[0038] The following is combined Figure 2 Explanation of the working principle of the cigarette butt detection component in this embodiment:

[0039] The pulse generation unit 31 generates a pulse signal and drives two parallel infrared emitting diodes IR1 and IR3 to emit infrared light by controlling the first switching transistor Q3, while providing a clock signal to the second D flip-flop U1A.

[0040] When a cigarette butt is inserted into the inlet, it reflects the infrared light emitted by infrared emitters IR1 and IR3 to infrared receiver IR2, which generates a weak electrical signal. As the cigarette butt approaches infrared emitters IR1 and IR3 and infrared receiver IR2, the electrical signal generated by infrared receiver IR2 gradually strengthens. When a certain signal strength is reached, a low-level pulse signal is generated. This pulse signal is amplified by the first amplification unit 41, filtered by the filtering unit 42 to remove interference signals, and then amplified by the second amplification unit 43 before being sent to the second D flip-flop U1A. The second D flip-flop U1A latches the amplified low-level signal when the rising edge of the first D flip-flop U1B arrives, thus turning on the fifth switch Q5. After the fifth switch Q5 turns on, current flows through the light-emitting diode LED1, which lights up to indicate that a cigarette butt has been detected. At the same time, the sixth switch Q2 turns on, and the collector of the sixth switch Q2 outputs a low-level signal through interface J1.
