The plurality of first convex rings 121 enhance the structural strength and stability, and limit the first sealing ring 126. The anti-disengagement ring 112 limits the first convex ring 121 from disengaging from below the upper core 11, avoids accidental separation of the upper core 11 and the adjusting core 12, and ensures the reliability and safety of the floor drain core during use. When the adjusting core 12 and the upper core 11 are assembled, the bottom end of the adjusting core 12 needs to be inserted into the top end of the upper core 11 for assembly.

[0046] With reference to Figure 4 and Figure 5The outer wall of the bottom end of the adjusting core 12 is provided with a protrusion 123, the inner wall of the top end of the lower core 13 is provided with an avoiding ring groove 132, a through groove 133 only for the protrusion 123 to pass through, and an arc groove 134 arranged in the circumferential direction, the upper and lower ends of the through groove 133 are respectively communicated with the middle part of the avoiding ring groove 132 and the arc groove 134, the protrusion 123 sequentially passes through the avoiding ring groove 132 and the through groove 133 to enter the arc groove 134, and abuts against the end wall of the arc groove 134.

[0047] With reference to Figure 4 and Figure 5 , the cooperation of the protrusion 123, the avoiding ring groove 132, the through groove 133 and the arc groove 134 realizes the quick connection and positioning between the adjusting core 12 and the lower core 13, and only needs to align the protrusion 123 with the through groove 133 and insert, and then rotate the adjusting core 12 to make the protrusion 123 enter the arc groove 134, so that the operation is simple, the connection is stable, and the installation efficiency is improved.

The booster plate 21 is hinged at the higher end of the water outlet 131, and the booster plate 21 is against the middle position of the bottom of the sealing plate 136.

[0055] With reference to Figure 4 , Figures 6-8 , the booster plate 21 and the elastic reset member are arranged. When the water flow stops, the elastic reset member drives the booster plate 21 against the bottom of the sealing plate 136, helping the sealing plate 136 to quickly reset and tightly seal the water outlet 131, preventing odors and pests in the sewer from entering the room. The booster plate 21 is against the middle position of the bottom of the sealing plate 136, making the sealing plate 136 more evenly stressed and having better sealing effect.

[0056] With reference to Figure 4 , Figures 6-8 , the lower core body 13 is hinged to one side of the sealing plate 136 and is provided with a mounting cavity 3. The mounting cavity 3 is provided with a side cover 31, which is detachably connected to the lower core body 13. The hinging shafts of the elastic reset member and the booster plate 21 are located in the side cover 31. The lower end of the side cover 31 extends a blocking part 311 for limiting the downward turning angle of the booster plate 21.

[0057] With reference to Figure 4 , Figures 6-8 , the mounting cavity 3 is used to accommodate the hinging shafts of the elastic reset member and the booster plate 21. The detachable connection of the side cover 31 facilitates the installation, debugging and maintenance of the internal components. The blocking part 311 limits the downward turning angle of the booster plate 21, ensuring that the booster plate 21 works within a suitable angle range and ensuring the normal opening and closing action and sealing effect of the sealing plate 136.

The elastic reset component includes a magnetic component 1 213 and a magnetic component 2 313. Both magnetic component 1 213 and magnetic component 2 313 are magnets. Magnetic component 1 213 is located at the drive end 211, and magnetic component 2 313 is located inside the side cover 31. Magnetic component 2 313 is located on the side of magnetic component 1 213 away from the water outlet 131. Magnetic component 1 213 and magnetic component 2 313 drive the assist plate 21 to reset through the repulsive force.

[0059] Reference Figure 4 , Figures 6-8 The auxiliary plate 21 is reset by using the repulsive force between magnetic component 213 and magnetic component 313. The structure is simpler and less prone to damage. The magnetic reset response is fast, which can help the sealing plate 136 reset more promptly and improve the odor and insect prevention performance of the floor drain.
