Description

Mask with lower ventilation structure {MASK HAVING LOWER VENTILATION STRUCTURE}

The present invention relates to a sanitary mask, and more specifically, to a mask that has improved adhesion to the face, ensures internal space, and has a ventilation structure that can control the inflow and outflow direction of breathing.

A mask refers to an item that covers the nose and mouth for health and hygiene purposes to prevent inhalation of germs or dust and scattering of saliva.

These masks are usually produced using gauze or non-woven fabric, and are known to have been used in earnest since 1919, when the Spanish influenza, a common cold, became prevalent around the world.

In other words, it was used from the beginning to prevent the inflow of cold viruses or bacteria, but it is gradually being used to prevent the inflow of cold air or to prevent dust. In addition, recently, due to the increase in fine dust and the impact of the pandemic caused by the virus, wearing masks has become a daily routine for all of humanity.

Typically, masks are manufactured on a standardized production line, so the size and shape are constant, and such ready-made masks are generally purchased and worn. However, as wearing a mask becomes a daily routine, the inconvenience is becoming more and more recognized. It causes not only a stuffy problem due to poor breathing, but also discomfort in conversation. In particular, the mask does not properly cover the mouth area even during exercise, conversation, or breathing, causing discomfort in the seat. You can find common problems that occur when you deviate from the .

Korean Public Utility No. 20-2020-0001161 proposes a mask whose length can be adjusted to increase adhesion to the face to solve these problems. Figure 1 is a perspective view of this improved mask of the prior art, which will be examined in detail.

A mask body (10) whose circumference is in close contact with the face, an earring band (20) with both ends (21) fixed to both side ends (10a) of the mask body (10), and the mask body (10). It is configured to include length-adjusting cutouts 30 for adjusting the length of the earring bands 20 formed on both side end portions 10a. The length-adjusting incisions 30 are formed on both side end portions 10a of the mask body 10, and when necessary, the length-adjusting incisions 30 are cut using a cutting means such as a knife, The length can be adjusted by wrapping the end portion 11 of the mask body 10 by inserting the middle portion 22 of the earring band 20 into the cutout 30 for length adjustment.

Many attempts have been made to strengthen adhesion by adjusting the length of the string leading to the ear area. Although pulling it from side to side contributes to strengthening the adhesion, due to the limitations of the structure and material of the mask made of non-woven or fibrous material, it is difficult to cover the face. Breathing leakage occurs due to uneven adhesion, and there is a limitation in controlling the movement of the mask up and down during conversation or exercise.

In addition, because the curves of the nose area in particular have complex shapes, such weak adhesion causes upper respiratory outflow and fogging, which leads to inconvenience during use.

Conventional disposable masks tend to stick to the face and retain moisture, which poses a problem of not only inconvenience but also discomfort when worn, especially in light of the recent increase in the population of men as well as women wearing makeup. There is.

Meanwhile, as wearing masks becomes routine, inconveniences resulting from long-term use are discovered, a representative example of which is the problem of poor conversation. This is due to the fact that the mask itself attenuates sound waves, but rather, it is known to be because it blocks the visual part of recognizing both sight and voice by looking at the shape of a person's mouth when talking. In addition, since it covers more than half of the face, the problem of covering up makeup and the problem of skin irritation due to the constant wearing of frictional cotton or non-woven materials are also raised.

The present invention was developed to overcome the problems of the prior art described above, and the adhesion to the face is strengthened, so that the isolation function from the outside is excellent, and the direction of ventilation is directed downward, so that convenience and comfort in use can be improved. The purpose is to provide a mask with a structure.

The present invention to solve the above problem includes a main body 100 arranged to surround the nose and mouth, a pair of hook parts 110 extending to both sides of the main body, and a lower side of the main body when worn on the face. A mask having a lower ventilation structure including a lower ventilation part 120 that forms a space in the mask to allow internal and external air to flow, and a filter part 200 that is arranged to cover the lower ventilation part and filters the air. to provide.

Preferably, the main body is provided with a fastening structure in which both sides of the filter part are caught on the inner surface, and when the hook part of the filter part is caught on the ear and worn on the face, the chin area and the lower part of the main body are pulled to both sides from the fastening structure portion. It can be attached closely to the inside.

It is preferable that the main body and the hanger are made of silicone and manufactured by an integrated injection method. The material may be transparent.

Additionally, the fastening structure may be a protruding fastening part 140 that protrudes inward to be inserted into the insertion hole 210 formed in the filter unit.

The main body has a locking protrusion 161 coupled to the filter, and a folded locking portion 160 that is folded from the bottom to the top and has a folded surface 162 whose width widens toward the outside. It has an insertion hole 210 formed on both sides with the lower ventilation part in between, into which the locking protrusion is inserted and locked, and the folded surface can be pressed forward to come into close contact with the face.

Additionally, the main body may be provided with a lower reinforcement portion 151 that protrudes inward to correspond to the contour of the lower face and adhere the filter portion.

Due to the configuration of the present invention described above, the space inside the mask can be guaranteed in any environment, so it does not cause discomfort in breathing and allows natural movement of the mouth, which has the effect of increasing convenience even in regular wearing. there is.

In addition, since it is possible to accurately adhere to the face and induce ventilation downward, fogging can be blocked at the source, and breathing is accurately directed to the outside, which has the effect of increasing stability when worn.

In addition, since the filter can be replaced as needed and the main body can be used semi-permanently, it is highly economical. In order to construct a separate filter part, only an insertion hole needs to be formed in the existing non-woven filter, so the economic advantage will be greatly improved. You can.

In addition, by adopting a silicone material that is harmless to the human body and minimizes skin irritation, the occurrence of problems is significantly lower than that of conventional disposable masks even when worn for a long period of time.

In addition, since it is possible to use a transparent material, conversation becomes smoother, and since the impression and makeup are visually visible to the other person, there is a side effect of increasing likability.

Hereinafter, a mask having a lower ventilation structure of a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments described below are merely intended to provide a detailed description so that a person skilled in the art can easily implement the invention, and this does not limit the scope of protection of the present invention. doesn't mean

In the following description, when a part is said to be 'connected' to another part, this includes not only the case where it is directly connected, but also the case where it is connected with another part or device in between. In addition, when a part is said to 'include' a certain component, this does not mean excluding other components, but may include other components, unless specifically stated to the contrary.

The present invention basically provides a body portion arranged to surround the nose and mouth area and made of a silicone material, a pair of hook portions extending on both sides from the body portion, and a flow of air between the lower side of the body portion and the chin. Provides a mask including a lower ventilation portion constituting a space for.

In the present invention, the mask is used to prevent foreign substances such as dust, viruses, and bacteria from entering the nose or mouth, or from spraying saliva or snot. Basically, it can be provided in a form that hangs over the ears from both sides. The shape, material, use, and arrangement of the mask do not limit the concept of the present invention.

In the following description, the area surrounding the mouth of the main body will be defined as rear and medial, and the direction facing the external air will be defined as anterior and external.

Figure 2 is a rear view for explaining a mask having a support frame according to the present invention.

The main body 100 is shaped to surround the mouth and nose, and it is sufficient to isolate the space between the outside and the mouth area. According to the concept of the present invention, the main body 100 is preferably made of silicone material. When the main body 100 is made of silicone material in this way, it can maintain its shape to a certain extent and has elasticity, so it has excellent adhesion to the body. The shape of the main body 100 is optional, but it is better to provide space around the mouth and cheeks to allow some movement.

In the embodiment of the present invention, it is basically illustrated in a form that has hooks 110 that can be hung on both sides of the ear. Considering productivity and economic efficiency, it is preferable that the main body 100 and the hanger 110 are formed by an integrated injection method. However, in some cases, the hook 110 may be coupled or attached to the main body 100 in the form of a separate wire.

It would be desirable for the entire mask to be made of silicone, and elastomers, etc., can be considered equivalent to silicone as long as they have similar physical properties and flexibility to silicone.

If silicone material is used in this way, skin irritation is not only minimized, but it can also be made transparent, so detailed aspects such as the shape of the mouth and facial contour as well as skin tone can be seen from the outside. Note that this provides the advantage that the smoothness of conversation is not significantly different from the case of not wearing a mask compared to the case of hearing only the voice because the shape of the mouth can be confirmed.

In addition, aesthetic satisfaction can be improved because the entire face can be seen and the effects of color makeup, etc. are visually recognized from the outside.

Unlike a typical mask, the main body 100 is made of an airtight material, so a structure for ventilation is required. In the concept of the present invention, the ventilation structure is configured on the lower side and a lower ventilation portion 120 is defined.

When worn on the face, the lower ventilation part 120 forms a space under the chin and the main body 100 to allow internal and external air to flow. Since the breath discharged from the user's mouth or nose through the lower ventilation unit 120 is guided to the lower part and discharged to the outside, and the outside air can be introduced again from the lower part according to the inhalation, no air flow occurs on the upper side of the nose. . Please note that this can fundamentally prevent fogging on glasses, face shields, etc.

The filter part may be arranged to cover the lower ventilation part 120, and the filter part will be described later.

A fastening structure for fixing and supporting the filter part may be formed in the main body part 100 adjacent to the lower ventilation part 120. In one embodiment of the present invention, the fastening structure consists of a protruding fastening part 140. Explain an example. The protruding fastening portion 140 may be formed in a wedge shape whose radius becomes wider as it goes inward, and is inserted into an insertion hole such as a hole or incision line formed in the filter portion to perform a supporting function on both sides. However, the fastening structure is not limited to the above examples, and known elements for coupling between various members such as snap buttons, hooks, bolts, grooves, Velcro, adhesive tape, and gel pads may be applied.

In the present invention, since the main body 100 is entirely made of an elastic silicone material, elastic deformation occurs in accordance with the facial contour when worn. In order to enhance adhesion, the main body 100 may be narrower in the width direction than the overall outline of the face and may be formed in a shape that protrudes forward. Accordingly, as it is worn according to the facial contour, it is closely adhered in a form that opens to both sides, and the protruding fastening portion 140 will provide tension in the outer direction on both sides while the filter portion 200 is caught. Therefore, when worn, the filter part receives a force pulled to both sides and comes into close contact with the chin area and the lower inner surface of the main body 100, thereby ensuring filtration performance for ventilation.

Meanwhile, as described above, due to the nature of the main body 100 being made of silicone, it has higher flexibility compared to hard synthetic resin materials such as PP or PE. Therefore, it is preferable that a structure for maintaining the shape and reinforcing rigidity is formed, especially on the upper and/or lower side of the main body 100. In consideration of this, the upper bent portion 130 is formed at the upper end of the main body portion 100 in a rearward bent shape. The upper bent portion 130 may be shaped to cross the facial contour on the upper side of the nose and ensures the stability and adhesion of the overall structure.

In addition, a rib-shaped lower reinforcement portion 151 that protrudes approximately inward with the lower ventilation portion 120 interposed may be formed in the lower portion of the main body portion 100 where the lower ventilation portion 120 is formed. The lower reinforcement part 151 supports the filter part on the inner surface and allows the lower part of the main body part 100 to be brought into close contact with the outline of the face. In some cases, it may be considered to extend across the lower ventilation portion 120.

Figure 3 is a side view showing a state in which the mask having a lower ventilation structure according to an embodiment of the present invention described above is worn on the face.

The main body portion 100 mainly surrounds the nose and mouth portions to form a space inside, and the filter portion 200 is disposed in the lower ventilation portion 120 as described above.

This filter unit 200 is coupled to the main body 100 by protruding fastening parts 140 on both sides, and approximately both sides and the upper side are disposed on the rear side (inside) of the main body 100, but the lower center is exposed to the outside. Please note that it is In the exposed area, the lower flow (α) is guided downward.

Various types of filter members made of non-woven fabric, synthetic fiber, cotton, metal material, etc. may be applied to the filter unit 200. In this regard, since known ones can be applied, specific examples will be omitted. However, this filter part is fastened by a fastening structure, but it is desirable to be made of a material with high flexibility because it must respond to the deformation of the main body part 100 made of silicone and adhere closely to the facial contour. Considering productivity and efficiency, non-woven fabric is used. It may be made of a material containing:

As shown, the hook part 110 is caught on the ear and pulls the main body part 100 to both sides to adhere closely to the facial contour, and the protruding fastening structure is used to support the correct shape and maintain the position of the filter part 200. The fastening portion 140 provides pulling tension to both sides.

The upper side of the main body 100 is covered so as to cross the upper side of the nose and the upper cheek, and the upper bent portion 130 strengthens adhesion. Additionally, a lower reinforcement portion 151 may be further disposed on the lower side of the main body portion 100 where the filter portion 200 is disposed to enhance rigidity and adhesion.

Figure 4 is a rear view of a mask having a lower ventilation structure according to an additional embodiment of the present invention.

An upper bent portion 130 is disposed on the upper side of the main body 100, and in one embodiment, a lower reinforcing portion 151 is formed on the lower side to provide adhesion to the face and structural rigidity at the same time. is the same as above.

In an additional concept of the present invention, a fastening structure for coupling the filter unit 200 and a structure for structural reinforcement and facial contact are configured to be folded inward at the lower portion where the lower ventilation unit 120 is disposed.

Specifically, folded locking portions 160 are formed symmetrically on both sides with the lower ventilation portion 120 in the form of a forward depression in between. The folded locking portion 160 is formed in a form in which the portion extending to the lower side of the main body portion 100 is caught upwardly inward, and the width becomes wider toward both sides, and at the end there is an insertion hole 210 formed in the filter portion 200. ) A protruding structure that can be inserted is formed.

Accordingly, the folded locking portion 160 extends symmetrically on both sides with the locking protrusion 161 inserted and caught in the insertion hole 210 of the filter portion 200 and the lower ventilation portion 120, and extends symmetrically to the chin area. It may be made of a folded surface 162 that provides adhesion to the face of the face.

The folding surface 162 has a vertical width that increases toward the outside, thereby enhancing adhesion. To this end, the folding surface 162 has a slightly wider separation distance on the inner surface of the main body 100 from the lower side to the upper side. It is preferable that it is folded in shape. Accordingly, when the hook part 110 is caught and tension is provided to both sides, the main body part 100 is elastically deformed to correspond to the contour of the face, and the folding surface 162 is pressed forward, allowing the filter part 200 to fit accurately on the face. The idea is to attach them so that they correspond.

The length on both sides of the folded surface 162 is optional, and can function as the lower reinforcement portion 151 described above. In addition, when the filter part 200 is caught on the locking protrusion 161 and worn on the face, tension is provided in an outward direction to provide a three-dimensional structure, enabling accurate support of the shape and close contact with the face.

The shape of the filter unit 200 shown is an example, and may have various shapes depending on selection, such as an oval, polygon, or three-dimensional shape.

As described above, since the present invention is made of silicone material, overall adhesion and sealing with the filter unit 200 is smoothly achieved. Note that this significantly improves efficiency compared to inserting, sewing, or gluing filters inside masks made of other non-woven materials.

The mask having the lower ventilation structure of the present invention described above allows accurate contact with the face and allows ventilation to be directed downward, thereby fundamentally blocking fogging, and breathing is accurately directed to the outside, thereby increasing the sense of stability when worn. This advantage will be further improved because space around the respiratory tract can be secured using silicone material.

In addition, since the filter can be replaced as needed and the main body can be used semi-permanently, it is highly economical. In order to construct a separate filter part, only an insertion hole needs to be formed in the existing non-woven filter, so the economic advantage will be greatly improved. will be.

In addition, with a simple structure, it is possible to adhere closely to the filter part and maintain its shape, thereby ensuring efficiency as a sanitary mask.

In the above, the present invention has been described in detail based on examples and accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the content described in the claims described later.
