Title:
CHARGING CIRCUIT AND ELECTRONIC CIGARETTE
Document Type and Number:
WIPO Patent Application WO/2019/174415
Kind Code:
A1
Abstract:
Provided is a charging circuit, comprising a first charging module, a second charging module and a monitoring module, wherein the first charging module and the second charging module are both respectively connected to a main control circuit, an external power supply and a battery; and a monitoring end of the monitoring module is connected to a power supply input end of the first charging module, and an output end of the monitoring module outputs a monitoring voltage to a power supply monitoring input end of the main control circuit, so that the main control circuit enables an enabling end of the second charging module to charge the battery when a charging detection output end of the first charging module outputs a signal indicating that charging is being performed, and when the monitoring voltage is not lower than a steady threshold voltage. Further provided is an electronic cigarette. According to the charging circuit and the electronic cigarette of the present invention, through carrying out charging control by means of a connected main control circuit, a battery is intelligently charged, and a charging circuit does not use an inductor occupying a larger space, so that the occupied space area is small and the cost is low. The electronic cigarette has the characteristics of being small and portable.
