Anti-dust respirator with intelligent breathing ring

Abstract

The invention provides an anti-dust respirator with an intelligent breathing ring. According to the technical scheme, the anti-dust respirator comprises a respirator body and the intelligent breathing ring, wherein the respirator body and the intelligent breathing ring are detachably connected in a spirally buckled mode. The respirator body is provided with a breathing ring base. A fixed shaft is arranged at the center of the breathing ring base. The exterior of the intelligent breathing ring is in a transparent organic plastic cylinder shape. The intelligent breathing ring internally comprises a flow guide fan blade, a magnetic bearing motor, a filter cotton web, a flow guide grating cover and a filter efficacy ring. The filter efficacy ring is connected with the flow guide grating cover in a buckled mode. The two ends of the magnetic bearing motor are connected with the filter cotton web and the flow guide fan blade respectively. The end of the filter cotton web is embedded into the outer ring of the flow guide grating cover. The end of the flow guide fan blade is connected with the breathing ring base. The breathing ring base, the flow guide fan blade, the magnetic bearing motor, the filter cotton web, the flow guide grating cover and the filter efficacy ring are connected into a whole through the fixed shaft of the breathing ring base in a penetrating and sleeving mode, driven by the magnetic bearing motor and assembled into a small fan through mechanical connection and leads filtered air into the respirator body. The anti-dust respirator with the intelligent breathing ring is simple in structure, the plastic parts are low in weight, assembling, maintaining and replacing are convenient, and the anti-dust respirator has remarkable economic benefits.

Description

technical field [0001] The invention relates to a dustproof mask, in particular to a dustproof mask with an intelligent breathing ring. Background technique [0002] At present, for dust masks, filtration efficiency or breathing resistance often cannot be taken into account. Masks that emphasize filtration efficiency, especially those that protect against fine particle pollution such as pm2.5, are often achieved by increasing the number of layers of filter material and the compactness of the filter material, which increases the breathing resistance and makes the wearer feel oppressed. Increase the physiological load of the wearer, especially for those who need to wear masks for a long time, it has caused certain health damage; masks that emphasize reducing breathing resistance often increase the air permeability of the filter material, but cannot achieve the effect of filtering and dust removal. In particular, it cannot protect against fine particle pollutants such as pm2.5...
