The exhaust assembly 101 provided in this embodiment mainly realizes three functions:

1. the exhaust is controlled manually, and the manual exhaust has a self-locking function (the exhaust device is opened at the position where the exhaust sliding block 200 is in limit fit with the exhaust trigger 121), so that the exhaust state can be kept without manpower, and the manual termination can be realized (the toggle 123 is driven to be reset to the closed position);

2. the self-locking sliding block 300 is utilized to enable the exhaust device to be automatically closed for resetting in the screwing process of the pot cover 1021, so that the problem that the cooking cavity cannot be pressurized when the exhaust device is forgotten to be manually closed and reset during manual exhaust is solved;

3. by using the floating member 400, when the lid 1021 is at the unscrewing position, the exhaust valve 110 is in the exhaust state, so that the lid 1021 presses the lid to close, thereby preventing the lid from closing unsmoothly due to the increase of the pressure in the cooker, for example, avoiding the problem of unsmoothly closing the lid when closing the lid in the hot state.

The working principle is as follows:

as shown in fig. 2 and fig. 3, in the initial state of the exhaust assembly 101, the protrusion 1232 of the toggle member 123 is located between the exhaust push rod 1211 and the reset push rod 1221, at this time, the exhaust push rod 1211 and the reset push rod 1221 are located at the upper limit position, the moment arm 132B of the lever 131 is located right below the exhaust push rod 1211, the lever 131 is in the horizontal state, the exhaust valve 110 is closed, and the lower end side surfaces of the exhaust push rod 1211 and the reset push rod 1221 are directly opposite to the front end of the exhaust slider 200.

As shown in fig. 4 and 5, in the exhaust state of the exhaust assembly 101 (exhaust is controlled by the toggle member 123), the toggle member 123 slides to the exhaust position, and at this time, the protrusion 1232 is located at the side where the exhaust push rod 1211 is located, and the protrusion 1232 pushes the exhaust push rod 1211 to move downwards. When the exhaust push rod 1211 moves downwards, the exhaust push rod 1211 drives the force arm 132B of the lever 131 to move downwards, and when the exhaust push rod 1211 is at the lower limit position, the rotation angle of the lever 131 is maximum, and the exhaust valve 110 reaches the maximum opening degree. In addition, during the downward movement of the exhaust push rod 1211, the exhaust push rod 1211 drives the exhaust slider 200 to move backward to compress the slider elastic member 220, when the lower end inclined surface of the second clamping portion 12113 of the exhaust push rod 1211 is located below the first clamping portion 210 of the exhaust slider 200, the exhaust slider 200 is driven by the slider elastic member 220 to move back to the first position for resetting, and the exhaust push rod 1211 is pressed after the exhaust slider 200 moves back to form an exhaust self-locking function, so as to maintain the opening of the exhaust valve 110.

As shown in fig. 6, 7 and 8, when the exhaust assembly 101 is in a closed state (closed is controlled by the toggle element 123), the toggle element 123 slides to a closed position, and at this time, the protrusion 1232 is located at one side of the reset push rod 1221, and the protrusion 1232 pushes the reset push rod 1221 to move downwards, and during the downward movement of the reset push rod 1221, the lower end side slope of the reset push rod 1221 pushes the exhaust slider 200 to move backwards to compress the slider elastic element 220, and when the exhaust slider 200 moves to the second position, the exhaust push rod 1211 and the exhaust slider 200 are tripped to release the limit fit, and at this time, the exhaust push rod 1211 moves upwards under the elastic driving of the exhaust push rod elastic element 1212 to perform automatic reset, and accordingly, as the pressing action of the exhaust push rod 1211 on the force arm 132B is released, the sealing element control lever 131 resets, and further closes the exhaust valve 110. Since the lower end of the reset push rod 1221 cannot form self-locking with the exhaust slider 200, after the toggle member 123 leaves the closed position, the reset push rod 1221 moves upward under the elastic action of the reset push rod elastic member 1222 to automatically reset, so that the exhaust slider 200 is further automatically reset to recover the initial state.

As shown in fig. 9 and 10, which are schematic structural diagrams of automatic resetting of the exhaust assembly 101 (closing of the exhaust valve 110 of the exhaust assembly 101) in the process of screwing the lid 1021 of the upper cover 102, in the manual exhaust state, when the exhaust push rod 1211 is at the lower limit position, the force arm 132B of the lever 131 is pressed down, the exhaust valve 110 is opened, the exhaust slider 200 locks the exhaust push rod 1211, at this time, when the lid 1021 of the upper cover 102 is rotated, the self-locking pin 310 on the self-locking slider 300 cooperates with the pot teeth 21 of the outer pot 23 to drive the self-locking slider 300 to move backward, the self-locking slider 300 is connected with the exhaust slider 200, and the exhaust slider 200 is linked to move backward in the process of moving backward the self-locking slider 300 so that the exhaust push rod 1211 unlocks and resets, as shown in fig. 10, when the self-locking slider 300 slides from one side of a pot.

As shown in fig. 14, which is a schematic structural view of the automatic exhaust of the exhaust assembly 101 when the exhaust assembly 101 is in the unscrewed position, the lower end of the top rod 420 of the floating member 400 extends out of the surface cover 1022, when the upper cover 102 is placed on the pot body 20, the lower end surface of the push rod 420 is in contact with the surface of the housing cover 22, and directly below the push rod 420 is an adapter 440 on the housing cover 22, wherein, the adapting part 440 is a boss structure, and the top end of the boss structure is transited to the surface of the housing cover 22 by the guiding inclined surface 441, at this time, the lower end of the push rod 420 is pressed on the boss structure, when the upper cover 102 rotates towards the direction close to the unscrewing position relative to the pot body 20, the push rod 420 slides upwards along the guide inclined plane 441, wherein, the upper end of the floating member 400 is matched with the rear end of the exhaust slider 200 to form a sliding pair, and drives the air-discharge slider 200 to move backward (drives the air-discharge slider 200 to move in a direction of compressing the slider elastic member 220) when the floating member 400 floats up. The front end of the exhaust slider 200 is designed with a trigger 240, and during the backward movement of the exhaust slider 200, the trigger 240 slides to the arm 132B of the lever 131, the arm 132B is pressed down, and the exhaust valve 110 is opened. Conversely, when the upper cover 102 rotates relative to the pot body 20 in a direction close to the screwing position, the floating member 400 floats downwards along the guiding inclined surface 441, when the upper cover 102 rotates to the screwing position, the push rod 420 slides down from the boss structure of the outer shell 22, the push rod 420 resets, the exhaust slider 200 resets under the driving of the slider elastic member 220, so that the trigger part 240 leaves the force arm 132B, the lever 131 resets, and the exhaust valve 110 closes.
