[0027] In this embodiment, through holes are evenly arranged on the surface of the adsorption layer 10, and the through holes are in an inverted cone structure.
[0028] In this embodiment, U-shaped grooves are evenly arranged on the surface of the absorption layer 3, and mugwort leaves are installed in the U-shaped grooves.
[0029] In this embodiment, the first bonding sheet 2 is rectangular, and one end of the first bonding sheet 2 is connected to a first pull ring 7 .
[0030] Specific as Figure 1 , Figure 2 and Figure 3As shown, when this structure is used, the first pull ring 7 is used to tear open the absorption layer 10, and the menstrual blood is penetrated through the absorption layer 10 arranged on the surface of the surface layer 1. The inverted cone structure of the absorption layer 10 can accelerate the blood penetration, prevent backflow due to squeezing, and maintain the dryness of the absorption layer 10. At the same time, the sealed air cavity 11 can better make the two sides of the surface layer 1 fit the skin to avoid side leakage. The wormwood leaf arranged on the contact surface between the absorption layer 3 and the surface layer 1 can disinfect the surface layer 1 to avoid bacterial infection.
[0031] Embodiment 2: The backing sheets 6 are symmetrically arranged on both sides of the bottom layer 5 , and the second bonding sheet 14 is evenly arranged in the middle of the bottom layer 5 .
[0032] In this embodiment, the second bonding sheet 14 is V-shaped, and one end of the second bonding sheet 14 is connected to the second pull ring 15 .
[0033] In this embodiment, the outer wall of the water-absorbent sheet 12 is in contact with the inner wall of the anti-leakage layer 4 , and the outer wall of the water-absorbent sheet 12 is provided with liquid permeation holes 9 at equal intervals.
[0034] In this embodiment, the shape of the sealed air cavity 11 in a top view is a rectangle, and the shape of the cross section of the sealed air cavity 11 is an ellipse.
[0035] Specific as Figure 1 , Figure 3 and Figure 5 As shown, when this structure is used, menstrual blood penetrates into the absorbent sheet 12 through the absorbent layer 3, and quickly flows into the absorbent cavity 13 through the seepage holes 9. The waterproof film at the bottom of the leak-proof layer 4 is used to prevent leakage. At the same time, the bottom layer 5 is used to perform secondary leakage prevention on the menstrual blood inside the leak-proof layer 4. The back adhesive sheet 6 is turned over and torn off, the second pull ring 15 is torn off, the second bonding sheet 14 is exposed, the back adhesive sheet 6 is pasted on both sides of the clothing, and the bottom of the sanitary napkin is evenly pasted on the bottom of the clothing through the second bonding sheet 14. This structure can prevent seepage and greatly increase the degree of water absorption. At the same time, the sanitary napkin can be used without being displaced and affecting its use even if it is moved violently in time.
[0036] Working principle: firstly, tear open the first fitting sheet 2 through the first pull ring 7 to expose the adsorption layer 10, turn over the back adhesive sheet 6, pull open the second pull ring 15, and use the back adhesive sheet 6 and the second pull ring 15 to stick the bottom of the sanitary napkin to the bottom of the clothes. During use, the sanitary napkin can be better fitted to the skin through the sealed air cavity 11 to prevent side leakage of menstrual blood. At the same time, the menstrual blood is quickly converged to the surface of the absorbent sheet 12 through the adsorption layer 10, and the menstrual blood is quickly circulated to the inside of the leak-proof layer 4 by using the seepage holes 9 arranged on the surface of the absorbent sheet 12, so that the menstrual blood does not stay on the surface of the absorbent sheet 12, and the adsorption effect of the absorbent sheet 12 is not affected after the menstrual blood forms scabs, which can increase the amount of menstrual blood adsorption. At the same time, the wormwood placed in the U-shaped groove arranged on the surface of the absorption layer 3 is used to remove the odor of the adsorption layer 10, and the bottom layer 5 connected to the bottom of the leak-proof layer 4 is used to prevent the leak-proof layer 4 from seeping. The sanitary napkin can better fit the skin, prevent side leakage, and prevent the menstrual blood from forming scabs for too long, which affects the adsorption effect of the absorbent sheet 12 and causes leakage.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
