This invention relates to a doze prevention hat structure, comprising a hat body disposed with a receiving slot a light emitting element and several massagers disposed on the hat body, wherein each massager is disposed to the rear end of the hat body an elastic sensor surrounding the inside position of the top end of the receiving slot and disposed with two electrodes capable of detecting brainwave and a processor connected with a power source, capable of controlling the light emitting element and the massagers. The elastic sensor is for detecting the brainwave and transmitting it to the processor. The processor determines and interprets whether the detected brainwave signal is the brainwave curve in the sleeping stage. If yes, the processor will control the light emitting element to flash for reminding the people around the user to wake up the user while the processor will also control the massagers to vibrate and massage the acupuncture points at the rear head of the user to achieve the effect of refreshing.一種防止瞌睡之帽子結構,包括:一帽體設有一容置槽;該帽體上並設有一發光元件及數按摩器,各該按摩器係設置於該帽體後端;一彈性感測件係環繞該容置槽頂端內側位置,設有兩電極可偵測腦波;一處理器係連接一電源,可控制該發光元件及該按摩器,該彈性感測件係將偵測到的腦波傳送給該處理器,該處理器判斷並解讀偵測到的腦波訊號是否為睡眠階段的腦波圖形;如果為睡眠狀態的腦波圖形,該處理器就會控制該發光元件閃爍用以提醒使用者周圍的人需要叫醒使用者,且該處理器也會控制該按摩器震動並按摩使用者後腦之穴位,達到提神醒腦的效果。10‧‧‧帽體11‧‧‧容置槽20‧‧‧發光元件30‧‧‧按摩器40‧‧‧彈性感測件41‧‧‧電極50‧‧‧處理器
