         [0029]    The water absorption filter element bearing part is of a grid-like structure or a net-like structure. 
         [0030]    The water absorption filter element  3  is higher than an inner wall of the water channel. 
         [0031]    The water absorption filter element  3  is of a multilayer net-like structure. 
         [0032]    The humidifying device further comprises a humidifying housing  6  which surrounds half of the air duct  1  and mates closely with the water channel  2 , wherein the water channel  2  surrounds the barrel-like outer wall of the air duct  1  and forms an inner humidifying housing  7  with the humidifying housing  6 ; and the water channel  2  is integrated with the inner humidifying housing  7  and surrounds the outer wall of the air duct  1 .

The water absorption filter element  3  functions to improve the evaporation efficiency and purify the water in the water channel  2 ; therefore, the water absorption filter element  3  is also designed to annularly extend along the air duct  1  to match with the annular structure in the water channel  2  so as to allow the air to pass through the water channel  2  and also to pass through the water absorption filter element  3 , thereby increasing the humidifying rate.
