[0014] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-Figure 3 As shown, a waterproof battery assembly of this embodiment includes a shell 1 and a battery cell 2 arranged in the shell 1, the shell 1 has a receiving groove 11, and the battery cells 2 are multiple, and the multiple battery cells 2 are all arranged in the receiving groove 11. A sealing head 3 is provided at the opening of the receiving groove 11, and a balancing circuit board 4, a display screen 5, and a switch 6 are provided on the sealing head 3. The balancing circuit board 4 is connected to the battery cell 2, the display screen 5 and the switch 6. The top of the sealing head 3 is provided with a positive and negative terminal 7, and the positive and negative terminal 7 is connected to the battery cell 2.

[0016] The above-described technical solution provides a rod-shaped waterproof battery assembly that can be installed inside a shark repellent or fishing rod without affecting operation and provides high stability. Furthermore, the assembly can also be attached to the outside of the rod for use. The battery cells 2 are arranged continuously within the receiving slot 11. When replacing batteries on a shark repellent or fishing rod, simply remove the entire waterproof battery assembly and replace it with a fully charged one, eliminating the need to repeatedly remove and replace individual batteries. This improves replacement efficiency.

[0017] Specifically, a balancing circuit board 4 is used, which has overcharge protection, over-discharge protection, short circuit protection, overload protection, over-temperature protection, and balanced charging functions, is safer and more reliable, and avoids the problem of voltage difference between each battery cell after the battery discharge process, ensuring the capacity and power of the battery pack during recycling, extending the battery life, and ensuring the battery output power.

[0018] The waterproof battery assembly can be turned on by pressing the switch 6. The balancing circuit board 4 reads the voltage and power status of all battery cells 2 and displays them on the display screen 5 for easy use.

[0019] After the waterproof battery assembly is installed in the shark-proof rod or fishing rod, the positive and negative terminals 7 are connected to the internal circuit of the shark-proof rod / fishing rod to provide power. This ensures high stability and does not affect operation. The positive and negative terminals 7 are connected to the internal circuit of the shark-proof rod / fishing rod to improve stability and prevent circuit breakage caused by vibration.

[0020] As an improved specific implementation, the sealing head 3 is integrally packaged and connected to the shell 1 by ultrasonic welding.

[0021] Through the above technical solution, the sealing head 3 is integrally packaged and connected to the shell 1 through ultrasonic welding, which has good sealing performance, durability and drop resistance.

[0022] As an improved specific implementation, a connecting groove 12 is provided at the opening of the accommodating groove 11 , and a connecting portion 31 is provided on the sealing head 3 , and the connecting portion 31 extends into the connecting groove 12 .

[0023] Through the above technical solution, the connecting portion 31 extends into the connecting groove 12 to connect the shell 1 and the sealing head 3, thereby increasing the connection strength and further improving the drop resistance.

[0024] As an improved specific implementation, the connecting portion 31 interferes with the battery unit 2 .

[0025] Through the above technical solution, the connecting portion 31 interferes with the battery unit 2, restricting the position of the battery unit 2 and preventing the battery unit from moving, thereby improving stability during use.

[0026] As an improved specific implementation, shock-absorbing cotton 8 is provided in the receiving groove 11.

[0027] Through the above technical solution, the provision of the shock-absorbing cotton 8 further improves the drop resistance and the stability during use.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
