Problems solved by technology

If it is stuffed into the nostrils, it will come into contact with the mucous membrane in the nose. Long-term wearing will damage the nasal cavity, and the filtered dust may come into contact with the nasal cavity, which brings safety hazards to the wearer's health.
[0004] The other is the external nasal type. The current external nasal type can avoid the shortcomings of masks and intranasal breathing filters, but the use of ordinary filter materials is not effective in filtering small molecules such as toxic and harmful substances, and it is not reusable.
[0005] Whether it is an intranasal or an external nasal breathing filter, it only plays the role of respiratory filtration. When the wearer needs special needs, such as refreshing, fragrance, etc., neither the intranasal nor the external nasal breathing filter can meet

Abstract

The invention relates to a functional type external nasal respiratory filter. The functional type external nasal respiratory filter comprises a nasal rack, the front of the nasal rack is provided with a nasal splint, the back of the nasal rack is provided with a filter tube, and the front end of the filter tube is detachably connected with a filter element cover; at least one layer of filter element is mounted inside the filter tube; both sides of the nasal rack are provided with drop guide-in units, and the front end of the drop guide-in units is provided with a drop plug; drops can flow inside the filter tube via the drop guide-in units to soak the filter element so that the filter element can emit smell. The functional type external nasal respiratory filter is convenient to wear and use; the filter element can be changed as required and added with appropriate fragrances as required to achieve refreshing and flavoring functions and the like, so that the functional type external nasal respiratory filter is applicable to various occasions; meanwhile, after the filter element loses efficacy, the functional type external nasal respiratory filter does not need to be integrally replaced, thereby being low in use cost.

Description

technical field [0001] The invention relates to the field of breathing filter equipment, in particular to a functional nasal external breathing filter. Background technique [0002] With the progress of society and the improvement of living standards, the sources of pollution around people continue to increase, such as the increase in vehicles, factory waste, waste, etc., and the air quality continues to decline. Words such as smog, low visibility, and poor air quality frequently appear in people's sights, so masks have become one of the necessities for people to travel. Masks can block some air pollution particles and play a certain role in protecting the health of the wearer. However, wearing a mask in summer often makes people feel uncomfortable, such as dyspnea and suffocation. Fogging causes inconvenience. Therefore, there is a need for a portable and effective breathing filter device that can meet the needs of filtering polluted air without causing discomfort to the ...
