Embodiment

[0009] Embodiment: The structure is shown in the accompanying drawings, consisting of a charging circuit 1 and a thermistor 2 , wherein the thermistor 2 is connected to the output end of the charging circuit 1 . When in use, connect the front end of the temperature-sensitive charger to the power supply, and connect the output end to the rechargeable battery. During the charging process, if the charging current is too large and generates heat, the thermistor 2 connected to the output end will reverse Adjust the resistance value, reduce the charging current intensity, and make the temperature drop. After the temperature drops, or when charging under low temperature in winter, the thermistor 2 will appropriately increase the charging current intensity. The utility model has the advantages of reasonable design, simple structure, high working efficiency and convenient use.

Abstract

The present invention relates to a temperature sensing type charger belonging to electronic products manufacturing technology field. It contains charging circuit and thermistor, wherein thermistor connected to output port of charging circuit. Temperature sensing type charger front end is accessed to power supply, accessing output port to rechargeable cell, in process of charging, if generating charging current overload and heating phenomena, output port connected thermistor reversal adjusting resistance value, reducing strength of charging current, making thermal drop, if charging at winter low-level air temperature, thermistor properly raising strength of charging current.

Description

technical field [0001] The invention relates to a temperature-sensitive charger, which belongs to the technical field of electronic product manufacturing. Background technique [0002] The temperature of the charger will rise during the charging process, but when the temperature is too high, it will cause certain damage to the battery or the charger itself. Now ordinary chargers do not have the function of temperature sensing and automatic adjustment of charging intensity. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a temperature-sensitive charger with reasonable design, simple structure, convenient use and intelligent charging function. [0004] The object of the present invention is achieved through the following technical solutions: a temperature-sensitive charger is composed of a charging circuit and a thermistor, and the thermistor is connected to the output end of the charging circuit. [0005] The thermisto...
