Detailed Implementation

[0020] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The embodiments provided by this utility model are as follows: Figures 1-3As shown, a three-dimensional suspended absorbent core structure includes an absorbent core 10. A skin-friendly layer 20 is fixedly disposed on the upper part of the absorbent core 10, and a bottom film 30 is adhesively bonded to the lower part of the absorbent core 10. The two are bonded and fixed by an adhesive part 40, which is bonded to the center of the bottom of the absorbent core 10. Several vertical main absorbent grooves 50 are formed on the surface of the skin-friendly layer 20. The two sides of the main absorbent grooves 50 are connected to the side absorbent grooves 60. The main absorbent grooves 50 and the side absorbent grooves 60 pass through the skin-friendly layer 20 and extend to the top of the absorbent core 10. Several diffusion units 70 are disposed inside the absorbent core 10. The diffusion units 70 are arranged in a horizontal or vertical direction and are connected to each other by an elastic connecting strip 80. The ends of the main absorbent grooves 50 and the side absorbent grooves 60 away from the skin-friendly layer 20 are connected to the diffusion units 70 at the top of the absorbent core 10.

[0022] The elastic connecting band 80 has a cross-shaped structure. When the diffusion unit 70 is compressed, the diffusion unit 70 can slide slightly along the direction of the elastic connecting band 80. After the pressure is released, the elastic connecting band 80 drives the diffusion unit 70 to rebound, thereby achieving the effect of dispersing pressure and buffering impact.

[0023] When menstrual blood flows out, some of it directly penetrates into the absorbent core 10 along the skin-friendly layer 20, while some flows directly into the diffusion unit 70 along the main absorption groove 50, or into the diffusion unit 70 via the branch absorption groove 60. Then, some of the menstrual blood permeates from the diffusion unit 70 and is stored in the absorbent core 10, while some flows along the elastic connecting band 80 to other diffusion units 70, and finally permeates and is stored in the absorbent core 10. The diffusion unit 70 and the elastic connecting band 80 can increase the absorption speed of the absorbent core 10 and prevent menstrual blood from leaking out.

[0024] Preferably, the adhesive portion 40 has an I-shaped structure. The adhesive portion 40 includes a first adhesive area 41 and two second adhesive areas 42. The two second adhesive areas 42 are respectively connected to the first adhesive area 41 and are symmetrically arranged along the first adhesive area 41. The first adhesive area 41 is bonded to the bottom center of the absorbent core 10, and the two second adhesive areas 42 are respectively bonded to the front and rear ends of the bottom of the absorbent core 10. By setting the adhesive portion 40 to an I-shape, a sufficiently large independent suspended area can be left while ensuring the stable bonding between the absorbent core 10 and the bottom film 30. This allows the absorbent core 10 to flexibly adapt to the body curves during human activity, reducing displacement or side leakage caused by friction.

[0025] Preferably, the surface area of ​​the adhesive portion 40 is smaller than the bottom surface area of ​​the absorbent core 10.

[0026] Preferably, the main absorption grooves 50 in the central area of ​​the skin-friendly layer 20 are more densely distributed than the main absorption grooves 50 in the front and rear end areas of the skin-friendly layer 20. When menstrual blood flows out, it mainly flows to the central area of ​​the skin-friendly layer 20, and less flows to the front and rear areas of the skin-friendly layer 20. Therefore, this setting can reduce production costs and improve production efficiency without affecting the absorption effect.

[0027] Preferably, the angle between the auxiliary absorption groove 60 and the main absorption groove 50 is 45°. This arrangement makes the local distribution of the diffusion unit 70 more balanced, resulting in a more uniform absorption effect and greater wearing comfort.

[0028] Preferably, symmetrical protective wings 90 are fixedly provided on both sides of the bottom film 30. The protective wings 90 cover the sides of the underwear to prevent menstrual blood from seeping out from the sides of the sanitary napkin due to human activity. The wing-shaped structure of the protective wings 90 can increase the contact area with the underwear and form a horizontal protective barrier.

[0029] Preferably, the main absorption groove 50 and the branch absorption groove 60 have circular cross-sections, and the diffusion unit 70 has a square cross-section. The circular main absorption groove 50 and the branch absorption groove 60 have the advantages of low flow resistance, uniform stress distribution and high process adaptability, which can accelerate the efficient guidance of menstrual blood. The square diffusion unit 70 has the advantages of structural stability, uniform stress and anti-collapse, which can effectively resist the impact when menstrual blood flows out.

[0030] Preferably, a release paper 100 is attached to the bottom of the bottom film 30. The release paper 100 covers the bottom adhesive of the bottom film 30 to prevent the adhesive from coming into contact with external objects and getting contaminated with dust, hair or other impurities during storage and transportation, thus avoiding affecting the adhesiveness. When using the sanitary napkin, simply peel off the release paper 100 to expose the clean adhesive, and then accurately stick the sanitary napkin to the underwear. The operation is simple and convenient.

[0031] This utility model discloses a three-dimensional suspended absorbent core structure. Several vertical main absorbent grooves 50 are formed on the surface of the skin-friendly layer 20. Support absorbent grooves 60 are connected to both sides of the main absorbent grooves 50. Several diffusion units 70 are arranged horizontally or vertically within the absorbent core 10. The diffusion units 70 are connected to each other by elastic connecting strips 80. The ends of the main absorbent grooves 50 and the support absorbent grooves 60 away from the skin-friendly layer 20 are connected to the diffusion units 70 at the top of the absorbent core 10. This three-dimensional suspended absorbent core structure can evenly and efficiently absorb menstrual blood, preventing overflow due to heavy menstrual flow. It provides a good user experience and is especially suitable for nighttime use and sports activities.
