The air humidifier can not only improve the humidification efficiency, but also make the blown air warmer in cold weather, so as to avoid the situation that the temperature of the air outlet or the air humidifier is lower than the room temperature, and improve the use comfort of the air humidifier. Compared with the humidification mode in which the air is heated by the heating assembly 60 and then mixed with the humidified air, the water vapor directly passes through the heating assembly 60 to directly heat the humidified air in the embodiment. The heating effect is better, and the problems of uneven temperature distribution of the water vapor and condensation of the humidified air after evaporation can be avoided. Specifically, the heating assembly 60 is arranged between the fan wheel assembly 30 and the air outlet grille 40. When the air humidifier is used, the water tank assembly 50 supplies water to the humidification filter screen assembly 20 to humidify the humidification filter screen assembly 20. The flow rate of the air on the surface of the humidification filter screen assembly 20 is increased by the fan wheel assembly 30, water molecules are evaporated into the air in the hollow structure to humidify the air, and the humidified air is heated by the heating assembly 60 under the negative pressure of the fan wheel assembly 30 and then blown out from the air outlet grille 40, so that the humidified air is heated. The humidified air generated by the humidification filter screen assembly 20 can be fully heated by the heating assembly 60 before being blown out through the air outlet grille 40, so that the heat loss is reduced. Since the heating assembly 60 is arranged close to the air outlet grille 40, the humidified air heated by the heating assembly 60 can be immediately blown out from the air outlet grille 40, the condensation backflow is reduced, the evaporation efficiency and the heating efficiency are improved, and the structure with high heating efficiency and humidification efficiency is realized.
