The structure of the flashlight that switches the light color in this way is relatively complicated. In addition, because the lamp holder part needs to move or rotate dynamically, there will inevitably be a matching gap in the connection with the shell, resulting in the heat of the LED lamp beads cannot be transferred to the shell in time, which leads to poor heat dissipation of the flashlight and cannot achieve high brightness and high lumen; there is also a flashlight structure that combines the color lens and the small reflector cup into one as a dynamic rotating body. Although this structure can achieve good heat dissipation effect, it will produce a momentary black hole light pattern when switching the color lens, affecting the user experience.

[0019] Specifically, it also includes a screw 112, a torsion spring 113, a toggle block 114 and a rotating member 115. The rear end of the bracket 106 is respectively provided with a screw hole 1061, the screw 112 is respectively rotatably inserted into the screw hole 1061 and screwed on the outer wall of the upper end of the support seat 105, the torsion spring 113 is respectively sleeved on the upper end of the screw 113, the rear end of the bracket 106 is respectively provided with a plug hole 1062, one end of the torsion spring 113 is fixed to In the insertion hole 1062, the other end of the torsion spring 113 abuts against the inner wall of the fixing member 108, and the upper end of the support seat 105 is recessed with a plurality of slide grooves 1052 extending in the radial direction. The toggle blocks 114 are slidably embedded in the slide grooves 1052, respectively. The front end of the toggle block 114 abuts against the bracket 106, and the rear end of the toggle block 114 can extend out of the slide groove 1052. The rotating member 115 can be rotatably sleeved on the outer peripheral wall of the fixing member 108.

[0020] Specifically, the inner wall of the rotating member 115 is recessed with an open groove 1151 extending in the circumferential direction, the angle of the open groove 1151 is 270°, both ends of the open groove 1151 are arranged in an inclined surface structure, the rear end of the toggle block 114 is arranged in an arc curved surface structure, and the rear end of the adjacent toggle blocks 114 can be located on the inclined surfaces at both ends of the open groove 1151 at the same time, so that the toggle blocks are synchronous when driving the adjacent brackets to swing, that is, when the rotating member is rotated to switch the light color, one of the toggle blocks is in contact with the inner wall of the rotating member, and the other two toggle blocks are located in the open groove. When the rotating member is rotated to make one of the toggle blocks swing When the toggle block is just located on the inclined surface of the opening groove, the other toggle block adjacent to it is also just located on the inclined surfaces at both ends of the opening groove, so that one of the color lenses gradually moves away from the through hole while the other color lens synchronously approaches the through hole, until one of the color lenses is completely away from the through hole and the other color lens is completely located on the through hole, and three color lenses of different colors appear alternately above the through hole, thereby completing the rapid alternating switching of the lens colors, realizing the switching of the flashlight light colors, and avoiding the black hole phenomenon caused by the two color lenses not being switched synchronously during the color lens switching process, effectively improving the user experience.

[0021] When the rear end wall of one of the toggle blocks 114 abuts against the inner circumferential wall of the rotating member 115, the rear ends of the other two toggle blocks 114 are both located in the opening groove 1151, and the toggle blocks 114 drive the bracket 106 to swing, driving the color lenses 107 to alternately be located at the upper ends of the through holes 1051.

When the rotating member is rotated to switch the light color, the rotating member rotates into place, and the spring pins are just stuck in the limiting grooves, which makes it easy to identify whether the rotating member is rotated into place. At the same time, the rotating member can be limited to prevent it from rotating on its own.

[0022] Specifically, a plurality of arc-shaped limiting grooves 1053 are recessed at the upper end of the support seat 105, and the lower end of one end of the torsion spring 113 can slide along the arc-shaped limiting groove 1053, thereby limiting the rotation angle of the bracket to prevent it from rotating too much.

[0024] Specifically, the working principle and process of the present invention are: When the rotating part is rotated to switch the light color, one of the toggle blocks is in contact with the inner wall of the rotating part, and the other two toggle blocks are located in the open groove. When the rotating part is rotated so that one of the toggle blocks is just located on the inclined surface of the open groove, the other toggle block adjacent to it is also just located on the inclined surfaces at both ends of the open groove, so that one of the color lenses gradually moves away from the through hole while the other color lens approaches the through hole synchronously, until one of the color lenses is completely away from the through hole and the other color lens is completely located on the through hole. Three color lenses of different colors appear alternately above the through hole, thereby completing the rapid alternating switching of the lens colors and realizing the switching of the flashlight light colors. It can also avoid the black hole phenomenon caused by the two color lenses not being switched synchronously during the color lens switching process, effectively improving the user experience, and there is no gap between the LED lamp bead and the bottom of the lamp holder accommodating groove, so that the heat of the LED lamp bead can be effectively conducted to the lamp holder, thereby improving the heat dissipation effect of the flashlight.
