detailed description

Embodiment 1, this embodiment is a flue-cured tobacco electronic cigarette, a flue-cured tobacco electronic cigarette, including a battery, a tobacco pot, and a control circuit board. A temperature detection circuit for the temperature of the smoke pot and a vibration circuit that vibrates when the temperature of the smoke pot is detected to reach a set value.

As shown in Figure 1, the temperature detection circuit includes a temperature-sensing probe NTC set on the smoke pot, a standard resistor R4, a capacitor C8, a microprocessor, and a working power supply VDD set on the control circuit board. The working power supply VDD passes through the standard resistor R4 It is connected in series with the temperature sensor NTC, the capacitor C8 is connected in parallel with both ends of the temperature sensor NTC, and the contact between the standard resistance R4 and the temperature sensor NTC is connected to the input terminal of the microprocessor. NTC (Negative Temperature Coefficient) refers to the thermistor phenomenon and material with a negative temperature coefficient that decreases exponentially with increasing temperature. When the temperature rises, the resistance of the temperature sensor NTC will decrease, and the voltage across the capacitor C8 will decrease. When the voltage received by the P0.6 pin of the microprocessor decreases to the set voltage, the smoke will be detected. The temperature on the ceramic heating sheet on the pot has reached the temperature that can smoke cigarettes. Of course, the temperature probe can also use a thermistor with a positive temperature coefficient. Here, when the temperature of the smoke pot rises, the voltage detected by the microprocessor rises. When the set voltage is reached, the smoke pot reaches The set temperature can control the vibration of the vibration motor.

The vibration circuit includes a vibration motor, a microprocessor, a transistor Q1, and a working power supply VDD. The working power supply VDD is connected to the positive terminal of the vibration motor, and the negative terminal of the motor is connected to the collector of the transistor Q1. Microprocessor, when the detection circuit detects that the smoke pot reaches the set temperature, the P4.0 pin of the microprocessor generates an effective signal to turn on the transistor Q1, so that the working voltage VDD supplies power to the vibration motor, and the vibration motor Start vibrating.

The drive circuit includes a switching tube Q2 arranged between the power supply and the anode of the ceramic heating sheet of the smoke pot, the cathode of the ceramic heating sheet is grounded, and the control terminal of the switching tube Q2 is connected to the microprocessor. This embodiment is shown in Figure 1. In the microprocessor The output terminal VDD of the output terminal VDD generates an effective signal, and the drive control module U1 generates an effective signal to control the gate of the MOS transistor Q2 as a switch tube, so that the source-drain of the MOS transistor Q2 is connected, that is, the output terminal of the battery is connected to the The anodes of the ceramic heating sheets are connected, the cathodes of the ceramic heating sheets are grounded to form a loop, and the ceramic heating sheets are electrically heated.

In this embodiment, when the temperature reaches the preset temperature value, the rotation of the centrifugal motor and the timely vibration prompt the consumer to start smoking. There is no need for eyes to observe all the time, and it is also convenient for the visually impaired to use electronic flue-cured cigarettes.

In this embodiment, the NTC temperature-sensing probe is installed on the outer wall of the flue-cured tobacco ceramic heating cup, and wrapped together with high-temperature materials. The NTC temperature sensor detects the temperature change, and its internal resistance changes, forming a change in the sampling voltage value to the A/D conversion circuit inside the MCU. After processing, comparing and calculating by the MCU, the PWM signal that needs to be counted is sent to the MOS tube that controls the output, so that the MOS tube is properly opened and closed, and the packaging temperature is kept constant at the preset temperature value. When the preset temperature is reached, the MCU outputs a level signal to drive the motor to vibrate.
