During testing, the through hole of the conducting rod 11 is adjusted to be coaxial with the light-transmitting channel 13, and the micropore is communicated with the radiating hole, at this time, because the hot air pressure in the inner tube 2 is increased, the hot air is discharged into the heat exchange cavity 8, and under the action of the pressure spring 24, the air in the heat exchange cavity 8 cannot reversely enter the inner tube 2, the hot air in the heat exchange cavity 8 is discharged through the micropore through the radiating hole, namely, the air in the inner tube 2 expands and is discharged outwards in the testing process, and the outside air cannot enter the inner tube 2.
After the test is finished, the vertical horse closes the regulating wheel, the pressure intensity in the inner part can be reduced in the cooling process of the outer tube 1 and the inner tube 2, at the moment, the pressure difference can be regulated through the balance structure, the pressure intensity in the cooled inner tube 2 and the cooled outer tube 1 can be prevented from being reduced, the pressure difference can not be released due to the outside air pressure, the tightness of the inner tube 2 and the inner tube 1 is damaged, the outside dust enters the inner tube 2 and the inner tube 1, and the detection precision of the color difference meter 7 is reduced.
