[0039] Next, in combination with the specific implementation manners of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present utility model, rather than all of the implementation manners. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0040] As Figures 1-5 shown, a buried vertical pipe connector with a confluence function according to the present utility model includes a buried box 1, two confluence pipes 2 and an anti-reverse member 3, which are used for being buried in the building floor. It can not only connect two drainage vertical pipes on the upper and lower sides of the floor, but also connect the indoor horizontal drainage collection pipe with the drainage vertical pipe.

[0041] Among them, the buried box 1 is the main structure of this connector and is buried in the building floor. A water storage cavity 101 is provided in the buried box 1. A water inlet 102 and a water outlet 103 are opened on the buried box 1, and the water inlet 102 and the water outlet 103 are connected through the water storage cavity 101. The water inlet 102 and the water outlet 103 are respectively used for connecting with the drainage vertical pipe above the floor and the drainage vertical pipe below the floor. The water inlet 102 is usually opened on the top side of the buried box 1, the water outlet 103 is usually opened on the bottom side of the buried box 1, and the water inlet 102 and the water outlet 103 are coaxially arranged.

[0042] The confluence pipe 2 is used to connect with the horizontal drainage pipe in the room. One end of the confluence pipe 2 is sealed and fixed on the embedded box 1 and communicates with the water storage cavity 101, and the other end is parallel to the horizontal plane. After the horizontal drainage pipe communicates with the end of the confluence pipe 2 away from the embedded box 1, the sewage flows from the horizontal drainage pipe through the confluence pipe 2 into the water storage cavity 101, and then enters the drainage riser connected to the water outlet 103. The drainage riser is usually installed on one side of the indoor wall or at the corner of the room. The opening directions of the two confluence pipes 2 away from the embedded box 1 are opposite. During the embedding process of the embedded box 1, at most the opening of one confluence pipe 2 is blocked by the wall, that is, at least one opening of the confluence pipe 2 can be away from the wall, so as to facilitate the connection between the confluence pipe 2 and the horizontal drainage pipe and improve the installation convenience of the two.

[0043] As Figure 1 and Figure 3 shown, the confluence pipe 2 includes a vertical section 21 and a horizontal section 22. One end of the vertical section 21 is sealed and fixed on the top side of the embedded box 1 and communicates with the water storage cavity 101, and its center line is perpendicular to the horizontal plane. One end of the horizontal section 22 is sealed and fixed and communicates with the end of the vertical section 21 away from the embedded box 1, and the center line of the horizontal section 22 is parallel to the horizontal plane. The confluence pipe 2 adopts an L-shaped tubular structure, and one end of it is arranged on the top side of the embedded box 1, which can make the sewage in the horizontal drainage pipe and the confluence pipe 2 flow completely into the embedded box 1.

[0044] The two confluence pipes 2 are symmetrically arranged about the center line of the embedded box 1, which not only makes the openings of the two confluence pipes 2 face in opposite directions, but also makes the two confluence pipes 2 coaxial, so that the connector has symmetry and balance.

[0045] The anti-reverse member 3 is used to prevent mosquitoes or odors in the embedded box 1 from flowing back into the horizontal drainage pipe, without affecting the sewage in the horizontal drainage pipe from flowing into the embedded box 1. The anti-reverse member 3 is detachably fixed in one of the confluence pipes 2. Only one anti-reverse member 3 is provided, that is, the anti-reverse member 3 is arranged in the confluence pipe 2 connected to the horizontal drainage pipe, and the other confluence pipe 2 is not provided with the anti-reverse member 3 and is blocked.

[0046] The anti-reverse member 3 has various structures, similar to the inner core of a floor drain, including a water seal type, a rubber duckbill type, etc. As a preferred implementation manner, the anti-reverse member 3 includes a sealing cylinder 31 and a plug plate 32, as Figure 1 and Figure 4As shown, the sealing cylinder 31 is detachably fixed in one of the manifold pipes 2 and is sealingly connected thereto; the upper end of the plug plate 32 is rotatably arranged at one end of the sealing cylinder 31 close to the embedded box 1 and seals the sealing cylinder 31; in the natural state, the plug plate 32 seals the sealing cylinder 31 to prevent sewage or gas in the water storage cavity 101 from passing through the manifold pipe 2. When the sewage in the horizontal drainage pipeline flows into the manifold pipe 2, it can impact the plug plate 32, causing the plug plate 32 to rotate, so that the plug plate 32 loses its sealing effect on the sealing cylinder 31, allowing the sewage to flow into the water storage cavity 101.

[0047] As Figure 4 shown, the end of the sealing cylinder 31 away from the embedded box 1 is perpendicular to the horizontal plane, and the end close to the embedded box 1 is inclined. The distance from the end of the sealing cylinder 31 close to the embedded box 1 to the end away from the embedded box 1 gradually increases from top to bottom, so that the plug plate 32 can fit more closely to the end of the sealing cylinder 31 in the natural state, improving its sealing performance.

[0048] As Figure 5 shown, the sealing cylinder 31 includes a cylinder body 311 and a fixing frame 312, and the plug plate 32 includes a rotating shaft 321 and a sealing plate 322. The cylinder body 311 is detachably fixed in one of the manifold pipes 2 and is sealingly connected thereto; the fixing frame 312 is fixedly arranged at one end of the cylinder body 311 close to the embedded box 1, and a rotating hole 301 is formed inside it; the rotating shaft 321 is rotatably arranged in the rotating hole 301; the sealing plate 322 is fixedly arranged on the rotating shaft 321 and sealingly abuts against one end of the cylinder body 311 close to the embedded box 1. By rotating the rotating shaft 321 in the rotating hole 301, the sealing plate 322 can seal and move away from the cylinder body 311; an opening and closing groove 302 is formed on one side of the fixing frame 312 close to the embedded box 1, and the opening and closing groove 302 communicates with the rotating hole 301. The outer diameter of the rotating shaft 321 is slightly larger than the inner diameter of the opening and closing groove 302. Under normal conditions, the rotating shaft 321 is rotatably arranged in the rotating hole 301. When there is a problem with the sealing plate 322, an external force can be applied to the rotating shaft 321 to move the rotating shaft 321 out of the rotating hole 301 through the opening and closing groove 302, facilitating the replacement of the plug plate 32.

[0049] As Figure 2As shown in the figure, the embedded box 1 includes a box body 11, a water inlet pipe 12, a water outlet pipe 13 and a water seal pipe 14. A water storage cavity 101 is arranged inside the box body 11. The water inlet pipe 12 penetrates and is fixedly arranged on the top side of the box body 11 and is hermetically connected thereto. A water inlet 102 is arranged inside the water inlet pipe 12. The water outlet pipe 13 penetrates and is fixedly arranged on the bottom side of the box body 11 and is hermetically connected thereto. A water outlet 103 is arranged inside the water outlet pipe 13. The lower end of the water inlet pipe 12 is located inside the water outlet 103, and the outer side of the water inlet pipe 12 is spaced from the inner wall of the water outlet 103. Sewage flowing into the water storage cavity 101 through the confluence pipe 2 can flow into the water outlet pipe 13 along the space between the water inlet pipe 12 and the water outlet 103, so as to confluence the sewage in the confluence pipe 2 into the drainage vertical pipe.

[0050] One end of the water seal pipe 14 is fixedly arranged on the top side inside the water storage cavity 101, and the other end is spaced from the bottom side inside the water storage cavity 101. The upper end of the water outlet pipe 13 is located inside the water seal pipe 14, and the outer side of the water outlet pipe 13 is spaced from the inner wall of the water seal pipe 14. As Figure 2 shown, when the liquid level of the sewage in the water storage cavity 101 is higher than the bottom end of the water seal pipe 14, it will cooperate with the water seal pipe 14 and the water outlet pipe 13 to form a water seal structure, so as to perform secondary sealing on the inside of the water storage cavity 101 and prevent peculiar smell from entering the horizontal drainage collecting pipe from the drainage vertical pipe.

[0051] As Figure 2 shown, an annular groove 104 is formed in the bottom side of the water outlet pipe 13. The annular groove 104 is a groove-shaped structure with a circular cross-section. The top end of the drainage vertical pipe below the ground can be inserted into the annular groove 104, thereby improving the connection tightness between the drainage vertical pipe and the embedded box 1 and the adaptability of the embedded box 1 to drainage vertical pipes of different specifications.

[0052] The using method of an embedded vertical pipe connector with a confluence function of the present utility model is as follows:

[0053] First, embed the embedded box 1 in the building ground, and make the water inlet 102 and the water outlet 103 correspond to the installation positions of the drainage vertical pipes. Then, install the anti-reverse member 3 in one of the confluence pipes 2 away from the wall and block the other confluence pipe 2. Finally, connect the water inlet 102 and the water outlet 103 to two sections of drainage vertical pipes, and connect the confluence pipe 2 installed with the anti-reverse member 3 to the horizontal water supply pipe.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
