Double-fan breathing mask and implementation method thereof

Abstract

The invention discloses a double-fan breathing mask and an implementation method thereof. The breathing mask comprises a mask body; the mask body forms an after-filtration space at the mouse and noseposition of a user, wherein the mask body is also provided with an air charging passage and an air discharging passage; the air charging passage and the air discharging passage are used for filteringair and communicating with the after-filtration space and external air; an air charging fan is arranged inside the air charging passage and is used for driving air flow to flow into the after-filtration space after the air flow is filtered; and an air discharging fan is arranged inside the air discharging passage and is used for driving the air flow to flow out of the after-filtration space. The double-fan breathing mask and the implementation method thereof can form stable air pressure inside the mask by arranging an air inlet fan and an air outlet fan on the mask so that a wearer can breathewithout being affected by the air pressure and can breathe more smoothly after wearing the double-fan breathing mask, so the double-fan breathing mask is safe and healthy.

Description

technical field [0001] The invention relates to a breathing mask and a realization method thereof, in particular to a double-fan breathing mask and a realization method thereof for convenient breathing. Background technique [0002] The current common protective measures are generally the way of wearing masks, especially for some pollutants with a particle size above PM2.5, usually wearing masks with corresponding protection levels for protection. [0003] Current anti-smog masks usually use filter materials. However, due to the very small particle size of smog, for example, the particle size of PM2.5 is less than or equal to 2.5 microns in diameter. In order to filter such small pollutant particles Therefore, the filtration capacity of the filter material needs to be relatively high, and the result of the high filtration capacity of the filter material will lead to a decrease in the air permeability of the filter material, so the wearer usually feels that the resistance to ...

Problems solved by technology

[0003] Current anti-smog masks usually use filter materials. However, due to the very small particle size of smog, for example, the particle size of PM2.5 is less than or equal to 2.5 microns in diameter. In order to filter such small pollutant particles , the filter capacity of the filter material needs to be relatively high, and the result of the high filter capacity of the filter material will lead to a decrease in the air permeability of the filter material, so the wearer usually feels that the resistance to breathing is relatively large, and it is difficult to breathe.

[0004] Ordinary masks generally filter passively through the user's breathing, that is, the user's own breathing force is required to drive the air through the filter material, which will make the user feel difficult to breathe, and long-term wearing may easily cause the body to be in hypoxia. Working in the state will increase the burden on various organs of the body. For some users with poor physique, such as the elderly and children, it may even cause dizziness and have to stop using it.

[0005] In addition, masks also have the characteristics of covering one's own face. In social occasions, whether it is for the user or the surrounding onlookers, wearing a mask is often considered to be of a bad nature, which hinders the user's habit of daily wearing, unless the smog is severe To the point of being extremely powerful, few people are willing to wear it often

[0006] In the prior art, there has also been an improvement in the mask technology that actively supplies air to provide air filtration, but it is limited by the space and structure of the existing mask. Usually, it is only possible to increase air (intake) into the mask by adding a fan, and the air output is still passive. However, since the human breathing action is a periodic rhythmic action of exhaling and exhaling, the one-way input air will increase the air resistance when the user exhales, which still cannot solve the wearing comfort. , long-term wearing will also cause damage to the user's lung function
