs. For example, more installation positions can be added to the pre-embedded box 1 to install more valve core seats.

[0056] In a second specific embodiment of this utility model, the sidewalls of the first valve core seat 2 and the second valve core seat 3 are each formed with four first abutment surfaces 5, and the included angle between any two adjacent first abutment surfaces 5 is 90°, regardless of whether it is the first valve core seat 2 or the second valve core seat 3. The pre-embedded box 1 is a square box, and each of the four sidewalls of the pre-embedded box 1 is provided with corresponding clearance through holes 11, so as to facilitate the installation of universal water inlet and outlet connectors 4 on the four sidewalls of the pre-embedded box 1.

[0057] In a second specific embodiment of the present invention, the valve core seat connecting joint 6 has a second limiting part 63 located on one side of the partition 12 and a connecting part 64 extending to the other side of the partition 12. When the first valve core seat 2 and the second valve core seat 3 press against the valve core seat connecting joint 6 from both ends, the second limiting part 63 can also press against the partition 12 to ensure stability in use.

[0058] In a second specific embodiment of this utility model, the third abutment surface 621 is an inclined surface that gradually approaches the first valve core seat 2 from top to bottom, and the fourth abutment surface 622 is an inclined surface that gradually approaches the second valve core seat 3 from top to bottom. The first abutment surface 5 is an inclined surface that matches the third abutment surface 621 or the fourth abutment surface 622. By adopting the above inclined surface structure design, it is not only convenient to assemble the first valve core seat 2 and the second valve core seat 3, but also to ensure the stability and sealing performance after assembly.

[0059] In a second specific embodiment of this utility model, a limiting block 7 is formed at the lower end of the second abutment surface 411, the third abutment surface 621 and the fourth abutment surface 622. The limiting block 7 is used to limit the assembly of the first valve core seat 2 and the second valve core seat 3.

[0060] In this invention, each of the first abutting surfaces 5 is provided with a sealing groove 51, and a sealing ring 52 is provided in the sealing groove 51, which can achieve a better sealing effect.

[0061] In this invention, the second abutment surface 411 is an inclined surface that gradually approaches the first valve core seat 2 or the second valve core seat 3 from top to bottom, and the first abutment surface 5 is an inclined surface that matches the second abutment surface 411. By adopting the above inclined surface structure design, it is possible to facilitate the assembly operation of the first valve core seat 2 and the second valve core seat 3, and to ensure the stability and sealing performance after assembly.

[0062] In this invention, several connecting pieces 8 are integrally formed on both the first valve core seat 2 and the second valve core seat 3. Each connecting piece 8 is locked to the pre-embedded housing 1 by a locking member 81, wherein the locking member 81 can be a bolt or a screw. By forming multiple connecting pieces 8 on both the first valve core seat 2 and the second valve core seat 3, and using the locking member 81 to lock the connecting pieces 8 to the pre-embedded housing 1, the stability of the first valve core seat 2 and the second valve core seat 3 after assembly can be ensured, preventing the first valve core seat 2 and the second valve core seat 3 from loosening during use.

[0063] In this utility model, please refer to the following: Figure 1 and Figure 2As shown, the multi-outlet concealed faucet 100 also includes a mixing valve core 91 installed on the first valve core seat 2 and a water distribution valve core 92 installed on the second valve core seat 3. Both the mixing valve core 91 and the water distribution valve core 92 are common components of faucets, and their specific structures and working principles are well known to those skilled in the art; therefore, they will not be described in detail here. During operation, the hot water supplied by the hot water passage 21 and the cold water supplied by the cold water passage 22 of the first valve core seat 2 are mixed inside the mixing valve core 91. The mixed water is then transported to the water distribution valve core 92 of the second valve core seat 3 through a connecting structure. The water distribution valve core 92 controls the first outlet passage 31 of the second valve core seat 3 to output the mixed water. Simultaneously, when the first valve core seat 2 is provided with other second outlet passages 23 besides the connecting structure, the mixed water can also be output through these second outlet passages 23.

[0064] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
