Abstract

The invention provides an electric torch. An electric torch shell comprises a torch head and a torch body. A power source is arranged in the torch body and electrically connected with a light emitting element. An installation hole is formed in the torch body. The electric torch further comprises a dimming mechanism. The dimming mechanism comprises a rotary knob, a rotary part rotating along with rotation of the rotary knob, a first switch, and a circuit board. The rotary knob comprises a rotary knob head and a rotary rod. The rotary rod penetrates through the installation hole to extend into the torch body. The surface of the body of the rotary part is provided with a groove. The body of the rotary part is fastened to the tail end of the rotary rod of the rotary knob. The first switch is electrically connected with the circuit board and provided with a switching handle. The switching handle is located in the groove in the surface of the body of the rotary part. The switching handle can carry out switching motion under the acting force applied by the rotating rotary part. The circuit board is electrically connected with the power source and the light emitting element. The circuit board controls the current, input into the light emitting element, of the power source according to the switching motion of the switching handle of the first switch. The electric torch can achieve dimming conveniently and rapidly.

Description

technical field [0001] The invention relates to a flashlight, in particular to a flashlight which can be adjusted easily. Background technique [0002] The current common flashlights can only simply control the on or off of the light-emitting element in terms of function. During the application process, people often hope that the brightness of the flashlight can be adjusted conveniently as the lighting environment changes. Existing dimmable flashlights are usually dimmed by buttons or magnetic rings. The button dimming operation is not intuitive, and the shifting is not fast enough. The structure of magnetic ring dimming is complicated and the cost is high. Therefore, it is very necessary to provide a flashlight that can be easily dimmed and has low cost. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the present invention is to provide a flashlight that can be easily dimmed. [0004] The present invention is for reaching...
