Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0026] Combine Figure 1 The utility model provides an adjustable central air-conditioning air outlet mechanism, including an air outlet fixed frame mechanism 1, a direction adjustment drive mechanism 2 is fixedly arranged inside the air outlet fixed frame mechanism 1, and a fan blade mechanism 3 is rotatably arranged at the output end of the direction adjustment drive mechanism 2. The air outlet fixed frame mechanism 1 includes two groups of side frame plates 13, a bottom frame 11 connected to the lower ends of the two groups of side frame plates 13, the direction adjustment drive mechanism 2 includes a bidirectional servo motor 21 fixed inside the bottom plate 12, two groups of transmission members 22 connected to the output ends on both sides of the bidirectional servo motor 21, a connecting rod 23 is rotatably sleeved on one side of the transmission member 22, and a first transmission rod 231 and a second transmission rod 232 are rotatably sleeved on the two groups of connecting rods 23 respectively. The fan blade mechanism 3 includes a rotating rod locking member 31 connected to one side of the first transmission rod 231 or the second transmission rod 232, and a rotating fan blade assembly 32 sleeved on the rotating rod locking member 31.

[0027] Specifically, the bottom frame 11 and the two groups of side frame plates 13 are fixed to each other, and the two-way servo motor 21 is set in two halves. The two-way servo motor 21 drives the transmission members 22 on both sides to rotate in opposite directions, thereby driving the two groups of connecting rods 23 connected to one side of the transmission member 22 to shift synchronously and rise or fall at the same time. The two groups of connecting rods 23 are respectively connected to the multiple groups of first transmission rods 231 and second transmission rods 232 on both sides. One side of the first transmission rod 231 is connected to the rotating fan blade assembly 32, and one side of the second transmission rod 232 is connected to the rotating fan blade assembly 32, and the rotating fan blade assembly 32 connected by the first transmission rod 231 and the rotating fan blade assembly 32 connected by the second transmission rod 232 are cross-arranged adjacently. The rotation of the two-way servo motor 21 drives the cross-adjacent rotating fan blade assemblies 32 to rotate in opposite directions to achieve air outlet adjustment. In this structure, the detachable setting of the air outlet fixing frame mechanism 1 and the direction adjustment drive mechanism 2 makes it easy to disassemble the air outlet and convenient to clean. The direction adjustment drive mechanism 2 is set to adjust the rotation of the fan blade mechanism 3 to prevent the air outlet direction from being too concentrated and balance the air volume in multiple directions.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combine Figure 2-Figure 4 The air outlet fixing frame mechanism 1 also includes a bottom plate 12 connected to the lower end of the bottom frame 11 by screws, and a top plate 14 fixedly arranged on the upper ends of the two sets of side frame plates 13. The bottom plate 12 fixes and seals the lower end of the bottom frame 11. The side frame plates 13, the top plate 14 and the bottom frame 11 form an integral rectangular frame and are easy to disassemble.

[0031] A positioning opening 132 is provided on the outer side of the side frame plate 13 , and a slot 131 is provided at the lower end of the positioning opening 132 . The connecting rod 23 is movably engaged in the slot 131 , and the fan mechanism 3 and the first transmission rod 231 are movably engaged in the positioning opening 132 .

[0032] The two output ends of the bidirectional servo motor 21 are provided with rotating rods 211. The bidirectional servo motor 21 drives the two groups of rotating rods 211 on both sides to rotate in opposite directions. The rotating rods 211 are fixedly connected to the transmission member 22. The rotating rods 211 drive the transmission member 22 to rotate, thereby driving the connecting rod 23 to shift in the slot 131.

[0033] Five groups of first transmission rods 231 are arranged in parallel, and five groups of second transmission rods 232 are arranged in parallel. The two groups of counter-rotating rotating rods 211 respectively drive the five groups of first transmission rods 231 and the five groups of second transmission rods 232 to rise and fall synchronously, thereby driving the rotating fan blade assembly 32 to adjust the angle.

[0034] Example 2:

[0035] Combine Figure 5 and Figure 6The rotating fan blade assembly 32 includes a fan blade sleeve rod 321 inserted between the two sets of side frame plates 13, and the rotating rod locking piece 31 is sleeved on both sides of the fan blade sleeve rod 321. The rotating rod locking pieces 31 on both sides are used to fix the fan blade sleeve rod 321.

[0036] The rotating blade assembly 32 further includes a rotating blade 322 fixedly connected to the blade sleeve rod 321 . The rotating blade 322 is driven by the connecting rod 23 to rotate and adjust.

[0037] One end of the rotating blade 322 is set as a triangular piece 3221, and the other end is set as a single leaf piece 3222. The triangular piece 3221 and the single leaf piece 3222 are staggered and close to each other, so that the air outlet position and air volume of the air outlet can be adjusted. At the same time, the two adjacent groups of triangular pieces 3221 can contact and seal with each other under the drive of the connecting rod 23, so that the spatial distribution of the air outlet is large inside and small outside, thereby realizing wind speed adjustment. The air-conditioned air under this structure is further cooled, achieving energy-saving effect.
