It should be noted that, in the present embodiment, when urine breaks through the primary protective layer, the side absorption layer 32 is arranged on both sides of the slow absorption surface layer 23 as a secondary protection, and the overflowed urine is absorbed by the absorption and diversion surface layer 323 and diverted to the absorption filling layer 322, and the absorption filling layer 322 quickly absorbs the overflowed urine again, and an absorbent anti-leakage film 321 is provided at the bottom of the side absorption layer 32 for leakage protection.

The working principle of the utility model is:

In the utility model, when the baby urinates at night after wearing the diaper, the urine flows to the top of the diaper body 10, and the quick-absorbing core 21 inside the bottom anti-leakage layer 31 quickly absorbs the discharged urine. As the quick-absorbing core 21 continuously absorbs the urine, the filler gradually becomes saturated. When the baby turns over while sleeping, the urine in the quick-absorbing core 21 may be squeezed out. The anti-reverse osmosis layer 22 on the top of the quick-absorbing core 21 and the slow-absorbing surface layer 23 provide a protection against the overflowed urine. Among them, the anti-reverse osmosis layer 22 inhibits the overflow of urine, and the multiple absorbent cotton strips 231 on the inner wall of the slow-absorbing surface layer 23 absorb the overflowed urine. The absorbent cotton strips 231 are staggered and contact each other, which ensures that the urine is absorbed while reducing the probability of urine extravasation.

When urine breaks through the primary protection layer, the side absorption layer 32 is arranged on both sides of the slow absorption surface layer 23 as secondary protection, and the overflowed urine is absorbed and guided by the absorption and diversion surface layer 323 to the absorption filling layer 322, and the absorption filling layer 322 quickly absorbs the overflowed urine again, and an absorbent leak-proof film 321 is provided at the bottom of the side absorption layer 32 for leakage protection. At the same time, the bottom leak-proof layer 31 protects the fast absorption core 21 and the bottom of the side absorption layer 32 from leakage, preventing urine from leaking from the bottom of the diaper and affecting the baby's sleep. The trouser leg tightening belts 11 at both ends of the bottom leak-proof layer 31 tighten the trouser legs worn by the baby to help prevent the baby's excrement from leaking sideways.
