AI Technical Summary
Technical Problem
The existing flow cell is made of transparent plastic. After long-term use, the pore size increases, resulting in a decrease in particle counting accuracy.
Method used
The first and second shells are made of quartz diamond material, combined with a wear-resistant light-shielding layer and a plug-in structure to improve wear resistance and docking accuracy, and prevent the aperture from becoming larger.
Benefits of technology
It improves the stability and counting accuracy of the flow cell, ensuring that the aperture does not increase during use and maintaining high-precision counting.

Abstract
The utility model discloses a light-proof flow cell, and relates to the field of particle counter accessories, the light-proof flow cell comprises a first shell and a second shell, the first shell and the second shell are provided with flow holes, a wear-resistant light-proof layer is arranged between the first shell and the second shell, the second shell is provided with a plurality of first plugging holes, and the first plugging holes are communicated with the flow holes. And a plurality of corresponding first inserting columns are arranged in the plurality of first inserting holes. The first shell and the second shell are made of quartz diamond materials, the hardness of the first shell and the second shell is high, so that the parts making contact with detection liquid are made of the diamond materials, the wear resistance can be improved, the first inserting holes are formed in the four corners and matched with the first inserting columns, the butt joint precision is improved, and the detection accuracy is improved. Therefore, the grinding effect of the grinding liquid on the circulation hole can be effectively reduced, the phenomenon that the hole diameter of the circulation cell is increased can be avoided, the precision is not greatly influenced during counting, and the stability during use and the counting precision are improved.
