Low-temperature baking smoking set with boost and buck functions based on fast charging technology

Abstract

The invention discloses a low-temperature baking smoking set with boost and buck functions based on a fast charging technology, comprising a low-temperature baking smoking set which is composed of a shell and a battery component and a preloaded tobacco baking unit arranged in the shell. The battery component includes a battery and a fast charging circuit. The fast charging circuit includes a backward flow prevention circuit, a boost-buck circuit, a charging current detection circuit, a current limiting control circuit, a driving circuit, an MCU master controller unit, a charging indicator lampand a full charging indicator lamp. Through specific circuit design, the circuit of the invention can prevent backward flow. When the charging input terminal is short-circuited, the battery power will not be output to the outside. A synchronous boost and synchronous buck design is adopted, the voltage drop of the freewheeling diode in the traditional boost-buck circuit is omitted, and the charging efficiency can be up to 87%. The boost-buck switching circuit inside a chip converts 3V-9V DC power input to the charging interface into 4.2V power, and an internal logic circuit is used to controlthe charging current, charging voltage and other parameters.

Description

technical field [0001] The invention relates to the technical field of low-temperature baking smoking utensils, in particular to a low-temperature baking smoking utensil with fast charging technology for buck-boosting functions. Background technique [0002] At present, the low-temperature baking smoking set is provided with a separate power supply to make it easy to carry and easy to use, and most of them have a small battery capacity due to volume limitations, so that in specific use, the interval between each charge is relatively short; Most of the existing charging is direct charging, which saves costs, but the charging time is long and the voltage is unstable, which greatly reduces the battery life, thus affecting the overall life of the low-temperature baking smoking set and greatly reducing the user experience. Contents of the invention [0003] The purpose of the present invention is to provide a low-temperature baking smoking set with fast charging technology with...
