Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

As shown in fig. 1 to 9, a core-replaceable mask comprises an upper frame 1, a lower frame 2, an ear band 3 and a mask filter 4, wherein the upper frame and the lower frame are rectangular strips, the length of the upper frame and the lower frame is the same as that of a disposable medical mask in the prior art, two ends of the ear band 3 are fixedly connected with the end parts of the upper frame 1 and the lower frame 2 on the same side respectively, and the connection mode can adopt welding or riveting; then, first hook surfaces 5 are arranged on the outer side surfaces of the upper frame 1 and the lower frame 2, first rough surfaces 6 are arranged at the top and the bottom of the inner side surface of the mask filter 4, and the first rough surfaces 6 of the mask filter are bonded with the first hook surfaces 5 of the upper frame and the lower frame when the mask filter is used; thus, a complete mask can be formed; by adopting the structure, only the mask filter disc needs to be replaced continuously, and when the service life of the mask filter disc is expired, the mask filter disc is directly torn off from the upper frame and the lower frame; the use is very convenient, and simultaneously, the problem of wasting reusable resources does not exist;

the mask filter 4 adopted in the technical scheme is three-layer or four-layer, the outer layer and the inner layer adopt spun-bonded non-woven fabrics 41, and the middle layer between the outer layer and the inner layer adopts one or two of melt-blown non-woven fabrics 42 and an active carbon steel fiber filter 43;

in the prior art, a mask body of a medical mask is divided into an inner layer, a middle layer and an outer layer;

1. the inner layer is made of skin-friendly material (common sanitary gauze or non-woven fabrics)

2. The middle layer is an isolation filter layer (superfine polypropylene fiber melt-blown material layer)

3. The outer layer is a special material antibacterial layer (nonwoven or ultra-thin polypropylene melt-blown material layer)

If the mask filter 4 adopts a three-layer structure with the middle part being the melt-blown non-woven fabric 42, the structure of the mask is the same as that of the medical mask, and the effect of a disposable medical mask can be achieved; if the mask filter 4 adopts a three-layer structure with the active carbon steel fiber filter 43 in the middle, the mask can play the effects of a common dustproof and haze-proof mask, and the active carbon steel fiber filter can effectively intercept harmful substances in a highly polluted environment, so that the absorption quality is improved; if the performance of the mask is further improved, a composite structure of melt-blown non-woven fabric 42 and an active carbon steel fiber filter sheet 43 can be adopted; therefore, different types of mask filter sheets can meet the requirements of users in different occasions;

in addition, in order to reduce the gap between the mask and the face and prevent the infiltration of dirt from the upper edge of the mask, an accommodating cavity 11 is arranged inside the upper frame 1, and a nose pressing strip 12 is arranged in the accommodating cavity 11; the nose layering 12 is an adjustable nose clip, is the most common plastic strip and is made of polyolefin resin, and has the excellent performances of bending deformation along with the action of external force like metal wires, no resilience after losing the action of external force, and keeping the existing shape unchanged, can be similarly fused with non-woven fabrics, and plays a role of fixing the mask on the nose bridge;

although the gap between the mask and the face can be effectively reduced by using the nasal layering, the gap is often enlarged when a user speaks or some faces act during daily use, when the temperature difference between the inside of the mask and the outside of the mask is too large, hot air exhaled is still upwards exhausted through the gap, and if the user wears glasses, fog is easily generated on the lenses, and the sight of the user is influenced;

in order to solve the problem, the simplest method is to further reduce the gap between the mask and the face, the upper end of the mask can be lifted upwards in real life, then the glasses support of the glasses is placed on the mask, and the gap between the mask and the face is pressed by the weight of the glasses; only this approach has one drawback: the glasses support of the glasses is smooth, the friction force between the glasses support and the mask is small, the glasses can easily slide down, great inconvenience is brought to the use of a user, and the focusing of the eyes of the user is not facilitated; therefore, the lens pads 8 are symmetrically arranged on the outer side surface of the upper frame 1 along the central line of the long side, and the rubber layers are arranged on the surfaces of the lens pads 8, so that the friction force is increased, and the glasses are prevented from sliding downwards; meanwhile, the top of the mirror pad 8 extends out of the end part of the upper frame 1, when the mask is used, the upper end part of the mask does not need to be lifted upwards, a comfortable position of a user is kept, and then the mirror support is directly pressed on the mirror pad, so that the use experience of the user is improved;

furthermore, in order to better solve the problem that the lenses of the glasses users are easy to fog, a detachable hydrophilic non-woven fabric 9 is additionally arranged on the inner side surface of the upper frame 1, a second rough surface 13 is arranged on the inner side surface of the upper frame 1, and a second hook surface 91 is arranged on the top of the side surface of the hydrophilic non-woven fabric 9, so that the hydrophilic non-woven fabric 9 is bonded with the second rough surface 13 of the upper frame through the second hook surface 91; the hydrophilic non-woven fabric 9 used in the method is strip-shaped or narrow-sheet-shaped, the hydrophilic non-woven fabric 9 is padded on the inner side of the upper frame, and the metal strip is bent according to the curve of the nose bridge to be fully attached to the face, so that the gap between the mask and the face is filled by the hydrophilic non-woven fabric 9 padded on the inner side of the mask, the escape of hot air exhaled by people is greatly reduced, and the lenses are not easy to fog and cheer; meanwhile, the hydrophilic non-woven fabric 9 is made of common polypropylene spun-bonded non-woven fabric through hydrophilic treatment, has good water absorption, and can be fully absorbed by the hydrophilic non-woven fabric 9 even in the upward exhalation process of water vapor exhaled in the mask, so that the problem of fogging of the lens can be solved more thoroughly, and the use is safer;

furthermore, in the process of using the daily mask, due to the problem that the mask is matched with the face, the side edge of the mask is not well matched with the face, the airtightness is not good in how to do, the side edge can be tilted to form a mouth, and therefore the function of the mask is easily lost; dust, viruses and the like in the air can directly enter the respiratory tract of a user through the mouth between the side edge of the mask and the face, so that the filtering function of the mask is lost; therefore, a pair of folding hooks 44 are symmetrically and fixedly arranged on the short side edge of the outer side surface of the mask filter 4, the folding hooks 44 are positioned on the central line of the short side edge, the openings of the folding hooks 44 are oppositely arranged, and the folding hooks can be made of hard materials such as metal or plastics; an elastic belt 7 is further arranged between the short edges of the upper frame 1 and the lower frame 2 on the same side, and the length of the elastic belt 7 is smaller than that of the short edge of the mask filter 4; when the mask filter is used, after the mask filter is bonded on the upper frame and the lower frame, the elastic band can be turned to the other side face of the mask filter, namely the outer side face of the mask filter, then the mask is worn on the face, and meanwhile, the elastic band is buckled in the folding hook; the elastic band can contact the side edge of the mask filter piece with the face tightly under the action of the resilience force, and the problem of poor tightness is solved.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
