[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0025] Reference Figure 1 — Figure 2As shown, the large flow double seal floor drain of this embodiment includes a floor drain shell 1 and a cover plate 11 arranged on the floor drain shell 1 body, the floor drain shell 1 is provided with a sealing portion 12, the cross section of the inner side of the sealing portion 12 is square, and the sealing portion 12 is provided with a first sealing component 2 and a second sealing component 3, the first sealing component 2 is located on the upper side of the second sealing component 3, and the first sealing component 2 includes:
[0026] A first closing plate 21 is rotatably arranged on the side of the floor drain shell 1, and the first closing plate 21 is inclined;
[0027] A first sealing block 22, fixedly connected to the first closing plate 21, and disposed on the upper side of the first closing plate 21;
[0028] The second sealing component 3 includes:
[0029] A second closing plate 31 is rotatably arranged on the side of the floor drain housing 1, and the second closing plate 31 is inclined;
[0030] A third closing plate 32 is rotatably arranged on the side of the floor drain shell 1, the third closing plate 32 is tilted, and the third closing plate 32 is in contact with the lower end surface of the second closing plate 31;
[0031] The second sealing block 33 is rotatably connected to the second closing plate 31 and is disposed on the upper side of the second closing plate 31;
[0032] The third sealing block 34 is rotatably connected to the third closing plate 32 and is disposed on the upper side of the third closing plate 32 .
[0033] When there is no water accumulation, the first closing plate 21 closes the floor drain shell 1, and the first closing plate 21 maintains a balance with the first sealing block 22; the second closing plate 31 and the third closing plate 32 are closed, and the second closing plate 31 and the second sealing block 33 maintain a balance, and the third closing plate 32 and the third sealing block 34 maintain a balance.
[0034] Through the above technical solution, when the large-flow double-seal floor drain is draining, water and hair first pass through the cover plate 11. At this time, the hair is blocked by the cover plate 11, and the water continues to flow downward, first flowing to the first sealing component 2, first colliding with the first closing plate 21, and flowing downward along the inclination direction of the first closing plate 21. The water flow causes the first closing plate 21 and the first sealing block 22 to be unbalanced, so that the first closing plate 21 rotates, and the water flows downward from the first closing plate 21 and the floor drain shell 1 to the second sealing component 3; at this time, the second closing plate 31 and the second sealing block 33 are unbalanced, and the third closing plate 32 and the third sealing block 34 are unbalanced, so that the second closing plates 31 and the third closing plates 32 rotate, and the water flows downward from the second closing plate 31 and the third closing plate 32, enters the sewer pipe and is discharged. After the water is drained, the gravity of the first sealing block 22 causes the first closing plate 21 to rotate and reset, re-close the floor drain shell 1, and maintain balance; when the gravity of the second sealing block 33 and the third sealing block 34 is closed, the second closing plate 31 and the third closing plate 32 rotate and reset, re-close, and maintain balance.
[0035] This design uses a two-layer sealing structure for sealing, which has a good sealing effect and prevents water backflow. At the same time, it does not use a water seal layer to avoid the accumulation of impurities. It can maintain high-flow drainage for a long time without odor.
[0036] As an improved specific implementation, the rotation axis of the second closing plate 31 and the third closing plate 32 is perpendicular to the rotation axis of the first closing plate 21 .
[0037] Through the above technical solution, the structure enables the water left from the first closing plate 21 to quickly enter the gap between the second closing plate 31 and the third closing plate 32 and then be discharged, thereby increasing the drainage speed and avoiding water accumulation.
[0038] As an improved specific embodiment, a first magnet 41 is provided at the lower end of the first closing plate 21, and a first attracting magnet 13 is provided on the side of the floor drain shell 1. The position of the first magnet 41 corresponds to the position of the first attracting magnet 13, and the first magnet 41 and the first attracting magnet 13 are attracted to each other.
[0039] Through the above technical solution, the first closing plate 21 and the first sealing block 22 maintain a balance. When the floor drain shell 1 is closed, the first magnet 41 and the first attracting magnet 13 attract each other, which can be completely closed to further avoid backflow of water and odor.
[0040] As an improved specific implementation, a second magnet 42 is provided at the lower end of the second closing plate 31, and a third magnet 43 is provided at the lower end of the third closing plate 32. The second magnet 42 and the third magnet 43 correspond in position, and the second magnet 42 and the third magnet 43 attract each other.
[0041] Through the above technical solution, the second closing plate 31 and the second sealing block 33 are kept in balance, and the third closing plate 32 and the third sealing block 34 are kept in balance. When the floor drain shell 1 is closed, the second magnet 42 and the third magnet 43 attract each other, which can be completely closed to further avoid backflow of water and odor.
[0042] As an improved specific implementation, a second sealing strip 51 is provided at the lower end of the second closing plate 31 , and a third sealing strip 52 is provided at the lower end of the third closing plate 32 .
[0043] Through the above technical solution, when the second closing plate 31 and the third closing plate 32 are closed, the second sealing strip 51 and the third sealing strip 52 are in contact with each other, so the sealing effect is good, and water backflow and odor backflow are further avoided.
[0044] As an improved specific implementation, a drainage block 6 is provided on the lower end surface of the first closing plate 21. The drainage block 6 has two pieces and is symmetrically arranged with the contacting edge of the second closing plate 31 and the third closing plate 32 as the symmetry axis.
[0045] Through the above technical solution, the drainage block 6 has two pieces, which are symmetrically arranged with the contact surface of the second closed plate 31 and the third closed plate 32 as the symmetrical plane. When the first closed plate 21 is opened and rotated downward, the drainage block 6 contacts the second closed plate 31 and the third closed plate 32, and pushes the second closed plate 31 and the third closed plate 32 to rotate downward, so that the second closed plate 31 and the third closed plate 32 are opened for drainage. There is no need to wait for water to flow onto the second closed plate 31 and the third closed plate 32 and then rely on the gravity of water to open the second closed plate 31 and the third closed plate 32. Opening the second closed plate 31 and the third closed plate 32 in advance can drain water faster and improve drainage efficiency.
[0046] As an improved specific implementation, the lower end surface of the drainage block 6 is arc-shaped.
[0047] Through the above technical solution, the contact surface between the arc surface and the second closing plate 31 and the third closing plate 32 is smooth with low friction, and the arc surface can fit with the second closing plate 31 and the third closing plate 32 as they rotate, thereby improving stability during use.
[0048] As an improved specific implementation, the drainage block 6 is provided with a plurality of through holes 61 .
[0049] Through the above technical solution, the design of the through hole 61 reduces the weight of the drainage block 6, thereby reducing the weight of the first sealing block 22, thereby reducing the mass of the entire floor drain, reducing wear during use, extending the service life, and facilitating transportation.
[0050] The above is only a preferred embodiment of the present invention. 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.
