Description

Technical Field

[0001] This utility model relates to the field of mask technology, specifically a mask that reduces the bending strength of the nose bridge shaping strip area to improve fit. Background Technology

[0002] The types of face masks are becoming increasingly diverse, with many types available on the market that are oil-proof, formaldehyde-proof, and odor-proof. In this context, to cope with multiple sources of pollution, face mask manufacturers have had to incorporate various filter materials into their masks.

[0003] Adding these filter materials increases the thickness of the mask, making it less prone to folding. Specifically, thicker fabric increases the mask's stiffness, which in turn counteracts the bending of the nose bridge shaping strip. This makes it less likely for the nose bridge shaping strip to be molded into a shape that fits snugly against the wearer's nose.

[0004] When the stiffness of a mask increases while maintaining its airtightness, current technology uses thicker or coarser nose bridge shaping strips to forcibly reshape the mask. This method requires increased material costs and greater control during shaping, but it does not solve the fundamental problem.

[0005] In conclusion, increasing the thickness not only reduces the mask's shaping effect but also decreases the fit between the mask and the skin, which needs improvement. Utility Model Content

[0006] The purpose of this invention is to provide a mask that reduces the bending strength of the nose bridge shaping strip area to improve fit, thereby solving the problem in the prior art where increased mask thickness leads to poor mask shaping effect and reduced fit between the mask and the skin surface.

[0007] To achieve the aforementioned utility model objective, the technical solution adopted by this utility model is: a mask that reduces the bending strength of the nose bridge shaping strip area to improve fit, comprising:

[0008] The main body includes an inner layer, an outer layer, and several intermediate layers sandwiched between the inner and outer layers, used to filter air pollutants;

[0009] A nose bridge shaping strip is provided at the top of the main body to deform the top of the main body so as to fit the user's nose bridge.

[0010] Wearable device, connected to the main body, for wrapping around the user's ears or head and neck to achieve wearing of the main body;

[0011] The top of the main body has at least one layer that tapers downwards to below the nose bridge shaping strip, used to reduce the thickness of the mask in that area.

[0012] According to some embodiments of the present invention, the bottom of the main body has at least one layer that is tapered upwards, which is also used to reduce the thickness of the mask in that area.

[0013] According to some embodiments of the present invention, the ends of the reduced layers at the top and bottom of the main body are both in a straight line parallel to the nose bridge shaping strip.

[0014] According to some embodiments of the present invention, the end of the reduced layer at the top of the main body is in the shape of a clamp enclosing the nose bridge shaping strip on three sides.

[0015] According to some embodiments of the present invention, the gap between the end of the reduced layer at the top of the main body and the nose bridge shaping strip is 2-40mm.

[0016] The beneficial effects of this utility model are mainly reflected in:

[0017] First, we reduced the stacking at the edges of the main body through structural design, and thinned the nose bridge shaping strip of the mask separately. The thinner edges of the mask are more likely to deform with the facial contours, reducing gaps and ensuring airtightness. Other areas maintained their original thickness to maintain overall protective performance.

[0018] Secondly, even after adding several layers to the middle layer of the mask, this design does not require increasing the strength of the nose bridge shaping strip, thus saving costs. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Example 1

[0032] Please see Figures 1-6 A mask that reduces the bending strength of the nose bridge shaping strip area to improve fit, which can be used in daily masks, medical masks or industrial masks.

[0033] The mask includes a main body 1 for filtering air pollutants. The main body 1 includes an inner layer 2, an outer layer 3, and several intermediate layers 4 sandwiched between the inner layer 2 and the outer layer 3.

[0034] Intermediate layer 4 may include a first intermediate layer, a second intermediate layer, and a third intermediate layer.

[0035] Of course, the above structural design of inner layer 2, outer layer 3 and middle layer 4 are just some commonly used implementation methods, and there can be other layer architectures.

[0036] A nose bridge shaping strip 5, located at the top of the main body 1, is used to deform the top of the main body 1 to fit snugly against the user's nose bridge. The nose bridge strip 2 can be made of a material with low resilience to improve the fit between the mask and the body. The nose bridge shaping strip 5 can be made of flexible metal (such as aluminum) or wrapped with wire. The width of the nose bridge shaping strip 5 is 2.5-10mm, and the thickness is 0.3-1mm.

[0037] Wearing piece 6 is connected to the main body 1 and is used to wrap around the user's ears or head and neck to enable the main body 1 to be worn.

[0038] The top of the main body 1 has at least one layer that tapers downwards to below the nose bridge shaping strip 5, which is used to reduce the thickness of the mask in that area.

[0039] The intermediate layers 4 can be at least one layer of reduction treatment or multiple layers of reduction treatment. The former is suitable for masks with relatively few intermediate layers 4, and the latter is suitable for masks with relatively many intermediate layers 4. The number of reduction treatment layers is set according to the actual situation.

[0040] Generally speaking, by thinning the nose bridge shaping strip of the middle layer 4 separately, the thinner edge of the mask is more likely to deform with the facial contour, reducing gaps and ensuring airtightness, while other areas maintain their original thickness to maintain overall protective performance.

[0041] The end of the reduced layer at the top of the main body 1 is in a straight line parallel to the nose bridge shaping strip 5. A straight end is the preferred embodiment because it minimizes the number of steps involved in cutting the reduced layer, requiring only the trimming of excess scraps, and thus placing minimal demands on the cutting equipment. Alternatively, directly purchasing a small intermediate layer 4 is even simpler.

[0042] The gap between the end of the reduced layer at the top of the main body 1 and the nose bridge shaping strip 5 is 2-40mm to form a suitable reduction area.

[0043] In another embodiment, the end of the reduced layer at the top of the main body 1 is in the shape of a clamp that surrounds the nose bridge shaping strip 5 on three sides. This clamp shape is concave to form three inner sides. For simplicity, we will describe the clamp shape by means of a clearance notch 7. Similarly, the clearance notch 7 reduces the thickness of the mask in this area. In addition, the area of ​​the clearance notch 7 is larger than the area of ​​the nose bridge shaping strip 5 to avoid the nose bridge shaping strip 5.

[0044] The clearance notch 7 is provided around the bottom, left, and right sides of the nasal bridge shaping strip 5. Because the clearance notch 7 encloses the nasal bridge shaping strip 5 on three sides, the spacing between them is shortened, thus minimizing the reduction area of ​​the reduced layer. This three-sided enclosure arrangement preserves the integrity of the intermediate layer 4 to the greatest extent possible.

[0045] According to some embodiments of this utility model, in order to further improve the fit of the mask and make the bottom of the mask fit better against the wearer's chin, the bottom of the main body 1 has at least one layer that is tapered upwards, which also reduces the thickness of the mask in this area. The end of the tapered layer at the bottom of the main body 1 is also in a straight line parallel to the nose bridge shaping strip 5. For ease of description, this downwardly tapered area is collectively referred to as the lower relief area 8, which also reduces the thickness of the mask in this area. The area of ​​the lower relief area 8 can be equal to or unequal to the area of ​​the relief notch 7, and can be set as needed. This makes both the top and bottom of the mask thinner and provides a better fit.

[0046] This embodiment only provides a drawing of a mask with a conventional shape. The mask may also have other shapes, and this design scheme applies to all of them.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
