At present, most of floor drains used in families are still common cast iron floor drains, the upper ends of the floor drains are provided with water inlets, and the lower ends of the floor drains are provided with water outlets; the end surface of the upper end of the floor drain is generally flush with the ground (or slightly lower than the ground); the lower end of the floor drain is communicated with a sewer.

The structure of the sewer is closed, so that sewage gas is easy to generate, the sewage gas comprises toxic, harmful, inflammable and explosive gases such as methane, hydrogen sulfide and the like, and therefore the lower end of the floor drain is generally provided with an S-shaped water seal pipeline, so that the gas of the sewer can be prevented from entering a room in a water seal mode. However, water in the water seal pipeline is easy to evaporate, and once water is not stored in the water seal pipeline, sewage gas in a sewer can enter the ground (indoor or outdoor) through the floor drain outlet. The sewage gas can not only poison people, but also form combustible gas after being mixed with air, and the explosion can be generated when the sewage gas meets open fire, thereby easily causing serious safety accidents.

However, the existing intelligent floor drain has the following problems when in use: on one hand, in the detection mode, when the sewage gas is detected to flow back, a large amount of sewage gas flows out of the ground (indoor or outdoor), so that serious air pollution and potential safety hazards are caused, the real-time performance of the sewage gas detection is low, and the detection effect on the sewage gas is poor; on the other hand, can mix with the air after sewage gas flows out the floor drain for including a large amount of air and a small amount of sewage gas in the gas that the air inlet fan sent into, make that the detection precision to sewage gas is low, lead to equally not good to sewage gas's detection effect.
