The specific embodiment

For clearly demonstrating the scheme in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.

Referring to Fig. 1, the schematic diagram of this intelligent temperature control electric kettle comprises: have the panel 4 of displays temperature on kettle body 1, the chassis 8 that the intelligent temperature control circuit is installed, the chassis 8 and set, regulate switch 2, switch 3 and the switch 5 of temperature to switch 7.

The user is provided with the required number of degrees by the switch of setting, regulate temperature, and the intelligent temperature control circuit receives the water in the heating kettle body 1 behind the signal that the user is provided with in the chassis 8.

Wherein, built-in intelligent temperature control circuit comprises as shown in Figure 2: the power supply input circuit of power supply is provided, after the electric current process rectification circuit rectification that power supply input circuit provides, enters CPU, CPU receives the signal from temperature sensor, and shows on display screen;

The user by external setting-up, regulate key circuit that switch 2, switch 3 and switch 5 to the switch 7 of temperature is connected and realize that the selection of temperature regulates and setting, after CPU receives the temperature signal of adjusting, setting, be presented on the LCD (LCD) by connecting drive circuit; Trigger the electronic switching circuit that connects by the control circuit that connects, electronic switching circuit triggers the temperature controller conducting, realizes that heater heats, and breaks down under big electric current for avoiding heater, and temperature controller also is connected with fuse.

Describe the structure of intelligent temperature control circuit above in detail, describe the physical circuit of various piece below in conjunction with accompanying drawing in detail and form.

Referring to Fig. 3, Fig. 3 is the pin configuration figure of process chip CPU, and each control and display circuit interconnect by the pin of CPU; The switch of user by peripheral hardware realized the adjusting to temperature, key circuit as shown in Figure 4, the switch (SW1 to SW5) on the key circuit, LED (LED1 to LED5) are connected with corresponding pin on the CPU; SW1 to SW5 is respectively power supply and controls, adds thermal control, preservation and controlling, temperature increase control, temperature reduction control.

In the adjustment control procedure, CPU shows the temperature value of being regulated by LCD drive circuit and the LCD circuit that connects, and as Fig. 5, shown in Figure 6, is connected by corresponding pin on LCD drive circuit and the LCD circuit.

CPU also connects the base stage of triode Q1 as shown in Figure 7 by pin 2, when connecting power supply, realize the demonstration backlight of display screen.
