The second direction is Figure 4 In the up and down direction. In this embodiment, the second water flow section 12 and the third water flow section 13 both extend upward from the first water flow section 11, so that the thermostatic valve and the switching valve are located on the same side later, which is convenient for user operation. The water flow member 1 is also provided with a water flow channel 14, which passes through the first water flow section 11, the second water flow section 12 and the third water flow section 13. The water flow channel 14 opens at the end surfaces of the second water flow section 12 and the third water flow section 13 away from the first water flow section 11, respectively. In this embodiment, both openings of the water flow channel 14 face upward.

The first insert 2 and the second insert 3 can also be formed by secondary injection molding, such as Figure 6 , Figure 7 , making the preparation simpler.

[0059] refer to Figure 5 The filling member 4 is injection molded on the water passing member 1, the first insert 2 and the second insert 3, and the filling member 4 covers the outer wall of the water passing member 1 and fills at least the second space 5, the first space 6, the third space 7 and the fourth space 8. The filling member 4 covers the outer wall of the water passing member 1 so that the openings at both ends of the water passing channel 14 are exposed so that the water passing channel 4 will not be blocked by the filling member 4, and the water passing channel 4 can realize the function of passing water. The purpose of covering is to prevent water from overflowing from the outer wall of the water passing member 1 when overflowing.

[0060] refer to Figure 2 The filling member 4 is provided with a first valve core installation portion 41 , a water inlet 42 , a second valve core installation portion 43 , and a water outlet 44 .

[0061] The first valve core mounting portion 41 is used for mounting a thermostatic valve. The top surface of the first valve core mounting portion 41 is higher than the top surface of the first insert 2. The first valve core mounting portion 41 fills part of the first hole 21 and is provided with a first valve core water inlet hole 411 and a first valve core water outlet hole 412 extending along the second direction. There are two first valve core water inlet holes 411, and the first valve core water outlet hole 412 is connected to one end of the water passage 14.

[0062] The water inlet channel 42 extends in a direction perpendicular to the second direction and is connected to the first valve core water inlet hole 411. In this embodiment, there are two water inlet channels 42 and they correspond one to one to the first valve core water inlet holes 411. The two water inlet channels 42 are respectively suitable for cold water and hot water. In this embodiment, both water inlet channels 42 extend in a third direction perpendicular to the first direction and the second direction.

[0063] The second valve core installation part 43 is used to install the switching valve. The top surface of the second valve core installation part 43 is higher than the top surface of the second insert 3. The second valve core installation part 43 fills part of the second hole 31 and is provided with a second valve core water inlet hole 431 and a second valve core water outlet hole 432 extending along the second direction. The second valve core water inlet hole 431 is connected to the other end of the water passage 14. The number of the second valve core water outlet holes 432 is at least two.

[0064] The water outlet 44 extends in a direction perpendicular to the second direction and is connected to the second valve core water outlet hole 432. The water outlet 44 is connected to the second valve core water outlet hole 432 in a one-to-one correspondence.

[0065] The first insert 2 and the second insert 3 are provided with a first surface 24 and a second surface 25 which are opposite to each other and perpendicular to the second direction. The filler 4 is also provided with an anti-slip portion 45 which covers the first surface 24 and the second surface 25 to prevent the first insert 2 and the second insert 3 from escaping from the filler 4 along the second direction.

[0066] During processing, the first insert 2 and the second insert 3 are first assembled in the mold. The assembly method can be to screw the threaded sections 22 on the first insert 2 and the second insert 3 with the corresponding structure on the mold. Then, the water passage 14 of the water passage 1 is inserted into the plug-in column on the mold to achieve positioning, such as Figure 4 Then the injection molding machine is turned on to form the filling piece 4.

[0067] In the prior art, reference Figure 8 The water outlet core includes a water flow part 1, a first insert 2 and a filling part 4. The first insert 2 is used to connect with external parts. The first insert 2 and the water flow part 1 are connected to each other. The first insert 2 has a first hole 21. Then the filling part 4 is injection molded on the water flow part 1 and the first insert 2 to form an outer shell and / or other water channels, such as forming a water channel connected to the water channel of the water flow part 1 in the first hole 21; however, when the injection molding process is not good, or because of long-term use, a gap is generated between the outer wall of the water flow part 1 and the filling part 4, water will flow along the gap from the wall surface of the first hole 21 of the first insert 2 or the outer wall of the first insert 2 to the outside of the water outlet core (such as the weight mark route), causing overflow problems.

[0068] As for the water outlet inner core formed by the method of this embodiment, due to the existence of the second space 5, the first space 6, the third space 7 and the fourth space 8, the first insert 2, the second insert 3 and the water flow part 1 do not contact each other. When the filling piece 4 is injection molded, the filling piece 4 fills the second space 5, the first space 6, the third space 7 and the fourth space 8 to connect the first insert 2, the second insert 3 and the water flow part 1. Even if a gap is generated between the outer wall of the water flow part 1 and the filling piece 4 due to poor injection molding process or long-term use, since the filling piece 4 separates the first insert 2, the second insert 3 from the water flow part 1, the water flowing out of the first valve core water outlet hole 412 will only reach the second valve core water inlet hole 431 along the outer wall of the water flow part 1, and will not overflow to the outside of the water outlet inner core through the wall surface of the first hole 21 of the first insert 2 or the outer wall of the first insert 2, and the water path is consistent with normal times.

[0069] Compared with the prior art, this embodiment has the following beneficial effects:

Due to the existence of the first space 6, the first insert 2 and the water flow part 1 do not contact each other. When the filling part 4 is injection molded, the filling part 4 fills the first space 6 to connect the first insert 2 and the water flow part 1. Even if a gap is generated between the outer wall of the water flow part 1 and the filling part 4 due to poor injection molding process or long-term use, the water overflowing from the water inlet end of the water flow channel 14 will only reach the water outlet end of the water flow channel 14 along the outer wall of the water flow part 1, and will not overflow to the outside of the water outlet core, thereby increasing product life and processing yield.

[0071] In this embodiment, the water-passing member 1 also includes a second water-passing portion 12 extending along the second direction, the second water-passing portion 12 is connected to the first water-passing portion 11, the water-passing channel 14 passes through the second water-passing portion 12, the first hole 21 is suitable for the second water-passing portion 12 to extend into, and there is a second space 5 between the hole wall of the first hole 21 and the second water-passing portion 12; the filling member 4 also fills the second space 5. Due to the existence of the second space 5, the water-passing member 1 is still not in contact with the second insert 3, and the filling member 4 fills the first space 6 and the second space 5 to connect the first insert 2 and the water-passing member 1, and there will be no overflow problem. The provision of the second water-passing portion 12 can reduce the length of the plug-in column on the mold that is plugged into the water-passing channel 14, thereby making the product processing simpler and less prone to damage, and reducing the demolding force when forming the waterway on the plug-in column.

[0072] In this embodiment, the filling member 4 is provided with a first valve core mounting portion 41 for mounting the valve core, the first valve core mounting portion 41 fills the first hole 21, and is provided with a first valve core water inlet hole 411 and a first valve core water outlet hole 412 extending along the second direction, the first valve core water outlet hole 412 is connected to the water passage 14, thereby completing the water path connected to the water inlet end and the water outlet end of the valve core.

[0073] In this embodiment, the filling member 4 is also provided with a water inlet 42, which extends in a direction perpendicular to the second direction and is connected to the first valve core water inlet hole 411, thereby completing the water inlet channel. The second direction is the direction of installing the valve core. If the water inlet 42 also extends in the second direction, when the product is buried in the wall, it will cause the wall to be buried too deep, increasing the construction cost. The extension of the water inlet 42 in a direction perpendicular to the second direction can reduce the length of the product in the second direction.

[0074] In this embodiment, there are two first valve core water inlet holes 411, and two water inlet channels 42 corresponding one to one with the first valve core water inlet holes 411. The two water inlet channels 42 are respectively suitable for inletting cold water and hot water, and can realize the temperature regulation function by cooperating with the corresponding thermostatic valve.

[0075] In this embodiment, the water passing member 1 is further provided with a third water passing portion 13, the third water passing portion 13 extends along the second direction and is connected to an end of the first water passing portion 11 away from the second water passing portion 12; the water passing channel 14 penetrates the third water passing portion 13, the second insert 3 is provided with a second hole 31, the second hole 31 is suitable for the third water passing portion 13 to extend into, and a third space 7 exists between the hole wall of the second hole 31 and the third water passing portion 13; a fourth space 8 exists between the second insert 3 and the first water passing portion 11;

[0076] The filling piece 4 also fills the third space 7 and the fourth space 8 .

[0077] Similarly, due to the existence of the third space 7 and the fourth space 8, the water-passing member 1 does not contact the second insert 3, and the filling member 4 fills the third space 7 and the fourth space 8 to connect the second insert 3 and the water-passing member 1, and there will be no overflow problem. The setting of the third water-passing portion 13 can reduce the length of the plug-in column on the mold that is plugged into the water-passing channel 14, thereby making the product processing simpler and less prone to damage, and reducing the demoulding force when forming the waterway on the plug-in column.

[0079] In this embodiment, the filling member 4 is also provided with a water outlet 44, which extends in a direction perpendicular to the second direction and is connected to the second valve core water outlet hole 432, thereby completing the water outlet waterway. The second direction is the direction of installing the valve core. If the water outlet 44 also extends in the second direction, when the product is buried in the wall, it will cause the wall to be buried too deep, increasing the construction cost. The extension of the water outlet 44 in a direction perpendicular to the second direction can reduce the length of the product in the second direction.

[0080] In this embodiment, there are at least two second valve core water outlet holes 432, and the water outlet channel 44 is connected to the second valve core water outlet holes 432 in a one-to-one correspondence, so that different water outlet waterways can be realized. The function of switching waterways can be realized by installing a switching valve at the second valve core mounting portion 43.

[0081] In this embodiment, the outer walls of the first insert 2 and the second insert 3 are both provided with threaded sections 22, which can be used for mounting with external parts and assembling with the mold during molding. Anti-overflow grooves 23 are provided at both ends of the threaded sections 22 to prevent resin from overflowing into the threaded sections 22.

[0082] In other embodiments, the openings at both ends of the water passage 14 can directly serve as the first valve core water outlet hole 412 and the second valve core water inlet hole 431 , and the filling member 4 does not need to be provided with the first valve core water outlet hole 412 and the second valve core water inlet hole 431 .

[0083] In other embodiments, the second insert 3 may not be provided, and the openings at both ends of the water passage 14 may be used for the first valve core water outlet 412 and the water outlet, respectively.

[0084] In other embodiments, the water pass member 1 is strip-shaped, and the water pass member 1 is only provided with a first water pass portion 11 and a water pass channel 14 passing through the first water pass portion 11, and is not provided with a second water pass portion 12 and a third water pass portion 13, and the two openings of the water pass channel 14 face the first hole 21 and the second hole 31 respectively.

[0085] In other implementations, the water flow member 1 may be L-shaped, and the water flow member 1 is provided with only one of the first water flow portion 11 , the second water flow portion 12 and the third water flow portion 13 .
