[0042] like Figure 2 , Figure 3 and Figure 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the control component 2 includes a first circuit board 21 and a second circuit board 22, the first circuit board 21 is arranged on the front shell 11, the second circuit board 22 is arranged on the rear shell 12, and the first circuit board 21 and the second circuit board 22 are built in the cold air chamber 101. By arranging the first circuit board 21 on the front shell 11 and the second circuit board 22 on the rear shell 12, the first circuit board 21 and the second circuit board 22 are arranged separately, which helps to reduce electromagnetic interference between each other, ensure the stability and normal operation of each circuit board, and avoid failures caused by signal interference. At the same time, if a problem or failure occurs on a certain circuit board, the part can be replaced or repaired in a targeted manner, without having to replace the entire circuit board as a whole, thereby reducing the cost and difficulty of repair. The first circuit board 21 and the second circuit board 22 are arranged in the cold air chamber 101. The air flow in the cold air chamber 101 can take away the heat generated by the control component 2 when it is working, thereby effectively reducing the temperature of the circuit board and ensuring its stable operation. At the same time, during the operation of the hair dryer, the temperature change in the cold air chamber 101 is relatively small, which makes the temperature fluctuations borne by the first circuit board 21 and the second circuit board 22 smaller. Smaller temperature fluctuations help reduce the damage of thermal stress to electronic components and solder joints on the circuit board assembly, thereby extending the service life of the circuit board.

[0043] like Figure 2 , Figure 3 and Figure 6 As shown, in addition to the features of the above-mentioned embodiment, the present embodiment further defines that: the control assembly 2 also includes a button assembly 23, the front shell 11 and the rear shell 12 are provided with a button fixing hole 102, the number of the button fixing holes 102 is multiple, the button assembly 23 is clamped in the multiple button fixing holes 102, and the button assembly 23 is arranged on the first circuit board 21 and the second circuit board 22. By arranging the button assembly 23 on the button fixing hole 102 provided on the front shell 11 and the rear shell 12, a precise installation position is provided for the button assembly 23, ensuring that each button can be accurately installed at a predetermined position, and at the same time, the button will not be loosened or displaced during use, thereby ensuring the stability and accuracy of the operation. By installing the button assembly 23 on the button fixing hole 102, the connection strength between the button and the handle housing assembly 1 can be increased, and the risk of the button being damaged or falling off can be reduced when the button is used. At the same time, the neatly arranged and fixed-position button assembly 23 can allow the user to find the required operation button more intuitively and easily, thereby improving the convenience and comfort of the hair dryer. The button assembly 23 is arranged to be movable on the first circuit board 21 and the second circuit board 22. The signal generated by the button assembly 23 can be directly transmitted through the lines on the circuit boards, reducing interference and attenuation of the signal during transmission, ensuring the stability and accuracy of the control signal, and enabling the function of the hair dryer to respond quickly and efficiently.

[0044] like Figure 2 and Figure 8 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the handle sleeve 4 is provided with a button operation hole 401, the number of the button operation holes 401 is multiple, and the multiple button operation holes 401 correspond to the control component 2 one by one and cooperate with each other. By providing multiple button operation holes 401 on the handle sleeve 4 and corresponding to the control component 2 one by one, the user can directly operate the button of the control component 2 through the button operation holes 401 on the handle sleeve 4, without having to find a specific position or worry about accidentally touching other components. This intuitive and convenient design allows the user to easily adjust various functions during the use of the hair dryer. At the same time, the handle sleeve 4 can provide physical protection for the control component 2 to a certain extent, reduce the direct impact of external factors on the control component 2, thereby ensuring the stability and accuracy of the operation of the control component 2 and extending the service life of the control component 2. The multiple button operation holes 401 are integrated with the overall design of the handle sleeve 4, making the appearance of the hair dryer look more neat and integrated, and will not appear messy due to abnormally protruding buttons.

[0045] Example 2

[0046] like Figures 1 to 8 As shown, this embodiment discloses a hair dryer, including the above-mentioned handle assembly; a main unit, which is arranged on the handle assembly, and the main unit and the handle assembly are connected by bolts and buckles.

[0047] The hair dryer disclosed in the second aspect of the present application has a main unit arranged on a handle assembly and the main unit and the handle assembly are connected by bolts and buckles to form an integral structure. The bolts provide a strong and reliable fixing force to ensure that the main unit will not loosen or separate from the handle assembly during use. The buckle can quickly achieve preliminary positioning and connection. The combination of the two makes the connection more stable, allowing the hair dryer to withstand a certain degree of external force impact and vibration, thereby extending its service life. In combination with the cold air chamber 101 provided in the handle assembly, it can not only dissipate the heat generated by the handle part to make the user more comfortable to hold, but also reduce the temperature of the electronic components inside the handle assembly during operation, thereby extending its service life. Combined with the above-mentioned multiple advantages, the hair dryer meets the actual needs of users and has certain market competitiveness.
