Abstract
A vacuum generator may comprise: a generator body provided with an air inlet, a contraction pipe section, an expansion pipe section, a negative pressure generation cavity, and an air outlet that may be sequentially communicated, where in a ventilation direction from the air inlet to the air outlet, a pipe diameter of the contraction pipe section may be gradually decreased, a pipe diameter of the expansion pipe section may be gradually increased, and the negative pressure generation cavity may be constructed to generate an inner cavity jet flow negative pressure when gas ejected from the expansion pipe section flows through the negative pressure generation cavity; wherein the generator body may be further provided with a negative pressure suction flow channel, and the negative pressure suction flow channel may comprise a suction port section and a reduced-diameter flow channel section.
