The invention relates to a zero-pollution squatting pan. When a person squats for excretion, bad smells emitted by defecation will be sucked into a sewer pipe of a toilet in a full-automatic manner when the bad smells are in an excreta groove, and therefore the person cannot smell the bad smells. Internal structures of the zero-pollution squatting pan comprise a water flushing defecation channel and a smell sucking and exhausting channel, wherein the smell sucking and exhausting channel is composed of a smell sucking channel, a draught fan chamber and a smell exhausting channel; the first section is the smell sucking channel, and smell sucking holes of the smell sucking channel are arranged above water flushing holes arranged on the water flushing defecation channel; the second section, namely the draught fan chamber, is arranged behind the smell sucking channel, and a draught fan and a one-way valve are successively installed in the draught fan chamber in the airflow direction in sequence; and the third section, namely the smell exhausting channel, is connected behind the draught fan chamber, the tail end of the smell exhausting channel extends into a defecation opening of the squatting pan, and the defecation bad smells discharged from the draught fan are exhausted into the sewer pipe of the toilet. A water flushing valve of the squatting pan is designed to be in a full-automatic type; starting and stopping of the draught fan are automatically controlled through an automatic switching power source; and starting and stopping of the water flushing valve are also automatically controlled through the automatic switching power source.
