Abstract

The invention discloses a high-ventilation breathing filter placed in the nasal cavities. The breathing filter is characterized by being mainly composed of a pair of inner cages, a pair of filter bags and a pair of outer cages. When the breathing filter is used, the filter bags are arranged on the inner cages in a sleeving manner, and then the filter bags and the inner cages are placed into the outer cages together. The combined breathing filter is inserted into the nasal cavity, and then a user can breathe freely. As the skeleton structures of the outer cages stretch the inner walls of the nasal cavities open, the effective filtration area loss caused by large-area contact between the filter bags and the inner walls of the nasal cavities is avoided. Accordingly, the breathing filter is high in effective ventilation capacity and good in wearing stability and comfort performance. By using the breathing filter, dust, pollen and pathogenic microorganisms can be effectively prevented from entering the respiration system. Meanwhile, the influence on the attractiveness and the function of the mouth is avoided, and the breathing filter can care health of the respiration system of a wearer on any occasion all time.

Description

technical field [0001] The invention belongs to a breathing filtering device, in particular to a nasal cavity built-in breathing filtering device. Background technique [0002] Because there is a large amount of dust, pollen and pathogenic microorganisms suspended in the air, it has brought serious threats to people's respiratory system and even the health of the whole body. If it can effectively prevent dust and germs from being inhaled into the respiratory system, it is of great significance to human health. At present, the tool mainly used to filter dust, pollen and pathogenic bacteria in the air is a mask. Because traditional masks have many shortcomings such as poor wearing comfort, high cost, and high chance of being contaminated after coughing and sneezing, their use has many limitations. Especially when the weather is hot and the source of pollution is not very serious, wearing a mask is not only uncomfortable, but also unnecessary. In addition, in public places s...
