Abstract
A spray device includes a converging assembly, a container and a suction pipe. The converging assembly includes a first liquid channel, a second liquid channel, a first air channel and a second air channel. The first liquid channel and the first air channel communicate with an inlet of the second liquid channel. The second air channel communicates with the container. An end of the suction pipe communicates with the inlet of the second liquid channel, and another end is submerged in a solution in the container. When a liquid flows from the first liquid channel to the second liquid channel, air in the first liquid channel is discharged via the first air channel, the solution is sucked to the second liquid channel through the suction pipe, the solution and the liquid are mixed at the inlet of the second liquid channel, and then are sprayed from the second liquid channel.
