[0035] Please see Figures 1-4 This invention illustrates a preferred embodiment of a kettle, comprising:

[0036] A pot body 1 has an inner cavity 11 and an opening 12. The inner cavity 11 extends vertically along the pot body 1, and the opening 12 is located at the bottom of the pot body 1 and communicates with the inner cavity 11.

[0037] Heating plate 2 has a groove 211 on its top, which accommodates the lower part of the kettle body 1. The side wall of the groove 211 fits against the outer side wall of the kettle body 1. Heating plate 2 covers the opening 12 to close the opening 12. Heating plate 2 and inner cavity 11 form a water boiling chamber. Heating plate 2 is used to heat the water in the water boiling chamber.

[0038] The kettle of this utility model has a groove 211 set on the heating plate 2, which covers the lower part of the kettle body 1. At the same time, the side wall of the groove 211 fits the outer side wall of the kettle body 1, so that there is no gap between the heating plate 2 and the kettle body 1. This solves the problem of scale, dust and other dirt being trapped in the gap between the heating plate 2 and the kettle body 1, and can ensure the hygiene of drinking water.

[0039] See Figure 2 In one embodiment, the lower outer peripheral wall of the pot body 1 has a positioning groove 141, which extends to the bottom of the pot body 1 and is arranged around the vertical center line of the pot body 1.

[0040] The heating plate 2 includes a plate body 21 and a positioning ring 22. The positioning ring 22 is located around the plate body 21 and is formed by bending upwards relative to the periphery of the plate body 21. The positioning ring 22 is inserted into the positioning groove 141. In this way, through the cooperation of the positioning ring 22 and the positioning groove 141, the heating plate 2 can be quickly installed in the set position of the kettle body 1, which not only improves the installation efficiency but also enhances the connection stability between the heating plate 2 and the kettle body 1.

[0041] In one embodiment, the positioning ring 22 and the kettle body 1 are connected together by welding, so as to reliably fix the heating plate 2 and the kettle body 1 together, and at the same time, seal the connection between the heating plate 2 and the kettle body 1 to prevent water leakage.

[0042] Of course, in other embodiments, the positioning ring 22 and the kettle body 1 can also be connected together by casting. In this way, a seamless connection between the positioning ring 22 and the kettle body 1 can be achieved, that is, a seamless connection between the heating plate 2 and the kettle body 1 can be achieved, thereby improving the overall strength and sealing of the kettle.

[0043] Of course, in other embodiments, the positioning ring 22 and the kettle body 1 can also be connected together by forging, which can make the connection between the positioning ring 22 and the kettle body 1 tighter and improve the load-bearing capacity and service life of the kettle.

[0044] See Figure 2 In one embodiment, a receiving groove 3 is formed between the upper end of the positioning ring 22 and the kettle body 1. The receiving groove 3 is used to accommodate the welded protrusion (not shown in the figure) formed after the positioning ring 22 and the kettle body 1 are welded together. In this way, the positioning ring 22 and the kettle body 1 can be reliably connected together by the welded protrusion. At the same time, the welded protrusion can be hidden in the receiving groove 3, so that the welded protrusion will not protrude relative to the outer wall of the kettle body 1, avoiding scratching the hand. At the same time, the outer wall of the kettle is smoother and simpler, improving the aesthetic appearance of the kettle.
