[0047] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0048] First embodiment

[0049] Reference Figures 1 to 8The fan in this embodiment includes a first air outlet 10, a second air outlet 20 and a driving part 30. The first air outlet 10 includes a first base 11, and a plurality of first blades 12 are arranged on the edge of the first base 11. The second air outlet 20 includes a second base 21, and a plurality of second blades 22 are arranged on the edge of the second base 21. The windward surfaces of the first blades 12 and the second blades 22 are opposite to each other. The first blades 12 and the second blades 22 are alternately arranged in sequence along the axial direction of the first base 11 or the second base 21. The driving part 30 includes a rotor 31 and a stator 32. The stator 32 includes a plurality of winding groups 321. The rotor 31 is provided with a magnetic ring 311 on a side close to the stator 32. The rotor 31 is connected to the first air outlet 10 and / or the second air outlet 20 so that the first air outlet 10 and the second air outlet 20 can rotate relative to each other.

[0050] When the winding group 321 in the driving part 30 is energized, a magnetic field is generated, and the magnetic field interacts with the magnetic field generated by the magnetic ring 311, and the rotor 31 is inferred to rotate. During the rotation of the rotor 31, the first air outlet 10 and / or the second air outlet 20 are driven to rotate. The air can quickly enter from one side of the fan and be discharged from the other side of the fan after entering. The airflow has a short acceleration time, a large air volume and a high wind speed, and the air quality of the fan is optimized.

[0051] Preferably, the number of first blades 12 installed on the first substrate 11 is the same as the number of second blades 22 installed on the second substrate 21, and the first blades 12 and the second blades 22 correspond to each other along the axis direction of the first substrate 11 or the second substrate 21, and the first blades 12 and the second blades 22 can quickly connect with the airflow driven by the previous blade. Figure 6 As shown, along the direction from left to right, the odd-numbered positions are the first blades 12, and the even-numbered positions are the second blades 22. To ensure the air outlet effect of the fan, the total number of the first air outlet 10 and the second air outlet 20 is not less than two.

[0052] Reference Figure 8 In this embodiment, the stator 32 and the rotor 31 of the driving part 30 both adopt an annular structure. The interior of the driving part 30 is hollow, so that the structure of the driving part 30 is relatively light, the fan is lighter, and the air outlet efficiency of the fan is improved; the rotor 31 is arranged outside the stator 32, and the first base 11 is provided with a mounting cavity 112 for accommodating the driving part 30. The rotor 31 is connected to the first base 11 and drives the first base 11 to rotate; the second air outlet 20 is in a driven state. During the rotation of the first base 11, the airflow generated by the rotation of the first fan blades 12 drives the second air outlet 20 to rotate, so that the first air outlet 10 and the second air outlet 20 form relative rotation.

[0053] The connection between the first air outlet 10 and the second air outlet 20 and the driving part 30 is not limited to this. The driving part 30 can be in the form of an inner rotor 31 and an outer stator 32, and the rotor 31 is connected to the second base 21 and drives the second air outlet 20 to rotate; or a combination of an inner rotor 31 and an outer stator 32 and an outer rotor 31 and an inner stator 32 is adopted, and two driving parts 30 are set. The two driving parts 30 are respectively connected to the first air outlet 10 and the second air outlet 20, and drive the first air outlet 10 and the second air outlet 20 to rotate relative to each other, thereby further increasing the wind speed and air volume of the fan.

[0054] In this embodiment, the first base 11 and the second base 21 are both annular, the second base 21 is arranged outside the first base 11, the first blades 12 are distributed on the outer wall of the first base 11, the second blades 22 are distributed on the inner wall of the second base 21, the second blades 22 are inserted between adjacent first blades 12, and the first blades 12 are inserted between adjacent second blades 22. Air enters from the right side of the fan, is continuously pushed and accelerated by the first blades 12 and the second blades 22, and is discharged from the left side of the fan.

[0055] Specifically, Figure 7 As shown, the first blade 12 and the second blade 22 are arranged at intervals, the windward surfaces of the first blades 12 in different rows are in the same direction, and the windward surfaces of the first blade 12 and the adjacent second blade 22 are in opposite directions. In this embodiment, the first blade 12 is tilted downward, and the lower surface of the first blade 12 is its windward surface, and the second blade 22 is tilted upward, and the upper surface of the second blade 22 is its windward surface; assuming that the left side is the wind inlet side and the right side is the wind outlet side, the first blade 12 rotates counterclockwise following the first base 11, and the second blade 22 follows the second base 21 in a driven state; after the wind enters the fan from the left side, the lower surface of the first blade 12 in the first row pushes the air to the right to form an airflow, and the airflow pushes the lower surface of the second blade 22 in the second row, so that the second blade 22 rotates in a clockwise direction, and the lower surface of the first blade 12 in the third row continues to push the air to the right. Preferably, the second blade 22 can also actively rotate clockwise to further enhance the fan's pushing strength on the air and increase the wind speed.

[0056] The first base 11 includes no less than two first units 111, and two adjacent first units 111 can be detachably connected after docking. A plurality of first units 111 are sequentially spliced ​​along the arrangement direction of the first blades 12 and the second blades 22 to form the first base 11, and the outer surface of each first unit 111 is connected to the first blade 12. By segmenting the first base 11, the installation difficulty of the first air outlet 10 and the second air outlet 20, as well as the processing cost of the fan, are reduced, and adjacent first units 111 can be connected by threaded fasteners.

[0057] If the first substrate 11 includes at least three first units 111, the first units 111 can be connected by threaded fasteners, or the first units 111 can be reasonably grouped, each group includes at least two first units 111, and the first units 111 in each group are connected by threaded fasteners.

[0058] The fan further includes a housing 40, and the first air outlet 10, the second air outlet 20 and the driving unit 30 are all placed in the housing 40. A base 50 is also provided below the housing 40 to ensure the overall balance of the fan, and a column 60 is connected between the base 50 and the housing 40, and the column 60 is set as a retractable structure to adjust the air outlet position of the fan and improve the practicality of the fan.

[0059] The housing 40 includes an inner ring 41 and an outer ring 42, both of which are in annular shape, and a receiving cavity 43 is provided between the inner ring 41 and the outer ring 42. A driving unit 30 is provided in the mounting cavity 112 inside the first base 11, and a rotor 31 of the driving unit 30 is connected to the first base 11 and drives the first base 11 to rotate; the second base 21 is rotatably connected to the inner wall of the outer ring 42, so that when the first base 11 rotates, the second blade 22 rotates with the first blade 12, so that the first blade 12 and the second blade 22 form relative rotation. Preferably, there is a gap between the outer side of the first base 11 and the inner wall of the outer ring 42 for airflow to pass through, thereby increasing the amount of air discharged by the fan, and the second base 21 and the outer ring 42 can be connected through a guide rail slider or a bearing.

[0060] Specifically, a plurality of first mounting blocks 113 are arranged along the inner wall of the first base 11, and a plurality of first mounting holes 312 are arranged on the end surface of the rotor 31 along the circumference of the rotor 31. The positions of the first mounting blocks 113 and the first mounting holes 312 can achieve relative fixation of the first base 11 and the rotor 31 by inserting threaded fasteners into the first mounting blocks 113 and the first mounting holes 312, that is, relative fixation of the driving part 30 and the first rotating part. The stator 32 includes a mounting base 322 and a winding group 321 integrally connected to the mounting base 322. A plurality of second mounting blocks 212 are arranged on the outer wall of the inner ring 41 along the circumference of the inner ring 41, and a plurality of second mounting holes 323 are arranged on the end surface of the mounting base 322 along the circumference of the stator 32. By inserting threaded fasteners into the second mounting blocks 212 and the second mounting holes 323, the fixed connection between the mounting base 322 and the inner ring 41 can be achieved, that is, relative fixation of the driving part 30 and the housing 40.

[0061] The housing 40 further includes a first end cap 44 ( Figure 4The first end cover 44 and the second end cover 45 are hidden in the housing 40. The first end cover 44 and the second end cover 45 are respectively arranged on both sides of the inner ring 41 and the outer ring 42. The first end cover 44 and the second end cover 45 are annular and cover between the outer ring 42 and the inner ring 41. The first blade 12 and the second blade 22 are completely contained in the housing 40 to prevent the first blade 12 or the second blade 22 from being touched due to misoperation and causing damage to the human body. The first end cover 44 is provided with an air inlet 441, and the second end cover 45 is provided with an air outlet 451. The air enters from the air inlet 441 and is discharged from the air outlet 451. The air outlet 451 in this embodiment is arranged in a ring shape on the second end cover 45, so that the airflow can be concentrated in the ring to discharge air, thereby optimizing the air outlet effect of the fan.

It can be seen that the inner diameter of the installation cavity 112 in this embodiment is smaller than the inner diameter of the installation cavity 112 in the first embodiment, so the structure of the fan is more compact and light. By adjusting the inner diameter of the installation cavity 112 and selecting different driving parts 30, the fan can meet different usage requirements and improve the application range of the fan.
