Embodiment Construction

[0042] see figure 1 . The olfactory simulation device of the present invention is an olfactory simulation device, which is characterized in that it is composed of a main box 1 , a computer processing part 2 , a display part 3 and a power supply circuit 4 .

[0043] An annular test box 11 is arranged in the main chassis 1, and a partition 12 is provided on one side of the annular test box. An air inlet and an air outlet are respectively arranged on both sides of the partition, and an air inlet pipe 13 and an air outlet pipe 14 are respectively penetrating through the air inlet and the air outlet. The intake pipe is provided with a second solenoid valve 16 to control the on-off of the test gas and a first solenoid valve 15 to control the on-off of the recovery gas. The first solenoid valve communicates with oxygen or clean air 5 through the pipeline, and the second solenoid valve passes through the pipeline. It is connected to the sample 6 to be tested; the third electromagnet...

Abstract

The present invention relates to an olfactory simulation device and its olfactory simulation testing method. Said device is formed from main machine box, computer processing portion, display portion and power supply circuit, and said method includes the following steps: a). the odor to be tested can be sucked into ring testing box by means of miniature diaphragm pump, said gas can be quickly passed through sensing membrane surface of every sensor, then discharged from outlet; b). every response produced by every gas sensor when the gas is passed through every sensor can be collected into datacollecting card, passed through A / D converter to obtain a multidimensional response signal; and c). said signal is processed by computer so as to can obtain the type of odor to be tested, integral intensity and its simple component composition, and can be displayed.

Description

technical field [0001] The invention relates to an olfactory simulation device and a olfactory simulation testing method thereof. Background technique [0002] Odor is one of the main indicators to evaluate the intrinsic quality of fragrant products and the quality of ambient air. So far, the evaluation of the aroma quality and style of spices, flavors, cigarettes, wine, tea, soy sauce, vinegar, cosmetics and other items mainly depends on people's sense of smell. Due to the influence of subjective and objective factors such as experience, emotion, and environment, as well as physiological factors such as fatigue, adaptation, and habits, in a sense, sensory methods are difficult to be scientific and objective, and are more difficult to master than physical and chemical analysis methods. However, relying on human senses to monitor the quality of the production process of fragrant items is an arduous and cumbersome task. [0003] For a long time, people have been hoping to de...
