Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings.

With reference to Figures 1 and 2, in an illustrated embodiment, the present invention provides a mask 10, including a mask body 101, which is provided with a mask body for cooperating with the wearer's head to fix the mask body As a preferred method, the elastic connecting portion 102 can be a rubber band with a cloth wrapping layer, and the mask body 101 is provided with a color changing portion 103 made of a temperature-sensitive color changing material; In an optional embodiment, as long as the discoloration part has at least a part exposed, or the discoloration part is covered with a light-transmitting layer, for example, a transparent covering layer is provided, the discoloration caused by the human skin temperature can be caused by the discoloration part. It is displayed and observed, so as to achieve an objective of the present invention. It should be noted that the color change caused by the color change portion 103 may include the following situations, for example, when the temperature changes, it changes from one color to another, or gradually changes from one color to transparent, or, at the initial stage There are many different color conversions from color to final color. In the following exemplary embodiments, the present invention only provides limited examples for description, but should not be regarded as a limitation of the present invention.

In order to implement the discoloration part on the mask body, in one embodiment, as shown in FIG. 1, a first hot pressing area 104 is provided on the mask body in the area where the elastic connecting part is not located. It needs to be explained Yes, the first hot pressing area is an area selected on the mask body according to requirements, and is used to make the discoloration part in the subsequent manufacturing process. After hot pressing, the thickness of the mask in this area will become thinner. The multi-layer fluffy structure becomes compact under the action of hot pressing; the first hot pressing area 104 is formed with a temperature-sensitive base layer 105 by hot pressing, and the temperature-sensitive base layer 105 is printed on the side away from the human facial skin There are color-changing inks. As a preferred embodiment, the temperature-sensitive basal layer is located on the mask body corresponding to the position of the cheekbones or a position close to the cheekbones. In this way, when the mask is worn, due to the structural characteristics of the human cheekbones and the tension of the elastic connecting portion 102, sufficient pressure can be applied to the temperature-sensitive base layer 105 to ensure sufficient contact between the skin and the temperature-sensitive base layer to prevent The heat on the skin surface is dissipated to ensure the accuracy of the temperature sensed by the thermochromic material as much as possible. Of course, for the position selection of the temperature-sensitive base layer 105, the above is only the best embodiment. If the temperature-sensitive base layer is set in other positions, the temperature of the skin can also be sensed, but in this case, the temperature of the skin can be sensed. The temperature error is relatively large.

In the present invention, when the above structure is adopted, the color changing part can also be made by the following process. The mask body in the area where the elastic connecting part is not located is provided with a temperature-sensitive color changing mark made of color changing ink by means of silk printing. , The process of making masks with discoloration parts through the silk screen process is simple and the production efficiency is high. In one embodiment, the specific operation is to formulate a grid plate with preset pattern marks, mix thermochromic color powder and non-temperature change color powder into liquid silica gel to make silicone ink, and then print the preset pattern marks through a silk screen process On the mask body. During silk-screen printing, the multi-layer fluffy structure of the temperature-sensitive base layer becomes compact under the action of hot pressing. Compared with other areas that are not screen-printed, the temperature-sensitive base layer becomes a relatively thin and dense part, which is beneficial to heat conduction in a short time. The temperature of the human facial skin can be sensed inside.

In the present invention, the color-changing ink is made of titanium dioxide, thermochromic powder, non-thermochromic powder, and liquid silica gel. The specific process is to add titanium dioxide, thermochromic powder, and non-thermochromic powder to the liquid at room temperature. Stir evenly in the silica gel. In the screen printing process, the color-changing ink is sprayed onto the material through the screen printing equipment, and is formed by thermal curing or ultraviolet curing. Or use other printing equipment to make the ink on the temperature-sensitive base layer, such as the aforementioned hot pressing method.

In a preferred embodiment, the color-changing ink can be jet-printed as a preset letter, number, text or pattern, or a combination thereof. For example, in Figure 1, the word "H" is printed with a color-changing ink, which can act as a warning when the color of the word "H" changes. Of course, it can also be printed as a brand LOGO, etc., which is not limited here.

In the present invention, as an optional embodiment, the color-changing ink includes toner and liquid silica gel, wherein the ratio (mass percentage) of the toner to the liquid silica gel is as follows, titanium dioxide (DuPont R-105): 0.04% -1%, Insilicoyellow31E: 0.08%-1%, InsilicoRoyalBlue31E: 0.32%-1%, Peach pink (Dun FL503, Korea): 0.2%-1% , Liquid silica gel (DuPont liquid silica gel, etc. RBL-9200-30): 95.7%-99.24%. The base color of the color-changing ink obtained by this ratio is purple. Starting at 35°C, as the temperature increases, the color of the color-changing ink starts to change from purple. The specific color change process is purple-light purple-light peach-dark peach. When the skin temperature sensed by the color-changing ink exceeds 37 degrees, its color is embodied as a deep peach. The ink can be sprayed out regardless of hot pressing or silk screen printing.

In the present invention, the discoloration part can also be provided on the mask body by another manufacturing process. The specific operation is that a through hole is provided on the mask body in an area other than the elastic connecting part, and the discoloration part is provided on the mask body. The part is a flexible resin sheet in which thermochromic powder is mixed; the flexible resin sheet blocks the through holes. As a preferred manner, the through hole is located on the mask body corresponding to the position of the cheekbones or a position close to the cheekbones.

In this embodiment, a punching machine or manual cutting method is used to open a hole in the manufactured mask; at 170°C-200°C, an injection molding machine is used to inject the TPE and TPU materials mixed with thermochromic powder According to the preset mold, the temperature-sensitive and color-changing mark is obtained; the obtained temperature-sensitive and color-changing mark is welded on the mask body by ultrasonic welding, so that a flexible resin sheet that can sense the temperature of the facial skin is formed on the mask body. Among them, in an alternative embodiment, the resin made of TPE or TPU can be made of Formosa Plastics polypropylene PP5090T, Maoming Petrochemical LDPE2420K, ExxonMobil LLDPE6101, GLSTPEC3620 material, and LubrizolTPU58125. The ratio of toner to resin (mass percentage) is as follows, titanium dioxide (DuPont R-105): 0.04%-1%, temperature-changing golden yellow powder (Insilicoyellow31E): 0.08%-1%, temperature-changing Baolan toner ( InsilicoRoyalBlue31E): 0.32%-1%, pink powder (Korea Dawn FL503): 0.2%-1%, dispersant (ClariantPEWax3620): 0.12%-0.3%, resin: 95.7%-99.24%. The base color of the flexible resin sheet obtained by this ratio is purple. Starting at 35°C, the color of the flexible resin sheet changes from purple as the temperature increases. The specific color change process is: purple-light purple-light pink-dark peach Red, when the skin temperature sensed by the flexible resin sheet exceeds 37 degrees, its color will be deep pink.

The color change principle of the present invention is that the temperature change color powder becomes transparent after reaching a preset temperature, so that the color of the non-temperature change color powder can be reflected. For example, in the aforementioned ratio, the temperature change golden yellow powder (Insilicoyellow31E), Insilico Royal Blue 31E becomes transparent when the temperature reaches 37°C. In this way, the flexible resin sheet is a deep peach pink (Korea Dawn FL503). Through the enlightenment of the present invention, those skilled in the art can choose different ratios according to their preferences and needs. By using different temperature-changing color powders and changing their proportions, different color change processes can be obtained, for example, royal blue to peach, rose to peach, green to yellow, orange to green, etc., which will not be described here.

As other optional embodiments, the flexible resin sheet may also be any one of TPV, TPO, SEBS, EPDM, and silicone rubber, and similarly, it is formed by an injection molding process.

In a more ideal implementation (not shown), in order to obtain a comparison effect, a second hot pressing area is provided on the mask body in the area where the elastic connecting portion is not located. The second hot pressing area is formed with a base color base layer by hot pressing, the base color base layer is provided with a reference color, and the reference color is consistent with the color displayed by the color changing part at the normal temperature of the human body. For example, in one embodiment, the resin made of TPE or TPU can be made of Formosa Plastics polypropylene PP5090T, Maoming Petrochemical LDPE2420K, ExxonMobil LLDPE6101, GLSTPEC3620 material, and LubrizolTPU58125. The ratio of toner to resin (mass percentage) is as follows, titanium dioxide (DuPont R-105): 0.04%-1%, temperature-changing golden yellow powder (Insilicoyellow31E): 0.08%-1%, temperature-changing Baolan toner ( InsilicoRoyalBlue31E): 0.32%-1%, pink powder (Korea Dawn FL503): 0.2%-1%, dispersant (ClariantPEWax3620): 0.12%-0.3%, resin: 95.7%-99.24%. The base color of the flexible resin sheet obtained by this ratio is purple. Starting at 35°C, the color of the flexible resin sheet changes from purple as the temperature increases. The specific color change process is: purple-light purple-light pink-dark peach Red, when the skin temperature sensed by the flexible resin sheet exceeds 37 degrees, its color will be deep pink. In the second hot pressing area, the reference color of the printing is purple or deep peach, and the ink sprayed in the second hot pressing area is an immutable ink, so that when the flexible resin sheet in the first hot pressing area produces color After the change, it is compared with the reference color of the second hot pressing area, so that it can be judged whether the body temperature of the mask wearer is abnormal.

Or, in a more ideal embodiment (not shown), a reference color table is provided on the mask body, and the reference color table identifies the color change portion displayed when the human body temperature/temperature range is different The current body temperature/body temperature range of the wearer can be obtained through the color displayed by the current color changing part. For example, in one embodiment, different color codes are set on the mask body, 35°C corresponds to purple, 35°C to 36°C corresponds to light purple, 36°C to 37°C corresponds to light pink, and when it is greater than 37°C Corresponding to dark pink, so that the current body temperature or body temperature range of the mask wearer can be judged according to the color displayed by the current discoloration part.

In all optional embodiments of the present invention, the mask body is provided with a nose bridge 106, which is made of a plastically deformed metal material, preferably an aluminum material. It can be embedded in the mask or glued to the outer surface of the mask. When used, it matches the nose bridge structure of the wearer to prevent the mask from sliding down, and it also plays a role in sealing the mask. For this part, I will not go into details here.

In the present invention, the thermochromic sticker can also be made first, and the thermochromic sticker is fixed on the mask. In this case, a preferred embodiment is to make the thermochromic sticker into a V-shaped clip shape. For the flexible resin sheet made as mentioned above, the flexible resin sheet wraps a thinner metal sheet, such as aluminum sheet, which has better plastic deformation, so that the thermochromic sticker can be clamped to the mask. On the inside of the mask, the thermochromic sticker is in contact with the facial skin to sense body temperature. Because of the metal sheet with good thermal conductivity, the metal sheet on the inside of the mask can quickly conduct heat to the metal sheet on the outside of the mask, so the same It can change the color of the thermochromic sticker. At the same time, this solution also realizes that the temperature-sensitive color-changing stickers can be reused.

With the mask of the present invention, the wearer’s body temperature can be observed immediately. When the wearer’s body temperature reaches or exceeds the warning value, medical testing can be carried out as soon as possible. At the same time, it can also alert others to the spread of the virus. efficient. On the other hand, the mask provided by the present invention has the effect of high aesthetics and pleasant mood.

In the foregoing embodiment, the color changing part 103 is arranged in the area where the non-elastic connecting part is located. In the foregoing embodiment, in this case, since the discolored part is located on the side of the human face, the attention of the external observer may be weakened.
