External ventilation type haze-proof mask with large ventilation section

Abstract

The invention relates to the technical field of haze-proof articles and provides an external ventilation type haze-proof mask with a large ventilation section. The external ventilation type haze-proof mask comprises a breathing mask main body, a first air filtering module and a second air filtering module, wherein the breathing mask main body is provided with a breathing cavity; an air outlet of the first air filtering module is communicated with an air inlet of a left inhaling channel through a first hose; the air outlet of the second air filtering module is communicated with the air inlet of a right inhaling channel through a second hose; the air outlet of the left inhaling channel and the air outlet of the right inhaling channel are communicated with the breathing cavity through inhaling check valves respectively; and an exhaling channel is communicated with the breathing cavity through an exhaling check valve. The external ventilation type haze-proof mask with a large ventilation section is reasonable and compact in structure; the special modules are used for filtering air; the first air filtering module and the second air filtering module are fitted to cheek parts of a human body respectively; the external ventilation type haze-proof mask is comfort to wear, the ventilation section is greatly enlarged, the air filtering quantity is large and the breathing resistance is small; and the external ventilation type haze-proof mask is suitable for wearing outdoors for long time, and has the characteristics of safety, labor saving, simplicity and convenience and high efficiency.

Description

technical field [0001] The invention relates to the technical field of anti-smog products, and relates to an anti-smog mask with an external ventilation type and a large ventilation section. Background technique [0002] In northern China, industrial waste gas emissions, vehicle exhaust emissions, and boiler exhaust emissions have caused urban air pollution. The accumulation of pollutants in a windless environment makes the air quality poor and forms haze weather. In order to reduce the impact of air pollution on the human body Many citizens choose to wear anti-haze masks when traveling. Common masks include disposable medical masks and anti-virus masks. These two kinds of masks have the following problems in the use process: disposable medical masks are relatively thin, and they are not compatible with the human face. The various parts are not tightly fitted, and there is a risk of side leakage. In addition, disposable medical masks are made of three to four layers of non-w...
