Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically to a sanitary napkin. Background Technology

[0002] In related technologies, to ensure good absorbency in sanitary napkins, the absorbent layer is typically designed to be large to prevent leakage due to excessive user activity. However, in actual use, users change sanitary napkins regularly. When the user's activity level is low, menstrual blood is usually only absorbed in a localized area of ​​the absorbent layer, resulting in low utilization and material waste.

[0003] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0006] According to one embodiment of the present invention, the adjacent branch guide channels of the two adjacent main flow channels are staggered.

[0007] According to one embodiment of the present invention, there is a gap between two adjacent branch guide channels in the plurality of branch guide channels that are connected on both sides of each of the above-mentioned main flow channels, and one end of the branch guide channel that is connected to another main flow channel adjacent to the main flow channel is located within the gap.

[0008] According to one embodiment of the present invention, the projection of the aforementioned flow guiding layer in its thickness direction coincides with the projection of the absorption layer in its thickness direction.

[0009] According to one embodiment of the present invention, the multiple branch guide channels on both sides of each of the above-mentioned main flow channels are symmetrically arranged.

[0010] According to one embodiment of the present invention, the branch guide channel and the main guide channel are set at an angle α, where 45°≤α≤90°.

[0011] According to one embodiment of the present invention, the two ends of the absorbent layer are folded inward to form a multilayer structure.

[0012] According to one embodiment of the present invention, the surface layer described above is made of silk.

[0013] The beneficial effects of this invention are as follows: By setting a main flow channel and branch flow channels on the flow guiding layer, the menstrual blood can be diffused to all parts of the absorbent layer under the action of the main flow channel and branch flow channels, thereby improving the utilization rate of the absorbent layer and avoiding material waste.

[0020] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0024] Please refer to Figure 1 , Figure 2 as well as Figure 3 This utility model provides a sanitary napkin, comprising: a bottom film 1, an absorbent layer 2, a diversion layer 3, and a top layer 4. The bottom film 1, absorbent layer 2, diversion layer 3, and top layer 4 are arranged sequentially from bottom to top. The diversion layer 3 has multiple parallel main flow channels 31, and each main flow channel 31 has multiple branch flow channels 32 connected to both sides. Specifically, the multiple branch flow channels 32 on both sides of each main flow channel 31 are symmetrically arranged.

[0025] In practical applications, menstrual blood permeates downward through the surface layer 4. When the menstrual blood enters the main flow channel 31 and branch flow channel 32 of the flow guiding layer 3, the menstrual blood can diffuse to the surroundings under the action of the main flow channel 31 and branch flow channel 32, so that the absorption layer 2 can absorb the menstrual blood everywhere, thereby improving the utilization rate of the absorption layer 2.

[0026] In some preferred embodiments, the adjacent branch guide channels 32 of the two adjacent main flow channels 31 are staggered. This technical solution allows menstrual blood to diffuse sufficiently in all directions, enabling the absorption layer 2 to absorb menstrual blood at all points, further improving the utilization rate of the absorption layer 2.

[0027] In some preferred embodiments, there is a gap between adjacent branch guide channels 32 connected to both sides of each main flow channel 31, and another main flow channel 31 adjacent to the main flow channel 31 is connected to it, with one end of the branch guide channel 32 adjacent to the main flow channel 31 located within the gap. This technical solution allows menstrual blood to flow to all parts of the absorbent layer 2 under the action of the main flow channel 31 and the branch guide channels 32, further improving the utilization rate of the absorbent layer 2.

[0028] In some preferred embodiments, the projection of the flow guiding layer 3 in its thickness direction coincides with the projection of the absorption layer 2 in its thickness direction. This technical solution allows for full utilization of all parts of the absorption layer 2, avoiding material waste.

[0029] In some preferred embodiments, the branch flow channel 32 and the main flow channel 31 are arranged at an angle α, where 45°≤α≤90°. By designing the branch flow channel 32 and the main flow channel 31 at an angle α, menstrual blood can be effectively diffused to all parts of the absorbent layer 2 under the action of the branch flow channel 32.

[0030] In some preferred embodiments, the two ends of the absorbent layer 2 are folded inward to form a multi-layer structure. In specific applications, by folding both sides of the absorbent layer 2 inward to form a multi-layer structure, the absorbency of the sanitary napkin is further improved, meeting different user needs.

[0031] In some preferred embodiments, the surface layer 4 is made of silk. This technical solution improves the skin-friendliness and comfort of sanitary napkins, and the silk contains natural sericin, which has certain antibacterial properties, reducing odor, helping to maintain feminine hygiene, and reducing the risk of infection.

[0032] In summary, in one or more embodiments of this utility model, the sanitary napkin of this utility model, by setting a main flow channel and branch flow channels on the flow guiding layer, allows menstrual blood to diffuse to all parts of the absorbent layer under the action of the main flow channel and branch flow channels, thereby improving the utilization rate of the absorbent layer and avoiding material waste.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
