[0014] The beneficial effects of the present invention are: a simple structure, an effective conversion of direct air supply into natural-like air, an effective change to expand the heat dissipation area, and an aircraft cabin cooling system and method without the need for additional power. The specific implementation method is as follows: The operator first uses the air source to pass the appropriate temperature cold air from the air supply pipe into the buffer tank for standby use. When no one in the cabin needs cooling, the buffer tank is started to deliver cold air from the branch pipe on the air intake pipe. At the same time, the ventilation pipe is used in conjunction with the two-way air pump to output cold air from the ventilation box on the connecting pipe for rapid cooling. After the temperature reaches the appropriate level, the two-way air pump changes the air supply direction, and the ventilation box starts to draw air into the buffer tank. The ventilation box can be installed under the seat below the branch pipe to speed up the branch pipe's air supply efficiency. When the air is transmitted through the branch pipe, it is output from the exhaust through-hole on the branch pipe to the ventilation groove on the twisting disk. During air transmission, due to the angle between the twisting disks, the ventilation amounts of the branch pipe through the ventilation grooves are different when the cold air is evenly transmitted, resulting in the ventilation groove on the twisting disk with small ventilation amount gradually becoming larger. At the same time, the abutting toggle lever installed on it to toggle the rotating toggle lever of the connected toggle disk to torsion the torsion spring. The torsion spring is subjected to the resistance and drives the torsion disk installed on it to rotate, resulting in the gap between its ventilation groove and the exhaust through-hole becoming smaller, so that it is replaced by the torsion disk with small ventilation amount. The above process is repeated during the recovery process. At the same time, due to the continuous twisting of the outer torsion disk in the hall, the air pressure near the exhaust through-hole near the torsion disk of the small rehearsal is higher than that in other areas. In actual use, a reciprocating change effect is produced, which realizes the continuous twisting and rotation of the torsion disk, resulting in an irregular suppression effect on the exhaust through-hole on the branch pipe, thereby reducing the exhaust wind speed of the branch pipe and producing a discharge effect similar to natural wind, which is effectively adapted to different groups of people. In actual use, the ventilation volume usually needs to be changed in time due to the different feelings of each person. At this time, by rotating the rotary control shaft and changing the covering position of the semicircular long plate on the exhaust hole, the ventilation volume of the exhaust hole can be changed. At the same time, since the rotating semicircular plate is set to separate the middle part of the semicircular long plate, half of the exhaust holes close to the air source and the other exhaust holes are supplied with air separately and evenly, which improves the air supply efficiency and reduces the air supply loss. The rotary control shaft can also be installed in the form of a gear set or the like near the corresponding operating area for easy adjustment. This is an existing technology, so it will not be repeated here.

[0015] When exhausting air, in order to adapt to different discharge areas and facilitate cooling in different areas, the tilted prying frame is in a horizontal position. When in use, the tilted prying frame is rotated along the rotating support rod. During the tilting process of the prying frame, the positioning rod on the guide rod on the side where the prying frame moves upward resists the thrust of the thrust spring in the rectangular groove of the guide vertical plate, driving the connecting lifting block to move downward by the guiding action of the sliding groove, pressing down part of the guide rod, and rotating the gear hand rack due to the meshing action, so that the upper part of the air guide plate is tilted toward the rotating support rod. The closer the fixed frame is to the rotating support rod, the smaller the tilt angle is, and the air guide plate on the other side is symmetrically arranged due to the installed adjustment assembly. It gradually moves away from the positioning rod, causing the guide rod to pull the rotating auxiliary rod to resist the thrust spring to move upward, resulting in the air guide plate on the other side rotating in the same direction as the above angle, but the tilt angle is much greater than the air guide plate at one end of the upward prying frame. During the air supply process of the ventilation slot, the air supply changes from direct air to umbrella-shaped expansion, effectively increasing the air supply area. It is only necessary to adjust the tilt upward, close to the torsion disk and the rotation angle according to actual use.

[0016] The device has a simple structure and effectively utilizes the changes in the air supply and passage ducts to achieve the change from direct air supply to natural wind. At the same time, it can effectively adjust the air supply area, has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the implementation, when the gas is delivered, because the twist plates 25 are left with an included angle, the air flow through the air slots 2511 of the shunt pipes 22 is different, which causes the air slots 2511 of the twist plate 25 with small air flow to gradually increase, and the abutting rotating rod 226 installed thereon drives the rotating rod 223 of the connected twist plate 25 to twist the torsion spring 222. The torsion spring 222 is driven to rotate by the resistance, which causes the gap between the air slots 2511 and the exhaust hole 221 to become smaller, so that it replaces the twist plate 25 with small air flow. In the recovery process, the above process is repeated, and at the same time, the twist plates 25 in the surrounding area are twisted and changed, which causes the air pressure near the exhaust hole 221 near the twist plate 25 with small air flow to be higher than that in other areas. In actual use, the effect of reciprocating change is generated.

[0027] Beneficially, the air regulating member includes a connecting guide frame 251, which is close to the outlet side of several twisting disks 25. The connecting guide frame 251 is provided with a fixed frame 24 on the side away from the twisting disk 25. The fixed frame 24 has a rectangular frame structure, and a prying frame 243 is provided inside the fixed frame 24. The prying frame 243 has a rectangular frame structure. A corrugated connecting frame 252 is provided between the connecting guide frame 251 and the prying frame 243, which can be freely extended and extended, similar to a bellows, etc., mainly used to match the circular arc in the cabin, etc. A rotating support rod 241 is provided in the middle of both ends of the prying frame 243, and the rotating support rod 241 passes through and is rotatably connected to the fixed frame 24. Several air guide plates 26 are provided in the middle of the prying frame 243, and the axis of the air guide plate 26 is parallel to the axis of the rotating support rod 241. Adjustment components are provided at both ends of the air guide plate 26 to cooperate with the prying frame 243 to rotate and tilt the air guide plate 26 on the rotating support rod 241.

[0028] Advantageously, the number of the plurality of air guide plates 26 is an even number, and the adjustment components at both ends of the midline of the plurality of air guide plates 26 are symmetrically arranged. Advantageously, the adjustment component includes a rotation auxiliary rod 261, and the end of the rotation auxiliary rod 261 away from the air guide plate 26 is provided with a guide vertical plate 262, and the middle of the guide vertical plate 262 is provided with a rectangular groove 2621, and the rotation auxiliary rod 261 passes into the rectangular groove 2621.

A rotation gear 2611 is also provided in the middle of the rotation auxiliary rod 261, and the rotation gear 2611 is close to the rotation auxiliary rod 261. A rack 2612 is provided on one side of the edge of the prying frame 243, and the rotating gear 2611 engages with the rack 2612.

A guide rod 271 is provided on the connecting lifting block 27, and a sliding groove 273 is provided at the end of the guide rod 271 away from the connecting lifting block 27.

The positioning rod 272 is slidably connected to the sliding groove 273, and the positioning rod 272 is fixedly connected to the nearby torsion disk 25.

[0029] In practice, the prying frame 243 is rotated and tilted along the rotating support rod 241. During the tilting process of the prying frame 243, the positioning rod 272 on the guide rod 271 on the side where the prying frame 243 moves upward resists the thrust of the thrust spring 2622 in the rectangular groove 2621 in the guide vertical plate 262, driving the connecting lifting block 27 to move downward under the guidance of the sliding groove 273, pressing down part of the guide rod 271, and rotating the gear 2611 to rotate the meshing action of the rack 2612, so that the air guide plate 26 is rotated upward toward the rotating support rod. 241 direction, the closer the fixed frame 24 is to the rotating support rod 241, the smaller the inclination angle is, and the air guide plate 26 on the other side is symmetrically arranged due to the installed adjustment components, and it gradually moves away from the positioning rod 272, so that the guide rod 271 pulls the rotation auxiliary rod 261 to resist the thrust spring 2622 to move upward, resulting in the air guide plate 26 on the other side rotating in the same direction as the above angle, but the inclination angle is much greater than the air guide plate 26 at one end of the upward prying frame 243. During the gas transmission process of the ventilation slot 2511, the air supply changes from direct air injection to umbrella-shaped expansion.

[0030] In terms of implementation, it also includes a method for cooling an aircraft cabin, and the specific implementation method is as follows: S1. The operator first inputs the gas source 1 into the gas supply pipe 3, which is then stored in the buffer tank 31, waiting for use; S2. The air is passed into the shunt tube 22, and the air flow blows out of the vent groove 2511 in the twisting disk 25 and flows into the air regulating member; S3. Adjust the air conditioning components to direct the required cooling air to the desired area; S4 airflow drives the toggle member to rotate the twist disk 25, so that the cooling air output presents a natural wind state; S5. When cooling is no longer required, the exhaust hole 221 is closed and exhaust is stopped.

[0031] Working principle of the present invention: The operator first uses the air source 1 to pass the appropriate temperature cold air from the air supply pipe 3 into the buffer tank 31 for standby use. When no one in the cabin needs to cool down, the buffer tank 31 is started to deliver cold air from the branch pipe 22 on the air inlet pipe 21. At the same time, the ventilation pipe 32 is used in conjunction with the two-way air pump 33 to output cold air from the ventilation box 35 on the connecting pipe 34 for rapid cooling. After the temperature reaches the appropriate temperature, the two-way air pump 33 changes the air delivery direction, and the ventilation box 35 begins to absorb air and input it into the buffer tank 31. The ventilation box 35 can be installed under the seat below the branch pipe 22 to speed up the air delivery efficiency of the branch pipe 22. When the branch pipe 22 is transmitting air, the air is output from the exhaust through hole 221 on the branch pipe 22 to the vent groove 2511 on the twisting disk 25. When transmitting air, due to the angle between the twisting disks 25, the ventilation amount of the branch pipe 22 through the vent groove 2511 is different when the cold air is uniformly transmitted, resulting in the vent groove 2511 on the twisting disk 25 with a small ventilation amount gradually becoming larger. At the same time, the abutting toggle rod 226 installed thereon toggles the rotating toggle rod 223 of the connected toggle disk 25 to twist the torsion spring 222. The torsion spring 222 is resisted and drives the torsion disk 25 on which it is installed to rotate, causing the vent groove 2511 to rotate. The gap between 511 and the exhaust through-hole 221 becomes smaller, so that it is replaced by the twisting disk 25 with a small ventilation volume. The above process is repeated during the recovery process. At the same time, due to the continuous twisting of the outer twisting disk 25 in the hall, the air pressure near the exhaust through-hole 221 near the twisting disk 25 during the rehearsal is higher than that in other areas. In actual use, a reciprocating change effect is produced, and the continuous twisting and rotation of the twisting disk 25 is achieved, which produces an irregular suppression effect on the exhaust through-hole 221 on the branch pipe 22, thereby reducing the exhaust wind speed of the branch pipe 22 and producing a discharge effect similar to natural wind, effectively adapting to different groups of people; During actual use, the ventilation volume usually needs to be changed in time due to the different feelings of each person. At this time, by rotating the rotating control shaft 284 and changing the covering position of the semicircular long plate 281 on the exhaust hole 221, the ventilation volume of the exhaust hole 221 can be changed. At the same time, since the rotating semicircular plate 28 is set to separate the middle part of the semicircular long plate 281, half of the exhaust holes 221 close to the air source 1 and the other exhaust holes 221 are supplied with air separately and evenly, thereby improving the air supply efficiency and reducing the air supply loss. The rotating control shaft 284 can also be installed in the form of a gear set or the like near the corresponding operating area for easy adjustment. This is a prior art and will not be described in detail.

[0032] When exhausting air, in order to adapt to different exhaust areas and facilitate cooling in different areas, the tilting prying frame 243 is in a horizontal position. When in use, the tilting prying frame 243 is rotated along the rotating support rod 241. During the tilting process of the prying frame 243, the positioning rod 272 on the guide rod 271 on the side where the prying frame 243 moves upward resists the thrust of the thrust spring 2622 in the rectangular groove 2621 in the guide vertical plate 262, driving the connecting lifting block 27 to move downward under the guidance of the sliding groove 273, pressing down part of the guide rod 271, and rotating the gear 2611 and the hand-operated rack 2612 to rotate, so that the air guide plate 26 is rotated upward toward the rotating support rod 241. The direction is tilted, and the closer the fixed frame 24 is to the rotating support rod 241, the smaller the tilt angle is. The air guide plate 26 on the other side is symmetrically arranged due to the installed adjustment components. It gradually moves away from the positioning rod 272, so that the guide rod 271 pulls the rotation auxiliary rod 261 to resist the thrust spring 2622 to move upward, resulting in the air guide plate 26 on the other side rotating in the same direction as the above angle, but the tilt angle is much greater than the air guide plate 26 at one end of the upward prying frame 243. During the air supply process of the ventilation groove 2511, the air supply is changed from direct air to umbrella-shaped expansion, which effectively increases the air supply area. It is only necessary to refer to the actual use to adjust the tilt of the prying frame 243 side upward close to the torsion disk 25 and the rotation angle.
