[0027] To illustrate the technical solution of the above utility model in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the present utility model and not to limit the scope of the present utility model.

[0028] The multifunctional power supply device provided by this utility model, such as Figures 1 to 6 As shown, it includes a battery compartment 10 and a male connector 20, wherein:

[0029] Please refer to this carefully. Figure 3 and Figure 4 The battery compartment 10 includes a shell 11, a battery 12, and a copper cap 13. The battery 12 is housed in the compartment formed by the shell 11 and the copper cap 13. The copper cap 13 is connected to the negative terminal of the battery 12. The center of the copper cap 13 is provided with a through hole 14, and the positive terminal of the battery corresponds to the through hole 14. A first annular magnet 15 is provided inside the copper cap 13.

[0030] Please refer to this carefully. Figure 5 and Figure 6 The male connector 20 includes a bracket 21, a spring pin 22, and a second annular magnet 23. The second annular magnet 23 is disposed inside the bracket 21 and is positioned opposite to the first annular magnet 15. The male connector 20 is positioned and connected to the battery compartment 10 by mutual attraction between the first annular magnet 15 and the second annular magnet 23. The spring pin 22 is installed in the center of the bracket 21 and can be inserted into the through hole 14 to connect with the positive terminal of the battery 12.

[0031] In this invention, after the first annular magnet 15 and the second annular magnet 23 are aligned and attracted, the spring pin 22 in the male connector 20 is inserted into the through hole 14 to achieve connection. At this time, the circuit is connected, and the electronic product can be used normally. When the battery is too low, simply replace it with a new, fully charged battery compartment 10 to continue using the electronic product, while the replaced battery compartment 20 can be recharged. In this structure, one battery compartment 10 can also be connected to multiple electronic products, thus carrying more small electronic products in the same volume.

[0032] In some embodiments, the male connector 20 can be detachably connected to a modular functional head (not shown) of an electronic product (not shown). Specifically, the male connector 20 can be detachably connected to the modular functional head via a snap-fit ​​structure or a magnetic structure. In some embodiments, the electronic product can be a power bank, emergency power bank, air pump, flashlight, razor, hair clipper, hair dryer, electric toothbrush, hair straightener, etc. One end of the modular functional head is connected to the male connector 20, and the other end is connected to the corresponding electronic product. This utility model sets the battery compartment 10 of various small electronic products into a unified structure, allowing companies to focus on the main functions of electronic products and develop more low-cost and high-quality products.

[0033] In some embodiments, please refer to the following: Figure 4 A protection plate 16 is provided between the battery 12 and the copper cap 13 to protect the battery cell of the battery 12 and maintain the safety and stability of the battery 12 during charging and discharging.

[0034] In some embodiments, please refer to Figure 4 An insulating ring 17 is installed on the side wall of the through hole 14 to prevent short circuits caused by metal objects adsorbed inside the through hole 14.

[0035] In some embodiments, the second annular magnet 23 is embedded within the bracket 21, and the inner diameter of the bracket 21 is larger than the outer diameter of the copper cap 13. In other words, the bracket 21 can extend to cover the outside of the copper cap 13, preventing collisions from causing the battery compartment 10 to detach from the male connector 20, or even damaging components such as the spring pin 22. In some embodiments, the outer diameter of the bracket 21 is equal to the outer diameter of the outer shell 11, meaning that the copper cap 13 is retracted inward relative to the outer shell 11, thus maintaining the consistency and continuity of the appearance of the bracket 21 and the outer shell 11.

[0036] In some embodiments, the surfaces of the first annular magnet 15 and the second annular magnet 23 are plated with copper to improve the magnet's corrosion resistance, reduce surface defects, reduce the shielding effect on magnetism, and help maintain the magnet's original shape.

[0037] In some embodiments, the bottom of the housing 11 is provided with a charging interface (not shown) that communicates with the battery 12, for connecting a charging cable to charge the battery 12 inside the battery compartment 10.

[0038] In summary, the multifunctional power supply device provided by this utility model includes a battery compartment 10 and a male connector 20. The battery compartment 10 includes a housing 11, a battery 12, and a copper cap 13. The battery 12 is housed within the compartment formed by the housing 11 and the copper cap 13. The copper cap 13 is connected to the negative terminal of the battery 12. A through hole 14 is provided in the center of the copper cap 13, and the positive terminal of the battery corresponds to the through hole 14. A first annular magnet 15 is provided inside the copper cap 13. The male connector 20 includes a bracket 21, a spring pin 22, and a second annular magnet 23. The second annular magnet 23 is disposed inside the bracket 21 and is positioned opposite to the first annular magnet 15. The male connector 20 is positioned and connected to the battery compartment 10 by the mutual attraction and positioning of the first annular magnet 15 and the second annular magnet 23. The spring pin 22 is installed in the center of the bracket 21 and can be inserted into the through hole 14 to connect with the positive terminal of the battery 12. In this invention, the battery compartment 10 and the connecting male connector 20 are attracted and fixed together by the first annular magnet 15 and the second annular magnet 23, which facilitates the installation and removal of the battery compartment 10. At the same time, the connecting male connector 20 can be detachably connected to a variety of electronic products, so that one battery compartment 10 can be equipped with a variety of electronic products, thereby carrying more small electronic products in the same volume.
