TECHNICAL FIELD

[0002] The existing cooking utensils such as electric pressure cookers, the electromagnetic valve thereof utilizes the principle that the magnetic force valve and the electromagnetic chuck can generate both suction force and repulsive force to realize stepless adjustment of the pressure limiting value of the electric pressure cooker. The implementation manner is that when the electromagnetic chuck is not powered, the pressure limiting pressure of the electric pressure cooker is determined by the suction force generated by the electromagnetic chuck and the magnetic force valve; when the electromagnetic chuck is powered with direct current which gradually increases, the electromagnetic chuck will generate the same magnetic pole as the adjacent surface of the magnetic force valve, and the repulsive force of the same magnetic pole will reduce the suction force between the magnetic force valve and the electromagnetic chuck until the repulsive force completely lifts the magnetic force valve.

[0023] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1-5 As shown, the intelligent electrically controlled pressure solenoid valve of the present invention includes a valve body 1, a valve stem 11, and a pressure cover 2. The valve body 1 has a channel hole 13, the valve stem 11 passes through the channel hole 13 and is fixedly connected to the valve body 1, and the valve stem 11 has a pressure relief hole 12. The pressure cover 2 is movably mounted on the upper end of the valve stem 11. The valve body 1 has an electromagnetic component 3, and the pressure cover 2 has a permanent magnet 23. The lower end of the valve body 1 has a pipe connector 4, one end of which is connected to the valve stem 11, and the pipe connector 4 is connected to the pressure relief hole 12. The pipe connector 4 has a pressure sensor 41. The pressure sensor 41 and the electromagnetic component 3 are respectively connected to the main control board of the electric pressure cooker 5 through leads. The electromagnetic component 3 generates magnetism when energized, which, in conjunction with the permanent magnet 23 on the pressure cap 2, drives it to move up and down at the upper end of the valve stem 11. When the electromagnetic component 3 and the permanent magnet 23 generate an attractive force, the pressure cap 2 cuts off the pressure relief hole 12, maintaining pressure in the pressure cooker; when the electromagnetic component 3 and the permanent magnet 23 generate a repulsive force, the pressure cap 2 moves upward along the upper end of the valve stem 11, thereby opening the pressure relief hole 12 and releasing pressure from the pressure cooker. The magnitude of the force generated by the pressure cap 2 is related to the current intensity passing through the electromagnetic component 3, while the pressure sensor 41 can detect the pressure inside the electric pressure cooker 5. Both the pressure sensor 41 and the electromagnetic component 3 are connected to the main control board, thereby enabling automated control and adjustable control of the working pressure of the electric pressure cooker 5.
[0025] The working principle of this invention is as follows: The pressure sensor 41 monitors the real-time pressure inside the pressure cooker. The working pressure of the pressure cooker is set according to the different ingredients. During operation, a rated voltage is applied to the electromagnetic component 3, and the magnetic core of the electromagnetic coil attracts the pressure cover 2. When the pressure inside the cooker exceeds the set pressure, the pressure sensor 41 outputs a frequency signal or voltage signal to the microcontroller on the central control board. Upon receiving the signal, the central control board changes the direction of the current in the solenoid valve, causing the electromagnetic component 3 and the pressure cover 2 to magnetically repel each other and levitate, thereby releasing pressure. This achieves intelligent control of pressure holding and releasing. The central control board of the electric pressure cooker 5 integrates a voltage instability alarm signal module, and the central control board has a built-in pressure calibration microcontroller to ensure the working accuracy of the pressure solenoid valve.
[0026] The pipe connector 4 is equipped with a sensing base 42, the upper end of which is open. The pressure sensor 41 is encapsulated and fixed inside the upper port of the sensing base 42. A branch air passage 43 is laterally opened inside the pipe connector 4, and a bypass hole 14 is opened on the side wall of the valve stem 11. One end of the pipe connector 4 is fixedly connected to the valve body 1, thereby allowing one end of the branch air passage 43 to communicate with the pressure relief hole 12 through the bypass hole 14. The lower end of the sensing base 42 is fixedly connected to the pipe connector 4, and the inner cavity of the sensing base 42 is connected to the branch air passage 43. The sensing base 42 is used to encapsulate the pressure sensor 41 in its upper port. The lower end of the pressure relief hole 12 on the valve stem 11 is connected to the inner cavity of the pressure cooker. The pressure inside the pressure cooker is transmitted to the sensing base 42 through the pressure relief hole 12, the bypass hole 14, and the branch air passage 43. The pressure sensor 41 monitors the pressure in real time.
[0027] The lower end of the sensing base 42 is fixedly connected to the pipe connector 4. A constant pressure hole 44 is provided on the sensing base 42. The upper end of the constant pressure hole 44 is connected to the upper port of the sensing base 42, and the lower end of the constant pressure hole 44 is connected to the branch air passage 43. A sealing cap 45 is provided on the other end of the pipe connector 4. The branch air passage 43 is arranged horizontally, and the pressure sensor 41 is installed in the upper port of the sensing base 42. The condensate generated by the water vapor entering the branch air passage 43 can flow back into the pressure cooker to avoid the water vapor affecting the working accuracy of the pressure sensor 41.
[0028] The valve body 1 has a channel hole 13 formed inside, through which the electromagnetic component 3 passes. The valve rod 11 passes through the channel hole 13. The valve body 1 encapsulates the valve rod 11 and the electromagnetic component 3 through a molding process, and the valve body 1 forms an insulating barrier between the valve rod 11 and the electromagnetic component 3. The pipe connector 4 is integrally formed with the valve body 1. A bypass hole 14 is provided on the side wall of the valve rod 11. One end of the pipe connector 4 is connected to the bypass hole 14 on the valve rod 11 to connect to the pressure relief hole 12. The valve rod 11 passes through the channel hole 13, and the valve rod 11 and the channel hole 13 are spaced apart from the electromagnetic component 3. Water vapor flowing through the channel hole 13 and the valve rod 11 will not enter the electromagnetic component 3, thereby effectively improving the insulation performance and stability of the electromagnetic component 3.
[0029] The electromagnetic component 3 includes a keel 31 and an iron core 32. A coil 33 is wound around the outer periphery of the keel 31. A first through hole 34 is formed at the center of the keel 31. The iron core 32 passes through the first through hole 34 and is fixedly connected to it. A second through hole 35 is formed at the center of the iron core 32. An inner cylinder 36 passes through the second through hole 35. The inner cylinder 36 is fitted to the inner wall of the second through hole 35 of the iron core 32. The lower end of the inner cylinder 36 is connected to the lower end of the keel 31 through an extension structure, thereby covering the lower end of the iron core 32. A channel hole 13 is formed at the center of the inner cylinder 36. A valve rod 11 passes through the channel hole 13. The valve body 1 is integrally fixedly connected to the valve rod 11, the keel 31 and the iron core 32 through a molding process. The inner cylinder 36 and the keel 31 are integrally covered on the iron core 32. Furthermore, the valve body 1 is integrally formed and encapsulates the keel 31 and the iron core 32, which can effectively improve the insulation performance and stability of the pressure solenoid valve.
[0030] The valve body 1 is equipped with a shielding cover 15, which has an end face partition and a circumferential partition, forming an upward-opening shielding cavity. The keel 31, iron core 32, inner cylinder 36, and coil 33 are all located within the shielding cavity of the shielding cover 15. The upper end of the iron core 32 is equipped with a magnetic chuck 37, which is located inside the upper port of the shielding cover 15 and attached to the upper end face of the keel 31. The shielding cover 15 is used to isolate the magnetism of the lower end of the iron core 32. When the coil 33 is energized, the iron core 32 becomes magnetic, which in turn causes the magnetic chuck 37 at the upper end of the iron core 32 to generate corresponding magnetic poles and magnetic force, which, together with the permanent magnet 23, causes the pressure cover 2 to generate corresponding blocking pressure.
[0031] The upper end of the valve stem 11 is provided with an air nozzle 16, and the pressure cover 2 is provided with an exhaust hole 21. The upper end of the air nozzle 16 is inserted into and passes through the exhaust hole 21 from the lower port. The upper port of the exhaust hole 21 is provided with a pressure relief plate 22. The pressure cover 2 is provided with a permanent magnet 23, and the bottom surface of the pressure relief plate 22 is provided with a plug 24. The plug 24 is movably abutted against the upper port of the air nozzle 16. The plug 24 may have a conical structure, while the upper port of the air nozzle 16 has a flared shape. The air nozzle 16 passes through the exhaust hole 21, allowing the pressure cover 2 to move up and down along the air nozzle 16. Under the action of gravity, the plug 24 on the pressure relief plate 22 contacts the air nozzle 16 to cut off the pressure relief hole 12. When the pressure inside the electric pressure cooker 5 exceeds the force generated by the electromagnetic component 3, the pressure cover 2 is lifted by the air pressure, and the pressure inside the electric pressure cooker 5 is released to the outside through the pressure relief hole 12, the air nozzle 16 and the exhaust hole 21 on the air valve rod 11.
[0032] When the electromagnetic component 3 is not energized, the pressure cap 2 seals the upper end of the pressure relief hole 12 of the gas valve rod 11 under the action of gravity. When a positive current is passed through the electromagnetic component 3, the electromagnetic component 3 generates an attractive force on the permanent magnet 23. At this time, the pressure exerted by the pressure cap 2 on the upper end of the pressure relief hole 12 becomes stronger, while the lower end of the gas valve rod 11 is connected to the inner cavity of the electric pressure cooker 5. When the pressure inside the electric pressure cooker 5 is sufficient to push the pressure cap 2, the pressure and gas inside the electric pressure cooker 5 are released to the outside through the pressure relief hole 12. Then, when the pressure inside the electric pressure cooker 5 decreases, the pressure cap 2 seals the pressure relief hole 12 again to repeat the above process.
[0033] When a reverse current is applied to the electromagnetic component 3, it drives the pressure cover 2 to rise, thereby releasing the pressure inside the electric pressure cooker 5. Crucially, the magnitude of the electromagnetic force generated by the electromagnetic component 3 can be adjusted, thus enabling stepless adjustment of the working pressure of the electric pressure cooker 5.
[0034] A limiting baffle 25 is provided on the inner wall of the exhaust port 21, and a guide opening 26 is provided on the limiting baffle 25. The air nozzle 16 is movably inserted into the guide opening 26, and an anti-detachment flange 17 is provided at the upper end of the air nozzle 16 above the limiting baffle 25. The pressure cover 2 also includes an exhaust hood 27, the lower end of which is paired with the upper end of the valve body 1 to form a detachable connection, and a sealing gasket 28 is provided between the lower end of the exhaust hood 27 and the valve body 1. An exhaust port 29 is provided at the upper end of the exhaust hood 27. The limiting baffle 25 can be made of elastic material so that the anti-detachment flange 17 can pass through the guide opening 26 during installation. The limiting baffle 25 is used to restrict the pressure cover 2 to prevent it from falling off the air nozzle 16 under pressure impact. Furthermore, the anti-detachment flange 17 can adopt a threaded structure, and the guide port 26 is machined with internal threads. The pressure cover 2 can be screwed into and assembled on the air nozzle 16. The anti-detachment flange 17 and the limiting baffle 25 can only be separated by a screw engagement to prevent the pressure cover 2 from falling off the air nozzle 16 under impact.
[0035] The intelligent electrically controlled pressure solenoid valve is applied to the electric pressure cooker 5. The electric pressure cooker 5 is equipped with a display module, which can display the set pressure value, real-time pressure value, and temperature value of the electric pressure cooker 5 in real time. The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the claims of this patent application are included within the scope of this patent application.
