Gauze mask and head-wearing protective equipment

Abstract

The invention relates to the field of protective devices, in particular to a gauze mask and head-wearing protective equipment. The gauze mask comprises a gauze mask base body, and breathing channels used for allowing gas to circulate when a user breathes are formed in the gauze mask base body; the gauze mask further comprises filter layer switching devices and at least two filter layers with the different filter properties, and the filter layer switching devices are installed on the gauze mask base body and used for switching the filter layers located on the breathing channels according to the requirements. When the gauze mask is used, the user can adopts the filter layer switching devices to switch the filter layer with the needed filter property to the breathing channels according to the air filter requirements of the user, and the filter layers filter particulate matter or specific gas in the outside air; when the air quality of the environment where the user is located is changed, the filter layers with the corresponding filter properties can be switched through the filter layer switching devices; due to the fact that the gauze mask can automatically switch the different filter layers, different usage occasions can be met, and the usage convenience of the gauze mask is improved.

Description

technical field [0001] The invention relates to the field of protective equipment, in particular to a mask and head-wearing protective equipment. Background technique [0002] As a common protective product, masks are widely used in daily life and industrial production, such as using medical masks to prevent droplet infection, using anti-dust masks to avoid inhaling dust with particle diameters above 5um, and using N90 or N95 masks to absorb PM2.5 particles in the air, or use a cotton mask to keep your face warm in a cold environment. In order to cope with different use environments, users need to prepare multiple masks of different types, and need to switch masks when the use occasion changes, which is inconvenient to carry and use. A mask with switchable filter elements in the prior art can switch different types of filter elements according to different use environments to achieve the corresponding protective effect, but it still needs to carry multiple filter elements a...
