Abstract

The invention relates to the technical field of an electronic circuit, and specially relates to an electric sprayer special-purpose voltmeter circuit. The electric sprayer special-purpose voltmeter circuit comprises a first voltage-stabilizing tube (DZ1), a second voltage-stabilizing tube (DZ2), a first light emitting diode (D1), a second light emitting diode (D2), a third light emitting diode (D3), a first resistor (R1), a second resistor (R2) and a third resistor (R3). A power supply VCC is respectively connected with one end of the third resistor (R3) and the anode of the second voltage-stabilizing tube (DZ2), and the other end of the third resistor (R3) is connected with the anode of the third light emitting diode (D3). According to the invention, through adoption of LED lamp beads of the light emitting diodes as voltage indication, conventional second hand meter indication is replaced, the indication is flexible and accurate, the reliability is high, misoperation is avoided, and the service life of an electric sprayer can be effectively prolonged. Besides, the voltmeter circuit is simple in structure and easy to realize.

Description

Technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a voltmeter circuit dedicated to an electric sprayer. Background technique [0002] At present, all domestically produced electric sprayer voltmeters use the second hand to indicate. However, the voltmeter with the above-mentioned structure has inflexible indication, accuracy, and poor reliability, and is prone to misoperation, thereby shortening the service life of the electric sprayer. Summary of the invention [0003] The purpose of the present invention is to provide a special voltmeter circuit for an electric sprayer with flexible indication, accuracy and high reliability, and avoiding misoperation, thereby effectively prolonging the service life of the electric sprayer. [0004] In order to solve the problems in the background art, the present invention adopts the following technical solution: a dedicated voltmeter circuit for an electric sprayer, including a first vol...
