In this embodiment, without loss of generality, the top of the lid is provided with a recessed mounting area (not shown) in which the pressure adjustment mechanism is located. The first magnetic attraction piece 2 is preferably fixedly arranged in the exhaust valve 10, so that the exhaust valve 10 can provide anti-abrasion protection for the first magnetic attraction piece 2 compared with the case that the first magnetic attraction piece 2 is exposed out of the exhaust valve 10. Obviously, in other embodiments, the first magnetic element 2 can also be fixed on the lower surface of the exhaust valve 10.
In this embodiment, the second magnetic attraction piece 3 is directly fixed on the linkage slider 4, and is specifically fixed on the upper surface of the linkage slider 4, so as to move up and down along with the linkage slider 4; however, the design is not limited to this, in other embodiments, the second magnetic attraction piece 3 may not be directly fixed on the interlocking slide block 4, but is only pressed downward by the interlocking slide block 4, specifically, the lower surface of the second magnetic attraction piece 3 may be elastically installed in the pot cover through the first restoring piece 6, and the upper surface abuts against the interlocking slide block 4. Preferably, the first magnetic attraction piece 2 and the second magnetic attraction piece 3 are both arranged annularly, the second magnetic attraction piece 3 is movably sleeved on the exhaust valve core 11 of the pot cover, and the longitudinal projection of the first magnetic attraction piece 2 falls on the second magnetic attraction piece 3, so that a larger attraction force is formed between the first magnetic attraction piece 2 and the second magnetic attraction piece 3.
It should be noted that, in the present embodiment, the form of the first magnetic attraction member 2 and the second magnetic attraction member 3 is not limited, as long as the form of the attraction force can be formed, for example, the first magnetic attraction member 2 is a magnet, and the second magnetic attraction member 3 is a magnetic metal sheet; or, the first magnetic part 2 is a magnetic metal sheet, and the second magnetic part 3 is a magnet; or, the first magnetic part 2 and the second magnetic part 3 are both magnets, and the magnetic poles of the two magnets are opposite.
In this embodiment, the interlocking sliding block 4 preferably has a first end 41 and a second end 42 in the length direction, the second magnetic attraction piece 3 is installed at the first end 41, and the locking structure is disposed adjacent to the first end 41; the pressure adjusting key 5 is located above the second end 42, and presses the second end 42 downward to press the interlocking slider 4 downward as a whole.
In this embodiment, the first restoring member 6 can restore the interlocking slider 4 and the second magnetic attraction member 3 from the first low position or the second low position to the high position, or can restore the interlocking slider 4 and the second magnetic attraction member 3 from the second low position to the first low position. Moreover, the first reset piece 6 can be flexibly designed according to practical conditions, and simply, the first reset piece 6 can be set to be a compression spring.

Because the high level, first low level and the low level of second highly reduce in proper order, inhale in the second promptly and be located in proper order when high level, first low level and second low level, the second is inhaled the distance of inhaling between piece 3 and the first magnetism and is inhaled the piece 2 and increase in proper order, consequently, inhale in the second magnetism and inhale piece 3 and be located in proper order when high level, first low level and second low level, the second is inhaled the piece 3 and is inhaled the suction that piece 2 formed with first magnetism and reduce in proper order. The first magnetic attraction piece 2 is fixedly arranged on the exhaust valve 10, and the exhaust pressure of the pressure cooker is the superposition of the gravity of the exhaust valve 10 and the attraction between the second magnetic attraction piece 3 and the first magnetic attraction piece 2, so that the exhaust pressure of the pressure cooker is reduced sequentially when the second magnetic attraction piece 3 is positioned at the high position, the first low position and the second low position sequentially. Thus, when the second magnetic attraction piece 3 is at the high position, the pressure cooker has a certain exhaust pressure; the linkage slide block 4 is pressed downwards through the pressure regulating key 5, so that the second magnetic suction piece 3 is driven to the first low position, and when the linkage slide block 4 is blocked by the lock catch structure to move upwards to limit the second magnetic suction piece 3 at the first low position, the pressure cooker has the exhaust pressure of the other size; the linkage slide block 4 is pressed downwards through the pressure regulating key 5, the second magnetic suction piece 3 is driven to the second low position, and when the linkage slide block 4 is blocked by the lock catch structure to move upwards to limit the second magnetic suction piece 3 at the second low position, the pressure cooker has the exhaust pressure of the other size; in other words, the technical scheme can lead the pressure cooker with the pressure regulating mechanism to have a plurality of exhaust pressures through the matching of the pressure regulating key 5 and the locking structure, thereby realizing the multi-stage pressure regulation of the pressure cooker.
It should be noted that, in the present invention, the second magnetic attraction piece 3 may further have a third low position lower than the second low position, a fourth low position lower than the third low position, and the like, so as to realize more-stage pressure adjustment of the pressure cooker, which is not limited in the present invention.

In this embodiment, the locking structure is the inner end of the self-locking slider 7 of the pot cover, and the interlocking slider 4 is locked with the inner end of the self-locking slider 7 when being pressed. The self-locking sliding block 7 is elastically and movably arranged on the pot cover and can stretch and move towards the center direction of the pot cover; specifically, the outer end of the self-locking slider 7 is provided with an opening stop portion 71, the outer side of the opening stop portion 71 is provided with a second reset piece 72, and the second reset piece 72 is used for making the self-locking slider 7 have a tendency of extending inwards towards the center of the pot cover. The lateral wall face of the pressure cooker body (not shown) and the upper end that is close to the pressure cooker body are equipped with a plurality of pot teeth (not shown), the pot cover lid closes the last port setting of the pressure cooker body, and the height at the portion of stopping opening 71 and pot teeth roughly equals, when the pot cover rotates relative to the pressure cooker body and uncaps, pot teeth can support the inboard of stopping opening 71 to make auto-lock slider 7 outwards remove, and make the inner of auto-lock slider 7 stagger at the horizontal direction with interlock slider 4, thereby make interlock slider 4 unbuckled, and then interlock slider 4 and second magnetism inhale piece 3 and can reset to under the effect of first piece 6 that resets high position.
It should be noted that in this embodiment, the tripping action between the inner end of the self-locking slider 7 and the interlocking slider 4 is realized by the extension and retraction of the self-locking slider 7; however, the design is not limited to this, in other embodiments, when the locking structure is a locking protrusion fixed in the pot cover, the interlocking slide block 4 may be a slide piece with an elastic sliding margin in the horizontal direction, and the horizontal elastic sliding of the interlocking slide block 4 itself may be used to realize the releasing action between the interlocking slide block 4 and the locking protrusion.
In addition, it should be emphasized that the following description specifically exemplifies the inner end of the self-locking slider 7 with the locking structure as the lid.
Furthermore, a blocking structure is formed at one end of the linkage sliding block 4 close to the inner end of the self-locking sliding block 7. In this embodiment, the blocking structure includes a blocking protrusion 43 extending from the interlocking slider 4 to the inner end of the self-locking slider 7, and a first locking groove 431 disposed on the end surface of the free end of the blocking protrusion 43. In this embodiment, when the second magnetic element 3 is at the high position, the inner end of the self-locking slider 7 is located below the blocking protrusion 43, and is overlapped with the blocking protrusion 43 in the up-down direction; when the pressure regulating key 5 presses the linkage slide block 4 downwards to drive the second magnetic attraction piece 3 to the first low position, the inner end of the self-locking slide block 7 is inserted into the first locking groove 431 to block the linkage slide block 4 from moving upwards, so that the second magnetic attraction piece 3 is limited to the first low position; when the pressure-adjusting key 5 presses the linkage slider 4 to drive the second magnetic-attracting element 3 to the second low position, the inner end of the self-locking slider 7 is lapped on the upper surface of the blocking bump 43 to block the linkage slider 4 from moving upwards, so that the second magnetic-attracting element 3 is limited to the second low position. It should be noted that, in the present embodiment, the first locking groove 431 is recessed on the blocking protrusion 43; however, in other embodiments, the first locking groove 431 may also be directly recessed on the side of the interlocking slider 4 facing the inner end of the self-locking slider 7. In addition, in order to realize more stages of pressure regulation of the pressure cooker, more than two first locking grooves 431 (as shown in fig. 3) may be provided at intervals in the vertical direction on the free end surface of the blocking projection 43.
