[0035] Ginseng Figure 1 、 2 As shown, the electronic cigarette identity information authentication device of the present invention includes:

[0036] The control unit 110 is arranged in the cigarette rod 100 structure and is connected to the following signal coupling circuit 120 and decoding circuit 130, and is used to send an identity information reading request to the signal coupling circuit 120, receive the identity information decoded by the decoding circuit 130, and compare and authenticate it with the preset identity information; the signal coupling circuit 120 is used to receive the identity information reading request information sent by the control unit 110, and transmit the information to the identity information unit 140; the identity information unit 140 is arranged in the cigarette cartridge 200 structure, and is used to receive the control unit read identity information request information transmitted by the signal coupling circuit 120, and output the identity information to the following decoding circuit 130; the decoding circuit 130 receives the information output by the identity information unit 140 and performs decoding processing, identifies the identity information therein, and transmits it to the control unit 110.

[0037] The identity information unit 140 provided in the cigarette cartridge 200 is connected to the control unit for bidirectional communication via two IO ports.

[0038] Specifically, the control unit 110 sends a request message for reading identity information through its first IO port IO-1. The information is converted into a sinusoidal wave signal through the signal coupling circuit 120 and transmitted to the IO-1 port of the identity information unit 140. The sinusoidal wave provides energy for the identity information unit 140 to work. At the same time, the identity information unit 140 reads the identity request information from it and generates identity information according to the request. The identity information is transmitted from the IO-1 port to the decoding circuit 130 through the carrier. The decoding circuit 130 deciphers the identity information and transmits it to the second IO port IO-2 of the control unit 110. After receiving the identity information, the control unit 110 performs identity information authentication and comparison.

[0039] The identity information unit 140 can be implemented using an encryption chip. The two ports are IO-1 and IO-2, one for power supply and two-way data communication with the control unit 110, and the other for a common terminal, i.e., ground. There is no difference between the two, and the electrical connection methods can be interchanged. Thus, the identity information unit 140 can achieve identity authentication using only two pins, reducing costs and conserving the already relatively small space in the cigarette cartridge.

[0040] Ginseng Figure 1 、 2 As shown, further, the signal coupling circuit 120 includes a capacitor-resistor charging and discharging circuit, specifically including a first capacitor C1 and a first resistor R1, the first end of the first capacitor C1 is connected to the first IO port of the control unit, the second end of the first capacitor C1 is connected to the first end of the first resistor R1 and the first port of the identity information unit, and the second end of the first resistor R1 is grounded; the signal coupling circuit 120 receives a signal from the first IO port IO-1 of the control unit 110 and couples and transmits it to the IO-1 port of the identity information unit 140.

[0041] Ginseng Figure 1 、 2As shown, further, the decoding circuit 130 includes a detection circuit, specifically including a first diode D1, a first resistor R1, a second capacitor C2 and a second resistor R2, the first end of the first diode D1 is connected to one end of the first resistor R1, the other end of the first resistor is grounded, the second end of the first diode D1 is connected to the first end of the second capacitor C2, the first end of the second resistor R2 and the second IO port of the control unit, the second end of the second capacitor C2 and the second end of the second resistor R2 are grounded; the signal carrying identity information emitted from the IO-1 port of the identity information unit 140 is screened and identified through the detection circuit, and the identity information of the identified identity information unit 140 is transmitted to the second IO port IO-2 of the control unit 110. After receiving the identity information, the control unit 110 performs authentication comparison with the preset identity information.

[0042] Ginseng Figure 1 、 2 As shown, the device further includes a cigarette cartridge heating unit, which is connected to the control unit 110 and is used to control the cigarette cartridge heating switch according to the identity authentication result of the control unit 110; the third IO port IO-3 of the control unit 110 is connected to the cigarette cartridge heating unit, and after the IO-2 port of the control unit 110 receives the identity information of the identity information unit 140, it compares and authenticates it with the preset identity information. After meeting the authentication requirements, the control unit 110 sends a control signal to the cigarette cartridge heating unit through its third IO port IO-3 to control the cigarette cartridge heating unit to turn on the switch for heating.

[0043] Ginseng Figure 1 、 2 As shown, further, the cigarette cartridge heating unit includes a MOS tube Q1 and a heating wire R3 arranged in the cigarette cartridge 200, the switch control end of the MOS tube Q1 is connected to the third IO port of the control unit, the second and third connection ends of the MOS tube Q1 are respectively connected to the positive pole of the power supply and one end of the heating wire R3, and the other end of the heating wire R3 is connected to the negative pole of the power supply; the MOS tube, the battery and the heating wire R3 constitute a loop, the switch control end of the MOS tube is connected to the IO-3 port of the control unit 110, and the control unit 110 controls the connection and disconnection of the loop according to the identity authentication result, thereby controlling the working state of the heating wire R3 in the cigarette cartridge 200.

[0044] Ginseng Figure 1 、 2 As shown, further, the cigarette rod 100 of the electronic cigarette is connected to the cigarette cartridge 200 through three electrical contact points, which are:

[0045] The first electrical contact point is set between the MOS tube Q1 of the cartridge heating unit and the heating wire R3, the second electrical contact point is set between the signal coupling circuit 120 and the IO-1 port connection line of the identity information unit 140, and the third electrical contact point is set between the heating wire R3 of the cartridge heating unit and the ground; because the electronic cigarette cartridge is a consumable and needs to be replaced regularly, the cigarette rod 100 and the cartridge 200 are specifically detachably electrically connected through the above three electrical contact points.

[0046] Ginseng Figure 1 、 2 As shown, further, the second electrical contact point is arranged in the middle, and the first electrical contact point and the third electrical contact point are respectively arranged on both sides of the second electrical contact point, and the positions of the first electrical contact point and the third electrical contact point can be interchanged; the cigarette rod 100 and the cigarette cartridge 200 are detachably connected through three contact points. When the user plugs in and out the cigarette rod and the cigarette cartridge, the plug-in and unplugging positions of the first contact point and the third contact point located on both sides of the connection between the two may be exchanged. This solution fully supports the swapping of the plug-in and unplugging positions of the first electrical contact point and the third electrical contact point, that is, it supports the forward and reverse insertion of the cigarette cartridge and the cigarette rod, thereby increasing user experience and reducing product damage rate.

[0047] Compared with the prior art, the identity information unit in the present application only requires two functional pins for electrical connection. The identity information unit can simultaneously realize power supply and two-way information transmission with the control unit through the two functional pins. The two pins of the identity information unit do not require polarity distinction. Any pin can be used as a common end or a data end, which has the beneficial effects of occupying a small space of the cigarette cartridge, low cost, and high production efficiency; the cigarette cartridge and the cigarette rod support forward and reverse insertion, which increases the convenience of user use.

[0048] Ginseng Figure 1-3 As shown, according to another aspect of the present application, the present application also provides an electronic cigarette identity information authentication method, the method comprising:

[0049] Step S1: The control unit 110 provided in the cigarette rod 100 sends an identity information reading request to the IO-1 port of the identity information unit through the signal coupling circuit 120;

[0050] In step S2, the identity information unit 140 provided in the cigarette cartridge 200 obtains the identity information reading instruction and electric energy through the IO-1 port, and outputs its identity information to the decoding circuit 130 through the IO-1 port. Specifically, in this step, the identity information unit 140 realizes electrical connection and two-way communication with the control unit 110 only through two IO ports. The identity information unit 140 can be realized by an encryption chip. The two IO ports are IO-1 and IO-2 of the identity information unit 140, one of which is used for power supply and two-way data communication with the control unit 110, and the other is connected to the common end, i.e., ground. There is no difference between the two, and the electrical connection method can be interchanged. Thus, the identity information unit 140 can realize the identity authentication function by using only two pins, reducing costs and saving the relatively small space in the cigarette cartridge.

[0051] Step S3, the decoding circuit 130 decodes the identity information of the identity information unit 140 and transmits it to the control unit 110;

[0052] Step S4: the control unit 110 compares and authenticates the identity information received from the identity information unit 140 with the preset identity information;

[0053] In step S5, after the identity authentication information is passed, the control unit 110 controls the cigarette cartridge heating unit provided in the cigarette cartridge to perform heating.

[0054] Specifically, refer to Figure 1 、 2 As shown, since the e-cigarette cartridge is a consumable and needs to be replaced regularly, the cigarette rod 100 and the cigarette cartridge 200 are specifically detachably electrically connected through the three electrical contact points mentioned above. The second electrical contact point is set in the middle, and the first electrical contact point and the third electrical contact point are respectively set on both sides of the second electrical contact point, and the positions of the first electrical contact point and the third electrical contact point can be interchanged; the cigarette rod 100 and the cigarette cartridge 200 are detachably connected through three contact points. When the user plugs in and out the cigarette rod and the cigarette cartridge, the plug-in and unplugging positions of the first contact point and the third contact point on both sides of the connection between the two may be swapped. This solution fully supports the swapping of the plug-in and unplugging positions of the first electrical contact point and the third electrical contact point, that is, it supports the forward and reverse insertion of the cigarette cartridge and the cigarette rod, thereby increasing user experience and reducing product damage rate.

[0055] Compared with the prior art, the identity information unit in the present application only requires two functional pins for electrical connection. The identity information unit can simultaneously realize power supply and two-way information transmission with the control unit through the two functional pins. The two pins of the identity information unit do not require polarity distinction. Any pin can be used as a common end or a data end, which has the beneficial effects of occupying a small space of the cigarette cartridge, low cost, and high production efficiency; the cigarette cartridge and the cigarette rod support forward and reverse insertion, which increases the convenience of user use.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
