Embodiment Construction
[0010] Follow the instructions below figure 1 With the description of the drawings, the related technology of the present invention will be further described by taking the water dispenser control device with health care function as an example.
[0011] Selection of components and their technical parameters
[0012] D1 and D2 are Φ5mm high-brightness light-emitting diodes, and the colors of the light-emitting diodes are green and red respectively;
[0013] D3~D6 are silicon rectifier diodes, the model can be 1N4004 or 1N4007;
[0014] R1, R2, R3 are step-down current limiting resistors, R1, R2 use 1 / 4W ~ 1 / 2W carbon film resistors or metal film resistors, R1, R2 resistance is 150KΩ, R3 uses 2W metal film resistors, the resistance is 32KΩ;
[0015] C1 is a 12V DC power supply filter capacitor, using a 470μF / 25V aluminum shell electrolytic capacitor;
[0016] JRX-13F 12V DC relay, in order to prevent excessive power consumption on the drop-down resistor R3, the pick-up curren...
