Multifunctional charging type magnifier and control method thereof

Abstract

The invention discloses a multifunctional charging type magnifier and a control method thereof. The charging type magnifier includes a shell, a magnifying lens, a circuit board, and a control device, a rechargeable battery BT1, an illuminating lamp D3 and an ultraviolet lamp D4 which are connected with the circuit board, and a charging interface DC arranged on the shell and connected with the circuit board; and a control management circuit, a charging interface circuit, a drive circuit, a charging management circuit and a charging and discharging protection circuit are arranged on the circuit board. A triggering signal of light touch or long-time pressing of the control device is processed by a miniature single-chip microcomputer, and independent switches and brightness adjustment of the illuminating lamp and ultraviolet lamp are controlled by the drive circuit. The multifunctional charging type magnifier provided by the invention adopts perfect charging and discharging management and a flexible and convenient control mode, improves product reliability, greatly prolongs the service life, has the functions of display and viewing in a magnified manner, illumination, ultraviolet banknote checking and observation of objects sensitive to ultraviolet rays, and is suitable for requirements of different users.

Description

technical field [0001] The invention relates to the field of magnifying glasses, in particular to a multifunctional rechargeable magnifying glass and a control method thereof. Background technique [0002] The magnifying glasses currently on the market have relatively single functions, poor practicability, unstable manipulation, and short service life. Most of the magnifying glasses with lighting function use disposable batteries, which have low capacity and are troublesome to replace the batteries. Due to the limitation of battery capacity, the lighting brightness is low, which cannot meet the requirements of the users for light intensity and long-term use. And the disposable battery has the situation of leaking when used for a long time, which pollutes the product itself and the environment, has poor environmental protection, and reduces the service life of the magnifying glass product. Contents of the invention [0003] The technical problem to be solved by the present...

Problems solved by technology

[0002] The magnifying glass currently on the market has relatively single function, poor practicality, unstable operation, and short service life.

However, most of the magnifying glasses with lighting function use disposable batteries, which have low capacity and are troublesome to replace batteries. Due to the limitation of battery capacity, the lighting brightness is low, which cannot meet the requirements of the users for light intensity and long-term use. In addition, the disposable battery may leak when used for a long time, causing pollution to the product itself and the environment, poor environmental protection, and reducing the service life of the magnifying glass product
