The sanitary towel made by the utility model has good leakage-proof effect, strong absorption capacity and good diversion effect. However, in actual use, menstrual blood tends to ooze outward from both sides of the root of the thigh due to the user's movement.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the above problems, the utility model provides a three-dimensional leakproof sanitary towel, which solves the technical problem that the menstrual blood is easy to seep out from two sides in the using process of the sanitary towel in the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a three-dimensional leak protection sanitary towel, includes the sanitary towel main part, the sanitary towel main part including fill up the body and set up in outer wing on filling up the body, fill up the body including top layer, sandwich layer and the bottom that connects gradually, the definition the sanitary towel main part is including front and back, the back of sanitary towel main part is provided with the gum, top layer central point puts and is provided with the bar recess, bar recess both sides are provided with two protection archs, protection protruding symmetry set up in the both sides of bar recess, two the bellied both ends of protection to the length direction of sanitary towel main part extends and forms a confined annular arch at terminal interconnect.

Further, the height of the protection protrusion is 5mm to 8 mm.

Furthermore, a plurality of air holes are uniformly formed in the surface layer, and the air holes are circular.

Further, the length of the strip-shaped groove is 5cm to 10cm, and the width of the strip-shaped groove is 2cm to 4 cm.

Furthermore, extension parts are arranged at two ends of the sanitary towel main body in the length direction.

Further, the width of the sanitary napkin main body is one half of the width of the extension portion.

By adopting the technical scheme, the beneficial effects of the utility model are that:

1. a strip-shaped groove is formed in the center of the surface layer, and the strip-shaped groove is directly attached to the pudendum of a female; two sides of the strip-shaped groove are provided with two protective bulges, the aim of leakage prevention is achieved through a three-dimensional structure, the two protective bulges can be abutted against the skin on two sides of the private part of a female, on one hand, a hollow space is formed between the two protective bulges and the private part, and on the other hand, the sanitary towel is not directly attached to the private part to cause poor air permeability; the two ends of the protection bulge extend like the length direction of the sanitary towel main body and are connected with each other at the tail end to form a closed annular bulge, so that the sanitary towel is well matched with the female pudendum to achieve the aim of leakage prevention.

2. The height of the protection protrusion is set to be 5mm to 8mm, so that discomfort of a user due to overhigh height is avoided, and the leakage-proof effect is poor due to overlow height.

3. Evenly be provided with a plurality of bleeder vents on the top layer, the bleeder vent is circular, can make the user avoid moist and then breed the bacterium more and take place the infection at the gas permeability of using.

4. The length of bar recess is 5cm to 10cm, and the width is 2cm to 4cm, thereby the reasonable scope that thereby this numerical value set up and reachs through big data acquisition women private parts data, can adapt to the use of the vast majority of women.
