[0001] The utility model relates to the technical field of floor drainage, in particular to a sealed floor drain with a mesh frame. Background Art
[0002] The existing ground drainage structure has the following defects:
[0003] First, traditional floor drainage structures require a gasket at the bottom to achieve sealing. The gasket and the shell must be glued or injection molded twice to fit together, resulting in low production efficiency and high costs.
[0004] Second, when the drain pipe is installed with a 90-degree flat elbow, due to the low installation height of the drain pipe, when the drainage structure is installed, the bottom of the drainage structure will be stuck at the 90-degree bend, causing the entire drainage component to be unable to open and drain properly, affecting the normal use of the product. Figure 11 As shown;
[0005] Third, after the inner core of the traditional ground drainage structure is installed and used for a period of time, various impurities will accumulate around the threads, making it difficult to remove the inner core of the drainage structure.
[0006] Therefore, the utility model proposes a sealed floor drain with a mesh frame. Utility Model Content

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the scope of protection of the present invention is not limited to the described scope. Example 1
[0039] like Figure 1 As shown, a sealed floor drain with a mesh frame includes a core body, the core body includes a shell assembly and a sealing plate assembly, the shell assembly includes a shell body 1 with openings at the upper and lower ends, a hair-blocking net 2 is provided at the upper end of the shell body 1, and a special-shaped pad 3 is provided on the outer surface of the lower port of the shell body 1, the sealing plate assembly includes a accommodating chamber body 4 and a sealing plate 5 arranged on one side of the accommodating chamber body 4, a gravity block is provided inside the accommodating chamber body 4, the sealing plate 5 is integrally connected with the accommodating chamber body 4, and the sealing plate 5 is rotatably connected to the lower port of the shell body 1, specifically through a rotating shaft. When water flows gather and enter the shell body 1, the sealing plate 5 can be pushed open under the action of the gravity of the water, and the accommodating chamber body 4 can be driven to rotate upward.
[0040] like Figure 5-6As shown in Figure 13, the lower end opening surface of the shell body 1 is provided with a first mounting groove 6 and a second mounting groove 7 near the inside and the outside respectively, and the inner wall surface of the special-shaped gasket 3 is provided with a first convex surface 8 and a second convex surface 9 that match the size of the first mounting groove 6 and the second mounting groove 7. The special-shaped gasket 3 is respectively installed in the first mounting groove 6 and the second mounting groove 7 through the first convex surface 8 and the second convex surface 9, which effectively prevents the special-shaped gasket 3 from falling off. The sealing plate 5 blocks the lower end opening of the shell body 1, so that the upper surface of the sealing plate 5 is in close contact with the special-shaped gasket 3, thereby realizing the sealing of the core body and avoiding the problem of traditional sealing gaskets and shells requiring glue or secondary injection molding.
[0041] like Figure 3 and 7 As shown, a supporting surface 10 for installing the hair-blocking net 2 is provided on the inner wall of the shell body 1. The hair-blocking net 2 includes a hair-blocking net body 11. An outer circular surface 12 is provided at the edge of the hair-blocking net body 11 along its circumferential direction. A limiting surface 13 that matches the size of the outer circular surface 12 is provided on the inner wall of the shell body 1 from the supporting surface 10 to the upper end opening of the shell body 1. When the hair-blocking net 2 is installed on the supporting surface 10, the supporting surface 10 cooperates with the lower surface of the hair-blocking net body 11 to limit the radial movement of the hair-blocking net; the cooperation between the outer circular surface 12 and the limiting surface 13 limits the axial movement of the hair-blocking net 2.
[0042] like Figure 2 and Figure 5 As shown, a group of external threads 14 are provided on the outer surface of the shell body 1 near its upper end opening, and a thread cone 15 is provided on the outer surface of the shell body 1 adjacent to the uppermost external thread 14 for locking the core body and the body.
[0043] A sealing ring installation groove is provided on the outer surface of the housing body 1 at the lowermost external thread 14 , wherein the sealing ring is installed in the groove.
[0044] like Figure 5 As shown, a guide angle 18 is provided at the lower end opening of the shell body 1 near the second installation groove 7 to facilitate the installation of the special-shaped pad 3, and the special-shaped pad 3 can be easily installed into the first installation groove 6.
[0045] like Figure 8 As shown, in this embodiment, an air duct 19 is provided on the lower surface of the sealing plate 5. When there is air pressure in the drainage pipe, a certain wind pressure is gathered in the air duct 19 under the action of the air pressure, so that the odor in the pipe cannot enter the room, giving the user a comfortable experience.
[0046] When the core body has a height of 3.8-4.5 cm, the end surface of the lower port of the shell body 1 is a plane.
[0047] like Figure 1As shown, in this embodiment, two support ears 16 are symmetrically provided on both sides of the open end surface of the upper end of the shell body 1, and connecting holes are opened on the two support ears 16. First handles 17 are installed in the two connecting holes, making cleaning and washing more convenient; it avoids the problem that after the inner core of the traditional floor drainage structure is installed and used for a period of time, various impurities will accumulate around the thread, making the inner core difficult to take out.
[0048] like Figure 4 As shown, a mounting groove 20 is provided on the upper portion of each connecting hole. When installing the sealing plate 5, the supporting shaft can be placed inside the mounting groove 20 first, and then the sealing plate 5 can be easily installed into place with a light press. Example 2
[0049] The difference between the mesh frame sealed floor drain of Example 2 and the mesh frame sealed floor drain of Example 1 is that:
[0050] like Figure 2 As shown, the core body height is 2.5-3.5cm. When used under the condition of installing a 90-degree PVC flat pipe drain pipe, it will not affect the drainage speed and avoid the problem that the bottom of the drainage structure will be stuck in the 90-degree bend, causing the entire drainage component to be unable to open and unable to drain normally, affecting the normal use of the product.
[0051] like Figure 9 As shown, a second handle 21 is provided inside the shell body 1, which avoids the problem that after the inner core of the traditional floor drainage structure is installed and used for a period of time, various impurities will accumulate around the thread, making it difficult to take out the inner core.
[0052] like Figure 10 As shown, to ensure a good seal, the end face of the lower port of the housing body 1 is tilted downward. This tilted surface of the port mates with the end face of the shaped gasket 3 installed at the lower end of the housing body 1, achieving a seal. After the shaped gasket 3 is installed, the second convex surface 9 is higher than the tilted surface of the lower port of the housing body 1. This allows the sealing plate 5 and the housing body 1 to form a sealing plane under the action of the shaped gasket 3, preventing odors from the drain pipe from entering the room.
[0053] The core body in Example 2 is lower than the core body in Example 1. The floor drainage device in Example 2 can be used under the condition of installing a 90-degree PVC flat pipe elbow 22, such as Figure 12 As shown, it will not affect the drainage speed.
[0054] The utility model has good filtering effect, good sealing and deodorizing effect, simple structure, convenient operation, easy installation and disassembly, and has the beneficial effects of improving indoor air quality.
