A humidifier includes a water tank for containing a predetermined amount of water, a supporting base having a water chamber, a mist discharging channel, a mist generating module for generating a mist from the water in the water chamber and generating an air flow, and a noise reduction air duct. The noise reduction air duct has an air inlet extended from the water chamber for receiving the air flow and the mist, an air outlet extended to the mist discharging channel, and a detouring channel extended between the air inlet and the air outlet for detouring a direction of the mist from the water chamber to the mist discharging channel so as to reduce a speed of the mist for noise reduction.

A humidifier includes a first housing removably connected to a second housing that includes the majority of the electrical components of the humidifier. The first housing includes a first air inlet for accepting air; a first air outlet; a central chamber for holding water; a piezoelectric transducer installed in the central chamber for atomizing water; and a first electrical connector electrically connected to the piezoelectric transducer. The first housing is configured to discharge humidified air from the first air outlet. The second housing includes a second air outlet removably connectable to the first air inlet; a forced air source for forcing air out of the second air outlet; a second electrical connector configured to removably electrically connect to the first electrical connector; and an electric circuit electrically coupled to the forced air source for electrically powering the forced air source and electrically coupled to the second electrical connector for electrically powering the piezoelectric transducer.

A temperature-regulating fan includes a housing in which a chamber is formed, wherein the housing is provided with an air inlet and an air outlet communicated with the chamber, and an air flow passage is formed between the air inlet and the air outlet; a wet curtain assembly comprising an evaporation unit provided in the air flow passage; and an air flow driving assembly configured to drive the air flow entering through the air inlet to the air outlet to be blown out through the air flow passage. The temperature-regulating fan of the present application has high cooling and heating efficiency, and has a good market application prospect.
