Submersible flashlight capable of floating on the water

Abstract

The invention relates to a submersible flashlight capable of floating on the water, wherein a waterproof gasket and a light-admitting lens which are embedded and positioned inside a front cover, the front end of a cylinder body expands outside to form a holding chamber for holding a lamp cup, a screw thread section on the external edge of the holding chamber is combined with the screw thread of the front cover, a waterproof gasket is sleeved on the inner end of the screw thread section, a waterproof gasket is sleeved on the inner end of a screw thread section formed by the external edge of the bottom end of the cylinder body, the screw thread section is combined with the screw thread of a back cover, the inside of the back cover is provided with a switching group, the outside of the switching group is provided with a waterproof gasket, and the waterproof gasket is combined with the outside of the switching group through a through-hole on the back cover. By adopting the structure, when falling in water, the flashlight can not sink into the water bottom and can float on the water so that the person working above the water can fast and conveniently pick up the flashlight when dropping the flashlight, and the person who falls in water and is in danger can use the flashlight for calling for help.

Description

technical field [0001] The invention relates to a flashlight, in particular to a flashlight capable of floating on water. Background technique [0002] In the current existing technology, in daily life, there are often opportunities for temporary lighting, such as: suddenly entering a dark room and cannot find the light switch for a while, or suddenly turning off the power in the room at night, or unlocking the door at night, Or looking for things in the dark, etc., all need an immediate light source, so as to immediately improve the inconvenience caused at that time. [0003] Generally, the existing common flashlight structure is mainly composed of a main body, a lampshade base and a bottom cover. There is a light-emitting component inside the top of the body, and the battery is used as the main source for the light-emitting component to shine, and a switch part is used to control the light-emitting component. Turn on or off the lighting function, and the battery in the bo...

Problems solved by technology

[0004] Yet generally existing various flashlight structures, although all can achieve the effect of lighting to provide people with appropriate lighting, but in its actual operation and use, it is found that this type of flashlight structure can only simply emit light for lighting, and it has the following disadvantages: (1) This type of flashlight does not have any waterproof design, which makes it easy for moisture to invade the interior of the flashlight during use, causing the internal circuit of the flashlight and the metal conductive sheet to be damp, rusted or even damaged.

(2) This type of flashlight not only does not have any waterproof design, but also cannot float on the water surface, so that once it falls into the water, it will quickly sink to the bottom, especially for people working on the water surface, flashlights often fall In the water, sink into the bottom of the water, and cannot be picked up or damaged by submersion, resulting in great loss in use

(3) This type of flashlight generally sets the control switch to control its on-off state on the side edge of the body, or directly uses the body and the lampshade seat or the bottom cover to tighten and loosen the flashlight to control the on-off state of the flashlight, so that it can be used to control the flashlight. The design of the blinking control switch does not have the function of waterproof and pressure resistance, so it cannot be used in water
