Abstract: A wearable air conditioner includes a shell for being worn around a wearing portion of a user, a fan and a temperature regulating member disposed in the shell. The shell includes a first air passage, a first accommodating chamber, at least one air outlet in communication with the first air passage, and vent holes in communication with the first accommodating chamber. The temperature regulating member is configured for generating heat energy or cold energy. The temperature regulating member is in thermal connection with a sidewall of the first accommodating chamber. An airflow generated by the fan is capable of entering the first air passage and then exiting the shell via the at least air outlet.
