Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and in particular to a multifunctional flashlight. Background Technology

[0002] In modern society, with the increasing diversification of people's lifestyles and the widespread development of various outdoor and specialized work activities, the demand for portable lighting equipment is showing a rapid growth trend. Outdoor activities, such as hiking, mountaineering, and camping, have become important ways for many people to relax and get close to nature. In camping and adventure activities, reliable lighting tools are indispensable for setting up tents, cooking food, and exploring the surrounding environment at night. In the field of night work, including power maintenance, road construction, and security patrols, there is an urgent need for equipment that can adapt to complex environments and provide efficient lighting.

[0003] However, traditional flashlights widely used in the market are increasingly revealing their significant limitation in functionality when facing these diverse usage scenarios. From a light source design perspective, most existing flashlights employ a single light source mode. Some flashlights focus on long-range illumination, typically equipped with high-brightness, highly focused light sources that can concentrate light over considerable distances. This is useful when long-distance observation is required, such as finding distant landmarks during outdoor activities or inspecting distant equipment during nighttime operations. However, they are clearly deficient in close-range lighting and creating atmosphere. For example, when camping, they cannot provide soft, even light to illuminate the entire campsite and create a comfortable and relaxing atmosphere.

[0004] Another type of flashlight uses a floodlight design, with a wide beam dispersion range, providing relatively uniform illumination within a certain area. It is suitable for close-range, large-area lighting needs, such as daily activities inside a tent or providing general lighting for a localized area at a nighttime work site. However, this type of flashlight has weak long-range capabilities, and often cannot meet the requirements when illuminating distant targets, such as spotting distant hazards during outdoor activities or checking the status of distant equipment during nighttime work.

[0005] This type of flashlight, with its single light source design, has functional limitations and cannot simultaneously meet the needs of long-distance illumination and creating a specific atmosphere. For example, when camping or exploring, users may need a flashlight that can illuminate potentially dangerous areas in the distance (such as wildlife habitats) while also providing warm, inviting lighting for the campsite, but traditional flashlights clearly cannot meet this requirement. Users are forced to carry multiple lighting devices, which not only increases their travel burden but also causes numerous inconveniences during use, such as frequently changing devices and managing multiple lighting fixtures.

[0006] In conclusion, the limited functionality of traditional flashlights, coupled with their increasingly diverse applications, has become a key factor hindering their further development. Therefore, developing a multi-functional flashlight that can simultaneously provide long-distance illumination and enhance the desired atmosphere is of significant practical importance and market value.

[0034] See Figures 1 to 5 As shown in the specific embodiment, this utility model discloses a multifunctional flashlight, including: a body 10, a PCBA board 20, a substrate 30, and a battery 40. The substrate 30, the PCBA board 20, and the battery 40 are installed on the body 10 from front to back, and the substrate 30 and the battery 40 are electrically connected to the PCBA board 20. A main LED bead 31 is provided at the center of the substrate 30, RGB colored lights 32 are provided around the main LED bead 31, and ambient light beads 33 are provided around the RGB colored lights 32.

[0035] Specifically, a suitable material for the flashlight body 10, with appropriate length, diameter, and strength, is selected. A common material is aluminum alloy, which is lightweight, high-strength, and has good heat dissipation. The body 10 is processed according to design requirements, including creating holes at the front end for mounting the substrate 30 and setting corresponding slots or fixing structures inside the body 10 to facilitate the subsequent installation of the PCBA board 20 and battery component 40. The battery component 40, such as a lithium battery pack, is inserted into the rear end of the body 10 with the correct polarity. The battery component 40 is electrically connected to the PCBA board 20 via wires or springs, providing power to the entire flashlight. The PCBA board 20 is placed inside the body 10 in the predetermined direction and position, and secured using the slots or screws inside the body 10. The PCBA board 20 integrates various electronic components and circuits for controlling the flashlight's light switch, brightness adjustment, color switching, and other functions. The substrate 30 is precisely installed in the pre-set holes at the front end of the body 10, using threaded connections, snap-fit ​​fixings, or other methods to ensure a secure and accurate installation. The substrate 30 is usually round or square, and its material must have good electrical conductivity and heat dissipation.

[0036] A main LED bead 31 is installed at the center of the substrate 30. The main LED bead 31 typically uses a high-brightness, high-efficiency LED, and its power and brightness can be selected according to actual needs. The main LED bead 31 is connected to the circuitry on the substrate 30 via soldering or plug-in connection, ensuring stable current transmission to the main LED bead 31. RGB LEDs 32 are evenly distributed around the main LED bead 31. The RGB LEDs 32 consist of red, green, and blue LEDs, and various color changes can be achieved by adjusting the brightness ratio of the three colors. The RGB LEDs 32 are also connected to the substrate 30 via soldering or plug-in connection and are connected to the control circuitry of the PCBA board 20. Ambient LEDs 33 are installed around the RGB LEDs 32. The ambient LEDs 33 can use warm white or other colored LEDs, providing softer light for creating ambient lighting effects. The installation and connection methods of the ambient LEDs 33 are similar to those of the main LED bead 31 and the RGB LEDs 32, ensuring their proper functioning.

[0037] In other words, the main LED bead 31 is located at the center of the substrate 30, enabling it to emit high-brightness light for long-distance illumination. In outdoor adventures, night patrols, and other scenarios, users can clearly illuminate distant targets, such as roads, buildings, or potentially dangerous areas, providing safety for their actions. For example, when hiking in mountainous areas at night, the long-range beam of the main LED bead 31 can help users spot obstacles or wild animals ahead, preventing accidents. The inclusion of RGB colored lights 32 and ambient LED beads 33 gives the flashlight ambient lighting functionality. The RGB colored lights 32 can create different atmospheric effects by adjusting color and brightness, such as romantic red, cheerful yellow, mysterious blue, or a marquee effect, suitable for leisure activities like parties and camping. The ambient LED beads 33 provide soft, even light, adding a warm atmosphere to the surrounding environment, making users more comfortable and relaxed during nighttime activities. Furthermore, the substrate 30, PCBA board 20, and battery 40 are sequentially installed inside the body 10 from front to back. This compact design makes the flashlight small in size and space-saving.

[0038] See Figure 2 and Figure 5 As shown, in one embodiment, the area of ​​the main lamp bead 31 is further provided with a lamp cup 50, and the main lamp bead 31 extends into the inner side of the lamp cup 50.

[0039] Specifically, the reflector 50 is typically made of a metal with high reflectivity, such as aluminum alloy. Aluminum alloy is not only lightweight, facilitating the design and assembly of the flashlight's overall structure, but its surface, after special treatment (such as anodizing), can achieve a reflectivity of over 90%, effectively reflecting the light emitted by the main LED 31 and reducing light loss. The reflector 50 is generally designed in a parabolic shape or a similar curved surface. This shape is based on optical principles; the parabolic surface can focus the light from the focal point (i.e., the location of the main LED 31).

[0040] In other words, the light emitted by the main LED 31 is focused by the reflector 50 before being emitted. The parabolic surface of the reflector 50 concentrates the originally divergent light, forming a narrow and bright beam. This focusing effect allows the flashlight to travel further when illuminating at a distance, greatly increasing the beam's range. For example, without the reflector 50, the light emitted by the main LED 31 is relatively dispersed, and its intensity rapidly decreases at greater distances. However, with the reflector 50 installed, the light is focused, and at the same distance, the light intensity is significantly enhanced, illuminating targets further away. Due to the focused light, the intensity is significantly increased in the central region of the beam. This allows the flashlight to provide a clearer and brighter field of vision in scenarios requiring high-brightness illumination, such as nighttime searches and outdoor adventures, helping users better observe their surroundings and improving safety and work efficiency. In addition, the focusing effect of the reflector 50 not only increases the beam's range and brightness but also makes the emitted light spot more uniform. When illuminating at a distance, the light spot has a clear edge, high brightness in the central area, and a natural transition, avoiding the problems of blurred light spots and uneven brightness caused by light dispersion. A uniform light spot allows users to more accurately determine the location and characteristics of targets, improving the practicality and accuracy of the illumination. The lamp reflector 50 effectively confines the light emitted by the main LED 31 to a specific direction, reducing stray light. Stray light not only wastes energy but also causes light pollution to the surrounding environment, affecting the user's vision and the normal activities of others. Through the focusing effect of the lamp reflector 50, the light emitted by the flashlight is more concentrated, reducing unnecessary stray light and making the lighting effect more focused and efficient.

[0041] In one embodiment, the RGB colored light 32 is located outside the lamp cup 50, and the outside of the lamp cup 50 is provided with a reflective layer.

[0042] Specifically, the reflective layer is typically made of materials with high reflectivity, such as thin films of metals like silver or aluminum, or uses special reflective coatings. Metal films can be uniformly adhered to the outer surface of the lamp cup 50 through processes such as vacuum coating, achieving a reflectivity of over 95%, effectively reflecting light. Reflective coatings, on the other hand, offer advantages such as ease of application and lower cost. They can form a uniform reflective coating on the outer surface of the lamp cup 50, also achieving a high reflectivity.

[0043] In other words, the reflective layer on the outer side of the lamp cup 50 effectively reflects the light emitted by the RGB colored lights 32 and the ambient light beads 33, reducing light absorption and scattering. Light that might otherwise be wasted due to dispersion is reflected by the reflective layer and directed more in a specific direction, thus improving light utilization and providing brighter, more uniform light for close-range illumination. Through the reflective effect of the reflective layer, the light emitted by the RGB colored lights 32 and the ambient light beads 33 can cover the surrounding environment more broadly, expanding the illumination range. At the same time, the reflective layer makes the light distribution more uniform, avoiding areas that are too bright or too dark, creating a more comfortable and natural lighting atmosphere. For example, in a camping setting, the light reflected by the reflective layer can evenly illuminate the entire campsite, providing a good environment for activities. Furthermore, the RGB colored lights 32 themselves have multiple color-changing capabilities, and the reflective effect of the reflective layer makes these colors more vibrant and saturated. When the RGB LEDs 32 emit different colors of light, the reflective layer evenly reflects the light, making the colors more vivid and realistic, and enhancing the flashlight's color performance. For example, in a party setting, the vibrant colors reflected by the reflective layer from the RGB LEDs 32 can create a cheerful and lively atmosphere. The light emitted by the ambient LEDs 33, after being reflected by the reflective layer, can also blend better into the overall lighting effect. Users can adjust the color, brightness, and flashing frequency of the RGB LEDs 32 and ambient LEDs 33 through the control circuit to achieve diverse atmosphere effects according to different scenarios and needs. Whether it's a warm and romantic candlelight dinner atmosphere or a mysterious and fantastical adventure atmosphere, this flashlight can easily achieve both.

[0044] See Figures 1 to 4 As shown, in one embodiment, the cylindrical body 10 is provided with a light guide cover 60 on the outside of the lamp cup 50, and the light emitted by the RGB colored light 32 or the ambient light bead 33 is reflected by the reflective layer and then emitted by the light guide cover 60.

[0045] Specifically, the light guide 60 is typically made of materials with good optical properties and light transmittance, such as polycarbonate (PC) and acrylic (PMMA). These materials have high transparency, allowing light to pass through smoothly, while also possessing good heat resistance, impact resistance, and weather resistance, making them suitable for use in various environments. The shape of the light guide 60 is designed according to the overall appearance of the flashlight and its lighting requirements. Common shapes include cylindrical and conical. A cylindrical light guide 60 can evenly scatter light in all directions, suitable for scenarios requiring uniform illumination over a large area; a conical light guide 60 can converge and guide light, making it more concentrated in a specific direction. The inner wall of the light guide 60 is usually designed with a smooth curved surface to reduce light reflection loss. The light guide 60 is installed on the body 10 at the corresponding position outside the lamp cup 50, ensuring that the light guide 60 completely covers the emission area of ​​the light emitted by the RGB colored light 32 or ambient light bead 33 after reflection by the reflective layer. The light guide cover 60 can be fixed to the cylinder body 10 by means of snap-fit, threaded connection, or adhesive bonding. Snap-fit ​​fixing is convenient for installation and easy to disassemble and replace the light guide cover 60; threaded connection is more secure and can ensure that the light guide cover 60 will not loosen during long-term use; adhesive bonding is suitable for some occasions with high sealing requirements, but it may be more difficult to disassemble.

[0046] In other words, the light guide 60 redistributes the light emitted by the RGB LEDs 32 or ambient LEDs 33 after reflection through the reflective layer, allowing the light to be scattered more evenly. This avoids the light concentrating in a small area, resulting in localized overbrightness and surrounding darkness, thus providing a more comfortable and natural lighting effect. For example, when using a flashlight as ambient lighting indoors, the light guide 60 can evenly illuminate the entire room, creating a warm and soft atmosphere. Furthermore, for the RGB LEDs 32, the light guide 60 allows for more even mixing and scattering of different colors, enhancing color saturation and vibrancy. When the RGB LEDs 32 emit colorful light, the light guide 60 can perfectly display these colors, creating a richer and more vibrant visual effect, suitable for parties, performances, and other occasions requiring a strong visual impact. The surface treatment and shape design of the light guide 60 can create various unique light and shadow effects. For example, a light guide 60 with optical textures can produce effects such as flickering and gradation, increasing the fun and artistry of the lighting. When camping outdoors, this unique light and shadow effect can add a romantic and mysterious atmosphere to nighttime activities. In addition, the light guide cover 60 provides a layer of physical protection for optical components such as RGB colored lights 32 and ambient light beads 33, preventing them from being damaged by external impacts, scratches, dust, and moisture, thus extending the lifespan of the optical components and improving the reliability and stability of the flashlight.

[0047] See Figures 1 to 4 As shown, in one embodiment, the front end of the light guide cover 60 is further provided with an end cap 70; a coated tempered glass 80 is further provided between the end cap 70 and the lamp cup 50.

[0048] Specifically, the end cap 70 is typically made of high-strength, corrosion-resistant metal materials, such as aluminum alloy or stainless steel. Aluminum alloy is lightweight, facilitating the lightweight design of the flashlight's overall structure, and has good heat dissipation performance; stainless steel has higher strength and corrosion resistance, making it suitable for scenarios with high environmental adaptability requirements. Tempered glass with high light transmittance and good mechanical properties is selected as the base material. Tempered glass undergoes a special heat treatment process, resulting in high strength and impact resistance, effectively preventing breakage due to collisions during use. Simultaneously, its light transmittance should be as high as possible to reduce light loss, generally requiring a transmittance of over 90%. A coating treatment is applied to the surface of the tempered glass; the coating material can be selected according to actual needs. Common coatings include anti-reflective coatings and anti-reflective coatings. Anti-reflective coatings reduce light reflection loss on the glass surface, increasing light transmittance; anti-reflective coatings further reduce reflectivity, allowing light to pass through the glass more evenly. The coating process typically employs vacuum coating technology, where the coating material is evaporated and deposited onto the glass surface in a vacuum environment, forming a uniform thin film. The pre-processed coated tempered glass 80 is placed into the pre-reserved installation space of the end cap 70 and secured firmly using a locking mechanism such as a slot or thread. The end cap 70 with the coated tempered glass 80 installed is then assembled with the light guide cover 60. Threaded connections or snap-fit ​​connections can be used to ensure the end cap 70 is tightly fixed to the front end of the light guide cover 60.

[0049] In other words, the anti-reflective and anti-reflective coatings on the surface of the coated tempered glass 80 effectively reduce light reflection loss on the glass surface, allowing more light to pass through. Compared to uncoated glass, coated tempered glass significantly improves light transmittance, thereby enhancing the brightness and effect of the flashlight. The coated tempered glass 80 makes the light passing through it more uniform and softer, reducing light scattering and color difference. This helps improve the lighting quality of the flashlight, making the colors of illuminated objects more realistic and natural, providing users with a better visual experience. In addition, the end cap 70 and the coated tempered glass 80 together form a protective barrier, effectively protecting the lamp cup 50 from external impacts, scratches, and corrosion from dust and moisture.

[0050] See Figure 2 As shown, in one embodiment, the tail end of the cylinder 10 is also provided with a connection port 11.

[0051] Specifically, the connector 11 is typically designed as a standard threaded interface, such as the common 1 / 4-inch-20UNC thread specification. This is a widely used interface standard for photographic equipment and tripods, ensuring good compatibility between the flashlight and various external structures. Align the connector 11 at the tail end of the flashlight body 10 with the corresponding threaded interface on the tripod head, and then rotate the flashlight clockwise to secure it to the tripod. After connection, the flashlight can be fixed in a suitable position and orientation to meet different lighting needs by adjusting the height and angle of the tripod and the rotation angle of the tripod head. In addition to tripods, the connector 11 can also be connected to other external structures with corresponding threaded interfaces, such as extension rods and mounting brackets. The connection method is similar to connecting a tripod; simply align the connector 11 of the flashlight with the interface of the external structure and tighten it. For example, in disaster relief scenarios, the flashlight can be connected to an extension rod to provide illumination for rescuers at heights or in confined spaces.

[0052] In other words, in photography scenarios, the flashlight is mounted on a tripod via connector 11, and its angle and brightness are adjusted according to shooting needs. The color, brightness, and flashing frequency of the RGB LEDs 32 and ambient LEDs 33 can be adjusted via the flashlight's control circuit to achieve different fill light effects. During long exposure shooting, the flashlight is set to a stable lighting mode to ensure continuous and uniform light throughout the exposure time for ideal shooting results. At disaster relief sites, the flashlight is connected to a fixed bracket or extension pole and placed in a suitable location to provide large-area illumination for rescuers. The flashlight's high brightness mode and long-range beam function can be used to illuminate the rescue area, helping rescuers quickly locate trapped individuals and obstacles. Simultaneously, the RGB LEDs 32 can emit different colored signal lights for communication and instruction with other rescuers. During power outages, the flashlight is mounted on a tripod or wall bracket for use as a fixed lighting device. An appropriate brightness mode is selected to meet the lighting needs of indoor activities. Since the flashlight can be stably fixed to a bracket via connector 11, it does not need to be held by hand, facilitating various activities during power outages.

[0053] See Figures 1 to 3 As shown, in one embodiment, the cylinder body 10 is provided with a control switch 90, which is electrically connected to the PCBA board 20.

[0054] Specifically, common control switches include tactile switches, latching switches, touch switches, and rotary switches. Tactile switches switch the circuit on and off with a brief press, offering sensitive operation and are suitable for scenarios requiring frequent switching of light states, such as switching between different brightness modes (low, medium, and high) of a flashlight. Latching switches hold the state after being pressed and return to their original state only when pressed again, and can be used to turn the flashlight's basic lighting function on or off. Touch switches utilize the principle of human body capacitance sensing; when a finger touches the switch surface, the circuit is connected or disconnected. Touch switches have a simple appearance, no wear and tear on mechanical parts, a long service life, and can achieve some intelligent control functions, such as switching light colors with a long press (for flashlights with RGB color lighting). Rotary switches adjust circuit parameters by rotating the knob, such as adjusting the brightness or color of the light. Rotary switches provide a continuous adjustment range, allowing users to precisely control the lighting effect according to their actual needs.

[0055] In other words, users can quickly turn the flashlight on or off and switch between different lighting modes using the control switch 90. For example, in a dark environment where emergency lighting is needed, simply pressing the switch provides immediate light, making operation simple and quick. For flashlights with multiple functions, such as the RGB color light 32 flashlight with adjustable brightness and color, users can personalize the lighting according to their needs using the control switch 90. For instance, when taking photos, the flashlight's light color can be adjusted according to the atmosphere of the shooting scene to meet different creative needs. Furthermore, through the circuit design of the PCBA board 20 and the coordination of the control switch 90, the flashlight can achieve multiple lighting modes, such as constant light mode, flashing mode, and SOS distress mode. These modes can be switched using different switch operation methods, providing users with more choices.

[0056] See Figures 1 to 3 As shown, in one embodiment, the cylinder body 10 is further provided with a Hall effect switch 100, which is electrically connected to the PCBA board 20.

[0057] Specifically, select the appropriate Hall effect switch 100 type based on the flashlight's usage scenario and functional requirements. Common types include unipolar Hall effect switches and bipolar Hall effect switches. Unipolar Hall effect switches are triggered by a single magnetic field direction, have a simple structure, and are low in cost, making them suitable for simple function switching, such as switching the brightness mode of a flashlight (switching between low and high brightness). Bipolar Hall effect switches require alternating interaction of north and south magnetic fields to be triggered, enabling more complex control logic, such as multi-level switching when the flashlight has multiple modes (brightness, color, flashing mode, etc.). Install the Hall effect switch 100 in an easily accessible location on the flashlight body 10 with good magnetic field induction. It can generally be placed on the side of the flashlight body 10, allowing the user to operate it with their fingers or magnetic tools while holding the flashlight.

[0058] In other words, the Hall effect switch 100 is a non-contact switch based on magnetic field induction, eliminating the wear and tear issues associated with mechanical contacts. Compared to traditional mechanical push-button switches, it has a longer lifespan, can withstand more operations, and reduces flashlight malfunctions caused by switch failure. The Hall effect switch 100 is less sensitive to environmental factors such as dust, moisture, and oil. Even in harsh environments, such as outdoor adventures and industrial operations, it maintains stable performance and its normal operation is not affected by environmental factors, further improving the flashlight's durability.

[0059] In one embodiment, the PCBA board 20 also integrates a voice module.

[0060] Specifically, prioritize voice modules with fast response times to enable quick wake-up and control of the flashlight. Generally, the response time of the voice module should be within a few hundred milliseconds, allowing the flashlight to react quickly after the user issues a command, thus improving the user experience. Considering the flashlight's portability and battery life, choose a low-power voice module. Some voice modules have sleep modes and wake-up mechanisms; they enter a low-power sleep state when no voice command is received, and are only awakened and begin recognizing commands when a specific wake word is detected, thereby reducing overall power consumption.

[0061] In other words, users no longer need to operate the flashlight using traditional buttons or touch controls; they can simply speak voice commands to switch and control various functions. For example, in a dark environment, users don't need to fumble for buttons on the flashlight; simply saying "turn on the flashlight" will quickly provide illumination, greatly simplifying the operation. The voice module supports multiple voice commands, enabling integrated control of multiple flashlight functions. Users can complete multiple operations with a single voice command, such as "switch to red high-brightness mode," which is more convenient and efficient compared to the traditional method of operating buttons one by one. Furthermore, in cold weather or industrial work scenarios, users may need to wear gloves, making traditional button operation difficult. Voice control, however, is unaffected by gloves; users can easily control the flashlight with voice commands even while wearing thick gloves, improving its usability in special environments. In humid environments, such as rainy outdoor conditions or underwater operations, buttons may experience poor contact due to moisture. Voice control avoids direct contact between buttons and water, ensuring stable operation in humid environments and guaranteeing normal flashlight use.

[0062] See Figure 4As shown, in one embodiment, the cylinder body 10 is further provided with a display screen 110 and a charging interface 120, both of which are electrically connected to the PCBA board 20. The display screen 110 is used to display the battery level, and the charging interface 120 is used to charge the battery 40.

[0063] Specifically, the appropriate display screen type (110) should be selected based on the flashlight's size, power consumption requirements, and display needs. Common types include segment LCD displays (110) and dot-matrix displays (110). Segment LCDs have a simple structure and low power consumption, making them suitable for displaying simple information such as battery percentage and charging status. They are also relatively inexpensive, making them suitable for cost-sensitive flashlight products. Dot-matrix displays (110) can display richer information, such as battery level numbers, icons, and simple text prompts, but they have relatively higher power consumption and cost, making them suitable for flashlights with higher display requirements. Currently, common flashlight charging interfaces (120) include USB, Type-C, and magnetic charging interfaces (120). USB interfaces are inexpensive and widely used. Type-C interfaces support reversible insertion and offer fast charging. Magnetic charging interfaces (120) offer the advantages of convenient charging and no need for precise alignment of the plug, making them suitable for special applications such as underwater flashlights.

[0064] In other words, users can intuitively understand the remaining battery power of the flashlight through the display screen 110, avoiding the situation of the flashlight suddenly going out due to insufficient power. For example, when exploring outdoors, users can reasonably plan the flashlight's usage time based on the battery power display on the display screen 110 and prepare to charge it in advance. In addition to displaying the battery power, the display screen 110 can also display charging status, fault prompts, and other information. When the flashlight is charging, the display screen 110 can display the charging progress; when the flashlight malfunctions, such as battery overheating or short circuit, the display screen 110 can display the corresponding fault code or prompt information, making it convenient for users to understand the flashlight's working status and take appropriate action. In addition, different types of charging interfaces 120 provide users with more charging options. For example, the Type-C interface supports fast charging, greatly shortening charging time; the magnetic charging interface 120 does not require precise alignment of the socket, making charging more convenient and faster. Users can choose the appropriate charging interface 120 for charging according to their needs and the type of charging device. Using universal charging interfaces 120, such as USB and Type-C interfaces, can improve the flashlight's versatility and compatibility. Users can charge the flashlight using common mobile phone chargers, power banks, and other devices, eliminating the need for a dedicated charger and reducing usage costs.

[0065] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
