In the description of the present invention, it should be noted that the terms “install”, “link” and “connect” should be understood in a broad sense unless otherwise specified and defined. For example, “connect” may be fixed connection, detachable connection or integrated connection; or, mechanical connection or electric connection; or, direct connection, indirect connection through intermediate media or internal communication of two elements or interaction of two elements. For those of ordinary skill in the art, the specific meaning of the terms mentioned above in the present invention should be construed according to specific circumstances.

As shown inFIGS.1-11, a string light controller with a charging function provided by this embodiment comprises a shell1, wherein a main board2and a rechargeable battery3electrically connected with the main board2are installed on the shell1, the main board2is connected with the rechargeable battery3through a battery charging and discharging management circuit4, and the main board2is provided with a charging socket5connected with the battery charging and discharging management circuit4; and a port of the charging socket5is arranged outside the shell1, a plug6for connecting a string light is arranged on the shell1, and the plug6is electrically connected with the main board2.

This embodiment involves the installation of the rechargeable battery3within the string light controller, along with the necessary circuits to enable charging. This design allows the string light controller to function as both a power source and a charger. In this way, regardless of the presence of electrical sockets, portable power supplies, or battery holders, a string light can be used normally anytime and anywhere, whether indoors or outdoors. This feature greatly benefits market promotion and daily applications.

Further, to facilitate the indication of internal working status, such as battery level indication, remote control, and manual switching, the main board2is provided with indicator light beads7, an infrared receiving module8for receiving infrared signals and buttons9for user operation, and the shell1is provided with corresponding hollowed-out parts10at positions exactly opposite to the light beads7, the infrared receiving module8and the buttons9. The hollowed-out parts10allow light to be directed outwards, external infrared signals to be transmitted to the inside, and pressing rods of the buttons9to extend out for operators to press. Meanwhile, to prevent the intrusion of foreign matter through the hollowed-out parts10, a light-pervious cover plate11is arranged at the hollowed-out parts10of the shell1, the cover plate11is provided with raised pressing caps12at positions corresponding to the buttons9, and the pressing caps12abut against the pressing rods of the buttons9. This approach enables both effective blocking and the unobstructed functioning of internal components. The cover plate11can be made of a plastic material.

Similarly, for the purpose of protection, the shell1is provided with a soft rubber plug13for sealing the charging socket5at the position of the charging socket5.

Moreover, with regard to the circuit system design, the main board2is further integrated with a main control chip100, a standby low-power control circuit101, a booster circuit102and a string light driving circuit103; the battery charging and discharging management circuit4comprises a battery protection circuit104and a charging protection circuit105, one end of the battery protection circuit104is connected with the rechargeable battery3, and the other end of the battery protection circuit104is connected with the charging protection circuit105and outputs a working power supply; and the main control chip100is connected with the infrared receiving module8, the light beads7, the buttons9, the charging protection circuit105, the standby low-power control circuit101and the string light driving circuit103. During actual operation, the battery protection circuit104and the charging protection circuit105play a role in protecting the rechargeable battery3, ensuring normal power output and charging. The standby low-power control circuit101is mainly composed of a MOS transistor, and the main control chip100controls on-off of the MOS transistor, so as to activate the booster circuit102. In this embodiment, the booster circuit102can adopt various circuit structures, such as the circuit structures shown inFIGS.8and9. After the booster circuit102inputs voltage-boosted power to the string light driving circuit103, the string light driving circuit103, upon receiving PWM signals from the main control chip100, controls the operation of internal transistors. Ultimately, the power required for string light operation is input to the plug6used for connecting a string light. The specific structure of the plug6depends on the connection design of the string light and is typically an aviation plug or a DC plug. The display of the battery level is managed by the feedback from the battery charging and discharging management circuit4. Then, the main control chip100lights up the corresponding light beads7to indicate the battery level. Additionally, working modes can be displayed. For example, the light beads7arranged in the pattern of the figure eight can form numbers corresponding to specific modes. The corresponding numbers are displayed by lighting up the corresponding light beads7.

Further, in order to protect the plug6, the shell1is provided with a cover14at the position of the plug6.

Moreover, for easy suspension, one end of the shell1is further provided with a suspension loop15, and the suspension loop15is hinged to the shell1, allowing the string light controller to be hung at a high position during practical application.

As shown inFIGS.12and13, this embodiment also provides a charging dock for charging the string light controller as described above, which comprises a base201, wherein at least one slot202allowing the string light controller to be inserted therein is arranged on the base201, a charging plug203mating with the charging socket5of the string light controller is arranged in the slot202, a power socket204for connecting an external adapter is arranged on the base201, and all the charging plugs203are connected with the power socket204. When the battery of the string light controller is low, it can be placed in the slot202, allowing the charging socket5of the string light controller to mate with the charging plug203. Afterwards, the power socket204on the base201can be connected to an external adapter to charge the string light controller.

The above are only preferred embodiments of the present invention, which do not limit the patent scope of the present invention. Any equivalent structure or equivalent flow transformation made according to the contents of the specification and drawings of the present invention, or directly or indirectly applications to other related technical fields should also fall within the patent protection scope of the present invention.
