The snap-fit ​​portion 220 is located at the lower end of the main body 210 and abuts against the lower end of the limiting portion 110. The side of the main body 210 abuts against the inner side of the limiting portion 110. That is, the limiting portion 110 can also limit the mounting base 200, which can greatly improve the assembly efficiency of the mounting base 200. It should be noted that the receiving groove 221 is opened in the snap-fit ​​portion 220. The first sealing member 400 connects the bottom of the snap-fit ​​portion 220 and the inner wall of the kettle body 100 to seal the connection gap between the snap-fit ​​portion 220 and the kettle body 100.

[0034] In one embodiment, the heating component 300 is tightly attached to the upper end of the main body 210 by the second sealing member 500 to seal the connection gap between the heating component 300 and the main body 210, thereby improving the sealing effect.

[0035] In one embodiment, the main body 210 is further provided with a heat insulation member 600, which is connected to the bottom of the heating component 300. It should be noted that the main body 210 is provided with a downwardly recessed mounting groove (not shown in the figure) for installing the heat insulation member 600. The heat insulation member 600 can prevent the heat released by the heating component 300 from being transferred to the outside through the mounting base 200, thus avoiding burns.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
