Abstract
A spray gun for a cleaning device and a cleaning device. The spray gun comprises: a valve assembly (2), a first trigger (3), and a second trigger (4), wherein a lever arm between a first resistance part of the first trigger (3) and a first fulcrum part (1p1) is smaller than a lever arm between a first force application part and the first fulcrum part (1p1), and a lever arm between a second resistance part of the second trigger (4) and a second fulcrum part (1p2) is smaller than a lever arm between a second force application part and the second fulcrum part (1p2). The second trigger takes the part connected to the first trigger as the second resistance part, so that the first trigger and the second trigger form a two-stage compound labor-saving lever structure, and the pressing states of the two triggers of the spray gun can be kept with small driving force.
