Touch electronic cigarette lighter adopting novel control manner

Abstract

The invention discloses a touch electronic cigarette lighter adopting a novel control manner. The novel control-manner touch electronic cigarette lighter comprises an integrated chip, a T pin of the integrated chip is electrically connected with a touch point in series connection with an R2 resistor, an EN pin of the integrated chip is in series connection with a switch S1, a VDD pin of the integrated chip is electrically connected with a VDD pin of a charging port, an OUT pin of the integrated chip is in series connection with a heating wire, a BAT pin of the integrated chip is electrically connected with a power source, an LED1 pin of the integrated chip is in series connection with LED lamps D1, D2, D3, and D4 which are in parallel connection, and an LED 2 pin of the integrated chip isin series connection with LED lamps D5, D6 and D7 which are in parallel connection. A battery charging control circuit and a cigarette lighter switch are integrated inside, the low input voltage is supported, the novel control manner of a touch switch is adopted, an independent charging system is adopted, cigarette lighting during charging is supported, and during low voltage input, the chip is normally started and controlled.

Description

technical field [0001] The invention relates to the field of electronic cigarette lighters, in particular to a novel touch electronic cigarette lighter with a control mode. Background technique [0002] Electronic cigarette lighter, also known as electronic lighter, can charge the built-in lithium-ion battery through an external power supply. It is a commonly used USB charging interface. It can be directly plugged into the computer USB socket to charge it, or it can be plugged into an AC power supply with a USB socket to charge it. The charging time is 2 to 3 hours to fully charge; the fully charged electronic cigarette lighter can be used to light cigarettes, and it takes 4 to 5 seconds to light a cigarette. Because the heating wire is heated to light the cigarette, there is no open flame, and it is not afraid of wind and cold weather. [0003] However, the existing electronic cigarette lighters use MCU chips to control and drive, and the MCU chips must work at a certain...

Problems solved by technology

[0003] However, the existing electronic cigarette lighters use MCU chips to control and drive, and the MCU chips must work at a certain power supply voltage. When the battery voltage is low, the MCU is prone to crashes; and because the battery voltage is lower than the critical voltage The MCU chip cannot be reset. The existing electronic cigarette lighter uses the MCU chip to control and drive. It needs an external low-resistance mos tube as the conduction switch of the battery and the heating wire. The existing electronic cigarette lighter needs a button switch to turn on the heat. silk work
