[0011] Another object of the present invention is to provide an atomizer matched with an electronic cigarette body, wherein the atomizer includes the atomizer system.

[0012] Another object of the present invention is to provide a method for matching an atomizer with an electronic cigarette body, wherein the atomizer includes the atomizer system, and the atomizer matching method includes the following steps:

[0013] Step S1: When the atomizer is inserted into the interface of the electronic cigarette body, since the battery part of the electronic cigarette body is in sleep mode, and since a pull-down resistor R1 is externally connected to the 4-pin of the contact electronic P3, the communication SI / O port level of the electronic cigarette body can be pulled down at this time to achieve the function of waking up the battery of the electronic cigarette body;

[0014] Step S2: After waking up, the VBAT of the battery of the electronic cigarette body provides power, and the power reaches the main control MCUU1 of the atomizer through the 1st pin of the contact terminal P3 for system power supply. At this time, the 2nd pin connected to the contact terminal P3 is the SI / O port of the atomizer. At this time, it is in the output state and outputs the standardized protocol data signal code. The SI / O port of the electronic cigarette body connected to the 2nd pin of the contact terminal P3 is in the input state and detects the data signal code sent by the atomizer.

[0015] Step S3: The MCU of the electronic cigarette body sets a timeout detection.

At this time, the power supply of the electronic cigarette body will be disconnected, and it is considered to be an unmatched atomizer. The electronic cigarette body enters sleep. If the MCU of the electronic cigarette body detects that the data signal code sent by the atomizer is in accordance with the specified protocol data, the electronic cigarette body verifies that the atomizer has passed and continues to supply power;

[0016] Step S4: After the 4 pins of the main control MCUU1 of the atomizer send data to the electronic cigarette body, the 4 pins of the main control MCUU1 serve as an input port to detect and judge the protocol signal of the electronic cigarette body. At this time, the SI / O port of the electronic cigarette body connected to the 2 pins of the contact terminal P3 serves as an output signal port to output the signal protocol. The 4 pins of the main control MCUU1 of the atomizer judge the protocol signal sent by the electronic cigarette body. If it meets the specified requirements, the 6 pins of the main control MCUU1 of the atomizer drive the field effect tube Q1 to turn on the field effect tube Q1, thereby heating the heating wire L1. If the 4 pins of the main control MCUU1 of the atomizer judge that the protocol signal sent by the electronic cigarette body fails to be verified, the 6 pins of the main control MCUU1 at the atomizer do not drive the field effect tube Q1, so that the field effect tube Q1 is not turned on, thereby achieving the heating of the heating wire L1.

[0017] The beneficial effects of the present invention are as follows: through this atomizer system, it can be ensured that the communication level between the electronic cigarette atomizer and the electronic cigarette body is not fluctuated by the load, and stable level communication is achieved. In addition, the electronic cigarette body recognizes the electronic cigarette atomizer, and at the same time, the electronic cigarette atomizer recognizes the electronic cigarette body. The dual authentication relationship is achieved, and the same brand is specially matched. This system has a simple structure, low cost, and also achieves the encryption effect.

[0023] like Figure 3 A method for matching an atomizer with an electronic cigarette body is shown, wherein the atomizer includes the atomizer system, and the atomizer matching method includes the following steps:

[0024] Step S1: When the atomizer is inserted into the interface of the electronic cigarette body, since the battery part of the electronic cigarette body is in sleep mode, and since a pull-down resistor R1 is externally connected to the 4-pin of the contact electronic P3, the communication SI / O port level of the electronic cigarette body can be pulled down at this time to achieve the function of waking up the battery of the electronic cigarette body;

[0025] Step S2: After waking up, the VBAT of the battery of the electronic cigarette body provides power, and the power reaches the main control MCUU1 of the atomizer through the 1-pin of the contact terminal P3 for system power supply. At this time, the 2-pin connected to the contact terminal P3 is the SI / O port of the atomizer. At this time, it is in the output state and outputs the standardized protocol data signal code. The SI / O port of the electronic cigarette body connected to the 2-pin of the contact terminal P3 is in the input state at this time, and the data signal code sent by the atomizer is detected. The MCU of the electronic cigarette body sets a timeout detection. If no data or data error of the atomizer is detected within the time specified by the protocol, it is considered to be a timeout. At this time, the power supply of the electronic cigarette body will be disconnected, and it is considered to be an unmatched atomizer. The electronic cigarette body enters sleep. If the MCU of the electronic cigarette body detects that the data signal code sent by the atomizer is in compliance with the specified protocol data, the electronic cigarette body verifies that the atomizer has passed and continues to supply power;

[0026] Step S4: After the 4 pins of the main control MCUU1 of the atomizer send data to the electronic cigarette body, the 4 pins of the main control MCUU1 serve as input ports to detect and judge the protocol signal of the electronic cigarette body, and at this time, the SI / O port of the electronic cigarette body connected to the 2 pins of the contact terminal P3 serves as an output signal port to output the signal protocol. The 4 pins of the main control MCUU1 of the atomizer judge the protocol signal sent by the electronic cigarette body for judgment. If it meets the prescribed requirements, the 6 pins of the main control MCUU1 of the atomizer drive the field effect tube Q1 to turn on the field effect tube Q1, forming heating of the heating wire L1, and achieving the purpose of two-way verification and two-way control. If the 4 pins of the main control MCUU1 of the atomizer judge that the protocol signal sent by the electronic cigarette body fails to be verified, the 6 pins of the main control MCUU1 at the atomizer do not drive the field effect tube Q1, so that the field effect tube Q1 is not turned on, thereby achieving the heating of the heating wire L1.
