Abstract

The invention discloses a replaceable mask capable of being used for a long time. The replaceable mask comprises a mask main body, an encircling bracket and an outer layer, wherein the mask main body is attached to the skin and is made of silica gel; a hollow mounting opening is formed in the front part of the mask main body; the encircling bracket is embedded in the mounting opening; at least two penetrating openings in upper and lower positions are formed in the encircling bracket; a replaceable nose filter and a replaceable mouth filter are plugged in the penetrating openings; a philtrum part transverse partition plate is arranged on the inner side of the encircling bracket; the outer layer wraps the outer side of the mounting opening and has supporting performance and waterproof performance; and an air flowing cavity is formed between the outer layer and the encircling bracket. The replaceable mask has good fitting performance; and the inhaling negative pressure of the nose filter and the mouth filter during inhaling is effectively reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to a mask, in particular to a replaceable mask which can be used for a long time. Background technique [0002] A general protective mask has such a three-layer structure: skin-friendly layer, filter layer, and outer layer. The main material of the skin-friendly mask is long-fiber non-woven fabric. Many users are allergic to long-fiber non-woven fabric and cause a series of skin problems. , affecting the quality of life of users and the experience of using products. Skin damage from prolonged mask wearing includes physical pressure damage, urticaria, contact dermatitis, dry skin, and exacerbation of pre-existing skin disorders. The main problem is that the layers of masks are superimposed, which affects the overall air permeability and ventilation. [0003] Secondly, existing masks do not have a modular concept, and the mask parts are not replaceable. With the emergence of the exist...
