The invention relates to an intelligent towel drying device. The device comprises an information collection system, a voltage comparator, a single-chip microcomputer and a drying device. The information collection system realizes the collection of the information content by using an infrared ray sensor. The voltage comparator is used for comparing the information content collected by the information collection system with a reference voltage. The single-chip microcomputer controls the number and the lighting time of drying lamps of the drying device according to the output of the voltage comparator. According to the invention, the towel can be dried in the first time, the risk in sanitation is reduced greatly, and the peculiar smell is avoided.
