Magnetic-electric air purifying mask

Abstract

The invention discloses a magnetic-electric air purifying mask which comprises a magnetic-electric air filtering unit which uses electromagnetic fields for filtering and a mask base frame. A breathing window is formed in the middle of the mask base frame. The magnetic-electric air filtering unit is mounted in the breathing window and comprises a conductive mesh, a conductive induction mesh, a magnetic induction coil and an induction mesh. A power supply is mounted in the mask base frame. An anode output end of the power supply is connected with the conductive mesh, a first end of the magnetic induction coil, and the induction mesh. A cathode output end of the power supply is connected with the conductive induction mesh and a section end of the magnetic induction coil. By the electromagnetic fields in the magnetic-electric air filtering unit, fine dust of the entering air is charged and coagulated, and the coagulated dust is filtered to purify the air. In addition, the magnetic-electric air purifying mask is low in breathing resistance, and widely applicable to masks, and smooth breathing of a wearer is guaranteed.

Description

technical field [0001] The invention relates to a mask, in particular to a magnetic-electric air purification mask. Background technique [0002] At present, the dustproof method of dustproof masks is to filter the dust through the mesh to purify the inhaled air. The effect of filtering and dust removal can generally be improved by reducing the mesh of the filter material, but at the same time, the breathing resistance will increase due to the reduction of the mesh of the filter material. Therefore, the reduction of the mesh of the filter material and the improvement of the dust resistance rate can only reach certain limits. For a long time, multi-layer gauze has been used as filter material for many years. In order to improve the effect, people always try to use better materials as filter material. Animal, plant and mineral fibers have been used as filter material, but the filter material cannot be filtered out. Dust below 5 microns. Foreign countries have also developed...

Problems solved by technology

The effect of filtering and dust removal can generally be improved by reducing the mesh of the filter material, but at the same time, the breathing resistance will increase due to the reduction of the mesh of the filter material. Therefore, the reduction of the mesh of the filter material and the improvement of the dust resistance rate can only reach certain limit

For a long time, multi-layer gauze has been used as filter material for many years. In order to improve the effect, people always try to use better materials as filter material. Animal, plant and mineral fibers have been used as filter material, but the filter material cannot be filtered out. Dust below 5 microns

Foreign countries have also developed ultra-fine synthetic fiber filter materials, which have a better dust-proof effect. However, the contradiction between the dust-resistance rate and breathing resistance of filter-type dust masks cannot be completely resolved from the innovation of filter materials. It is less than 5 microns, and the most harmful dust to the human body is about 1 micron, and it cannot be removed by pure filtration.

Although according to medical explanations, large particles of dust are inhaled into the lungs of the human body in time, relying on the body's own self-cleaning effect, it will also be wrapped in sputum and excreted from the body, but fine dust of about 1 micron will invade into the lungs after being inhaled. The cells of the lungs and respiratory tract of the human body cannot be excreted simply by the self-cleaning function of the human body, resulting in malignant consequences such as poisoning and carcinogenesis

Therefore, simply relying on the previous filtering method can only stop large particles of dust, but can do nothing to the metal dust that is really harmful to human health.
