DETAILED DESCRIPTION

[0036] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Embodiment 1,

[0040] like Figure 1 A double air guide plate device as shown in FIG. 6 includes a first air guide plate 10, a second air guide plate 20 and a driving assembly. The driving assembly includes a driving member 31, a linkage mechanism, a swing member 32, a first transmission shaft 34 and a second transmission shaft 35, one end of the swing member 32 is connected to the first air guide plate 10, and the other end of the swing member 32 is connected to the first transmission shaft 34 and the second transmission shaft 35.

[0041] Specifically, the first transmission shaft 34 is synchronously connected to the driving member 31 through a linkage mechanism, and after being synchronously connected to the driving member 31 , the first transmission shaft 34 drives the swing member 32 to rotate, thereby driving the first air guide plate 10 to rotate.

[0042] In addition, the second transmission shaft 35 is connected to the second air guide plate 20; the linkage mechanism can guide the second transmission shaft 35 to be synchronously connected or asynchronously connected to the driving member 31. When the second transmission shaft 35 is synchronously connected to the driving member 31, the second transmission shaft 35 can drive the second air guide plate 20 to rotate, and the second transmission shaft 35 is in a non-rotating state when it is used to be asynchronously connected to the driving member 31. It should be noted that in this embodiment, the asynchronous connection between the driving member 31 and the second transmission shaft 35 means that the rotation of the driving shaft of the driving member 31 cannot drive the second transmission shaft 35 to rotate.

[0043] On the basis of the above structure, when the double air guide plate device of the present invention is used, the double air guide plate device can be applied to structures that require air outlet guidance, such as air conditioners, air conditioning fans, humidifiers, and blowers. Specifically, in this embodiment, the double air guide plate structure can be applied to the air outlet of the air conditioner as an example.

[0044] An air outlet channel is arranged on the air conditioner host 40, and a first air outlet and a second air outlet can be respectively arranged on two adjacent surfaces of the air outlet channel. The first air outlet can guide the airflow to be discharged along a first direction, and the second air outlet can guide the airflow to be discharged along a second direction. In the present embodiment, the above-mentioned two adjacent surfaces can be a vertical air outlet surface and a horizontal air outlet surface. The first air outlet is arranged on the vertical air outlet surface for guiding the airflow to be discharged along a horizontal direction (first direction), and the second air outlet is arranged on the horizontal air outlet surface for guiding the airflow to be discharged along a vertical direction (second direction).

[0045] Based on the above structure, in the initial state, see Figure 1 The first air guide plate 10 is closed at the first air outlet position, and the second air guide plate 20 is closed at the second air outlet position. When the above-mentioned driving component is set, the above-mentioned first air guide plate 10 and the second air guide plate 20 are rotated and switched, and have the following usage states:

[0046] The first use state, see Figure 2 ,

[0047] Start the driving member 31 and the driving shaft of the driving member 31 rotates. The rotation of the driving shaft of the driving member 31 can drive the first transmission shaft 34 to rotate through the linkage mechanism. The rotation of the first transmission shaft 34 can drive the swing member 32 to rotate. The rotation of the swing member 32 can drive the first air guide plate 10 connected thereto to rotate. At this time, the second transmission shaft 35 is in an asynchronous state with the driving shaft of the driving member 31 under the guidance of the linkage mechanism, that is, the second transmission shaft 35 does not rotate at this time, and the second air guide plate 20 covers the second air outlet, that is, in this usage state, the first air guide plate 10 opens the first air outlet, and the second air guide plate 20 covers the air outlet. The air outlet angle of the first air outlet can be adjusted during the rotation of the first air guide plate 10.

[0048] During the first usage state, the driving shaft of the driving member 31 rotates continuously. After the linkage mechanism drives the first transmission shaft 34 to rotate to the first air guide plate 10 to be fully opened, the first air guide plate 10 and the second air guide plate 20 are connected to each other on the horizontal plane. The airflow after cooling or heating in the air conditioner can be guided to the first air outlet through the second air guide plate 20 and the first air guide plate 10, thereby extending the air guide path and making the airflow more stable.

[0049] In addition, since the first air guide plate 10 is connected to one end of the swing member 32, and the second air guide plate 20 is connected to the second transmission shaft 35 at the other end of the swing member 32, and the first air guide plate 10 located at one end of the swing member 32 is rotated by the first transmission shaft 34 at the other end of the swing member 32, that is, after the first air guide plate 10 is opened to a horizontal state, it and the second air guide plate 20 are located at both ends of the swing member 32, so the first air guide plate 10 and the second air guide plate 20 are stepped to guide the air, that is, double-layer air guiding can be achieved. The airflow in the air conditioner main unit 40 is discharged horizontally along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower height, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the derived airflow can be doubled, and at the same time, after the airflow is sent out in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is farther.

[0050] The second usage state, see Figure 2 ,

[0051] During the first usage state, the driving shaft of the driving member 31 continues to rotate. After the linkage mechanism drives the first transmission shaft 34 to rotate to the first air guide plate 10 to be fully opened, the linkage mechanism can synchronously connect the second transmission shaft 35 with the driving shaft of the driving member 31, that is, the driving shaft of the driving member 31 can drive the first transmission shaft 34 and the second transmission shaft 35 to rotate. When the first transmission shaft 34 and the second transmission shaft 35 rotate, the first air guide plate 10 and the second air guide plate 20 can be driven to rotate at the same time. At this time, the first air guide plate 10 and the second air guide plate 20 are connected to each other on the same plane, the air guide path is longer, and the air supply distance is farther.

[0052] And the rotation of the second air guide plate 20 can open the second air outlet. When the second air outlet is opened, the air flow in the air-conditioning host 40 can be partially discharged through the second air outlet and partially discharged through the first air outlet, that is, air flow is discharged in both the horizontal direction and the vertical direction. According to the different angles at which the first air guide plate 10 and the second air guide plate 20 are rotated at the same time, the air volume of the first air outlet or the second air outlet can be adjusted to achieve air volume adjustment in different directions.

[0053] Similarly, since the first air guide plate 10 and the second air guide plate 20 are located at the two ends of the swing member 32 after being fully opened, the first air guide plate 10 and the second air guide plate 20 guide the air in a stepped manner, that is, double-layer air guidance can be achieved. The airflow in the air conditioner main unit 40 is discharged along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower height, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the output airflow can be doubled, and at the same time, after the airflow is sent in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is farther.

[0054] The third use state, see Figure 3 ,

[0055] During the continued rotation of the driving member 31, the second air guide plate 20 rotates from the second air outlet to close the first air outlet, and the first air guide plate 10 rotates from the first air outlet to below the first air outlet. At this time, the second air guide plate 20 closes the first air outlet, and the first air guide plate 10 is located on the side of the second air outlet and is in a vertical air guiding state with the second air guide plate 20. At this time, the airflow in the air-conditioning host 40 is discharged vertically along the second air guide plate 20 and the first air guide plate 10, and is in a vertical air outlet state.

[0056] Similarly, since the first air guide plate 10 and the second air guide plate 20 are located at the two ends of the swing member 32 after being fully opened, the first air guide plate 10 and the second air guide plate 20 guide the air in a stepped manner, that is, double-layer air guidance can be achieved. The airflow in the air conditioner main unit 40 is discharged vertically along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower step, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the output airflow can be doubled, and at the same time, after the airflow is sent out in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is longer.

[0057] Embodiment 2,

[0058] Further, see Figure 4 The linkage mechanism in this embodiment includes a linkage gear 33, a first gear 36 and a second gear 37. The first gear 36 is arranged on the first transmission shaft 34, and the second gear 37 is arranged on the second transmission shaft 35. The linkage gear 33 is provided with a first tooth segment 331 and a second tooth segment in its own axial direction. The first tooth segment 331 is meshed with the first gear 36. The second tooth segment is provided with a meshing segment 333 and a toothless segment 332. The meshing segment 333 and the toothless segment 332 are distributed sequentially in the circumferential direction of the second tooth segment; the meshing segment 333 can mesh with the second gear 37 to drive the second transmission shaft 35 to rotate, and the toothless segment 332 can slide with the second gear 37.

[0059] Based on this structure, when the linkage mechanism in this embodiment is used,

[0060] In the first use state of the above-mentioned embodiment 1, the driving shaft of the driving member 31 can drive the linkage gear 33 to rotate, and the first tooth segment 331 of the linkage gear 33 can be meshed with the first gear 36 for transmission. At this time, the toothless segment 332 of the second tooth segment can slide with the second gear 37 because it has no tooth segment, and cannot drive the second transmission shaft 35 to rotate, so the second transmission shaft 35 is in a non-rotating state. During the rotation of the linkage gear 33, the first gear 36 can always be driven to rotate, so the rotation of the driving shaft of the driving member 31 can drive the first transmission shaft 34 to rotate all the time.

[0061] When the dual air guide plate device switches from the first usage state to the second usage state and the third usage state, the linkage gear 33 continues to rotate driven by the driving shaft of the driving member 31, and the toothless section 332 of the second tooth segment of the linkage gear 33 rotates to be staggered with the second gear 37. At this time, the meshing section 333 of the second tooth segment meshes with the second gear 37, thereby driving the second transmission shaft 35 to rotate, and then driving the second air guide plate 20 connected to the second transmission shaft 35 to rotate. In this process, the first gear 36 of the first transmission shaft 34 always maintains a meshing state with the first tooth segment 331, so that the first air guide plate 10 and the second air guide plate 20 are in a synchronous rotation state.

[0062] Embodiment 3,

[0063] Further, based on the structures of Example 1 and Example 2, see Figure 4 , a third gear 39 may be further provided on the second transmission shaft 35, the swinging member 32 is connected to the first air guide plate 10 through the rotating shaft 38, a fourth gear 381 may be provided on the rotating shaft 38, and the third gear 39 is meshed with the fourth gear 381. Based on this structure, in the first use state, the first transmission shaft 34 is connected to one end of the swinging member 32 and drives the swinging member 32 to rotate, and drives the swinging member 32 to rotate. The swinging member 32 rotates, which can drive the rotating shaft 38 connected to the swinging member 32 to rotate, and the rotating shaft 38 rotates, which can drive the fourth gear 381 to rotate. At this stage, the second transmission shaft 35 does not rotate, and the third gear 39 connected to the second transmission shaft 35 does not rotate. The meshing of the fourth gear 381 and the third gear 39 causes the fourth gear 381 to rotate around its own axis during the revolution, so the rotation speed of the first air guide plate is superimposed, and the rotation speed of the first air guide plate is faster.

[0064] In the second and third usage states, the first transmission shaft 34 and the second transmission shaft 35 rotate under the guidance of the linkage mechanism. When the second transmission shaft 35 rotates, the first transmission shaft and the second transmission shaft rotate synchronously. At this time, the third gear 39 connected to the second transmission shaft moves synchronously with the swinging member 32 synchronously connected to the first transmission shaft. Therefore, the rotating shaft 38 rotates synchronously with the second transmission shaft, and the third gear and the fourth gear will not produce relative rotation, and the synchronization is better.

[0065] Embodiment 4,

[0066] Based on the above-mentioned Embodiment 1 and Embodiment 2, in this embodiment, see Figure 5The first transmission shaft 34 may be provided with a third gear 39, and the third gear 39 may be rotatably connected to the first transmission shaft, that is, the third gear 39 may rotate relative to the first transmission shaft. The swing member 32 is connected to the first air guide plate 10 via a rotating shaft 38, and a fourth gear 381 is provided on the rotating shaft 38, and the third gear 39 meshes with the fourth gear 381.

[0067] Based on this structure, whether in the first, second or third use state, when the linkage mechanism guides the first transmission shaft 34 to rotate, the first gear 36 at one end of the first transmission shaft 34 meshes with the first tooth segment 331 of the linkage mechanism for transmission, and the other end of the first transmission shaft 34 drives the swing member 32 to rotate. The shaft 38 at the other end of the swing member 32 can drive the first air guide plate 10 to rotate, and the third gear 39 meshes with the fourth gear 381. At this time, the third gear 39 has self-rotation and can drive the fourth gear 381 meshed with it to rotate to realize revolution, so that multiple transmission ratios can be achieved, and the rotation speed of the first air guide plate 10 is faster. Example 5,

[0068] Furthermore, based on the structures of the above-mentioned embodiments 3 and 4, the swing member 32 includes a swing shell and a swing cover plate, a transmission cavity is provided in the swing shell, the third gear 39 and the fourth gear 381 are both installed in the transmission cavity, and the swing cover plate is sealed in the transmission cavity.

[0069] In this way, when assembling the gears of the first transmission shaft 34, the rotating shaft 38 and the fourth gear 381, the swing cover of the swing member 32 can be opened, and then the gears of the first transmission shaft 34, the rotating shaft 38 and the fourth gear 381 are assembled to the transmission cavity of the swing housing, and then the swing cover is closed, so that it is convenient to disassemble and repair the gears. The third gear 39 and the fourth gear 381 are located in the transmission cavity, which reduces the damage to the gears caused by the cold air or hot air inside the air conditioner during use.

[0070] Further, the first transmission shaft 34 is inserted into the second transmission shaft 35, so that the first transmission shaft 34 and the second transmission shaft 35 are coaxially arranged, compared with the staggered arrangement of the first transmission shaft 34 and the second transmission shaft 35, the first transmission shaft 34 and the second transmission shaft 35 are coaxially arranged, in the first use state, the first air guide plate 10 rotates around the axis of the first transmission shaft 34 and the second transmission shaft 35, in the second use state and the third use state, when the first air guide plate 10 and the second air guide plate 20 rotate synchronously, the first air guide plate 10 and the second air guide plate 20 also rotate around the same axis, compared with the staggered arrangement of the first transmission shaft 34 and the second transmission shaft 35, the interference between the shafts is reduced, and the rotation range is larger. On the basis of the above structure, the first gear 36 is arranged at the end of the first transmission shaft 34 extending from the second transmission shaft 35.

[0071] After the first transmission shaft is passed through the second transmission shaft, in the above-mentioned embodiment 4, in order to facilitate the rotatable installation of the third gear and the first transmission shaft, a connecting shaft can be provided on the third gear, and the connecting shaft can rotatably pass through the first transmission shaft and be connected to the air-conditioning main unit, that is, the axis of rotation of the fourth gear revolves around the axis of the first transmission shaft.

[0072] Embodiment 6,

[0073] Further, based on the above-mentioned embodiment 1 and embodiment 2, see Figure 6 In this embodiment, there are two linkage gears 33, and one of the linkage gears 33 is synchronously connected with the first gear 36 and forms a first tooth segment 331, while the other linkage gear 33 is provided with a meshing segment 333 and a toothless segment 332 in its own axial direction and forms a second tooth segment.

[0074] Different from the second embodiment, the first tooth segment 331 and the second tooth segment in the second embodiment are arranged on different segments of the same linkage gear 33, while the first tooth segment 331 and the second gear 37 in the present embodiment are formed by two linkage gears 33. In this way, the linkage gear 33 formed as the first tooth segment 331 is connected to the first transmission shaft 34, and the linkage gear 33 formed as the second tooth segment is meshed or slidably matched with the second gear 37 of the second transmission shaft 35.

[0075] Based on this structure, in the first usage state, the driving shaft of the driving member 31 can drive the two interlocking gears 33 to rotate, one of the interlocking gears 33 rotates with the first gear 36 of the first transmission shaft 34, and the toothed section 332 of the other interlocking gear 33 can be staggered with the second gear 37 of the second transmission shaft 35. At this time, the first transmission shaft 34 rotates, and the second transmission shaft 35 does not move.

[0076] In the first and third usage states, the driving shaft of the driving member 31 can drive the two linkage gears 33 to rotate, one of the linkage gears 33 rotates with the first gear 36 of the first transmission shaft 34, and the meshing section 333 of the other linkage gear 33 can mesh and transmit with the second gear 37 of the second transmission shaft 35. At this time, the first transmission shaft 34 and the second transmission shaft 35 rotate simultaneously.

[0077] Furthermore, there are two swing members 32, and each swing member 32 is provided with a rotating shaft 38, wherein the rotating shaft 38 of one swing member 32 is connected to the first air guide plate 10, and the rotating shaft 38 of the other swing member 32 is connected to the second air guide plate 20, and the driving assembly further includes a third transmission shaft 391, which can be connected to the two swing members 32 along its own axis at one time and rotate with the swing members 32. A third gear 39 can be provided at the part where the third transmission shaft 391 is connected to the two swing members 32, and a fourth gear 381 is provided on the rotating shaft 38 of each swing member 32, and the third gear 39 is meshed with the fourth gear 381.

[0078] The first transmission shaft 34 extends along its own axis and is connected to the swing member 32 ; the second transmission shaft 35 passes through the two swing members 32 along its own axis and is fixedly connected to the swing member 32 connected to the second air guide plate 20 .

[0079] Based on the above structure,

[0080] In the first usage state, the linkage gear meshing with the first gear 36 rotates, driving the first transmission shaft 34 connected thereto to rotate. The rotation of the first transmission shaft 34 can drive the swing member 32 connected thereto to rotate, and can drive the rotating shaft 38 at the other end of the swing member 32 to rotate. The rotation of the rotating shaft 38 can drive the fourth gear 381 to revolve around the third gear 39 in the swing member 32, thereby driving the rotating shaft 38 to revolve around the axis of the third transmission shaft 391. At the same time, the third gear 39 and the fourth gear 381 are meshed, so that the fourth gear 381 rotates around its own axis, and the rotation speed of the first air guide plate 10 connected to the corresponding rotating shaft 38 is superimposed, and the rotation speed is faster.

[0081] At this time, the second gear 37 on the second transmission shaft 35 is meshed with the toothless segment 332 of another linkage gear and is in a non-rotating rotation.

[0082] In the second and third use states, the linkage gear meshing with the first gear 36 rotates, driving the first transmission shaft 34 connected thereto to rotate, and the second gear 37 on the second transmission shaft 35 meshes with the meshing section 333 of another linkage gear, thereby driving the second transmission shaft 35 to rotate. At this time, the first transmission shaft 34 can drive the swinging member 32 connected thereto to rotate, and the rotation of the second transmission shaft 35 can drive the swinging member 32 connected thereto to rotate. When each swinging member 32 rotates, the fourth gear 381 on the corresponding rotating shaft 38 can mesh with the third gear 39 at the corresponding position on the third transmission shaft 391 for transmission, that is, when the two swinging members 32 rotate, the fourth gear 381 revolves around the third gear 39 at the corresponding position, thereby driving the rotating shaft 38 to revolve around the axis of the third transmission shaft 391. At the same time, the third gear 39 meshes with the fourth gear 381, so that the fourth gear 381 rotates around its own axis, and the rotation speeds of the first air guide plate 10 and the second air guide plate 20 connected to the corresponding rotating shaft 38 are superimposed, and the rotation speed is faster.

[0083] Of course, in the present embodiment, the first air guide plate 10 and the second air guide plate 20 are both rotated by the swinging member 32, and the first air guide plate 10 and the second air guide plate 20 are respectively connected to the ends of the two swinging members 32 that are away from each other. Therefore, after the first air guide plate 10 and the second air guide plate 20 are fully opened, it is easier to form a stepped double-layer air guide structure, and the height difference is larger than that of the structure with one swinging member 32. Therefore, the layered effect of the double-layer air guide structure formed is more obvious, and the staggered air flow is larger.

[0084] Further,

[0085] Furthermore, the third transmission shaft 391 is rotatably inserted into the first transmission shaft 34, and the second transmission shaft 35 is rotatably inserted into the third transmission shaft 391, and is fixedly connected to the swing member 32 connected to the second air guide plate 20. In this way, the first transmission shaft 34, the second transmission shaft 35 and the third transmission shaft 391 are all coaxially arranged. The first transmission shaft 34, the second transmission shaft 35 and the third transmission shaft 391 are coaxially arranged. In the first use state, the first air guide plate 10 rotates around the axis of the first transmission shaft 34 and the second transmission shaft 35. In the second use state and the third use state, when the first air guide plate 10 and the second air guide plate 20 rotate synchronously, the first air guide plate 10 and the second air guide plate 20 also rotate around the same axis. Compared with the staggered arrangement of the first transmission shaft 34 and the second transmission shaft 35, the interference between the shafts is reduced, and the rotation range is larger.

[0086] Similarly, in this embodiment, the swing member 32 includes a swing housing and a swing cover plate, a transmission cavity is provided in the swing housing, the third gear 39 and the fourth gear 381 are both installed in the transmission cavity, and the swing cover plate covers the transmission cavity.

[0087] In this way, when assembling the gears of the first transmission shaft 34, the rotating shaft 38 and the fourth gear 381, the swing cover of the swing member 32 can be opened, and then the gears of the first transmission shaft 34, the rotating shaft 38 and the fourth gear 381 are assembled to the transmission cavity of the swing housing, and then the swing cover is closed, so that it is convenient to disassemble and repair the gears. The third gear 39 and the fourth gear 381 are located in the transmission cavity, which reduces the damage to the gears caused by the cold air or hot air inside the air conditioner during use.

[0088] Embodiment 7,

[0089] This embodiment provides an air conditioner. Figure 1 -9, including,

[0090] The air conditioner host 40 is provided with a first air outlet and a second air outlet, the first air outlet is used to guide the airflow to be discharged along a first direction; the second air outlet is used to guide the airflow to be discharged along a second direction; the first direction and the second direction intersect;

[0091] The double air guide plate device comprises a first air guide plate 10 installed at the first air outlet to close or open the first air outlet; and a second air guide plate 20 installed at the second air outlet to close or open the second air outlet.

[0092] An air outlet channel is arranged on the air conditioner host 40, and a first air outlet and a second air outlet can be respectively arranged on two adjacent surfaces of the air outlet channel. The first air outlet can guide the airflow to be discharged along a first direction, and the second air outlet can guide the airflow to be discharged along a second direction. In the present embodiment, the above-mentioned two adjacent surfaces can be a vertical air outlet surface and a horizontal air outlet surface. The first air outlet is arranged on the vertical air outlet surface for guiding the airflow to be discharged along a horizontal direction (first direction), and the second air outlet is arranged on the horizontal air outlet surface for guiding the airflow to be discharged along a vertical direction (second direction).

[0093] Based on the above structure, in the initial state, see Figure 7 The first air guide plate 10 is closed at the first air outlet position, and the second air guide plate 20 is closed at the second air outlet position. When the above-mentioned driving component is set, the above-mentioned first air guide plate 10 and the second air guide plate 20 are rotated and switched, and have the following usage states:

[0094] The first use state, see Figure 8 ,

[0095] Start the driving member 31 and the driving shaft of the driving member 31 rotates. The rotation of the driving shaft of the driving member 31 can drive the first transmission shaft 34 to rotate through the linkage mechanism. The rotation of the first transmission shaft 34 can drive the swing member 32 to rotate. The rotation of the swing member 32 can drive the first air guide plate 10 connected thereto to rotate. At this time, the second transmission shaft 35 is in an asynchronous state with the driving shaft of the driving member 31 under the guidance of the linkage mechanism, that is, the second transmission shaft 35 does not rotate at this time, and the second air guide plate 20 covers the second air outlet, that is, in this usage state, the first air guide plate 10 opens the first air outlet, and the second air guide plate 20 covers the air outlet. The air outlet angle of the first air outlet can be adjusted during the rotation of the first air guide plate 10.

[0096] During the first usage state, the driving shaft of the driving member 31 rotates continuously. After the linkage mechanism drives the first transmission shaft 34 to rotate to the first air guide plate 10 to be fully opened, the first air guide plate 10 and the second air guide plate 20 are connected to each other on the horizontal plane. The airflow after cooling or heating in the air conditioner can be guided to the first air outlet through the second air guide plate 20 and the first air guide plate 10, thereby extending the air guide path and making the airflow more stable.

[0097] In addition, since the first air guide plate 10 is connected to one end of the swing member 32, and the second air guide plate 20 is connected to the second transmission shaft 35 at the other end of the swing member 32, and the first air guide plate 10 located at one end of the swing member 32 is rotated by the first transmission shaft 34 at the other end of the swing member 32, that is, after the first air guide plate 10 is opened to a horizontal state, it and the second air guide plate 20 are located at both ends of the swing member 32, so the first air guide plate 10 and the second air guide plate 20 are stepped to guide the air, that is, double-layer air guiding can be achieved. The airflow in the air conditioner main unit 40 is discharged horizontally along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower height, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the derived airflow can be doubled, and at the same time, after the airflow is sent out in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is farther.

[0098] The second usage state, see Figure 8 ,

[0099] During the first usage state, the driving shaft of the driving member 31 continues to rotate. After the linkage mechanism drives the first transmission shaft 34 to rotate to the first air guide plate 10 to be fully opened, the linkage mechanism can synchronously connect the second transmission shaft 35 with the driving shaft of the driving member 31, that is, the driving shaft of the driving member 31 can drive the first transmission shaft 34 and the second transmission shaft 35 to rotate. When the first transmission shaft 34 and the second transmission shaft 35 rotate, the first air guide plate 10 and the second air guide plate 20 can be driven to rotate at the same time. At this time, the first air guide plate 10 and the second air guide plate 20 are connected to each other on the same plane, the air guide path is longer, and the air supply distance is farther.

[0100] And the rotation of the second air guide plate 20 can open the second air outlet. When the second air outlet is opened, the air flow in the air-conditioning host 40 can be partially discharged through the second air outlet and partially discharged through the first air outlet, that is, air flow is discharged in both the horizontal direction and the vertical direction. According to the different angles at which the first air guide plate 10 and the second air guide plate 20 are rotated at the same time, the air volume of the first air outlet or the second air outlet can be adjusted to achieve air volume adjustment in different directions.

[0101] Similarly, since the first air guide plate 10 and the second air guide plate 20 are located at the two ends of the swing member 32 after being fully opened, the first air guide plate 10 and the second air guide plate 20 guide the air in a stepped manner, that is, double-layer air guidance can be achieved. The airflow in the air conditioner main unit 40 is discharged along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower height, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the output airflow can be doubled, and at the same time, after the airflow is sent in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is farther.

[0102] The third use state, see Fig. 9 ,

[0103] During the continued rotation of the driving member 31, the second air guide plate 20 rotates from the second air outlet to close the first air outlet, and the first air guide plate 10 rotates from the first air outlet to below the first air outlet. At this time, the second air guide plate 20 closes the first air outlet, and the first air guide plate 10 is located on the side of the second air outlet and is in a vertical air guiding state with the second air guide plate 20. At this time, the airflow in the air-conditioning host 40 is discharged vertically along the second air guide plate 20 and the first air guide plate 10, and is in a vertical air outlet state.

[0104] Similarly, since the first air guide plate 10 and the second air guide plate 20 are located at the two ends of the swing member 32 after being fully opened, the first air guide plate 10 and the second air guide plate 20 guide the air in a stepped manner, that is, double-layer air guidance can be achieved. The airflow in the air conditioner main unit 40 is discharged vertically along the second air guide plate 20, and part of the airflow is sent out in the direction of the first air guide plate 10 with a lower step, and the air conditioner achieves horizontal air discharge at two different heights; in this way, the output airflow can be doubled, and at the same time, after the airflow is sent out in the same direction through the first air guide plate 10 and the second air guide plate 20, the air supply distance is longer.

[0105] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
