[0002] The crystal furnace device is an important experimental device in quantum optics experiments and laser device experiments. It is used to install and place nonlinear crystals or laser crystals.

[0003] Chinese patent publication number CN218812254U discloses a crystal furnace temperature control device. Its technical solution includes: an outer shell, an inner wall of which is mounted a thermal insulation layer, an inner wall of which is mounted an explosion-proof layer, the inner wall of which is connected to an explosion-proof inner shell via a buffer mechanism, a cavity disposed between the outer wall of the explosion-proof inner shell and the inner wall of the explosion-proof layer, an electric heating coil disposed within the cavity, a temperature detection sensor disposed at the top end of the explosion-proof inner shell, the buffer mechanism comprising a first connecting post, a connecting plate, a spring, a mounting hole, a second connecting post, a bump, a damping rubber pad, and a strip slot, the center of the end wall of the second connecting post having a mounting hole disposed therein, a spring mounted within the mounting hole. This utility model not only facilitates temperature control within the crystal furnace, but also effectively provides explosion protection, improving safety and enhancing practicality.

[0004] When the crystal furnace of the above patent is heated, fewer flame holes are set. In order to facilitate installation, the flame holes are generally set on the ignition device below the crystal furnace facing the upper surface of the crystal furnace. The temperature of the setting position of such flame holes starts to rise along the bottom of the melting pot and spreads upward, which makes it difficult to control the temperature in the crystal furnace. If the melting pot is made of different materials, the temperature conduction speed will also be different. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem that in the prior art, when the crystal furnace is heated, the number of flame holes is small, and for the sake of installation convenience, the flame holes are generally arranged on the ignition device below the crystal furnace directly facing the upper surface of the crystal furnace. However, the temperature of the flame holes at this location starts to rise along the bottom of the melting kettle and spreads upward, making it difficult to control the temperature inside the crystal furnace. Since the melting kettle is made of different materials, the temperature conduction speed is also different, this embodiment provides the following technical solutions:
