[0030] 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.
[0031] Please also read Figures 1 to 4The utility model embodiment discloses an electric pressure cooker with multi-stage pressure full boiling cooking. The electric pressure cooker with multi-stage pressure full boiling cooking of this embodiment includes a pot body 1, an exhaust pipe 2, an exhaust valve 3, a counterweight 4 and a driving structure. The exhaust pipe 2 and the driving structure are fixedly arranged on the pot body 1, the exhaust valve 3 is movably arranged on the pot body 1, the counterweight 4 is movably arranged on the exhaust valve 3, and the driving structure is used to drive the counterweight 4 so that the counterweight 4 moves to be carried on the exhaust valve 3, or moves to be separated from the exhaust valve 3, or moves to drive the exhaust valve 3 to move. The electric pressure cooker can be transformed between the first state, the second state and the third state. When the exhaust valve 3 closes the outlet of the exhaust pipe 2 and the counterweight 4 is carried on the exhaust valve 3, the electric pressure cooker is in the first state. At this time, the exhaust valve 3 bears the weight of the counterweight 4 and increases in weight to H2. When the pressure in the electric pressure cooker exceeds the weight H2 of the exhaust valve 3, the steam in the pot pushes up the exhaust valve to achieve high-pressure full-boiling cooking. When the exhaust valve 3 closes the outlet of the exhaust pipe 2, the driving structure drives the counterweight 4 to move until the counterweight 4 is separated from the exhaust valve 3. When the electric pressure cooker is separated from the exhaust valve 3, the electric pressure cooker is in the second state. At this time, the weight of the exhaust valve 3 is reduced to the weight H1 of the exhaust valve 3 itself. When the pressure in the electric pressure cooker exceeds the weight H1 of the exhaust valve 3, the steam in the pot pushes up the exhaust valve 3 to exhaust the gas, thereby realizing low-pressure full boiling cooking; when the driving structure drives the counterweight block 4 to move, so that the counterweight block 4 drives the exhaust valve 3 to move to open the pipe mouth of the exhaust pipe 2, the electric pressure cooker is in the third state. At this time, the exhaust valve 3 opens the pipe mouth of the exhaust pipe 2, and the inside of the pot is connected with the outside world, thereby realizing pressure-free full boiling cooking.
[0032] With this design, users can adjust the electric pressure cooker to the first state to achieve high-pressure full-boiling cooking, or to the second state to achieve low-pressure full-boiling cooking, or to the third state to achieve pressureless full-boiling cooking, that is, to achieve multi-stage pressure full-boiling cooking, thereby meeting users' cooking needs for different ingredients.
[0033] In some embodiments, in order for the driving structure to smoothly drive the counterweight 4, the driving structure includes a driving member 51 for providing power and a transmission assembly for transmission, wherein the driving member 51 is disposed on the pot body 1, and the transmission assembly is connected to the driving member 51, and the driving member 51 is used to drive the transmission assembly. When the transmission assembly is in a natural state, the transmission assembly is separated from the counterweight 4, so that the counterweight 4 is carried on the exhaust valve 3; the transmission assembly drives the counterweight 4 to move under the drive of the driving member 51, so that the counterweight 4 moves to separate from the exhaust valve 3, or moves to drive the exhaust valve 3 to move, thereby realizing the transition of the electric pressure cooker between the first state, the second state and the third state.
[0034] Further, the driving member 51 is a motor, and the transmission assembly includes a transmission gear mechanism 521 and a lifting member 522. The transmission gear mechanism 521 is connected to the motor, and the lifting member 522 is movably arranged on the pot body 1. The lifting member 522 is provided with meshing teeth, and the lifting member 522 is meshed and connected with the transmission gear mechanism 521 through the meshing teeth. The motor is used to drive the transmission gear mechanism 521, and the transmission gear mechanism 521 drives the lifting member 522 to rise and fall, and the lifting member 522 pushes the counterweight 4 to move by rising and falling. It can be understood that in other embodiments, a transmission rod or the like can also be used as a design method of the transmission assembly, which is not limited here.
[0035] Furthermore, the transmission gear mechanism 521 includes a driving gear 5211 and a driven gear 5212, the driving gear 5211 is connected to the motor, the driven gear 5212 is rotatably arranged on the pot body 1, and the driving gear 5211, the driven gear 5212 and the lifting member 522 are meshed and connected in sequence. The design of two gear transmissions can improve the stability of the transmission. It is understandable that in other embodiments, the transmission gear mechanism 521 can also be designed as one, three or more than three, which is not limited here.
[0036] Preferably, the lifting member 522 is a cylindrical lifting member 522 and is movably sleeved on the exhaust valve 3, and the driven gear 5212 is a ring gear and is sleeved on the lifting member 522. With such a design, driven by the driving gear 5211, the driven gear 5212 rotates, and the lifting member 522 is lifted and lowered relative to the exhaust valve 3 under the action of the driven gear 5212 to drive the counterweight 4 to lift and lower.
[0037] The lifting member 522 extends upward to form a first lug 5221, and the first lug 5221 is used to push the counterweight 4. In order for the lifting member 522 to better push the counterweight 4, there are two first lugs 5221, which are respectively arranged on both sides of the lifting member 522.
[0038] In some embodiments, in order for the counterweight 4 to be able to realize three states of being carried on the exhaust valve 3, being separated from the exhaust valve 3, and driving the exhaust valve 3 to move to be separated from the exhaust pipe 2, an annular mounting groove 31 is provided on the exhaust valve 3, and the counterweight 4 is movably sleeved on the annular mounting groove 31. With such a design, when the electric pressure cooker is in the first state, the bottom of the counterweight 4 contacts the exhaust valve 3 to be carried on the exhaust valve 3, when the electric pressure cooker is in the second state, the counterweight 4 is separated from the exhaust valve 3, and when the electric pressure cooker is in the third state, the top of the counterweight 4 lifts up the exhaust valve 3 to drive the exhaust valve 3 to move.
[0039] Further, in order to facilitate the installation of the counterweight 4 on the exhaust valve 3, the exhaust valve 3 includes a lower valve body 32 and an upper valve body 33. The lower valve body 32 is used to close or open the pipe opening of the exhaust pipe 2. The lower valve body 32 extends upward to form a column 321. The upper valve body 33 is fixed to the top of the column 321 by fasteners, so that an annular mounting groove 31 is formed between the lower valve body 32 and the upper valve body 33. During installation, the counterweight 4 can be sleeved on the main body first, and then the upper valve body 33 can be fixed to the top of the main body by fasteners, so that the counterweight 4 can be movably sleeved in the annular mounting groove 31 of the exhaust valve 3. With such a design, when the electric pressure cooker is in the first state, the bottom of the counterweight 4 is supported on the lower valve body 32. When the electric pressure cooker is in the third state, the top of the counterweight 4 lifts up the upper valve body 33 to drive the exhaust valve 3 to move.
[0040] Furthermore, the outer periphery of the upper valve body 33 extends in the direction toward the lower valve body 32 to form a circumferential wall 331 , a clearance opening 332 is opened on the circumferential wall 331 , and the counterweight block 4 extends from the clearance opening 332 to the outside of the circumferential wall 331 to form a second lug 41 , and the driving structure drives the second lug 41 .
[0041] From the above, two first lugs 5221 are formed on the lifting member 522 , and the two first lugs 5221 drive the counterweight 4 . Accordingly, there are also two second lugs 41 , and the two second lugs 41 are respectively arranged on both sides of the counterweight 4 .
[0042] In some embodiments, the exhaust valve 3 is provided with a valve cone 322 protruding toward the exhaust pipe 2, and the valve cone 322 extends into the pipe opening of the exhaust pipe 2. When the exhaust valve 3 is exhausted under the action of steam, the valve cone 322 is separated from the pipe opening of the exhaust pipe 2. The design of providing the valve cone 322 on the exhaust valve 3 can improve the sealing between the exhaust valve 3 and the exhaust pipe 2.
[0043] The utility model provides an electric pressure cooker with multi-stage pressure full boiling cooking, which includes a pot body 1, an exhaust pipe 2, an exhaust valve 3, a counterweight 4 and a driving structure. The exhaust pipe 2 and the driving structure are fixedly arranged on the pot body 1, the exhaust valve 3 is movably arranged on the pot body 1, the counterweight 4 is movably arranged on the exhaust valve 3, and the driving structure is used to drive the counterweight 4 so that the counterweight 4 moves to be carried on the exhaust valve 3, or moves to be separated from the exhaust valve 3, or moves to drive the exhaust valve 3 to move. The electric pressure cooker can be transformed between the first state, the second state and the third state. When the exhaust valve 3 closes the outlet of the exhaust pipe 2 and the counterweight 4 is carried on the exhaust valve 3, the electric pressure cooker is in the first state. At this time, the exhaust valve 3 bears the weight of the counterweight 4 and increases in weight to H2. When the pressure in the electric pressure cooker exceeds the weight H2 of the exhaust valve 3, the steam in the pot pushes up the exhaust valve to achieve high-pressure full-boiling cooking. When the exhaust valve 3 closes the outlet of the exhaust pipe 2, the driving structure drives the counterweight 4 to move until the counterweight 4 is separated from the exhaust valve 3. When the electric pressure cooker is separated from the exhaust valve 3, the electric pressure cooker is in the second state. At this time, the weight of the exhaust valve 3 is reduced to the weight H1 of the exhaust valve 3 itself. When the pressure in the electric pressure cooker exceeds the weight H1 of the exhaust valve 3, the steam in the pot pushes up the exhaust valve 3 to exhaust the gas, thus realizing low-pressure full boiling cooking. When the driving structure drives the counterweight block 4 to move, so that the counterweight block 4 drives the exhaust valve 3 to move to open the outlet of the exhaust pipe 2, the electric pressure cooker is in the third state. At this time, the exhaust valve 3 opens the outlet of the exhaust pipe 2, and the inside of the pot is connected with the outside world, thus realizing pressure-free full boiling cooking. With such a design, the user can adjust the electric pressure cooker to the first state to realize high-pressure full boiling cooking, or to the second state to realize low-pressure full boiling cooking, or to the third state to realize pressure-free full boiling cooking, that is, to realize multi-stage pressure full boiling cooking, thereby meeting the user's cooking needs for different ingredients.
