An automatic rotary nozzle

Abstract

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.

Description

technical field [0001] The invention relates to the field of atomization technology, in particular to an automatic rotating nozzle. Background technique [0002] The structure of the commonly used atomizing nozzle in the prior art mainly includes a fixed nozzle body. The nozzle body has a spiral fluid chamber inside, and the nozzle installed at the outlet of the nozzle body. Atomized under the action of centrifugal force and sprayed out through the nozzle. However, for the nozzle with this structure, when the fluid rotates in the fluid chamber, most of its kinetic energy is absorbed by the nozzle body, which reduces the atomization kinetic energy of the nozzle and shortens the atomization distance. [0003] Chinese patent document CN104741258A discloses an atomizing nozzle, including a rotating head with a smooth outer wall, a direct-injection fan nozzle arranged on the end of the rotating head, a wide-angle power nozzle symmetrically arranged on both radial sides of the ro...
