[0022] Figure 5 for Figure 2 A centrifugal fan with the function of adjusting the air outlet direction comprises: a mounting plate 1, a fan 2 is mounted inside the mounting plate 1, a duct 3 is fixedly connected to the fan 2, a steering mechanism 4 is arranged on the duct 3, an adjusting plate 5 is arranged on the steering mechanism 4, a fixing groove 11 is provided on the adjusting plate 5, an arc groove 12 is provided on the adjusting plate 5, a plurality of limiting grooves 13 are provided inside the arc groove 12, a bellows 6 is fixedly connected to the duct 3, an air port 7 is fixedly connected to the bellows 6, a fixing column 8 is fixedly connected to the duct 3, a lever 9 is fixedly connected to the air port 7, a steering spring 10 is fixedly connected between the lever 9 and the fixing column 8, and the centrifugal fan can change the air outlet direction without moving the fan body, so that the user can flexibly adjust the airflow direction according to actual needs to adapt to different working scenes.

[0023] The fan 2 is provided with a mounting mechanism 14, and the mounting mechanism 14 is provided with a mounting groove 15. A mounting spring 16 is fixedly connected inside the mounting groove 15, and a limiting plate 17 is fixedly connected to the other end of the mounting spring 16. A limiting column 18 is fixedly connected to the limiting plate 17, and a limiting thread 19 is provided on the surface of the limiting column 18. A fixing block 20 is fixedly connected to the fan 2, and a fixing bolt 21 is threadedly connected to the limiting column 18. A stabilizing groove block 29 is fixedly connected to the mounting plate 1. When installing the fan 2, it is only necessary to move the fan 2 vertically downward, and the bottom of the fan 2 is placed on the stabilizing groove block 29. When moving downward, since the top of the limiting column 18 is an arc shape, it can be retracted into the mounting groove 15. When installed to the specified position, the limiting column 18 extends out, and the fixing bolt 21 makes the fan 2 firmly mounted on the mounting plate 1 through the limiting thread 19, and the fixing block 20 controls the path of the fan 2 when it moves downward.

[0024] The material of the bellows 6 is polyethylene, the steering spring 10 is a tension spring, and the bellows 6 is a tubular elastic element that can be deformed to a certain extent in the axial, transverse or bending directions.

[0025] A rotating plate 22 is fixedly connected to the bottom of the mounting plate 1 , and a fixed plate 23 is rotatably connected to the bottom of the rotating plate 22 . The rotating plate 22 can drive the entire mounting plate 1 to rotate.

[0026] A plurality of plug-in slots 24 are formed inside the fixing plate 23 . Plug-in rods 25 are inserted into the plug-in slots 24 . The plug-in rods 25 are matched with the plug-in slots 24 .

[0027] A lifting plate 26 is fixedly connected to the top of the plug-in rod 25, a rebound plate 27 is fixedly connected to the middle of the surface of the plug-in rod 25, a return spring 28 is fixedly connected to the bottom of the rebound plate 27, and the other end of the return spring 28 is fixedly connected to the rotating plate 22. When it is necessary to achieve universal adjustment of the air outlet direction of the fan 2, it is only necessary to pull up the lifting plate 26 to make the plug-in rod 25 leave the plug-in slot 24, and then rotate the rotating plate 22 to change the horizontal direction of the fan 2, and the air outlet direction of the air port 7 will also change accordingly, thereby achieving universal adjustment of the air outlet direction of the fan 2.

[0028] The working principle of a centrifugal fan with the function of adjusting the air outlet direction provided by the utility model is as follows:

[0029] When the fan 2 is working, if the air outlet direction of the fan 2 needs to be adjusted due to work needs, it is only necessary to pull the lever 9 to make it slide in the limiting groove 13 until it moves into the arc groove 12, and then push the lever 9 to slide inside the arc groove 12 to achieve the desired air outlet angle, and release the lever 9. Since the steering spring 10 is a tension spring, after the lever 9 is released, the tension spring drives the lever 9 to slide into the nearest limiting groove 13 to form a constraint, so that the structure can be stable after the air outlet direction is changed.

[0030] Compared with the related art, the centrifugal fan with the function of adjusting the air outlet direction provided by the utility model has the following beneficial effects:

The easy installation feature of the fan 2 reduces the installation difficulty, reduces the dependence on professional skills, facilitates the deployment of equipment, and facilitates user use.
