Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a pressure cooker cover and a pressure cooker. Background Art

[0002] A pressure cooker is a common cooking appliance, and its main function is to increase the heating temperature by increasing the gas pressure in the cooker, thereby increasing the heating speed. The pressure cooker is mainly composed of a pressure cooker cover and a cooker body, and the pressure cooker cover and the cooker body are connected by a clamp assembly, and the clamp assembly can move relative to the cooker body to achieve the purpose of clamping the pressure cooker cover and the cooker body at the same time or canceling the clamping. However, the existing clamp assembly needs to match the structural shape of the pressure cooker cover, resulting in a high manufacturing cost of the pressure cooker. Summary of the invention

[0003] The present application provides a pressure cooker cover and a pressure cooker, so as to improve the versatility of a clamp assembly and reduce the manufacturing cost of the pressure cooker.

[0004] In a first aspect, the present application provides a pressure cooker cover, which comprises a cover body and a clamp assembly, wherein the clamp assembly comprises:

[0005] At least two clamps, which are arranged at the edge of the cover body and can slide along the radial direction of the cover body;

[0006] At least two locking members, which are arranged on one side of the clamp close to the axis of the cover body and can slide along the radial direction of the cover body;

[0007] A flexible traction member, connecting the clamp and the locking member;

[0008] When the locking members are close to each other, the locking members can achieve locking, the locking members tighten the flexible traction members, and the flexible traction members drive the clamps to achieve clamping;

[0009] When the locking parts cancel the locking, the locking parts can move away from each other, the locking parts release the flexible traction parts, and the clamps can cancel the clamping.

[0010] The pressure cooker lid provided by the present application includes a lid body and a clamp assembly, wherein the clamp assembly includes at least two clamps, at least two locking members and a flexible traction member; the clamp is arranged at the edge of the lid body and can slide along the radial direction of the lid body to achieve clamping or cancel clamping; the locking member is arranged on one side of the clamp close to the axis of the lid body and can slide along the radial direction of the lid body to achieve locking or cancel locking; the flexible traction member connects the clamp and the locking member; when the locking members are close to each other, the locking member can achieve locking, the locking member tightens the flexible traction member, and the flexible traction member drives the clamp to achieve clamping; when the locking member cancels the locking, the locking members can move away from each other, the locking member releases the flexible traction member, and the clamp can cancel clamping under the action of external force, etc. On the one hand, the distance between the locking member and the clamp can be set according to the size of the lid body, and the clamp assembly can be applied to lids of various sizes and specifications by only changing the length of the flexible traction member; on the other hand, since the flexible traction member can be deformed freely, the clamp assembly can adapt to lids of various structural shapes. In addition, the present application uses a locking piece to keep the clamp in a clamped state, which can effectively improve the stability of the clamp in clamping and prevent the clamp from accidentally loosening due to external forces such as vibration or impact.

[0011] Optionally, the number of the locking parts is two, and the two locking parts are arranged opposite to each other along the radial direction of the cover body, and the two locking parts are locked with each other to achieve locking. The cover body and other components only provide installation and guidance functions for the locking parts, and it is only necessary to make the shape of the locking parts match the cover head and other components; the locking fit is formed between the two locking parts, and does not rely on the cover head and other components, which can improve the reliability of the locking fit of the locking parts. In addition, the user can apply external force to the two locking parts at the same time by kneading, so that the two locking parts are close to each other to achieve locking, thereby improving the convenience of operation.

[0012] Optionally, one of the locking components is a first locking component, and the other locking component is a second locking component; the first locking component is provided with a movable portion, and the second locking component is provided with a matching portion, and the movable portion moves along a direction approaching or away from the axis of the locking component; when the first locking component and the second locking component are close to each other, the movable portion and the matching portion are stacked along a direction approaching or away from the axis of the locking component, and the movable portion and the matching portion are mutually snapped to achieve locking. The matching portion is located on one side of the movable portion along its own movement direction, so that the movable portion can move in a direction approaching the matching portion to achieve snapping, and the movable portion can move in a direction away from the matching portion to cancel the snapping. The snapping fit depth of the movable portion and the matching portion is limited by the movement stroke of the movable portion, while ensuring the reliability of the snapping fit, and will not cause large stress between the movable portion and the matching portion, thereby extending the service life of the locking component.

[0013] Optionally, one end of the movable part is pivotally connected to the first locking member, and the other end extends toward the second locking member. The movable part rotates to approach or move away from the axis of the locking member to reduce the movement resistance of the movable part and increase the stability of the movement of the movable part.

[0014] Optionally, the movable part is provided with a locking protrusion, the matching part is provided with a locking groove, and the locking groove is configured as a through groove that penetrates the matching part; the pressure cooker cover further comprises an unlocking member, the unlocking member and the movable part are respectively located on two opposite sides of the matching part, and the unlocking member and the locking protrusion pass through the locking groove and abut against each other. On the one hand, the unlocking member directly abuts against and pushes the locking protrusion, so that the locking protrusion escapes from the locking groove, which can make the operation of the unlocking member more labor-saving and efficient; on the other hand, the unlocking member and the movable part abut against each other within the range of the matching part, which can not only make the external shape of the locking member more regular, but also make the overall structure of the pressure cooker cover more compact.

[0015] Optionally, the cover body is provided with a check valve, which is lifted and lowered along the axial direction of the cover body; a stopper is extended from one side of at least one of the locking members, at least a part of the stopper is located above the check valve, and the stopper is provided with a avoidance opening; when the locking member is locked, the avoidance opening is directly opposite to the check valve; when the locking member is unlocked, the avoidance opening and the check valve are staggered. When the clamp is clamped, the check valve can form a sealed state, so that high pressure can be normally generated in the pot, meeting the requirements of high-pressure cooking; when the clamp is unclamped, the check valve remains in a pressure relief state, thereby preventing high pressure from being generated in the pot when the pressure cooker lid is not fully closed, and ensuring the safety of the pressure cooker lid.

[0016] Optionally, the two locking members arranged opposite to each other are respectively provided with the stopper, and the two stoppers are arranged at intervals in a direction away from the locking members, so that the two stoppers can respectively stop at two opposite sides of the stop valve, thereby increasing the stability of the stop valve;

[0017] The side surface on which the two stop parts face each other is the first surface, and the avoidance opening is formed by the inward depression of the first surface. The two avoidance openings together surround the outer circumference of the stop valve, thereby playing a certain guiding and limiting role on the stop valve, reducing the possible shaking of the stop valve, and increasing the stability of the stop valve in lifting and lowering.

[0018] Optionally, the pressure cooker lid also includes a protective cover, which is detachably connected to the top of the cover body, and a part of the clamp is clamped between the protective cover and the cover body, so as to reliably connect the clamp to the cover body and prevent the clamp from falling off the cover body during use; the protective cover extends along the surface of the cover body in a direction close to the axis of the cover body, and a channel is formed between the protective cover and the cover body, and the flexible traction member is passed through the channel, which can not only limit and guide the flexible traction member to prevent the flexible traction member from being exposed and damaged, but also improve the appearance of the pressure cooker lid.

[0019] Optionally, the clamp assembly also includes a cover head, which is connected to the center of the cover body, and each of the locking members is slidably connected to the cover head, which can not only reduce the number of parts, but also make full use of the internal space of the cover head to improve the compactness of the overall structure.

[0020] The second aspect of the present application provides a pressure cooker, which includes a pot body and any one of the pressure cooker lids provided in the present application. When the pressure cooker lid is connected to the pot body, the clamp can clamp the pressure cooker lid and the pot body at the same time. On the one hand, the distance between the locking member and the clamp can be set according to the size of the lid body. Only by changing the length of the flexible traction member, the clamp assembly can be adapted to lid bodies of various sizes; on the other hand, since the flexible traction member can be deformed freely, the clamp assembly can adapt to lid bodies of various structural shapes. In addition, the present application uses a locking member to keep the clamp in a clamping state, which can effectively improve the stability of the clamp in clamping and prevent the clamp from accidentally loosening due to external forces such as vibration or impact.

[0060] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying 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 it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0064] like Figure 1As shown, the embodiment of the present application provides a pressure cooker, which includes a pressure cooker cover 10 and a pot body 20, and the pressure cooker cover 10 is detachably connected to the pot body 20. The pressure cooker cover 10 includes a cover body 1 and a clamp assembly. The cover body 1 forms the main structure of the pressure cooker cover 10, and the cover body 1 is used to cover the pot body 20; when the pressure cooker cover 10 is connected to the pot body 20, the clamp assembly can clamp the pressure cooker cover 10 and the pot body 20 at the same time, thereby realizing a reliable connection between the pressure cooker cover 10 and the pot body 20.

[0065] The cover 1 may be provided with a sealing ring, a pressure limiting valve and a check valve 11. The sealing ring can form a sealed state between the pressure cooker cover 10 and the cooker body 20 to prevent the gas in the cooker from leaking between the pressure cooker cover 10 and the cooker body 20. The pressure limiting valve is used to limit the maximum pressure in the cooker to ensure the safety of the pressure cooker. The check valve 11 is provided through the cover 1 and can be raised and lowered along the cover 1; when the check valve 11 rises, a sealed state is formed between the check valve 11 and the cover 1, and a high pressure can be formed in the cooker; when the check valve 11 falls, a pressure relief state is formed between the check valve 11 and the cover 1, and the pressure in the cooker is released.

[0066] like Figure 1-Figure 9 As shown, the clamp assembly includes at least two clamps 2. The clamps 2 are arranged at the edge of the cover body 1 and can slide along the radial direction of the cover body 1 to achieve clamping or cancel clamping. Specifically, the clamps 2 move in the direction close to the axis of the cover body 1 to achieve clamping. When the clamps 2 achieve clamping, the clamps 2 clamp the pressure cooker cover 10 and the pot body 20 at the same time, so that the pressure cooker cover 10 is reliably fixed to the pot body 20; the clamps 2 move in the direction away from the axis of the cover body 1 to cancel clamping. When the clamps 2 cancel clamping, the pressure cooker cover 10 can be covered on the pot body 20 or the pressure cooker cover 10 can be removed from the pot body 20.

[0067] Furthermore, the clamp assembly also includes at least two locking members 3 and a flexible traction member 4 (for example, a metal wire, etc.). The locking member 3 is arranged on one side of the clamp 2 close to the axis of the cover body 1, and the flexible traction member 4 connects the clamp 2 and the locking member 3; the locking member 3 can slide along the radial direction of the cover body 1 to achieve locking or canceling the locking. When the locking members 3 are close to each other, the locking members 3 can achieve locking, the locking members 3 tighten the flexible traction member 4, and the flexible traction member 4 drives the clamp 2 to achieve clamping; when the locking members 3 cancel the locking, the locking members 3 can move away from each other, the locking members 3 loosen the flexible traction member 4, and the clamp 2 can cancel the clamping under the action of external force.

[0068] The embodiment of the present application adopts a flexible traction member 4 to play a transmission role between the clamp 2 and the locking member 3, which can improve the versatility of the clamp assembly and reduce the manufacturing cost of the pressure cooker. Specifically, on the one hand, the distance between the locking member 3 and the clamp 2 can be set according to the size of the cover 1. Only by changing the length of the flexible traction member 4, the clamp assembly can be applied to covers 1 of various sizes; on the other hand, since the flexible traction member 4 can be deformed freely, the clamp assembly can adapt to covers 1 of various structural shapes. In addition, the embodiment of the present application adopts the locking member 3 to keep the clamp 2 in a clamped state, which can effectively improve the stability of the clamp 2 in clamping and prevent the clamp 2 from accidentally loosening due to external forces such as vibration or impact.

[0069] Specifically, the flexible traction member 4 is arranged in one-to-one correspondence with the clamp 2, that is, each clamp 2 is connected to a flexible traction member 4. The locking member 3 and the clamp 2 can be arranged in one-to-one correspondence, that is, each locking member 3 drives one clamp 2 to move; or, the number of locking members 3 can be less than the number of clamps 2, that is, each locking member 3 can drive at least two clamps 2 to move. The locking member 3 can be slidably connected to a fixed component such as the cover body 1 or the cover head 6.

[0070] like Figure 3 As shown, a first elastic member 21 (e.g., a spring, etc.) may be provided between the clamp 2 and the cover 1, and both ends of the first elastic member 21 elastically abut against the clamp 2 and the cover 1, respectively, so as to force the clamp 2 to move in a direction away from the axis of the cover 1. The user only needs to operate the locking member 3 to cancel the locking and release the flexible traction member 4, and the clamp 2 can automatically move in a direction away from the axis of the cover 1 under the action of the first elastic member 21, thereby canceling the clamping, thereby improving the convenience of using and operating the pressure cooker cover 10.

[0071] Furthermore, the clamp 2 can be provided with a first guide groove 22, and the extension direction of the first guide groove 22 is parallel to the movement direction of the clamp 2; the surface of the cover body 1 can be provided with a first guide column 12, and the first guide column 12 is inserted into the first guide groove 22 and can slide relatively along the length direction of the first guide groove 22, thereby guiding the clamp 2 and increasing the smoothness of the movement of the clamp 2.

[0072] Furthermore, the surface of the cover body 1 is provided with a first support portion 13, and the clamp 2 is provided with a second support portion 23, and the first support portion 13 and the second support portion 23 are arranged at intervals along the radial direction of the cover body 1. One of the first support portion 13 and the second support portion 23 is provided with a latch, and the other is provided with a socket; the latch and the socket extend along the radial direction of the cover body 1, and the latch and the socket form a sliding fit. It can not only guide the clamp 2 along the radial direction of the cover body 1 to increase the stability of the movement of the clamp 2, but also limit the clamp 2 along the axial direction of the cover body 1 to reduce or avoid the up and down vibration of the clamp 2. In addition, the above-mentioned first elastic member 21 can be sleeved on the latch, and the two ends of the first elastic member 21 can elastically abut against the first support portion 13 and the second support portion 23 respectively, and the latch guides and supports the first elastic member 21.

[0073] refer to Figure 4-Figure 6 In one embodiment, there are two locking members 3, and the two locking members 3 are arranged opposite to each other along the radial direction of the cover body 1, and the two locking members 3 are locked with each other to achieve locking. The cover body 1 and other components only provide installation and guidance functions for the locking members 3, and it is only necessary to make the shape of the locking members 3 match the cover head 6 and other components; the locking fit is formed between the two locking members 3, and does not rely on the cover head 6 and other components, which can improve the reliability of the locking fit of the locking members 3. In addition, the user can apply external force to the two locking members 3 at the same time by kneading, so that the two locking members 3 are close to each other to achieve locking, thereby improving the convenience of operation.

[0074] A second elastic member 34 (e.g., a spring, etc.) may be disposed between the two locking members 3. When the two locking members 3 are unlocked, under the action of the second elastic member 34, the two locking members 3 automatically move away from each other and release the flexible traction member 4, further improving the convenience of using the pressure cooker cover 10.

[0075] Furthermore, one of the locking components 3 is a first locking component 3a, and the other locking component 3 is a second locking component 3b, and the axis of the locking component 3 refers to the line connecting the first locking component 3a and the second locking component 3b. The first locking component 3a is provided with a movable portion 31, and the second locking component 3b is provided with a matching portion 32, and the movable portion 31 moves (for example, slides or rotates, etc.) in a direction close to or away from the axis of the locking component 3. When the first locking component 3a and the second locking component 3b are close to each other, the movable portion 31 and the matching portion 32 are stacked in a direction close to or away from the axis of the locking component 3, and the movable portion 31 and the matching portion 32 are locked with each other to achieve locking. That is, the matching portion 32 is located on one side of the movable portion 31 along its own movement direction, so that the movable portion 31 can move in the direction close to the matching portion 32 to achieve buckle, and the movable portion 31 can move in the direction away from the matching portion 32 to cancel the buckle, and the buckle matching depth of the movable portion 31 and the matching portion 32 is limited by the movement stroke of the movable portion 31, while ensuring the reliability of the buckle matching, it will not cause a large stress between the movable portion 31 and the matching portion 32, thereby extending the service life of the locking member 3. It can be understood that in other embodiments, the first locking member 3a can be provided with an elastic buckle, which approaches or moves away from the matching portion 32 by deforming itself, thereby achieving buckle or canceling buckle.

[0076] Furthermore, one end of the movable part 31 is pivotally connected to the first locking member 3a, and the other end extends toward the direction close to the second locking member 3b. That is, the movable part 31 rotates to approach or move away from the axis of the locking member 3 to reduce the movement resistance of the movable part 31 and increase the smoothness of the movement of the movable part 31.

[0077] Among them, the first locking component 3a is provided with a third elastic component 35 (for example, a spring, etc.), and the third elastic component 35 is arranged on the side of the movable part 31 away from the matching part 32. The third elastic component 35 elastically abuts against the movable part 31 to force the movable part 31 to move in the direction close to the matching part 32, so that when the first locking component 3a and the second locking component 3b approach each other, the movable part 31 and the matching part 32 can automatically snap into place without manually operating the movable part 31 to move, thereby improving the convenience of operation.

[0078] Specifically, one of the movable portion 31 and the matching portion 32 is provided with a locking protrusion 311, and the other is provided with a locking groove 321. The locking protrusion 311 is raised along the stacking direction of the movable portion 31 and the matching portion 32, and the locking groove 321 is recessed along the stacking direction of the movable portion 31 and the matching portion 32; when the movable portion 31 and the matching portion 32 are stacked on each other, the locking protrusion 311 is locked in the locking groove 321, so that the locking member 3 is locked. The locking groove 321 can be set as a through groove to ensure that the locking protrusion 311 can be completely locked in the locking groove 321, so as to avoid the locking groove 321 interfering with the locking protrusion 311 in the depth direction.

[0079] Furthermore, at least one side of the locking member 3 is extended with a stopper 33, and the extension direction of the stopper 33 is parallel to the movement direction of the locking member 3; at least a part of the stopper 33 is located above the check valve 11, and the stopper 33 is provided with an escape opening 331. Figure 5 ), the avoidance opening 331 is directly opposite to the check valve 11, and the check valve 11 can pass through the avoidance opening 331 and rise, that is, when the clamp 2 is clamped, the check valve 11 can form a sealed state, so that high pressure can be normally generated in the pot to meet the high-pressure cooking requirements; when the lock member 3 is unlocked (reference Figure 4 ), the avoidance opening 331 and the check valve 11 are staggered with each other, and the check valve 11 is stopped below the stop portion 33 and cannot rise. That is to say, when the clamp 2 is unclamped, the check valve 11 remains in a pressure relief state, thereby preventing high pressure from being generated in the pot when the pressure cooker cover 10 is not fully closed, thereby ensuring the safety of the pressure cooker cover 10.

[0080] In addition, when the pot is in a high-pressure state, the clamp 2 is in a clamped state, and the non-opening valve 11 rises and passes through the avoidance opening 331. At this time, the non-opening valve 11 stops at the inner wall of the avoidance opening 331, thereby limiting the locking member 3, so that the locking members 3 cannot move away from each other, and the clamp 2 cannot cancel the clamping, ensuring that the clamp 2 is reliably maintained in the clamped state under the high-pressure state, preventing the pressure cooker cover 10 from opening accidentally under the high-pressure state.

[0081] The avoidance opening 331 can be set as a closed structure, that is, there is a gap between the avoidance opening 331 and the edge of the stopper 33. The avoidance opening 331 can also be set as an open structure, that is, the avoidance opening 331 is formed by the edge of the stopper 33 being recessed inward.

[0082] In one embodiment, two locking members 3 disposed opposite to each other are respectively provided with a stopper 33, and the two stoppers 33 are spaced apart in a direction away from the locking members 3, so that the two stoppers 33 can respectively stop at opposite sides of the stop valve 11, thereby increasing the stability of the stop valve 11. The surface of the two stoppers 33 facing each other is the first surface, and the avoidance opening 331 is formed by the first surface being recessed inwardly, and the two avoidance openings 331 are together surrounding the outer periphery of the stop valve 11, thereby playing a certain guiding and limiting role on the stop valve 11, reducing the possible shaking of the stop valve 11, and increasing the stability of the lifting and lowering of the stop valve 11.

[0083] like Figure 6-Figure 9As shown, the clamp assembly also includes an unlocking member 5, which is arranged on the side of the movable part 31 facing the matching part 32 and can move in the direction close to or away from the axis of the locking member 3. For example, the unlocking member 5 can be slidably connected to a fixed part such as the cover body 1 or the cover head 6. When the movable part 31 and the matching part 32 are locked with each other, a part of the movable part 31 is exposed outside the matching part 32; the unlocking member 5 abuts against the exposed part of the movable part 31 to push the movable part 31 to move away from the matching part 32, so that the movable part 31 and the matching part 32 are unlocked, and the first locking member 3a and the second locking member 3b are unlocked. The unlocking member 5 is set in a shape that is easy to press and operate, so as to improve the convenience of user operation.

[0084] The unlocking member 5 is provided with a fourth elastic member 51 (e.g., a spring) on ​​one side of the movable portion 31, and the fourth elastic member 51 elastically abuts against the unlocking member 5 to force the unlocking member 5 to move away from the movable portion 31, so that the unlocking member 5 can be automatically reset. The unlocking member 5 and the locking member 3 are connected to the same mounting seat, for example, the unlocking member 5 and the locking member 3 are both slidably connected to the cover head 6, and the movement direction of the unlocking member 5 is perpendicular to the movement direction of the locking member 3, further improving the compactness of the overall structure.

[0085] In one embodiment, the movable portion 31 is provided with a locking protrusion 311, and the matching portion 32 is provided with a locking groove 321, and the locking groove 321 is set as a through groove that penetrates the matching portion 32; the unlocking member 5 and the movable portion 31 are respectively located on opposite sides of the matching portion 32, and the unlocking member 5 and the locking protrusion 311 pass through the locking groove 321 and abut against each other. On the one hand, the unlocking member 5 directly abuts against and pushes the locking protrusion 311, so that the locking protrusion 311 escapes from the locking groove 321, which can make the operation of the unlocking member 5 more labor-saving and efficient; on the other hand, the unlocking member 5 and the movable portion 31 abut against each other within the range of the matching portion 32, which can make the external shape of the locking member 3 more regular and the overall structure of the pressure cooker cover 10 more compact.

[0086] Furthermore, a notch 322 penetrating the matching portion 32 is provided on one side of the slot 321 to provide a clearance for the unlocking member 5, ensuring that after the movable portion 31 and the matching portion 32 are unfastened, the two locking members 3 can smoothly move away from each other, thereby preventing the unlocking member 5 from interfering with the slot wall of the slot 321 during the movement of the locking member 3.

[0087] like Figure 7-Figure 9 As shown, the clamp assembly further includes a cover head 6. The cover head 6 can be connected to the center of the cover body 1 by means of screws or the like, so as to facilitate the user to hold and lift the pressure cooker cover 10. Each locking member 3 is slidably connected to the cover head 6, and the cover head 6 forms a mounting seat for the locking member 3, which can reduce the number of parts and fully utilize the internal space of the cover head 6, thereby improving the compactness of the overall structure.

[0088] Furthermore, the pressure cooker cover 10 further includes a shield 7. The shield 7 is detachably connected to the upper part of the cover 1, for example, the shield 7 is connected to the guide column of the cover 1 by fasteners such as screws. A part of the clamp 2 is clamped between the shield 7 and the cover 1, so that the clamp 2 is reliably connected to the cover 1 to prevent the clamp 2 from falling off the cover 1 during use.

[0089] Furthermore, the shield 7 extends along the surface of the cover body 1 in a direction close to the axis of the cover body 1, and the shield 7 and the surface of the cover body 1 together form a channel 71. The flexible traction member 4 is inserted into the channel 71, which can not only limit and guide the flexible traction member 4 to prevent the flexible traction member 4 from being exposed and damaged, but also improve the appearance of the pressure cooker cover 10.

[0090] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
