It will be appreciated that the cover 10 is intended for use with cooking apparatus, for example with cooking apparatus such as rice cookers, pressure cookers, electric steamers, steam cookers, and the like. Wherein, the cooking apparatus may further have a cooking pot 20 in addition to the cover body 10, and the cover body 10 is adapted to cover the cooking pot 20 and enclose a cooking cavity with the cooking pot 20. Wherein, the cover 10 has a valve body assembly 510, the valve body assembly 510 is adapted to limit the pressure of the cooking cavity, limit the pressure in the cooking cavity below the pressure limit pressure corresponding to the corresponding position (or gear) of the valve body assembly 510, or is adapted to limit the pressure of the space (such as the exhaust channel 521 of the valve core 520) communicated with the cooking cavity.

It can be understood that the initial position may be any position within the movement range of the pressure regulating toggle member 200, and a person skilled in the art can flexibly select a certain position within the movement range of the pressure regulating toggle member 200 as the initial position according to requirements, so that the pressure regulating toggle member 200 returns to the initial position each time it is reset, or the pressure regulating toggle member 200 moves from the initial position when it is pressure regulated.

For example, the pressure regulating toggle member 200 is suitable for switching the pressure limiting pressure among no pressure, low pressure and high pressure, wherein the pressure regulating toggle member 200 may be at a high pressure corresponding to the pressure limiting pressure at an initial position, and of course, the pressure regulating toggle member 200 may be at any other pressure value corresponding to the pressure limiting pressure at the initial position according to a requirement, such as no pressure or low pressure. And it is understood that pressureless can be understood as atmospheric pressure, and low pressure and high pressure are relatively two pressures, and it is understood that the pressure value of low pressure is higher than that of high pressure.

Specific example one: the cover 10 further includes a valve body assembly 510 and an exhaust passage 521; the valve body assembly 510 is used for opening or blocking the exhaust channel 521, wherein the pressure regulating toggle member 200 is connected to the valve body assembly 510, the pressure regulating toggle member 200 is rotatable relative to the cover body 100, and the pressure regulating toggle member 200 is configured to change the pressure limiting pressure of the valve body assembly 510 to the exhaust channel 521 by rotating the linkage valve body assembly 510. Like this, dial through rotating the pressure regulating and can dial the piece 200 and be to the corresponding adjustment of voltage limiting pressure, use easy operation convenience, and dial when the pressure regulating and to be moved 200 and reset by the driving piece drive that resets, can be corresponding make valve body assembly 510 reset to realize valve body assembly 510's automatic re-setting and adjust, avoided the user to forget to have food culinary art effect not good, the hot water juice spills over bad situation such as when adjusting that resets, the use of product is experienced better.

Further, when the valve body assembly 510 rotates, the weight applied to the exhaust channel 521 by the valve body assembly 510 changes, thereby achieving the purpose of changing the pressure limiting pressure of the cooking cavity of the cooking apparatus.

Further, the valve body assembly 510 includes an outer valve body 511 and an inner valve body 512 which are connected to each other, the pressure regulating dial 200 is connected to the outer valve body 511, and the pressure regulating dial 200 rotates to drive the outer valve body 511 to ascend or descend relative to the exhaust passage 521, so as to change the weight of the valve body assembly 510 fitted on the exhaust passage 521.

Specifically, for example, as shown in fig. 2 and 14, the valve body assembly 510 specifically includes an outer valve body 511 and an inner valve body 512, and the outer valve body 511 is connected to the pressure regulating toggle member 200 and rotates with the pressure regulating toggle member 200.

For example, the pressure regulating toggle member 200 has an annular body, which is sleeved outside the outer valve body 511, and one of the outer surface of the side wall of the annular body and the inner surface of the side wall of the annular body is provided with teeth, and the other is provided with tooth grooves, and the teeth are engaged with the tooth grooves, so that the outer valve body 511 rotates with the pressure regulating toggle member 200, and the teeth can slide along the tooth grooves, so that the outer valve body 511 and the annular body can move up and down relatively. When the pressure regulating toggle member 200 rotates, the outer valve body 511 can be raised or lowered relative to the pressure regulating toggle member 200. Of course, the embodiment is not limited to this, and the pressure regulating toggle member 200 may be designed to move up and down along with the outer valve body 511 according to the requirement.

As shown in fig. 16, the inner valve body 512 is provided with a blocking portion 513, and the blocking portion 513 is used to close or open the exhaust passage 521.

For example, the cap body 100 is provided with a valve core 520, and the valve core 520 defines an exhaust channel 521 therein. Specifically, when the blocking portion 513 is pressed against the valve core 520, the blocking portion 513 seals the exhaust passage 521 of the valve core 520, and when the inner valve body 512 is lifted up so that the blocking portion 513 opens the exhaust passage 521, the cooking chamber can be exhausted along the exhaust passage 521.

When the pressure regulating toggle member 200 rotates, the outer valve body 511 rotates and rises, after the outer valve body 511 rises, the weight of the outer valve body 511 is borne by the face cover 110 of the cover body 100 and is not pressed on the exhaust port of the valve core 520, so that only the weight of the inner valve body 512 is pressed on the exhaust port of the valve core 520, and therefore the inner valve body 512 can be pushed to exhaust when the pressure in the cooking cavity of the cooking device is low, and low-pressure cooking is realized.

When the pressure regulating toggle member 200 continues to rotate, the outer valve body 511 rotates and continues to rise, the outer valve body 511 jacks up the inner valve body 512, for example, the flexible body 5112 (specifically, a silicone body, a rubber body, etc.) of the outer valve body 511 jacks up the inner valve body 512, the outer valve body 511 and the inner valve body 512 are not pressed on the exhaust port of the valve core 520, the exhaust passage 521 is opened, and non-pressure cooking is realized.

When the outer valve body 511 is reset under the driving of the pressure regulating toggle piece 200, the outer valve body 511 descends, the outer valve body 511 is pressed on the inner valve body 512, specifically, for example, the limiting protrusion 5111 of the outer valve body 511 is pressed on the limiting block 5121 of the inner valve body 512, so that the weights of the inner valve body 512 and the outer valve body 511 are both pressed on the exhaust port of the valve core 520, therefore, the pressure in the cooking cavity of the cooking equipment is higher, the inner valve body 512 can be pushed to exhaust, high-pressure cooking is realized, the weight of the valve body assembly 510 pressed on the exhaust port of the valve core 520 is changed, and the purpose of adjusting the pressure change of the cooking cavity in the cooking equipment is realized.

For example, as shown in fig. 15, the cover body 100 is provided with a support column 113. Such as the support posts 113 provided on the face cover 110 of the cover body 100. The outer valve body 511 is provided with a pressure regulating surface 530, the supporting column 113 abuts against the pressure regulating surface 530, and the outer valve body 511 rotates to change the abutting position of the pressure regulating surface 530 and the supporting column 113, so that the lifting height of the outer valve body 511 is regulated.

Specifically, as shown in fig. 15, the voltage-regulating surface 530 includes a first-stage voltage-regulating plane 531, a second-stage voltage-regulating plane 532, a third-stage voltage-regulating plane 533, a first voltage-regulating slope 534 and a second voltage-regulating slope 535, where the first voltage-regulating slope 534 transits between the first-stage voltage-regulating plane 531 and the second-stage voltage-regulating plane 532, the first voltage-regulating slope 534 rises from the first-stage voltage-regulating plane 531 to the second-stage voltage-regulating plane 532, and the second voltage-regulating slope 535 rises from the second-stage voltage-regulating plane 532 to the third-stage voltage-regulating plane 533.

When the supporting column 113 abuts against the third stage pressure regulating plane 533, the pressure regulating toggle 200 is at the initial position, and the valve body assembly 510 is at the lowest position, and high pressure cooking is performed in the cooking cavity;

when the support column 113 abuts against the second-stage pressure regulating plane 532, low-pressure cooking is performed in the cooking cavity;

when the support column 113 abuts against the first-stage pressure regulating plane 531, the valve body assembly 510 is at the highest position, and pressureless cooking is performed in the cooking cavity.

Through this scheme, and through this structure, when realizing that outer valve body 511 rotates and forms the up-and-down motion and carry out the purpose that the pressure limiting pressure adjusted, the pressure limiting process of interior valve body 512 is not influenced basically, and the pressure limiting process is more accurate reliable, and rotates in order to carry out the up-and-down motion linkage through valve body subassembly 510, realizes valve body subassembly 510 counter weight and adjusts, and whole simple structure changes, and also makes things convenient for valve body subassembly 510 whole to tear out the washing, and daily use is more convenient.
