The slide plate is used for shielding the detection cavity during detection, so that external light cannot enter the detection cavity. At this time, even the radian of the kettle to be measured is not identical with the radian of the measuring head, the measuring head is not completely attached to the side wall of the kettle during detection, and the color measurement can be realized at this time as the detection cavity is a black cavity without light leakage, so that the color measurement result is not influenced.

In some embodiments, a flexible material (such as sponge) may be disposed on the periphery of the probe 4, so as to buffer the probe and the sample to be measured. Even if the outer shape radian of the actual sample to be measured is not identical to the radian of the measuring head 4, color measurement can be realized. To avoid influencing the detection result, the flexible material should generally be black.

When the table-type color measuring instrument is used, the detection cavity 3 is covered by the sliding plate 6 in a normal state, the upper end part of the longitudinal sliding block 11 moves into the detection cavity 3, the sliding plate 6 is firstly shifted upwards, the positioning sliding block 7 is adsorbed on the upper top of the longitudinal sliding groove 101, then the kettle 5 is placed into the detection cavity 3, when the positioning sliding block 7 touches the longitudinal sliding block 11, the adjusting block 9 is pulled outwards, the transverse sliding block 8 is separated from the longitudinal sliding block 11, at the moment, the longitudinal sliding block 11 falls back into the placing groove 103, then the kettle 5 is continuously pushed to the other end of the detection cavity 3, when the positioning sliding block is positioned on the lower side of the measuring head 4 and the upper side of the longitudinal sliding block 11, the adjusting block 9 is released, the tension spring 10 enables the transverse sliding block 8 to move towards the inner side of the adjusting groove 102 and enables the longitudinal sliding block 11 to be pushed out of the placing groove 103 to be abutted against the lower surface of the kettle 5 in the detection cavity 3, the sliding plate 6 is shifted again, finally, the detection cavity 3 is covered up, the touch operation is performed through the touch screen 2, the color difference detection of the kettle 5 in the detection cavity 3 is detected by the using the measuring head 4, and the electric kettle detection accuracy is reduced, and at the same time, the detection accuracy of the electric kettle detection is improved.
