Description

Smart charging device with UV lamp sterilization and control method thereof

The present invention provides a smart charging device with UV lamp sterilization and a control method thereof, especially a charging module and a UV germicidal lamp group are arranged inside the body of the smart charging device, besides having the function of charging mobile devices In addition, the ultraviolet sterilization function is also designed to ensure the safety of use.

According to the current rapid development of electronic technology and multimedia information, smart phones, tablet computers, notebook computers and other electronic devices are all developing towards the trend of lightness, thinness, shortness, smallness, and powerful functions, mainly with small size, light weight and convenience. Portability and other features, coupled with the continuous innovation of software and hardware functions, make it more flexible and practical in use. As the processing speed and computing performance of electronic devices continue to improve, the power of their batteries will be depleted faster. In order to meet the needs of charging and replenishing the batteries of electronic devices, environments where electronic devices are generally used (such as schools, offices or Public places, etc.), most of them are equipped with fixed-point or mobile charging devices (such as charging cars or charging cabinets, etc.), which can provide charging for multiple electronic devices.

In view of the above-mentioned use environments of charging vehicles or charging cabinets, most of them are used in schools or public places for specific personnel. Therefore, in the process of use, it is easy to cause pathogens such as bacteria and viruses. Residues on the surface make it easy for users to infect each other during the process of taking or touching them with their hands, which will cause safety to human health. Although the traditional method of spraying or wiping with detergent or alcohol can achieve the functions of disinfection and sterilization, if the user's hands accidentally come into contact with the detergent or alcohol, it is easy to damage the skin. Cause irritation or chemical residues, and after a while, it is easy to perform disinfection and sterilization actions due to negligence or fatigue.

Therefore, in today's era of climate change and globalization, which has caused many bacteria or viruses to spread in the environment, how can manufacturers design a smart charging device that can charge electronic devices and supplement the sterilization function to ensure that the Safety is an important issue that needs to be improved urgently by those engaged in this industry.

Therefore, in view of the above deficiencies, the inventor collects relevant information, conducts evaluation and consideration from various parties, and continues to experiment and revise with years of experience accumulated in this industry, before designing such a smart charging device with UV lamp sterilization and its control. The method invention patent was born.

The main purpose of the present invention is to provide a charging module and a UV germicidal lamp group inside the body of the smart charging device (such as a charging car, a charging cabinet, etc.), wherein the power supply circuit of the charging module is connected with a power input unit and a charging unit. It has a drive control circuit in the UV germicidal lamp group, and is connected to a UV lamp through a starting unit. In addition to the charging function, it also has a UV sterilization function. When the microcontroller of the drive control circuit detects that the start The safety activation switch of the unit has been activated by the user, and when the door sensor switch detects that the door cover of the main body is closed, the power relay will be controlled to provide power to the electronic ballast to activate the UV lamp to sterilize the mobile device. Mechanism, when the microcontroller starts timing and reaches the set sterilization time, it will turn off the power of the UV lamp, so that the user is not easy to infect each other and cause harm to the human body during the process of taking or using the mobile device, and it can ensure the safety of use. sex.

The secondary purpose of the present invention is that the body of the smart charging device can be in the form of a charging car or a charging cabinet. The indicator light on the illuminated button switch will light up, which means that the UV lamp sterilization function has entered the ready-to-start state. At this time, if the door cover of the main body is open, the door sensor switch will not be activated, and the UV lamp will not be activated. This is a mechanism to prevent the user from accidentally activating the sterilization function to prevent the leakage of ultraviolet rays from harming the human body. Only after the door sensor switch is activated, the UV lamp will be activated to the built-in mobile device. Irradiate ultraviolet rays to complete the action of disinfection and sterilization.
