Description

Technical Field

[0001] The utility model relates to the technical field of female care products, in particular to a breathable sanitary napkin. Background Art

[0002] Sanitary napkin is a kind of sanitary product used by women during menstruation. It is divided into three layers from inside to outside: surface layer, absorbent core and bottom layer. When using, tear off the paper tape in the middle first, stick the side with glue to the middle of the underwear first, and stick the two wings to the narrowest part of the crotch. The existing sanitary napkin bottom layer often uses PE breathable bottom film to prevent leakage. The PE breathable bottom film is usually made by adding calcium carbonate to the PE masterbatch and then stretching to form micropores so that the bottom film has certain air permeability, but the air permeability of such micropores is very small. In order to ensure the absorption performance, the existing sanitary napkin often uses a mixture of high-density fluff pulp and high-molecular water-absorbing resin as the absorption core, but this high-density structure makes the overall air permeability of the sanitary napkin limited. In addition, the immunity of women during the physiological period will be slightly lower than usual, and menstrual blood contains a large amount of organic matter. If a sanitary napkin with poor air permeability is used, the skin will be in a humid and stuffy environment at all times, which is more likely to breed bacteria and endanger women's health. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a breathable sanitary napkin to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a breathable sanitary napkin, comprising a sanitary napkin main body; the sanitary napkin main body comprises a surface layer, a guide layer, a first absorption layer, a second absorption layer and a leak-proof bottom layer arranged in sequence from top to bottom, and a plurality of air holes are evenly distributed on the guide layer; a plurality of support columns are evenly arranged between the first absorption layer and the second absorption layer, so that an air layer is formed between the first absorption layer and the second absorption layer; a plurality of air cavities are evenly distributed on the top surface of the first absorption layer, and an inclined guide channel is arranged at the bottom of the air cavity, and the guide channel is connected to the air layer.

[0005] Furthermore, the surface layer is provided with side leakage prevention strips formed by the folds of the surface layer on both sides of the sanitary napkin body; a cavity is formed between the bottom of the side leakage prevention strips and the guide layer.

[0006] Furthermore, the cavity is filled with cotton.

[0007] Furthermore, the second absorption layer is in a U-shaped structure and is sleeved on the outside of the first absorption layer, so that the air interlayer forms a U-shaped structure.

[0008] Furthermore, springs are respectively provided at both ends of the air interlayer, the bottom end of the spring is fixed to the top surface of the second absorption layer, and the top end of the spring is fixed to the bottom surface of the guide layer.

[0009] Furthermore, anti-leakage baffles are respectively arranged at the front and rear ends of the surface layer, and both sides and outer ends of the anti-leakage baffles are respectively fixed to the surface layer.

[0010] Beneficial Effects

[0011] Compared with the prior art, the utility model has at least the following advantages:

[0012] Menstrual blood flows into the first absorption layer through the surface layer and the guide layer. The air cavity set on the top of the first absorption layer increases the liquid contact area and can store liquid. The liquid enters the air interlayer through the guide channel at the bottom of the air cavity and is absorbed by the second absorption core layer. The air interlayer improves the air permeability of the sanitary napkin during use. At the same time, the air holes, air cavities, guide channels and air interlayer cooperate to further improve the air permeability. The side leakage prevention strip prevents the sanitary napkin from leaking to the left and right sides. Under the support of the side leakage prevention strip, the leakage prevention sheet forms a pocket with an inner end opening to prevent the front and rear ends of the sanitary napkin from leaking.
