Such electrically heated clothing mainly provides heat through built-in heating elements, solving the problem that traditional warm clothing is limited by the external environmental temperature and is particularly useful in low-temperature environments.

[0003] Existing electrically heated clothing mostly relies on large power banks or external power sources. Such power banks are mainly for general use and are usually used for the charging needs of various electronic devices, including mobile phones, tablets, and other portable devices. Although these power banks can provide sufficient power for clothing heating, due to their large size and heavy weight, they are not suitable for being built into clothing, especially in outdoor or scenarios where they need to be carried around, their portability and comfort are poor. In addition, the waterproof design of general-purpose power banks is relatively weak, and only a few high-end products are equipped with waterproof casings, which poses a great safety hazard when used in humid environments. Moreover, the internal structure of such devices is relatively complex, and some products are easily affected by the humid environment during use due to insufficient sealing, resulting in short circuits or performance degradation, affecting user safety and service life. How to invent a waterproof and moisture-proof portable charging device to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0021] Furthermore; a groove 102 adapted to the charging interface 4 is opened on the outer wall of the bottom case 1, a limiting rib 7 is fixedly connected to the inner wall of the bottom case 1, a baffle 10 is fixedly connected to the inner wall of the bottom case 1, and the limiting rib 7 and the baffle 10 are respectively located on both sides of the battery 9; the main board 8 is clamped with the limiting rib 7, the side wall of the main board 8 is fixedly connected with the charging interface 4, and one end of the charging interface 4 is located inside the groove 102; an installation hole 101 is opened on the side wall of the bottom case 1, a socket 6 is fixedly connected to the inner wall of the bottom case 1, the length of the socket 6 is less than the depth inside the bottom case 1, and one end of the socket 6 is connected with the installation hole 101.

[0022] Limiting ribs 7 and baffle 10 limit the main board 8 and the battery 9 respectively: The whole device is circularly arranged. During installation, the main board 8 can be clamped between the two limiting ribs 7. The limiting ribs 7 are arranged in a "V" shape, while the battery 9 is placed between the limiting ribs 7 and the baffle 10. In addition, the two sides of the battery 9 can be restricted by the two socket connectors 6 to complete the positioning of the battery 9. Subsequently, when installing the bottom shell 1 and the outer shell 2, the two docking columns 11 can be respectively inserted into the two socket connectors 6, and then one end of the fastening screw 5 is passed through the mounting hole 101 and threadedly connected to the docking column 11 and the socket connector 6 to complete the fixed installation of the bottom shell 1 and the outer shell 2; The bottom shell 1 and the outer shell 2 are made of high-strength plastic materials and fixed by multiple fastening screws 5, which can form a strong protective shell and have good waterproof performance. The overall diameter can be 90 - 100 mm, and the height can be 12 - 13 mm. In addition, a light-transmitting window is provided on the side wall of the outer shell 2 to display the status of the internal power indicator board. The power indicator board is located below the outer shell 2 of the charging device and cooperates with the external light-transmitting window, enabling users to intuitively and conveniently observe the power status.

The charging interface 4 can adopt a Type-C interface, which has strong compatibility and supports plugging and unplugging in both directions, facilitating user operation. The design of the groove 102 effectively prevents the problem that the charging cable cannot be inserted properly due to the overall arc shape of the device, ensuring a smooth charging process; When in use, the charging cable can be inserted into the charging port 4 at the bottom of the device, ensuring that the charging cable is completely embedded in the groove 102 to charge the battery 9. Then, the display status of the power light board can be observed through the light-transmitting window. After confirming that the power is full, the device can be connected to the heating element of the clothing and the heating function can be turned on. When the device is not in use, it can be stored in a dry and ventilated environment to avoid high temperature and high humidity conditions. At the same time, try to avoid being squeezed by heavy objects or falling from heights to prevent damage to the outer shell 2 and internal components. During maintenance, the charging port 4 and the light-transmitting window should be cleaned regularly to prevent dust accumulation from affecting normal functions.

One end of the telescopic cylinder 31 will contact the side wall of the battery 9. As the fastening screws 5 are tightened, the outer shell 2 gradually approaches the bottom shell 1, and then the side wall of the battery 9 squeezes the telescopic cylinder 31. At this time, the telescopic cylinder 31 will shrink, and the air inside it will pass through the through hole 35 and the vent 201. The liquid is discharged into the interior of the sealing airbag 32, so that the sealing airbag 32 expands and inflates. The sealing airbag 32 is elastic, and the convex ring 104 cooperates to further improve the sealing of the connection between the bottom shell 1 and the outer shell 2, thereby improving the waterproof and moisture-proof effect. After the equipment is installed, the elasticity of the telescopic cylinder 31 can support the side wall of the battery 9, thereby increasing the stability of the battery 9 after installation and reducing the occurrence of offset and shaking. In addition, after the installation is completed, one end of the heat-conducting rod 33 will extend out of the piston ring 34 and be located on the outside of the outer shell 2. When the equipment generates heat during operation, part of the heat can be discharged to the outside of the equipment through multiple heat-conducting rods 33 to reduce heat accumulation and ensure the normal use of the internal components of the equipment. The heat-conducting rod 33 can be made of metal, such as copper or aluminum, but not limited to this.
