Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

The air guide pipe of the embodiment of the invention comprises an outer pipe. The inner wall of the outer tube is provided with one or more closed cavities. An air outlet groove is arranged on the outer pipe (preferably along the length direction of the outer pipe). When the rotatable object rotates in the outer pipe, the closed cavity accumulates wind, when the rotatable object rotates to the wind outlet groove, the wind is discharged from the wind outlet groove, the accumulation-release circulation of wind power is realized, when the rotatable object rotates at high speed, the circulation frequency is also very high, and due to the flowing characteristic of the air, the generated air curtain has strong and weak circulation but is not interrupted. Preferably, the air guide pipe further comprises a driving mechanism which is connected with the rotatable object and drives the rotatable object to rotate. When the air guide pipe provided by the embodiment of the invention is used as a single pipe, the driving mechanism is arranged at one end of the outer pipe, and the other end of the outer pipe is sealed through an end cover.

In one embodiment, the driving mechanism is a wind wheel, and the rotatable object is an arc plate (a ventilation slot is formed between two ends of the arc plate). The wind wheel consists of blades and a hub.

Example 1 as an implementation, the rotatable object is an arc plate. As shown in fig. 1 to 3, the air guide duct according to the embodiment of the present invention includes an outer duct, a wind wheel, an arc plate, and an end cover. Wherein, the wind wheel comprises blade and wheel hub.

Wherein, wind wheel and arc board can be in the outer tube free rotation, and the during operation, the wind of external input is followed the wind wheel end input of outer tube, blows the blade of wind wheel, can drive wind wheel and arc board and rotate, shelters from out the wind groove at the arc board, and the outer tube can amass wind-force, and when the wind groove was sheltered from to the arc board, the wind-force of piling up in the outer tube released simultaneously on the length direction in whole wind groove.

The gap between the outer wall of the arc plate and the inner wall of the outer pipe is small, static air is carried between the pipe walls due to capillary action, under the condition that the wind wheel and the arc plate rotate at high speed, the outer pipe can accumulate wind power when the arc plate shields the air outlet groove, and air leaked between the outer wall of the arc plate and the inner wall of the outer pipe can be ignored; when the air outlet groove is not shielded by the arc plate, the wind power accumulated in the outer pipe is simultaneously released in the length direction of the whole air outlet groove, so that the circulation of accumulating the wind power and releasing the wind power is realized.

Example 2 as an embodiment, the rotatable object is a set of vanes constructed from a plurality of vanes circumferentially distributed about the axis of rotation. Preferably, the rotatable object further comprises a tab clip fixing the tabs of the tab set, the tab clip preventing the tabs of the tab set from being deformed. The end of the outer pipe connected with the driving mechanism is provided with a clapboard. The outer pipe is divided into two half areas of a wind accumulation area and a wind outlet area by the fin group and the partition plate. As shown in fig. 4 to 6, the air duct of the embodiment of the present invention includes a wind wheel, a vane group, a vane clip, an outer tube, a partition plate, an outer cover, an end cover, and a base. The wind wheel, the wing panel group and the wing panel clamp are combined into a whole, the partition plate is fixed on the outer pipe, and when the wind wheel is used, the blades on the wind wheel are blown by wind force to drive the wing panel group and the wing panel clamp to rotate together. In operation, the outer pipe is divided into two halves of a wind accumulation area and a wind outlet area by the wing group and the partition plate when viewed from the cross section of the outer pipe, and the accumulation-release circulation of wind power is realized by the rotation of the upper wing group. The outer cover is used for preventing dust, guiding wind and preventing liquid and insects from entering, and is opened when in use and closed when not in use. The base is used for supporting. The end caps are used for sealing.

Example 3 as an embodiment, the cross section of the outer tube is circular, square or other polygonal shape. When the cross section of part of the wing panel is in a curve shape, the wing panel is made of elastic materials and can deform when rotating in the outer tube. As shown in fig. 7 to 9, the air guide duct according to the embodiment of the present invention includes a wind wheel, a vane group, a vane clip, an outer tube, a partition plate, and an end cover. The wind wheel, the wing panel group and the wing panel clamp are combined into a whole, the partition plate is fixed on the outer pipe, and when the wind wheel is used, the blades on the wind wheel are blown by wind force to drive the wing panel group and the wing panel clamp to rotate together. The wind wheel, the vane group and the vane clamp are combined, the rotation axis does not coincide with the central line of the cross section of the outer pipe, in operation, the space enclosed by the vanes and the inner wall of the outer pipe is seen from the cross section of the outer pipe, and the vane group and the partition plate divide the inner space of the outer pipe into three parts, namely a wind accumulation area, a compression area and a wind outlet area. The lower part of the dotted line in fig. 9 is an air accumulation area, and along with the rotation of the vane group, the air in the accumulation area is rotated to the upper left corner of the hollow space in the outer pipe, and as the space is reduced, the volume of the air in the accumulation area is reduced, the pressure is increased, and when the vanes of the vane group are rotated to the air outlet groove, the air in the accumulation area is released. The air accumulation-compression-release cycle is realized.
