A liquid heating vessel according to claim 8, further comprising a heating part (34) and a control assembly, wherein the control assembly comprises a magnetic member (341a), a magnetic fitting (25) and a switch (342), the switch (342) is used for controlling the heating part (34), the magnetic fitting (25) is arranged on the second cover body (2), and the magnetic member (341a) and the switch (342) are arranged on the vessel body (3);

when the second cover body (2) is covered on the container body (3), the magnetic element (341a) is not matched with the magnetic matching piece (25) so as to disconnect the switch (342);

when the second cover body (2) is taken off from the container body (3), the switch (342) can be opened under the action of the magnetic force between the magnetic member (341a) and the magnetic matching piece (25).

10. A liquid heating vessel according to claim 9, wherein said control assembly further comprises a moving portion (341) provided to said vessel body (3), said magnetic member (341a) being provided to said moving portion (341), said moving portion (341) being rotatable with respect to said vessel body (3);

when the second cover body (2) is removed from the container body (3), the moving part (341) can rotate under the action of the magnetic force of the magnetic element (341a) and the magnetic matching piece (25) so as to open the switch (342);

when the magnetic force between the magnetic member (341a) and the magnetic mating member (25) disappears, the moving part (341) can be reset to open the switch (342).
