[0035] Referring to Figure 2 and Figure 3, the outer side wall of the end of the elastic tube 2 away from the weight block 3 is connected with a first clamping ring 21 and a second clamping ring 22, the end of the elastic tube 2 away from the weight block 3 passes through the air outlet hole 11, the first clamping ring 21 and the second clamping ring 22 are clamped at the two ends of the air outlet hole 11 respectively, and are tightly abutted against the top wall of the first cover body 1, specifically, the outer diameters of the first clamping ring 21 and the second clamping ring 22 are both larger than the hole diameter of the air outlet hole 11, and the first clamping ring 21 and the second clamping ring 22 are tightly abutted against the top and bottom of the top wall of the first cover body 1 respectively. Further, the outer diameter of the elastic tube 2 is matched with the hole diameter of the air outlet hole 11. The close size matching of the elastic tube 2 and the air outlet hole 11, and the tight abutment of the first clamping ring 21 and the second clamping ring 22 against the top wall of the first cover body 1 form a good seal and ensure that the elastic tube 2 is firmly installed at the air outlet hole 11 of the top wall of the first cover body 1.

[0036] Referring to Figure 2 and Figure 3 , the first clamping ring 21 and the second clamping ring 22 are integrally formed with the elastic tube 2. The materials of the first clamping ring 21, the second clamping ring 22 and the elastic tube 2 are all food-grade silicone materials. The first clamping ring 21 and the second clamping ring 22 are integrally formed with the elastic tube 2, and the integrated design makes the connection part more stable, without connection gaps or weak points, reducing the risk of displacement or seal failure of the elastic tube 2 due to loose connection.

[0037] Referring to Figure 2 and Figure 3 , the first clamping ring 21 is provided with a guide surface 211 on the side away from the weight block 3. When installing the elastic tube 2, the guide surface 211 can play a guiding role, making the elastic tube 2 more easily pass through the air outlet hole 11, reducing the installation difficulty and improving the installation efficiency, while also reducing the damage to the edges of the elastic tube 2 and the air outlet hole 11 during installation, protecting the structural integrity of the elastic tube 2 and the first cover body 1, and being beneficial to prolonging the service life.

[0038] Referring to Figure 2 and Figure 3 , the top of the weight block 3 is integrally formed with a connecting tube 32, the connecting tube 32 communicates with the through hole 31, the outer diameter of the connecting tube 32 is larger than the inner diameter of the elastic tube 2, and the outer diameter of the connecting tube 32 can be accurately controlled according to actual needs and the specification parameters of the elastic tube 2. The connection between the elastic tube 2 and the weight block 3 is realized by sleeving one end of the elastic tube 2 on the outer wall of the connecting tube 32, and the sleeved part is tightly fitted by the elastic force of the elastic tube 2, forming a stable and well-sealed connection structure.

[0039] Referring to Figures 1-3, the outer side wall of the first cover body 1 is provided with a sealing element 13 for sealing the spout of the electric kettle. The sealing element 13 is a plurality of silica gel rings arranged around the outer side wall of the first cover body 1. When the kettle cover is closed on the spout of the electric kettle, the silica gel ring can tightly fit the edge of the spout to form a reliable sealing barrier. Whether in the normal process of placing the electric kettle to boil water, or when it is shaken or tilted, it can effectively prevent the hot water or steam in the kettle from leaking out from the gap between the spout and the kettle cover, not only ensuring the safety of use, but also avoiding the possible harm to the surrounding people due to the leakage of hot water.

[0040] Referring to Figure 2 and Figure 3 , the pouring anti-spill kettle cover further comprises a second cover body 4 arranged on the top of the first cover body 1, the second cover body 4 is connected with the first cover body 1 by ultrasonic wave, the second cover body 4 is provided with an exhaust hole 41, the top of the first cover body 1 is provided with a protrusion 12, the bottom of the second cover body 4, the protrusion 12 and the top of the first cover body 1 form a cavity 5, and the cavity 5 is in communication with the exhaust hole 41 and the air outlet hole 11 respectively. When the electric kettle is normally boiling, the steam in the kettle enters the cavity 5 through the air outlet hole 11 of the first cover body 1, the cavity 5 disperses and buffers the steam pressure, and then the steam is discharged through the exhaust hole 41 of the second cover body 4. The cavity 5 not only allows the steam to be discharged smoothly and orderly, avoids poor exhaust and noise problems, but also blocks dust and impurities from entering the kettle to keep the water clean.

[0041] The implementation principle of embodiment 1 is as follows:

[0042] In the normal use state of the electric kettle, the elastic tube 2 of the first cover body 1 is in a relaxed state due to the natural drooping of the counterweight 3, and the steam can smoothly pass through the through hole 31 of the counterweight 3, the elastic tube 2 and the air outlet hole 11 into the cavity 5 formed by the second cover body 4 and the protrusion 12 of the first cover body 1, and finally be discharged through the exhaust hole 41 of the second cover body 4, effectively maintaining the balance of the pressure in the kettle and ensuring the smooth progress of the boiling process.

[0043] When the electric kettle is accidentally poured, the counterweight 3 deviates towards the inner side wall of the electric kettle and pulls the elastic tube 2, causing the elastic tube 2 to gradually stretch and bend and deform. As the degree of bending increases, the lumen of the elastic tube 2 becomes narrower and narrower until it is closed, successfully blocking the path of the boiling water flowing to the air outlet hole 11, thereby effectively preventing the boiling water from overflowing from the kettle cover, greatly improving the safety of the electric kettle during use and avoiding the risk of burns to the user caused by the overflow of boiling water.
