Specifically, the spool 22 can move relative to the first cavity 213, the spool 22 moves upward relative to the position of the valve port 211 to open the valve port 211, and the spool 22 moves downward relative to the position of the valve port 211 and the spool 22 abuts against the valve port 211 to close the valve port 211. The cover body 10 is covered on the ceramic pot 30, when the steam pressure in the cooking cavity 31 is larger than the self weight of the valve core 22, the steam pressure can jack the valve core 22 to move upwards relative to the valve port 211 so as to discharge high-pressure steam; when the steam pressure in the cooking cavity 31 is less than or equal to the self weight of the valve core 22, the valve core 22 will seal the valve port 211 under the action of the self weight. After the temperature in the cooking cavity 31 is reduced, negative pressure is formed in the cooking cavity 31, so that the requirement of fresh keeping is met.

As shown in fig. 3, the valve body 22 includes a weight portion 221 and a sealing portion 222 having an end surface connected to the weight portion 221, the sealing portion 222 can be attached to the partition 212 to seal the valve port 211, and at least a portion of the weight portion 221 is exposed from the first cavity 213.

Specifically, the counterweight portion 221 and the sealing portion 222 can attach the sealing portion 222 to the partition 212 by means of self weight to seal the valve port 211, and when the steam pressure at the valve port 211 is greater than the self weight of the valve core 22, the valve core 22 is jacked up to open the valve port 211, so as to partially exhaust the steam in the cooking cavity 31. On the other hand, the counterweight 221 is at least partially exposed from the first cavity 213, so that an upward force can be conveniently applied to release the pressure of the cooking cavity 31 when the negative pressure is generated in the cooking cavity 31. It is worth mentioning that, the weight portion 221 and the sealing portion 222 are made of silicone material, and the weight of the valve core 22 can be controlled by the diameter or shape of the weight portion 221, so as to adjust and control the steam pressure in the cooking cavity 31.

As shown in fig. 3, the valve core 22 includes a connecting portion 223 and a position-limiting portion 224, the position-limiting portion 224 is connected to the other end surface of the sealing portion 222 through the connecting portion 223, the connecting portion 223 passes through the valve port 211, and the maximum diameter of the position-limiting portion 224 is larger than that of the valve port 211, so as to avoid that the valve core 22 may be separated from the first cavity 213 when the steam pressure in the cooking cavity 31 is too large or the applied force is too large. It is worth mentioning that the weight portion 221 and the sealing portion 222 are made of silicone material.

Specifically, the maximum diameter dimension of the stopper portion 224 referred to herein is the maximum dimension between two position points of the arbitrary-shaped stopper portion 224, and similarly, the maximum diameter dimension of the valve port 211 referred to herein is the maximum dimension between two position points of the arbitrary-shaped valve port 211. For example, when the cross section of the stopper portion 224 or the valve port 211 is circular, the diameter thereof is the maximum diameter of the stopper portion 224; when the cross section of the stopper portion 224 or the valve port 211 is square, the length between the square diagonals of the cross section is the maximum diameter. In addition, the shapes of the position-limiting part 224 and the valve port 211 may be different (for example, the cross section of the position-limiting part 224 is square, the cross section of the valve port 211 is circular, etc.), and it is only necessary that the position-limiting part 224 cannot be easily pulled out from the valve port 211.

As shown in fig. 3, the position-limiting portion 224 further includes at least one protrusion 225, the protrusion 225 is disposed on an end surface of the position-limiting portion 224 opposite to the partition 212, and the protrusion 225 corresponds to the partition 212, so as to prevent the end surface of the position-limiting portion 224 from being attached to the valve port 211 to seal the valve port 211.

Specifically, when the pressure in the cooking chamber 31 is too high, the valve core 22 may be pushed to move upward, and the stopper portion 224 contacts the partition 212 with respect to an end surface close to the partition 212 to seal the valve port 211; therefore, the protrusion 255 is provided on one end surface of the stopper portion 224 close to the partition 212, and the stopper portion 224 is prevented from being attached to the partition 212 to seal the valve port 211. Further, the protrusion 225 may be provided in a plurality, and is spaced apart from one end surface of the stopper portion 224. It is worth mentioning that the protrusion 225 may be implemented in a shape of a hemisphere, or a bump, etc., and the shape of the protrusion 225 is not a limitation of the present invention.

As shown in fig. 4 to 7, for the electric stewpot with a pottery pot assembly provided by the present invention, the electric stewpot is taken as an example here to explain its working process in detail: when the electric stewpan works, the temperature in the cooking cavity 31 rises to generate steam; when the steam pressure in the cooking cavity 31 is smaller than the gravity of the valve core 22, the sealing part 222 of the valve core 22 seals the valve port 211, and the steam in the cooking cavity 31 will increase with the temperature until the steam pressure is larger than the self weight of the valve core 22. At this time, the steam pushes up the sealing portion 222 of the valve body 22, so that a certain steam passage is formed between the sealing portion 222 of the valve body 22 and the partition 212 of the valve seat 21, and the steam escapes from the steam passage. When the pressure in the cooker is smaller than the self weight of the valve core 22, the sealing part 222 of the valve core 22 will be attached to the partition 212 to realize sealing and prevent the steam from overflowing, thereby forming a certain pressure in the cooking cavity 31. When the pressure in the cooker is greater than the self weight of the valve core 22, the sealing part 222 of the valve core 22 will be jacked up again, and the circulation can ensure that a certain pressure exists in the cooker and also ensure that the pressure in the cooking cavity 31 is not too large, so as to jack up the cover body 10.

When the electric stewpan stops working, the temperature in the cooking cavity 31 is reduced, steam is reduced, the sealing portion 222 of the valve core 22 is attached to the partition plate 212 again, so that outside air cannot enter the cooking cavity 31, and due to the change of the temperature in the cooking cavity 31, the pressure in the cooking cavity 31 is smaller than the atmospheric pressure outside the cooking cavity 31, so that a certain negative pressure is formed in the cooking cavity 31, and the food fresh-keeping effect is achieved.

When negative pressure is formed in the cooking cavity 31, if the lid 10 needs to be removed from the pottery pot 30, the weight portion 221 of the valve core 22 is lifted up by hand or shifted to one side, so that the negative pressure in the cooking cavity 31 can be removed, and the lid 10 can be removed.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be taken as limiting the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
