Description

A household flashlight

technical field

The utility model belongs to the technical field of lighting tools, in particular to a household flashlight.

Background technique

Flashlight is a common daily necessities in life. At the same time, the power of existing flashlights cannot be used for a long time. When using it, there is often a phenomenon of insufficient power, or sometimes forget to charge after use, and the power is cut off. At this time, the flashlight is due to It cannot be used without electricity, and there is no cooling device installed on the circuit board of the existing flashlight, which causes the circuit board to work at a high temperature, resulting in shortened service life of the circuit board.

Utility model content

The purpose of this utility model is to provide a household flashlight to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides a technical solution: a household flashlight, including a reflector, a cooling plate, a storage battery, a generator set, a barrel body, a circuit board and an LED lamp, and transparent glass is installed on the reflector. A reflector is installed on the barrel body, a tail cap is installed on the barrel body, a switch is arranged on the outer surface of the barrel body, a plug is installed inside the tail cap, and an insulating slider is provided on the plug, so The battery is installed in the barrel, the engine unit is installed on the right side of the battery, the generator is provided with a rocker, the circuit board is installed at the outlet of the barrel, and a heat sink is installed on the circuit board. The LED lamp is electrically connected to the circuit board through the heat dissipation plate.

Preferably, the electrical input of the storage battery is connected to a circuit board, and the electrical input of the circuit board is connected to an LED lamp.

Preferably, grooves corresponding to the rocker are provided on the outer surface of the barrel.

The technical effects and advantages of the utility model: the household flashlight is equipped with a heat dissipation plate on the circuit board, which can effectively dissipate the heat generated by the circuit board and the light source in time when the circuit board is working, ensuring that the circuit board and LED The service life of the lamp, a generator set is installed in the barrel. When the flashlight is used for a long time or forgets to charge and the flashlight is used, you can generate electricity by shaking the rocker, so that the flashlight can continue to perform lighting work. There is a concave on the barrel. The groove allows the rocker to be put into the groove when not in use, without affecting the grasp of the cylinder body. The reflector is installed to be recessed inward, which is conducive to the gathering of light and increasing the brightness of the lighting.
