Description

Three-dimensional gauze mask of high leakproofness

Technical Field

The utility model relates to the technical field of medical appliances, concretely relates to three-dimensional gauze mask of high leakproofness.

Background

The mask is mainly used for isolating harmful substances transmitted through gas, such as fine particles mainly containing PM2.5 and viruses transmitted in an aerosol state, and is generally classified into a flat mask and a three-dimensional mask. The three-dimensional mask, especially the three-dimensional mask with the filtering effect reaching 95 percent, is more conformable to the face, and has better filtering effect. Generally, the mask has a certain air leakage rate, the corners of the mouth, the chin and the sides of the bridge of the nose of the wearer are the main locations where leakage is likely to occur, and the discontinuity of the contact surface between these areas and the mask reduces the air tightness. One way to increase the airtight effect is to tighten the straps of the mask to seal the skin of the person's face, which makes the user uncomfortable to wear, and at the same time tightens the straps to make the parts other than the center of the mask stick to the face and lose the ventilation space, reducing the effective filtration area of the mask.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a simple structure, the high three-dimensional gauze mask of leakproofness.

In order to achieve the above object, the technical scheme of the utility model is to design a three-dimensional gauze mask of high leakproofness, including gauze mask body and face seal spare, face seal spare includes silica gel strip or the strip gasbag that sets up along the outer fringe of the medial surface of gauze mask body. The edge of gauze mask body medial surface sets up the facial sealing member of silica gel strip or strip gasbag, the silica gel strip of mild similar jelly form or the inflated strip gasbag is soft, it is inseparabler with the laminating of facial skin, need not too taut gauze mask frenulum, can reach sealedly with people's face skin, avoid too taut frenulum to make the gauze mask center with outside and facial laminating simultaneously, thereby lose ventilative space, the effective filtration area of gauze mask has been improved, ventilative space has been increased, the travelling comfort of wearing has been improved.

The preferred technical scheme is that the width of the silica gel strip is 0.5-0.8cm, and the thickness of the silica gel strip is 0.2-0.4 cm.

In order to further improve the sealing performance of the mask, the preferred technical scheme is that the inner side of the silica gel strip is provided with a long groove-shaped silica gel sucker along the length direction of the silica gel strip. Set up long recess form silica gel sucking disc, when tractive gauze mask frenulum, the silica gel sucking disc is hugged closely with facial skin absorption, has further improved the leakproofness at gauze mask edge.

In order to further improve the fit between the mask and the face, the preferred technical scheme is that the silica gel strip is cut into an adjustable circular ring shape. Gauze mask body edge sets up the annular silica gel strip of the ring that is cut into a plurality of sections, and the frenulum at the gauze mask body is taut back, and the sectional silica gel strip can be buckled along with the fluctuation of facial mouth nose, more laminates with face.

The preferred technical scheme is that the strip-shaped air bag is further provided with an inflation tube, the inflation tube is arranged below the mask body and penetrates through the mask body and protrudes out of the outer side face of the mask body, and a sealing cover is further arranged at an opening of the inflation tube.

The mask body comprises a left mask surface and a right mask surface, the left mask surface and the right mask surface comprise a first non-woven fabric layer, a polytetrafluoroethylene film layer, a polypropylene film layer and a second non-woven fabric layer which are sequentially stacked from outside to inside, the aperture of the polytetrafluoroethylene film layer is 0.15-0.2mm, and the thickness of the polytetrafluoroethylene film layer is 0.5-0.6 mm.

According to a further preferable technical scheme, a coarse filtering layer is further arranged between the first non-woven fabric layer and the polytetrafluoroethylene film layer.

The utility model has the advantages and the beneficial effects that: the high-tightness three-dimensional mask has the advantages of simple structure and high tightness; the edge of the inner side surface of the mask body is provided with the soft silica gel strip or the facial sealing piece of the strip-shaped air bag, the soft silica gel strip or the facial sealing piece of the strip-shaped air bag is tightly attached to the facial skin, the mask can be sealed with the facial skin without excessively tightening a mask tying belt, and meanwhile, the phenomenon that the center of the mask is attached to the face by the external part due to excessively tightening the tying belt is avoided, so that the ventilation space is lost, the effective filtering area of the mask is increased, the ventilation space is; the long groove-shaped silica gel sucker is arranged, when the lace of the mask is pulled, the silica gel sucker is closely attached to the skin of the face in an adsorption manner, and the sealing performance of the edge of the mask is further improved; gauze mask body edge sets up the silica gel strip that is cut into a plurality of sections, and after the frenulum of gauze mask body is taut, the silica gel strip of segmentation can be buckled along with the fluctuation of facial mouth nose, more laminates with face.
