DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1 — Figure 5 As shown, the present embodiment provides a side leakage prevention waist-loop baby diaper, comprising a diaper body 1 and an air pump 2. The diaper body 1 is folded to form a leg guard hole 11 for covering the thigh root. The diaper body 1 is provided with a side leakage prevention elastic guard 12 around the leg guard hole 11 and on both sides of the absorbent core 14 to hold water and prevent leakage. The air pump 2 is connected to the inner side of the side leakage prevention elastic guard 12, and a shrinkable pressurized chamber is formed between the air pump 2 and the first waistband 13. When the pressurizing chamber of the air device 2 contracts, the air pump 2 quickly injects air into the diaper body 1, thereby pushing the anti-side leakage elastic guard 12 to expand outward, thereby making the area covered by the inner side of the anti-side leakage elastic guard 12 larger to prevent side leakage. If the anti-side leakage elastic guard 12 is not adjusted in place when wearing, the anti-side leakage elastic guard 12 can be quickly adjusted by controlling the rapid contraction of the pressurizing chamber. After wearing for a period of time, if the diaper moves, the pressurizing chamber can be controlled to quickly contract again at any time for rapid adjustment.
