The utility model comprises the following steps:
the utility model aims to provide a breathing filter which is simple in structure, suitable for being worn for a long time and comfortable to wear and is arranged in a nasal cavity.
The utility model is implemented by the following technical scheme: the patent aims to provide a breathing filter internally arranged in a nasal cavity, which comprises an arc-shaped frame with an opening at the top, wherein the inner surface of the frame is provided with vent holes, and each vent hole is respectively provided with a nose plug with a through hole at the center; a dust filter element is movably inserted into the frame, and a plurality of holes are formed in the outer surface of the frame; the top cover of the frame is provided with a cover body.
Further, a fixing ring is fixed at the vent hole, an annular boss is arranged at one end of the fixing ring away from the vent hole, and one end of the nose plug is sleeved on the annular boss.
Furthermore, the nasal obstruction is made of medical silica gel or medical rubber.
Further, the dust filter element sequentially comprises a polyvinyl acetal sponge of a first filter layer, an active carbon filter layer of a second filter layer and a nonwoven layer of a third filter layer, wherein the nonwoven layer contains a nano silver ion degerming agent; the third filter layer is in contact with a side surface of the frame provided with the vent hole.
Further, a soft silica gel layer is fixedly coated on the side surface of the frame, on which the vent holes are formed.
Further, elastic fixing straps are arranged on the frame, and two ends of each fixing strap are respectively fixed at two ends of the frame.
The utility model has the advantages that: the nose plug is simple in structure and easy to realize, can adapt to the nose shape by plugging the nose plug into the nostril, is suitable for being worn for a long time, is comfortable to wear, and avoids squeezing the face.
Description of the drawings:
in order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic diagram of the overall structure of the present utility model.
Fig. 2 is a schematic diagram of the connection structure of the frame and the dust filter cartridge.
Fig. 3 is a schematic structural view of the frame.
The dust filter comprises a frame 1, holes 11, vent holes 12, a nose plug 2, a fixing ring 3, an annular boss 4, a dust filter element 5, a first filter layer 51, a second filter layer 52, a third filter layer 53, a cover 6, a soft silica gel layer 7 and a fixing strap 8.
The specific embodiment is as follows:
as shown in fig. 1-3, the purpose of this patent is to provide a breathing filter with a built-in nasal cavity, which comprises a frame 1 with an arc shape and an opening at the top, wherein the inner surface of the frame 1 is provided with vent holes 12, each vent hole 12 is respectively provided with a nasal plug 2 with a through hole at the center, and the nasal plugs 2 have different models so as to adapt to the nostrils of users with different forms; a fixed ring 3 is fixed at the vent hole 12, an annular boss 4 is arranged at one end of the fixed ring 3 far away from the vent hole 12, one end of the nose plug 2 is sleeved on the annular boss 4, and the nose plug 2 is made of medical silica gel or medical rubber; a dust filter element 5 is movably inserted in the frame 1, and a plurality of holes 11 are formed outside the frame 1; the top cover of the frame 1 is provided with a cover body 6, which is convenient for replacing the dust filtering filter element 5 in the frame 1.
