AI Technical Summary

Technical Problem

Existing sanitary napkins are slow to remove mites, release antibacterial agents ineffectively, have difficulty removing odors, and are not very effective at preventing leaks. They are also prone to falling off and curling up, especially during exercise.

Method used

It adopts a combination design of three-claw anchoring wings, conductive mite-removing core, activated carbon fiber sheet and leak-proof edge. The conductive mite-removing core achieves rapid mite killing and sterilization through conductive carbon fiber mesh and tea tree essential oil microcapsules, the activated carbon fiber sheet absorbs odors, the leak-proof edge has strong dynamic adaptability, and the three-claw anchoring wings provide super strong fixing force.

Benefits of technology

It achieves rapid and effective killing of mites and bacteria, eliminates more than 85% of odors, ensures effective leak prevention in various body positions, provides super strong fixation, and avoids the problems of ineffective release and edge curling failure of traditional antibacterial agents.

Abstract

This utility model relates to the field of hygiene product technology, specifically an antibacterial and anti-mite self-cleaning sanitary napkin, comprising three-pronged anchoring wings. Two of the three-pronged anchoring wings are located on the left and right sides of an expanded cleanroom fabric wrapping layer. The bottom of the expanded cleanroom fabric wrapping layer has a breathable bottom layer, and the top of the breathable bottom layer has an expanded cleanroom fabric substrate. The top of the expanded cleanroom fabric substrate has a composite absorbent core, and the top of the composite absorbent core has a conductive anti-mite core. The top of the conductive anti-mite core has a three-dimensional flow-guiding surface layer. This improved sanitary napkin, through the intelligent response characteristics of the conductive anti-mite core, avoids the problem of ineffective release of antibacterial agents. The activated carbon fiber sheet can effectively absorb and lock in odor molecules, and the leak-proof edge ensures effective leak prevention during various body position changes. The triangular layout of the three circular rubber pads in the three-pronged anchoring wings enhances shear strength and provides superior fixation.
