Atomization control device and control method

Abstract

The invention discloses an atomization control device and a control method. The atomization control device comprises a PIC (Peripheral Interface Controller) single chip microcomputer, a temperature sampling circuit, an oil pump driving circuit and an electrical heated tube driving circuit, wherein the temperature sampling circuit, the oil pump driving circuit and the electrical heated tube driving circuit are all connected with the PIC single chip microcomputer; the temperature sampling circuit is further connected with the electrical heated tube driving circuit; the electrical heated tube driving circuit comprises an electrical heated tube with a heating wire arranged therein; the temperature sampling circuit acquires the temperature of the heating wire and feeds the temperature of the heating wire back to the PIC single chip microcomputer; the PIC single chip microcomputer conducts pulse width adjustment via PWM (Pulse-Width Modulation) and outputs power to the electrical heated tube driving circuit through a pin; the heating wire is quickly heated up to a reference temperature; the PIC single chip microcomputer drives an oil pump to work through the oil pump driving circuit; the oil pump pumps a smoke agent through a pipeline and transmits the smoke agent into the electrical heated tube; then the smoke agent is heated and quickly expanded and atomized; smoke is sprayed via the orifice of the electrical heated tube; and the PIC single chip microcomputer adjusts the PWM duty cycle through an internal PID (Proportion Integration Differentiation) regulator to further adjust 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...
