Abstract
The utility model relates to a nasal cavity filter which is composed of a filtering cavity and a clamping device, wherein, the filtering cavity is a pair of grid-surface ventilation cones in the similar shape of a naris; the clamping device is used for clamping and fixing the filter on a nose. The utility model is suitable for all the people to wear; the utility model can play the role of air filtration and prevent pollutants in the air from entering a breathing system of a human body.
Description
Technical field:
The utility model asal filter relates to a kind of air filter that prevents breathing problem, belongs to the medical health care field.
Background technology:
In the work life, particularly in serious pollution environment, people enter human respiratory in order to reduce pollutant, often be to wear mouth mask to prevent breathing problem, yet easily cause air-breathing not smooth owing to wear mouth mask, and influence attractive in appearancely, and and be not suitable for using in season of sweltering heat and area, have certain inflexible sex-limited.
Summary of the invention:
The utility model purpose is to avoid the deficiencies in the prior art part, provides a kind of simple in structure, the asal filter of good filtration effect, and it has overcome the inflexible sex-limited of area and use in season.
The utility model is realized by following measure, it is formed by filtering cavity and clamping device, filtering cavity is a pair of grid surface ventilative cone similar to nostril form, the bottom of cone is the plane or is arc surface, the grid surface lid of breathing freely is arranged at the top of cone, clamping device is positioned at the end of two cones, work to connect and clamp two cones, clamping device one end is connected in the end of one of them cone of filter, and the other end is connected in the end of filter another one cone.
Filter is made of metal material or plastic material, the utility model will filter dictyosome and make the bottom and be plane or be the cone of arc surface, and under the prerequisite that guarantees filter effect, one side is complied with the nostril structure, increase comfort, can guarantee air-breathing unimpeded on the other hand again.
The inner surface of the utility model cone posts the film that has pore, and film can immerse liquid medicine and rise moistening or therapeutic action.
The utility model filters also can pack in the cavity medicinal powder or pill, plays health care or therapeutic action.
The utility model clamping device is a fixture of the spring, and spring one end is connected in the end of one of them cone of filter, and the other end of spring is connected in the end of filter another one cone.
The utility model asal filter can be made of elastomeric material, and this moment filters cavity and clamping device is made one, leans on the elasticity of material itself that asal filter is fixed in the nostril.
The utility model provides a kind of novel nasal cavity filter, and it has simple in structure, the characteristics of good filtration effect, and also it is not subjected to the region. and season limit has certain practicality.
Description of drawings:
Accompanying drawing 2 is another example structure schematic diagrames of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment:
The utility model is formed by filtering cavity 1 and clamping device 2 as shown in Figure 1, filtering dictyosome is a pair of grid surface ventilative cone similar to nostril form, the bottom of cone is the plane or is arc surface, the grid surface lid 3 of breathing freely is arranged at the top of cone, the inner surface of circular cone posts the film 4 that has pore, film can immerse liquid medicine, two conical ends, clamping device position, clamping device is a fixture of the spring, spring one end is connected in the end of one of them cone of filter, the other end of spring is connected in the end of filter another one cone, filters can pack in the cavity medicinal powder or pill.
The utility model is formed by filtering cavity 1 and clamping device 2 as shown in Figure 2, filtering dictyosome is a pair of grid surface ventilative cone similar to nostril form, the bottom of cone is the plane or is arc surface, the grid surface lid 3 of breathing freely is arranged at the top of cone, the inner surface of circular cone posts the film that has pore, film can immerse liquid medicine, filter to pack in the cavity medicinal powder or pill, asal filter is made of elastomeric material, this moment filters cavity and clamping device is made one, and clamping device works to connect two cones, and filter is fixed in the nostril by the elasticity of material itself.
