Description

Technical Field

[0001] The utility model belongs to the technical field of photometers, and in particular relates to an infrared spectrophotometer. Background Art

[0002] Chinese patent application number 202221783215.1 discloses an infrared spectrophotometer. By rotating a rotating baffle, the rotating baffle does not block the dust screen. Then, by rotating the dust screen, the surface of the dust screen is brought into contact with a cleaning brush. The dust screen is opened more conveniently, so that the components inside the infrared spectrophotometer can be maintained. The movement of the cleaning brush is controlled by rotating a rotating handle, and the cleaning brush brushes the surface of the dust screen. The position of the insertion rod can be controlled by pressing a pressure plate. After the insertion rod leaves the inside of the socket, the cleaning brush is rotated so that the cleaning brush as a whole can be located closer to the infrared spectrophotometer body.

[0003] However, most existing infrared spectrophotometers need to be used in conjunction with computers and other control devices. Some existing photometers and control devices are mostly separate structures, which requires workers to move back and forth between the two devices to place filters and adjust parameters. The control devices on some integrated photometers are mostly fixed at an angle, which makes it difficult for different workers to adjust the angle of the control devices to a comfortable position, resulting in poor practicality.
