[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] See also Figure 1-4 A fan-blade structure air outlet for an aircraft air conditioner includes a spherical air guide 100, a mounting seat 200 is rotatably connected to the bottom of the spherical air guide 100, and a first thread 110 is provided on the inner wall of the spherical air guide 100. The invention is characterized in that:

[0028] The air volume adjustment structure is arranged on the inner wall of the first cylinder 300, and the structure is used to change the air volume. When the air outlet angle needs to be adjusted, because the spherical air guide 100 is rotatably connected to the mounting seat 200, the spherical air guide 100 is rotated, and the spherical air guide 100 rotates around its own sphere center. The air volume adjustment structure includes the first cylinder 300, the slot 310, the air guide ring 400, the fan blade 410 and the second thread 420. The inner wall of the spherical air guide 100 is sleeved with the first cylinder 300, and the outer side of the first cylinder 300 is provided with three groups of slots 310. The inner walls of the three groups of slots 310 are clamped with the fan blade 410, and the outer side of the fan blade 410 is fixedly connected with the second thread 420, and the second thread 420 is threadedly connected to the first thread 110, and the top of the fan blade 410 is fixedly connected to the air guide ring 400. On the one hand, when the air volume needs to be adjusted, the spherical air guide member 100 is rotated to rotate the first cylinder 300. In the process of rotating the first cylinder 300, because the fan blade 410 is inserted into the slot 310, the rotation of the first cylinder 300 drives the air guide ring 400 to rotate, and the second thread 420 will also move along the concentric axis of the first thread 110. The top of one end of the first cylinder 300 is movably connected to the bottom of the limit member 500 to control the size of the gap between the air guide ring 400 and the limit member 500, thereby adjusting the air volume circulating in the first cylinder 300.

[0029] Furthermore, the top of the inner wall of the spherical air guide 100 is clamped with the limiting member 500, and the limiting member 500 is hollow. An air inlet 130 is provided at a corresponding position between the inner wall of the limiting member 500 and the outer side of the air guide ring 400. The bottom of the limiting member 500 is movably connected to the top of the first cylinder 300. During actual installation, one end of the second cylinder 320 at the bottom of the first cylinder 300 is first inserted from one end of the air inlet 130 of the spherical air guide 100, and then the limiting member 500 is inserted into the spherical air guide 100.

[0030] Furthermore, an air outlet 140 is provided at the bottom of the spherical air guide 100, and one end of the air outlet 140 is fixedly connected to a corresponding position of the inner wall of the spherical air guide 100 with a buckle 120, and the buckle 120 is annular. The bottom of the limiting member 500 is movably connected to the top of the first cylinder 300, so that one end of the second cylinder 320 passes through one end of the air outlet 140 of the spherical air guide 100, and the outer side of one end of the second cylinder 320 is against the top of the buckle 120.

[0031] Furthermore, the bottom of the first cylinder 300 is fixedly connected to the second cylinder 320, the diameter of the first cylinder 300 is larger than the diameter of the second cylinder 320, the outer side of the second cylinder 320 is clamped together with the top of the buckle 120, and the other end of the second cylinder 320 passes through one end of the air outlet 140. The outer side of the second cylinder 320 is fixedly connected with an anti-slip pad, and the buckle 120 is used to fix the first cylinder 320 to prevent the first cylinder 320 from falling.

[0032] Furthermore, a locking ring 210 is sleeved on the outer side of the mounting base 200, and the locking ring 210 is circular. The mounting base 200 can be installed on the PSU panel on the aircraft. In order to make the installation of the mounting base 200 more stable, a locking ring 210 is provided on the mounting base 200. The locking ring 210 is sleeved on the outer side of the mounting base 200 to ensure that the locking ring 210 fits tightly with the mounting base 200. The locking ring 210 can be gently tightened using appropriate tools to ensure that it is firmly fixed on the mounting base 200.

[0033] Working principle:

[0034] During the actual installation, first insert one end of the second cylinder 320 at the bottom of the first cylinder 300 from one end of the air inlet 130 of the spherical air guide 100, so that one end of the second cylinder 320 passes through one end of the air outlet 140 of the spherical air guide 100, and the outer side of one end of the second cylinder 320 abuts against the top of the buckle 120; then insert the limiter 500 into the spherical air guide 100, wherein the 410 thread will provide a damping force, making the rotating cylinder 300 smaller than It is relatively stable and not easy to loosen. When rotating the rotating drum 300, it will not feel too loose or too tight. The mounting base 200 can be installed on the PSU panel on the aircraft. In order to make the installation of the mounting base 200 more stable, the mounting base 200 is provided with a locking ring 210. The locking ring 210 is put on the outer side of the mounting base 200 to ensure that the locking ring 210 and the mounting base 200 are tightly fitted. The locking ring 210 can be gently tightened with an appropriate tool to ensure that it is firmly fixed on the mounting base 200.

[0035] On the one hand, when it is necessary to adjust the air volume, the spherical air guide member 100 is rotated to rotate the first cylinder 300. During the rotation of the first cylinder 300, because the fan blades 410 are inserted into the slots 310, the rotation of the first cylinder 300 drives the air guide ring 400 to rotate, and the second thread 420 also moves along the concentric axis of the first thread 110. The top of one end of the first cylinder 300 is movably connected to the bottom of the limit member 500 to control the size of the gap between the air guide ring 400 and the limit member 500, thereby adjusting the air volume circulating in the first cylinder 300; on the other hand, when it is necessary to adjust the air outlet angle, the spherical air guide member 100 can be rotated, and the spherical air guide member 100 rotates around its own spherical center; in this way, by rotating the spherical air guide member 100, the air outlet direction of the air conditioner can be changed; by rotating the first cylinder 300, the air guide ring 400 is moved to change the air outlet; the structure is simple and the manufacturing cost is low; the operation method is simple and easy to understand, and it is basically suitable for users of all ages.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
