Filter with breath focusing function and mask

Abstract

The invention provides a filter with a breath focusing function. The filter with the breath focusing function comprises a filter body, wherein two airflow channels corresponding to the nares of a human body respectively are formed in the filter body. When the filter with the breath focusing function is worn on the face of the human body, the two airflow channels are both in the vertical direction and are communicated with the two nares respectively so as to converge breathing gas of the nares; filtering elements used for filtering air are arranged in the lower ends of the two airflow channels respectively; a matched area matched with the lower end of the nose of the human body in shape is arranged on the filter body, and openings in the upper ends of the two airflow channels are located in the matched area; when the filter with the breath focusing function is worn on the face of the human body, the matched area makes contact with the lower end of the nose of the human body in a matched mode. The invention further provides a mask with the breath focusing function.

Description

technical field [0001] The invention relates to the technical field of human breathing filtration, in particular to a filter body with a focused breathing function, and also to a mask with a focused breathing function. Background technique [0002] Masks are common human respiratory filter components. However, most masks have extremely low barrier efficiency to respirable dust below 2.5 microns. In addition, most existing masks have obstructed breathing air when worn, and then pass in and out from the eyes along the nasolabial folds. There are strips of pollutants, which need to be cleaned frequently, resulting in waste of water resources and washing products. In cold areas in winter, the hot and humid air exhaled by the human body reaches the lens of the wearer along the nasolabial fold, causing blurred vision and affecting walking and cycling. In order to cope with the emergence of smog weather, 3m9001A, 8210N95 and other masks have been selected, but their airtightness ...

Problems solved by technology

In order to cope with the emergence of smog weather, 3m9001A, 8210N95 and other masks have been selected, but their airtightness is tight, the air permeability is poor, and there will be a feeling of poor breathing. It is not suitable for children, students, the elderly and people with respiratory diseases. use

It is unscientific for some people to choose invisible filters embedded in the nasal columella due to work restrictions

Because the invisible filter is put into the nostrils, the pollutants will inevitably gather inside and outside the nostrils. In addition, it is often inserted and pulled out, and it is easy to cause infection during touching, causing a series of rhinitis and other diseases.

At present, the thickness of various styles of masks is getting more and more convex, and the area is getting bigger and bigger. Some of them cover all the parts below the eyes, and the breathing filter points are not concentrated, which affects the human facial image and interpersonal language communication.
