Problems solved by technology
The sanitation workers working on the road can use masks to prevent the inhalation of dust, but the traffic police who direct traffic at intersections cannot use them. Firstly, it is inconvenient to direct traffic, and secondly, the image is not good.
[0003] For long-term outdoor workers, summer is also the saddest, because the mask has a large area, and the face below the eyes will be very hot. It also needs to be fixed with two ropes through the ears. The ropes are loose and not tight. Well, if you tighten it for a long time, your ears will hurt

Embodiment Construction
[0014] Combine below figure 1 Specifically illustrate the embodiment 1 of the invisible embedded nasal dust filter 1 of the present invention, as figure 1 As shown, the nasal dust filter 1 inserts the filter body 11 into the nostril from the bottom of the nose 2. Specifically, the filter 1 includes a strip-shaped bracket 10, and the two ends of the bracket are provided with the filter body 11 embedded in the nostril. The filter body 11 is a cylinder, and the top of the cylinder is in the shape of a spherical crown. Of course, the filter body 11 can also be set in the shape of a truncated cone. Filter body can select the non-woven fabric that mouth mask is used to make for use.
[0015] Combine below figure 2 Embodiment 2 of the invisible embedded nasal dust filter of the present invention is specifically described. On the basis of Embodiment 1, the filter body 11 includes a non-woven outer layer and activated carbon wrapped in the middle of the non-woven outer layer. Has ...

The invention discloses an invisible embedded type dust filter for the nose. The invisible embedded type dust filter for the nose comprises a bar-shaped support frame. Two ends of the support frame are provided with filtering bodies for being embedded into the nostrils. The filtering bodies comprise non-woven fabric outer layers and activated carbon coated in the middles of the non-woven fabric outer layers. The lower end of the support frame is connected with an arc-shaped supporting frame for supporting the filtering bodies at the two ends of the support frame. The support frame and the support frame are all of elastic transparent plastic structures. According to the invisible embedded type dust filter for the nose, the filtering bodies for being embedded into the nostrils are arranged at the two ends of the support frame, the filtering bodies are put into the nostrils and closely attached to the inner walls of the nostrils. Dust can be prevented from being absorbed into the nose, and filters are added into the nostrils equivalently. The two filtering bodies are connected with the support frame of the elastic transparent plastic structure in between, the structure is reliable, fall-off is not prone to happen, and aesthetics is not affected. Thus the invisible embedded type dust filter for the nose has the advantages of being compact in structure, convenient to use, safe and reliable.
Description
technical field [0001] The present invention relates to nasal dust filters. Background technique [0002] Long-term outdoor workers, such as traffic police, often need to use whistles to direct traffic when working at intersections. Some people vividly call traffic police "vacuum cleaners" on the road. Sanitation workers working on the roads can use masks to prevent the inhalation of dust, but traffic policemen at intersections directing traffic cannot use them. [0003] For long-term outdoor workers, summer is also the saddest, because the mask has a large area, and the face below the eyes will be very hot. It also needs to be fixed with two ropes through the ears. The ropes are loose and not tight. Well, if you tighten it for a long time, your ears will hurt. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an invisible embedded nasal dust filter, which is simple in structure, easy to wear and comfortable to u...
