[0021] In the description of the present invention, unless otherwise clearly and specifically limited, "a plurality" means at least two, for example, two, three, etc. Further, unless there are other clear regulations and limitations, the terms "attachment", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a removable connection, an integral connection, a mechanical connection, or an electrical connection. It may be a direct connection or an indirect connection through an intermediate medium, or an internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific situation.

[0022] In the present invention, unless there are other clear regulations and limitations, when the first feature is "above" or "below" the second feature, the first feature may be in direct contact with the second feature, or the first feature and the second feature may be indirectly in contact through an intermediate medium.

When the first feature is "below", "below", and "below" the second feature, the first feature may be directly below or obliquely below the second feature, or it only indicates that the horizontal height of the first feature is smaller than that of the second feature.

[0023] In a first aspect, the present invention provides a technical means for a kettle lid structure that does not spill even when it falls. The kettle lid structure includes a lower cover plate 1 and an upper cover plate 2. An annular passage is installed on one side surface of the lower cover plate 1. The annular passage includes an inner ring 3, an outer ring 4, and a baffle 5. Both ends of the baffle 5 are fixedly connected to the outer side wall of the inner ring 3 and the inner side wall of the outer ring 4 respectively. At least one circular side plate 6 with a notch 7 is installed between the inner ring 3 and the outer ring 4. The center of the circular side plate 6 coincides with the center of the inner ring 3. One end of the circular side plate 6 is fixedly connected to the baffle 5, and the other end does not contact the baffle 5 so as to form the notch 7. At least one air inlet 8 is formed on the lower cover plate 1. The air inlet 8 is close to the baffle 5 and is located outside the inner ring 3. An exhaust port 9 is formed on the outer ring 4. The upper cover plate 2 is covered on the side surface of the lower cover plate 1 where the annular passage is installed and is sealingly fitted with the lower cover plate 1.

[0024] Specifically, referring to FIGS. 1 and 2, the steam generated during boiling enters the annular passage formed by the inner ring 3, the outer ring 4, the baffle 5, and the circular side plate 6 from the air intake 8 formed in the lower cover plate 1. The circular side plate 6 divides the annular passage into several small passages, and adjacent small passages communicate with each other through the notch 7 of the circular side plate 6. The notch 7 of the circular side plate 6 is formed in the baffle 5 (that is, one end of the circular side plate 6 is welded to the baffle 5 and the other end is not connected to the baffle 5). In this way, until the steam flows into the exhaust port 9, it enters from one small passage to another small passage at the notch 7, and the steam is effectively discharged after being guided out of the kettle. As a result, the pressure inside the kettle decreases. Since the exhaust port 9 is located in the outer ring 4 (that is, the side wall of the kettle lid), compared with the conventional case where the steam port is formed above the kettle lid, the risk of scalding the user by steam when pouring water is effectively avoided. Also, when the electric kettle accidentally falls over, there is a risk that the hot water inside the kettle will easily enter the kettle lid and spill out from the kettle lid. However, for the kettle lid in the present invention, even if a small amount of hot water enters the kettle lid when the electric kettle falls over, due to the design of the circular side plate 6 and the baffle 5, when a small amount of hot water flows, its flow direction is changed by the blocking of the baffle 5, and finally, the liquid level of the hot water will not be higher than the highest point of the circular side plate 6 (see FIGS. 3 and 4), and the hot water cannot flow over the circular side plate 6, thereby achieving an anti-spill effect. Also, in this design, the kettle lid does not need to be fixed and can be arranged in any direction of 360 degrees. Since the exhaust port 9 of the kettle lid is formed at a relatively high position of the outer ring 4 and there is a height difference from the air intake 8, even if a large amount of hot water enters the kettle lid, the amount of hot water spilling from the exhaust port 9 can be minimized, and the user can be prevented from being scalded. When the fallen electric kettle is returned to the vertical position, since the upper surface of the lower cover plate 1 slopes from the outside to the inside (the outside is high and the inside is low), the condensed water and the hot water that entered the kettle lid are guided back to the air intake 8, and spilling from the exhaust port 9 is avoided.The number of the circular side plates 6 can be adjusted according to the actual situation as long as the anti-spillage needs are satisfied. When a plurality of circular side plates 6 are installed, the centers of the plurality of circular side plates 6 overlap with the center of the inner ring. Among two adjacent circular side plates 6, one circular side plate 6 has one end welded to the left side of the baffle 5, and the notch 7 of the circular side plate 6 is located on the right side of the baffle 5. The other circular side plate 6 has one end welded to the right side of the baffle 5, and the notch 7 of the circular side plate 6 is located on the left side of the baffle, that is, a direction-changing passage is formed in the annular passage by the plurality of circular side plates 6.

[0025] As a preferred embodiment, in some embodiments, several mounting frames 10 fixedly connected to the outer side wall of the outer ring 4 are further installed on the lower cover plate 1. The mounting frame 10 is for mounting a sealing member. The sealing member fits and seals with the opening, and when the electric kettle falls down, it can prevent steam and hot water from leaking from the gap between the kettle lid and the opening.

[0026] In the above embodiment, further, several mounting frames 10 are installed at equal intervals along the circumferential direction of the outer ring 4. With this design, when mounting the sealing member, the mounting is more stable and the sealing effect is better.

[0027] As a preferred embodiment, in some embodiments, the number of several mounting frames 10 is four. This number of mounting frames 10 can meet general mounting needs. Of course, the number of mounting frames 10 can be adjusted according to actual requirements.

[0028] As a preferred embodiment, in some embodiments, a handle 11 is installed on the upper surface of the upper cover plate 2. Referring to FIG. 5, by installing the handle 11, the user can easily lift the kettle lid.

[0029] As a preferred embodiment, in some examples, the number of air inlets 8 is two, and the two air inlets 8 are symmetrically installed. Referring to FIG. 2 again, increasing the number of air inlets 8 contributes to the steam entering the annular passage, thereby achieving the effect of rapidly reducing the pressure inside the kettle. The number of air inlets 8 can be adjusted according to actual needs as long as the decompression requirements are met. The two air inlets 8 are symmetrically installed, which looks good.

[0030] As a preferred embodiment, in some examples, a partition plate 12 is further installed on the lower cover plate 1 at a position intermediate the exhaust ports 9. Referring to FIG. 1 again, the partition plate 12 bisects the exhaust ports 9, achieving a flow splitting effect and avoiding the concentrated discharge of steam.

[0031] In a second aspect, the present invention provides a technical means for an electric kettle, the electric kettle including a kettle body and the kettle lid, and the kettle lid being covered over the opening of the kettle body. Referring to FIG. 7, the kettle lid of the present invention is applicable to various heatable electric kettles such as ceramic electric kettles, stainless steel electric kettles, and glass electric kettles. When the electric kettle boils water, a large amount of high-temperature steam is generated inside the kettle body. The kettle lid effectively discharges the steam, relieving the pressure inside the kettle body, and when the electric kettle falls over, it can avoid or minimize water spillage.

[0032] In the description of this specification, the description referring to terms such as "one example", "some examples", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in combination with the example or examples are included in at least one example or example of the present invention. In this specification, the schematic expressions of the above terms are not necessarily for the same example or example. The specific features, structures, materials, or characteristics described can be appropriately combined in any one or more examples or examples. Also, as long as there is no contradiction, those skilled in the art can combine different examples or examples and the features of different examples or examples described in this specification.

[0033] The above embodiments are merely for explaining the technical idea and features of the present invention, and are intended to enable those skilled in the art to understand and implement the content of the present invention, rather than limiting the protection scope of the present invention. Any equivalent changes or modifications made based on the essence of the content of the present invention should be included within the protection scope of the present invention.
