Embodiment 1, as shown in figure 1, it is folded over filtering layer 02 inside edge strengthening area 03 on mouth mask 01, edge strengthening area There is ear-hang 04 on 03.The material of filtering layer 02 is folded over for single layer filter piece, or is compound including stenlizing layer, filter layer, lining etc. Layer filter, filtering monolithic or composite bed filter of the preferably haze filter, and thickness less than 2MM.

As shown in Fig. 2 filter layer laterally folded longitudinal arrangement successively, is folded over the filtering layer first floor and last layer reversed arrangement, mistake The first level 10 of filtering layer 11 laterally folds into the second aspect 08 successively, laterally folds into third layer face 14 successively；The first level 10th, the second aspect 08, the longitudinal arrangement of third layer face 14；The first floor of filter layer 11 is the first level 10 and last layer i.e. third layer face 14 Reversed arrangement, the first level 10 of the first floor extends to the right, and the third layer face 14 of last layer extends to the left.

It is folded over filtering layer inner side and is equipped with ventail, such as filter layer 11 is in the first level 10 and the second aspect 08 for folding Ventail 09 is laid in space；Filter layer 11 lays ventail in space of second aspect 08 with the third layer face 14 for folding 07；Above-mentioned ventail may be selected silk screen ventail, and preferably silk screen returns power ventail or ventilative sponge type silk screen returns power ventail.

Filter group 11 is folded successively for full wafer filter layer, or splicing folds connection, i.e. the first level 10 and second , in burst 12, the second aspect 08 and third layer face 14 in burst 05, two adjacent filter layers are welding or be bonded for aspect 08 Mode splices connection.

The filter process of air inlet has three aspect paths, such as：One, upper air is filtered through filter layer the first level 10, Silk screen ventail 09 is entered into, is gone out by ventilation mouth 06.Two, upper air, through silk screen ventail 07, is entered by ventilation mouth 13 Filtered to the second aspect of filter layer 08, by silk screen ventail 09, gone out by ventilation mouth 06.Three, upper air is by ventilative Mouth 13 is come in, and through silk screen ventail 07, is gone out after being filtered to filter layer third layer face 14.The overall mistake that filter layer 11 is folded successively Filtering layer participates in air filtration.Discharge gas process is with intake process conversely, not being expanded on further.

It is folded over filtering layer lower section and ventail 15 is set, ventail effect is to collect filter layer to cross air filtering, it is to avoid last layer mistake Filtering layer influences air filtration and collects after being contacted with face, it is monolithic silk screen ventail to be folded over filtering layer lower section ventail, also may be used Think that multi-disc silk screen is breathed freely pack.

Filter layer folded end is into space structure, such as its filter layer folded end of filter layer burst 05, filter layer burst 12 Into space structure, implementation is that silk screen ventail is close to filter layer folded end, supports filter layer folded end into sky for inside Between structure, such as one end of silk screen ventail 09 supports filter layer folded end into space structure, silk screen near filter layer burst 12 The one end of ventail 07 supports filter layer folded end into space structure near filter layer burst 05, and it is that distance is less than 1CM to be close to. Folded end space structure produces the filtering of filter layer eclipse effect to avoid adjacent filter layers at folded end.
