Abstract

Disclosed is an electric torch of which a housing (1) comprises a torch head (11) and a torch body (12), wherein a power source is provided in the torch body (12) and is electrically connected to a light-emitting element (16), and an installation hole (14) is opened in the torch body (12). The electric torch further comprises a dimming mechanism, which comprises a rotary knob (2), a rotary member (7) rotating therewith, a first switch (8), and a circuit board (10). The rotary knob (2) comprises a rotary head (21) and a rotary rod (22), wherein the rotary rod (22) penetrates the installation hole (14) and extends into the torch body (12); a surface of a main body of the rotary member (7) is provided with a groove, and the main body of the rotary member (7) is fastened to one end of the rotary rod (22) of the rotary knob (2); the first switch (8) is electrically connected to the circuit board (10), the first switch (8) has a switching handle (81), the switching handle (81) is located in the groove of the surface of the main body of the rotary member (7), and the switching handle (81) is able to perform a switching action under an acting force applied by the rotating rotary member (7); and the circuit board (10) is electrically connected to the power source and the light-emitting element (16), and the circuit board (10) controls the level of current input by the power source into the light-emitting element (16) according to the switching action of the switching handle (81) of the first switch (8). The electric torch can dim conveniently and rapidly.

Description

technical field [0001] The invention relates to a flashlight, in particular to a flashlight that can be easily dimmed. Background technique [0002] The current common flashlight can only simply control the on or off of the light-emitting element in terms of function. In the application process, people often hope that the brightness of the flashlight can be easily adjusted with the change of the lighting environment. The existing dimmable flashlights are usually dimmed by buttons or magnetic rings, and the button dimming operation is less intuitive, and the shifting is not fast enough. The magnetic ring dimming structure is complicated and the cost is high. Therefore, it is very necessary to provide a flashlight that can be easily dimmed and has a low cost. SUMMARY OF THE INVENTION [0003] In order to overcome the above deficiencies, the purpose of the present invention is to provide a flashlight that can be easily dimmed. [0004] In order to achieve its purpose, the...
