AI Technical Summary
In photocatalytic reactions, when sampling in a photocatalytic cabinet with high light intensity, the strong light reflected by the beaker is dazzling, making it difficult for experimenters to look directly, and traditional operating methods cannot fully observe the reaction beaker, which can easily lead to sample spilling and inconvenient operation.
A sampling and shielding device in the photocatalytic cabinet is designed, including a main light shielding hood and an auxiliary light shielding plate. The first and second sampling holes are arranged through the coordination of the lifting mechanism and the displacement guide rail to achieve double-layer light shielding of the reaction beaker to ensure that Adaptability and safety of sampling hole sets.

The reaction beaker is placed in the cabinet, and a strong light source is set directly above it. The strong light is directed downward on the beaker to catalyze the reaction of the substances in the beaker. In the actual reaction, multiple sampling is required to monitor the reaction process. Due to the extremely high light intensity, when the cabinet door is opened to take samples, the beaker reflects dazzling light, and the experimenter's eyes cannot look directly at the reaction beaker. Usually, only one side door of the outer box is opened to block light. When sampling, hide behind the left door and put the pipette gun into the beaker from the right side to take samples. Because the body stands on the left side, both hands need to take samples from the right half of the box door. However, the disadvantage of this operation is that the reaction beaker cannot be fully observed, which may cause the sample to spill, and the operation is also awkward. Summary of the invention

The light source 300 is placed directly in front of the reaction beaker 200. Before starting the catalytic reaction, the sampling position is simulated according to the actual size and placement of the beaker, and the appropriate first sampling hole 33 and second sampling hole 71 are selected as the sampling hole group. After starting the catalytic reaction, before opening the cabinet door of the photocatalytic cabinet 100 during sampling, the lifting mechanism 2 is controlled to drive the main shading cover 3 and the auxiliary shading plate 7 to descend to shield the reaction beaker 200, and the second displacement guide rail 5 drives the auxiliary shading plate 7 to move left and right to align the selected first sampling hole 33 and the second sampling hole 71. The experimenter opens the cabinet door and extends the sampling pipette from the sampling hole group into the reaction beaker 200 for sampling.
[0035] It is worth noting that there is no overlapping part between any two second sampling holes 71 in the vertical direction. The first sampling holes 33 are divided into several groups according to the positions of the second sampling holes 71 in the vertical direction. The first sampling holes 33 in each group are at the same position as the corresponding second sampling holes 71 in the vertical direction.

[0040] Preferably, the portions of the vertical plates of the main sunshade 3 located on the left and right sides are arc-shaped.
[0041] Preferably, the auxiliary shading plate 7 is tightly arranged on the front side of the vertical plate of the main shading cover 3 and the width of the left and right sides of the auxiliary shading plate 7 is greater than the second glass window 32, so as to prevent the auxiliary shading plate 7 from completely covering the remaining unselected first sampling holes 33 after aligning the sampling hole group.
