The invention discloses an automatic rotating
sprayer which comprises a
stator, a rotating head rotationally connected to the
stator, and at least one power slit. The rotating head is provided with a fluid cavity, at least one fluid inlet and multiple fluid outlets, wherein the fluid inlet and the fluid outlets communicate with the fluid cavity. The power slits are arranged on the rotating head and communicate with the fluid cavity, the
projection line, on the longitudinal projection face, of the axis of the power slit does not coincide with the
projection line, on the longitudinal projection face, of the axis in the height direction of the rotating head, so that when a solution in the fluid cavity is sprayed out from the power slit,
impact force is generated on the rotating head and is then converted into torque driving the rotating head to rotate, the solution is in the shape of
fog curtains when sprayed out from the power slit, the
fog curtains can be better atomized under the rotation of the rotating head, and therefore the atomization effect of the
sprayer is improved, and the weight of the
sprayer is reduced; and meanwhile, the resistance exerted on the solution is low when the solution is sprayed out of the power slit, relatively small
kinetic energy is lost, and the injection range of the atomized solution is longer.
