[0026] Reference Figure 2 The blower body 100 is provided with a blower bracket 110 inside, which is used to store a high-speed blower. The blower bracket 110 divides the inside of the blower body 100 into an air supply duct 120 and a first air inlet duct 130. Figure 3 It can be seen that the rear half of the hair dryer body 100 is the first air inlet duct 130 , and the front half is the air supply duct 120 .

[0027] Continue to refer to Figure 3As shown, a motor mounting channel 111 is defined in the middle of the fan bracket 110. The bottom of the fan bracket 110 is connected to one end of a fixed bracket 140, the other end of which is connected to the outlet of the air supply duct 120. The top of the fan bracket 110 is connected to one end of an air inlet bracket 150, the other end of which is connected to the inlet of the first air inlet duct 130. As can be seen from the accompanying drawings, the ends of the fan bracket are respectively connected to the fixed bracket and the ends of the air inlet bracket 150, allowing the fan bracket to be fixedly connected to the hair dryer body through components at both ends.

[0028] Continue to refer to Figure 2 Combine Figure 3 As shown, a blower 200 is disposed within the motor mounting channel 111, with a soft rubber layer 210 disposed between the outer wall of the blower 200 and the inner wall of the motor mounting channel 111. Current blowers typically utilize a rotational speed of up to 100,000 rpm. Such blowers typically have a high-speed motor mounted in the middle, with an air supply channel surrounding the motor. Blades are mounted on the motor shaft, driving the motor to draw air in from the first air inlet channel. Air is then accelerated by the blades and delivered out of the air supply channel for hair drying.

[0029] The above-mentioned hair dryer motor bearing structure, the high-speed fan is installed in the motor mounting channel between the fan brackets, and a soft rubber layer is provided between the high-speed fan and the fan bracket, so that the vibration generated by the motor during high-speed rotation operation can be partially absorbed by the soft rubber layer, effectively reducing the vibration generated by the entire hair dryer; in addition, the two ends of the fan bracket are respectively connected to the two ends of the fixed bracket and the air inlet bracket, so that the fan bracket can be fixedly connected to the hair dryer body through components at both ends, so that the motor and the fan bracket that it directly contacts are not directly in contact with the hair dryer body at both ends, thereby increasing the stability of the fan body.

[0030] Continue to refer to Figure 3 Combine Figure 5 As shown, a gradually widening trumpet-shaped air duct 112 is formed at the bottom of the fan bracket 110.

The aforementioned hair dryer structure draws air into the blower through the air inlet bracket. The high-speed airflow from the blower is then output through the trumpet-shaped air duct and the air supply duct, carrying away the aromatherapy aroma within the aromatherapy box.

[0032] Reference Figures 2 to 5 As shown, an air inlet fence 151 is circumferentially provided on the side wall of the air inlet bracket 150, and a filter 400 is provided between the air inlet fence 151 and the air inlet of the fan 200. The filter effectively blocks dust and other pollutants in the incoming air. A limiting portion is provided on the top of the fan bracket 110, and the filter 400 is arranged in the limiting portion. The limiting portion can be a bracket structure, and the filter is confined in the bracket and stably fixed.

[0033] Continue to refer to Figure 3 As shown, a control circuit board 600 is installed in the first air inlet duct 130 between the outer wall of the fan bracket 110 and the inner wall of the hair dryer body 100. The air inlet bracket 150 is provided with an air outlet corresponding to the control circuit board 600. If the control circuit board has components that generate heat, cool air can be input through the air outlet of the air inlet bracket to dissipate heat from the control circuit board.
