An air-conductive rotary sprinkler includes an air-conductive rotary sprinkling device and an air/fluid supply assembly. The air-conductive rotary sprinkling device further includes a main housing tube, an inner rotary tube and a rotary spray head. The rotary spray head includes a spray-head casing
An air-conductive rotary sprinkler includes an air-conductive rotary sprinkling device and an air/fluid supply assembly. The air-conductive rotary sprinkling device further includes a main housing tube, an inner rotary tube and a rotary spray head. The rotary spray head includes a spray-head casing connected with the inner rotary tube and a guide plug installed inside the spray-head casing and further including a helical actuating groove, a helical conductive groove, a central channel and a sideway channel. The fluid in the fluid-conveying pipe can be sprayed along the base axis by the pressured airflow from the central channel, the rotary spray head is rotated by the pressured airflow from the helical air channel, the spray direction of the fluid originally flowing along the base axis is altered by the pressured airflow from the helical conductive channel so as to spray out of the rotary spray head in a rotary manner.

1. An air-conductive rotary sprinkling device, connected with an air/fluid supply assembly having a spray gun for providing a pressured airflow and a fluid supply apparatus for providing a fluid through a fluid-conveying pipe, comprising: a main housing tube, connected with the air/fluid supply asse
1. An air-conductive rotary sprinkling device, connected with an air/fluid supply assembly having a spray gun for providing a pressured airflow and a fluid supply apparatus for providing a fluid through a fluid-conveying pipe, comprising: a main housing tube, connected with the air/fluid supply assembly;an inner rotary tube, rotationally mounted inside the main housing tube about a base axis, having an air-conveying channel for introducing the pressured airflow, the fluid-conveying pipe penetrating the air-conveying channel; anda rotary spray head, including: a spray-head casing, connected with the inner rotary tube, having an accommodation room communicative in space with the air-conveying channel; anda guide plug, installed inside the accommodation room, including: a helical actuating groove, pairing an inner wall of the spray-head casing to form a helical air channel communicative in space with the air-conveying channel so as to provide the pressured airflow to rotate the rotary spray head;a helical conductive groove, located symmetrically with respect to the helical actuating groove, pairing another inner wall of the spray-head casing to form a helical conductive channel communicative in space with the air-conveying channel;a central channel, extending along the base axis and being communicative in space with the air-conveying channel, the fluid-conveying pipe penetrating the central channel so as to have the fluid flowing out thereof to be driven by the pressured airflow injected from the central channel and thus to be sprayed out thereof along the base axis; anda sideway channel, extending along an air-injection direction crossing the base axis and being communicative in space with the helical conductive groove, providing the pressured airflow to alter the spray direction of the fluid originally flowing along the base axis;wherein, by providing the pressured airflow to rotate the rotary spray head and to alter the spray direction of the fluid flowing originally along the base axis, the fluid is sprayed out of the rotary spray head in a rotary manner. 2. The air-conductive rotary sprinkling device of claim 1, further including a bearing having an inner ring sleeved onto the inner rotary tube and an outer ring sleeved into the main housing tube. 3. The air-conductive rotary sprinkling device of claim 1, further including an extension tube and a guide pipe, in which the extension tube is connected with the main housing tube and the air/fluid supply assembly, the guide pipe connected with the extension tube penetrates the inner rotary tube, and the guide pipe allows the fluid-conveying pipe to penetrate. 4. The air-conductive rotary sprinkling device of claim 1, further including a brush assembly sleeved onto the main housing tube. 5. An air-conductive rotary sprinkler, comprising: an air-conductive rotary sprinkling device, including: a main housing tube;an inner rotary tube, rotationally mounted inside the main housing tube about a base axis, having an air-conveying channel; anda rotary spray head, including: a spray-head casing, connected with the inner rotary tube, having an accommodation room communicative in space with the air-conveying channel; anda guide plug, installed inside the accommodation room, including: a helical actuating groove, pairing an inner wall of the spray-head casing to form a helical air channel communicative in space with the air-conveying channel;a helical conductive groove, located symmetrically with respect to the helical actuating groove, pairing another inner wall of the spray-head casing to form a helical conductive channel communicative in space with the air-conveying channel;a central channel, extending along the base axis and being communicative in space with the air-conveying channel; anda sideway channel, extending along an air-injection direction crossing the base axis and being communicative in space with the helical conductive groove; andan air/fluid supply assembly, including: a spray gun, engaging the main housing tube for providing a pressured airflow into the air-conveying channel; anda fluid supply apparatus, connected with the spray gun, having a fluid-conveying pipe penetrating the air-conveying channel and the central channel;wherein the fluid in the fluid-conveying pipe flowing out is driven to spray out of the fluid-conveying pipe along the base axis by the pressured airflow injected from the central channel, the rotary spray head is driven to rotate by the pressured airflow injected from the helical air channel, the spray direction of the fluid flowing originally along the base axis is altered by the pressured airflow injected from the helical conductive channel, and thus the fluid is sprayed out of the rotary spray head in a rotary manner. 6. The air-conductive rotary sprinkler of claim 5, wherein the air-conductive rotary sprinkling device further includes a bearing having an inner ring sleeved onto the inner rotary tube and an outer ring sleeved into the main housing tube. 7. The air-conductive rotary sprinkler of claim 5, wherein the air-conductive rotary sprinkling device further includes an extension tube and a guide pipe, in which the extension tube is connected with the main housing tube and the air/fluid supply assembly, the guide pipe connected with the extension tube penetrates the inner rotary tube, and the guide pipe allows the fluid-conveying pipe to penetrate. 8. The air-conductive rotary sprinkler of claim 5, wherein the air-conductive rotary sprinkling device further includes a brush assembly sleeved onto the main housing tube.
