Respirator and active air supplying type breathing protective device with respirator

Abstract

The invention discloses a respirator and an active air supply type breathing protective device with the respirator. The respirator is matched with a mouth and a nose, and a breathing cavity is formedin the inner side of the respirator. The respirator is further provided with an air supplying channel and an air inlet fan located in the air supplying channel. An air supplying opening of the air supplying channel communicates with the breathing cavity. The air supplying opening is located above the mouth and the nose of a user when the user wears the respirator. An air inlet of the air supplyingchannel communicates with the outside through a filtering net covering the outer side of the air supplying channel. The respirator further includes an air exhausting opening. The air exhausting opening is located below the mouth and the nose of the user when the user wears the respirator. The active air supplying type breathing protective device is small in occupied three-dimensional space and beautiful in appearance and can be accepted by the public; by arranging the filtering net externally, not only is daily replacing of the filtering net convenient, but also the use area of the filteringnet is effectively increased; and exhaust gas circulation is avoided through the excellent airflow channel and follow-up design of air flow, and the utilization rate of airflow is improved.

Description

technical field [0001] The invention relates to a daily protection device, in particular to a breathing mask and an active air-supply type breathing protection device with the same. Background technique [0002] In the atmospheric environment with serious automobile exhaust emissions and frequent smog weather, people usually choose to wear self-priming filtering respiratory protective devices (such as disposable masks) in order to avoid the harm of polluted air during daily travel. Considering self-priming In order to ensure that the user can breathe more smoothly, the manufacturer often designs the self-priming filter respiratory protection device with a relatively rough effect, which affects its filtering effect; moreover, the user produces water vapor when exhaling. It is often attached to the cover body, which affects its filtering effect and reduces the user experience. In order to solve the above problems, the active air-supply breathing filter is gradually used in the...
