DETAILED DESCRIPTION

[0019] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0020] like Figures 1 to 4 As shown, an antibacterial and odor-removing sanitary napkin comprises a sanitary napkin body 1, wherein the sanitary napkin body 1 comprises a surface layer 2, an absorption layer 3 and a leak-proof bottom layer 4 which are stacked in sequence from top to bottom along the thickness direction thereof, wherein the surface layer 2 is a double-layer structure, comprising a surface non-woven fabric layer 201 and an antibacterial layer 202 which are stacked from top to bottom, wherein the antibacterial layer 202 is composed of bamboo fibers, and a penetration hole 203 is pierced in the middle of the surface non-woven fabric layer 201, wherein the absorption layer 3 comprises an absorbent core 301 and a deodorizing layer 302 which surrounds the outer edge of the absorbent core 301, wherein the deodorizing layer 302 is filled with activated carbon, and an absorbent cotton strip 401 is arranged between the surface layer 2 and the leak-proof bottom layer 4 corresponding to the outer edge of the deodorizing layer 302, and side wings 101 which are integrally formed with the sanitary napkin body 1 are arranged on both sides of the sanitary napkin body 1.

[0021] like Figure 2 As shown, in terms of structure, the sanitary napkin body 1 of the utility model includes a surface layer 2, an absorbent layer 3 and a leak-proof bottom layer 4 which are stacked in sequence from top to bottom. The edge of the surface layer 2 is bonded and fixed to the edge of the leak-proof bottom layer 4 by the second adhesive layer 7, thereby forming an absorption chamber between the surface layer 2 and the leak-proof bottom layer 4. The middle part of the absorption chamber is provided with an absorbent core 301 bonded to the end surface of the leak-proof bottom layer 4. Liquid penetrates through the surface layer 2 and is absorbed by the absorbent core 301. The deodorizing layer 302 is provided around the outer edge of the absorbent core. When the liquid flows along the middle part of the absorbent core 301 toward the surroundings, it can be covered by the deodorizing layer 302, which has an all-round purification effect on the odor of the liquid and can greatly reduce the possibility of the odor being transmitted.

[0022] like Figure 3As shown, it should be noted that the surface layer 2 is a double-layer structure, including a surface non-woven fabric layer 201 and an antibacterial layer 202. The surface non-woven fabric is provided with a penetration hole 203 to prevent the double-layer surface layer 2 structure from affecting the penetration effect. The antibacterial layer 202 is a bamboo fiber layer, which has a natural antibacterial effect and can effectively inhibit the bacteria in the surface non-woven fabric and the absorbent core 301 bonded thereto. The deodorizing layer 302 is filled with activated carbon and has a good deodorizing function.

[0023] like Figure 2 As shown, it should be noted that the deodorizing layer 302 is formed by folding a single non-woven fabric toward the side away from the absorbent core 301, the deodorizing layer 302 is filled with activated carbon powder, and the opening formed by folding the outer side of the deodorizing layer 302 is fixed by glue, the inner side of the deodorizing layer 302 is attached to the outer edge of the absorbent core 301, and the inner edge of the deodorizing layer 302 close to the absorbent core 301 is not glued to avoid affecting the absorption performance of the absorbent core 301.

[0024] like Figure 3 As shown, further, in the above scheme, a first adhesive layer 6 is provided between the surface non-woven fabric layer 201 and the antibacterial layer 202, and the first adhesive layer 6 is arranged on the surface of the antibacterial layer 202 and close to the outer edge of the antibacterial layer 202, and the first adhesive layer 6 is filled with fabric fragrance microcapsules, and the fabric fragrance microcapsules are mixed with an adhesive to form a finishing agent, when subjected to external forces such as friction, slapping or rubbing, the microcapsules will be damaged, and the fragrance will overflow, thereby achieving a slow release of the fragrance, which has an inhibitory effect on odor when in use, and is not subjected to external forces when not in use, so that the fabric fragrance microcapsules will not be damaged, and the fragrance can be preserved for a long time.

[0025] Furthermore, in the above solution, the width dimension of the absorbent core 301 is smaller than the width dimension of the anti-leakage bottom layer 4 , and the length dimension of the absorbent core 301 is smaller than the length dimension of the anti-leakage bottom layer 4 .

[0026] Furthermore, in the above scheme, the width dimension of the surface layer 2 is the same as the width dimension of the anti-leakage bottom layer 4, the length dimension of the surface layer 2 is the same as the width dimension of the anti-leakage bottom layer 4, and a second adhesive layer 7 is provided between the edge of the bottom end surface of the surface layer 2 and the anti-leakage bottom layer 4.

[0027] Furthermore, in the above scheme, the bottom end face of the absorbent core 301 is bonded and fixed to the top end face of the leak-proof bottom layer 4, the inner side of the deodorizing layer 302 is abutted against the outer edge of the absorbent core 301, and the bottom end face is bonded and fixed to the top end face of the leak-proof bottom layer 4.

[0028] Furthermore, in the above scheme, the thickness dimension of the middle part of the absorption core 301 is smaller than the thickness dimension of the outer edge of the absorption core 301, thereby forming a concave area in the middle part of the absorption core 301 to prevent the liquid from flowing too quickly toward the outer edge of the absorption core 301 and failing to be absorbed in time. The thickness dimension of the deodorizing layer 302 is the same as the thickness dimension of the outer edge of the absorption core 301.

[0029] like Figure 2 As shown, it should be noted that a cavity 5 is formed between the bonding position between the surface layer 2 and the anti-leakage bottom layer 4 and the outer edge of the deodorizing layer 302, and the absorbent cotton strip 401 is inserted along the cavity 5. The thickness of the absorbent cotton strip 401 is not less than the thickness of the deodorizing layer 302. The absorbent cotton strip 401 plays a role in preventing side leakage. When liquid flows toward the absorbent core 301 and passes over the deodorizing layer 302, the absorbent cotton strip 401 absorbs the side leakage liquid to prevent the liquid from leaking along the edges of the surface layer 2 and the anti-leakage bottom layer 4.

[0030] like Figure 4 As shown, further, in the above scheme, the bottom end surface of the anti-leakage bottom layer 4 and the bottom end surface of the side wing 101 are provided with an integrated third adhesive layer 8, and a release paper 9 is provided below the third adhesive layer 8.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
