Electronic cigarette and power supply structure thereof

Abstract

The invention relates to a power supply structure comprising at least two rechargeable batteries connected in series and a charging circuit. The charging circuit connected with the rechargeable batteries is used for charging the rechargeable batteries. In addition, the power supply structure also includes a switching circuit connected with the at least two rechargeable batteries. The switching circuit is used for switching the at least two rechargeable batteries to a battery series circuit with different numbers of rechargeable batteries connected in series; and the charging circuit is used for detecting the voltage of the battery series circuit, converting a standard charging voltage into different charging voltages based on the detected voltage, and providing the voltages for charging of the battery series circuit. On the basis of the power supply structure, switching usage of charging one or more series batteries by one same circuit can be realized. The number of batteries is identified based on the detection voltage; and a corresponding charging scheme is provided based on the corresponding battery number. In addition, the invention also discloses an electronic cigarette including the power supply structure.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette and its power source structure. Background technique [0002] Rechargeable batteries are widely used as a portable and easy-to-use power source. Usually, according to the different supply voltages, different numbers of rechargeable batteries are used in series to achieve the effect of adapting to different supply voltages. However, in the traditional scheme, there is only a power structure design scheme for the charge and discharge of a single battery or two or three batteries in series, and it is impossible to realize that the same circuit can be used to switch the number of one, two and three batteries in series. Therefore, when we are charging, increasing or decreasing the number of batteries, we need to replace the adapted charging and discharging power structure at the same time, resulting in poor adaptability of the power structure, wh...

Problems solved by technology

However, in the traditional scheme, there is only a power structure design scheme for the charge and discharge of a single battery or two and three series batteries, and it cannot be achieved that the same circuit can be used for switching the number of one, two and three series batteries.

Therefore, when we are charging, increasing or reducing the number of batteries, we need to replace the adapted charging and discharging power structure at the same time, resulting in poor adaptability of the power structure, which is not conducive to people's use
