[0024] See Figures 1 to 6This embodiment provides a hair dryer, including a hair dryer body 1, a hair dryer handle 2 at the bottom of the hair dryer body 1, and a motor bracket 3, a heating bracket 4, and an air outlet housing 5 arranged sequentially from back to front inside the hair dryer body 1. The motor bracket 3 is equipped with a motor 6 with a fan, the heating bracket 4 is equipped with a heating element, and the air outlet housing 5 is equipped with an air outlet. A lamp PCBA 7 and a back cover 8 are arranged sequentially behind the motor bracket 3. A power supply PCBA 201 is installed inside the hair dryer handle 2, and a hot air button 202 is provided on the side wall of the hair dryer handle 2. The hot air button 202 is connected and cooperates with the power supply PCBA 201. The power supply PCBA 201 is electrically connected to the motor 6, the heating element, and the lamp PCBA 7. The hot air button 202 is used to adjust the temperature generated by the heating element. The lamp PCBA 7 emits different colors of light according to the different temperatures generated by the heating element. The light emitted by the lamp PCBA 7 is displayed outward through the back cover 8. Function: (1) By setting up a hair dryer barrel, the bottom of the hair dryer barrel is provided with a hair dryer handle, and the inside of the hair dryer barrel is provided with a motor bracket, a heating bracket, and an air outlet housing arranged sequentially from back to front. The motor bracket is provided with a motor with a fan, the heating bracket is provided with a heating element, and the air outlet housing is provided with an air outlet. Thus, when the motor works, the motor will drive the fan to rotate, and the rotation of the fan will drive the airflow behind the hair dryer to flow from back to front. As the airflow flows forward, it will pass through the heating bracket and the air outlet housing in sequence. The heating element on the heating bracket can heat the airflow to form hot air, and the air outlet on the air outlet housing can allow the airflow to pass through the air outlet housing and blow outward. (2) A lamp PCBA and a back cover are arranged in sequence behind the motor bracket. A power PCBA is located inside the hair dryer handle. A hot air button is located on the side wall of the hair dryer handle. The hot air button is connected to the power PCBA. The power PCBA is electrically connected to the motor, the heating element, and the lamp PCBA. The hot air button is used to adjust the temperature generated by the heating element. The lamp PCBA emits different colors of light according to the different temperatures generated by the heating element. The light emitted by the lamp PCBA is displayed outward through the back cover. Thus, when the user uses the hot air button to adjust the temperature generated by the heating element, the heating element will generate the corresponding temperature after adjustment (such as 60℃, 80℃, 100℃, etc.). Then, the lamp PCBA emits different colors of light according to the different temperatures generated by the heating element (such as blue light at 60℃, yellow light at 80℃, red light at 100℃, etc.). Then, the light emitted by the lamp PCBA is displayed outward through the back cover. Finally, the back cover can display the corresponding light color according to the current internal temperature of the hair dryer. As can be seen from the analysis, the back cover of this utility model can display different bright colors according to the different internal temperatures of the hair dryer, so that users can intuitively understand the current internal temperature of the hair dryer and make it convenient to use.

[0025] Specifically, the hot air button 202 has three sequentially changing settings. The heating element heats up according to the three settings of the hot air button 202, generating three different temperatures in sequence. Function: Through the three settings of the hot air button 202, the temperature of the heating element can be adjusted to 60℃, 80℃, and 100℃.

[0026] Specifically, the three temperatures of the heating element increase sequentially, and the LED PCBA7 emits blue, yellow, and red light sequentially according to these three temperatures. Function: As the temperature of the heating element increases, the LED PCBA7 can generate blue, yellow, and red light respectively according to the three temperatures, and display the corresponding light colors outwards through the back cover.

[0027] Specifically, the side wall of the hair dryer handle 2 is also equipped with a cold air button 203, which is connected and cooperates with the power supply PCBA 201. The cold air button 203 has two settings. The heating element switches between cold and hot air states depending on the two settings of the cold air button 203. The LED PCBA 7 emits white light according to the cold air state of the heating element, and the heating element is used for heating when it is in the hot air state. Function: When the two settings are set by the cold air button 203, switching to one setting activates the heating element in the cold air state, the LED PCBA lights up white, and the back cover correspondingly displays a white light. Switching to the other setting restores the heating element to the hot air state before the cold air state, at which point the heating element begins to heat up.

[0028] Specifically, the side wall of the hair dryer handle 2 is also equipped with a speed control button 204, which is connected and cooperates with the power supply PCBA 201. The speed control button 204 has sequentially changing power off, first speed, and second speed. The motor 6 is in the power off state, first speed state, and second speed state according to the power off state, first speed state, and second speed state of the speed control button 204. Function: The speed control button 204 has three speeds, so the hair dryer can have power off, first speed, and second speed, and the motor 6 can have the power off state, first speed state, and second speed state respectively, so as to reasonably adjust the wind speed. When the speed control button 204 is in the power off state, other components are also in the power off state (such as the heating element, light PCBA, etc.). Preferably, the wind speed in the first speed state is 90,000 revolutions per minute, and the wind speed in the second speed state is 125,000 revolutions per minute.

[0029] Specifically, the hot air button 202 and cold air button 203 work in conjunction with the power supply PCBA 201, allowing for temperature switching. The speed control button 204 works in conjunction with the power supply PCBA 201, allowing for temperature switching. Functions: Pressing the hot air button 202 cycles through different temperatures, corresponding to a color displayed on the back cover (e.g., blue for 60℃, yellow for 80℃, and red for 100℃). Pressing the cold air button activates cold air, illuminating the back cover light in white. Pressing it again returns to the previous hot air setting, where hot air is emitted. The speed control buttons, from top to bottom, represent the second, first, and power-off settings.

[0030] Specifically, when the speed control button 204 is switched from the off position to the first speed setting, the motor 6 rotates in the forward direction, and the heating element generates hot air. Pressing the cool air button 203 switches the heating element to a cool air setting. When the speed control button 204 is switched from the first speed setting to the off position, pressing the cool air button 203 causes the motor 6 to rotate in the reverse direction. Function: After the hair dryer is switched off and then on again (e.g., when the speed control button 204 is in the first or second speed setting), the default temperature setting is the last hot air setting (i.e., hot air mode), for user convenience. After the hair dryer is switched off, pressing the cool air button (e.g., for 3 seconds) activates the cleaning mode. The motor reverses to clean the dustproof structure (e.g., the filter 9 mentioned below). The cleaning mode runs for (e.g., 10 seconds) and then automatically stops.

[0031] Specifically, a filter 9 is provided between the motor bracket 3 and the lamp PCBA7. The filter 9 is mounted on the rear end face of the motor bracket 3. There is a gap between the filter 9 and the lamp PCBA7 and the rear cover 8. The rear cover 8 covers the lamp PCBA7, and there is a gap between the rear cover 8 and the inner wall of the blower barrel 1. Function: Driven by the fan of the motor, the external airflow behind the blower passes through the edge of the rear cover and the filter 9 in sequence before entering the motor bracket 3, and flows from back to front. The filter can filter out some foreign objects.

[0032] Specifically, the heating bracket 4 includes a mica support frame 401 and several mica sheets 402. The mica sheets 402 are arranged on the outer circumference of the mica support frame 401. The heating element is a heating wire assembly, which is wound around the mica sheets 402. An NTC detection device 403 and a temperature control switch 404 are located on the outside of the mica support frame 401, between the mica sheets 402. Functions: The NTC detection device can detect the temperature, and the air outlet temperature should be maintained at the corresponding temperature setting. The temperature control switch 404 can be set to disconnect when the air outlet temperature reaches 110 degrees Celsius.

[0033] Specifically, the motor bracket 3 includes a lower motor cover 301 and an upper motor cover 302. The motor 6 is disposed between the lower motor cover 301 and the upper motor cover 302. The lower front end of the lower motor cover 301 is provided with a vent 303, which is connected to the interior of the hair dryer handle 2. Function: The vent 303 is provided to dissipate heat from the power supply PCBA.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
