[0039] One embodiment of this utility model proposes a handheld device, see reference. Figures 1 to 7 ,include:

[0040] The fan body 1 has a fastening groove 11 at the bottom;

[0041] Handle 2 is detachably installed on fan body 1. A locking mechanism 6 is provided on handle 2. The locking mechanism 6 includes a button switch 61, a locking part 62 and an elastic element 63. The button switch 61 is fixedly connected to the locking part 62 and the elastic element 63 is located between the locking part 62 and handle 2.

[0042] The locking part 62 and the fastening groove 11 have a locked state and an unlocked state; the push-button switch 61 is used by the user to press to drive the locking part 62 downward so that the locking part 62 is unlocked from the fastening groove 11; the elastic member 63 is used to drive the locking part 62 upward so that the locking part 62 is locked from the fastening groove 11.

[0043] This utility model proposes a handheld device comprising a fan body 1 and a handle 2 detachably mounted on the fan body 1. The bottom of the fan body 1 has a locking groove 11, and the handle 2 has a locking mechanism 6. The locking mechanism 6 consists of a push-button switch 61, a locking part 62, and an elastic element 63. The push-button switch 61 is fixedly connected to the locking part 62, and the elastic element 63 is located between the locking part 62 and the handle 2. This structural design enables switching between a locked state and an unlocked state between the locking part 62 and the locking groove 11. When the user presses the button switch 61, it causes the locking part 62 to move downwards, unlocking it from the latching groove 11. At this time, the handle 2 can be detached from the fan body 1, effectively reducing the overall size of the fan, making it easier to store and carry, and improving the product's portability. When the button switch 61 is released, the elastic element 63 uses its own elasticity to drive the locking part 62 upwards, locking it from the latching groove 11, firmly attaching the handle 2 to the fan body 1, ensuring the normal use of the fan. In addition, the handle 2 is equipped with a charging and discharging module 7, which can provide charging services for other electronic devices in outdoor or mobile scenarios, expanding the product's functionality and enhancing its competitiveness in the market. In this embodiment, a motor is installed inside the fan body 1 to drive the fan blades to rotate. The motor is connected to the input terminal 14 at the bottom of the fan body 1 through internal wiring to achieve power input. A battery and a control circuit board are installed inside the handle 2. The battery is electrically connected to the input terminal 14 of the fan body 1 through the output terminal 23, providing stable power to the motor in the locked state. The control circuit board sends speed adjustment commands or mode switching signals to the fan body 1 through the output terminal 23. Furthermore, a nozzle 3 is detachably installed at one end of the fan body 1. Its overall shape is a streamlined hollow cylindrical structure, which is used to effectively guide the airflow generated by the fan to achieve acceleration and concentration, thereby enhancing the wind power.

[0044] Furthermore, the side of the fan body 1 is provided with a first slot 12 and a second slot 13, and the side of the handle 2 is provided with a first locking block 24 and a second locking block 25. The first locking block 24 slides with the first slot 12, and the second locking block 25 is embedded in the second slot 13 when the handle 2 is engaged with the fan body 1. Specifically, when installing the fan, the user aligns the first locking block 24 on the handle 2 with the first locking groove 12 on the side of the fan body 1 and applies a pushing force along the extension direction of the first locking groove 12. At this time, the first locking block 24 enters the first locking groove 12 under the action of the pushing force and slides along its trajectory, providing a guiding function for the installation of the handle 2, enabling the user to find the correct installation direction during the installation process and avoid structural damage or installation failure due to installation deviation. As the handle 2 continues to advance, when the handle 2 and the fan body 1 are close to the fully engaged position, the second locking block 25 on the side of the handle 2 will correspond to the second locking groove 13 on the side of the fan body 1. Under the action of the user continuing to apply the pushing force, the second locking block 25 will be embedded in the second locking groove 13. After embedding, the second locking block 25 and the second locking groove 13 are tightly fitted together, and the mechanical interlock between the two is achieved. The handle 2 is used to effectively restrict multiple degrees of freedom on the fan body 1, preventing it from shaking or falling off during use. This ensures that the handle 2 is firmly installed on the fan body 1, guaranteeing the stability and reliability of the overall fan structure and ensuring stable airflow during operation to meet the user's needs in different scenarios. When it is necessary to remove the handle 2, the user only needs to operate in reverse. First, press the button switch 61 to move the locking part 62 downward, so that the locking part 62 gradually disengages from the fastening groove 11 and unlocks it. After the locking part 62 is unlocked, the user then pulls the handle 2 in the opposite direction of the first slot 12 and the second slot 13, so that the first locking block 24 and the second locking block 25 slide out of the first slot 12 and the second slot 13 respectively, thus removing the handle 2 from the fan body 1. It should be noted that when assembling and disassembling the fan body 1 and the handle 2, users can flexibly choose to do so by pushing and pulling the handle 2 or pushing and pulling the fan body 1, depending on the actual usage scenario, personal operating habits and surrounding environmental conditions.

[0045] Furthermore, a chamfer 121 is provided at the entrance of the first card slot 12, and a guide slope 241 is provided at the end of the first card block 24. Specifically, when installing the fan, the user holds the handle 2 and brings the first locking block 24 close to the first slot 12 on the side of the fan body 1. Since the ends of both are respectively provided with chamfers 121 and guide slopes 241, even if there are some minor deviations during the initial alignment process, such as slight shaking of the user's hand, deviation of the line of sight angle, or inaccurate positioning due to limited operating space, the guide slope 241 of the first locking block 24 will first contact the chamfer 121 at the entrance of the first slot 12. The guide slope 241 slides naturally along the tilt direction of the chamfer 121, automatically adjusting the position and angle of the first locking block 24 so that it slides into the first slot 12. The setting of chamfers 121 and guide slopes 241 reduces the difficulty of installation and avoids problems such as alignment difficulties caused by user unfamiliarity with operation or visual errors, collisions and scratches between the locking block and the edge of the slot, effectively protecting the structural integrity of the first locking block 24 and the first slot 12 and extending the service life of the product. Furthermore, in this embodiment, a chamfer 121 is also provided at the entrance of the second slot 13. The end of the second locking block 25 is set as a matching bevel corresponding to the shape port on the side where the second slot 13 is located on the fan body 1. During installation, after the first locking block 24 slides into the first slot 12, the second locking block 25 contacts the chamfer 121 at the entrance of the second slot 13 through its end bevel and slides into the second slot 13 along the inclined direction of the chamfer 121. The depth of the second slot 13 is slightly greater than the height of the second locking block 25 to ensure a tight mechanical fit when the two are engaged, while reserving a small gap to avoid stress concentration caused by tolerance or thermal expansion and contraction. Furthermore, in other embodiments, a buffer pad can also be provided at the bottom of the second slot 13 to absorb vibration and impact that may occur during use, further protecting the durability of the locking structure.

[0046] Furthermore, the bottom of the fan body 1 is provided with an input terminal 14, and the handle 2 is provided with an output terminal 23. The input terminal 14 and the output terminal 23 are electrically connected in the locked state. Specifically, when the handle 2 is fully locked to the fan body 1, that is, when the handle 2 is securely installed on the fan body 1 through the precise engagement of the first slot 12 and the first locking block 24, the second slot 13 and the second locking block 25, and the locking mechanism 6, the output terminal 23 of the handle 2 and the input terminal 14 at the bottom of the fan body 1 automatically align and make close contact, realizing stable power or signal transmission. Furthermore, the input terminal 14 is connected to the internal circuit of the fan body 1, and the output terminal 23 is connected to the battery or control circuit board built into the handle 2. In the locked state, the handle 2 can supply power to the fan through the output terminal 23 (for example, the lithium battery built into the handle 2 provides power to the fan motor), or transmit control signals (such as commands to adjust the wind speed, switch modes, etc.), thereby realizing multi-speed adjustment and switching of the operating mode of the fan.

[0047] Specifically, the input terminal 14 at the bottom of the fan body 1 is made of a highly conductive and wear-resistant copper alloy. Its surface is finely gold-plated, with a uniform and dense gold plating layer. This not only effectively reduces resistance and energy loss during transmission, improving energy transmission efficiency, but also enhances the terminal's oxidation and corrosion resistance, ensuring good conductivity throughout long-term use. The input terminal 14 is designed as a combination structure with multiple elastic contacts. The input terminal 14 and output terminal 23 use an elastic contact design, ensuring that even with minor assembly tolerances during locking, the offset can be compensated for through elastic deformation, maintaining reliable contact. This electrical connection design, through a coordinated mechanism of mechanical locking and circuit linkage, achieves "plug and play" intelligent operation: the user only needs to physically engage the handle 2 with the fan body 1 to simultaneously activate the power supply or control function, without any additional operation.

[0048] In other embodiments, an insulating protective ring is provided on the outside of the input terminal 14, and the output terminal 23 is correspondingly fitted into the protective ring to form a sealed connection, which effectively prevents dust and moisture from entering and improves durability in outdoor environments.

[0049] Furthermore, the handle 2 is provided with a mounting cavity 21 for the movement of the locking mechanism 6, and the locking mechanism 6 is mounted in the mounting cavity 21. A positioning post 22 is provided in the mounting cavity 21, and the elastic element 63 is sleeved on the positioning post 22. In this embodiment, the mounting cavity 21 is a specific spatial structure integrally injection molded inside the handle 2 housing, and its overall shape is "convex". A guide hole is opened at the top for the locking part 62 to slide through the hole. The locking part 62 slides vertically through the hole. An operation window is opened on the side for the button switch 61 to be exposed. The locking part 62 and the button switch 61 are integrally molded structures. The two move linearly in the vertical direction in the mounting cavity 21. The elastic element 63 is sleeved on the positioning post 22 in the mounting cavity to prevent the elastic element 63 from shifting during the extension and retraction process, and to ensure that the elastic element 63 can always stably drive the locking part 62 to move in the predetermined direction. One end of the elastic element 63 abuts against the lower surface of the locking part 62, and the other end abuts against the bottom cavity wall in the mounting cavity 21 to provide an upward elastic restoring force.

[0050] Furthermore, a guide slope 621 is provided on the side of the locking part 62 facing the installation direction of the fan body 1. In this embodiment, the guide slope 621 is inclined on the side facing the installation direction of the fan body 1, so that when the fan body 1 is pushed toward the handle 2, the locking groove 11 contacts the locking part 62 and presses down the locking part 62, so that the fan body 1 can be smoothly connected to the handle 2 without having to press the button switch 61 to complete the installation, simplifying the operation steps, improving the user experience, and making the installation of the fan body 1 more convenient and efficient.

[0051] Furthermore, the push-button switch 61 is provided with anti-slip protrusions. In this embodiment, the push-button switch 61 is provided with anti-slip protrusions, which are evenly distributed on the surface of the push-button switch 61 in a wavy, dotted, or horizontal stripe shape. When the user presses the push-button switch 61, the anti-slip protrusions increase the friction of the contact surface, effectively preventing pressing errors caused by slippage due to wet or oily hands or wearing gloves.

[0052] Furthermore, a wind speed adjustment switch 4 and a control switch 5 are provided on the surface of the fan body 1. In this embodiment, the wind speed adjustment switch 4 and the control switch 5 are electrically connected to the control circuit board provided in the handle 2. The wind speed adjustment switch 4 and the control switch 5 are arranged opposite to each other, that is, the wind speed adjustment switch 4 is located on the front side of the fan body 1, and the control switch 5 is located on the rear side of the fan body 1. This arrangement allows the user to easily touch the wind speed adjustment switch 4 with their right index finger and simultaneously touch the control switch 5 with their right thumb when using the fan, without having to move their wrist significantly. Furthermore, a display screen 8 is also provided on the side of the fan body 1 to display the current fan speed and mode, allowing the user to intuitively observe the current operating status of the fan. In other embodiments, the fan body 1 may also be provided with LED indicator lights to provide real-time feedback on the current operating status.

[0053] Furthermore, the handle 2 is also equipped with a charging / discharging module 7. In this embodiment, the charging / discharging module 7 is located at the bottom of the handle 2, and the charging / discharging module 7 is equipped with a charging / discharging interface. The charging / discharging interface is used to charge external electronic devices during discharge, or to charge the battery inside the handle 2 during charging. By setting up the charging / discharging module 7, the handle 2 can be used as a power bank when it is separated from the fan body 1, expanding the product's functional practicality and enhancing its competitiveness in the market. The charging / discharging interface can be a Type-C interface, a Micro-B interface, or other interface types.

[0054] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. All equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
