Description

Plate Valves and Masks

The present invention relates to a valve and a mask in which the valve is used, and more particularly to a plate-like valve which is preferably applied to a mask as a thin plate that is well bent, a mask material to which the plate-shaped valve is applied, and a mask using the same. It can be used as an intake valve by overlapping the entire or most of the area of the back filter medium or by binding to a partial area of the mask.

Various valve technologies exist, but it is surprising that there are no valves that can be flexibly applied to filter media such as masks because they function as thin plates and bend over the entire area.

(Patent Document 1) Japanese Unexamined Patent Application Publication No. 2006-256405 (September 28, 2006) The draft flap structure is a structure in which the valve member can be rotated downward by gravity by a hinge above the valve member and closed. The construction is not only limited, but also different from the present in that there is no support plate that functions as the present application.

(Patent Document 2) Japanese Patent Application Laid-Open No. 2001-178837 (July 03, 2001) An assisting device such as a respiratory humidifier and a mask is a configuration of a mask that allows inhalation of moisturized gas, and a moisturizing substance does not come into contact with the skin. It is a barrier to prevent it, and there is no support plate holder. Notched through-holes formed in the seat are simply air passages, and air can leak between the notches, and if the surface of the moisturizer compartment is uneven or the spacing between the moisturizer and the moisturizer compartment is common. Air leaks from the notch to the valve not to be able to exert the function, as well as the notch portion of the seat and the level can vary depending on the pressure difference of breathing is difficult to see as a valve.

(Patent Document 3) Korea Patent Office Registration No. 10-1447903 (September 30, 2014) The laminated nose device is composed of a plurality of flap valves made of a flexible material. It is a device that limits the function of the ground valve.

(Patent Document 4) Korean Patent Office Application No. 10-2012-0013514 (February 10, 2012) The exhaust valve for a mask is a conventional valve in which an elastic valve member is actuated to an air vent, and has a thin plate even when it is connected upside down. Is different from the configuration and principle of the valve.

In order to solve the problems as described above, the present invention is able to function as an intake valve while evenly exhibiting the effect of filtration in almost the entire area of the filter medium, such as a mask, and made as thin as the thickness of the mask material but without flexibility Functions can be demonstrated in materials, washing can be performed like masks, and production can be performed simultaneously in the mask automation production process.This protects filter materials such as activated carbon filters and static electricity-containing filters from moisture to be coated. It is intended to maintain and to produce a thin exhaust valve with a very simple production process.

1 illustrates a valve material laminated on an activated carbon filter 300.

Activated carbon is coated on the support layer 321 such as cloth or mesh to form the activated carbon layer 322, and an activated carbon protective layer 320 formed of the support layer and the activated carbon layer is formed, and a valve material such as a thin sheet of synthetic resin piece ( 310 is sequentially overlapped and a portion of the layer contacting the activated carbon protective layer is bound to form the activated carbon protective layer fixing stand (313-1) and the other side can be heard by the air intake and closed when the air is released to prevent air backflow To function as a valve, in order to protect the valve while operating in a certain space, the valve guard strip 332 of the linear shape in the same direction as the valve member is to cover the valve.

2 integral valve 311 is a modified form of the valve of FIG.

Connect the valve materials such as thin synthetic resin to each other and fold them sequentially so that some surfaces overlap with zigzag, and form a through hole 312 on the overlapped bottom surface to allow air to pass through, and attach the non-overlapping part of the bottom surface to the activated carbon protective layer to activate the carbon The fire protection floor fixing unit 313 is provided. As shown in Figure 3, the valve retainers may be applied.

3 is an unfolded state of the integral valve 311 of FIG. The through hole 312 is formed on the side of the overlapped valve of the sequentially folded contact with the activated carbon protective layer. The valve material upper surface fitting part 317-2 is an example in which an adhesive strip is formed on at least one of the left and right sides of the V shape where the valve on the upper surface of the valve is overlapped and bonded. ) Is an example in which an adhesive strip is formed on at least one of the left and right sides of the V-shape where the valve at the bottom of the valve is overlapped, and the valve top fixing plate 317-3 has a bonding point at several places above the valve. Formed to form a bonded valve is to be bonded, the valve seat bottom fixing plate (317-4) is to form a point of adhesion to the overlapping bottom of the bottom of the valve to make the folded valve bonded.

4 is a two-sided valve 311-1, in which the valve member first surface 310-3 is moved slightly to the left than the valve member second surface 310-4, which is the rear surface, and is bound to each other. The valve member 1 surface 310-3 and the valve member 2 surface 310-4 are bound by four horizontal and one vertical valve restraints 317. When used as an intake valve, the activated carbon protective layer fixing stand 313-2 is bound to the activated carbon layer on the outer side from the respirator of the valve member 2 surface 310-4, and the air passing through the activated carbon layer or the filter medium is sucked in the valve. After passing through the second surface through hole 312-1, air is sucked into the valve material one surface through hole 312-2. When the air is inhaled like other valves of the present application, the valve member 2 surface 310-4 is not lifted much from the filter media due to the activated carbon protective layer fixing stand 313-2, and the valve member surface 310-3 is As you hear a lot, it passes through the valve member 2 surface through hole and valve member 1 surface through hole. On the other hand, to release air from the valve member 1 surface (310-3) of the two-sided valve 311-1, the valve member surface 310-3 and the valve member surface 2 (310-4) are in contact with each other. If the active carbon protective layer fixing stand 313-2 is also formed to have a large area, it is useful to reduce the lifting of the valve face 2 side 310-4 during air intake. It may be desirable to form not wide because the restriction is widened, can be appropriately determined according to the use and material, etc., it is also possible to form in many places in a small shape.

The effect of the filtration on the entire area of the filter medium, such as a mask, is evenly shown to function as an intake valve.

As the thickness of the mask material shows the function of the valve, it can be conveniently used for packaging distribution and utilization.

The flexible and thin material allows the valve to function.

Regardless of the direction in which the valve is engaged and used, the function of the valve can be exhibited.

It is a structure that can be washed easily without brushing every corner of valve recombination.

Valves made of synthetic resin injection structures are not combined into a separate production process, and can be operated simultaneously in automated production processes by the bonding method, such as ultrasonic bonding, which reduces production costs and enables multiple uses. Can be.

Since it is not a valve made of injection structure, it is advantageous in distribution management because of its small volume.

Such a valve can be used so that the effectiveness of the filter medium adversely affected by moisture, such as an activated carbon filter and an electrostatic-containing filter, is not reduced.

It is also easy to use not only as the intake valve but also as the exhaust valve for a part of the mask material.

A valve, comprising: a support plate having a network structure through which air flows, and a valve recombination fixed to the support plate, wherein the valve recombination sequentially stacks valve pieces on the support plate such that some surfaces overlap each other, and contacts the support plate. It is provided with a support plate fixing for binding a partial area of the valve member pieces, when negative pressure is formed on the valve recombination side, air flows between the valve member pieces through the support plate, and when positive pressure is formed on the valve recombination side, the valve member pieces are mutually directed toward the support plate. It is attached to block the flow of air, it is a plate-shaped valve made of a part of the mask material.

In addition, the valve includes a support plate of a network structure through which air flows, and a valve recombination fixed to the support plate, wherein the valve recombination is gradually folded and folded in such a manner that some surfaces overlap with the zigzag from the right side to the left side of the valve material. It is provided with a plurality of through holes, and the support plate is fixed to the side to see the through hole of the valve recombination is fixed to some or all the area, and when the negative pressure is formed on the valve recombination side through the support plate through the air through the holes When the positive pressure is formed on the valve recombination side, the valve members adhere to each other toward the support plate to block the flow of air, and the valve member is a plate-shaped valve.

In addition, the valve includes a support plate of a network structure through which air flows, and a valve recombination fixed to the support plate, wherein the valve recombination is a valve restraint for allowing a portion of two overlapping valve members to be fastened and a non-overlapping position. With a plurality of through holes,

And a support plate holder for fixing a part or all of the area of the valve material in contact with the support plate. When a negative pressure is formed on the valve recombination side, air flows through the support plate and through the through holes, and when the positive pressure is formed on the valve recombination side, the valve members are supported. It is attached to each other to block the flow of air, it is a plate-shaped valve made of a part of the mask material.

The support plate may be a filter material or may be used for respiratory protection by stacking the filter material and the support plate in one order on one side of the valve recombination.

In the plate valve, the support plate may have higher shape retention than the valve member.

The valve member bound to the support plate may be higher in shape retention than the valve member bound to the valve member.

The mask material may be used for respiratory protection by the support plate being a filter medium or the filter medium and the support plate in one order on the side of the valve recombination.

The mask material is to position the valve recombination from the respirator inward, the edges are bound to each other, the harness is provided on one side may be a mask material.

The mask may include any one or more of an activated carbon protective layer or an electrostatic filter layer as a filter material.

The mask may be fastened at the same position in the thickness direction in which the support plate holder and the valve holder are overlapped with each other.

The mask may further comprise a valve guard covering the valve recombination.

The mask member may be provided with an exhaust valve having a rim attached to each other, having a harness on one side, and a valve recombination bound to an outer side from the respirator on a predetermined area of one side of the mask member.

The exhaust valve may be bound so that air does not leak where the predetermined area of the mask material is removed.

In Figures 1 and 2, the plate-shaped valve may include a valve restraint to allow a portion of the valve member to overlap.

Valve recombination is a flap may be provided at the end of the air flow between the valve member.

The filter medium or filter medium layer may include pulp, resin, various fabrics, nonwoven fabrics, cotton, gauze, activated carbon filters, and electrostatic filters such as ultra-static filters, gas masks, etc., and may be used by moistening. One or more of other air or water The use of the activated carbon filter, the supercapacitive filter, and other filter media of the present application can be applied mutatis mutandis, including ordinary materials capable of filtration. In order to filter the polluted air and water, it is possible to use thin, thick, or two or more layers in consideration of the air suction resistance and the effectiveness of the filtration.

The support plate is formed in the form of gauze or various mesh structures such as squares or hexagons made of metal or synthetic resins through which air or water flows, or metal or synthetic resins through which air or water flows, or similar to a net. It may be as described above or may have a network structure including a three-dimensional structure and a chain structure. The size of the network of the network structure is considered to be formed so large that the valve recombination of the present application to support the valve function so as not to limit the function manifestation. The support plate is made of a bent material, so that the function of the valve can be exerted even if it is bent by applying to a mask or the like. At this time, in order to keep the air flow at an appropriate level even in a curved situation, considering the length and width of the valve member, the length and width of the valve member folded, the interval between the valve holder and the thickness of the valve member and the degree of elastic force of the valve member You can also use different materials.

It is preferable that the support plate is made of a material having high shape retention, the valve material on the side that contacts the support plate is made of an intermediate material, and when used as an intake valve, the inner valve material of the support plate is made of a low shape retaining material. In the case of thick cloth such as fire protection layer, if the change of the shape that is moved to the respirator when breathing is less than the valve material, it can be expressed as more shape maintainability. Even though the shape maintainability is the same, the support plate side protrudes convexly. If the support plate and the filter medium are overlapped with each other, such as a cup-type mask or a mask that maintains a certain shape, the valve function can be displayed even if the overlapping order is made of the filter material and the support plate or vice versa. The support plate holder may be stuck to the filter media. All.

The mask material can be made by adding a valve recombination, a filter material and a support plate if necessary to block the face portion around the nose like a normal mask so that the filtration protection function can be exerted on the entire area of the material. In addition, it can be added, the edges can be sealed or fastened, and the airtight or non-aired edge seals, or separate exhaust valves or other structures combined, can be protected even if the filtration is limited in the total area of the filter media. Can be expressed. This is because the part where the edge seal and the separate exhaust valve or other structure are combined may not be regarded as a part of the filter medium. By attaching a harness that can hang the mask material behind the ear or the head, and binding the rim, it can be a mask, and the exhaust valve can be positioned on one side of the mask material like a normal mask, and at this time, the valve of the present application can act as an exhaust valve. It is possible to bind.

The size of the through hole takes into account the amount of air used for one-time suction and the function of the valve, and it is possible to cut into various shapes such as square, round, other polygons, +, T, T, etc. Since air is also passed through, it is referred to as a through hole, it is also possible to form such a long hole over the valve restraint. Thickening the valve material or narrowing the gap between the activated carbon protective layer and the valve guard may prevent the valve from turning over without securing the valve to the activated carbon protective layer, but it may be desirable to make it as thin as possible. Valve material can be manufactured by using synthetic resins including PE, PP, OPP, HD, LDPE, PVC and various vinyls, rubber, latex, silicone, coated paper and other common materials, or folding or molding them. It is not only rectangular or straight but also curved.

Activated carbon layer of activated carbon filter includes powder or granules coated on cloth, non-woven fabric, paper, cotton, etc., laminated in multiple layers, invaded, or composed only of activated carbon layer itself such as activated carbon fiber. Includes physical and chemical filtration capabilities, such as canisters.

In FIG. 1, the activated carbon layer 322 and the support layer 321 may be coupled to the valve in opposite directions, and may be utilized by adding a protective material or a filter material to the activated carbon filter, and using a purifier or thick activated carbon. In some cases, such as fibers, the support layer is unnecessary.

When used as an intake valve, the outside air flows through the valve recombination with at least one of the filter medium and the support plate to the inside of the respirator.

In particular, the adsorption of static electricity such as powder activated carbon filter and supercapacitive filter may be easily reduced by the moisture of the breathing. Therefore, the exhaling breathing is discharged between the mask and the face part or through a predetermined valve of the filter layer. It may be desirable to configure it to enter the filter layer. To this end, even if a gas exhaust valve structure made of rubber or silicone is attached to the mask, some of the moisture is circulated to the place where the exhaust valve is not formed, thereby limiting the efficacy of the mask. Additional processes, increased manufacturing costs, and limited storage and ease of use.

When used as an intake valve, the valve guard 330 on the inner side of the respirator protects the valve while reducing excessive swelling of the valve member 310 during air intake and restricts the valve from directly contacting the face. At this time, the interval between the valve guard 330 and the valve member 310 may be several mm or less in consideration of the volume and ease of breathing and the degree of noise generated during the air flow, even if formed in close contact with the air flow. Inflated by pressure, the function can be exerted. In addition, it is possible to increase the height of the valve guard rim 333, to thicken the whole or part of the valve guard strap 332, or to form dozens or hundreds of small protrusions. It is possible to use it in accordance with the degree of swelling and other swelling by making a mesh shape, forming a line in the transverse direction opposite to FIG. 1, adjusting the spacing, and the like. The parts in which the valve materials come in contact with each other should be made of a material with high adhesion, and the normal parts such as non-woven fabric, cloth, gauze, mesh materials, etc. can be applied and coated with a comfortable material. In particular, in the case of the exhaust valve, as a means for absorbing the smell of breathing may be used to bind or remove the filter medium.

The valve refitted on the support plate can be provided with a flap to improve the sealing force and durability of the valve. The flap extends the thinner valve member by a predetermined length at the last end of the flow of air between the valve members. The length of the flow is made longer, or it becomes thinner toward the last end of the air flow between the valve members. In this case, it can be expressed as a flap formed in the valve member, and it is an extension of the valve member or a separate flap member. Can be configured. The length, area, and shape of the flap should be considered to be about 1 cm or less if the length of the flap is extended to a thinner valve member in the direction of air flow, taking into account the sealing requirements, the weight, durability, and material. Do. In the flap of FIG. 4, a flap member having a smaller hole than the valve member is formed at the edge of the through hole of the valve member, which is attached to the valve member, or a single flap member is attached to the valve member to form a smaller aperture than the valve member. Overlapping is possible, and at this time, the flap material may be added to the valve member to be referred to as one sheet or two sheets.

Activated carbon protection layer is to hold the valve member on the side of the activated carbon protection layer when the intake air flows by allowing the valve material to bind to the activated carbon protection layer to open the valve, the activated carbon protection layer can be a support plate, the activated carbon protection layer is a support plate Since it performs the function of, the activated carbon protective layer anchor may also be referred to as a support plate anchor.

The valve restraint among the stators is a part of the valve restraint which is bound to each other in the range through which air flows through the overlapping side of the valve material, and is intended to maintain the shape stably without overturning the valve and to facilitate the production process. If the material is made of material that is capable of maintaining a minimum shape, or if it is formed to be bent like the shape of the face part, the valve restraint may not be applied, and the outer edge is sealed or the inside is considered in consideration of anti-fog and breathing convenience. If the secondary parts such as exhaust valves are bound, the area of the filter medium is narrowed, and thus the function of the valve can be made of a thinner material. The valve restraint includes a valve bottom fixing part, a valve upper part fixing part, a valve upper part fixing part, a valve lower part fixing part, and the like. The valve restraint may not be necessary if it is used with the valve guard inside. The valve material can be manufactured with a thinner material without flexibility by utilizing the valve restraint and the support plate restraint and the rim and the folding part of the mask.

In the method of forming the valve restraint, when the valve member is laminated or the valve member is folded in a sequential manner, a plurality of lines of adhesive are applied in a band shape to a portion where the valve member overlaps each other in the direction in which the valve member is sequentially formed. When sequentially arranged as shown in FIG. 1 or zigzag-up as shown in FIG. 2, the possibility of being glued and flipped over each other is eliminated, and the activated carbon protective layer holder 313 regardless of the position of the through hole within the range where the valves overlap each other (313) The advantage of forming a) is generated, and air flows into the space between the band-shaped valve holder and the valve holder.

In addition, this form is a shape in which the valve repositioning station and the activated carbon layer fixing station in the valve member, the adhesive of the portion of the valve member does not overlap the valve member to bind the valve recombination to the activated carbon protective layer. If the valve holder is formed inside the valve member can be formed where the valve member overlap each other.

In this case, the narrower the binding interval, the smaller the lift level of the valve. At this time, the valve protector may emphasize the function of protecting the durability of the valve rather than the function of securing space. At this time, if the binding portion is wide, it may be undesirable to widen the area of the activated carbon protective layer to be filtered.

Although applying a strip of adhesive on the inside of the valve, that is, on the side of the valve protector, it is possible to control the degree of swelling while reducing the valve inversion similarly, but it is possible to control the swelling of the valve by Since the function may be limited, the upper surface of the valve may only bind the portion where the valve overlaps each other.

A portion of the valve upper contact portion fixing portion 317-2 and the valve lower portion fixing portion 317-1 bonded to the strip may be applied to the entire length of the valve. If the upper surface of the valve adjacent to the upper part is formed to have a narrow gap, the valve swells and closes again when inhaled, as well as less noise, resulting in less rejection of wearing. It may be desirable to avoid this, and the lower bottom fitting may similarly be used, while under conditions such as when the valve guard is used, the impact of the band gap that is binding may be less, where only the outer rim is sutured. Even if it is a valve lock station.

The fixing plate can be formed by binding the support plate fixing plate and the valve fixing plate to the same position in the thickness direction with each other. When shortening the process by using ultrasonic bonding, etc., if some fixing stand is formed in the place where the hole is formed, only two places may be bonded in a straight line, but if the fixing stand that matches the three binding points in other places is used in many places, Fixtures have been applied, and even if they are not named, the use of the support plate holders and the valve re-lockers may appear to be the locker if the positions are coincidentally or necessarily coincident with each other.

Although the direction in which the valve pieces are stacked may be maintained in one direction, depending on the shape of the valve material and the overlapping area when the valve pieces are stacked, the valve pieces may be shifted in the left and right directions rather than horizontally. It is apparent that the shape change, such as causing the stacking direction to shift according to the direction in which the ash is folded, falls within the scope of the present application.

When the overlapped part of the synthetic resin pieces are used as shown in FIG. 1, the process of managing and binding the synthetic resin pieces may be difficult or a process may be added. One-piece valve is to improve this as a synthetic resin material is connected to each other, as shown in Figure 2 to fold in a zig-zag to overlap a part, it is possible to form a through-hole 312 in the overlapped lower surface to allow air to pass through. The overlapping lower surface of the aperture is the aperture 312 of FIG. 3, and it is also possible to form the apertures on both sides, including the surface of the folded upper portion, that is, the surface overlapped and not visible from above. The through hole can be formed only in the upper surface of the through hole formed in the two sides on the basis of the folded portion of Figure 3, when forming the through hole in the lower position when the bottom end of the non-overlapping end in the usual way to bind Activated carbon protective layer fixing stand 313 may be formed in part or all of the back, and may be bound. The through hole may be formed in a fixed extra space, and the area of the valve member may be fixed to the activated carbon protective layer to increase the size of the through hole. It is possible to make almost the entire area except for this, and in this case, the entire area of the valve material except the through hole may be bound to the activated carbon protective layer, and in this case, it may appear that a hole is formed in the activated carbon holder, and the activated carbon protective layer holder may be The non-overlapping whole makes the 312's vents airy but folds across the other side. In consideration of the fact that air is difficult to flow, it is possible to determine the size, location, thickness of valve material, and material flexibility by considering air communication requirements, air intake resistance, and air flow through the entire filter medium. . In the shape of FIG. 4, the size of the through hole and the area where the valve member is bound to the activated carbon protective layer may be similarly applied.

The present application is to perform the function of filtration almost uniformly in almost the entire area of the filter medium, which is the part where the filtration function can not be exerted as much as the area of the support plate holder is in contact with the filter medium, Even if the air flows in the part at the oblique angle of the filter medium, the function of filtration can be shown in the whole area.If the net of the plastic support plate or the structure of the filter medium is rounded and the valve is attached, the valve functions in the whole area. It is expressed here, and the exhaust valve of the gas mask is contrasted with the valve function by binding to a partial area of the air impermeable material.

When the valve of the present application is a mask applied as an exhaust valve, the support plate is bound toward the respirator at a predetermined partial area of the mask material in the direction opposite to the intake valve. When the valve of the present application is used as an exhaust valve, the air exhaust resistance is mainly related to the area through which the air flows through the valve, and in detail, the area of the entire valve and the size of the through hole or the gap of the valve member, the area of the support plate holder and the valve holder, The flexibility of the valve, the material, thickness, and the degree of opening of the valve due to the state of binding to the mask material. The valve can be appropriately formed according to the intended use, and the air intake resistance when the valve of the present application is used as an intake valve is the same principle. It can be formed by applying, and can be applied to prevent the valve from overturning. In consideration of the fact that the area of the exhaust valve becomes wider as the area of the exhaust valve becomes wider, it may be undesirable to form a predetermined appropriate area. In order to simplify the manufacturing process, it is possible to attach the exhaust valve to the mask material, but the air flow resistance is increased. It can be flexibly determined by forming a position about the center of the middle part, or forming a long side to the left or right at a predetermined height when worn, so that it can be separately settled, partition the mask rim or the gap of the mask, or other various forms. It is also possible to bind together when making a binding, and to make the valve of this application use an intake valve only in the part using the filter medium affected by exhausted moisture. Exhaust valves can be attached in such a way as to prevent leakage of air using conventional techniques, such as binding parts where a part of the surface is superimposed where the predetermined area of the mask material is removed, or tapering down the exhaust valve material. The same applies to intake valves.

Although the edge of the valve recombination is not sealed, for example, when the mouth is pushed or in close contact with a pipe, the valve member in contact with the mouth and the pipe may be in close contact with each other to exert the effect of the valve on the entire area of the air passage through the mouth and the pipe. However, if the edge is not sealed, air may leak between the valve members in various situations, or between the valve recombination and the filter medium. Therefore, the edges of the various mask material components of the present disclosure are preferably bound for the maximum possible valve function.

It is also within the scope of the mask herein to cover the head with a filter hood and form an air impermeable viewing window, such as a protective hood.

Bonding can be performed by conventional techniques such as thermal bonding, high frequency, ultrasonic waves, adhesives, taping, sewing, etc., and common methods such as bonding, sealing, sewing, and binding for attaching valve pieces to each other or fixing valves can be used interchangeably herein. In the case of taping or the like, a fixing stand may be provided on at least one surface of both sides touching each other, and this is the same as in the case of thermal bonding, and the materials and functions of the various components of the present application and the concept and method of concept are matched to the purpose of the present application. It is apparent that the present invention, such as used interchangeably.

The present invention can be applied to a plate-like valve which is preferably applied to a mask, a mask material to which the plate-shaped valve is applied, and a mask using the same.

In particular, it can be used as an intake valve so that the efficacy of a filter medium adversely affected by moisture, such as an activated carbon filter and an electrostatic-containing filter, is not reduced.

In addition, when using as an exhaust valve in a part of the mask material, the production cost is reduced, and the volume is small, which is advantageous for distribution management.
