Description

Technical Field

[0001] The utility model relates to the technical field of machine olfactory equipment, in particular to an olfactory host. Background Art

[0002] With the application of various gases, a variety of toxic and harmful gas products are generated in large quantities, posing a threat to human health and safety. Various gas detection technologies have emerged, such as gas and liquefied gas alarms, smoke (fire) alarms. Especially since Wilkens and Hatman proposed the concept of electronic nose in 1964, gas sensing technology is developing towards a higher level - electronic nose, that is, an intelligent system with certain gas and odor discrimination capabilities.

[0003] Existing electronic noses generally include a control device and an olfactory sensor, and the two are designed as an integrated structure. They can only meet the function of identifying a single compound or a mixed gas, and cannot meet other functions of machine olfactory research experiments, such as sample gas flow control, which is inconvenient for users to use; the olfactory sensor is a vulnerable part. Once the olfactory sensor is damaged, the electronic nose needs to be disassembled and replaced with a new one, which is inconvenient for maintenance and has high maintenance costs. Utility Model Content

[0004] Based on this, it is necessary to provide an olfactory host to address the problems that the existing electronic nose cannot meet the functional requirements of machine olfactory research experiments, and the electronic nose is not easy to repair and has high maintenance costs.
