Rotary spraying device

摘要

Disclosed is a rotary spraying device in which a fluid tube is assembled with a rotary means formed to have a channel structure. A portion of a fluid which flows through the fluid tube flows into the rotary means so as to provide a rotation applying force for rotating the rotary means when the fluid flows through the channel structure in the rotary means. Thus, the fluid is sprayed rotatably from the fluid tube which is rotated with the rotary means.

主权项

1. A rotary spraying device comprising:
a fluid tube for a first fluid flowing therein, and provided at one end thereof with a fluid inlet for entry of the first fluid and the other end thereof with a spraying outlet, a through hole provided on a tube wall of the fluid tube; a rotary means, coupled with the fluid tube, and forming a drive wall therein facing and inclining toward the through hole and an outflow passage formed at an end of the drive wall, a flow space formed between the through hole, the outflow passage and the drive wall, and the first fluid flowing within the flow space from the through hole toward the drive wall along a flowing direction of the first fluid away from the fluid tube and orthogonal to a tube-extending direction of the fluid tube; a conveying tube provided at one end thereof with a fluid container inlet for connecting to a fluid container having a second fluid received therein, and an end portion of the conveying tube being disposed within the fluid tube to extend to the spraying outlet of the fluid tube so that the second fluid is conveyed toward the spraying outlet; and a rotation speed adjusting means including a first adjusting member and a second adjusting member, wherein the first adjusting member is connected with the outflow passage of the rotary means and has an outlet surface formed with a plurality of first openings and the second adjusting member has an inlet surface coupled with the outlet surface of the first adjusting member to be rotatable relative to the first adjusting member, and the inlet surface is formed with a plurality of second openings corresponding to the plurality of first openings; wherein the first fluid flows between the fluid tube and the conveying tube from the fluid inlet toward the spraying outlet, and further flows into the rotary means through the through hole to drive the rotary means to rotate when the first fluid engages with the drive wall of the rotary means along the flowing direction thereof, the fluid tube is rotated along with the rotary means to rotationally spray the second fluid of the fluid container out of the rotary spraying device at the spraying outlet.
