[0028] The utility model will be further explained in detail in connection with the embodiment.

[0029] A high -speed brushless motor blow -out tube of stepless speed regulation, such as Figures 1-4 , including blow -out tube body, be equipped with processing board in blow -out tube body, processing board and blow -out tube body electricity is connected, be provided with stepless speed regulation module for adjusting the wind speed on processing board, stepless speed regulation module is provided with speed regulation pivot 1, speed regulation pivot 1 longitudinal setting, blow -out tube body on corresponding speed regulation pivot 1 place set up the longitudinal installation groove one 2, speed regulation pivot 1 exposes installation groove one 2 outside. Processing board selects 51 singlechip or STM series processor, stepless speed regulation module can select AOYI Austria DTS-25A-24V single -phase solid -state voltage regulator, or PWM pulse width stepless speed regulation module 12V / 24V / 36V's motor controller.

[0030] Still be provided with switch on processing board, switch is provided with press key 3, blow -out tube body on corresponding press key 3 place set up installation groove two 4, press key 3 exposes installation groove two 4 outside.

[0031] Speed regulation pivot 1 is located above press key 3, also can be below.

[0032] Still include display screen 5, be provided with signal output end on processing board, display screen 5 and signal output end electricity is connected, blow -out tube body on corresponding display screen 5 place set up installation groove three 6, display screen 5 exposes installation groove three 6 outside.

[0033] The processing board is also provided with a temperature sensor, which is electrically connected with the processing board, acquires the blowing temperature and transmits it to the processing board, and the processing board presents the temperature data on the display screen.

[0034] In addition, the hair dryer body also includes a power supply, a motor and a heating wire, which are all connected with the processing board. Figure 4

[0035] In terms of structure, Figures 1-3 the hair dryer body includes a base 7, a handle 8 and a blowing head 9 arranged in sequence from bottom to top, the widths of the base 7 and the blowing head 9 are greater than that of the handle 8; a mounting groove one 2 and a mounting groove two 4 are arranged on the handle 8, a mounting groove three 6 is arranged on the blowing head 9, and the temperature sensor is located at the blowing port of the blowing head 9.

[0036] In order to facilitate placement and avoid fatigue caused by long-term hand holding, the base 7 has a structure of being narrow at the top and wide at the bottom, and is provided with reinforcing ribs to not only prevent slipping but also increase counterweight, so that the placement is more stable. The width of the blowing head 9 is 1.2 to 1.8 times, preferably 1.5 times, of the width of the base 7, so that the widths of the blowing head 9 and the base 7 are similar, the design ratio in terms of width is more coordinated, and the base 7 is also thicker and heavier, avoiding the phenomenon that the blowing head 9 is too long in the traditional design to cause the gravity center of the hair dryer body to be unstable and unable to be normally placed vertically. Here, the width is taken as an example, which is the length value from left to right. Figure 1

[0037] In Figure 3 , the outer shell of the handle 8 is provided with an extension at the low end, which is integrally formed with the outer shell of the handle 8, and is inserted into the base 7, so that the installation is more firm and not easy to separate.

[0038] The use method of the hair dryer is as follows: a user holds the handle 8, presses the pressing key 3, and the hair dryer body starts to work, which is in the heating mode by default, and the hot air or cold air mode can also be selected through the display screen 5. If it is the hot air mode, the heating wire will be heated after the circuit board receives the heating signal; if it is the cold air mode, the heating wire does not work. Then the stepless speed regulation module is controlled by rotating the speed regulation shaft 1, the wind volume is + when the speed regulation shaft 1 is rotated upwards, and the wind volume is - when the speed regulation shaft 1 is rotated downwards, the circuit board receives the adjustment signal of the stepless speed regulation module, controls the rotating speed of the motor to adjust the rotating speed of the motor, so as to adjust the wind volume of the hair dryer body. The display screen 5 displays the wind volume value and the current hot air or cold air mode in real time, and the speed regulation shaft 1 is rotated until the demand is met in combination with the user's demand. When the user does not want to hold the handle 8, the base 7 can be placed on a plane.

[0039] ​​In addition, the base 7 of the blow dryer body can be removed or reduced in width to be consistent with the handle 8, and only the holding function is used, such as Figures 5-7 The shell of the blow dryer body is directly buckled on the blow dryer body.
