[0023] In a first aspect, the present invention provides a technical means for a kettle lid structure that will not spill even if it falls over, the kettle lid structure includes a lower cover plate 1 and an upper cover plate 2, a circular passage is provided on one side of the lower cover plate 1, the circular 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 wall of the inner ring 3 and the inner wall of the outer ring 4, respectively, at least one circular side plate 6 with a notch 7 is provided between the inner ring 3 and the outer ring 4, The center of the circular side plate 6 overlaps 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 a notch 7, at least one air intake 8 is formed in the lower cover plate 1, the air intake 8 is adjacent to the baffle 5 and is located outside the inner ring 3, an exhaust port 9 is formed in the outer ring 4, and the upper cover plate 2 covers the side of the lower cover plate 1 on which the annular passage is installed and is fitted with the lower cover plate 1 with a seal.

[0024] Specifically, referring to FIG. 1 and FIG. 2, steam generated when boiling water enters the annular passage composed of the inner ring 3, the outer ring 4, the baffle 5 and the circular side plate 6 from the inlet 8 formed in the lower cover plate 1, the circular side plate 6 divides the annular passage into several small passages, adjacent small passages communicate with each other through the notches 7 in the circular side plate 6, the notches 7 in the circular side plate 6 are formed in the baffle 5 (i.e., the circular side plate 6 has one end welded to the baffle 5 and the other end not connected to the baffle 5), in this way, the steam flows from one small passage to another at the notches 7 until it flows into the exhaust port 9, and the steam is guided from inside the kettle and effectively exhausted, thereby reducing the pressure inside the kettle, and since the exhaust port 9 is in the outer ring 4 (i.e., the side wall of the kettle lid), compared with the conventional steam port being formed above the kettle lid, the risk of the user being scalded by steam when pouring water is effectively avoided. In addition, when the electric kettle falls over, the hot water in the kettle is likely to enter the kettle lid, so there is a risk of the hot water spilling out of the kettle lid. However, in the kettle lid of the present invention, even if a small amount of hot water enters the kettle lid when the electric kettle falls over, the circular side plate 6 and the baffle 5 are designed so that when a small amount of hot water flows, the flow direction is changed by blocking the baffle 5, and finally, the hot water level does not rise above the highest point of the circular side plate 6 (see Figures 3 and 4), and the hot water cannot flow beyond the circular side plate 6, thereby achieving the effect of preventing spillage. In addition, in this design, the kettle lid does not need to be fixed and can be positioned in any direction 360 degrees. The exhaust port 9 of the kettle lid is formed at a relatively high point of the outer ring 4 and is at a different height from the intake port 8, so that even if a large amount of hot water enters the kettle lid, the amount of hot water spilling out of the exhaust port 9 can be minimized, and the user can be prevented from being burned. When the fallen electric kettle is returned to its upright position, the upper surface of the lower cover plate 1 is inclined from the outside to the inside (the outside is higher and the inside is lower), so that the condensed water and the hot water in the kettle lid are guided back to the air intake 8 and are prevented from spilling out of the exhaust vent 9.The number of circular side plates 6 can be adjusted according to actual conditions as long as the anti-spill needs are met. When multiple circular side plates 6 are installed, the centers of the multiple circular side plates 6 overlap with the center of the inner ring, and 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, and 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, the multiple circular side plates 6 form a direction change passage in the annular passage.

[0025] As a preferred embodiment, in some examples, the lower cover plate 1 is further provided with some mounting frames 10 fixedly connected to the outer wall of the outer ring 4. The mounting frames 10 are for mounting a sealing member, which fits into the opening to form a seal, and can prevent steam and hot water from leaking from the gap between the kettle lid and the opening when the electric kettle falls over.

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

[0027] As a preferred embodiment, in some examples, the number of the mounting frames 10 is four. This number of the mounting frames 10 can meet general installation needs, and of course, the number of the mounting frames 10 can be adjusted according to actual demand.

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

[0029] As a preferred embodiment, in some examples, the number of the inlets 8 is two, and the two inlets 8 are arranged symmetrically. Referring again to FIG. 2, increasing the number of the inlets 8 contributes to steam entering the annular passage, which has the effect of quickly reducing the pressure in the kettle, and the number of the inlets 8 can be adjusted according to the actual demand as long as it meets the pressure reduction needs. The two inlets 8 are arranged symmetrically, which looks good.

[0030] As a preferred embodiment, in some examples, the lower cover plate 1 is further provided with a partition plate 12 located in the middle of the exhaust port 9. Referring again to FIG. 1, the partition plate 12 divides the exhaust port 9 into two, achieving a dividing effect, and avoiding concentrated exhaust of steam.

[0031] In a second aspect, the present invention provides a technical means for an electric kettle, which includes a kettle body and the above-mentioned kettle lid, and the kettle lid is placed on the opening of the kettle body. Referring to Fig. 7, the kettle lid of the present invention is applied 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 in the kettle body, and the kettle lid can effectively exhaust the steam, release the pressure in the kettle body, and avoid or minimize the water spilling when the electric kettle falls over.
