When the electric kettle is lifted by the handle 120, the handle 120 is inclined upward, and the water outlet nozzle 110 is inclined downward to pour water.

[0029] As shown in the figure, Figure 1 The kettle body 100 is arranged in an arc-shaped barrel shape, the water outlet nozzle 110 is arranged as a swan neck nozzle, a kettle cavity 01 for storing water is formed in the kettle body 100, the top of the kettle body 100 is a kettle opening, and a kettle cover is installed at the kettle opening;

[0030] The bottom of the pot cavity 01 is the chassis 130 , and a base 140 is provided below the chassis 130 . A cavity for assembling heating components and the like is formed between the chassis 130 and the base 140 .

[0031] A steam pipe 200 is provided in the pot cavity 01. The steam pipe 200 includes a coil section 210 and an extension section 220. The coil section 210 is located at a high position in the pot cavity 01 and is coiled along the inner wall of the pot cavity 01. The upper end of the extension section 220 is connected to the coil section 210. The lower end of the extension section 220 extends downward from the bottom of the pot cavity 01, that is, extends downward through the bottom plate 130. The steam pipe 200 is generally made of a metal pipe and is formed by bending the metal pipe. Figure 1 The middle kettle body 100 is in an arc-shaped barrel shape, and the inner wall of the kettle cavity 01 is arc-shaped. Therefore, the coil section 210 is arc-shaped and coiled on the inner wall surface of the kettle cavity 01; the beginning of the coil section 210 is provided with an upper steam inlet 201, and the lower end of the extension section 220 is provided with a lower steam outlet 202.

[0032] like Figure 3 As shown, when viewed from above, the bottom of the pot cavity 01 has a center point O, the upper steam inlet 201 forms a projection point A on the bottom of the pot cavity 01, and the lower steam outlet 202 forms a projection point B on the bottom of the pot cavity 01. In the winding direction of the coil section 210, the angle ∠AOB is α, and α ≥ 180°;

[0033] Here, the coil section 210 is wound in a direction starting from the steam inlet 201, and the direction in which the coil section 210 extends is the winding direction, that is, Figure 3 The counterclockwise direction is the winding direction.

[0034] Continue as Figure 3 As shown, the projection of the connecting line between the water outlet 110 and the handle 120 at the bottom of the kettle cavity 01 is the connecting axis L, and the projection point B of the lower steam outlet 202 is not on the connecting axis L.

[0035] In one embodiment, the upper steam inlet 201 is positioned higher than the highest water level in the kettle cavity 01 , ensuring that the upper steam inlet 201 is also located above the liquid level when boiling water.

[0036] In one embodiment, the coil section 210 is coiled around the inner wall of the kettle cavity 01 for at least one circle, or the coil section 210 is provided with multiple circles. After providing multiple circles, when the kettle cavity 01 is under rated water volume, after the electric kettle is tilted or tipped over, at least one section of the coil section 210 is kept above the liquid surface, and the hot water cannot overcome gravity and flow back to the section above the liquid surface, so that a large amount of boiling hot water will not gush out of the steam pipe instantly, which is safer to use.

[0037] In one embodiment, the coiled tube section 210 is wound around the inner wall of the pot cavity 01 for less than one circle. Figure 3 As shown,Figure 3 The coiled length of the coil section 210 is less than one turn, which can effectively save material and meet the angle of ∠AOB being α, α≥180°;

[0038] As shown in the drawings, in the case that the coiled length of the coil section 210 is less than one turn, when the electric kettle is tilted, due to the water outlet nozzle 110 and the handle 120 arranged on the kettle body 100, the electric kettle will always keep the handle 120 side downward or the water outlet nozzle 110 side downward, or keep balance according to the lever principle. Figures 6-11 As shown in the drawings, in the case that the coiled length of the coil section 210 is less than one turn, when the electric kettle is tilted, due to the water outlet nozzle 110 and the handle 120 arranged on the kettle body 100, the electric kettle will always keep the handle 120 side downward or the water outlet nozzle 110 side downward, or keep balance according to the lever principle.

[0039] As shown in the drawings, after the electric kettle is tilted, the water outlet nozzle 110 is directed to the left upper side, and the handle 120 is directed to the right lower side and contacts the ground, at this time, partial coil sections in the coil section 210 are above the liquid surface, and the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface, so that the boiling hot water cannot flow out from the steam pipe 200.

[0041] As shown in the drawings, after the electric kettle is tilted, the water outlet nozzle 110 is directed to the left lower side and contacts the ground, and the handle 120 is directed to the right upper side, at this time, partial coil sections in the coil section 210 are above the liquid surface, and the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface, so that the boiling hot water cannot flow out from the steam pipe 200. Figure 8 As shown in the drawings, after the electric kettle is tilted, the water outlet nozzle 110 is directed to the left lower side and contacts the ground, and the handle 120 is directed to the right upper side, at this time, partial coil sections in the coil section 210 are above the liquid surface, and the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface, so that the boiling hot water cannot flow out from the steam pipe 200.
