[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figure 1-5 As shown, a multi-functional flashlight includes a battery body 1, a lamp head heat sink 4, a focusing lens body 5, a yellow light filter body 6, and a window breaker 7. The front end of the battery body 1 is threadedly connected to the flashlight body 3, and the rear end of the battery body 1 is threadedly connected to a tail cap 2. The rear end of the tail cap 2 has a mounting groove 21, in which an N54 magnet 18 is installed. A single magnet can provide a vertical attraction force of ≥8kg, which is sufficient to firmly attach to curved surfaces such as car hoods and iron pipes. When the flashlight is turned on, it can be used as a maintenance lamp, work lamp, etc., achieving "free hanging lighting" and freeing up the hands. The rear end of the tail cap 2 has a threaded groove 22 that fits outside the mounting groove 21, and a battery 1 is installed inside the battery body 1. 7. The battery 17 uses a brand new EVE Energy ICR18650 / 3.6V / 2500mAh A-stick battery. A switch 16 is provided on the outside of the flashlight body 3. A spiral groove 31 is provided on the front side of the outer surface of the flashlight body 3. A spiral block 41 is provided on the rear side of the inner wall of the lamp head heat sink 4. The lamp head heat sink 4 is sleeved on the front side of the outer surface of the flashlight body 3, and the spiral block 41 slides in the spiral groove 31 to achieve focus adjustment. The lamp head heat sink 4 has a thread inside. The lamp bead locking ring 13 is threaded to fix the plano-convex lens 12 in the lamp head heat sink 4. An lamp bead 10 is installed in the middle of the front end of the flashlight body 3. A lamp bead centering cover 11 is provided on the outside of the lamp bead 10.
[0022] The rear end of the tail cap 2 can be threadedly connected to any of the following: the focusing lens barrel 5, the yellow light filter barrel 6, or the window breaker 7. The focusing lens barrel 5, the yellow light filter barrel 6, and the window breaker 7 can be threaded together. When the flashlight is not in use, the focusing lens barrel 5 and the yellow light filter barrel 6 can be installed sequentially at the rear end of the tail cap 2, and then the window breaker 7 can be installed. Unused barrels can be screwed to the tail cap 2 for storage, preventing the loss of parts. In an emergency where the car door cannot be opened and escape is required, the rear window breaker 7 can be used to break the car window glass for escape. It can also be used as a self-defense weapon in other emergency situations. The window breaker 7 is made of stainless steel with embedded silicon nitride material, which has both high hardness and high temperature resistance, and can break car windows or be used as a self-defense tool.
[0023] The front end of the lamp head heat sink 4 can be threadedly connected to any of the focusing lens body 5, the yellow light filter body 6, or the window breaker 7. Users can quickly switch functions according to their needs. In rainy or foggy weather, the yellow light filter body 6 can be threadedly connected to the front end of the lamp head heat sink 4 to enhance the penetration of rain and fog through a wavelength of 585-595nm, serving as a warning light. It can also be used as a camping light or other daytime light when lit with a diffuser. When the focusing lens body 5 is threadedly connected to the front end of the lamp head heat sink 4, it can act as an igniter. The specific steps are: Step 1 First, screw the focusing lens body 5 onto the head of the lamp head heat sink 4. Second, rotate the telescopic adjustment to adjust the focus to the highest position. Third, in the lit state, press and hold the power button 16 to enter the ultra-bright mode. Place a dark object on the focus point (the focus point is about 1cm above the focusing lens) to ignite the dark object, such as lighting a cigarette. Alternatively, connect the window breaker 7 to the front thread of the lamp head heat sink 4, press and hold the power button 16 to enter the ultra-bright mode. The LED light source dissipates heat, and the window breaker 7, with its metal structure, absorbs heat and can be used as a miniature power bank.
[0024] A charging interface 14 is provided on the lower part of the outer surface of the flashlight body 3. The charging interface 14 supports UtoC / CtoC one-way charging. The universal interface design is compatible with a variety of charging devices, enhancing user convenience. A recessed area 32 is provided on the outer periphery of the charging interface 14. A dustproof silicone cover 15 is connected inside the charging interface 14. The dustproof silicone cover 15 is adapted to the recessed area 32. The dustproof silicone cover 15 effectively blocks dust and moisture, avoids interface corrosion, and improves reliability in outdoor environments.
[0025] The battery body 1, tail cap 2, and flashlight body 3 are all provided with anti-slip sealing silicone rings 8, which not only prevent the flashlight from slipping off accidentally, but also prevent moisture from seeping into the body 1, thus improving durability. The silicone material increases friction, making it suitable for stable grip in humid or oily environments.
[0026] The flashlight body 3 houses a switch circuit board 9, and the power switch 16 is electrically connected to the switch circuit board 9. The switch circuit board 9 supports single-click and long-press operations to switch between high brightness, low brightness, strobe, and SOS modes. The ultra-bright mode lasts for 20 seconds, and multiple brightness levels are adjustable to meet different needs. Specifically, a single click of the power switch 16 turns the flashlight on or off. In any illuminated mode, a long press of the power switch 16 enters the ultra-bright mode, lasting 20 seconds, after which it automatically returns to the previous mode. Releasing the power switch 16 within 20 seconds also returns to the previous mode. In the off state, a long press of the power switch 16 enters the strobe mode, and releasing it turns off the light. In the off state, a single click of the power switch 16 turns on the high brightness mode. After entering high brightness mode, pressing it again within 5 seconds enters low brightness mode; after entering low brightness mode, pressing it again within 5 seconds enters strobe mode. In the normal sequence of brightness levels, when in strobe mode, pressing it again within 5 seconds enters SOS mode. The sequence of light levels is: single button press → high brightness → low brightness → strobe → SOS. To adjust the corresponding lighting mode, press the button again within 5 seconds of the last button press. Pressing the button again after 5 seconds will turn off the light.
[0027] The front end of the outer surface of the lamp head heat sink 4 is fitted with a diffuser 19, which softens the light and can be used as a camping lamp or household lighting to reduce the problem of strong light glare.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
