As shown in fig. 6, in the second embodiment of the present invention, the bracket 120 is disposed on the sidewall of the through hole 110, i.e., the sliding hole 130 is disposed at one side of the through hole 110. More be favorable to reducing the pipe resistance through setting up sliding hole 130 at the side, and sliding hole 130 sets to non-circular, and corresponding movable rod 200 is along with the shape design, and movable rod 200 will not the free rotation and just slide from top to bottom, more is favorable to sealed lid 300 to aim at the body and seals deodorant. The elastic member 600 is a pair of magnets, and is characterized in that two magnets are oppositely arranged at the same level, one of the magnets is fixedly arranged on the movable rod 200, the other magnet is fixedly arranged on the sliding hole 130, and the effect of lifting the sealing cover 300 upwards is realized by utilizing the principle that the magnets repel at the same level.
Introduction of the working principle:
In a non-water state, as shown in fig. 4, the sealing cover 300 is pressed against the lower end of the floor drain body 100 under the action of the upward pulling of the movable rod 200 to form a seal, and at this time, the sealing cover can prevent odor and backflow;
In the water passing state, as shown in fig. 5, the sealing cover 300 moves downward under the impact of water flow and deflects, and the center of gravity also deflects, and at this time, the cross-sectional area of water flow S1= cross-sectional area of sewer pipe-cross-sectional area of the sealing cover 300 in the thickness direction, the cross-sectional area is small, and S1 is much smaller than S2 compared to the cross-sectional area of water flow S2= cross-sectional area of sewer pipe-cross-sectional area of the sealing cover 300 in the entire plane in fig. 8, and therefore the flow rate is also larger;
After the water flow stops, the sealing cover 300 is in a horizontal state due to the steering force generated by the deflection gravity center of the sealing cover, so that the sealing cover 300 can be conveniently and smoothly reset and cannot be blocked by the bottom end of the floor drain body 100.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
