The automatic soymilk machine circuit is shown in the figure. The working principle is as follows: after adding an appropriate amount of water to the machine, the power is turned on, and the circuit reset is cleared. The pins 11, 12 and 13 of IC2 are all "O", the output of pin 10 is "1", the switch tube V1 is turned on, the J2 is electrically closed, and the heating tube starts to heat up. At this time, the 3, 4 pins of IC2 and the 13 pins of IC3 are all "0". The clock CP signal oscillator composed of the two NAND gates and timing elements R14 and C2 works, generating a signal with a period of 0.21 seconds to IC4. 11 feet, IC4 is divided on the basis of the signal, its 2-pin 13-divided output is low and the high period is 29 minutes pulse signal, and the rising edge after 14.5 minutes is used to end the whole process and humming prompt . The 6-pin of IC4 is a pulse signal with a divide-by-7 output period of 27 seconds, which is used to trigger the drive motor. Its 15 feet are divided by 10, the output period is 3.6 minutes pulse, the first 1.8 minutes of low level half cycle is allowed to beat 4 times, and after 1.8 minutes, the rising edge will lock IC4's 4 feet in the “0†state, so that V2 is cut off. End the beating process and maintain heating. When the soy milk is heated and boiled, the overflow switch K is closed, and the 9th leg of the ICI changes from "1" to "O", and the circuit stops heating. When the boiled soymilk drops to break K, the soymilk is heated again, which is designed to effectively kill the harmful aflatoxin in the soy milk.
