Description

Technical Field

[0001] The utility model relates to the technical field of olfactory perception, and in particular to an olfactory perception device based on a multi-sensor array. Background Art

[0002] The olfactory perception device, also known as the olfactometer, is an intelligent analytical instrument constructed by simulating the principles of biological olfaction. Compared with artificial sensory evaluation methods and modern analytical instruments, it has the advantages of being objective, fast, simple and low-cost. The olfactory perception device intends to study the biological olfactory mechanism from an engineering and technical perspective, draw on its various bionic elements, and improve the two key technologies of the gas sensitive sensor array and information processing algorithm in the olfactory perception device to realize a bionic olfactory perception device system that is closer to biological olfaction in structure, behavior and function. It is generally used in laboratories and can analyze the gas exhaled by the human body and other collected gases.

[0003] The utility model patent with announcement number CN218331443U proposes an olfactory perception device based on multi-sensor fusion, including an olfactory perception meter and a connecting tube, wherein the connecting tube is located at the bottom of the olfactory perception meter, and is characterized in that: the bottom of the connecting tube is fixedly connected to a breathing port, a shell is provided on the right side of the olfactory perception meter, a first clamping block is fixedly connected to the rear side of the bottom of the inner cavity of the shell, a positioning assembly is provided on the front side of the inner cavity of the shell, and a limiting assembly used in conjunction with the positioning assembly is provided on the rear side of the inner cavity of the shell, the positioning assembly includes a second clamping block, a connecting column is fixedly connected to the left side of the second clamping block, a connecting block is fixedly connected to the rear side of the connecting column, a limiting column is provided on the front side of the connecting column, and a spring is provided on the surface of the limiting column.

[0004] In the above case, when working, the gas is collected through the fixed exhalation port and then transported to the inside of the olfactory sensor. The gas is analyzed by the olfactory sensor and then data is obtained. However, in actual work, different gases need to be collected and analyzed, and contamination will occur between different gases. In addition, when analyzing the exhaled gases of different human bodies, the human body needs to exhale into the exhalation port in turn, so that the device needs to spend time to clean the exhalation port each time it is tested, which reduces the working efficiency of the device and increases the workload of the tester.

[0005] Therefore, the present invention provides an olfactory perception device based on a multi-sensor array to meet the needs. Utility Model Content
