The output end of the inverter 1 is coupled to the input end of the 555 time base chip 1. The switch circuit 14 includes a transistor switch 1. The base of the transistor switch 1 is connected to the base of the 555 time base chip 1. The output end of one is coupled, the collector of the transistor switch one is connected to power, the emitter of the transistor switch one is connected in series with the hair dryer 15 and then grounded, the voltage comparison circuit 10 includes a voltage comparator, the delay circuit 16 includes an RC delay circuit, the timing circuit two 17 includes an inverter two and a 555 time base chip two, the output end of the inverter two is coupled to the input end of the 555 time base chip two, the switch circuit two 18 includes a transistor switch two, the base of the transistor switch two is coupled to the output end of the 555 time base chip two, the collector of the transistor switch two is connected to power, and the emitter of the transistor switch two is connected in series with the negative pressure fan 19 and then grounded.

[0038] The push button switch 12 is fixedly connected to the workbench 1; the input end of the controller 11 is electrically connected through the push button switch 12; the input end of the timing circuit 13 is coupled to the output end of the controller 11, and the timing circuit 13 starts timing in response to the control signal output by the controller 11 and outputs a timing signal 1 within the timing time; the controlled end of the switch circuit 14 is coupled to the output end of the timing circuit 13, and the switch circuit 14 controls the hair dryer 15 to be powered on and work in response to the timing signal 1.

The input end of the voltage comparison circuit 10 is coupled to the output end of the dust sensor 9, and the output end of the voltage comparison circuit 10 is coupled to the input end of the controller 11. The voltage comparison circuit 10 receives the dust signal and outputs a comparison signal to the controller 11 after it is greater than a preset dust reference signal.

[0039] When the processing chamber of the present invention is opened normally, the main door 4 is opened to open the processing chamber. If it is necessary to polish the wooden toys, the main door 4 is rotated to cover the processing chamber, and then the auxiliary door 7 is slid between the slide rails 6 to open the opening 5, so that the operator can put his hand into the processing chamber to process the wooden toys, and the wood chips flying after processing can be retained in the processing chamber as much as possible. When the processing is completed and the wood chips in the processing chamber need to be cleaned, the auxiliary door 7 is slid to cover the opening 5, and then the button switch 12 is pressed, so that a high-level signal is input to the input end of the controller 11. At this time, the controller 11 will output a control signal to the timing circuit 13. The timing circuit 13 starts timing in response to the control signal and outputs a timing signal to the base of the switch circuit 14 within the timing time. At this time, the emitter and collector of the switch circuit 14 are turned on, so that the hair dryer 15 is energized and starts working. External air is blown into the processing chamber, so that the wood chips are lifted up in the processing chamber and no longer adhere to the inner bottom surface of the processing chamber. At this time, the dust sensor 9 can detect the dust density in the processing chamber and output a dust signal to the voltage comparison circuit 10. The voltage comparison circuit 10 compares the dust signal with the preset dust reference signal. If it is determined that the dust signal is greater than the reference signal, the comparison signal is output to the controller 11. After receiving the comparison signal, the controller 11 outputs a control signal to the delay circuit 16. The capacitor in the delay circuit 16 is charged, and a high-level delay signal is output after the charging is completed, thereby completing the action of outputting the delay signal after the timing ends. The timing circuit 2 17 starts timing in response to the delay signal and outputs the timing signal 2 to the base of the switch circuit 2 18 within the timing time. At this time, the collector and emitter of the switch circuit 2 18 are turned on, so that the negative pressure fan 19 can start working, and the lifted wood chips are extracted through the air holes 8. Finally, they are collected after passing through the dust removal bag, thereby ensuring that the processing chamber is clean.
