Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and in particular to a pot cover assembly and a cooking utensil having the same. Background Art

[0002] In many electric pressure cooker products of the related technology, the pot cover comprises a multi-layer structure, specifically including a surface cover, an inner lining, and a locking cover arranged in sequence from top to bottom. The locking cover can rotate relative to the inner lining, and the locking cover is provided with cover teeth that cooperate with the pot teeth of the pot body of the electric pressure cooker.

[0003] The process of opening and closing the lid of the electric pressure cooker is realized by rotating the handle to lock the lid, and the cover of the electric pressure cooker is fixed. The handle is generally rotated at an angle of about 45 degrees, and the handle and the lock cover are connected by a rotating rod.

[0004] In the related art, the rotating rod is rotatably assembled on the lining by screws, and the rotating rod itself can move. There are many uncertainties in fixing the rotating rod by screws. For example, during the assembly process, the force of screwing will affect the gap between the gasket and the rotating rod. Too much force will cause the gap between the gasket and the rotating rod to be too small or even no gap, causing greater resistance to the opening and closing of the cover; too little force will cause the screw to be not tightened, causing the handle to shake. Summary of the invention

[0005] The main purpose of the present invention is to provide a pot cover assembly and a cooking utensil having the same, so as to solve the problem in the related art that the gap between the transfer rod and the inner liner is too large or too small when the transfer rod is assembled on the inner liner by screws.

[0006] To achieve the above-mentioned purpose, according to one aspect of the present invention, a pot cover assembly is provided, comprising: a pot cover body, an arc-shaped hole is arranged on the pot cover body; a locking cover is rotatably mounted below the pot cover body, a connecting piece is arranged on the locking cover, and the connecting piece is inserted into the arc-shaped hole; a handle assembly, the handle assembly comprises a handle and a rotating rod, the handle drives the rotating rod to rotate relative to the pot cover body, the rotating rod is detachably connected to the pot cover body through a limiting structure, the rotating rod is connected to the connecting piece and drives the locking cover to rotate; wherein the limiting structure comprises a first limiting portion arranged on the pot cover body and a second limiting portion arranged on the rotating rod, the second limiting portion has a disassembly position and a limiting position relative to the first limiting portion, when the second limiting portion is in the disassembly position, the rotating rod and the second limiting portion can be separated from the first limiting portion and the pot cover body, and the rotating rod cannot be connected to the connecting piece, when the second limiting portion is in the limiting position, the rotating rod and the second limiting portion are limited by the first limiting portion, and the rotating rod can be connected to the connecting piece.

[0007] By applying the technical solution of the present invention, the second limiting part has a disassembly position and a limiting position relative to the first limiting part. The second limiting part and the rotating rod can be installed on the pot cover body through the disassembly position. The first limiting part will not interfere with the second limiting part. At this time, the rotating rod and the arc hole are staggered, so the rotating rod cannot be connected to the connecting member. The rotating rod is rotated in a clockwise or counterclockwise direction, and then the second limiting part is moved from the disassembly position to the limiting position. When the second limiting part is in the limiting position, the rotating rod overlaps with the arc hole, and the rotating rod can be connected to the connecting member. At this time, the rotating rod and the second limiting part are limited by the first limiting part, and the rotating rod cannot be separated from the pot cover body. Therefore, the limiting position is not a position, and the position of the second limiting part when the rotating rod overlaps with the arc hole can be called the limiting position. When the rotating rod is connected to the connecting member, the handle drives the rotating rod and the connecting member to rotate together, and the connecting member moves in the arc hole. In this way, the rotation range of the rotating rod is limited by the arc hole, so that when the second limiting part is always in the limiting position, the second limiting part will not move to the disassembly position, and the rotating rod and the second limiting part will not be separated from the first limiting part and the pot cover body. Therefore, through the above technical solution, the pot cover body and the rotating rod do not need screws to be assembled. Therefore, the technical solution of the present application can solve the problem of too large or too small gap when the rotating rod is assembled on the lining by screws in the related art.

[0008] Furthermore, the first limiting portion includes a positioning column and a stop convex edge arranged on the positioning column, and the second limiting portion includes a through hole arranged on the rotating rod, and the through hole can allow the positioning column and the stop convex edge to pass through, so that the rotating rod can be rotatably mounted on the positioning column. When the second limiting portion is in the disassembly position, the through hole is arranged corresponding to the positioning column and the stop convex edge. The above structure facilitates the stop convex edge to pass through the through hole, so that the disassembly and assembly of the rotating rod becomes smooth. When the second limiting portion is in the limiting position, the through hole and the stop convex edge are staggered. The above structure enables the stop convex edge to limit the movement position of the through hole along the direction of the rotation axis S of the rotating rod, and then the stop convex edge can block the rotating rod.

[0009] Furthermore, the positioning post is a cylinder, the width of the stop convex edge is smaller than the diameter of the positioning post, and the profile of the through hole is matched with the profile formed by the positioning post and the stop convex edge. The above-mentioned matching makes it difficult for the rotating rod to move relative to the pot cover body when the rotating rod rotates around the positioning post, thereby preventing the rotating rod from shaking.

[0010] Furthermore, the two stop ridges are located on opposite sides of the positioning column, and the two stop ridges are symmetrically arranged. The two stop ridges can simultaneously apply force to the rotating rod from two symmetrical directions, so that the force acting on the rotating rod becomes uniform.

[0011] Furthermore, a positioning platform is also provided on the pot cover body, and the positioning column is provided on the positioning platform. The positioning platform enables the rotating rod to be assembled at a predetermined assembly position, thereby improving the assembly efficiency of the rotating rod.

[0012] Furthermore, a friction-reducing rib is provided between the stop convex edge and the rotating rod. The friction-reducing rib can reduce the friction between the stop convex edge and the rotating rod, thereby reducing the resistance to the rotation of the rotating rod.

[0013] Furthermore, the pot cover body is lined, the rotating rod is provided with a connecting groove at the connection position with the connecting piece, and the connecting piece passes through the arc hole and the connecting groove in sequence. The connecting groove allows the connecting piece to have sufficient movement space when rotating with the rotating rod.

[0014] Furthermore, the first limiting portion includes a positioning column and a first baffle arranged at a distance from the positioning column, the rotating rod has a sleeve inserted on the positioning column, the second limiting portion is a second baffle arranged on the sleeve, and when the second limiting portion is in the disassembly position, the second baffle is staggered with the first baffle. The above structure facilitates the second baffle to be disengaged from the first baffle. The disassembly and assembly of the rotating rod becomes smooth. When the second limiting portion is in the limiting position, the second baffle is located below the first baffle. The above-mentioned first baffle and second baffle stopper cooperate to prevent the rotating rod from being separated from the pot cover body.

[0015] Furthermore, the first stopper includes an arc-shaped vertical plate arranged on the pot cover body and a flange arranged on the top of the arc-shaped vertical plate, a gap is formed between the flange and the pot cover body, and the second stopper is a convex portion arranged on the sleeve, and when the second limiting portion is in the limiting position, the convex portion is located in the gap. The above-mentioned convex portion can rotate between the flange and the pot cover body.

[0016] Furthermore, the first limiting part includes a positioning column and a stop convex edge arranged on the positioning column, and the second limiting part includes a through hole arranged on the rotating rod, and the through hole can allow the positioning column and the stop convex edge to pass through, so that the rotating rod can be rotatably mounted on the positioning column, when the second limiting part is in the disassembly position, the through hole is arranged corresponding to the positioning column and the stop convex edge, and when the second limiting part is in the limiting position, the through hole and the stop convex edge are staggered; the positioning column is a cylinder, the width of the stop convex edge is smaller than the diameter of the positioning column, and the contour of the through hole is adapted to the contour jointly formed by the positioning column and the stop convex edge; the stop convex edges are two located on opposite sides of the positioning column, and the two stop convex edges are symmetrically arranged; a positioning platform is also arranged on the pot cover body, and the positioning column is arranged on the positioning platform; a wear-reducing convex rib is arranged between the stop convex edge and the rotating rod; the pot cover body is a lining, and the rotating rod is provided with a connecting groove at the connection position with the connecting member, and the connecting member passes through the arc hole and the connecting groove in sequence.

[0017] According to another aspect of the present invention, a cooking utensil is provided, the cooking utensil is an electric pressure cooker, the cooking utensil comprises a pot cover assembly, and the pot cover assembly is the above-mentioned pot cover assembly. The above-mentioned cooking utensil can solve the problem of too large or too small gap when the transfer rod is assembled on the liner by screws in the related art.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0036] like Figures 1 to 3 As shown, the pot cover assembly of this embodiment includes: a pot cover body 10, a locking cover 20 and a handle assembly 30. The pot cover body 10 is provided with an arc hole 11. The locking cover 20 is rotatably mounted below the pot cover body 10, and a connecting member 21 is provided on the locking cover 20, and the connecting member 21 is penetrated in the arc hole 11. The handle assembly 30 includes a handle 40 and a rotating rod 50 driven by the handle 40, and the rotating rod 50 is detachably connected to the pot cover body 10 through a limiting structure 60, and the rotating rod 50 can rotate relative to the pot cover body 10, and the rotating rod 50 can be connected to the connecting member 21 and drive the locking cover 20 to rotate. Among them, the limiting structure 60 includes a first limiting portion provided on the pot cover body 10 and a second limiting portion provided on the rotating rod 50, and the second limiting portion has a disassembly position and a limiting position relative to the first limiting portion. When the second limiting portion is in the disassembly position, the rotating rod 50 and the second limiting portion can be separated from the first limiting portion and the pot cover body 10, and the rotating rod 50 cannot be connected to the connecting member 21. When the second limiting portion is in the limiting position, the rotating rod 50 and the second limiting portion are limited by the first limiting portion, and the rotating rod 50 can be connected to the connecting member 21.

[0037] By applying the technical solution of this embodiment, the second limiting portion has a disassembly position and a limiting position relative to the first limiting portion. The second limiting portion and the rotating rod are installed on the pot cover body 10 through the disassembly position. The first limiting portion will not interfere with the second limiting portion. At this time, the rotating rod and the arc hole are staggered ( Figure 4 2 shows the state where the rotating rod 50 and the arc hole 11 are offset), so the rotating rod 50 cannot be connected to the connecting member 21. The rotating rod 50 is rotated in the clockwise direction, so that the second limiting portion moves from the disassembly position to the limiting position. When the second limiting portion is in the limiting position, the rotating rod 50 overlaps with the arc hole 11 ( Figure 6 and Figure 8The rotating rod 50 and the arc-shaped hole 11 overlap (shown), the rotating rod 50 can be connected to the connecting member 21. At this time, the rotating rod 50 and the second limiting portion are limited by the first limiting portion, and the rotating rod 50 cannot be separated from the pot cover body 10. Therefore, the limiting position is not a position, and the position of the second limiting portion when the rotating rod 50 and the arc-shaped hole 11 overlap can be called the limiting position. When the rotating rod 50 is connected to the connecting member 21, the handle 40 drives the rotating rod 50 and the connecting member 21 to rotate together, and the connecting member 21 moves in the arc-shaped hole 11. In this way, the rotation range of the rotating rod 50 is limited by the arc-shaped hole 11, and then when the second limiting portion is always in the limiting position, the second limiting portion will not be rotated to the disassembly position, and the rotating rod 50 and the second limiting portion will not be separated from the first limiting portion and the pot cover body 10. Therefore, through the above technical solution, the pot cover body 10 and the rotating rod 50 do not need screws for assembly. Therefore, the technical solution of this embodiment can solve the problem of too large or too small gap when the rotating rod is assembled on the lining by screws in the related art. In addition, no screws are used to fix the rotating rod and the pot cover body, which can avoid the cost of increasing the process when screwing.

[0038] It should be noted that the “disassembly position” means that when the rotating rod 50 is disassembled or installed from the pot cover body 10, the second limiting portion can be in a disengaged state relative to the first limiting portion, that is, Figure 5 The disassembly and assembly positions are shown. According to the specific structure of the first limiting portion, the disassembly and assembly positions can be one or more. "Limiting position" refers to the position where the rotating rod 50 can be connected to the connecting member 21 when the rotating rod 50 rotates on the pot cover body 10. As mentioned above, the "limiting position" is not a position, and the position of the second limiting portion when the rotating rod 50 overlaps with the arc hole 11 can be called the limiting position. When the second limiting portion is in the limiting position, the first limiting portion limits the movement of the second limiting portion and the rotating rod 50 along the direction of the rotation axis S of the rotating rod 50.

[0039] In this embodiment, Figure 6 The rotating rod 50 and the connecting member 21 are shown to be in the first connecting position, at which time, the pot cover body 10 is in the open cover position. Figure 8 The rotating rod 50 and the connecting member 21 are shown to be in the second connecting position, at which time, the pot cover body 10 is in the closing position.

[0040] like Figures 10 to 12As shown, the first limiting portion includes a positioning column 63 and a stop ridge 61 disposed on the positioning column 63. The positioning column 63 and the stop ridge 61 have a simple structure and are easy to be processed and formed on the pot cover body 10. The second limiting portion includes a through hole 62 disposed on the rotating rod 50, and the through hole 62 allows the positioning column 63 and the stop ridge 61 to pass through, so that the rotating rod 50 can be rotatably mounted on the positioning column 63. When the second limiting portion is in the disassembly position, the through hole 62 is arranged corresponding to the positioning column 63 and the stop ridge 61, and when viewed from top to bottom along the direction of the rotation axis S of the rotating rod 50, the stop ridge 61 is located in the through hole 62 (as shown in FIG. 2 ). Figure 5 In this way, it is easy for the stop convex edge 61 to pass through the through hole 62, so that the assembly and disassembly of the rotating rod 50 becomes smooth. When the second limiting portion is in the limiting position, the through hole 62 and the stop convex edge 61 are staggered. When viewed from top to bottom along the rotation axis S of the rotating rod 50, the projections of the stop convex edge 61 and the through hole 62 on the pot cover body 10 are staggered (as shown in FIG. 1 ). Figure 7 or Fig. 9 In this case, the stopper 61 limits the movement of the through hole 62 along the rotation axis S of the rotating rod 50. Furthermore, the stopper 61 can stop the rotating rod 50, so that the rotating rod 50 is always in contact with the pot cover body 10. The connecting member 21 of this embodiment is preferably a columnar structure.

[0041] like Figure 5 and Fig.11 As shown, the positioning post 63 is a cylinder, the width of the stop convex edge 61 is smaller than the diameter of the positioning post 63, and the profile of the through hole 62 is adapted to the profile formed by the positioning post 63 and the stop convex edge 61. The stop convex edge 61 is preferably formed at the top of the side wall of the positioning post 63 and protrudes outward. After the stop convex edge 61 passes through the through hole 62, the rotating rod 50 is installed on the pot cover body 10. When the rotating rod 50 rotates on the pot cover body 10, the rotating rod 50 rotates around the positioning post 63. In addition, the above-mentioned profiles are adapted to make the clearance between the positioning post 63 and the through hole 62 fit, so that when the rotating rod 50 rotates around the positioning post 63, it is not easy for the rotating rod 50 to move relative to the pot cover body 10, and the rotating rod 50 is prevented from shaking, so that the rotating rod 50 can be stably rotated on the pot cover body 10. The above-mentioned “contour matching” means that, along the direction of the rotation axis S of the rotating rod 50, the projection of the positioning column 63 on the upper surface of the pot cover body 10 is located in the through hole 62, and the contour shape of the through hole 62 is similar to the contour shape jointly formed by the positioning column 63 and the stop flange 61.

[0042] like Figure 7 , Fig. 9 and Fig.11As shown, there are two stop ridges 61 located on opposite sides of the positioning column 63, and the two stop ridges 61 are symmetrically arranged. In this embodiment, the through hole 62 includes an arc segment located at the rotation axis S of the rotating rod 50 and a groove segment located on opposite sides of the arc segment. The two groove segments facilitate the two stop ridges 61 to pass through, and the arc segment cooperates with the positioning column 63 to facilitate the smooth rotation of the rotating rod 50 around the positioning column 63. In other embodiments not shown in the figures, the number of the stop ridges can be one, three or more.

[0043] In this embodiment, Figure 6 The connecting member 21 in the embodiment is limited by the arc hole 11, thereby limiting the rotation stroke of the rotating rod 50, so that the rotating rod 50 cannot be rotated to the disassembly position ( Figure 5 shown). Figure 8 The included angle between the stop protrusion 61 and the through hole 62 is relatively large, forming an approximately cross shape.

[0044] like Figure 2 and Fig.11 As shown, a positioning platform 711 is further provided on the pot cover body 10, and the positioning column 63 is provided on the positioning platform 711. When the rotating rod 50 is assembled on the pot cover body 10 along the positioning column 63, the positioning platform 711 enables the rotating rod 50 to be assembled at a predetermined assembly position, thereby improving the assembly efficiency of the rotating rod 50.

[0045] like Figure 2 and Fig.12 As shown, a friction-reducing rib 722 is provided between the stop convex edge 61 and the rotating rod 50. When the rotating rod 50 rotates on the pot cover body 10 around the positioning column 63, the friction between the stop convex edge 61 and the rotating rod 50 can be reduced by the friction-reducing rib 722, thereby reducing the resistance to the rotation of the rotating rod 50.

[0046] like Figure 3 and Figure 4 As shown, the pot cover body 10 is lined, and the rotating rod 50 is provided with a connecting groove 53 at the connection position with the connecting member 21, and the connecting member 21 passes through the arc hole 11 and the connecting groove 53 in sequence. In this embodiment, the rotating rod 50 includes a first end 51 and a second end 52, and the first end 51 rotates around the positioning column 63, and the connecting groove 53 is formed on the second end 52. When the first end 51 rotates, the connecting groove 53 allows the connecting member 21 to have sufficient activity space when rotating, so that the rotating rod 50 drives the locking cover 20 to rotate. The connecting groove 53 of this embodiment is preferably a long hole.

[0047] In this embodiment, the cooking utensil cover can be opened and closed only by rotating the rotating rod 50 90 degrees. When the rotating rod 50 exceeds the rotation range of 90 degrees, the connecting member 21 is used to limit the position. Specifically, the connecting member 21 moves in the arc-shaped hole 11 of the liner to control the locking cover 20 to rotate within a range of 45 degrees, that is, within the range of Figure 6 The cover opening position and Figure 8 The rotating rod 50 is located between the closing position shown in FIG. 1 and the closing position shown in FIG. 2. At any position of the remaining 90 to 360 degrees of the rotating rod 50, a stopper ridge 61, a positioning column 63 and a through hole 62 are provided between the rotating rod 50 and the inner liner. At the remaining 90 to 360 degrees, the through hole 62 has a disassembly position so that the stopper ridge 61 can pass through the through hole 62. After the rotating rod 50 and the inner liner are assembled, the rotating rod 50 is rotated to a certain angle, and during the rotation of the rotating rod 50, the rotating rod 50 will not be rotated to the disassembly position ( Figure 5 The rotating rod 50 is rotated in a manner that makes full use of the working principle of the rotating range of the rotating rod 50. The rotation of the rotating rod 50 of this embodiment is controlled by the handle 40, and the handle 40 is fixed to the rotating rod 50 by screws. Of course, the rotation of the rotating rod 50 can also be achieved by other mechanisms, such as motor drive.

[0048] In other embodiments not shown in the figures, the first limiting part includes a positioning column and a first baffle arranged at intervals with the positioning column, and the rotating rod has a sleeve inserted on the positioning column. The second limiting part is a second baffle arranged on the sleeve. This facilitates the second baffle to be installed along the positioning column, so that the rotating rod rotates around the positioning column. When the second limiting part is in the disassembly position, the second baffle is staggered with the first baffle, so that the second baffle is detached from the first baffle. When the second limiting part is in the limiting position, the second baffle is located below the first baffle. The first baffle includes an arc-shaped vertical plate arranged on the pot cover body and a flange arranged on the top of the arc-shaped vertical plate, and there is a gap between the flange and the pot cover body, and the second baffle is a convex part arranged on the sleeve, and when the second limiting part is in the limiting position, the convex part is located in the gap. In this embodiment, similarly, the second baffle and the rotating rod are installed on the pot cover body through the disassembly position, at this time, the rotating rod is staggered with the arc hole, so that the rotating rod cannot be connected to the connecting member. The rotating rod is rotated clockwise or counterclockwise to move the second baffle from the disassembly position to the limiting position. When the second baffle is at the limiting position, the rotating rod overlaps with the arc hole, and the rotating rod can be connected to the connecting member. At this time, the rotating rod and the second baffle are limited by the first baffle, and the rotating rod cannot be separated from the pot cover body.

[0049] Of course, in the embodiments not shown in other figures, the first limiting portion and the second limiting portion are not limited to the above-mentioned structures, as long as the first limiting portion and the second limiting portion satisfy the following conditions, that is, when the second limiting portion is in the disassembly position relative to the first limiting portion, the rotating rod and the second limiting portion can be separated from the first limiting portion and the pot cover body, and the rotating rod cannot be connected to the connecting member; when the second limiting portion is in the limiting position relative to the first limiting portion, the rotating rod and the second limiting portion are limited by the first limiting portion, and the rotating rod can be connected to the connecting member, they are all within the protection scope of the present application.

[0050] The present application also provides a cooking utensil. In this embodiment, the cooking utensil of this embodiment is an electric pressure cooker, and the cooking utensil includes a pot cover assembly, and the pot cover assembly is the above-mentioned pot cover assembly. The above-mentioned cooking utensil can solve the problem of too large or too small gap when the transfer rod is assembled on the lining by screws in the related art. Of course, in other embodiments not shown, the cooking utensil can also be an electric rice cooker, a low-pressure rice cooker, a soy milk machine, a food processor, an electric stew pot and other products.

[0051] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
