The adhesion mode can be adhesion by using glue or magic tape.

Wherein, the detection indicator 2 contains one or more of fat-soluble pigment, pH indicator and fluorescence indicator, for example, made into ink or pigment, paint, etc. For example, the fat-soluble pigment can be tetraterpenoid organic derivatives or natural fat-soluble pigments such as chlorophyll, crocin or capsorubin. Because the fat-soluble pigment is insoluble in water and soluble in oil substances, and the bacteria can generate and secrete the oil substances in the metabolism process, when the content of the lipid substances exceeds a certain limit, the lipid substances can generate color reaction with the fat-soluble pigment, so that the content of the bacteria on the protection body 1 can be detected, and then when the amount of the bacteria is more, the protection articles can be replaced in time.

For another example, the detection indicator 2 contains a fluorescent indicator, and the detection principle of the fluorescence method is as follows: the fluorescent indicator can be a nucleic acid fluorescent dye which can be embedded into a DNA double strand and can emit fluorescence under the fluorescence excitation of a specific excitation wavelength so as to detect viruses, such as Zika virus, and a related report is provided in patent 2019109597167.

In other embodiments, referring to fig. 8, the detection indicator 2 is provided with a micro-suction fan 3 for introducing air around the protection body 1 to the detection indicator 2, thereby facilitating collection of bacteria, viruses, etc. around the protection body 1. The detection indicator 2 may be further provided with a battery. The detection indicator 2 includes a reagent kit 21 and a specimen 4 that changes color when brought into contact with a sample, and the specimen 4 contains one or more of a fat-soluble dye, a pH indicator, and a fluorescent indicator.

The number of the U-shaped tubes may be determined as needed, and a plurality of the U-shaped tubes may form a wave shape. Referring to fig. 8, the micro-extraction fans 3 may be respectively disposed at two ends of the U-shaped tube 23, or the micro-extraction fan 3 may be disposed at one end of the U-shaped tube 23, the other end of the U-shaped tube 23 is disposed with a sealing cover, and the sealing cover is disposed with a plurality of micro-pores as ventilation holes, so that the liquid-like detection body is retained in the U-shaped tube 23, and liquid is prevented from splashing out. The liquid specimen 4 may contain, for example, a lysis solution for lysing virus together with a pH indicator or a fluorescence indicator. The detection principle of the fluorescent indicator is as follows: the fluorescent indicator can be a nucleic acid fluorescent dye which can be embedded into a DNA double strand and can emit fluorescence under the excitation of fluorescence with a specific excitation wavelength so as to detect viruses, and a specific excitation wavelength generator is also arranged in the detection indicator 2. The detection principle of the pH indicator color development method is as follows: when a DNA polymerase binds a deoxyribonucleotide molecule to a newly synthesized DNA double strand, a hydrogen ion is generated as a by-product, and when a large amount of hydrogen ions is generated, the increase in the hydrogen ion concentration lowers the pH of the reaction system in specimen 4, and the pH indicator in specimen 4 changes color, whereby a virus such as Zika virus is detected. There are related reports in patent 2019109597167. The reagent cartridge 21 of the detection indicator 2 is further provided with a heater for heating the liquid-like detection body 4 and thereby allowing the reaction in the detection body 4 to proceed normally.
