Atomization control device and control method

Abstract

The invention discloses an atomization control device and a control method, comprising a PIC single-chip microcomputer, a temperature sampling circuit, an oil pump driving circuit and an electric heating tube driving circuit, and the temperature sampling circuit, the oil pump driving circuit and the electric heating tube driving circuit are all connected to the PIC single-chip microcomputer , the temperature sampling circuit is also connected with the electric heating tube driving circuit; the electric heating tube driving circuit includes an electric heating tube, and a heating wire is arranged inside the electric heating tube; the temperature sampling circuit collects the temperature of the heating wire, and feeds back the temperature of the heating wire to the PIC microcontroller, and the PIC The single-chip microcomputer adjusts the PWM pulse width, and then outputs power to the electric heating tube driving circuit through the pin, and the heating wire quickly heats up to the reference temperature. The PIC single-chip microcomputer drives the oil pump to work through the oil pump driving circuit. To the inside of the electric heating tube, the aerosol is rapidly expanded and atomized by heat, and then the smoke is sprayed through the nozzle of the electric heating tube. The PIC microcontroller adjusts the PWM pulse width duty cycle through the internal PID regulator, and then adjusts the output power.

Description

technical field [0001] The invention relates to the technical field of atomization equipment, in particular to an atomization control device and a control method. Background technique [0002] At present, due to the existence of non-linear characteristics such as large inertia, large time variation, and pure hysteresis of the heating wire, the traditional smoke electromechanical heating technology mainly uses no feedback or the temperature switch cuts off the power supply of the control relay to achieve the purpose of changing the heating power output. The traditional smoke The fog machine has the following technical problems: on the one hand, the fog machine is affected by the error of the instrument itself and the electrical life of the temperature switch, the on-off frequency is low, and the temperature fluctuation range is large; on the other hand, the traditional fog machine has a large volume and needs to be used in practical applications AC voltage power supply, at th...

[0002] At present, due to the existence of non-linear characteristics such as large inertia, large time variation, and pure hysteresis of the heating wire, the traditional smoke electromechanical heating technology mainly uses no feedback or the temperature switch cuts off the power supply of the control relay to achieve the purpose of changing the heating power output. The traditional smoke The fog machine has the following technical problems: on the one hand, the fog machine is affected by the error of the instrument itself and the electrical life of the temperature switch, the on-off frequency is low, and the temperature fluctuation range is large; on the other hand, the traditional fog machine has a large volume and needs to be used in practical applications AC voltage power supply, at the same time, the traditional smoke machine needs to be warmed up before it can be used normally, and cannot be carried around
