an anion generator 18 for generating anions to settle the fine particles entering the dust mask body 1;
and a noise power generation device for supplying power to the negative ion generator 18 by using noise.
In this embodiment, the negative ion generator 18 is provided with a switch, a high voltage generator, a negative ion releasing terminal, and a negative ion output interface. The negative ion release end adopts fullerene which is a nano superconducting material similar to C60, almost has no resistance, and can generate a large amount of extremely pure negative ions only under the condition of introducing weak current. The storage battery 17 supplies power to the high-voltage generator to obtain pure direct-current negative high voltage, the direct-current negative high voltage is connected to the negative ion release tip, high corona is generated by the tip direct-current high voltage, a large amount of electrons (e-) are released at high speed, and the electrons are combined with oxygen to generate negative ions.

The sound-electricity conversion principle is as follows: the positive piezoelectric effect is that when the crystal is acted by external force in a certain fixed direction, electric polarization phenomenon is generated inside the crystal, and charges with opposite signs are generated on two surfaces; when the external force is removed, the crystal returns to an uncharged state; when the direction of the external force action is changed, the polarity of the charges is changed; the charge quantity generated by the crystal under the action of force is in direct proportion to the magnitude of the external force. The vibration effect of the sound waves causes the piezoelectric material to generate a positive piezoelectric effect, so that sound energy is converted into electric energy.

the noise power generation device further comprises:
an AC/DC converter 25 for converting the alternating pulse current into direct current;
a capacitor 26 for pre-storing the direct current;
