Detailed Description

Hereinafter, an anti-fog mask according to the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

The utility model provides an antifog gauze mask. In an exemplary embodiment of the anti-fog mask of the present invention, as shown in fig. 1, the anti-fog mask may include a mask body 1, a tightening band 2, and a shirred structure 3. Wherein, the tightening belts 2 are oppositely arranged at two side edges of the mask body 1. The pleated structure 3 is arranged on the upper part of the inner side surface of the mask surface body 1. The shirred structure 3 is formed by folding an antifogging layer. As shown in fig. 1, the folded pleated structure 3 is fixed in a long shape on the upper portion of the mask body 1. In the use state, the user can expand the shirred structure 3 downward and then attach the expanded shirred structure 3 to the face of the person or the mask body to prevent the rising of the exhaled hot air. For example, the user may stretch and expand the shirred structure 3 in the downward direction to fit the shirred structure 3 to the face above the nostrils or to fit the shirred structure 3 to the mask body 1. When attached to the mask body 1, the expanded lower edges of the shirred structures 3 are located above the positions of the nostrils with respect to the mask body 1. The fit can block exhaled hot air from rising along the mask at the shirred structure 3, and then prevent the eyes from fogging. The shirring structure 3 can stretch and expand according to different nose lengths of people, and has strong adaptability and good fitting comfort.

Further, as shown in fig. 1, the pleated structure 3 is provided symmetrically along the center line of the mask body 1 in the vertical direction.

Further, as shown in fig. 2, the shirred structure includes a fixing portion 301, a shirred portion 302, and an attaching portion 303. The fixing part 301 is provided on the inner side of the mask body for fixing the shirred structure to the mask body. The pleated portion 302 is provided between the fixing portion 301 and the attaching portion 303. The shirts 302 may expand in an up-down direction such that the shirts cover the face above the nostrils and below the upper edge of the shirts structure. The attaching portion 303 is provided at one end of the pleated portion 302. In the use state, as shown in fig. 2, the fixing portion 301, the pleated portion 302, and the attaching portion 303 are provided in this order from the top to the bottom. The cross-section of the shirred structure may be corrugated. The cross-section of the pleated portion 302 is shown in fig. 3, and the cross-section of the corrugated pleated structure exhibits a plurality of valleys 3001 and peaks 3002. Crest 3002 can laminate on people's the bridge of the nose, and a plurality of crests can shelter from the steam of human body exhalation layer upon layer, prevent that glasses from hazing.

Further, as shown in fig. 2, the length of the attaching portion 303 is larger than the length of the pleated portion 302 in the left-right direction. The length of the pleated portion 302 may be equal to the length of the fixing portion 301. Both ends of the attached portion 303 longer than the pleated portion 302 are equal, i.e., the first end 303a and the second end 303b are equal in length as in fig. 2. The first adhesive layer is provided on one side of the two ends of the adhesive portion 303 facing the mask body. The first pasting layer is used for fixing the antifogging layer on the mask surface body 1 in a folding mode and pasting the antifogging layer on the mask surface body 1 after the antifogging layer is expanded. The first adhesive layer can be one of solid glue, double-sided tape, nylon hasp and magic tape. The solid glue or double-sided glue may be a glue that is reused many times.

Further, the pleated portion 302 may be provided with flexible strips toward the left and right sides of the face to make the human body feel more comfortable when the pleated portion is fitted to the face.

Further, the fixing portion 301 may be formed of the same material as the pleated portion 302 and fixed to the mask body by punching. Of course, the fixing portion 301 may be fixed to the mask body by means of an adhesive or the like.

Further, the fixing portion 301 may be disposed at a position below the nose bridge of the mask.

Further, the thickness of the pleated portion 302 may be set according to the material to be made. To the better material of gas tightness, the thickness that can set up is 0.5mm ~2mm, is favorable to keeping breathing unobstructed like this and plays antifog effect simultaneously. For a mask with general air tightness, the thickness of the mask can be set to be 1.5 mm-2 cm.

Further, a second adhesive layer is disposed on the side of the adhesive portion 303 facing away from the mask body. The second adhesive layer is used for adhering to the face. The second adhesive layer can be adhered to the bridge of the nose, or the wings of the nose, or the bridge of the nose and the face near the bridge of the nose, or the wings and the face near the nose. The position where the second adhesive layer is adhered needs to be above the nostrils, so that the phenomenon that the nostrils are blocked by the anti-fog layer to cause unsmooth breathing is avoided. The second adhesive layer can be a silica gel layer with a thickness of 0.8 mm-1.2 mm. For example, the coating can also be one of medical nontoxic acrylic acid coating, medical nontoxic solvent glue and medical nontoxic water latex.

Further, as shown in fig. 3, the crests 3002 of the pleated structure, which is corrugated in cross section, are arranged in an arc shape. For example, a circular arc. Set up to curved crest, when draw the laminating of pleat portion on the bridge of the nose, can not produce strong oppression to the bridge of the nose and feel, make the laminating more comfortable.

Further, the antifogging layer may be obtained by a filter material having hydrophilic properties. The antifogging layer can be made of hydrophilic non-woven fabric, cotton cloth or hydrophilic fiber.

Further, the distance between the upper edge of the shirred structure and the upper edge of the mask body may be 15mm to 25mm, for example, 20 mm. The length of the pleated part can be 1/3-1/2 of the length of the mask surface body along the left-right direction. For example, 2/5 may be the length of the mask body.

The utility model discloses an antifog gauze mask is when the pleat structure is not expanded downwards, is applicable to equally not wearing users such as glasses, goggles and wears the use. When the user who wears glasses or goggles needs antifogging, will draw the pleat structure pull down suitable position, utilize the layer of pasting that the pleat structure set up to laminate antifogging layer on the face, then pinch the gauze mask bridge of the nose strip tightly, wear good gauze mask. The antifogging layer on the inner side surface of the mask surface body can well prevent the fogging of the lens caused by the exhaled hot air.

Although the present invention has been described above in connection with exemplary embodiments, it will be apparent to those skilled in the art that various modifications and changes may be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the invention as defined in the appended claims.
