A switch button 90 and an SOS button 91 are provided on the key panel 9, and the upper ends of the switch button 90 and the SOS button 91 extend out of the barrel body 1. A battery 10 is also provided inside the barrel body assembly, and the battery 10 is fixed in the barrel seat 7 and is used to power the light board 4. The control panel 8 is also provided with a charging port, which can be connected to the mains to charge the battery 10. In the running state and the charging state, short press the switch button 90 once, and the flashlight turns on the default low brightness gear, medium brightness gear, high brightness gear, and shut down in sequence; short press the SOS button 91 once to turn on the strobe mode, and press it again to switch to the SOS mode, and cycle in sequence.

[0028] In order to improve the waterproof performance, the lens 3 is fixed in the front end of the focus ring 2 through the front cover 11, and waterproof rubber rings 12 are provided inside the focus ring 2 and outside the heat sink 5 to prevent external moisture from entering the inside of the barrel 1.

[0029] In addition, the flashlight also includes a hook 13, which is plugged and fixed on the other end of the barrel 1, and the hook 13 includes a fixed part 130 and a rotating part 131. The rotating part 131 is rotatably connected to the fixed part 130, and a notch is formed by pressing the rotating part 131. Therefore, the flashlight can be easily hung on a backpack or other supplies, and is also convenient for taking out. At the same time, different irradiation areas and different light intensities can be realized through adjustment and button operation to meet a variety of usage scenarios.

[0030] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
