Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of small household appliances, and in particular to a pot cover structure and a cooking utensil having the same. Background Art
[0002] The cooking utensil generally comprises a pot body assembly and a cover body assembly, wherein the pot body assembly is provided with pot teeth, and the cover body assembly is provided with a locking structure and a transmission member. During the use of the cooking utensil, the cover body assembly can be switched between a locked position and an unlocked position, and the switching of the cover body assembly between the locked position and the unlocked position is achieved by the transmission member driving the movement of the locking structure, and the connection between the transmission member and the locking structure is achieved by a driving column and a driving groove.
[0003] In the related art, the driving column is generally arranged on the locking structure, and the driving slot is generally arranged on the transmission member. The driving slot is generally a strip-shaped hole with a constant width, so that when the locking structure is in the locking position, that is, when the locking structure is clamped with the pot teeth, due to a certain error in the manufacturing of the locking structure and the pot teeth, the driving column or the driving slot may still move when the locking structure is in the locking position, thereby causing the locking structure to collide with the pot teeth, affecting the normal use of the cooking utensil. Summary of the invention
[0004] The main purpose of the present invention is to provide a pot cover structure and a cooking utensil having the same, so as to solve the problem in the related art that the locking structure collides with the pot teeth due to excessive movement of the locking structure.
[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided a pot cover structure, comprising: a surface cover; an inner lining, installed below the surface cover; a locking structure, arranged below the inner lining, the locking structure having a locking position and an unlocking position; a transmission member, movably arranged on the inner lining and driving the locking structure to switch between the unlocking position and the locking position, the transmission member having a recovery position and a pulling position, when the transmission member is in the recovery position, the locking structure is located at the unlocking position, and when the transmission member is in the pulling position, the locking structure is located at the locking position; a linkage structure, comprising a plug-in driving column and a driving groove, one of the driving column and the driving groove is arranged on the locking structure, and the other of the driving column and the driving groove is arranged on the transmission member; wherein the driving groove comprises a driving section and a yielding section, the width of the yielding section is greater than the width of the driving section, and when the transmission member moves from the recovery position to the pulling position, the driving column moves from the driving section to the yielding section.
[0006] According to the technical solution of the present invention, a lining is provided below the face cover. A locking structure is also provided below the lining, and the locking structure has a locking position and an unlocking position. A movable transmission member is also provided on the lining, and the transmission member has a recovery position and a pulling position, and the transmission member can drive the locking structure to switch between the unlocking position and the locking position. When the transmission member is at the recovery position, the locking structure is at the unlocking position, and when the transmission member is at the pulling position, the locking structure is at the locking position. The linkage structure includes a plug-in drive column and a drive groove, one of the drive column and the drive groove is provided on the locking structure, and the other of the drive column and the drive groove is provided on the transmission member. The drive groove includes a driving end and a yielding section, and the width of the yielding section is greater than the width of the driving section. When the transmission member moves from the recovery position to the pulling position, the drive column moves from the driving section to the yielding section. Through the above-mentioned arrangement, the lining provides an installation position for the locking structure, so that the movement of the locking structure is more stable. The transmission member provided on the inner lining can transmit the force from the user to the locking structure, and then drive the locking structure to switch between the unlocking position and the locking position. When the transmission member moves from the recovery position to the pulling position, the locking structure moves from the unlocking position to the locking position. The linkage structure connects the transmission member and the locking structure together, so that the transmission member can drive the movement of the locking structure. The driving column and the driving slot make the overall structure of the linkage structure simpler. With the cooperation of the driving column and the driving slot, the transmission member can more effectively drive the locking structure to move between the unlocking position and the locking position. The width of the yielding section is greater than the width of the driving section, so that after the driving column enters the yielding section from the driving section, the transmission member moves from the recovery position to the pulling position, and the driving column still has a certain range of movement in the driving groove, that is, after the locking structure is in the locking position, the relative position between the locking structure and the transmission member can also be changed, thereby avoiding the locking structure from colliding with the pot teeth, that is, when the locking structure is in the locking position, even if the transmission member continues to be pulled, since the driving column is in the yielding section at this time, the driving column and the yielding section will not move synchronously, and the locking structure will not continue to move, which effectively ensures the user experience of the cooking utensil. Therefore, the technical solution of the present application effectively solves the problem of collision between the locking structure and the pot teeth caused by excessive movement of the locking structure in the related art.
[0007] Furthermore, when the locking structure is in the locked position, there is a gap between the driving column and the end of the yielding section away from the driving section. Through the above arrangement, when the locking structure is in the locked position, the driving column still has a movable space in the yielding section, so that the relative position of the locking structure and the transmission member can also be changed, thereby avoiding the locking structure in the locked position driven by the transmission member to continue to move and cause the locking structure to collide with the pot teeth of the cooking utensil.
[0008] Further, the driving section includes a straight slot section, the yielding section includes a slot body and a first convex portion, the straight slot section is connected to the slot body, the first convex portion is located at the end of the slot body away from the straight slot section, and the first convex portion extends toward the outside of the liner and protrudes from the straight slot section. The straight slot section enables the transmission member to effectively drive the locking structure when the locking structure moves from the unlocking position to the locking position, and the movement of the locking structure is more stable. The slot body can continue to drive the driving column, and because the first convex portion is provided, the first convex portion and the driving column are arranged to avoid each other, thus avoiding the locking structure from continuing to move and causing the locking structure to collide with the pot teeth, thereby improving the service life of the pot cover structure. The provision of the first convex portion enables the relative position between the driving column and the slot body to be changed when the locking structure is in the locking position, thus avoiding the relative movement of the driving column and the slot body from driving the movement of the locking structure. The first convex portion extends toward the outside of the liner and protrudes from the straight slot section, so that the driving column has a larger range of activity space.
[0009] Furthermore, the yielding section further comprises a second protrusion, which protrudes toward the inner side of the liner and is connected to the straight groove section. The second protrusion protrudes toward the inner side of the liner, so that after the driving column moves from the driving section to the yielding section, the driving column has a larger moving space in the yielding section, thereby avoiding the unsmooth movement of the locking structure caused by the manufacturing error of the cover assembly.
[0010] Furthermore, the second convex portion includes a first straight wall section, a second straight wall section, and a curved wall section arranged between the first straight wall section and the second straight wall section, the first straight wall section is arranged adjacent to the straight groove section, and a first angle A1 is formed between the first straight wall section and the straight groove section, and the range of the first angle A1 is between 110° and 170°. The first straight wall section can guide the movement of the driving column, and also make the movement of the driving column smoother, thereby avoiding the problem of damage to the driving column caused by a sharp change in force when the driving column enters the yielding section from the driving section. The second straight wall section limits the movement of the driving column from the outside to the inside of the lining, thereby avoiding the driving column from moving too far to the inside of the lining. The curved wall section enables a smooth transition at the junction of the first straight wall section and the second straight wall section, thereby avoiding the collision of the driving column with the second straight wall section when the driving column moves from the first straight wall section to the second straight wall section, thereby affecting the service life of the driving column. The first included angle A1 between the first straight wall section and the straight groove section is in the range of 110° to 170°, so that the driving column has a larger moving space in the avoidance section.
[0011] Furthermore, there is a second angle A2 between two adjacent side walls of the second convex portion, and the second angle A2 is greater than 90°. The second angle A2 is greater than 90°, that is, there is an obtuse angle between the first straight wall section and the second straight wall section, so that when the drive column moves from the first straight wall section to the second straight wall section, it can avoid the drive column from being stuck between the first straight wall section and the second straight wall section. The second angle A2 also ensures that when the cover assembly is opened, the movement of the transmission member will not drive the movement of the drive column, that is, the locking structure will not move, so that the cover assembly can be more stably in the open state.
[0012] Furthermore, the distance between the center line of the straight groove section and the center line of the liner gradually decreases in the direction from the front end of the liner to the rear end of the liner. This arrangement makes the straight groove section tilted toward the inner side of the liner in the direction from the front end of the liner to the rear end of the liner, that is, when the driving column moves from the straight groove section to the avoidance section, the distance between the driving column and the center line of the liner gradually decreases, so that when the transmission member cooperates with the locking structure, the transmission member can drive the locking structure to move.
[0013] Furthermore, the third angle A3 between the center line of the straight groove section and the center line of the inner lining satisfies the first angle A1: A3>180°-A1. Such a setting makes it impossible for the side edge of the straight groove section not adjacent to the first straight wall section to be parallel, so that the driving column has a larger activity space in the groove body, avoiding excessive collision between the locking assembly and the pot teeth.
[0014] Furthermore, the transmission member includes a slide plate and a lug connected to the slide plate, the driving groove is arranged on the lug, the locking structure includes a caliper structure, and the driving column is arranged on the caliper structure. The driving groove moves with the movement of the lug, thereby driving the movement of the driving column, and the movement of the driving column drives the movement of the locking structure, so that the locking structure can switch between the unlocking position and the locking position, and also makes the movement of the locking structure more stable.
[0015] According to another aspect of the present invention, a cooking utensil is provided, comprising a pot cover structure, wherein the pot cover structure is the pot cover structure described above. The driving column in the pot cover structure described above has a larger moving space in the avoidance section, thereby avoiding the problem that after the locking structure is in the locked position, the excessive movement of the transmission member drives the excessive movement of the locking structure, thereby causing the locking structure to collide with the pot teeth. The cooking utensil having the pot cover structure described above also has the above advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the pot cover structure includes: a surface cover 10, a lining 20, a locking structure 30, a transmission member 40, and a linkage structure 50. The lining 20 is installed below the surface cover 10. The locking structure 30 is arranged below the lining 20, and the locking structure 30 has a locking position and an unlocking position. The transmission member 40 is movably arranged on the lining 20 and drives the locking structure 30 to switch between the unlocking position and the locking position. The transmission member 40 has a recovery position and a pulling position. When the transmission member 40 is in the recovery position, the locking structure 30 is located in the unlocking position. When the transmission member 40 is in the pulling position, the locking structure 30 is located in the locking position. The linkage structure 50 includes a drive column 51 and a drive slot 52 that are plug-in matched. One of the drive column 51 and the drive slot 52 is arranged on the locking structure 30, and the other of the drive column 51 and the drive slot 52 is arranged on the transmission member 40. The driving slot 52 includes a driving section 521 and a yielding section 522 . The width of the yielding section 522 is greater than that of the driving section 521 . When the transmission member 40 moves from the recovery position to the pulling position, the driving column 51 moves from the driving section 521 to the yielding section 522 .
[0031] The technical solution of this embodiment is applied, and a lining 20 is arranged below the face cover 10. A locking structure 30 is also arranged below the lining 20, and the locking structure 30 has a locking position and an unlocking position. A movable transmission member 40 is also arranged on the lining 20, and the transmission member 40 has a recovery position and a pulling position, and the transmission member 40 can drive the locking structure 30 to switch between the unlocking position and the locking position. When the transmission member 40 is located at the recovery position, the locking structure 30 is located at the unlocking position, and when the transmission member 40 is located at the pulling position, the locking structure 30 is located at the locking position. The linkage structure 50 includes a drive column 51 and a drive groove 52 that are plug-in matched, one of the drive column 51 and the drive groove 52 is arranged on the locking structure 30, and the other of the drive column 51 and the drive groove 52 is arranged on the transmission member 40. The drive groove 52 includes a drive section 521 and a yield section 522, and the width of the yield section 522 is greater than the width of the drive section 521. When the transmission member 40 moves from the recovery position to the pulling position, the driving column 51 moves from the driving section 521 to the yielding section 522. Through the above-mentioned arrangement, the lining 20 provides an installation position for the locking structure 30, so that the movement of the locking structure 30 is more stable. The transmission member 40 arranged on the lining 20 can transmit the force from the user to the locking structure 30, and then drive the locking structure 30 to switch between the unlocking position and the locking position. When the transmission member 40 moves from the recovery position to the pulling position, the locking structure 30 moves from the unlocking position to the locking position. The linkage structure 50 connects the transmission member 40 and the locking structure 30 together, so that the transmission member 40 can drive the movement of the locking structure 30. The driving column 51 and the driving slot 52 make the overall structure of the linkage structure 50 simpler. Under the cooperation of the driving column 51 and the driving slot 52, the transmission member 40 can more effectively drive the locking structure 30 to move between the unlocking position and the locking position. The width of the yielding section 522 is greater than the width of the driving section 521, so that after the driving column 51 enters the yielding section 522 from the driving section 521, the transmission member 40 moves from the recovery position to the pulling position, and the driving column 51 still has a certain range of movement in the driving groove 52, that is, after the locking structure 30 is in the locking position, the relative position between the locking structure 30 and the transmission member 40 can also be changed, thereby avoiding the locking structure 30 from colliding with the pot teeth, that is, when the locking structure 30 is in the locking position, even if the transmission member 40 continues to be pulled, since the driving column 51 is in the yielding section 522 at this time, the driving column 51 and the yielding section 522 will not move synchronously, thereby preventing the locking structure 30 from continuing to move, thus effectively ensuring the user experience of the cooking utensil. Therefore, the technical solution of this embodiment effectively solves the problem of the locking structure colliding with the pot teeth due to excessive movement of the locking structure in the related art.
[0032] Preferably, the driving column 51 is a cylinder, so that the driving column 51 can slide more smoothly in the driving groove 52.
[0033] Specifically, a receiving cavity and a receiving portion are provided below the liner 20 , a part of the structure of the receiving portion protrudes out of the receiving cavity, and the locking structure 30 is movably provided in the receiving portion.
[0034] like Figure 3 As shown, in this embodiment, when the locking structure 30 is in the locked position, there is a gap between the driving column 51 and the end of the yielding section 522 away from the driving section 521. Through the above arrangement, when the locking structure 30 is in the locked position, the driving column 51 still has a movable space in the yielding section 522, that is, the relative position of the driving column 51 and the driving groove 52 can be changed, and then the relative position of the locking structure 30 and the transmission member 40 can also be changed, so as to avoid the locking structure 30 in the locked position driven by the transmission member 40 to continue to move and cause the locking structure 30 to collide with the pot teeth of the cooking utensil.
[0035] like Figures 2 to 5 As shown, in this embodiment, the driving section 521 includes a straight slot section 5211, and the yielding section 522 includes a slot body 5221 and a first convex portion 5222. The straight slot section 5211 is connected to the slot body 5221, and the first convex portion 5222 is located at the end of the slot body 5221 away from the straight slot section 5211. The first convex portion 5222 extends toward the outside of the liner 20 and protrudes from the straight slot section 5211. The straight slot section 5211 enables the transmission member 40 to effectively drive the locking structure 30 when the locking structure 30 moves from the unlocking position to the locking position, and the movement of the locking structure 30 is more stable. The groove body 5221 provides a space for the driving column 51, and also enables the groove body 5221 to continue to drive the driving column 51 after the locking structure 30 reaches the locking position. In addition, due to the provision of the first convex portion 5222, the first convex portion 5222 and the driving column 51 are arranged to avoid each other, thus avoiding the locking structure 30 from continuing to move and causing the locking structure 30 to collide with the pot teeth, thereby improving the service life of the pot cover structure. The provision of the first convex portion 5222 enables the relative position between the driving column 51 and the groove body 5221 to be changed when the locking structure is in the locking position, thus avoiding the relative movement of the driving column 51 and the groove body 5221 to drive the movement of the locking structure 30, thereby avoiding the locking structure 30 from colliding with the pot teeth, thereby affecting the service life of the cooking utensil. The first convex portion 5222 extends toward the outside of the liner 20 and protrudes from the straight groove section 5211, so that the driving column 51 has a larger range of activity space.
[0036] like Figure 5As shown, in this embodiment, the yielding section 522 further includes a second protrusion 5223, which protrudes toward the inner side of the liner 20, and the second protrusion 5223 is connected to the straight groove section 5211. The second protrusion 5223 protrudes toward the inner side of the liner 20, so that after the driving column 51 moves from the driving section 521 to the yielding section 522, the driving column 51 has a larger moving space in the yielding section 522, thereby avoiding the unsmooth movement of the locking structure 30 caused by the manufacturing error of the cover assembly.
[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the second protrusion 5223 includes a first straight wall section 52231, a second straight wall section 52232, and a curved wall section 52233 disposed between the first straight wall section 52231 and the second straight wall section 52232. The first straight wall section 52231 is disposed adjacent to the straight groove section 5211. There is a first angle A1 between the first straight wall section 52231 and the straight groove section 5211, and the first angle A1 ranges from 110° to 170°. The first straight wall section 52231 can guide the movement of the driving column 51, and also makes the movement of the driving column 51 smoother, thereby avoiding the problem of damage to the driving column 51 caused by a sharp change in force when the driving column 51 enters the yielding section 522 from the driving section 521. The second straight wall section 52232 limits the movement of the driving column 51 from the outside to the inside of the liner 20, thereby preventing the driving column 51 from moving too far inside the liner 20, thereby driving the locking structure 30 to move too far inside the liner 20, thereby causing the locking structure 30 to collide with the pot teeth. The curved wall section 52233 allows a smooth transition at the junction of the first straight wall section 52231 and the second straight wall section 52232, thereby preventing the driving column 51 from colliding with the second straight wall section 52232 when moving from the first straight wall section 52231 to the second straight wall section 52232, thereby affecting the service life of the driving column 51. The first angle A1 between the first straight wall section 52231 and the straight groove section 5211 is in the range of 110° to 170°, that is, in the direction in which the driving column 51 moves from the driving section 521 to the yielding section 522, the distance between the first straight wall section 52231 and the center of the lining 20 gradually decreases, so that when the transmission member 40 cooperates with the locking structure 30, the transmission member 40 can drive the locking structure 30 to move.
[0038] Specifically, the first angle A1 is 161°, so that when the driving column 51 moves from the straight groove section 5211 to the curved wall section 52233 , the force applied to the driving column 51 changes less, which is beneficial to improving the service life of the driving column 51 .
[0039] Preferably, the projection of the curved wall section 52233 on the liner 20 is an arc, and the radius of the arc is 3 mm. Of course, in an embodiment not shown in the figure, the curved wall section 52233 can also be a plurality of curves smoothly connected. There is an arc transition with a radius of 3 mm at the junction of the first convex portion and the second straight wall section. There is an arc transition with a radius of 5 mm at the junction of the first convex portion 5222 and the straight groove section 5211.
[0040] like Figure 4 and Figure 5 As shown, in this embodiment, there is a second angle A2 between two adjacent side walls of the second protrusion 5223, and the second angle A2 is greater than 90°. The second angle A2 is greater than 90°, that is, there is an obtuse angle between the first straight wall section 52231 and the second straight wall section 52232, so that when the driving column 51 moves from the first straight wall section 52231 to the second straight wall section 52232, it can avoid the driving column 51 from being stuck between the first straight wall section 52231 and the second straight wall section 52232, thereby affecting the movement of the locking structure 30. The second angle A2 also ensures that when the cover assembly is opened, the movement of the transmission member 40 will not drive the movement of the driving column 51, that is, the locking structure 30 will not move, so that the cover assembly can be more stably in the open state.
[0041] Preferably, the second angle A2 is 124°. In this way, when the driving column 51 moves from the first straight wall section 52231 to the second straight wall section 52232 , the force applied to the driving column 51 changes less, which is beneficial to improving the service life of the driving column 51 .
[0042] like Figures 3 to 5 As shown, in this embodiment, the distance between the center line of the straight groove section 5211 and the center line of the liner 20 gradually decreases in the direction from the front end of the liner 20 to the rear end of the liner 20. In the direction from the front end of the liner 20 to the rear end of the liner 20, the distance between the center line of the straight groove section 5211 and the center line of the liner 20 gradually decreases, that is, in the direction from the front end of the liner 20 to the rear end of the liner 20, the straight groove section 5211 is inclined toward the inner side of the liner 20, so that the driving column 51 is in the process of moving from the straight groove section 5211 to the yielding section 522, the distance between the driving column 51 and the center line of the liner 20 is gradually reduced, thereby allowing the locking structure 30 to move from the unlocking position to the locking position.
[0043] like Figures 3 to 5As shown, in this embodiment, the third angle A3 between the center line of the straight groove section 5211 and the center line of the inner liner 20 satisfies the first angle A1: A3>180°-A1. Such a setting makes the side of the straight groove section 5211 not adjacent to the first straight wall section 52231 have an angle, that is, the side of the straight groove section 5211 not adjacent to the first straight wall section 52231 cannot be parallel, so that the driving column 51 has a larger activity space in the groove body 5221, avoiding excessive collision between the locking assembly and the pot teeth.
[0044] Specifically, the driving column 51 has three movement directions in the driving groove 52, and the angle between the first movement direction and the center line of the liner 20 is the same as the third angle A3. The second movement direction is the center line direction of the liner 20. The angle between the third movement direction and the first movement direction is the first angle A1. When the locking structure 30 is in the locked state, the movable distance of the driving column 51 in the second direction is not less than 0.5 mm.

The above arrangement enables the slide plate 41 to drive the movement of the locking structure 30 through the lug 42, specifically, the driving groove 52 moves with the movement of the lug 42, the movement of the driving groove 52 drives the movement of the driving column 51, and the movement of the driving column 51 drives the movement of the locking structure 30, so that the locking structure 30 can switch between the unlocking position and the locking position, and also makes the movement of the locking structure 30 more stable.
[0046] Specifically, the caliper structure 31 includes a first caliper and a second caliper, each of which includes a flat plate portion and a cover tooth portion connected to the flat plate portion, and the cover tooth portion is connected to the outer edge of the flat plate portion. The cover tooth portion includes a plurality of cover tooth portions, and a plurality of cover tooth portions are arranged at intervals at the outer edge of each flat plate portion. The cover tooth portion is arc-shaped, and includes a lower convex portion connected to the flat plate portion and an inner flange connected to the lower convex portion, and the inner flange is located below the flat plate portion. The outer edge of the flat plate portion includes an arc portion and a straight portion, and the cover tooth portion is connected to the arc portion. The lug 42 includes a first lug and a second lug, and the first lug and the second lug are located at the same end of the slide plate 41 and are arranged at intervals, the first lug is connected to the first caliper in driving connection, and the second lug is connected to the second caliper in driving connection. The first end of the swing link is connected to the first lug, and the second lug is located on the side of the swing link facing the slide plate 41.
[0047] Specifically, the pot cover structure also includes a metal cover, an inner pot cover, a plurality of mounting brackets, an elastic member, a guide structure, a push-out member, an exhaust pipe, a pressure limiting valve, a swing member, a movable connection structure, a guide member, an electromagnetic valve, a detection device, a swing part, a flexible pulling member, a trigger member, a rotating rod and a first guide groove. The metal cover is arranged between the inner pot cover and the liner 20, and the inner pot cover is arranged below the liner 20. A plurality of mounting brackets are arranged on the metal cover. The elastic member is arranged between the mounting bracket and the liner 20 so that the mounting bracket can move up and down. The guide structure is arranged between the mounting bracket and the caliper structure 31, and the extension direction of the guide structure coincides with the diameter direction of the metal cover. The push-out member is connected to the transmission member 40 and moves synchronously with the transmission member 40, and the push-out member includes a push-out rod, the first end of the push-out rod is connected to the lug 42, and the second end of the push-out rod is matched with the first end of the swing member for pushing. The exhaust pipe is arranged on the liner 20 and the surface cover 10. The pressure limiting valve is installed at the top of the exhaust pipe and has a blocking position for blocking the exhaust pipe and a first avoidance position for avoiding the exhaust pipe. The pressure limiting valve is located at the rear end of the transmission member 40, and the push member extends toward the rear end of the transmission member 40 and cooperates with the pressure limiting valve to push. The swing member is rotatably connected to the liner 20, and the second end of the push rod is connected to the first end of the swing member through a movable connection structure, and the second end of the swing member is matched with the pressure limiting valve to push.

The guide member is arranged between the push rod and the liner 20. The electromagnetic valve is arranged between the push member and the pressure limiting valve, and the push member drives the electromagnetic valve so that the electromagnetic valve drives the pressure limiting valve. The locking structure 30 is driven by the transmission member 40, and the movement of the transmission member 40 can drive the movement of the push member. When the transmission member 40 is in the recovery position, the locking structure 30 is in the unlocking position, and when the transmission member 40 is in the pulling position, the locking structure 30 is in the locking position. The exhaust pipe passing through the lining 20 and the cover 10 can release the pressure in the pot body. The pressure limiting valve can control the gas in the pot body to be released through the exhaust pipe. When the pressure limiting valve is in the blocking position, the exhaust pipe is blocked by the pressure limiting valve, and the gas cannot be released through the exhaust pipe. When the pressure limiting valve is in the avoidance position, the pressure limiting valve will not block the exhaust pipe, and the gas can be released through the exhaust pipe. When the transmission member 40 is in the recovery position, the push member can push the pressure limiting valve to make the pressure limiting valve in the avoidance position, and the gas can be released through the exhaust pipe. In this way, when closing the cover, the gas in the pot body can always be discharged through the exhaust pipe, which will not affect the closing operation.
[0048] The first end of the swing part is movably connected with the transmission member 40, and the second end of the swing part is located in the vertical space where one end of the lining is away from the ejection rod. The detection device includes a detection member and a sensor, one of which is arranged on the second end of the swing part, and the other of which is arranged on the lining 20. The swing part is swingably arranged on the lining 20, and a first connecting part is arranged between the first end of the swing part and the transmission member 40. The second connecting part is arranged between the swing part and the lining 20, and the transmission member 40 can drive the locking structure 30 to switch between the locking position and the unlocking position when it moves, so that the lid can be opened and closed, and when the locking structure 30 is in the locking position, the connection between the pot cover structure and the pot body is relatively stable. When the transmission member 40 moves to move the locking structure 30 from the unlocking position to the locking position, the swing part swings so that the detection structure can realize detection, that is, when the locking structure 30 is in the locking position, the detection structure can realize detection, and then it can remind the user whether the locking structure 30 is completely in the locking position. And because the distance between the first end of the swinging part and the second connecting part is smaller than the distance between the second end of the swinging member and the second connecting part, when the transmission member moves and drives the first end of the swinging member to move a smaller distance, it can drive the second end of the swinging member to move a larger distance, that is, when the locking structure 30 is in the unlocking position, the relative distance of the detection structure is farther, so that no false detection will occur, thereby improving the accuracy of the detection.
[0049] Preferably, the distance between the first end of the swing part and the second connection part and the distance between the second end of the swing part and the second connection part satisfy the distance between the second end of the swing part and the second connection part ≥ 1.5×the distance between the first end of the swing part and the second connection part.

[0054] The pivot shaft is arranged on the inner liner 20 , and the pivot hole is arranged on the swinging part. The pivot hole is a second strip-shaped hole. When the swinging part swings, the pivot shaft moves in the second strip-shaped hole.
[0055] The swinging part is a swinging link, and a evasion part is provided on the swinging link, and the evasion part is located between the second connection part and the second end of the swinging link. The first end of the swinging link is connected to the first lug, and the second lug is located on the side of the swinging link facing the slide plate 41. A strip convex rib is provided on the lining 20, and the strip convex rib is located below the swinging part, and the extension direction of the strip convex rib is the same as the movement direction of the second end of the swinging part.
[0056] A flexible pulling member is arranged between the rear end of the transmission member 40 and the lining 20 to keep the transmission member 40 in the recovery position. The trigger member is driven and matched with the transmission member 40, and the trigger member is hinged on the pot body. The middle part of the rotating rod is hinged on the lining 20, and the first end of the rotating rod is abutted and matched with an end of the transmission member 40 where the lug 42 is not arranged. The first guide groove is arranged on the side of the lining 20 facing the face cover 10, and the transmission member 40 is movably arranged in the first guide groove, and the extension direction of the first guide groove is the same as the movement direction of the slide plate 41. The setting of the first guide groove can effectively reduce the thickness of the lining 20.
[0057] The flexible pulling member can pull the transmission member 40, that is, the flexible pulling member can drive the transmission member 40 to move from the pulling position to the recovery position, and make the multiple locking structures 30 in the unlocked position. When the transmission member 40 moves from the recovery position to the pulling position, the flexible pulling member is stretched. In this process, the elongation direction of the flexible pulling member is the same as the movement direction of the transmission member 40, so there is no need to guide the flexible pulling member. When the flexible pulling member shortens, it drives the transmission member 40 to move from the pulling position to the recovery position. In this process, the shortening direction of the flexible pulling member is also fixed, that is, there is no need to guide the flexible pulling member. Therefore, the above-mentioned setting can avoid setting a guide structure on the flexible pulling member, so that the flexible pulling member can always provide a reset force.
[0058] Specifically, in this embodiment, the pot cover structure further includes a stopper link and a stopper rod, the stopper link is movably arranged on the inner lining and has a stop position located above the stopper rod and a second avoidance position avoiding the stopper rod, the stopper link is located in the guide groove and below the sliding member, and the stopper link moves synchronously with the sliding member.

[0069] The flexible pulling member includes a plurality of tension springs arranged at intervals, the tension springs are located at the rear end of the transmission member 40, and the length of the tension springs when the transmission member 40 is in the extended position is greater than the length of the tension springs when the transmission member 40 is in the initial position. The sum of the elastic forces of the flexible pulling member is between 0.5N and 4N. The above elastic force can ensure that the transmission member is pulled into place, thereby placing the locking structure 30 in the unlocked position.
[0070] The trigger member drives the transmission member 40 to switch between the retracting position and the pulling position so that the caliper structure 31 switches between the unlocking position and the locking position.
[0071] The trigger member includes a rotating pendulum, the middle part of which is hinged on the pot body, the first end of the rotating pendulum is drivingly matched with the second end of the rotating rod, and the second end of the rotating pendulum is a driving end.

[0072] A guide rod and a second guide groove are also provided between the first guide groove and the inner liner, one of the guide rod and the second guide groove is provided on the inner liner, and the other of the guide rod and the guide groove is provided in the guide groove. A limit piece is also provided on the top of the guide rod, and a bolt hole for installing the limit piece is provided on the guide rod to prevent the transmission member 40 from being separated from the inner liner 20.

[0073] A clearance groove is arranged below the inner lining 20 , and the clearance groove is located at the edge of the accommodating cavity and at the side of the accommodating portion, and the clearance groove is arranged to avoid the inner pot cover.
[0074] like Figure 7 and Figure 8 As shown, according to another aspect of the present invention, a cooking utensil is provided, comprising a pot cover structure, wherein the pot cover structure is the pot cover structure described above. The driving column 51 in the pot cover structure described above has a larger moving space in the yielding section 522, thereby avoiding the problem that after the locking structure 30 is in the locked position, the excessive movement of the transmission member 40 drives the excessive movement of the locking structure 30, thereby avoiding the problem that the locking structure 30 collides with the pot teeth. The cooking utensil having the pot cover structure described above also has the above advantages.
[0075] Specifically, the cooking utensil further includes a pot body. The trigger member further includes a button, which is arranged on the pot body, and includes a main body and a connecting rod connected to a first end of the main body, the second end of the main body is hingedly connected to the pot body, a connecting hole is arranged on the pot body, a part of the structure of the main body extends out of the connecting hole, and an end of the connecting rod away from the main body is abutted and matched with the second end of the rotating swing arm.
[0076] A connecting rod is also provided in the vertical space between the detection member and the slide plate 41 . The connecting rod is fixed on the slide plate 41 , and a check valve is provided below the connecting rod.
[0077] When the slide plate 41 moves from the recovery position to the pulling position, the caliper structure 31 moves from the unlocking position to the locking position, and the driving column 51 moves from the straight groove section 5211 to the yielding section 522 along the first movement direction until it moves to the intersection of the straight groove section 5211 and the first protrusion 5222. At this time, the caliper structure 31 is in the locking position, that is, the caliper structure 31 is completely in contact with the pot teeth, the detection part cannot detect the signal, and the cooking utensil cannot work. At the same time, the connecting rod part structure is located directly above the check valve. If the detection part fails, the check valve is blocked by the connecting rod when the cooking utensil is working, and the internal pressure of the cooking utensil cannot rise and cannot work. When the driving column 51 moves to the first protrusion 5222, the detection part detects the signal, the connecting rod is completely separated from the check valve, and no longer affects the movement of the check valve. The pot cover structure is in a locked state, that is, when the pot cover structure is locked, the caliper structure 31 is in the locking position in front and the detection part detects in the back.
[0078] When the slide plate 41 moves from the pulling position to the recovery position, the driving groove 52 causes the relative position of the driving column 51 and the slide plate 41 to move from the second movement direction to the first movement direction. During this process, the driving column 51 does not move, that is, the caliper structure 31 does not move, and the sensing component is away from the detection component. The cooking appliance will prompt that the pot cover structure is not in a locked state and the cooking appliance cannot work normally. Release the button, the driving column 51 returns to the intersection of the straight groove section 5211 and the first protrusion 5222, and the sensing component also returns to the locked position of the pot cover structure, and the cooking appliance can work normally. If the detection part is damaged and the sensing part is away from the detection part but the machine can still work normally, there are protection measures. When the slide plate 41 moves to the position where the first straight wall section 52231 and the second straight wall section 52232 are in contact with the driving column 51, the connecting rod is fixed on the slide plate 41 and is also driven to move backward. Moreover, the connecting rod part structure is located directly above the check valve. At this time, the cooking utensil works normally. The connecting rod prevents the check valve from completely floating up and the cooking utensil cannot generate pressure to avoid danger. That is, when the pot cover structure is opened, the detection part detects in front and the caliper structure 31 moves behind.
[0079] When the pot cover structure is opened, the tension spring is subject to little resistance and generates instantaneous acceleration, causing the driving column 51 to move along the driving groove 52 from the second straight wall section 52232 to the straight groove section 5211, and the caliper structure 31 moves from the locked position to the unlocked position, thereby realizing the opening of the pot cover structure.
