Abstract
The utility model relates to an environment-protective appliance, which is developed to solve the pollution residual in a filter core. The utility model discloses a nose plug, which is a coniform filter core. The filter core is divided into an upper part and a below part. The upper part is cone cover and the below part is a cone; a filter piece is positioned between the bottom surface of the cone cover and the small end face of the cone, which can make the hole in the filter core not connective; the structure enhances the filtering performance. Put the nose plug into the nares that will make the function for filtering air. The device can be used for every season.
Description
Technical field
The utility model relates to the environmental protection articles for use, specifically belongs to the nasal obstruction that filtered air is used.
Background technology
When air polluted or air in when spreading disease germs, people can put on mouth mask habitually, avoid air pollution, prevent the germ invasion and attack.Yet in the summer of sweltering heat, it is very uncomfortable to mask one's nose and mouth with a cloth, and for addressing this problem, Chinese patent notification number CN2441500Y discloses the patent that a kind of name is called " nasal obstruction ".It is a cone filter core, and a plurality of holes are arranged in the filter core.Airborne pollution is when the hole, because the hole of each row directly communicates, though the airborne pollution of part by the hole occlusion in the filter core, but has the airborne pollution of part to flow directly into nasal cavity easily.
Summary of the invention
For solving filter core occlusion pollution problem, the utility model provides a kind of nasal obstruction, its occlusion pollution effectively.
The utility model is to realize by following technical scheme, it is made up of the hole in filter core, the filter core, its structural feature is that this filter core divides upper and lower two parts to constitute, top is one and is conical cap, the bottom is a cone, conical cap and cone match and are integral, and are provided with filter between conical cap inner bottom surface and cone small end face.
The utility model is simple in structure, owing to adopt filter, the hole in the filter core is not directly communicated mutually, has improved strainability, and has been applicable to the four seasons.
Description of drawings
The utility model is described in further detail below with reference to drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another embodiment of the present utility model.
The specific embodiment
Among Fig. 1, nasal obstruction is a pyramid type filter core, and the material of present embodiment nasal obstruction is nontoxic sponge.The pyramid type filter core divides upper and lower two parts to form, and top is conical cap 4 and lower cone body 1, and cone is placed in the conical cap, rely on the elasticity of material, make two parts cover integrator, filter 3 is put on the inner bottom surface of conical cap 4 in advance, and inclined hole 2 in straight hole in the conical cap 5 and the cone is separated.When air entered nasal obstruction, airborne pollution was by inclined hole in the filter core and filter occlusion, and clean air enters nasal cavity from the filter core straight hole.
Among Fig. 2, the hole that filter core lists is a straight hole 5, has only by after filter 3 occlusions, and clean air enters nasal cavity from the filter core straight hole.Follow the prescribed rules, the hole that filter core lists can all be an inclined hole also.
Claims (1)
1. nasal obstruction, formed by the hole in filter core, the filter core, it is characterized in that this filter core is divided into upper and lower two parts and constitutes, top is one and is conical cap, the bottom is a cone, conical cap and cone match and are integral, and are provided with filter between conical cap inner bottom surface and cone small end face.
