However, in the design of the mask, in order to achieve a good filtering effect, the pore size of the selected filter material is relatively small, which will have a certain resistance to the entry of air, so it will cause the wearer to inhale and exhale. It takes a certain amount of effort, and it is easy for the wearer to feel Shortness of breath, a feeling of suffocation, and severe cases can lead to hypoxia and shock

Abstract
The invention relates to a ventilating type mask and a using method, and belongs to the field of daily life. The mask comprises a mouth-nose protective cover main body, and further comprises a volume-variable gas storage bag and a power air feeding device, wherein the gas storage bag is fixedly arranged on the mouth-nose protective cover main body; an air inlet and an air outlet are formed in thegas storage bag; the air inlet is formed outside the mouth-nose protective cover main body; the air outlet is formed inside the mouth-nose protective cover main body; the air inlet is detachably connected to the power air feeding device; and the power air feeding device comprises a filter material part, a fan with blades, a rotary motor, a battery and a control part, which are sequentially connected.
Description
technical field [0001] The disclosure belongs to the field of daily life, and in particular relates to a ventilating mask and a use method thereof. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Both theory and practice have shown that for infectious diseases transmitted by droplets, wearing a mask is an effective way to physically isolate pathogens. According to the size and harm of pathogen particles, different levels of medical masks with a filtration efficiency of 95% or more than 99% are also produced. Protective masks, surgical masks, general medical masks, etc. At the same time, masks are also one of the effective means of protection for pathogenic aerosols related to biosafety produced by special activities such as laboratories, or natural aerosols such as tuberculosis that spread through the air. Smog can contain chemical substances su...
