Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically a hair dryer with a noise reduction structure. Background Technology

[0002] A hair dryer is a small electrical appliance that blows out hot air, mainly used for hairdressing to dry, flatten, or style hair. Hair dryers are mainly composed of an electric motor, fan blades, and heating elements. The working principle of a hair dryer is that the electric motor drives the fan blades to rotate, drawing in air and heating it through the heating elements before blowing it out. Users can control the status of the hair dryer through a switch, selecting hot air, cold air, or turning it off.

[0003] Application number CN222149289U discloses a hair dryer, including: a handle, a main housing, and an air outlet device. The handle is connected to the main housing, and the air outlet device is installed inside the main housing. The main housing has an air inlet and an air outlet, with the air inlet located at the rear end and the air outlet at the front end. The air outlet device includes a centrifugal fan and a return pipe. The centrifugal fan has an air inlet end and an air outlet end. The air inlet end is connected to the rear end of the return pipe and the air inlet, and the air outlet end is connected to the front end of the return pipe and the air outlet device. This utility model embodiment supplies air through a centrifugal fan. Utilizing the principle that the centrifugal fan compresses air and generates heat during high-speed operation, and with the help of the return pipe, a portion of the hot air blown out by the centrifugal fan is redirected back to the air inlet end, where it is compressed and heated again. This cycle repeats, gradually increasing the temperature of the hot air blown out by the centrifugal fan, achieving the effect of replacing electric heating wire and making the hair dryer more energy-efficient.

[0004] Existing technologies include components such as handles, main housings, and air outlets to achieve the function of blowing air. Hot air is compressed and heated by the high-speed rotation of a centrifugal fan and then blown out through an air outlet. However, the high-speed rotation of the fan during operation can easily generate a lot of noise, and dust and dirt can easily enter the air outlet, making it difficult to clean and affecting the efficiency of regular cleaning.

The handle structure 3 includes a mounting plate 301. The bottom of the mounting plate 301 is connected to the control panel 302, and the bottom of the control panel 302 is connected to the plug 303.

[0030] By installing sound-absorbing cotton 102 on both sides inside the unit structure 1, the noise generated during the operation of the blower is absorbed, thereby reducing the reflection and propagation of noise and thus reducing noise.

[0031] The outer shell 101 is cylindrical. The inner sides of the outer shell 101 are symmetrically provided with strip grooves. The sound-absorbing cotton 102 is fixedly installed inside the grooves. The center of the outer shell 101 is provided with an air guide 103. The left side of the air guide 103 is fixedly installed with a motor 105. The right side of the motor 105 is fixedly provided with several sets of heating wires 104. The heating wires 104 are distributed in a circumferential array at equal distances.

[0032] A housing 106 is fixedly fitted on the outside of the motor 105. A fan 107 is fixedly installed inside the housing 106. The bottom of the fan 107 is electrically connected to the motor 105 via a wire. An air guide cavity 108 is fixedly installed on the outside of the fan 107. One side of the heating wire 104 is movably connected to the sleeve 201 in the air outlet assembly 2. An air outlet assembly 2 with a replacement function is provided. An isolation plate 202 is movably connected inside the sleeve 201. The isolation plate 202 is an annular plate, and a fixing bracket 203 is fixedly fitted in the middle. The fixing bracket 203 is movably snapped onto the bottom of both sides of the air outlet plate 204. The bottom of the housing 101 is movably connected to the handle structure 3.
