[0056] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0057] Embodiment

[0058] This embodiment provides a silent and detachable drainage pre-embedded device, as Figures 1-4 shown, including:

[0059] A water pipe connector 1 for connecting a building drainage pipe;

[0060] An anti-backflow floor drain assembly 2;

[0061] A connecting pipe 3, one end of which is connected to the water pipe connector 1 and the other end is connected to the anti-backflow floor drain assembly 2, so that the water in the anti-backflow floor drain assembly 2 can flow into the water pipe connector 1; both ends of the connecting pipe 3 are detachable structures;

[0062] The water pipe connector 1 includes:

[0063] A connector body 11;

[0064] The anti-backflow floor drain assembly 2 includes:

[0065] An anti-backflow floor drain assembly body 21;

[0066] A first inner tank 22 installed inside the anti-backflow floor drain assembly body 21. There is a gap between the outer side of the first inner tank 22 and the inner wall of the anti-backflow floor drain assembly body 21 through which water can flow. The first inner tank 22 has a water storage tank 221 capable of storing water. The upper end of the first inner tank 22 has a drain port 222 communicating with the inside of the anti-backflow floor drain assembly body 21; a ring-shaped protrusion 223 is provided at the center of the bottom of the water storage tank 221;

[0067] A second inner tank 23 installed inside the first inner tank 22, with both ends being through. The upper end can intake water, and the lower end can extend into the water remaining in the water storage tank 221. There is a gap between the outer side of the second inner tank 23 and the inner wall of the water storage tank 221 through which water can flow;

[0068] A floating ball 24, which is arranged in the water storage tank 221 and is located below the second inner tank 23. When the floating ball 24 floats, it can close the lower end of the second inner tank 23; the lower end of the floating ball 24 is conical, and the upper end is ellipsoidal with a protrusion at the vertex. When the floating ball 24 is in a non-floating state, the lower end is inserted into the ring-shaped protrusion 223, and the protrusion at the upper end vertex abuts against the inner wall of the lower end of the second inner tank 23.

[0069] For the silent and detachable drainage pre-embedded device of this embodiment, by setting the separated water pipe connector 1, anti-backflow floor drain assembly 2, and connecting pipe 3, the overall adjustment flexibility of the drainage device is improved. For different construction distances, only a connecting pipe 3 with a different length needs to be replaced. The connecting pipe is a conventional pipe fitting and is convenient to replace.

[0070] In the silent and detachable pre-embedded drainage device of this embodiment, the overall density of the float 24 is slightly smaller than that of water. Therefore, when the float 24 is fully submerged, it can float up to just against the lower opening of the second inner liner 23. The purpose of this structure is that when there is a problem with the sewage system of the building, such as sewage backflow, the water storage tank 221 gradually fills with sewage. At this time, the float 24 is completely submerged and floats up, blocking the lower opening of the second inner liner 23 and preventing further backflow; however, the float 24 does not affect the water inflow at the upper end of the second inner liner 23. When the upper end of the second inner liner 23 is normally filled with water, since the overall density of the float 24 is slightly smaller than that of water, it is not enough to float and cannot block the water from flowing downwards. Figure 4 As shown, there is a gap between the float 24 and the lower opening of the second inner container 23. Figure 4 As shown, since the float 24 has a special shape with a conical lower end and an ellipsoidal upper end, when it is not floating, the protrusion at the top of the upper end abuts against the inner wall of the lower end of the second inner liner 23, and the lower end is inserted into the annular protrusion 223. The sewage flowing in from the upper end of the second inner liner 23 is more easily concentrated in the gap between one side of the float 24 and the lower end of the second inner liner 23, and flows down along the conical surface of the lower end of the float 24. In this way, the noise during drainage is very small, which improves the user experience. Preferably, in order to ensure that the float 24 floats and falls normally, the upper end of the float 24 can be made hollow and the lower end can be made solid, which is easier to stand upright.

[0071] Preferably, in the silent, detachable, embedded drainage device of this embodiment, the water pipe connector 1 further comprises: a connection position adjustment ring 12 mounted on the upper end of the connector body 11, with a sealing gasket 13 disposed between the connection position adjustment ring 12 and the upper end of the connector body 11; the relative position between the connection position adjustment ring 12 and the connector body 11 can be adjusted within a certain range. This structure facilitates the adjustment of the connector body 11 within a certain range when connecting to a building water pipe.

[0072] Preferably, in the silent detachable pre-buried drainage device of this embodiment, a sealing ring 121 can be installed on the inner side of the connection position adjustment ring 12. The sealing ring 121 can prevent water leakage at the connection with the building water pipe.

[0073] Preferably, in the silent and detachable pre-buried drainage device of this embodiment, the upper end of the first inner liner 22 is connected to the anti-backflow floor drain assembly body 21 via a threaded connection. The threaded connection is easy to disassemble and has a strong sealing performance.

[0074] Preferably, the silent detachable drainage embedded device of this embodiment is as follows: Figure 3 As shown, the shape of the drain port 222 is a strip or a circle. The strip-shaped drain port has a large drainage flow rate, while the circular drain port is not easy to damage the structural strength of the first inner liner 22.

[0075] Preferably, for the silent detachable drainage embedded device of this embodiment, as Figure 5 shown, it further includes a sewage pipe 6 installed on the water pipe connector 1, and a maintenance opening 61 is provided on the sewage pipe 6. When the sewage pipe 6 is blocked, maintenance personnel can quickly check and repair it by opening the maintenance opening 61. Specifically, the maintenance opening 61 includes a base communicating with the main body part of the sewage pipe 6 and a lid covering the base, and the lid can be disassembled and assembled.

[0076] Preferably, for the silent detachable drainage embedded device of this embodiment, as Figure 1 shown, a floor drain cover 5 is provided at the upper end of the anti-backflow floor drain assembly 2, and the floor drain cover 5 has water leakage holes for water leakage. The floor drain cover 5 can block sundries and prevent large pieces of sundries from entering the water storage tank 221 and causing blockage.

[0077] Preferably, for the silent detachable drainage embedded device of this embodiment, as Figure 4 shown, the bottom of the water storage tank 221 is an arc surface.

[0078] Preferably, for the silent detachable drainage embedded device of this embodiment, the side wall of the second inner tank 23 is conical, and the diameter of the side wall of the second inner tank 23 gradually decreases from top to bottom. This facilitates the water flow to flow along the slope when flowing downward and reduces the flow sound of the water flow.

[0079] Preferably, for the silent detachable drainage embedded device of this embodiment, connecting pipe joints 4 are provided on opposite sides of the connecting seat main body 11 and the anti-backflow floor drain assembly main body 21. The inner end cross-section of the connecting pipe joint 4 is square, and the outer end cross-section is circular. Specifically, the inner end is in the shape of a quadrangular pyramid, and the width gradually becomes smaller from the inner side to the outer side. This shape can increase the flow rate of sewage discharge.

[0080] Preferably, for the silent detachable drainage embedded device of this embodiment, as Figure 1 shown, external threads are provided at both ends of the connecting pipe 3, and internal threads are provided at the outer ends of the connecting pipe joints 4 on the connecting seat main body 11 and the anti-backflow floor drain assembly main body 21; the connecting pipe 3 is threadedly connected to the connecting pipe joint 4. The threaded connection method is more convenient for disassembly and assembly.

[0081] Inspired by the above ideal embodiments based on this application, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
