Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present application.

[0025] Embodiment: refer to Figure 1-Figure 5 The electric hair dryer with the multi-stage noise reduction guide structure shown in the figure comprises an air duct shell 1 and a handle 17. The air duct shell 1 and the handle 17 are connected through a rotating connecting block 18. The peripheral outer wall of the handle 17 is provided with a switch 19. A multi-stage noise reduction mechanism is arranged in the air duct shell 1. The multi-stage noise reduction mechanism is used for noise reduction treatment of the noise generated during work, thereby improving the use comfort.

[0026] A rear end cover 9 is provided at one end of the wind cylinder shell 1, and a first noise reduction component is provided in the rear end cover 9. A motor seat 2 is provided on the inner wall of the circumference of the wind cylinder shell 1, and the motor seat 2 extends into the rear end cover 9 and is provided with a second noise reduction component. The motor seat 2 is fixedly provided with a motor 3 through a third noise reduction component.

A mica tube 8 is provided in the wind cylinder shell 1, and a mica frame 6 is provided on the inner wall of the mica tube 8. A heating wire and a fuse 7 are provided on the mica frame 6. A mesh cover 15 is provided on the inner wall of the circumference of the other end of the wind cylinder shell 1, and a fifth noise reduction component is provided on the outer wall of the circumference of the wind cylinder shell 1.

[0027] With the above structure, when in use, when the hair dryer is working, air enters through the first noise reduction component on the rear end cover, and under the joint action of multiple noise reduction components, the noise reduction function is realized. After the air is heated by the heating wire on the mica frame 6, it is blown out through the fifth noise reduction component to realize the blowing function.

[0028] like Figure 2 As shown, the first noise reduction component includes a plurality of air inlet holes 10. Through the dense arrangement of the plurality of air inlet holes 10, the air can be divided into several air ducts to enter, thereby reducing wind noise. The rear end cover 9 is a hemispherical design, and the plurality of air inlet holes 10 are all arranged on the inner wall of the circumference of the rear end cover 9. The plurality of air inlet holes 10 are all honeycomb-shaped.

[0029] Specifically, when the motor 3 drives the fan blades 4 to inhale air, the air is divided into several air ducts and enters through the multiple air inlet holes 10 on the rear end cover 9, thereby reducing the wind noise generated by the air flow. By setting the air inlet holes to a honeycomb shape, part of the fluctuation energy can be absorbed when the gas fluctuates, further reducing the noise.

[0030] like Figure 3 and Figure 4 As shown, the second noise reduction component includes two groups of air guide ports 11 and two groups of air guide vanes 12.

Through the arrangement of the air guide ports 11, the air will not hit the peripheral inner wall of the motor base 2 after entering the rear end cover 9, and will flow quickly through the air guide ports 11, thereby reducing the impact of the air on the inner wall of the motor base 2 during flow. The two groups of air guide ports 11 are respectively adapted to the two groups of air guide vanes 12.

[0031] Specifically, when the air flows into the rear end cover 9, it will flow horizontally and hit the inner wall of the motor base 2.

The mounting base is connected to the mica frame 6 through a connecting unit, and the connecting unit includes a plurality of self-tapping screws 14. The circumferential outer wall of the mounting base is provided with a plurality of threaded grooves, and the mica frame 6 is provided with a plurality of threaded holes. The plurality of self-tapping screws 14 are respectively provided in the plurality of threaded grooves and the plurality of threaded holes.

[0033] Specifically, by arranging the air guide bracket 13 at an angle, the air can be guided to flow in an S-shape, thereby dispersing the noise to various parts and reducing the noise.

[0034] like Figure 4 As shown, the fourth noise reduction component includes multiple fixed airfoils 5. Through the setting of the fixed airfoils 5, the air flow can be made more stable. A circular plate is fixedly provided on the output shaft of the motor base 2. The multiple fixed airfoils 5 are all provided on one side of the circular plate. The multiple fixed airfoils 5 are all adapted to the fan blades 4.

[0035] Specifically, by providing a plurality of wind-fixing wings 5 ​​, the stability of air flow can be improved and wind noise can be reduced.

[0036] like Figure 1 As shown, the fifth noise reduction component includes a guide flat nozzle 16. Through the setting of the guide flat nozzle 16, the circulating air can be guided out through its guide function, thereby improving the use effect. The inner wall of the guide flat nozzle 16 is provided with an external thread, and the outer wall of the air duct shell 1 is provided with an internal thread groove. The guide flat nozzle 16 is threadedly connected to the outer wall of the air duct shell 1.

[0037] Specifically, by providing the guide flat nozzle 16, the flowing air can be guided to the outside through the flat nozzle, while reducing wind noise, the air is flattened and blown out, thereby improving the use effect.
