Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] Such as Figure 1 to Figure 5 As shown, a highly integrated electronic cigarette lighter chip includes a chip body 1, a USB port 2 connected to the chip body 1, a heating wire 3 connected to the chip body 1, and a An indicator light 4 connected to the body 1, a lithium battery 5 connected to the chip body 1, and a button 6 connected to the chip body 1. The USB port 2 is used to charge the electronic cigarette lighter. When the button 6 of the electronic cigarette lighter is pressed, the lithium battery 5 supplies power to the heating wire 3 to generate heat, thereby realizing lighting the cigarette.

[0025] The chip body 1 is provided with a KEY terminal connected to the button 6, an LED terminal connected to the indicator light 4, a VIN terminal connected to the USB port 2, and a VIN termi...

Abstract

The invention relates to the technical field of cigarette lighters, in particular to a highly-integrated electronic cigarette lighter chip. The highly-integrated electronic cigarette lighter chip comprises a chip body, a USB port connected with the chip body, an electric heating wire connected with the chip body, an indicating lamp connected with the chip body, a lithium battery connected with thechip body, and a key connected with the chip body. The chip integrates a charging chip, a single chip microcomputer chip and an MOS switch chip to achieve miniaturized package, thus the whole circuitscheme is very simplified and compact, the capacity of the lithium battery is increased, the service time is prolonged, and the cost is greatly lowered; the chip internally adopts a switch driving module and an NMOS switch to achieve turning on and off of a discharge switch, switch conduction impedance is greatly lowered, then damage to the chip is reduced, heating is lowered, and reliability isimproved.

Description

technical field [0001] The invention relates to the technical field of cigarette lighters, in particular to a highly integrated electronic cigarette lighter chip. Background technique [0002] Cigarette lighters, such as lighters and electronic cigarettes, are traditionally composed of electronic switches and liquefied gas (oil), which is poor in reusability, and is flammable and explosive, posing safety hazards. [0003] With the deepening and popularization of lithium battery industrialization, more and more devices use lithium batteries as energy sources. Especially after the volume of the polymer lithium battery has been miniaturized, it is possible to use the lithium battery as the energy source on the cigarette lighter. Moreover, the lithium battery can be charged and discharged repeatedly, and the charging interface is compatible with microUSB, so charging is convenient. [0004] The internal structural components of existing electronic cigarette lighters include: l...
