[0016] 2. By setting an auxiliary piston member, when the first connecting sleeve drives the first piston block to move upward to suck the air and atomized fuel inside the auxiliary sleeve into the second piston sleeve, the second spur gear is driven upward by the rectangular slider, thereby driving the spur gear to rotate, and then driving the first spur gear to drive the rectangular slide bar to move downward, so that the second piston block pushes the air and atomized fuel inside the first piston sleeve into the auxiliary sleeve, and the air and atomized fuel inside the auxiliary sleeve are constantly creeping, thereby further improving the mixing effect of the air and atomized fuel;
