Example Embodiment

[0023] Example one, by figure 1 Given, the electronic cigarette application circuit provided by the present invention that can be reversed includes: a control circuit 210 arranged in the cartridge 200 and a main control board arranged in the cigarette stick 100 for supplying power and communication to the control circuit 210 110. A power supply circuit is provided on the main control board 110 for supplying power to the control circuit 210. A load 220 is provided in the cartridge 200, and the control circuit 210 is used to drive the load 220 to work normally. The load 220 can be heating wire or LED lamp, etc.

[0024] The power supply circuit has a power supply terminal, and the control circuit 210 has a power receiving terminal. When the cartridge 200 is connected to the cigarette rod 100, the power supply terminal of the power supply circuit is coupled to the power receiving terminal of the control circuit 210. Specifically, the power supply terminal includes a first power su...

Example Embodiment

[0034] The second embodiment, on the basis of the first embodiment, by figure 2 Given that the main control board 110 is provided with a control chip for data exchange with the cartridge chip U1 and a first communication terminal 113 connected to the IO terminal of the control chip. The IO1 terminal of the cartridge chip U1 is connected with the first communication The second communication terminal 213 to which the terminal 113 is coupled. After the normal power supply between the cartridge 200 and the cigarette rod 100 is achieved, the IO3 terminal of the cartridge 200 chip communicates with the control chip on the main control board 110 through a single bus protocol, exchanges cartridge ID, stores data and control information, etc. , Recognize the identity of the cartridge 200, and determine whether the cartridge 200 is a cartridge 200 that matches the cartridge 100.

Example Embodiment

[0035] The third embodiment, on the basis of the second embodiment, by image 3 Given that the control circuit 210 also includes a control switch circuit 230, the controlled terminal of the control switch circuit 230 is connected to the IO4 terminal of the cartridge chip U1, and the control switch circuit 230 is connected to the power supply line of the load 220. In this embodiment, the control switch circuit 230 uses a controllable switch tube K5 as the control circuit 210. Specifically, the controllable switch tube K5 is a P-type MOS tube.

[0036] After the main control board 110 successfully communicates with the cartridge 200 chip, the cartridge 200 chip can control the opening and closing of the controllable switch K5 through the identification result, thereby controlling the power supply circuit of the load 220. When the identification result is that the cartridge 200 does not match the cigarette rod 100, the cartridge 200 chip controls the controllable switch tube K5 to o...

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 (...
