Problems solved by technology

[0004] (1) poor fit and poor sealing performance with the mouth and nose of the human body;
[0005] (2) For those who wear glasses, the exhaled moist airflow cannot be prevented from going up along the nasolabial fold, and it is easy to condense into fog on the lens and block the line of sight;
[0006] (3) Repeated removal and wearing, the aluminum bead will lose its original performance;
[0007] (4) If worn for a long time, the root of the ear will feel pain;
[0008] (5) It not only covers the mouth and nose, but also covers the cheeks. Covering the cheeks does not improve the protective effect, but seriously wastes materials

Abstract

The invention relates to a wearable carrier for respiratory filtration. The wearable carrier is worn in a nasolabial groove on a face of a human body and comprises a shell, a front cover, a flexible fitting piece and fixing belts, wherein the shell is integrally formed by a hard material, a front panel of the shell is provided with a ventilation hollow, the front cover is detachably fixed at the ventilation hollow, a filter layer is clamped between the front cover and the front panel, and the front cover is provided with a ventilation hole; the flexible fitting part is integrally formed by adopting a flexible skin-friendly material and comprises a nose fitting part and an mouth fitting part adapting to the shapes of a mouth and a nose of the human body, the nose fitting part comprises a nose circumference adapting surface and nose breathing through holes, the mouth fitting part comprises a mouth circumference adapting surface and a mouth breathing through hole, and the flexible fittingpart is adhered to the shell; and the carrier is fixed on the nose and mouth of the human body through the fixing belts fixed on the shell, and the human body breathes through the ventilation hole inthe front cover. According to the technical scheme, a rigid-flexible combined structure is adopted, so that the wearable carrier is good in fit with the mouth and nose of the human body, the stability is good during repeatedly using, and the replacement material cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of protective appliances, in particular to a carrier for wearable breathing filters. Background technique [0002] Existing masks used for conventional medical protection and COVID-19 protection are generally made of three layers of non-woven fabrics: a water-blocking layer, a filter layer and a skin-friendly moisture-absorbing layer. The aluminum bead adjusts the nose contour. [0003] The shortcoming that above-mentioned conventional mouth mask exists has: [0004] (1) poor fit and poor sealing performance with the mouth and nose of the human body; [0005] (2) For those who wear glasses, the exhaled moist airflow cannot be prevented from going up along the nasolabial fold, and it is easy to condense into fog on the lens and block the line of sight; [0006] (3) Repeated removal and wearing, the aluminum bead will lose its original performance; [0007] (4) If worn for a long time, the root of the ear ...
