During use, the above patent can monitor the internal temperature of the fixed shell in real time by cooperating with the temperature sensor, the single-chip microcomputer and the hair dryer, and utilizing the operation of the temperature sensor. Once the temperature value is detected to exceed the set value, the temperature sensor will send a signal to the single-chip microcomputer, and the single-chip microcomputer can control the operation of the hair dryer in time. The hair dryer can blow air into the fixed shell, so that the voice interaction device can operate in a low-temperature environment and extend its service life.
