The number of the water receiving sub-grooves is not limited to two, but also is not limited to a semi-annular shape. The water receiving tank 2 can also be an integer, for example, the kettle body 1 can be including the upper kettle body that is located the storage tank 11 upside and be located the lower kettle body of storage tank 11 downside, and upper kettle body and lower kettle body pass through bolt sealing connection, when needs dismantlement water receiving tank 2, can rotate the upper kettle body and move for lower kettle body to take out water receiving tank 2 along upper and lower direction, can take out water receiving tank 2 through dismantling upper kettle body and lower kettle body installation water receiving tank 2 in the same way.

For convenient dismantlement of water receiving sub-groove, as shown in fig. 4, the juncture of water receiving sub-groove's lateral wall and terminal surface is sunken setting to be formed with the clearance 7 of stepping down between two adjacent water receiving sub-grooves. Especially under the condition that two adjacent water receiving sub-grooves are mutually clamped or connected through magnetic force, the split groove 7 is arranged so that the user can conveniently extend fingers into the split groove to detach the water receiving sub-grooves.

In order to prevent the water in the water receiving sub-grooves from spilling out due to the movement of the water receiving sub-grooves relative to the kettle body 1 in the use process of the kettle, the adjacent two water receiving sub-grooves are mutually clamped or mutually connected through magnetic force. For example, the connection part of two adjacent water receiving sub-grooves can be respectively provided with a clamping groove and a clamping protrusion, and the two adjacent water receiving sub-grooves are mutually clamped through the clamping groove and the clamping protrusion.
