The utility model is further described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of the present utility model.

In the figure, a mobile power supply shell, a dry battery, an emergency flashlight, a USB interface, a key switch, a dry battery cabin, a rear shell, a power indicator and a power indicator are arranged in sequence, wherein the power indicator is composed of the mobile power supply shell, the dry battery, the emergency flashlight, the USB interface, the key switch, the dry battery cabin, the emergency flashlight, the power indicator and the power indicator.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Please refer to fig. 1, an emergency type charger capable of replacing a charging battery core with a dry battery, which comprises a mobile power supply housing 1, wherein a dry battery 2 is electrically connected in the mobile power supply housing 1, a battery control main board is arranged in the mobile power supply housing 1, a fast charging protocol chip is arranged in the mobile power supply housing 1 and used for controlling current output, an emergency flashlight lamp 3 and a USB interface 4 are arranged at the front end of the mobile power supply housing 1, a key switch 5 is further arranged at the front end of the mobile power supply housing 1, the key switch 5 is used for controlling the switch of the emergency flashlight lamp 3, a dry battery cabin 6 is arranged on the mobile power supply housing 1, the dry battery 2 is installed in the dry battery cabin 6 to supply power to the mobile power supply, a rear shell 7 is detachably connected at the dry battery cabin 6, and a power indicator lamp 8 used for detecting electric quantity of the dry battery 2 is arranged on the mobile power supply housing 1.

The emergency charger baby is provided with a common No. 5 dry battery 2 by removing the detachable rear shell 7; the single-press key switch 5 is used for adjusting the voltage of the electric quantity of the dry battery 2 by the voltage-increasing and voltage-decreasing chip circuit of the battery control main board, the control of the fast-charging protocol chip is added, the output fast-charging current is output to the USB interface 4 for charging the communication electronic equipment, the fast-charging protocol chip communicates with the main control chip according to the request and the identification of the charged equipment, the information such as the voltage and the current requirement of the equipment is transmitted to the main control chip, the main control chip controls the input and output ports of the charger according to the information transmitted by the fast-charging protocol chip, and the main control circuit for adjusting the output voltage and the current cooperates with the protocol chip to jointly complete the charging task. When the voltage of the main control chip circuit through monitoring the battery pack is lower than a certain value, the main control chip circuit judges that the dry battery pack has consumed electricity, the power indicator lamp 8 displays red, and the power indicator lamp 8 can detect the change of the output power of the charger baby so as to facilitate a user to replace the dry battery 2 in time.

Because the capacity of the existing disposable dry battery is generally low, the battery is generally only suitable for emergency charging, and is convenient for emergency connection with the outside.
