Description

The mask of filtering layer is folded in the same direction

Technical field

It the utility model is related to mask, more particularly to a kind of mask for being folded over filtering layer in the same direction.

Background technology

There are air pollution, it is necessary to which people wear mask protection health, in mask use in the environment of people's life In, common mask gas permeability is bad, particularly plane type mask of the haze impurity screening rate more than more than 90%, and filters Air is only limitted to oral area and nasal region, and ventilation area is small, and uses hemisphere cup-shaped mask unsightly, to people it is daily leave or Activity is made troubles.

The content of the invention

The utility model aim is in order to make up for the deficiencies of the prior art, there is provided the mask of filtering layer is folded in the same direction, it is horizontal The filter layer for being folded into three layers to arrangement has two groups to five groups to be arranged in order, and an at least adjacent sets are folded over filtering layer group Foldable square phase Together, it is folded on the inside of filtering layer and is equipped with ventilation strip, filter layer folded end two sides integral sealing.The effectively filtering aspect of increase mask Product, so as to increase gas permeability and service life.

The technical solution adopted in the utility model is as follows：

Transversely arranged two groups to five groups of the filtering layer that is folded over into three layers is arranged in order, at least adjacent one group of filter layer Foldable square To identical, adjacent folds filtering interlamellar spacing is more than 3MM, is folded over filtering layer inner side and is equipped with ventilation strip, it is whole to be folded over filtering layer two sides Body seals.

Further, each group filter layer folding direction is identical, and it is silk screen ventail to be folded over the ventilation strip on the inside of filtering layer.

Further, it is folded over below filtering layer and is laid with ventail.

Further, each group filter layer folding direction is identical, is folded on the inside of filtering layer and is equipped with supporting rack bar or supporting point block Group, supports adjacent filter layers into ventilation strip.

Further, adjacent filter layers are laid with ventail into being folded over below filtering layer for ventilation strip.

Further, filter layer is single layer filter layer or multiple layers of filters pack, is folded into bending fold or splicing folding Folded, filter layer is folded into the overall folding successively of filter layer or filter layer locally folds successively.

The beneficial effects of the utility model are：Simple structure, increases filter effective area twice than common plane face mask Left and right, so as to increase gas permeability, improves comfort level.

Embodiment

Embodiment 1, as shown in Figure 1, transversely arranged is folded over three groups of filtering layer, folding direction is collectively aligned, i.e. from filtering Layer head end 01 arrives filter layer end 14, and filter layer folding group 03, filter layer folding group 04, filter layer folding group 11 3 are laterally arranged Row filter layer folding direction is identical.It is that filter layer first layer 10 is folded back the second layer to be folded over 11 foldable structure of filtering layer group Face 08, folds into third layer face 07 before the filter layer second layer 08.

Ventilation strip is equipped with the inside of adjacent folds filter layer, such as filter layer the first level 10 with the second aspect 08 of folding Ventilation strip 09 is laid with space；The second aspect of filter layer 08 in the space in the third layer face 07 folded with being laid with ventilation strip 12, thoroughly The preferred silk screen ventail of gas bar or ventilative sponge type silk screen return power ventail.

Exemplified by 3rd filter layer group 11, air realized that air filtering had three aspect paths by filter layer：One, upper air Filtered through filtering layer the first level 10, enter ventilation strip 09, gone out by ventilation mouth 05.Two, upper air passes through ventilative Mouth 13, through ventilation strip 12, enters the second aspect of filter layer 08 and filters, by ventilation strip 09, gone out by ventilation mouth 06.Three, on Square air is come in by ventilation mouth 13, through ventilation strip 12, is gone out after being filtered to filter layer third layer face 07.It is folded over filtering layer group 11 Each layer filter layer participates in air filtration.Gas process is discharged with intake process on the contrary, not being expanded on further.

It is folded over below filtering layer and ventail 02 is set, ventail effect is to collect filter layer to cross air filtering, avoids filter layer Air filtration is influenced after being contacted with face and is collected, it is Monolithic breathable piece to be folded over ventail below filtering layer, or multi-disc Ventilative pack.

Filter group folds successively for full wafer filter layer, or splicing folds connection, such as the second aspect 08 and third layer 06 at folding, two adjacent filter layers splice connection in a manner of welding or be bonded etc. in face 07.

It is folded over filtering layer group to be arranged in order, spacing, which is more than 3M, between each group prevents filter layer eclipse effect from using, and such as filters Distance is more than 3MM between layer group 03, filter layer group 04,10 adjacent filter layers group of filter layer group.

As shown in Fig. 2, being folded over filtering layer group 11, be folded over filtering layer group 04, be folded over filtering layer group 03 on side on mask 15 Inside edge stabilization zone 16, there is ear-hang 17 in edge strengthening area 16.It is single layer filter piece to be folded over 02 material of filtering layer, or is to include killing The composite bed filter of bacterium layer, filter layer, lining etc., preferably haze filter.

As shown in figure 3, being folded over the edge sealing processing of filtering layer folded end two sides, that is, it is folded over 16 two sides of filtering layer, side envelope Mouthful place 15 and side sealing part 17 progress the mode Seal treatment such as welded seal or adhering and sealing, air is passed through filtering layer 16 Filtered, prevent air being folded over escape at filtering layer two sides, filter layer is lost using effect.

Supporting rack air guide can be set in adjacent folds filter layer, adjacent two filter layer is supported, make inside adjacent two filter layer For ventilation strip layer, as shown in figure 4, being folded over inside adjacent the first filter layer 20 and the second filter layer 21 of filtering layer 22, set The supporting racks such as supporting rack 18, supporting rack 19, support adjacent filter layers, make breathable and air guide inside adjacent two filter layer, Gas between adjacent two filter layer can flow.

As shown in figure 5, the supporting rack on filter layer is the point branch such as block, i.e., supporting rack 18, supporting rack 19 on filter layer 21 Support is supporting point block group.

As shown in fig. 6, the supporting rack on filter layer is support bar, i.e., on filter layer 21, the branch such as support bar 21, support bar 22 Stay, the ventilative support bar of two support bars.

The utility model, which is applicable in, is not limited to filter layer plane face mask, is also suitable solid type mask, is set in the utility model Meter can increase bridge of the nose folder, mask strengthened edge area lower section sets elastic sealing strip, vent valve, coarse filtration floor, liner etc. common auxiliary Component is helped, is added within scope of protection of the utility model in the annex on the basis of the design.
