Abstract

The invention relates to a root canal length measuring instrument startup and shutdown circuit with a power switching function. The circuit comprises a power switching circuit, a power switch circuit, a switch driving circuit, a key circuit, a target board and a power adapter, wherein an input end of the power switching circuit is connected with the power adapter, an output end of the power switching circuit is connected with one input end of the power switch circuit, the other input end of the power switch circuit is connected with common terminals of the switch driving circuit and the key circuit, an output end of the power switch circuit is connected with a power input end of the target board, a single-chip microcomputer control signal end of the target board is connected with one input end of the switch driving circuit, the other input end of the switch driving circuit is connected with the power adapter, and a key detection signal end of the target board is connected with an output end of the key circuit. With the adoption of the circuit, startup is quick, and safety and power-saving effects can be realized during shutdown; the service life of a rechargeable battery is prolonged, and the safety degree of the rechargeable battery is increased; direct contract of a human body with a power supply is isolated, and the use safety degree is increased.

Description

technical field [0001] The invention relates to the technical field of dentistry, in particular to a switch circuit of a root canal length measuring instrument with a power switching function. 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, and the host measures the ratio of the resistance values ​​of the two currents passing through the root canal (t...
