DETAILED DESCRIPTION
[0028] The present application will be further described in detail below in combination with the drawings and specific embodiments.
[0029] The present application relates to a floor drain cover 1, as shown in Figures 1-2 , comprising an upper cover body 11 and a lower cover body 12, the upper cover body 11 and the lower cover body 12 are relatively rotatably connected by a center rotating structure.
[0030] The upper cover body 11 is provided with a first drain hole group 111, and the lower cover body 12 is provided with a second drain hole group 121 corresponding to the first drain hole group 111. The upper cover body 11 and the lower cover body 12 can be relatively rotated to completely overlap the first drain hole group 111 and the second drain hole group 121 to form a maximum drainage opening (as shown in Figure 1
[0031] The new floor drain cover 1 can form different use states of maximum drainage opening, adjusted drainage opening and complete sealing by relatively rotating the upper cover body 11 and the lower cover body 12 through the center rotating structure. Not only the stepless flow regulation function is realized, but also the floor drain cover 1 itself can play the role of deodorization and mosquito prevention in the completely closed state, which can meet the practical needs of different application scenarios. When the user installs the floor drain cover 1 or needs to adjust the use state of the floor drain cover 1, only the upper cover body 11 and the lower cover body 12 need to be relatively rotated, which is simple in structure and easy to operate. The new floor drain cover is particularly suitable for balcony scenes. The drain hole on the existing floor drain cover is easy to be blocked by entering sundries and is easy to attract mosquitoes or cause backflow and odor, and the use of the new floor drain cover can well avoid such situations.
[0032] As a preferred scheme, the upper cover body 11 and the lower cover body 12 are arc-shaped curved surface structures with outwardly convex matching outer surfaces, and the first drain hole group 111 and the second drain hole group 112 are uniformly distributed along the circumferential direction of the arc-shaped curved surface.
[0033] By adopting the above scheme, on the one hand, it is beneficial to the drainage of the floor drain cover, and it prevents the accumulation of water and dirt on the surface, and on the other hand, the arc-shaped curved surface structure is adapted to the natural bending arc when the human hand holds it, which is beneficial to the user to rotate and adjust the floor drain cover 1 more labor-saving and accurately.
[0034] As a preferred scheme, the upper surface of the lower cover body 12 extends upward to form a cladding flange 122. The lower cover body 12 matches and clads the periphery of the upper cover body 11 through the cladding flange 122, which can be semi-cladding or full-cladding. On the one hand, this makes the structure of the upper and lower cover bodies of the floor drain cover more compact, and on the other hand, it is convenient for the assembly of the upper and lower cover bodies, and enhances the stability and reliability of the assembled structure.
[0035] As a preferred scheme, the center of the upper cover body 11 and the lower cover body 12 is respectively provided with a first annular drain 113 and a second annular drain 123, and the first annular drain 113 and the second annular drain 123 are nested and assembled with each other to form the center rotating structure therebetween.
[0036] Adopting the above scheme, the first annular drain outlet 113 and the second annular drain outlet 123 are nested with each other, and a central part constitutes a drain passage, so that the central rotating structure and the drain passage are spatially multiplexed, realizing the function integration of draining and rotating, wherein the draining function can be selected to be connected with a drain pipe according to actual application scenarios, or the drain pipe is not used by being blocked by a related matched plug, so as to meet the diversified needs of users and improve the practical performance of the floor drain cover.
[0037] Further, in the preferred embodiment of the central rotating structure, the bottom of the first annular drain outlet 113 extends to form an annular protrusion 1131, and the inner side of the second annular drain outlet 123 is formed with an annular clamping groove 1231 matched with the annular protrusion 1131, and the annular protrusion 1131 and the annular clamping groove 1231 are matched to constitute the central rotating structure. The central rotating structure adopts the structure of the annular protrusion 1131 and the annular clamping groove 1231, and does not need to be matched with other components, so that the assembly operation is very simple and convenient, the structure is stable and firm, and the large shaft diameter matching of the central rotating structure is formed due to the relatively large diameter of the drain outlets, so that excellent mutual rotating performance is formed.
[0038] Further, the inner side of the first annular drain outlet 113 is provided with an internal thread 1132, which is beneficial to the connection of external pipelines or matched plugs.
[0039] Further, the bottom of the second annular drain outlet 123 extends to form a connecting section 124, and the connecting section 124 is provided with a thread, specifically an external thread 1241, which is beneficial to the connection of the floor drain cover with the floor drain body in application.
[0040] The utility model also provides a floor drain, as shown in the figure, Figures 3-4 The existing floor drain body 2 has a floor drain core 22, and the floor drain core has a sealing function, so that the floor drain of the utility model is respectively provided with two sealing barriers on the floor drain cover 1 and the floor drain body 2, and in the case that the floor drain does not drain, the floor drain can well realize the effects of deodorization, anti-reflux and mosquito prevention.
[0041] As a preferred scheme, the central parts of the upper cover body 11 and the lower cover body 12 are respectively provided with the first annular drain outlet 113 and the second annular drain outlet 123, the first annular drain outlet 113 and the second annular drain outlet 123 are nested and assembled with each other, and the first annular drain outlet 113 on the inner side forms a connecting port. Figure 5As shown, the floor drain can be connected with a sewer connector 4 through the connecting port in application, and the sewer connector 4 can be a two-way, three-way or multi-way connector according to actual needs, so as to connect at least one sewer pipe on the floor drain to realize the effect of centralized sewerage of the ground and the pipe.
[0042] As a preferred solution, the floor drain body 2 comprises a connecting body 21 and a floor drain core 22, and the connecting body 21 is connected between the floor drain cover 1 and the floor drain core 22. The side surface of the connecting body 21 is provided with at least one drain port 211, and a movable baffle 3 is arranged at the inner side of the connecting body 21 corresponding to the drain port 211. As shown Figure 3 As shown, the movable baffle 3 is closed to the drain port 211 in the natural state, the water body enters from the sewer hole 11 of the floor drain cover 1, the water flow pressure pushes the movable baffle 3 to open the drain port 211, and the water body flows from the outside to the inside of the drain port 211 and finally enters the connecting body 21.
[0043] With the above solution, the connecting port and the sewer hole 11 form a double-channel sewer structure, the connecting port realizes pipe sewerage through the sewer connector 4, and the sewer hole 11 realizes indoor ground sewerage, and the two do not affect each other. When the ground is sewered, the water flow forms an impact force perpendicular to the movable baffle 3 when entering the drain port 211 to realize sewerage; when the ground is not sewered, the movable baffle 3 is in a natural state due to gravity and forms a radial seal with the drain port 211. When the pipe is sewered, the movable baffle 3 can well avoid the problem of possible backflow of the sewer flow from the sewer hole of the floor drain cover due to the shielding and sealing of the movable baffle 3, thereby the new floor drain widens the floor drain sewerage connection function, and well balances the multi-pipe sewerage performance and the overall odor prevention and backflow prevention performance.
[0044] The above is only a preferred embodiment of the new type, and any equivalent changes and modifications made within the scope of the claims of the new type should belong to the scope of the claims of the new type.
