Description

[0002] Air-conditioned clothing keeps the user cool and comfortable by increasing the air flow between the inside and outside of the clothing. Air-conditioned clothing is usually powered by a lithium battery, and in order to ensure that users can stay cool in multiple environments, air-conditioned clothing is usually equipped with multiple level buttons to allow consumers to select the output level of the air-conditioned clothing according to their needs. However, due to the limitation of the traditional one-chip microcomputer control system, if the output level of the air-conditioned clothing is too high, the one-chip microcomputer will generate serious heat. Thus, the output level of the air-conditioned clothing will be limited, which will greatly affect the user's experience. In addition, the output level of many air-conditioned clothing is adjusted by buttons, but the number of output levels is limited; having too many level buttons can discourage users, and having too few level buttons can make it difficult for users to find the appropriate output level, and it is inconvenient for users to adjust the output level when they cannot see the buttons.
