It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

As shown in fig. 1 to 6, the cooking appliance of the present embodiment includes a pan body 10 and a cover body 20 provided to cover the pan body 10. The cover 20 includes: the cover body 21, the pressure limiting valve 31, the button assembly and the opening stop plate 32. The cover body 21 is provided with an exhaust passage 23 and a mounting hole 24 at intervals, and the wall of the mounting hole 24 is provided with a guide 25 extending in a predetermined direction. The pressure limiting valve 31 is blocked in the exhaust passage 23. The button assembly includes a button 40, an ejector 50, and a first reset member 61 disposed between the cover body 21 and the ejector 50. The push button 40 is movably disposed in the mounting hole 24 in a preset direction, the push button 50 is movably disposed in the cover body 21, the push button 40 pushes the push button 50 to move to push the pressure limiting valve 31 through the push button 50 to open the air discharge passage 23, and the first reset member 61 pushes the push button 50 to move in a direction opposite to the pressing direction to cause the pressure limiting valve 31 to block the air discharge passage 23 and reset the push button 40. The opening stop plate 32 is provided on the cover 20 and cooperates with the teeth of the pan 10 and has an extended position in abutting cooperation with the teeth and a retracted position separated from the teeth. Wherein, the button 40 is provided with a first convex-concave inclined surface portion 41 toward one end of the ejector 50, a second convex-concave inclined surface portion 54 opposite to the first convex-concave inclined surface portion 41 is provided on the ejector 50, and a driving inclined surface portion 251 is provided at the bottom end of the guide member 25. When the button 40 is pressed, the first convex-concave inclined surface portion 41 and the second convex-concave inclined surface portion 54 are in abutting fit to move the ejector 50 away from the button 40; when the driving ramp portion 251 is stopped with the second convex-concave ramp portion 54, the ejector 50 is held in a position to eject the pressure limiting valve 31 to open the exhaust passage 23. When the opening stop plate 32 moves to the extended position, the opening stop plate 32 drives the ejector 50 to move so that the driving ramp portion 251 is separated from the second convex-concave ramp portion 54, and the ejector 50 and the button 40 are reset by the guide 25 and the first reset member 61.

By applying the technical scheme of the embodiment, when manual air discharge is needed, a user can press the button 40 to drive the ejector 50, so that the ejector 50 is kept at the position where the ejector pressure limiting valve 31 opens the air discharge channel 23, and quick air discharge and then quick cover opening are realized. In the process that the cover body 20 is switched from the cover closing state (the cover teeth and the pot teeth are overlapped to keep the pot cover locked) to the cover opening state (the cover teeth of the cover body are staggered with the pot teeth of the pot body), when the opening-stopping plate 32 of the cover body 20 is positioned at the extending position, the opening-stopping plate 32 drives the ejector 50 to move, so that when the driving inclined surface part 251 is separated from the second convex-concave inclined surface part 54, the ejector 50 and the button 40 are reset under the action of the guide part 25 and the first reset part 61, the ejector 50 can be automatically reset without the operation of pressing the button 40 again, and the risk of pot overflow easily occurs when the food materials are cooked next time is reduced. Similarly, in the process of switching the cover 20 from the open cover state to the closed cover state, the ejector 50 can also be automatically reset when the opening stop plate 32 of the cover 20 is in the extended position. Therefore, the technical scheme of the embodiment effectively solves the problem that the ejector cannot be automatically reset in the cover opening and closing process. The above-described preset direction may be an up-down direction, a left-right direction, or a front-rear direction, and is determined according to the arrangement position of the mounting holes 24. The preset direction in this embodiment refers to the up-down direction.

In the present embodiment, the driving ramp portion 251 is a part of the guide 25, and of course, in the embodiment not shown in the drawings, the driving ramp portion and the guide are two members.

As shown in fig. 3 to 6 and 14 to 17, when the driving ramp portion 251 is separated from the second convex-concave ramp portion 54, the process of resetting the ejector 50 and the button 40 under the action of the guide 25 and the first resetting member 61 is specifically as follows: the first reset member 61 always applies a first reset force to the ejector 50, and when the driving ramp portion 251 is separated from the second convex-concave ramp portion 54 under the action of the first reset force, the second convex-concave ramp portion 54 rotates by a certain angle relative to the driving ramp portion 251, and the guide member 25 provided with the driving ramp portion 251 plays a role in guiding the movement of the second convex-concave ramp portion 54, so that the ejector 50 is convenient to reset. When the ejector 50 is reset, the second convex-concave inclined surface portion 54 abuts against the first convex-concave inclined surface portion 41, so that the push button 40 is reset as well. Of course, in the embodiment not shown in the drawings, the end of the opening stop plate facing the ejector is provided with an abutment inclined surface, and the ejector is driven to slide on the abutment inclined surface in the process of moving away from the button, so that the ejector moves while the second convex-concave inclined surface part rotates by a certain angle relative to the driving inclined surface part. The guide 25 of this embodiment is preferably an elongated bump.

As shown in fig. 3 to 6 and 11 to 17, the ejector 50 includes a ejector portion 51 and a stopper portion 52 that is in a non-rotational engagement with the ejector portion 51, so that no relative rotation occurs between the ejector portion 51 and the stopper portion 52, and the stopper portion 52 and the ejector portion 51 can rotate together. The second convex-concave slope portion 54 includes a first slope convex portion 541 and a second slope convex portion 542. The first inclined surface convex portion 541 is provided on the push-up portion 51, the second inclined surface convex portion 542 is provided on the stopper portion 52, and both the inclined surface of the first inclined surface convex portion 541 and the inclined surface of the second inclined surface convex portion 542 coincide with the inclined direction of the inclined surface of the driving inclined surface portion 251. Thus, when the driving bevel portion 251 alone is in abutting engagement with the first bevel lobe 541, the push top portion 51 is always urged to rotate in the direction of the rotational tendency. When the driving ramp portion 251 alone is in abutting engagement with the second ramp protrusion 542, the stopper portion 52 always has a force to rotate in the direction of the rotational tendency. When the driving bevel portion 251 is in abutting engagement with the first bevel lobe 541 and is in abutting engagement with the second bevel lobe 542, the driving bevel portion 251 drives the push top 51 to rotate in the direction of the rotation trend, and then the stop portion 52 can be driven to rotate in the direction of the rotation trend, so that the push member 50 can rotate in one direction, and the second convex-concave bevel portion 54 can rotate at a certain angle relative to the driving bevel portion 251.

Specifically, the pushing portion 51 is provided with a first rotation stop surface, and the stopper portion 52 is provided with a second rotation stop surface that is in rotation stop fit with the first rotation stop surface.

As shown in fig. 3 to 6 and 11 to 17, the second inclined surface convex portion 542 has a stop position protruding from the inclined surface of the first inclined surface convex portion 541 and a escape position of the escape guide 25, and the stop portion 52 is located on a side of the first inclined surface convex portion 541 away from the push button 40 when the second inclined surface convex portion 542 is in the escape position, and the first reset member 61 is located between the cover body 21 and the stop portion 52. When the second inclined surface convex portion 542 is at the stop position, on the one hand, the stop portion 52 can be in stop engagement with the first inclined surface convex portion 541, and when the first restoring member 61 always applies the first restoring force to the stop portion 52, the first inclined surface convex portion 541 restricts the stop portion 52 from moving in the direction opposite to the pressing direction, and prevents the stop portion 52 from moving relative to the push top portion 51, so that the second inclined surface convex portion 542 can be held at the stop position. When the button 40 pushes the first inclined surface protrusion 541 to move, the stopper 52 moves in the pressing direction simultaneously with the push top 51. On the other hand, when the driving ramp portion 251 is in abutting engagement with the first ramp protrusion 541, the second ramp protrusion 542 blocks the driving ramp portion 251, so that the pushing portion 51 is restricted from rotating in the direction of the rotation trend, and the driving ramp portion 251 cannot be separated from the second convex-concave ramp portion 54, so that the ejector 50 is maintained at a position where the ejector pressure limiting valve 31 opens the exhaust passage 23.

As shown in fig. 3 to 6 and 11 to 17, when the opening stop plate 32 drives the stop portion 52 to move away from the button 40, the second inclined convex portion 542 moves from the stop position to the escape position, the second inclined convex portion 542 no longer blocks the driving inclined surface portion 251, and the first inclined convex portion 541 continues to rotate in the direction of the rotation trend, so that the driving inclined surface portion 251 is separated from the first inclined convex portion 541 of the second convex-concave inclined surface portion 54. When the opening stop plate 32 of the cover 20 is at the retracted position, the stopper 52 moves toward the button 40 under the action of the first restoring force of the first restoring member 61, the second inclined convex portion 542 moves from the escape position to the stopper position, the second inclined convex portion 542 on the stopper 52 can be in abutting engagement with the driving inclined surface portion 251, the stopper 52 then rotates in the direction of the rotation tendency, and after the second convex-concave inclined surface portion 54 rotates at a certain angle relative to the driving inclined surface portion 251, the guide member 25 guides the movement of the stopper 52 toward the button 40, so that the ejector 50 is facilitated to realize the restoration.

As shown in fig. 3 to 6 and 11 to 17, the stopper 52 includes a stopper cylinder 521 stopper-fitted with the push top 51, and a stopper plate 522 provided on the stopper cylinder 521. The push top 51 restricts the movement of the stopper cylinder 521 in the direction opposite to the pressing direction, preventing the movement of the stopper cylinder 521 with respect to the push top 51, so that the second inclined surface protrusion 542 can be maintained at the stopper position. The second inclined boss 542 and the stopper plate 522 are provided on the outer side wall of the stopper cylinder 521 at intervals in the axial direction of the stopper cylinder 521, and one end of the opening stop plate 32 toward the stopper portion 52 is located between the second inclined boss 542 and the stopper plate 522 and is in abutting engagement with the stopper plate 522. In the process of opening and closing the cover body 20, when the opening stop plate 32 is in the extended position, the stop plate 522 directly applies a driving force to the stop plate 522 in a direction away from the button 40, so as to push the stop portion 52 to move, and the second inclined convex portion 542 is convenient to move from the stop position to the avoiding position.

As shown in fig. 3 to 6 and 11 to 17, in the present embodiment, the pushing portion 51 includes a first pushing barrel section 511 and a second pushing barrel section 512 connected to the first pushing barrel section 511, the area of the cross section of the second pushing barrel section 512 is smaller than that of the cross section of the first pushing barrel section 511, a stop surface 513 is formed between the first pushing barrel section 511 and the second pushing barrel section 512, the end of the first pushing barrel section 511 facing the button 40 can extend into the button 40, and the second pushing barrel section 512 is located at the end of the first pushing barrel away from the button 40. The first inclined surface protrusion 541 is disposed on the first ejection cylinder section 511, and the stopper cylinder 521 is sleeved on the second ejection cylinder section 512 and is capable of being in stop fit with the stop surface 513. The stop cylinder 521 is in a rotationally fixed engagement with the second ejector cylinder segment 512. Specifically, the first ejector section 511 is a first cylinder, and the second ejector section 512 is a second cylinder or square cylinder. When the second ejector section 512 is a second cylinder, the first rotation stopping surface is a longitudinal section of the second cylinder disposed on the outer side surface of the second cylinder; when the second ejector section 512 is a square cylinder, the first rotation stopping surface is at least one outer side surface of the square cylinder.

As shown in fig. 1 to 6 and 14 to 17, in the present embodiment, in the case where the lid 20 is kept in the closed lid state, the opening stop plate 32 is in the extended position, and the end of the opening stop plate 32 facing the stop portion 52 always presses the stop plate 522, so that the second inclined convex portion 542 is kept in the escape position. The button assembly further includes a second reset member 62 disposed between the cover body 21 and the push-push portion 51, and the driving ramp portion 251 is solely in abutting engagement with the first ramp portion 541 with the second ramp portion 542 maintained in the retracted position, such that the first ramp portion 541 is conveniently separated from the driving ramp portion 251 without the blocking of the second ramp portion 542 under the action of the second reset force applied to the push-push portion 51 by the second reset member 62. Meanwhile, after the push top 51 continues to rotate a certain angle in the direction of the rotation trend, the guide member guides the first inclined surface convex portion 541 towards the side wall of the first inclined surface convex portion 541, and the second reset member 62 pushes the push top 51 to move in the direction opposite to the pressing direction, so that the push top 51 is reset, and the push top 50 is reset. In this way, the cover 20 is kept in the closed state, even if the user presses the button 40 for many times, the ejector 50 can be automatically reset, and in the cooking process of the cooking appliance, even if the user presses the button 40 by mistake or the air exhaust channel 23 is intermittently exhausted, the pressure limiting valve 31 can automatically block the air exhaust channel 23, so that the risk of pot overflow is effectively reduced. Naturally, when the button 40 is always pressed, the guide 25 limits the rotation of the first inclined surface protrusion 541 toward the side wall of the first inclined surface protrusion 541, and at the same time, the first convex-concave inclined surface portion 41 is in abutting engagement with the first inclined surface protrusion 541, so that the push top 51 is prevented from moving in a direction opposite to the pressing direction under the action of the second restoring force, and the push member 50 is maintained at a position where the push pressure limiting valve 31 opens the air exhaust passage 23, so that rapid air exhaust can be realized.

As shown in fig. 3 to 6 and 14 to 17, the first restoring force applied by the first restoring member 61 to the stopper 52 is greater than or equal to the second restoring force applied by the second restoring member 62 to the push portion 51. In this way, when the end of the opening stop plate 32 facing the stopper portion 52 does not press the stopper plate 522 and the second inclined surface convex portion 542 is not at the escape position, the second inclined surface convex portion 542 can be always maintained at the stopper position by the first restoring force. The first return member 61 and the second return member 62 of the present embodiment are each preferably compression springs.
