The detection plate is located one side of the reminder main body and is in an inclined plane shape, and the detection plate is mainly composed of two Hall switches. The magnet is a small ultrathin sheet magnet, is adhered or fixed at the bottom of the end of the kettle switch, cannot influence the function and operation of the kettle switch due to extremely light weight, and meanwhile has certain hiding property and attractiveness, and the magnet cannot be touched when the kettle switch is pressed by a finger. The below of kettle switch is arranged in to the reminiscences main part to keep certain interval, the pick-up plate is located the below of magnet promptly, thereby can make the kettle switch directly get into the detection zone of pick-up plate top, when the kettle switch was pressed to the finger, also can not touch the pick-up plate.

The Hall switch is a common magnetic sensing element, has the characteristics of small volume, light weight, low power consumption and convenient installation, and has the characteristic that when a magnetic object is close to the Hall switch, the Hall switch can output a low-level digital signal, and when the magnetic object is far away from the Hall switch, the Hall switch can output a high-level digital signal. When the kettle switch is pressed down to be electrified and boiled, the kettle switch is changed into an inclined state from a horizontal state, at the moment, the magnet piece at the tail end of the kettle switch is closest to the detection board, then the two Hall switches in the detection board all output low level signals, otherwise, when the kettle switch jumps to be powered off, the kettle switch is changed into the horizontal state from the inclined state, the magnet piece is farthest from the detection board, and then the two Hall switches in the detection board all output high level signals.

The two Hall switches are respectively connected with two input ends of the single chip microcomputer module, one of the input ends is a wake-up input end, generally, the single chip microcomputer with the functions of dormancy and wake-up can be triggered and woken up by low level (high level is invalid). When the kettle switch is pressed down and powered on to boil water, the Hall switch in the detection board outputs a low level signal, the single chip microcomputer module in the dormant working mode is converted into a normal working mode through awakening the input end, the low level signal output by the other Hall switch is sent to a CPU (central processing unit) of the single chip microcomputer module through the other input end, and the CPU does not act. When water is boiled, the kettle switches jump to be powered off, the two Hall switches both output high-level signals, the high-level signals are sent to a CPU through the input end of the single chip microcomputer module, the CPU generates actions and sends instructions to a timer in the single chip microcomputer to start timing, when a preset time (delay standing time after water is boiled) is reached, the output end of the single chip microcomputer module outputs a high-level signal to the buzzer to enable the buzzer to send out a sound reminding signal, meanwhile, the CPU sends instructions to the timer again to start timing, when the preset time (delay time of sounding of the buzzer) is reached, the output signal of the single chip microcomputer module stops, the buzzer stops sounding, finally, the CPU sends a sleep instruction to the power management register, the single chip microcomputer module is converted into a sleep working mode, and is awakened again when water is boiled next time.

The key module and the display module are used for setting relevant parameters of the singlechip module, such as the delay standing time after water is boiled and the delay time of sounding of the sounder.

The utility model has the advantages that:

can make current electric kettle, possess more practical and humanized water boiling sound and remind the function, can let after the water is boiled, certain time stews, sends out sound warning signal again, can not only let the user drink more healthy boiling water, and operating mode is convenient more, swift moreover.
