Abstract

The invention relates to a charging circuit for a root canal length measuring instrument and a charging state feedback and display method. The charging circuit comprises a lithium battery charging module, a charging state detection module, a single chip microcomputer, a display screen, a green LED lamp driving module and a yellow LED lamp driving module. The output end of the lithium battery charging module is connected with the input end of the charging state detection module, the output end of the charging state detection module is connected with the charging state detection end of the single chip microcomputer, the data display end of the single chip microcomputer is connected with the display screen, the green LED control signal end of the single chip microcomputer is connected with the green LED lamp driving module, and the yellow LED control signal end of the single chip microcomputer is connected with the yellow LED lamp driving module. The charging state of a battery is detected through the single chip microcomputer, a corresponding pattern is displayed through the display screen to inform a user of the charging state of the battery visually, charging indicator lamps are controlled by an IO interface of the single chip microcomputer, and it is avoided that a green LED and a yellow LED light together to bring about error indications.

Description

technical field [0001] The invention relates to the technical field of power supply or power distribution circuit systems, in particular to a charging circuit of a root canal length measuring instrument with charging state feedback and display and a charging state feedback and display method thereof. Background technique [0002] The root canal length measuring instrument (referred to as "root tester") is a kind of dental auxiliary equipment used to measure the length of the root canal of the tooth. The actual length of the zone. When the root canal length measuring instrument is used, the root canal file is inserted into the root canal of the tooth, and then the root canal file is connected to the circuit of the root canal length measuring instrument host; the other electrode of the root canal length measuring instrument host is connected to the Lip hook circuit connection. The root canal file emits two currents of different frequencies in the root canal of the tooth. The...
