Furthermore, the auxiliary mechanism of breathing in still include the barometer of setting in dust mask body inboard and respectively with the controller of barometer, fan electricity connection. In order to further improve intelligent level, through the inboard atmospheric pressure of barometer real-time supervision dust mask body, when the person of wearing breathes in, the inboard atmospheric pressure of dust mask body can reduce, and the barometer detects the signal and feeds back to the controller this moment, by controller regulation fan rotational speed, provides clean air for the person of wearing.
Further, the controller is a PLC controller.
When the utility model is applied in practice, when a wearer exhales, the exhaled air acts on the exhalation mechanism, so that the exhalation mechanism acts and is communicated with the inner side and the outer side of the dustproof mask body, and the exhaled air of the wearer can be rapidly exhausted; when the person of wearing breathes in, the auxiliary mechanism that breathes in provides power, and it is inboard to make the air in the dust mask body outside pass the dust mask body fast and enter into the dust mask body, and then can provide clean air fast for the person of wearing.
Compared with the prior art, the utility model has the characteristics of it is following:
1) the dustproof mask body can improve the filtering and dustproof effects and provide clean air for a wearer, and the breathing action of the wearer is matched through the expiration mechanism and the inspiration auxiliary mechanism to quickly exhaust gas exhaled by the wearer or quickly provide clean air for the wearer, so that high-efficiency filtering and low breathing resistance are realized, an effective filtering and protecting effect can be achieved, and a certain comfortable breathing feeling is brought to the wearer;
2) the intelligent level of the auxiliary mechanism of breathing in is high, can further improve the travelling comfort of the person of wearing.
