Description

Technical Field

[0001] The utility model relates to the technical field of electric kettles, and particularly relates to a structure of an electric kettle lid. Background Art

[0002] The structure of the related anti-leakage kettle lid for pouring an electric kettle is provided with a weight at the air outlet of the kettle lid. When the kettle is poured, the weight moves to seal the air outlet, so as to prevent the water in the kettle from flowing out of the kettle through the air outlet channel.

[0003] However, when the kettle is poured just after the water boils, due to the residual heat of the heating plate at the bottom of the kettle, the water in the kettle will continue to boil and generate a large amount of water vapor. At this time, the air outlet is closed by the weight, and the air pressure in the kettle rises, causing the safety valve to open and release water, so that a large amount of high-temperature boiling water flows out of the kettle, posing a greater risk of scalding the user. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structure of an electric kettle lid. A second through hole is provided on the partition plate. When pouring, the boiling water slowly flows to the water storage chamber through the second through hole, preventing the internal air pressure from being too high and flushing open the water outlet valve when the boiling water is poured, resulting in the rapid overflow of the boiling water and causing scalding and other situations.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A structure of an electric kettle lid includes a bracket and a partition plate, and a water storage chamber is formed between the bracket and the partition plate;

[0007] The partition plate includes a central part and an edge part, and the position of the central part is lower than that of the edge part;

[0008] A first through hole is provided in the central part, and a weight is provided below the first through hole;

[0009] A plurality of uniformly distributed second through holes are provided in the edge part;

[0010] The aperture of the second through hole is smaller than that of the first through hole.

[0011] In some embodiments, the aperture of the second through hole is between 0.8 mm and 1.5 mm.

[0012] In some embodiments, the ratio of the hole pitch between the second through holes to the aperture is between 1.5 and 2.5.

[0013] In some embodiments, the ratio of the width dimension of the edge part to the radius of the partition plate is between 0.15 and 0.4.

[0014] In some embodiments, the partition plate is in a conical shape or a frustum shape.

[0015] In some embodiments, a cavity capable of accommodating the weight is provided below the first through hole.

[0016] Advantages of the present utility model: The partition plate is provided with a second through hole. When pouring, boiling water slowly flows from the second through hole to the water storage chamber, preventing the internal air pressure from being too high when the boiling water boils and pours, which may push open the water outlet valve, resulting in the rapid overflow of boiling water and causing scalding and other situations.

Specific Embodiments

[0024] The present utility model will be further described in detail below with reference to the drawings.

[0025] Refer to Figures 1 to 6 , a kettle lid structure of an electric kettle, comprising a kettle lid 100, the kettle lid 100 is arranged at the top or above the inner liner 200, and the kettle lid 100 includes a bracket 1 and a partition plate 2;

[0026] Refer to Figure 3 , the bracket 1 is provided with a water outlet nozzle 11 and a valve port 13, the water outlet nozzle 11 is communicated with the valve port 13, the valve port 13 is communicated with the inner liner 200, and the valve port 13 is provided with a water outlet valve 5; the bracket 1 is further provided with a steam port 12, and a steam pipe can be connected to the steam port 12, and steam can be discharged through the steam port 12;

[0027] The space formed by the bracket 1 and the partition plate 2 is the water storage chamber 10;

[0028] Refer to Figure 5 and Figure 6, the partition 2 includes a central portion 2a and an edge portion 2b, and the position of the central portion 2a is lower than that of the edge portion 2b;

[0029] The central portion 2a is provided with a first through hole 21, and a weight 4 is provided below the first through hole 21;

[0030] The edge portion 2b is provided with a plurality of uniformly distributed second through holes 23;

[0031] The aperture of the second through hole 23 is smaller than that of the first through hole 21.

[0032] Reference Figure 4 , when the water in the electric kettle boils and is poured, the weight 4 blocks the first through hole 21. At this time, the water and steam can only flow into the water storage chamber 10 through the second through holes 23. Since the flow resistance of the gas is less than that of the water, the steam can smoothly escape from the second through holes 23 in the upper position A area, while the boiling water can only slowly flow out through the second through holes 23 in the lower position B area. When the water storage chamber 10 is full, the water will flow out of the kettle. In this way, the overflow of the boiling water can be slowed down, and the safety of using the kettle can be improved; when the boiling water boils, the internal air pressure is relatively high and the water outlet valve 5 is pushed open, resulting in the rapid overflow of the boiling water and causing burns and other situations.

[0033] Among them, the position of the second through hole 23 is higher than that of the first through hole 21. When pouring, the boiling water first pushes the weight 4 to block the first through hole 21 to prevent the boiling water from flowing out quickly through the first through hole 21. Then, the boiling water can only slowly flow out through the second through hole 23.

[0034] The aperture of the second through hole 23 is between 0.8 mm and 1.5 mm. The smaller aperture can increase the flow resistance of the water. When the electric kettle is poured, it can promote the slow flow of the boiling water to the water storage chamber 10.

[0035] The ratio of the hole pitch between the second through holes 23 to the aperture is between 1.5 and 2.5. The hole pitch is the center distance between two adjacent second through holes 23.

[0036] Reference Figure 6 , the ratio of the width dimension W of the edge portion 2b to the radius R of the partition 2 is between 0.15 and 0.4. For example, when the radius R of the partition 2 is about 60 mm, the width dimension W of the edge portion 2b can be about 10 mm, 15 mm or 20 mm, etc. In this way, the second through holes 23 are arranged in a proper-sized area to ensure the steam circulation and realize the slow outflow of the boiling water.

[0037] The partition 2 is in a conical or frustum shape, and the second through holes 23 can be arranged on the conical surface of the conical or frustum shape.

[0038] Reference Figure 3, a cavity 22 capable of accommodating a plumb bob 4 is provided below the first through hole 21. The plumb bob 4 can move along the axial direction of the cavity 22. When the kettle is tilted, water pushes the plumb bob 4 to block the first through hole 21 to prevent water from flowing out quickly. When the kettle is not tilted, the plumb bob 4 moves away from the first through hole 21 under its own weight, thereby opening the first through hole 21. Among them, the plumb bob 4 can be in the shape of a frustum of a cone or a cylinder.

[0039] Reference Figure 2 , the kettle lid 100 further includes a lower cover body 3. The lower cover body 3 is provided below the partition plate 2. The material of the lower cover body 3 is stainless steel, and a hollow structure is provided on the bottom wall of the lower cover body 3.

[0040] The above discloses only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
