Compression spring 12 is located the surface of ear-hang belt 2, one side intercommunication that spunlace non-woven fabrics layer 7 was kept away from to dry piece 16 has connecting tube 22, connecting tube 22's other end intercommunication has anti-skidding gasbag 21, then when 15 volume enlargements of bellows bleed, gauze mask body 1 inboard hot steam enters into anti-skidding gasbag 21 along one-way air inlet 17 inside, anti-skidding gasbag 21 volume enlargement, anti-skidding gasbag 21 and the person's of wearing chin in close contact with, avoid when the person of wearing speaks, thereby the person of wearing chin constantly moves about and causes gauze mask body 1 and person of wearing chin to drop, reduce person of wearing's travelling comfort and security, increase person of wearing's the degree of difficulty.

One side that anti-skidding gasbag 21 kept away from gauze mask body 1 is equipped with the slipmat, and the slipmat contacts with the person's chin, can increase the frictional force of anti-skidding gasbag 21 and the person's chin with the help of the slipmat, and further increase anti-skidding performance of anti-skidding gasbag 21.

During the use, gauze mask body 1 is placed inside the gauze mask bag, because the elastic action of coupling spring 9 and compression spring 12, wedge 10 is located and holds 3 middle parts in chamber, connecting block 13 is located 11 middle parts in bottom chamber, both ends are located equally about the ear sling 2 this moment and hold chamber 3 and 11 insides in bottom chamber, and the ear sling 2 that is located gauze mask body 1 both sides all closely laminates in gauze mask body 1 both sides, then the gauze mask body 1 that is located gauze mask bag inside can not appear ear sling 2 twine and be difficult for dialling the condition of taking out and take place.

When taking out back from the gauze mask bag with gauze mask body 1, because bridge of the nose strip 4, fixed block 8 and dry piece 16 all can follow easy broken line 20 and take place to buckle, consequently open gauze mask body 1 both sides along easy broken line 20, and take 2 to both sides twitching with the ear-hang, this moment because the elastic coefficient of connecting spring 9 is less than compression spring 12, consequently the ear-hang takes 2 preferred pulling wedges 10 tensile connecting spring 9 to slide to the outside, wedge 10 can drive bridge of the nose strip 4 both sides through the wedge cooperation with bridge of the nose strip 4 when sliding to the outside and take place the bending along fixed block 8, consequently be convenient for wear gauze mask body 1 and can increase the degree of hugging closely of bridge of the nose strip 4 and the person's of wearing the nose.

After wear gauze mask body 1, hang 2 inside the ear of the wearer with the ear sling, and with bridge of the nose strip 4 laminating on the bridge of the nose of the wearer, anti-skidding gasbag 21 joint is at the downside of the chin of the wearer, and adjust the extension length of ear sling 2 according to the face type of the wearer, the length of 2 upper ends extensions in the ear sling is big more, the distance that wedge 10 removed to the outside in holding chamber 3 is big more, wedge 10 is big more with 4 wedge-shaped complex lengths of bridge of the nose strip this moment, bridge of the nose strip 4 is big more along the crooked degree of fixed block 8, bridge of the nose strip 4 is big more with the bridge of the nose laminating degree of the wearer, gauze mask body 1 wears the travelling comfort and the security performance is better.

After the wearing of the mask is finished, the wedge block 10 is in contact with the friction resistance of the nose bridge strip 4 for the elastic force of the connecting spring 9 cannot drive the wedge block 10 to move reversely, the extending length of the ear-hook belt 2 is just matched with the face shape of a wearer, and the nose bridge strip 4 and the anti-skidding air bag 21 are attached to the face of the wearer.

When a wearer speaks, because the mouth is opened, hot steam in the oral cavity of the wearer can be sprayed to the inner side of the mask body 1 along the mouth, particularly the hot air non-woven fabric layer 5, and when the wearer opens the mouth, the chin can move downwards so as to pull the lower end of the ear hanging belt 2 to move outwards, and the degree of outward stretching of the ear hanging belt 2 at the upper end of the mask body 1 is small.

When 2 upper ends in ear-hang area receive the lateral stretching, ear-hang area 2 can stimulate wedge 10 and remove to the outside, wedge 10 can stimulate connecting spring 9 simultaneously this moment and remove to the outside, but because the tensile force that 2 upper ends in ear-hang area received is less, then the degree that wedge 10 removed to the outside is less, and can further take place wedge sliding fit with nose bridge strip 4 when wedge 10 removed to the outside, thereby increase the laminating degree of nose bridge strip 4 to the wearer's face, guaranteed effectively when the lateral stretching in 2 upper ends in ear-hang area, nose bridge strip 4 can not take place to break away from with the wearer's nose bridge, it is especially, nose bridge strip 4 still can increase the laminating degree with the nose bridge, thereby avoid appearing the clearance between 1 top of gauze mask body and the nose bridge, lead to upwards discharging of steam and lead to the fact the interference to wearer's eyes, thereby cause the travelling comfort reduction of wearing.

By last, when the wearer speaks, the wearer's mouth is opened greatly downwards, consequently, 2 lower extremes of ear-hang belt receive outside tensile degree great, consequently, 2 lower extremes of ear-hang belt can drive connecting block 13 and extrude compression spring 12 and slide to the outside in end cavity 11, connecting block 13 can the other end pull rod 14 and remove this moment, tensile 14 can reverse pull 15 outside side movements of bellows, 15 increase in size of bellows this moment, then atmospheric pressure in the bellows 15 reduces, bellows 15 can play air exhaust effect to drying block 16, then inside mask body 1 because the hot steam that the wearer speaks and produce can follow one-way air inlet 17 and enter into inside drying block 16, and carry out drying dehumidification inside drying block 16, guarantee the drying nature and the travelling comfort of mask body 1 inboard.

The hot steam through 16 dry dehumidifications of drying block still can follow inside connecting channel 22 enters into anti-skidding gasbag 21, anti-skidding gasbag 21 increase in size, anti-skidding gasbag 21 can with the chin in close contact with of wearer this moment, consequently even the mouth opens greatly when the wearer speaks, 1 lower extreme of gauze mask body is because the joint effect of anti-skidding gasbag 21 and chin, make gauze mask body 1 can not take place to break away from with the wearer chin, it is especially, to the massage effect of wearer chin with the help of anti-skidding gasbag 21, can also improve the wearing comfort effectively, guarantee to wear for a long time and can not appear tightening, phenomenons such as drop.

When the person of wearing finishes the closed mouth of speaking, 1 upper end of gauze mask body can drive wedge 10 reverse movement normal position under the reverse elasticity effect of coupling spring 9, then wedge 10 can drive 2 upper ends reverse movement in ear sling and remove one section distances along holding chamber 3, wedge 10 and the reverse slip of wedge of bridge of the nose strip 4 this moment, consequently, the laminating degree of bridge of the nose strip 4 and the bridge of the nose reduces, 1 upper end of gauze mask body and the person of wearing face laminating degree reduce, improve the person of wearing comfort, avoid gauze mask body 1 too laminating to cause the person of wearing to breathe not smooth scheduling problem.

In the same way, 1 lower extreme of gauze mask body is under compression spring 12's reverse elasticity effect, connecting block 13 is in 11 internal antiport recovery normal positions of bottom chamber, then connecting block 13 can drive the lower extreme of ear-hang area 2 in 11 internal antiport of bottom chamber, 2 extension length in ear-hang area reduce, consequently the extension length adaptation wearer's of ear-hang area 2 facial form more, and can drive pull rod 14 and receive the pulling force reduction of outside removal during connecting block 13 antiport, then 15 antiport and volume of bellows reduce, 15 volume reductions of bellows can make its inside air and the gas of persisting in dry block 16 and anti-skidding gasbag 21 along one-way gas vent 18 discharges, no longer there is hot steam in dry block 16 this moment, anti-skidding gasbag 21 volume resumes normally and still laminates in the person's chin bottom.

Just so make each part all resume the normal position, consequently at the continuous in-process of speaking of wearer, the mouth of wearer constantly opens and closes, holds wedge 10 in the chamber 3 and constantly takes place to remove thereupon, and the pressfitting degree of wedge 10 and nose bridge strip 4 constantly changes to this adaptation is at the length change of the in-process ear sling 2 of wearer's speaking, and guarantee that nose bridge strip 4 is in the state of closely laminating constantly with the nose bridge, avoids causing droing of 1 upper portion of gauze mask body and nose bridge.

Similarly, when the wearer speaks, the mouth of the wearer continuously opens and closes, the jaw moving range is especially large, the connecting block 13 in the bottom cavity 11 moves with the connecting block, the connecting block 13 moves, the length of the ear hanging belt 2 can be properly adjusted, the change of the face shape length of the wearer during speaking is adaptively adjusted, meanwhile, the bellows 15 can be driven to continuously change the volume, so that the drying block 16 is exhausted and exhausted, hot steam in the inner side of the mask body 1 can enter the drying block 16 along the inner side of the mask body 1 for drying and dehumidifying, and can enter the anti-skid air bag 21 for increasing the volume, the anti-skid air bag 21 is always in a close fit state with the jaw of the wearer, the lower end of the mask body 1 is prevented from being separated from the jaw of the wearer, and finally the air in the drying block 16 and the anti-skid air bag 21 is exhausted along the one-way exhaust port 18, the integrity and the safety of the device are guaranteed, and the wearing comfort is improved.
