Electric fresh air mask with dust removal filter material convenient to replace

Abstract

An electric fresh air mask with a dust removal filter material convenient to replace comprises a mask front piece made of the dust removal filter material, wherein a supporting piece made of engineering plastic is arranged behind the mask front piece, a plurality of air holes are formed in the surface of the supporting piece, a rear piece made of the engineering plastic is arranged behind the supporting piece, and a groove concaved backwards is formed in the middle of the rear piece. A fan is fixed in the groove in the middle of the rear piece, an exhaust hole is formed in the side wall of thetop or the bottom of the groove, the left end of the rear piece and the right end of a left elastic insertion sheet are connected into a whole, the left elastic insertion sheet is inserted between aleft cloth pressing strip and the mask front piece from an left insertion opening, and the right end of the rear piece and the left end of a right elastic insertion sheet are connected into a whole. The right elastic inserting sheet is inserted between a right cloth pressing strip and the mask front piece from a right inserting opening. The electric fresh air mask with the dust removal filter material convenient to replace is good in dust removal effect, high in efficiency and capable of enabling a person wearing the mask to breathe smoothly without feeling suffocated; and the sanitation of the mask can be ensured by replacing the dust removal filter material, and the use cost is reduced.

Description

technical field [0001] The invention relates to an electric fresh air mask which is convenient for replacing dust-removing filter materials. Background technique [0002] The mask can be worn on the mouth and nose to filter the air in the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. It is mostly made of cloth or paper. But existing mouth mask can make people feel strenuous, oppressed when breathing after wearing, and feel that breathing is not smooth. And the existing electric fresh air respirator that utilizes blower fan to drive the air intake to be convenient to replace the dust removal filter material usually evolves from the gas mask, which seems heavy and unattractive on the whole, and has a relatively complicated structure and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a dust removal effect, high efficiency, light shape, in line with the...
