Although the above-mentioned patent can solve the problem of clamping and fixing diamonds of different sizes, some diamond growth chambers in the existing technology are difficult to filter the reaction gas. There are a large amount of impurities in the reaction gas, such as water vapor, dust, etc. These impurities will react with the carbon source in the growth process, resulting in a high content of oxygen, nitrogen and other impurities in the diamond crystal, reducing the purity and quality of the crystal. In addition, it is difficult to remove the filter plate, and the filter plate will produce residues or impurities. Regular cleaning and maintenance are important steps to ensure the cleanliness of the chamber and the growth quality. The difficult-to-remove structure will increase the complexity of the cleaning operation, resulting in incomplete cleaning or untimely maintenance, which in turn affects the growth quality. Therefore, in response to the above shortcomings, a single crystal diamond growth chamber mechanism is proposed. Summary of the Invention
