The utility model belongs to the technical field of temperature detection. The intelligent temperature detection device comprises a temperature sensor, the problems that an existing temperature detection device stops working after power failure, and a temperature sensor cannot be well protected are solved. The device comprises a shell, the shell is divided into a bottom shell and a top shell, meshes penetrate through the top shell, a top cover is arranged on the bottom shell, a supporting frame is vertically arranged at the upper end of the top cover, a temperature sensor is fixed to the top end of the supporting frame, and the top cover is covered with the top shell; a signal receiving module, a signal processing module, a signal sending module and an electricity storage box are arrangedin the bottom shell, and the electricity inlet socket and the electricity storage box are electrically connected with the signal receiving module, the signal processing module, the signal sending module and the display screen. When power is off, the electricity storage box can provide electric energy for the device, and the temperature can be detected around the clock; and the meshes uniformly arranged on the top shell in the penetrating manner can prevent dust from contacting with the temperature sensor, so that more accurate detection data is ensured.
