[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. The quality and performance of the floor drain directly affects the quality of indoor air and plays a very important role in odor control in the bathroom.

[0003] Therefore, the floor drain should have a certain anti-odor function, but the existing anti-odor structure of the floor drain is relatively complex, easy to damage, and has a high cost of use. After long-term use, the anti-odor resetting parts in the floor drain do not return in time or the sealing after returning is not enough, which leads to a gradual decrease in the anti-odor performance, causing adverse effects on indoor air and polluting the indoor air environment. Therefore, it is very necessary to improve the anti-odor structure in the existing floor drain. Summary of the invention

[0006] In the above-mentioned floor drain with better odor-proof sealing, the sealing ring is provided with an auxiliary sealing groove, and when there is no drainage gravity, the auxiliary sealing groove corresponds to the edge of the drainage hole at the bottom of the base.

[0007] In the above-mentioned floor drain with better odor-proof sealing, a fixing groove is arranged on the sealing ring, and a fixing boss cooperating with the fixing groove is arranged on the odor-proof rotating plate.

[0008] In the above-mentioned floor drain with better odor-proof sealing, an upper mounting groove for mounting an upper magnetic block is provided on the bottom of the base.

[0009] In the above-mentioned floor drain with better odor-proof sealing, the end of the odor-proof rotating plate is provided with a lower mounting groove for mounting a lower magnetic block.

[0010] In the above-mentioned floor drain with better odor-proof sealing, a filter installation groove is provided in the base, and an installation step is formed.

[0011] By adopting the above technical solution, the utility model has the following beneficial effects:

[0012] The utility model provides a closing structure that can generate an attractive force between the base and the deodorizing rotating plate. In the case of no drainage, the attractive force between the two is utilized to quickly rotate the deodorizing rotating plate to close the drainage hole on the base. At the same time, a unique sealing ring structure is provided on the deodorizing rotating plate. When in a closed state, the sealing ring forms an elastic seal with the edge of the drainage hole of the base under the action of the deodorizing baffle plate, thereby improving the sealing performance of the drainage hole in the closed state. The deodorizing rotating plate rotates and resets in time to cooperate with the elastic seal of the sealing ring, thereby better preventing sewer odor from rising up and achieving a better deodorizing sealing effect.
