[0026] As shown in Figure 1 and Figure 2 The utility model discloses a crucible tray, including shell 1 and board cover 2, shell 1 has the accommodating cavity 11 and the opening 12 that communicates with the accommodating cavity 11, board cover 2 can be detachably connected to shell 1 to cover opening 12, board cover 2 is equipped with a plurality of for placing the placing hole 21 of crucible 3, wherein, the material of shell 1 and the material of board cover 2 are all heat insulation materials. Specifically, the heat insulation material needs to have the performance of low thermal conductivity to realize its heat insulation function and avoid the scald caused by the direct contact of human hands. At the same time, the heat insulation material needs to have certain high-temperature resistance and structural strength to avoid damage to the placed crucible. In the embodiment, the heat insulation material includes but is not limited to ceramic, stone and enamel and the like. More specifically, the material of shell 1 is preferably enamel. The material of board cover 2 is preferably ceramic. Specifically, the accommodating cavity can provide a certain placing space for the bottom of the crucible, facilitating the placement of the crucible. At the same time, the design of the accommodating cavity can avoid the contact between the crucible on board cover 2 and shell 1, thereby avoiding the rapid conduction of the heat of the crucible in the high-temperature state to shell 1, thereby achieving the heat insulation effect and avoiding the scald caused by the contact of human hands with shell 1.
