[0020] The heat dissipation assembly 7 comprises a positioning rod 75 fixedly installed inside the lens fixing frame 8, a plurality of spring pins 76 arranged inside the positioning rod 75, a heat dissipation base plate 73 slidingly connected to the outside of the positioning rod 75, heat dissipation fins 74 fixedly installed at the bottom of the heat dissipation base plate 73, and a light bar 72 fixedly installed at the top of the heat dissipation base plate 73. The light bar 72 is slidingly connected to the positioning rod 75 through a sliding hole arranged inside the light bar 72, and is slidingly connected to the heat dissipation base plate 73 through the spring pins 76 arranged inside the light bar 72. The positioning rod 75 is fixedly connected to the light bar 72 and the heat dissipation base plate 73 through the spring pins 76. A heat-conducting silica gel pad 71 is fixedly installed at the outside of the light bar 72, and the heat-conducting silica gel pad 71 is in contact with the inner wall of the lens fixing frame 8. The light bar 72 generates heat during operation, and the heat is transferred to the lens fixing frame 8 through the heat-conducting silica gel pad 71. Meanwhile, the light bar 72 is installed on the heat dissipation base plate 73, and the heat is conducted to the heat dissipation base plate 73. The heat dissipation fins 74 increase the heat dissipation area and accelerate the dissipation of heat to the surrounding air.

[0021] The waterproof and dustproof assembly 5 comprises a first sealing ring 52 fixedly installed in the air outlet 9 arranged inside the turntable fixing frame 4, a first waterproof and breathable film 51 fixedly installed on the inner wall of the first sealing ring 52, an impeller 53 fixedly installed in the air inlet 2 arranged inside the turntable fixing frame 4, a scraping rod 54 fixedly installed at one end of the impeller 53, a filter screen 57 fixedly installed in the air inlet 2 arranged inside the turntable fixing frame 4, the scraping rod 54 penetrating through the filter screen 57 and being in contact with one end of the filter screen 57, a second sealing ring 55 fixedly installed in the air inlet 2 arranged inside the turntable fixing frame 4, a second waterproof and breathable film 56 fixedly installed on the inner wall of the second sealing ring 55, and another second sealing ring 55 fixedly installed on the inner wall of the second waterproof and breathable film 56. The scraping rod 54 is rotatably connected to the inside of the other second sealing ring 55. At the air outlet 9 arranged inside the turntable fixing frame 4, the first waterproof and breathable film 51 cooperates with the first sealing ring 52, and the first sealing ring 52 plays a sealing role to prevent water and dust from entering from the air outlet 9. The first waterproof and breathable film 51 allows hot air to be discharged while preventing water and dust from entering. At the air inlet 2, if the airflow enters at a high flow rate, the airflow blows the impeller 53 fan blades and drives the impeller 53 to rotate. The operation of the impeller 53 promotes the inflow of air. The filter screen 57 preliminarily filters large-particle dust. The scraping rod 54 rotates under the drive of the impeller 53, and can scrape off the dust adhered to the surface of the filter screen 57, thereby maintaining the filtering effect of the filter screen 57. The second waterproof and breathable film 56 cooperates with the second sealing rings 55 on both sides to work. The second sealing ring 55 ensures sealing, and the second waterproof and breathable film 56 allows air to enter while blocking water and dust.

[0022] When the flashlight is used for a long time, the light bar 72 generates a large amount of heat, and a large amount of heat is transferred from the light bar 72 to the heat dissipation base plate 73, and then to the heat dissipation fins 74, thereby increasing the heat dissipation area and making the heat dissipate to the surrounding air more quickly. External cold air is transported into the lens holder 8 through the air inlet 2 of the flashlight shell 1, the rotating disc holder 4 and the lens holder 8, thereby dissipating heat to the inside of the heat dissipation fins 74, the heat dissipation base plate 73 and the lens holder 8, improving the heat dissipation efficiency. The second waterproof and breathable film 56 and the first waterproof and breathable film 51 are provided because the film has a special microporous structure with a very small pore size, which can prevent water droplets and dust particles from entering the inside of the light bar 72, while allowing air to pass freely, thereby achieving the functions of heat dissipation and waterproofing. The heat-conducting silicone pad 71 is provided to not only protect the light bar 72, but also conduct part of the heat to the lens holder 8, thereby further improving the heat dissipation function of the flashlight.
