The consumption statistics of the atomized liquid can be realized by the following methods:
one is to count the consumption of the atomized liquid by directly detecting the reduction of the atomized liquid in the liquid storage cavity of the atomizer through a sensor, such as the reduction of the liquid level.
One is to simulate and count the consumption of the atomized liquid by counting the number of the mouth openings for smoking or absorbing the fog, under normal conditions, a certain amount of atomized liquid is consumed averagely when each mouth of the cigarette is absorbed, and a certain amount of atomized liquid stored in the liquid storage cavity can be absorbed, so that the number of the mouth openings and the consumption of the atomized liquid have a certain proportional relation. Because the starting switch works once every time the smoke is sucked, the number of the opening can be counted by counting the times of starting the switch.
One method is to simulate and count the consumption of the atomized liquid by counting the time length of each smoke suction and the accumulated time length, and under the normal condition, the atomized liquid consumed in a certain time length is basically the same, so that the time length of the starting switch, namely the time length of the smoke suction, has a certain proportional relation with the consumption of the atomized liquid.

The preset total consumption amount of the atomized liquid is equal to the total amount of the atomized liquid which can be stored in one atomizer, so that when a user consumes all the atomized liquid in one atomizer, the atomized liquid cannot be used even if the atomized liquid is injected again privately. The preset value is set according to the components of the atomized liquid, the volume in the liquid storage cavity and the statistical value of the loss of the atomized liquid during the time of mist suction or mist suction of each port.

The electronic atomization device for preventing repeated liquid injection use of claim 9, wherein the read-write control module comprises a resistor R2 and a MOS transistor Q1, one end of the resistor R2 is connected to the gate G of the MOS transistor Q1 and a PWM-OUT/WR/RD signal terminal, the other end of the resistor R2 is connected to the source S of the MOS transistor Q1, and the drain D of the MOS transistor Q1 is connected to a GND ground signal terminal.
11. A control method of an electronic atomization device for preventing repeated liquid injection use is characterized by comprising the following steps:
s10, setting and initializing atomizer parameters;
s20, detecting the resistance value of the atomization resistor by the microcontroller;
s30, the microcontroller judges whether the atomizer is connected or not by detecting the resistance value of the atomizing resistor, if not, the circular detection is continued, and if yes, the next step is carried out;
s40, the microcontroller reads the identification code in the identification code storage module, judges whether the identification code is correct, if not, confirms that the atomizer is forged and enters the step S80, if so, confirms that the atomizer is a genuine product and enters the next step;
s50, the microcontroller detects the starting switch and judges whether the starting switch is in a working state, if not, the standby cycle detection is carried out, if yes, the atomizer enters the working state and enters the next step;
s60, the atomized liquid consumption statistical module works, the atomized liquid consumption is calculated in a simulation mode, and the atomized liquid consumption is accumulated to the accumulated number storage module in the ID chip through the microcontroller 1;
s70, the microcontroller reads the cumulative number of the consumption of the atomized liquid in the cumulative number storage module, judges whether the cumulative number of the consumption of the atomized liquid exceeds the preset total consumption of the atomized liquid, if not, the step S50 is returned, and if yes, the next step is carried out;
and S80, turning off the output of the power control module and forbidding the atomizer to be used continuously.
