AI Technical Summary
When used, existing hair dryers are in use, the disorder caused by the high-speed air flow contact with the shell leads to greater operating noise, which affects the rest of other members of the family.
A noise reduction mechanism including a wind guide housing and a closed loop is designed. The outside of the wind guide housing forms a noise reduction chamber with the closed loop, and a noise reduction filling layer is filled in the chamber to absorb vibration when air flows, thereby reducing noise.
Through the combination of the air guide shell and the noise reduction filling layer, the vibration during air circulation is effectively absorbed, which significantly reduces the noise during the operation of the hair dryer and improves the silent effect of the use environment.

DETAILED DESCRIPTION
[0018] 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.
[0019] See also Figure 1 to Figure 3In an embodiment of the utility model, a high-speed hair dryer with good noise reduction effect includes a shell 1, a handle 2 is integrally formed below the outer periphery of the shell 1, and a noise reduction mechanism is installed inside the shell 1; the noise reduction mechanism includes an air guide shell 6 fixedly installed in the inner cavity of the shell 1, the cross-section of the air guide shell 6 generally presents an "S"-shaped structure, the air guide shell 6 has an air outlet 7 at the air outlet position close to the shell 1, and the other end of the air guide shell 6 has an opening 14; the inner wall of the shell 1 is provided with an air guide cover 8 in the direction of the opening 14, the air guide cover 8 has a hollow cone structure, and the wide mouth edge of the air guide cover 8 is inserted into the inner cavity of the opening 14, dividing the opening 14 into an air inlet guide groove 10 located on the outside and an air outlet guide groove 11 located on the inside.
[0020] In this embodiment: first, after the device is powered on, the start button is pressed, and the fan starts to run. After being sucked in, the wind comes into contact with the wind guide cover 8, and the wind guide cover 8 guides the wind into the air inlet guide groove 10. The wind is discharged from the air outlet 7 along the inner side of the air guide shell 6. The air outlet 7 is located between the middle part of the air guide shell 6 and the outer periphery of the cone 15, thereby forming an effect of guiding the wind out.
[0021] Please refer to Figure 2 A rear shell 3 is integrally formed at the end of the outer shell 1, and the rear shell 3 has a porous structure.
[0022] In this embodiment: it is convenient for outside air to be sucked into the housing 1.
