The invention discloses a solar energy purifying helmet, comprising a housing, a lining, a solar panel, a storage battery, a voltage conversion circuit, and an air purifying assembly. The solar panel is inlaid on the housing, the surface with a wafer is placed upward, a backboard is next to the housing, and a power output end is connected with the input end of the storage battery. The storage battery is used for storing electric energy sent by the solar panel, and is installed between the housing and the lining, and the output end is connected with the input end of the voltage conversion circuit. The voltage conversion circuit converts electric energy to voltage values which are suitable for operation of the air purifying assembly, and the voltage conversion circuit is installed between the housing and the lining, and the output end is connected with the input end of the air purifying assembly. The air purifying assembly is installed between the housing and the lining, and is used to purify air in the purifying helmet and air in the perimeter zone of the purifying helmet. The hamlet uses solar energy to provide electric energy for the internal of the hamlet. When the electric energy of the hamlet is insufficient, the hamlet automatically receives solar energy to charge the hamlet, so repeated operation of users to charge the hamlet is not needed, and the hamlet provides convenience for users to go out. In addition, the hamlet uses solar energy to supply power, and has no pollution and saves energy and protects environment.
