The utility model relates to a sanitary cotton leakproof structure, which comprises two leakproof units corresponding to and respectively facing an adsorption layer on the sanitary cotton and above the adjacent two outer sides.The leakproof units form a vertical leakproof wall, the vertical leakproof walls extend from the middle section toward the front end and the back end of the sanitary cotton respectively, and are close to the front end and the back end of the sanitary cotton respectively.The distance between the vertical leakproof walls of the leakproof units is formed. When it is used in the private places of women, the menstrual blood of women will touch the vertical leakproof walls along the distance in the middle position of the sanitary cotton, and flow through the adsorption layer in the front and back ends of the sanitary cotton respectively, so as to achieve the effect of leakproof, easy absorption of human menstrual blood and effective blockage prevention.一種衛生棉防漏結構，包含有二相對應且分別朝向該衛生棉上的一吸附層在鄰近兩外側上方的防漏單元。其中該些防漏單元分別形成一豎立防漏壁，該些豎立防漏壁分別由中間段分別朝向該衛生棉的前端、後端處延伸且分別靠近至與該衛生棉的前端、後端形成連接的前段及後段。藉此該些防漏單元的該些豎立防漏壁之間形成一距離，當用於女性私密處時，使女性經血沿著該衛生棉中間位置處的該距離並碰抵至該些豎立防漏壁，而分別流經該衛生棉前、後端的該吸附層所吸附，而達到防漏且易於吸收人體經血及具有效防堵的效果。
