Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to an air duct component and a humidifier. Background Art

[0002] A humidifier is a common electrical appliance that can adjust the humidity of the air. A humidifier generally heats the liquid stored inside the humidifier through an electric heating component. The heated liquid is atomized to form warm mist and output from the humidifier, thereby achieving the purpose of controlling the mist output temperature. However, existing humidifiers generally only heat the liquid, and do not heat the warm mist formed by atomization. Therefore, in order for existing humidifiers to output warm mist of the same temperature, it takes a longer time for the electric heating component to heat the liquid, resulting in low efficiency in outputting warm mist. Moreover, the heat generated by the electric heating component cannot be recycled, and the waste heat of the electric heating component is dissipated, resulting in a relatively large heat loss.
