Description

MASK WITH FACE CONTACT FUNCTION

The present invention relates to a mask capable of continuously filtering air inhaled through the nose and mouth while stably covering the nose and mouth of a wearer, and more particularly, the mask body can be removed from the face regardless of the wearer's face structure and face size. It relates to a mask having a face-fitting function that allows a wearer to directly change the structure of the mask body so as not to be lifted.

In general, a mask refers to an object that covers a wearer's nose and mouth in order to prevent inhalation and scattering of germs and dust for hygiene reasons. These masks have been used since the outbreak of influenza, the Spanish cold, which was prevalent in 1919. When a person inhales cold air, the resistance in the nasal passages or oral cavity is lowered and the probability of infection with influenza is increased. . In the case of the first mask developed, it was possible to prevent cold air from entering the person's nasal passages or oral cavity, but it did not prevent influenza because it could not filter out viruses or bacteria contained in the air.

Since then, various technologies have been developed to develop a filter having an antibacterial function to filter out viruses or bacteria contained in the air, thereby preventing influenza. However, with the development of industry, there has been a problem of contamination of the environment such as air, water quality, and soil. the current situation.

As described above, since it is difficult to artificially remove contaminants such as fine dust already contained in the air, a technology for filtering contaminants contained in the air has also been developed. In particular, when a person engages in outdoor activities, he or she directly inhales contaminants such as fine dust, so a mask has been developed that can filter out contaminants with a filter while covering a person's nose and mouth.

A general mask includes a mask body that is seated on the wearer's face so that the inner side covers the nose and mouth of the wearer, and air flows in from the outside, and a hanging strap coupled to the left and right sides of the mask body and put over the wearer's ears is composed by That is, the hanging strap provides a function of preventing the mask body portion from being separated from the wearer's face while being caught on the wearer's ear. However, depending on the size of the wearer's face, the length of the hanger strap is short, and the mask body presses the wearer's face, making it inconvenient to wear. Since it is not in close contact with the wearer's face, external air is directly introduced into the wearer's nose and mouth.

In recent years, with the global outbreak of coronavirus (COVID-19), more than millions of masks are being used and thrown away every day.

In particular, in the manufacture of the electrostatic filter constituting the mask, the compressed polypropylene (PP) solution is sprayed with a high-temperature and high-pressure nozzle to which a high voltage (+) is applied. use the roux method.

The main body 11 may be formed in a multi-layer structure such as an internal filter, an intermediate filter, and an external filter. Such an inner filter, an outer filter, etc. may be composed of a non-woven fabric manufactured by melt-blowing processing or the like, or may be composed of a fiber having a structure in which cotton yarns are sandwiched with each other to form micropores.

The wrinkle portion 14 serves to increase the face cover area of the mask when in use.

The edge portion 12 is heat-sealed in a grounded state to be coupled to the body portion 11, and a metal wire 17 may be inserted so as not to be exposed to the outside. This wire 17 is to improve the anti-vibration effect by enhancing the adhesion when the mask 10 is worn, and is made of a plastic material such as metal that can be freely bent so as to adhere according to the curvature of the nose region.

The edge portion and the finishing portion may be made of a non-woven fabric made of a thermoplastic resin, and the ear string 15 may be attached to the body portion 11 by heat sealing through ultrasonic waves.

At this time, one end of the hook string 210 and 220 is interpolated to the front end of the hook string connecting rod 300 , and the other end of the hook string is interpolated to the rear end of the hook string connecting rod 300 . To this end, the hook string connecting rod 300 is formed with an interpolation passage through which the hook strings 210 and 220 can be interpolated therein along the longitudinal direction.

In addition, an opening through which the hook string is exposed to the outside may be provided in the insertion passage of the hook string connecting rod 300 . This is to expose one end of the hook string and the other end of the hook string that have passed through the internal insertion passage to the outside of the hook string connecting rod 300 . At this time, the wearer can adjust the length of the hanger strap surrounding the wearer's ear by pulling the end of the hanging strap exposed to the outside of the hanging strap connecting rod (300).

In addition, the inner diameter of the hanging string (210, 220) to have a reduced inner diameter than the outer diameter of the hook string (210, 220) so as not to be separated from the interpolation passage of the hook string connection rod 300 even if a pulling force is applied to the hook string after the ends of the hook string (210, 220) are interpolated. can be formed. In particular, the interpolation passage may be formed such that the inner diameter of the tip into which the ends of the hook strings 210 and 220 enter is the narrowest, and the inner diameter gradually widens along the longitudinal direction.

And the hook string connecting rod 300 may be provided with an incision line for interpolation of the hook string communicating with the interpolation passage along the longitudinal direction so that the ends of the hook strings 210 and 220 can be easily interpolated into the inner passage. At this time, the incision line for interpolation of the hanging string is provided in the opposite direction of the surface facing the mask body 100 as shown in FIG. it is preferable

As a third embodiment, the hook string connecting rod 300 according to the present invention may be configured to include a first hook string connecting rod and a second hanging string connecting rod that can be assembled or separated from each other.

The first hook string connecting rod is provided with a first interpolation passage through which one end of the hook string can be interpolated along the longitudinal direction so that the entire length of the hook string of the mask can be adjusted, and one end of the hook string is interpolated into the first interpolation passage. A first incision is provided in communication with the first internal insertion passage along the longitudinal direction so as to be able to do so, and a coupling protrusion is provided at the distal end. In addition, the first hook string connecting rod may be provided with a first opening in communication with the first interpolation passage so that one end of the hook string can be disposed outside after passing through the first hook string connecting rod.

The second hook string connecting rod is provided with a second interpolation passage through which the other end of the hook string can be interpolated along the longitudinal direction so that the entire length of the hook string of the mask can be adjusted, and the other end of the hook string is interpolated into the second interpolation passage. A second cut line communicating with the second internal insertion passage is provided along the longitudinal direction so as to be able to do this, and a coupling groove is provided at an end facing the first hook string connecting rod to be assembled with the coupling protrusion and connected thereto. In addition, the second hook string connecting rod may be provided with a second opening in communication with the second interpolation passage on the surface so that the other end of the hook string can be disposed outside after passing through the second hook string connecting rod.

Such a coupling protrusion may be formed of a cylinder, a square pillar, a square pillar, a pentagonal pillar, etc. to be interpolated into the coupling groove to be coupled, and the coupling groove may also be formed in a structure corresponding to the coupling protrusion so that the coupling protrusion can be interpolated. can

In particular, when the coupling protrusion is formed in a cylindrical structure, a screw thread may be formed on the surface of the coupling protrusion for solid coupling with the coupling groove, and a screw groove may be formed in the coupling groove.
