The working principle is as follows: referring to fig. 1, 2, 3, 4, 5, 6, 7, 8 and 9, by providing the first casing 3 and the second casing 4, since the first casing 3 and the second casing 4 are formed by two hollow semicircles, the first casing 3 and the second casing 4 are suitable for a user to put into a nasal cavity, and the length of the first casing 3 and the second casing 4 is limited, so that the effect of multi-layer filtering of an allergic substance can be achieved.

Through the supporting column 6, before the user puts the first casing 3 and the second casing 4 into the nasal cavity, the supporting column 6 is rotated to move on the surface of the connecting column 5, the first casing 3 and the second casing 4 can be driven to move by extending or shortening the supporting column 6, after the supporting column 6 is moved, one end of the supporting column can enter the first connecting groove 15 to support the first casing 3 and the second casing 4, so that the effect of adjusting the width of the first casing 3 and the second casing 4 can be achieved, after the user adjusts the first casing 3 and the second casing 4 to be suitable for the width of the nasal cavity, the first casing 3 and the second casing 4 are put into the nasal cavity, the first casing 3 and the second casing 4 can generate the expansion tension degree in the nasal cavity of the user, and then the first casing 3 and the second casing 4 can be tightly attached to the nasal cavity to expand the nasal cavity, so that the effect of supporting the nasal cavity of the user by using the first casing 3 and the second casing 4 can be achieved, when the first casing 3 and the second casing 4 are expanded, the first casing 3 and the second casing 4 move to separate a part of the first rotating column 10 from the first rotating groove 8, because the expansion limit of the first casing 3 and the second casing 4 is limited, the first rotating column 10 can not be completely separated from the first rotating groove 8, so that the effect of stabilizing the first rotating column 10 can be achieved, the effect of enabling a patient to breathe smoothly can be achieved through a plurality of breathing holes 13, a user sprays the nasal cavity allergen blocking agent in the filter sleeve 11, the sponge block 12 can absorb part of the blocking agent, and a later user can inhale the nasal cavity allergen blocking agent during breathing, so that the effect of continuously diffusing the nasal cavity allergen blocking agent can be achieved, meanwhile, the sponge block 12 has an adsorption effect, the user drives air to flow during breathing, and the sponge block 12 can temporarily adsorb most of dust in the air, allergenic such as pollen, the patient uses through cooperation sponge piece 12 and breathing hole 13 behind adjusting first cover shell 3 and the second cover shell 4 to can reach the effect of filtering allergens such as dust, through the sponge core 14 that sets up, the user is when breathing, can block granule such as dust or pollen that float in the air through a plurality of sponge cores 14, and then adsorb it, thereby can reach the effect of filtering small-size granule.

Through the latex ring 16 that sets up, because latex ring 16 is natural emulsion can laminate with skin, after the user puts into the nasal cavity with first cover shell 3 and second cover shell 4, latex ring 16 can stay outside the nasal cavity, and then can laminate with skin on every side, compliance through latex ring 16, thereby can reach the effect of the outer skin of protection nasal cavity, the user passes mounting hole 2 through the bottom with first cover shell 3 and second cover shell 4 from connecting block 1, and then pass the inside that fixed orifices 17 put into thread groove 18 with the screw thread post, thereby can reach and fix the effect in mounting hole 2 with first cover shell 3 and second cover shell 4, first cover shell 3 and second cover shell 4 are after fixed simultaneously, thereby can reach the effect that the nasal cavity was put into simultaneously with two first cover shells 3 and second cover shell 4 to the person of facilitating the use.

Through the arranged stop plate 20, a user drives the clamping block 24 to move by moving the stop plate 20, and then the clamping block 24 is placed in the sliding groove 21, then the stop plate 20 is rotated to rotate the clamping block 24 to a position coinciding with the clamping groove 22, and then the stop plate 20 is moved downwards to enable the clamping block 24 to enter the clamping groove 22, so that the effect of fixing the stop plate 20 can be achieved, after the stop plate 20 is installed, the user can breathe without obstacles through the ventilation holes 23, parts in the first casing 3 and the second casing 4 can be blocked through the stop plate 20, when the parts in the first casing 3 and the second casing 4 are prevented from being exposed to the outside and falling, the user cannot search parts falling accidentally, meanwhile, the attractiveness of the first casing 3 and the second casing 4 can be improved, through the arranged extension block 26, when the distance between the first casing 3 and the second casing 4 is short, the inner walls of the first jacket 3 and the second jacket 4 can extrude the lengthened block 26 to enable the extrusion spring 27 to enter the lengthened groove 25, then the lengthened block 26 is clamped into the clamping groove 22 to fix the blocking plate 20, when the first jacket 3 and the second jacket 4 expand, the spring 27 can move the lengthened block 26 out of the lengthened groove 25, the effect of lengthening the clamping block 24 can be achieved, and the blocking plate 20 can be fixed after the first jacket 3 and the second jacket 4 are opened conveniently.

Through the arranged air baffle 28, when a user places a large amount of haze or places with more dust, the first casing 3 and the second casing 4 are placed in the nasal cavity, the air baffle 32 is driven to rotate through the rotation adjusting column 31, the air baffle 32 is rotated to the position below the air passing hole 29 to be shielded, then the surface of the air baffle 28 is provided with two air passing holes 29 for ventilation, so that the effect of limiting the dust from entering the user when the dust breathes more is achieved, meanwhile, the situation that the breathing hole 13 and the sponge core 14 are blocked due to the excessive dust is prevented, through the arranged sucking disc, when the user uses the connecting block 1 to place the two first casing 3 and the second casing 4 into the nasal cavity, the sucking disc is driven to rotate through the rotation limiting block 35, so that the sucking disc is close to the skin near the nose, and then, through the adsorption characteristic of the sucking disc, the effect of stabilizing the connecting block 1, the first casing 3 and the second casing 4 in the nasal cavity can be achieved, the first shell 3 and the second shell 4 are prevented from easily falling out of the nasal cavity when the patient moves.

Through the go-between 41 that sets up, the user is through taking out go-between 41 from the inside of standing groove 40, then through putting go-between 41 inside two first shells 3 make fixed column 42 put into second spread groove 39, and then put into the nasal cavity with first shell 3 and second shell 4, connect two nasal cavities through go-between 41 and then go-between 41 can block on the cartilage in the middle of the nose, because go-between 41 has the compliance can with the skin laminating, thereby can reach the effect that the person of facilitating the use simply connects two first shells 3, convenient to use carries simultaneously.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
