The electric kettle as claimed in claim 2, wherein said switch module comprises a first control switch and a second control switch, said first control switch and said second control switch being connected in series between a power source and ground, said water pump being connected between said first control switch and said second control switch, a control end of said first control switch being connected to said controller, a control end of said second control switch being connected to said kettle body condition detecting means.
4. An electric kettle according to claim 3, wherein the kettle body state detecting means outputs an opening control signal for controlling the opening of the second control switch in the non-activated state, and the water supply leakage signal outputted from the kettle body state detecting means in the activated state activates the closing of the second control switch.
5. The electric kettle as claimed in any one of claims 1 to 4, wherein said kettle body state detecting means comprises a body sensing assembly provided on a handle of said kettle body.
6. The electric kettle as claimed in claim 5, wherein,
the human body induction component is fixedly arranged on the inner side of the handle and covers at least part of the area on the inner side of the handle; and/or the human body induction component is arranged outside the handle and covers at least part of the top outside the handle.
7. The electric kettle as claimed in claim 5, wherein the handle has a mounting slot for the body sensing assembly, and the body sensing assembly is mounted in the mounting slot by a snap fit.
8. The electric kettle of claim 5, wherein the body sensing assembly comprises at least one of a capacitive touch assembly, a resistive touch assembly, and at least one photosensor.
9. The electric kettle as claimed in any one of claims 1 to 4, wherein said kettle body state detecting means comprises an attitude sensor connected to said controller and mounted on said kettle body for detecting an inclination angle and/or an acceleration of said kettle body.
10. The electric kettle as claimed in any one of claims 1 to 4, further comprising a base, said base being connected to said kettle body via a coupler, said kettle body state detecting means comprising a contact resistance detecting circuit for detecting a contact resistance between said base and said kettle body; and outputting the water supply leakage signal under the triggering of the change of the contact resistance.
