[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a portable fan with a detachable battery, including a handheld shell 1 with a battery installed and a fan body 2. The top of the handheld shell 1 is provided with a connecting groove, and one end of the connecting groove has an opening that communicates with the outside of the handheld shell 1. The bottom of the fan body 2 is provided with a connecting seat 3, which is slidably installed in the connecting groove. The connecting groove is provided with a locking mechanism for locking the connecting seat 3 near its opening end. The other end of the connecting groove is provided with two sets of spring pins 11, and one side of the connecting seat 3 is provided with a copper sheet that contacts the spring pins 11. The inside of the handheld shell 1 is provided with a control motherboard, and one side of the control motherboard is provided with multiple sets of sockets 12 for external discharge.

[0026] The connecting groove has an inverted T-shaped cross section, and the connecting seat 3 has a cross section that matches the connecting groove, making the connecting seat 3 more stable and reliable when sliding inside the connecting groove. This improves the overall structural stability of the product, makes operation simple and convenient, and enhances the user experience.

[0027] The connecting groove has an installation slot near its opening end. The locking mechanism includes a telescopic rod 4 fixed inside the installation slot. The top of the telescopic rod 4 is connected to a limit plate 5, and the top of the limit plate 5 is connected to a locking block 6. The top of the installation groove has a through groove for the locking block 6 to protrude. The side of the locking block 6 at the top is in contact with an outer side wall of the connecting seat 3. One side of the locking block 6 has an inclined surface, which faces away from the connecting seat 3, thus locking the connecting seat 3 and further enhancing the stability of the connection between the fan body 2 and the handheld shell 1, ensuring that the fan body 2 will not loosen or fall off during operation.

[0028] The telescopic rod 4 is fitted with springs 7 on its outer side, and both ends of the springs 7 are respectively abutted against the inner sidewall of the limiting plate 5 and the mounting groove. The handheld housing 1 has a sliding groove on one side of the through groove. One side of the limiting plate 5 extends to the outside of the sliding groove and is fixedly installed with a sliding key 8. The surface of the sliding key 8 is provided with anti-slip texture. The elastic force of the springs 7 provides continuous upward support for the locking block 6, ensuring that the locking block 6 and the connecting seat 3 are stably and reliably engaged. The user can press the sliding key 8 to move the limiting plate 5 along the sliding groove, thereby controlling the lifting and lowering of the locking block 6, which improves the convenience of disassembly operation.

[0029] One end of each spring pin 11 is electrically connected to the control motherboard via a wire; the connector 3 has a circuit board inside, and the copper sheets are electrically connected to the circuit board via wires. With the cooperation of the spring pin 11, the control motherboard, the circuit board, and the copper sheets, a stable conductive path can be formed, thereby providing power support for the operation of the fan body 2.

[0030] The handheld casing 1 has a control button 9 installed on its outer side, and the control button 9 is electrically connected to the control motherboard, which makes it easy for the user to operate with one hand when holding the device. The rotation state of the fan body 2 can be adjusted in real time to meet the wind power requirements in different scenarios, and enhance the human-computer interaction performance and usage flexibility of the device.

[0031] The handheld casing 1 has multiple sets of power indicator lights 10 located on the outer side and below the control button 9. These multiple sets of power indicator lights 10 are retractable and electrically connected to the control motherboard. The power indicator lights 10 can provide real-time and intuitive feedback on the remaining power of the device, helping users to keep track of the battery's remaining power status, plan charging time or usage time reasonably, and avoid affecting the user experience due to the battery running out.

[0032] The working principle of this embodiment:

[0033] When the fan body 2 needs to be used, first align the connecting seat 3 at the bottom of the fan body 2 with the connecting groove at the top of the handheld shell 1, and push it along the groove direction. During the movement of the connecting seat 3, it presses the inclined surface of the locking block 6, forcing the locking block 6 to move downward against the elastic force of the spring 7. The telescopic rod 4 is compressed. When the connecting seat 3 slides to the preset position, the locking block 6 rises with the telescopic rod 4 under the restoring force of the spring 7. The top of the locking block 6 fits against the outer wall of the connecting seat 3, thus locking and fixing the fan body 2. At this time, the copper plate on one side of the connecting seat 3 is fully connected to the spring pin 11 inside the handheld shell 1. Since the circuit board inside the connecting seat 3 is electrically connected to the motor of the fan body 2 through the wire, a conductive path is formed, which facilitates the power supply to the fan body 2. The user sends a signal to the fan body 2 through the control button 9 to adjust the speed of the fan body 2. The power indicator light 10 can display the remaining power in real time. Different colors or numbers of lights correspond to different power ranges, which is convenient for the user to view intuitively.

[0034] When the fan body 2 is not in use and is being disassembled, the user first presses the sliding key 8. The sliding key 8 moves the limiting plate 5 downward along the sliding groove, the telescopic rod 4 is compressed, and the locking block 6 descends synchronously with the limiting plate 5 until it is separated from the outer wall of the connecting seat 3. At this time, the connecting seat 3 loses the limiting effect of the locking block 6 and can be slid out along the connecting groove, realizing the separation of the fan body 2 from the handheld shell 1. During the disassembly process, the spring pin 11 is disconnected from the copper sheet, and the circuit is cut off. At the same time, the socket 12 on one side of the handheld shell 1 can not only be used as a charging interface to charge the battery, but also as an output interface to power other electronic devices.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
