## Title
Filtering assembly in nasal cavities

## Abstract

A filtering assembly in nasal cavities includes a connector with two rings connected by a link, and two filtering members are securely connected to the two rings. The two filtering members are inserted into the wearer's nasal cavities so as to effectively filter foreign objects from entering to the wearer's lungs.

## Background
FIELD OF THE INVENTION
The present invention relates to a filtering assembly including two filtering members connected to a connector and the filtering members are inserted into a user's nasal cavities.
BACKGROUND OF THE INVENTION
There are many people suffered by different kinds of pollution in this modern world and the pollutions cause several problems to our noses such as allergic rhinitis and sinusitis. The sources of pollution come from two main sources, one of which is from industry factories, such as carbon monoxide, cyanogens compound particles and heavy metal particles. The other main source is from transportation system, such as air-crafts, vehicles, motorcycles or ships. The pollutions are in forms of tiny particles spread in the air and enter into people's bodies from noses. Although there are nose hairs in our noses to filter foreign objects, the tiny particles are so many and so tiny that they cannot be effectively filtered just by the nose hairs in noses. In order to prevent the tiny particles of pollutions from entering our noses, some people wear masks which cover the nose and mouth. However, most of the masks are made by fabrics which includes orifices between fibers and these orifices are too big for the tiny particles so that the wearers still inhale these tiny particles via noses. Besides, the masks cannot perfectly match the contour of the wearers′ face and gaps are formed between the face and the masks and these tiny particles are easily inhaled into the wearers′ lungs.
The present invention intends to provide a filtering assembly which includes a connector with two rings and two filtering members are connected to the two rings. The filtering members can be inserted into the nasal cavities so as to effectively filter the foreign particles.
SUMMARY OF THE INVENTION
The present invention relates to a filtering assembly in nasal cavities and comprises a connector having two rings connected by a link, and two filtering members connected to the two rings. The two filtering members are inserted into the wearer's nasal cavities.
The primary object of the present invention is to provide a filtering assembly that can be directly inserted in the nasal cavities.
Another object of the present invention is to provide a filtering assembly that is easily to be manufactured at low cost.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 to 3, the filtering assembly of the present invention comprises a connector 1 which includes two rings 11 connected by a link 12. The link 12 is a curved link and can be made by plastic material. Two filtering members 2 are securely connected to the two rings 11. The two filtering members 2 are directly inserted into the nasal cavities of the wearer to filter foreign objects such as the tiny particles of pollutions from entering into the wearer's lungs. The filtering members 2 are secured to the rings 11 by way of heat fusion, gluing or any known methods.
FIGS. 4 and 5 show another embodiment of the filtering members 2 wherein the two filtering members 2 each have a flange 21 extending outward from an end thereof and the flanges 21 are secured to two respective top surfaces of the rings 11.
FIGS. 6 to 8 show another embodiment of the filtering assembly wherein each of the rings 11 includes an engaging slot 111 defined in a top surface thereof and each of the engaging slots 111 includes a narrow opening and a wide bottom. The two filtering members 2 each have a flange 21 extending outward from an end thereof. Two pressing members 3 are used to press the two flanges 21 into the engaging slots 111 of the two rings 11. Each pressing members 3 has an insertion 31 so that the insertions 31 press the flanges 21 into the engaging slots 111. The insertions 31 are shaped to be complementary to the engaging slots 111 and can be securely engaged with the engaging slots 111 to position the filtering members 2 to the rings 11. Each of the pressing members 3 is a collar and two bars crossly connected with each other are connected in each of the collars. By the two bars, the pressing members 3 press the top surfaces of the two filtering members 2 and this is helpful to position the filtering members 2 in stable status.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
