Specifically, the kettle body 1 and the base 14 are electrically connected via a coupler 15, and the base 14 has a power cord.

[0045] like Figure 2As shown, the kettle body 1 includes a glass kettle body 111 and a protective cover 112, wherein the protective cover 112 is wrapped around the outer wall of the glass kettle body 111 and is integrally formed with the handle 11. The bottom of the protective cover 112 is connected to the base 14. A visual window 16 is provided on the side wall of the protective cover 112, through which a user can observe the situation inside the glass kettle body 111. The glass kettle body 111 is located in the position of the visual window 16 and is marked with a water level scale.

[0046] like Figure 2 , Figure 3 As shown, the glass kettle body 111 is open on the top and is provided with a spout 113 on the side opposite to the handle 11. The edge of the spout 113 is provided with a circular convex edge 114. The circular convex edge 114 makes the water flow of the spout 113 more concentrated when the water is discharged, and is not easy to be scattered and dripped, while improving the impact resistance effect. When the glass kettle body 111 is bumped, the circular convex edge 114 can better disperse the impact force along the circular edge, so that the spout 113 is not easy to be chipped due to impact.

[0047] Further, such as Figure 2 , Fig. 9 As shown, the glass kettle body 111 is movably covered with a kettle cover 19 , and the kettle cover 19 is movably connected to the handle 11 through a movable module 3 .

[0048] The movable module 3 includes a movable block 31 integrally formed with the pot cover 19 and a positioning block 32 fixedly installed in the handle 11 by screws.
