As shown in figure 23, transition member 4 in nose air filter is provided with check valve 7, this check valve 7 adopts rubber to make, for controlling the control valve of airflow direction, when human body air-breathing, check valve 7 is closed, need filtered air after filtration diaphragm 101 filter after, member lumens 103 to nose exocoel 22 after filtration; As human exhaled breath, check valve 7 is opened, and the gas of characteristics of contaminated respiratory droplets is directly discharged by check valve 7 through nose exocoel 22.Certainly, this check valve 7 also can be arranged on the filtration membrane 101 of air filtering assembly 1, and just when human exhaled breath, check valve 7 is opened, the gas of characteristics of contaminated respiratory droplets enters air filtration inner chamber 103 through nose exocoel 22, and the check valve 7 after filtration diaphragm 101 opened is discharged.

As shown in figure 23, nose air filter also comprises through hole seal 43, this through hole seal 43 adopts silica gel material vulcanizing treatment to make, be positioned at transition member through hole 41 inner, or be positioned at the side that transition member through hole 41 does not connect air filtering assembly 1, mainly transition member through hole 41 sealing closed.The filter element inner chamber 103 of nose exocoel 22 with air filtering assembly 1 is separated by this through hole seal 43, first, try the model that nose air filter will select nose adhesive parts 2 corresponding with examination wearer nasal contours on, by human body nostril air-breathing, the air that nose exocoel 22 holds is pumped trying in process, form negative pressure state, if now nose air filter is worn on human body nose certain hour and does not come off, namely can think that nose adhesive parts 2 is applicable to the nasal contours of wearer, and nose adhesive parts 2 and accessory 8, transition member 4 sealing is good, the second, through hole seal 43 can ensure air filtering assembly 1 clean hygiene before use.

As shown in Figure 24,25, described nose air filter is worn on around human body nose, and wearing mode can be utilize the frenulum fixture 63 on face-piece 6 to connect to have flexible frenulum 82, and frenulum 82 is hooked on human body ear, or lies in human body head.Wear correctly, human body nose is covered by nose air filter part or all covers, human body mouth area is released in device outside, for ensureing that nose air filter and human body nose surrounding skin 9 are tightly connected, the body profile of above-mentioned nose adhesive parts 2 and human nasal contouring conformal, and adopt the sulfuration of silica gel material to make, comparatively soft, so the nose connector 21 of nose adhesive parts 2 can be fitted with human body nose surrounding skin 9 sealing, space now between nose adhesive parts 2 interior surface and human body nose surrounding skin 9 surface is formed, this space is nose exocoel 22, the nostril of human body is contained in nose exocoel 22 inside.

As shown in figure 25, after nose air filter is worn on human body nose, because human body self breathes the kinetic energy effect produced, device outside need filtered air can face-piece opening 61 access to plant on face-piece 6 inner, first through the blow vent 52 of coating member 5, enter the spatial accommodation 51 that coating member 5 connects to form with transition member 4, this spatial accommodation 51 inside accommodates two groups of air filtering assemblies 1, filter area is increased in order to maximize in small space, reduce respiratory resistance, so this air filtering assembly 1 is provided with the first filter element 11 and the second filter element 12, need the filter element that the autonomous chosen position of filtered air is nearer, filtered by the filtration membrane 101 on this filter element again, air after filtration enters the transition member through hole 41 of transition member 4 through the inner hollow 150 of connector 15, because the transition member syndeton 42 of transition member 4 one end is connected with coating member 5, the other end utilizes seal 81 sealing to be arranged on accessory 8, and accessory 8 and nose adhesive parts 2 are tightly connected, so the air after filtering directly enters nose exocoel 22 through transition member through hole 41, supply human respiratory.

For ensureing the air of human body respiration to high-quality health, nose adhesive parts 2 is also provided with anion generation part 16, this anion generation part 16 comprises release end 161 and Connection Block 162, wherein discharging end 161 can releasing negative oxygen ion, be positioned at nose exocoel 22 inner, Connection Block 162 and nose adhesive parts 2 are tightly connected, and the negative oxygen ion that release end 161 discharges directly enters nose exocoel 22.Release end 161 is arranged at nose exocoel 22 inner, the negative oxygen ion discharged mainly for avoiding negative oxygen ion generation part 16 after filtration diaphragm 101 time hindered, affect the quantity that negative oxygen ion enters nose exocoel 22.
