Embodiment 1
[0027] Such as figure 1 As shown, the integrated cigarette lighting circuit is mainly composed of a resistance wire RT for heating and lighting a cigarette, a control circuit connected to the resistance wire RT, a trigger circuit for providing a control signal to the control circuit, and a control circuit and a trigger circuit respectively. It consists of a power supply circuit that is connected to and supplies power to the circuit.
[0028] Wherein, the control circuit is used to provide working current and voltage to the resistance wire RT, which is composed of a control chip U2, a capacitor C1 and a capacitor C2. In order to ensure the actual use effect, the control chip U2 is preferably realized by an integrated chip with a model number of S090D.
[0029] When connecting, one end of the capacitor C1 is connected to the VDD pin of the control chip U2, and the other end is connected to the GND pin of the control chip U2, while one end of the capacitor C2 is connected to the...
Embodiment 2
[0048] The difference between this embodiment and Embodiment 1 is that the control chip U1 is further connected with a three-terminal common-anode diode P5.
[0049] Pin 3 of the three-terminal common anode diode P5 is connected to pin 4 of the control chip U1 through a resistor R4, pin 2 of the three-terminal common anode diode P5 is connected to the VDD pin of the control chip U2, and the three-terminal common anode Pin 1 of the diode P5 is connected to pin 5 of the control chip U1 through the resistor R5.
[0050] The function of the three-terminal common anode diode is to convey the different working states of the circuit through the indicator lights of different colors, and to respond to the specific operation of the circuit through the light effect, so that the user can better grasp the specific operation of the circuit state. The three-terminal common-anode diode is a conventional product in the field, and those skilled in the art can complete the installation and use ...
Embodiment 3
[0055] The difference between this embodiment and Embodiment 2 is that the control chip U1 is also connected with an auxiliary ignition circuit; the auxiliary ignition circuit consists of a fan P6 and a transistor Q1 connected in series between the base and the emitter of the transistor Q1 Resistor R7, and resistor R6 with one end connected to the base of the transistor Q1 and the other end connected to the pin 1 of the control chip U1; wherein, the emitter of the transistor Q1 is grounded, and the collector of the transistor Q1 is connected to the 2 pin of the fan P6. The pins are connected, and pin 1 of the fan P6 is connected to the connection point of the resistor R2 and the resistor R3.
[0056] The infrared receiving diode D2 and the infrared emitting diode D3 continue to judge whether there is smoke and need to be ignited. When there is smoke, the pin 2 of the control chip U1 becomes high level, otherwise it is low level; 2 When it becomes high level, the pin 5 changes ...
