Abstract

The invention relates to a nasal air filter device, in particular to a nasal air filter device that is worn without touching the face, which solves the problems that existing masks and nasal masks have many defects in actual use, including being flat on the face of the human body The front air filter cover body and the airtight air passage assembly arranged between the air filter cover body and the nostril; the air filter cover body includes a hollow shell, an air filter assembly arranged in the hollow shell, and an air filter assembly arranged in the hollow shell The air hole on the back and communicates with the inside; the middle position of the back of the hollow shell is provided with a nose accommodating groove, and the air holes are symmetrically opened on both sides of the nose accommodating groove. The nostrils are connected, the hollow shell is a closed cavity, and at least one long strip-shaped insertion port of the air filter assembly is provided on the lower end surface or the left and right sides. The structure design is reasonable and ingenious, the wearing is convenient and comfortable, the filtering effect is good, and the utility model has good popularization and application value.

Description

technical field [0001] The invention relates to a nasal air filter, in particular to a nasal air filter which is worn without touching the face. Background technique [0002] When we live and work in an air-polluted environment, we will inevitably inhale harmful substances such as floating dust, germs, and PM2.5 in the air, which will affect our health. For this reason, many people will choose to wear a mask for protection, but there are the following defects in actual use. Wearing a mask in summer is easy to be stuffy; in winter, the breath exhaled by wearing a mask will fog up the lens of the person wearing glasses and affect the line of sight; The aesthetics behind the mask is not good; and it affects speech and communication. [0003] Aiming at the deficiencies in the technology of the masks currently on the market, relevant technicians have invented nasal masks, such as the nasal mask with the patent No. Although the new technology makes up for some deficiencies in th...
