By the way, masks generally refer to appliances worn on the mouth and nose. Their main purpose is to filter the air in and out of the nose to prevent bacteria, dust, or droplets from entering and leaving the wearer's body. The current masks are mostly made of cloth or paper. Most of them are disposable products.

There are many types of masks, such as: cotton masks, paper masks, medical masks, activated carbon masks, dust (haze) masks, flat masks and three-dimensional masks... When users usually clean the environment, they are suitable for wearing dust masks. When the user has respiratory symptoms such as cold, fever, or cough, or goes to hospitals, movie theaters and other unventilated places, it is suitable to wear medical masks. With many types of masks, users can be used in different occasions. In the middle, wear a mask suitable for this occasion to filter bacteria and dust in the air, reduce the spread of diseases, and at the same time protect your own health.

As mentioned above, there are endless types of masks on the market. Among them, there are anti-fog masks that combine a plastic sheet on the upper side of the mask. The main purpose is to use the plastic sheet to prevent the breath from the mouth from spreading to the lens, so as to avoid the lens from getting off. A foggy situation occurs.

However, when the above-mentioned anti-fog masks with plastic sheets are used, there are the following problems and deficiencies that need to be improved:

First, the plastic sheet is attached to the wing of the nose, which is easy to make users feel uncomfortable.

Second, due to the material of the plastic itself, although it can effectively block the air from escaping to the lens, it can easily lead to problems such as inability to circulate air and breathing difficulties.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the applicant of the present invention and related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of the present invention has collected relevant information, evaluated and considered by multiple parties, and has accumulated years of experience in this industry, through continuous trials and modifications, to design such an effective anti-fog, and Patented for the invention of the structure of an anti-fog mask that allows users to feel comfortable and breathe smoothly.

The main purpose of the present invention is: through the structure and material of the first blocking member and the second blocking member, the present case can effectively prevent fogging while improving the comfort of wearing, and avoid the occurrence of unsatisfactory breathing.

Another main purpose of the present invention is to accumulate and absorb the exhaled gas through the first electrostatic layer and the second electrostatic layer, so as to greatly reduce the speed of the gas passing through the mask body, achieve the double-layer filtering effect, and maintain good air permeability at the same time Sex and capture.

To achieve the above objective, the main structure of the present invention includes: a mask body, the mask body includes a first air-permeable layer, one side of the first air-permeable layer is connected with a first electrostatic layer, the first electrostatic layer is away from one of the first air-permeable layers A second electrostatic layer is connected to the side, a second breathable layer is connected to the side of the second electrostatic layer away from the first electrostatic layer, and the mask body is combined with a first blocking member and a second blocking member, and the second blocking member is located at The first blocking member is away from one side of the first air-permeable layer, and the first blocking member and the second blocking member are both made of cloth material. In addition, a plurality of hanging members are arranged on both sides of the mask body.

Through the above-mentioned structure, when a user wearing glasses hangs the mask body on the face with a hanger, during the user’s breathing, the exhaled gas will evaporate upward and forward respectively, and the evaporating gas will follow After passing through the first gas-permeable layer, the first electrostatic layer, the second electrostatic layer, and the second gas-permeable layer in sequence, the structure of the first electrostatic layer and the second electrostatic layer will reduce the diffusion speed of the gas, and at the same time, the gas Accumulation and absorption, so the gas will flow out of the cover body at a slow speed, which can prevent the lens from contacting a large amount of gas at one time, causing the glasses to fog.

In addition, the upwardly floating gas cannot be directly dispersed from the upper gap to the lens due to the design of the first blocking member and the second blocking member, so as to achieve an effective anti-fog effect. In addition, the first blocking member and the second blocking member are both made of cloth and attached to the nose of the user, which will not make the user feel uncomfortable, nor will the user feel the problem of unsatisfactory breathing.

With the above-mentioned technology, it is possible to overcome the problems of low comfort and unsatisfactory breathing of the anti-fog mask of the conventional plastic sheet, so as to achieve the practical progress of the above-mentioned advantages.

In order to achieve the above-mentioned purposes and effects, the technical means and structure adopted by the present invention are illustrated below in detail to illustrate the characteristics and functions of the preferred embodiments of the present invention, so as to fully understand.

Please refer to the first and second figures, which are the three-dimensional perspective view and the exploded view of the preferred embodiment of the present invention. It can be clearly seen from the figures that the present invention includes: a mask body 1 including a mask body 1 The first air-permeable layer 11, a first electrostatic layer 12 connected to the side of the first air-permeable layer 11, a second electrostatic layer 13 connected to the side of the first electrostatic layer 12 away from the first air-permeable layer 11, and A second air-permeable layer 14 connected to the side of the second electrostatic layer 13 away from the first electrostatic layer 12; a first blocking member 2, one side of the first blocking member 2 is bonded to the first air-permeable layer 11 , And the first blocking member 2 is made of cloth material; a second blocking member 3, one side of the second blocking member 3 is coupled to the first air-permeable layer 11, and is located on the first blocking member 2 away from the first One side of the air-permeable layer 11, and the second blocking member 3 is made of cloth material; and a plurality of hanging members 4, each of the hanging members 4 is arranged on both sides of the mask body 1.

Preferably, both sides and upper side of the first blocking member 2 are thermally press-bonded to the mask body 1.

Preferably, both sides and upper side of the second blocking member 3 are thermally and press-bonded to the mask body 1.

Preferably, the first breathable layer 11 is the inner fabric that contacts the face and mouth when the mask body 1 is worn, the second breathable layer 14 is the outer fabric, the first electrostatic layer 12 and the second electrostatic layer 13 The density and fiber diameter are different. In addition, the number of the hanging member 4 is two and it has elasticity, so as to be used as the ear rope of the mask body 1.

Through the above description, we can understand the structure of this technology, and according to the corresponding cooperation of this structure, it can effectively prevent fogging, and make the user feel comfortable and breathable when wearing. The detailed explanation will be as follows instruction.

Please also refer to Figures 1 to 4 at the same time, which are the three-dimensional perspective view to the stacked schematic view of the preferred embodiment of the present invention. When the above-mentioned components are assembled, it can be clearly seen from the figure that when the user If you want to wear the mask body 1 and glasses at the same time, you need to hang the hanger 4 on both ears to complete wearing the mask body 1, and then put on the glasses. During wearing, if the user breathes out, exhale The gas 5 of will diffuse in all directions, and the most likely cause of the fogging of the glasses is the gas 5 that drifts upward and the gas 5 that drifts forward.

The gas 5 that diffuses forward passes through the first air-permeable layer 11, the first electrostatic layer 12, the second electrostatic layer 13, and the second air-permeable layer 14 of the mask body 1 in sequence, and then exits the outer side of the mask body 1. When the gas 5 passes through the first gas-permeable layer 11, the first gas-permeable layer 11 will start to absorb the moisture in the gas 5, thereby preventing the moisture from passing through the first gas-permeable layer 11, and when part of the gas 5 floats through the first gas-permeable layer 11, it contacts When the first electrostatic layer 12 is connected to the first air-permeable layer 11, the first electrostatic layer 12 will filter the dust and bacteria in the gas 5 through its electrostatic charge structure, thereby blocking the dust and bacteria.

At this time, the filtered gas 5 will pass through the first electrostatic layer 12 and contact the second electrostatic layer 13 connected to the side of the first electrostatic layer 12, and pass through the electrostatic charge structure of the second electrostatic layer 13 to filter dust and dust again. Bacteria and achieve the effect of slowing down the diffusion speed of the gas 5 and accumulating the gas 5. Finally, the gas 5 resisted by the second electrostatic layer 13 will pass through the second electrostatic layer 13 at a slow diffusion speed and contact the Although the main function of the second breathable layer 14 of the second electrostatic layer 13 is to prevent flying and prevent dust and bacteria in the air from entering the human respiratory system, the second breathable layer 14 can also assist the second electrostatic layer 13. It has a mitigating effect on gas 5, so gas 5 will be After being relieved once, and passing through the second air-permeable layer 14, it can escape out of the cover body 1.

The spectacles are fogged because the temperature of the spectacles is lower than that of the exhaled gas 5. When the exhaled gas 5 contacts the lens on the glasses, it will condense into small water droplets and adhere to the lens, causing the problem of fogging. , But the dissipating speed of the mist is also very fast, which means that if a large amount of gas 5 comes into contact with the lens at one time, it will cause fogging, and if the gas 5 diffuses slowly and continuously, the fog generation will be reduced. Speed, so that there will be no fogging and other conditions.

Therefore, after the gas 5 exhaled from the mouth passes through the accumulation and absorption of the first electrostatic layer 12 and the second electrostatic layer 13, it will float out of the mask body 1 at a slow diffusion speed, thereby avoiding a large amount of contact with the lens at one time The gas 5 prevents the gas 5 from condensing into small water droplets and generating mist on the lens.

The above belongs to the blocking process of the forward floating gas 5, however, when the user exhales, the upward floating gas 5 will not be dispersed in large quantities at one time due to the design of the first blocking member 2 and the second blocking member 3. On the lens, it can be clearly seen from the fourth figure that the first blocking member 2 and the second blocking member 3 will be separated from each other during use for the user’s nose to be attached. Therefore, the exhaled air 5 will accumulate in Between the first blocking member 2 and the second blocking member 3, and because the second blocking member 3 is attached to the wing of the nose, there is no gap at the top of the mask body 1, so the gas 5 cannot easily diffuse from above. On the lens.

Moreover, the gas 5 remaining in the first blocking member 2 and the second blocking member 3 cannot be dispersed from above, and the gas 5 that is dispersed forward passes through the first gas-permeable layer 11, the first electrostatic layer 12, and the first gas layer in order. The two electrostatic layers 13 and the second air-permeable layer 14 are accumulated and absorbed as described above. In addition, the first blocking member 2 and the second blocking member 3 in this case are limited to using fabric materials, that is, in order to overcome the shortcomings of conventional plastic sheets, the first blocking member 2 and the second blocking member 3 made of fabric materials can be improved It is comfortable to wear, and there is no problem of breathing difficulties. Because the cloth itself still has small fiber holes, it can make the breathing process of the user smooth, and it is especially important that it passes through the first blocking member 2 , The second blocking member 3, the first electrostatic layer 12, and the second electrostatic layer 13 are used to achieve the purpose of multi-layer blocking, thereby avoiding fogging of the glasses.

According to the data, medical masks must have a bacterial filtration efficiency of more than 95% and a pressure difference (respiratory impedance) of less than 5mmH ₂ O/cm ² in order to meet the national standards for medical masks, and use the first static electricity The structure of layer 12 and the second electrostatic layer 13 with different densities and fiber diameters can meet the above two conditions at the same time, and then achieve an appropriate balance point between the bacterial filtration efficiency and the pressure difference, so that the present invention can not only effectively filter the air The dust and bacteria in it can also maintain good ventilation effect.

Please also refer to Figures 5 to 9 at the same time, which are a three-dimensional perspective view to a release schematic view of another preferred embodiment of the present invention. When the above-mentioned components are assembled, it can be clearly seen from the figure that the present invention The embodiment is similar to the above-mentioned embodiment. In this embodiment, the mask body 1a is provided with a plurality of joints 15a on both sides, and the two ends of the hanger 4a are connected to the joints 15a, and the mask body 1a has a certain type piece 16a. , And the shaped piece 16a is adjacent to the first blocking member 2a and the second blocking member 3a. In addition, the first blocking member 2a is formed with a first front end 21a and a first rear end 22a, so that the first blocking member 2a is formed A first space 23a, a second blocking member 3a are formed with a second front end 31a and a second rear end 32a, so that a second space 33a is formed in the second blocking member 3a, and the first air-permeable layer 11a and the first A first accommodating space 17a is defined between the electrostatic layers 12a, a second accommodating space 18a is defined between the first electrostatic layer 12a and the second electrostatic layer 13a, and a second accommodating space 18a is defined between the second electrostatic layer 13a and the second gas-permeable layer 14a. A third accommodating space 19a is defined.

Preferably, the first blocking member 2a and the second blocking member 3a are bent to form a U shape.

The connecting portion 15a takes a thin layer of cloth as an example, and its number is two and is located on the left and right sides of the mask body 1a. The connecting portion 15a is used to fix the hanging member 4a, so that the hanging member 4a can be firmly connected to the mask body 1a, thereby preventing the hanging member 4a from falling off easily.

The shaping piece 16a is a flexible nose bridge strip. The shaping piece 16a of this embodiment is set at a position corresponding to the bridge of the nose, so that the user can make the mask body 1a fit closely to the user through the shaping piece 16a On the nose wing, to reduce the possibility of bacteria floating from the upper side of the mask body 1a, so as to prevent air contact with the lens and generate fog, thereby enhancing the overall anti-fogging effect.

Through the design of the first front end 21a and the first rear end 22a of the first blocking member 2a, the first blocking member 2a can be bent to form a U shape and create a first space 23a. In this way, when the gas 5a passes through the first During the process of the blocking member 2a, it is first blocked by the first space 23a and temporarily stored in the first space 23a. At this time, the first space 23a can play the function of accumulating and reducing the diffusion rate of the gas 5a, thereby improving the overall anti-fog Effect. In the same way, the second front end 31a, the second rear end 32a, and the second space 33a of the second blocking member 3a can also achieve this effect.

The design of the first accommodating space 17a, the second accommodating space 18a, and the third accommodating space 19a, when the user exhales the air 5a, it will pass through the first gas-permeable layer 11a, the first accommodating space 17a in sequence , The first electrostatic layer 12a, the second accommodating space 18a, the second electrostatic layer 13a, the third accommodating space 19a, and the second air-permeable layer 14a, after the first electrostatic layer 12a filters the gas 5a, you can Dust and bacteria are blocked in the first accommodating space 17a. After the second electrostatic layer 13a filters the gas 5a and slows down the diffusion speed of the gas 5a, the gas 5a can also be accumulated and stored in the second accommodating space 18a. In addition, the third accommodating space 19a can also achieve the effect of auxiliary storage. Therefore, through the structure of the first accommodating space 17a, the second accommodating space 18a, and the third accommodating space 19a, it is possible to increase the gas 5a through the mask The time required for the main body 1a.

In addition, the basis weights of the first electrostatic layer 12a and the second electrostatic layer 13a are between 10g/m ² and 30g/m ^2. This embodiment takes 15g/m ² as an example. Such a configuration can be used to filter dust and bacteria. , And accumulate the gas 5a at the same time, improve the overall air permeability, so that the user will not have breathing difficulties due to the structure of the first electrostatic layer 12a, the second electrostatic layer 13a, or the second accommodating space 18a, although The accumulation of the gas 5a in the second accommodating space 18a does not mean that the gas 5a cannot pass through the second electrostatic layer 13a and is released. The first electrostatic layer 12a and the second electrostatic layer 13a only allow the gas 5a to be stored in In the second accommodating space 18a, and using its structure to slowly and continuously release the gas 5a in the second accommodating space 18a, therefore, when the basis weights of the first electrostatic layer 12a and the second electrostatic layer 13a meet the above range, it is sufficient While maintaining the overall breathability and trapping properties, it avoids fogging. It can achieve a balance between the efficiency of the accumulated gas 5a and the air permeability level, so that the speed of the gas 5a exiting the mask body 1a is reduced to the point that no mist can be generated on the lens. At the same time, the user can maintain good air permeability when breathing.

In addition, the basis weight of the first air permeable layer 11a is between 17g/m ² ~ 30g/m ^2. This embodiment takes 20g/m ² as an example. Such a configuration has the effect of low density and low pressure difference, which can be effective It absorbs the moisture generated when the user breathes or speaks, so the first air-permeable layer 11a has good air permeability, thereby assisting the first electrostatic layer 12a and the second electrostatic layer 13a to improve the overall air-permeability effect.

In addition, the basis weight of the second air permeable layer 14a is between 15g/m ² ~50g/m ² , 30g/m ^{2 is taken} as an example in this embodiment. Such a configuration has good flying barrier properties and can effectively prevent The splashed water vapor also assists the first electrostatic layer 12a and the second electrostatic layer 13a to slow down the flow rate of the gas 5a. When the gas 5a located in the second containing space 18a passes through the second electrostatic layer 13a, it moves to the third container. When placing the space 19a and want to pass through the second air-permeable layer 14a, due to the structure of the second air-permeable layer 14a, its dispersion speed will be reduced again, thereby reducing the chance of fog generation on the lens.

In addition, the first electrostatic layer 12a and the second electrostatic layer 13a of this embodiment are melt-blown non-woven fabrics. The melt-blown non-woven fabrics spray the molten polymer from the spinning nozzle, and the heated air and the cooling air flow are matched with each other to spray out the molten polymer. The polymer is cut into fibers, and finally the non-woven fabric is made by the method of collecting on the screen surface. Because of its small fiber diameter, melt-blown non-woven fabric has the characteristics of large surface area, small voids, and high porosity. Through its material characteristics, it has good filterability and shielding performance. Therefore, when melt-blown non-woven fabric is used as a filter When applying electrostatic charge treatment, it can effectively improve the filtering effect of meltblown non-woven fabric. In this way, not only can the dust and bacteria generated in the air be accurately filtered, but also through its shielding property, the gas 5a can be accumulated in the second accommodating space 18a. Therefore, the first electrostatic layer 12a and the second electrostatic layer 13a is the design of meltblown non-woven fabric, which can strengthen the overall bacteria filtering effect, and also enhance the efficiency of gas 5a accumulation, thereby avoiding the generation of fog on the lens.

However, the above description is only the preferred embodiments of the present invention, which does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention should be the same. It is included in the scope of the patent of the present invention, and is hereby stated.
