Description

Transparent type face mask with large volume of ventilation

The present invention is a transparent mask capable of recognizing a face, combined with a frame structure equipped with a pleated filter structure to purify external and internal air, so that the ventilation amount is increased by at least 2 times or up to 25 times compared to the effective ventilation amount of the existing mask. It relates to a transparent mask having a large-capacity ventilation, characterized in that.

A mask is worn to block pathogens transmitted through the respiratory tract. Such a mask is generally a filter structure in the form of a fiber aggregate, and the structure itself is an opaque fibrous tissue.

These masks become a mask structure that covers the face when worn on the face, so there are many inconveniences when face-to-face such as interpersonal relationships and airport immigration, and safety issues such as crime prevention occur.

When humans breathe, they inhale oxygen and exhale carbon dioxide through the two nostrils of their nose. When a mask is used, this carbon dioxide is not expelled, but remains in the mask and re-breathing, so the oxygen supply decreases and the carbon dioxide intake increases, which causes diseases of the respiratory system. However, if the cotton tissue is expanded to increase the airflow, it is difficult to obtain a quarantine effect by reducing the capture of pathogens.

In addition, the size of the conventional woven mask of fibrous tissue is usually 18cmX9cm=162cm² in width × length. However, among these mask areas, the breathing area (G) through which air passes for breathing is about 6cmX6cm=36cm² of the portion from the nose to the bottom of the mouth as shown in the reference diagram of FIG.

In this way, only about 1/4 of the total mask area acts as a ventilation filter, and the rest of the majority area is used as a function to block the inflow of external air by adhering to the area around the mask and the skin of the user's face.

In addition, since these masks are disposable, a large amount of waste is generated every day, and waste of resources is also emerging as a serious problem.

Republic of Korea Patent Application 10-2017-7008797 The sanitary mask structure is a mask that recognizes a user's face through a through hole regularly formed in the fiber layer by woven optical fiber. Due to the characteristics of these masks, there is a limit to the user's face recognition due to the mesh-like transmittance, and as a disposable mask for quarantine that collects pathogenic viruses, the manufacturing cost is high and the manufacturing process is very complicated, so there is a limit in application.

Therefore, if the numerical aperture of the weave is increased to increase the user's air intake/discharge amount, the prevention effect is lowered, and if the numerical aperture of the weaving is reduced, the user's face recognition is blocked.

Korean Patent Application No. 10-2014-0027510, Korean Patent Application No. 10-2010-0101511, Korean Patent Application No. 10-2014-0070910

It is a simple anti-splash blocking structure that prevents splashing when cooking food, but has a different purpose and configuration from the present invention, and cannot be used for quarantine hygiene to block fine dust and viruses.

In addition, in existing masks, the exhaust air that the user exhales from the nostrils wraps around the entire face and is discharged through the mask, so the temperature inside the mask rises as much as possible, increasing discomfort in hot seasons and places such as summer.

Therefore, when composed of a transparent mask, the amount of ventilation is low, which causes respiratory diseases. When using an opaque mask, it is possible to increase the amount of ventilation, but breathing is insufficient and the user's face recognition is blocked.

Korean Patent Application 10-2017-7008797 Korean Patent Application 10-2014-0027510 Korean Patent Application 10-2010-0101511 Korean Patent Application 10-2014-0070910

An object of the present invention is to provide a structure of a transparent mask that allows the maximum ventilation effect in the minimum mask member filter area with the amount of air breathing and discharged by the filter while transparently recognizing the user's face.

The pleated filter, which is mounted on the filter mounting part and performs an air purification function, is configured as a separate unit so that it is separated and combined with the filter mounting part, so that it can be used for one-time use or separated and replaced at any time.

The external air vented through the pleated filter is vented to the inner surface of the transparent mask through the filter mounting unit from the outside, and the user's air is discharged from the inner surface of the transparent mask through the pleated filter and discharged to the outside.

The material of the transparent mask is made of a material with good transparency and good moldability such as pp, urethane, and PET silicone with a transmittance of 60% or more.

According to the present invention, since the frame structure is configured in the body and various filters such as an air filter can be used and exchanged as needed in the filter mounting part provided on the inner surface of the frame, the entire mask structure can be used repeatedly.

The transparent mask structure that covers the user's nose, mouth, and chin can clearly recognize the user's face, thus solving the problem of the conventional mask of the mask structure that covers the face.

Since the filter structure provided in the pleated shape can obtain the same ventilation effect with an area of 1/4 compared to the conventional one, the ventilation amount is increased 4 times and the pleated filter 12 inside the frame 11 can be provided with the largest area. The city can expand the ventilation effect up to 25 times.

That is, the structure of the present invention as described above is a transparent mask structure that recognizes the user's eyes, nose, mouth, and mouth shape, and has the effect of increasing the effective ventilation amount by 2 times or more to 25 times compared to the conventional mask. Difficulty breathing and breathing discomfort caused by the mask can be relieved.

The terms and figures used in the present invention describe examples and do not limit the present invention. In the specification, the singular includes the plural unless otherwise specified. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The overall shape of the present invention consists of a frame 11 and a transparent mask 21 as shown in FIGS. make up

If described in more detail with reference to Fig. 5 (a), the transparent mask 21 has a structure that covers the upper part of the nose (H) of the user 40 and is composed of an inclined surface (H), but is transparent above the height (H) of the nose After forming the inner (e) height of the mask 21, the inner (e) space of the transparent mask 21 was formed by forming a vertical plane (I) from the nose tip and mouth position of the user 40 to the height of the nose. It is formed in the form of a cover that covers up to the position of the chin of the next user (40).

The vertical surface (I) is formed in the form of a lower inclined surface (K) close to a right angle in the inner direction at the user's 40's chin position, and the frame 11 is formed on this lower inclined surface (K) in the horizontal direction, and then inside It constitutes the filter mounting part (12).

The structure of the inclined surface (H), the vertical surface (I), the lower inclined surface (K), and the frame 11 is not limited to a straight line and may be configured in various shapes depending on the design, such as a curved, curved, or spherical shape.

The structure of the frame 11 is composed of a filter mounting unit 12 that is opened in both up and down directions, and a pleated filter 31 that is mounted on and separated from the filter mounting unit 12, but is configured separately.

In more detail, as shown in FIGS. 1, 3, and 4 (a) and 4 (b), the present invention is worn on the user's face and is curved left and right along the lower part of the user's face. The frame 11 ) and a part of the frame 11 are configured to open up and down, and the frame 11 is configured on the front side of the frame 11 and the filter mounting part 12, so that the frame 11 is formed with an inclined surface close to a right angle shape based on the transparent mask 21. .

The lower part composed of such an inclined surface becomes the outside (f) of the transparent mask 21 and

The upper portion of the rectangular shape becomes the inner surface (e) of the transparent mask (21).

In other words, the present invention is provided with a filter mounting part 12 that is open to both top and bottom inside the frame 11 formed at an inclination angle inward compared to the transparent mask 21, and a fold in which air is vented up and down. A filter (31) is provided. Accordingly, the lower portion of the filter mounting portion 12 is opened to the outside (f), and the upper portion is opened to the inner surface (e) of the transparent mask 21 .

It is composed of a transparent mask 21 through which the user's face is transparently transmitted, and air blocking films 15 and 22 provided around the transparent mask 21 and in the portion where the user's face touches the frame 11 to block the flow of external air. and

It is mounted on the filter mounting unit 12 and has a pleated function to purify air and prevent pathogens, and consists of a filter unit 30 configured as a separate unit so that the pleated filter 31 is separated from and combined with the filter mounting unit 12 .

The material of the transparent mask 21 is made of a material such as PP, urethane, and PET silicone, such as PP, urethane, and PET silicone, that has good moldability and transmittance of 60% or more, as shown in FIGS.

The entire periphery of the transparent mask 21 and the part in contact with the user's skin among the inner parts of the frame 11 are closed with a soft finishing frame 22 to block the inflow of external air into the mask.

1 and 3, the structure of the hook 14 to be hung on the user's ear has one side on both ends of the frame 11 and one side on both ends of the transparent mask 21, so that the transparent mask 21 and the frame 11 structure are used. makes it more stable and closely adheres to the user's face.

Also, as shown in Fig. 1, an embossed surface 23 is formed in the area in contact with the facial skin of the user 40 in a part of the inner part of the transparent mask 21 to prevent the transparent mask 21 from being adsorbed to the skin.

In addition, the inner surface of the transparent mask 21 may be additionally coated to prevent fogging.

The transparent mask 21 has a transmittance function such as a glass window, and its transmittance is at least 60% or more, and preferably 80%-90% or more, so that the user's eyes, nose, and mouth can clearly recognize even the mouth shape and expression during conversation. .

The present invention is further configured so that the frame 11 itself is bent left and right on the left and right sides of the frame 11 as shown in FIG. 1 so that the frame 11 and the transparent mask 21 are in close contact with the user's face. In this configuration, the frame 11 itself has a transparent mask 21 and a hook 14 connected to the frame 11 to both ends of the filter mounting unit 12 inside the frame 11, and the air barrier 15 structure is It has the effect of making it closely adhere to the user's face.

As such, external air such as oxygen passing through the pleated filter 31 configured in the frame 11 is wrinkled provided in the frame 11 as shown in FIGS. 1, 2 (b), and 4 (b). Air, such as carbon dioxide, which is introduced into the inner space (e) of the transparent mask 21 through the filter 31 and discharged by the user is discharged from the inner space (e) to the outer space (f) in the reverse order.

That is, in the present invention, the inflow of external air is blocked by the air barrier 15 provided around the transparent mask 21 and inside the frame 11, and only the pleated filter 31 is sucked in and discharged.

An object of the present invention is to configure a filter for realizing an abundant amount of ventilation while configuring the transparent mask 21 . Therefore, the configuration of the air purification filter as shown in FIG. 2 is important.

That is, in the present invention, since only the area in front of the nose, which is only 1/4 or 5 of the total mask member area in the conventional mask structure, has a ventilation function, and the remaining part is used as a structure to block the inflow of external air, resource waste and ventilation efficiency are very low, but the present invention By using the entire mask member as a ventilation function, the ventilation efficiency can be increased by more than 2 times to 25 times, thereby increasing the respiration rate and remarkably reducing the waste of the mask member.

To explain in more detail, as shown in FIGS. 1 and 3, the filter mounting part 12 is formed inside the frame 11 and provided with a pleated filter 31 therein, but this pleated filter 31 is for one-time use. Therefore, it is configured to be mounted and separated from the filter mounting part (12).

The size of the filter mounting part 12 is selected according to the intended use of the present invention, and a pleated filter 31 is provided therein for use.

For sports, the respiration rate increases, so a pleated filter 31 with a large ventilation amount is mounted, and for general use, the size of the pleated filter 31 with an appropriate ventilation amount is determined and appropriately provided.

2 (a) and (b) are explanatory views of the pleated filter 31 mounted on the filter mounting part 12,

As for the material of the filter, various existing antibacterial and fabric mask materials are used as filter materials, but they are used in the form of a filter with folds.

The pleated filter 31 has a larger amount of ventilation due to its pleats than a conventional general mask.

In more detail, as shown in Fig. 4 (b), the height of the user's nose is about 2 cm based on the adult, so the height of the inner space (e) in front of the transparent mask 21 is about 3-4 cm based on the user's nose. it is appropriate

The length from the user's lower lip to the chin is about 3-4 cm, and if the frame 11 is formed in a circle along the user's face, the length can be up to 20-22 cm.

When the weight of the frame 11 itself increases, a pull-up 17 structure may be added to the lower portion of the frame 11 for user convenience as shown in FIG. 1 .

Therefore, the maximum size of the frame 11 including the filter mounting unit 12 provided with the filter 31 inside the transparent mask 11 is 3 cm from the height of the user's nose to 3 cm from the lips to the chin according to the user's face. The inner length of the frame 11 formed by bending in the left and right directions is 20 cm. That is, the maximum size of the filter mounting portion 12 to which the pleated filter 31 is mounted is 3 cm in width × 3 cm in height × 20 cm in length.

In addition, if the size of the user's mouth is assumed to be 5 cm in width and 2 cm in height and 2 cm in width for the purpose of using this mask, the minimum size of the filter mounting part 12 inside the frame is 2 cm × 2.5 cm × 5 cm.

The shape of the filter mounted on the filter mounting part 12 is configured in a pleated shape in which a triangular shape overlaps as shown in (a) and (b) of FIG. 2 .

The interval (c) between the triangular filter pleats is appropriate to be 2-5 mm, assuming that the thickness of the pleated filter 31 material is 0.5 mm as shown in FIG. 2(a).

Therefore, the maximum size of the filter mounting part 12 is 3 cm in width × 3 cm in height × 20 cm in length. The triangular pleated filter 31 has a width (a) 3 cm, a height (b) 3 cm, a triangle as shown in FIG. If the internal spacing of (c) is 2mm, 100 pieces are composed of the length (d) of 20cm (200mm). That is, the total area of the triangular pleated filter 31 required for this is 3cm wide × (3cmX100 pieces) = 900cm²

This will have a large-capacity ventilation amount of about 25 times compared to the effective ventilation area of 36cm² of the existing mask.

Therefore, according to the same logic, the minimum size of the filter mounting unit 12 is a triangular pleated filter 31 mounted on a width of 2 cm × height of 2,5 cm × length of 5 cm, as shown in FIG. (b) ;2,5CM, the inner spacing of the triangle (c) is 3mm, the length (d) is 5cm (50mm), and 16,6 pieces are composed. That is, the total area of the triangular pleated filter 31 required for this is 2cm wide × (2,5cmX16.6 pieces) = 83cm².

This will have more than twice the amount of ventilation compared to the effective ventilation area of 36cm² of the existing mask.

In addition, the size of the existing mask is 18cm x 9cm = 162cm². The material area of about 1/2 of the total area of such a conventional mask will have twice the amount of ventilation.

Therefore, the maximum effective ventilation area of the present invention has an effective ventilation area of at least twice or at most about 25 times compared to the effective ventilation area (G) 36cm² of the conventional mask of FIG. 6 .

Based on the total area of these existing masks, the middle size of the frame 11 of the present invention is 2.5 cm in width, 2.5 cm in height, and 3 mm in the distance (C) of triangular folds (2.5X2.5X26 = 162.5cm²) 26 pieces in length Wrinkles are made up.

As described above, the ventilation effect of 162.5cm² of the present invention composed of the triangular pleated filter has a ventilation effect of about 4,5 times compared to the effective ventilation area (G) 36cm² of the existing mask.

In this embodiment, when the pleated filter 31 is configured with the same area as that of a conventional mask, the ventilation amount is about 4,5 times. This results in the same ventilation effect as only 1/4 or 5 of the members of the conventional mask.

Conventional quarantine masks are recommended to be used once a day and cannot be recycled and are discarded as waste. Accordingly, the structure of the present invention reduces the required amount of the conventional mask member to 1/4.

Therefore, since the structure of the present invention can be implemented as described above, the performance of the present invention can be expanded from 2 times or more to a maximum of 25 times compared to the conventional general mask.

The structure of the pleated filter 31 and the shape of the filter mounting part 12 for mounting the pleated filter 31 may be configured in a curved shape such as a circle or a half-moon shape.

The structure of FIG. 3 is configured with the same logic as the structure of FIG. 1 . As shown in Fig. 4(b), the entire transparent mask 21 covers from the upper part of the nose to the lower chin of the user, and the frame 11 is provided between the user's mouth and the chin inside the transparent mask 21, and this frame ( 11) is a structure in which the filter mounting part 12 and the transparent mask 21 are combined, and its function and compositional effect are the same as in FIG. 1 .

1, 2, and 3 of the present invention, which is configured as such, the pleated filter 31 is located directly under the nostril of the user 40 as shown in FIG. rises

That is, as the air circulates to the outer space (f) through the pleated filter 31 of the filter mounting part 12 through the user's lower nose space as shown in FIG. It is used only as a function.

As shown in (a) of Figure 4 (b), the present invention is clearly and transparently presented to the user's eyes, nose, and mouth through the transparent mask ( ) 21 .

The inner surface of the transparent mask 21 is coated with an anti-fogging coating caused by the user's breath so that the user's face is always transparent.

The frame 11 and the filter mounting unit 12 provided in the frame 11 may be formed outside the frame 11 within a range that does not cover the user's eyes, nose, and mouth.

In addition, in the case of Figure 1, both ends of the frame 11 can be further configured with a rotary folding device 18 on both sides of the frame 11 on the left and right so that both ends of the frame 11 can be gently and elastically bent to the left and right so that it can be in close contact with the user's face. However, when the frame 11 structure is composed of a soft transparent soft structure such as PP, urethane, or silicone, the folding device 18 may be deleted.

In addition, an ultraviolet lamp 9 is further provided on one side of the filter mounting part 12 to sterilize the ventilated air.

The present invention configures the straw hole 42 in the transparent mask 21 with an aperture through which the straw 41 can pass so that the beverage can be drunk through the straw as shown in FIG. 5 (b).

That is, a straw hole 42 through which the straw 41 can be inserted is formed at the upper portion of the frame 11 at the user's mouth position, and an elastic cover 42 is formed inside the transparent mask 21 so that the user wants to drink a drink. When inserting the straw 41 into the straw hole 42, the cover 43 opens and when the straw 41 is removed, the cover 43 covers the straw hole 42 by its elasticity.

In addition, the present invention connects the air hose 45 to one side of the frame 11 or the transparent mask 21, that is, to a position that does not cover the user's face, as shown in Fig. 5 (c), and a filter 31a is added. A fan 44 is provided to suck in the air inside the transparent mask 21 and discharge it through the filter 31a, so that the facial temperature inside the transparent mask 21 can be adjusted.

In this configuration, the filter 31a is separately configured to be separately mounted and separated, and the air intake fan 44 structure can be combined with the transparent mask 21 itself by removing the air hose 45.

The carbon dioxide emission device discharged by the user in the transparent mask 21 sucks the air inside the transparent mask 21, purifies it with the filter 31a, and then discharges it. It reduces the accumulation of the virus and prevents the external air leakage of the virus.

In addition, as shown in Fig. 5 (d), a microphone 13 is provided on one side of the transparent mask 21 on one side or on one side of the frame 11 that does not cover the face of the user 40, so that an external smart phone, etc. Alternatively, it can be used in connection with the miniature amplifier 46 .

The configuration of the microphone 13 is unclear due to the air blocking film 22 configured around the transparent mask 11 of the present invention, so that the inconvenience during face-to-face meetings or meetings can be eliminated.

In addition, a functional filter 32 such as a filter having a deodorizing function for removing bad breath may be additionally mounted to the frame mounting unit 12 as shown in FIG. 2(b).

In addition, the position of the structure of the frame 11 having the filter mounting part 12 is configured to be located at the user's lower mouth and chin, thereby making it possible to configure the entire upper part of the frame transparently.

Therefore, the structure of the present invention allows the user's eyes, nose, and mouth to be transparently recognized as they are, the shape of the mouth and the facial expression when speaking.

Another effect of the configuration of the position of the frame 11 is to configure it under the nostril through which the user breathes. The position of this frame places the pleated filter 31 at the shortest distance from the user's nostril while exposing the shape of the user's mouth. Therefore, it is possible to minimize the increase in temperature inside the mask because the time for exhausting the air by the user is shortened.

In addition, the present invention can increase the user's oxygen respiration rate and sufficiently discharge carbon dioxide by sufficiently expanding the ventilation amount by the area of the pleats of the pleated filter, so that breathing discomfort, difficulty breathing, respiratory disease prevention and mouth In addition to reducing odor, it is possible to obtain innovative effects that cannot be considered in the conventional transparent mask structure, such as being able to be worn during sports activities.
