The outer side walls of the adjacent ends of the first mounting seat 120 and the second mounting seat 130 are respectively provided with a first mounting step 210 and a second mounting step 320. The first mounting step 210 and the second mounting step 320 together constitute a mounting groove 410, and a sealing strip 170 is provided in the mounting groove 410.

[0042] A second annular groove 220 that cooperates with the baffle 930 is provided on the inner side wall of the installation cavity. The first mounting seat 120 and the second mounting seat 130 are combined to form a complete iodine liquid cavity 5950, an installation cavity, a first through hole 5910, a second through hole 570, a third through hole 540, a fourth through hole 550 and a second annular groove 220.

[0043] Through the arrangement of the device body 110, the cylindrical sliding cavity 510, the iodine liquid cavity 5950, the installation cavity, the rice holding dish, the air pump 560 and the extrusion mechanism in the present embodiment, when identifying the rice variety, the staff only needs to put the rice into the rice holding dish and then start the air pump 560. When the air pump 560 pulls the rice holding dish to move downward in the cylindrical sliding cavity 510, the atmospheric pressure in the iodine liquid cavity 5950 and the installation cavity increases, thereby the iodine liquid in the iodine liquid cavity 5950 is pressed into the rice holding dish to soak the rice. When the rice holding dish descends to a certain depth, the air pump 560 pushes the rice holding dish to move upward. At this time, the atmospheric pressure in the installation cavity decreases, thereby causing the extrusion mechanism in the installation cavity to move downward. The clean water in the installation cavity is pressed into the rice holding dish to wash the rice. After the washing is completed, the color of the rice is observed to determine the rice variety, which is convenient for the staff to quickly identify the rice variety. At the same time, the whole detection process is completed automatically without the need for the staff to do it themselves, which improves the work efficiency of the staff. During the detection process, the device body 110 can better control the amount of iodine solution and clean water added through atmospheric pressure, thereby better improving the accuracy of the detection. At the same time, the air pump 560 can control the time for the rice holding dish to descend in the cylindrical sliding cavity 510, so that the iodine solution can completely react with the substances in the rice before the clean water is added to the rice holding dish, thereby better facilitating the staff's subsequent observation.

[0044] By means of the first through hole 5910, the second through hole 570, the plastic tube 590, the one-way valve 5920, the baffle 930, the water storage chamber 5930, the air pressure chamber 5940, the third through hole 540, the fourth through hole 550, the extrusion plate 910, the sliding rod 920, the first hose 580 and the second hose 520 in this embodiment, the rice holding dish moves downward, and the air in the cylindrical sliding chamber 510 is compressed and discharged from the first through hole 5910 and the fourth through hole 550. 50 enters the iodine liquid chamber 5950 and the air pressure chamber 5940 respectively, the air pressure in the iodine liquid chamber 5950 and the air pressure chamber 5940 increases, the extrusion plate 910 in the air pressure chamber 5940 moves up and pushes the sliding rod 920 and the extrusion plate 910 in the water storage chamber 5930 to move up, the air pressure in the iodine liquid chamber 5950 increases, and the iodine liquid enters the first hose 580 and the rice holding dish from the second through hole 570 to soak the rice. When the rice holding dish moves down through the first through hole 5910, the iodine The air pressure in the liquid chamber 5950 does not increase, and the addition of iodine liquid to the rice holding dish stops. When the rice holding dish drops to a certain depth, the air pump 560 pushes the rice holding dish upward. During the upward movement of the rice holding dish, the air pressure in the air pressure chamber 5940 decreases. Under the push of the atmospheric pressure and the spring 530, the squeezing plate 910 in the air pressure chamber 5940 moves downward, thereby driving the squeezing plate 910 in the water storage chamber 5930 to move downward, thereby the water storage chamber 5930 is filled with water by the atmospheric pressure. The clean water in the iodine liquid chamber 5950 is pressed into the rice holding dish to dilute the iodine solution and wash the rice, thereby controlling the amount of iodine solution and clean water added, thereby better improving the accuracy of detection; at the same time, after the rice holding dish moves up and passes through the first through hole 5910, since a one-way valve 5920 is provided in the third through hole 540, it is better to prevent the air pressure in the iodine liquid chamber 5950 from decreasing during the upward movement of the rice holding dish, and the atmospheric pressure presses the iodine liquid in the first hose 580 back into the iodine liquid chamber 5950.

[0048] By setting the spring 530 in this embodiment, when the rice holding dish moves upward, the air pressure in the air pressure chamber 5940 decreases, and the spring 530 pushes the extrusion plate 910 in the air pressure chamber 5940 to move downward, thereby driving the extrusion plate 910 in the water storage chamber 5930 to move downward, thereby better facilitating the pressing of the clean water in the water storage chamber 5930 into the rice holding dish.

[0049] By configuring the open receiving seat 610, the funnel net 810 and the conduit 710 in this embodiment, the rice is placed in the funnel net 810, and the iodine solution and the clean water flow into the open receiving seat 610 from the two conduits 710 respectively, and the funnel net 810 can be taken out from the open receiving seat 610, thereby making it more convenient for the staff to take out the rice for observation.
