Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of masks, in particular to a mask with a breathing buffer cavity. Background Art
[0002] With increasing awareness of hygiene and health, masks have become a ubiquitous protective tool in various fields of life, such as healthcare, chemicals, and furniture manufacturing. However, with the increasing environmental pollution caused by industrialization, we now have to wear masks when traveling to avoid the harmful effects of smog. The primary function of these masks is to isolate and filter microparticles, viruses, and harmful gases, preventing them from being directly inhaled into the lungs and causing negative health effects. There are many types of masks available, with sheet masks and folding masks being the most commonly used. Sheet masks consist of several layers of overlapping filter sheets, while folding masks feature multiple horizontal folds on these layers of overlapping filter sheets, allowing them to be pulled apart when worn. However, existing folding masks often struggle to effectively seal against the wearer's body due to the mask edges. During exhalation, the wearer experiences a sudden increase in air pressure, causing a large amount of exhaled air to escape from the mask edges, significantly impacting the mask's filtering effectiveness. Existing masks typically address this issue by improving the sealing properties of the mask edges, but this approach increases manufacturing costs and compromises the wearer's experience.

[0040] Embodiment 1
[0041] Referring to the drawings Figure 1 and Figure 2 , the enlarged area in Figure 1 is a sectional view of the hem 111; Figure 2 is an example of the shape of the flow guide part 112.
[0042] A breathing buffer cavity 140 for blocking and filtering the nose exhaled gas is arranged in the breathable area of the mask body 100; the breathing buffer cavity 140 at least includes a folding part 110, and the folding part 110 at least includes a flow guide part 112 arranged on the nose exhaled gas path and used for guiding the downward flow of the nose exhaled gas upward. When the user wears the mask to breathe, the nose exhaled gas will be sprayed downward along the direction of the nose. In the process of the exhaled gas being sprayed downward, the flow guide part 112 can hinder the exhaled gas to a certain extent, reduce the amount and air pressure of the exhaled gas directly flowing downward, prevent the exhaled gas from overflowing from the gap between the lower end of the mask body 100 and the chin of the wearer, and thus reduce the filtering effect; and the exhaled gas is guided upward to be retained and circulated in the breathing buffer cavity 140, so as to ensure that most of the exhaled gas is filtered and discharged through the breathing buffer cavity 140, effectively ensuring the filtering effect of the mask body 100.
[0043] The shape of the flow guide part is matched with the size of the breathing buffer cavity to reversely guide the downward flow of the nose exhaled gas. When the size of the breathing buffer cavity 140 increases, the shape and size of the flow guide part 112 are set to increase in coordination, so as to ensure the hindering effect. The flow guide part 112 forms a flow guide channel having a part for guiding the airflow upward. The retention and circulation of the exhaled gas in the breathing buffer cavity 140 can be further promoted, so as to ensure that most of the exhaled gas is filtered and discharged through the breathing buffer cavity 140, effectively ensuring the filtering effect of the mask body 100. The flow direction of the flow guide channel is configured such that the guided airflow does not directly impact the inner wall of the breathing buffer cavity 140 to circulate in the breathing buffer cavity 140, so as to ensure the uniform air pressure in the breathing buffer cavity 140.
[0044] The size of the flow guide part is matched with the efficiency of reverse flow guiding of the nasal orifice exhaled gas, and the gas guided by the flow guide part accounts for 50-90% of the total exhaled gas volume. The specific configuration is related to the material of the mask body 100 forming the breathing buffer cavity 140 and the material of the folding part 110. When the air permeability and filtering effect of the material of the mask body 100 forming the breathing buffer cavity 140 and the material of the folding part 110 are better, the proportion of the gas guided by the flow guide part in the total exhaled gas volume is larger, so that almost all the gas is filtered and discharged through the mask body 100 and the folding part 110 forming the breathing buffer cavity 140, thereby effectively ensuring the filtering effect of the mask body 100.
[0045] The folding part 110 includes a plurality of layers of non-transversely extending material pleats 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 pleat 111 extending through the nose surface, the middle surface and the chin surface; and one end of the pleat 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 pleat 111 in the chin surface area is sealed with itself to form a second sealing area.
[0046] Specifically, the folding part 110 has at least one folding layer, and the number of folding layers can be adjusted according to specific use. The more the number of folding layers, the larger the volume of the breathing cavity formed after the folding part 110 is unfolded, and the better the filtering area and filtering effect.
[0047] The folding area or unfolded area of the folding part 110 accounts for 5-60% of the total unfolded area of the mask, and can also be any one of 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%. According to specific use, the larger the proportion, the larger the volume of the breathing cavity formed after the folding part 110 is unfolded, and the better the filtering area and filtering effect.
[0048] 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 by the folding part 110 can be polypropylene electrostatically charged material, glass fiber filtering material, PET filtering material, etc. It can effectively ensure that most of the exhaled gas is filtered through the cavity formed after the folding part 110 is unfolded to the outside, avoiding the problem of exhaled gas overflowing from other areas due to low filtering efficiency.
[0049] The folding part 110 is configured to expand the area along the two sides of the nose in the use state, so as to facilitate the convenient wrapping of the nose to form a breathing cavity, which can make the gas exhaled by the nose first contact the expanded folding part 110, thereby improving the filtering effect.
[0050] 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 size of the folding part 110 gradually decreases along the direction close to the nose when it is unfolded, thereby better making the breathing cavity formed by the folding part 110 along the mask fit the shape of 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 better close to the skin and effectively reduces the possibility of air leakage when it is close to the edge of the mask.
[0051] The folding part 110 is provided with a crease for shaping, and the crease is made of plastic material. The crease made of plastic material can conveniently make the folding part 110 maintain the folded state, and facilitate packaging and transportation.
[0052] 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 of the upper end of the mask body 100 close to the nose, reduce the gap with the skin, and reduce the possibility of air leakage.
[0053] The folding direction of the folding part 110 is inward or outward folding. Inward folding or outward folding can make the folding part 110 be contained inside or outside the mask body 100. In this embodiment, inward folding is preferred. Containing the folding part 110 inside the mask body 100 can make the surface appearance of the mask body 100 not be affected.
[0054] The folding part 110 is integrally folded or partially folded. In this embodiment, partial folding is preferred, which can reduce the production cost and manufacturing difficulty.
[0055] The folding part 110 is continuously folded or discontinuously folded. When discontinuous folding is selected, the area of the foldable region occupying the whole area should meet the minimum folding and unfolding requirements of the folding part 110.
[0056] The folding part 110 comprises a bending area and an expansion area, the bending area is configured to have greater flexibility and bending performance than the expansion area. The expansion area 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 matched with the edge shape of the expanded and unfolded folding part 110. The mask body 100 is also provided with a welding line or a reinforcing pattern for supporting the shape of the mask.
[0057] The above-mentioned embodiments only express certain implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent 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.
