AI Technical Summary
Existing sanitary pads have limited absorbency, which cannot meet the needs of women with urinary incontinence, and they cannot lock in the odor produced by urine, resulting in odor.
An incontinence-eliminating odor-removing sanitary pad was designed, which uses activated carbon particles to absorb odors and combines them with hot-air nonwoven fabric. The bottom surface of the breathable membrane is recessed with absorbent particles, including: absorbent particles, first absorbent particles, a cotton soft surface layer, a flow-guiding layer, and an anti-seepage layer. The absorbent particles are located above the flow-guiding layer, and the anti-seepage layer is located below the flow-guiding layer. The top surface of the flow-guiding layer is recessed with a first filling groove and a second filling groove. The absorbent particles and absorbent particles are respectively filled in their respective filling grooves. There is fluff pulp between the flow-guiding layer and the anti-seepage layer, and the cotton soft surface layer has flow-guiding holes.
It increases absorbency, reduces urine leakage and odor, and improves the user experience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary pads, and more particularly to an incontinence-eliminating and odor-eliminating sanitary pad. Background Technology
[0002] Panty liners prevent contact between the vulva and underwear, are typically used outside of menstruation, are easy to change, reduce stuffiness and bacterial growth in the vulva, and enhance protection for the vulva.
[0003] In addition, panty liners can absorb a small amount of bodily secretions, preventing the problem of secretions staining underwear. However, ordinary panty liners have limited absorbency and cannot meet the needs of women with urinary incontinence. They also cannot lock in the odor produced by urine, so improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide an incontinence-eliminating and odor-reducing sanitary pad that increases absorbency and locks in odors during use.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] An incontinence-inducing odor-eliminating sanitary pad includes: absorbent particles, first absorbent particles, a soft cotton surface layer, a flow-guiding layer, and a leak-proof layer. The soft cotton surface layer is disposed above the flow-guiding layer, and the leak-proof layer is disposed below the flow-guiding layer. A first filling groove is recessed in the top surface of the flow-guiding layer, and the first absorbent particles are disposed in the first filling groove. A second filling groove is recessed in the top surface of the flow-guiding layer, located outside the first filling groove, and the absorbent particles are disposed in the second filling groove.
[0007] The adsorbent particles are activated carbon particles.
[0008] The bottom surface of the guide layer is recessed and has a third filling groove located between the first filling groove and the second filling groove. The third filling groove contains second water-absorbing particles.
[0009] The first and second absorbent particles are made of SAP absorbent resin particles.
[0010] The impermeable layer is made of a waterproof and breathable membrane, and a decorative layer is provided on the bottom surface of the waterproof and breathable membrane.
[0011] The decorative layer is made of polyester nonwoven fabric.
[0012] The flow guiding layer is made of hot air nonwoven fabric.
[0013] The flow guiding layer and the seepage prevention layer are provided with fluff slurry, which is located within the closed area enclosed by the first filling groove.
[0014] The cotton-soft surface layer is made of pure cotton non-woven fabric, and the cotton-soft surface layer is provided with guide holes pointing downwards for the fluff pulp.
[0015] The beneficial effects of this utility model are as follows: An incontinence odor-eliminating sanitary pad is specially designed with a first filling groove and a third filling groove, which can be filled with first absorbent particles and second absorbent particles, increasing the absorbency and meeting the needs of women with urinary incontinence. After expansion, the cotton soft surface layer is tightened, forming a tight seal between the cotton soft surface layer and the human skin, reducing the problems of urine leakage and odor from the side. Moreover, the absorbent particles in the second filling groove can also absorb the escaped odor, firmly locking in the odor during use and improving the user experience. Attached Figure Description
[0016] Figure 1 This is a schematic diagram of the structure of this utility model;
[0017] Figure 2 yes Figure 1 A sectional view along line AA. Detailed Implementation
[0018] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.
[0019] like Figure 1 and Figure 2 The incontinence-reducing odor-eliminating sanitary pad shown includes: absorbent particles 6, first absorbent particles 5, a soft cotton surface layer 1, a diversion layer 7, and a leak-proof layer 8. The soft cotton surface layer 1 is disposed above the diversion layer 7, and the leak-proof layer 8 is disposed below the diversion layer 7. The edges of the soft cotton surface layer 1, the diversion layer 7, and the leak-proof layer 8 can be achieved by hot-pressing or ultrasonic welding, resulting in a stable structure.
[0020] In this embodiment, the flow guiding layer 7 is made of hot-air nonwoven fabric, which has good air permeability and flow guiding effect. A first filling groove 4 is recessed in the top surface of the flow guiding layer 7, which can be formed by roller pressing. The first absorbent particles 5 are placed in the first filling groove 4 to improve the water absorption effect.
[0021] like Figure 2 As shown, the top surface of the flow guiding layer 7 has a recessed second filling groove 3 located outside the first filling groove 4, and the adsorbent particles 6 are disposed in the second filling groove 3. In this embodiment, the adsorbent particles 6 are activated carbon particles, which can adsorb escaping odors, lock in odors during use, and improve the user experience.
[0022] A fluff pulp 10 is disposed between the flow-guiding layer 7 and the impermeable layer 8. The fluff pulp 10 is located within the enclosed area enclosed by the first filling groove 4. The fluff pulp 10 has good water absorption and low cost. In this embodiment, the cotton-soft surface layer 1 is made of pure cotton non-woven fabric, which has good softness and does not cause adverse skin irritation. The cotton-soft surface layer 1 is provided with flow-guiding holes 2 pointing downwards towards the fluff pulp. Through the flow-guiding holes 2, secretions or incontinent urine can be guided into the flow-guiding layer 7 and quickly delivered to the fluff pulp 10 through the flow-guiding layer 7. The fluff pulp 10 locks in the urine, and some urine is delivered from the edge of the fluff pulp 10 to the first absorbent particles 5, which increase the water absorption.
[0023] In addition, a third filling groove 12 is provided in the concave bottom surface of the guide layer 7, located between the first filling groove and the second filling groove. The third filling groove 12 is provided with second water-absorbing particles 11. In this embodiment, the first water-absorbing particles 5 and the second water-absorbing particles 11 are SAP water-absorbing resin particles, which have good water absorption effect and can absorb water and swell into hydrogel to tighten the cotton soft surface layer 1, so that a tight seal is formed between the cotton soft surface layer 1 and the human skin, reducing the problems of urine side leakage and odor from the side.
[0024] In this embodiment, the impermeable layer 8 is a waterproof and breathable membrane, which has good waterproof performance. A decorative layer 9 is provided on the bottom surface of the waterproof and breathable membrane 8 to prevent the impermeable layer 8 from being exposed and worn. The decorative layer 9 is made of polyester non-woven fabric, providing a velvety texture and a soft touch.
[0025] 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.
