[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0030] like Figures 1-9As shown, an odor-proof and clog-proof floor drain includes a drain grate 27, a drain body 28, and a drain core 29. The drain grate 27 is installed on the drain body 28, and the drain core 29 is located below the drain body 28. The drain core 29 and the drain body 28 are connected. A button 16 is provided on the drain grate 27, and an odor-proof structure is provided at the bottom of the drain core 29. The button 16 is connected to the drain core 29 through a self-locking structure. The upper part of the drain body 28 is flush with the ground plane, allowing water to flow into the drain. The drain grate 27 is used to filter foreign objects such as hair, and the drain core 29 is used for drainage and odor prevention. The self-locking structure can control the opening and closing of the drain.

[0031] The odor-proof structure includes a drain cover 14 and a sealing magnet 15. The drain cover 14 and the drain core 29 are movably connected at the bottom. The sealing magnet 15 includes two magnets with opposite magnetic poles. The sealing magnet 15 is located on the other end of the drain cover 14. The upper end of the drain cover 14 is provided with a rotating shaft 13 that is hinged to the drain core. When water flows in, under the action of water pressure or gravity, the sealing magnet 15 on the drain cover 14 at the bottom of the drain core 29 is pushed open, the drain cover 14 opens, and water flows into the sewer pipe. When there is no water, the sealing magnet 15 on the drain cover 14 at the bottom of the drain core 29 is attracted, the drain cover 14 closes, and the drain cover 14 has a large drainage cross section and a high drainage rate.

[0032] The upper surface of the drain grate 27 is provided with horizontal strip holes 1. The lower part of the drain grate 27 is a hollow cylinder 5. The outer side of the hollow cylinder 5 is provided with a first spiral nylon filament 4, and the inner layer of the drain body 28 is provided with a second spiral nylon filament 9. The horizontal strip holes 1 are circumferentially distributed between the button 16 and the edge of the drain grate 27, serving as a primary filter that can filter out most foreign objects such as hair. The first spiral nylon filament 4 is circumferentially distributed on the outer side of the hollow cylinder 5, and the second spiral nylon filament 9 is circumferentially distributed on the inner layer of the drain body 28 and can be arranged in multiple layers. The first spiral nylon filament 4 and the second spiral nylon filament 9 serve as a secondary filter that can effectively hook hair, facilitating subsequent processing.

[0033] The upper edge of the drain grate 27 is provided with a sliding hook 3, and the upper layer of the drain body 28 is provided with an annular sliding groove 6. The annular sliding groove 6 is provided with a sliding groove hole 7 that cooperates with the sliding hook 3. The two sliding hooks 3 are arranged circumferentially opposite each other, and the sliding groove hole 7 corresponds to the sliding hook 3, so that the sliding hook 3 can be rotated to align with the sliding groove hole 7, and the drain grate 27 can be installed and removed. Rotating the sliding hook 3 to misalign with the sliding groove hole 7 can lock the drain grate 27. The two are designed to be rotating, making the installation and removal process convenient and quick.

[0034] The lower part of the drain body 28 is a cylinder with an internal thread 8 on the inner layer of the cylinder. The upper part of the surface of the drain core 29 has an external thread 12. The external thread 12 of the drain core 29 mates with the internal thread 8 of the cylinder, making it easy to screw the drain core 29 to the drain body 28.

[0035] As shown in Figure 4 and Figure 5As shown, the upper part of the inner layer of the drain core 29 is provided with a clamp 10, which is laterally opposite to the drain core 29. The clamp 10 is provided with a fan-shaped hole and a circular hole. The middle part of the inner layer of the drain core 29 is provided with a base 11, which is longitudinally opposite to the fan-shaped hole. The fan-shaped hole is designed to fit the shape of the hollow cylinder at the bottom of the button 16, which is convenient for processing. The fan-shaped hole is used to fix the upper end of the self-locking strip 24. The upper end of the self-locking strip 24 can be inserted into the fan-shaped hole of the clamp 10. The circular hole is designed to reduce the friction of the rebound rod 22 and to limit the rebound rod 22 to only move up and down, thus playing a guiding role. The rebound rod 22 can be inserted into the circular hole of the clamp 10. The lower end of the self-locking strip 24 can be supported on the fan-shaped base 11 to fix the lower end of the self-locking strip 24.

[0036] like Figure 5 and Figure 6 As shown, the drain grate 27 has a button mounting hole 2 on its upper part, and a button 16 is installed in the button mounting hole 2. The upper part of the button 16 is a solid cylinder, and the lower part of the button 16 is a hollow cylinder. The upper part of the button 16 has a threaded hole 19. The self-locking structure includes a spring rod 22 installed in the threaded hole 19. A baffle 18 is provided on the lower outer side of the button 16. One end of the spring rod 22 has a spring rod external thread 21 that is screwed to the button 16, which can realize the pressing and rebound of the button 16. The baffle 18 is used to limit the rebound height of the button 16. The button 16 has a groove 20 to save processing materials.

[0037] As shown in Figure 4- Figure 7 As shown, the self-locking structure also includes a self-locking slider 23, a self-locking strip 24, and a self-locking groove 25. The rebound rod 22 passes through the annular hole. The self-locking slider 23 is located at the lower part of the rebound rod 22 that passes through the annular hole. The self-locking strip 24 is provided with a self-locking groove 25 that cooperates with the self-locking slider 23. The self-locking strip 24 is provided with an installation groove. The self-locking strip 24 is engaged with the fan-shaped annular hole through the installation groove. The lower end of the self-locking strip 24 is supported on the base 11. The rebound rod 22 slides up and down in the annular hole to realize the pressing and rebound of the button 16. The self-locking strip 24 is restricted and fixed by the fan-shaped annular hole and the base 11. The self-locking structure is controlled by the button 16. Stepping on the button 16 can control the opening and closing of the floor drain.

[0038] The self-locking slide 25 is a heart-shaped structure. The upper apex and the middle of the lower part of the self-locking slide 25 are provided with concave spaces. One end of the lower part of the self-locking slide 25 is provided with a step that gradually decreases, and the other end of the lower part of the self-locking slide 25 is provided with a gradually rising slope. The self-locking slide head 23 moves along a trajectory in the self-locking slide 25 and can stay in the self-locking slide 25 and make unidirectional cyclic movements.

[0039] A button magnet 17 is provided on the inner side of the lower part of the button 16, and a self-locking bar magnet 26 with the same magnetic pole as the button magnet 17 is provided on the upper part of the self-locking bar 24. The button magnet 17 and the self-locking bar magnet 26 are of the same pole and generate a repulsive force. Since the self-locking bar 24 is restricted and fixed, the button 16 is subjected to an upward repulsive force, which ensures that the button 16 can protrude above the ground plane.

[0040] like Figure 1 As shown in Figure 4, during drainage, water flows into the drain body 28 through the horizontal holes 1 on the drain grate 27. Most foreign objects such as hair are blocked by the horizontal holes 1, serving as primary filtration. The water flows into the drain body 28, which has a large debris filtration area and drainage area, and does not occupy bathroom space, reducing clogging and facilitating drainage. The first spiral nylon filament 4 and the second spiral nylon filament 9 can hook and entangle foreign objects such as hair, serving as secondary filtration. The water continues to flow into the drain core 29, where it is further filtered by water pressure or gravity. When the drain cover 14 at the bottom of the drain core 29 is opened by the sealing magnet 15, the drain cover 14 opens, and water flows into the sewer pipe. When there is no water, the sealing magnet 15 on the drain cover 14 at the bottom of the drain core 29 closes, and the drain cover 14 closes. The double drain cover 14 magnetic design increases the drainage cross section and greatly improves the drainage speed. The sealing magnet 15 is sealed and protected, making it less susceptible to water corrosion and deformation. Its service life can reach 5-10 years. It can effectively prevent the spread of odors and insects in the sewer pipe and prevent backflow.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, when it is necessary to remove the drain grate 27, rotate the grate until the sliding hook 3 on the drain grate 27 is aligned with the sliding hole 7 on the surface of the drain body 28, and the arrow on the grate is aligned with the arrow on the surface of the drain body 28, then the grate can be removed; when installing the drain grate 27, after aligning the arrow on the grate with the arrow on the surface of the drain body 28, lower the grate, and rotate it until the arrow is misaligned to lock the grate.

[0042] like Figure 5 , Figure 7As shown, when the drain is turned on, the self-locking strip magnet 26 and the button magnet 17 are opposite each other with the same poles. According to the principle that like poles of magnets repel each other, the button 16 is always subjected to an upward repulsive force. At the same time, the baffle 18 on the lower outer side of the button 16 abuts against the lower cylinder of the drain grate 27, so that the button 16 is subjected to a downward pressure. The button 16 is relatively stationary due to the balance of forces. When the drain needs to be turned off, the button 16 is stepped on. The button 16 drives the rebound rod 22 to move downward. The self-locking slider 23 at the lower end of the rebound rod 22 slides down the self-locking groove 25 on the self-locking strip 24 and is stuck at point c. At this time, the button drops 20mm and the bottom of the button 16 just contacts the drain. At the top of core 29, button 16 is 22mm high, and hollow cylinder 5 at the bottom of the grate is 10mm high. After descending, button 16 and hollow cylinder 5 together form a 30mm high cylinder to block the water flow, closing the drain and stopping the flow of water. When the drain needs to be turned on, step on button 16 on the ground surface. Button 16 drives the rebound rod 22 to move downward. The self-locking slider 23 at the bottom of the rebound rod 22 slides down the self-locking groove 25 on the self-locking strip 24. When it reaches the raised slope at ef, the repulsive force of the self-locking strip magnet 26 on the button magnet 17 drives the self-locking slider 23 to move upward. When it reaches the top of the self-locking groove 25, button 16 resets, and the drain turns on.

[0043] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
