It is an air flow diagram showing the air flow when the mask exhales.

As shown in Fig. 1, the mask 10 on which the open filter according to the embodiment of the present invention is formed includes a main body part 100, a ventilation part 200, a sub-body part 300, and a spacer 400. Include.

More specifically, as shown in FIGS. 1 and 2, the mask 10 on which the open filter according to the embodiment of the present invention is formed is attached with a filter that covers the user's face to block the inflow of fine dust, It includes a main body portion 100 is formed at least one or more through-holes 110 passing through.

The ventilation part 200 is formed corresponding to the position of the through hole, and may be used for opening and closing the main body part 100.

The sub-body part 300 is spaced apart from the outer surface of the main body part 100 to form an inner space 201. The sub-body part 300 is an optional component of the mask 10 and is a sub-body part ( It is also possible to configure the mask 10 without 300).

When the mask 10 includes the sub-body part 300, the separation part 400 is a main body so that the outer surface of the main body part 100 and the inner surface of the sub-body part 300 are separated from each other. It may protrude from the outer surface of the body part 100.

Referring to FIG. 2, the main body part 100 is made of a non-woven fabric or synthetic fiber that blocks fine particles and dust contaminated in the environment, and consists of a filter and a solid frame supporting the same.

In addition, the main body unit 100 will be described in detail with reference to the accompanying drawings, preferred embodiments in which a person of ordinary skill in the art to which the present invention pertains can easily implement the present invention. However, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In addition, the main body portion 100 is formed with at least one or more through-holes 110.

Here, the through hole 110 is formed through one surface of the main body 100 so that the air of exhalation is quickly discharged to the outside while blocking the inflow of external fine dust during inhalation and exhalation, and a ventilation unit (to be described later) ( 200) are combined.

2 and 3, the ventilation part 200 is formed corresponding to the position of the through hole 110 and serves to open and close the main body part 100.

To this end, the ventilation unit 200 includes a body filter 210, a ventilation frame 220, a first magnet unit 230 and a second magnet unit 240.

The body filter 210 is made of a nonwoven fabric or synthetic fiber filter, and is formed wider than the width of the through hole 110.

That is, the main body filter 210 is formed in a plate shape wider than the through hole 110, but the upper portion is integrally coupled with the main body portion 100. Accordingly, it acts as a gate to close or open the through hole 110 according to the user's inhalation and exhalation.

Accordingly, the main filter 210 is rotated around the position of the upper portion of the ventilation frame 220 so as to be spaced apart from the ventilation frame 220 when exhaling.

Ventilation frame 220 is sealed along the edge of the through hole 110 to form a frame shape. This serves as a frame for the through hole 110 and seals the rim to prevent the filter of the main body 100 from being torn or damaged.

Here, it is preferable that the ventilation frame 220 is formed on the surface of a silicone or soft material so as to increase adhesion to the main filter 210.

At least one first magnet part 230 is formed by being attached to one side of the main filter 210. The first magnet part 230 contacts the second magnet part 240 when power is applied to the second magnet part 240 to be described later to form a magnetic force, so that the main filter 210 passes through the through hole 110. It serves to close it.

And as another example, when the first magnet part 230 changes the polarity state of the second magnet part 240 so that power is applied to the second magnet part 240 to form a magnetic force, the main filter 210 is pushed open. .

The second magnet part 240 is buried in the ventilation frame 220 corresponding to the first magnet part 230 and receives electric power to form a magnetic force.

In particular, one side of the second magnet part 240 is exposed to the outer surface of the ventilation frame 220 and the other side is buried inside the main body part 100. Further, it is connected to the sensing unit 250 to be described later, and a magnetic force is formed in response to the user's inhalation and exhalation, thereby controlling the rotational motion of the main filter 210.

In addition, the second magnet part 240 may be buried in the ventilation frame 220 corresponding to the first magnet part 230 to generate magnetic force.

That is, the second magnet part 240 does not generate magnetic force by electricity, and may be replaced with a configuration in which magnetic force is generated by itself, such as a permanent magnet, so that it may contact the first magnet part 230.

The ventilation part 200 further includes a third magnet part (not shown) in a plate shape.

The third magnet unit (not shown) is disposed between the first magnet unit 230 and the second magnet unit 240 and serves to adjust the magnetic force therebetween.

That is, the third magnet part adjusts the magnetic force by adjusting the overlapping area between the first magnet part 230 and the second magnet part 240. In addition, it compensates for the occurrence of a difference in the positive internal pressure of the main body unit 100 due to the difference in the user's exhalation, thereby helping to smoothly breathe in even when the situation changes such as individual differences or external wind.

Meanwhile, as shown in FIGS. 3 and 4, the mask 10 on which the open filter according to the exemplary embodiment of the present invention is formed further includes a sensing unit 250.

The sensing unit 250 senses the pressure generated when the exhaled air is filled inside the main body unit 100 and recognizes it as exhalation, and controls the power applied to the second magnet unit 240 to control the main body filter 100. Plays a role in opening up.

To this end, the sensing unit 250 includes a sensing electrode 251, a metal plate 252 and a light-receiving unit 253.

The sensing electrode 251 is formed with a circuit electrically connected to the second magnet part 240.

This sensing electrode 251 is connected to the sensor 251a and the CPU 251b.

The sensor 251a is connected to a metal plate 252 to be described later to detect inhalation and exhalation. In addition, the sensor 251a serves to open the main filter 210 by controlling the power of the second magnet unit 240 when exhaling.

The CPU 251b converts and stores the pattern of breathing into data through the sensor 251a, and controls the sensor 251a.

In particular, the CPU (251b) receives the inhalation and exhalation detection signals of the sensor 251a according to the section in which breathing is accelerated or slowed, and resets the section in which the main filter 210 may be opened to set the opening/closing timing. Accordingly, when the main body filter 210 is separated from the ventilation frame 220 by controlling the power applied to close the through hole 110, the user can breathe smoothly and prevent the occurrence of difficulty in breathing.

The metal plate 252 is capable of representing a change in the electrical resistance 252a or the capacitor 252b in response to inhalation and exhalation. Accordingly, the operation of the sensing unit 250 becomes smooth.

In addition, in the mask 10 on which the open filter is formed according to an embodiment of the present invention, a battery may be formed to operate the sensing unit 250. Although not shown in the drawings of the specification, a battery for driving the sensing unit 250 and the second magnet unit 240 is formed, and the battery may be rechargeable or exchangeable.

The light-receiving unit 253 allows the change of light to be displayed in response to inhalation and exhalation. Due to this, the operation of the sensing unit 250 is smoothed by detecting a change in respiration.

2 and 3, the sub-body part 300 is disposed to be spaced apart from the outer surface of the main body part 100, and forms an inner space 201.

That is, the subbody part 300 provides an outer shell made of a material having excellent breathability while having a design element so as to have an aesthetic feeling by covering the exterior of the mask.

The sub-body part 300 forms an inner space 201 by a spacer 400 to be described later so that there is no resistance to the movement of the main filter 210 that opens and closes the through hole 110.

2 and 5, the spacing part 400 is of the main body part 100 so that the outer surface of the main body part 100 and the inner surface of the sub-body part 300 are separated from each other. It is formed protruding from the outer surface.

In the mask 10 on which the open filter is formed according to the embodiment of the present invention, as shown in FIG. 5, the sub-body part 300 is in close contact with the outer surface of the main body part 100.

In addition, when exhaling, the sensing unit 250 senses the pressure of the air formed inside the main body unit 100 and controls the power applied to the second magnet unit 240 so that the main body filter 210 is It is spaced apart from 220 to open the through hole 110.

At this time, the air remaining inside the main body part 100 is discharged through the through hole 110 and moves to the inner space 201. In addition, the air that has moved to the internal space moves to the outside of the subbody unit 300 to facilitate the user's exhalation.

FIG. 11 is an air flow diagram showing air flow during exhalation and inhalation of a mask with an open filter according to an embodiment of the present invention, and FIG. 12 is a frame of a mask with an open filter according to an embodiment of the present invention An exemplary diagram showing a modified portion and a support portion, and FIG. 13 is an exemplary diagram showing a subbody portion and a spacer portion further formed on a mask having an open filter according to an embodiment of the present invention.

As shown in FIGS. 6 and 7, the mask 1010 on which the open filter according to another embodiment of the present invention is formed includes a body part 1100, a ventilation part 1200, a frame part 1300, and a support part 1400. Includes.

7 and 8, the body portion 1100 is made of a non-woven fabric or synthetic fiber that blocks fine particles and dust contaminated in the environment. And it is formed in a predetermined width and length to cover the face of the wearer.

Further, the body portion 1100 penetrates one surface, and a through hole 1110 is formed corresponding to the nose and mouth of the wearer.

That is, the through hole 1110 is formed through one surface of the body 1100 so that the air of exhalation is quickly discharged to the outside while blocking the inflow of external fine dust during inhalation and exhalation.

7 and 8, the ventilation part 1200 is formed corresponding to the position of the through hole 1110, and serves to open and close the body part 1100 according to inhalation and exhalation.

To this end, the ventilation unit 1200 includes a ventilation frame 1210, a body filter 1220, a fastening groove 1230, and a fastening protrusion 1240.

The ventilation frame 1210 is formed in a frame shape along the rim of the through hole 1110, and is formed into a rectangular frame after finishing the inner and outer rims of the through hole 1110. This prevents the through hole 1110 from being torn or damaged.

In addition, the ventilation frame 1210 may have a surface formed of silicone or a soft material so as to increase adhesion to the cover frame 1221 to be described later.

The main body filter 1220 is integrally connected to be folded to the upper portion of the ventilation frame 1210 to form a cover frame 1221 for sealing the through hole 1110.

That is, the main body filter 1220 is integrally connected to the outside of the cover frame 1221 and folded to and connected to the ventilation frame 1210 to open and close the through hole 1110.

In other words, the main filter 1220 is made of a non-woven fabric or a synthetic fiber filter and has a size corresponding to the outside of the cover frame 1221. In addition, the body filter 1220 attached to the cover frame 1221 serves as a gate for closing or opening the through hole 1110 according to the wearer's inhalation and exhalation, as shown in FIG. 11.

That is, when the wearer inhales, it is in close contact with one surface of the ventilation frame 1210, and when exhaling, the through hole 1110 is opened by rotating the upper portion of the ventilation frame 1210 around the axis. At this time, air remaining inside the body 1100 is discharged to the outside through the through hole 1110.

The fastening groove 1230 is formed to be concave along the edge of the ventilation frame 1210.

That is, the fastening groove 1230 is formed as a concave groove along the edge surface of the ventilation frame 1210 to which the cover frame 1221 contacts, as shown in FIG. 8.

The fastening protrusion 1240 is formed to protrude from the cover frame 1221 corresponding to the fastening groove 1230. In addition, during the manufacturing process, the shape of the irregularities may be reversed.

In this way, the ventilation unit 1200 opens and closes the through hole 1110 to smoothly discharge the exhaled air, and when inhaling, serves to introduce the purified air into the interior of the body unit 1100.

For example, when the wearer exhales and then inhales, the ventilation unit 1200 is formed by the suction force of air and the magnetic force between the first magnet unit and the second magnet unit. The through hole 1110 opened by rotation is closed.

At this time, the fastening protrusion 1240 formed on the surface of the cover frame 1221 is inserted into the fastening groove 1230 formed in the ventilation frame 1210 to block external air from flowing into the interior of the body part 100. As a result, inflow of external fine particles and dust is blocked, and air is purified through the body portion 1100 made of a filter to flow into the body portion 1100.

On the other hand, the ventilation unit 1200 of the mask 1010 on which the open filter is formed according to an embodiment of the present invention further includes a magnet unit 1250 and a respiration measurement unit 1260 as shown in FIGS. 9 and 10. Can include.

The magnet part 1250 corresponds to the positions of the first magnet part 1251 and the first magnet part 1251 attached to at least one side of the ventilation frame 1210, and is formed on one side of the cover frame 1221. It is formed including two magnets (1252).

The first magnet part 1251 is exposed on one side of the ventilation frame 1210 to which the cover frame 1221 contacts or is formed in the ventilation frame 1210. In particular, since the main filter 1220 is spaced apart from the ventilation frame 1210 to open and close the through hole 1110, it is preferable to be located under the ventilation frame 1210.

The second magnet part 1252 is formed under the cover frame 1221 and contacts each other with the first magnet part 1251 by magnetic force to increase sealing force.

As such, in the magnet unit 1250, either of the first magnet unit 1251 or the second magnet unit 1252 is formed of a permanent magnet or an electromagnet, and the other is formed of a metal member, or both are formed of a permanent magnet. It is also possible to form so that they come into contact with each other.

In addition, when a part of the magnet part 1250 is composed of an electromagnet, the polarity of the magnets is changed to push or pull each other so that the main filter 1220 rotates around the top of the cover frame 1221 as an axis.

Referring to FIG. 10, the respiration measurement unit 1260 measures the wearer's breath by sensing a distance between the ventilation frame 1210 and the body filter 1220. To this end, the respiration measurement unit 1260 includes an electrode 1261, a metal plate 1262, a CPU 1263, and a communication unit 1264, and the communication unit 1264 may be connected to the server 1265.

The electrode 1261 is formed on one side of the ventilation frame 1210. Then, it is connected to the CPU 1263 described later.

The metal plate 1262 serves to represent a change in electrical resistance or a capacitor in response to inhalation and exhalation. That is, the metal plate 1262 is attached to the lower end of the cover frame 1221 and overlaps the electrode 1261 to change the distance between the electrodes 1261 in response to inhalation and exhalation, thereby changing the electrical resistance or capacitor between them. Detect through. And it is regarded as breathing and data processing is performed.

The CPU 1263 receives the electrical signal from the electrode 1261 and measures the respiration rate.

That is, the CPU 1263 repeats that the main body filter 1220 is separated from the ventilation frame 1210 and contacts again by inhalation and exhalation. At this time, the electric resistance between the electrode 1261 and the metal plate 1262 is sensed through a change in a capacitor. And it is regarded as breathing and data processing is performed.

The communication unit 1264 serves to transmit the data measured by the CPU 1263 to the smart terminal S.

The server 1265 serves to convert the respiratory data received from the communication unit 1264 into big data and provide individual medical information to the smart terminal (S).

Here, the server 1265 serves to store data on respiration, store and analyze data for individual and regional management, and provide analysis results to clients.

Although not shown in the drawings of this specification, the respiration measurement unit 1260 is driven by being provided with a battery on one of the surfaces of the body unit 1100. It is preferable that such a battery is selectively made of a rechargeable type and an exchange type.

Meanwhile, the respiration measurement unit 1260 of the mask 1010 on which the open filter is formed according to an embodiment of the present invention may further include a light-receiving unit 1266.

The light-receiving unit 1266 represents a change in light in response to inhalation and exhalation, and serves to convert an optical signal into an electrical signal and transmit it to the CPU 1263.

This is to detect changes in inhalation and exhalation with light, instead of detecting changes in inhalation and exhalation by electrical signals in the electrode 1261 and the metal plate 1262.

Referring to FIG. 7, the frame portion 1300 is formed in a rectangular frame corresponding to the shape of the ventilation portion 1200 and is detached from the inner surface of the ventilation portion 1200.

In particular, the frame unit 1300 prevents the shape of the ventilation unit 1200 from being deformed by breathing on one side of the body unit 1100, and serves to secure a breathing space together with the support unit 1400 to be described later.

Further, the frame unit 1300 is illustrated in a wire shape, but may be manufactured in a soft shape having a flat surface, or may be mechanically fused to the ventilation unit 1200 to be manufactured.

Referring to FIGS. 8 and 9, the support unit 1400 extends to the upper and lower portions of the frame unit 1300 to secure a breathing space for the wearer.

To this end, the support part 1400 includes an extension part 1410 and a clip part 1420.

The extension portions 1410 are extended to both sides of the frame portion 1300, and are formed in a pair along the inner surface of the body portion 1100.

In addition, the extension portion 1410 may be manufactured not only in a wire shape, but also in a soft shape having a flat surface. And it is also possible to be manufactured in a state coupled to the nose clip formed on the nose of the mask.

The extension part 1410 extends from the frame part 1300 and can be bent in response to the shape of the wearer's face, thereby securing a breathing space.

The clip portion 1420 crosses from one end of the extension portion 1410 and may be deformed to correspond to the shape of the nose and the chin.

In particular, the clip unit 1420 serves to improve the inconvenience caused by wearing a mask of a wearer of glasses.

In addition, the clip portion 1420 crosses the extension portion 1410 to form a horizontal direction, thereby preventing the body portion 1100 from being wrinkled.

Due to this, the wearer can comfortably wear the mask.

In addition, the extension portions 1410 of the mask 1010 on which the open filter according to the embodiment of the present invention is formed are extended to both sides of the frame portion 1300 in one direction as shown in FIG. 12, and the upper portion of the frame portion 1300 And at least two or more extending from one of the lower portions.

For example, when the extension portion 1410 formed on the nose portion is formed as a head line, it prevents the formation of marks on the nose, thereby preventing the wearer from discomfort or pain caused by pressing the nose.

Next, when the extension portion 1410 formed in the chin portion is formed in two lines, the load of the body portion 1100 is supported to support the frame portion 1300 being struck downward.
