Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a multifunctional drainage floor drain. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an indispensable and important part of the drainage system, it is widely used. The floor drain can not only drain water, but also filter some debris in the water to protect the drainage system.

[0003] In construction activities, the floors of rooms with water are mostly tiled. The laying of tiles is mostly done by dry mortar technology. After the dry mortar is formed, the porosity is large and it is easy to accumulate water. Ordinary drainage floor drains only drain the upper surface of the ground. The waterproof protective layer of the room with water is still some distance away from the tile floor. During production and life use, water is retained between the waterproof layer and the tile floor for a long time and cannot be removed. Over time, it is easy to produce odor and breed bacteria. Utility Model Content

[0004] The purpose of the utility model is to solve the defect that the existing water retained between the waterproof layer and the ground cannot be discharged, and a floor drain for discharging the water retained between the waterproof layer and the ground is proposed;

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A floor drain for draining water retained between a waterproof layer and the ground, comprising a floor drain shell, an air bag installed in the floor drain shell, and a floor drain core, wherein the floor drain shell comprises a water seepage hole, an upper wing ring, a lower wing ring, a fixing plate, and a floor drain shell thread for installing the floor drain core, and the floor drain core comprises a screw head, a drainage grid, and a floor drain core thread for installation, and the air bag is a hollow circular ring with an elliptical cross section, which can effectively prevent backflow water and prevent the backflow water from entering the room through the floor drain;

[0007] The water seepage hole is a circular hole;

[0008] The diameter of the fixing plate is larger than the diameter of the upper wing ring and the diameter of the lower wing ring. When the floor slab is poured with concrete, the lower wing ring is buried in the concrete and combined with the cast-in-place concrete floor slab to achieve a fixing effect;

[0009] The floor drain shell comprises a seepage hole, a lower wing ring, an upper wing ring, a floor drain shell thread, and a fixing plate, which is fixed to the corresponding position of the template as an embedded part before pouring the concrete floor slab. During the waterproof construction, the waterproof layer is overlapped with the upper wing ring to ensure the integrity of the waterproof layer. During the installation of the floor drain, the air bag is placed in the floor drain shell, and the floor drain core is installed in the floor drain shell by twisting the screw head;

[0010] As for the utility model, the floor drain shell, the air bag and the floor drain core are all integrally formed, and the overall plastic product, and the upper wing ring can be customized in height according to the different thicknesses of the floor slab. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example: Figures 1 to 9 The figure is only one embodiment of the present utility model, a floor drain for discharging water retained between a waterproof layer and the ground, comprising a floor drain housing 5, an air bag 4 installed in the floor drain housing, and a floor drain core 3, wherein the floor drain housing 5 comprises a water seepage hole 6, an upper wing ring 8, a lower wing ring 7, a fixing plate 16, and a floor drain housing thread 15 for installing the floor drain core, the floor drain core 3 comprises a screw head 1, a drainage grille 2, and a floor drain core thread 14 for installation, and the air bag 4 is a hollow circular ring with an elliptical cross section;

[0028] During the construction activities, after the installation of the house floor formwork 18 is completed, the floor drain housing 5 is fixed on the formwork as an embedded part by nails 17 and fixing plates 16, and then concrete is poured. During the waterproof construction process, the waterproof material 11 is overlapped and connected with the upper wing ring 8 to ensure the integrity of the waterproof. When the tile 9 is laid, dry mortar 10 can be used to lay it. The upper surface of the tile 9 is flush with the upper surface of the floor drain housing 5, and the tile is overall sloped;

[0029] After the above-mentioned steps are completed, the drain pipe 13 can be installed, the floor drain shell 5 and the drain pipe 13 are connected by gluing and spigot, the air bag is placed inside the floor drain shell 5, and then the floor drain core 3 is installed by threading. The installation of the floor drain core 3 and the air bag 4 can be constructed simultaneously with the drain pipe 13;

[0030] After the floor drain is installed, the floor drain core 3 can be removed by screwing the head 1 for cleaning and replacement. If the airbag 4 is damaged, the floor drain core 3 can be removed and replaced by disassembling it.

[0031] The floor drain shell 5 itself forms a water seal, and the air bag 4 blocks the water outlet of the floor drain core 3 during non-draining time, forming a double seal;

[0032] The drainage grille 2 can effectively block large debris carried in the drainage and protect the drainage system. After the water flows into the floor drain through the drainage grille 2, the water is pressed down by the air bag 4 to flow into the floor drain housing 5, and then flows into the drainage pipe 13;

[0033] When water generated in production and life is retained between the waterproof material 11 and the tile 9, the water is discharged into the floor drain through the seepage hole 6 and finally discharged into the drainage system through the drain pipe 13.

[0034] It should be noted here that: in the absence of conflict, those skilled in the art can combine the relevant technical features in the above examples according to actual conditions.

[0035] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
