The emergency absorbent core 12 is placed in the opening belt as a backup for use in an emergency when a woman goes out and does not have an extra sanitary napkin body 1.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, the preferred embodiment of the absorbent core structure of the sanitary napkin provided by the present invention is as follows: Figures 1 to 4 As shown: the absorbent core component 2 includes a novel absorbent core 21 and an insulating pad 22. The novel absorbent core 21 is fixedly sewn to the top of the insulating pad 22. The insulating pad 22 is fixedly adhered to the surface of the sanitary napkin pad 11. The insulating pad 22 includes an adhesive tape 221. The adhesive tape 221 is adhered to the surface of the sanitary napkin pad 11. The insulating pad 22 is connected to the sanitary napkin pad 11 through the adhesive tape 221. The novel absorbent core 21 includes an absorbent core first layer 211, an absorbent core second layer 212, a drawstring 213, an absorbent core third layer 214, and an annular baffle 215. The absorbent core second layer 212 is sewn to the bottom of the absorbent core first layer 211. The absorbent core third layer 214 is sewn to the bottom of the absorbent core It is connected to the bottom of the second layer 212 of the absorbent core, the drawstring 213 is sewn to the side end of the second layer 212 of the absorbent core, the annular baffle 215 is fixedly sewn to the top of the isolation pad 22, the side end of the second layer 212 of the absorbent core sewn with the drawstring 213 is provided with an inner groove, the drawstring 213 is sewn in the inner groove, the second layer 212 of the absorbent core is provided with an annular baffle 215, the annular baffle 215 functions to prevent liquid from overflowing from the side of the new absorbent core 21, the first layer 211 of the absorbent core is set to a water-absorbing and permeable material, the second layer 212 of the absorbent core is a liquid storage material, the third layer 214 of the absorbent core is a liquid-impermeable material, and the drawstring 213 is ductile and can be stretched.

[0033] Specifically, the novel absorbent core 21 includes a first absorbent core layer 211, a second absorbent core layer 212, and a third absorbent core layer 214. The first absorbent core layer 211 mainly absorbs liquid and absorbs the liquid into the second absorbent core layer 212. The surface of the first absorbent core layer 211 is designed for one-way absorption. The liquid is absorbed by the first absorbent core layer 211 and enters the lower layer from the upper layer, and cannot return from the lower layer to the upper layer. After the first absorbent core layer 211 absorbs the liquid, the second absorbent core layer 212 stores the liquid to prevent it from flowing out. The annular baffle 215 on the outer surface of the second absorbent core layer 212 serves as a structure to prevent the liquid from flowing out. The third absorbent core layer 214 is the bottom layer of the novel absorbent core 21. The third layer 214 of the absorbent core is not permeable, and liquid cannot pass through the third layer 214 of the absorbent core, preventing liquid from flowing out of the third layer 214 of the absorbent core. The isolation pad 22 acts as a partition. The isolation pad 22 is not permeable, preventing liquid from passing through the isolation pad 22 and flowing into the sanitary napkin liner 11. In an emergency, pull out the drawstring 213, pull the drawstring 213, and use the drawstring 213 to pull off the new absorbent core 21 and the isolation pad 22 at the same time. After pulling off the new absorbent core 21, the emergency absorbent core 12 in the sanitary napkin liner 11 will be inflated and pop out to form a new emergency absorbent core 12, so that women can use the sanitary napkin body 1 for a second time in an emergency.

[0034] The working process of the utility model is as follows:

[0035] Since the sanitary napkin body 1 is a disposable product, when a woman goes out without carrying an extra sanitary napkin body 1, an absorbent core component 2 and an emergency absorbent core 12 are designed inside the sanitary napkin body 1. An open pocket is set in the middle part of the sanitary napkin pad 11, and the emergency absorbent core 12 is placed in the open belt as a spare, which can be used in an emergency when a woman goes out and does not have an extra sanitary napkin body 1. The new absorbent core 21 includes a first absorbent core layer 211, a second absorbent core layer 212, and a third absorbent core layer 214. The first absorbent core layer 211 mainly absorbs liquid and absorbs the liquid into the second absorbent core layer 212. The surface of the first absorbent core layer 211 is designed for one-way absorption. The liquid is absorbed by the first absorbent core layer 211 from the upper layer to the lower layer and cannot return from the lower layer to the upper layer. After the first absorbent core layer 211 absorbs the liquid, the second absorbent core layer 212 stores the liquid. To prevent liquid from flowing out, the annular baffle 215 on the outer surface of the second layer 212 of the absorbent core serves as a structure to prevent liquid from flowing out. The third layer 214 of the absorbent core is the bottom layer of the new absorbent core 21. The third layer 214 of the absorbent core is not permeable, and liquid cannot pass through the third layer 214 of the absorbent core, thereby preventing liquid from flowing out of the third layer 214 of the absorbent core. The isolation pad 22 acts as a partition, and the isolation pad 22 is not permeable, thereby preventing liquid from passing through the isolation pad 22 and flowing into the sanitary napkin liner 11. In an emergency, the drawstring 213 is pulled out, and the new absorbent core 21 is pulled off through the drawstring 213, and the isolation pad 22 is also pulled off. After the new absorbent core 21 is pulled off, the emergency absorbent core 12 in the sanitary napkin liner 11 will be inflated and popped out to form a new emergency absorbent core 12, so that women can use the sanitary napkin body 1 for a second time in an emergency.
