Technical Field

[0001] The utility model relates to a mask, in particular to an anti-nasal allergy mask, belonging to the technical field of masks. Background Art

[0002] With the continuous development of cities, air pollution is becoming more and more serious, and the number of patients with allergic rhinitis and asthma is also increasing, which seriously affects people's daily life and work. Allergic rhinitis and asthma are common respiratory diseases. They are often caused by allergens such as pollen, dust mites, animal dander, volatile organic compounds in the air. Traditional treatments include drug therapy and avoiding contact with allergens, but both methods have their limitations. Drug therapy may have certain side effects, and completely avoiding contact with allergens is often difficult to do in modern society. Therefore, it is necessary to wear a mask to reduce the inhalation of allergens. Although there are various masks on the market, most of them only have simple dust or antibacterial functions and cannot effectively alleviate nasal allergy symptoms. Moreover, the common masks on the market cannot be used for a long time or multiple times.

[0003] Therefore, designing an anti-nasal allergy mask that can alleviate asthma and rhinitis has very important practical significance for improving the quality of life of patients. Utility Model Content
