Inner ventilation type large ventilating section anti-haze mask

Abstract

The invention relates to the technical field of anti-haze appliances and discloses an inner ventilation type large ventilating section anti-haze mask. The anti-haze mask comprises a breathing mask main body, a first air filter module and a second air filter module, wherein a breathing cavity is formed in the breathing mask main body; the air outlet of the first air filter module is communicated with the air inlet of a left-side inhalation channel through a first hose; the air outlet of the second air filter module is communicated with the air inlet of a right-side inhalation channel through a second hose; the air outlet of the left-side inhalation channel and the air outlet of the right-side inhalation channel are respectively communicated with the breathing cavity through a one-way inhalation valve; and an exhalation channel is communicated with the breathing cavity through a one-way exhalation valve. The anti-haze mask disclosed by the invention is reasonable and compact in structure, the air is filtered by a special module, the first air filter module and the second air filter module are respectively attached to the cheeks of a human body, and the anti-haze mask is comfortable to wear, greatly increased in ventilating section, high in air filtration capacity, low in breathing resistance and suitable to be worn outdoors for a long time and has the characteristics of safety, labor conservation, simplicity and high efficiency.

Description

technical field [0001] The invention relates to the technical field of anti-haze products, and relates to an anti-haze mask with an internal 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...
