The electric pressure cooker with at least two stages of pressure full boiling cooking in this embodiment comprises a pot body 1, an exhaust valve 2, a driving member 3, a push rod 4 and an elastic member 5. The exhaust valve 2 is slidably arranged on the pot body 1 up and down, the driving member 3 is arranged on the pot body 1, the push rod 4 is arranged on the driving member 3, and the elastic member 5 is arranged on the push rod 4; when the driving member 3 drives the push rod 4 to move in a direction away from the exhaust valve 2, the elastic member 5 is separated from the exhaust valve 2, and the electric pressure cooker is in a first state; when the driving member 3 drives the push rod 4 to move in a direction close to the exhaust valve 2, the elastic member 5 abuts against the exhaust valve 2, and the electric pressure cooker is in a second state. With such a design, when low-pressure full-boiling cooking is required, the electric pressure cooker is adjusted to the first state, the exhaust pressure of the exhaust valve 2 is the weight of the exhaust valve 2 itself, and when the pressure in the electric pressure cooker exceeds the weight of the exhaust valve 2, the steam in the electric pressure cooker pushes up the exhaust valve 2 to exhaust, thereby achieving low-pressure full-boiling cooking; when high-pressure full-boiling cooking is required, the electric pressure cooker is adjusted to the second state, the exhaust pressure of the exhaust valve 2 is the sum of the weight of the exhaust valve 2 and the elastic force of the elastic part 5, and when the pressure in the electric pressure cooker exceeds the sum of the weight of the exhaust valve 2 and the elastic force of the elastic part 5, the steam in the electric pressure cooker pushes up the exhaust valve 2 to exhaust, thereby achieving high-pressure full-boiling cooking.
[0028] The pot body 1 comprises a pot body for holding food and a pot cover for covering the pot body, and the exhaust valve 2, the driving member 3, the push rod 4 and the elastic member 5 are all arranged on the pot cover.
[0029] In some embodiments, the push rod 4 is provided with a through hole, the elastic member 5 includes a guide column 51 and a spring 52, the guide column 51 is movably arranged in the through hole, the first end and the second end of the guide column 51 are both located outside the through hole, the spring 52 is sleeved on the second end of the guide column 51, and when the electric pressure cooker is in the second state, the second end of the guide column 51 abuts against the exhaust valve 2. With such a design, when the pressure in the electric pressure cooker exceeds the sum of the weight of the exhaust valve 2 and the elastic force of the elastic member 5, the steam in the electric pressure cooker pushes up the exhaust valve 2 to exhaust, and the guide column 51 moves relative to the push rod 4 under the action of the exhaust valve 2 and squeezes the spring 52, so that the exhaust valve 2 can be depressurized; when the electric pressure cooker is depressurized or the guide column 51 is separated from the exhaust valve 2, the guide column 51 moves and resets under the action of the elastic force of the spring 52.
[0030] Furthermore, in order to prevent the guide post 51 from escaping from the through hole and the spring 52 from escaping from the guide post 51, the first end of the guide post 51 is provided with a first limiting portion 511 having an outer diameter greater than the through hole to prevent the guide post 51 from escaping from the through hole, and the second end of the guide post 51 is provided with a second limiting portion 512 having an outer diameter greater than the inner diameter of the spring 52 to prevent the spring 52 from escaping from the guide post 51, and the spring 52 abuts against the second limiting portion 512, and the second limiting portion 512 is used to abut against the exhaust valve 2.
[0031] In actual use, the spring 52 with different elasticity can be replaced according to actual use needs to meet different high-pressure cooking requirements.
[0032] In some embodiments, a contact piece 6 is provided on the outer wall of the exhaust valve 2. When the electric pressure cooker is in a first state, the driving member 3 drives the push rod 4 to move in a direction away from the exhaust valve 2 so that the elastic member 5 is separated from the contact piece 6. When the electric pressure cooker is in a second state, the driving member 3 drives the push rod 4 to move in a direction close to the exhaust valve 2 so that the elastic member 5 abuts against the contact piece 6, that is, the pressure is transmitted to the exhaust valve 2 through the contact piece 6.
[0033] Furthermore, in order to achieve the fixation of the contact member 6 on the exhaust valve 2 and the abutment with the elastic member 5, the contact member 6 includes a vertical portion 61 and a horizontal portion 62. The vertical portion 61 is fixed on the outer wall of the exhaust valve 2, one end of the horizontal portion 62 is connected to the bottom end of the vertical portion 61, and the other end of the horizontal portion 62 is extended outward. When the electric pressure cooker is in the second state, the driving member 3 drives the push rod 4 to move in the direction close to the exhaust valve 2 until the elastic member 5 abuts against the horizontal portion 62.
[0034] Preferably, there are two contact members 6, which are respectively located on both sides of the exhaust valve 2, the push rod 4 is a U-shaped structure, and there are two elastic members 5, which are respectively arranged at both ends of the push rod 4, and the two elastic members 5 are respectively used to abut against the two contact members 6. With such a design, the force applied to the exhaust valve 2 is better balanced.

From the above, the push rod 4 is a U-shaped structure, and accordingly, there are two limit grooves 71, and the two ends of the push rod 4 are respectively inserted into the two limit grooves 71.
[0036] See also Figure 3 In some embodiments, the exhaust valve 2 includes an exhaust pipe 23 disposed on the pot body 1 and a valve cap 24 slidably disposed on the exhaust pipe 23. The valve cap 24 is provided with a valve cone 21 protruding toward the exhaust pipe 23. In a natural state, the valve cone 21 extends into the pipe opening of the exhaust pipe 23 to seal the pipe opening of the exhaust pipe 23. The design of providing the valve cone 21 on the valve cap 24 can improve the sealing between the valve cap 24 and the exhaust pipe 23.
[0037] Furthermore, an exhaust cavity 22 is provided at the bottom of the valve cap 24, the valve cone 21 is located in the exhaust cavity 22, and the exhaust pipe 23 extends into the exhaust cavity 22. When the exhaust valve 2 is exhausted under the action of steam, the steam exhausted from the exhaust pipe 23 is discharged through the gap formed between the exhaust pipe 23 and the exhaust cavity 22.

[0039] The utility model provides an electric pressure cooker with at least two-stage pressure full boiling cooking. The electric pressure cooker includes a pot body 1, an exhaust valve 2, a driving member 3, a push rod 4 and an elastic member 5. The exhaust valve 2 is slidably arranged on the pot body 1, the driving member 3 is arranged on the pot body 1, the push rod 4 is arranged on the driving member 3, and the elastic member 5 is arranged on the push rod 4; when the driving member 3 drives the push rod 4 to move in a direction away from the exhaust valve 2, the elastic member 5 is separated from the exhaust valve 2, and the electric pressure cooker is in a first state; when the driving member 3 drives the push rod 4 to move in a direction close to the exhaust valve 2, the elastic member 5 abuts against the exhaust valve 2, and the electric pressure cooker is in a second state. With such a design, when low-pressure full-boiling cooking is required, the electric pressure cooker is adjusted to the first state, the exhaust pressure of the exhaust valve 2 is the weight of the exhaust valve 2 itself, and when the pressure in the electric pressure cooker exceeds the weight of the exhaust valve 2, the steam in the electric pressure cooker pushes up the exhaust valve 2 to exhaust, thereby achieving low-pressure full-boiling cooking; when high-pressure full-boiling cooking is required, the electric pressure cooker is adjusted to the second state, the exhaust pressure of the exhaust valve 2 is the sum of the weight of the exhaust valve 2 and the elastic force of the elastic part 5, and when the pressure in the electric pressure cooker exceeds the sum of the weight of the exhaust valve 2 and the elastic force of the elastic part 5, the steam in the electric pressure cooker pushes up the exhaust valve 2 to exhaust, thereby achieving high-pressure full-boiling cooking.
