Embodiment 1

[0042] see Figure 1-Figure 3 , in the flow guide structure provided by this embodiment, the depressions and projections in the first flow guide layer 1 are elongated structures respectively, and the depressions and projections are parallel to each other; the depressions and projections are respectively multiple , the two are arranged crosswise.

[0043] The section of the protruding part along the direction perpendicular to its extending direction is arc-shaped, and the protruding part protrudes toward the surface layer 3; the concave part is flat. In this embodiment, the channel-shaped liquid temporary storage area is formed by cooperating with the surface layer at the recessed part.

[0044] In this solution, the surface layer 3 is made of perforated non-woven fabric, and the second flow guide layer 2 is made of plain non-woven fabric.

[0045] In application, the liquid is absorbed by the surface layer 3 and reaches the flow guide layer, wherein the first flow guide laye...

Embodiment 2

[0047] see Figure 4-Figure 6, in the diversion structure provided by this embodiment, there is one raised part, which is in the shape of a flat plate; there are multiple depressed parts, which are dispersedly arranged on the raised part; the inner wall section of the depressed part is arc-shaped, and the inner wall of the depressed part The wall surface is spherical or similar to a spherical surface; the depression gradually moves away from the surface layer 3 from its opening to the maximum depth.

[0048] In the diversion structure provided in this embodiment, the surface layer 3 includes a plurality of arc-shaped parts parallel to each other, and each arc-shaped part is arranged in sequence along the first direction and connected as a whole; the above-mentioned first direction is the busbar with the arc-shaped parts vertical. The surface layer 3 is perforated and formed by 3D pressing. Specifically, the first flow guiding layer 1 is a non-woven fabric layer with circular...

Embodiment 3

[0051] see Figure 7-Figure 9 , in the diversion structure provided by this embodiment, the raised portion is a circular raised portion, which protrudes toward the surface layer 3, and there are multiple raised portions distributed on the depressed portion in multiple rows, and the raised portion can specifically be distributed in a matrix. The number of depressions is one.

[0052] The surface layer 3 is a perforated non-woven fabric layer. During application, the liquid is absorbed by the surface layer 3 and reaches the raised part. The raised part quickly conducts the liquid downward. At the same time, the raised part has a small liquid holding capacity due to the low density of the material. Moreover, the second flow guide layer 2 is separated from the raised portion and the core body 5 , so the raised portion can well reduce liquid reverse seepage and further improve the dryness of the flow guide structure.

[0053] In the flow guide structure provided by the above embo...

Abstract

The invention discloses a flow guide structure. The flow guide structure comprises a surface layer, a flow guide layer, a core body and a bottom film which are stacked in sequence, wherein the flow guide layer is of a multilayer structure and at least comprises a first flow guide layer and a second flow guide layer, the first flow guide layer is close to the surface layer, and can not only guide aliquid horizontally and vertically, but also cooperate with the surface layer to form a liquid temporary storage area, the second flow guide layer is close to the core body, and is used to quickly guide the liquid guided by the first flow guide layer to the core body, and the second flow guide layer and the first flow guide layer are arranged in an overlapped manner. In the flow guide structure,the flow guide layer with the multilayer structure is arranged between the surface layer and the core body, the first flow guide layer and the surface layer cooperate to form the liquid temporary storage area, the liquid can be temporarily stored when a large amount of the liquid reaches the flow guide structure, the situation that the flow guide structure cannot perform quick absorption, so thatthe liquid is accumulated on the surface of the flow guide structure, and thereby leaking occurs is prevented, and the absorption capacity is increased; and the second flow guide layer cooperates withthe core body to form an absorption area to quickly absorb the liquid in the liquid temporary storage area to prevent the liquid from seeping back to the surface layer to ensure dryness. The invention also discloses an absorption product.

Description

technical field [0001] The invention relates to the technical field of hygiene products, more specifically, to a flow-guiding structure, and to an absorbent product. Background technique [0002] Existing absorbent products are various, such as baby diapers, baby pull-up pants, sanitary napkins, etc. All kinds of absorbent products are provided with diversion structures, and the diversion structures include surface layers, cores and bottom films arranged in sequence. The existing diversion structure is simple, not dry enough in use, and is prone to leakage when a large amount of liquid suddenly reaches the diversion structure. [0003] Therefore, how to improve the dryness of the flow guide structure and avoid leakage is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a diversion structure, which is additionally equipped with a diversion layer of multi-layer structure, which can...
