When the mask is used, the cool antifog nose bridge attachment strip is connected with the mask body of the mask in a hook and stick or gluing mode through the fixed attachment strip, so that the mask with the cool antifog nose bridge attachment strip is obtained, the hot air exhaled by a wearer can be effectively prevented from being discharged upwards, the antifogging capability of the mask is improved, and the stuffiness feeling of the wearer can be properly relieved.
Description
Technical Field
The utility model belongs to the technical field of the respiratory protection articles for use, relate to the gauze mask field, especially relate to a cool antifog bridge of nose strip and have cool gauze mask of feeling antifog bridge of nose strip.
Background
The novel coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) is called new coronavirus pneumonia for short, and the world health organization is named as '2019 coronavirus Disease', and is pneumonia caused by novel coronavirus infection. According to related reports, the novel coronavirus is a new type of human-borne virus, but the transmission path is not completely understood, and the known transmission paths include direct transmission (namely respiratory transmission), aerosol transmission and indirect contact transmission.
At present, with the importance of people on public health safety, more and more people choose to wear the mask in daily life, not only can prevent the inhalation of particulate matter in the air, can also carry out certain separation to microorganisms such as bacteria, virus in the air. However, the masks worn in daily life are only fit by a metal shaping strip, and close contact between both sides of the bridge of the nose and the masks cannot be ensured. When ambient temperature is lower, the steam of wearer's exhalation can rise to the wearer's eye through the space of nasal bridge both sides and cause discomfort, if the wearer still wears glasses simultaneously at this moment, the steam of wearer's exhalation can be on the lens liquefaction heat release production fog, seriously influences wearer's sight, has dangerous hidden danger. In general, wearers tend to reduce the gap on both sides of the bridge of the nose by pinching metal shaping strips or tightening straps of the mask, but this approach can create a feeling of stuffiness to the wearer.
In order to effectively prevent the hot air exhaled by the wearer from being discharged upwards and increase the anti-fogging capacity of the mask, the prior art discloses some anti-fogging masks and some anti-fogging nose pads. For example, CN206641412U discloses an anti-fog nose pad for a mask and an anti-fog mask, wherein the anti-fog nose pad comprises a nose pad body with an arc-shaped structure, the nose pad body is formed by curling an elastic sheet and has a first edge and a second edge, the first edge is used for being connected with the mask, and the middle position of the outer side of the nose pad body is recessed from the second edge towards the first edge to form a nose clamping position; the antifog nose pad further comprises a plurality of support parts protruding on the inner surface of the nose pad body, and the support parts are symmetrically arranged on two sides of the nose clamping position and used for supporting the cambered surface structure of the nose pad body. In the gauze mask use, antifog nose pad can closely laminate with user's bridge of the nose position to avoid the steam of user's exhalation to liquefy on the lens and release heat and produce fog, nevertheless antifog nose pad's structure is comparatively complicated, is unsuitable for using widely on a large scale.
CN210611089U discloses an anti-fogging nose pad, which comprises a nose-sticking part for sticking on the nose or nose surface of a human body, an extension part for guiding the air flow exhaled by the human body to the lower part, and a bending part for connecting the upper part of the nose-sticking part and the upper part of the extension part; the bottom of the nose pad is provided with a shaping strip; in the using state, the anti-fog nose pad is hung on the mouth mask. Antifog nose pad adopts designs such as flexion, extension, inclined plane to carry out the air current direction, is different from the formula design principle that blocks in the past, has effectively reduced the steam of the upflow of wearing person's exhalation to avoid the production of fog on the wearing person's eyeglass, nevertheless antifog nose pad makes inside gas of gauze mask and outside air be linked together, has seriously influenced the sealed effect of gauze mask, can't carry out the separation to microorganisms such as bacterium in the air, viruses.
CN206822037U discloses a three-dimensional mask with magic nose pad, the position detachably that is pressed close to with the bridge of the nose on the mask body is provided with magic nose pad, magic nose pad is including the elastic part that has certain elasticity and adaptation nose bridge shape and the magic subsides connecting portion of connecting elastic part detachable on the mask body. The magic nose pad can avoid the hot air exhaled by the user from liquefying on the spectacle lenses to release heat to generate fog, but does not relieve the stuffy feeling generated when the user wears the mask.
CN204888801U discloses an antifogging nose pad structure for reusable mask, which comprises an elastic pad, a reinforcing member and a release film, wherein the outer side of the elastic pad has a joint face, and the inner side of the elastic pad is formed with a positioning slot corresponding to the nose bridge of the user, and the elastic pad can move between a first operation position and a second operation position to make the positioning slot form match with the outline of the nose bridge of the user.
In summary, there is a need to develop a cool anti-fog nose bridge strip, so that the mask with the cool anti-fog nose bridge strip can effectively prevent hot air exhaled by the wearer from being discharged upwards, increase the anti-fog capability of the mask, and properly relieve the stuffy feeling of the wearer.
