[0002] As environmental awareness gradually increases, consumers' requirements for the environmental friendliness of daily necessities are also increasing. As a daily necessity for women, sanitary napkins are also widely concerned about their environmental friendliness. Traditional sanitary napkins are usually treated as solid waste after use, which not only occupies a large amount of landfill space, but also may cause potential pollution to the environment. Therefore, the development of a degradable and environmentally friendly sanitary napkin product has become an important development direction of the current industry.

[0003] Chinese patent announcement number: CN213641592U, discloses an environmentally friendly sanitary napkin, including a body, one end of the bottom film on the body is provided with a fixing belt for keeping the body in a curled state after the body is curled, and one end of the fixing belt is fixed on the bottom film; and also includes a sealing member for sealing the two ends of the body after the body is curled. After use, the patent can be curled into a roll, and the two ends can also be sealed. The dirt is wrapped inside, which slows down the growth of bacteria and improves the problem of dirty trash cans. However, after wrapping, it is still discarded as solid waste, which not only occupies a lot of landfill space, but also may cause potential pollution to the environment. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes an environmentally friendly water-soluble sanitary napkin, which solves the technical problems that the existing sanitary napkins are difficult to dissolve in water and have poor anti-leakage performance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An environmentally friendly water-soluble sanitary napkin comprises a sanitary napkin body, wherein the sanitary napkin body comprises a water-soluble non-woven fabric, a water-absorbing layer and a liquid-impermeable bottom layer stacked in sequence from top to bottom, wherein the water-absorbing layer comprises a first core body and two second core bodies arranged on the top of the first core body, wherein the second core bodies extend along the front and rear ends of the first core body, and the two second core bodies are respectively arranged on the left and right sides of the first core body, and flow blocking grooves are provided at the front and rear ends of the first core body.

[0007] Further:

[0008] A plurality of protrusions are arranged on the top of the liquid-impermeable bottom layer, and the protrusions are connected to the first core body.

[0009] The protrusion and the first core are connected by glue dispensing, and the glue dispensing adopts degradable and environmentally friendly hot melt glue.

[0010] The edges of the water-soluble nonwoven fabric and the liquid-impermeable bottom layer are formed into a plurality of connection points by heat pressing, and there are gaps between adjacent connection points.

[0011] The flow blocking groove is in a U-shaped structure.

[0012] A small envelope is arranged at the bottom of the liquid-impermeable bottom layer, and an opening is arranged on the small envelope. The sanitary napkin body can be stored in the small envelope after being rolled up.

[0013] The small envelope is a polyvinyl alcohol film.

[0014] A convex arc portion is provided on the top surface of the first core body, the arc portion extends along the front-rear direction of the first core body, and the arc portion is provided between the two second core bodies.

[0015] The water-soluble nonwoven fabric is provided with a plurality of rows of water holes in the horizontal direction or in the vertical direction.

[0016] Protection wings are symmetrically arranged on both sides of the middle part of the sanitary napkin body.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] The utility model arranges the second core body on the left and right sides of the first core body, which can prevent the side leakage of menstrual blood. Especially when lying on the side, the second core body forms a retaining wall, provides a more stable structural support, and prevents the menstrual blood from leaking from the thigh. The blocking groove is located at the front and rear ends of the first core body to guide the flow of menstrual blood, which can prevent the menstrual blood from leaking front and back. The connection surface between the second core body and the water-soluble non-woven fabric is small. During the water-soluble process, the flowing water enters the gap between the two second core bodies, which makes it easier to separate the second core body and the water-soluble non-woven fabric, greatly speeding up the dissolution speed, saving water, and being more environmentally friendly. Furthermore, the bulge is connected to the first core body to reduce The small contact surface makes it easier to separate the first core and the liquid-impermeable bottom layer during water dissolution; further, during water dissolution, water can flow into the water-absorbing layer from the gap at the connection point, thereby accelerating the overall water dissolution progress; further, the sanitary napkin is rolled up and then stored in a small envelope, which is cleaner and more convenient to dissolve; further, the polyvinyl alcohol film has good solubility; further, the raised arc-shaped portion fits the skin better, reducing displacement and sliding when worn; further, the water holes can not only accelerate the infiltration speed of menstrual blood, but also make it easier for water to enter the water-absorbing layer, thereby accelerating the water dissolution speed.
