Wherein, man-machine interaction part is used to trigger control instruction, the control instruction include charging instruction, heating instructions,
Parameter setting, measure voltage ＆ current etc. are instructed.When implementing, as shown in Fig. 2 man-machine interaction part can be display screen, touch
The functional unit such as screen or button.
For example, being controlled the triggering of instruction by the display screen or touch screen of intelligent kettle, user is facilitated to pass through
Display screen or touch screen flexibly set charge mode or heating mode, or voluntarily set charging, heating parameters etc., and will touch
The control instruction of hair is sent to chip microcontroller and intelligent kettle is controlled.
In another example, the triggering of instruction is controlled by the button of intelligent kettle, facilitates user flexible by button
Charge mode or heating mode are set, or charging heating parameter etc. is voluntarily set, and the control instruction of triggering is sent to
Chip microcontroller is controlled to intelligent kettle.
Wherein, wireless transmit/receive units are used to realize the wireless data transceiving between single-chip microcomputer and mobile terminal, specifically include
The control instruction that mobile terminal is initiated sends single-chip microcomputer, and charging and heating parameters that single-chip microcomputer is exported are sent to movement
Terminal；
For example, being controlled touching for instruction by the application interface (such as long-range kettle controls application program) of mobile terminal
Hair, the control instruction of triggering is sent to intelligent kettle, the wireless receipts of intelligent kettle by the wireless transmit/receive units of mobile terminal

First control end of one switch, the first common port of control is connected with first choice end so that wireless charging receives managing chip
DC signal after rectification carries out wireless charging by charging management chip to battery, meanwhile, charging management chip is according to list
The charging instruction that piece machine is sent, carries out the work such as detecting, single-chip microcomputer is fed back in charging complete to charging voltage, electric current, with
Just single-chip microcomputer the first common port of cut-out and connection at first choice end in time in charging complete, it is to avoid overcharged to battery,
Protect the security of battery charging and the service life of battery.
Wherein, fourth selection end (see S4 in Fig. 2) of the battery respectively with charging management chip and second switch is connected, profit
The DC signal transmitted with charging management chip carries out charging work, and provides electric energy progress heater for heating unit
Make.
For example, user by touch screen by having sent out heating mode (i.e. heating instructions), it is assumed that wireless charging connects under present case
When take-up circle can't detect the AC energy signal that wireless transmission coil is transmitted by electromagnetic induction, single-chip microcomputer is according to heating instructions
By the second control end of second switch, the second common port of control is connected with the 4th selection end, the electric energy discharged using battery
Electric energy, which is provided, for heating unit carries out heating work.Therefore, when the power supply or wireless current signal without physical connection,
The electric energy that can be provided at any time using kettle battery carries out heating work, improves the service efficiency of intelligent kettle.
As shown in Fig. 2 in the embodiment of the present invention, heating unit includes heat sensor, heating managing chip and heater block
(such as heating coil or heating plate), heat sensor is connected with single-chip microcomputer, heating managing chip respectively with single-chip microcomputer, heater block and
The second common port connection of second switch；
Wherein, heating managing chip is used for the heating management work of heater block, including is entered according to the attribute of heater block
The control of the setting of row heating parameters, heating-up temperature and time and/or Thermal protection etc., the heating parameters include but is not limited to add
Hot temperature and heat time；Heat sensor is used for detection temperature, and the temperature detected is sent into control unit.
For example, user triggers heating mode (i.e. heating instructions) by button, and assume wireless charging under present case
When receiving coil can't detect the AC energy signal that wireless transmission coil is transmitted by electromagnetic induction, single-chip microcomputer refers to according to heating
Order is by the second control end of second switch, and the second common port of control is connected with the 4th selection end, is heating part using battery
Part provides electric energy and carries out heating work, meanwhile, heating managing chip can also carry out heating parameters according to the attribute of heater block
Setting, such as when the attribute of heater block is fast for firing rate, can correspondingly reduce the heat time, when user's triggering heating refers to
Heating-up temperature is also provided with when order, then carries temperature parameter in heating instructions, heating managing chip can also be according to adding
The temperature parameter carried in heat instruction carries out the setting and monitoring of heating-up temperature, passes through when heating-up temperature reaches the temperature of setting
Heat sensor feeds back to single-chip microcomputer in time so that single-chip microcomputer cuts off the second common port in time by the second control end of second switch
With the 4th selection end connection, so as to reduce battery consumption.
