[0026] Alternatively, the base 00 can be cancelled, and the base and the kettle body are designed as an integrated structure, and a heating member can be arranged at the bottom of the kettle body 100 to heat the water storage cavity 102.

[0027] Further, the kettle cover 200 is provided with a steam channel 400 inside, the steam channel 400 has a steam inlet 410 and a steam outlet 420, the steam inlet 410 is connected to the steam inlet hole 201 of the kettle cover 200, and the steam outlet 420 is connected to the exhaust channel 301 of the handle 300; the steam channel 400 comprises annularly distributed first channels 401, and the first channels 401 are distributed close to the edge of the kettle cover 200; when the electric kettle is tilted, at least a section of the first channels 401 is above the liquid level;

[0028] As shown in Figure 2 and Figure 3 The cross section of the kettle cover 200 is generally annular, the steam channel 400 is arranged inside the kettle cover 200, the steam channel 400 can be a single-ring channel or a plurality of concentrically distributed ring channels, and the ring channels are sequentially connected;

[0029] If the steam channel 400 is single-ring arranged, the first channels 401 constitute the steam channel 400;

[0030] If the steam passage 400 is arranged in multiple turns, the outermost turn of the passage is the first passage 401.

[0031] In this embodiment, the steam passage 400 is arranged in one turn, as shown in Figure 2 and Figure 3 The first passage 401 is equivalent to the steam passage 400, and the steam enters the steam passage 400 from the steam inlet 201 of the lid 200 and the steam inlet 410, flows along the steam passage 400 for one turn, and then flows out of the steam outlet 420 and to the exhaust passage 301.

[0032] In the case of the rated capacity, i.e., in the case of the maximum capacity of the water storage cavity, when the electric kettle is tilted, the water level in the water storage cavity 102 only submerges half or more than half of the lid 200, as shown in Figure 5 The water level submerges more than half of the lid 200, and then a small section of the steam passage 400 is above the liquid level, and water cannot flow upward against gravity, so water cannot flow out through the steam passage 400, thereby achieving the functions of preventing overflow and dripping.

[0033] In one embodiment, as shown in Figure 4 and Figure 6 A leakage prevention chamber 500 is arranged in the lid 200; the leakage prevention chamber 500 is connected between the steam outlet 420 of the steam passage 400 and the exhaust passage 301 of the handle 300; a sealing member 510 and an elastic member 520 are arranged in the leakage prevention chamber 500; the steam passage 400, the leakage prevention chamber 500, and the exhaust passage 301 are connected when the electric kettle is in a vertical state; the sealing member 510 separates the steam passage 400, the leakage prevention chamber 500, and the exhaust passage 301 when the electric kettle is in a tilted state or an inverted state.
