  • Publication number: 20220338551
    Abstract: The present disclosure provides a method for controlling an electronic cigarette and an electronic cigarette. The electronic cigarette comprises an airflow sensor. The control method comprises: measuring whether a duration of a low-level signal sent by the airflow sensor is greater than a preset threshold; if so, when a high-level signal sent by the airflow sensor is received, responding to the high-level signal so as to control the electronic cigarette to operate; and if not, when a high-level signal sent by the airflow sensor is received, not responding to the high-level signal. In the above control method, it is determined, according to the duration of the low-level signal generated by the airflow sensor, whether to respond to triggering of the high-level signal so as to cause the electronic cigarette to operate.

  • Patent number: 10912338
    Abstract: An electronic cigarette includes: an atomizer, defining a liquid storage chamber formed therein; a heating element, communicated with the liquid storage chamber; a power supply, configured for supplying power; a controlling unit, one end of the controlling unit electrically connected with the power supply, the other end thereof electrically connected with the heating element; and a capacitive transducer electrically connected with the controlling unit. Two electrodes are disposed inside the liquid storage chamber for determining an amount of the tobacco liquid in the liquid storage chamber. A using method includes: conducting the electricity and controlling the heating element to atomize the tobacco liquid in the liquid storage chamber; detecting an amount of the tobacco liquid in the liquid storage chamber via the capacitive transducer. When the detected amount of the tobacco liquid reaches a preset value, the electronic cigarette emits alert information or cuts off the electricity.

  • Publication number: 20210011929
    Abstract: The present invention discloses a method for creating relational database table (s) for a form, which relates to the technical field of software development. A form is mapped to two database tables: a Table Main and a Table Detail, wherein the Table Main is used for storing the attributives of the table header and footer; the Table Detail is used for storing the attributives of the table body; the records of the two tables are associated by header numbers, which are primary keys, not combinations of primary keys from external entities, but independently generated serial numbers with business meaning. The application of the present invention solves the problems of redundant storage and slow access.
