[0036] This embodiment is basically as shown in the attached Figure 1 -Attached Fig. 9 As shown:
[0037] A same-layer double odor-proof floor drain comprises a floor drain seat 100 and a drainage pipe 200. A floor drain core 110 is installed on the floor drain seat 100. The floor drain core 110 comprises a cylinder 111 which passes through from top to bottom. A valve plate 112 is movably installed on the cylinder 111. When the valve plate 112 is in a natural state, the valve plate 112 is in a closed state. Specifically, when the valve plate 112 is in a natural state, the valve plate 112 is in a closed state, that is, the valve plate 112 blocks the lower end of the cylinder 111, so as to achieve the purpose of odor and insect prevention, that is, when no sewage is discharged, the valve plate 112 is in a closed state. When sewage is discharged, the valve plate 112 is gradually opened under the action of the water flow to drain the water, thereby preventing the odor and insects from overflowing or crawling out in reverse.
[0038] It should be noted that the dynamic sealing connection between the valve plate 112 and the cylinder 111 is a prior art. For example, components such as springs or magnets can be used to provide external forces for maintaining dynamic sealing. The detailed structure and principle will not be described here.
[0039] To achieve the drainage function, in the above solution, the drainage pipe 200 has a drainage port 201; specifically, there are two drainage ports 201 on the drainage pipe 200, which is convenient for connecting pipelines according to needs.
[0040] In order to further improve the odor prevention and achieve the purpose of double odor prevention, in this embodiment, a water seal 120 is connected between the floor drain seat 100 and the drainage pipe 200. Specifically, the water seal 120 includes a water inlet section 121 and a water outlet section 122, and the valve plate 112 is located in the water inlet section 121; one end of the water inlet section 121 extends to the inside of the water outlet section 122, and a water outlet cavity 123 is formed between the water inlet section 121 and the water outlet section 122, and the water outlet cavity 123 is connected to the drain port 201; a connecting tube 300 is installed between the floor drain seat 100 and the drainage pipe 200. Under the action of the water seal 120, in a specific use environment, the lower end of the water inlet section 121 is submerged by accumulated water, thereby preventing the odor from being directed upward into the room.
[0041] Furthermore, a filter cover 130 is installed on the floor drain seat 100 , and a plurality of drainage holes 131 are opened on the filter cover 130 . The sizes of the plurality of drainage holes 131 gradually increase from the center of the filter cover 130 to the edge of the filter cover 130 .
[0042] The floor drain seat 100 and the floor drain core 110 jointly support a filter 140, and the filter 140 has a plurality of drainage grooves 141. Specifically, the outer edge of the filter 140 is supported on the inner wall of the floor drain seat 100, and the lower part of the filter 140 abuts against the floor drain core 110.
[0043] Specifically, in the above solution, the filter 140 has a plurality of limiting feet 142, the lower ends of the plurality of limiting feet 142 are located in the cylinder 111, and part of the side walls of the limiting feet 142 are close to the inner wall of the cylinder 111. Preferably, in this embodiment, the number of the limiting feet 142 is four.
[0044] The side wall of the cylinder 111 can be detachably mounted on the water inlet section 121 , thereby facilitating the installation and disassembly of the floor drain core 110 .
[0045] Furthermore, a first external thread section 113 is provided on the outer wall of the cylinder 111 , and a first internal thread section 124 is provided on the inner wall of the water inlet section 121 . The first internal thread section 124 is matched with the first external thread section 113 .
[0046] The upper end of the water inlet section 121 is connected with a connector 150 , and the connector 150 is supported on the floor drain seat 100 ; the end edge of the cylinder 111 is supported on the connector 150 , and a fastener 160 is threadedly connected to the water inlet section 121 .
[0047] Specifically, the outer wall of the water inlet section 121 is provided with a second external thread section 125 , and the fastener 160 is provided with a second internal thread section 161 , and the second internal thread section 161 is matched with the second external thread section 125 .

[0050] In a specific installation or layout environment, the installation height or installation space of the floor drain is different. The connecting tube 300 in the above scheme needs to adjust the relative height according to the actual situation to adapt to the preset position of the installation environment. Since the connecting tube 300 has an installation groove 301, a tool can be used to saw or cut the connecting tube 300 along the position of the installation groove 301, thereby adjusting the height of the connecting tube 300 to meet the requirement of adjusting the overall height of the floor drain.
[0051] Furthermore, the water inlet section 121 has a plurality of grooves 126, and tools can be used to saw or cut the water inlet section 121 along the positions of the grooves 126, thereby flexibly adjusting the size of the lower end of the water inlet section 121 extending to the inner side of the water outlet section 122, that is, adjusting the height of the water inlet section 121 to meet the requirements of adjusting the overall installation height of the floor drain.
