[0002] In the field of infant care, diapers play a vital role as daily consumables. Ordinary diapers have problems such as poor breathability and insufficient waterproof performance, which can easily cause the user's skin to be in a damp and hot environment for a long time, leading to diaper rash and itchy skin. As people's requirements for quality of life continue to improve, higher standards are being set for the comfort and functionality of diapers. Therefore, developing a diaper that combines high water permeability and excellent waterproof performance has become an important direction for technological innovation in the industry, aiming to provide users with a dry, comfortable and healthy care experience.
[0003] During the use of diapers, insufficient absorbency of the material can lead to leakage when there is a large amount of urine. This not only soils clothes and bedding but also causes great inconvenience and distress to the user. Furthermore, the diapers are stuffy and not breathable, causing discomfort. To solve these problems, existing devices use composite fabric technology, combining a highly breathable microporous membrane with a highly absorbent non-woven fabric to achieve both breathability and waterproofing, effectively preventing side and back leakage. However, the above structure does not take into account the differences in body shape among infants and young children. An unsuitable waist size can cause pressure on the skin, reducing the convenience and comfort of wearing them, affecting their effectiveness, and failing to meet the needs of users. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a highly permeable and waterproof diaper, which aims to improve the problem of insufficient convenience and comfort caused by the inability to easily adjust the diaper to fit the waist size in the existing technology.

[0032] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3An embodiment of this utility model provides: a high-permeability waterproof diaper, including a diaper face 1, a wide surface band 3 fixedly connected to the top front side of the diaper face 1, multiple elastic bands 4 fixedly connected to the left and right sides of the wide surface band 3, a buckle 5 fixedly connected to the left side of the left elastic band 4, a waist belt 6 fixedly connected to the right side of the right elastic band 4, a fleece 7 fixedly connected to the outer wall of the waist belt 6, a hook 8 fixedly connected to the edge of the outer wall of the waist belt 6, a wide surface band 9 fixedly connected to the back side of the diaper face 1, multiple belt loops 10 fixedly connected to the back side of the wide surface band 9, multiple flexible pads 11 fixedly connected to the outer walls of the wide surface band 3 and the wide surface band 9, and a high-permeability waterproof mechanism 2 provided on the inner wall of the diaper face 1, the high-permeability waterproof mechanism 2 being used to ensure waterproofness and breathability;
[0033] Specifically, the wide band 3 on the diaper 1 increases the contact area, avoiding discomfort caused by pressure. These elastic bands 4 provide additional stretch, making the diaper more comfortable to wear and adapting to users of different body types. The buckle 5 works with the waistband 6 for easy wearing. The waistband 6 not only secures the diaper, but its outer surface 7, along with the hook side 8, locks it in place. The wide band 9 also increases the contact area and distributes pressure. These loops 10 allow the waistband 6 to pass through, forming a complete wearing structure. These flexible pads 11 provide additional comfort and protection. The highly breathable waterproof mechanism 2 ensures the diaper's waterproofness and breathability, keeping the user dry and comfortable.
[0034] Please see the appendix Figure 1 and attached Figure 4 The high-permeability waterproof mechanism 2 includes a waterproof and breathable membrane 201. The bottom of the waterproof and breathable membrane 201 is fixedly connected to the inner wall of the trouser surface 1. A water-absorbing layer 202 is fixedly connected to the top of the waterproof and breathable membrane 201. Multiple receiving grooves 203 are opened on the front side of the water-absorbing layer 202. Multiple water-absorbing gels 204 are fixedly connected to the inner wall of the receiving grooves 203. A flexible water-repellent layer 205 is fixedly connected to the top of the water-absorbing layer 202. Multiple water-permeable holes 206 are opened on the top of the flexible water-repellent layer 205.
[0035] Specifically, the high-permeability waterproof structure 2 provides a structure that is both waterproof and breathable, ensuring that the wearer remains dry and comfortable in various environments. The connection between the waterproof and breathable membrane 201 and the trouser surface 1 ensures the waterproof and breathable effect of the structure. The function of the absorbent layer 202 is to quickly absorb the permeable moisture and prevent moisture from accumulating inside the garment. The receiving grooves 203 can effectively hold the absorbent gel 204, which can quickly absorb and lock in moisture, further enhancing the overall water absorption capacity. The flexible water-repellent layer 205 is to prevent the absorbent gel 204 from directly contacting the skin and also to prevent moisture backflow while maintaining the breathability of the garment. The permeable holes 206 allow water to pass through while preventing external moisture from entering, achieving the dual functions of waterproof and breathable.
[0036] Please see the appendix Figure 1 and attached Figure 5 Multiple anti-leakage edges 12 are fixedly connected to the left and right sides of the pants 1, a butt pad 13 is fixedly connected to the back of the outer wall of the pants 1, and a lace 14 is fixedly connected to the top edge of the front side of the pants 1.
[0037] Specifically, the diaper's upper 1 is connected to a leak-proof side edge 12 with a leak-proof function. These leak-proof side edges 12 enhance the product's practicality and prevent urine leakage. The bottom pad 13 provides additional protection and support, ensuring the wearer's comfort during activities. The lace 14 enhances the overall aesthetics, making the diaper both functional and aesthetically pleasing.
[0038] Please see the appendix Figure 1 and attached Figure 5 A label 15 is fixedly connected to the front corner of the outer wall of the pants 1; a protective block 16 is fixedly connected to the left front part of the outer wall of the pants 1; a protective block 2 17 is fixedly connected to the right front part of the outer wall of the pants 1; and a brand label 18 is fixedly connected to the middle front part of the outer wall of the pants 1.
[0039] Specifically, the label 15 sewn onto the diaper surface 1 ensures the display of the diaper material and specifications. The protective block 16 on the diaper surface 1 is for providing additional protection and durability. Another protective block 17 on the diaper surface 1 echoes the protective block 16 and together enhances the diaper's protective performance. The brand logo 18 is attached to a prominent position on the front, displaying the diaper's brand identity and having a good advertising effect.
[0040] Working principle: The wide belt 1 3 and wide belt 2 9 on the trousers 1 have flexible pads 11, which increase the force-bearing area of the waist and ensure softness. Since the two sides of the wide belt 1 3 are connected to the elastic belts 4, the waist belt 6 and buckle 5 are connected through the elastic belts 4. Multiple belt loops 10 are fixed on the wide belt 2 9. When wearing, first pass the waist belt 6 through the belt loops 10, then pass the waist belt 6 through one side of the buckle 5 and then through the other side. After tightening to the appropriate size, hook the hook 8 onto the fleece 7 to complete the wearing. This structure adds an elastic structure to the normal waist belt 6 and increases the force-bearing area and softness, so that the structure can ensure comfort while being worn tightly, thus meeting the wearing needs.
