Abstract
A crucible. The crucible includes a crucible body having an opening formed at the top thereof. The crucible further includes a sealing cover and an elastic element. The sealing cover is configured to seal the crucible in a first position and open the crucible in a second position. In the first position, the sealing cover forms a detachable sealed connection with the crucible body. The elastic element is arranged between the sealing cover and the crucible body, where the elastic element is in a compressed state when the crucible is sealed by the sealing cover in the first position. Correspondingly, the present disclosure also provides an evaporation preparation device, evaporation equipment and an evaporation method. The present disclosure can reduce the deterioration of the material to be evaporated and the direct contact between human body and the material.
