However, this type of handheld fan generally has the following technical problems: Existing handheld fans can only realize the cooling function by blowing air and cannot provide emergency charging services for small electronic devices such as users' smartphones and earphones. Users have to carry a handheld fan and a mobile battery outdoors at the same time, which increases the travel burden and reduces the convenience of use. [[ID=I19]] The present invention has been made in view of the above situation and provides a handheld fan with a charging function.

[Modes for carrying out the invention]

[0011] The embodiments of the present invention will now be described in detail. It goes without saying that the embodiments described are not all embodiments of the present invention, but rather only some embodiments. It goes without saying that any other embodiments obtained by a general person of the art without any creative ingenuity based on the embodiments of the present invention are also included within the scope of the claims of the present invention. [Examples]

[0012] The embodiments of the present invention will be described in detail below. The handheld fan with charging function according to the present invention comprises the following components: Casing: Composed of a front case and a rear case, the front case is formed by integrally molding a first fan case (3) and a first grip case (4), and the rear case is formed by integrally molding a second fan case (5) and a second grip case (6). A first snap (12) and a first snap hole (13) are integrally molded on the opposing surfaces of the first fan case (3) and the second fan case (5), respectively. When the front case and the rear case are fitted together, the first snap (12) fits into the first snap hole (13), achieving accurate positioning and a firm connection of the fan case portion. Correspondingly, a second snap (14) and a second snap hole (15) are integrally molded on the opposing surfaces of the first grip case (4) and the second grip case (6), respectively. When the front case and the rear case are fitted together, the second snap (14) fits into the second snap hole (15), achieving a firm connection of the grip case portion. To optimize the interface placement, the charging interface (10) is embedded directly onto the second snap (14), and the snap structure provides a certain level of protection to the interface, reducing erosion from dust and moisture. The fan unit (1) is fitted inside the first fan case (3) and the second fan case (5), and is powered by the storage battery (2) to rotate and provide airflow. Both the first fan case (3) and the second fan case (5) have multiple ventilation holes, which are provided in conjunction with the air outlets of the fan unit (1) to ensure smooth airflow and improve the cooling effect of the fan. The circuit board includes a charging module (7) and a discharging module (8). The charging module (7) has the function of receiving power from an external power source and charging the storage battery (2), and the discharging module (8) has the function of supplying power from the storage battery (2) to external electronic devices. To optimize the internal space arrangement, the charging module (7) and the discharging module (8) are embedded and mounted at the upper and lower ends inside the first grip case (4) and the second grip case (6), respectively. Battery (2): Fitted in the middle inner position of the first grip case (4) and the second grip case (6), and electrically connected to the charging module (7) and the discharge module (8), respectively, to store and supply power. To prevent the battery (2) from shaking inside the casing, position limiting plates (16) are integrally molded on the inner surfaces of both the first grip case (4) and the second grip case (6). After the front case and rear case are fitted together, the two sets of position limiting plates (16) surround each other to form a position limiting space that matches the outer shape of the battery (2), and the position limiting plates (16) are in close contact with the outer surface of the battery (2), achieving stable position limiting of the battery (2). Operation and Interface Components: A button (9) is embedded in the front of the first grip case (4). The button (9) is electrically connected to a circuit board and used to control the starting and stopping of the fan unit (1) and the switching of the charge and discharge functions. A charging interface (10) is provided on the side of the first grip case (4) at a position corresponding to the charging module (7) and is used to charge the battery (2) by connecting an external power supply. A positioning plate (17) is provided at the lower end of the second grip case (6). When the front case and rear case are fitted together, the lower end of the first grip case (4) is coupled to the positioning plate (17), further improving the connection stability of the entire casing. The discharge interface (11) is embedded on the positioning plate (17) to make it easier for the user to connect a data cable and to avoid damage to the interface due to gripping. Base (19): It is provided below the casing and is slidably connected to the lower end of the casing and the upper end surface of the base (19). When not in use, the casing can be slid onto the base (19) and fixed by coupling, which can prevent the fan from falling over and is convenient for storage.

[0013] Operating principle The operating principle of the present invention is mainly composed of the process of "charging - power storage - discharging / blowing". When charging, an external power cord is connected to the charging interface (10), and power is transmitted to the battery (2) through the charging module (7) to store power in the battery (2). When using the blowing function, press the button (9) to start the fan unit (1), supply power from the battery (2) to the fan unit (1), and the fan unit (1) rotates to blow air. When using the emergency charging function, press the button (9) to switch the charging and discharging function, connect the data cable of an external electronic device to the discharging interface (11), and the power stored in the battery (2) is transmitted to the external electronic device through the discharging module (8) to achieve charging.

[0014] Since each part of the casing adopts a combination method of snap - fitting and coupling connection, assembly and disassembly are simple. When maintenance is required, simply manually separate the front case and the rear case, and the components such as the internal fan unit (1), circuit board, battery (2), etc. can be taken out for inspection, repair or replacement, greatly improving the convenience of maintenance.

[0015] The positioning pins (18) are integrally formed at both upper and lower ends of the inner surface of the second grip case (6). When installing the charging module (7) and the discharging module (8), the positioning pins (18) are inserted into the positioning holes on the module to achieve accurate positioning of the module, prevent displacement after installation, and ensure the stability of electrical connection.
