This invention relates to a head-mounted cooler used for the objective of protecting body to achieve balanced physiological function and comfortableness when having fever or toothache, which generates cooling or heating characteristic application with a cooling chip. The cooling chip is composed of a contact surface, an electric fan, positive and negative power supply lines, a timer switch, a rotary switch, and a battery. The cooling chip is wrapped by a body seat and disposed on a head-mounted shaped arc cover plate. Utilizing the design of snap enables the head-mounted cooler to be arbitrarily positioned, and the cold or hot end is chosen for application of cold or hot therapy, so as to achieve the objective of reducing pain and fast recovering.本發明頭戴式致冷器,用於身體發燒或牙痛時,護著身體達到生理機能平衡與舒服之目的,係由致冷晶片,產生冷、熱特性應用,該致冷晶片係由接觸表面、電扇、正負極電源線、定時開關、旋鈕開關、電池組成,該致冷晶片由本體座將其包覆,套設在頭戴形弧蓋板上,利用按扣的設計可使頭戴式致冷器任意定位,取其冷、熱端作冷、熱敷的應用,使傷痛降低,並快速復原之目的。1...頭戴式致冷器2...致冷晶片7...旋鈕開關9...本體座11...頭戴形弧蓋板13...按扣19...弧凸點
