Application circuit for enabling electronic cigarette to implement forward and reverse connections

Abstract

The invention discloses an application circuit for enabling an electronic cigarette to implement forward and reverse connections. The application circuit comprises a power supply circuit arranged in acigarette rod and a control circuit arranged in a cartridge; power supply ends of the power supply circuit are coupled with receiving ends of the control circuit; an output end of the power supply circuit is electrically connected with a load in the cartridge; the power supply ends comprise a first power supply end and a second power supply end; the receiving ends comprise a first receiving end and a second receiving end which are correspondingly connected with the first power supply end and the second power supply end; both ends of the load are respectively connected with the first receivingend and the second receiving end; the control circuit comprises a cartridge chip; and identification circuits formed by diodes and controllable switching tubes are arranged at IO ends of the cartridge chip. The cartridge chip can identify anodes and cathodes of the power supply ends by the identification circuits so as to implement normal power-on of the cartridge, and thus, the cartridge and thecigarette rod can be randomly in forward and reverse connection for use.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an application circuit for forward and reverse connection of electronic cigarettes. Background technique [0002] E-cigarette is an electronic product that imitates cigarettes. It is a product that allows users to smoke after turning nicotine into vapor through means such as atomization. [0003] Although e-cigarettes have different styles or brands, general e-cigarettes are mainly composed of cartridges containing nicotine solution and tobacco rods. The pod is powered by the pod, which can convert the liquid nicotine in the pod into a mist, so that the user has a smoking-like feeling when inhaling, and realizes "smoking". It can even add various flavors of spices such as chocolate and mint to the pipe according to personal preference. [0004] At present, in the electronic cigarette industry, the main connection methods between the pod and the device are 3-wire (...

AI Technical Summary

Problems solved by technology

Among them, the pod chip of type A pod uses a single-wire communication chip, its logic application is relatively simple, the cost of the chip is relatively high, and it can only store information, and cannot perform other logic control functions; the pod chip of type B pod The two-wire communication chip is used, and there will be one more pin in the connection with the pod, and the cost will also increase compared with the A-type pod.

[0005] The pod chips used in the above two types of pods do not have the function of anti-reverse connection, and both need to have a fool-proof mechanism in the product structure, otherwise the pods will be damaged or not work properly, which will seriously affect the user experience.
