The concealed embedded box of the above structure has the following problems: since the concealed embedded box needs to be tested for leakage after being installed on the wall, and the leakage test specifically requires the water outlet of the metal body to be blocked, and then the water inlet is opened and a certain pressure test is performed, it is inevitable that some debris such as sand and gravel will enter the water pipe during the decoration period, so during the leakage test, the sand and gravel and other debris will enter the valve core assembly with the water flow and damage it, and in serious cases, it may need to be re-purchased, and the valve core assembly is relatively expensive, so it will cause a large loss to the user.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] like Figure 1-12 As shown, a water control connection device that can be pre-buried in a wall provided by an embodiment of the present invention is shown. Figure 2-10, which at least includes a box body 1, a water inlet pipe 2, a water outlet pipe 3, a leak detection component 4 and a valve core assembly 5; the valve core assembly 5 is detachably connected to the box body 1, and the leak detection component 4 is detachably connected to the box body 1; a first conduction port 411 and a second conduction port 412 are opened on the surface of the leak detection component 4, and the first conduction port 411 and the second conduction port 412 are connected through a conduction cavity 421 opened inside the leak detection component 4; a third conduction port 511 and a fourth conduction port 512 are opened on the valve core assembly 5, and the third conduction port 511 and the fourth conduction port 512 are connected The water inlet pipe 2 is fixedly connected to the box body 1, and the water inlet pipe 2 has a water inlet 21 and an outlet 22. The water inlet 21 is located outside the box body 1, and the outlet 22 is located inside the box body 1, and the outlet 22 is suitable for communicating with the first conductive port 411 or the third conductive port 511; the water outlet pipe 3 is fixedly connected to the box body 1, and the water outlet pipe 3 has a water outlet 32 ​​and an inlet 31. The water outlet 32 ​​is located outside the box body 1, and the inlet 31 is located inside the box body 1, and the inlet 31 is suitable for communicating with the second conductive port 412 or the fourth conductive port 512.

[0033] In the above-mentioned setting, the valve core assembly 5 is detachably connected to the box body 1, and the leak detection part 4 is also detachably connected to the box body 1; in this way, when leak detection is performed, the valve core assembly 5 can be separated from the box body 1, and the leak detection part 4 can be connected to the box body 1 for leak detection, thereby avoiding the possibility of damage to the valve core assembly 5 during leak detection. In addition, since the valve core assembly 5 is located outside the wall and is used frequently, its aging speed is faster. Through the detachable connection method of the present invention, only the valve core assembly 5 can be taken out for replacement without taking out the water inlet pipe 2 and the water outlet pipe 3, which is very convenient.

[0034] Specifically, the actual use process of the present invention is as follows: install the box body 1 in the pre-buried hole on the wall, connect the external water pipe to the water inlet 21 of the water inlet pipe 2 of the present invention, connect the leak detector 4 to the box body 1, make the outlet 22 communicate with the first conduction port 411 on the leak detector 4, and the second conduction port 412 on the leak detector 4 communicate with the inlet 31, block the water outlet 32 ​​of the outlet pipe 3 through the plugging member, open the water flow of the external water pipe and start leak detection. After the leak detection is completed, remove the leak detector 4, and then connect the valve core assembly 5. When the valve core assembly 5 is connected, the outlet 22 needs to be connected with the third conduction port 511 of the valve core assembly 5, and the fourth conduction port 512 of the valve core assembly 5 needs to be connected with the inlet 31.

[0035] It should be noted that the number of water inlet pipes 2 can be multiple. In the present invention, it is preferably two, namely the hot water inlet pipe 2 and the cold water inlet pipe 2. Similarly, the number of water outlet pipes 3 can also be multiple, and the present invention is always preferably three. When the number of water inlet pipes 2 and water outlet pipes 3 is multiple, it is necessary to match the number of the first conductive port 411, the second conductive port 412, the third conductive port 511 and the fourth conductive port 512 with the number of outlets 22 and inlets 31. Specifically as follows: the number of the first conductive port 411 and the third conductive port 511 matches the number of outlets 22, and the number of the second conductive port 412 and the fourth conductive port 512 matches the number of inlets 31.

[0038] Preferably, refer to Figure 2-3 A stop valve 23 is provided in the water inlet pipe 2, and the stop valve 23 is used to control the on-off of the water inlet 21 and the outlet 22. By providing the stop valve 23, when the valve core assembly 5 needs to be repaired or replaced, the stop valve 23 can be closed to isolate the water inlet 21 from the outlet 22. In this way, the valve core assembly 5 can be repaired or replaced without closing the external water pipe, which is very convenient.

This design is to facilitate process production, and the second surface of the bottom plate 41 is a plane and the sealing plane of the conducting plate 42 cooperates with each other to enhance the sealing effect. Specifically, the conducting cavity 421 can also be provided with reinforcing ribs, and the edge of the conducting cavity 421 can also be provided with a waterproof rubber ring to further enhance the sealing effect.

[0040] Preferably, a first sealing groove 413 is provided at the first conducting opening 411, and a second sealing groove 414 is provided at the second conducting opening 412; a sealing ring 6 is provided in each of the first sealing groove 413 and the second sealing groove 414. In this way, the sealing of the connection between the first conducting opening 411 and the outlet 22 and the sealing of the second conducting opening 412 and the inlet 31 can be ensured.

[0041] Preferably, a third sealing groove 513 is provided at the third conducting opening 511, and a fourth sealing groove 514 is provided at the fourth conducting opening 512; a sealing ring 6 is provided in each of the third sealing groove 513 and the fourth sealing groove 514. Similarly, by such a configuration, the sealing of the connection between the third conducting opening 511 and the outlet 22 and the sealing of the fourth conducting opening 512 and the inlet 31 can be ensured.

[0042] Preferably, the valve core assembly 5 is suitable for being screwed to the box body 1, and the leak detector 4 is suitable for being screwed to the box body 1. That is, in the present invention, the detachable connection mode between the valve core assembly 5 and the box body 1 is specifically screwed. The connection mode between the leak detector 4 and the box body 1 is also specifically screwed.

Specifically, the connection mode between the box body 1 and the extension box 7 is a snap connection. Through such a setting mode, the present invention can be expanded according to the use requirements. For example, when the number of water outlets 32 is insufficient, one or more extension boxes 7 can be added, so that the extension water outlet 82 of the water outlet connecting pipe 8 in the extension box 7 can meet the demand. It should be noted that when adding multiple extension boxes 7, the connection between the extension boxes needs to be connected, and of course, the connection between the extension boxes is also a detachable connection.

[0044] Preferably, the water outlet connecting pipe 8 is integrally injection molded with the expansion box 7. Similarly, this has the same effect as the integral injection molding of the water inlet pipe 2, the water outlet pipe 3 and the box body 1.
