1. A powder atomic layer deposition equipment with a quick release function, comprising:
a driving unit;
a shaft sealing device connected to the driving unit; wherein the shaft sealing device comprises an outer tube and an inner tube, the outer tube including an accommodating space for accommodating the inner tube, and the inner tube including at least one connecting space;
a vacuum chamber connected to the shaft sealing device, and an enclosed space is formed between the vacuum chamber and the shaft sealing device, wherein the vacuum chamber includes a reaction space for accommodating a plurality of powders, and the driving unit rotates the vacuum chamber via the shaft sealing device;
at least one first seal ring and at least one second seal ring, located between the shaft sealing device and the vacuum chamber, wherein the enclosed space is located between the at least one first seal ring and the at least one second seal ring;
at least one first air extraction line, located in the shaft sealing device and fluidly connected to the enclosed space, wherein the at least one first air extraction line is used in pumping gas out from the enclosed space to fix the vacuum chamber to the shaft sealing device; and
at least one air intake line, located in the shaft sealing device and fluidly connected to the reaction space of the vacuum chamber, for delivering a precursor gas into the reaction space; wherein the at least one connecting space of the inner tube provided for accommodating the at least one first air extraction line and the at least one air intake line.
