Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarette microphone heads, and more specifically, to a trigger threshold variable electronic cigarette microphone head and an application method thereof. Background Art

[0002] The electronic cigarette microphone head is designed based on the principle of a parallel plate capacitor, and a capacitive structure is composed of a diaphragm and a plate. When the user inhales, the air flow differential pressure deforms the diaphragm, resulting in a change in capacitance value. After being processed by the chip, it triggers the start or stop of the electronic cigarette;

[0003] Currently, the air flow channels on the used electronic cigarette microphone heads are usually directly connected and arranged on the air path of the electronic cigarette, and the trigger threshold of the electronic cigarette microphone head is a constant value. This kind of design has the following defects: the trigger sensitivity of the electronic cigarette microphone head cannot be adjusted, and it is difficult to be suitable for user groups with different inhalation forces; Chinese Patent, Application No. 202111000382.4 provides an electronic cigarette circuit, an electronic cigarette control method and an electronic cigarette. By connecting a controllable capacitor in parallel on the microphone head, the purpose of capacitance value adjustment is completed. Although the adjustment purpose can be achieved, this method adds a capacitor, which requires a relatively complex calculation algorithm setting. At the same time, the added capacitor also needs to consider the installation space problem. Limited by the development trend of the increasingly shrinking volume of the electronic cigarette, the space will be very cramped.
