In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, preferred embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously implemented by those skilled in the art without being limited thereto.

1 illustrates a configuration diagram of a mask provided with a flap and a flap protection unit and a respiration measurement unit according to an embodiment of the present invention.

One embodiment includes a flap 130 of the mask, and a respiration measurement unit 160, and may further include a flap protection unit 170 for protecting the flap 130.

In detail, the mask 100 according to an embodiment is mounted on the user's face and opened and closed by the body portion 110 having a through hole formed therein, the frame portion 120 installed along the periphery of the through hole, and the frame portion 120 . It includes a flap 130 that is installed to be possible.

And in one embodiment, the flap opening limiting part 150 for limiting the degree of opening of the flap 130, the flap protection part 170 positioned in front of the flap 130 and fastened to the frame part 120, the body part It is located on the rear surface of 110 and may further include protrusion-shaped sensor parts 161 , 162 , 163 and a support part 190 .

And the respiration measurement unit 160 of one embodiment, the body portion 110 and the frame portion 120 by using the support portion 190 penetrates a portion of the flap 130 while attached to be detachably attached to the frame portion 120. Respiration can be measured according to the reciprocating motion of

The body 110 may be formed of a filter material, for example, a non-woven material, to surround the wearer's face and block the inflow of external air pollutants such as fine dust and yellow sand, and is made of cloth in a mask for cold protection or sports can be In addition, the body portion 110 has a through hole through which the wearer can breathe in and is located in the front central portion.

The frame part 120 is disposed around the through hole formed in the body part 110 .

Respiratory measurement unit 160 is mechanically through the body portion 110 by using the protrusion-shaped support portion 190 is fastened with the frame portion (120). The support part 190 is made of a flexible and elastic material so that its properties do not change even after repeated detachment and detachment several times, and it does not easily detach while being easily attached and detached.

The flap opening limiting part 150 includes a rotation shaft 151 connected to the frame part 120 and a first member 153 and a second member 155 and a second member 155 extending from the rotation shaft 151 . It may include a weight body 157 installed at one end of the , a detailed description thereof will be described later.

2 illustrates a front view of a frame unit and a sensor unit disposed in a through hole according to an embodiment of the present invention.

The flap 130 is configured to open and close the through hole through which the gas passes through the body portion 110 according to the wearer's exhalation and inhalation, and the shape thereof is formed to correspond to the through hole, and upon inhalation, the body The through hole is closed together with the part 110 . The flap 130 also performs a filter function and may be formed of a filter material, for example, a non-woven material, and may be made of cloth in a mask for cold protection or sports use.

Here, the flap 130 is differently affected by gravity according to the posture of the wearer's face, and as a result, the force required to close the flap 130 again after opening is changed. Such a closing force is dependent on the wearer's suction force due to inhalation, the elastic force of the flap 130, and magnetic force when one or more pairs of magnets are provided between the frame part 120 and the flap 130, and the suction force is different for each wearer. may occur.

In particular, in the case of children, women, and the elderly having a relatively small suction force, the closing force becomes relatively small, and thus a means for completely closing the flap 130 during inhalation is required. In particular, a means to offset the effect of gravity of the flap may be required, and for this purpose, the flap opening limiting unit 150 may be included.

The flap opening limiting unit 150 includes a rotating shaft 151 and a weight body ( 157), the first member 153 and the second member 155 extending in different directions about the rotation shaft 151 based on the principle of the lever are configured to operate in conjunction. It is also possible to increase the weight of the second member 155 according to circumstances so as to perform the role of the weight body 157 together.

The flap opening limiting unit 150 provides a means for the flap to overcome gravity and to be stably closed even with weak breathing even when the wearer's head is facing down. This is exemplified in detail in FIG. 5 .

The upper edge of the flap 130 is attached to the upper frame part 123 so that the flap 130 is opened and closed while rotating around the edge.

Here, the frame part 120 may be formed of a rigid material having a predetermined thickness. In this case, it is possible to maintain the shape around the through hole of the body part 110 to which the frame part 120 is attached, and also to be opened and closed. By maintaining a uniform contact surface with the flap 130, the degree of adhesion during opening and closing of the flap 130 is constant.

The frame portion 120 may be formed in various shapes to correspond to the shape of the through hole formed in the body portion 110. In an embodiment of the present invention, the four frame members 121 located on the lower side, the upper side, the left side, and the right side , 123, 125, 127) may be configured as a rectangular frame in which the ends are respectively coupled.

As illustrated in this figure, the respiration measurement unit 160 is mechanically located on the back surface of the body unit 110 and is configured to be detachably attached to the body unit 110 and the frame unit 120 . Respiratory measurement unit 160 largely includes sensor units (161, 162, 163) capable of sensing the timing of inhalation and exhalation and the amount of respiration, and a circuit unit for receiving this signal, interpreting the contents, and processing it into useful information for the wearer.

In addition, the respiration measurement unit 160 has a built-in precision sensor unit, an electric circuit and a battery, and can be used semi-permanently.

However, the body part 110 and the flap 130 are disposable when made of non-woven fabric, and can be washed when used as a cloth. Therefore, the respiration measurement unit 160 is configured to be detachably from the body portion 110 and the frame portion 120, thereby promoting convenience and economy of use.

The sensor units 161 , 162 , and 163 illustrated in this figure may detect signals from the movement of the flap 130 and the weight 157 .

Exemplary sensor units (161, 162, 163) may include a metal plate (161a) and a reflecting plate (163a) attached to the flap 130 that is mechanically installed in the respiration measurement unit 160, the second member extension 158) Alternatively, the weight body 157 may be included. A detailed description thereof will be described later in the following drawings.

3 illustrates a detailed cross-sectional view of a frame unit and a sensor unit according to an embodiment of the present invention.

In order to describe one embodiment in more detail, this figure illustrates a cross-sectional view of three sensor units 161 , 162 , and 163 .

As here, the sensor unit (161, 162, 163) may include the electrodes (161b, 162b) and the light transmitting and receiving unit (163b) that are mechanically installed in the respiration measurement unit (160). Embodiments of the sensor units 161 , 162 , and 163 may include a metal plate 161a and a reflective plate 163a attached to the flap 130 , and the second member extension 158 and a metal plate installed on the weight 157 ( 162a) can be used to measure respiration.

In one embodiment, the electrodes 161b and 162b and the light transmitting/receiving unit 163b are mechanically configured in a protrusion shape, penetrate the body unit 110 like the support unit 190 and are fastened to the frame unit 120, and a flap ( 130), the respiration state of the wearer is detected while approaching or contacting the metal plate 161a or the reflecting plate 163a or the extension 158 of the second member 155 or the weight 157 installed at the lower end of the 130).

The three sensor units 161 , 162 , and 163 of the above example can be configured as three or less sensors depending on the situation, and mechanically, they are combined into one protrusion shape and mounted, so that economy and ease of attachment and detachment can be realized together.

The first sensor unit 161 passes through the body unit 110 and the frame unit 120 in the respiration measurement unit 160 to make contact with the metal plate 161a located at the lower end of the flap 130 and the electrode 161b and can work together.

The second sensor unit 162 includes an electrode 162b penetrating through the body 110 and the frame 120 to contact the weight 157 or the extension 158 of the second member 155 and can act as a combination of

The third sensor unit 163 may include an optical transceiver 163b in combination with a reflecting plate 163a positioned at the lower end of the flap 130 through the body portion 110 and the frame portion 120 .

Here, in the first sensor unit 161, the metal plate 161a of the flap 130 repeats contact or non-contact with the corresponding electrode 161b even in weak respiration to detect the timing of inhalation and exhalation.

On the other hand, when the respiration pressure is above a certain level, in the second sensor unit 162, the weight 157 or the extension 158 of the second member 155 repeatedly contacts or non-contacts the corresponding electrode 162b and inhales. And it is possible to measure the respiration rate of the exhalation. That is, in weak respiration, the radius of motion of the flap 130 is small enough to repeat contact or non-contact only with the electrode 162b of the first sensor unit 161, so that the electrode ( 162b) is not reached.

However, when the second sensor unit 162 repeats contact and non-contact, the amount of respiration is to a certain extent large, so that the flap 130 moves through the first member 153 to the weight body 157 or the second member 155 . This is a case in which the extension 158 can be pushed toward the body 110 . When the respiration becomes larger and the flap 130 moves larger, the situation may be detected by the third sensor unit 163 .

That is, the third sensor unit 163 moves the reflecting plate 163a located at the lower end of the flap 130 in a circular motion around the frame upper part when the flap 130 moves large, so that the light transmitted from the optical transceiver 163b is reflected by the reflecting plate. There is no return at (163a), and this can be used to measure a large amount of respiration per time unit of the wearer. This will be described in detail with reference to the following drawings.

4 illustrates the circuit portion of the respiration measurement unit 160 according to an embodiment of the present invention.

Referring to this figure, the electrodes 161b and 162b of the sensor units 161, 162 and 163 or the optical transmitter and receiver 163b are the sensor interface unit 165 of the circuit unit and the central processing unit (CPU) unit 166 and the wireless connection unit. (167) can be connected.

The circuit unit may include a battery 168 for supplying power. The wireless connection unit 167 delivers the data finally detected by the CPU unit 166 to an intelligent device such as a smart phone (SP) to drive various application programs, which are again connected to the central server (S) so that more wearers The data obtained from it is widely available.

As exemplified here, the signals detected by the sensor units 161, 162, and 163 are generated by the CPU unit 166 through the sensor interface unit 165 located inside the circuit unit to determine the wearer's breathing condition.

This data may be connected to an intelligent device such as a smart phone (SP) or a personal computer through a wireless connection unit 167 such as Bluetooth or Wi-Fi. Afterwards, the wearer's breathing information is connected to a bio-signal measuring device attached to the body, such as a smart watch, pulser, or oxygen saturation meter to analyze the wearer's breathing pattern during normal or exercise and comprehensively judge it with other bio-information in an emergency situation. It is also possible to judge and provide medical information such as desirable breathing methods for health promotion. When such information is concentrated and collected on the server (S) from several people, in addition to the services related to individual health as described above, it is possible to provide a means to effectively cope with situations such as epidemics by grasping the local community or national breathing situation. can

5 illustrates a state diagram at the time of inspiration of a flap and a flap opening restriction according to an embodiment of the present invention.

Referring to this figure, if the user's head faces downward as an example, the flap opening limiting part 150 is the first member ( The force that pushes the flap 130 in the direction of the frame part 120 is applied by the 153). This allows the flap 130 to be easily closed when breathing in.

In addition, when the wearer switches to exhalation in such a situation, the flap 130 is opened by the exhalation pressure, and the flap 130 pushes the first member 153 in all directions, and thus the weight body 157 moves to the first member ( 153) is approached toward the body portion 110 in the opposite direction. That is, when the wearer breathes with a normal intensity, the weight 157 reciprocates as indicated by an arrow in FIG. 5 as a direction closer to or away from the body 110 . That is, the reciprocating motion of the weight body 157 and the flap 130 is constant except for the case where the head is directed upward and the weight body 157 comes into contact with the body unit 110 even when exhaling, thereby preventing the reciprocation movement. In a normal situation above respiration pressure, it always occurs according to the imbalance of force between the flap 130 and the weight 157 according to the inhalation and exhalation. have.

6 illustrates a sensor unit according to an embodiment of the present invention.

Referring to this drawing, the first and second sensor units 161a, 161b, 162a, and 162b may be configured by one of three means of (a), (b), and (c) of FIG. 6 .

In (a) of FIG. 6 , the first sensor units 161a and 161b are exemplified by using a phenomenon in which the resistance or capacitance between the electrodes changes when the flap 130 is opened or closed by a combination of an electrode and a metal plate. timing and respiration volume.

That is, when the flap 130 is closed by inhalation, the resistance decreases and the capacitance increases, and when the flap 130 is opened by the exhalation, the resistance increases and the capacitance decreases.

In (b) of this figure, when the flap 130 is opened or closed by a combination of an inductor and a metal plate or other magnetic material, the inductance of the inductor changes using a phenomenon to detect the timing and respiration amount of inhalation and exhalation.

In (c) of this figure, the timing and respiration amount of inhalation and exhalation are detected by using a blocking plate 161a for blocking light between the light transmitting and receiving units 161b. This sensing method can be used in accordance with the use situation, such as the strength of electromagnetic waves or moisture resistance in accordance with the design of the entire respiration measurement unit 160, respectively. That is, although the above description uses the first sensor units 161a and 161b as an example, one of the above methods may be used for the second sensor units 162a and 162b as well.

Referring to (d) of this figure, the light transmitting/receiving unit 163b faces the reflecting plate 163a located at the lower end of the flap 130, and the flap 130 largely moves in a circle around the upper frame of the frame, and the light transmitting unit 163b ), when the light emitted from the reflector 163a does not return, the signal can be detected, so that it is possible to check a situation in which the wearer breathes a lot.

By using the first, second, and third sensor units 161, 162, and 163 in this way, it is possible to measure the timing of inhalation and exhalation and the amount of respiration of the wearer.

The flap protection unit 170 is attached to the outside of the frame 120 to protect the flap 130 and the flap opening limiting unit (not shown in FIG. 7 ).

Referring to (a) of this figure, the electrodes 262b and 263b of the second sensor units 262a and 262b and the third sensor units 263a and 263b are positioned inside the flap protection unit 170 and the flap 130 ) while rotating, the flap 130 on the electrodes 262b and 263b of the second sensor units 262a and 262b and the third sensor units 263a and 263b installed inside the flap protection unit 170 according to the size of the movement. ), a change in resistance, capacitance, inductance, or light that occurs as the metal plate or magnetic material or blocking plate 262a, 263a approaches or comes into contact with each other can be read.

The mechanically flexible flap 130 may be overlapped with the electrodes 262b and 263b while rotating, but is flexibly bent and passes through each electrode. Signals detected from the electrodes 262b and 263b are transmitted to the sensor interface (not shown in FIG. 7 ) of the circuit unit through the connector 264 .

In this embodiment, the second sensor unit 262a, 262b and the third sensor unit 263a, 263b are preferably installed in a position where the flap 130 is most flexible, and the center of the lower end of the flap 130 and corresponding The inner center of the flap protection unit 170 may be used.

At this time, in order to connect the measured signal to the circuit unit, a signal line may pass through the inside of the flap protection unit 170 and be connected to the connector 464 .

In the embodiments of the present invention, a method for measuring the timing and respiration volume of inhalation and exhalation using three sensors has been described, but the number of sensors may be different. For example, a mask specialized for sports may have a very large breathing volume, and the height of the flap protection unit 170 may be made higher so that the flap 130 can sufficiently exercise. In this case, it is possible to more accurately subdivide and measure the respiration volume with three or more sensors. Conversely, if weak or normal breathing is assumed, the object pursued by the present invention may be achieved while reducing the cost by reducing the number of sensors.

(not shown) may be installed to control the closing force or opening force of the flap 130 in connection with the data obtained from the respiration measurement unit 160 . For example, in the case of a person with weak breathing, when it is difficult to completely close the flap 130 with only the pressure of inhalation, by applying power to the first magnet (not shown) through the control of the separate CPU unit 166, the second magnet ( (not shown) may help to close the flap 130 by strengthening the attractive force. Such a magnet part may be used in conjunction with the flap opening limiting part 150 as in FIG. 1 or may be used in the mask 200 using the flap opening limiting part 250 without a weight as in FIG. 8 to be described below. .

8 illustrates a front view of a flap opening restriction according to an embodiment of the present invention.

Referring to this figure, in the mask 200 provided with the flap 130 according to the present embodiment, the upper edge of the flap 130 is located on the upper frame part 120 of the body part 110 so that the through hole can be opened and closed. is coupled, and extends in the horizontal direction on the outer surface of the flap 130 to limit the degree of opening of the flap 130 and includes a flap opening limiting portion 250 that is installed spaced apart.

In the case of using the flap opening limiting part 250 , the mask can be configured without the weight body 157 .

Therefore, a separate gyro sensor (not shown) is mounted on the circuit unit to detect information according to the wearer's head position as an electrical signal, and then the signal sent from the CPU unit to the first magnet (not shown) can be controlled using this. . That is, when the gyro sensor (not shown) determines that the wearer's head is facing downward, the signal sent from the CPU unit to the first magnet (not shown) is strengthened to prevent the flap 130 from sagging downward due to gravity, making it more stable to be able to close the flap 130 . That is, the magnet unit (not shown) can be used together with the flap opening limiting units 150 and 250 to help close the flap 130, and its magnetic force can be adjusted according to the control of the CPU unit, and a separate gyro sensor (not shown) In case of using the head position information, it can be utilized in the CPU part and the control accuracy can be increased.

According to this, the adhesive part 300 is installed in some parts such as the bridge of the nose or the part around the chin where external air easily leaks in an annular shape or as a part of the annular shape on the peripheral part of the rear surface of the body part 110 .

The adhesive part 300 is positioned around the body part 100 as illustrated, and may prevent the inflow of external air from a gap around the body part 100 .

In the adhesive part 300 , the body adhesive layer 310 is directly and permanently attached to the body part 110 , and the skin adhesive layer 320 is temporarily attached to the skin. The intermediate layer 330 is located between the body adhesive layer 310 and the skin adhesive layer 320 and may be composed of a synthetic resin having the property of a soft cushion to give a good feeling to the skin. A protective sheet 340 is disposed on the outside of the skin adhesive layer 220 and may be removed before the wearer wears the mask.

The protective sheet 340 is also made of a material that is easy to contact with the skin, so that if the wearer does not want it, it can be used without removing the protective sheet 340 . That is, the wearer's choice can be broadened depending on the situation in which the wearer does not like the adhesion of the skin adhesive layer 320 to the skin or the external air may leak to some extent through the gap between the mask and the skin contact area according to the external fine dust environment. have. In a conventional mask without a large penetration hole, the gap between the mask and the skin contact area is useless as a passage for external air to leak during breathing in. is also responsible

Therefore, in the existing mask, if the gap is blocked without securing a separate exhaust space during exhalation, it will inevitably result in the elimination of the exhaust passage, which is a net action of the gap, and thus air discharged from the body inside the mask By being piled up, it is difficult to employ the adhesive part 300 as in the present invention.

However, in the mask according to the present invention, a large through-hole and flap 130 that can smoothly discharge air during exhalation are provided to facilitate exhalation of exhalation. Unlike other masks, the mask is not greatly needed, and on the contrary, only a negative role is left as an inflow path of unfiltered air during inhalation, which is an adverse action of the gap.

Therefore, the present invention can solve this problem by installing the adhesive part 300 on the periphery of the back of the mask. It can also be used partially. Another additional advantage according to the adoption of the adhesive part 300 is that the mask can be prevented from flowing down.

Although a method such as strengthening the strength of a strong nose bridge support wire or a rubber band connected to the head or ears is used to prevent dripping in a conventional mask, the adhesive part 300 according to an embodiment of the present invention is replaced on the back side. It can be used wholly or partially in its shape to prevent the mask from flowing down, so it can strengthen the comfort of wearing by lowering the strength of the nose bridge support wire or connecting rubber band. We can provide a variety of products.

In addition, a large amount of moisture is discharged during exhalation through the through hole of this mask. In particular, when the external temperature is low, such as in winter, in order to effectively treat the moisture condensing on the through hole on the back surface of the body part 110 and its periphery, water repellent treatment is performed on the back side of the mask, or a nonwoven fabric made of a material that has been previously water repelled. You can use cloth.

The water-repellent treated back surface 180 may condense the condensed moisture on the surface without penetrating the inside of the mask, so that when the wearer is shaken due to movement or walking, it can be collected at the lower end of the mask back surface 180 . Since the existing mask does not have a through hole, exhalation affects the entire back surface of the mask, and accordingly, the condensed moisture is also spread over the entire back surface of the mask. Therefore, in order to reduce the direct contact of moisture with the skin, some masks for fine dust are coated with a hydrophilic coating to collect the moisture that has condensed inside the back of the mask. However, the collected moisture caused the side effect of lowering the filter efficiency.

In the present invention, unlike the conventional mask, exhalation is mainly discharged through the through hole, and thus the condensed moisture is also increased around the through hole. It is possible to reduce the phenomenon of moisture being captured inside a large area of the back surface, and the wearer is more comfortable and can wear it with high fine dust collection efficiency. This structure can also be applied to a mask made of cloth. In addition, it is possible to make the inside of the mask comfortable by installing the absorbent member 290 having a good ability to trap moisture at the lower end as described above.

Here, the installation position of the absorption member 290 is preferably installed in a place where moisture condensed in the inner surface of the body portion 110 can be collected. In the embodiment of FIG. 10 , it is possible to effectively remove moisture generated by inhalation/exhalation through the nose or mouth by installing it on the bending line located below the through hole.

11 illustrates a structural diagram of the respiration measurement unit and the extension according to an embodiment of the present invention.

As another embodiment of the present invention, when the body part 110 is difficult to bear the weight of the respiration measurement unit 160, the upper and lower extension parts 195 as shown in this figure are placed and the weight is distributed to the nose bridge and chin of the wearer. can do it The extension portion 195 is connected to the upper and lower portions of the respiration measurement unit 160 and extends in the direction of the bridge of the nose and the chin, and is connected to the clip portion 196 . The clip part 196 extends crosswise from one end of the extension part 195, is deformed to fit the shape of the bridge of the nose, and can be comfortably worn on the chin.

As another embodiment of the present invention, a sensor (not shown) such as VOC, CO2, fine dust, and bad breath is attached to the inside of the body unit 110 to obtain information on the quality of the air that is breathed from the CPU unit to obtain information on the smart phone Health information can be delivered to the user by transmitting it to the back or in conjunction with a device that can obtain pulse information, such as a smart watch (not shown). The attachment position of the sensor (not shown) can also be installed in the mechanism part or the extension part 195 of the respiration measurement unit 160 . In this case, the signal from the sensor (not shown) can be used by detecting the signal in the CPU unit 166 by including a signal line inside the extension 195 and connecting it to the circuit unit of the respiration measurement unit 160 .

In addition, solid oxygen (not shown) or fragrance (not shown) used for fragrance therapy can be put in a small package to the mechanism or extension part 195 of the respiration measurement unit 160 to be detachably attached to them.

In addition, as another embodiment of the present invention, the time and place the wearer spent in the fine dust in conjunction with the accumulated data of the amount of respiration measured by the mask and the app that shows the fine dust situation on a smartphone, etc. can be comprehensively evaluated to inform the wearer when the remaining consumable parts can be replaced except for the semi-permanently used circuit measurement unit 160 . In addition, if the wireless connection unit 167 is always linked to a smartphone with a technology such as Bluetooth and linked with the fine dust app, it is possible to prevent in advance the situation of going out with only a smartphone with a mask on a day when there is a lot of fine dust.

12 illustrates various structural diagrams of a frame and a flap according to an embodiment of the present invention.

As another embodiment of the present invention, the structure of the frame part 220 and the flap 230 of various through-holes is shown.

(a) of this figure is a sub-frame of a certain shape within the frame 220, and a horizontal sub-frame 221, a vertical sub-frame 222, a cross-sub-frame 223 combined with horizontal and vertical, and a constant within the frame 220 A sub-frame 224 of the shape is shown.

The flap 230 is installed on the frame 220 in accordance with the frame 220 and the sub-frames 221 , 222 , 223 , 224 .

In (b) of this figure, a front view and a side view of the flap 330 and the small sub-flap 331 operating on the flap 330 are shown. The sub-flap 331 is disposed on the flap 330 to provide an additional opening when exhaling, thereby making breathing more convenient during intense breathing activities such as sports. Even in the structures of various frames and flaps shown in the examples of this figure, the flap opening limiting portions described in the above embodiments may be installed by changing them according to their respective shapes.

13 illustrates a configuration diagram of a mask provided with a flap and a flap protection unit according to an embodiment of the present invention.

This figure discloses an example in which the user wears the mask according to the embodiment.

The mask 100 according to the disclosed embodiment is mounted on the user's face and can be opened and closed by the body portion 110 having a through hole formed therein, the frame portion 120 installed along the periphery of the through hole, and the frame portion 120 . It includes a flap 130 to be installed.

The mask 100 according to the embodiment may further include a flap opening limiting part 150 for supporting the movement of the flap 130 according to the user's breathing and a flap protecting part 170 protecting the flap 130 .

The flap opening limiting part 150 to be disclosed is a weight installed at one end of the rotation shaft 151 and the first member 153 and the second member 155 and the second member 155 extending from the rotation shaft 151 . It may include a sieve 157, which will be described later in detail.

The embodiment disclosed herein is similar to the embodiment illustrated in FIG. 1, but on the first member 153, one or more disks 152 or a shape 152 having a structure that surrounds all or part of the first member 153 is formed. may include

When the first member 153 includes one or more disks 152 or a member 152 having a structure surrounding all or part of the first member 153, the flap opening limiting unit 150 is the mask 100 when the user breathes. It can be opened and closed smoothly according to the

For example, the first member 153 may be positioned on the flap 130 to support the flap 130 when the user's face faces downward.

As described above, the flap opening limiting unit 150 may be configured by connecting the rotation shaft 151 and the first member 153 and the second member 155 extending from the rotation shaft 151 . The first member 153 and the second member are configured to include a weight body 157 installed at one end of the second member 155, and extend in different directions about the rotation shaft 151 by the principle of a lever. (155) can be interlocked to operate.

Of these, the first member 153 pushes up the flap 130 while the weight body 157 faces downward when the user's head faces downward, and closes the flap 130 during inhalation. can help

In addition, the first member 153 may be in contact with the flap 130 when the flap 130 is opened during exhalation, and the degree of opening of the flap 130 may be determined. That is, the first member 153 may be in contact with the flap 130 and serve to control the closing and opening of the flap 130 .

However, the flap 130 and the peripheral portion may condense moisture in the body discharged during exhalation. In such a case, the free movement of the flap 130 may be hindered due to the viscous resistance of moisture when in contact between the flap 130 and the periphery of the flap 130 .

In the embodiment according to the present invention, a thin disc 152 is installed on the first member 153 so that the disc 152 or a structure 152 of another shape is formed between the flap 130 and the first member 153 . to act as a point of contact.

The first member 153 includes one or more disk-shaped members 152 surrounding the first member 153 , and the disk-shaped member 152 includes the flap 130 and the first member 153 . The contact area can be minimized.

In this way, the disk 152 can be made extremely small by minimizing the contact area between the flap and the first member 153 . Through this, the movement of the flap 130 can be made freely by minimizing the viscous resistance of the moisture condensed between them.

As a result, one or more disks 152 provide a means for smoothly operating the flap 130 of the mask 100 in which the flap opening limiting part 150 is installed.

In this figure, the disc 152 discloses an example in which two left and right are installed, but one or more may be installed to minimize the overall contact area between the flap 130 and the first member 153 and to smoothly open and close the flap 130. can Alternatively, a structure having a shape other than the disk 152 is also possible.

14 is a view each illustrating a front view (a) and a side view (b) of the mask according to the embodiment.

Referring to the front view (a), the mask 100 according to the embodiment has a body portion 110, a frame portion 120, a flap 130 installed on the frame portion 120, and a flap opening restriction as described above. part 150 may be included.

The mask 100 according to the embodiment may further include a flap opening limiting unit 150 for controlling the movement of the flap 130 according to the user's breathing and a flap protecting unit 170 protecting the flap 130 .

The flap opening limiting unit 150 is connected to the rotation shaft 151 and the first member 153 and the second member 155 , and a very small structure 152 is installed on the first member 153 . Here, the structure 152 may have a shape such as a disk.

As illustrated in the front view (a), the flap 130 is bent in the horizontal direction in a state attached to the upper side of the frame unit 120 and repeats opening and closing. In order to work well even with weak breathing, the flap attachment part 131 located on the upper side of the flap 130 must be extremely flexible. The flap 130 may be formed of several layers, and may generally have three layers.

Referring to the side view (b), the flap 130 may include the frame part 120 and the flap attachment part 131 attached to it, and a plurality of filters. Here, an example in which a plurality of filters is composed of three filters 133 , 134 , and 135 is disclosed.

The filters of the embodiment include a meltblown filter (MB) filter 133 for filtering fine dust. And, the inner and outer sides of the flap 130 include separate spunbond (SB) filters 134 and 135 to protect the skin and the MB filter 133 and assist the filter function. In addition, a structure (not shown) surrounding the frame 120 with a thin vinyl film (not shown) to strengthen the adhesion with the frame 120 on the inside of the skin-side spunbond (SB) filter 134 may be additionally selected. may be In the embodiment, if one layer of the user's skin-side SB filter 134 is used as the flap attachment part 131 , it can help the flexibility of the material of the flap 130 . For example, to add flexibility to these materials, the directionality given when SB filters are produced can be used. This will be described later.

15 is a diagram illustrating the relationship between the spunbond (SB) filter and the flap described above.

At least one of the vertical fusion part 136 and the horizontal fusion part 139 may be generated on the flap 130 . At this time, the direction of the vertical fusion part 136 or the horizontal fusion part 139 may be as shown in this figure and the following description to make the movement of the flap 130 flexible.

The spunbond (SB) filter has a flexible characteristic toward the direction in which the roll 236 of the filter rotates (arrow 137 direction) from the time of production. Accordingly, when the horizontal fusion portion 139 is aligned with the rotational direction of the roll 236 (arrow 137 direction), the flap including the spunbond (SB) filter may also have a flexible characteristic in the horizontal direction.

That is, when producing a melt blown (MB) filter and a spunbond (SB) filter, the mask flap is formed so that the direction of the filter roll 236 (arrow 137 direction) is aligned with the horizontal direction (arrow 138 direction) of the flap 130 . can do. In this way, if the horizontal direction (arrow 138 direction) of the flap coincides with the direction (arrow 137 direction) of the roll 236 during filter production, the flap 130 is flexible in the horizontal direction so that it can be bent well. It can be well open and closed.

In addition, if only one side of the user's skin side spunbond (SB) filter 134 is used as the flap attachment part 131, there is an effect that can further maximize the flexibility of the flap 130.

That is, the flap of the mask according to the embodiment may be formed of a spunbond filter and a meltblown filter, and the horizontal direction of the flap (arrow 138 direction) and the rotation direction (arrow) of the spunbond filter when producing the spunbond filter 137), the Roll to Roll direction can be matched.

In addition, the spunbond filter fuses a fine pattern on its surface to maintain its mechanical shape. During the fusion process, there is a surface that is deeply engraved with a fine pattern and a surface that is shallowly engraved. The surface of the skin-side spunbond (SB) filter 134 in contact with the frame portion 120 is selected to have a shallowly engraved surface, thereby increasing the degree of adhesion between the spunbond (SB) filter 134 and the frame portion 120. can be improved

16 is a view showing a detailed exemplary view of the flap of the mask according to the embodiment.

In the example of this figure (a), the flap 130 is a flap attachment part 131, a spunbond (SB) filter 134,135, a horizontal fusion part 139 located on the spunbond filter 134, a vertical fusion part 136 and a peripheral fusion portion 132 . Here, the spunbond (SB) filter 134 may be a filter on the user's skin side, and the spunbond (SB) filter 135 may be a filter outside the mask.

In general, a nonwoven mask is manufactured through ultrasonic fusion, and there is a starting surface in which the protrusion-shaped metal that supplies ultrasonic energy comes into contact with and a final finishing surface finished by passing through filters to be fused. During fusion, the nonwoven fabric melts and reduces its volume, and then mechanical deformation occurs around the fusion site. Such mechanical deformation usually occurs larger than the surface of the welding initiation surface compared to the surface of the welding finishing surface.

A horizontal fusion part 139 may be positioned at one end of the flap attachment part 131 . The horizontal fusion part 139 is arranged with the spunbond filter 134 on the skin side as the fusion start surface. Then, the horizontal fusion part 139 decreases in volume during fusion, and thus the flap 130 is bent in the frame part 120 direction. It can create stress. By using this phenomenon, the horizontal fusion part 139 may enhance the sealing property of the mask 100 by allowing the flap 130 to more easily contact the frame part 120 .

In addition, in (a) of this figure, the peripheral fusion portion 132 is located on the periphery of the flap 130 and serves to bind three other filters 133, 134, and 135 together. The shape is formed in a straight line fused like a fine groove of a filter on the flap 130 . The peripheral fusion part 132 uses a change in the mechanical shape that reduces the volume and bends during fusion so that the skin-side spunbond (SB) filter 134 is in stable contact with the frame part 120 to maximize the sealing degree. As described above, during ultrasonic welding, more mechanical deformation occurs in the direction in which the volume is reduced on the surface where the welding is started than the surface on which the welding is finished passing through it. Therefore, the peripheral fusion portion 132 uses the skin-side spunbond (SB) filter 134 as the starting surface, the fusion penetrates the three filters 133, 134, and 135, and is finished in the outer spunbond (SB) filter 135. In this way, while the three filters 133, 134, and 135 are fused, the shape of the periphery of the flap 130 is bent in the frame part 120 direction, so that the contact area with the frame part 120 is increased, and consequently, the sealing degree of the flap 130 is maximized. can do.

The peripheral fusion portion 132 may be formed in various shapes on the flap 130 . For example, fusion may be performed on one surface of the flap 130 in a straight line, a surface, or a circle, and when the fusion in a circular shape is formed, a disk fusion part may be located on one surface of the flap 130 .

At least one of the horizontal fusion part, the vertical fusion part, the peripheral fusion part, or the disk fusion part may be positioned so that the fusion is formed on one surface of the flap in the form of a straight line or a surface.

As illustrated in (b) of this drawing example, the vertical fusion part 136 inside the flap 130 serves as a hinge when the flap 130 is opened and the flap attachment part 131 is bent horizontally. It serves to make a straight shape as much as possible by preventing the other parts of the flap 130 from being easily bent or rolled in the horizontal direction except for the lower end.

Then, when the flap 130 is exercised according to the user's breathing, the area in contact with the flap protection unit 170 can be minimized. When the contact area between the flap 130 and the flap protection unit 170 is minimized, the contact area between the flap 130 and the moisture condensed on the periphery thereof is minimized. Then, when exercising according to the user's breathing of the flap 130, the flap 130 may be rolled up and not interfere with the movement, such as movement.

As illustrated in this figure (b), when the vertical fusion part 136 is installed with the skin-side spunbond (SB) filter 134 as the fusion start surface, the volume is reduced during fusion, and the flap 130 is the frame part 120. It can create stress that bends in the direction. Accordingly, the flap 130 may more stably contact the frame portion 120 so that the sealing force can be strengthened.

(c) of this figure shows a side view in which the flap protection unit 170 is installed with respect to the flap 130 moving in this way. The vertical fusion part 136 inside the flap 130 serves to prevent it from being easily bent or rolled in the horizontal direction when the flap 130 is opened to make a straight shape as much as possible.

In this figure, the disc 152 may be positioned on the first member 153 connected to the flap opening limiting unit 150 . At one end of the second member 155 , a weight 157 serves to close the flap 130 according to the user's breathing. The disc 152 on the first member 153 prevents contact with the flap protection unit 170 even if viscosity occurs due to condensation moisture when the flap 130 is excessively opened according to the user's breathing. This may serve to prevent the flap 130 from being disturbed.

In (c) of this figure, the contact area between the disc 152 and the flap 130 can be further reduced by separately providing a disc fusion portion (not shown) at a portion where the disc 152 is in contact with the flap 130 . In particular, it is possible to reduce the resistance that can be made in contact with the original plate 152 , such as lint, which may be attached to the surface of the outer spunbond (SB) filter 135 of the flap 130 made of the nonwoven fabric.

For reference, the vertical fusion part 136 is generated vertically in the flap direction for the three filters 133, 134, and 135 described.

On the other hand, in the example of this figure (d) illustrates the operation of the flap 130 when the flap 130 is particularly flexible in the horizontal direction and there is no vertical fusion portion 136 as disclosed above.

When there is no vertical fusion part 136 on the flap 130, the flap 130 is excessively bent during exhalation, and the viscous resistance with condensed moisture increases, so the flap 130 has a large area with the flap protection part 170. can be contacted In this case, the movement of the flap 130 may be restricted due to viscous resistance according to the user's breathing and condensed moisture.

17 is a diagram illustrating a flap locking device for a mask according to an embodiment and an operation thereof.

In the embodiment illustrated in this figure, the frame unit 120 may include a flap locking device 360 capable of closing the flap 130 .

A flap locking device 360 may be included on one side of the frame unit 120 . The flap locking device 360 may include a handle 361 and a locking surface 362 . In addition, the frame part 120 may include a lock shaft 363 thereon.

The user may control the opening of the flap 130 through manipulation of the handle 361 , the locking surface 362 , and the locking shaft 363 . For example, when the user moves the handle 361 upward, the locking surface 362 may be placed on the outside of the flap 130 so as not to interfere with the movement of the flap 130 .

The user can control the role of opening and closing the flap 130 by controlling the handle 361 moving about the lock shaft 363 so that the lock surface 362 comes into contact with the flap 130 .

As another example, when the user moves the handle 361 downward, the locking surface 362 is positioned on the upper surface of the flap 130 , thereby controlling the flap 130 not to be opened.

Therefore, when there is a risk that the flap 130 is opened by the pressure of exhalation, such as when a strong wind blows outside, and there is a risk that fine dust may enter the inside of the mask 100 from the outside through the flap 130, the user locks the flap The flap 130 can be controlled to close via the device 360 .

The user may close the flap locking device 360 if people can feel the exhalation breathing of the mask 100 wearer or cause inconvenience to others because people are extremely dense, such as in the subway. Therefore, the user can use the disclosed example of the mask with a function similar to that of a general mask without the flap 130 .

In addition, when the flap 130 is opened with a weak exhalation, a fine air opening structure (not shown) such as an insect screen is installed in the flap protection part 170 ) or may be additionally installed inside the frame unit 120 .
