Technical Field

[0001] This utility model relates to a handheld fan, specifically a handheld fan with a flexible decorative panel. Background Technology

[0002] Handheld fans, as portable personal cooling devices, are widely used in daily life, outdoor activities, and travel. Existing handheld fans typically consist of two parts: a fan head and a handle. The fan head houses the fan blades, motor, and air guide, generating airflow. The handle serves as the grip and power storage area, integrating the motherboard, battery, control switch, and charging port. Users control the fan speed and on / off status via buttons to meet different usage needs.

[0003] However, the existing handheld fans have a relatively simple appearance, especially in the handle area, where hard plastic shells are often used as the outer surface, resulting in a stiff and uncomfortable grip. Furthermore, due to the limited internal space of the handle, integrating a display screen or function indicator module not only increases assembly difficulty but also easily compromises the overall aesthetics, reducing the product's sense of unity and style. In addition, traditional decorative panels are mostly fixed structures, making it difficult to quickly remove and replace them when wear and tear occurs or when the user wants to change the appearance, thus limiting the product's flexibility.

[0004] To address the aforementioned issues, some improved handheld fans have attempted to incorporate decorative covers or encased shells on the handle. However, these solutions typically still use rigid materials or adhesive mounting, failing to effectively balance a soft touch with structural reliability. Furthermore, integrating electronic components such as displays or indicator lights into the decorative layer can lead to stress concentration or assembly deviations due to the curved surface of the handle, making it difficult to achieve a good fit and stable electrical connections.

[0023] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0024] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0025] like Figure 1 and Figure 2 As shown, this utility model proposes a handheld fan with a flexible decorative panel 1. The overall structure includes a fan head 8, a handle 6, and a flexible decorative panel 1 installed on the outer surface of the handle 6. The structural design of this device not only considers heat dissipation performance and portability, but also takes into account aesthetics, grip comfort, and the integration of display functions, thereby achieving comprehensive optimization in terms of functionality and user experience.

[0026] The specific implementation method is as follows:

[0027] The fan head 8 is mounted on the top of the handle 6 and serves as the air outlet component of the entire handheld fan. The fan head 8 contains conventional structures such as a drive motor, fan blades, air guide cover, and motor mounting bracket. The motor is driven by power signals output from the main board to achieve different wind speed settings.

[0028] The handle 6 is used to support the fan head 8 and to house the power supply, circuit board and control components. It is the functional center and main body for holding the whole machine.

[0029] The handle 6 is ergonomically designed to form an arc or oval grip area, and has a recessed mounting cavity on its surface for embedding the flexible decorative panel 1, so that the overall appearance remains flat and has a high degree of fit.

[0030] The flexible decorative panel 1 is a detachable structure, mainly composed of three parts: a decorative layer, a flexible circuit board, and a flexible protective layer. The decorative layer is the outermost surface layer, made of flexible fabric material, and the surface of the fabric layer is printed with decorative textures, which can be replaced in various ways according to different design styles or usage scenarios.

[0031] This decorative layer not only serves an aesthetic purpose but also effectively improves the user's grip, making the handle 6 less slippery during prolonged use and reducing hand fatigue. A flexible circuit board is embedded within the decorative layer, with conductive lines and electronic components evenly distributed on its surface. A digital display screen is mounted on its surface. This screen can display information such as fan speed, battery status, temperature indicators, or running time, thereby enhancing the product's intelligent interactive experience.

[0032] The flexible circuit board is electrically connected to the mainboard inside the handle 6 via a flexible flat cable. The mainboard integrates a power management module, a drive circuit module, and a signal processing unit.

[0033] The power module provides a stable power output to the flexible circuit board and digital display screen. The drive module adjusts the motor speed according to the user's button commands. The signal processing unit is used to transmit the operating status data to the display area on the flexible circuit board so as to display the current device status in real time.

[0034] Because of the use of flexible flat cable connection, the entire connection structure has good bending performance and stress resistance, and can maintain a stable electrical connection during the disassembly or bending of the flexible decorative panel 1, avoiding the problems of broken wires or poor contact that occur in traditional rigid board connections.

[0035] The flexible circuit board is wrapped with a flexible protective layer to protect the internal electronic components and conductive lines. The flexible protective layer is made of elastic transparent resin or silicone material, which can prevent damage from external pressure, sweat corrosion, and friction damage during daily use.

[0036] Both sides of the protective layer are equipped with buckle structures 3, corresponding to the slots 7 on the handle 6. During assembly, the user only needs to insert the buckles 3 on both sides of the flexible decorative panel 1 into the slots 7 along the edge of the assembly cavity of the handle 6, and achieve a stable fixation through the mechanical cooperation between the buckles 3 and the slots 7.

[0037] When the decorative panel needs to be replaced, it can be easily removed by simply prying off clip 3, without the need for tools. The structure is simple and the operation is convenient. This disassembly and assembly method not only improves maintenance and replacement efficiency, but also allows users to change the decorative panel to different colors or textures according to their personal preferences, enhancing the product's customizability and appearance diversity.

[0038] The handle 6 is equipped with multiple control buttons 5, which are connected to the main board via conductive membrane switches or micro switches. Users can use the control buttons 5 to adjust fan speed, turn the device on / off, and check battery level. A button clearance groove 2 is provided on the flexible decorative panel 1 corresponding to the positions of the control buttons 5. This groove is pre-formed during the molding of the flexible decorative panel 1, ensuring that the outer end face of the control button 5 is within the groove, thus guaranteeing that the normal operating stroke and feel of the button are not affected after assembly. The edges of the clearance groove are rounded or chamfered to prevent scratching or tearing of the panel during use, ensuring the product's durability and safety.

[0039] Furthermore, the flexible decorative panel 1 is installed in the mounting cavity formed by the recess on the outer surface of the handle 6. The depth of the mounting cavity is slightly less than the total thickness of the decorative panel, so that the surface of the flexible decorative panel 1 after assembly is basically flush with the outer surface of the handle 6. This ensures a smooth and flat overall appearance and creates a natural visual transition, enhancing the aesthetics of the entire device. At the same time, this embedded assembly method also enhances the stability of the panel, preventing loosening or warping caused by external forces or long-term use.

[0040] In practice, the decorative layer can be made of different materials depending on the product positioning, such as fabric, TPU, silicone, or leather composites. When using a fabric layer, various patterns, logos, or textures can be printed on its surface, satisfying decorative needs while providing a soft touch and significantly improving the grip experience. The flexible circuit board can be manufactured using FPC (Flexible Printed Circuit Board) technology to ensure good electrical reliability during repeated bending, installation, and disassembly.

[0041] The fan head is also equipped with an ice pack head 100. Specifically, a semiconductor cooling chip can be installed inside the fan head, with the cold side of the semiconductor cooling chip facing outward and the hot side facing inward. Therefore, heat dissipation fins can be installed on the sides and back of the ice pack head to dissipate heat to the outside. In summer when the temperature is high, the ice pack head can be used for cooling.

[0042] This handheld fan not only integrates display and control functions but also features a flexible, detachable, and customizable structure. The flexible decorative panel 1 enhances the overall aesthetics and grip comfort, while its modular design facilitates user replacement and maintenance. Its integrated flexible circuit board structure allows for flexible placement of the display function on the decorative panel without occupying the limited internal space of the handle 6, effectively optimizing the internal structural layout and enhancing the product's integrated design.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
