The invention discloses a double odor-resistant drain core, and aims to solve a normally encountered odor resistance problem through water sealing odor resistance and hard sealing odor resistance. The drain core structurally comprises a water storage pipe which takes the shape of a U-shaped pipe, and is characterized in that the structure is a water collection pipe and a sealing cover in the water storage pipe. Water seal is formed between a part of water of the water storage pipe and the water collection pipe, so odor resistance can be performed under normal conditions, and the odor resistance effect of the water seal is superior; when a part of water of the water storage pipe is evaporated and the water seal cannot be formed between the part of water and the water collection pipe, the sealing cover can cover an annular stop block and forms hard sealing with the annular stop block, and an odor resistance function can also be achieved. Small objects can also be prevented from flowing away from a floor drain, and insects can also be prevented from climbing into a room from a sewer.
