technical field

The present invention relates to a mask, in particular to a mask with anti-fog or fog-reducing functions.

Background technique

Fig. 8 is the appearance diagram of the relevant plane cloth mouth mask in the prior art, and Fig. 9 is the appearance diagram of the relevant three-dimensional mouth mask in the prior art. At present, commercially available masks can be roughly divided into flat masks in Fig. 8 and three-dimensional masks in Fig. 9 according to their different shapes, which mainly include a mask body 11 and ear straps 14, but whether it is a flat mask or a three-dimensional mask, although it can It achieves the basic functions of dustproof and waterproof, but when in use, the heat exhaled by the user will cause the glasses to fog up, which is very inconvenient, especially when driving or riding a motorcycle, the fogging of the glasses will cause the vision to be unclear, which is not suitable for driving or riding. In other words, it is not only inconvenient but also the danger of a car accident.

Therefore, how to overcome the problem of fogging when the mask is used is an important issue in this case.

Contents of the invention

Detailed ways

First embodiment:

Please refer to Figures 1 to 3, the present invention is to provide a mask with anti-fog or fog-reducing function, which includes a mask body 11, and an exhaust structure 12 is arranged on the inner side of the lower edge of the mask body 11. The structure 12 has a through hole 121. When the mask is in use, the exhaled air passes from the inside of the mask to the outside through the through hole 121. Therefore, the exhaled hot air can be discharged through the lower through hole 121 of the mask body 11 to reduce or cut off the flow of hot air from above. .

As mentioned above, the exhaust structure 12 is mainly provided with a shorting body 122 inside the lower edge of the mask body 11, and a shorting position 123 is preset on the mask body 11 corresponding to the shorting body 122 to fix the The two ends of the shorting body 122, and the length d1 of the shorting body 122 is less than the length of the shorting position 123d2, so that when the two ends of the shorting body 122 are fixed at the two ends of the shorting position 123, the exhaust structure 12 is formed. through hole 121 .

Please refer to Fig. 1A, in the embodiment of Fig. 1, both ends of the shorting body 122 are fixed at the shorting position 123, and in the embodiment of Fig. 1A, at least one side of the shorting body 122 can be glued The buckle set 125 is glued to the shorting position 123 . In addition, a filter 124 as shown in FIG. 3A may be provided at the position of the through hole 121 of the aforementioned exhaust structure 12 to filter dirt and dust so that external dirt and dust are not sucked in. Typical materials such as cotton cloth, Gauze or traditional filter materials, etc.

Please refer to Figures 1 and 4, the present invention is further provided with an air-blocking pad 13 inside the upper edge of the mask body 11, so that when the mask is used on the face, the gap between the upper edge of the mask body 11 and the face can be covered by the air-blocking pad. 13 stuffing.

The air-blocking pad 13 of the present invention is a strip made of sponge or foaming material but not limited to this material, which can be deformed according to the shape of the human face, and has comfort and fit to the face in contact with it. and air tightness.

In addition, the present invention provides a flexible nose clip 131 in the air-blocking pad 13 or on the surface of the air-blocking pad 13. The nose clip 131 has the characteristics of being bendable and shaped, and can bend the shape of the air-blocking pad 13 to fit the human body. The shape of the face makes the mask body 11 and the air-blocking cushion 13 very close to the face. With the elastic material of the air-blocking cushion 13, its airtightness is greatly improved, making it difficult for the exhaled hot air to escape from both sides of the bridge of the nose. to the eyes, so it has an anti-fog effect for glasses.

In the mask embodiment of the present invention, ear straps 14 are provided on both sides of the mask body 11, which are generally traditional elastic ear straps 14, so that users can hang the mask on the ears on both sides.

The above is a description of the structure of the present invention. When using the mouth mask of the present invention, please refer to shown in Figure 5. Utilize the ear strap 14 to cover the mouth and nose with the mouth mask body 11 of the mouth mask, and adjust the air blocking pad 13 above the bridge of the nose, and Press or squeeze with your hands to adjust the nose clip 131 to match the shape of the human face, and make the air-blocking cushion 13 stick to the corresponding facial position to give it a shape, and adjust its comfort with the face And achieve the best airtight effect. The shorting body 122 on the lower edge of the mask body 11 is then attached between the lips and the chin, and when the shorting body 122 is tight, a through hole 121 then appears between the shorting body 122 and the shorting position 123 of the mask body 11, so , when using this mask, the exhaled hot air can be discharged downward by means of the through hole 121, and the effect of preventing the hot air from scurrying upwards by means of the air blocking pad 13 can fully achieve the purpose of anti-fog.

Second embodiment:

FIG. 6 is a front appearance view of the second embodiment of the present invention, and FIG. 7 is a rear appearance view of the second embodiment of the present invention.

The present invention is to provide a mask with anti-fog or fog-reducing function, which includes a mask body 11, on the mask body 11 is provided with an exhaust structure 12, an air-blocking cushion 13, and an ear strap 14 as in the first embodiment Etc., the exhaust structure 12 has the through hole 121, the short-circuit body 122, the short-circuit position 123, etc. in the first embodiment. I won't go into details. Its difference is: the central position of mouth mask body 11 has a three-dimensional cover portion 15, makes this case mouth mask become a three-dimensional mouth mask, utilizes three-dimensional cover portion 15 to make mouth and nose portion can not contact mouth and nose portion, and mouth mask can not be stained with lipstick, saliva, nasal mucus, etc., to ensure hygienic use.

Certainly, the mask in this case is not limited to the plane mask and the three-dimensional mask of the aforementioned first and second embodiments, and can also be applied to a neck mask (not shown), so that the neck mask also has anti-fog or fog-reducing functions. Since the neck protection mask is provided with a neck protection structure at the bottom of the plane or three-dimensional mask, and the parts of the mouth mask are the same as those in the first and second embodiments, no further details are given here.

The above is only a preferred embodiment of the present invention, and should not limit the scope of the present invention with this, that is, all simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the description of the invention should be Still belong to the scope that the patent of the present invention covers.
