[0049] The present invention is further described in conjunction with the following examples.

[0050] Example 1.

[0051] A pressure diffuser type air outlet device, such as Figure 1 to Figure 2 As shown, an air guide plate 100 is provided, and the inner surface of the air guide plate 100 is an air guide surface, and the air guide surface is a curved surface structure with a convex middle, and the air guide surface gradually transitions to the edge area from the center.

[0052] The wind blown out by the air outlet device gradually transitions from the center part along the inclined wall to the edge area through the curved wind guide surface, which can produce a horizontal wind outlet effect. At the same time, in conjunction with the air outlet channel, the direction of the wind outlet can be changed by changing the relative distance of the air guide plate 100.

[0053] Specifically, the air guide plate 100 is mounted at the air duct outlet, one end of the air duct outlet has a small diameter and the other end has a large diameter, and the end with the large diameter is where the airflow is discharged from the air duct. The air duct outlet continuously transitions from the end with the small diameter to the end with the large diameter.

[0054] The pressure-expanding air outlet device of the present invention is as follows: Figure 3 As shown, a main frame 200 for being assembled at the air duct outlet and a six-dimensional driving mechanism 300 are also provided, the air guide plate 100 is assembled on the main frame 200, the six-dimensional driving mechanism 300 is assembled between the main frame 200 and the air guide plate 100, and the six-dimensional driving mechanism 300 drives the air guide plate 100 to move in the front-back, left-right or up-down directions.

[0055] The six-dimensional driving mechanism 300 drives the air guide plate 100 to move in the front-to-back, left-to-right or up-and-down directions, resulting in a change in displacement direction. This can change the diffusion depth of the air guide plate 100 at the air outlet channel, thereby achieving the effect of changing the air outlet range.

[0056] It should be noted that the wind direction when the air flows out from the air duct outlet is defined as the front, and the wind direction when the air flows out in the opposite direction to the front is defined as the rear; the direction when the air outlet is blocked by the wind shield and moves to the left or right is defined as the left and right direction; the direction when the air outlet is blocked by the wind shield and moves upward or downward is defined as the up and down direction.

[0057] Furthermore, the main frame 200 is provided with an air duct interface for connecting to the air duct outlet, and the six-dimensional driving mechanism 300 is assembled on the air duct interface.

[0058] The six-dimensional driving mechanism 300 in this embodiment is provided with a support frame 340, a left-right driving mechanism 310, an up-down driving mechanism 330 and a front-back driving mechanism 320, and the left-right driving mechanism 310, the up-down driving mechanism 330 and the front-back driving mechanism 320 are respectively assembled on the support frame 340.

[0059] Specifically, Figure 4 As shown, the left and right driving mechanism 310 is provided with a first driving motor 311 and a first rotating wheel 312;

[0060] The first drive motor 311 is fixed to the air guide plate 100 , and the motor shaft of the first drive motor 311 is fixedly connected to the first rotating wheel 312 . The first drive motor 311 drives the first rotating wheel 312 to rotate. The support frame 340 is fixed with a first rack 341 , and the first rack 341 is meshed with the first rotating wheel 312 .

[0061] During the actual air outlet process, the first driving motor 311 rotates, driving the first rotating wheel 312 to rotate left and right on the first rack 341, thereby causing the air guide plate 100 to change its left and right displacement, thereby realizing the left and right air outlet modes to flap back and forth around the user, thereby improving the user's comfort.

[0062] In the diffuser-type air outlet device of the present invention, the left and right driving mechanisms 310 are further provided with limit wheels 313 , which are coaxially connected to the first rotating wheel 312 , and the radius of the limit wheel 313 is greater than the radius of the first rotating wheel 312 , and the limit wheel 313 fits the side wall of the first rack 341 .

[0063] It should be noted that the limiting wheel 313 is used to fit with the first rack 341 to ensure the stability of the first rotating wheel 312 during movement.

[0064] In this embodiment, the side of the wind deflector 100 close to the air duct outlet is the inner surface of the wind deflector, and the side of the wind deflector 100 facing away from the air duct outlet is the outer surface of the wind deflector. The first drive motor 311 can be fixed to the inner surface of the wind deflector, or the outer surface of the wind deflector, and the motor shaft of the first drive motor 311 passes through the through hole 110 provided on the wind deflector and is fixedly assembled with the first rotating wheel 312.

[0065] In this embodiment, the first drive motor 311 is fixedly mounted on the outer surface of the windshield. In actual design, those skilled in the art can set the position of the first drive motor 311 according to actual conditions, which will not be described in detail here.

[0066] Specifically, the support frame 340 is provided with a second fixed portion 342, front and rear sliding sleeves 343, front and rear sliding rods 344 and a third fixed portion 345, the front and rear sliding sleeves 343, the front and rear sliding rods 344, the second fixed portion 342 is fixed to the air duct outlet, the front and rear sliding sleeves 343 are fixedly connected to the second fixed portion 342, the front and rear sliding rods 344 are slidably assembled on the front and rear sliding sleeves 343, and the third fixed portion 345 is fixedly connected to the front and rear sliding rods 344.

[0067] Specifically, the front and rear driving mechanism 320 is provided with a second driving motor 321 and a second rotating wheel 322. The second driving motor 321 is fixed to the second fixed part 342, and the second driving motor 321 drives the second rotating wheel 322 to rotate. The second rotating wheel 322 is engaged with the second rack 3471 fixed to the third fixed part 345.

[0068] In the actual air outlet process, the second driving motor 321 fixed to the second fixed part 342 rotates, driving the second rotating wheel 322 shaft to rotate, so that the second rack 3471 meshing with the second rotating wheel 322 rotates back and forth, and when the second driving motor 321 drives the air guide plate 100 to move forward, the air duct outlet becomes wider, the wind speed of the air outlet gradually decreases, and the air is discharged along the edge area of ​​the air outlet, and finally tends to be discharged in a vertical direction; when the second driving motor 321 drives the air guide plate 100 to move backward, the air duct outlet becomes narrower, the wind speed of the air outlet is large, and the air is discharged along the air guide surface, and gradually tends to be discharged in a horizontal direction.

[0069] By moving the air guide plate 100 forward and backward, air supply coverage within a range of 180° in the air outlet direction is achieved, thereby achieving a swinging air outlet effect.

[0070] The support frame 340 of this embodiment is provided with an upper and lower sliding rod 346 and an upper and lower sliding sleeve 347 ; the third fixed portion 345 is fixedly connected to the upper and lower sliding sleeve 347 , and the third fixed portion 345 is slidably assembled on the upper and lower sliding sleeve 347 .

[0072] By rotating the third driving motor 331 fixed to the third fixed portion 345, the third rotating wheel 332 is driven to rotate, so that the third rack 3461 meshing with the third rotating wheel 332 moves up and down, and at the same time drives the upper and lower sliding rods 346 to move up and down, so as to realize the characteristics of hot air blowing downward and cold air blowing upward, thereby meeting the different needs of users.

[0073] The pressure-expanding air outlet device of the present invention is provided with an air guide plate 100, a main frame 200 for being assembled at the outlet of the air duct, and a six-dimensional driving mechanism 300. The inner surface of the air guide plate 100 is an air guide surface, which is a curved surface structure with a central protrusion, and the air guide surface gradually transitions from the center to the edge area, and the air guide plate 100 is assembled on the main frame 200, and the six-dimensional driving mechanism 300 is assembled between the main frame 200 and the air guide plate 100.

[0077] In this embodiment, two sets of left and right drive mechanisms 310 are provided, and the two sets of left and right drive mechanisms 310 are respectively arranged up and down and provided on the support frame 340. It should be noted that the two sets of left and right drive mechanisms 310 can simultaneously drive the first rotating wheel 312 to move left and right through the first driving motor 311, so that the wind guide plate 100 can be displaced in the left and right directions to generate comfortable wind.
