[0031] Embodiment

[0032] Combined with Figure 1 and Figure 2, an embodiment of the present utility model provides a fully - wrapped feminine sanitary napkin, which includes a sanitary napkin body. The sanitary napkin body includes:

[0033] A skin - friendly surface layer 10, having a surface;

[0034] A bottom layer 40, disposed below the skin - friendly surface layer 10;

[0035] A first absorbent layer 20, disposed between the skin - friendly surface layer 10 and the bottom layer 40;

[0036] A second absorbent layer 30, disposed between the first absorbent layer 20 and the bottom layer 40;

[0037] A first diversion groove 50, disposed on the surface of the skin - friendly surface layer 10. The first diversion groove splits the surface into a first area 11 near the center of the surface and a second area 12 on the opposite side of the first diversion groove 50 from the first area 11;

[0038] A second diversion groove 60, disposed on the first absorbent layer 20. When observed in a first direction perpendicular to the surface, at least part of the second diversion groove 60 is located in the second area 12;

[0039] A third diversion groove 70, disposed on the second absorbent layer 30. When observed in the first direction perpendicular to the surface, at least part of the third diversion groove 70 is located in the second area 12.

[0040] An embodiment of the present utility model provides a fully - wrapped feminine sanitary napkin. By arranging the skin - friendly surface layer 10, the first absorbent layer 20, and the second absorbent layer 30 in sequence, and respectively disposing the first diversion groove 50, the second diversion groove 60, and the third diversion groove 70 on the skin - friendly surface layer 10, the first absorbent layer 20, and the second absorbent layer 30, and making the second diversion groove 60 and the third diversion groove 70, the absorbed liquid can be restricted as much as possible in the first area 11 at the skin - friendly surface layer 10, can be restricted as much as possible inside the second diversion groove 60 on the second absorbent layer 30, and can be restricted as much as possible inside the third diversion groove 70 on the third absorbent layer. The design of multiple diversion grooves can play a role in diversion and isolation, effectively improving the water absorption capacity and water - locking capacity of the sanitary napkin body and reducing side leakage.

[0041] Further, one side of the first diversion groove 50 close to the first area 11 has a first groove top surface 51, and one side of the first diversion groove 50 close to the second area 12 has a second groove top surface 52. The first groove top surface 51 has a first height, the second groove top surface 52 has a second height, the first height is less than the second height, and the difference between the first height and the second height is at least 1.3 mm.

[0042] By setting a first groove top surface 51 with a first height and a second groove top surface 52 with a second height, and making the first height less than the second height, a height difference is formed between the inner side of the first diversion groove 50 close to the first region 11 and the outer side close to the second region 12, making it difficult for the liquid to leak from the first region 11 across the first diversion groove 50 to the second region 12, effectively improving the water locking and side leakage prevention capabilities of the sanitary napkin.

[0043] Furthermore, the first diversion groove 50 is in a closed curve shape or a curve shape with at least one opening.

[0044] Furthermore, the structures of the first diversion groove 50, the second diversion groove 60, and the third diversion groove 70 are the same. The first diversion groove 50, the second diversion groove 60, and the third diversion groove 70 with the same structure can reduce the complexity of the process.

[0045] To further improve the water locking ability of the sanitary napkin body, a first waterproof layer 80 is provided on the first absorption layer 20. The first waterproof layer 80 is arranged as follows: when observed along the first direction, the first waterproof layer 80 is provided on the surface of the first absorption layer 20 in the region where the second diversion groove 60 faces away from the first diversion groove 50. With this arrangement, the first waterproof layer 80 can reduce the leakage of the liquid in the second absorption layer 30 to the region where the first waterproof layer 80 is located on the first absorption layer 20 and prevent it from passing through the first absorption layer 20, effectively improving the water locking ability.

[0046] Furthermore, the sanitary napkin body further includes a wing 90. At least one side leakage prevention groove 91 is provided on the skin-friendly surface layer 10. At least one side leakage prevention groove 91 extends along the longitudinal direction of the skin-friendly surface layer 10 and is arranged between the first diversion groove 50 and the wing 90. The side leakage prevention groove 91 can further reduce the side leakage phenomenon.

[0047] Furthermore, a bulge is formed in the first region 11 of the skin-friendly surface layer 10. The structure and material of the bulge can refer to the existing sanitary napkin designs and will not be elaborated here.

[0048] Of course, the present utility model is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present utility model, and these equivalent deformations and replacements are all included in the scope defined by the claims of this application.
