DETAILED DESCRIPTION
[0032] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.
[0033] See also Figures 1 to 8 The utility model discloses a floor drain core, the floor drain core 1 comprises a water inlet cover plate 11, a sealing cover plate 12 and a sliding connection mechanism 13, the water inlet cover plate 11 comprises a ring body 111 assembled on the floor drain housing 2 and a cross body 112 arranged in the ring body 111, the cross body 112 surrounds four fan-shaped water inlet holes 113 in the ring body 111; the sliding connection mechanism 13 comprises two sliding guide pillars 131 extending downward from the middle part of the cross body 112, and a sliding guide pillar 131 arranged in the middle part of the sealing cover plate 12. The sealing cover plate 12 has two sliding through holes 132 for the two sliding guide pillars 131 to pass through and a locking plate 133 fixed to the bottom ends of the two sliding guide pillars 131. The sealing cover plate 12 is provided with a first magnet 134 at a position between the two sliding through holes 132, and the locking plate 133 is provided with a second magnet 135 that magnetically repels the first magnet 134. The sealing cover plate 12 is pushed upward by the magnetic repulsion force of the first magnet 134 and the second magnet 135 to slide against the bottom surface of the water inlet cover plate 11 to seal the four fan-shaped water inlet holes 113.
[0034] The floor drain core 1 of the utility model is provided with a sealing cover plate 12 which can abut against the sealing water inlet cover plate 11, and the water inlet cover plate 11 and the sealing cover plate 12 are not fixedly connected together by a cylindrical ring wall. When draining water, the interval after the water inlet cover plate 11 and the sealing cover plate 12 are separated is a drainage space, the drainage space is large, and the drainage speed is fast; moreover, the floor drain core 1 does not need to be used in conjunction with the drainage hole of the floor drain shell 2, so that the versatility of the floor drain is better; when the floor drain core 1 drains water, the gravity of the water pushes the sealing cover plate 12 to move downward, opens the fan-shaped water inlet hole 113, and the water flows downward from the fan-shaped water inlet hole 113 and along the circumference of the sealing cover plate 12, and the floor drain core 1 drains water faster; when the floor drain core 1 does not drain water, the first magnet 134 and the second magnet 135 magnetically repel each other, push the sealing cover plate 12 to move upward and abut against the water inlet cover plate 11 to seal the fan-shaped water inlet hole 113, and the sealing and deodorizing effect of the floor drain core 1 is better.
[0035] The cross body 112 of the utility model has four support plates 114 connected to the ring body 111, and the bottom surface of each support plate 114 is provided with a guide protrusion 115, and the sealing cover plate 12 is provided with four through holes 121 for the guide protrusion 115 to be clamped. When draining water, the water can also be drained downward from the through holes 121, which increases the drainage space and the drainage speed; and it can prevent water from being retained on the sealing cover plate 12.
[0036] The guide protrusion 115 of the utility model has a first arcuate edge 1151 close to the ring body 111 and a second arcuate edge 1152 close to the center of the circle, and the through hole 121 has a third arcuate edge 1211 located outside the first arcuate edge 1151 and a fourth arcuate edge 1212 located outside the second arcuate edge 1152; and the first arcuate edge 1151, the second arcuate edge 1152, the third arcuate edge 1211 and the fourth arcuate edge 1212 are arranged concentrically with the ring body 111; the guide protrusion 115 can be stably clamped in the through hole 121, the sealing between the water inlet cover plate 11 and the sealing cover plate 12 is better, and the deodorizing effect is better.
[0037] The four sides of the through hole 121 of the utility model and the four sides of the guide protrusion 115 are arranged at intervals correspondingly, and the thickness of the guide protrusion 115 is less than the depth of the through hole 121; when the sealing cover plate 12 slides up and down, it is convenient for the guide protrusion 115 to enter and exit the through hole 121, and the sealing effect is better.
[0038] The two sliding guide pillars 131 of the utility model are symmetrically arranged arc-shaped guide pillars, and the circular ring where the sliding guide pillars 131 are located is concentrically arranged with the ring body 111; the sliding through hole 132 is an arc-shaped hole matched with the sliding guide pillar 131;.
[0039] The sliding guide column 131 of the utility model comprises a first section 1311 for guiding the sealing cover plate 12 to slide and a second section 1312 which is clamped with a locking plate 133. The thickness of the first section 1311 is greater than that of the second section 1312, and a step ring 1313 is formed at the connection between the first section 1311 and the second section 1312. The locking plate 133 is provided with a clamping hole 1331 for clamping and fixing the second section 1312. The top surface of the locking plate 133 abuts against the bottom of the step ring 1313. The locking plate 133 can limit the lowest position of the sealing cover plate 12 to slide downward, and the step ring 1313 can limit the sealing cover plate 12 to slide downward downward. The highest position of the locking plate 133 ensures that the magnetic repulsive force between the first magnet 134 and the second magnet 135 can push the sealing cover plate 12 to move upward and press against the bottom surface of the water inlet cover plate 11 to seal the fan-shaped water inlet 113; moreover, when the floor drain core 1 is draining water, when the sealing cover 12 is against the top of the locking plate 133, the maximum distance between the water inlet cover plate 11 and the sealing cover plate 12 is separated, the drainage space is maximized, and the drainage speed is fast; and the locking plate 133 can prevent the sealing cover plate 12 from falling off the sliding guide column 131, ensuring that the sealing cover plate 12 always slides up and down on the sliding guide column 131.
[0040] The bottom surface of the water inlet cover plate 11 of the utility model is provided with an annular groove 116 for the sealing cover plate 12 to be clamped, so that the sealing effect between the water inlet cover plate 11 and the sealing cover plate 12 is better.

[0042] The floor drain shell 2 of the utility model has a rectangular outer frame 22, and the assembly step ring 21 is arranged at the center position of the rectangular outer frame 22; when the floor drain core is damaged and replaced, the rectangular outer frame 22 is fixed to the original floor drain shell 2, and the floor drain core of the application can be replaced, which makes maintenance and replacement more convenient and quick.
[0043] The floor drain housing 2 of the present invention is also movably covered with a filter screen above the water inlet cover plate 11; the filter screen can filter debris to avoid clogging the fan-shaped water inlet 113, making drainage smoother.
[0044] The above embodiments and drawings do not limit the product form and style of the utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the utility model.
