AI Technical Summary
[0002]口罩是人们日常生活中的一种常备用品,医用时可以作为一种防护用具预防传染,平时可以作为一种佩戴品用来防晒或者装饰,由于口罩在佩戴时口和鼻都处于口罩覆盖的同一个空间,这导致口腔呼出的气体(含有病菌和二氧化碳)在鼻子吸气的时候会吸入鼻腔内,给佩戴者造成较大的不适感
[0006] The beneficial effects of this utility model are as follows: by setting an inner layer, the nose and mouth are respectively placed in two spaces, and in order to facilitate the expulsion of exhaled air from the mouth, an air guide groove is also set on the inner layer. After exhaling through the mouth, the air in the oral cavity can be discharged from both ends of the inner layer through the air guide groove. In this way, without filtering, it can effectively prevent the air exhaled from the mouth from being re-inhaled through the nose when worn for a long time.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mask technology, and in particular to a mask that prevents bad breath. Background Technology
[0002] Masks are a common item in people's daily lives. They serve as protective gear to prevent infection in medical settings and are worn for sun protection or decoration. However, because the mouth and nose are covered by the mask, exhaled air (containing germs and carbon dioxide) is inhaled into the nasal cavity, causing significant discomfort. To address this issue, patent document CN217658275U discloses a mask that prevents bad breath. Its technical solution uses an insulating filter to divide the mask's inner cavity into two parts, separating the nose and mouth areas. Air from the mouth is filtered through the filter, absorbing odor molecules before reaching the nose, thus filtering nasal air. The drawback of this solution is that it only filters and absorbs exhaled air from the mouth; exhaled air is not easily expelled, and its effectiveness decreases with use, failing to effectively prevent nasal air from entering the nasal cavity. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose an anti-bad breath mask, which separates the nose and mouth so that the air exhaled from the mouth can be discharged separately, thereby avoiding being re-inhaled into the nasal cavity.
[0004] To achieve this objective, the present invention adopts the following technical solution: This utility model provides an anti-bad breath mask, comprising a mask body with adhesive points for connecting straps near its four corners for easy wearing; an inner layer for the face, fitted to the mouth, with its top positioned between the nose and upper lip; a fixing part (seamlessly sewn) between two elastic pieces; several air channels extending from the center of the inner layer to both ends, so that the two ends of the inner layer fit against the cheeks when worn; elastic pieces embedded at both ends of the inner layer, each with an exhaust port that mates with the air channels, and a skin-friendly layer on its surface; and pleats for the nose to expand the breathing space through the nostrils when worn.
[0005] Preferably, the inner interlayer and the mask body can be detachable by clips, the fixing part is an adhesive part, the adhesive part is strip-shaped, and the adhesive part is disposed between the two elastic sheets; the adhesive part is Velcro.
[0006] The beneficial effects of this utility model are as follows: by setting an inner layer, the nose and mouth are respectively placed in two spaces, and in order to facilitate the expulsion of exhaled air from the mouth, an air guide groove is also set on the inner layer. After exhaling through the mouth, the air in the oral cavity can be discharged from both ends of the inner layer through the air guide groove. In this way, without filtering, it can effectively prevent the air exhaled from the mouth from being re-inhaled through the nose when worn for a long time. Attached Figure Description

[0008] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0009] To address the discomfort caused by exhaled air being re-inhaled into the nasal cavity during prolonged mask wearing, this invention provides an anti-haze mask, which is specifically described through the following two preferred methods: Example 1: A mask to prevent bad breath, such as Figure 1 and 4As shown (without straps), the mask includes a mask body 1. The mask body 1 has adhesive points 11 near its four corners for connecting straps to facilitate wearing. Furthermore, the mask body 1 has an inner layer 2 near the face that fits around the mouth. The top of the inner layer 2 is located between the nose and the upper lip (the philtrum). A fixing part 3 is provided between the top of the inner layer 2 and the mask body 1 to connect the inner layer 2 and the mask body 1. When worn, the inner layer 2 and the face form a space for exhaling through the mouth (mainly during speaking and exhalation), while the inner layer 2 and the mask body 1 together form a breathing space for the nostrils (mainly during normal breathing). The mask body 1 also has pleats that fit around the nose to expand the nasal breathing space after wearing. Thus, the air exhaled during speaking and exhalation can pass through the space formed between the inner layer 2 and the face. For optimal airflow, the inner layer 2 has several air-guiding grooves 21 on the side near the face to assist in expelling exhaled air. These grooves extend from the middle of the inner layer 2 to both ends. When worn, the two ends of the inner layer 2 are in contact with the cheeks. Thus, after exhaling, the air in the mouth can be expelled through the air-guiding grooves 21 from both ends of the inner layer 2, eliminating the need for filtration. This effectively prevents exhaled air from being re-inhaled through the nose even during prolonged wear and can be widely used in various types of masks, such as N95. Furthermore, to prevent the two ends of the inner layer 2 from being too tight and unable to effectively expel exhaled air, elastic sheets 22 are embedded at both ends of the inner layer 2. The elastic sheets 22 have exhaust ports 221 that cooperate with the air-guiding grooves 21. To ensure comfort during wear, the surface of the elastic sheets 22 is covered with a skin-friendly layer.
[0010] In order to make the two ends of the inner layer 2 relatively independent so that it can better wrap around the mouth, the fixing part 3 is a sewing part, which is strip-shaped and is located between the two elastic pieces 22; in this way, the elastic pieces 22 embedded at both ends of the inner layer 2 can effectively fit the cheeks individually while ensuring the effective discharge of exhaled air.
[0011] Example 2: The difference from Example 1 is that, as Figure 3 and 4 As shown, the fixing part 3 is an adhesive part, which is strip-shaped and is located between two elastic sheets 22. Thus, the inner layer 2 and the mask body 1 are designed to be detachable, so that the appropriate inner layer 2 can be replaced as needed during actual use. More specifically, the adhesive part is Velcro.
[0012] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
