Description

Technical Field

[0001] This utility model relates to the field of diapers, and more particularly to a diaper with separate sections for urine and feces. Background Technology

[0002] Regular disposable diapers do not separate urine and feces, which can easily cause urine and feces to mix together, forming a paste-like substance on the diaper surface. This can irritate a baby's skin, affect breathability, and lead to skin problems.

[0003] In the prior art, patent application CN202310902603X discloses a dry and wet separation diaper, which divides the diaper surface into a urine area and a feces area to avoid the mixing of urine and feces and ensure the dryness of the micro-space and surface layer. However, it does not disclose the structure of the central partition guard, and judging from its drawings, the width of the central partition guard is relatively large, which also affects the diaper's absorption of urine and feces (loose stools), and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a diaper with separate sections for urine and feces, which separates urine and feces to prevent them from mixing on the surface and improves dryness.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A diaper with separate urination and defecation zones includes: an elastic waistband and an absorbent crotch. The absorbent crotch is connected to the elastic waistband at both ends. The absorbent crotch includes a top layer, a first distribution layer, an absorbent core layer, and a waterproof layer stacked from top to bottom. The top layer has a urination zone and a defecation zone connected front to back. The absorbent core layer includes a wood pulp layer and a first and a second annular groove disposed in the wood pulp layer. The first annular groove is located below the urination zone, and the second annular groove is located below the defecation zone. The first and second annular grooves are respectively filled with superabsorbent polymer particles.

[0007] The surface layer is made of pure cotton non-woven fabric, and the waterproof layer is made of waterproof and breathable membrane.

[0008] The surface layer is provided with micropores located in the urination area.

[0009] The microporous annular array is distributed above the inner side of the first annular groove.

[0010] A second diversion layer is provided between the absorbent core layer and the waterproof layer.

[0011] The first and second flow guiding layers are respectively made of hot air nonwoven fabric.

[0012] The surface layer has a conical hole located in the fecal area.

[0013] The beneficial effects of this utility model are as follows: A diaper with separate sections for urine and feces can be processed separately. After urine leaks into the absorbent core layer in the urine section, it is absorbed and expanded by the superabsorbent polymer particles in the first ring groove. This not only improves the absorption rate of urine and the dryness of the surface layer, but also uses the expanded superabsorbent polymer particles in the first ring groove to form a ring-shaped ridge on the surface layer, which restricts urine on the surface layer and prevents urine from entering the feces section along the surface layer, thus avoiding the mixing of urine and feces on the surface layer. Attached Figure Description

[0015] Figure 2 yes Figure 1 A schematic diagram of the structure of the absorbent crotch area after it has been unfolded.

[0016] Figure 3 yes Figure 2 A sectional view along line AA. Detailed Implementation

[0017] The following is combined with Figures 1 to 3 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 and Figure 2 The diaper shown has separate sections for urination and defecation, including: an elastic waistband 2 and an absorbent crotch 1, wherein the two ends of the absorbent crotch 1 are connected to the elastic waistband 2 to form a pull-up diaper structure.

[0019] like Figure 3 As shown, the absorbent crotch area 1 includes, from top to bottom, a surface layer 11, a first diversion layer 12, an absorbent core layer, and a waterproof layer 15, stacked sequentially. The surface layer 11 is made of pure cotton non-woven fabric, which is skin-friendly and reduces skin irritation. Urine or water from loose stools is diverted through the surface layer 11 into the first diversion layer 12, and then through the first diversion layer 12 into the absorbent core layer.

[0020] A second flow-guiding layer 14 is provided between the absorbent core layer and the waterproof layer 15. In this embodiment, the first flow-guiding layer 12 and the second flow-guiding layer 14 are respectively made of hot-air nonwoven fabric, which can guide the flow of urine in both the planar and thickness directions, thus facilitating the absorption of the absorbent core layer. In addition, the waterproof layer 15 is made of a waterproof and breathable membrane, which can prevent leakage while ensuring a certain degree of breathability.

[0021] like Figure 2As shown, a urine area 111 and a feces area 112 are connected front to back on the surface layer 11 for subsequent separate processing of urine and feces. The absorbent core layer includes a wood pulp layer 13 and a first annular groove 131 and a second annular groove 132 disposed in the wood pulp layer 13, as shown. Figure 3 As shown, the first annular groove 131 and the second annular groove 132 penetrate the thickness direction of the wood pulp layer 13.

[0022] In this embodiment, the first annular groove 131 is located below the urination area 111, and the second annular groove 132 is located below the defecation area 112. The first annular groove 131 and the second annular groove 132 are respectively filled with superabsorbent polymer particles 133. After urine leaks into the absorbent core layer in the urination area 111, it is absorbed and expanded by the superabsorbent polymer particles in the first annular groove 131. This not only improves the absorption rate of urine and the dryness of the surface layer 11, but also allows the expanded superabsorbent polymer particles 133 in the first annular groove 131 to form annular ridges on the surface layer 11. The annular ridges combine with the human body to restrict urine on the surface layer 11, preventing urine from entering the defecation area 112 along the surface layer 11 and preventing the mixing of urine and feces on the surface layer.

[0023] Similarly, after the water in the loose stool seeps into the absorbent core layer in the stool area 112, it is absorbed and expanded by the superabsorbent polymer particles in the second ring groove 132, forming a ring-shaped bulge on the surface layer 11, thus confining the loose stool in the stool area 112.

[0024] like Figure 2 As shown, micropores 114 are provided on the surface layer 11 in the urination area 111. The micropores 114 have a small diameter but are numerous, allowing urine to be quickly guided into the absorbent core layer below, where it is absorbed by the wood pulp layer 13, maintaining the dryness of the surface layer 11. In this embodiment, the micropores 114 are arranged in a ring array above the inner side of the first annular groove 131, significantly enhancing the downward flow effect of the surface layer 11 in the area above the inner side of the first annular groove 131. This facilitates the rapid expansion of the superabsorbent polymer particles 133 in the first annular groove 131, resulting in a fast response speed.

[0025] A conical hole 113 located in the defecation area 112 is provided on the surface layer 11, such as... Figure 2 As shown, the conical holes 113 are concentrated on the inner side of the second annular groove 132. Sloppy feces can be absorbed into the conical holes 113 by the water flow, thus filling the conical holes 113. The conical holes 113 are used to limit the loose feces (unformed stool), further improving the positional stability of the feces in the feces area 112.

[0026] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
