Problems solved by technology
If you want to achieve high dust suppression efficiency, the only way is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel a lot of breathing resistance, and at the same time increase the quality of the mask, making it uncomfortable to wear for a long time

Embodiment Construction
[0019] The filter dustproof mask with a built-in fan includes a filter part, an air inlet part, and a mask shell part. After the fan 7 is activated through the touch button on the main board 9, the flow of the wind will be accelerated, and the gas sucked by the fan 7 will pass through the air inlet grille 3 , the clean air filtered by the high-grade electrostatic fiber filter material and activated carbon layer 11 is blown into the mask shell 1, and at the same time, the air intake check valve 5 is opened and enters the mask shell 1, and enters the human body through the respiratory organ. During the gas, the air outlet one-way valve sheet 5 on both sides of the mask shell is opened, and the gas is discharged from the mask shell 1.

The invention discloses a built-in breather valve and an air filtering mask of a fan. The built-in breather valve and the air filtering mask of the fan are characterized in that a built-in filter screen is made of high-class static fiber filter material matched with activated carbon and effectively prevents dust, various gases and oily particles from being involved therein, especially the air inlet volume of the built-in fan is increased, the problem of wind resistance of a filtering device is effectively solved, the air flowing speed in the mask is improved, and breathing pressure of a human body is reduced. An inspiration one-way valve piece can prevent powerful wind from being straightly blown towards the face of the human body and enables inflowing wind to be soft. The inspiration one-way valve piece can exhaust waste gas, and outside pollutants is prevented from entering the valve while stuffiness feeling in the mask is relieved.
Description
【Technical field】 [0001] The invention is a mask based on improving the dry and clean air flow in the mask through a built-in fan, so that the human body can breathe more smoothly and be more willing to wear it. 【Background technique】 [0002] With the increasingly close social activities and the continuous development of the economy, people's lives are becoming more and more happy. At the same time, the air pollution caused by natural and human factors such as industrial production, automobile exhaust, forest fires, and volcanic eruptions is becoming more and more serious, and the concentration of harmful substances in the atmosphere is getting higher and higher. High, the harm to the human body is becoming more and more serious, resulting in a large number of smog weather, especially in North China. At the same time, as the main way for various germs to spread, the infected body passes through the respiratory tract, and the pathogens are discharged by sneezing, coughing, e...
