Description

Mask structure with nose pad

This invention relates to a structure, in particular a mask structure with a nasal pad.

With the convenience of life brought by industrial development, more and more countries in the world have entered the industrialized society. However, the problems that followed were environmental pollution such as air pollution brought by industrialization, especially the health problems caused by air pollution.

People need to breathe air every day. If there are too many harmful substances in the air, it will cause damage to the human respiratory organs after inhalation. The problem of air pollution poses a threat to human health. According to the "Global Health Risks" report published by the World Health Organization in 2009, urban outdoor air pollution was listed as the 14th risk factor for global deaths in 2004.

Air pollution has many potential health effects, ranging from subtle physiological changes in the body to obvious symptoms such as itchy nose and throat, wheezing, coughing, chest pain or tightness, etc. If patients already have respiratory symptoms, such as asthma or chronic respiratory diseases, their condition will be aggravated when they are exposed to air pollutants.

Although the extent to which people of different ages or physical conditions are affected by air pollution depends on their physical conditions, people of all ages will be affected by poor air quality, and air pollution has a greater impact on the respiratory tract of infants, children and the elderly.

Therefore, in order to avoid inhaling harmful substances in the air (such as PM2.5 suspended particles), viruses, germs, and to prevent droplets or pollen from entering the respiratory organs, many people now wear masks to protect their respiratory organs and avoid inhaling harmful substances when going out or taking public transportation.

Masks are usually worn over the mouth and nose to filter the gases inhaled and exhaled by the human body through the nose, blocking harmful gases from the outside, unpleasant odors, and droplets from others, etc. Masks are mostly made of cloth, non-woven fabrics or paper. If you use a mask made of non-woven fabrics or paper, you should discard it after each use.

However, cotton masks can only block wind, dust, or black smoke from exhaust pipes, and have a warming effect; activated carbon masks can be used to absorb organic gases or odors, but they cannot filter air particles, viruses or bacteria. Activated carbon masks are disposable masks and need to be thrown away after use; non-woven masks (also known as surgical masks) mainly rely on ultra-fine electrostatic fiber cloth and filter layers to filter More than 90% of 5-micron particles (about the size of cells and larger bacteria) are blocked by non-woven masks, but they are disposable masks and need to be thrown away after use. There is also another type of mask that can block the largest number of viruses, germs, droplets, and airborne infections, which is the N95 mask. Although the N95 mask can block harmful substances, it cannot be worn for a long time and is also a disposable mask that needs to be thrown away after use.

However, except for cloth masks, all other masks mentioned above are disposable masks and need to be discarded after use, which will cause a great burden on the environment and will also cause environmental problems when they are handled and discarded. However, reusable cloth masks cannot isolate viruses, germs or other harmful substances.

However, currently disposable or reusable masks have two straps respectively worn on both sides of the mask and a pressure strip set on the upper edge of the mask. When the user wears the mask, the pressure strip is flexible and plastic, and can follow the user's nose and face shape, so that the upper edge of the mask can cover the user's nose and face shape, and there is no gap between the mask and the user's face. The pressure strip used in the current mask is usually an aluminum sheet or other metal sheet. The pressure strip is a rigid material. The pressure strip is in direct contact with the user's face, which is easy to cause pressure marks or other discomfort on the user's face, and the two ends of the pressure strip are sharp, which is easy to scratch the user's facial skin.

Therefore, how to make a mask that can enhance the user's comfort when wearing it, and at the same time, the pad structure has a filtering effect, which can filter the air entering the mask from the outside of the mask to prevent polluted particles in the air from entering the mask, is a problem that technicians in this field want to solve.

In order to help you have a better understanding of the features and effects of this invention, we would like to provide a better implementation example and detailed explanation as follows: The structure of the mask will allow the user to wear the mask. Due to the flexibility and plasticity of the pressure strip, the upper edge of the mask can wrap around the user's nose and face shape, making the mouth The mask can fit tightly against the user's face without any gaps. The pressure strips currently used in masks are usually made of aluminum or other metal sheets. The pressure strips are made of rigid materials and are in direct contact with the user's face, which can easily cause pressure marks or other discomfort on the user's face. In addition, the two ends of the pressure strips are sharp, which can easily scratch the user's facial skin.

In view of the above-mentioned known problems, this invention provides a mask structure with a nasal pad to improve the known problems. This invention sets a soft pad on the inner side of the mask. Through the elastic characteristics of the soft pad, the wearer's nose bridge will not be fixed to the nose bridge for a long time due to wearing the mask for a long time, causing discomfort.

In the following, the invention will be described in detail by illustrating various embodiments of the invention with diagrams. However, the concept of the invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments described herein.

First, please refer to Figure 1A, which is a schematic diagram of a mask structure with a nose pad in one embodiment of the present invention. As shown in the figure, the mask structure with a nose pad in this embodiment includes a mask body 10 and a soft pad 20.

Further referring to FIG. 1B, it is a three-dimensional schematic diagram of a mask structure with a nose pad according to an embodiment of the present invention. In this embodiment, the mask body 10 further comprises a first protective layer 12, a first filter layer 14 and a skin-friendly layer 16. The first protective layer 12, the first filter layer 14 and the skin-friendly layer 16 are arranged in sequence from the outside to the inside. A pressure strip 11 is arranged at the mouth. One side of the mask body 10, and a containing space 18 is provided in the skin-friendly layer 16, and the containing space 18 is used to buffer a gas inhaled by the user from an external environment. Specifically, the pressure strip 11 can be arranged on the upper side of the mask body 10, that is, the nose bridge side, or on the lower side of the mask body 10, that is, the chin side. This embodiment uses the nose bridge side as an example, but is not limited thereto.

Please refer to FIG. 1C, which is an enlarged structural diagram of the nose bridge groove of the mask structure with a nose pad in one embodiment of the present invention, and FIG. 1D, which is an enlarged structural diagram of the mask structure with a nose pad in one embodiment of the present invention. As shown in the figure, in this embodiment, the soft pad 20 is arranged on an inner side 13 of the mask body 10 and covers the pressure strip 11. The soft pad 20 includes a body 21 and a covering member 28. The body 21 is provided with a plurality of through holes 211. The body 21 has a first side 201 and a second side 203, which are the lower side and the upper side of the body 21, that is, the first side 201 and the second side 203. The side 203 is relatively disposed on the covering member 28. A third side 22 and a fourth side 24 are respectively disposed on the two sides of the body 21. The third side 22 and the fourth side 24 of the present embodiment are respectively the left side and the right side of the covering member 28. That is, the third side 22 and the fourth side 24 of the present embodiment are relatively disposed on the covering member 28. On the covering member 28, the third side 22 and the fourth side 24 of this embodiment are adjacent to the first side 201 and the second side 203 respectively, so at least one edge angle formed by the third side 22 and the fourth side 24 corresponding to the first side 201 and the second side 203 is an example of a beveled edge as a non-sharp edge.

Among them, in this embodiment, a nose bridge groove 207 is further provided on the main body 21 of the third side 22 and the fourth side 24, and the covering member 28 covers the main body 21, the third side 22, the fourth side 24 and the nose bridge groove 207. The main body 21 is a foam body or a fluffy fiber body. In this embodiment, the diagram shown in Figure 1D, wherein the nose bridge groove 207 in the diagram of this embodiment should also be covered by the second filter layer 23. Only to make the diagram clear and easy to read, the diagram of the nose bridge groove 207 is omitted in the diagram.

The soft pad 20 of this embodiment is disposed on the mask body 10 with the first side 201 as the lower side, and is connected to one side of the pressure strip 11 with one inner side 13 of the mask body 10, while the other side of the soft pad 20 is not connected to the inner side 13 of the mask body 10. That is, the soft pad 20 of this embodiment is disposed on the mask body 10 with the first side 201 as the lower side, and is connected to one side of the pressure strip 11 with one inner side 13 of the mask body 10. The second side 203 is not disposed on the mask body 10 as an upper side, but is disposed separately from the mask body 10. In this way, the covering member 28 does not fix the shape of the main body 21, and the main body 21 can be extended in the covering member 28, so that the soft pad 20 has good fluffiness and can change the external shape at will with external force.

Please refer to Figure 2A, which is a schematic diagram of the use state of one embodiment of the present invention, and Figure 2B, which is an enlarged schematic diagram of the use state of one embodiment of the present invention. As shown in the figure, in this embodiment, a gas flows in (at the dotted arrow in the figure) or flows out (at the dotted arrow in the figure) through the mask body 10 and the soft pad 20.

The advantage of this embodiment is that the soft pad 20 is arranged on the inner side of the mask body 10. The elastic properties of the soft pad 20 prevent the wearer's nose bridge from being fixed by the pressure strip 11 for a long time due to wearing the mask for a long time, which causes discomfort. The non-sharp edges are arranged on both sides of the upper part of the soft pad 20, that is, the The third side 22 and the fourth side 24 respectively form a non-sharp edge shape trimming feature with the second side 203, which increases the comfort when wearing and prevents the soft pad 20 from causing discomfort to the user. The third side 22 and the fourth side 24 of this embodiment are beveled edges, that is, the original right-angled edges are trimmed into blunt edges to achieve the purpose of shape trimming.

Here is an implementation example:

When a user 90 wears the mask structure with a nose pad of the present embodiment, the soft pad 20 is located between the mask body 10 and the user 90, and fills the gap between the nose bridge of the user 90 and the mask body 10, and the soft pad 20 directly contacts the nose of the user 90 and the cheeks on both sides of the nose. , and although the pressure strip 11 is usually made of aluminum sheet or other metal sheet or plastic-coated metal strip or plastic-coated metal sheet, due to the setting of the soft pad 20 in this invention, the pressure strip 11 will not directly contact the nose and cheek of the user 90, that is, when the mask structure is worn, the second side 203 of the soft pad 20, that is, the upper side, is folded to the top of the pressure strip 11.

Because the pressure strip 11 is easy to bend due to the above-mentioned aluminum sheet or thin metal sheet, the pressure strip 11 can be shaped according to the shape of the nose and cheeks of the user 90, so that the soft pad 20 located outside the pressure strip of the mask body 10 fits tightly with the nose and cheeks of the user 90.

Furthermore, the nose bridge groove 207 provided at the place where the soft pad 20 fits the nose of the user 90 can cooperate with the soft pad 20 to fit the nose of the user 90 extremely well without causing discomfort. The soft pad 20 is made of soft material and has good fluffiness, which will not make the user 90 feel uncomfortable when wearing the mask body 10, for example: avoiding the pressure strip 11 from pressing or rubbing the user's nose.

In addition, in this embodiment, the two sides of the soft pad 20 further include a first surface 25 and a second surface 27. The first surface 25 is disposed on one side of the soft pad 20 opposite to the pressure strip 11, and the second surface 27 is disposed on the inner side of the soft pad 20 opposite to the mask body 10. The curvature of the first surface 25 is equal to the curvature of the second surface 27, which is a relatively symmetrical state (as shown in Figure 1D).

The curvature of the first surface 25 and the second surface 27 can also be asymmetrical. Please refer to Figure 3, which is another schematic diagram of the use state of one embodiment of the present invention. As shown in the figure, the curvature of the second surface 27 of the soft pad 20 is greater than the curvature of the first surface 25, wherein the curvature of the first surface 25 of the soft pad 20 is close to a plane. Therefore, as shown in Figure 3, the cross-sectional shape of the soft pad 20 is D-shaped. In this embodiment, the diagram shown in Figure 3 shows that the nose bridge groove 207 is also covered by the covering member 28. In order to make the diagram clear and easy to read, the diagram of the nose bridge groove 207 is omitted in the diagram.

That is, when the user 90 wears the mask structure of the present embodiment, the second surface 27 of the soft pad 20 contacts and fits the face of the user 90, and the first surface 25 of the soft pad 20 is close to the inner surface 13 of the mask body 10. In this way, the other side of the soft pad 20 that is not fixed to the inner surface 13 of the mask body 10 is less likely to rise, so as to avoid contact with the face of the user 90 and friction.

Next, please refer to Figure 4A, which is a schematic diagram of the structure of a soft pad of an embodiment of the present invention. As shown in the figure, the soft pad 20 of the present embodiment further includes a second filter layer 23 and a sterilization layer 26. The sterilization layer 26 is arranged between the main body 21 and the second filter layer 23, which means that the second filter layer 23 and the sterilization layer 26 are arranged between the covering 28 and the main body 21. The sterilization layer 26 covers the outer layer of the main body 21, and the second filter layer 23 covers the main body 21 having the sterilization layer 26. In addition, any edge angle of the third side 22 and the fourth side 24 of the present embodiment is chamfered as an example of a non-sharp edge. The third side 22 and the fourth side 24 of the soft pad 20 further respectively set a first edge angle 222 and a second edge angle 224, and a third edge angle 242 and a fourth edge angle 244. Corner 244, wherein the second edge corner 224 and the fourth edge corner 244 are respectively arranged on the lower sides of the soft pad 20, that is, on the sides of the first side 201, and the first edge corner 222 and the third edge corner 242 are respectively arranged on the upper sides of the soft pad 20, that is, on the sides of the second side 203. The first edge corner 222, the second edge corner 224, a third edge corner 242 and a fourth edge corner 244 of this embodiment are arc-shaped edge corners, so as to further use the arc to replace the right angle of the edge, and achieve the purpose of shape trimming, thereby avoiding discomfort when wearing, for example: avoiding sharp edges from poking or pricking the face on both sides of the nose of the user.

Since the soft pad 20 has the second filter layer 23 (refer to Figure 2A and Figure 2B again), when the user 90 breathes, the second filter layer 23 can filter the gas entering the space 18 of the mask body 10 from the outside of the mask body 10 (refer to the dotted arrows in Figure 2A and Figure 2B again), so as to filter the polluting particles such as dust and powder in the gas, thereby preventing the polluting particles in the gas from entering the mask body 10 from the soft pad 20, and preventing the user from inhaling the polluting particles in the gas.

On the contrary, the gas with droplets exhaled by the user 90 can also be filtered (refer to the dotted arrows in Figure 2A and Figure 2B), so that the gas exhaled by the user 90 can be filtered through the second filter layer 23 to prevent the droplets exhaled by the user 90 from being transmitted to the external environment.

Finally, the second filter layer 23 is covered by the covering member 28, which protects the second filter layer 23, the sterilizing layer 26 and the main body 21 in the soft pad 20 and prevents the second filter layer 23, the sterilizing layer 26 and the main body 21 from being contaminated by dirt.

When the soft pad 20 of this embodiment is disposed on the mask body 10, when the user 90 wears the mask body 10, the soft pad 20 makes the mask body 10 fit the face of the user 90 and can improve the comfort of the user 90 wearing the mask body 10.

The gas located in the mask body 10 enters the mask body 10, the second filter layer 23 of the soft pad 20 filters the pollutant particles in the gas, and the sterilization layer 26 eliminates the bacteria or viruses in the gas to prevent the pollutant particles, bacteria or viruses in the gas from entering the mask body 10, thereby preventing the user 90 from inhaling pollutant particles or being infected with bacteria or viruses.

Further, please refer to FIG. 4B, which is a schematic diagram of the structure of a soft pad of an embodiment of the present invention, and FIG. 4C, which is a schematic diagram of the structure of a soft pad of an embodiment of the present invention. As shown in the figure, the sterilization layer 26 of the present embodiment can be replaced by an electrostatic layer 29 (as shown in FIG. 4B), or the electrostatic layer 29 can be added between the sterilization layer 26 and the body 21 (as shown in FIG. 4C). , the electrostatic layer 29 can adsorb bacteria or viruses that have not been eliminated by the sterilization layer 26, that is, in this embodiment, as shown in Figure 4B, the second filter layer 23 and the electrostatic layer 29 are arranged between the covering 28 and the main body 21, or, as shown in Figure 4C, the second filter layer 23, the sterilization layer 26 and the electrostatic layer 29 are arranged between the covering 28 and the main body 21.

In the embodiments disclosed in Figures 4A to 4C above, the third side 22 and the fourth side 24 are sealed by ultrasonic pressing or heat pressing, so that the combination of the second filter layer 23, the sterilizing layer 26, and the electrostatic layer 29 covers the body 21. In addition, in the embodiments shown in Figures 4D to 4F, the body 21 can be extended to the openings of the third side 22 and the fourth side 24, that is, as shown in the schematic diagram disclosed in the side view shown in Figure 1A, although the body 21 is covered by the combination of the second filter layer 23, the sterilizing layer 26, and the electrostatic layer 29, the body 21 can still be seen from the side.

Further referring to Figures 5 to 7, they are enlarged schematic diagrams of other embodiments of the soft pad 20 of the present invention disposed on the mask body 10. As shown in Figure 5, the difference between it and Figure 1D is that the first side 201 of the bottom of the soft pad 20 in Figure 1D is connected to the interface mask body 10, and a second side 203 of the upper part of the soft pad 20 in Figure 5 is connected to the skin-friendly layer 16 of the interface mask body 10. As shown in Figure 6, the difference between it and Figure 5 is that Figure 5 shows the upper part of the soft pad 20 connected to the skin-friendly layer 16 of the interface mask body 10, and Figure 6 shows the middle part of the soft pad 20 connected to the interface mask body 10, especially the middle part of the first surface 25 connected to the skin-friendly layer 16 of the interface mask body 10.
