[0030] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figure 1 and Figure 2 One embodiment of this utility model provides an easy-to-disassemble and maintain floor drain, including: a floor drain base 10, a cover 20, a handle 30, and a snap-on floor drain core 40;

[0031] The drain base 10 is provided with a flow guiding cavity 11 and a drain hole 12. The drain hole 12 is arranged at the bottom of the flow guiding cavity 11, and the top of the flow guiding cavity 11 is provided with an opening 13. The cover 20 is provided at the opening 13. The cover 20 is provided with a lifting through hole 21 and a filter assembly 22. The filter assembly 22 is connected to the flow guiding cavity 11. The handle 30 is movably inserted through the lifting through hole 21. Part of the handle 30 is arranged at the top of the cover 20. The handle 30 can descend along the lifting through hole 21 under its own weight. The snap-on drain core 40 is provided at the bottom of the drain base 10 and is connected to the drain hole 12.

[0032] Traditional floor drains are screwed onto the drain base 10 with threads, which makes disassembly inconvenient. Therefore, please refer to... Figure 3 and Figure 4 In this utility model, the snap-on drain core 40, which is easy to assemble and disassemble quickly, simplifies the assembly and disassembly process, making it convenient for users to operate. The drain base 10 is provided with multiple inclined claws 16 arranged around the drain hole 12. The side of the snap-on drain core 40 is provided with a support ring 41 and multiple protruding locking points 42. The support rings 41 are arranged around the snap-on drain core 40, and a space is formed between adjacent support rings 41 for the inclined claws 16 to pass through. The multiple protruding locking points 42 are evenly arranged around the snap-on drain core 40 and are located below the support rings 41. A limiting space is formed between the protruding locking points 42 and the support rings 41. The inclined claws 16 extend into the limiting space and are supported at the bottom of the support rings 41. When installing the snap-on drain core 40, align the protruding locking point 42 with the space between the two adjacent inclined claws 16, and then insert the snap-on drain core 40 into the drain hole 12, so that the protruding locking point 42 passes through the two adjacent inclined claws 16 and reaches the bottom of the inclined claws 16, and the bottom of the support ring 41 abuts against the top of the inclined claws 16. Then rotate the entire snap-on drain core 40 relative to the drain hole 12, so that the protruding locking point 42 is rotated to the bottom of the inclined claws 16. At this time, the inclined claws 16 and the protruding locking point 42 are in a limiting engagement, so that the snap-on drain core 40 cannot move upward relative to the drain hole 12, and the inclined claws 16 are supported at the bottom of the support ring 41, so that the snap-on drain core 40 cannot move downward relative to the drain hole 12. Therefore, the snap-on drain core 40 can be quickly fixed by rotating it at a certain angle, which is convenient to operate. The rotation angle of the snap-on drain core 40 can be designed according to the actual number and length of the inclined claws 16 and protruding locking points 42, and no specific angle is limited here.

[0033] In one embodiment of this utility model, the easy-to-disassemble and maintain floor drain is used such that the floor drain base 10 is installed on the ground, while the snap-on floor drain core 40 is connected to the drain pipe. After the water reaches the cover 20, it enters the guide chamber 11 from the filter screen assembly 22, then flows into the snap-on floor drain core 40, and finally enters the sewer. The structure of the snap-on floor drain core 40 can be designed according to actual needs. For example, in this embodiment, the snap-on floor drain core 40 is an odor-proof snap-on floor drain core 40. An odor-proof cover is rotatably installed at the bottom of the snap-on floor drain core 40, thereby blocking the odor from the sewer from passing through the snap-on floor drain core 40. The structural design of the odor-proof cover is a technology known to those skilled in the art and will not be described in detail here.

[0034] Please see Figure 5 and Figure 6 In some optional embodiments, a first limiting slope 43 is formed at the top of the protruding locking point 42. The first limiting slope 43 gradually extends upward in a preset rotation direction around the snap-on drain core 40. A second limiting slope 17 is formed at the bottom of the claw 16. The second limiting slope 17 matches the first limiting slope 43. The claw 16 extends into the limiting space accordingly. When installing the snap-on drain core 40, after the protruding locking point 42 passes through two adjacent inclined claws 16 and reaches below the inclined claws 16, the bottom of the support ring 41 abuts against the top of the inclined claws 16. At this time, the snap-on drain core 40 needs to be rotated so that the protruding locking point 42 reaches the bottom of the inclined claws 16. When rotating the snap-on drain core 40, the distance between the second limiting inclined surface 17 and the bottom of the support ring 41 gradually decreases in the rotation direction of the snap-on drain core 40. Therefore, it is beneficial to guide the inclined claws 16 into the space between the support ring 41 and the protruding locking point 42. Moreover, after the first limiting inclined surface 43 and the second limiting inclined surface 17 are in contact, the user will not be able to continue rotating the snap-on drain core 40. At this time, it is equivalent to prompting the user that the snap-on drain core 40 has been installed.

[0035] The handle 30 of this utility model's easy-to-disassemble and maintain floor drain can automatically descend under gravity when not in use. When needed, the cover 20 can be lifted directly by the handle 30, making operation convenient and not affecting the user's daily walking. In some optional embodiments, after the handle 30 descends along the lifting through hole 21 under its own gravity, the top of the handle 30 is roughly flush with the top of the cover 20, and the handle 30 protrudes slightly from the cover 20, so that the handle 30 can be pulled up directly when needed. To facilitate the user in pulling up the handle 30, a certain gap is formed between the side of the handle 30 and the cover 20, making it easy for the user to grasp the handle 30. Alternatively, in some other embodiments, the cover 20 is provided with a relatively flat concave surface, so that the handle 30 can be hidden in the concave surface after descending and will not protrude from the cover 20.

[0036] Furthermore, the cover 20 is equipped with a filter screen assembly 22, which can be lifted directly when the cover is lifted. The claw-shaped filter screen assembly 22 has a large water flow area, resulting in fast water flow and less clogging, thus reducing the frequency of cleaning. The snap-on drain core 40 is easy to install and remove, requiring only a slight rotation.

[0037] Please see Figure 7 In some optional embodiments, the handle 30 includes a mushroom head 31, a lifting rod 32, and a limiting end 33 connected in sequence. The mushroom head 31 is positioned above the cover 20, the lifting rod 32 is movably inserted through the lifting through hole 21, and the limiting end 33 is positioned below the cover 20. When the handle 30 is lifted, the lifting rod 32 moves upward until the limiting end 33 abuts against the bottom of the cover 20, and then the handle 30 can drive the cover 20 to rise. Since the lifting rod 32 can extend partially upwards from the cover 20, it is convenient for the user to reach around to the bottom of the mushroom head 31 and grasp the entire mushroom head 31, avoiding the situation where the distance between the cover 20 and the mushroom head 31 is too close to allow for continuous grasping of the mushroom head 31. When the cover 20 is lowered, based on gravity, the lifting rod 32 descends along the lifting through hole 21 until the mushroom head 31 abuts against the top of the cover 20.

[0038] Please see Figure 8 and Figure 9 In some optional embodiments, the filter assembly 22 includes a plurality of filter claws 23, which are arranged in a preset direction and filter holes are formed between adjacent filter claws 23. The claw-shaped filter assembly 22 has a relatively large water flow area, which makes the water flow fast and less prone to clogging, thus reducing the number of cleaning times.

[0039] In some optional embodiments, the flow guiding cavity 11 extends along a preset direction, and multiple filter claws 23 are evenly arranged on both sides of the cover 20 in the preset direction. Filter claws 23 are arranged on both sides of the cover 20, and water can pass through both sides of the cover 20, which helps to increase the water flow area.

[0040] In some optional embodiments, the filter claw 23 includes a vertical portion 24 and an intercepting portion 25. The vertical portion 24 is connected to the faceplate 20, and the intercepting portion 25 is connected to the bottom of the vertical portion 24. A first filter hole 26 is formed between the vertical portions 24 of adjacent filter claws 23, and a second filter hole 27 is formed between the intercepting portions 25 of adjacent filter claws 23. Since the position of the intercepting portion 25 is lower than that of the vertical portion 24, and the first filter hole 26 is also lower than that of the second filter hole 27, when debris accumulates at the intercepting portion 25, the water passage area of ​​the first filter hole 26 may be reduced or even blocked. At this time, the water flow can pass through the second filter hole 27, thereby avoiding the situation where water cannot pass through due to the interception of debris, which is conducive to maintaining rapid water passage and avoiding blockage.

[0041] In some alternative embodiments, a flange 14 is provided at the edge of the opening 13, and a through groove 15 is formed between the flange 14 and the side of the cover 20. The through groove 15 is connected to the filter screen assembly 22. The flange 14 helps to improve the structural strength of the drain base 10 and improve its aesthetics. Water flows through the through groove 15 and then through the filter screen assembly 22, and then reaches the guide cavity 11.

[0042] In some alternative implementations, the snap-on drain core 40 is detachably connected to the drain base 10. Since the snap-on drain core 40 is a consumable part, it needs to be replaced or cleaned frequently to ensure its functionality. Therefore, the detachable design facilitates replacement.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
