Description

Manufacturing method of filter-replaceable mask structure formation {Manufacturing method of filter-replaceable mask structure formation}

The present invention is a technical field of structure forming means related to the improvement and inventive step of filtering function of a mask that can efficiently filter pollutants of yellow sand, fine dust, and ultrafine dust discharged from an internal combustion engine.

In addition to yellow dust and fine dust, heavy metal harmful substances and nitrogen compounds emitted from coal-fired power plants and internal combustion engines of automobiles running on the road are increasing, and the announcement of research results that these pollutants cause various diseases in our body is a serious social issue. Since it is emerging as an issue, government-level environmental policies for public health are being drafted and implemented.

In the past, wearing a mask was recognized as a patient image and avoided wearing a mask. And since wearing a mask has become commonplace even when going out, it has to be worn as a health product, and it has come to a situation where you have a spare.

"KF80, KF94, KF99" are limited to "quasi-drugs" as products for national health unlike the conventional mask concept, and the higher the number of the regulations, the denser the filtering cotton structure, and the higher the level of filtering function. Compared to the filtering surface of "KF80", wearing a mask with "KF94" or "KF99" makes breathing uncomfortable due to an increase in inspiratory resistance. Since you breathe unfiltered polluted air as it is, it is meaningless to wear a mask, and this causes a problem that harms the human body. has a problem of becoming an uneconomical consumable product that cannot be reused and must be discarded.

Patent Registration 10-1611952 (2016.04.06. Registration) Patent Registration 10-1867157 (2018.06.05. Registration) Patent Registration 10-1904656 (2018.09.27. Registration)

As a practical problem of the dust mask pointed out as described in the [Background Art], the inefficiency of the material that must be discarded after use and the social problem caused by being discarded in the form of garbage after use, so as to solve these problems In the material development and structure formation means for improving filtration efficiency, if the filter material of the mask is contaminated, it is easily washed and dried in running clear water, and the structure formation means is implemented so that it can be used more than once or twice. Since the realization of the purpose of developing excellent products to extend the lifespan is a realistic task,

The applicant of the present invention has registered a prior application, and sees the implementation of the purpose of the prior registration and pending technical idea. As a step forward solution to realize more concretely, the filter material's filtration function step is firstly "intermediate filtration surface capable of filtering yellow dust and fine dust" and secondly "intermediate filtration capable of filtering fine dust and heavy metals" The front and rear inner sides are separated, and between the 1st and 2nd intermediate filtering surfaces, the "separately composed tertiary filtering surface" is placed in the center of the foldable foldable type on the left and right. It is inserted into the space part to separate and filter "ultrafine dust and nitrogen compounds" efficiently so as to realize inventive step in improving the filtration function. The structure of the mask body is formed in a foldable folder type with a three-dimensional structure so that the entire face is wrapped while being closely adhered to the shape.

The intermediate filtration surface material of the primary configuration of the main body of the mask is formed of nano-fibers of synthetic fibers and utilizes a multi-layered filtration function material that can be easily washed, so that the entire face is wrapped as it adheres to the shape of the face integrally. Since the structure of the mask body is formed in a foldable folder type with a three-dimensional structure, if the filtration surface (KF94 or KF99) of the primary component of the mask body is contaminated, wash it in clear water and dry it to "for dustproof (about KF80, KF94), for cold weather, It can be reused as "for blocking droplets", etc. If the insertion filtering surface (KF80, KF94, KF99) of the secondary configuration of the mask body is contaminated, it can be reused by washing in clear water and drying, or as a new product in the insertion space of the three-dimensional folder. It is a "limited structure forming means;" characterized in that it can be easily exchanged and inserted to efficiently continue the filtering function.

The laminated part of the primary dry filter material (particle filter surface of about 10㎛) and the high-grade dry filter material (particle filter surface of about 2.5㎛) of the secondary composition combine the filtration function of the dry filter cotton and the wet filter surface. In order to be characterized in that the filtering function can be shared, a colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution is sprayed in the form of impregnation or spraying from the outside of the filtering surface to the inside of the laminate, so that the intermediate filtration of the primary configuration is performed for a certain period of time. Cotton and high-quality filtration cotton of secondary composition are "not only hygienically maintained, but also 'characterized by forming a structure so that the moisturizing function can be maintained inside the respiratory tract'",

The material of the face contact part is composed of flexible and soft functional material, so that the non-contact part with the face is closely adhered to the shape of the face to minimize the non-contact part with the face, so that the entire face is wrapped. Intermediate filter function and advanced filter function were separated to improve the progressiveness of the filtration function, and the "mask body with intermediate filter function" can be easily washed and dried and then used for "dust-proof, cold-weather, splash-proof", etc. It can be reused, and it solves the insignificant problems of ordinary disposable products by implementing a "limited structure forming means" that forms a structure so that contaminated high-quality filter cotton (KF80, KF94, KF99, etc.) can be easily exchanged. What is intended is the "problem to be solved" of the present invention.

As described above in the [Problem to be solved], among ordinary products, a filter structure is formed to comprehensively filter yellow dust, fine dust, and ultrafine dust on the filter surface of a single structure, so the "Korean Food and Drug Administration" As the density of the structure of the filter surface stipulates the appropriate standards for filtration function (KF80, KF94, KF99, etc.), contaminants below the control function can pass through the filtration surface of "KF80", so the single structure of "KF94" and "KF99" As it is an economical structure formation that cannot comprehensively satisfy "smoothness of breathing", "filtering efficiency of contaminants" and "economic efficiency of mask use" with only the filtering surface,

When wearing KF94 or KF99, which is a certification standard of the Ministry of Food and Drug Safety, "the inhalation resistance of KF94 or KF99 increases compared to that of KF80". Due to the exposure of the face, a large amount of unfiltered contaminated air can instantly flow into the body through the respiratory and oral cavity, so it is meaningless to wear a dust mask. Therefore, these situations are realistically highlighted as social issues.

However, since many dust masks are not configured to separate and filter yellow dust, fine dust, and ultrafine dust in stages, a structure is formed so that large and small contaminant particles pass through and filter at the same time only on the limited filtration surface of a single structure formation Therefore, as the fine pores are filled with large particles of contaminants, the inhalation resistance increases, causing discomfort in breathing and taking off the mask frequently, resulting in breathing a large amount of polluted air in an instant, so wearing a mask is not worthwhile. Even if a part of the filtering surface is contaminated, it is recognized as a disposable consumable product, so there is a problem as an uneconomical consumable that is discarded without reuse.

As pointed out above, the present invention is a "limited structure forming means" that can solve the common problems of dust masks, and if the filter material of the dust mask for improving filtration efficiency is contaminated, it can be reused by simply washing and drying in running water The realization of the purpose of developing an excellent product that can extend the life of the filter by improving the progressiveness of the filtration function effect by implementing the means of forming the structure and the development of the filter material so that it can

Therefore, in order to filter yellow sand or fine dust, the protective support material and the intermediate dry filter material are overlapped on the front of the dust mask body to form the primary filtering surface, and the protective support material and the intermediate dry filter material are also applied on the back of the dust mask body. The 2nd filtering surface is overlapped and the 3rd filtering surface is separately configured between the 1st and 2nd filtering surfaces, so that the space can be easily inserted or removed. formed, so that ultra-fine dust and heavy metal harmful substances and nitrogen compounds can be comprehensively filtered by the filtration function of the high-quality dry filter material of the tertiary configuration, the filter surface of the dust mask body is composed of the filter surface of the primary configuration and the secondary configuration. The filtering surface of the primary configuration was overlapped with the protective support material and the intermediate dry filter material in a separate state to form the efficiency of the yellow dust or fine dust filtering surface, and the high-quality filtering surface of the tertiary configuration formed ultrafine dust and harmful heavy metals. Since it implements the improvement of the progressivity of the efficiency of the filtration function, which enables comprehensive filtering of nitrogen compounds and nitrogenous compounds, when comprehensively comparing the known technical ideas and functional effects, the "improvement of filtration capability" can be "positive of progress". The "limited structure forming means" was formed as follows.

(1) As a structure forming means for realizing the purpose of the present invention, a protective support material and an intermediate dry filter material are overlapped on the front part of the dust mask body to form a primary filtration surface, and the protective support material and the protective support material are also formed on the rear part of the dust mask body. In melting and bonding the periphery of the 4-ply filter surface overlapping the secondary filter surface by overlapping the intermediate dry filter material,

An image with a designated "model (design) shape" at a designated location so that it can be composed of a "three-dimensional structure 'folding foldable'" at a "specified position" on the filtering surface composed of a plane. The three-dimensional folding space is perforated with an ultrasonic welding machine so that the lower part is penetrated, and the fusion bond line for bonding between materials and the straight line, dotted line, and curved line for folding are formed in the "limited structure forming means;" If the "substance of composition" is detailed in relation to the structural differentiation different from the known technology idea,

The first configuration in which the protective support material and the intermediate dry filter material combined as described above are integrally overlapped, and the protective support material and the intermediate dry filter material of the same configuration are overlapped once again in a second configuration to form the first and second configurations. Between the liver, the inserts on the left and right of the advanced filtering surface of the 3rd layer composed of three layers, including the separately formed protective support, high-quality dry filter material, and endothelium adhered to the face, are folded into the foldable central part. "Definite structure forming means" characterized in that it is inserted into the left and right spatial parts in the left and right spaces to easily withdraw the contaminated filtering cotton and replace it with a high-quality filtering cotton to realize a comprehensive filtering function more efficiently; am,

In addition, the protective support material, the intermediate dry filter material of the primary configuration and the advanced dry filter material of the secondary configuration are further overlapped and integrally welded to the front surface of the dust mask body formed as described above. "Limited structure forming means" that minimizes the non-contact part with the entire face due to the flexibility and softness of the material of the face contact part when the dust mask body is worn by welding-bonding configuration;

In contrast to the known technical idea of a single structure, the structural differentiation for realizing the purpose of the present invention is clear, and the "elements of composition" can be affirmed to improve the inventive step of functional effects by the clear structural differentiation as described above. It is a means of solving the problem of "problem to be solved" of the present invention to solve the insignificant problems of conventional products by implementing.

In addition, the high-grade dry filter material, which is the secondary component of the dust mask body, is composed of nano-fibers of synthetic fibers containing carbon (activated carbon) components and is composed of high-grade dry filter material with a multi-layer structure. In the "limited structure forming means" that allows comprehensive filtering,

By impregnating or spraying "colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution" inside the laminated part of the high-quality dry filter material, which is the secondary composition, the high-quality dry filter material becomes the high-quality wet filter material for a certain period of time. As it is a structure formation that does,

On days when the concentration of fine dust is high, fine particles of ultra-fine dust, soot and odors, heavy metals, harmful substances and nitrogen compounds passing through the filtration surface of the primary dry filter material are layered with the high-quality wet filter material as the secondary component. It is a "limited structure forming means" characterized in that the filtration efficiency is further improved comprehensively by adsorbing and absorbing fine water droplets formed by impregnation or spraying into the inside of the laminated portion while passing through the layered portion.

On days when the concentration of fine dust is low, it can be used as the basic filtration function of the intermediate dry filter material, which is the primary component of the dust mask body, and the advanced dry filter material, which is the secondary component. By impregnating or spraying "colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution" into the laminated part of either intermediate or high-quality dry filter material, the filtration function of the dry filter material is the filtration function of the wet filter material. It is a "limited structure forming means" that is converted to a filtration function for a certain period of time to be maintained.

However, as the above situation continues, the "colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution" evaporates inside the laminated part of the wet filter material, and the dry filter material becomes a filtration function state. In a state where the concentration of fine dust is low, It is a "limited structure forming means;" characterized in that it has a humidifying function for the dry air inside the living space while continuing the filtering function of the dry filter material of the dust mask.

(2) As the "limited structure forming means" for the purpose of the present invention, the "composition summary" for the adhesion effect between the dust mask main body and the entire face is described in detail with respect to structural differentiation, which is different from known technical ideas,

Even if the conventional dust mask has an excellent filtration function, a non-contact part may be generated depending on the concave-convex part of the face, so a metal piece is inserted only in the nose part of the face to eliminate the non-contact part by bending the pressure. This structure formation is a non-contact part is formed by weakening the added pressure as the bent part is spread by the tensile force of the left and right rubber bands, and contaminated air is sucked into this non-contact space, which can reduce the efficiency of the filtration function. Bar, the "constitutive gist" of the present invention is "limited structure forming means;" which anticipates and efficiently solves even these problems.

Therefore, looking at the "three-dimensional structure 'collapsible foldable'" dust mask body of the above "limited structure forming means;", the protective support material and the intermediate dry filter material are overlapped to form the first front part and the second rear part. In the formation of the structure of the secondary rear part, the "model (design) shape" designated at the designated position to be composed of "three-dimensional structure 'folding folder type'" at the "designated position". It is a structure forming means in which the lower part penetrates and is pierced with an ultrasonic welder so that it can be easily folded into a three-dimensional folded folder type, and the straight and curved part and the dotted line part are formed as melt-bonded lines in the folded part.

In order to integrally overlap the front part of the primary structure and the rear part of the secondary structure formed as described above, the "mask body" is "three-dimensional structure 'collapsible folder type'" Solid and dotted lines, straight and curved shapes (designs) on the material surface of the flat configuration were formed by ultrasonic welding by "limited structure forming means" so that it could be composed of ".

As described above, certain parts of the upper and lower parts are penetrated, and a certain section is configured so that the top and bottom are melt-bonded in the form of ultrasonic fusion welding lines, so that the filtration surface of the flat dust mask body is "three-dimensional structure folding type 'dust mask body'" It is a "limited structure forming means;" that allows to minimize the non-adhesive portion with the face because the "is made to adhere to the face."

③ In the formation of the structure of the intermediate dry filter material of the secondary configuration identical to the intermediate dry filter material of the primary configuration of the "limited structure forming means" for the purpose of realizing the purpose of the present invention, the structure of the filtering function material is different from the known technical idea. And in detail about the difference,

In the KF80 filtering surface according to known technical ideas, the KF94 standard particles and the KF99 standard particles pass through as finer particles, and about 80% of the KF80 standard particles are controlled, so the filter surface material of the present invention is a synthetic fiber nanoparticle. Since it is formed in a multi-layered structure that can be washed and dried with strong microfibers, if the filter surface of KF94 or KF99 is contaminated, it can be reused after being easily washed and dried in running water. Since the degree of particle size can be controlled, the economic feasibility of such "limited structure forming means" is improved by the filtering function effect of reuse after washing and drying the filtering surface, compared to the uneconomical functional effect of disposable products.

Therefore, the filtering surfaces of the primary and secondary configurations integrally formed on the front and rear portions of the dust mask body of the present invention are formed of an intermediate dry filter material to filter particles (yellow sand or fine dust) of about 10 μm. In this process, if the filter material is contaminated, it can be easily washed and dried in running clean water, so that it can be reused for splash and windproof cold weather, so that economic effects can be realized compared to disposable products. means".

In addition, between the filtering surfaces of the primary and secondary configurations formed of the intermediate dry filter material as described above, three layers of high-quality dry filtering cotton formed separately can be easily inserted between the filtering surfaces of both sides formed of the intermediate dry filter material. Also, the contaminated filtering surface can be easily exchanged, and even in the structure forming means for adhering the mask body to the face, the "elasticity control unit" that can efficiently control the elastic strength of the rubber band of the earring rubber band is provided. It is a "limited structure forming means" in which additional parts are inserted at the bottom of both sides to appropriately adjust the elastic strength.

The dust mask body of the present invention is composed of four layers of front and rear parts by overlapping a multi-layer washable filtration function material formed of nano-fibers of synthetic fibers, and between the front and rear filter surfaces. In the space part formed in the "separately formed high-quality dry filtration cotton can be easily inserted, and the contaminated filtration cotton can be easily exchanged, and the structure forming means for adhering the mask body to the face Also, in the "limited structure forming means", which allows the elastic strength of the earring rubber band to be efficiently adjusted by inserting the "elastic control unit" into the lower portions of both sides of the earring rubber band to properly adjust the elastic strength, yellow sand or fine dust was configured to be filtered on the surface of the intermediate dry filter material (particles of about 10㎛) of the 1st and 2nd configuration, and ultrafine dust, soot, odor and metallic harmful substances were filtered by the 3rd configuration of the high-quality dry filter material ( It has the effect of further improving the efficiency of the filtration function by dispersing it into three dry filter materials so that particles of about 2.5㎛ can be formed.

Filtering function as a wet filter is added by spraying a colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution in the form of impregnation or spraying into the laminated part of any one of the dry filter materials of the primary and secondary structures. It is a "limited structure forming means" that further enhances the effect of the filtering function by adsorbing and absorbing fine water droplets and ultra-fine dust particles contained in the laminated parts of the wet filter.

In addition, the colorless, transparent, odorless, hygienic moisturizing viscous aqueous solution sprayed in the form of impregnation or spray inside the laminated part of the wet filter not only maintains the filtering function as a wet filter for a certain period of time, but also maintains a feeling of refreshment inside the respiratory tract. It has a humidifying function effect in the air.
