Description

Technical Field

[0001] The utility model relates to the technical field of electronic noses, in particular to a portable electronic nose detection device. Background Art

[0002] The applications of electronic noses include environmental monitoring, product quality testing (such as food, tobacco, fermented products, flavors and fragrances, etc.), medical diagnosis, explosive detection, etc. The electronic nose is an electronic system that uses the response of a gas sensor array to identify odors. It is an instrument composed of a selective sensor array and an appropriate recognition method that can identify odors.

[0003] During use, the existing electronic nose detection equipment inserts a sleeve into the patient's nostrils, and the patient's exhaled gas contacts the detector through the air inlet on the partition. The detector is then taken out of the sleeve and connected to an analysis device for data analysis, thereby improving the accuracy of olfactory diagnosis. However, when the sleeve is inserted into the patient's nostrils, mucus in the nasal cavity will adhere to the partition and the sleeve. Since the partition is rotatably connected to the sleeve, it cannot be replaced, making the electronic nose unhygienic and posing a safety hazard in its use. In addition, over time, the mucus will solidify on the partition, causing the patient to have an odor when inserting the partition into the nasal cavity. This will not only affect the accuracy of the detector in detecting odors, but also the patient will have an adverse physiological reaction when smelling the odor on the partition inserted into the nasal cavity. Therefore, a new portable electronic nose detection device is urgently needed to solve these problems. Utility Model Content
