[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specifically, the noise reduction blades 4 are driven to rotate by the motor 3. When the noise reduction blades 4 rotate, noise is generated. By changing the texture of the noise reduction blades 4, these textures help break the vortex formed by the airflow, thereby reducing the noise generated by the turbulent airflow. By adding a sound-absorbing wedge 5 on the surface of the inner shell 1, the small hole structure of the sound-absorbing wedge 5 can allow sound waves to enter the inside of the material, thereby effectively reducing the reflection of the sound waves. The kinetic energy generated by the rotation of the noise reduction blades 4 drives the inner connecting plate 7 to move outward, causing the first spring 11 to be squeezed outward, and the first spring 11 is used to absorb and reduce vibrations through the rebound characteristics of the first spring 11. The inner connecting plate 7 moves outward, causing the first movable plate 9 to move outward through the movement of the second movable plate 10.

[0026] Reference Figure 1 - Figure 3 The shock absorbing assembly includes a telescopic rod 14, one end of which is rotatably connected to the outer wall of the inner shell 1, and the other end of the telescopic rod 14 is rotatably connected to the outer shell 13, and the outer wall of the outer shell 13 is fixedly connected to the outer wall of the outer connecting plate 6.

[0027] Specifically, the outer connecting plate 6 and the inner connecting plate 7 can be fixedly connected together through the telescopic rod 14 , and the telescopic rod 14 can adjust the distance along with the shaking of the noise reduction blade 4 .

[0028] Reference Figure 2 - Figure 4 The outer wall of the outer shell 13 is fixedly connected with a fixed slider 15, the lower surface of the inner shell 1 is arranged on the upper surface of the fixed slider 15, the interior of the fixed slider 15 is slidably connected with an adjusting plate 16, the inner wall of the fixed slider 15 is slidably connected with a serrated slide rail 17, one end of the adjusting plate 16 is slidably connected to the inner wall of the serrated slide rail 17, the interior of the adjusting plate 16 is slidably connected with a connecting rod 19, one end of the connecting rod 19 is fixedly connected with a connecting block 18, the upper surface of the connecting block 18 is fixedly connected to the outer wall of the fixed slider 15, the outer wall of the connecting block 18 is fixedly connected with a second spring 20, one end of the second spring 20 is fixedly connected to the outer wall of the adjusting plate 16, and the inner wall of the second spring 20 is arranged on the outer wall of the connecting rod 19.

[0029] Specifically, by pressing the adjustment plates 16 on both sides inward to make the serrations of the adjustment plates 16 move inward, the adjustment plates 16 can be adjusted to slide above the serration rails 17. The rebound characteristics of the second spring 20 make the serrations of the adjustment plates 16 stuck above the serration rails 17, so that the cooling fan can be fixed and installed.

[0030] Working principle: When a DC cooling fan for an induction cooker is needed, the noise reduction blade 4 is first driven to rotate by the motor 3. When the noise reduction blade 4 rotates, noise is generated. By changing the texture of the noise reduction blade 4, these textures help break the vortex formed by the airflow, reducing the noise generated by the turbulent airflow. By adding a sound-absorbing wedge 5 on the surface of the inner shell 1, the small hole structure of the sound-absorbing wedge 5 can allow sound waves to enter the interior of the material, thereby effectively reducing the reflection of sound waves. The kinetic energy generated by the rotation of the noise reduction blade 4 drives the inner connecting plate 7 to move outward to make the first A spring 11 is pressed outward, and the vibration is absorbed and reduced by the rebound characteristic of the first spring 11. The outer connecting plate 6 and the inner connecting plate 7 can be fixedly connected together through the telescopic rod 14, and the telescopic rod 14 can adjust the distance with the shaking of the noise reduction blade 4. The saw teeth of the adjusting plate 16 are moved inward by pressing the adjusting plates 16 on both sides inward, so that the adjustment plate 16 can be adjusted to slide above the sawtooth slide rail 17. The saw teeth of the adjusting plate 16 are stuck above the sawtooth slide rail 17 through the rebound characteristic of the second spring 20, so that the cooling fan can be fixed and installed.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
