2. The utility model discloses a sanitary pad, water conservancy diversion layer are bilayer structure from top to bottom, and upper and lower two-layer contact is connected and is equallyd divide cloth and have a plurality of water conservancy diversion through-holes, and upper and lower two-layer water conservancy diversion through-hole dislocation set owing to upper and lower two-layer for the contact connection can form certain gap between, absorbs liquid when sanitary pad uses, and liquid gets into the layer that absorbs water from upper and lower two-layer gap and water conservancy diversion through-hole, and upper and lower two-layer water conservancy diversion through-hole dislocation set can prevent liquid anti-infiltration simultaneously to the at utmost.

Drawings

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a top view of a sanitary pad according to an embodiment of the present invention;

fig. 2 is a cross-sectional view of a sanitary pad according to an embodiment of the present invention;

fig. 3 is a side view of a sanitary pad according to an embodiment of the present invention.

In the figure: the water-absorbing layer comprises a surface layer-1, a flow guide layer-2, a water absorbing layer-3, a hydrophobic layer-4, air holes-5, permeation holes-6, a hydrophobic non-woven fabric-7, flow blocking strips-8, flow guide through holes-9 and a release paper layer-10.

Detailed Description

Embodiments according to the present invention will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1-3, according to the utility model discloses a ventilative type sanitary pad with choked flow structure of embodiment, including the surface course 1 that from top to bottom sets gradually, water conservancy diversion layer 2, layer 3 and hydrophobic layer 4 absorb water, bleeder vent 5 has evenly been seted up to surface course 1, the diameter of bleeder vent 5 is 0.1-0.5mm, can keep the gas permeability of sanitary pad through bleeder vent 5, a plurality of infiltration holes 6 have evenly been seted up at the top of hydrophobic layer 4, the bottom of infiltration hole 6 is the enclosed construction, infiltration hole 6 can be used for storing the liquid that permeates into hydrophobic layer 4, surface course 1's surface is provided with one section hydrophobic non-woven fabrics 7 along central width direction symmetry, choked flow strip 8 is connected to the non-woven fabrics upper end, choked flow strip 8 is tensile elastomer, when using, thereby choked flow strip 8 is in tensile state extrusion non-woven fabrics in order to form one section choked flow structure in surface course 1 both sides, prevent the side leakage, when the sanitary pad does not use, the elastomer returns the balanced state and pulls up the non-woven fabrics simultaneously and forms choked flow barrier one, prevent reverse osmosis back side leakage.
