Embodiment a disposable mask

The embodiment discloses a disposable mask, as shown in fig. 1, comprising a mask body, two ear hanging ropes 10 and two side sealing strips 8. Wherein, the gauze mask body has business turn over gas fold portion 1, goes up fold sealing 2 and fold sealing 6 down, and two side sealing strips 8 are located the both sides of gauze mask body respectively, and is fixed with the gauze mask body through the mode of hot pressing, and every side sealing strip 8 extends to fold sealing 6 down by last fold sealing 2 along the width direction of gauze mask body. The air inlet and outlet folded part 1 is formed at the mouth and nose of a wearer, the upper folded sealing part 2 is formed at the upper end of the air inlet and outlet folded part 1 and used for isolating the position above the nose below the eyes from the outside, the lower folded sealing part 6 is formed at the lower end of the air inlet and outlet folded part 1 and used for covering and wrapping the chin below the mouth, and the nose sealing part 4 which is attached to the outer surface of the nose is formed in the middle of the upper folded sealing part 2. The mask body is composed of an outer non-woven fabric, a melt-blown fabric and an inner non-woven fabric which are sequentially laid from outside to inside, as shown in fig. 3, an air inlet and outlet fold part 1, an upper fold sealing part 2 and a lower fold sealing part 6 are formed by folding and folding the mask body, and a nose sealing part 4 is formed by placing the mask body after folding on a die and obtaining the mask body through shaping. In the preferred embodiment, the length of the inlet/outlet bellows 1 in the width direction of the mask body is d1=25mm, the lengths of the upper bellows seal portion 2 and the lower bellows seal portion 6 in the width direction of the mask body are both d2= d3=12.5mm, and the width of the mask body is d4=93 ± 2 mm. The principle of the embodiment is as follows: when a wearer hangs the two ear hanging ropes 10 on the two ears respectively, as shown in fig. 2, the sealing strips 8 on the two side surfaces are respectively attached to the side surfaces of the face, so that the mask body is sealed with the side surfaces of the face; after the air filter is worn, the air inlet and outlet folded parts 1 are not deformed, so that air enters the mouth and the nose through the air inlet and outlet folded parts 1, the air inlet and outlet folded parts 1 are in a folded state, and the air filtering effect of the air inlet and outlet folded parts on the passing air is improved; the nose sealing part 4 is attached to the outer surface of the nose of a wearer, and the nose sealing part 4 moves up and down along the face by pulling the upper fold sealing part 2 according to the shape and size of the nose of the wearer, so that the nose sealing part 4 is suitable for different wearers, and the upper part of the mask body is sealed with the face; the lower wrinkle sealing part 6 is pulled to wrap the chin of the lower wrinkle sealing part 6, so that the lower part of the mask body is sealed with the face. Therefore, the mask body is isolated from the outside through the side sealing strips 8, the nose sealing part 4 and the lower folding sealing part 6, the wearer exchanges gas with the outside through the air inlet and outlet folding part 1, sealing of the aluminum strip is replaced, the process of fixing the aluminum strip is omitted, and after the mask body is used, the mask body is processed in the form of medical waste, so that waste of the aluminum material is saved.

The nose sealing part 4 of the present embodiment preferably includes shaping strips 5 disposed on the upper folded sealing part 2 and located at two sides of the nose, and the upper folded sealing part 2 located between the two shaping strips 5 has a curved surface adapted to an outer surface of the nose. The specific manufacturing process comprises the steps of placing the mask body on a die, fixing the thermoplastic polyethylene strip on the mask body by the shaping strips 5 in a hot-pressing mode, so that the two shaping strips 5 are positioned on two sides of the nose, and the mask body between the two shaping strips 5 is matched with the outer surface of the nose. If the wearer wears back nasal part sealing 4 and has gapped the nasal part surface, realize that nasal part sealing 4 reciprocates through drawing last fold sealing 2 to realize that nasal part sealing 4 and nasal part are laminated mutually. Be equipped with horizontal nose bridge strip 11 in the gauze mask body between two moulding strips 5, this nose bridge strip 11 can buckle, and its effect is with the horizontal driving fit of bridge of the nose for nose department fully keeps apart with the external world.

The fixing mode of the hangers 10 of this embodiment is that, on the air inlet and outlet folded part 1 and on one side of the side seal strip 8 far from the other side seal strip 8, the heat pressing limit point 9 is provided, the hangers 10 penetrate into the outer non-woven fabric and penetrate out, and the position where the hangers 10 penetrate is the gap between the side seal strip 8 and the corresponding limit point 9.

In order to improve the adhesion between the side sealing strip 8 and the side of the face and improve the sealing performance, as shown in fig. 1, the middle portion of the side sealing strip 8 extends inward along the length direction of the mask body, and the angle between the connecting lines of the two ends and the middle portion of the side sealing strip 8 is 168 °, and the preferred angle is 161 °.

In order to improve the sealing between the upper folding seal part 2 and the lower folding seal part 6 and the face, as shown in fig. 1, at least one upper sealing strip 3 is hot-pressed on the upper part of the upper folding seal part 2, and each upper sealing strip 3 extends from one side of the mask body to the other end of the mask body along the length direction of the mask body; at least one lower sealing strip 7 is hot-pressed on the lower portion of the lower fold sealing portion 6, and each lower sealing strip 7 extends to the other end of the mask body from one side of the mask body along the length direction of the mask body. When the upper sealing strips 3 are more than two, the distance between the adjacent upper sealing strips 3 is 8mm, and when the lower sealing strips 7 are more than two, the distance between the adjacent lower sealing strips 7 is 5 mm. Wherein, the upper sealing strip 3 and the lower sealing strip 7 are fixed on the mask body in a hot-pressing manner, and the upper sealing strip 3 and the lower sealing strip 7 have another function of sealing the edge of the mask body.

The manufacturing processes of the upper sealing strip 3, the lower sealing strip 7, the shaping strip 5 and the side sealing strip 8 are all formed by shaping the mask body by adopting an ultrasonic heat sealing process, and logo, trademark and the like on the mask body are also formed by hot pressing through the ultrasonic heat sealing process. Wherein, the other effect of top seal strip 3, bottom seal strip 7 and side sealing strip 8 is to carry out the banding with the gauze mask body to avoid constituting the outer non-woven fabrics of gauze mask body, melt and spout cloth and interior non-woven fabrics and taking place the cluster when wearing, and do not play the function of impurity in the filtered air.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the protection of the claims of the present invention.
