Description

Technical Field

[0001] The present invention relates to the technical field of pressure cookers, and more particularly, to a pressure cooker. Background Art

[0002] Currently, the widely used lid-opening method for pressure cooker products on the market is screw-on lid opening. The existing screw-on lid opening pressure cooker includes a lid, a pot body, and a handle that cooperates with them.

[0003] The anti-misoperation mechanism of the existing pressure cooker mainly relies on the cooperation between the lid teeth and the pot body teeth. Generally, there are large and small teeth on the lid, and a limit stop is provided on one of the large teeth. The pot body is provided with large and small teeth that cooperate with the lid teeth, and the size of one of the large teeth is smaller than that of the other large teeth and cooperates with the limit stop on the lid. Due to the limit stop, the lid can only be buckled with the pot body within the range of one large tooth on the pot body. However, the limit stop of the above structure cannot completely prevent the lid from being buckled on the pot body in other directions, which may lead to an unsafe state of the lid and the pot body. Summary of the Invention

[0004] The main object of the present invention is to provide a pressure cooker to solve the problem of unsafe factors existing when the pot body and the lid of the pressure cooker in the prior art are matched.

[0030] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions is enlarged, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0031] As Figures 1 to 5 shown, the pressure cooker of this embodiment includes: a pot body 10, a pot lid 20, and a limiting structure 30. The pot lid 20 can rotate around the pot body 10 to be fastened to or unlocked from the pot body 10. The pot body 10 includes a pot body main body 11 and a pot body handle 12 provided on the pot body main body 11. A groove 100 is formed between the pot body handle 12 and the pot body main body 11. The peripheral edge of the pot lid 20 extends downward to form a pot lid edge, and the pot lid edge is received in the groove 100. A pressing member is further provided on the outer side of the pot lid edge. The limiting structure 30 is installed on the pot body handle 12, and the limiting structure 30 includes a driving member and a slider 32 connected to the driving member. The slider 32 slides between a first position and a second position within the pot body handle 12, and the slider 32 can abut against the pot lid edge at the first position.

[0032] Applying the technical solution of this embodiment, when the pot lid 20 and the pot body 10 are engaged, the pressing member presses the driving member, and the driving member drives the slider 32 to slide from the first position to the second position to avoid the edge of the pot lid. In this way, the slider 32 will avoid the groove 100, and then the pot body main body 11 can enter into the groove 100. In this way, the pot lid 20 can rotate around the pot body 10 and be fastened to the pot body 10, which greatly improves the safety of the cooperation between the pot body 10 and the pot lid 20. The technical solution of this embodiment effectively solves the problem of unsafe factors existing when the pot body 10 and the pot lid 20 of the pressure cooker in the prior art are engaged. When the pot body 10 and the pot lid 20 are fastened, the pot teeth 13 of the pot body 10 and the lid teeth 23 of the pot lid 20 cooperate with each other. When the pot body 10 and the pot lid 20 are unlocked, the pot teeth 13 of the pot body 10 and the lid teeth 23 of the pot lid 20 are disengaged from each other.

[0033] As Figures 3 to 7 shown, in the technical solution of this embodiment, the limiting structure 30 further includes a reset elastic member 33. The first end of the reset elastic member 33 abuts against the inner wall of the pot body handle 12, and the second end of the reset elastic member 33 abuts against the slider 32 to apply an elastic force for the slider 32 to return to the first position. The setting of the reset elastic member 33 enables the slider 32 to automatically return to its position to press against the edge of the pot lid, so that the pot lid and the pot body cannot be engaged, which saves the operation of the operator, that is, the reset elastic member 33 enables the slider 32 to automatically reset without the operation of the operator. Specifically, the reset elastic member 33 is a spring, and the two ends of the spring are respectively clamped on the inner wall of the pot body handle 12 and the slider 32.

[0034] As Figures 3 to 8 shown, in the technical solution of this embodiment, the driving member is a link structure 31. The pot body handle 12 has a receiving space 200, and the limiting structure 30 is installed in the receiving space 200. The structure that the limiting structure 30 is installed in the receiving space 200 is compact, and there is no need to specially set an additional space to place the limiting structure 30.

[0035] As Figures 3 to 7 shown, in the technical solution of this embodiment, the pot lid 20 includes a pot lid main body 21 and a pot lid support portion 22. The pot lid support portion 22 is provided on the pot lid main body 21, and the pot lid support portion 22 is fixedly engaged with the pot body 10 and cannot rotate around the central axis of the pot lid main body 21. The pot lid main body 21 can rotate relative to the pot lid support portion 22 around the central axis of the pot lid main body 21. The pressing member is a pressing groove 222 provided on the pot lid support portion 22, and the pressing groove 222 cooperates with the driving member so that the pressing groove 222 presses the driving member. The separate settings of the pot lid main body 21 and the pot lid support portion 22, and the pot lid support portion 22 can be fixed, and the pot lid main body 21 can rotate relative to the pot lid support portion 22 around the central axis of the pot lid main body 21. In this way, the pot lid support portion 22 can be fixed first, and then the pot lid main body 21 can be rotated so that the pot lid main body 21 and the pot body 10 are fastened or unlocked.

[0036] As Figures 3 to 7 shown, in the technical solution of this embodiment, the link structure 31 includes a first link 311 and a second link 312 that are connected to each other. A pivot portion that is pivotally connected to each other is provided between the first end of the first link 311 and the first end of the second link 312, and the pivot portion is pivotally connected to the inner wall of the accommodation space 200. The second end of the first link 311 forms the free end of the link structure 31, and the second end of the second link 312 is pivotally connected to the slider 32. The link structure 31 formed by the connection of the first link 311 and the second link 312 has a relatively low processing cost and is convenient to set up. Specifically, the first link 311 drives the second link 312 to pivotally move, and the second link 312 pivotally drives the slider 32 to move. Through the above series of movements, the rotation of the first link 311 around the pivot portion is converted into the translational movement of the slider 32. Further specifically, the pivot portion is a pivot shaft provided on the main body of the first link 311. Of course, as those skilled in the art know, it is also possible that the pivot portion is a through-hole structure, and it is also possible to fix the pivot shaft through the first pivot portion on the pot body handle 12.

[0037] As Figures 3 to 7 shown, in the technical solution of this embodiment, the groove 100 is provided on the top surface of the pot body handle 12 facing the pot lid 20. The pot body handle 12 is further provided with a through groove 124 that communicates the groove 100 and the accommodation space 200. The free end of the link structure 31 passes through the through groove 124 and extends into the groove 100, and a part of the upper portion of the slider 32 is exposed from the through groove 124 and is located in the groove 100. The above structure is compactly arranged. The groove 100 and the accommodation space 200 are communicated through the through groove 124, so that the slider 32 can freely expand and contract between the accommodation space 200 and the groove 100.

[0038] As Figure 7 shown, in the technical solution of this embodiment, the pot body handle 12 includes a handle base 122 and a handle cover 123. The groove 100, the accommodation space 200, and the through groove 124 are all provided on the handle base 122. The handle cover 123 is detachably installed on the handle base 122 and seals the accommodation space 200 together with the handle base 122. The setting of the handle cover 123 facilitates the inspection, repair, and maintenance of the components inside the pot body handle 12.

[0039] As Figures 3 to 7As shown, in the technical solution of this embodiment, the slider 32 includes a slider base and a stop rib provided on the slider base. The slider base and the stop rib form a convex structure. The slider base slides within the accommodation space 200, and the stop rib slides with the slider base until part of it passes through the accommodation space 200 and is exposed within the groove 100. The convex structure formed by the slider base and the stop rib makes it difficult for the slider 32 to escape from the accommodation space 200. The thickness of the stop rib is adapted to the width of the through groove 124, and the width of the through groove 124 is smaller than the width of the slider base.

[0040] As Figure 1 shown, in the technical solution of this embodiment, the pot lid support portion 22 includes a central cover and two extension arms. The central cover is concentric with the pot lid body 21, and the central cover and the pot lid body 21 are connected by a connecting shaft. The two extension arms are respectively disposed on opposite sides of the central cover and the two extension arms are on the same diameter. The two extension arms have a downward flanging structure, and a fastening member for clamping with the flanging structure is provided on the pot lid body 21. The pot lid support portion 22 with the above structure uses less material, and the operator can also judge the matching situation between the pot lid 20 and the pot body 10 by observing the movement of the pot lid body 21.

[0041] As Figures 1 to 5 shown, in the technical solution of this embodiment, a rotation stop block 121 is provided on the pot body handle 12, and a rotation stop groove 221 is provided on the pot lid support portion 22 to position the pot lid 20 and the pot body 10. When the pot lid 20 is placed on the pot body 10, the rotation stop groove 221 and the rotation stop block 121 are aligned, and the rotation stop block 121 enters the rotation stop groove 221 for positioning. When the pot lid 20 and the pot body 10 are locked or unlocked, the pot lid body 21 is rotated and at this time the rotation stop groove 221 of the pot lid support portion 22 and the rotation stop block 121 are fixed, so that the pot lid support portion 22 does not rotate relative to the pot body 10. The setting of the rotation stop block 121 and the rotation stop groove 221 facilitates the positioning and fixing of the pot lid support portion 22 and the pot body 10. Of course, as is known to those skilled in the art, a structure in which a rotation stop block is provided on the pot lid support portion 22 and a rotation stop groove is provided on the pot body 10 is also possible.
