[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Please also read Figures 1 to 3 The utility model discloses an electric pressure cooker with multi-stage pressure full boiling cooking. The electric pressure cooker with multi-stage pressure full boiling cooking in this embodiment includes a pot body 1, an exhaust valve shell 2, an elastic valve core component 3 and a pressure regulating component 4. The exhaust valve shell 2 is arranged on the pot body 1 and is provided with an exhaust hole 211 connected to the inside of the pot body 1. The elastic valve core component 3 is arranged in the exhaust valve shell 2 and closes the exhaust hole 211. The elastic valve core component 3 is used to open the exhaust hole 211 when the steam pressure in the pot body 1 is greater than its elastic force. The pressure regulating component 4 is used to adjust the elastic force of the elastic valve core component 3. With such a design, when the user needs to cook different ingredients, the elastic force of the elastic valve core component 3 can be adjusted through the pressure regulating component 4 to adjust the exhaust pressure, and then adjust the full boiling cooking pressure of the electric pressure cooker, so that the electric pressure cooker can meet the user's cooking needs for different ingredients.

[0026] In some embodiments, the pressure regulating assembly 4 includes an electromagnet 41, a slider 43 and a lifting rod 44. The slider 43 is connected to the electromagnet 41. The movement directions of the lifting rod 44 and the slider 43 are perpendicular to each other. Under the drive of the electromagnet 41, the slider 43 is separated from the lifting rod 44 so that the lifting rod 44 does not exert a force on the elastic valve core assembly 3 (such as Figure 2 As shown), or, the slider 43 pushes the lifting rod 44 to move until the lifting rod 44 squeezes the elastic valve core component 3, so that the lifting rod 44 applies a force on the elastic valve core component 3 (as shown Figure 3As shown). With such a design, when low-pressure full boiling cooking is required, the electromagnet 41 drives the slider 43 to separate the slider 43 from the lifting rod 44, the external force on the lifting rod 44 disappears, and the lifting rod 44 does not exert a force on the elastic valve core component 3. At this time, the exhaust pressure of the elastic valve core component 3 at the exhaust hole 211 is only its own elastic force, that is, the pressure initially set by the elastic valve core component 3. When the pressure in the pot exceeds the pressure on the elastic valve core component 3, the steam in the pot pushes up the elastic valve core component 3, and the elastic valve core component 3 is separated from the exhaust hole 211 on the exhaust valve housing 2 for exhaust, thereby realizing low-pressure boiling cooking; when high-pressure full boiling cooking is required, the electromagnet 41 drives the slider 43 so that the slider 43 pushes the lifting rod 44 until the lifting rod 44 squeezes the elastic valve core component 3, and the lifting rod 44 exerts a force on the elastic valve core component 3, thereby increasing the exhaust pressure of the elastic valve core component 3 at the exhaust hole 211. At this time, a larger pressure is required in the pot to exceed the pressure of the elastic valve core component 3, thereby realizing high-pressure full boiling cooking. Among them, by controlling the distance that the electromagnet 41 drives the slider 43, different elastic deformation amounts of various elastic valve core components 3 can be achieved, thereby achieving various different pressure cooking.

[0027] Furthermore, the pot body 1 is provided with a first guide block 11, and the first guide block 11 is provided with a first guide groove 12 and a second guide groove (not shown) which are perpendicular to each other. The slider 43 is provided with a second guide block 431, and the second guide block 431 is slidably arranged on the first guide groove 12. The lifting rod 44 is provided with a third guide block 441, and the third guide block 441 is slidably arranged on the second guide groove. With such a design, the slider 43 and the lifting rod 44 can both move in directions perpendicular to each other, so as to better convert the horizontal movement of the slider 43 into the lifting movement of the lifting rod 44.

[0028] Furthermore, in order to facilitate the conversion of the horizontal movement of the slider 43 into the lifting movement of the lifting rod 44, the slider 43 is provided with a first inclined surface 432 facing the lifting rod 44, and the lifting rod 44 is provided with a second inclined surface 442 adapted to the first inclined surface 432. With such a design, the slider 43 moves horizontally under the push of the electromagnet 41, the first inclined surface contacts the second inclined surface 442, and the lifting rod 44 can move up and down under the push of the first inclined surface 432.

[0029] In some embodiments, in order for the electromagnet 41 to push the slider 43, a pushing member 42 is provided on the electromagnet 41, and the slider 43 is connected to the pushing member 42. The electromagnet 41 pushes the slider 43 to move through the pushing member 42, that is, the electromagnet 41 drives the pushing member 42 to move, and the pushing member 42 drives the slider 43 to move.

[0030] Specifically, the pushing member 42 includes a pushing rod 421 and a pushing block 422. One end of the pushing rod 421 is fixed to the electromagnet 41, and the pushing block 422 is arranged at the other end of the pushing rod 421. A positioning groove 433 is provided on the slider 43, and the pushing block 422 is located in the positioning groove 433 so that the slider 43 is connected to the pushing block 422.

[0031] In some embodiments, the elastic valve core assembly 3 includes a valve core 31, a spring 32 and a pressure plate 33. The valve core 31 is used to close or open the exhaust hole 211. The pressure plate 33 is arranged on the exhaust valve housing 2 on the side opposite to the exhaust hole 211. The spring 32 abuts between the valve core 31 and the pressure plate 33. The pressure regulating assembly 4 adjusts the elastic force of the elastic valve core assembly 3 through the pressure plate 33. Specifically, when low-pressure full boiling cooking is required, the pushing member 42 on the electromagnet 41 drives the slider 43 away from the lifting rod 44, the pressing block is not squeezed by the lifting rod 44, the spring 32 is at the original compression amount, and the valve core 31 is acted upon by the initial pressure of the spring 32. When the pressure in the pot exceeds this pressure, the steam in the pot lifts up the pressure-sealed valve core 31, and the valve core 31 is separated from the exhaust hole 211 for exhaust, thereby realizing low-pressure boiling cooking; when high-pressure boiling cooking is required, the pushing member 42 on the electromagnet 41 drives the slider 43 to move toward the lifting rod 44 and pushes the lifting rod 44. The lifting rod 44 moves downward under the action of its own second inclined surface 442 and the first inclined surface 432 of the slider 43, and at the same time pushes the pressing block downward, at which time the compression amount of the spring 32 is increased, and the valve core 31 increases the downward pressure under the action of the spring 32. At this time, a larger pressure is required in the pot to exceed the pressure of the valve core 31, and the valve core 31 is pushed upward to realize the separation of the valve core 31 from the exhaust hole 211 for exhaust, thereby realizing high-pressure boiling cooking.

[0032] Furthermore, the valve core 31 extends in the direction toward the pressure plate 33 to form a first guide column 311, and the pressure plate 33 extends in the direction toward the valve core 31 to form a second guide column 331. A third guide groove 332 is provided in the second guide column 331, and the first guide column 311 extends into the third guide groove 332. A part of the spring 32 is sleeved outside the first guide column 311 and another part is sleeved outside the second guide column 331. With such a design, on the one hand, through the cooperation of the first guide column 311 on the valve core 31 and the second guide column 331 on the pressure plate 33, the valve core 31 and the pressure plate 33 can move along a preset direction; on the other hand, the first guide column 311 and the second guide column 331 can also guide the spring 32 so that the spring 32 can be compressed and reset along the preset direction.

[0033] Furthermore, the valve core 31 is provided with a top cone 312 facing the exhaust hole 211, and the top cone 312 is used to close or open the exhaust hole 211. The design of providing the top cone 312 on the valve core 31 can improve the sealing performance at the exhaust hole 211.

[0034] In some embodiments, the exhaust valve housing 2 includes a valve seat 21 and a valve cover 22. The valve seat 21 is arranged on the pot body 1. The valve cover 22 covers the valve seat 21. The valve seat 21 is provided with an exhaust hole 211. The elastic valve core assembly 3 is arranged between the valve seat 21 and the valve cover 22.

[0035] The utility model provides an electric pressure cooker with multi-stage pressure full boiling cooking, which includes a pot body 1, an exhaust valve housing 2, an elastic valve core assembly 3 and a pressure regulating assembly 4. The exhaust valve housing 2 is arranged on the pot body 1 and is provided with an exhaust hole 211 connected to the inside of the pot body 1. The elastic valve core assembly 3 is arranged in the exhaust valve housing 2 and closes the exhaust hole 211. The elastic valve core assembly 3 is used to open the exhaust hole 211 when the steam pressure in the pot body 1 is greater than its elastic force. The pressure regulating assembly 4 is used to adjust the elastic force of the elastic valve core assembly 3. With such a design, when the user needs to cook different ingredients, the elastic force of the elastic valve core assembly 3 can be adjusted through the pressure regulating assembly 4 to adjust the exhaust pressure, thereby adjusting the full boiling cooking pressure of the electric pressure cooker, so that the electric pressure cooker can meet the user's cooking needs for different ingredients.
