As shown in fig. 1 to 7, the exhaust assembly of the present embodiment includes: the device comprises a fixed part 10, a base 20, a movable part 30, a key structure 40 and a lever structure 50. Wherein, the fixing member 10 comprises a fixing plate 11, and the fixing plate 11 is provided with a first through hole 111; the base 20 is disposed below the fixing plate 11 and has a second through hole 21 disposed opposite to the first through hole 111; the movable piece 30 is movably arranged between the base 20 and the fixed plate 11, the movable piece 30 is positioned at the outer side of the circumference of the second through hole 21, and the movable piece 30 comprises a first guide wall 321 which is gradually inclined inwards from bottom to top; the key structure 40 comprises a key 41, a reset piece 42 arranged at the bottom of the key 41 and a limiting protrusion 43 arranged on the side wall of the key 41, wherein the limiting protrusion 43 is arranged in a telescopic manner in the radial direction of the key structure 40, and the key structure 40 is movably arranged in the first through hole 111 and the second through hole 21 in a penetrating manner in the vertical direction; the lever structure 50 is disposed below the base 20, and a first end of the lever structure 50 is located below the reset element 42; the exhaust pipe 70 and the pressure limiting valve 80, the exhaust pipe 70 penetrates through the cover body, the pressure limiting valve 80 is arranged at the top of the exhaust pipe 70, and the second end of the lever structure 50 is in driving fit with the pressure limiting valve 80; the key structure 40 has an initial position, a locking position and a reset position from top to bottom, when the key 41 is located at the initial position, the limiting protrusion 43 is located above the fixing plate 11, the reset piece 42 is in an original length, and a gap is formed between the bottom of the reset piece 42 and the first end of the lever structure 50; when the key 41 is located at the locking position, the limiting protrusion 43 is located below the fixed plate 11 and is in stop fit with the fixed plate 11, and the reset piece 42 is in abutting fit with the first end of the lever structure 50; when the key 41 is at the reset position, the limiting protrusion 43 is located below the first guiding wall 321 of the movable member 30; when the key 41 is located at the reset position and is not subject to external force, the key 41 can be reset from the reset position to the initial position under the action of the reset member 42 and the guidance of the first guide wall 321.

With the technical solution of the present embodiment, the key 41 is movably disposed in the base 20 and the fixing member 10, and has an initial position, a locking position, and a reset position. When the key 41 is located at the initial position (as shown in fig. 1 and 2), the limiting protrusion 43 is located above the fixing plate 11, the restoring member 42 is in an original length, and a gap is formed between the bottom of the restoring member 42 and the first end of the lever structure 50, at this time, the driving end of the key 41 is not in driving fit with the lever structure 50, and at this time, the cooking apparatus is in a non-working state or a pressure cooking state. When pressure release and exhaust are needed, a user can press the key 41 downwards to enable the key 41 to move from an initial position to a locking position, at the moment, the limiting protrusion 43 is contracted inwards under the action of the extrusion force of the hole wall of the first through hole 111, passes through the first through hole 111 and then is located below the fixing plate 11 (as shown in fig. 4), at the moment, the limiting protrusion 43 protrudes out of the side wall of the key 41 under the action of the self elastic restoring force, and the fixing plate 11 can form a stop for the limiting protrusion 43, so that the key 41 can be abutted against the lower surface of the fixing plate 11 under the action of the restoring force of the restoring piece 42 and kept at the locking position. The key 41 located at the locking position can enable the first end of the lever structure 50 to move downwards, so that the second end of the lever structure 50 drives the pressure limiting valve to move to the exhaust position, and pressure release and exhaust of the cooking utensil are achieved. After the pressure release and the exhaustion are completed, the user presses the key 41 again, so that the key 41 moves from the locking position to the reset position, in this process, the limiting protrusion 43 on the key 41 presses the movable member 30 downwards first and moves to the lower side of the movable member 30 beyond the movable member 30, when the user stops pressing the key 41, the key 41 can move upwards under the action of the reset force of the reset member 42 and drives the movable member 30 to move upwards, at this moment, the limiting protrusion 43 can shrink inwards under the guiding action of the first guiding wall 321, so that the limiting protrusion 43 can smoothly pass through the first through hole 111 and return to the initial position (as shown in fig. 7 and 2), at this moment, the first end of the lever structure 50 loses the driving action of the key 41 and does not push the pressure limiting valve any more, and thus the pressure limiting valve falls back to the blocking position. The key structure has low processing precision requirement, is convenient to design and convenient to operate, and the limit protrusions 43 and the fixed plate 11 or the movable piece 30 form sliding fit of lines and surfaces in the moving process of the keys 41, so that the probability of occurrence of a clamping phenomenon can be effectively reduced, and the use experience of a user is improved.

In addition, since the stroke of the key 41 from the initial position to the reset position is long, if the lever structure 50 is directly driven by the key 41, a sufficiently large longitudinal movement space is required for the first end of the lever structure 50, and a limited space in the cover 60 is occupied. This application sets up the piece that resets 42 in the bottom of button 41, and when button 41 moved down, the piece that resets 42 also can be compressed in the time of moving down to on the one hand can give lever structure 50 with the driving force transmission of button 41, on the other hand can share the decurrent stroke of a part button 41 through the compression volume of piece that resets 42 self, reduces the required vertical activity space of lever structure 50, thereby is favorable to the miniaturized design of lid.

It should be noted that, when the restoring member 42 is in the original length, the gap between the bottom of the restoring member 42 and the first end of the lever structure 50 is between 0.1mm and 5 mm.

It should be noted that, in this embodiment, when the restoring member 42 is in the original length, the restoring member may also be attached to the first end of the lever structure 50, that is, the restoring member 42 does not apply an elastic force to the lever structure 50 when in the original length, so that the second end of the lever structure 50 is kept away from the pressure limiting valve.

As shown in fig. 2, 4, 5 and 6, in the present embodiment, the movable member 30 includes an elastic member 31 provided on the base 20 and a movable block 32 provided on top of the elastic member 31, the movable block 32 has a compressed position and a start position, the first guide wall 321 is located on a side wall of the movable block 32, when the key 41 is located at the lock position, the movable block 32 is located at the start position, and the limit protrusion 43 is located between the fixed plate 11 and the movable block 32; the base 20 further comprises a limiting table 22 arranged between the second through hole 21 and the elastic piece 31, and the limiting table 22 is positioned outside the limiting protrusion 43 and can be in abutting fit with the first guide wall 321; when the key 41 moves from the locking position to the reset position, the limiting protrusion 43 drives the movable block 32 to move downwards, and when the key 41 is located at the reset position, the movable block 32 moves to the outer side of the limiting protrusion 43 under the driving of the limiting protrusion 43 and the guiding action of the limiting table 22, so that the movable block 32 is reset to the initial position under the action of the elastic piece 31.

In the above structure, the movable block 32 is connected to the base 20 through the elastic member 31, and the base 20 is provided with the stopper 22 guiding and cooperating with the movable block 32. After the pressure release and the air release are finished, a user presses the key 41 downwards to enable the key to move from the locking position to the reset position, in the process of moving the key 41 from the locking position to the reset position, the limiting protrusion 43 of the key 41 downwards moves to drive the movable block 32 to move from the initial position to the compression position, when the key 41 moves to the reset position, the first guide wall 321 of the movable block 32 is stopped by the limiting table 22 and moves outwards under the pushing action of the limiting protrusion 43 until the movable block 32 is separated from the pressing of the limiting protrusion 43 and returns to the initial position under the action of the elastic restoring force of the elastic piece 31, at this time, the user stops pressing the key 41, the key 41 moves from the reset position to the initial position under the action of the restoring force of the restoring piece 42, in the process of moving upwards the key 41, the limiting protrusion 43 can abut against the first guide wall 321 of the movable block 32 located at the initial position and drive the movable block 32 to incline upwards, so that the first guide wall 321 of the movable block 32 extends towards the first through hole 111, the limiting protrusion 43 can shrink inwards under the action of the first guide wall 321 and the restoring force of the restoring piece 42, and the restoring force of the restoring piece 42 moves inwards from the first guide wall 321 to the initial position to the first through hole 111 when the restoring force of the restoring piece 42 is separated from the first guide wall 321 and enters the initial position to the initial position from the first guide wall 111. The above structure enables the limit protrusion 43 to automatically move from the reset position back to the initial position after the user presses the key 41 to the reset position, thereby facilitating the user operation.

As shown in fig. 2, 4, 5, 6 and 10, in the present embodiment, the top wall of the limiting table 22 includes a stop wall 221 that is in stop fit with the key 41 and a second guide wall 222 that is in stop fit with the first guide wall 321. In the above structure, when the key 41 moves to the reset position, the limiting protrusion 43 can be in abutting fit with the stop wall 221 of the limiting table 22, so as to give a hand feeling prompt that the key 41 has been pressed to the reset position to the user, and improve the use experience of the user. The second guiding wall 222 is in guiding engagement with the first guiding wall 321 of the movable block 32, so that the movable block 32 can smoothly move outwards when being pressed to the compression position, and smoothly returns to the initial position beyond the limit protrusion 43.

Preferably, the lowest point of the stop wall 221 may be located below the highest point of the second guide wall 222, so that before the movable block 32 moves to the lowest position of the stop wall 221, the movable block 32 moves to the outer side of the limiting protrusion 43 under the guiding action of the second guide wall 222, so that the movable block 32 rebounds upward before the limiting protrusion 43, and when the key 41 moves from the reset position to the initial position, the key 41 can contact with the movable block 32, so that the limiting protrusion 43 contracts inward under the guiding action of the movable block 32, and smoothly passes through the first through hole 111 and returns to the initial position.

It should be further noted that, when the user presses the key 41 from the initial position to the locked position, the limiting protrusion 43 will rebound rapidly after being separated from the first through hole 111, and this process gives the user feedback feel, so that the user knows that the key 41 has moved to the locked position. Accordingly, when the user moves the key 41 from the lock position to the reset position, the stopper protrusion 43 can abut against the stopper wall 221, thereby giving the user a feel feedback that the key 41 has been moved to the reset position.

As shown in fig. 5 and 6, in the present embodiment, the elastic member 31 is a spring, the base 20 is provided with a first mounting groove 23 fixedly connected to the bottom end of the spring, and the movable block 32 is provided with a second mounting groove 322 fixedly connected to the top end of the spring. Specifically, the first mounting groove 23 and the second mounting groove 322 are annular grooves, and one end of the elastic member 31 extends into the first mounting groove 23 and the other end extends into the second mounting groove 322. In the above structure, since the movable block 32 moves to the outside of the limit protrusion 43 when the movable block 32 is at the compressed position, the top and bottom ends of the elastic member 31 are displaced in the radial direction thereof, and the elastic member 31 is connected in such a manner that the elastic member 31 is stably connected between the base 20 and the movable block 32.

As shown in fig. 2, 7 and 10, in the present embodiment, when the movable block 32 is located at the start position, the distance L1 between the inner edge of the movable block 32 and the axis of the key 41 is smaller than the distance L2 between the wall of the first through hole 111 and the axis of the key 41. In the above structure, when the key 41 moves from the reset position to the initial position under the action of the reset force of the reset member 42, during the process of moving the key 41 upward, the limiting protrusion 43 can abut against the first guiding wall 321 of the movable block 32 located at the initial position and drive the movable block 32 to incline upward, so that the first guiding wall 321 of the movable block 32 extends toward the first through hole 111. In order to ensure that the limit protrusion 43 can be smoothly guided into the first through hole 111 after the movable block 32 is inclined, when the movable block 32 is located at the initial position, the inner edge of the movable block 32 needs to protrude out of the hole wall of the first through hole 111 (that is, the distance L1 between the inner edge of the movable block 32 and the axis of the key 41 is smaller than the distance L2 between the hole wall of the first through hole 111 and the axis of the key 41), so that when the movable block 32 is inclined, the first guide wall 321 can smoothly guide the limit protrusion 43 into the first through hole 111, thereby reducing the probability that the limit protrusion 43 is clamped below the fixed plate 11 and enabling the key 41 to smoothly return to the initial position.

As shown in fig. 2, 4 and 9, in the present embodiment, the first through hole 111 includes a third guide wall 1111 that gradually slopes inward from top to bottom.
