Abstract
A vacuum evaporation device and system comprises a material container and a recycling structure, wherein a nozzle is arranged on the upper end surface of the material container; the recycling structure is arranged around the nozzle; and the recycling structure is configured to receive material when the material sprayed from the nozzle is fallen down. By arranging the recycling structure, the deposited material is received when it is fallen down, so that the nozzle is prevented from being clogged by the fallen material.
