As shown in fig. 2,3 and 6 and 7, a cooking apparatus of the present embodiment includes a pot body 10, an exhaust pipe 30 of a pot cover 20, an exhaust valve 40 and an exhaust pushing structure 50. Wherein, the pot body 10 is used for containing food to be cooked, and the pot body 10 is provided with pot teeth. The pot cover 20 is arranged on the pot body 10, the pot cover 20 comprises a pot cover main body 21 and a steel cover 22 rotatably arranged on the pot cover main body 21, and cover teeth are arranged on the steel cover 22 and are matched with the pot teeth. The steel cover 22 has a locked position and an unlocked position, and when the steel cover 22 is in the locked position, the teeth and the teeth lock each other. When the steel cover 22 is in the unlocked position, the teeth and the cover teeth are separated from each other. An exhaust pipe 30 is provided on the steel cover 22 and communicates with the cooking space in the pot body 10, and an exhaust valve 40 is provided on the exhaust pipe 30. The exhaust pushing structure 50 is provided on the steel cover 22. Wherein, a guiding and matching structure 60 is arranged in the pot cover main body 21, and when the steel cover 22 rotates from the locking position to the unlocking position, the guiding and matching structure 60 is horizontally matched with the exhaust pushing structure 50 and drives the exhaust pushing structure 50 to act, so that the exhaust pushing structure 50 pushes the exhaust valve 40.

By applying the technical scheme of the embodiment, since the guiding and matching structure 60 and the exhaust pushing structure 50 are horizontally matched, even if the steel cover 22 is pushed upwards by steam, the guiding and matching structure 60 and the exhaust pushing structure 50 are not separated, and the exhaust pushing structure 50 always pushes the exhaust valve 40, so that the stability of the function of opening the cover and exhausting is ensured. Therefore, the technical scheme of the embodiment solves the problem that the cover opening and exhausting functions of the electric pressure cooker in the prior art are easy to lose effectiveness.

It should be noted that, as can be seen from fig. 2, the pot cover 20 of the cooking apparatus of the present embodiment is provided with a cover opening handle, and the user rotates the cover opening handle to drive the steel cover 22 to rotate synchronously. When the user rotates the cover opening handle to the cover closing position, the steel cover 22 synchronously rotates to the locking position, and at this time, the user cannot open the pot cover 20 even pressing the unlocking button, so that the safety of cooking is ensured. When the user rotates the cover opening handle to the cover opening position after cooking is finished, the steel cover synchronously rotates to the unlocking position, and at the moment, the pot teeth and the cover teeth are separated, so that the user can normally open the cover. In this process, the exhaust pushing structure 50 and the steel cover 22 rotate synchronously, and the guiding and matching structure 60 and the exhaust pushing structure 50 are horizontally matched, so that the exhaust pushing structure 50 pushes the exhaust valve 40, thereby realizing the function of uncovering and exhausting.

As shown in fig. 4 and 5, in the technical solution of the present embodiment, the exhaust pushing structure 50 is an exhaust lever, a first end of the exhaust lever is matched with the exhaust valve 40, and a second end of the exhaust lever is matched with the guiding matching structure 60. Specifically, the exhaust lever is rotatably provided on the steel cover 22. When the steel cap 22 is rotated, the guide engagement structure 60 engages the second end of the exhaust lever engagement and urges the exhaust lever to swing. The exhaust lever pushes the exhaust valve 40 at the first end of the exhaust lever after swinging, thereby achieving the purpose that the exhaust lever pushes the exhaust valve 40.

Of course, the exhaust pushing structure 50 is not limited to the exhaust lever structure, and other rotating and sliding structures may be used. Such as a slider structure, a swing link structure, a cam structure, etc.

As shown in fig. 5, in the technical solution of the present embodiment, the second end of the exhaust lever is provided with a mating surface 51 extending in the vertical direction, and when the steel cover 22 rotates from the locking position to the unlocking position, the guiding mating structure 60 pushes the mating surface 51 and drives the exhaust lever to swing, so that the first end of the exhaust lever pushes the exhaust valve 40. Specifically, since the mating surface 51 is a surface extending vertically, the guide mating structure 60 applies a force in a horizontal direction to the exhaust lever when pushing against the mating surface 51, thereby pushing the exhaust lever to swing. Preferably, the length of the mating surface 51 in the vertical direction should satisfy the following condition: the length should be at least not smaller than the distance that the steel lid 22 moves relative to the lid body 21 when the steel lid 22 is pushed by steam, so as to ensure that the push-fit surface 51 of the guide-fit structure 60 is always in contact when the steel lid 22 is in the unlocked position. It should be noted that, regarding the above-mentioned "distance the steel lid 22 moves relative to the lid body 21 when the steel lid 22 is pushed by steam", the value thereof varies according to the structure of the product, and a person skilled in the art may perform a general experiment according to the specific structure of the product to obtain the value.

As shown in fig. 6 and 7, in the technical solution of this embodiment, an avoidance gap 211 is provided on a pot cover main body 21, and when a steel cover 22 is installed on the pot cover main body 21, an exhaust pushing structure 50 passes through the avoidance gap 211 and extends into the pot cover main body 21, and a guiding and matching structure 60 is disposed at the avoidance gap 211. Specifically, when the operator installs the steel cap 22, the exhaust lever is aligned with the escape notch 211, and then the exhaust lever is passed upward through the escape notch 211. Since the guide engaging structure 60 is disposed at the escape notch 211, the guide engaging structure 60 is mounted in place with the exhaust lever when the exhaust lever is mounted in place.

As shown in fig. 7, in the technical solution of the present embodiment, the guiding and matching structure 60 is disposed on the inner sidewall of the avoidance gap 211. Specifically, when the steel cover 22 rotates, the exhaust lever slides in the avoidance notch 211, and during the sliding process, the matching surface 51 of the exhaust lever is in abutting fit with the guiding and matching structure 60, the guiding and matching structure 60 pushes the exhaust lever to swing, and then the exhaust lever pushes the exhaust valve 40

As shown in fig. 11 and 12, the inner side wall of the avoidance gap 211 includes: the first and second inner walls 2111 and 2112 are disposed opposite each other, and the first and second connecting walls 2113 and 2114 are disposed opposite each other. Wherein the second inner wall 2112 is outboard of the first inner wall 2111; the first connection wall 2113 has both ends connected to the first end of the first inner wall 2111 and the first end of the second inner wall 2112, respectively, and the second connection wall 2114 has both ends connected to the second end of the first inner wall 2111 and the second end of the second inner wall 2112, respectively, wherein the guide fitting structure 60 is disposed on the second inner wall 2112. Preferably, the avoidance notch 211 is an arc notch because the movement track of the exhaust lever is an arc during the rotation of the steel cap 22. That is, the first inner wall 2111 and the second inner wall 2112 are arc-shaped inner walls. As can be seen in fig. 7, when the exhaust lever is installed in the avoidance gap 211, the first end of the exhaust lever faces the first inner wall 2111, the second end of the exhaust lever faces the second inner wall 2112, and the mating surface 51 of the exhaust lever is disposed corresponding to the second inner wall 2112. During the movement of the exhaust lever, the guide engagement structure 60 abuts the engagement surface 51 and pushes the exhaust lever, which in turn pushes the exhaust valve 40

As shown in fig. 6 and 7, in the technical solution of the present embodiment, the second inner wall 2112 is provided with an ejector rib 70, and the surface of the ejector rib 70 facing the first inner wall 2111 forms the guiding and matching structure 60. Preferably, the surface of the push rib 70 facing the first inner wall 2111 is arcuate. Specifically, in the direction along which the steel cover 22 is rotated from the locked position to the unlocked position, the arcuate surface is gradually raised in a gradual concave manner, i.e., the arcuate surface is a surface with a convex middle portion. As can be seen from fig. 6 to 9, during rotation of the exhaust lever, the mating surface 51 contacts the arcuate surface, and when the mating surface 51 moves to the top of the arcuate surface, the exhaust lever is pushed against the first end of the exhaust lever to lift the exhaust valve 40. At the same time, the steel cover 22 is also moved to the unlocked position. When the exhaust lever is moved to the position of fig. 9, it can be seen from fig. 10 that the ejector rib 70 ejects the exhaust lever and causes the left end of the exhaust lever to eject the exhaust valve 40.

Preferably, in this embodiment, the thickness of the ejector bead 70 is in the range of 1 to 5 millimeters and the maximum distance of the arcuate surface to the second inner wall 2112 is in the range of 1 to 8 millimeters. Specifically, the thickness of the push rib 70 refers to the distance between the upper and lower surfaces of the push rib 70 in the axial direction along the lid 20. The maximum distance of the arcuate surface from the second inner wall 2112 is the distance from the highest point of the arcuate surface protruding from the second inner wall 2112, i.e., the maximum distance, as can be seen in fig. 7.

As shown in fig. 6 and 7, in the technical solution of the present embodiment, the cooking apparatus further includes a solenoid valve 80 disposed in the pot cover main body 21, a push rod 81 of the solenoid valve 80 is matched with the exhaust pushing structure 50, and when the steel cover 22 is in the locking position, the exhaust pushing structure 50 is aligned with the push rod 81 of the solenoid valve 80. Specifically, the above structure enables the exhaust valve 40 to be normally driven and exhausted when the steel cover 22 is in the locked position. I.e. to achieve a normal exhaust during the cooking appliance. Further, as can be seen from fig. 7, a notch is provided on the left side of the second inner wall 2112, through which notch the push rod 81 extends into the avoidance notch 211. The left end of the push rib 70 extends to the notch, and the right end extends to the second connecting wall 2114.

As shown in fig. 4, in the technical solution of this embodiment, the pot cover main body 21 includes a liner 212 and a surface cover 213 disposed on the liner 212, the steel cover 22 is rotatably disposed on the lower side of the liner 212, and the avoiding notch 211 is disposed on the liner 212. Specifically, the liner 212 and the cover 213 are each provided with an evacuation port for evacuating the exhaust pipe 30. The specific assembly process of the above structure is as follows, firstly, the steel cover 22 is assembled on the lower side of the liner 212, the exhaust pipe 30 passes through the avoidance opening on the liner 212, then the face cover 213 is covered on the liner 212, the exhaust pipe 30 passes through the avoidance opening on the face cover 213, finally, the exhaust valve 40 is assembled from the upper side of the face cover 213, and the exhaust valve 40 is arranged on the exhaust pipe 30.

As shown in fig. 4 and 5, in the technical solution of the present embodiment, a mounting seat 90 is provided on the steel cover 22, and the exhaust pushing structure 50 is shown to be disposed on the mounting seat, where the exhaust pushing structure 50 includes a rotating shaft 52, a first rod 53 and a second rod 54. Wherein the spindle 52 is rotatably disposed on the mounting base 90. The first rod 53 and the second rod 54 are connected to two sides of the rotating shaft 52, and an end of the first rod 53 is matched with the exhaust valve 40. The surface of the second rod body 54 facing away from the first rod body 53 forms the mating surface 51.

As shown in fig. 5, in the technical solution of the present embodiment, the second rod 54 includes a first rod segment 541 and a second rod segment 542 connected to each other, the first rod segment 541 and the first rod segment 53 are disposed at an angle, the second rod segment 542 is perpendicular to the first rod segment 53, and the mating surface 51 is formed on the second rod segment 542. The above structure enables the mating surface 51 to extend in a substantially vertical direction when the exhaust lever is in a natural state. The above structure also makes the mating surface 51 lower than the rotating shaft 52, and ensures that the exhaust lever can normally rotate when the pushing convex rib 70 pushes the mating surface 51, and prevents the locking between the structures.

As shown in fig. 5, in the technical solution of the present embodiment, a push post 56 is disposed at an end of the first rod 53, and the push post 56 is matched with a lower end of the exhaust valve 40. Specifically, the ejector pin 56 is capable of translating the swinging motion of the first rod 53 into an approximately upward ejector and making the mechanism more reliable in operation.

In embodiments not shown, the guide engagement structure 60 and the exhaust pushing structure 50 may have other arrangements. For example, an arcuate surface is provided on the exhaust pushing structure 50. When the steel cover 22 drives the exhaust pushing structure 50 to move, the arc surface on the exhaust pushing structure 50 is matched with the guiding matching structure 60, and the exhaust pushing structure 50 is actuated. Referring to fig. 7, in a top view, the mating surface 51 may be configured as an arcuate surface, and the guiding and mating structure 60 may be a push block disposed on the second inner wall 2112, where the push block has a mating surface extending in a vertical direction (i.e., the arcuate surface on the push rib 70 and the planar surface on the mating surface 51 in the above embodiment are configured in a transposed manner). By adopting the structure, the exhaust pushing structure 50 can play a role in opening the cover during the moving process of the exhaust pushing structure, and meanwhile, the guide matching structure 60 and the exhaust pushing structure 50 can be ensured to be always contacted.

As shown in fig. 2 and 3, in the technical solution of the present embodiment, the cooking appliance is an electric pressure cooker.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
