Detailed Description
The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention, and the present invention is further described with reference to the accompanying drawings and embodiments.
Example 1, see fig. 1-6: a magnetic repulsion type floor drain core comprises a floor drain body 1, a sealing cover 2 and a hinge structure 3, wherein a straight-through water outlet is formed in the lower portion of the floor drain body 1, and a silica gel sealing gasket 4 is arranged on the inner side face of the sealing cover 2.
A positioning surface 5 is arranged on one side of the water outlet, two mounting seats 6 and two fixed magnetic blocks 7 (see fig. 1 and 4) which are arranged at intervals are arranged on the positioning surface 5, and the fixed magnetic blocks 7 are embedded into the mounting seats 6 one by one.
The hinge structure 3 is a columnar structure, two ends of the hinge structure 3 are connected with one side of the sealing cover 2, the sealing cover 2 can form a seal for a water outlet in the moving direction of the sealing cover, a groove body used for hinging the hinge structure 3 is arranged on the positioning surface 5, the hinge structure 3 is hinged in the groove body, and the centers of the two fixed magnetic blocks 7 are positioned above the axis of the hinge structure 3; a first mounting seat 8 is arranged on the other side of the hinge structure 3, and a moving magnetic block 9 is embedded in the first mounting seat 8, wherein the moving magnetic block 9 corresponds to the two fixed magnetic blocks 7 and is distributed on the inner sides of the two fixed magnetic blocks 7; the magnetic poles of the movable magnetic block 9 and the fixed magnetic block 7 are arranged at the left end and the right end, the magnetic poles at the opposite ends of the movable magnetic block and the fixed magnetic block are the same and repel, and the movable magnetic block 9 and the fixed magnetic block 7 generate resetting force by utilizing the principle that the magnetic poles are the same and repel, so that the sealing cover 2 tightly seals the water outlet. And a cavity 10 which can meet the requirement of the first mounting seat 8 is also arranged on the positioning surface 5.
The positioning surface 5 is provided with a cover plate 11 which completely covers the movable and fixed magnetic block 7 and the movable magnetic block 9, and the lower end of the cover plate 11 is provided with a limiting part 12 which limits the opening angle of the sealing cover 2; the maximum opening angle of the sealing cap 2 is not more than 100 ° (see fig. 3); when the sealing cover 2 is opened to the maximum angle, the center of the movable magnetic block 9 is positioned on the right side of the central line of the fixed magnetic block 7 and the hinge structure 3 (see fig. 6), so that the direction of the repulsive force of the fixed magnetic block 7 acting on the movable magnetic block 9 is converted into the pushing force F1 for pushing the sealing cover 2 to rotate, the pushing force in the clockwise direction can ensure that the sealing cover 2 is effectively reset, and the repulsive force of the fixed magnetic block 7 acting on the movable magnetic block 9 in the sealing state of the sealing cover 2 is converted into the pushing force F2 for pushing the sealing.
This embodiment is too big in order to prevent sealed lid 2 opening angle and lead to sealed lid 2 to reset, has designed spacing portion 12 structure at the lower extreme of apron 11, prevents sealed lid 2 opening angle too big, enables sealed lid 2 simultaneously and opens the maximum angle for being no more than 100, makes it reach the biggest drainage effect. The cover plate 11 can cover the fixed magnetic block 7 and the movable magnetic block 9, and can prevent drainage water from corroding the fixed magnetic block 7 and the movable magnetic block 9.
The repulsive force F between the fixed magnetic block 7 and the movable magnetic block 9 is linearly increased from the sealing state to the opening to the maximum angle of the sealing cover 2, but the pushing force F converted from the repulsive force F & ltx sin & gt & ltc & gt & ltc & gt & ltc. This structure setting can guarantee to move the restoring force that produces between magnetic path 9, the fixed magnetic path 7 and can not open and increase along with the rotation of the relative pin joint of sealed lid 2, sealed lid 2 can open the at utmost when having guaranteed the drainage, does benefit to the drainage.
Example 2, see fig. 7 and 8: a magnetic-repellent floor drain core, which is different from the core of embodiment 1 in that: the magnetic poles at the opposite ends of the magnetic poles of the movable magnetic block 9 and the fixed magnetic block 7 are attracted to each other, and the movable magnetic block 9 and the fixed magnetic block 7 generate a resetting force by utilizing the principle that the magnetic poles are attracted to each other to enable the sealing cover 2 to tightly seal the water outlet. When the sealing cover 2 seals the water outlet, the center of the movable magnetic block 9 is positioned on the left side of the center line of the fixed magnetic block 7 and the hinge structure, the suction force F between the fixed magnetic block 7 and the movable magnetic block 9 pushes the sealing cover 2 to seal towards the water outlet, the thrust force F3 which pushes the sealing cover 2 to seal towards the water outlet is F sin which is equal to F, when the sealing cover 2 is opened to the maximum, the thrust force F4 which pushes the sealing cover 2 to seal towards the water outlet is F sin which is equal to F, and in the process from sealing to opening of the sealing cover 2, F linearly decreases and is linearly increased by being equal to F4, so that F3.
