Abstract

The invention discloses a flashlight. The flashlight comprises a cylinder, a handle, a first battery, a second battery, a first charging device, a light emitting device and a circuit board. The handle is rotationally mounted in the cylinder; the first charging device is mounted on the handle, and is used for charging the first battery; the light emitting device is mounted in the cylinder, and is used for providing illumination; the circuit board is mounted in the cylinder, and is used for driving the light emitting device; the first battery is mounted in the cylinder, is electrically connected with the circuit board, and is used for supplying power to the light emitting device; and the second battery is mounted in the cylinder, is electrically connected with the circuit board, and is used for supplying power to the light emitting device. The flashlight can supply power to the light emitting device through the first battery and the second battery, so that the illuminating time of the flashlight is longer. When the flashlight is used, the first battery can be charged through the first charging device, so that the power failure is not suddenly generated in the use process of the flashlight, and the use convenience is improved.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to a flashlight. Background technique [0002] Flashlight is a mobile lighting tool commonly used in daily life, with the characteristics of portability, lightness and so on. However, the existing flashlights are often powered by lithium batteries or dry batteries. The power supply mode is single and cannot provide long-term lighting. The situation of sudden power failure often occurs during use, which brings inconvenience to use. Contents of the invention [0003] The purpose of the present invention is to provide a flashlight with multiple power supply modes. [0004] In order to solve the above technical problems, the present invention provides a flashlight, which includes a barrel, a handle, a first battery, a second battery, a first charging device, a light emitting device and a circuit board, the handle is rotatably mounted on the barrel body, the first charging device is ...
