The invention provides a frame type mask with a replaceable filter membrane, which consists of a mask body outer shell, the filter membrane, a mask body inner shell and an elastic ear band, wherein the mask body outer shell, the filter membrane and the mask body inner shell are sequentially sleeved together to cover the mouth and the nose of a person; the outer shell and the inner shell of the cover body are provided with hollow patterns, and the shapes of the patterns can be individually designed to meet different requirements of customers; the elastic ear belt has two ends with cylindrical protrusions, which form interference fit with the outer cover and the inner cover, and is sleeved on the head or behind the ear to ensure the tight fit of the inner and outer covers.
The invention relates to a frame type mask with a replaceable filter membrane, wherein an outer shell of the mask body is made of soft elastic materials, such as latex, elastic polyurethane, rubber or flexible PVC (polyvinyl chloride), an inner shell of the mask body is made of hard elastic materials, such as hard polyurethane or flexible polyethylene, and the like, the inner shell of the mask body plays a supporting role, a breathing cavity is supported at the mouth and the nostrils, breathing and speaking are not influenced, the outer shell of the mask body is soft, so that sealing with the face is conveniently formed, and the filter membrane of the mask is also convenient to replace.
The invention relates to a frame type mask with a replaceable filter membrane, which is characterized in that a mask body outer shell and a mask body inner shell are integrated, only a small part of the edge of the mask body outer shell is connected with the edge of the mask body inner shell to play a role of a hinge, the mask body outer shell and the mask body inner shell can be opened by taking a connecting part as an axis, so that the mask filter membrane can be conveniently replaced, in addition, less alignment time is spent in assembly, the operation is more convenient, the mask body outer shell and the mask body inner shell cannot be separated in cleaning, the scattering is avoided, the disorder brought to matching.
The invention relates to a frame type mask with a replaceable filter membrane, wherein the covering area of a mask outer shell on the face is larger than that of a mask inner shell on the face, the mask outer shell is provided with a groove with the same shape as the edge of the mask inner shell, the mask inner shell can press the mask filter membrane to be embedded into the groove, the edge of the mask outer shell plays a role in sealing under the action of elastic ear band pulling force, and the mask inner shell plays a role in supporting the mask outer shell and compressing the mask filter membrane.
The mask filter membrane of the frame type mask with the replaceable filter membrane is provided with the through holes matched with the openings of the inner shell and the outer shell of the mask body, so that the filter membrane is ensured to be fixed between the inner shell and the outer shell of the mask body and not to slide.
The mask filter membrane of the frame type mask with the replaceable filter membrane is a reusable filter membrane, and the process can be prepared by adopting methods such as polymer melt differential electrostatic spinning, solution electrostatic spinning of environment-friendly and safe solvents, melt-blown air spinning and the like, and takes synthetic macromolecules such as PP, PLA, PAN, PTFE and the like or natural macromolecules such as cellulose and the like as raw materials.
The filter membrane is independently packaged like wet paper towels, can be in a plane shape or a three-dimensional curved surface shape, and can be obtained by adopting a rolling cutting or die cutting mode.
The inner cover body shell and the outer cover body shell of the frame type mask with the replaceable filter membrane can be repeatedly used. The elastic ear belt is made of elastic material, and can be taken down when the filter membrane is replaced. The filter membrane can be used once, and can also be used for a plurality of times after the filtration efficiency is recovered by cleaning and disinfection.
In conclusion, the mask has the advantages of good sealing performance, comfortable wearing, repeated use of the inner shell and the outer shell, convenient replacement of the filter membrane, fashionable appearance, capability of being customized individually and the like. Can meet the long-term wearing requirement of people.
