The invention provides a humidifier and an atomizer component for the humidifier. The atomizer component for the humidifier comprises an oscillator plate, a radiating plate which is connected with the oscillator plate, a control plate which is connected with the radiating plate and is provided with a control circuit, and a thermal fuse link which is connected with the control circuit in series and is connected with the control plate. According to the atomizer component for the humidifier provided by the invention, under the condition that the atomizer component still works when water is in shortage, a temperature of the oscillator plate is sharply risen, so that the temperature of the control plate is also sharply risen; the thermal fuse link is connected with the control plate, so that the temperature of the thermal fuse link is also sharply risen; when the temperature of the control plate reaches an operating temperature of the thermal fuse link, the thermal fuse link is disconnected; the thermal fuse link is connected with the control circuit in series, and the control circuit is also disconnected correspondingly, so that the humidifier stops working, a safety accident of the humidifier due to an excessively high temperature of the control plate is avoided, and the potential safety hazards of the humidifier due to the excessively high temperature of the control plate are eliminated.
