Air purifier adopting liquid filtering medium

The utility model belongs to the technical field of air purification, and particularly discloses an air purifier adopting a liquid filtering medium, which comprises a container, an air inlet, an air inlet device and a communicating pipeline, the air inlet is communicated with the air inlet device, the air inlet device pumps air out of the communicating pipeline from the air inlet, and liquid is arranged in the container. One end of the communicating pipeline extends into the liquid, gas in the communicating pipeline enters the liquid, and substances in the gas are absorbed by the liquid and then discharged. Gas can be pumped into the connecting pipeline through the fan, the gas in the connecting pipeline is discharged to the gas spraying plate, the gas in the gas spraying plate is discharged into the liquid through the gas spraying holes, and substances in the gas can be absorbed (such as dissolution or chemical reaction) by the liquid and then discharged, so that the gas can be purified; and the cost can be
