[0026] Specifically, when the toilet is used, fresh air from the outside enters the through groove 4 through the slot 42 in the outer end of the through groove 4. The slot 42 is inclined upward from the outer side to the inner side, which ingeniously guides the air to enter while preventing rainwater, sewage and the like from entering the through groove 4. The filter screen two 41 in the inner end of the through groove 4 and the filter screen one 53 on the inner side of the slot 42 can filter the passing air to prevent dust, hair and the like from entering. Fresh air is stably conveyed into the inner part of the toilet main body 1 under the action of the fan 52 driven by the motor 51 in the ventilation assembly 5. The rotation of the fan 52 provides stable power for the air to enter, so that fresh air can continuously supplement the inside of the toilet.

[0027] The motor 51 in the ventilation assembly 5 at the two ends of the air exhaust cavity 17 drives the fan 52 to rotate to provide power for air exhaust. When the fan 52 rotates in the air exhaust cavity 17, the air in the air exhaust cavity 17 is exhausted from the inside of the toilet main body 1, so that a low-pressure area is formed in the air exhaust cavity 17. Under the action of the pressure difference, the odor in the toilet is rapidly sucked into the air exhaust cavity 17. Under the continuous operation of the fan 52, the odor in the air exhaust cavity 17 is exhausted to the outside of the toilet, and at the same time, the ventilation assembly 5 at the bottom continues to work to convey fresh air, so that the circulation process of air entering from the bottom and being exhausted from the top is maintained, the air in the toilet is continuously circulated, and thus the odor generated in the toilet can be completely exhausted from the toilet.

[0028] Embodiment 2

[0029] To reduce the odor exhausted and improve the continuous operation of the fan 52 when no one is present, please refer to Figures 1-5 On the basis of embodiment 1, ventilation holes 3 are formed in the bottoms of the two sides of the toilet main body 1, filter screens three 31 are fixedly installed on the outer sides of the ventilation holes 3, and insertion grooves 13 are installed on the inner sides of the ventilation holes 3.
