Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-powered flashlight technology, and in particular relates to a high-powered flashlight with an explosion-proof structure. Background Technology
[0002] High-intensity flashlights are high-brightness lighting tools that use LED or HID xenon as light sources. In the security field, they are mainly used for nighttime patrols, emergency response, and other scenarios. They feature high brightness with large lumens and ultra-long range. They adopt a tactical dual-tail button design and support a one-button strobe function, which can instantly blind the target and create favorable conditions for law enforcement.
[0003] Chinese patent application CN214948326U discloses a high-powered flashlight with an explosion-proof structure. The flashlight includes a threaded groove at its left end and an explosion-proof rod at the same end. A threaded rod is fixedly connected to the right end of the explosion-proof rod. A first groove is formed at the left end of the explosion-proof rod. First sliders are symmetrically fixed to the left sides of the upper and lower walls of the inner cavity of the first groove. A first slot is formed on the right side of the inner cavity of the first groove. A fixing rod is provided in the middle of the first groove. This high-powered flashlight with an explosion-proof structure allows for easy connection between the explosion-proof rod and the flashlight through the cooperation of the threaded rod and the threaded groove, making it easy to carry. The cooperation of the first groove, the first slider, the first slot, the fixing rod, the positioning rod, and the first slot allows the fixing rod to be retracted, facilitating carrying and reducing its volume during storage.
[0004] Although the patent uses an explosion-proof rod and threaded connection to fix the high-powered flashlight, and the fixing rod can be retracted to reduce the size and make it easier to carry, the patent does not have a rapid cooling function. When the high-powered flashlight is continuously on or in strobe mode, its internal circuitry is prone to generating a lot of heat due to high power operation. If this heat cannot be dissipated in time, the flashlight may work at a high temperature for a long time, which may cause the internal circuit board components to explode and be damaged, reducing the lifespan of the flashlight and making it unusable.
[0005] To address this issue, we provide a high-powered flashlight with an explosion-proof structure. Utility Model Content

[0014] The present invention is further configured such that the inner wall of the positioning sleeve is provided with a threaded hole for use with the screw, and the right side of the elastic clip is provided with a groove for use with the finger. The threaded hole can cooperate with the screw to control the use position of the fixing frame, and the groove can make the elastic clip fit the user's finger, increasing the grip stability.
[0015] The present invention has the following beneficial effects.
[0016] 1. This utility model utilizes a rapid cooling component and a rotating sleeve to adjust the opening and closing of the heat dissipation openings. When the high-power flashlight is running at high power, rotating the sleeve aligns the two heat dissipation openings. Then, the exhaust fan is activated, drawing in external air through the air inlet. After being filtered by the filter screen, the air enters the circulation shell, where a partition guides the airflow towards the control board inside the shell. The high-speed airflow carries away the heat generated by the electronic components, and the hot air is discharged through the heat dissipation openings, achieving forced convection cooling, rapidly reducing the internal temperature, and preventing overheating that could lead to circuit board explosion and damage. The locking ring engages with the positioning teeth under the action of a spring, thus fixing the position of the rotating sleeve and preventing accidental rotation from affecting heat dissipation. This solves the explosion hazard caused by heat accumulation during continuous operation of the high-power flashlight, improving equipment safety and service life.
[0017] 2. This utility model uses an anti-slip mechanism to connect the battery compartment with a fixed frame. The user places their fingers into the fixed frame and then rotates the screw. The groove of the elastic clip fits the surface of the finger, generating a uniform clamping force to prevent the flashlight from slipping during operation. The knob makes it easy to adjust the tightness of the screw to accommodate different hand shapes, preventing the flashlight from falling due to accidental slippage, enhancing the overall explosion-proof performance, and improving the practicality and safety of high-intensity flashlights in security scenarios.

Limiting rings are fixedly connected to the top and bottom of the surface of the equipment shell 2. Annular grooves that cooperate with the limiting rings are opened at the top and bottom of the inner cavity of the rotating sleeve 61. A rubber sealing sleeve 9 is fitted onto the bottom of the surface of the circulation shell 4. An anti-slip ring is fixedly connected to the bottom of the surface of the rotating sleeve 61. The surface of the anti-slip ring has anti-slip texture. An anti-drop mechanism 10 is provided on the left side of the battery compartment 5. The anti-drop mechanism 10 includes a fixing frame 101.

[0025] Specifically: the air inlet 7 allows external air to enter the circulation housing 4; the filter screen 8 filters dust and impurities from the air, preventing them from entering the equipment housing 2; the limiting ring and annular groove limit the rotation of the rotating sleeve 61, allowing it to rotate smoothly and preventing it from detaching from the surface of the equipment housing 2; the rubber sealing sleeve 9 blocks and seals the air inlet 7 on the surface of the circulation housing 4, preventing external dust and moisture from entering the circulation housing 4 when heat dissipation is not required; the anti-slip ring allows the user to easily rotate the rotating sleeve 61; and the fixing bracket 101 can...

The exhaust fan 68 starts, drawing external air into the circulating air duct. After being filtered by the filter screen 8, the air is blown upwards towards the control main board 3 inside the device housing 2 under the guidance of the partition 67. The high-speed airflow quickly carries away the heat generated by the electronic components on the control main board 3 during operation. The heated air is then discharged through the aligned heat dissipation opening 62, achieving forced convection cooling, thereby rapidly reducing the internal temperature of the flashlight and preventing damage to the electronic components due to overheating. Once the heat dissipation opening 62 is in place, the locking ring 66... Under the elastic force of the spring 65, it moves upward and engages with the positioning teeth 63 at the bottom of the rotating sleeve 61, fixing the position of the rotating sleeve 61 and preventing accidental rotation during use. When heat dissipation is not required, the rotating sleeve 61 is rotated in the opposite direction to offset the heat dissipation opening 62. At the same time, the rubber sealing sleeve 9 blocks the air inlet 7 to prevent dust and moisture from entering. In addition, when the user holds the battery compartment 5, he can put his fingers into the fixing bracket 101 and then rotate the screw 103. The screw 103 screws into the threaded hole of the positioning sleeve 104, pushing the fixing bracket 101 towards the battery compartment 5, so that the groove on the elastic clip 102 fits against the back of the finger, forming a stable clamp, thereby preventing the flashlight from accidentally slipping out of the hand during operation and enhancing the safety of holding it.
