[0001] The utility model relates to the field of hair dryer electrical appliances, in particular to a hair dryer with uniform air flow through the air duct. Background Art
[0002] Existing hair dryer designs usually have a hot air output function. An air duct is provided inside the hair dryer to output and input airflow from the outside. After passing through the blower, the airflow is output from a specific position in the air duct. However, the air duct usually has a certain inner diameter. Generally, the current heating component is installed relatively close to one end of the air outlet, and the air supply duct of the blower is perpendicular to the heating wire. However, the present invention provides a vertical air outlet method, and the air at different cross-sectional positions cannot blow evenly through the internal heating component, so that the specific position of the air duct can output hot air with a relatively uniform temperature everywhere.
[0003] In view of this technical defect, it is necessary to propose a new technical solution. Utility Model Content

[0009] Furthermore, one end side wall of the fan body is covered with a first filter and an outer shell from inside to outside, the outer shell is circumferentially provided with a plurality of the air inlets, and the other end side wall is provided with a plurality of the first air outlets in parallel strips.
[0010] Furthermore, the ventilation duct between the air inlet and the fan is provided with a second filter screen, and the second filter screen and the windward surface of the ventilation duct are perpendicular to each other.

The heating component is arranged corresponding to the first air outlet, and one end of the heating component is connected to the first air branch, the second air branch and the third air branch. The airflows from the three air branches pass through the heating components inside the ventilation duct evenly, and are heated more evenly. Finally, more evenly heated air is output from the first air outlet, so that the user can receive hot air with more evenly heated air for purposes such as blowing their hair. In addition, the heating component is arranged in an adjacent position between the first air outlet and the air guide plate. The heating component is arranged close to the first air outlet with a large area.

[0025] Reference Figures 1 to 5 As shown, in some embodiments, the utility model discloses a hair dryer with uniform air flow through the air duct, which includes:
[0026] Reference Figures 1 to 2The fan body 100 shown in the figure has a ventilation duct 110 provided inside the fan body 100. The outer contour of the fan body 100 in the figure is a rod, and may also be S-shaped, L-shaped or C-shaped. An air inlet 120 is provided at one end of the fan body 100, and a first air outlet 130 is provided at the other end. The ventilation duct 110 is connected to the air inlet 120 and the first air outlet 130 respectively. A fan 200, an air guide plate 300 and a heating component 400 are sequentially provided on the ventilation duct 110 between the air inlet 120 and the first air outlet 130. The ventilation duct 110 of the hair dryer draws in external air from the air inlet 120 at one end, accelerates the airflow through the front-end fan 200 of the ventilation duct 110, and then passes through the ventilation duct 110 of the remaining path, blows to the air guide plate 300, and is divided into the following three wind branches. Refer to Figure 2 、 3 as well as Figure 5 As shown, the wind guide plate 300 is parallel to the windward surface of the ventilation duct 110, and the wind guide plate 300 is divided into two side ventilation ducts 110, which are the first air branch 310, the second air branch 320 and the third air branch 330 of the top side ventilation duct 110. The airflow is slightly decelerated after passing through the three air branches. The heating component 400 is arranged corresponding to the first air outlet 130, wherein one end of the heating component 400 is arranged adjacent to the first air branch 310, the second air branch 320 and the third air branch 330. The airflow of the three air branches passes evenly through the heating component 400 inside the ventilation duct and is heated more evenly. Finally, more evenly heated air is output from the first air outlet 130, and the user can receive hot air with more evenly heated air for purposes such as blowing hair.
[0027] Continue to refer to Figures 2 to 5 As shown, a control circuit board 500 is installed on the ventilation duct 110 between the fan and the air guide plate 300. The control circuit board 500 is perpendicular to the windward surface of the ventilation duct 110. The control circuit board 500 divides the ventilation duct 110 into two sides: a fourth air flow branch 510 and a fifth air flow branch 520. These two air flow branches can not only dissipate heat for the heat-generating components on the control circuit board 500, but also provide a pre-flow airflow ahead of the air guide plate, thereby ensuring uniform airflow across the ventilation duct with a certain inner diameter. The first air flow branch 310 and the second air flow branch 320 are respectively connected to the fourth air flow branch 510, and the fifth air flow branch 520 is connected to the third air flow branch 330. The airflow from the two pre-flow branches then passes through the three air flow branches of the air guide plate, ensuring uniform airflow across the ventilation duct 110. The airflow passing through the heat-generating component 400 is heated more evenly.
[0028] Reference Figure 3As shown, the cross-sectional shape of the air guide plate 300 is trapezoidal, and the air guide plate 300 is integrally connected to the inner wall of the ventilation duct 110. The air guide plate of this shape has a good air guiding effect.
[0029] Continue to refer to Figure 2 Combine Figure 4 As shown, the heating component 400 includes a cross bracket 410 arranged on the ventilation duct 110 and a heating wire arranged on the cross bracket 410. The cross bracket 410 and the windward surface of the ventilation duct 110 are perpendicular to each other. The outer periphery of the cross bracket can be wound with a uniform heating wire, so that the uniform airflow is evenly heated in the uniform multiple heating wires and then output through the first air outlet 130.
[0030] Reference Figure 2 Combine Figure 4 As shown, one end side wall of the fan body 100 is covered with a first filter 140 and an outer shell 150 from the inside to the outside. The outer shell 150 is circumferentially provided with a plurality of the air inlets 120, and the other end side wall is provided with a plurality of the first air outlets 130 in parallel strips. The outer shell 150 is provided with a plurality of first air outlets 130 as a side wall, which can increase the input airflow. The ventilation duct 110 between the air inlet 120 and the fan is provided with a second filter 600, and the second filter 600 is perpendicular to the windward surface of the ventilation duct 110. The first filter 140 and the second filter 600 can filter the external dust twice, making the subsequent output blowing airflow purer.
[0031] Continue to refer to Figure 4 As shown, the blower body 100 is detachably connected to a plurality of nozzle assemblies 700 corresponding to the first air outlet 130. The plurality of nozzle assemblies 700 include a nozzle piece 710, which is provided with a second air outlet 711. The second air outlet 711 is interconnected with the first air outlet 130. The user can replace the nozzle with a different shape according to their needs. The hair dryer can be used for personal use or for drying pet hair.
