Description

Technical Field

[0001] The utility model relates to the technical field of optical paths of spectrometers, in particular to a bidirectional optical path observation mechanism for an ICP spectrometer. Background Art

[0002] When an ICP spectrometer performs optical path observation, it generally needs to observe the side and top areas of the flame area. The existing mechanism requires a set of observation eyepieces to be respectively provided on the side and top of the spectrometer. The two sets of observation eyepieces are independently provided on the opposite outer sides of the shell, and then the flame area is observed through the through hole on the shell. Since the observation eyepieces have a light source, two sets of observation eyepieces need to be provided in actual production, which increases the production cost of the entire ICP spectrometer. Moreover, the observation eyepiece provided on the top of the ICP spectrometer cannot be reliably observed by the operator. Therefore, it is urgent to develop a two-way optical path observation mechanism suitable for ICP spectrometers. Utility Model Content

[0003] In response to the above problems, the present invention provides a bidirectional optical path observation mechanism for an ICP spectrometer, which enables observation of two positions in the flame area by setting an observation eyepiece at a single position, reducing production costs and making observation convenient and quick.

[0008] and a top second reflector;

[0009] The top ends of the upper horizontal area are respectively provided with a first hypotenuse and a second hypotenuse, the first hypotenuse is installed with a top first reflector arranged at an angle of 45 degrees clockwise, and the second hypotenuse is installed with a top second reflector arranged at an angle of 45 degrees counterclockwise, the observation eyepiece is located on the outside of one side wall of the lower vertical area, the side wall of the lower vertical area away from the material combustion area is provided with an eyepiece observation hole, the other side wall of the lower vertical area close to the material combustion area is provided with an observation through hole, the height position of the observation through hole is equal to the height position of the material combustion area, and the lower wall of the shell is provided with a top observation through hole corresponding to directly above the material combustion area;

[0010] The first reflector has two states, and the rotating motor drives the first reflector to switch between the first state and the second state; in the first state, the horizontal light emitted from the eyepiece observation hole directly or indirectly passes through the observation through hole, thereby observing the side of the material combustion area; in the second state, the horizontal light emitted from the eyepiece observation hole passes through the top observation through hole from top to bottom after several reflections, thereby observing the top of the material combustion area.

[0011] It is further characterized by:

[0012] When the height of the eyepiece observation hole is equal to the observation through-hole, the rotating reflector assembly is located at a side position of the lower vertical area of ​​the inner cavity close to the material combustion area. In a first state, the first reflector is not on the propagation path of the horizontal light emitted from the eyepiece observation hole, and the horizontal light emitted from the eyepiece observation hole directly passes through the observation through-hole, thereby observing the side of the material combustion area.

The height of the third reflector is located on the propagation path of the horizontal light emitted from the eyepiece observation hole, and the rotating reflector assembly is located on the side of the lower vertical area of ​​the inner cavity away from the material combustion area. In the first state, the first reflector is on the propagation path of the horizontal light emitted from the eyepiece observation hole after passing through the third reflector.

After the horizontal light emitted from the eyepiece observation hole passes through the third reflector, the second reflector on the top, and the first reflector on the top, the light passes through the top observation through-hole from top to bottom, thereby observing the top of the material combustion area.

[0014] After adopting the above technical solution, by setting a first reflector that can switch between two position states in the inner cavity of the shell, and setting, the eyepiece observation hole with a fixed position can respectively observe the side of the material combustion area through the observation through hole, or observe the top of the material combustion area through the top observation through hole; it sets the observation eyepiece at a single position to observe two positions of the flame area, which reduces the production cost and makes observation convenient and quick.
