In an embodiment of the present invention, the barrier layer 10 is a protective cover with ear loops and a face covering, which is used to block harmful substances. The protective cover is a three-layer structure, which has a waterproof layer, a harmful component barrier layer and a skin-friendly layer: the outermost layer is the waterproof layer, which is made of polypropylene or other waterproof materials, which can be used to block droplets, blood and other substances. The middle layer is a barrier layer with a bacterial or viral barrier function. The innermost layer is a skin-friendly layer that absorbs water and improves wearing comfort. However, the structure and function of the barrier layer 10 have been widely used in traditional masks, and are not the focus of the present invention, so it is unnecessary to repeat them.

In an embodiment of the present invention, the color changing layer 20 covers the outer side of the blocking layer 10 . The color-changing layer 20 is an aerosol layer coated with a color-changing agent, and the color-changing agent will display different colors for different harmful substances; for example, the color-changing agent may be cobaltous chloride, which will be exposed to droplets or The color of the substance with moisture such as blood changes; however, the types of color-changing reagents are not limited to the above, and can be changed according to the needs of use. For example, the color-changing reagent can also be a fluorescent agent for detecting bacteria or viruses. When the agent comes into contact with bacteria or viruses, it fluoresces. When the harmful substance touches the color-changing agent on the color-changing layer 20, the color-changing agent in the color-changing layer 20 will change color, so that the user can know whether the smart mask 1 touches the color-changing agent by watching whether the color-changing layer 20 changes color. harmful materials.

In an embodiment of the present invention, as shown in FIG. 2 and FIG. 3 , the wafer set 30 is connected to the color-changing layer 20 . The chip set 30 includes a detection module 31 , an identification label 32 , a blockchain module 33 , a positioning module 34 and a network module 35 . The detection module 31 includes a plurality of color-sensitive detectors 311 , and each of the color-sensitive detectors 311 is connected with a circuit (the dotted line in FIG. 2 ) and is uniformly arranged on the color-changing layer 20 . Each color-sensitive detector 311 is used to detect whether the discoloration layer 20 around the setting position of each color-sensitive detector 311 is discolored. Since each color-sensitive detector 311 is evenly arranged on the discoloration layer 20, each color-sensitive detector 311 can detect whether a part of the color-changing layer 20 is in contact with the harmful substance and changes color, so that it can be confirmed that the harmful substance touches the color-changing layer 20. Touch the position of the color-changing layer 20 .

The identification tag 32 is a radio frequency identification (RFID) or a Near Field Communication (NFC) tag, and the identification tag 32 stores a circulation history of the smart mask 1 . The circulation process includes the manufacturing date, storage date, manufacturing location, storage method, storage location, and transportation process of the smart mask 1. The block chain module 33 includes a computing chip and a wireless communication chip. The block chain module 33 is connected with the identification tag 32 and a block chain network 300 signal to record the circulation history recorded by the identification tag 32 in the block chain. Link network 300. With the traceability of the blockchain 300 and the characteristics that the records are not easily tampered with, the circulation process of the smart mask 1 can be recorded and tracked perfectly. The positioning module 34 is a global positioning system (Global Positioning System) chip, and the positioning module 34 is used for positioning the smart mask 1 to determine the current position of the smart mask 1 .

In an embodiment of the present invention, as shown in FIGS. 1 to 3 , when the user needs to use the smart mask 1 of the present invention to block harmful substances, the smart mask 1 can be worn on the face. When the air flows to the smart mask 1, the harmful substances in the air will also blow to the smart mask 1, and the harmful substances will first pass through the discoloration layer 20; The color changes when it touches the harmful substance. In this way, the user can know whether the smart mask 1 touches the harmful substance by watching whether the color-changing layer 20 changes color; and when most of the color-changing layer 20 changes color, The user can know that the smart mask 1 has come into contact with many harmful substances, so its barrier function should be weakened, and the smart mask 1 may be discarded.

After the harmful substance passes through the discoloration layer 20, it will continue to touch the barrier layer 10, and the barrier layer 10 will block the harmful substance to prevent the user from inhaling the harmful substance. In addition, each color-sensitive detector 3111 on the detection module 31 can detect whether a part of the color-changing layer 20 contacts with harmful substances and changes color, so that the position where the harmful substances touch the color-changing layer 20 can be confirmed. The network module 35 can also transmit the discoloration result of the discoloration layer 20 detected by the detection module 31 and the positioning information of the positioning module 34 to the management server 200 for the management server 200 to record the discoloration result and positioning Information.
