A multi-layer mask

Abstract

The invention discloses a multilayer mask, belongs to the field of sanitary appliances and solves the problem that a mask has a poor effect of filtering dust or low breathability. The multilayer mask comprises an inner layer, an outer layer and a filter layer comprising at least one layer of gauze, wherein the inner layer and the outer layer are connected into a whole on the top side; the outer surface of the inner layer is provided with a side A of a fastener; the inner surface of the filter layer is provided with a side B of the fastener corresponding to the side A of the fastener of the inner layer; the outer surface of the filter layer is provided with a side A of a fastener corresponding to the side B of the fastener on the inner surface of the filter layer; the inner surface of the outer layer is provided with a side B of the fastener corresponding to the side A of the fastener on the outer surface of the filter layer; the side A and the side B on any two layers can be fastened; the outer surface of the filter layer is coated with a sunflower seed oil layer; edges of the inner layer and the outer layer which can be separated from each other are provided with a sealing zipper used for sealed connection between the inner layer and the outer layer. The number of filter layers can be increased or decreased, sunflower seed oil forms an oil film to filter dust but not hinder oxygen, the filter layers are convenient to assemble and disassemble, and the cost of independently adding oil films is low.

Description

technical field [0001] The invention relates to the field of sanitary appliances, in particular to a multi-layer mask. Background technique [0002] Air pollution is becoming more and more serious, and people have to use masks when traveling in many cases. The cost of medical masks is relatively low, but the effect of filtering fine dust is not good because they are too thin; although some cotton masks have a certain thickness, they still cannot filter some pollutants with small particles because they only use simple cotton nets, more The ground is to play the role of cold protection; and the price of the special mask is relatively high, it is inconvenient to clean, and the air permeability is not good. Contents of the invention [0003] The object to be achieved by the present invention is to provide a multi-layer mask, which is low in cost, easy to clean, and adaptable to various environments. [0004] In order to achieve the above object, the present invention adopts ...
