Intelligent false alarm preventing infrared detector

The invention relates to an intelligent false alarm preventing infrared detector, which comprises an infrared sensor and a sensor heat-preserving protective part, wherein the infrared sensor is embedded in the sensor heat-preserving protective part; and the head part of the infrared sensor is exposed. Better, the intelligent false alarm preventing infrared sensor also comprises a circuit board. The sensor heat-preserving protective part comprises an upper heat-preserving protective pad and a lower heat-preserving protective pad; the infrared sensor is arranged in the circuit board and is electrically connected with the circuit board; the lower heat-preserving protective pad is positioned on the lower surface of the circuit board to cover the infrared sensor, while the upper heat-preserving protective pad is positioned around the head part of the infrared sensor; the upper and lower heat-preserving protective pads can be sponge pads; and the upper heat-preserving protective pad can be further pressed against a
