Powder particle size distribution measuring equipment, powder dispersing device, and method of measuring powder particle size distribution

A powder dispersing device of a powder particle size distribution measuring equipment, comprising:

• a base;
• an elastic force generating assembly mounted on the base, comprising:
• at least one bumping piece having one end and an other end,
• at least one force applying board having one end and an other end, and
• a power transmission assembly having one end connected to the one end of the bumping piece and the other end connected to the one end of the force applying board, wherein a first displacement applied to the force applying board enables the power transmission assembly to actuate the bumping piece to generate a second displacement which enables the bumping piece to have a first elastic force;
• and
• a first housing having one end coupled with the base and having a side surface formed with a through hole, wherein the elastic force generating assembly is covered inside the first housing and the other end of the force applying board extends out the through hole;
• wherein the first elastic force triggers the bumping piece to strike on a plane facing toward the inside of the first housing and touching the other end of the bumping piece.
