Abstract: A low voltage charging control and protection circuit for an electronic cigarette is provided. The circuit includes an extended charging circuit configured to charge a battery of the electronic cigarette at a first voltage. The circuit also includes a charging integrated circuit configured to charge the battery of the electronic cigarette at a second voltage. The first voltage is lower than the second voltage. The circuit further includes a microcontroller configured to control the extended charging circuit and the charging integrated circuit to alternately charge the battery of the electronic cigarette based on a high or low level of a voltage of the battery.

Abstract: The present disclosure provides a dual-seal reverse pressure differential cartridge E-liquid injection method. The method includes: selecting an E-liquid guiding body configured to absorb, to a maximum degree, an E-liquid stored in an E-liquid storage tank, to avoid leakage of the E-liquid, while providing a smooth supply of the E-liquid. The method also includes assembling the E-liquid guiding body with a cartridge that includes an E-liquid storage tank. The E-liquid guiding body is in fluidic communication with the E-liquid in the E-liquid storage tank. In a negative pressure environment, the E-liquid is injected into the E-liquid storage tank. The E-liquid has a pressure P1. After the injection is completed, the cartridge is placed in a sealing bag, which is then sealed. The pressure inside the sealing bag is P2, P2>P1. The disclosed method can effectively avoid leakage of the E-liquid due to pressure changes in the external atmosphere.

Abstract: The present invention provides an atomization generating device for e-cigarettes, comprising an e-liquid storage portion for storing and supplying an e-liquid, an atomizing portion for heating and atomizing the e-liquid, and a sealing portion located between the e-liquid storage portion and the atomizing portion, wherein the e-liquid storage portion and the atomizing portion are designed to be relatively movable to isolate the sealing portion to prevent the e-liquid leakage caused by long-term placement. Before use, e-liquid in the storage tank is not in contact with the outside, which ensures the quality and taste of the e-liquid. When in use, e-liquid flows towards the heating component, and when not in use seals the e-liquid; thereby prolonging storage life of e-liquid, and preventing e-liquid from contacting outside air, and being oscillated by the outside and from flowing out and leaking.
