Fireproof helmet

The utility model provides a fireproof helmet which comprises a helmet shell, and a buffer layer and a lining are sequentially arranged on the inner side of the helmet shell from outside to inside. The buffer layer comprises a buffer structure layer and a foam layer, and the foam layer is close to one side of the lining; the buffer structure layer comprises a plurality of deformable bodies arranged between the foam layer and the helmet shell, and the deformable bodies generate arch deformation after being stressed. According to the utility model, the buffer layer is provided with the buffer structure layer and the foam layer, the foam layer has a series of characteristics of good elasticity, light weight, convenience in use, flexibility in bending, ultrathin volume, reliable performance and the like, the buffer structure layer comprises a plurality of deformable bodies, and the deformable bodies can generate bow-shaped deformation after being stressed; in this way, elastic buffering can be effectively formed
