Example two

Referring to fig. 6 and 7, the present embodiment is different from the first embodiment in that: the pot edge of the pot container 120 is provided with a pot container tooth 121, the pot cover 200 (steel cover 220) is buckled with the pot container 120, the sealing ring 300 is matched on the annular step 221, and after the pot cover 200 is screwed in place, the pot edge of the pot container 120 and the annular step 221 of the steel cover 220 form sealing through the sealing ring 300. Because the pot container 120 can be accommodated in the outer pot 110 in a pick-and-place manner, the pot cover 200 is buckled with the pot container 120, the pick-and-place of the pot container 120 is not limited by the outer pot 110, and the design has the advantages that: 1. after the pressure cooking appliance finishes cooking, the pot cover 200 and the pot container 120 can be taken out of the pot body together for cooling, for example, the pot container 120 is taken out and naturally cooled or directly put into cold water for cooling and depressurization, compared with the existing exhaust and depressurization mode, the cooling and depressurization speed is greatly improved, the waiting time for opening the cover is reduced, and the purpose of quickly opening the cover is achieved; 2. the pot container 120 can be directly placed on a dining table to be used as tableware after being taken out, so that the time for holding the tableware of food and taking the food out of the pot container is saved, and the fast-paced life requirements of a user are met, therefore, the pressure cooking appliance can be matched with two pot containers, when one pot container is used as the tableware, the other pot container is placed in the pot body to be used for cooking, the cooking efficiency is improved, and the time of the user is saved; 3. only one layer of annular step 221 needs to be arranged on the steel cover 220, so that the structure of the steel cover 220 is simplified, the height of the steel cover 220 is reduced, and the material and process cost of the steel cover 220 are saved; after the cover is closed, the ring body part of the sealing ring 300 is clamped between the annular step 221 and the pot edge of the pot container 120, the cover teeth 223 are buckled with the pot container pot teeth 121 at the pot edge of the pot container 120, when the steel cover 220 is designed, only the size relation between the annular step 221 and the cover teeth 223 needs to be considered, the manufacturing process requirement is reduced, and the consistency of the sealing performance and the pressure relief performance of the steel cover 220 can be ensured.

In this embodiment, two first limiting protrusions are circumferentially arranged on the bottom surface of at least one pot container tooth 121 at intervals, and a second limiting protrusion is arranged on the inner side of at least one tooth, so that the pot cover 200 is locked after the pot cover is closed and pressed, and the specific implementation manner can refer to embodiment one. Due to the limitation of the two first limiting bulges to the second limiting bulges, when the pot cover 200 and the pot container 120 are taken out from the pot body together, relative rotation cannot occur between the pot cover 200 and the pot container 120, and the pot container 120 is safer to move and take.

It is worth mentioning that: because the ring body part of the sealing ring 300 of the embodiment is clamped between the annular step 221 and the pot rim of the pot liner 120, in the process of opening and closing the cover, the ring body of the sealing ring 300 is separated between the pot liner pot teeth 121 and the annular step 221, the pot liner pot teeth 121 cannot contact the annular step 221, and a gap allowing at least one first limiting protrusion to pass through is arranged between the cover teeth 223 and the annular step 221, which can be understood as: the gap is formed between the upper end surface of the second limiting bulge and the lower surface of the ring body of the sealing ring 300, and the pot container and the pot teeth 121 can pass through the gap between the upper end surface of the second limiting bulge and the lower surface of the ring body of the sealing ring 300 in the cover opening and closing process.

EXAMPLE III

The difference between the present embodiment and the first embodiment is: in the embodiment, the protruding height of the left first limiting protrusion 400 relative to the top surface of the pot tooth is H1, and the protruding height of the right first limiting protrusion 500 relative to the top surface of the pot tooth is H2, so that H1 is not less than H2. A gap is formed between the top surface of the second limiting protrusion 600 and the annular step 221, the width of the gap is H, when H1 is H2, H is not more than H1, H is not more than H2, and when H1 is more than H2, H1 is not more than H2, so that the cooker cover can be locked after the cooker cover is closed and pressed. The limitation of the direction of opening and closing the pot cover can be realized by other means, such as: set up the spacing groove on the pot body, cover on the pot cover and set up spacing lug, close the pot body back when the pot cover lid, spacing lug gets into the spacing inslot and is located one side of spacing groove, and the pot cover can only make lid tooth and outer pot tooth lock to a direction rotation, and feedback user touches when spacing lug moves the opposite side of spacing groove and feels, and the suggestion closes soon and targets in place, and it is also so to uncap.
