[0031] The first fan mechanism 24 includes a linkage assembly 20, a main rotating end 32, a top cover 12, a housing 16, and multiple connecting plates 29. The top cover 12 is hinged to the end of the housing 16. The housing 16 is staggered with multiple strip grooves 34 and slideways 30. The connecting plates 29 slide in the slideways 30. The main rotating end 32 is positioned at the output of the main motor 28. One end of the connecting plate 29 is connected to the main rotating end 32.

[0032] The first fan mechanism 24 further includes four first blades 17 and a first bevel gear 13. The four first bevel gears 13 are pivotally connected to the housing 16 at equal angles with the top cover 12 as the center, and the first blades 17 are arranged on the first bevel gears 13.

[0033] The split fan mechanism 25 includes a plug plate 15, a slider seat 35, a second bevel gear 31, and second blades 18. The plug plate 15 slides within the strip groove 34, and the slider seat 35 is connected to the plug plate 15. The plug plate 15 is movably connected to the top cover 12. The second bevel gear 31 is pivotally connected to the slider seat 35, and the second blades 18 are mounted on the second bevel gear 31.

[0034] The linkage assembly 20 includes an auxiliary rotating end 41, an auxiliary motor 42, a sleeve 39, an electric telescopic rod 22, and a central telescopic rod 43. The auxiliary motor 42 is mounted on the main rotating end 32, and the auxiliary rotating end 41 is mounted on the output end of the auxiliary motor 42. The central telescopic rod 43 is positioned at the center of the auxiliary rotating end 41, and the electric telescopic rod 22 is sleeved onto the central telescopic rod 43. The electric telescopic rod 22 is mounted on the auxiliary rotating end 41, and the movable end of the electric telescopic rod 22 is connected to the sleeve 39.

[0035] The electric telescopic rod 22 also includes a first linkage gear 33 and a second linkage gear 40. The first linkage gear 33 is disposed at the end of the central telescopic rod 43, and the second linkage gear 40 is disposed on the sleeve 39. The first linkage gear 33 meshes with the first bevel gear 13, and the second linkage gear 40 meshes with the second bevel gear 31.

[0036] The lid assembly 5 includes a lid 4, a top plate 23, multiple connecting rods 21, multiple flaps 3, multiple support plates 7, and a slot 6. The lid 4 is hinged to the front opening of the housing 1 and is provided with multiple strip-shaped slots. The flaps 3 are pivotally connected at equal intervals within the strip-shaped slots. The support plates 7 are hinged to the ends of the flaps 3 located within the housing 1. One end of the connecting rod 21 is hinged to the support plates 7, and the other end is hinged to the top plate 23, which corresponds to the insert plate 15.

[0037] The internal curtain-blocking mechanism 26 includes a rubber cover 14, a mounting base 37, multiple rubber rods 36, and a drive hinge base 38. The mounting base 37 is mounted on the main motor 28, and multiple drive hinge bases 38 are arranged on the mounting base 37 at equal angles around the main rotating end 32. The rubber rods 36 are mounted on the output end of the drive hinge base 38, and the rubber cover 14 is sleeved onto the multiple rubber rods 36.

[0038] Working Principle: When the axial flow fan is needed, the hinged seat 38 is driven to retract the rubber rod 36, allowing the rubber cover 14 to rest against the main motor 28. The auxiliary motor 42 is then controlled to rotate the sleeve 39 and the central telescopic rod 43. The first and second linkage gears 33 and 40 then rotate the first and second bevel gears 13 and 31, adjusting the angle of the first blade 17. The main motor 28 is then controlled to rotate the main rotating end 32, allowing the present invention to operate as an axial flow fan.

[0039] When it is necessary to change the direction of air inlet and outlet or use a centrifugal fan, the driving wheel 19 drives the inner sliding sleeve 8 to move along the inner side of the outer shell 1, thereby making way for the opening of the branch channel 2 located on the inner wall of the outer shell 1. Then the auxiliary driving slider 27 moves laterally along the slide bar 9, thereby staggering the first fan mechanism 24 originally arranged coaxially with the outer shell 1. Then the driving hinge seat 38 is controlled to drive the rubber rod 36 to flip, thereby unfolding the rubber cover 14 and blocking the inner sliding sleeve 8. Then the main driving slider 11 is controlled to move along the main slide 10, while the central telescopic rod 43 contracts, and then the electric telescopic rod 22 is driven to extend, forcing the second linkage gear 40 to push the second bevel gear 31 to move along the strip groove 34, while controlling the angles of the first blade 17 and the second blade 18, thereby forming a wind wheel structure, such as Figure 3As shown. Then, during the movement of the slider seat 35, the insert plate 15 is pushed to squeeze the top plate 23, and the top plate 23 forces the connecting rod 21 to push the support plate 7 to move radially. Then, the multiple flaps 3 are pushed by the support plate 7 to overlap with each other and seal the strip grooves on the cover 4. At this time, a closed space is formed between the cover 4 and the unfolded rubber cover 14. Then the main motor 28 is controlled to drive the multiple first blades 17 and second blades 18 to rotate. Then the present invention can meet the working requirements of the centrifugal fan. In this way, by utilizing the deformation process of the fan, the airtight setting of the bellows is completed at the same time, the setting of the additional drive source is reduced, and the structure of the present invention is made more compact.

[0040] In summary, this energy storage closed axial flow fan, through the coordinated arrangement of the first fan mechanism 24, the internal curtain mechanism 26, the main motor 28, the two sub-channels 2, and the multiple split fan mechanisms 25, provides both axial and centrifugal fan configurations, tailored to different user needs. This also reduces component installation space and facilitates the addition of modules with additional functions, significantly facilitating user convenience.
