Technical issues

[0004] The existing tipping-overflow-proof electric kettle has an extremely complex structure and high cost. The production and installation are complicated and tedious, and there is a very high defect rate in production. Moreover, the conditions for triggering the anti-overflow valve are too complicated. Under special circumstances, the triggering conditions of the anti-overflow valve cannot be met at the same time, and it is impossible to prevent excessive water from overflowing when the kettle is tipped over.

[0005] Therefore, the existing technology still needs to be improved and developed. Technical Solutions

[0006] The purpose of the utility model is to address the defects and shortcomings of the existing technology and provide a rotatable anti-overflow structure with a reasonable structure, a scheduling channel on the pot mouth that can be self-closed, and simple operation.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] The utility model discloses a rotatable anti-overflow structure, comprising a kettle body, wherein a lid seat is provided on the mouth of the kettle body; a wheel assembly and a plurality of air outlets are provided on the lid seat, the wheel assembly being rotatably connected to the lid seat via a rotating shaft, and the plurality of air outlets are arranged in sequence around the rotating shaft; the wheel assembly has a notch, and the center of gravity of the notch and the wheel assembly are respectively located on both sides of the rotating shaft. The lid seat closes the mouth of the kettle body, and the notch and the air outlet constitute an exhaust passage of the kettle body. When boiling water normally, hot steam in the kettle body can be discharged from any air outlet through the notch. When the kettle body is tilted in any direction, especially when pouring water, the wheel assembly is acted upon by gravity to cause its center of gravity to tend to a lower position. At this time, one of the air outlets paired with the notch is in a relatively high position, and the wheel assembly closes the other air outlets, thereby preventing water from overflowing from the exhaust passage.

[0009] According to the above solution, the lid base is provided with a top cover, which is provided with exhaust holes. The wheel assembly covers a plurality of exhaust holes, and any of the exhaust holes can be paired with the notches to communicate with the exhaust holes. The top cover and the lid base have a cavity, and the exhaust holes, the notches, the cavity, and the exhaust holes constitute an exhaust passage. The top cover is used to enclose the wheel assembly, and the wheel assembly is rotatably mounted on the lid base so that the notches on the wheel assembly can be paired with any of the exhaust holes, thereby communicating with the exhaust passage, and steam in the pot body can be discharged through the exhaust passage.

[0010] According to the above solution, the wheel assembly includes a flange cover and a pendulum. The flange cover is rotatably mounted on the center of the pot lid seat via a rotating shaft. The notch is formed on the edge of the flange cover. One end of the pendulum is fixedly connected to the rotating shaft, and the other end of the pendulum forms the center of gravity of the wheel assembly. The flange cover covers the plurality of air outlets and is paired with any of the air outlets via the notch. When the pot body is tilted, the flange cover and the pendulum rotate around the rotating shaft. Under the action of gravity, the pendulum tends to a lower position, and the notch moves to a higher position to pair with the corresponding air outlet. Even if water in the pot body partially submerges the pot lid seat due to the tilt, the water cannot overflow through the higher air outlet.

[0011] According to the above solution, a retaining ring is provided on the upper end surface of the pot lid seat, and a shaft seat is provided at the center of the retaining ring. The flange cover is connected to the shaft seat via a rotating shaft and is rotatably disposed within the retaining ring, and the flange cover is spaced apart from the pot lid seat. A first silicone ring is provided between the flange cover and the pot lid seat, and the first silicone ring is fixedly connected to the flange cover and has a shaped opening that avoids the notch. The retaining ring is used to establish a mounting position on the pot lid seat, allowing the flange cover to be rotatably disposed on the pot lid seat. Furthermore, the flange cover is mounted on the shaft seat via a rotating shaft, and the flange cover is spaced apart from the pot lid seat. The first silicone ring surrounds the gap between the flange cover and the pot lid seat, so that when one of the air outlets is paired with the notch, the other air outlets are covered by the first silicone ring and the flange cover. It is understood that water in the pot body can enter the gap between the flange cover and the pot lid seat, but cannot enter the exhaust passage through the notch.

[0012] According to the above solution, a bottom cover is provided on the lower end surface of the lid seat, the bottom cover being spaced apart from the lid seat and having an air inlet hole.

[0024] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0025] As shown in Figures 1-5, the rotatable overflow prevention structure of the present invention includes a kettle body 1, with a lid seat 2 disposed on the mouth of the kettle body 1; the lid seat 2 is provided with a wheel assembly and a plurality of air outlets 21. The wheel assembly is rotatably connected to the lid seat 2 via a rotating shaft 22, and the plurality of air outlets 21 are sequentially spaced around the rotating shaft 22; the wheel assembly has a notch 31, with the center of gravity of the notch 31 and the wheel assembly located on either side of the rotating shaft 22. The lid seat 2 seals the mouth of the kettle body 1, and the notch 31 and the air outlets 21 form an exhaust passage for the kettle body 1. During normal boiling, hot steam in the kettle body 1 can be discharged from any of the air outlets 21 through the notch 31. When the kettle body 1 is tilted in any direction, especially when pouring water, the wheel assembly is acted upon by gravity so that its center of gravity tends to be low. At this time, one of the air vents 21 paired with the notch 31 is in a relatively high position, and the wheel assembly closes the other air vents 21, thereby preventing water from overflowing from the exhaust channel.

[0026] The lid base 2 is provided with a top cover 23, which is provided with exhaust holes 24. The wheel assembly covers a plurality of exhaust holes 21, and any of the exhaust holes 21 can be paired with the notches 31 to communicate with the exhaust holes 24. The top cover 23 and the lid base 2 define a cavity, and the exhaust holes 21, the notches 31, the cavity, and the exhaust holes 24 constitute an exhaust passage. The top cover 23 is used to enclose the wheel assembly. The wheel assembly is rotatably mounted on the lid base 2 so that the notches 31 thereon can be paired with any of the exhaust holes 21, thereby communicating with the exhaust passage, and steam within the kettle body 1 can be discharged through the exhaust passage.

[0027] The wheel assembly includes a flange cover 3 and a pendulum 32. The flange cover 3 is rotatably mounted on the center of the lid base 2 via a rotating shaft 22. A notch 31 is formed on the edge of the flange cover 3. One end of the pendulum 32 is fixedly connected to the rotating shaft 22, and the other end of the pendulum 32 forms the center of gravity of the wheel assembly, so that the center of gravity and the notch 31 are respectively located on either side of the rotating shaft 22. The flange cover 3 covers the plurality of air outlets 21 and is paired with any of the air outlets 21 through the notch 31. When the kettle body 1 is tilted, the flange cover 3 and the pendulum 32 rotate about the rotating shaft 22. Under the action of gravity, the pendulum 32 tends to a lower position, while the notch 31 moves to a higher position to pair with the corresponding air outlet 21. Even if water in the kettle body 1 partially submerges the lid base 2 due to the tilt, the water cannot overflow through the air outlet 21 at the higher position.

[0028] The lid base 2 has a retaining ring 25 disposed on its upper end surface. A shaft seat 26 is located at its center. The flange cover 3 is connected to the shaft seat 26 via a rotating shaft 22, thereby being rotatably disposed within the retaining ring 25. The flange cover 3 is spaced apart from the lid base 2. A first silicone ring 33 is disposed between the flange cover 3 and the lid base 2. The first silicone ring 33 is fixedly connected to the flange cover 3 and has a shaped opening 34 that allows for the opening 31 to be avoided. The retaining ring 25 is used to establish a mounting position on the lid base 2, allowing the flange cover 3 to be rotatably disposed on the lid base 2. Furthermore, the flange cover 3 is mounted on the shaft seat 26 via the rotating shaft 22, with a spaced-apart arrangement between the flange cover 3 and the lid base 2. The first silicone ring 33 surrounds the gap between the flange cover 3 and the lid base 2, ensuring that when one of the air outlets 21 is paired with the opening 31, the other air outlets 21 are covered by the first silicone ring 33 and the flange cover 3. It is understandable that the water in the kettle body 1 can enter the gap between the flange cover 3 and the kettle cover seat 2, but cannot enter the exhaust channel through the notch 31.

[0029] A bottom cover 27 is provided on the lower end surface of the lid seat 2. The bottom cover 27 is spaced apart from the lid seat 2 and is provided with an air inlet 28.

The trigger 44 can drive the water baffle 41 to reciprocate through the connecting rod structure 43, thereby closing or opening the water outlet 4. The second silicone ring 42 can improve the sealing performance of the water baffle 41 when closing the water outlet 4. The trigger 44, connecting rod structure 43, and hinge base 45 are existing conventional structures, so they will not be described again.

[0031] A third silicone ring 11 is provided between the lid seat 2 and the pot mouth of the pot body 1, and the third silicone ring 11 is fixedly connected to the lid seat 2. The lid seat 2 is installed on the pot body 1 to close the pot mouth, and the third silicone ring 11 is used to ensure the sealing of the connection between the lid seat 2 and the pot body 1.

[0032] The kettle body 1 is provided with a spout 12 on one side, a handle 13 on the other side, and a heating base 14 on the bottom of the kettle body 1. The spout 12 is paired with the water outlet 4 on the lid base 2, and the spout 12 and the handle 13 are arranged on opposite sides of the kettle body 1.
