Embodiment one

1 to 3 are schematic diagrams of the structure of the anti-fog nose pad according to Embodiment 1 of the present utility model. As shown in the figure, the anti-fog nose pad structure 1 of the present embodiment includes an elastic liner 10, a reinforcing member 20 and a release film 30; and considering the practicability of the product, the thickness of the anti-fog nose pad structure 1 is 5mm～25mm, but the utility model is not limited thereto.

As shown in Figures 1 to 3, the elastic liner 10 can be made of light and highly elastic material, and has an airtight function; the material of the elastic liner 10 used in this embodiment can be listed as follows: foam , sponge, latex, silica gel, rubber, natural fibers, synthetic fibers, or analogs or derivatives of the above materials, but the utility model is not limited thereto. In more detail, the elastic pad 10 is an integrally formed and roughly wavy foam body, and in terms of structural design, one side (such as the outer side) of the elastic pad 10 has a flat joint surface 101 for reinforcement. 20 and the release film 30 are set; the other side (such as the inner side) of the elastic pad 10 is formed with two nose pads 102 separated by a certain distance, wherein the two nose pads 102 are each in an arc shape protruding outward, and the two A positioning slot 103 corresponding to the user's nose bridge is defined between the nose pads 102 .

The reinforcing piece 20 can be a metal strip, which has flexibility and good deformation resistance. Therefore, the reinforcing piece 20 is conformally arranged on the joint surface 101 and made along the elastic pad 10 Extending in the length direction can help maintain the integrity of the anti-fog nose pad structure 1 in use. In this embodiment, the reinforcing member 20 is made of an iron wire covered with a layer of plastic material on the surface. The function of the iron wire is to provide stiffness and strength, and the function of the plastic material is to increase the bonding force between the reinforcing member 20 and the elastic pad 10 .

The release film 30 is also conformally disposed on the joint surface 101 , and the size of the release film 30 is substantially consistent with the shape of the joint surface 101 . In this embodiment, the release film 30 includes a resin layer 301 formed on the joint surface and a release substrate 302 covering the resin layer 301, wherein the resin layer 301 is coated on the joint surface 101 and has adhesive on both sides. In this way, on the one hand, the resin layer 301 can fix the reinforcement 20 and the elastic liner 10 into one body, and on the other hand, it can temporarily bond the elastic liner combined with the reinforcement 20 to the mask; the function of the release base material 302 is to It can not only isolate the resin layer 301 from the outside, but also ensure that the adhesiveness of the resin layer 301 will not be damaged when the two interfaces are peeled off.

More specifically, the material of the resin layer 301 can be selected according to different purposes, and the material used in this embodiment is mainly polysiloxane layer (Siloxane). The release substrate 302 can be a release paper or a plastic film, wherein as the material of the release paper, kraft paper, Dowling paper, translucent paper or transparent paper can be selected, and the material of the plastic film can be selected polyethylene (Polyethylene) , PE), polypropylene (Polypropylene, PP), polyethylene terephthalate (Polyethyleneterephthalate, PET), polyurethane (Polyurethane, PU) or organosiloxane resin (silicon, Siloxane), etc., but the utility model It is not limited to this, and a special release substrate that has been toned can also be selected according to product requirements.

Please refer to Fig. 1 to Fig. 3, considering the convenience of use, release film 30 has a free end 31 and a fixed end 32 in structural design, and release base material 302 is not in contact with resin layer 301 at free end 31 Bonding, that is to say, the part of the release substrate 302 is not fully adhered to the surface of the resin layer 301 . The preferred design is that the anti-fog nose pad structure 1 also includes a clip 40 arranged on the free end 31 of the release film 30; in this embodiment, a part of the clip 40 is sandwiched between the release substrate 302 and between the resin layers 301, and can be fixedly connected to the joint surface 101 of the elastic pad 10 by means of the resin layer 301 at a position close to one end of the reinforcing member 20, so that the other part of the clip 40 is exposed at the free end 31, For the convenience of the user, the release substrate 302 can be easily peeled off.

Please refer to FIG. 3 to FIG. 6 together. The structural features of the anti-fog nose pad structure 1 of this embodiment have been described in detail above. Next, the use and operation of the anti-fog nose pad structure 1 will be briefly introduced. It is worth noting that since the elastic pad 10 can be compressed (or compacted) or stretched by external force according to its material properties, before the anti-fog nose pad structure 1 is joined to the mask M, it needs to be applied for a while. The external force changes the elastic liner 10 from the first operating position (such as the storage position, at this time the elastic liner 10 is in a compacted/compacted state) to the second operating position (such as the use position, at this time the elastic liner 10 is in a relaxed state) state); On the contrary, after the anti-fog nose pad structure 1 is used, it can apply force to compress the elastic liner 10 so that it returns from the second operating position to the first operating position. At this time, the elastic liner 10 is in the It becomes thinner when it is over-compressed, which is convenient for the user to store.

Next, the user can peel off the release substrate 302 from the position where the clip 40 is located, and use the resin layer 301 to contact the inside of the upper edge of the mask M, so as to join the anti-fog nose pad structure 1 and the mask M for use. Then, the user can utilize the ear straps (not shown) to put the mask M on to cover the mouth and nose and around the mouth and nose, and properly adjust the shape of the anti-fog nose pad structure 1 to make it more comfortable. Close to the contour of the user's face, wherein the groove shape of the positioning groove 103 of the elastic pad 10 matches the contour of the bridge of the user's nose. Accordingly, it can provide the user with the best stability and comfort when wearing the mask M, and it is difficult for the hot air exhaled to rise up to the eyes, so the anti-fog effect can be achieved.

Please refer to Table 1, the following will carry out several groups of experiments with the anti-fog nose pad structure 1 based on the elastic liner 10 of different foam specifications, in order to illustrate that the utility model can produce through the use of the elastic liner 10 in a specific density range technical effect.
