Protective respirator

Abstract

The invention discloses a protective respirator. The respirator comprises a base, multiple horizontal reinforcing ribs and multiple vertical reinforcing ribs are arranged on the base, and air holes are formed between two adjacent horizontal reinforcing ribs and two adjacent vertical reinforcing ribs; a silicone pad is arranged on one side of the base, a decoration cover is arranged on the other side of the base in a clamping mode, multiple intake holes are formed in the decoration cover, and a filter element is arranged between the decoration cover and the base; elastic ear bands are arranged on two sides of the base. The elastic deformation of the silicone pad is used for adapting to the surface profile of the face of a wearer, the leakproofness with the face is improved, the problem of air leakage is avoided, and thus the filter effect is effectively guaranteed; the own characteristic of the nano filter screen filter element and the guaranteed filter effect lay a good foundation for long wearing and sport wearing; meanwhile, each component in the protective respirator has no complex connection structure, and the respirator is convenient to disassemble and assemble and replace components, and small in size and weight, good in permeability, attractive in appearance and long in service life.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a respiratory protective mask. Background technique [0002] Air pollution, such as smog, carries high concentrations of particulate matter (PM), including heavy metals, toxic chemicals and compounds, bacteria and viruses. These pollutants often come from industrial activities, burning coal, vehicle exhaust, and other sources of pollution. Particles are the deadliest form of air pollution because of their ability to penetrate deep into the lungs and bloodstream, causing permanent DNA mutations, heart attack, respiratory disease, cancer and premature death if they are not filtered from the breath ( Studies have shown that these diseases are related to breathing polluted air). [0003] In general, these situations can be avoided with personal respiratory protection equipment, including face masks and nasal filters. However, most masks on the market are not designed for filtering a...

AI Technical Summary

Problems solved by technology

Since these masks are difficult to seal in actual use, contaminated air leaks into the mask through the gap between the mask and the user's face, greatly reducing the filtering effect, which is the main disadvantage of this type of respiratory protection device

[0004] At the same time, this type of respiratory protection device has the following defects: poor breathing experience, not suitable for long-term wear, and not suitable for wearing during exercise. These problems come from the large air resistance of the filter itself; in addition, the appearance of this type of respiratory protection device Bloated, poor air permeability and aesthetics greatly limit their daily use and promotion
