The air outlet housing 101 has a hollow structure that penetrates from front to back. The blade and drive system 106 is disposed inside the air outlet housing 101. The air outlet front baffle 102, the air outlet front cover 103, and the air outlet front end cover 104 are sequentially arranged on the front side of the air outlet housing 101. The air outlet rear end cover 105 is arranged on the rear side of the air outlet housing 101. The air outlet front cover 103 is used to protect the drive device of the blades. The first air outlet 131 is provided on the air outlet front end cover 104, and the second air outlet 132 is provided on the air outlet rear end cover 105. The blade and drive system 106 includes a first blade system 112, a second blade system 114, and a drive device. The drive device includes a first transmission device and a second transmission device 124, which are respectively used to drive the first blade system 112 and the second blade system 114. The drive device also has an adjustment piece 126 that protrudes substantially towards the air outlet front cover 103. By controlling the sliding and swinging of the adjustment piece 126, the swinging angles of the first blade system 112 and the second blade system 114 can be adjusted. An adjustment piece opening 134 is provided on the air outlet front cover 103. As Figure 1A shown in the assembled state, the adjustment piece 126 can pass through the adjustment piece opening 134 and extend to the outside of the air outlet device 100, so that the operator can touch and control the adjustment piece 126.

[0030] Figures 2A - 2B shows Figure 1C the specific structure of the blade and drive system in Figure 2A which Figure 1C is an exploded view of the blade and drive system in Figure 2B and Figure 2A is a schematic diagram of the cooperation of the sliding shaft and the operating member shown in

[0031] As Figure 2AAs shown, the blade and drive system 106 includes a first blade system 112, a second blade system 114, and a drive device. The first blade system 112 has a first blade rotation axis 202, and the second blade system 114 has a second blade rotation axis 204. The first blade system 112 can swing around the first blade rotation axis 202 to change the airflow direction flowing through the first blade system 112. The second blade system 114 can swing around the second blade rotation axis 204 to change the airflow direction flowing through the second blade system 114. In the embodiment of the present application, the first blade rotation axis 202 and the second blade rotation axis 204 are perpendicular to each other. For example, the first blade rotation axis 202 is arranged in the vertical direction, and the second blade rotation axis 204 is arranged in the horizontal direction. For those skilled in the art with at least ordinary skills, in some other embodiments, the first blade rotation axis 202 and the second blade rotation axis 204 can also be arranged at other angles or parallel to each other.

[0032] Continue as Figure 2A As shown, the drive device includes a drive shaft 206, a control member 208, a first transmission device, and a second transmission device 124. The first transmission device and the second transmission device 124 are respectively used to drive the first blade rotation axis 202 and the second blade rotation axis 204 to rotate, so as to drive the first blade system 112 and the second blade system 114 to swing.

[0033] As Figure 2A and 2BAs shown, the first transmission device is a paddle 210. A sliding portion 222 is provided on the side of the operating component 208 facing the drive shaft 206, and a slide groove 224 and a paddle mounting portion 226 are provided on the sliding portion 222. The drive shaft 206 can pass through the slide groove 224 in the axial direction, so that the operating component 208 can slide back and forth on the drive shaft 206 along the axial direction of the drive shaft 206. The axial middle section of the drive shaft 206 protrudes radially outward to form a plurality of sliding shaft pins 225, and the sliding shaft pins 225 extend in the axial direction of the drive shaft 206. The sliding shaft pins 225 can pass through the slide groove 224 so as to be in shape matching with the slide groove 224. In the embodiment of the present application, the slide groove 224 is set in the form of a cross groove, so as to be matched and connected with the four sliding shaft pins 225 protruding radially outward from the drive shaft 206, so that the drive shaft 206 cannot rotate relative to the slide groove 224 in the slide groove 224. The driving shaft 206 is provided with stoppers 262 near both ends of the axial direction, which are used to limit the sliding range of the operating member 208 on the driving shaft 206. When the operating member 208 rotates relative to the axial direction of the driving shaft 206, the driving shaft 206 can be driven to rotate in the axial direction. The paddle 210 is hinged on the paddle mounting portion 226 of the operating member 208. When the operating member 208 slides back and forth on the driving shaft 206 along the axial direction of the driving shaft 206, the operating member 208 can drive the paddle 210 to reciprocate along the axial direction of the driving shaft 206. The first blade system 112 is provided with a blade actuator 242, which is coaxially arranged with the first blade rotating shaft 202, and the blade actuator 242 is arranged in linkage with the first blade rotating shaft 202. The blade actuator 242 extends outward in the radial direction, and the extending direction is substantially the same as the extending direction of the blades of the first blade system 112. A sliding rod 243 is provided at the outwardly extending end of the blade actuating portion 242 . The extending direction of the sliding rod 243 is parallel to the extending direction of the first blade rotating shaft 202 .

[0034] A groove 232 is provided on one side of the paddle 210 facing the blade. The groove 232 has a certain depth. The width of the opening of the groove 232 is greater than or equal to the width of the slide rod 243 of the blade actuator 242 , so that the protruding portion of the blade actuator 242 can be accommodated in the opening of the groove 232 .

[0035] An adjusting piece 126 is provided on one side of the operating member 208 facing the air outlet front cover 103, and the adjusting piece 126 is formed by protruding from the outer side of the operating member 208. When the operator turns the adjusting piece 126 in the horizontal direction, the adjusting piece 126 drives the paddle 210 to reciprocate along the axial direction of the driving shaft 206, and the groove 232 of the paddle 210 can accommodate the blade actuator 242 therein, so that the left and right movement of the groove 232 can contact the blade actuator 242 and actuate the blade actuator 242 to swing left and right, thereby driving the first blade rotation shaft 202 to rotate.

[0036] Continue as Figure 2A shown, the second transmission device 124 is a linkage mechanism, including an input link 252, a transmission link 254, and an output link 256 that are hinged to each other. The input link 252 is fixedly connected to an axial end of the drive shaft 206, and the output link 256 is fixedly connected to an axial end of the second blade rotating shaft 204. Therefore, the self-rotation of the drive shaft 206 along its axis can be converted into the rotation of the second blade rotating shaft 204 along its axis through the above linkage mechanism, thereby driving the second blade system 114 to swing up and down. When the operator toggles the adjusting piece 126 in the up and down direction, it will drive the adjusting piece 126 to rotate axially around the drive shaft 206, thereby driving the operating member 208 to rotate axially relative to the drive shaft 206, and then converted into the rotation of the drive shaft 206 in the axial direction, and finally converted into the up and down swing of the second blade system 114. When the operator toggles the adjusting piece 126 in the up and down direction, the paddle 210 can be driven to swing up and down. Since the blade actuating portion 242 passes through the groove 232 of the paddle 210 in a direction perpendicular to the groove 232, the up and down swing of the paddle 210 and its groove 232 causes the groove 232 to slide over the slide bar 243 of the blade actuating portion 242, so the blade actuating portion 242 will not be actuated to move.

[0037] For those skilled in the art with at least ordinary skills, the second transmission device can also be set as a gear assembly, that is, the rotation of the drive shaft 206 is transmitted to the rotation of the second blade rotating shaft 204 by means of gear meshing, thereby driving the second blade system 114 to swing up and down.

[0038] In the above way, when the operator toggles the adjusting piece 126 in the horizontal direction, the operating member 208 slides horizontally on the drive shaft 206, and the drive shaft 206 itself does not move. The horizontal sliding of the operating member 208 on the drive shaft 206 will drive the paddle 210 to move back and forth, thereby actuating the blade actuating portion 242 to swing left and right, and then driving the first blade system 112 to swing left and right. Since the drive shaft 206 itself does not move and the second transmission device 124 does not move, the second blade system 114 is not actuated.

[0039] When the operator toggles the adjusting piece 126 in the up and down direction, it will drive the drive shaft 206 to rotate axially through the operating member 208, so that the second transmission device 124 (linkage mechanism or gear assembly) drives the second blade system 114 to swing up and down. Since the blade actuating portion 242 passes through the groove 232 of the paddle 210 in a direction perpendicular to the groove 232, the up and down swing of the operating member 208 and its paddle 210 will not drive the blade actuating portion 242 to move, so the first blade system 112 is not actuated.

[0040] For those skilled in the art with at least ordinary skills, the first transmission device and the second transmission device in the above embodiments can be replaced with each other without affecting the function of the air outlet device.

[0041] Figures 3A - 3C The specific structure of the second embodiment of the air outlet device is shown, where Figure 3A is a perspective view of the second embodiment of the air outlet device of the present application from the first perspective; Figure 3B is a perspective view of the second embodiment of the air outlet device of the present application from the second perspective; Figure 3C is Figure 3A an exploded view of the second embodiment of the air outlet device shown.

[0042] The design concept of the second embodiment of the air outlet device and the first embodiment is that a single operating member (e.g., the adjusting piece 126 or the lever 326) moves in different directions to respectively actuating the first vane system 112 and the second vane system 114 to swing, except for the difference in the setting of the transmission method.

[0043] As Figures 3A - 3C shown, the air outlet device 300 includes an air outlet housing 301, an air outlet front cover 303, an air outlet front end cover 304, an air outlet rear end cover 305, and a vane and drive system 306. The air outlet housing 101 has a hollow structure that penetrates through the front and back. The vane and drive system 306 is disposed inside the air outlet housing 301. The air outlet front cover 303 and the air outlet front end cover 304 are sequentially arranged on the front side of the air outlet housing 301, and the air outlet rear end cover 305 is arranged on the rear side of the air outlet housing 301. The air outlet front end cover 304 is provided with a first air outlet 131, and the air outlet rear end cover 305 is provided with a second air outlet 132. The vane and drive system 306 includes a first vane system 112, a second vane system 114, and a drive device. The drive device includes a first transmission device 322 and a second transmission device 324, which are respectively used to drive the first vane system 112 and the second vane system 114. The drive device also has a lever 326 that protrudes substantially toward the air outlet front cover 303. By controlling the swing of the lever 326 in various directions, the swing angles of the first vane system 112 and the second vane system 114 can be adjusted. A lever opening 334 is provided on the air outlet front end cover 304. As Figure 3A shown in the assembled state, the lever 326 can pass through the lever opening 334 and extend to the outside of the air outlet device 300, so that the operator can touch and manipulate the lever 326.

[0044] Figure 4 is Figure 3C an exploded view of the vane and drive system in

[0045] As Figure 4As shown, the blade and drive system 306 includes a first blade system 112, a second blade system 114, and a drive device. The first blade system 112 has a first blade rotation axis 402, and the second blade system 114 has a second blade rotation axis 404. The first blade system 112 can swing around the first blade rotation axis 402 to change the airflow direction flowing through the first blade system 112; the second blade system 114 can swing around the second blade rotation axis 404 to change the airflow direction flowing through the second blade system 114. In the embodiment of the present application, the first blade rotation axis 402 and the second blade rotation axis 404 are perpendicular to each other. For example, the first blade rotation axis 402 is arranged in the vertical direction, and the second blade rotation axis 404 is arranged in the horizontal direction. For those skilled in the art with at least ordinary skills, in some other embodiments, the first blade rotation axis 402 and the second blade rotation axis 404 can also be arranged at other angles or in parallel.

[0046] Continue as Figure 4 As shown, the drive device includes a control part, a first transmission device 322, and a second transmission device 324. The first transmission device 322 and the second transmission device 324 are respectively used to drive the first blade rotation axis 402 and the second blade rotation axis 404 to rotate, so as to drive the first blade system 112 and the second blade system 114 to swing. The control part includes a universal ball 432, a universal ball receiving part 434, and a lever 426. The universal ball 432 moves in the universal ball receiving part 434, and the lever 426 is fixedly connected to the front side of the universal ball 432 and is used to control the movement of the universal ball 432. The universal ball 432 is provided with at least one limit protrusion 436 in the horizontal direction, and the corresponding position of the universal ball receiving part 434 in the horizontal direction is provided with at least one limit groove 438 for receiving the limit protrusion 436 of the universal ball 432 to move therein. The limit groove 438 is arranged in the horizontal direction, so that the universal ball 432 can swing in the left-right direction and the up-down direction in the universal ball receiving part 434.

[0047] Continue as Figure 4As shown, the first transmission device 322 is composed of a gear assembly. In this embodiment, the gear assembly includes a sector gear 422 connected to the universal ball 432, a first blade gear 427 coaxially and linked with the first blade rotating shaft 402, and a transmission gear 424 meshing and driving the sector gear 422 and the first blade gear 427 respectively. The top of the universal ball 432 is provided with a universal ball connection groove 442 extending along the length direction of the lever 426. Below the rotating shaft 443 of the sector gear 422, there is a narrow universal ball convex connection part 444. The length direction of the universal ball convex connection part 444 is consistent with the extending direction of the universal ball connection groove 442, and the length of the universal ball convex connection part 444 is less than the groove length of the universal ball connection groove 442, so that the universal ball convex connection part 444 can be inserted into the universal ball connection groove 442 and can be accommodated to move along the length direction of the groove in the universal ball connection groove 442. The universal ball accommodating part 434 is provided with a top opening 437 at the top for accommodating the rotating shaft 443 of the sector gear 422. The universal ball convex connection part 444 of the sector gear 422 can pass through the top opening 437 of the universal ball accommodating part 434 and be inserted downward into the universal ball connection groove 442, and the rotating shaft 443 of the sector gear 422 can be accommodated to rotate in the top opening 437. When the universal ball 432 swings left and right, the narrow universal ball connection groove 442 can drive the equally narrow universal ball convex connection part 444 to swing left and right, so that the sector gear 422 swings reciprocally, and then drives the first blade rotating shaft 402 to rotate through the transmission gear 424 and the first blade gear 427, thereby actuating the first blade system 112 to swing left and right.

[0048] Since the length of the universal ball convex connection part 444 is less than the groove length of the universal ball connection groove 442, the universal ball convex connection part 444 has a sliding margin along the length direction in the universal ball connection groove 442. When the universal ball 432 swings up and down, the universal ball connection groove 442 will slide relative to the universal ball convex connection part 444. The narrow universal ball connection groove 442 swinging along the length direction of the groove will not drive the universal ball convex connection part 444 to move, and due to the limitation of the top opening 437 of the universal ball accommodating part 434, the sector gear 422 cannot swing with the up and down swing of the universal ball 432 either.

[0049] Continue as Figure 4 As shown, the second transmission device 324 is also composed of a gear assembly and has two sector gears, namely a first sector gear 452 and a second sector gear 454. The first sector gear 452 is fixedly connected to the rear side of the universal ball 432 and can move with the movement of the universal ball 432. The rotating shaft part of the second sector gear 454 protrudes axially from the gear fixing part, such as a spline 455, so that it can be fixedly connected to the second blade rotating shaft 404, so that the second sector gear 454 is in a linked state with the blade rotating shaft 404.

[0050] When the universal ball 432 swings up and down, the first sector gear 452 swings up and down accordingly. The first sector gear 452 can drive the second sector gear 454 to swing through the tooth engagement with the second sector gear 454, thereby driving the blade rotating shaft 404 to rotate, and finally actuating the second blade system 114 to swing up and down.

[0051] Figures 5A - 5C The top view of the engagement between the first sector gear 452 and the second sector gear 454 is shown, where Figure 5A is Figure 4 the schematic diagram of the engagement of the arc-shaped tooth surface structure shown; Figure 5B is Figure 5A the first sliding schematic diagram of the arc-shaped tooth surface structure shown; Figure 5C is Figure 5A the second sliding schematic diagram of the arc-shaped tooth surface structure shown.

[0052] As Figure 5A shown, the first sector gear 452 has the first sector gear teeth 502. In the extending direction parallel to the gear rotating shaft, the tooth tips of the first sector gear teeth 502 are arc-shaped, so that the first sector gear 452 has an arc-shaped tooth surface structure. The center of the arc of this tooth surface structure approximately coincides with the rotation / swing center of the first sector gear 452 rotating in the direction perpendicular to the gear engagement transmission. The second sector gear 454 has the second sector gear teeth 504, and the second sector gear teeth 504 have a rectangular tooth surface structure in the direction perpendicular to the tooth surface. In the state where the universal ball 432 does not swing left and right, the first sector gear 452 maintains the normal tooth surface engagement with the second sector gear 454, and can perform engagement transmission during the up and down swing of the universal ball 432. Due to the arc-shaped tooth surface structure, the tooth engagement area between the first sector gear 452 and the second sector gear 454 gradually decreases from the center of the tooth surface to the edge of the tooth surface.

[0053] As Figures 5B - 5C shown, when the universal ball 432 swings left and right, the first sector gear 452 also swings accordingly. The arc-shaped first sector gear teeth 502 can slide between the teeth of the second sector gear teeth 504. During the sliding process, the arc-shaped tooth surface structure prevents the first sector gear teeth 502 from colliding and interfering with the second sector gear teeth 504. Therefore, the left and right swing of the first sector gear 452 does not drive the second sector gear 454 to move.

[0054] In the above manner, when the operator toggles the lever 426 in the horizontal (left - right) direction, the universal ball 432 swings left and right. Through the sector gear 422, the driving transmission gear 424, and the first vane gear 427, the first vane system 112 is driven to swing left and right. Since the first sector gear 452 only slides relative to the second sector gear 454 during left - right swinging and does not mesh with the second sector gear 454 for transmission, the second vane system 114 is not actuated.

[0055] When the operator toggles the lever 426 up and down, the universal ball 432 swings up and down. Through the meshing transmission between the first sector gear 452 and the second sector gear 454, the second vane system 114 is driven to swing up and down. Since the narrow and long universal ball connecting groove 442 slides relative to the universal ball convex connecting portion 444 during the up - down swinging of the universal ball 432 and does not drive the sector gear 422 to move, the first vane system 112 is not actuated.

[0056] For those skilled in the art with at least ordinary technical knowledge, the second sector gear teeth 504 can also be set to an arc - shaped tooth surface structure, the first sector gear teeth 502 can be set to a rectangular tooth surface structure, or both the first sector gear teeth 502 and the second sector gear teeth 504 can be set to arc - shaped tooth surface structures.

[0057] For those skilled in the art with at least ordinary technical knowledge, the second transmission device 324 can also be set as a fork assembly. Through reasonable setting, the fork assembly only transmits the up - down swinging of the universal ball 432 to the rotation of the second vane rotating shaft 404, thereby driving the second vane system 114 to swing up and down; the left - right swinging of the universal ball 432 is not transmitted to the second vane rotating shaft 404 through the fork assembly, thus achieving the movement isolation between the left - right swinging of the universal ball 432 and the movement of the second vane system 114.

[0058] For those skilled in the art with at least ordinary technical knowledge, the first transmission device 322 and the second transmission device 324 in the above - mentioned embodiments can be mutually replaced without affecting the function of the air - outlet device.

[0059] The air - outlet device of the present application can at least achieve the following beneficial technical effects:

[0060] First, the air - outlet device of the present application can separately control the movements of different vane systems only through the movement of a single control component in multiple directions, so that the movements of each vane system are independent of each other and do not interfere with each other.

[0061] Second, in the first embodiment of the present application, the setting structure of the control component and the sliding shaft enables the sliding of the control component on the sliding shaft not to additionally increase the space occupied by the driving component during the driving process, which is beneficial to the compact layout of the air - outlet device.

[0062] Third, in the second embodiment of the present application, the arc-shaped tooth surface meshing structure can isolate the swinging movement of the gear in the direction perpendicular to the meshing transmission direction without affecting the meshing transmission of the gear.

[0063] Although the present application has been described in connection with examples of the embodiments outlined above, various alternative solutions, modifications, variations, improvements, and / or substantially equivalent solutions, whether known or now or soon foreseeable, may be apparent to those of at least ordinary skill in the art. Additionally, the technical effects and / or technical problems described in the present application are exemplary rather than restrictive; so the disclosure in the present application may be used to solve other technical problems and have other technical effects and / or may solve other technical problems. Therefore, the examples of the embodiments of the present application as stated above are intended to be illustrative rather than restrictive. Various changes can be made without departing from the spirit or scope of the present application. Accordingly, the present application is intended to cover all known or earlier developed alternative solutions, modifications, variations, improvements, and / or substantially equivalent solutions.
