Description

Technical Field

[0001] This utility model belongs to the field of flashlight technology, and specifically relates to a retractable flashlight. Background Technology

[0002] Flashlights are powered by batteries, and the current is transmitted to the light source through the circuit. Traditional flashlights use incandescent bulbs, and the current heats the filament to emit light. Modern flashlights mostly use LEDs, which produce light through electroluminescence. The light is concentrated by a reflector and focused by a lens to form a bright beam. The switch controls the flashlight to turn on and off.

[0003] Chinese patent publication number "CN217235335U" discloses a flashlight. The flashlight includes a flashlight body and a diffuser. One end of the flashlight body is the head, and the diffuser is fitted onto the head of the flashlight body. The diffuser is used to soften the light emitted by the light source inside the head. When the diffuser is fitted onto the head of the flashlight body, there is an interference fit area and a gap area between the inner wall surface of the diffuser and the outer wall surface of the head.

[0004] However, this flashlight still has some shortcomings. Since the outer wall of most flashlights is a sealed integral structure, the internal ventilation and heat dissipation are mostly achieved through the small gaps at the connection points of the flashlight shell. Its heat dissipation efficiency is extremely low. If a ventilation port is added, dust or pollutants in the air will enter the flashlight and damage its internal components, thereby reducing the lifespan of the flashlight. Utility Model Content
