Referring to Fig. 1 and Fig. 2, the hot drink fast cooling device in the utility model, including sink 1, cooling tube 2, single-chip microcontroller
3, DC MOTOR CONTROL module 4, setting keyboard 5 and liquid crystal display 6, cooling tube 2 is the Vertical U-Shaped Tubes outside sink 1, cold
But the both ends nozzle of pipe 2 is located in sink 1, and U-tube is equipped with temperature sensor 7 and water pump 8, water pump 8 and DC MOTOR CONTROL
Module 4 is connect after connecting with single-chip microcontroller 3, and temperature sensor 7, setting keyboard 5 and liquid crystal display 6 are connect with single-chip microcontroller 3 respectively.
Temperature sensor 7 is made of the thermistor and watertight transducer of model NTC.Thermistor can be according to temperature not
With resistance value is changed, upon power-up, by transmitting temperature information in the form of a voltage with 3 connected port of single-chip microcontroller.
Single-chip microcontroller 3 is 89C51 single-chip microcontroller 3, the model L298N motor drive module of DC MOTOR CONTROL module 4.For
MCU minimum system becomes digital signal for receiving after the information to come is handled to temperature sensor 7 and setting keyboard 5
Pass to the DC MOTOR CONTROL module 4 and LCD liquid crystal display screen 6 of control water pump 8.
Water pump 8 further includes its peripheral unit of direct current generator, is connected with L298N delivery outlet, the voltage value inputted by L298N
Change revolving speed.
Referring to Fig. 3, DC MOTOR CONTROL module 4 is made of L298N motor drive module and its peripheral circuit.With single-chip microcontroller
3I/O mouthfuls are connected, and the PWM inputted by 3I/O mouthfuls of single-chip microcontroller is converted to the voltage value of output, voltage is supplied direct current generator.
The power supply of whole device turns 5V power panel by AC-DC isolated power supply 220V and its external circuit forms.220V is handed over
