Abstract:
The present invention relates to the technical field of hair care, and in particular relates to a heater and a hair care device. The heater comprises a housing and a heating assembly. The housing is provided with an airflow cavity extending along an axial direction of the housing, the heating assembly is disposed in the airflow cavity, the heating assembly is provided with multiple heating parts along a gas flow direction, and the outer diameters of the multiple heating parts steadily increase along the gas flow direction, so that the heating area of a heating part located at a downstream end of the airflow is increased; this can further protect the heating part at the downstream end and enable the air in the airflow cavity inside the heater to be fully heated, thus improving heating efficiency and hair drying efficiency of the hair dryer. The hair care device can help improve the efficiency of hair drying.
