[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0058] Currently, with the development of technology and the improvement of people's living standards, more and more cooking utensils have appeared in kitchens to meet different cooking needs and preferences. These utensils not only improve cooking efficiency but also enrich the flavor and nutrition of food.

[0059] There are various types of cooking utensils, including electric rice cookers, pressure cookers, electric slow cookers, etc. Taking a pressure cooker as an example, the pressure cooker uses steam pressure to speed up the cooking process through a sealed way. The working principle of the pressure cooker is to seal the air in the pot, so that the steam cannot escape, thereby generating a higher pressure in the pot than the atmospheric pressure. This increased pressure can increase the boiling point of water, allowing food to be cooked at a higher temperature, thereby shortening the cooking time, while also preserving the nutritional content and flavor of the food.

[0060] However, whether it is a pressure cooker using open fire or an electric heating pressure cooker, the convenience and operability of its use are of most concern to users. In particular, the operation mode of the pressure cooker cover opening and closing directly affects the convenience of product use. The main components of the pressure cooker include the pot body and the upper cover for being openably and closably mounted on the pot body. The upper cover is equipped with various opening and closing structures with the pot body to adapt to different use requirements and safety standards, mainly including the falling cover type, the screwing type and the clamp type.

[0061] In the related art, when opening the cover, the user needs to first switch the pot cover from the locked position to the unlocked position, and then open the upper cover from the pot body through the handle assembly. When closing the cover, the user needs to first close the pot body through the handle assembly, and then switch the pot cover from the unlocked position to the locked position. This design is relatively cumbersome for the operation of the upper cover, and is not convenient for users to use.

[0062] Therefore, the embodiments of the present application provide an upper cover and a cooking utensil, aiming to improve the problem of not being simple enough in operation of the cooking utensil in the related art.

[0063] In the embodiments of the present application, the cooking utensil can include one of a pressure cooker, an electric rice cooker and an electric slow cooker, and the embodiments do not limit the specific type of the cooking utensil. In order to facilitate the description of the following content, the cooking utensil of the following embodiments is a pressure cooker, and the advantages of the cooking utensil of the present application are introduced in detail.

[0064] Taking the pressure cooker as an example, the pot body usually includes an outer pot and an inner pot. The inner pot is used to directly hold food and is detachably installed in the outer pot, which is convenient for users to clean and replace, and can also prevent users from directly contacting the surface of the heated inner pot, reducing the risk of burns. The outer pot can act as a heat preservation layer to reduce heat loss, allowing the food in the inner pot to be heated more quickly and evenly.

[0065] Please refer to Figures 1 to 3The upper cover 1 is coveringly arranged on the pot body. The upper cover 1 comprises a cover body 11, a pot cover 12, a handle assembly 13, an unlocking assembly 14, an elastic member 15 and a transmission assembly 16. The pot cover 12 is rotationally connected with the cover body 11 and is arranged in the cover body 11. The pot cover 12 has a locking position for locking with the pot body and an unlocking position for unlocking the locking with the pot body. The handle assembly 13 is movably arranged on the cover body 11 and can be switched between a holding position and a locking position. The unlocking assembly 14 is movably arranged on the cover body 11 and is used for unlocking or releasing the handle assembly 13. The elastic member 15 is connected with the handle assembly 13 and is used for driving the handle assembly 13 to switch from the locking position to the holding position. The transmission assembly 16 is in transmission connection with the handle assembly 13 and the pot cover 12. When the unlocking assembly 14 releases the handle assembly 13, the handle assembly 13 is driven by the elastic member 15 to switch from the locking position to the holding position. The handle assembly 13 drives the transmission assembly 16 to move and drive the pot cover 12 to rotate, so that the pot cover 12 switches from the locking position to the unlocking position.

[0066] It should be noted that the unlocking assembly 14 can be movably arranged on the cover body 11 in various ways. For example, the unlocking assembly 14 can be movably arranged on the cover body 11 by sliding. For example, the unlocking assembly 14 can be movably arranged on the cover body 11 by rotating. For example, the unlocking assembly 14 can be movably arranged on the cover body 11 by lifting. The unlocking assembly 14 can unlock the cover body 11 in various ways. For example, when the cover body 11 is connected with the pot body by a buckle and a buckle groove, the unlocking assembly 14 can drive the buckle to exit the buckle groove to unlock the cover body 11. For example, when the cover body 11 is connected with the pot body by a plug-in column and a plug-in groove, the unlocking assembly 14 can drive the plug-in column to exit the plug-in groove to unlock the cover body 11. Here, the specific unlocking modes are not listed one by one.

[0067] The pot cover 12 can be locked with the pot body in various ways. For example, the outer circumferential side of the pot cover 12 is provided with a thread, the inner side wall of the pot body is provided with a thread groove, the pot cover 12 is located at the locking position, the pot cover 12 and the pot body are locked by the cooperation of the thread and the thread groove, the pot body is located at the unlocking position, and the thread and the thread groove are arranged at intervals in the circumferential direction of the cover body 11. For example, the outer circumferential side of the pot cover 12 is provided with a buckle part, the inner side wall of the pot body is provided with a buckle groove, the pot cover 12 and the pot body are locked by the cooperation of the buckle part and the buckle groove, the pot body is located at the unlocking position, and the buckle part and the buckle groove are arranged at intervals. Here, the specific locking modes are not listed one by one.

[0068] The handle assembly 13 can be mounted on the cover 11 in various ways, such as sliding or rotating. The handle assembly 13 can have various shapes, such as an arch shape, a "7" shape, or other shapes that are easy for users to hold. The handle assembly 13 can be mounted on the transmission assembly 16 in various ways, such as being integrally formed, being connected by threads, or being connected by buckling. Preferably, the handle assembly 13 is detachably connected to the transmission assembly 16, so that when the handle assembly 13 or the transmission assembly 16 is damaged, only the corresponding part needs to be replaced, thereby reducing the maintenance cost.

[0069] The holding position and the locking position can be spaced apart in the horizontal direction, or in the vertical direction. If the handle assembly 13 is rotatably mounted on the cover 11, the holding position and the locking position can be spaced apart in the circumferential direction of the handle assembly 13.

[0070] The elastic member 15 can be a spring, or a magnetic member.

[0071] The transmission assembly 16 can be a gear set or a sliding block set, as long as it can transmit the movement of the handle assembly 13 to the rotation of the cover 12.

[0072] When the user needs to open the upper cover 1, the user releases the handle assembly 13 by operating the unlocking assembly 14. The handle assembly 13 is switched from the locking position to the holding position under the driving of the elastic member 15. In the switching process, the handle assembly 13 drives the transmission assembly 16 to move, thereby driving the cover 12 to switch from the locked position to the unlocked position. At this time, the user can open the upper cover 1 by operating the handle assembly 13.

[0073] When the user needs to close the upper cover 1, the user closes the upper cover 1 by operating the handle assembly 13, and switches the handle assembly 13 from the holding position to the locking position. At this time, the unlocking assembly 14 locks the handle assembly 13. In the switching process, the handle assembly 13 drives the transmission assembly 16 to move, thereby driving the cover 12 to switch from the unlocked position to the locked position.

[0074] The upper cover 1 and the cooking utensil provided by the embodiments of the present application have the following advantages. The user only needs to drive the unlocking assembly 14 to release the handle assembly 13, and the handle assembly 13 is switched from the locking position to the holding position under the driving of the elastic member 15. In the switching process, the handle assembly 13 drives the transmission assembly 16 to move to drive the pot cover 12 to switch from the locking position to the unlocking position. At this time, the user can open the upper cover 1 by operating the handle assembly 13. Therefore, the user only needs to drive the unlocking assembly 14 to switch the handle assembly 13 from the locking position to the holding position and switch the pot cover 12 from the locking position to the unlocking position, thereby simplifying the opening and closing cover operation steps of the cooking utensil, which facilitates the user to operate the cooking utensil. Meanwhile, after the unlocking assembly 14 releases the handle assembly 13, the elastic member 15 can stably maintain the handle assembly 13 in the holding position, thereby avoiding that the handle assembly 13 is separated from the holding position when the upper cover 1 is shaken.

[0075] For a better understanding of the present application, reference will be made to the following Figures 1 to 2 In some embodiments of the present application, the handle assembly 13 is rotationally installed on the cover body 11. In the process of switching the handle assembly 13 from the locking position to the holding position, the handle assembly 13 is tilted upward relative to the cover body 11. It can be understood that the rotation axis of the handle assembly 13 is perpendicular to the rotation axis of the pot cover 12. In this way, the handle assembly 13 is tilted upward relative to the cover body 11 when the handle assembly 13 is in the holding position, so that the user can hold the handle assembly 13 through the tilted part of the handle assembly 13, thereby facilitating the user to operate the upper cover 1.

[0076] Specifically, for a better understanding of the present application, reference will be made to the following Figures 3 to 5 In an embodiment of the present application, the handle assembly 13 comprises a holding handle 131 and a rotating shaft 132. The rotating shaft 132 extends in the horizontal direction, the rotating shaft 132 is in transmission connection with the transmission assembly 16, and the holding handle 131 is rotationally installed on the cover body 11 through the rotating shaft 132. The elastic member 15 is sleeved on the rotating shaft 132 and connected with the holding handle 131. It can be understood that the horizontal direction is perpendicular to the rotation axis of the pot cover 12, the rotating shaft 132 is perpendicular to the rotation axis of the pot cover 12, the rotating shaft 132 overlaps the rotation axis of the holding handle 131, and the holding handle 131 rotates around the rotating shaft 132. In this way, the rotating shaft 132 is sleeved on the rotating shaft 132 to drive the holding handle 131 to rotate through the elastic member 15, thereby eliminating the need to additionally set the installation structure of the elastic member 15, and further simplifying the structure of the upper cover 1. It should be noted that the elastic member 15 can be understood as a torsion spring. The torsion spring drives the holding handle 131 to rotate, one end of the torsion spring is connected with the holding handle 131, and the other end of the torsion spring is connected with the cover body 11.

[0077] Specifically, in another embodiment of the present application, the handle assembly 13 comprises a holding handle 131 and a rotating shaft 132, the rotating shaft 132 extends in a horizontal direction, the rotating shaft 132 is in driving connection with the transmission assembly 16, the holding handle 131 is rotatably installed on the cover 11 through the rotating shaft 132; the elastic member 15 is located between the holding handle 131 and the cover 11, one end of the elastic member 15 is in abutment with the cover 11, and the other end of the elastic member 15 is in abutment with the surface of the holding handle 131 facing the cover 11. In this way, the elastic member 15 is located between the holding handle 131 and the cover 11, so that when the handle assembly 13 is released by the unlocking assembly 14, the elastic member 15 drives the holding handle 131 to move away from the end of the rotating shaft 132 in a direction away from the cover 11, so that the end of the holding handle 131 away from the rotating shaft 132 is lifted out of the cover 11.

[0078] The elastic member 15 can be a spring, which drives the holding handle 131 to rotate through the elastic force of the spring. The elastic member 15 can also be a magnetic member, the holding handle 131 is made of a magnetic material repelling the magnetic member, or the holding handle 131 can be provided with a magnetic part made of a magnetic material repelling the magnetic member, which drives the holding handle 131 to rotate through the magnetic force of the magnetic member repelling the holding handle 131. Here, they will not be listed one by one.

[0079] Please refer to Figure 3 In some embodiments of the present application, the transmission assembly 16 comprises a connecting member 161, a transmission member 162 and a driven member 163, the connecting member 161 is installed on the handle assembly 13, the transmission member 162 is liftable installed on the cover 11, the transmission member 162 is in driving connection with the handle assembly 13, the driven member 163 is rotatably installed on the cover 11, the driven member 163 is in driving connection with the transmission member 162 and the pot cover 12, during the process of switching the handle assembly 13 from the locking position to the holding position, the handle assembly 13 drives the connecting member 161 to move, which drives the transmission member 162 to rise, the driven member 163 drives the driven member 163 to rotate to drive the pot cover 12 to rotate, so that the pot cover 12 is switched from the locked position to the unlocked position.

[0080] In this way, during the process of switching the handle assembly 13 from the locking position to the holding position, the connecting member 161 moves around the rotating shaft of the handle assembly 13 under the driving of the handle assembly 13, and drives the transmission member 162 to rise relative to the cover 11, the driven member 163 rotates under the driving of the transmission member 162, so as to drive the pot cover 12 to switch from the locked position to the unlocked position.

[0081] It should be noted that the transmission member 162 and the driven member 163 are in transmission connection to convert the movement in the vertical direction into the rotation of the pot cover 12. The transmission member 162 and the driven member 163 can be in the form of rack and pinion to convert the movement in the vertical direction into the rotation of the pot cover 12. The transmission member 162 and the driven member 163 can also be in the form of screw rod and gear to convert the movement in the vertical direction into the rotation of the pot cover 12. Here, they will not be listed one by one. For example, the transmission member 162 is in the form of a connecting rod and a rack. The connecting rod is installed on the cover body 11 in a lifting manner. One end of the connecting rod is in engagement with the rack to drive the rack to move in the horizontal direction. The driven member 163 includes a gear which is in engagement with the rack and is connected with the rotation center of the pot cover 12. The rack drives the gear to rotate through the movement of the rack. The gear drives the pot cover 12 to rotate through the rotation of the gear.

[0082] Specifically, please refer to Figure 3 One of the transmission member 162 and the driven member 163 is provided with an inclined sliding groove 164, and the other of the transmission member 162 and the driven member 163 is provided with a driving portion 165. When the transmission member 162 is lifted or lowered, the driving portion 165 is in engagement with the inclined sliding groove 164 to drive the driven member 163 to rotate. In this way, the transmission member 162 can drive the driven member 163 to rotate through the engagement of the driving portion 165 and the inclined sliding groove 164 when the transmission member 162 is lifted, so as to simplify the structure of the transmission assembly 16.

[0083] It can be understood that the transmission member 162 is provided with the inclined sliding groove 164, and the driven member 163 is provided with the driving portion 165. The driven member 163 is provided with the inclined sliding groove 164, and the driven member 163 is provided with the driving portion 165. The extension direction of the inclined sliding groove 164 includes a first component and a second component. The first component is in the vertical direction, and the second component is in the rotation direction of the driven member 163.

[0084] Further, please refer to Figure 5 The handle assembly 13 includes a handle cover 133 and a base 134. The base 134 and the handle cover 133 surround to form a mounting cavity 135. The base 134 is provided with an avoiding hole 136 which is in communication with the mounting cavity 135. The connecting member 161 is installed in the mounting cavity 135 and partially exposed from the avoiding hole 136 to be in transmission connection with the transmission member 162. In this way, the connecting member 161 is located between the handle cover 133 and the base 134, so that the handle cover 133 and the base 134 can protect the connecting member 161, and the connecting member 161 can better move with the handle assembly 13.

[0085] The handle cover 133 and the base 134 can be made of the same material, or can be made of different materials, which is not specifically limited herein. It can be understood that the cross section of the connecting piece 161 is larger than the avoiding hole 136, so as to avoid the connecting piece 161 from being separated from the mounting cavity 135. The mounting cavity 135 can have various shapes, and can be cylindrical or square, which is not specifically limited herein. Preferably, the shape of the mounting cavity 135 is the same as that of the connecting piece 161, so that the connecting piece 161 can be positioned by the mounting cavity 135.

[0086] Further, please refer to Figures 2 to 3 The surface of the base 134 facing the pot cover 12 is provided with a plurality of gripping grooves 134a, which are arranged at intervals along the extension direction of the base 134. In this way, the user can operate the handle assembly 13 by holding the plurality of gripping grooves, so as to facilitate the user to hold the handle assembly 13, and further facilitate the user to operate the upper cover 1.
