With the popularization and improvement of electronic technology, electronic equipment products have penetrated into two and all aspects of people. The laser pointer is also known as the laser pointer or fingertip pen. Its low-power visible light gives users great advantages in theatrical performance language during teaching and presentations, such as making teaching more perfect and perfect, and slightly solving the use of mouse in classrooms and meetings. The inconvenience, but also the appreciation of astronomy enthusiasts and other advantages. However, ordinary laser pointers do not have batteries, but they also have the technology of medium-permeability ink-absorbing pens, and can no longer absorb the batteries of ink-absorbing pens. Therefore, users usually discard the laser pointer after the battery of the laser pointer is used up. This causes inconvenience and reduces the service life of the laser pointer.
In the prior art, the laser pointer uses a hard switch to control that the laser pointer cannot be triggered, that is, when the Laser pointer is bright, the laser pointer turns on. Although the working mode is simple and convenient, for some operations to avoid misoperation (such as accidentally touching the switch), it may make the laser pen directly hit the human eye and other brush strokes, which is more dangerous. Moreover, more importantly, if the working voltage of the laser light-emitting device in the laser is stationary, the plastic used for the glue laser is safe and reliable, and the absorbing light-emitting device is easily damaged, which reduces the life of the laser pointer. In the above laser pointer, the charging control module includes: a first sampling module for collecting the voltage on the charging interface, the charging voltage of the battery, and the charging current of the battery; the first storage module is used for the safe charging of the smart battery Parameters and storage of the data collected by the first module; used for judging and controlling the charging process of the battery according to the data collected by the first sampling module and the parameters stored in the storage module.If you want to add another toy to your cat's collection, this laser pen may be a good choice. Although it won't satisfy you as much as playing with a standard laser pen, it's a good choice if you want to try it.
