Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking utensils, in particular to a pot cover and a pot. BACKGROUND

[0002] In daily life, pressure cookers gradually adopt double-layer pot covers, which can improve the sealing performance of the pressure cookers, thereby accelerating the cooking speed and improving the cooking efficiency. The double-layer pot cover usually includes an inner cover and an outer cover fixedly connected, a sealing ring and the like. When the double-layer pot cover is covered on the pot body of the pressure cooker and the pot cover is locked or unlocked with the pot body, the two-layer pot cover needs to be rotated, so that the user is very laborious when operating. SUMMARY

[0003] The pot cover provided by the embodiments of the present application includes a first cover body, a second cover body and a connecting piece. The connecting piece extends along the height direction of the pot cover. The first cover body and the second cover body are arranged along the height direction of the pot cover and are connected through the connecting piece. At least the first cover body and the second cover body enclose a containing cavity. The second cover body is used to cover the opening of the pot body. The connecting piece is fixedly connected or limitingly connected with the second cover body. The connecting piece is rotationally connected with the first cover body, so that the first cover body can rotate relative to the second cover body.

[0004] In the embodiments of the present application, the connecting piece is rotationally connected with the first cover body and is fixedly connected or limitingly connected with the second cover body, so that when the user rotates the pot cover, the first cover body can rotate independently relative to the second cover body. When the pot cover is covered on the pot body, the second cover body can cooperate with the pot body. During the process of rotating the pot cover to lock or unlock the pot cover with the pot body, the first cover body can rotate relative to the second cover body, thereby realizing the locking or unlocking of the pot cover with the pot body. During the process, the user only needs to provide an external force to drive the first cover body to rotate, so that the process of rotating the pot cover to lock or unlock the pot cover with the pot body is less laborious. At the same time, when the pot cover is mistakenly touched under the action of the external force to cause the first cover body to rotate, since the first cover body and the second cover body can rotate relative to each other, the first cover body will not drive the second cover body to rotate during the rotation of the first cover body, so that the second cover body remains cooperating with the pot body, so that the sealing environment in the pot body is maintained. In addition, the first cover body rotates relative to the second cover body around the connecting piece, so that the connecting piece not only serves to connect the first cover body and the second cover body, but also serves as the rotating shaft of the first cover body, thereby eliminating the need to additionally provide a rotating shaft for the first cover body, and simplifying the structure of the pot cover.

[0005] In a possible implementation, the lid further comprises a matching member sleeved outside the connecting member, and the matching member is fixedly connected or limitingly connected with the first cover body. The matching member can rotate relative to the connecting member, so that the first cover body is rotatably connected with the connecting member through the matching member.

[0006] In the embodiments of the present application, the connecting member is indirectly connected with the first cover body through the matching member. The matching member is fixedly connected or limitingly connected with the first cover body, and the matching member is rotatably connected with the connecting member (which is relatively stationary with the second cover body), so that the first cover body can rotate relative to the second cover body. Specifically, when the user rotates the first cover body (for example, through the first handle), the first cover body can drive the matching member to rotate. Since the matching member is sleeved outside the connecting member and is rotatably connected with the connecting member, the first cover body can rotate relative to the connecting member through the matching member, without driving the connecting member to rotate, and further without driving the second cover body to rotate, so as to realize the rotation of the first cover body relative to the second cover body. Meanwhile, when the first cover body and the connecting member rotate relative to each other through the matching member, since the matching member sleeved outside the connecting member has a large matching area with the connecting member, the reliability and stability of the rotation of the matching member relative to the connecting member can be improved, and further the reliability and stability of the rotation of the first cover body relative to the second cover body can be improved.

[0007] In a possible implementation, the matching member is a sleeve or a bearing.

[0008] In the embodiments of the present application, when the matching member is a sleeve, the inner wall of the sleeve and the outer wall of the connecting member have a gap therebetween, so that the two can rotate relative to each other and reduce the wear during the relative rotation. When the matching member is a bearing, the bearing not only enables the matching member to rotate relative to the connecting member, but also supports the relative rotation of the two and reduces the wear during the relative rotation, and improves the smoothness of the rotation of the first cover body.

[0009] In a possible implementation, along the height direction of the lid, one end of the matching member is located outside the accommodating cavity, and the end of the matching member located outside the accommodating cavity has an opening, and the connecting member extends outside the accommodating cavity through the opening; the lid further comprises a first fixing member fixedly connected or limitingly connected with the part of the connecting member extending outside the accommodating cavity, and the first fixing member abuts against the top wall of the matching member.

[0010] In the embodiments of the present application, the connecting piece can extend to the outside of the accommodating cavity through the opening of the fitting piece, so that the first fixing piece is fixedly connected or limitingly connected with at least part of the connecting piece extending to the outside of the accommodating cavity, which can reduce the possibility of mutual separation of the two in the height direction of the pot cover, and improve the reliability and stability of the connection between the first fixing piece and the connecting piece. In addition, the first fixing piece can abut against the top wall of the fitting piece, which can limit the downward movement of the connecting piece in the height direction of the pot cover, thereby reducing the possibility of mutual separation between the connecting piece and the fitting piece, and improving the reliability and stability of the fitting piece when rotating relative to the connecting piece. At the same time, the abutment of the first fixing piece and the top wall of the fitting piece can also reduce the possibility of mutual separation of the first cover body and the connecting piece in the height direction of the pot cover, and improve the stability of the first cover body when rotating relative to the second cover body.

[0011] In a possible implementation, the fitting piece is connected with a first support part and a second support part distributed in the height direction of the pot cover; the first support part is located in the accommodating cavity, and the first support part extends radially outward relative to the fitting piece; the second support part is located outside the accommodating cavity; the fitting piece extends to the outside of the accommodating cavity through the first cover body; and the second support part is connected with the part of the fitting piece extending to the outside of the accommodating cavity. In the height direction of the pot cover, the first support part and the second support part abut against the two end faces of the first cover body, respectively.

[0012] In the embodiments of the present application, in the height direction of the pot cover, the first support part and the second support part abut against the upper and lower end faces of the first cover body, respectively, thereby supporting the first cover body and improving the reliability of the first cover body. When the pot cover is closed on the pot body of the pressure cooker, the risk of deformation of the first cover body supported by the first support part and the second support part in the height direction of the pot cover under high pressure is relatively low, thereby improving the service life of the pot cover.

[0013] The first support part can extend radially outward relative to the fitting piece, so that the first support part can abut against the lower end face of the first cover body, and the first support part can be integrally formed with the fitting piece, thereby improving the structural stability between the two. The second support part is located outside the accommodating cavity, and the fitting piece extends to the outside of the accommodating cavity through the first cover body, thereby facilitating connection with the second support part. Specifically, at least part of the fitting piece extending to the outside of the accommodating cavity has external threads, and the second support part has internal threads, so that the second support part is screw-connected with at least part of the fitting piece extending to the outside of the accommodating cavity. The screw connection has the characteristic of high connection reliability, which can reduce the risk of mutual separation between the second support part and the fitting piece in the height direction of the pot cover, and improve the reliability of the connection between the fitting piece and the second support part.

[0014] In a possible implementation, the connecting piece is connected with a first limiting part and a second limiting part distributed along the height direction of the pot cover, the first limiting part is located in the accommodating cavity, the second limiting part is located outside the accommodating cavity, the connecting piece extends to the outside of the accommodating cavity through the second cover body, so that the second cover body and the connecting piece are limited and connected by the first limiting part and the second limiting part.

[0015] In the embodiments of the present application, the first limiting part and the second cover body are limited and connected along the height direction of the pot cover, the second limiting part and the second cover body are limited and connected, and the first limiting part and the second limiting part are located on both sides of the second cover body, so that the first limiting part and the second limiting part can limit the movement of the second cover body along the height direction of the pot cover. At the same time, along the height direction of the pot cover, the first limiting part and the second limiting part are respectively used for abutting against two end faces of the second cover body, so as to limit the upward movement of the second cover body along the height direction of the pot cover by the first limiting part, and limit the downward movement of the second cover body along the height direction of the pot cover by the second limiting part. At the same time, the first limiting part and the second limiting part can support the second cover body along the height direction of the pot cover, reduce the possibility of deformation of the second cover body inward or outward along the height direction of the pot cover, and improve the structural stability and service life of the second cover body. In addition, the second limiting part is located outside the accommodating cavity, and at least part of the connecting piece can extend to the outside of the accommodating cavity through the second cover body, so as to facilitate the connection between the second limiting part and the connecting piece and improve the connection stability therebetween.

[0016] In a possible implementation, the first limiting part extends radially outward relative to the connecting piece, and along the height direction of the pot cover, the first limiting part is used for abutting against the second cover body; the second limiting part is threadedly connected with the part of the connecting piece extending out of the accommodating cavity.

[0017] In the embodiment, the first limiting part is located in the accommodating cavity, and protrudes radially outward relative to the connecting piece. The first limiting part is used to abut against the second cover body, thereby limiting upward movement of the second cover body along the height direction of the pot cover, and increasing the contact area between the first limiting part and the second cover body, thereby improving the stability and reliability of the connection therebetween. Meanwhile, the first limiting part can abut against the second cover body, thereby improving the supporting effect of the first limiting part on the second cover body along the height direction of the pot cover, to reduce the possibility of inward deformation of the second cover body. On the other hand, the second limiting part can be threadedly connected with the part of the connecting piece extending out of the accommodating cavity. At least part of the connecting piece extending out of the accommodating cavity has external threads, and the second limiting part has internal threads, so that the second limiting part can be threadedly connected with the at least part of the connecting piece extending out of the accommodating cavity. The second limiting part can be a nut. In the embodiment, the threaded connection has the characteristic of high connection reliability, can reduce the risk of mutual disconnection of the second limiting part and the connecting piece along the height direction of the pot cover, improve the reliability of the connection between the connecting piece and the second limiting part, and the threaded connection can also facilitate connection and disconnection of the second limiting part and the connecting piece, thereby facilitating disassembly of the pot cover 1 for cleaning of the accommodating cavity.

[0018] In a possible implementation, along the height direction of the pot cover, the first limiting part is located between the connecting piece and the second cover body, and along the height direction of the pot cover, the connecting piece, the first limiting part and the second limiting part can move toward the connecting piece under the driving of the second cover body.

[0019] In the embodiment, during the process of covering the pot cover on the pot body, the pot body provides an upward force on the pot cover along the height direction of the pot cover, so that the second cover body moves in the direction toward the first cover body, that is, the second cover body and the connecting piece have a space for upward movement. By upward movement of the second cover body, the force of the pot body on the pot cover can be buffered, so that the process of covering the pot cover on the pot body is more stable, and the user experience is improved. Meanwhile, when the second cover body moves upward, the connecting piece, the first limiting part and the second limiting part connected therewith can move upward under the driving of the second cover body. When the first limiting part abuts against the lower end surface of the connecting piece, the second cover body, the connecting piece, the first limiting part and the second limiting part are limited to continue upward movement by the connecting piece, so that the movement of the second cover body, the connecting piece, the first limiting part and the second limiting part is controllable.

[0020] In a possible implementation, the second cover body has a first through hole, the pot cover includes a first sealing piece located in the accommodating cavity, the first sealing piece is sleeved on the connecting piece, and the first sealing piece can move along the height direction of the pot cover relative to the first cover body to open or block the first through hole.

[0021] In the embodiments of the present application, when the pot cover is closed on the pot body, the second cover body of the pot cover is closed on the opening of the pot body. During the cooking of the user, when the pot is in the initial heating stage, the first sealing member blocks the first through hole, so that the inner cavity of the pot body is in a sealed state, facilitating rapid cooking of food. When the pot is continuously heated to increase the pressure in the inner cavity of the pot body to a critical value, the steam can act on the first sealing member, so that the first sealing member can move away from the second cover body in the height direction of the pot cover under the action of the steam, so that the first sealing member opens the first through hole, so that the accommodation cavity can be in communication with the inner cavity of the pot body through the first through hole, and the steam in the pot body can enter the accommodation cavity through the first through hole and be discharged from the exhaust port of the pot cover, thereby preventing the safety hazard caused by excessive pressure in the pot body and improving the safety of the user during cooking.

[0022] In a possible implementation, the pot cover further comprises an elastic member located in the accommodation cavity, the elastic member is sleeved on the connecting member, and one end of the elastic member is directly or indirectly connected with the first cover body and the other end of the elastic member is directly or indirectly connected with the first sealing member in the height direction of the pot cover.

[0023] In the embodiments of the present application, when the first sealing member blocks the first through hole of the second cover body, the elastic member can be in a free state, that is, at this time the elastic member has no elastic force on the first cover body and the first sealing member, when the first sealing member blocks the first through hole, the elastic member can also be in a compressed state, and the elastic member can directly or indirectly provide a supporting force to the first cover body in the height direction of the pot cover, so as to limit the deformation and movement of the first cover body downward in the height direction of the pot cover, or the elastic member can provide a supporting force to the first supporting part, so as to make the connection between the first supporting part and the first cover body more closely while limiting the movement of the first cover body downward in the height direction of the pot cover, thereby improving the supporting performance of the first supporting part on the first cover body. In addition, the elastic member can provide a pressure to the first sealing member in the height direction of the pot cover, so as to make the connection between the first sealing member and the second cover body more closely, thereby making the sealing effect of the first sealing member on the first through hole better, and further accelerating the cooking progress.

[0024] In a possible implementation, the pot cover further comprises a second fixing member and a second sealing member, the second sealing member is used to contact the pot body and is sleeved on the outer periphery of the second cover body, the second sealing member has a mounting groove, the second fixing member comprises a first connecting part and a second connecting part, the first connecting part is embedded in the mounting groove and is clamped with the mounting groove, and the second connecting part is fixedly connected with the second cover body.

[0025] In the embodiment of the present application, the second sealing member is sleeved on the outer periphery of the second cover body. During the process of covering the pot cover on the pot body, the second cover body continuously approaches the pot body and extrudes the second sealing member, so that the second sealing member can be elastically deformed, thereby improving the sealing property between the second cover body and the pot body, and further improving the sealing effect between the pot cover and the pot body. Moreover, the second sealing member is installed on the second cover body through the second fixing member, and the second fixing member can reduce the possibility of mutual separation between the second sealing member and the second cover body, and improve the stability and reliability of the connection between the second sealing member and the second cover body.

[0026] In a possible implementation, the first sealing member is a rigid structure.

[0027] In the embodiment of the present application, when the first sealing member is a rigid structure, the strength and rigidity of the first sealing member are both high, and the first sealing member is not easy to be damaged. In the cooking process, the reliability of opening the first through hole is improved, so that the accommodation cavity is communicated with the inner cavity of the pot body, thereby improving the possibility of pressure relief, and the reliability of plugging the first through hole is also improved, thereby facilitating the realization of high-pressure environment in the pot body to improve the cooking efficiency. In addition, the service life of the first sealing member with a rigid structure is long, thereby improving the service life of the pot cover.

[0028] In a possible implementation, the first cover body includes a first body and an extension part extending along the height direction of the pot cover with respect to the first body. Along the radial direction of the pot cover, the extension part is located outside the second cover body and surrounds the second sealing member and the second fixing member.

[0029] In the embodiment of the present application, after the pot cover is covered on the pot body, the extension part of the first cover body can surround the second cover body, the second fixing member, the second sealing member and the opening of the pot body, thereby protecting the second sealing member and the connecting position between the pot body and the pot cover through the extension part, and facilitating the locking of the first cover body and the pot body through the extension part, and improving the stability and reliability of the connection between the pot cover and the pot body.

[0030] The embodiment of the present application also provides a pot, which includes a pot body and a pot cover. The pot cover is the pot cover described above. The pot cover can be covered on the opening of the pot body.

[0031] When the pot cover is closed at the opening of the pot body, the pot cover and the pot body are tightly connected through the second sealing member. At this time, the pot cover can rotate along the circumference of the pot in the first direction to achieve the locking between the pot cover and the pot body. Specifically, the locking between the pot cover and the pot body can be achieved through the connection mode of clamping. That is, when the pot cover is locked with the pot body, the protruding part on the pot cover cooperates with the protruding part on the pot body, reduces the risk of mutual separation of the pot cover and the pot body, and improves the stability and reliability of the connection between the two. When the locking between the pot cover and the pot body needs to be released, the pot cover can be rotated in the second direction opposite to the first direction, so that the protruding part on the pot cover is misaligned with the protruding part on the pot body and cooperates with the recessed part on the pot body. At this time, the locking between the pot cover and the pot body is released, and the user can separate the pot cover and the pot body in the height direction of the pot through the first handle connected with the pot cover and the second handle connected with the pot body. Therefore, in the embodiment, since the first cover body and the second cover body of the pot cover can rotate relative to each other, the pot with the pot cover can facilitate the locking or release of the pot cover and the pot body, thereby reducing the difficulty of operating the pot and improving the user experience.

[0032] In a possible implementation, the friction coefficient between the second cover body and the pot body is greater than the friction coefficient between the second cover body and the first cover body. In the embodiment, when the pot cover is closed at the opening of the pot body, the friction between the second cover body and the pot body is greater than the friction between the second cover body and the first cover body when the user applies an external force to drive the rotation of the pot cover. When the external force applied by the user is greater than the friction between the second cover body and the first cover body and less than the friction between the second cover body and the pot body, the first cover body rotates relative to the second cover body under the action of the external force to achieve the locking or release of the pot cover and the pot body. Compared with the prior art in which the user needs to apply an external force to drive the rotation of the second cover body and the first cover body, the pot cover of the present application only needs to provide an external force to drive the rotation of the first cover body, thereby facilitating the locking or release of the pot cover and the pot body, and saving labor during the locking or release. At the same time, the greater friction between the second cover body and the pot body can also reduce the risk of the second cover body rotating relative to the pot body due to accidental touch of the pot cover under the action of the external force, so as to keep the cooperation between the second cover body and the pot body and maintain the sealed environment in the pot body.

[0033] In a possible implementation, the pot cover further comprises a second sealing member in contact with the pot body, the second sealing member is sleeved on the outer periphery of the second cover body, and the second sealing member is an elastic member. The first cover body directly contacts the second cover body, or there is a gap between the first cover body and the second cover body.

[0034] In the embodiments of the present application, the second cover body and the pot body are in contact through the second sealing member, the friction coefficient between the second sealing member made of elastic material and the pot body is relatively large, meanwhile, the friction coefficient between the first cover body and the second cover body which are in direct contact or have a gap therebetween is relatively small, so that the friction coefficient between the second cover body and the pot body is larger than the friction coefficient between the second cover body and the first cover body through simple structure.

[0035] It should be understood that the general description above and the following detailed description are only exemplary and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0072] The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate embodiments consistent with the present application and, together with the description, further serve to explain the principles of the application. DETAILED DESCRIPTION

[0073] For better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0074] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0075] The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the embodiments of the present application and the accompanying claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0076] It should be understood that the term "and / or" as used herein merely describes association between associated objects, and it is possible that three relationships exist, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0077] It should be noted that the terms "upper", "lower", "left", "right" and the like described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can be directly connected to another element "on" or "under", or indirectly connected to another element "on" or "under" through an intermediate element.

[0078] The embodiments of the present application provide a pot cover, such as Figures 1-2 As shown, the pot cover 1 comprises a first cover body 11, a second cover body 12 and a connecting piece 14. The first cover body 11 and the second cover body 12 are arranged along the height direction of the pot cover 1, at least the first cover body 11 and the second cover body 12 enclose a containing cavity 13, and the second cover body 12 is used to cover the opening of the pot body 3. The air in the containing cavity 13 can slow down the loss of heat inside the pot body 3 after cooking, thereby improving the heat preservation effect. The connecting piece 14 extends along the height direction of the pot cover 1 and connects the first cover body 11 and the second cover body 12, wherein the connecting piece 14 is fixedly connected or limitingly connected with the second cover body 12, and the connecting piece 14 is rotatably connected with the first cover body 11, so that the first cover body 11 can rotate relative to the second cover body 12.

[0079] In the prior art, the first lid 11 and the second lid 12 are fixedly connected. When the user rotates the pot lid 1, the first lid 11 and the second lid 12 rotate synchronously, making it difficult for the user to lock or unlock the pot lid 1 and the pot body 3. In this application, the connector 14 is rotatably connected to the first lid 11 and fixedly or limitingly connected to the second lid 12, allowing the first lid 11 to rotate independently relative to the second lid 12 when the user rotates the pot lid 1. When the lid 1 is placed on the pot body 3, the second lid 12 can cooperate with the pot body 3. During the process of locking or unlocking the lid 1 with the pot body 3 by rotating the lid 1, the first lid 11 can rotate relative to the second lid 12, thereby locking or unlocking the lid 1 with the pot body 3. In this process, the user only needs to provide external force to drive the first lid 11 to rotate, making the process of locking or unlocking the lid 1 with the pot body 3 less strenuous. Simultaneously, when the lid 1 is accidentally touched by external force, causing the first lid 11 to rotate, since the first lid 11 and the second lid 12 can rotate relative to each other, the rotation of the first lid 11 will not cause the second lid 12 to rotate, thus maintaining the cooperation between the second lid 12 and the pot body 3 and maintaining a sealed environment inside the pot body 3.

[0080] In addition, the first cover 11 rotates relative to the second cover 12 around the connector 14. Therefore, the connector 14 can not only connect the first cover 11 and the second cover 12, but also serve as the pivot of the first cover 11, thus eliminating the need to set a separate pivot for the first cover 11 and simplifying the structure of the pot lid 1.

[0081] Among them, such as Figure 1 As shown, the lid 1 is connected to a first handle 4, and the pot body 3 is connected to a second handle 5. When the lid 1 is placed on the pot body 3, the second lid 12 is connected to the pot body 3. The user can drive the first handle 4 to rotate around the outer circumference of the pot, thereby causing the first lid 11 to rotate around the connector 14. The rotation of the first lid 11 is smooth and stable, facilitating the locking or unlocking of the lid 1 and the pot body 3. When the lid 1 and the pot body 3 are locked, the first handle 4 and the second handle 5 are locked together. When the lid 1 and the pot body 3 are unlocked, the first handle 4 and the second handle 5 are unlocked.

[0082] Specifically, such as Figures 2-4 As shown, the pot lid 1 also includes a fitting part 15 sleeved on the outside of the connector 14, and the fitting part 15 is fixedly connected or limited to the first lid body 11. The fitting part 15 can rotate relative to the connector 14 so that the first lid body 11 is rotatably connected to the connector 14 through the fitting part 15.

[0083] In the embodiment, the connecting piece 14 is indirectly connected with the first cover body 11 through the matching piece 15. The matching piece 15 is fixedly connected or positionally connected with the first cover body 11, and the matching piece 15 is rotationally connected with the connecting piece 14 (stationary relative to the second cover body 12), so that the first cover body 11 can rotate relative to the second cover body 12.

[0084] Specifically, when the user rotates the first cover body 11 (for example, through the first handle 4), the first cover body 11 can drive the matching piece 15 to rotate. Since the matching piece 15 is sleeved on the outside of the connecting piece 14 and rotationally connected with the connecting piece 14, the first cover body 11 can rotate relative to the connecting piece 14 through the matching piece 15, without driving the connecting piece 14 to rotate, and further without driving the second cover body 12 to rotate, so as to realize the rotation of the first cover body 11 relative to the second cover body 12. Meanwhile, when the first cover body 11 and the connecting piece 14 relatively rotate through the matching piece, since the matching area between the matching piece 15 and the connecting piece 14 is large, the reliability and stability of the rotation of the matching piece 15 relative to the connecting piece 14 can be improved, and further the reliability and stability of the rotation of the first cover body 11 relative to the second cover body 12 can be improved.

[0085] In the embodiment, the first cover body 11 is provided with a mounting hole for mounting the matching piece 15. At least part of the matching piece 15 can pass through the mounting hole, and the matching piece 15 and the first cover body 11 can be fixedly connected through welding, riveting or the like. For example, the matching piece 15 can be fixedly connected with the side wall of the mounting hole of the first cover body 11. Alternatively, the matching piece 15 can be integrally formed with the first cover body 11.

[0086] In a specific embodiment, the matching piece 15 is a sleeve or a bearing. When the matching piece 15 is a sleeve, the inner wall of the sleeve and the outer wall of the connecting piece 14 have a gap therebetween, so that the two can relatively rotate and reduce the abrasion during the relative rotation.

[0087] When the matching piece 15 is a bearing, the bearing not only can realize the rotation of the matching piece 15 relative to the connecting piece 14, but also can support the relative rotation of the two and reduce the abrasion during the relative rotation, and improve the smoothness of the rotation of the first cover body 11.

[0088] In a specific embodiment, as shown in FIG. 1, the matching piece 15 is a sleeve. Figures 2-4As shown, the fitting piece 15 is connected with a first support part 151 and a second support part 152 distributed along the height direction of the pot cover 1. The first support part 151 is located in the accommodating cavity 13, and the first support part 151 extends radially outward relative to the fitting piece 15. The second support part 152 is located outside the accommodating cavity 13, the fitting piece 15 extends to the outside of the accommodating cavity 13 through the first cover body 11, and the second support part 152 is connected with the part of the fitting piece 15 extending out of the accommodating cavity 13. Along the height direction of the pot cover 1, the first support part 151 and the second support part 152 respectively abut against the two end faces of the first cover body 11.

[0089] In the embodiment, along the height direction of the pot cover 1, the first support part 151 and the second support part 152 respectively abut against the upper and lower end faces of the first cover body 11, thereby supporting the first cover body 11 and improving the reliability of the first cover body 11. When the pot cover 1 is covered on the pot body 3 of the pressure cooker, the first cover body 11 supported by the first support part 151 and the second support part 152 has a lower risk of deforming along the height direction of the pot cover 1 under high pressure, thereby improving the service life of the pot cover 1.

[0090] The first support part 151 can extend radially outward relative to the fitting piece 15, so that the first support part 151 can abut against the lower end face of the first cover body 11, and the first support part 151 can be integrally formed with the fitting piece 15, thereby improving the structural stability between the first support part 151 and the fitting piece 15.

[0091] The second support part 152 is located outside the accommodating cavity 13, and the fitting piece 15 extends to the outside of the accommodating cavity 13 through the first cover body 11, thereby facilitating the connection with the second support part 152. Specifically, at least part of the fitting piece 15 extending out of the accommodating cavity 13 has external threads, and the second support part 152 has internal threads, so that the second support part 152 is threadedly connected with at least part of the fitting piece 15 extending out of the accommodating cavity 13. The threaded connection has the characteristics of high connection reliability, can reduce the risk of the second support part 152 and the fitting piece 15 being separated from each other along the height direction of the pot cover 1, and improves the connection reliability between the fitting piece 15 and the second support part 152.

[0092] In other embodiments, the second support part 152 and the fitting piece 15 can also be connected by other means, such as welding, clamping, etc. In the embodiment, when the second support part 152 and the fitting piece 15 are threadedly connected, the structure is simple and easy to disassemble.

[0093] In a specific implementation manner, as Figures 2-4As shown, along the height direction of the pot cover 1, one end of the fitting piece 15 is located outside the accommodating cavity 13, and the one end of the fitting piece 15 outside the accommodating cavity 13 has an opening, and the connecting piece 14 extends to the outside of the accommodating cavity 13 through the opening; the pot cover 1 further comprises a first fixing piece 16, the first fixing piece 16 is fixedly connected or limitingly connected with the part of the connecting piece 14 extending outside the accommodating cavity 13, and the first fixing piece 16 abuts against the top wall of the fitting piece 15.

[0094] In the embodiment, the connecting piece 14 can extend to the outside of the accommodating cavity 13 through the opening of the fitting piece 15, so that the first fixing piece 16 is fixedly connected or limitingly connected with at least part of the connecting piece 14 extending outside the accommodating cavity 13, which can reduce the possibility of mutual separation of the two along the height direction of the pot cover 1, and improve the reliability and stability of the connection between the first fixing piece 16 and the connecting piece 14. The first fixing piece 16 can abut against the top wall of the fitting piece 15, which can limit the downward movement of the connecting piece 14 along the height direction of the pot cover 1, thereby reducing the possibility of mutual separation between the connecting piece 14 and the fitting piece 15, and improving the reliability and stability of the fitting piece 15 when rotating relative to the connecting piece 14. At the same time, the abutment of the first fixing piece 16 and the top wall of the fitting piece 15 can also reduce the possibility of mutual separation of the first cover body 11 and the connecting piece 14 along the height direction of the pot cover 1, and improve the stability of the first cover body 11 when rotating relative to the second cover body 12.

[0095] In a specific embodiment, as shown in Figures 2-4 、 Figures 6-8 The connecting piece 14 is connected with a first limiting part 141 and a second limiting part 142 distributed along the height direction of the pot cover 1, the first limiting part 141 is located inside the accommodating cavity 13, and the second limiting part 142 is located outside the accommodating cavity 13, the connecting piece 14 extends to the outside of the accommodating cavity 13 through the second cover body 12, so that the second cover body 12 and the connecting piece 14 are limitingly connected through the first limiting part 141 and the second limiting part 142.

[0096] In the embodiment, the first limiting part 141 is in limiting connection with the second cover body 12 in the height direction of the pot cover 1, the second limiting part 142 is in limiting connection with the second cover body 12, and the first limiting part 141 and the second limiting part 142 are located on both sides of the second cover body 12, so that the first limiting part 141 and the second limiting part 142 can limit the movement of the second cover body 12 in the height direction of the pot cover 1. At the same time, the first limiting part 141 and the second limiting part 142 are respectively used to abut against two end faces of the second cover body 12 in the height direction of the pot cover 1, so as to limit the upward movement of the second cover body 12 in the height direction of the pot cover 1 by the first limiting part 141 and limit the downward movement of the second cover body 12 in the height direction of the pot cover 1 by the second limiting part 142. At the same time, the first limiting part 141 and the second limiting part 142 can support the second cover body 12 in the height direction of the pot cover 1, reduce the possibility of deformation of the second cover body 12 inwards or outwards in the height direction of the pot cover 1, and improve the structural stability and service life of the second cover body 12. In addition, the second limiting part 142 is located outside the accommodating cavity 13, and at least part of the connecting piece 14 can extend to the outside of the accommodating cavity 13 through the second cover body 12, so as to facilitate the connection between the second limiting part 142 and the connecting piece 14 and improve the connection stability therebetween.

[0097] In a specific embodiment, as shown in Figures 2-4 、 Figures 6-8 The first limiting part 141 can extend radially outward relative to the connecting piece 14, and abut against the second cover body 12 in the height direction of the pot cover 1.

[0098] In the embodiment, as shown in Figures 2-4 The first limiting part 141 is located in the accommodating cavity 13, and protrudes radially outward relative to the connecting piece 14, and abuts against the second cover body 12, so as to limit the upward movement of the second cover body 12 in the height direction of the pot cover 1, and increase the contact area between the first limiting part 141 and the second cover body 12, so as to improve the stability and reliability of the connection therebetween. At the same time, the first limiting part 141 can abut against the second cover body 12, so as to improve the supporting effect of the first limiting part 141 on the second cover body 12 in the height direction of the pot cover 1, so as to reduce the possibility of deformation of the second cover body 12 inwards.

[0099] On the other hand, as shown in Figures 2-4 、 Figures 6-8As shown, the second limiting part 142 can be threadedly connected with the part of the connecting piece 14 extending out of the accommodating cavity 13. The part of the connecting piece 14 extending out of the accommodating cavity 13 has external threads, and the second limiting part 142 has internal threads, so that the second limiting part 142 can be threadedly connected with the part of the connecting piece 14 extending out of the accommodating cavity 13. The second limiting part 142 can be a nut. In this embodiment, the threaded connection has the characteristic of high connection reliability, can reduce the risk of the second limiting part 142 being separated from the connecting piece 14 in the height direction of the pot cover 1, improve the connection reliability between the connecting piece 14 and the second limiting part 142, and the threaded connection can also facilitate the connection and disconnection of the second limiting part 142 and the connecting piece 14, thereby facilitating the detachable connection of the pot cover 1 for cleaning the accommodating cavity 13.

[0100] The first limiting part 141 can be integrally formed with the connecting piece 14 to improve the structural stability therebetween.

[0101] In a possible implementation, the first limiting part 141 and the second limiting part 142 can be clamped with the connecting piece 14 to facilitate the fixed connection therebetween. In other embodiments, the second limiting part 142 can be fixedly connected with the second cover body 12 to reduce the possibility of the connecting piece 14 being separated from the second cover body 12 and improve the stability and reliability of the connection between the first limiting part 141, the second limiting part 142, and the second cover body 12.

[0102] Specifically, as shown, Figures 1-4 in the height direction of the pot cover 1, the first limiting part 141 is located between the cooperating piece 15 and the second cover body 12, and in the height direction of the pot cover 1, the connecting piece 14, the first limiting part 141, and the second limiting part 142 can move toward the cooperating piece 15 under the driving of the second cover body 12.

[0103] In the process of covering the pot cover 1 on the pot body 3, the pot body 3 provides an upward force on the pot cover 1 in the height direction of the pot cover 1, so that the second cover body 12 moves in the direction toward the first cover body 11, i.e., the second cover body 12 and the connecting piece 14 have a space for upward movement. By upward movement of the second cover body 12, the force of the pot body 3 on the pot cover 1 can be buffered, so that the process of covering the pot cover 1 on the pot body 3 is more stable, and the user experience is improved. At the same time, when the second cover body 12 moves upward, the connecting piece 14, the first limiting part 141, and the second limiting part 142 connected therewith can move upward, and when the first limiting part 141 abuts against the lower end surface of the cooperating piece 15, the second cover body 12, the connecting piece 14, the first limiting part 141, and the second limiting part 142 can be limited from further upward movement by the cooperating piece 15, so that the movement of the second cover body 12, the connecting piece 14, the first limiting part 141, and the second limiting part 142 is controllable.

[0104] In the above embodiments, as shown in Figure 2 and Figures 6-8 , the second cover 12 has a first through hole 121, the pot cover 1 comprises a first sealing member 17 located in the accommodating cavity 13, the first sealing member 17 is sleeved on the connecting member 14, and the first sealing member 17 is movable relative to the first cover 11 along the height direction of the pot cover 1 to open or block the first through hole 121.

[0105] In the embodiments of the present application, when the pot cover 1 is covered on the pot body 3, the second cover 12 of the pot cover 1 covers the opening of the pot body 3. During the cooking process of the user, when the pot is in the initial heating stage, the first sealing member 17 blocks the first through hole 121, so that the inner cavity of the pot body 3 is in a sealed state, facilitating rapid cooking of food. When the pot is continuously heated so that the pressure in the inner cavity of the pot body 3 increases and approaches a critical value, steam can act on the first sealing member 17, so that the first sealing member 17 can move away from the second cover 12 along the height direction of the pot cover 1 to open the first through hole 121, so that the accommodating cavity 13 can be communicated with the inner cavity of the pot body 3 through the first through hole 121, and the steam in the pot body 3 can enter the accommodating cavity 13 through the first through hole 121 and be discharged from the exhaust port of the pot cover 1, thereby preventing the safety hazard caused by excessive pressure in the pot body 3 and improving the safety of the user during cooking.

[0106] In a possible implementation, the second cover 12 has a plurality of first through holes 121, and the plurality of first through holes 121 are distributed at intervals in the circumferential direction, so as to improve the exhaust efficiency. Correspondingly, the first sealing member 17 has an annular structure, so as to block or open each first through hole 121.

[0107] In the case that the pot is continuously heated so that the inner cavity of the pot body 3 is boiled, the soup in the inner cavity of the pot body 3 can be splashed into the accommodating cavity 13 through the first through hole 121 and collected in the accommodating cavity 13, facilitating centralized cleaning after cooking and improving the user's experience. At the same time, in the height direction of the pot cover 1, the first cover 11 is located on the side of the second cover 12 away from the pot body, and when the first through hole 121 produces a large noise during exhaust in the accommodating cavity 13, the first cover 11 can block a part of the noise from being transmitted outward, so that the sound emitted by the pot during cooking is smaller, improving the user's experience during cooking.

[0108] In a specific embodiment, as shown in Figures 2-4 , Figures 6-7As shown, the pot cover 1 further comprises an elastic member 18 located in the accommodating cavity 13, the elastic member 18 is sleeved on the connecting member 14, and one end of the elastic member 18 is directly or indirectly connected with the first cover body 11 along the height direction of the pot cover 1, that is, the one end of the elastic member 18 can be directly connected (for example, abutted) with the first cover body 11, or connected (for example, abutted) with the matching member 15 and the first supporting part 151 fixedly connected with the first cover body 11, and the other end of the elastic member 18 is directly or indirectly connected with the first sealing member 17, that is, the other end of the elastic member 18 can be directly connected (for example, abutted) with the first sealing member 17, or connected (for example, abutted) with the second cover body 12 connected with the first sealing member 17. And the elastic member 18 can be elastically deformed along the height direction of the pot cover 1.

[0109] When the first sealing member 17 blocks the first through hole 121 of the second cover body 12, the elastic member 18 can be in a free state, that is, at this time the elastic member 18 has no elastic force to the first cover body 11 and the first sealing member 17, when the first sealing member 17 blocks the first through hole 121, the elastic member 18 can also be in a compressed state, and the elastic member 18 can directly or indirectly provide a supporting force to the first cover body 11 along the height direction of the pot cover 1, so as to limit the deformation and movement of the first cover body 11 along the height direction of the pot cover 1, or the elastic member 18 can provide a supporting force to the first supporting part 151, so as to make the connection between the first supporting part 151 and the first cover body 11 more closely, and improve the supporting performance of the first supporting part 151 to the first cover body 11. In addition, along the height direction of the pot cover 1, the elastic member 18 can provide a pressure to the first sealing member 17, so that the connection between the first sealing member 17 and the second cover body 12 is more closely, so that the sealing effect of the first sealing member 17 to the first through hole 121 is better, and further the cooking progress can be accelerated.

[0110] When the first sealing member 17 is subjected to an upward force along the height direction of the pot cover 1, and moves upward and disengages from the second cover body 12, the elastic member 18 is in a compressed state and exerts an elastic force on the first sealing member 17 and the first cover body 11. The elastic force of the elastic member 18 can provide resistance to the upward movement of the first sealing member 17 along the height direction of the pot cover 1, when the upward force on the first sealing member 17 along the height direction of the pot cover 1 decreases or disappears, the first sealing member 17 can move towards the second cover body 12 and re-engage with the second cover body 12 under the elastic force of the elastic member 18, so that the first sealing member 17 re-blocks the first through hole 121.

[0111] Therefore, in the embodiment, the elastic member 18 can improve the reliability of the first sealing member 17 in blocking the first through hole 121, and can drive the first sealing member 17 to re-block the first through hole 121.

[0112] More specifically, as shown in Figure 2 the elastic member 18 is sleeved on the outer side of the fitting member 15, and one end of the elastic member 18 is directly connected with the first supporting part 151 in the height direction of the pot cover 1, that is, the one end of the elastic member 18 can abut against the first supporting part 151, and the other end is directly connected with the first sealing member 17, that is, the other end of the elastic member 18 can abut against the first sealing member 17. Among them, the fitting member 15 can play a limiting role on the elastic member 18, avoiding the elastic member 18 from being disconnected with the first supporting part 151 and the first sealing member 17 in the process of elastic deformation, and improving the stability and reliability of the elastic deformation of the elastic member 18.

[0113] In a specific embodiment, the first sealing member 17 is a rigid structure. When the first sealing member 17 is a rigid structure, the strength and rigidity of the first sealing member 17 are both high, and the first sealing member 17 is not easy to be damaged, which improves the reliability of opening the first through hole 121 in the cooking process, so that the containing cavity 13 is communicated with the inner cavity of the pot body 3, thereby improving the possibility of pressure relief, and at the same time, the reliability of plugging the first through hole 121 is also improved, thereby facilitating the realization of high-pressure environment in the pot body 3 to improve the cooking efficiency. In addition, the service life of the first sealing member 17 with a rigid structure is longer, thereby improving the service life of the pot cover 1.

[0114] In another specific embodiment, the first sealing member 17 can also be an elastic body, that is, the first sealing member 17 includes a plugging part and a mounting part, the mounting part is directly or indirectly connected with the second cover body 12, and the plugging part can be elastically deformed and is used to plug or open the first through hole 121. When the first sealing member 17 is subjected to an upward force in the height direction of the pot cover 1, the plugging part of the first sealing member 17 used to plug the first through hole 121 can be elastically deformed upward in the height direction of the pot cover 1 and be raised, thereby opening the first through hole 121, so that the containing cavity 13 is communicated with the inner cavity of the pot body 3, thereby achieving the purpose of pressure relief of the pot body 3. When the external force acting on the first sealing member 17 gradually decreases to be less than the resilience of the plugging part, the plugging part is elastically deformed, so that the plugging part re-plugs the first through hole 121. Therefore, in this embodiment, the plugging or opening of the first through hole 121 can be realized by the elastic deformation of the plugging part of the first sealing member 17, without the need to additionally set the elastic member 18.

[0115] In the above embodiments, as shown in Figure 2 and Figures 5-8As shown, the pot cover 1 further comprises a second fixing member 19 and a second sealing member 110, the second sealing member 110 is used to contact with the pot body 3 and is sleeved on the outer periphery of the second cover body 12, the second sealing member 110 has a mounting groove 1101, the second fixing member 19 comprises a first connecting part 191 and a second connecting part 192, the first connecting part 191 is embedded in the mounting groove 1101 and is clamped with the mounting groove 1101, and the second connecting part 192 is fixedly connected with the second cover body 12.

[0116] In the embodiment of the present application, the second sealing member 110 is sleeved on the outer periphery of the second cover body 12, in the process of covering the pot cover 1 on the pot body 3, the second cover body 12 continuously approaches the pot body 3 and extrudes the second sealing member 110, so that the second sealing member 110 can be elastically deformed, thereby improving the sealing property between the second cover body 12 and the pot body 3, and further improving the sealing effect between the pot cover 1 and the pot body 3. Moreover, the second sealing member 110 is installed on the second cover body 12 through the second fixing member 19, the second fixing member 19 can reduce the possibility of mutual separation between the second sealing member 110 and the second cover body 12, and improve the stability and reliability of the connection between the second sealing member 110 and the second cover body 12. The second sealing member 110 can be a sealing rubber ring.

[0117] Specifically, the second fixing member 19 and the second sealing member 110 are fixedly connected in a clamped manner between the first connecting part 191 and the mounting groove 1101, thereby improving the stability and reliability of the connection between the second fixing member 19 and the second sealing member 110. Moreover, the second fixing member 19 is fixedly connected with the outer edge of the second cover body 12 through the second connecting part 192, so that the second sealing member 110 can be fixedly connected with the second cover body 12 through the second fixing member 19, thereby improving the stability and reliability of the mutual connection among the second cover body 12, the second fixing member 19 and the second sealing member 110, reducing the possibility of mutual separation between the second sealing member 110 and the second cover body 12 and the second fixing member 19 in the process of opening the cover, and thereby improving the overall quality of the pot cover 1.

[0118] In addition, the first connecting part 191 and the second connecting part 192 can be integrally formed, thereby improving the structural stability of the second fixing member 19. Moreover, the second fixing member 19 can be annular and cooperates with the second cover body 12 and the second sealing member 110, or the second fixing member 19 can be a plurality of fixing blocks and is spaced apart along the circumferential direction of the second cover body 12, thereby reducing the weight of the second cover body 12 to achieve the purpose of lightening the pot cover 1.

[0119] In a specific embodiment, as shown in Figure 2 and Figure 5As shown, the second cover body 12 includes a second body 122 and a flange 123 extending outward relative to the second body 122, and the second sealing member 110 is located on a side of the flange 123 away from the first cover body 11, and the second sealing member 110 is configured to contact the pot body 3.

[0120] In the embodiments of the present application, the second sealing member 110 is fixedly connected to the side of the flange 123 away from the first cover body 11 by the second fixing member 19, and in the process of covering the pot body 3 by the pot cover 1, the second sealing member 110 can contact the pot body 3, so that the second sealing member 110 can contact the pot body 3 in the process of installing the pot cover 1 on the pot body 3, thereby improving the sealing performance between the pot cover 1 and the pot body 3, and further improving the sealing effect of the cooking utensil in the cooking process.

[0121] In a specific embodiment, as shown in Figure 2 and Figure 5 As shown, the first cover body 11 includes a first body 111 and an extension 112 extending along the height direction of the pot cover 1 relative to the first body 111, and along the radial direction of the pot cover 1, the extension 112 is located outside the second cover body 12 and surrounds the second sealing member 110 and the second fixing member 19.

[0122] In the embodiments of the present application, after the pot cover 1 covers the pot body 3, the extension 112 of the first cover body 11 can surround the second cover body 12, the second fixing member 19, the second sealing member 110 and the opening of the pot body 3, so as to protect the second sealing member 110 and the connecting position between the pot body 3 and the pot cover 1 by the extension 112, and facilitate the locking of the first cover body 11 and the pot body 3 by the extension 112, thereby improving the stability and reliability of the connection between the pot cover 1 and the pot body 3.

[0123] In the embodiments of the present application, the radial dimension of the first body 111 is greater than the radial dimension of the second body 122, so that the first body 111 of the first cover body 11 can cover the second cover body 12, the second fixing member 19 and the second sealing member 110 along the radial direction of the pot cover 1.

[0124] In a specific embodiment, the first cover body 11 is provided with a third through hole 113, which can serve as an exhaust hole of the pot cover 1, so that the steam in the pot body 3 can flow out to the outside environment through the third through hole 113 after flowing into the accommodation cavity 13, thereby improving the exhaust efficiency of the cooking utensil.

[0125] The embodiments of the present application also provide a cooking utensil, as shown in Figure 1 The cooking utensil includes a pot body 3 and a pot cover 1. The pot cover 1 is the pot cover 1 described above, and the pot cover 1 can cover the opening of the pot body 3.

[0126] In the embodiments of the present application, when the pot cover 1 is covered on the opening of the pot body 3, the pot cover 1 and the pot body 3 are tightly connected through the second sealing element 110, at this time, the pot cover 1 can be rotated along the circumference of the pot in the first direction, so as to realize the locking between the pot cover 1 and the pot body 3, specifically, the locking between the pot cover 1 and the pot body 3 can be realized through the clamping connection mode, that is, when the pot cover 1 is locked with the pot body 3, the protruding part on the pot cover 1 cooperates with the protruding part on the pot body 3, which reduces the risk of separation of the pot cover 1 and the pot body 3, and improves the stability and reliability of the connection between the two. When the locking between the pot cover 1 and the pot body 3 needs to be released, the pot cover 1 can be rotated in the second direction opposite to the first direction, so that the protruding part on the pot cover 1 is misaligned with the protruding part on the pot body 3, and cooperates with the recessed part on the pot body 3, at this time, the locking between the pot cover 1 and the pot body 3 is released, and the user can separate the pot cover 1 and the pot body 3 in the height direction of the pot through the first handle 4 connected with the pot cover 1 and the second handle 5 connected with the pot body 3.

[0127] Therefore, in the embodiments, since the first cover body 11 and the second cover body 12 of the pot cover 1 can rotate relative to each other, the pot with the pot cover 1 can facilitate the locking or releasing of the pot cover 1 and the pot body 3, thereby reducing the difficulty of operating the pot and improving the user experience.

[0128] Specifically, the friction coefficient between the second cover body 12 and the pot body 3 is greater than the friction coefficient between the second cover body 12 and the first cover body 11.

[0129] In the embodiments of the present application, when the pot cover 1 is covered on the opening of the pot body 3, when the user applies an external force to drive the rotation of the pot cover 1, the friction between the second cover body 12 and the pot body 3 is greater than the friction between the second cover body 12 and the first cover body 11, when the external force applied by the user is greater than the friction between the second cover body 12 and the first cover body 11 and less than the friction between the second cover body 12 and the pot body 3, under the action of the external force, the first cover body 11 rotates relative to the second cover body 12 to realize the locking or releasing of the pot cover 1 and the pot body 3. Compared with the prior art in which the user needs to apply an external force to drive the rotation of the second cover body 12 and the first cover body 11, the pot cover 1 of the present application only needs to provide an external force to drive the rotation of the first cover body 11, thereby facilitating the locking or releasing of the pot cover 1 and the pot body 3, and saving labor during the locking or releasing process. At the same time, the greater friction between the second cover body 12 and the pot body 3 can also reduce the risk of the second cover body 12 rotating relative to the pot body 3 due to the misoperation of the pot cover 1 under the action of the external force, so that the second cover body 12 and the pot body 3 remain in cooperation, maintaining the sealed environment in the pot body 3.

[0130] In addition, the pot cover 1 further comprises a second sealing member 110 in contact with the pot body 3, the second sealing member 110 is sleeved on the outer periphery of the second cover body 12, the second sealing member 110 is an elastic member, and the first cover body 11 is in direct contact with the second cover body 12, or there is a gap between the first cover body 11 and the second cover body 12.

[0131] In the embodiment of the present application, the second cover body 12 is in contact with the pot body 3 through the second sealing member 110, the friction coefficient between the second sealing member 110 made of elastic material and the pot body 3 is relatively large, and at the same time, when the first cover body 11 and the second cover body 12 are in direct contact or there is a gap between the first cover body 11 and the second cover body 12, the friction coefficient between the first cover body 11 and the second cover body 12 is relatively small, so that the friction coefficient between the second cover body 12 and the pot body 3 is greater than the friction coefficient between the second cover body 12 and the first cover body 11 through a simple structure.

[0132] In addition, when the second sealing member 110 is made of elastic material, during the process that the pot cover 1 is covered on the pot body 3, the second cover body 12 continuously approaches the pot body 3, and the second sealing member 110 is extruded by the pot body 3 in the height direction of the pot cover 1, so that at least part of the second sealing member 110 can be elastically deformed to tightly fit with the pot body 3, reduce the possibility of leakage, and improve the sealing performance between the second sealing member 110 and the pot body 3.

[0133] In a possible implementation, when the pot cover 1 is covered on the pot body 3, there is a gap between the outer edge of the first cover body 11 and the outer edge of the second cover body 12 in the height direction of the pot, specifically, there is a gap of 0.5mm-1mm between the first body 111 and the flange 123, so as to avoid the contact between the first cover body 11 and the second cover body 12, thereby preventing the first cover body 11 from rotating the second cover body 12 when the first cover body 11 rotates relative to the pot body 3.

[0134] At the same time, when the pot cover 1 is locked with the pot body 3, there is a gap between the first cover body 11 and the pot body 3 in the height direction of the pot, specifically, there is a gap of 1mm-2mm between the protruding part on the first cover body 11 and the protruding part on the pot body 3, which can facilitate the reduction of wear between the two protruding parts when they are matched, thereby improving the smoothness of the pot cover 1 and the pot body 3 when they are locked or unlocked.

[0135] In addition, the pot cover 1 further comprises a second sealing member 110 in contact with the pot body 3, the second sealing member 110 is sleeved on the outer periphery of the second cover body 12, the second sealing member 110 is an elastic member, and the first cover body 11 is in direct contact with the second cover body 12, or there is a gap between the first cover body 11 and the second cover body 12.

[0136] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
