[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] The following is based on the attached Figure 1-2The invention describes a floor drain valve core according to an embodiment of the utility model.

[0036] The floor drain valve core of the utility model embodiment comprises a main body 1, a first valve plate 2 and a connecting pipe 3. The main body 1 has a first chamber 101, a water inlet 4 connecting the first chamber 101 and the outside is arranged on the side wall of the main body 1, the wall surface of the first chamber 101 adjacent to the water inlet 4 is an inclined surface, and a water outlet 5 connecting the first chamber 101 and the outside is arranged at the lower end of the main body 1; the first valve plate 2 is arranged in the first chamber 101 and the upper end of the first valve plate 2 is rotatably connected to the main body 1, so that the first valve plate 2 can rotate from the second position of opening the water inlet 4 to the first position of closing the water inlet 4 by its own weight; the connecting pipe 3 is connected to the water outlet 5.

[0037] The present application arranges a water inlet 4 on the side wall of the main body 1 and arranges a first valve plate 2 inside the main body 1 that can close the water inlet 4 by its own weight. On the one hand, the water inlet 4 arranged on the side wall can allow waste water to quickly enter the first chamber 101 and be discharged from the water outlet 5; on the other hand, the first valve plate 2 that can close the water inlet 4 by its own weight has a simple structure and can automatically close the water inlet 4 at any time without the need to arrange other components, thereby effectively preventing the odor from the sewer pipe from returning.

[0038] Therefore, the floor drain valve core of the embodiment of the utility model has the characteristics of simple structure, rapid drainage and effective prevention of odor from returning.

[0039] The following is combined with Figure 1-2 The floor drain valve core of the embodiment of the utility model is further described.

[0040] like Figure 1 and 2 As shown, the floor drain body 1 of the embodiment of the utility model is a shell with a closed upper end and openings on the side wall and the lower end. In other words, the body 1 has a first chamber 101, and a water inlet 4 connecting the first chamber 101 and the outside is arranged on the side wall of the body 1. The wall surface of the first chamber 101 adjacent to the water inlet 4 is an inclined surface, and the lower end of the body 1 is provided with a water outlet 5 connecting the first chamber 101 and the outside;

[0041] like Figure 2 As shown, the first valve plate 2 is disposed in the first chamber 101 and the upper end of the first valve plate 2 is rotatably connected to the main body 1, so that the first valve plate 2 can rotate from the second position opening the water inlet 4 to the first position closing the water inlet 4 by its own weight.

[0042] In order to enable the first valve plate 2 to quickly rotate from the second position opening the water inlet 4 to the first position closing the water inlet 4, the thickness of the first valve plate 2 can be gradually reduced from bottom to top, that is, the thickness of the first valve plate 2 gradually becomes thinner from bottom to top, so that the center of gravity of the first valve plate 2 is located at the lower part of the first valve plate 2, thereby, the first valve plate 2 can quickly rotate from the second position opening the water inlet 4 to the first position closing the water inlet 4, that is, the first valve plate 2 can quickly close the water inlet 4 to prevent the odor of the sewer pipe from returning.

[0043] By making the wall surface of the first chamber 101 adjacent to the water inlet 4 into an inclined surface, the first valve plate 2 can fit with the inclined surface. On the one hand, it can better prevent odor from overflowing from between the first valve plate 2 and the main body 1, and on the other hand, it can make the first valve plate 2 fit more closely with the inclined surface under the action of its gravity.

[0044] It is understandable that in order to prevent the first valve plate 2 from fitting against the top wall of the main body 1 when in the second position, thereby being adsorbed on the top wall of the main body 1 under the action of water and unable to rotate to the first position, a limiting protrusion 7 is provided on the inner side of the first valve plate 2.

[0045] like Figure 2 As shown, there are two water inlets 4 , which are symmetrically arranged on the side wall of the main body 1 .

[0046] like Figure 2 As shown, the main body 1 is in the shape of an inverted cone.

[0047] like Figure 2 As shown, the connecting pipe 3 is arranged at the lower end of the main body 1 and is connected to the water outlet 5. The connecting pipe 3 can be connected to the sewer pipe to discharge the waste water into the sewer pipe.

[0048] In order to enable the connecting pipe 3 to be better connected to the sewer pipe, an annular groove 6 is provided on the outside of the connecting pipe 3 . The annular groove 6 extends circumferentially along the connecting pipe 3 , and a sealing ring 9 is provided in the annular groove 6 .

[0049] Optionally, there are multiple annular grooves 6 , and the multiple annular grooves 6 are arranged at intervals along the axial direction of the connecting pipe 3 .

[0050] The connecting pipe 3 of the embodiment of the utility model is provided with a sealing ring 9 in the annular groove 6 on the outer side thereof, so that the sealing ring 9 can seal between the connecting pipe 3 and the sewer pipe, further preventing the odor in the sewer pipe from overflowing.

[0051] In some embodiments, a water guiding notch 8 is provided at the upper portion of the main body 1 corresponding to the water inlet 4 .

[0052] The floor drain valve core of the utility model embodiment is provided with a water guide notch 8 corresponding to the water inlet 4 at the upper part of the main body 1, which can accelerate the flow of waste water into the water inlet 4 and into the first chamber 101, thereby improving the drainage rate.

[0053] In some embodiments, a gripping notch 10 is further provided on the upper portion of the main body 1 .

[0054] Alternatively, if Figure 2 As shown, there are two gripping notches 10, and the two gripping notches 10 are symmetrically arranged.

[0055] The floor drain valve core of the embodiment of the utility model is provided with two holding notches 10, so that the user can hold it conveniently, and then the floor drain valve core can be installed on the sewer pipe.

[0056] In some embodiments, a protrusion is disposed on the upper surface of the main body 1 .

[0057] Optionally, the protrusion 11 is disposed at the center of the upper surface of the main body 1 , so as to prevent water from accumulating on the upper surface of the main body 1 .
