Description

Technical Field

[0001] The utility model relates to the technical field of flashlights, in particular to a push-out arc flashlight. Background Art

[0002] A flashlight, also known as a flashlight, is a handheld electronic lighting tool. Early flashlights only had a single lighting mode, and the light source was turned on or off by toggling a switch set on the side of the barrel. Some flashlights also turned the light source on or off by pressing a switch at the end of the barrel. Since the functions of existing flashlights are still relatively simple, they are only used in the field of lighting functions to achieve a variety of lighting functions and cannot be applied to a variety of scenarios. In response to this, the applicant provides a multifunctional flashlight (application number CN220750093U), which integrates lighting functions, disaster prevention functions, and self-defense functions, so that the flashlight is applicable to a variety of scenarios.

[0003] However, the multifunctional flashlight provided above has the following technical problems in actual use: when taking self-protection measures, since the ceramic head of the arc function provided above is hidden inside the aluminum tail cover, the aluminum tail cover needs to be opened to use the arc function, which makes it inconvenient to take self-protection measures in time. Summary of the invention

[0004] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide an arc ejection flashlight.

[0005] The utility model adopts the following technical scheme to achieve its technical purpose: an arc push-out flashlight, comprising a lamp holder, a barrel assembly and an arc assembly, wherein the lamp holder and the arc assembly are respectively fixed at two ends of the barrel assembly, the barrel assembly comprises an aluminum middle barrel, and the arc assembly comprises a zinc alloy ignition head, an arc telescopic tension spring, an ignition coil, a push plate, a ceramic head and a fixed plastic part;

[0006] The zinc alloy ignition head is fixed to one end of the aluminum middle cylinder, and the ceramic head is arranged inside the zinc alloy ignition head, and one side of the ceramic head is fixed to one end of the fixed plastic part;

[0007] One end of the fixed plastic part is fixed to the push plate, the push plate is exposed and slidably connected to the outer wall of the aluminum middle tube, and one end of the fixed plastic part is fixed to the arc telescopic spring, one end of the arc telescopic spring is fixed inside the aluminum middle tube, and the ignition coil is fixed inside the push plate;

[0008] The pushing plate is moved to overcome the force of the arc expansion spring, so that the ignition coil, the ceramic head and the fixed plastic part are moved. After the ignition coil moves, it is energized to enter the arc mode, and the ceramic head extends out of the zinc alloy ignition head to generate an arc. After the ignition coil moves, it is connected to the control PCB board. After five seconds, the control PCB board is automatically powered off, so that the arc is automatically extinguished, or the pushing plate is retracted under the return force of the arc expansion spring, and the ignition coil is not connected to the control PCB board, so that the arc is extinguished.

[0009] Preferably, an arc-shaped groove is formed on the edge of one end of the zinc alloy ignition head, and a plurality of arc-shaped grooves form a convex block, so that the flashlight has a window-breaking function through the convex block.

[0010] Preferably, a LED red and white light is fixedly installed inside the lamp holder;

[0011] The aluminum middle cylinder has a main plastic part and a plastic cover plate fixedly installed inside, and a buzzer, a control PCB board, a lithium battery fixedly installed on the control PCB board, a decorative plate and function keys fixedly installed inside the main plastic part and the plastic cover plate;

[0012] The LED red and white lights, function buttons, buzzer and lithium battery are all electrically connected to the control PCB board;

[0013] When the flashlight is off, long press the function button for 0.5 seconds to make the control PCB board enter the lighting mode. The control PCB board controls the LED red and white lights to be in the white light state. Press the function button once to switch the brightness of the white light of the LED red and white lights.

[0014] After the white light brightness is switched, continue to click and press the function button to make the control PCB board enter the infrared camera detection mode. The control PCB board controls the LED red and white lights to be in the red light state. When the red light of the LED red and white lights emits infrared light to illuminate the camera, the camera reflects a red bright spot;

[0015] In the red light state, press the function button twice to make the control PCB board enter the flashing mode, and the white light of the LED red and white light is in the flashing state. Then press and hold the function button for 0.5 seconds to turn off the flashlight.

[0016] When the flashlight is off, long press the function button for three seconds to make the control PCB board enter the buzzer strobe mode. The control PCB board controls the red and white LED lights to be in the white light strobe state and the buzzer sounds an alarm. Long press the function button for three seconds again to turn off the flashlight.

[0017] When the flashlight is off, press the function button twice in succession to make the control PCB board enter the access control mode. The flashlight is vibrated, and the control PCB board controls the white light of the LED red and white lights to be in a flashing state. At the same time, the buzzer sounds an alarm. Long press the function button until the flashlight is turned off.

[0018] Preferably, the decorative plate is configured as an acrylic transparent plate, and a display light is fixedly installed inside, and the display color and state of the display light change with the current mode of the control PCB board.

[0019] Preferably, the control PCB board is also fixedly mounted with a Type-C charging port, and the outside of the Type-C charging port is blocked by a charging interface waterproof plug embedded in the aluminum middle tube.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The push-out arc flashlight, based on the previous multi-functional flashlight, cancels the tail cover setting and sets the arc function to a push-out type. When using the arc function, it is only necessary to move the push plate to make the ceramic head extend out of the zinc alloy ignition head to generate an arc. It is easy to use and is more conducive to timely protection of one's own safety. When the arc function is not in use, the ceramic head is hidden in the zinc alloy ignition head, and will not cause damage or accidental injury to the ceramic head. BRIEF DESCRIPTION OF THE DRAWINGS
