[0037] 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.

[0038] 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.

[0039] 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.

[0041] 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.

[0042] like Figures 1 to 3 As shown, the cooking device of the first embodiment is an electric pressure cooker. The cooking device comprises a pot body 10, a pot cover 30 and a lid closing buffer structure. The pot body 10 is used to hold the food to be cooked. A heating device is arranged in the pot body 10. The pot cover 30 is arranged on the pot body 10 in a flippable manner. When the pot cover 30 is closed, the lid closing buffer structure applies a force to the pot cover 30 in the opposite direction of the closing direction of the pot cover 30 to slow down the closing speed of the pot cover 30. The pot cover 30 has a closed position where it is closed on the pot body 10 and an open position where it is opened relative to the pot body 10. The pot cover 30 is provided with an open cover structure 70. When the pot cover 30 is in the closed position, the lid closing buffer structure applies a force to the pot cover 30 and makes the pot cover 30 have a tendency to move from the closed position to the open position. When the pot cover 30 is in the closed position and the open cover structure 70 is in the unlocked state, the lid closing buffer structure cannot open the pot cover 30.

[0043] The cooking utensil of the present embodiment is provided with a lid closing buffer structure. When the pot lid 30 is closed, the lid closing buffer structure applies a force to the pot lid 30 in the opposite direction of the closing direction of the pot lid 30 to slow down the closing speed of the pot lid 30, thereby relieving the force of the pot lid 30 in the process of flipping and falling, thereby reducing the closing force of the pot lid 30, preventing injuries to the user's fingers, and ensuring safety of use.

[0044] It should be noted that when the pot cover 30 is in the closed position, although the cover closing buffer structure applies a force to the pot cover 30 so that the pot cover 30 has a tendency to move from the closed position to the open position, the force applied by the cover closing buffer structure to the pot cover 30 is not enough to open the pot cover 30, which requires the user to manually lift the pot cover 30 or use other cover opening drive structures to open the pot cover 30. In addition, the type of cooking appliance is not limited to the electric pressure cooker. In other embodiments not shown in the figure, the cooking appliance can be other types of cooking appliances, for example, the cooking appliance can be an electric rice cooker.

[0045] like Figures 1 to 3 As shown, in the cooking utensil of the first embodiment, the cover closing buffer structure is an elastic structure. The elastic structure is arranged between the pot body 10 and the pot cover 30. In this embodiment, the pot cover 30 is flippably arranged on the pot body 10 through the connecting shaft 60. The elastic structure is a torsion spring 40 sleeved on the connecting shaft 60. The torsion spring 40 has a first torsion arm 41 and a second torsion arm 42. The first torsion arm 41 is fixed on the pot body 10. The second torsion arm 42 is fixed on the pot cover 30 to apply a force opposite to the closing direction of the pot cover 30 to the pot cover 30. During the closing process of the pot cover 30, the torsion spring 40 always applies a force opposite to the closing direction to the pot cover 30 through the second torsion arm 42, thereby reducing the closing force and closing speed of the pot cover 30, and the structure of the torsion spring 40 is simple, easy to assemble, and can save installation space. The torsion spring 40 is sleeved on the connecting shaft 60, which is convenient for arrangement, and can make the structure more compact, further saving installation space.

[0046] It should be noted that when the pot cover 30 is fully opened relative to the pot body 10 (i.e., the pot cover 30 is in the open position), the second torsion arm 42 of the torsion spring 40 still exerts a certain force on the pot cover 30 in the opposite direction to the closing direction, so that the pot cover 30 remains in the open position. Of course, in other embodiments, when the pot cover is fully opened relative to the pot body, the force exerted on the pot cover by the second torsion spring arm of the torsion spring can be zero.

[0047] In the present embodiment, the number of torsion springs 40 is one, of course, the number of torsion springs is not limited thereto, and in other embodiments not shown in the figures, the number of torsion springs can be selected as needed. In addition, the specific form of the lid closing buffer structure is not limited to the torsion spring, and in other embodiments not shown in the figures, the lid closing buffer structure can be other structures that can apply a force opposite to the closing direction of the pot lid to the pot lid to slow down the closing speed of the pot lid. For example, the lid closing buffer structure can be a damping block arranged at the rear end of the pot lid and / or the pot body, and during the closing process of the pot lid, the damping block can frictionally slow down the closing speed of the pot lid; or, the lid closing buffer structure can be a buffer spring arranged between the pot lid and the pot body, and during the closing process of the pot lid, the buffer spring can apply a force opposite to the closing direction to the pot lid, and the buffer spring can be arranged at the front end of the pot lid and the pot body, or at the rear end of the pot lid and the pot body near the rotating shaft.

[0048] like Figure 1 As shown, in the cooking utensil of the first embodiment, the pot cover 30 includes a cover 32, an inner lining 31 and a locking cover arranged in sequence from top to bottom. The locking cover can be driven to rotate relative to the inner lining 31 by turning the handle. The locking cover is provided with a cover tooth, and the pot body 10 is provided with a pot tooth. When the locking cover is turned, the cover tooth and the pot tooth are buckled, thereby locking the pot cover 30 on the pot body 10. No additional locking structure is provided between the pot cover 30 and the pot body 10. When the lid needs to be opened, the elastic force applied by the torsion spring 40 to the pot cover 30 is not enough to make the pot cover 30 overcome its own gravity. At this time, the user needs to manually turn up the pot cover 30 and put it in the opening position. In this embodiment, the pot body 10 includes a shell 11, a heat preservation cover 12 and an inner pot arranged in sequence from outside to inside. The top edge of the heat preservation cover 12 is turned outward to form a flange, and the flanged part forms the pot tooth. Of course, the formation method of the pot tooth is not limited to this. In other embodiments not shown in the figure, the pot tooth can be set at the top edge of the inner pot.

[0049] like Figures 1 to 3 As shown, in the cooking utensil of the first embodiment, a first fixing structure is provided on the lining 31, and the second torsion arm 42 is fixed on the lining 31 through the first fixing structure. The first fixing structure can limit and fix the second torsion arm 42, thereby ensuring a reliable connection between the second torsion arm 42 and the lining 31.

[0050] like Figures 1 to 3As shown, in the cooking utensil of the first embodiment, the first fixing structure includes a first through hole 313 provided on the liner 31. The center line of the first through hole 313 is provided along the radial direction of the liner 31. The second torsion arm 42 is provided in the first through hole 313. Since the second torsion arm 42 of the torsion spring 40 is usually in the shape of a straight rod, the setting position of the first through hole 313 is more convenient for cooperation with the second torsion arm 42, and the second torsion arm 42 is limited by passing through the first through hole 313, which is more convenient for assembly. In the present embodiment, there are a plurality of first through holes 313, and the plurality of first through holes 313 are spaced apart along the radial direction of the liner 31. The plurality of first through holes 313 can enhance the effect of limiting and fixing. Of course, the form of the first fixing structure is not limited thereto. In other embodiments not shown in the figure, the first fixing structure may be a limiting structure of other forms.

[0051] like Figure 2 and Figure 3 As shown, in the cooking utensil of the first embodiment, a second fixing structure is provided on the pot body 10, and the first torsion arm 41 is fixed on the pot body 10 through the second fixing structure. The above-mentioned second fixing structure can limit and fix the first torsion arm 41, thereby ensuring the reliable connection between the first torsion arm 41 and the pot body 10. In this embodiment, the second fixing structure includes a second through hole provided on the pot body 10, and the first torsion arm 41 is passed through the second through hole. The first torsion arm 41 is limited by passing through the second through hole, which is more convenient for assembly. Among them, the second through hole can be directly formed on the pot body 10, or formed between the pot body 10 and an additional part. Of course, the form of the second fixing structure is not limited to this. In other embodiments not shown in the figure, the second fixing structure can be a limiting structure of other forms.

[0052] like Figures 1 to 3 As shown, in the cooking utensil of the first embodiment, the pot body 10 also includes a shell body 11 and a heat preservation cover 12 arranged in the shell body 11, and the pot body 10 also includes a middle plate 112 arranged above the shell body 11 and the heat preservation cover 12. A rotating shaft fixing frame 50 is arranged at the rear end of the middle plate 112. The connecting shaft 60 is mounted on the rotating shaft fixing frame 50. The second fixed structure is arranged below the rotating shaft fixing frame 50, so that the force point for limiting the first torsion arm 41 can be moved downward, thereby ensuring the reliability of limiting the first torsion arm 41 and facilitating the arrangement. Of course, the setting position of the second fixed structure is not limited to this. In other embodiments not shown in the figure, the second fixed structure can be arranged at the rotating shaft fixing frame.

[0053] like Figure 4 and Figure 5As shown, the cooking utensil of the second embodiment comprises a pot body 10, a pot cover 30 and a cover-closing buffer structure. Among them, the cover-closing buffer structure is an elastic structure. The pot body 10 is used to hold the food to be cooked. The pot cover 30 is rotatably arranged on the pot body 10, and the pot cover 30 has a cover-closing position covering the pot body 10 and an open position opened relative to the pot body 10, and the pot cover 30 is provided with an open cover structure 70. The elastic structure is arranged between the pot body 10 and the pot cover 30. When the pot cover 30 is in the cover-closing position, the elastic structure applies elastic force to the pot cover 30, and makes the pot cover 30 have a tendency to move from the cover-closing position to the open cover position. When the pot cover 30 is in the cover-closing position and the open cover structure 70 is in the unlocked state, the elastic structure cannot open the pot cover 30. When the pot cover 30 is in the open cover position, the elastic structure keeps the pot cover 30 in the open cover position.

[0054] In this embodiment, an elastic structure is provided between the pot cover 30 and the pot body 10. When the pot cover 30 is in the closed position and the lid opening structure 70 is in the unlocked state, the elastic structure cannot open the pot cover 30. When the pot cover 30 is in the open position, the elastic structure keeps the pot cover 30 in the open position. The above structure can keep the pot cover 30 in the open position and cannot fall back, further preventing the pot cover from falling and injuring the user. It should be noted that the lid opening structure 70 in this example is a lid opening handle, which can be rotated manually and has a locked position and an unlocked position. It can be understood by those skilled in the art that for an electric pressure cooker, when the lid opening handle is in the locked position, the pot cover 30 and the pot body 10 are locked, and the user cannot open the lid at this time. When the lid opening handle is in the unlocked position, the pot cover 30 can be opened relative to the pot body 10. In this embodiment, when the lid opening handle is in the unlocked state, the elastic force exerted by the elastic structure on the pot cover 30 is insufficient to enable the pot cover 30 to overcome its own gravity. At this time, the user needs to manually flip up the pot cover 30 and put it in the lid opening position. When the pot cover 30 is in the lid opening position, the elastic force exerted by the elastic structure on the pot cover 30 can keep the pot cover 30 in the lid opening position and prevent the pot cover 30 from falling and injuring the user.

[0055] like Figure 4 , Figure 7 as well as Figure 8 As shown, in the technical solution of embodiment 2, the elastic structure is a torsion spring 40 sleeved on the connecting shaft 60, and the torsion spring 40 includes a first torsion arm 41 and a second torsion arm 42. The first torsion arm 41 is fixed on the pot body 10, and the second torsion arm 42 is fixed on the pot cover 30.

[0056] like Figure 4 As shown, in the technical solution of the second embodiment, there is one torsion spring 40. The elastic force generated by one torsion spring 40 can keep the pot cover 30 in the open position. Of course, there can also be multiple torsion springs 40.

[0057] like Figure 5 and Figure 6 As shown, in the technical solution of the second embodiment, the pot body 10 includes a shell 11 and a heat preservation cover 12 arranged in the shell 11, and the pot body 10 also includes a middle plate 112 arranged above the shell 11 and the heat preservation cover 12, and a second fixing structure is arranged on the heat preservation cover 12, and the first torsion arm 41 is fixed to the heat preservation cover 12 through the second fixing structure. By fixing the first torsion arm 41 to the heat preservation cover 12 through the second fixing structure, on the one hand, no additional structure is required, saving costs, and on the other hand, the heat preservation cover 12 is a metal part with high structural strength and stable fixation. Therefore, the technical solution of this embodiment solves the problems of unstable connection between the torsion spring arm and the pot body of the electric pressure cooker in the prior art and high product cost.

[0058] It should be noted that those skilled in the art can understand that the torsion spring structure includes a spiral section and two torsion arms extending from both ends of the spiral section. The two torsion arms provide elastic force. Figure 8 As shown, Figure 8 The structure diagram of the torsion spring in the present embodiment when no force is applied is shown. The first torsion arm 41 is fixed on the heat-insulating cover 12, and the second torsion arm 42 is fixed on the pot cover 30. When the pot cover 30 is in the closed state, the second torsion arm 42 is pressed forward and is in a horizontal position. At this time, the second torsion arm 42 applies elastic force to the pot cover 30 and makes the pot cover 30 have a tendency to open automatically relative to the pot body 10.

[0059] like Figure 6 As shown, in the technical solution of the second embodiment, the second fixing structure is a second through hole 20 formed on the heat preservation cover 12. Specifically, the first torsion arm 41 is inserted into the second through hole 20 and the first torsion arm 41 is fixed. The above structure is easy to assemble and can be fixed reliably.

[0060] like Figure 6 As shown, in the technical solution of the second embodiment, the second through hole 20 is a long hole, and the second through hole 20 extends along the circumferential direction of the heat insulation cover 12. The above structure enables the first torsion arm 41 to have an installation margin in the left and right directions, thereby preventing the spiral structure in the middle from being twisted and squeezed when installing the first torsion arm 41.

[0061] like Figure 6 As shown, in the technical solution of the second embodiment, the heat preservation cover 12 includes a heat preservation cover body 121 and a flange 122 arranged at the upper edge of the heat preservation cover body 121, and the second through hole 20 is arranged on the flange 122. Specifically, the heat preservation cover body 121 is in the shape of a pot, and the flange 122 is a flange structure folded outward, and the flange 122 is arranged at the upper edge of the heat preservation cover body 121. By arranging the second through hole 20 on the flange 122, the structure of the heat preservation cover body 121 can be preserved, and the structural strength of the heat preservation cover body 121 can be ensured, thereby ensuring the service life of the product.

[0062] like Figure 4 , Figure 5 and Fig. 9 As shown, in the technical solution of the second embodiment, the pot body 10 further includes a bottom shell 113 connected to the lower side of the housing 11. A power board and other structures are arranged in the bottom shell 113. The bottom end of the bottom shell 113 is placed on the ground.

[0063] like Figure 5 , Fig. 9 and Fig.10 As shown, in the technical solution of the second embodiment, the pot body 10 further includes a middle plate 112 arranged above the shell 11 and the heat preservation cover 12, a rotating shaft fixing frame 50 is arranged on the middle plate 112, the torsion spring 40 is fixed on the rotating shaft fixing frame 50, and the second through hole 20 is arranged below the rotating shaft fixing frame 50. Specifically, a rotating shaft is arranged on the rotating shaft fixing frame 50, and the spiral structure of the cover opening torsion spring 40 is sleeved on the rotating shaft. The rotating shaft fixing frame 50 is arranged at the rear side of the middle plate 112. Further, from Figure 4 It can be seen that the middle plate 112 is arranged on the upper side of the housing 11. The middle plate 112 is roughly in the shape of a frustum from top to bottom, and the heat preservation cover 12 is connected below the middle plate 112.

[0064] like Figure 6 As shown, in the technical solution of the second embodiment, the middle plate 112 and the flange 122 are connected by a connecting member. Specifically, the connecting member is a connecting screw. The bottom of the flange 122 and the middle plate 112 are both provided with connecting holes, and the connecting screws are inserted into the connecting holes. Of course, the connection method between the middle plate 112 and the flange 122 is not limited to screw connection, and the two can also be connected by other methods, such as welding, bonding, etc.

[0065] like Figure 5 and Fig. 9 As shown, in the technical solution of the second embodiment, the pot body 10 further includes an inner pot 13 disposed on the middle plate 112.
