An ultrasonic humidifier according to an embodiment of the present invention includes: a water bottle accommodating water capable of generating humidification; a water bottle lid covering an upper opening surface of the water bottle and including a humidification outlet for discharging the humidification; and an ultrasonic humidification generating module which floats submersibly in the water accommodated in the water bottle and generates humidifying particles by using ultrasonic waves.

A filter arrangement for a humidifying device. The filter arrangement has: a rotatable body; a humidifying filter member arranged to be wetted with water; a guiding arrangement configured to guide water to a discharge region; and at least one discharge bucket arranged on the rotatable body. The at least one discharge bucket is configured to lift water from a tray and to discharge the water to the guiding arrangement as the rotatable body rotates in a first direction about a rotational axis. A humidifying device comprising a filter arrangement and a method for cleaning a humidifying filter member of a humidifying device are also provided.

The present disclosure discloses an all-in-one evaporative cooler. The all-in-one evaporative cooler comprises a fan with an air duct and a humidifier with water vapor outlets, wherein the water vapor outlets are communicated with the air duct, the humidifier and the fan are detachably connected, and the fan and the humidifier can respectively independently work after separated. The all-in-one evaporative cooler provided by the present disclosure simultaneously has three functions, namely a humidifying function, a blowing function and a cooling function, and is formed by assembling the humidifier and the fan which can respectively independently work. The independent humidifier and the independent fan have a small size so as to be convenient to carry, and a combination of the humidifier and the fan also has a small size so that arrangement, carrying and function selection are convenient and the diversified requirements of users can be met.

Evaporative humidifiers comprising: in vertical relationship and fluid communication with each other, a water inlet and a water reservoir downstream therefrom, positioned to receive water along a first fluid path; air inlet(s) and air outlet(s) in vertical relationship with the water inlet and/or reservoir, and a wick, downstream the water inlet, partially disposed in the reservoir to draw water therefrom to a wick portion in fluid communication with the air inlet(s) and the air outlet(s); and a motor-fan assembly downstream and in vertical relationship with the water inlet, upstream the reservoir. The reservoir and one or more of the air inlet(s) and the air outlet(s) generate an air current for drawing air, via the air inlet(s), from an external environment through the wick portion and move moistened air to the external environment via the air outlet(s) along a second fluid path at least partially separate from the first fluid path.
