[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that if directional indications are involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0031] refer to Figure 1-9 The figure discloses a hair dryer 100, which includes a body 1 and a handle 2 connected to the body 1. The axis of the body 1 and the axis of the handle 2 are basically perpendicular. Of course, the axes of the two can also be at other angles, which is not limited in detail here.

[0032] Hair dryer 100 includes a first air duct 11 and a second air duct 21. First air duct 11 includes a third air duct 12 defined by handle 2 and a fourth air duct 13 defined by body 1. Airflow in fourth air duct 13 extends substantially along the axis of handle 2. Second air duct 21 is defined by body 1. In one embodiment, the airflow in third air duct 12 is substantially parallel to the airflow in second air duct 21. In other embodiments, the airflow in third air duct 12 and the airflow in second air duct 21 may be at an angle.

[0033] The handle 2 is provided with a first air inlet 14 in fluid communication with the third air duct 12. The first air inlet 14 is generally provided at the lower end of the handle 2. The body 1 is defined by a first air outlet 15 in fluid communication with the fourth air duct 13. The body 1 is further defined by a second air inlet 22 and a second air outlet 23 in fluid communication with the second air duct 21. The third air duct 12 is provided with a first fan 3 for generating an airflow. The second air duct 21 is provided with a second fan 4 for generating an airflow. The second air duct 21 is provided outside the third air duct 12. With the above structure, one fan is provided in the handle 2 and the other fan is provided in the head. This not only effectively utilizes the space of the hair dryer 100, but also effectively reduces the noise generated by the two fans. If the two fans are placed close together, the vibrations generated by the two fans will be superimposed, generating relatively loud noise.

[0034] refer to Figure 3 In the embodiment shown in the figure, the second air duct 21 is arranged directly above the third air duct 12. Placing the two fans as far away as possible can effectively avoid interference between the two fans.

[0035] To achieve conventional control of the hair dryer 100, a control board 24 is also included. This board is a PCB commonly used by those skilled in the art. The control technology used in the hair dryer 100 is conventional and will not be described in detail here. To improve space utilization and rapidly dissipate heat from the control board 24, the control board 24 is positioned at the intersection of the third air duct 12 and the fourth air duct 13. This allows the high-speed airflow within the first air duct 11 to dissipate the substantial heat generated by the control board 24, thereby cooling it.

[0036] In order to improve the user experience, the hair dryer 100 also includes an ion generator 25, which can be one or more of a water ion generator 25, a plasma generator 25, a negative ion generator 25, and a metal ion generator 25. The ion generator 25 is a common component and will not be described in detail here. The ion generator 25 is arranged in the second air duct 21. By arranging the ion generator 25 in the second air duct 21, the space of the entire hair dryer 100 can be effectively utilized. The ion generator 25 includes a control element and an emission needle, wherein the control element and the emission needle are both arranged in the second air duct 21. In order to facilitate the wiring harness to be connected from the fourth air duct 13 to the second air duct 21. A wire plug 16 is provided between the fourth air duct 13 and the second air duct 21, and the wire plug 16 is provided with a wire hole, which connects the fourth air duct 13 and the second air duct 21. The wire plug 16 can effectively prevent the wind in the second air duct 21 and the fourth air duct 13 from flowing cross-currently, thereby avoiding noise. Reference Figure 3 The second air inlet 22 further includes an air inlet grille 19 arranged on the body 1 , and the air inlet area of ​​the air inlet grille 19 is larger than the air inlet area of ​​the second air inlet 22 .

[0037] refer to Figure 3-9 In one specific embodiment, the body 1 includes an outer shell 31 and an inner shell 32 disposed within the outer shell 31. The inner shell 32 defines the second air duct 21 and the fourth air duct 13. A wire plug 16 is disposed between the second and fourth air ducts 21 and 13. The wire plug 16 is provided with a first through-hole 17 and a second through-hole 18. The first through-hole 17 connects the second and fourth air ducts 21 and 13, while the second through-hole 18 connects the fourth air duct 13 with the space outside the inner shell 32. A first wire harness 33 between the control board 24 and the second blower 4 passes through the first through-hole 17. The handle 2 includes a first housing and a second housing disposed outside the first housing. The first housing defines the third air duct 12. A controller 28 is defined within the handle 2 and disposed between the first and second housings. The controller 28 is electrically connected to the control board 24 via a second wire harness 34. The second wire harness 34 enters the fourth air duct 13 from the space defined by the inner shell 32 and the outer shell through the second through-hole 18.

[0038] To ensure that the airflow in each air duct is heated, a first heater 26 is installed in the fourth air duct 13, and a second heater 27 is installed in the second air duct 21. The second air inlet 22 also includes an air inlet grille 19 installed on the body 1. The air inlet area of ​​the air inlet grille 19 is larger than the air inlet area of ​​the second air inlet 22.

[0039] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
