When the vehicle is running, external air flow flows through the inner side of outer barrel 1 and turbofan 2 is produced rotation, when car speed is relatively low, gas The insufficient pressure formed when stream flows through turbofan 2 to turbofan 2 is to overcome the pulling force of extension spring 4, and turbofan frame 2 remains stationary as, therefore turbofan 2 Do not contacted with inner cylinder 3, turbofan 2 individually rotates；
With the increase of speed, increasing therewith by the air velocity of the inner side of outer barrel 1 makes the velocity of rotation of turbofan 2 constantly accelerate, Meanwhile the pressure that is formed to turbofan 2 of the air-flow after speed increase gradually increases and overcomes the pulling force of extension spring 4 to make turbofan 2 to moving to left Dynamic, turbofan frame 2 is simultaneously mobile with turbofan 2 and drives sliding bar 19 to be slided on outer barrel 1 through gusset 20, and sliding bar 19 slides to the left When, spring 10 is compressed and its elastic force gradually overcomes the frictional force between curved baffle 6 and outer barrel 1 to be promoted curved baffle 6 And slide to the left, the first air outlet 7 produces overlapping with the second air outlet 8, and air-flow enters through the first air outlet 7 and the second air outlet 8 Enter in-car；
When the first air outlet 7 and completely overlapped the second air outlet 8, inlet channel is opened completely, now because spring 10 can be after It is continuous to be compressed, therefore with the increase of speed, gas-flow resistance promotes whirlpool after gradually overcoming the pulling force of extension spring 4 and the elastic force of spring 10 Fan 2 continues mobile to the direction of inner cylinder 3 and extrudes inner cylinder 3, turbofan 2 extrude inner cylinder 3 make frictional force between turbofan 2 and inner cylinder 3 by Cumulative big, inner cylinder 3 beginning rotation and rotating speed on retainer plate 9 under frictional force effect gradually increase to consistent with the rotating speed of turbofan 2； Inner cylinder 3 drives flabellum 5 to rotate simultaneously, and the air-flow flowed through between outer barrel 1 and inner cylinder 3 is blowed to in-car by flabellum 5.
With the further increase of speed, the air velocity constantly increase of the inner side of outer barrel 1 and the rotation formation one to fan Fixed interference, fan is blown into the air-flow of in-car and reduce, now because gas-flow resistance further increases, turbofan 2 promotes inner cylinder 3 outside The reverse slide advanced on cylinder 1 to vehicle, the rotating cylinder 13 contacted with inner cylinder 3 produce under the promotion of inner cylinder 3 in fixed cylinder 11 Slide, and due to the effect of ball 23, the frictional force between inner cylinder 3 and rotating cylinder 13 is smaller, and rotating cylinder 13 will not be to the rotation of inner cylinder 3 Produce larger resistance；When rotating cylinder 3 is sliding in fixed cylinder 11 to rear view of vehicle, rotating cylinder 13 is in radial bars 15 and cam path 16 The rotation in fixed cylinder 11 is produced under guiding function, the concomitant rotation of longitudinal baffle 17 simultaneously gradually leans on to the direction of connecting plate 12 Closely, the distance between longitudinal baffle 17 and connecting plate 12 and angle produce change, make by the air-flow between connecting plate 12 by To the stop of longitudinal baffle 17, as the distance between longitudinal baffle 17 and connecting plate 12 constantly diminish, while longitudinal baffle 17 Dislocation angle between connecting plate 12 constantly becomes big, and increasing air-flow is blocked between outer barrel 1 and inner cylinder 3, and by Fan is blown into in-car, intake is increased again, reaches preferable ventilation effect；When rotating cylinder 13 is driven fully into fixed cylinder 11 Afterwards, rotating cylinder 13 reaches 1/2 of the angle between the i.e. two neighboring connecting plate 12 of maximum rotation angle in fixed cylinder 11, and this When longitudinal baffle 17 be moved to rotating cylinder 13 and contacted with connecting plate 12 and be placed in two adjacent connecting plates 12 between, outer barrel 1 with Air-flow between inner cylinder 3 is blocked fully, in the presence of the pressure and fan in air current flow, between outer barrel 1 and inner cylinder 3 Air-flow is forced into in-car, reaches full admission state.
In order that the present invention reaches more preferable ventilation effect, outer barrel 1 can be lengthened and be added in one end where turbofan 2 Air filter screen is filled, the particulate matters such as the pollen in air can not only be filtered, after air-flow can also be made fully to cool in outer barrel 1 In-car is entered back into, in-car air is kept more comfortable state.
Clever structure of the present invention, it is simple to operate, drive turbofan to rotate using external air flow, and then fan running is driven, and Air outlet is automatically turned on, realizes the ventilation operation of vehicle, when speed is higher, also promotes rotating cylinder to open using gas-flow resistance Longitudinal baffle realizes that the stop to air-flow makes more air-flows into the car；Because external air flow need to be after passing through fan again by fan It is blown into, rather than is directly blown into vehicle interior, therefore the present invention compares with directly windowing ventilation and is blown into speed with wind small, air-flow of making an uproar The characteristics of degree is stable, simultaneously because outer barrel can ensure the unimpeded of air-flow with inner cylinder, it is controllable to the blocking effect of air-flow, therefore row Caused windage is smaller during car, will not increase excessive oil consumption and carry out offset resistance, the reduction for oil consumption serves very Good gain effect.
In addition, the present invention makes turbofan frame to be slided on outer barrel using the pulling force of extension spring, and when low vehicle speeds, fan Do not contacted with turbofan, fan is inoperative, and the influence now travelled to vehicle by windage is smaller, therefore can open air outlet by row Natural airflow when sailing realizes that the air-flow inside and outside vehicle exchanges, or windowing ventilation as needed, can equally meet use demand；When During high vehicle speeds, air drag overcomes tension spring tension, and turbofan contacts with fan and drives fan running, by more air-flows In-car is blown into, and avoids the need for the worry of windowing ventilation；Meanwhile separating turbofan with inner cylinder makes fan meet specific speed Under the conditions of another gain effect for working be that fan will not be operated uninterruptedly, effectively reduce the abrasion of fan, improve use Life-span.
