Detailed ways

The gist of the utility model is to overcome the deficiencies of the prior art, and provide an induction cooker with a breathing lamp. The breathing lamp is added to the induction cooker, and the user can observe the use status more intuitively, and the cost is lower, the performance is stable and reliable, and the It improves the viewing experience of users and brings more experience to users. The following will be described in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present utility model.

The principle diagram of the present utility model is as shown in Figure 1, a kind of induction cooker with breathing lamp, comprises furnace body 2, furnace surface 1 and control panel 5, and described furnace surface 1 is installed on the surface of furnace body 2, and control panel 5 Installed on the furnace body 2 through the connecting structure 6, the control board 5 includes the control button 3 and the LED indicator 4, the LED indicator 4 is welded on the LED indicating circuit, and the LED indicator 4 achieves the effect of the breathing light through the control of the LED indicating circuit .

The structural diagram of the LED indicating circuit of the present utility model is shown in Figure 2. The LED indicating circuit is arranged on the PCB circuit board, and the circuit is composed of a pull-up resistor R1, LED, switch circuit and MCU circuit which are electrically connected to each other in sequence. The diode and the switch circuit are composed of resistor R2 and power amplifier Q1 connected in parallel. One end of the pull-up resistor R1 is connected to the positive pole of the power supply VCC, the other end is connected to the negative pole of the LED, one of the positive poles of the LED is connected to the resistor R2, the other is connected to the emitter of the power amplifier Q1, the collector of Q1 is grounded, and the base is connected to the output port P1 of the MCU connected. The LED is the LED indicator light 4, and there are multiple LEDs, which are distributed in different positions according to different functions.

Under normal circumstances, when the P1 port of the MCU outputs a high level, the LED light is off, and when the MCU outputs a low level, the LED light is on. In the operation of this circuit, the MCU provides a continuous square wave signal to the P1 output port. At this time, the LED light will appear in two alternate states of continuous on and off. When the frequency of the square wave signal is high, the LED light is blocked due to visual residual factors. The on-off state of the wave pulse control cannot be recognized by the human eye, so by controlling the frequency of the square wave pulse at the P1 output port, the effect of slowly brightening or dimming the breathing light can be achieved. The frequency of the square wave waveform at the output port of P1 is stable during operation, but the operating frequency can be preset, and the duty ratio of the output waveform is variable, and the switch circuit composed of Q1 and resistor R2 in parallel can adjust the square wave pulse. frequency and duty cycle.
