[0002] With increased public awareness of hygiene and health, masks have become ubiquitous as a protective tool in all aspects of our lives, including industries such as medical, chemical, and furniture manufacturing. In today's world, where industrialization has led to environmental pollution, we are compelled to wear masks when going out. The main function of these masks is to filter out microparticles, viruses, and harmful gases, preventing them from being directly inhaled and causing negative health effects. There are many types of masks available, with sheet masks and folding masks being the most common. Sheet masks consist of several layers of filter sheets laid flat and overlapping; folding masks have multiple horizontal folds on these layers, which are pulled up and down to be worn. However, existing folding masks merely reduce the packaging area by creating horizontal folds, which does not significantly improve filtration efficiency. Furthermore, they are difficult to maintain their shape after being pulled open, further reducing filtration effectiveness. Utility Model Content

[0039] Embodiment 1

[0040] Referring to the drawings Figure 1 , a mask with a folded breathable layer in the present embodiment is provided with at least one non-transversely extended folding portion 110 in the breathable area of the mask body 100, which is a folded breathable filter layer. In use, unfolding the folding portion 110 can increase the area of the breathable area of the mask body 100, thereby improving the filtering effect, and can accommodate more exhaled gas, effectively preventing gas from overflowing from the upper end of the nose and the chin, thereby further improving the filtering effect. The non-transversely extended folding portion 110 can provide certain strength support to the breathing cavity formed by unfolding the mask body 100 as a whole, prevent the breathing cavity from shrinking and expanding during the breathing process, and thereby avoid the generation of air leakage.

[0041] The folding part 110 includes a non-transversely extending multi-layer material ruffle 111 arranged in the left and right body surfaces of the mask body 100, wherein each body surface includes a nose surface, a middle surface and a chin surface. Each body surface includes a continuous ruffle 111 extending through the nose surface, the middle surface and the chin surface; and one end of the ruffle 111 in the nose surface area of each body surface of the mask body 100 is sealed with itself to form a first sealing area, and the other end of the ruffle 111 in the chin surface area is sealed with itself to form a second sealing area.

[0042] Specifically, the number of folded layers of the folding part 110 is at least one, and the number of folded layers can be adjusted according to specific use, the more the number of folded layers, the larger the respiratory cavity volume formed after the folding part 110 is unfolded, and the better the filtering area and filtering effect.

[0043] The folding area or unfolded area of the folding part 110 accounts for 5%-60% of the overall unfolded area of the mask, and can also be preferably any one of 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%. Adjusted according to specific use, the larger the proportion, the larger the respiratory cavity volume formed after the folding part 110 is unfolded, and the better the filtering area and filtering effect.

[0044] The folding part 110 is configured to have better air permeability and filtering effect than the non-folding part area of the mask, and the material used in the folding part 110 can be polypropylene electrostatically charged material, glass fiber filter material, PET filter material, etc. It can effectively ensure that most of the exhaled gas is filtered to the outside through the cavity formed after the folding part 110 is unfolded, avoiding the problem of exhaled gas overflowing from other areas due to low filtering efficiency.

[0045] The folding part 110 is configured to be any one of a relative symmetrical "eight" shape, an inverted "eight" shape, a "V" shape, an inverted "V" shape, a "U" shape, an inverted "U" shape, an "M" shape, and an inverted "M" shape along the longitudinal axis in the use state. The shape is not limited to these structures listed, and other shapes that can wrap the nose to form a cavity are also feasible.

[0046] The folding part 110 is configured to unfold along the sides of the nose in the use state to facilitate convenient wrapping of the nose to form a breathing cavity, so that the exhaled gas from the nose first contacts the unfolded folding part 110, thereby improving the filtering effect.

[0047] The folding layer thickness or size of the folding part 110 with at least two folding layers gradually decreases along the direction close to the nose, so that the folding part 110 gradually decreases in size along the direction close to the nose when unfolded, thereby better fitting the shape of the breathing cavity formed by the folding part 110 along the nose. The folding layer thickness or size of the folding part 110 with at least two folding layers gradually decreases along the direction close to the edge of the mask. It can be ensured that the folding part 110 is closer to the skin and effectively reduces the possibility of air leakage when approaching the edge of the mask.

[0048] The folding part 110 is provided with a crease for shaping, and the crease is made of plastic material. The folding part 110 can be conveniently maintained in a folded state by the crease made of plastic material, facilitating packaging and transportation.

[0049] The mask body 100 is also provided with a nose clip 120, and the mask body 100 is also connected with a belt 130. The nose clip 120 can effectively clamp and fix the area close to the nose on the upper end of the mask body 100, reduce the gap with the skin, and reduce the possibility of air leakage.

[0050] The folding direction of the folding part 110 is inward or outward folding. Inward folding or outward folding can make the folding part 110 accommodated inside or outside the mask body 100. In this embodiment, inward folding is preferred. Accommodating the folding part 110 inside the mask body 100 can make the surface appearance of the mask body 100 not affected.

[0051] The folding part 110 is integrally folded or partially folded. In this embodiment, partial folding is preferred, which can reduce production cost and manufacturing difficulty.

[0052] The folding part 110 is continuously folded or discontinuously folded. When discontinuous folding is selected, the area of the foldable region occupying the overall area should meet the minimum folding and unfolding requirements of the folding part 110.

[0053] The folding part 110 includes a bending region and an expansion region, and the bending region is configured to have greater flexibility and bending performance than the expansion region. The expansion region is provided with a reinforcing pattern for supporting the expansion performance. The connection area of the mask body 100 and the folding part 110 is provided with a bending reinforcing pattern for assisting the expansion and unfolding of the folding part 110. The shape of the bending reinforcing pattern is adapted to the edge shape of the folding part 110 after expansion. The mask body 100 is also provided with a welding line or reinforcing pattern for supporting the shape of the mask.

[0054] The above-described embodiments only express certain implementation manners of the present application, and the description is relatively specific and detailed, but should not be understood as a limitation on the scope of the present application; it should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
