[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a laser flashlight, comprising a body 1, a head 2 rotatably connected to the top of the body 1, allowing the head 2 to rotate relative to the body 1 for easy adjustment of the light emission direction, a lamp holder 3 rotatably connected to the inner side of the head 2, allowing the lamp holder 3 to rotate within the head 2, a white light plate 4 fixedly connected to the top of the lamp holder 3 for emitting white light for illumination, and a laser light plate 5 rotatably connected to the bottom of the lamp holder 3, with the top of the laser light plate 5 penetrating the lamp holder 3, and an LED bead in the laser light plate 5. The LED beads pass through the lamp holder 3 and are level with the white light panel 4. A convex lens 6 is slidably connected to the upper inner side of the head 2. By sliding and adjusting the distance from the light panel, the telescopic zoom and high / low beam adjustment can be achieved. A head cover 7 is threadedly connected to the top inner side of the head 2, which serves to protect the internal components and affect the light emission effect. A power supply compartment 8 is threadedly connected to the bottom of the body 1, which is used to install the battery 17 to power the flashlight. A tail 9 is threadedly connected to the bottom of the power supply compartment 8, which can both stabilize the power supply compartment 8 and make it convenient for the user to hold.
[0028] Specifically, when using this laser flashlight, the head 2, which is rotatably connected to the top of the body 1, can rotate relative to the body 1, providing convenience for adjusting the beam direction. The lamp holder 3 is rotatably connected to the head 2, and the white light panel 4, which is fixedly connected to the top of the head, is used to emit white light. The laser light panel 5, which is rotatably connected to the bottom and passes through the lamp holder 3 at the top, is used to emit laser light. When it is necessary to switch between white light and laser light, the lamp holder 3 can be rotated. By pushing or pulling the head 2, the distance between the convex lens 6 and the light panel can be changed. When the convex lens 6 is close to the light panel, the beam divergence angle increases, achieving near beam adjustment. The illumination range is wide, but the light intensity is relatively weak. When the convex lens 6 is far away from the light panel, the beam focusing effect is enhanced, realizing telescopic zoom and using the same lens to adjust the distance of the white light and green laser directional light.
[0029] Reference Figure 1 and Figure 3 A switch 10 is fixedly connected to the rear side of the flashlight body 1 to control the opening and closing of the white light panel 4 and the laser light panel 5. The switch 10 is electrically connected to the white light panel 4 and the laser light panel 5 respectively, and the power is transmitted to control the light panels to emit light. A fixing plate 11 is fixedly connected to the lower inner side of the flashlight body 1 to provide a mounting support position for other components. A charging interface 12 is fixedly connected to the top front side of the fixing plate 11 to connect to an external power source to charge the battery 17 in the power supply compartment 8. A groove 13 is provided on the front side of the flashlight body 1 to provide a locking position for the dust cover 14. A dust cover 14 is rotatably connected to the lower front side of the flashlight body 1, which can rotatably cover the groove 13. The dust cover 14 locks into the groove 13 to prevent dust and debris from entering the flashlight.
[0030] Specifically, by operating the switch 10, the user can choose to use a white light for illumination or switch to a laser light. The charging port 12, which is fixedly connected to the top front of the mounting plate 11, can be connected to an external power source to charge the battery 17 in the power supply compartment 8. When the dust cover 14 engages with the groove 13, it can effectively prevent dust and debris from entering the flashlight.
[0031] Reference Figure 1 and Figure 4 A negative electrode ring 15 is fixedly connected to the top of the fixing plate 11 for connecting with the negative electrode of the battery 17 to form a circuit loop. A positive electrode ring 16 is fixedly connected to the bottom inner side of the tail 9 for connecting with the positive electrode of the battery 17 to ensure that the current flows from the positive electrode to the negative electrode to power the flashlight. The battery 17 is slidably connected to the inner side of the power supply compartment 8 as an energy storage unit to provide power to the white light panel 4 and the laser light panel 5. Multiple luminous silicone 18s are fixedly connected at equal intervals to the outer wall of the flashlight head 2, which emit a faint light in the dark environment to facilitate the user to quickly locate the flashlight. The outer wall of the luminous silicone 18 is designed with a smooth shape to increase the user's grip comfort and avoid scratching the hands. The top of the convex lens 6 fits into the bottom of the head cover 7, which supports the head cover 7 and ensures the stable position of the convex lens 6. The size of the convex lens 6 matches that of the head cover 7 to prevent dust or debris from entering the gap between them and affecting the light adjustment effect.
[0032] Specifically, together they provide the correct electrode connection position for the installation of battery 17 in power supply compartment 8. In low light environment, luminous silicone 18 can emit a faint light, making it easy for users to quickly find the flashlight position. The smooth outer wall design increases the comfort of the user when holding the flashlight head 2. The head cover 7 can limit and protect the convex lens 6, preventing the convex lens 6 from being displaced or damaged by collision during the use of the flashlight.
[0033] Working principle: When using this laser flashlight, the head 2, which is rotatably connected to the top of the body 1, can rotate relative to the body 1, providing convenience for adjusting the beam direction. The lamp holder 3 is rotatably connected to the head 2, and the white light plate 4, which is fixedly connected to the top of the head, is used to emit white light. The laser light plate 5, which is rotatably connected to the bottom and passes through the lamp holder 3 at the top, is used to emit laser light. When it is necessary to switch between white light and laser light, the lamp holder 3 can be rotated. By pushing or pulling the head 2, the distance between the convex lens 6 and the light plate can be changed. When the convex lens 6 is close to the light plate, the beam divergence angle increases, achieving near beam adjustment. The illumination range is wide, but the light intensity is relatively weak. When the convex lens 6 is away from the light plate, the beam focusing effect is enhanced, achieving far beam adjustment. The light can be directed to a farther distance and the brightness is higher. The head cover 7, which is threadedly connected to the top of the head 2, protects the internal components. The power supply compartment 8, which is threadedly connected to the bottom of the body 1, is used to install the battery 17, providing power to the entire flashlight.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
