Trapezoid mask with breath focusing function and selective filtrating function

Abstract

The invention provides a trapezoid mask with a breath focusing function and a selective filtrating function. The trapezoid mask comprises a mask surface and a filtering body, wherein the mask surface is of a narrow-end-up trapezoid shape and is capable of being combined and detached, and the filtering body has the breath focusing function and the selective filtrating function, for short the mask surface and the filtering body. According to the trapezoid mask with the breath focusing function and the selective filtrating function, the mask surface which is of the narrow-end-up trapezoid shape and is capable of being combined and detached is adopted, so that the trapezoid mask is more suitable for the narrow-end-up shape of the nasal cavity and oral cavity of a human face. The trapezoid mask with the breath focusing function and the selective filtrating function has the advantage that the design that the filtering body can focus breaths and use a series of filter layer sheets selectively to filter off PM2.5 and other pollutants in varying degrees in air enables healthy and clean air to be provided for the human body. The area of the trapezoid mask is half the size of an existing mask with the largest area, and the trapezoid mask is convenient to wash, thereby saving water resources and washing products.

Description

[0001] technical field [0002] The invention relates to a mask, in particular to a trapezoidal mask with selective filtering for focused breathing. Background technique [0003] Most of the existing masks do not protect against PM2.5 in the air, or the breathing air is obstructed and enters and exits from the eyes along the nasolabial folds, and strips of pollutants appear continuously. Frequent cleaning will cause waste of water resources and washing products . In cold areas in winter, the temperature and humidity of the gas that the human body breathes is high, and the gas is impacted by the cold air, forming a freezing point of the gas, which falls to the lens of the wearer along the nasolabial fold, causing blurred vision and affecting walking, cycling and other sports. In order to cope with the emergence of smog weather, masks such as 3m9001A and 8210N95 have been selected, but their airtightness is tight and their air permeability is poor, so they will feel short of ...

Problems solved by technology

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, the breathing filter points are not concentrated, and the filtering performance is not selective, which affects the human facial image and interpersonal relationship.
