The nozzle 07 is configured to spray water along the transverse direction, water sprayed from the nozzle 07 can be directly sprinkled on the side walls of the second water absorbing medium 05 and the air duct 02, the side wall of the air duct 02 can guide the water sprinkled on the side wall onto the first water absorbing medium 04, a transparent window 010 is arranged on the side wall of the air duct 02 at a position opposite to the humidifying cavity 06, and a user can visually confirm water drops formed on the humidifying flow path through the transparent window 010, so that the state of humidification proceeding is visually confirmed, and the humidifier is conveniently controlled.

However, in the humidifier shown in fig. 1, since the water sprayed from the nozzles 07 along the transverse direction is directly sprayed onto the transparent window 010, the water is easily attached to the inner wall of the transparent window 010 in a droplet shape, thereby blocking the view of the user and affecting the accuracy of confirmation of the humidification progress state. Moreover, the direction of movement of water in the humidification chamber is disorderly, and it is difficult for a user to accurately determine the change in the amount of humidification water, which further affects the accuracy of confirmation of the humidification progress state.
