[0002] Hair dryers are a common household appliance, frequently used in places like hair salons. Modern hair dryers offer various usage modes, leading to the development of hair dryers with integrated displays to show the current status. Some hair dryer displays are located on the handle or air intake. However, the handle's limited space results in less information being displayed and it's easily obstructed by hands. Placing the display on the air intake allows for a larger screen without obstruction, making it the optimal solution. However, displaying a large amount of information necessitates multiple or flexible transmission cables to transmit signals. Current installation structures often lack sufficient space for cable routing and can obstruct airflow. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Please refer to Figure 1-9 ;

[0032] This utility model aims to optimize the installation structure of the display screen in a hair dryer to avoid affecting the air intake effect. Specifically, it includes a hair dryer body 1 and a display screen assembly 2. The air intake end of the hair dryer body 1 is provided with a bracket 3. In this embodiment, the hair dryer body 1 should include the necessary components to realize the normal use function of the hair dryer, which will not be described in detail here. The connection relationship between the bracket 3 and the hair dryer body 1 is not limited here. It can be integrally formed or installed as an independent component at the air intake end of the hair dryer body 1. The side of the bracket 3 is provided with several air intake parts 34 at intervals. An inner filter screen 4 is fixedly provided on the inner side of the bracket 3 to cover the several air intake parts 34. Since there is no extra installation space on the side of the bracket 3, and in order to avoid affecting the air intake, the display screen assembly 2 is located at the outer end of the bracket 3 away from the hair dryer body 1. It should be noted that the bracket 3 can be formed with a fixed structure to fix the display screen assembly 2, fix the display screen assembly 2 with the help of external fasteners, or install the display screen assembly 2 on an external part, such as an external filter cover 61, so that it is placed at the outer end of the bracket 3, etc., which are not limited here.

[0033] A wiring space 51 is provided between the inner wall of the bracket 3 and the outer wall of the inner filter 4. The two ends of the wiring space 51 are connected to the outer end of the bracket 3 and the internal space of the hair dryer body 1. Since hair dryers now need to display a lot of information, such as wind speed, temperature, blowing type, hot or cold air, etc., they cannot be transmitted by a single wire bus. That is, multiple wires are needed to transmit the corresponding signals. If so many wires are wound together, a large enough space needs to be reserved to form a wiring channel, which will affect the appearance. If so many wires are separated, the structure will become complicated. Therefore, in this embodiment, a flat printed flexible circuit board 52 is used to gather all the information lines together and place them in the wiring space 51. The two ends of the flexible circuit board 52 extend out of the outer end of the bracket 3 and into the hair dryer body 1, respectively, and are connected to the display screen assembly 2 and the controller.

[0034] For further information regarding the displayed information, please refer to [link / reference]. Figures 7-9 The multi-segment line on the outer ring indicates the gear position (A), the number in the middle indicates the temperature (B), and there are also low-speed silent mode (C), medium-speed gentle wind mode (D), high-speed strong wind mode (E), and cool wind mode (F).

[0035] Since the flexible circuit board is as thin as paper, it does not take up much space. Therefore, the gap between the bracket 3 and the inner filter screen 4 can be used to form a wiring channel. The structural design is novel and simple, and it will not affect the appearance. In addition, since the side wall of the bracket 3 does not participate in the air intake, the external gas will only enter it from the air intake part, so it will not affect the air intake process.

[0036] This utility model further explains the molding method of the bracket 3, referring to... Figure 3To simplify the structure, it is preferable to use an integral molding method. However, it is also necessary to consider the installation of other components. Therefore, the bracket 3 can be made in half on the two shells 11 of the hair dryer body 1. When it is necessary to install parts, the two shells 11 in the hair dryer body 1 are separated. After the parts are assembled and the inner filter 4 is placed on one half of the bracket 3, the two shells 11 are installed together. At the same time, the two halves of the bracket 3 are combined to fix the inner filter 4. The half bracket 3 can be fixed by a buckle 36.

[0037] Furthermore, the bracket 3 includes a fixing part 31 located at the outer end, which supports the display screen assembly 2. The fixing part 31 is provided with several support parts 32 and a mounting part 33 spaced apart. Both the support parts 32 and the mounting part 33 are connected to the hair dryer body 1. The inner filter 4 is tightly attached to the inner wall of the support parts 32. Preferably, the support parts 32 are provided with three mounting parts 33 arranged in a 90° ring. The inner sides of all support parts 32 are arc-shaped to match the curvature of the inner filter 4, thus effectively fixing the inner filter 4 and preventing vibration and noise caused by excessive airflow during air intake. Of course, the bracket 3 and the outer shell of the hair dryer body 1 also clamp the two ends of the inner filter 4. Additionally, since the flexible circuit board 52 is very thin and light, it is prone to swaying during air intake. Therefore, the mounting part 33 has a recessed mounting position 35 on its inner side, forming a windproof cavity to house the flexible circuit board 52.

[0038] Additionally, refer to Figure 5 The mounting part 33 is wider than the support part 32 in order to accommodate the flexible circuit board 52. The support part 32, which is only connected, can be made narrower to free up more space to form the air intake part 34. Therefore, the width of the mounting part 33 is greater than the width of the support part 32. Specifically, the width of the support part 32 is a, and the width of the mounting part is b, where b is greater than a.

[0039] In this embodiment of the utility model, reference is made to Figure 6 The display assembly 2 is fixedly mounted on the fixing part 31. The fixing part 31 is provided with a slot 311 for fixing the display assembly 2. Since the bracket 3 is a half-and-half structure, the entrance of the slot 311 will be exposed when it is separated. The display assembly 2 includes a display screen and a circuit board. The circuit board is located behind the display screen. The edges of both extend laterally to form a protruding edge 21. The protruding edge 21 is inserted into the slot 311. After the two halves of the bracket 3 are combined, the protruding edge 21 is clamped, thereby fixing the display assembly 2.

[0040] Preferably, a limiting block 312 is provided on the inner side of the slot 311, and a limiting groove 22 is provided on the protruding edge 21 of the display assembly 2. During installation, the limiting groove 22 is engaged in the limiting block 312 to prevent the display assembly 2 from rotating and breaking the flexible circuit board 52.

[0041] In this utility model, reference is made to Figure 4 It also includes an outer filter cover 61, which is fitted on the outside of the bracket 3 and is detachably connected to the hair dryer body 1. On the side of the outer filter cover 61 away from the hair dryer body 1, there is a hole 62 corresponding to the display screen assembly 2. The display screen assembly 2 protrudes from the hole 62, so that the display screen assembly 2 can be fully displayed and is more aesthetically pleasing. A protective ring 63 is installed on the outside of the hole 62. The protective ring 63 can cover the concave and convex parts of the outer filter cover near the display screen assembly 2 and is closer to the outer edge of the display screen assembly 2, which is more aesthetically pleasing and also provides protection. Preferably, the protective ring 63 protrudes slightly from the surface of the display screen assembly 2.

[0042] In addition, a number of positioning grooves 64 are provided at intervals on the outer periphery of the hole 62. The positioning grooves 64 are provided with mounting holes 65. The inner side of the protective ring 63 is provided with a number of positioning ribs 66 that cooperate with the positioning grooves 64. The positioning ribs 66 are provided with mounting posts 67 that are interference fit with the mounting holes 65, so as to realize the installation of the protective ring 63 and the outer filter cover 61. In addition, the mounting ribs also serve as reinforcing ribs.

[0043] Furthermore, the display assembly 2 is clamped in the slots 311 of the two brackets 32 and protrudes from the hole 65 of the outer filter cover 61. A protective ring 63 is also installed on the outside of the hole 65. The whole assembly is easy to disassemble and assemble, has a strong structure, and provides good protection.

[0044] Furthermore, the outer sides of several of the support portions 32 and one mounting portion 33 are close to the inner side of the outer filter cover 61. Since the outer filter cover 61 is relatively thin, this structure allows the support portions 32 and mounting portions 33 to support the outer filter cover and improve its impact resistance.

[0045] Additionally, refer to Figure 2 The inner side of the outer filter cover 61 is provided with a locking block 68, and the locking block 68 is provided with a locking position 69. The hair dryer body 1 is provided with a locking groove 12 near the air inlet end. The locking groove 12 is provided with a flange 13 that cooperates with the locking position 69, and an opening 14 is provided on the side for the locking block 68 to enter and exit, so as to realize a snap-fit ​​detachable structure, which is convenient for disassembly and cleaning.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
