[0002] A mask is a health protection product worn on the mouth and nose to filter and purify the air and control the spread of respiratory infectious diseases. The widely used filtering masks currently mainly use two layers of non-woven fabrics with a layer of filter material. The metal nose bridge wrapped in the non-woven fabric is bent along the shape of the nose bridge to improve the sealing performance. Most of them are disposable masks and cannot be reused. Reusable masks wrap the filter material on the outside of the mask bracket, and the appearance is monotonous and lacks aesthetics. Air-supplied masks are generally used for anti-virus, disaster relief and other aspects. They are inconvenient to wear in daily life and damage the appearance. Inventing a mask and process technology with replaceable filter membrane, adaptive face shape sealing, beautiful and comfortable to wear, convenient for 3D printing and 3D copying, and realizing personalized clothing design customization and large-scale efficient production is an innovative development direction. Summary of the invention

[0003] In order to solve the problems of high disposable consumption cost, great pressure on resources and environment, insufficient protective function and aesthetics, and realize the transformation of masks into clothing with replaceable core filter membrane, disinfection and reuse, adaptive facial sealing, beautiful and comfortable, personalized design, 3D printing and mass production of 3D copying, the present invention proposes a new solution of masks with reusable artistic modeling frame and quick-change filter membrane. The mask is composed of an artistic frame, a nanofiber filter membrane, a flexible hose, a metal plastic strip and a hanging rope. The mask frame has a circle frame that fits the face and can completely cover the nostrils and lips. The mask frame frame has a hollow curved surface protruding outward to form a breathing cavity. The hollow pattern can be an artistic graphic or a simple frame with a paper-cut art pattern attached to the outside. The height of the protrusion is preferably not to affect the eye's field of vision. A three-dimensional facial conformal groove is provided on the side where the mask frame frame fits the cheek. The metal plastic strip is inserted into the hose to form an elastic tube that acts as a seal. The nanofiber filter membrane is laid in the mask frame, and the edge of the nanofiber filter membrane is pressed into the groove of the mask frame frame by the elastic tube. The mask frame frame is provided with a hanging ear, and the hanging rope is inserted into the hanging ear to tie the mask to the head or hang it on the ears when it is worn.

[0004] The present invention discloses a quick-change filter mask with an artistic modeling frame. The mask frame is fine-tuned on the mask features wrapped around the bridge of the nose and cheeks based on the hollow curved frame template according to the data of the basic face shape of the general public, the face 3D model, the photos of the personal side face and the front face, so as to achieve a three-dimensional modeling design with good fit. This design improves the wearing comfort and sealing effect of the mask. The hollow pattern of the mask frame is designed according to the user's requirements, and can also be designed or made into an artistic paper-cut shape. This freely designed personalized artistic mask not only meets the customer's requirements for aesthetics, but also reflects the flexibility of mask design and production. Therefore, the mask of the present invention is called a mask with an artistic modeling frame. Small stickers or paper-cuts can be pasted on the outside of the mask frame to increase personal artistic interest. The mask frame can be made by a mass production method of 3D copying such as thermoforming pressing or vacuum blistering, injection molding, etc., or by a flexible and convenient single-piece customization or small-batch production method such as 3D printing.

[0005] The invention discloses a quick-change filter membrane mask with an artistic modeling frame. The nanofiber filter membrane can be prepared by various filter membrane production methods such as polymer melt differential electrospinning, solution electrospinning of environmentally friendly and safe solvents, melt jet spinning, biaxial stretching and nuclear pore membrane, microfiber deposition papermaking process, etc., with synthetic polymers such as PLA, PP, PAN, PTFE or natural polymers such as cellulose as raw materials.

[0008] The invention discloses a quick-change filter membrane mask with an artistic frame, wherein the length of the metal plastic strip is greater than the length of the hose, the hose is completely embedded in the groove of the frame of the mask, and the reserved section of the metal plastic strip outside the hose coating can be bent upward into a U-shape or other shapes and outwardly press the filter membrane to form a certain breathing gas volume space to ensure breathing comfort. The groove structure on the inner side of the mask frame near the edge clamps the elastic hose and the filter membrane, and the elastic hose is adjusted to be in close contact with the face, nose bridge and other parts and slightly deformed by force, thereby ensuring the sealing effect of the breathing gas.

[0009] The invention discloses a quick-change filter membrane mask with an artistic frame, wherein the length of the metal plastic strip is greater than the length of the hose, the hose is completely embedded in the groove of the mask frame frame, and the reserved section of the metal plastic strip outside the hose can be bent upward into a U-shape or other shapes and outwardly support the filter membrane to form a certain breathing gas volume space to ensure breathing comfort. The reserved section of the metal plastic strip is also covered with a hose that is the same as the hose embedded in the groove of the mask frame frame, or a softer hose is covered, so that the reserved section of the metal plastic strip has good plasticity, reduces elasticity, and enhances its support for the nanofiber filter membrane. Under the action of the reserved section of the metal plastic strip, the nanofiber filter membrane can fit the hollow structure of the mask frame as much as possible to increase the breathing cavity.

[0010] The reserved section of the metal plastic strip can also be wrapped with film or tape, and the bent shape of the reserved section of the metal plastic strip can be various, such as fork shape or heart shape, with a certain support area, so as to provide better support and clothing interest. The reserved section of the metal plastic strip can also form support on the bridge of the nose and in the middle of the lips along the symmetry axis of the mask frame.

[0011] The invention discloses a quick-change filter membrane mask with an artistic frame. The mask frame, elastic hose and plastic metal strip can be used for a long time and multiple times. When the mask is worn for a period of time and the protective function fades, the elastic hose can be conveniently removed and the nanofiber filter membrane can be replaced.
