Abstract

The invention discloses a drive circuit of a fine engraving instrument. The circuit includes an optocoupler isolated input signal circuit, 4M active crystal oscillator signal circuit, logic gate control circuit, primary signal amplifying circuit. A secondary signal amplification circuit and a terminal signal output circuit. At that output end of the optocoupler isolate input signal circuit and the4M active crystal oscillator signal circuit, The output end of the logic gate control circuit is connected with the input end of the primary signal amplification circuit, the output end of the primary signal amplification circuit is connected with the input end of the secondary signal amplification circuit. And the output end of the secondary signal amplification circuit is connected with the input end of the terminal signal output circuit. The invention ensures the isolation of the signal input terminal and the subsequent driving signal, and reduces the interference between each other. The 4M active crystal oscillator signal is used as the driving signal to drive MOS transistor, which ensures the frequency stability of the input signal source. The first-order signal amplification circuitguarantees the advantages of the second-order signal driving ability.

Description

technical field [0001] The invention relates to a drive circuit for Jingdiao instrument. Background technique [0002] Ultrasound is an oscillating sound pressure wave with a frequency greater than the upper limit of the human hearing range. Thus, ultrasound in healthy young adults is about 4-7 kHz (4-70,00 Hz). Ultrasound equipment operates at frequencies from 4-7kHz to several gigahertz. [0003] Nowadays, there are many beauty instruments radar line engraving applied to radar mechanical waves. There are many problems. The common one is that the continuous output energy is unstable. During the treatment process, some medical accidents have occurred, and some may cause facial curve deformation and rapid aging of the probe. , or there is no effect after treatment, the probes provided by different manufacturers are not compatible, the energy difference is large, and many other problems. Contents of the invention [0004] The purpose of the present invention is to overcom...
