Most of the existing masks are of a disposable structure, which results in the disadvantage of waste of materials; for this reason, the new model integrates the structure of the removable middle layer through the design of the 3D three-dimensional structure of the front and back layers, and becomes the daily protective type of the washable front and back layers. Masks.

In order to achieve the above-mentioned creative purpose, the present invention provides a removable mask, which is provided with a mask body, a nose positioning steel bar is combined on the top of the mask body, and a band is respectively combined on the left and right edges of the mask body. A front layer cloth and a back layer cloth are provided on the front and back sides of the mask body respectively, and the surface layer cloth is combined with the periphery of the back layer cloth to form a pocket between the two, and a The socket communicating with the pocket is provided with a removable middle layer in the pocket.

Furthermore, the surface cloth or the inner cloth of the present invention can be polyethylene terephthalate, nylon, polypropylene, rayon, acrylic, cotton, wool, silk, hemp, lyocell or Modal fabric.

Preferably, the intermediate layer of the present invention is an activated carbon cloth, a polytetrafluoroethylene film, a nanofiber film, a needle-rolled cloth, a spunbond nonwoven fabric, a meltblown nonwoven fabric or a composite nanofiber membrane thereof.

Preferably, the present invention packs the mask body in a paper bag or a bag.

When the new model is used, the middle layer of the main filtered air needs to be replaced within one day. When replacing, the old middle layer is taken out of the pocket from the socket, and the new middle layer is put into the pocket from the socket for replacement; and When the body of the pocket is dirty, it can be irradiated with sunlight and ultraviolet light, and it can be washed and dried for repeated use.

The effect of the new type is that the new type can be washed multiple times through the front and back layers of the mask body, and the design of the removable middle layer inside the pocket has the saving effect of reusing the mask body. In addition, the protective effect of filtering air through the middle layer is good. A daily protective mask.

In order to understand the technical features and practical effects of the present invention in detail, and can be implemented in accordance with the content of the specification, the preferred embodiment shown in the drawings is further described in detail as follows.

Please refer to the preferred embodiment of the present invention shown in FIGS. 1 to 4, the present invention provides a removable mask, preferably, the antibacterial rate is more than 90%; the protective effect is more than 90% (Class B); filtration The efficiency to be tested is estimated to be more than 90% (level III); inhalation resistance ≤ 175Pa, exhalation resistance ≤ 145Pa, and in accordance with GB/T 32610-2016 daily protective mask technical specifications. The removable mask is equipped with a mask body 10 , A nose positioning steel strip 11 is combined on the top of the mask body 10, and a strap 12 is attached to the left and right edges of the mask body 10 respectively, each strap 12 is an elastic strap and is attached to at least one strap 12 Around the ring is a buckle 121, in which:
