[0025] The air humidifier of the embodiment can provide heating to the humidified air in cold weather, so that the humidified air is blown out after the temperature of the humidified air is increased. The air humidifier can not only improve the humidification efficiency of the air humidifier, but also make the blown air more warm and humid when used 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 first, and then the hot air is mixed with the humidified air, the water vapor directly passes through the heating assembly 60 in the embodiment to directly heat the humidified air. 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 added in the hollow structure of the humidifying filter screen assembly 20. When the air humidifier is used, the water tank assembly 50 supplies water to the humidifying filter screen assembly 20 to humidify the humidifying filter screen assembly 20, and the flow rate of the air on the surface of the humidifying filter screen assembly 20 is increased by the fan wheel assembly 30 to evaporate water molecules in the air in the hollow structure to humidify the air. The humidified air is heated by the heating assembly 60 located in the hollow structure, and then is blown out under the negative pressure of the fan wheel assembly 30, so that the humidified air is heated. The humidified air generated by the humidifying filter screen assembly 20 can be fully heated by the heating assembly 60 before being discharged by the high-speed rotation of the fan wheel assembly 30, the heat loss is reduced, and since the heating assembly 60 is arranged in the hollow structure, the air can be quickly heated by the heating assembly 60 after evaporation, the condensation backflow is reduced, and the evaporation efficiency is improved. The structure has both heating efficiency and humidification efficiency.

[0026] The humidifying filter screen assembly 20 of the hollow structure provides more negative pressure space and air flow space, so that the air can be evaporated and blown out smoothly, and the humidification efficiency of the air humidifier is improved.

[0027] The heating assembly 60 of the embodiment is arranged in the hollow structure and close to one side of the fan wheel assembly 30. Since the air in the entire hollow structure can be quickly concentrated on the side close to the fan wheel assembly 30 under the negative pressure of the fan wheel assembly 30, the heating assembly 60 arranged on the side close to the fan wheel assembly 30 can improve the full contact of the air in the hollow structure with the heating assembly 60, and improve the heat exchange efficiency of the heating assembly 60.

[0028] Since the hollow structure of the heating filter screen assembly is mostly in a cylindrical shape, the heating assembly 60 of the embodiment is arranged in a hollow column shape or a multi-ring shape, which is better adapted to the heating filter screen assembly. The hollow column or multi-ring arrangement can ensure that the contact surface of the heating assembly with the air is larger, so that the heat of the heating assembly 60 and the air can be better exchanged, the heat conversion efficiency is improved, and the blown hot air is more uniform and comfortable.

[0029] The heating element 60 in this embodiment includes, but is not limited to, resistive heating elements and ceramic heating elements.
