Technical Field

[0002] Cultured diamonds are artificially grown diamonds that simulate the crystallization conditions and growth environment of natural diamonds. Both cultured diamonds and natural diamonds are crystals of pure carbon and have exactly the same physical and chemical properties. Compared with natural diamonds, cultured diamonds have the advantages of high cost performance, compliance with environmental protection trends, and a variety of styles. They are very consistent with the personalized needs of the new generation of consumers for light luxury and self-pleasure, and can greatly lower the purchase threshold for consumers. Diamond synthesis equipment is needed in the process of diamond synthesis.

[0003] The current diamond synthesis equipment has a slow synthesis efficiency and only has one synthesis process during synthesis. This synthesis process is not only very slow, but also causes temperature differences that affect the purity of the diamond. Therefore, the current diamond synthesis equipment cannot meet people's usage needs. Summary of the invention

[0008] A large-cavity diamond high-efficiency synthesis device using the technical solution uses a heating tube, a microwave generator, a methane tank and a hydrogen tank. The heating tube can heat the cavity of the synthesis mechanism. During heating, methane gas and hydrogen are respectively filled into the cavity of the synthesis mechanism through a first one-way gas filling tube and a second one-way gas filling tube. After the gas is filled, the microwave generator heats the diamond raw material. The HPTP method and the CVD chemical vapor deposition method are used simultaneously, thereby improving the synthesis efficiency of the device.

[0009] Furthermore, the synthetic structure includes a pressure transmission tube, a conductive plug, a conductive metal sheet, an inner lining tube, a thermal insulation layer, a heating tube and a microwave generator.

[0015] Furthermore, a synthesis method of a large-cavity diamond high-efficiency synthesis device comprises the following steps:

[0016] Step 1: Before diamond synthesis, the staff fills methane and hydrogen into the methane tank and hydrogen tank respectively through the first filling pipe and the second filling pipe. During the filling, the first barometer and the second barometer sense the air pressure in the methane tank and the hydrogen tank. When the methane tank and the hydrogen tank reach the appropriate air pressure, the filling is stopped;

[0017] Step 2: Then put the diamond raw material into the cavity of the synthesis mechanism, cover the synthesis mechanism tightly after putting it in, and then turn on the heating tube, the first one-way inflation tube, the second one-way inflation tube and the microwave generator through the control switch;

[0018] Step 3: The heating tube works to heat the cavity of the synthesis mechanism.
