The working principle and the using process are as follows:
when in use, liquid alcohol is added into the space of the inner cavity of the detection box 1 below the partition plate 14 through the adding pipe 201, and the adding pipe 201 is closed after adding;
during detection, firstly, a detection head of an alcohol testing instrument is inserted into the insertion tube 202, then the air pump 3 is started and the electromagnet 163 is electrified, after the electromagnet 163 is electrified, the magnetism of the electromagnet is the same as that of the locking shaft 165, so that the locking shaft 165 is pushed upwards out of the locking groove 164, at the moment, the fixing shaft 801 is separated from the lifting shaft 802, the air pump 3 pumps outside air into the connecting tube 5 through the air inlet tube 4, then the air enters the bottom box 6 through the connecting tube 5, the air entering the bottom box 6 pushes the first blades 7 to rotate, so that the fixing shaft 801 is driven to rotate, at the moment, the air outlet tube 12 is in a closed state, the soaking tube 13 is in an open state, the air rotating in the bottom box 6 enters the detection box 1 through the soaking tube 13 and enters alcohol, bubbles are formed in the alcohol, the bubbles can overflow upwards in the alcohol, the bubbles are in contact with the alcohol, when the bubbles overflow the alcohol, the gaseous alcohol contained in the gas flow flowing out of the alcohol can be enabled to be not held under the partition plate 14, when the pressure under the partition plate 14 reaches the opening pressure of the pressure valve pipe 15, the gas containing the gaseous alcohol under the partition plate 14 enters the upper part of the partition plate 14 through the pressure valve pipe 15 to be mixed with the air above the partition plate 14, and the alcohol concentration above the partition plate 14 is continuously increased along with the continuous entering of the gas containing the gaseous alcohol, so that the maximum detection concentration of an alcohol testing instrument is achieved;
then, the alcohol testing instrument is started, then the electromagnet 163 is powered off, at the moment, the lifting shaft 802 moves downwards under the action of gravity, the locking shaft 165 is inserted into the locking groove 164, at the moment, the fixing shaft 801 drives the lifting shaft 802 to rotate when rotating, so that the second blade 9 is driven to rotate, the second blade 9 sucks outside air into a space above the partition plate 14 through the communicating air pipe 11 and the air feeding pipe 23 when rotating, because the rotating speeds of the second blade 9 and the first blade 7 are the same, the diameter values of the air feeding pipe 23 and the soaking pipe 13 are the same, the air quantity and the gaseous alcohol quantity entering the space above the partition plate 14 are the same, and at the moment, the maximum concentration detection is carried out on the alcohol testing instrument;
after the detection is qualified, the soaking pipe 13 is closed, the air outlet pipe 12 is opened, at the moment, the gas is stopped being introduced into the alcohol, so that the alcohol content in the space above the partition plate 14 is unchanged, the air content is rotationally sucked into the space above the partition plate 14 through the pair of blades two 9, the alcohol concentration above the partition plate 14 is continuously reduced, when the alcohol concentration reaches the next detection concentration, the air outlet pipe 12 is closed, the soaking pipe 13 is opened, the alcohol concentration above the partition plate 14 is stabilized, and the second concentration detection is realized;
repeating the steps, continuously reducing the detection concentration of the alcohol testing instrument, and completely detecting, wherein if any detection result is inconsistent with the alcohol content concentration, the alcohol testing instrument is unqualified;
when detecting, fixed axle 801 drives floating plate 19 through driving spout 21 and slider 22 and rotates, because floating plate 19 can be with floating on the liquid level of alcohol, when alcohol constantly consumes, floating plate 19 moves down along with the less of alcohol content, when the bottom surface contact of rubbing strip 20 with detection case 1 inner chamber, rubbing strip 20 rubs with detection case 1 inner chamber bottom surface, because rubbing strip 20 is ceramic material, can produce the sound of sand and sand when the friction, operating personnel can judge the content of alcohol through sound, thereby in time add alcohol.
