Kind Code:

A1

Abstract:

An electronic atomization device having a digital air pressure sensing chip, comprising an atomization apparatus (1) and an atomization unit (11) in the atomization apparatus (1), a power output unit (3), a microcontroller (4) and a digital air pressure sensing chip (5); the power output unit (3) is used for outputting a voltage to the atomization unit (11) for operation, the microcontroller (4) is electrically connected to the atomization unit (11), the power output unit (3) and the digital air pressure sensing chip (5); the digital air pressure sensing chip (5) is arranged in an air inlet channel (10) of the atomization apparatus (1) or is in communication with the air inlet channel (10), the digital air pressure sensing chip (5) comprises an air pressure sensing module (51), an air pressure processing module (52), a switch signal output module (53) and a digital signal output module (54); the air pressure sensing module (51) is used for detecting the air pressure difference between the air pressure in the air inlet channel (10) and the external air pressure, the air pressure processing module (52) is used for performing operation processing on the air pressure difference detected by the air pressure sensing module (51) and transmitting the operation processed air pressure difference value to the switch signal output module (53), the switch signal output module (53) is used for outputting a switch signal to wake up the dormant microcontroller (4) when the air pressure difference value reaches a set wake-up threshold, and the digital signal output module (54) is used for outputting the operation processed air pressure difference value to the microcontroller (4); and the microcontroller (4) comprises an output switch module (41), and when the air pressure difference value reaches a set operation threshold, the output switch module (41) controls the power output unit (3) to output a voltage, and when the air pressure difference value is lower than the operation threshold, the output switch module (41) controls the power output unit (3) to stop outputting the voltage. Also provided is a control method for an electronic atomization device having a digital air pressure sensing chip (5).
