[0002] Crystal growth is the process of a substance forming a crystal from a gas phase, liquid phase or solid phase under specific physical and chemical conditions. The general process of crystal formation is to first generate a crystal nucleus and then gradually grow. It is generally believed that the growth of a crystal from a liquid phase or a gas phase has three stages: first, the medium reaches supersaturation and supercooling stage; second, the nucleation stage; and third, the growth stage.

[0003] The existing Chinese utility model patent "A continuous feeding device for crystal growth" with application number 202022356950.1 discloses that "the controller controls the valve 6 to open, so that the crystal growth solution in the liquid tank 5 is replenished to the reaction container 12 in time through the infusion tube 7, ensuring that the entire device can stably output high-quality crystals."

[0004] However, the above technical solution has the following problem: adding solution to the reaction container will generate bubbles. When the crystal nucleus is growing, the bubbles will cause the crystal to grow deformed, have holes or cracks, and affect the overall quality of the crystal. Utility Model Content
