detailed description

The technical solution of this patent will be described in further detail below in conjunction with specific embodiments.

Please refer to Fig. 1-2, a mobile phone charger with automatic timing power-off function, including a two-pin plug 1, a display screen 2, a USB interface 3, a shell 4 and an integrated chip 5, and one end of the shell 4 is provided with two Pin plug 1, the other end of shell 4 is provided with USB interface 3, and the side outside shell 4 is installed with display screen 2, and integrated chip 5 is installed in the inside of shell 4, and integrated chip 5 comprises PCB board 56, captures mobile phone power module 51, Charging time calculation module 52, display countdown module 53, power-off module 54 and mobile phone communication module 55, capture mobile phone power module 51, charging time calculation module 52, display countdown module 53, power-off module 54 and mobile phone communication module 55 are all installed in PCB board 56. The display screen 2 adopts an LED display screen, the maximum current of the USB interface 3 is 0.2A, and the input voltage of the USB interface 3 is 220V.

The working principle of the utility model is: when the user's mobile phone needs to be charged, the two-pin plug 1 of the device is inserted into the plugboard, the USB interface 3 is connected with the mobile phone, and the mobile phone power module 51 of the integrated chip 5 is automatically captured to the mobile phone. Then the charging time calculation module 52 converts it into the required charging time through a series of calculations, and the display countdown module 53 displays the remaining time on the display screen 2 and counts down. After the countdown ends, the power-off module 54 works and the mobile phone is charged. The device will automatically power off to prevent the phone from charging for too long. The device is reasonable in design, small in size, light in weight, easy to carry and store; low failure rate, good operation stability, adopts integrated chip 5, can automatically search for the battery status of the mobile phone, automatically calculate the required charging time and display it on the shell 4 On the display screen 2 of the mobile phone, people can know more about the charging situation of the mobile phone; after the mobile phone is fully charged, the device automatically cuts off the power, which solves people's worries, and has good use safety and use effect.

The preferred implementation of this patent has been described in detail above, but this patent is not limited to the above-mentioned implementation, and within the knowledge of those of ordinary skill in the art, it can also be made without departing from the purpose of this patent. Variations.
