The utility model comprises inlet channel and test chamber based on the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, the curved loudspeaker tubular of inlet channel, and its minor diameter one end and test chamber are tightly connected; Be provided with gas sensor array near the inlet channel end in the test chamber, be provided with controlled aspirator away from the inlet channel end, the test chamber bottom is provided with vent port; Described gas sensor array comprises the gas sensor of MQ135, TGS2600, TGS2602, TGS2620 model.
Further, also be provided with data processing circuitry plate in the test chamber of the utility model based on the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, be inlaid with display window on the test chamber shell.
Further, the utility model is 30-50mm based on the gas sensor array of the portable catsup and pickled vegetables odor detection instrument of bionic olfactory apart from the distance of inlet channel collar extension.
Further, the utility model is speed-regulating fan based on the controlled aspirator of the portable catsup and pickled vegetables odor detection instrument of bionic olfactory.
Further, the utility model also is provided with the powered battery parts based on the portable catsup and pickled vegetables odor detection instrument of bionic olfactory.
The utility model is the gas sensor that adopts multiple model based on the useful technique effect of the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, detects the different component gas that comprises in the salted vegetables smell targetedly; Simulating human is smelt the air-breathing mode of news, makes testing result more smell the news result close to the mankind; Adopt portable structure and powered battery, use more convenient.
Description of drawings
Accompanying drawing 1 is that the utility model is based on the structural representation of the portable catsup and pickled vegetables odor detection instrument of bionic olfactory.
Below in conjunction with the drawings and specific embodiments the portable catsup and pickled vegetables odor detection instrument of the utility model based on bionic olfactory is further described.
Embodiment
Accompanying drawing 1 is that the utility model is based on the structural representation of the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, among the figure, 1 is inlet channel, 2 is the test chamber shell, and 3 is data processing circuitry plate, and 4 is gas sensor array, 5 is speed-regulating fan, 6 is the powered battery parts, and 7 is vent port, and 8 is display window.As seen from the figure, the utility model comprises inlet channel 1 and test chamber based on the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, inlet channel 1 curved loudspeaker tubular, and its minor diameter one end and test chamber are tightly connected; Be provided with gas sensor array 4 near inlet channel 1 end in the test chamber, be provided with controlled aspirator away from inlet channel 1 end, the test chamber bottom is provided with vent port 7; Described gas sensor array 4 comprises the gas sensor of MQ135, TGS2600, TGS2602, TGS2620 model.
Portable catsup and pickled vegetables odor detection instrument based on bionic olfactory shown in Figure 1 only is the assembly state diagram of a kind of specific embodiment of the present utility model, wherein, test chamber middle part leans against on the chamber wall of test chamber and also is provided with data processing circuitry plate 3 and powered battery parts 6.At this, as an instantiation of controlled aspirator, adopt speed-regulating fan 5 as controlled aspirator.The test chamber bottom, namely speed-regulating fan 5 belows are provided with vent port 7, are used for overflowing of test gas.Be inlaid with display window 8 on the test chamber shell 2.When this detector arranges powered battery parts 6, the interface of external power supply can be set also, under different test conditions, can choose different power supply modes.
In other assembling mode, parts such as data processing circuitry plate 3, powered battery parts 6 and display window 8 are not as long as hinder the arrangement of inlet channel 1, gas sensor array 4 and speed-regulating fan 5, as can independently being arranged at outside the test chamber.
When the utility model is worked based on the portable catsup and pickled vegetables odor detection instrument of bionic olfactory, speed-regulating fan 5 rotates gas to be measured is sucked test chamber by inlet channel 1, gas to be measured and gas sensor array 4 be fully reaction in test chamber, the signal of gas sensor array 4 responses is again through data processing circuitry plate 3 analyzing and processing, finally by display window 8 outputs.
Described inlet channel 1 adopts imitative nose runner shape to arrange, and is similar with the human body nasal meatus, is the loudspeaker tubular, the big end of diameter one end is little, little an end and test chamber join, and test airflow is easy to suck, and has improved smell to be measured and gas sensor array 4 catalytic efficient.Speed-regulating fan 5 is a kind of concrete form of controlled aspirator, and other the air pump devices that can regulate inspiratory capacity size and speed also can be used for the present invention.The air-breathing intake method of this speed-regulating fan 5 simulation lungs, by controlling fan rotating speed size is set, and then the control intake velocity.Bionical air-breathing mode like this and inlet channel 1, make air-flow to be measured evenly, stablize sample introduction, improved test accuracy.
The gas sensor of described four kinds of models is used for gas sensor array 4 simultaneously.Smell screening, experiment acquisition that the gas sensor of these models ferments and pickles generation at catsup and pickled vegetables, 4 pairs of catsup and pickled vegetables smells of the gas sensor array sensitivity that forms, response is strong, can buy to obtain the semiconductor gas sensor of producing as Japanese Figaro company by commercial sources.Gas sensor array 4 is except the gas sensor that comprises these models, and not getting rid of has the gas sensor of other model to appear in the array as booster action.
When described gas sensor array 4 is 30-50mm apart from the distance of inlet channel 1 collar extension, it is approximate apart from the distance of nasal cavity collar extension that gas sensor array 4 is smelt quick cell apart from the distance of inlet channel 1 collar extension and biological olfactory system, and gas sensor array 4 reactions of this position are sensitiveer, test is more accurate.
Described data processing circuitry plate 3 comprises circuit such as conversion, amplification, denoising.
