Abstract:
1. A miniature sieve, comprising: a first plate having a plurality of first sieves that are regularly arranged in a matrix, wherein each of the first sieves has at least one first mesh; a second plate stacked on a side of the first plate and having a plurality of separators that are regularly arranged in a matrix, wherein the separators are aligned with the first sieves, respectively, and each of the separators has a separation hole; a third plate stacked on a side of the second plate opposite to the first plate and having a plurality of second sieves that are regularly arranged in a matrix, wherein each of the plurality of second sieves has a plurality of second meshes, such that the number of second meshes in the plurality of second sieves is greater than the number of first meshes in the plurality of first sieves, wherein the second sieves are aligned with the separators, respectively, so that a sieve unit is formed by one of the plurality of first sieves along with one of the corresponding separators and one of the plurality of second sieves such that the miniature sieve has a plurality of sieve units; wherein the at least one first mesh in each of the plurality of first sieves and the plurality of second meshes in each of the plurality of second sieves are misaligned with each other in a vertical direction of the aligned first and second sieves; the diameter of the plurality of second meshes is smaller than that of the first mesh.
