6. After the whole suspension delay work of the hand washing machine is finished, the MCU controller transmits a trigger signal to the electromagnetic valve to trigger the electromagnetic valve to work for the second time and open the water supply pipe 22, so that the water is discharged from the water supply pipe 22 to the hand, and the hand washing machine is convenient to wash.

7. After the hand washing is finished, the electromagnetic valve controller transmits a working closing signal to the MCU controller, the MCU controller transmits a trigger signal to the circuit of the paper outlet machine 43, the paper outlet machine 43 works to flow a certain amount of paper towels out of the paper outlet 44 of the box body 4, and finally the paper towels are cut off so that a user can wipe hands after washing hands.

8. After hand washing and hand wiping are finished, the illuminating lamp is turned off in a prolonged way after the internal delay of the MUC controller, data is stored and memorized after five seconds of delay, and then the hand washing machine integrally enters a standby state to wait for the next triggering.

The embodiment of the present invention is not limited to this, according to the above-mentioned content of the present invention, the common technical knowledge and the conventional means in the field are utilized, without departing from the basic technical idea of the present invention, the present invention can also make other modifications, replacements or combinations in various forms, all falling within the protection scope of the present invention.
