High-breathability mask with adjustable protection effect

Abstract

The invention relates to the technical field of medical protection, and discloses a high-breathability mask with an adjustable protection effect. The high-breathability mask comprises a mask layer, wearing parts, a supporting frame, resistance reducing parts, a function filtering part and an adaptive frame, wherein the supporting frame is bonded to the inner side of the mask layer through a hot melt adhesive, a fixing position is arranged in the middle of the inner side of the supporting frame, a fixing base is arranged on the outer side of the supporting frame, fixing bases are located on the left side and the right side of the fixing position, the number of the wearing parts is two, the wearing parts are located on the two sides of the mask layer correspondingly, the wearing parts are bonded between the mask layer and the supporting frame through the hot melt adhesive, the number of the resistance reducing parts is two, the resistance reducing parts are installed on the fixing bases correspondingly, the function filtering part is installed on the fixing position, the adaptive frame is adhered to the inner side of the mask layer through the hot melt adhesive, the adaptive frame is in butt joint with the supporting frame, and a nose groove is further formed in the upper side of the adaptive frame. The problems that a traditional mask is prone to collapse, poorer in filterability and air permeability, small in protection effect and incapable of meeting the protection requirements of people are solved.

Description

technical field [0001] The invention relates to the technical field of respiratory protection, in particular to a highly air-permeable mask with adjustable protective effect. Background technique [0002] Ordinary civilian flat masks, medical masks, KN95 masks and other non-woven masks based on melt-blown materials are all disposable products and cannot be washed. The ventilation area used is actually the cloth near the nose and lips, which has a limited area. In addition, the resistance of the ordinary melt-blown filter material is high, causing the mask to hold your breath after wearing it for a long time. However, when using expensive low-resistance water electret filter material, it can effectively reduce the resistance but has The bottleneck of the effective ventilation area, and most of the meltblown materials are not used as the main ventilation area, which is a waste of cost; and washable masks often use the form of insert filter material, which has little protective...
