CIRCUIT FOR SENSING AND CONTROLLING HEATER VOLTAGE OF ATOMIZER
Document Type and Number:
WIPO Patent Application WO/2021/101228
Kind Code:
A1
Abstract:
The present invention relates to an atomizer for vaporizing an inhalation substance in liquid form and, more particularly, to a circuit capable of sensing and controlling a voltage of a heater without being affected by the power of a battery in an atomizer using a liquid cartridge. The circuit for sensing and controlling a voltage of a heater, according to the present invention, comprises: a battery for supplying power to an atomizer; a microcontroller; a first FET connected to the battery and operating ON/OFF according to a sensing control signal outputted from the microcontroller; a sensing resistor connected to the first FET; a second FET connected to the battery and operating ON/OFF according to a heater control signal outputted from the microcontroller; and a heater resistor connected to the second FET and connected to one end of the sensing resistor, wherein the upper end of the sensing resistor is connected to the microcontroller, one side of the lower end of the sensing resistor is connected to the microcontroller, and the other side of the lower end of the sensing resistor is connected to the second FET.
