Title:
ELECTRONIC CIGARETTE HAVING DOUBLE AIR PRESSURE SENSORS AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/038184
Kind Code:
A1
Abstract:
The present invention relates to an electronic cigarette having double air pressure sensors and a control method therefor. An atomizer of the electronic cigarette comprises a mouthpiece, an atomization tube, and a liquid storage cup, a heating apparatus and an atomization channel arranged in the atomization tube; a heating resistor is arranged in the heating apparatus; a battery, a control circuit board and an air inlet channel are arranged in a battery rod; a micro-control switch, a micro-controller and a power adjustment module are arranged on the control circuit board; and double air pressure sensors comprising a switch air pressure sensor and a digital air pressure sensor are arranged in the air inlet channel, wherein the switch air pressure sensor detects whether the inhalation force reaches a switch value so as to turn on or turn off the micro-control switch, and the digital air pressure sensor detects the magnitude of the inhalation force during the operation of the heating resistor so as to control the amount of vapor. The beneficial effects thereof are that the electronic cigarette has the switch air pressure sensor and the digital air pressure sensor, so that the amount of vapor can be adjusted according to the inhalation force, and the electronic cigarette can be automatically started and hibernated according to the inhalation force so as to save electric energy, thereby prolonging the battery usage time and life.
