Abstract

The present invention relates to a mask cover technology that is used by putting a cover on a mask which prevents fogging of glasses that occurs when wearing the mask in cold weather, prevents condensation inside the mask, and protects against cold. The present invention is composed of a cover outer skin, a cover inner skin, a nose clip, and an earring string outlet.

Description

mask cover {cover of mask}

It is a mask technology field that blocks the flow of humid air to the glasses due to exhalation through the pores of the mask to prevent fogging of glasses when wearing a mask in winter.

Due to COVID-19, yellow dust, and fine dust, masks have become routine and compulsory, and we have no choice but to use more in winter.

If you wear a mask in cold weather, the exhaled breath cannot be discharged powerfully far from the mouth and nose, which flows into the glasses and causes the glasses to fog up, causing severe inconvenience.

In order to solve this inconvenience, a cover is placed on the upper part of the mask to guide the exhalation to the lower part of the mask, and the exhalation from the uncovered part of the lower part has the effect of pushing in the chin direction. stop flowing into the glasses,

It prevents the mask and the skin around the mouth from getting wet due to condensation when the warm and humid breath inside the mask meets the cold air from the outside.

The background technology is to develop a mask cover that covers about 50% of the mask's outer skin area to obtain a cold protection effect that warmly protects the area around the mouth and chin.

20-0422159 for registration office (July 14, 2006) Mask with anti-fogging function of spectacle lens Patent Publication 10-2010-0017287 (2010.0.016) Maintenance-free anti-fog respirator Patent Publication 10-2020-0138653 (2020.12.10) Anti-fog mask

When wearing a mask in the cold winter, in order to prevent fogging of the glasses, it does not interfere with breathing and prevents warm and humid exhalation from flowing into the glasses. As the exhalation from the covered part is guided downward of the mask, even the exhalation from the uncovered part of the mask is pushed toward the chin, preventing fogging of the glasses,

When internal pressure due to exhalation in the mask occurs, the mask and the nose and face of the human body are in contact with the exhaled breath to prevent the fogging of the glasses,

The problem to be solved is to prevent the inner skin of the mask and the mouth and cheeks from becoming moist due to the occurrence of dew condensation when warm breath and cold air meet inside the mask.

A part of the upper part of the front of the mask is covered (covered) with a film (mask cover shell) to prevent the breath passing through the mask from flowing in the direction of the glasses and to flow to the bottom of the mask. When the outline of the endothelium coincides with sewing or welding, the mask is combined in the mask cover to create a guide groove that prevents it from being separated.

When the mask is inserted into the mask cover and combined, the top of the mask is closed, the bottom is open, and both sides are closed in close contact with the mask. The nose tip of the mask is not covered, and the exhalation from the covered part is guided by the cover, so that the flow path goes down to the open part of the mask, and the effect of pushing the exhalation from the uncovered part in the direction of the chin occurs. As it moves away from the direction, fogging of glasses does not occur.

The inner skin of the mask cover improves airtightness between the human body and the contact surface due to its thickness and elasticity, so that exhalation does not leak in the direction of the glasses.

By configuring the nose clip on the top of the endothelium of the mask cover, the contact surface between the nose and face is adjusted to fit the body shape to maintain airtightness of exhalation.

It has the effect of preventing fogging of glasses, preventing dew condensation in the mask, and protecting the face from cold.

Wearing a mask in cold weather causes fogging on the glasses and condensation inside the mask.

If you wear a KF94 mask or a dental mask to block infectious sources such as yellow dust, fine dust, and Corona 19, the cold protection function is poor.

It was devised for the purpose of developing a mask having the functions of preventing fogging of glasses, preventing condensation in the mask, and preventing cold, and it is possible to achieve the above purpose by covering the existing mask.

The top of the mask cover is closed and both sides are closed in close contact with the mask, and the bottom is open. Covers from the line connecting the bottom of both sides of the guide groove with the lower limit of the cover (hereinafter referred to as “the lower limit of the cover 150”) to the end of the upper end of the mask, and the exhalation-breathable cover shell that comes out of the covered part without being covered below the lower limit of the cover 150 Guided by (110), the flow path of the exhalation is downward toward the open part of the mask, so that the effect of pushing the exhalation from the uncovered part in the chin direction occurs, so that the breath moves away from the direction of the glasses.

The mask cover shell 110 is sewn or fused at the top and both sides of the top and both sides of the cover, and the outer part of the cover bottom 160 matches the end line with the cover endothelium 120. When the mask 200 is inserted into the mask cover endothelium, the mask cover 100 The mask does not come off from the mask cover, and the ear string outlet 140 of the mask is formed to draw the mask string out of the mask cover 100 to enable the mask to be worn.

The cover endothelium 120 is configured to have a minimum width that allows a guide groove to be created while following the outline combined with the cover shell 110 by sewing or fusion to block the pores of the mask so as not to cause breathing difficulties.

Non-woven fabrics, fibers, fabrics, etc. can be used for the mask cover outer skin and cover endothelium, and the nose clip 130 made of a flexible material is formed on the cover endothelium combined with the upper part of the mask to fit the nose part of the human body and the curved surface of the face. By adjusting it to fit closely, it prevents the breath from leaking in the direction of the glasses, and functions to additionally prevent the leaking phenomenon that was primarily prevented by the nose clip of the mask.

The cover endothelium 120 uses a resilient material that cannot be used as a mask material because it has a thickness, so that it has a function of improving the airtightness of the touch and the breath in contact with the skin.

The mask cover shell 110 covers more than the line connecting the nose tip of the mask and the lower ends of both sides of the guide groove so as not to cause an obstacle to breathing.

If the mask is classified according to its shape, it can be roughly divided into a three-layer mask consisting of the upper part, the front part, and the lower part, a bird beak-type mask in which the center line from the bridge of the nose to the chin is joined in an arc shape, and a pleated mask in which the left and right sides are parallel lines. Although the present invention can be designed to fit the shape, the upper and side surfaces of the mask are closed, and the cover sheath 110 that covers more than the cover lower line 150, the nose clip 130, the earring string outlet 140, the guide The groove and the open part are the same.

By making the cover area of the mask cover skin 50% of the mask outer skin area, the cold wind is covered, thereby reducing the dew condensation in the mask and providing an effect of cold protection.

When using a mask in winter and in cold regions, the inconvenience caused by fogging of glasses can be eliminated, and the number of people wearing glasses is on the rise. It is expected to develop into an industry that is positioned as a new product incidental to masks as it is expected to generate a lot of demand.
