Description

Antifogging nose pad

Technical Field

The utility model relates to a protective articles technical field, concretely relates to antifog gas nose pad that gauze mask was used.

Background

The new coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) is called new coronavirus pneumonia for short, and is pneumonia caused by 2019 new coronavirus infection, which is known to be highly infectious since the Disease is caused in 2019.

Experts point out that the main infection routes of COVID-19 are droplet infection, contact infection, aerosol infection and the like. Masks may be used for personal protection to reduce the risk of infection. The mask is a sanitary article, is worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to achieve the purpose of preventing harmful gas, smell, spray and the like from entering and exiting the mouth and nose of a wearer. The mask has a good effect when the respiratory infectious disease is epidemic and the mask is worn when the mask is operated in the environment polluted by dust and the like. Particularly in the fields of medical care, health and epidemic prevention, the mask is a protective measure which is regularly used during working. However, people who wear glasses, goggles, masks and the like often touch the situation that the lenses are fogged when the mask is worn for expiration, the sight line is influenced, and much inconvenience is brought to life and work. The main reason for analysis is that the mask and the nasal part and the facial tissues around the nose cannot form good air tightness, gas can be upwards blown out from gaps during exhalation, and fog can be generated when the mask meets a lens with relatively low temperature. Although a moldable material such as iron wire is used at about 0.5cm from the upper edge of the mask, such as a surgical mask, to increase the fit with the nose, the problem of fogging of the expiratory glasses cannot be avoided.

On the one hand, in view of the existing solutions, the mask is designed, for example, an exhalation valve device is added, so that although the problem of a gas discharge channel is well solved, the mask is not beneficial to disease propagation prevention, and the mask manufacturing difficulty and cost are increased; on the other hand, starting from the mask accessories, an antifogging nose pad design is reported ([ CN201520535216.8] reusable antifogging nose pad structure of the mask), but similar designs mostly increase the attaching area by the contour fluctuation shape of the nose and the nose circumference designed on the nose pad in advance to improve the air tightness, but the sealing effect is greatly reduced due to the large difference between the individual nasal face morphology of people, and the design is mainly adhered to the upper end of the inner side of the mask by adhesive materials such as double-sided adhesive tapes and the like, so that repeated use is not facilitated for many times, and the adhesion effect under the influence of aerosol also has problems; there are also reports ([ CN206641412U ] anti-fog nose pad and anti-fog mask for mask) that the nose pad is detachably connected to the mask to solve the problem of adhesion between the nose pad and the mask, but the nose pad is attached to the nose by filling materials with deformability such as silica gel, and the nose pad is separated from the nose face due to the weight of silica gel when the person lowers his head to do various operations; in summary, none of these solutions generally addresses the problem of eyewear fogging during exhalation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an antifog gas nose pad that gauze mask was used to solve gauze mask and nasal part and nose week facial tissue can't form good gas tightness, can cause gaseous upwards scurries out and causes glasses fog and influence the problem of sight when exhaling under various circumstances such as look down with low head overlooking.

In order to achieve the above object, the utility model provides an antifog nose pad, it contains: the nose-sticking part is used for sticking to the nose or the nose surface of a human body, the extension part is used for guiding airflow exhaled by the human body to the lower part, and the bending part is used 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 nose pad is hung on the mouth mask; wherein, the nose pasting part is arranged at the inner side of the mask; the side, close to the mask, of the nose attaching part is a near mask side, the lower part of the nose attaching part is wedge-shaped, and the near mask side of the lower part of the nose attaching part is provided with an inclined plane which inclines from the mask to the direction of the nose; the bending part is wrapped on the upper edge of the mask; the extension part is arranged on the outer side of the mask and extends downwards.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

In the present invention, terms relating to the orientation, such as upper portion, lower portion, bottom portion, upper edge, upper end, lower end, height, etc., are described in the orientation in the use state, and are not intended to limit the structure.

As shown in fig. 1, is a schematic structural view of the anti-fog nose pad of the present invention. The utility model discloses an antifog gas nose pad 1 contains: the nose-sticking part 15 is used for being stuck on the nose or the nose face part of a human body, the extension part 12 is used for guiding the air flow exhaled by the human body to the lower part, and the bending part 11 is used for connecting the upper part of the nose-sticking part 15 and the upper part of the extension part 12. The bottom of the nose pad 1 is provided with a shaping strip 14. As shown in fig. 2, it is a schematic view of the usage status of the anti-fog nose pad 1 of the present invention. In the using state, the nose pad 1 is hung on the mask 2 through a groove formed on the inner side of the bending part 11. Wherein, the nose pasting part 15 is arranged at the inner side of the mask 2; one side of the nose attaching part 15 close to the mask 2 is a near mask side, the lower part of the nose attaching part 15 is wedge-shaped, and the near mask side of the lower part of the nose attaching part 15 is provided with an inclined plane 13 which inclines from the mask 2 to the nose direction; the bending part 11 wraps the upper edge of the mask 2, and the extension part 12 is provided on the outer side of the mask 2 and extends downward.

When the nose pad 1 of the utility model is used, the nose pad 1 and the mask 2 are worn together. The bent part 11 is free from the restriction of sliding up and down, left and right of the upper edge of the mask 2, and the upper edge of the mask 2 can freely slide in the range of the groove formed by the bent part 11. The utility model discloses a nose pad 1 independent existence, use with 2 cooperations of gauze mask, do not influence the original design of gauze mask, can supply to wear groups such as glasses, goggles as required to select to purchase alone.

In some embodiments, the shaping strip 14 is a wire/strip. The bottom of the nose attaching part 15 is provided with a metal wire/strip and other plastic materials, the shape and the extrusion degree of the nose can be adjusted by a wearer, the attaching effect of the nose pad 1 is improved by utilizing the deformability of the metal wire/strip, the air tightness reduction caused by the influence of the difference between individuals when the nose and the contour relief shape around the nose are designed on the nose pad in advance is avoided, and the stable retention and the nose anti-moving effect can be obtained by the attaching and extrusion adjustment of the nose.

The utility model discloses a set up extension 12 and prevent that the gauze mask from deviating from flexion 11 to guide gas 3 downwards. As shown in fig. 3, the utility model discloses an attached in human nasal part or nose face portion back of nose pad 1, the recess that upwards gas 3 leads to the flexion 11 formation through inclined plane 13 when will exhaling, the passageway discharges between gauze mask 2 and nose pad extension 12 after the turn, meets the glasses that the temperature is lower relatively after having avoided hot gas 3 to flee upwards when exhaling, produces the fog on the lens of messenger's glasses and influences the problem of sight. The inclined plane 13 arranged on the near-mask side of the nose pad 1 is matched with the groove to better guide the exhaled air 3 out.
