[0027] Example

[0028] Combination Figures 1 to 7 As shown, this embodiment provides a shower faucet, including a housing 1 and an integrally formed inner core 2; the housing has a first mounting cavity 3 with an opening on one end face, a second mounting cavity 4 with a front opening communicating with the first mounting cavity 3 and located on the opening side, for mounting a temperature regulating valve core 5, and a third mounting cavity 6 with a lower opening on the other side, for connecting a lower water outlet device; a communication port 7 is provided between the first mounting cavity 3 and the third mounting cavity 6;

[0029] The inner core 2 is installed in the first mounting cavity 3, which includes a seat part 8 disposed opposite to the second mounting cavity 4. The seat part 8 is provided with a first water inlet cavity 9 with a back opening communicating with the first water inlet hole 10; a water inlet channel 12 with one end communicating with the second water inlet hole 11 of the seat part 8, and a second water inlet cavity 13 with a back opening on the water inlet channel 12; a water outlet cavity 14 with an upper opening in the middle for connecting to the upper water outlet device, which is equipped with a first switching valve 15; a first water outlet channel 17 communicating with the water outlet cavity 14 and the mixing water outlet hole 16 of the seat part 8; a second water outlet channel 18 with one end communicating with the water outlet cavity 14 and the other end sealed and inserted into the connecting port 7; and an opening 20 on the outer shell 1 that is adapted to the first water inlet cavity 9, the second water inlet cavity 13 and the water outlet cavity 14.

[0030] In this embodiment, as Figures 5 to 7 As shown, the one-piece molded inner core 2 is formed in one go through a mold. This allows for the integration of complex internal water channels into a single component. Specifically, the front opening connection structure between the first mounting cavity 3 and the second mounting cavity 4 can be achieved through a straight or stepped channel to ensure a smooth transition of the water flow path. Furthermore, the design of the connecting port 7 can be cylindrical, conical, or other adaptable shapes to achieve a sealed connection of the second water outlet channel 18, thereby avoiding the use of additional connectors. In a preferred embodiment, the first water inlet cavity 9, with an opening on the back of the seat 8, facilitates demolding during core pulling; threads can be provided within the first water inlet cavity 9 for connecting the water inlet connector.

[0031] In this embodiment, the other end of the water inlet channel 12 is open to facilitate core extraction from the open end. The opening is then sealed with a first plug (not shown in the attached figure) to form an internal water passage. The back opening of the second water inlet cavity 13 facilitates demolding during core extraction; it can also be threaded for connecting a water inlet connector. The upper opening of the water outlet cavity 14 can be adapted to the upper water outlet device via threaded connection, snap-fit ​​connection, or flange connection. The inclination angle of the first water outlet channel 17 can be adjusted according to actual needs so that the first water outlet channel 17 can communicate with the inner cavity of the water outlet cavity 14 and the mixing water outlet hole 16 of the seat part 8. Simultaneously, the first water outlet channel 17 is also open on one side of the mixing water outlet hole 16 to facilitate core extraction from the open end, followed by sealing with a second plug (not shown in the attached figure) to form an internal water passage.

[0032] In this embodiment, the other end of the second water outlet channel 18 is also open, and a plurality of sealing grooves 19 are provided on its outer peripheral wall for fitting a sealing ring; after the inner core 2 is assembled into the first mounting cavity 3 from the opening on one side of the outer shell, the other end of the second water outlet channel 18 is sealed and inserted into the connecting port 7, thereby connecting to the third mounting cavity 6.

[0033] This application utilizes a one-piece molded inner core 2 design to integrate the complex internal water channels of a shower faucet into a single component, fundamentally solving the problems of increased mold costs and assembly steps caused by traditional component molding. Specifically, by optimizing the opening positions of each mounting cavity, the channel routing, and the opening settings of one end of the water inlet channel 12 and the first water outlet channel 17, and through the coordinated design of plug sealing methods, the complex water channels can be directly molded in a single inner core 2, significantly reducing manufacturing complexity. Furthermore, this design avoids the risk of leakage at component interfaces, while improving the reliability of water channel connections and assembly efficiency.

[0034] like Figures 2 to 4 As shown, the outer casing 1 is provided with a first mounting cavity 3, a second mounting cavity 4, and a third mounting cavity 6. The first mounting cavity 3 is used to accommodate the inner core 2. The second mounting cavity 4 is connected to the first mounting cavity 3 through a front opening and is used to install a temperature regulating valve core 5 to adjust the water temperature and flow rate. The water outlet cavity 14 in the middle is connected to the first water outlet channel 17 and the second water outlet channel 18. The water outlet cavity 14 is used to install a first switching valve 15 to control the distribution of water flow, i.e., switching between water outlet from the upper water outlet device or water outlet from the second water outlet channel 18. The third mounting cavity 6 is connected to the lower water outlet device through a lower opening.

[0035] Specifically, in this embodiment, such as Figure 5 and Figure 6 As shown, the inner core 2, as the core component, has a seat 8 opposite to the second mounting cavity 4, and forms a first water inlet 10, a second water inlet 11, and a mixing outlet 16. The first water inlet cavity 9, with an opening on the back of the seat 8, connects to the first water inlet 10, allowing cold or hot water to be introduced via a water inlet connector. One end of the water inlet channel 12 connects to the second water inlet 11 of the seat 8, and the other end has a second water inlet cavity 13 with an opening on the back, allowing hot or cold water to be introduced via a water inlet connector. The front of the seat 8 forms a mounting surface 22 for end-face sealing with the temperature control valve core 5.

[0036] Since the water channels are all located on the inner core 2, the outer shell 1 forms a uniformly distributed thin-walled structure. In order to better and more stably install the temperature control valve core 5, an inner sleeve 21 of the central cavity is provided in the second mounting cavity 4. One end of the inner sleeve 21 is provided with an internal thread and screwed onto the seat part 8, and the other end is also provided with an internal thread for screwing onto the sleeve, so as to fix and limit the temperature control valve core 5 installed in the central cavity.

[0037] like Figure 2As shown, this application further proposes an end cap 23, which is detachably connected to the end face opening of the first mounting cavity 3; the shape of the end cap 23 is adapted to the shape of the end face opening of the first mounting cavity 3. A thickened portion 24 is provided on the inner sidewall of the first mounting cavity 3, and a first through hole 25 is provided on the thickened portion 24; a second through hole is provided on the end cap 23, which is fixed by screws, thereby limiting the inner core 2. At the same time, the end cap 23 can block the end face opening of the first mounting cavity 3, which serves an aesthetic purpose.

[0038] This application also includes a switching handle 26 connected to a first switching valve 15 on the water outlet chamber 14, used to rotate the core of the first switching valve 15 to switch the water path. A second switching valve 27 is installed in the third mounting chamber 6; the lower water outlet device is a water outlet support arm 28, which has a support arm water outlet channel and a lower water outlet channel; the rotation of the water outlet support arm 28 can control the second switching valve 27 to switch between the support arm water outlet channel and the lower water outlet channel. A placement area 29 is provided on the outer casing 1 so that after the water outlet support arm 28 is rotated to switch to the lower water outlet, the water outlet support arm 28 can be placed within the placement area 29; this avoids the water outlet support arm 28 protruding outwards and occupying shower space, and also serves as a reminder that when the water outlet support arm 28 is placed within the placement area 29, the support arm water outlet channel is closed and the lower water outlet channel is open.
