Description

Electric kettle

Technical Field

The application relates to the technical field of liquid heating containers, in particular to an electric kettle.

Background

The common small household electrical appliances for boiling water in daily life of the hot water kettle are popular among consumers due to the advantages of convenience and quickness in water boiling.

Some of the insulating pot that are comparatively novel among the prior art set up in the pot lid and empty the anti-overflow device, promptly, when the insulating pot emptys, empty the anti-overflow device and can seal the exhaust hole on the pot lid to prevent that the water in the kettle body from overflowing the leakage through the exhaust hole.

Some pouring anti-overflow devices are sealed by gravity elements, for example, gravity sealing elements are adopted, when the kettle body is poured, the gravity sealing element positioned below the liquid level seals one of the exhaust holes under the action of gravity; the gravity sealing piece above the liquid level does not block the other exhaust hole under the action of gravity, so that the thermos can still normally release pressure and exhaust air when toppling over.

For example, patent publication No. CN205197772U and patent name "electric kettle", fig. 1 is a schematic diagram of the electric kettle in a pouring state, as shown in fig. 1: the anti-overflow device mainly adopts the technical scheme that a first exhaust pipe 201 and a second exhaust pipe 202 are arranged on a kettle cover, a gravity sealing element and a lead cavity for accommodating the gravity sealing element are respectively arranged in the two exhaust pipes, and at the moment, the gravity sealing element in the second exhaust pipe 202 moves towards the air outlet end of the second exhaust pipe 202 under the action of gravity and is blocked; the gravity sealing element in the first exhaust pipe 201 moves towards the air inlet end of the first exhaust pipe 201 under the action of gravity and is not blocked, so that the first exhaust pipe 201 can normally release pressure and exhaust air.

However, due to the lead cavity, when the electric kettle is in a toppling state, the air inlet end of the first exhaust pipe 201 must be located below the lead cavity, otherwise, gravity sealing can cause the first exhaust pipe 201 to be blocked, and the kettle body cannot exhaust air and release pressure. However, the rated water containing amount of the electric kettle is lowered, namely, the liquid level cannot be higher than the air inlet end of the first exhaust pipe 201 in the toppling state, otherwise, the high pressure in the kettle body can press the water to be sprayed out through the first exhaust pipe 201 which is not sealed and blocked by gravity, and the toppling and overflowing preventing function is disabled.

In conclusion, the electric kettle pouring and anti-overflow device in the prior art has the problem that the pouring and anti-overflow effect is not ideal.
