[0002] The baby diaper is a kind of sanitary product commonly used by babies. Generally, the baby diaper is composed of three main parts: a skin-friendly layer, an absorption core layer, and a bottom layer, which can closely fit the human skin, quickly absorb the liquid permeated downward, and prevent the liquid from leaking everywhere. The baby diaper is a disposable product that can be easily replaced, without the need for washing, and is very convenient for caregivers.

[0003] However, the existing baby diaper has a small waist structure area, and after wearing for a long time, the accumulation of liquid makes the user feel a strong downward feeling in the waist, and the waist is easily pressed too much, which can cause marks on the waist, or in the case of lying down, the elastic adjustment part of the waist structure is easily pressed and cannot be adjusted, resulting in discomfort and even marks, which affects the comfort and experience. In addition, most baby diapers have a small capacity for liquid absorption, which is limited by the core body.
