It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1, 3 and 4, the sealing structure of the present embodiment includes: an annular connection 10, a first annular lip 20, and a plurality of first raised structures 30. Wherein the annular connection 10 has a first annular surface 11 and a second annular surface 12; a first annular lip 20 is provided on the first annular surface 11 of the annular connection 10 and extends away from the second annular surface 12; the plurality of first protruding structures 30 are arranged on the first annular surface 11 at intervals along the circumferential direction of the annular connecting portion 10, and each first protruding structure 30 is arranged along the inner and outer directions of the annular connecting portion 10, wherein the ratio of the thickness of the annular connecting portion 10 to the thickness of the first protruding structure 30 is between 1 and 35.

By applying the technical solution of the present embodiment, the sealing structure is used for sealing the gap between the inner pot 62 and the cover 70. Specifically, the annular connecting portion 10 is sandwiched between the flange 621 of the inner pot 62 and the cover 70, the first annular surface 11 is in contact fit with the upper surface of the flange 621, and the second annular surface 12 is in contact fit with the lower surface of the cover. The first annular lip 20 extends into the mouth of the inner pan 62 and engages the side wall of the inner pan 62 to seal the gap between the inner pan 62 and the cover 70. By using the sealing structure of the embodiment, after the cover body 70 is covered, the gap between two adjacent first protrusion structures 30 can form a gas flow channel, so that the contact area between the annular connecting part 10 and the inner pot 62 is reduced, on one hand, the adsorption force of the sealing structure on the inner pot is reduced, and the probability of pot suction is effectively reduced. On the other hand, the friction force between the annular connecting part 10 and the flange 621 is reduced, so that the cover body 70 can be more smoothly opened and locked in a rotating manner, and the use experience of a user is improved.

In addition, the setting range of the thickness of the first protruding structure 30 may be flexible, but the too large thickness of the first protruding structure 30 may occupy a larger space in the height direction of the cooking appliance, so in this embodiment, the maximum thickness of the first protruding structure 30 may be the same as the thickness of the annular connecting portion 10, and in the case that the thickness of the first protruding structure 30 is larger, the setting density of the first protruding structure 30 may be correspondingly reduced. In addition, the thickness of the first protruding structures 30 can be set to be smaller, and the effect of forming the airflow channel can also be achieved by correspondingly increasing the density of the first protruding structures 30.

Preferably, the ratio of the thickness of the annular connection portion 10 to the thickness of the first raised structure 30 is between 1 and 20.

Specifically, when the radian between the annular connecting portion 10 and the first annular lip 20 of the sealing structure is different from the radian between the turned edge 621 and the side wall of the inner pot 62, an air chamber is easily formed between the sealing structure and the inner pot 62, and a gap between two adjacent first protruding structures 30 can form an air flow channel communicated with the air chamber, so that the adsorption force between the sealing structure and the inner pot 62 is reduced, and the probability of pot sucking phenomenon is effectively reduced.

It should be noted that, the above-mentioned "the first protrusion structure 30 is disposed along the inner and outer directions of the annular connection portion 10" means that the first end of the first protrusion structure 30 is close to the inner edge of the annular connection portion 10, and the second end of the first protrusion structure 30 is close to the outer edge of the annular connection portion 10. In this embodiment, the first protruding structures 30 may be disposed along the radial direction of the annular connecting portion 10, and the extending direction of the first protruding structures 30 may also be disposed at an included angle smaller than 30 ° with the radial direction of the annular connecting portion 10.

As shown in fig. 1, 2 and 6, in the present embodiment, the minimum interval L1 between two adjacent first projection structures 30 is between 0.1mm and 50 mm. In the above structure, when the thickness of the first protrusion structure 30 is set to be larger, the distance between two adjacent first protrusion structures 30 can be increased, and the arrangement density of the first protrusion structures 30 can be reduced, so as to reduce the production cost of the sealing structure. Accordingly, when the thickness of the first protruding structures 30 is set to be smaller, the distance between two adjacent first protruding structures 30 can be reduced to ensure that an airflow channel is formed between two adjacent first protruding structures 30, and the adsorption force between the sealing structure and the inner pan 62 is reduced. Preferably, the minimum interval L1 between two adjacent first projection structures 30 is between 10mm and 50 mm.

It should be noted that, in the present embodiment, the plurality of first protrusion structures 30 are distributed at equal intervals.

As shown in fig. 4 to 6, in the present embodiment, the sealing structure further includes a second annular lip 40, and the second annular lip 40 is provided on the second annular surface 12 of the annular connection portion 10 and extends in a direction away from the first annular surface 11. In the above configuration, the second annular lip 40 can extend toward the cover 70 and engage with the inner sidewall of the cover 70 to facilitate the sealing structure and the cover 70 to be sealingly connected. In the present embodiment, the annular connection portion 10, the first annular lip 20, and the second annular lip 40 are integrally connected and formed.

It should also be noted that in the case where the sealing structure of the present application includes only the annular connection portion 10 and the first annular lip 20, the sealing structure is sealed in the following manner: the annular connecting portion 10 is sandwiched between the turned edge 621 of the inner pot 62 and the cover 70, the first annular surface 11 is in contact fit with the upper surface of the turned edge 621, and the second annular surface 12 is in contact fit with the lower surface of the cover. The first annular lip 20 extends into the mouth of the inner pan 62 and engages the side wall of the inner pan 62 to seal the gap between the inner pan 62 and the cover 70. In the case where the sealing structure of the present application includes the annular connection portion 10, the first annular lip 20, and the second annular lip 40, the sealing structure is sealed in the following manner: the annular connecting part 10 is clamped between the turned-over edge 621 of the inner pot 62 and the cover body 70, the first annular surface 11 is in contact fit with the upper surface of the turned-over edge 621, and the second annular surface 12 is in contact fit with the lower surface of the cover body. The first annular lip 20 extends into the mouth of the inner pan 62 and engages the side wall of the inner pan 62, and the second annular lip 40 can extend toward the cover body 70 and engage the inner side wall of the cover body 70 to effect a sealing connection of the sealing structure to the cover body 70.

The sealing structure of the present embodiment needs to reduce the absorption force between the sealing structure and the inner pan 62 while achieving sealing, so that only the first annular surface 11 of the annular connecting portion 10 contacting the inner pan 62 is provided with the plurality of first protruding structures 30 to reduce the contact area between the first annular surface 11 and the turned edge 621 of the inner pan 62. However, if the plurality of first projection structures 30 are provided only on the first annular surface 11, when installing the sealing structure, an assembler needs to distinguish the installation direction of the sealing structure such that the first projection structures 30 face the inner pan 62, which reduces the installation efficiency. In order to solve this problem, as shown in fig. 4 to 6, in the present embodiment, the seal structure further includes a plurality of second projection structures 50, the plurality of second projection structures 50 being provided on the second annular surface 12 at intervals in the circumferential direction of the annular connection portion 10, each of the second projection structures 50 being provided in the radial direction of the annular connection portion 10. In the structure, the plurality of second protruding structures 50 are arranged on the second annular surface 12, and gaps between adjacent second protruding structures 50 can form a gas flow channel, so that an installer does not need to distinguish the installation direction of the sealing structure during installation, and the installation efficiency of the sealing structure is improved.

As shown in fig. 4 and 6, in the present embodiment, the ratio of the thickness of the annular connection portion 10 to the thickness of the second projection structure 50 is between 1 and 35. Similar to the first protruding structures 30, the setting range of the thickness of the second protruding structures 50 can be flexibly selected, but the excessive thickness of the second protruding structures 50 may occupy a larger space in the height direction of the cooking appliance, so in the embodiment, the maximum thickness of the second protruding structures 50 may be the same as the thickness of the annular connecting portion 10, and in the case that the thickness of the second protruding structures 50 is larger, the setting density of the second protruding structures 50 can be correspondingly reduced. In addition, the thickness of the second protruding structures 50 can be set to be smaller, and the effect of forming the airflow channel can be achieved by correspondingly increasing the density of the first protruding structures 30. Preferably, the ratio of the thickness of the annular connection portion 10 to the thickness of the second projection structure 50 is between 1 and 20.

As shown in fig. 4 and 6, in the present embodiment, the minimum interval between two adjacent second projection structures 50 is between 0.1mm and 50 mm. In the above structure, when the thickness of the second protrusion structure 50 is set to be larger, the distance between two adjacent second protrusion structures 50 can be increased, and the arrangement density of the second protrusion structures 50 can be reduced, so as to reduce the production cost of the sealing structure. Accordingly, when the thickness of the second protrusion structures 50 is set to be smaller, the distance between two adjacent second protrusion structures 50 can be reduced to ensure that an air flow channel is formed between the two adjacent second protrusion structures 50, and the adsorption force between the sealing structure and the inner pan 62 is reduced. Preferably, the minimum spacing between two adjacent first projection structures 30 is between 10mm and 50 mm.

In other embodiments, the projection portions of the plurality of first projection structures 30 and the plurality of second projection structures 50 in the horizontal plane are overlapped or spaced apart. In the above structure, the plurality of first projection structures 30 and the plurality of second projection structures 50 are asymmetrically arranged, and an effect that the mounting direction does not need to be distinguished when mounting can be achieved.

In further embodiments, the plurality of first raised structures 30 and the plurality of second raised structures 50 may also be arranged in a different height manner. Once the first and second annular lips 20 and 40 have different structures, and it is necessary to distinguish the installation direction of the sealing structure, the installation direction of the sealing structure may be distinguished by the structure difference of the plurality of first boss structures 30 and the plurality of second boss structures 50.

As shown in fig. 3 and 5, the present application also provides a cover including: an upper cover 71, a liner cover 72, and a seal structure 80, the liner cover 72 being disposed below the upper cover 71; the sealing structure 80 is sleeved on the circumferential outer side of the liner cover 72, wherein the sealing structure is the above-mentioned sealing structure. Because seal structure has the advantage that can prevent inhaling the pot and promote the smoothness nature of uncapping, consequently the lid that has it also possesses above-mentioned advantage.

As shown in fig. 3 and 5, the present application also provides a cooking appliance, and an embodiment of the cooking appliance of the present application includes a pot body 60, a lid body 70, and a sealing structure 80. Wherein, the cooker body 60 comprises a shell 61 and an inner pot 62 arranged in the shell; the cover body 70 is covered on the cooker body 60; the lid 70 is the above lid, and the sealing structure of the lid 70 abuts against the inner pot 62 of the pot body 60 to seal the gap between the lid 70 and the pot body 60. In the above structure, since the sealing structure 80 has an advantage of preventing the pot from being sucked and improving the smoothness of opening the lid, the cooking appliance having the same also has the above advantage.

In this embodiment, the cooking appliance may be an electric pressure cooker, an electric rice cooker, an electric stewpan, a cooking machine, a multifunctional pot, or the like.
