Description

Technical Field

[0001] This utility model relates to the field of pressure cooker pressure relief valve technology, and in particular to a pressure cooker with automatic pressure relief and anti-clogging device. Background Technology

[0002] A pressure cooker, also known as a pressure pot or pressure casserole, is a type of kitchen cookware. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus accelerating the cooking process. Its advantages include time and energy savings. However, its disadvantages include the potential for explosion and injury if the pressure valve is faulty or blocked. Existing pressure cooker pressure relief valves generally suffer from complex structures and high costs, especially electromagnetic pressure relief valves. Because the internal environment of a pressure cooker is high-temperature and high-pressure, the performance of electronic components such as circuits and sensors becomes unstable after long-term use, leading to poor reliability of the pressure relief valve. This paper proposes a pressure cooker with an automatic pressure relief and anti-blocking device to solve these problems. Utility Model Content

[0003] To solve the technical problem of automatic pressure relief in pressure cookers, this utility model provides a pressure cooker with automatic pressure relief and anti-blocking devices.

[0004] This utility model is achieved using the following technical solution: a pressure cooker with an automatic pressure relief and anti-blocking device, comprising a pot body, a pot lid on the upper side of the pot body, a limiting platform fixedly connected to the lower side of the pot lid, a turntable rotatably connected inside the limiting platform, a third culvert and a first culvert respectively opened on the turntable, one end of the third culvert communicating with one end of the first culvert, a connecting pipe fixedly connected to one side of the turntable, one end of the connecting pipe communicating with one end of the first culvert, a housing fixedly connected to one side of the limiting platform, a turntable drive mechanism for rotating the turntable within the limiting platform provided inside the housing, and an exhaust mechanism provided on the upper side of the limiting platform.

[0005] As a further improvement to the above solution, the turntable drive mechanism includes a limiting ball that is slidably connected to the outside of the connecting pipe. A fixed frame is rotatably connected to the outside of the limiting ball. A limiting rod mechanism is provided on the lower side of the fixed frame, and a pressure balancing mechanism is provided on the upper side of the fixed frame.

[0006] As a further improvement to the above solution, the limiting rod mechanism includes a limiting rod that is slidably connected to the bottom side of the inside of the box, and the upper end of the limiting rod is fixedly connected to the lower side of the fixed frame.

[0007] As a further improvement to the above solution, the pressure balancing mechanism includes a sealing groove opened on the limiting platform, a spring fixedly connected to the inner side of the sealing groove, and a sealing piston slidably connected to the lower end of the spring.

[0008] As a further improvement to the above solution, the exhaust mechanism includes an exhaust platform fixedly connected to the upper side of the limiting platform, and a second culvert is provided on the exhaust platform.

[0009] As a further improvement to the above scheme, the outer side of the exhaust platform is provided with multiple exhaust holes, which are distributed in a circumferential array, and one end of the multiple exhaust holes is connected to the second culvert.

[0010] As a further improvement to the above solution, the side of the housing away from the turntable is connected to an anti-blocking cover.

[0011] As a further improvement to the above scheme, when the gas pressure inside the pot increases, the sealing piston moves upward, the spring is compressed and deformed, the limiting ball moves upward away from the initial position and rotates, the connecting pipe swings and pushes the turntable to rotate until the upper end of the third culvert is connected to the lower end of the second culvert.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves automatic pressure relief by increasing the gas pressure inside the pot, which causes the fixed frame to move up and down, indirectly enabling the connecting pipe to drive the turntable to rotate, connecting the No. 2 culvert to the No. 3 culvert, and discharging the high-pressure gas inside the pot to the outside of the pot through the exhaust port. It has the advantages of simple structure and high reliability.

[0014] 2. This utility model improves the safety of pressure cooker use by installing an anti-clogging cover on the side of the body and by having the connecting pipe slowly swing around the turntable as the pressure inside the pot increases. The air inlet of the connecting pipe is also small. With the protection provided by the anti-clogging cover, it is difficult for splashed food inside the pot to clog the port of the connecting pipe, thereby improving the safety of pressure cooker use.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figures 1-7 This embodiment of a pressure cooker with an automatic pressure relief and anti-clogging device includes a pot body 1, a pot lid 2 on the upper side of the pot body 1, a limiting platform 5 fixedly connected to the lower side of the pot lid 2, and a turntable 7 rotatably connected inside the limiting platform 5. (Please refer to...) Figure 6 As shown, the turntable 7 is a cylindrical platform structure. The turntable 7 is provided with a No. 3 culvert 17 and a No. 1 culvert 8. One end of the No. 3 culvert 17 is connected to one end of the No. 1 culvert 8. The No. 3 culvert 17 and the No. 1 culvert 8 are connected and intersected at the center of the turntable 7.

[0027] Please combine Figure 6 As shown, a connecting pipe 9 is fixedly connected to one side of the turntable 7, and one end of the connecting pipe 9 is connected to one end of the first culvert 8. A box 11 is fixedly connected to one side of the limiting platform 5. A turntable drive mechanism for rotating the turntable 7 within the limiting platform 5 is provided inside the box 11. An exhaust mechanism is provided on the upper side of the limiting platform 5.

[0028] Please combine Figure 5 As shown, the turntable drive mechanism includes a limiting ball 12 that is slidably connected to the outside of the connecting pipe 9. The limiting ball 12 has an open channel inside. A fixed frame 4 is rotatably connected to the outside of the limiting ball 12. A limiting rod mechanism is provided on the lower side of the fixed frame 4, and a pressure balancing mechanism is provided on the upper side of the fixed frame 4.

[0029] With the above technical solution, when the fixed frame 4 moves up and down, the connecting pipe 9 can drive the limiting ball 12 to rotate inside the fixed frame 4.

[0030] Please combine Figure 5 As shown, the limiting rod mechanism includes a limiting rod 10 that is slidably connected to the bottom side of the inside of the housing 11, and the upper end of the limiting rod 10 is fixedly connected to the lower side of the fixed frame 4.

[0031] Please combine Figure 6 As shown, the pressure balancing mechanism includes a sealing groove 14 opened on the limiting platform 5. The sealing groove 14 is a cylindrical groove. A spring 15 is fixedly connected to the inner side of the sealing groove 14. It should be noted that in this embodiment, when the spring 15 reaches its maximum deformation, that is, when the pot body 1 reaches the warning pressure relief threshold, the upper end of the third culvert 17 is connected to the lower end of the second culvert 16, and the pressure relief state begins in the pot body 1.

[0032] Please combine Figure 6 As shown, a sealing piston 13 is fixedly connected to the lower end of the spring 15 and slidably connected to the inner side of the sealing groove 14. A sealing ring is provided between the sealing piston 13 and the sealing groove 14;

[0033] Please combine Figure 4 As shown, the exhaust mechanism includes an exhaust platform 3 fixedly connected to the upper side of the limiting platform 5, and a second culvert 16 is provided on the exhaust platform 3.

[0034] Please combine Figure 7 As shown, multiple exhaust holes 18 are provided on the outer side of the exhaust platform 3. The multiple exhaust holes 18 are arranged in a circular array, and one end of the multiple exhaust holes 18 is connected to the second culvert 16.

[0035] Please combine Figure 4 The side of the box 11 away from the turntable 7 is connected to an anti-blocking cover 6, which can block splashed food and prevent blockage.

[0036] When the gas pressure inside the pot 1 increases, the sealing piston 13 moves upward, the spring 15 is compressed and deformed, the limiting ball 12 moves upward and rotates away from the initial position, the connecting pipe 9 swings and pushes the turntable 7 to rotate until the upper end of the third culvert 17 is connected to the lower end of the second culvert 16.

[0037] The implementation principle of a pressure cooker with automatic pressure relief and anti-blocking device in this embodiment is as follows: When the pressure inside the pot body 1 increases and exceeds the external atmospheric pressure, the sealing piston 13 moves upward along the sealing groove 14, compressing the spring 15 and causing it to deform. At the same time, the sealing piston 13 drives the fixed frame 4 to move upward, and the fixed frame 4 drives the limit rod 10 to slide upward. The upper limit ball 12 of the fixed frame 4 rotates, causing the connecting pipe 9 to swing around the turntable 7. The turntable 7 rotates inside the limit platform 5, causing the outer port of the third culvert 17 on the limit platform 5 to successfully connect with the lower port of the second culvert 16. After successful connection, the gas can flow along the connecting pipe 9, passing through the first culvert 8, the third culvert 17, and the second culvert 16 in sequence, and finally discharged from the exhaust port 18.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
