Technical Field

[0001] The present invention relates to the technical field of household small appliances, and more particularly, to a pot lid and a pressure cooker having the same. Background Art

[0002] There are many types of existing pressure cooker lid opening and closing mechanisms, which are mainly divided into drop lid type, screwing type, and clamp type. Since the screwing type pressure cooker has a simple structure, is easy to manufacture, and has a low cost, it is the most widely used and popular. Currently, the general basic structure of the existing screwing type pressure cooker is arranged between the upper handle and the lower handle of the pressure cooker. A push plate is provided in the upper handle. The push plate can slide back and forth in the upper handle. There is a stop foot at the lower part of the push plate, and a display stop lever is provided at the front part of the push plate. A push plate spring is provided between the push plate and the upper handle. The push plate spring acts on the push plate and the upper handle. A sliding foot is hinged on the push plate, and a torsion spring is provided between the push plate and the sliding foot. One end of the sliding foot can be pressed against a straight surface in the upper handle, and a slope is provided at the position corresponding to the other end of the sliding foot on the lower handle. By pushing the upper and lower handles to stagger or coincide, the pot lid is opened or closed, and the operation is inconvenient. Moreover, the structure of the existing screwing type pressure cooker is complex. When relative rotation occurs between the pot lid main body and the pot lid support part, it is not convenient to arrange components for driving the pot lid main body. Summary of the Invention

[0009] Further, a limiting portion is convexly provided on the closing plate, and the limiting portion restricts the sliding plate from swinging in a direction perpendicular to the linear movement direction of the sliding plate.

[0010] Further, the limiting portion includes a first limiting block and a second limiting block arranged in an alternating manner. Among them, the first limiting block is located between the second limiting block and the connecting shaft. The side end surface of the sliding plate facing the first limiting block and the second limiting block is a step. The first limiting block and the second limiting block respectively abut against the stepped side end surface, and the stepped side end surface can slide with the sliding plate to abut against the first limiting block to limit the moving distance of the sliding plate.

[0011] Further, a limiting hole is provided at the central portion of the sliding plate, and a through hole is provided on the closing plate.

[0026] 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, the thickness of layers and regions is enlarged for clarity, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0027] As Figures 1 to 5 shown, the pot lid of this embodiment includes: a pot lid main body 10, a pot lid support portion 20, a driving member 30, and a transmission structure 40. The pot lid opens and closes with the pot body 50. A lid tooth is provided on the pot lid main body 10. The pot lid support portion 20 is provided on the pot lid main body 10. The pot lid support portion 20 is snap-fitted with the pot body 50 to define circumferential rotation of the pot lid support portion 20, and the pot lid main body 10 can rotate relative to the pot lid support portion 20 about a connecting shaft 60. The driving member 30 is connected in cooperation with the transmission structure 40, and when the driving member 30 rotates, it drives the transmission structure 40 to perform a planar linear motion. A conversion connecting member 42 connects the transmission structure 40 and the pot lid main body 10. The conversion connecting member 42 moves together with the transmission structure 40 and drives the pot lid main body 10 to rotate about the central axis of the pot lid main body 10.

[0028] Applying the technical solution of this embodiment, the driving member 30 first drives the transmission structure 40 to perform a planar linear motion, and then the conversion connecting member 42 converts the planar linear motion into the rotation of the pot lid main body 10 around the central axis of the pot lid main body 10. The above structure improves the diversity of the transmission structure arranged in the pot lid, that is, it is more convenient when the structure and accommodation space in the pot lid are suitable for arranging this transmission structure. The technical solution of this embodiment effectively solves the problem that it is inconvenient to arrange the components directly driving the rotation of the pot lid main body 10 in the existing pot lid.

[0029] As Figure 2 , Figure 4 and Figure 5 shown, in the technical solution of this embodiment, the middle part of the pot lid main body 10 is connected to the pot lid support part through a connecting shaft 60. The transmission structure 40 includes a sliding plate 41 that performs a planar linear motion. The driving member 30 is connected to the sliding plate 41, and the conversion connecting member 42 connects the pot lid main body 10 and the sliding plate 41 to convert the planar linear motion of the sliding plate 41 into the rotation of the pot lid main body 10 around the connecting shaft 60. The above structure is compact and saves the space of the pot lid. Especially when the space in the pot lid is relatively small in the Y-axis direction, the sliding plate 41 can solve the problem of the rotation of the pot lid main body 10 relative to the pot lid support part 20. It is worth mentioning that the directions of the X-axis, Y-axis, and Z-axis are as Figure 2 shown. A control handle 32 is arranged on the pot lid support part 20, and the control handle 32 is connected to the transmission structure 40.

[0030] As Figure 2 , Figure 4 and Figure 5 shown, in the technical solution of this embodiment, the driving member 30 includes a first gear 31. A row of teeth is arranged on the sliding plate 41 along the Z-axis direction, or a rack extending along the Z-axis direction is arranged on the sliding plate 41, so that the first gear 31 drives the sliding plate 41 to move along the Z-axis direction. The structure in which the first gear 31 cooperates with the teeth or rack arranged on the sliding plate 41 makes the transmission ratio of the pot lid in this embodiment stable.

[0031] As Figure 2 and Figure 5 shown, in the technical solution of this embodiment, the conversion connecting member 42 is a rod-shaped structure. A movable long hole 43 is arranged on the sliding plate 41. The first end of the conversion connecting member 42 is fixedly connected to the pot lid main body 10, and the second end of the conversion connecting member 42 is movably connected in the movable long hole 43, so that the sliding plate 41 drives the pot lid main body 10 to rotate. The structure in which the movable long hole 43 cooperates with the rod-shaped structure makes the structure in which the pot lid main body 10 cooperates with the pot lid support part 20 relatively compact.

[0032] As Figure 4 and Figure 5As shown, in the technical solution of this embodiment, a movable long hole 43 is provided on the skateboard 41. The pot lid further includes a closing plate 21 located between the pot lid main body 10 and the skateboard 41. An arc-shaped guiding hole 211 is provided on the closing plate 21, and the distance from each point on the guiding hole 211 to the central axis of the pot lid main body 10 is equal. The conversion connecting piece 42 passes through the guiding hole 211 and is fixed to the pot lid main body 10. The movable long hole 43 exerts a force on the conversion connecting piece 42, and the guiding hole 211 avoids the movement track of the conversion connecting piece 42. In addition, the movable long hole 43 and the guiding hole 211 jointly limit the swing of the pot lid main body 10 during rotation.

[0033] As Figures 2 to 5 shown, in the technical solution of this embodiment, a limiting portion 22 is convexly provided on the closing plate 21, and the limiting portion 22 limits the swing of the skateboard 41 along the direction perpendicular to the linear movement direction of the skateboard 41. The above structure enables the skateboard 41 to move along a predetermined track, and further, the movable long hole 43 on the skateboard 41 drives the conversion connecting piece 42 to move. The above structure is compact and has a low processing cost.

[0034] As Figure 2 , Figure 4 and Figure 5 shown, in the technical solution of this embodiment, the limiting portion 22 includes a first limiting block 221 and a second limiting block 222. Among them, the first limiting block 221 is located inside, that is, closer to the connecting shaft 60. In this way, the first limiting block 221 and the second limiting block 222 are staggered and not on the same straight line. The skateboard 41 has a step, and the step has side edges along the X-axis and the Z-axis. When the skateboard 41 moves in the Z-axis direction, the first limiting block 221 cooperates with the two side edges of the step, and the second limiting block 222 cooperates with the side edge of the skateboard 41. The first limiting block 221 and the second limiting block 222 jointly limit the circumferential direction of the skateboard 41. The combined action of the first limiting block 221 and the second limiting block 222 limits both the linear movement and the rotation of the skateboard 41, enabling the skateboard 41 to move along a predetermined plane in a straight line. Specifically, the first limiting block 221 is provided at the vacant position of the step. The first limiting block 221 can not only limit the moving distance of the skateboard 41 in the Z-axis but also limit the swing in the X-axis direction.

[0035] As Figures 2 to 5 shown, in the technical solution of this embodiment, a kidney-shaped limiting hole 411 is provided at the central part of the skateboard 41. The closing plate 21 is provided with a through hole. The connecting shaft 60 passes through the limiting hole 411 and the through hole in sequence and is fixed to the pot lid main body 10 and the pot lid support portion 20 respectively. The limiting hole 411 can limit the extreme position of the movement of the skateboard 41. The above structure can achieve fixation and limitation at the same time. Such a structural design takes various factors into comprehensive consideration and is more convenient in actual use. Moreover, when the skateboard 41 moves, the connecting shaft 60 can slide relatively in the limiting hole 411 of the skateboard 41, avoiding the swing of the skateboard 41.

[0036] As Figures 2 to 5 shown, in the technical solution of this embodiment, the transmission structure 40 includes a slide plate 41 that moves in a planar straight line. The driving member 30 and the slide plate 41 are connected by a gear-rack fit. An elongated slot 43 is provided on the slide plate 41. The pot lid further includes a closing plate 21 located between the pot lid body 10 and the slide plate 41. An arc-shaped guiding hole 211 is provided on the closing plate 21. The distance from each point on the guiding hole 211 to the central axis of the pot lid body 10 is equal. One end of the conversion connecting member 42 is fixedly connected to the pot lid body 10, and the other end of the conversion connecting member 42 passes through the guiding hole and the elongated slot 43 in sequence and is fixed to the slide plate 41. The setting of the guiding hole 211 enables the closing plate 21 to avoid when the conversion connecting member 42 rotates around the central axis of the pot lid body 10. The cooperation between the elongated slot 43 and the guiding hole 211 prevents the conversion connecting member 42 from swinging. Specifically, the width of the elongated slot 43, the width of the guiding hole 211, and the diameter of the conversion connecting member 42 are adapted. The conversion connecting member 42 is a connecting rod, the connecting rod is vertically arranged, and a limiting portion with a diameter larger than the width of the elongated slot 43 is provided at the highest point of the connecting rod.

[0037] This application also provides a pressure cooker, including a pot body 50 and a pot lid that cooperates with the pot body 50. The pot lid is the above-mentioned pot lid. The pressure cooker of this application can realize opening or locking the pot lid with one hand.
