[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0037] Please refer to the following: Figures 1 to 8 The handle wiring structure 100 provided in this application embodiment will now be described. The handle wiring structure 100 includes: a handle housing 10, a front fixing bracket 20, and a rear fixing bracket 30.
[0038] The handle housing 10 is provided with a mounting cavity 13 for installing the components required for the hair styling device 200; the front fixing bracket 20 and the rear fixing bracket 30 are both installed in the mounting cavity 13, and the front fixing bracket 20 and the rear fixing bracket 30 are assembled together; the front fixing bracket 20 and / or the rear fixing bracket 30 are provided with notches, which allow internal cables to pass through and be routed outward.
[0039] Understandably, when the components installed on the front mounting bracket 20 and the rear mounting bracket 30 need to be wired, the cables are passed out through the notch and arranged on the outer surface of the front mounting bracket 20 and the rear mounting bracket 30.
[0040] In some embodiments of this application, the notch includes a first notch 21 on the rear surface of the front mounting bracket 20 and a second notch 31 on the front surface of the rear mounting bracket 30. The first notch 21 can penetrate the inner and outer surfaces of the front mounting bracket 20, and the second notch 31 can penetrate the inner and outer surfaces of the rear mounting bracket 30. After the front mounting bracket 20 and the rear mounting bracket 30 are installed together, the first notch 21 and the second notch 31 can form a cable passage hole for the cable to pass through from the inside to the outside.
[0041] Specifically, by setting up a front fixing bracket 20 and a rear fixing bracket 30, and forming a cable passage hole through the first notch 21 of the front fixing bracket 20 and the second notch 31 of the rear fixing bracket 30, cables can be passed through the cable passage hole and placed on the outside of the front fixing bracket 20 and the rear fixing bracket 30 during the assembly process. This prevents cables from being stuck by components during assembly, thereby reducing the difficulty of assembling each component. At the same time, placing the cables through the cable passage hole on the outside of the front fixing bracket 20 and the rear fixing bracket 30 prevents cables from entering the air duct, improving the airflow and air delivery efficiency of the air duct.
[0042] It is understandable that when only the notch is provided in the front mounting bracket 20, the front mounting bracket 20 and the rear mounting bracket 30, after assembly, can enclose the cable passage hole of the front mounting bracket 20; when only the notch is provided in the rear mounting bracket 30, the front mounting bracket 20 and the rear mounting bracket 30 can enclose the cable passage hole of the rear mounting bracket 30; in addition, the notch can also be used to form a single cable passage hole penetrating the inner and outer surfaces of the front mounting bracket 20, and the notch can also be used to form a single cable passage hole penetrating the inner and outer surfaces of the rear mounting bracket 30; similarly, the cables of the front mounting bracket 20 and the rear mounting bracket 30 can be arranged outward through the cable passage hole.
[0043] In some embodiments of this application, the top of the front mounting bracket 20 is provided with a first mounting recess 22, and the top of the rear mounting bracket 30 is provided with a second mounting recess 32. The first mounting recess 22 and the second mounting recess 32 are open on opposite sides and enclose the mounting position for mounting the first circuit board 40.
[0044] Preferably, the first circuit board 40 is a control circuit board, and a control button 42 is integrated on the top of the first circuit board 40. The control button 42 can be exposed on the surface of the handle housing 10 through the through hole of the handle housing 10, so that when holding the handle housing 10, the working status of each component can be controlled by touching or pressing the control button 42.
[0045] Specifically, the front end of the first mounting recess 22 is provided with a first mounting post 23, the rear end of the second mounting recess 32 is provided with a second mounting post 33, and the first circuit board 40 is provided with a first mounting hole 41 adapted to accommodate the insertion of the first mounting post 23 and the second mounting post 33. The stability of the first circuit board 40 assembly can be improved by the cooperation of the first mounting post 23 and the first mounting hole 41.
[0046] In some other embodiments of this application, the second notch 31 and the first notch 21 are stacked inside and outside to form a wire passage hole. The rear fixing bracket 30 is provided with a wiring channel 34 on the rear side of the second notch 31. The wire passage hole is located on the left or right side between the first mounting recess 22 and the second mounting recess 32, or it can be located on the left and right sides between the first mounting recess 22 and the second mounting recess 32.
[0047] Specifically, the wiring channel 34 is provided with a guide step 35 and a wire-clamping hook 36. The second notch 31, the guide step 35, and the wire-clamping hook 36 are arranged at intervals from front to back. During wiring operations, the cable passes out through the cable hole, then extends along the guide step 35 towards the rear end of the wiring channel 34, allowing the cable to be inserted into the wire-clamping hook 36 and continue to extend rearward to connect with the corresponding control unit 50, circuit board, or power supply.
[0048] More specifically, two cable catches 36 can be provided, corresponding to the upper and lower sides of the wiring channel 34, with the free ends of the two cable catches 36 spaced apart. This structure ensures that the cable catches 36 can reliably and stably restrict the cable position. Due to the front-to-back spacing between the guide step 35 and the second notch 31, when the cable passes through the through hole and extends backward, a gap is formed between the through hole and the guide step 35 to prevent the cable from breaking.
[0049] Furthermore, the outer surface of the rear fixing bracket 30 is provided with an annular groove 37. Wrapping adhesive tape in the annular groove 37 can further wrap and fix the cable located in the wiring channel 34, thereby further improving the reliability of cable fixing.
[0050] In some embodiments of this application, the front mounting bracket 20 has a first air duct 201 extending through its front and rear surfaces, and a heating element 202 is installed within the first air duct 201. The rear mounting bracket 30 has a second air duct 301 extending through its front and rear surfaces, and the second air duct 301 is electrically connected to the first air duct 201. A motor assembly 302 is installed in the second air duct 301. A control unit 50 is installed at the rear of the rear mounting bracket 30. The heating element 202, the motor assembly 302, and the first circuit board 40 are signal-connected or electrically connected to the control unit 50. The user can control the operating status of the heating element 202 and the motor assembly 302 via the control unit 50 by touching the control button 42 on the first circuit board 40.
[0051] It should be noted that after the upper shell 11 and the lower shell 12 are assembled, an air inlet is provided at the rear end of the upper shell 11 and the lower shell 12. The air inlet allows outside air to flow into the first air duct 201 and the second air duct 301.
[0052] Specifically, the front fixing bracket 20 has a first fastening window 203 on the rear side of its outer surface, and the rear fixing bracket 30 has a first fastening protrusion 303 on the front side of its outer surface. The first fastening protrusion 303 can be fastened into the first fastening window 203. The handle housing 10 includes an upper housing 11 and a lower housing 12. Both the upper housing 11 and the lower housing 12 are provided with a second fastening protrusion 15. The front fixing bracket 20 and / or the rear fixing bracket 30 are provided with a second fastening groove 24 for the second fastening protrusion 15 to be fastened into. After the upper housing 11 and the lower housing 12 are fastened together, the outer shell 14 is covered on the outer surface of the upper housing 11 and the lower housing 12 to form the handle wiring structure 100 as a whole.
[0053] During assembly, firstly, the heating element 202 is installed in the first air duct 201, and the cables connected to the heating element 202 are guided and arranged in the first notch 21; then, the motor assembly 302 is installed in the second air duct 301, and the cables of the motor assembly 302 are guided and arranged in the second notch 31; then, the front heating element 202 and the rear heating element 202 are fastened together with the first fastening protrusion 303 through the first fastening window 203, and the aforementioned cables are extended rearward through the wiring channel 34; furthermore, the first circuit board 40 is correspondingly installed in the first mounting recess 22 and the second mounting recess 32, and tape is wrapped around the annular groove 37 to secure the first circuit board. The cables in the board 40 and the wiring channel 34 are wound and fixed; then, the lower housing 12 is fixed by the second fastening protrusion 15 and the second fastening groove to install the front fixing bracket 20 and the rear fixing bracket 30 on the lower housing 12. At this time, the control unit 50 is also installed on the lower housing 12 and placed behind the rear fixing bracket 30; then, the cable in the wiring channel 34 is guided backward and connected to the control unit 50; finally, the upper housing 11 is fixed by the second fastening protrusion 15 and the second fastening groove, and the outer shell 14 is covered on the outer surface of the upper housing 11 and the lower housing 12 to complete the assembly of a handle wiring structure 100.
[0054] As can be seen, after the various components are assembled by the front mounting bracket 20 and the rear mounting bracket 30, the cable can be passed through the cable hole and extended to the rear through the wiring channel 34 to connect with the control unit 50. Because the cable is effectively organized, it can prevent the cable from getting stuck during the assembly of each component, thereby reducing the difficulty of assembling each component.
[0055] It should be noted that the cable passage holes are located on the left and right sides of the first and second mounting recesses. The corresponding wiring channels, guide steps, and cable hooks are set according to the position of the cable passage holes so that the cables can be extended backward from different sides.
[0056] In some other embodiments of this application, a hair styling device 200 is also included, which includes an accessory 2001 and a handle wiring structure 100. The accessory 2001 is any one of a hair dryer, a curling iron, or a hair comb. The accessory 2001 can be integrally formed with the handle wiring structure 100 or detachably assembled together.
[0057] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
