Embodiment Construction
[0008] Now, the present invention will be described in detail in conjunction with the embodiments shown in the accompanying drawings.
[0009] Such as figure 1 As shown, an intermittent heating and stirring device includes a shell 1 and a material container 2, and its control working circuit is as follows figure 2 As shown, it is composed of a clock integrated circuit IC, a charging and discharging capacitor C1, a control relay J, a stirring motor M with stirring blades, and a heating tube L. Among them, the IC is NE555, and the 2 pins of the IC are connected in series with a diode VD2 and an adjustable resistor RP2. The other end of RP2 is connected to one end of resistor R2 with the active end, and the other end of R2 is connected to pin 7 of IC, the positive pole of diode VD1, and one end of resistor R1, and the other end of R1 is connected to adjustable resistor RP1 in series, and the other end of RP1 and the active end are connected to pin 8 of IC in parallel. 4 pins, p...
