[0027] 1. The body constituting the storage bin 102 and the working bin 101 in the present application is assembled between the connecting seat 10 and the cylinder structure made of metal material. Compared with injection molding plastic, the multi-section combination of metal material can withstand greater pressure. Metal material has high density, its internal atoms or ions are arranged more compactly, and the gap is smaller, which makes the cylinder structure and the connecting seat 10 have higher density, stronger hardness and better anti-deformation ability compared with the injection molding structure. The working bin 101 can be maintained in a high pressure state (greater than 28 psi).
