Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkins, in particular to a core structure with good air permeability. Background Art

[0002] Conventional sanitary napkins are generally three-piece integrated sanitary napkins, specifically sanitary napkin products in which a surface layer, a core, and a bottom film are integrally compounded.

[0003] The utility model patent with the publication number CN220025397U discloses a sanitary napkin with a suspended core structure. By arranging an I-shaped bonding part between the absorption core and the leakage-proof bottom film, the absorption core forms a suspended core structure. Since the absorption core is separated from the leakage-proof bottom film at the edge, during use, its edge can more effectively fit the skin, ensuring the comfort of the sanitary napkin, avoiding friction and preventing side leakage. However, during use, electrons will be generated due to friction, and when the number of electrons gradually accumulates, an electrostatic reaction will occur. Because the suspended core structure only contacts the body through the core, there will be conductive liquid remaining in the core contacting the body, and there is no carrier capable of accommodating electrons around it, so it is easy to accumulate on the surface of the suspended core. For this reason, we propose a core structure with good air permeability. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a core structure with good air permeability.

[0005] The technical solution adopted by the utility model to solve its technical problems is a core structure with good air permeability, including a core frame. A connection groove is opened in the central groove of the core frame, and a plug-in part is inserted into the connection groove. An air-permeable core is arranged at the center of the plug-in part;

[0006] A layer of air-permeable film layer is arranged on the surface of the air-permeable core. A layer of waterproof absorption layer is arranged at the bottom end of the air-permeable film layer. A layer of static protection layer is arranged at the bottom end of the waterproof absorption layer. A layer of absorption core is arranged at the center inside the air-permeable core at the bottom end of the static protection layer.

[0007] By adopting the above technical solution, during use, an electrostatic absorption structure is connected between the absorption core and the frame to transfer the electrons generated by friction between the skin and the core to the internal absorption core by means of electro-migration, thereby effectively reducing the occurrence of electrostatic reaction caused by long-term friction during the use of the core in the dry season.

[0008] Specifically, a leakage-proof layer is arranged at one end of the air-permeable core away from the air-permeable film layer.

[0009] By adopting the above technical solution, during the use process, the anti-leakage layer is used to prevent the absorbed liquid from leaking and soiling the clothing, and to prevent the electrons transferred into the liquid from escaping.

[0010] Specifically, an anti-static frame for facilitating assembly is arranged on the outer periphery of the plug-in part.

[0011] By adopting the above technical solution, the anti-static frame is used to transfer the electrons generated on the surface of the core body.

[0012] Specifically, two sides of the anti-static frame are fixedly connected with static adsorption flanks for anti-static, and the static adsorption flanks are inserted into the inside of the core frame.

[0013] By adopting the above technical solution, the static adsorption flanks are used to transfer the static electricity generated when the friction cloth rubs against the skin into the breathable core.

[0014] Specifically, a friction cloth for absorbing friction electrons is arranged on the surface of the core frame.

[0015] By adopting the above technical solution, the friction cloth and its unidirectional connection material are used to make the electrons generated by friction mainly generated in this area, and the electrons of the static electricity reaction are absorbed by the cloth of the anti-static frame into the breathable core, so as to avoid a large amount of electrons of the static electricity reaction generated by body movement from contacting the skin.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Through the structural design of the core frame, connection groove, plug-in part, anti-static frame, static adsorption flank, static protection layer, absorption core, friction cloth and anti-leakage layer in the technical solution of this application, an electrostatic absorption structure is connected between the absorption core and the frame. During the use process, the electrons generated by the friction between the skin and the core are transferred to the internal absorption core by means of electro-migration, thereby effectively reducing the occurrence of static electricity reaction caused by long-term friction during the use of the core in the dry season.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] Please refer to Figures 1-3 , an embodiment of the present utility model provides a technical solution: a core structure with good air permeability, including a core frame 1, a connection groove 2 is opened in the central groove of the core frame 1, a plug-in part 3 is inserted into the connection groove 2, and a breathable core 5 is arranged at the center of the plug-in part 3;

[0025] A breathable film layer 7 is arranged on the surface of the breathable core 5, a waterproof absorption layer 8 is arranged at the bottom end of the breathable film layer 7, an electrostatic protection layer 9 is arranged at the bottom end of the waterproof absorption layer 8, and an absorbent core 10 is arranged at the center inside the breathable core 5 at the bottom end of the electrostatic protection layer 9.

[0026] During use, an electrostatic absorption structure is connected between the absorbent core 10 and the frame, and during use, the electrons generated by friction between the skin and the core are transferred to the internal absorbent core 10 by means of electro-migration, thereby effectively reducing the occurrence of electrostatic reactions caused by long-term friction during the use of the core in the dry season.

[0027] As shown in the figure, a leakage prevention layer 12 is arranged at one end of the breathable core 5 away from the breathable film layer 7.

[0028] During use, the leakage prevention layer 12 is used to prevent the absorbed liquid from leaking during use, so as to prevent the clothes from being soiled and to prevent the electrons transferred to the liquid from escaping.

[0029] As shown in the figure, an antistatic frame 4 for facilitating assembly is arranged on the outer periphery of the plug-in part 3.

[0030] During use, the antistatic frame 4 is used to transfer the electrons generated on the surface of the core body.

[0031] As shown in the figure, electrostatic adsorption flanks 6 for antistatic are fixedly connected to both sides of the antistatic frame 4, and the electrostatic adsorption flanks 6 are inserted into the inside of the core frame 1.

[0032] During use, static electricity generated when the friction fabric 11 rubs against the skin is transferred to the breathable core 5 by electrostatically adsorbing the side wings 6.

[0033] As shown in the figure, a friction fabric 11 for absorbing friction electrons is provided on the surface of the core frame 1.

[0034] During use, the friction fabric 11 and its one-way connection material cause the electrons generated by friction to mainly be generated in this area, and the electrostatically conductive fabric of the anti-static frame 4 absorbs the static electricity electrons into the breathable core 5, preventing a large amount of static electricity electrons from coming into contact with the skin due to body movement.

[0035] The working principle and usage process of the present utility model: During use, the electrons generated by friction on the surfaces of the core frame 1 and the breathable core 5 are transferred to the electrostatic adsorption side wings 6 fixed to the side walls of the anti-static frame 4 through the anti-leakage layer 12. Since the core frame 1 transfers electrons by contacting the plug-in member 3 and the anti-static frame 4 through the connecting groove 2, and the absorption core 10 inside the breathable core 5 absorbs the electrons. At the same time, because liquid will be continuously absorbed during use, the overall electron concentration in the absorption core 10 will generally be maintained at a lower concentration than the surfaces of the core frame 1 and the anti-leakage layer 12. The electrostatic protection layer 9 and the friction fabric 11 are used to protect against the electron dissipation caused by liquid leakage. The breathable membrane layer 7 and the waterproof absorption layer 8 are used to protect the comfort when contacting the skin, and the core frame 1 is made of the same material as the breathable membrane layer 7 and the waterproof absorption layer 8, so as to maintain good air permeability between the core frames and improve the comfort.

[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
