[0027] Next, in combination with the accompanying drawings and the detailed implementation mode, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features to form a new embodiment.
[0028] As Figures 1-4 shown, an absorbent body with a hip protection function includes a pants body 70; the pants body 70 is provided with a penetrating surface layer 60, a built-in chip 3, and an absorbent core 4; the penetrating surface layer 60, the built-in chip 3, and the absorbent core 4 are arranged in sequence along the urine penetration direction A; the built-in chip 3 is used to neutralize ammonia, amine substances, and hydrogen sulfide substances in urine.
[0029] When an infant wears the absorbent body and excretes urine, the urine penetrates through the penetrating surface layer 60 and then enters the built-in chip 3. At this time, various substances in the urine quickly react with the built-in chip 3. After using the built-in chip 3 to neutralize harmful substances such as ammonia, amine substances, and hydrogen sulfide in the urine, the urine then enters the absorbent core 4 and is absorbed and stored by the absorbent core 4. Therefore, an absorbent body with a hip protection function provided by the present utility model can chelate amine substances, ammonia, and hydrogen sulfide substances in urine by arranging a penetrating surface layer 60, a built-in chip 3, and an absorbent core 4 in the pants body 70, effectively eliminating the urine smell and reducing the harm caused by amine substances, ammonia, and hydrogen sulfide substances in the urine to the skin. Moreover, by arranging the penetrating surface layer 60, the built-in chip 3, and the absorbent core 4 in sequence along the urine penetration direction, the direct contact between the built-in chip 3 and the air 9 can be avoided through the barrier of the penetrating surface layer 60, so as to avoid the problem of excessive microorganisms due to direct contact with the air, and avoid the pollution of the machine due to the direct contact between the built-in chip 3 and the working surface of the machine.
[0030] As a further preferred implementation mode of the present utility model, as Figure 9As shown, a guiding structure 41 is provided on the side of the built-in chip 3 close to the penetration surface layer 60. The guiding structure 41 includes a diffusion structure and a penetration structure. The diffusion structure is used to diffuse urine along the built-in chip 3, and the penetration structure is used to guide urine to penetrate toward the side of the built-in chip 3 close to the absorbent core 4.
[0031] The guiding structure 41 is a chip front fluff layer provided on the side of the built-in chip 3 close to the penetration surface layer 60. The chip front fluff layer includes chip front weft fluff and chip front warp fluff. The chip front weft fluff forms a diffusion structure, and the chip front warp fluff forms a penetration structure. A chip back fluff layer 42 is provided on the side of the built-in chip 3 close to the absorbent core 4. When urine flows through the built-in chip 3, the urine diffuses along the built-in chip 3 toward the periphery under the guiding action of the chip front weft fluff of the chip front fluff layer, and penetrates downward through the built-in chip 3 into the chip back fluff layer 42 under the penetration guiding action of the chip front warp fluff.
[0032] As a further preferred embodiment of the present invention, the penetration surface layer 60 includes an outer surface layer 1 and an inner surface layer 2, and the outer surface layer 1 and the inner surface layer 2 are sequentially arranged along the direction close to the built-in chip 3. A first surface layer back fluff layer 43 is provided on the side of the outer surface layer 1 close to the inner surface layer 2. A surface layer front fluff layer 44 is provided on the side of the inner surface layer 2 close to the outer surface layer 1. A second surface layer back fluff layer 45 is provided on the side of the inner surface layer 2 close to the built-in chip 3. When an infant wears the absorbent body and excretes urine, the urine penetrates into the material surface from the outer surface layer 1, is conducted and diffused by the first surface layer back fluff layer 43 of the outer surface layer 1, then enters the surface layer front fluff layer 44 of the inner surface layer 2 downward, and after being conducted and diffused by the surface layer front fluff layer 44, the urine penetrates downward through the inner surface layer 2 into the second surface layer back fluff layer 45, and after being further conducted and diffused by the second surface layer back fluff layer 45, the urine enters the chip front fluff layer of the built-in chip 3 downward.
[0033] Preferably, the fluff layer 43 on the back side of the first surface layer includes weft fluff and warp fluff on the back side of the first surface layer; the fluff layer 44 on the front side of the surface layer includes weft fluff and warp fluff on the front side of the surface layer; the fluff layer 45 on the back side of the second surface layer includes weft fluff and warp fluff on the back side of the second surface layer. When the absorbent body is worn by an infant and urine is excreted, after the urine penetrates from the outer surface layer 1 into the material surface, it is guided by the weft fluff on the back side of the first surface layer of the outer surface layer 1 to spread the urine along the outer surface layer 1 to the periphery, and is guided by the warp fluff on the back side of the first surface layer to penetrate the urine downward into the fluff layer 44 on the front side of the surface layer of the inner surface layer 2. The weft fluff on the front side of the surface layer of the inner surface layer 2 guides the urine to spread along the inner surface layer 2 to the periphery, and is guided by the warp fluff on the front side of the surface layer to penetrate the urine downward through the inner surface layer 2 into the fluff layer 45 on the back side of the second surface layer. The urine is guided by the weft fluff on the back side of the second surface layer to spread to the periphery, and is guided by the warp fluff on the back side of the second surface layer to penetrate the urine downward into the fluff layer on the front side of the inner chip 3.
[0034] Of course, in addition to this, the penetration surface layer 60 can also be set to other structures according to actual needs.
[0035] The fluff density of the fluff layer 42 on the back side of the chip is greater than that of the fluff layer on the front side of the chip. The fluff density of the fluff layer on the front side of the chip is greater than that of the fluff layer 45 on the back side of the second surface layer. The fluff density of the fluff layer 45 on the back side of the second surface layer is greater than that of the fluff layer 44 on the front side of the surface layer. The fluff density of the fluff layer 44 on the front side of the surface layer is greater than that of the fluff layer 43 on the back side of the first surface layer. By adopting the above settings, the fluff density can be used to make the urine penetrate through the outer surface layer 1, the inner surface layer 2, and the inner chip 3 in sequence under the action of gravity and the fiber siphon principle and then penetrate into the absorbent core 4, and then enter the absorbent core 4 and be absorbed and locked by the water-absorbing powder (i.e., sodium polyacrylate particles) of the absorbent core 4. During this process, the fluff density of the outer surface layer 1, the inner surface layer 2, and the inner chip 3 can be used to effectively control the penetration speed of the urine, so that when the urine penetrates through the inner chip 3, it can fully react with the inner chip 3 under the action of the weft fluff and warp fluff on the front side of the chip of the inner chip 3 to fully exert the performance of the inner chip 3 and ensure its efficacy.
