[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a cooking utensil. Background Art

[0002] One end of the pot lid of the one-piece cooking utensil is hinged and fixed to the pot body, and the other end is locked with the pot body. The pot body is usually provided with a lid opening assembly for controlling the unlocking of the pot body and the pot lid. The lid opening assembly includes a button and an unlocking member arranged inside the pot body. One end of the unlocking member is rotatably connected to the pot body so that it can swing around the connection, and the other end is provided with a tongue for buckling with the pot lid. When the user presses the button, the button generates a thrust on the unlocking member, driving the unlocking member to swing around the connection, thereby loosening the tongue from the pot lid and unlocking the pot lid.

[0003] In the prior art, the structure of the lid opening assembly generally includes a single lever structure and a double lever structure. Due to the limited space inside the pot body, the single lever structure makes it difficult to design the lever arms at both ends of the unlocking member, and the lid opening operation is more laborious. The double lever structure adds a transmission member, which amplifies the push of the button and transmits it to the unlocking member, thereby making the lid opening operation more labor-saving.

[0004] However, as the number of parts increases, the transmission parts and the unlocking parts need to be fixed to the pot body respectively, and the springs and other parts also need to be installed. The number of parts is large, the assembly process is complicated, and the assembly efficiency is low. Utility Model Content

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the utility model, the driving member and the transmission member are fixed to the fixed bracket, and the fixing of the fixed bracket to the pot body realizes the indirect fixing of the driving member and the transmission member to the pot body. Therefore, during assembly, it is not necessary to fix each component to the pot body in sequence, but first assemble the driving member, the transmission member, the elastic member and other components to the fixed bracket so that each component forms an integral assembly, and then fix the assembly as a whole to the pot body, thereby realizing the rapid assembly of the lid opening assembly and the pot body, which not only reduces the difficulty of assembly, but also greatly shortens the assembly time and improves the assembly efficiency. On the other hand, by installing components such as the driving member and the transmission member through a separate fixed bracket, the overall strength of the lid opening assembly is improved, the stability of the movement of each component is improved, and the reliability of the lid opening function is improved.

[0020] 2. As a preferred embodiment of the utility model, the driving member includes a driving shaft matched with the fixed bracket, a driving end located on one side of the driving shaft and a trigger end located on the other side of the driving shaft, the driving end is used to match with the operation button, the trigger end is used to drive the transmission member, and the distance between the driving end and the driving shaft is smaller than the distance between the trigger end and the driving shaft. In this embodiment, the driving shaft is closer to the driving end, so that the force arm between the driving end and the driving shaft is shorter, and the force arm between the trigger end and the driving shaft is longer. When the driving end is pressed, the lifting space of the trigger end can be guaranteed, the triggering effect of the driving member on the transmission member is improved, and the transmission member can respond to the movement of the operation button more quickly, thereby improving the sensitivity of opening the cover.

[0021] 3. As a preferred embodiment of the present invention, the transmission member includes a transmission shaft matched with the fixed bracket, a transmission end located on one side of the transmission shaft and an active end located on the other side of the transmission shaft, the transmission end is provided with a contact arc surface for matching with the driving member, and the active end is provided with a latch for matching with the pot cover. When one end of the driving member is pushed by the operating button and swings, it triggers the transmission end of the transmission member, pushing the transmission member to swing around the transmission shaft, and the driving member contacts the contact arc surface, so that the contact between the two is a line contact, thereby reducing the contact area between the two, reducing the friction between the two, making the movement of the transmission member smoother, and reducing the sticking feeling generated during the movement of the transmission member, improving the operating feel.

[0022] 4. As a preferred embodiment of the present invention, the pot cover includes a surface cover and an inner cover located inside the surface cover, the action end is located between the surface cover and the inner cover, and a stop protrusion is provided on the side of the action end facing the inner cover. When the inner cover is screwed together with the pot body, the inner cover cooperates with the stop protrusion to limit the swing of the transmission member. When the pot cover is screwed together with the pot body, the inner cover and the stop protrusion form a stop cooperation, and the transmission member cannot swing due to the stop of the inner cover, thereby limiting the transmission member to a state where the tongue is locked with the pot cover. In the pressure cooking device, after the pot cover is screwed together with the pot body, the user cannot open the cover by pressing the operation button, ensuring cooking in a safe environment.

[0023] 5. As a preferred embodiment of the utility model, the transmission member includes a transmission shaft, and the lid opening assembly also includes an elastic member. The transmission member is provided with a mounting position located on one side of the transmission shaft, and a driving position located on the other side of the transmission shaft. The mounting position is used to mount the elastic member, and the driving position is used to cooperate with the driving member for transmission. The distance between the mounting position and the transmission shaft is smaller than the distance between the driving position and the transmission shaft. The force arm from the elastic member's action point to the transmission shaft is smaller than the force arm from the driving position to the transmission shaft. According to the mechanical relationship, in the process of the driving member transmitting force to the transmission member, the driving member only needs to apply a small force to the driving position to drive the transmission member to rotate. Under the action of the large force of the elastic member, the latch tongue can be completely inserted into the latching structure of the pot cover, thereby ensuring the gap between the pot cover and the pot body. At the same time, the transmission member can be rotated with a small force, thereby achieving the purpose of labor-saving lid opening. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] like Figures 1 to 4 As shown, a cooking utensil comprises a pot body 2 and a pot cover 1 rotatably connected to the pot body 2, and also comprises a lid opening assembly 3 arranged on the pot body 2, the lid opening assembly 3 comprises an operation button 31, a fixed bracket 32, a driving member 33 and a transmission member 34, the driving member 33 and the transmission member 34 are both rotatably connected to the fixed bracket 32, the fixed bracket 32 ​​is fixedly connected to the pot body 2, and the operation button 31 acts on the driving member 33 so that the driving member 33 drives the transmission member 34 to move and lock or unlock with the pot cover 1.

[0046] It can be understood that one end of the pot cover 1 is rotatably connected to the pot body 2, and the other end can cooperate with the lid opening assembly 3, so as to lock the end with the pot body 2 to achieve closing the lid. When opening the lid, the user presses the operation button 31 to unlock the lid opening assembly 3 and the pot cover 1, and the pot cover 1 flips upward and opens under the action of the torsion spring at the connection end to complete the lid opening.

[0047] In the utility model, the driving member 33 and the transmission member 34 are fixed to the fixed bracket 32, and the fixing of the fixed bracket 32 ​​to the pot body 2 realizes the indirect fixing of the driving member 33 and the transmission member 34 to the pot body 2. Therefore, during assembly, it is not necessary to fix each component to the pot body 2 in sequence, but first assemble the driving member 33, the transmission member 34 and the elastic member 35 to the fixed bracket 32, so that each component forms an integral assembly, and then the assembly is fixed to the pot body 2 as a whole, thereby realizing the rapid assembly of the lid opening assembly 3 and the pot body 2, which not only reduces the difficulty of assembly, but also greatly shortens the assembly time and improves the assembly efficiency. On the other hand, by installing the driving member 33 and the transmission member 34 and other components through a separate fixed bracket 32, the overall strength of the lid opening assembly 3 is improved, the stability of the movement of each component is improved, and the reliability of the lid opening function is improved.

[0048] Specifically, the driving member 33 and the transmission member 34 are both rotatably connected to the fixed bracket 32, and thus can be regarded as two lever structures. When the user presses the operation button 31, the operation button 31 moves to form a thrust on one end of the driving member 33, causing the driving member 33 to swing, and then the other end of the driving member 33 drives the transmission member 34, causing the transmission member 34 to swing, thereby completing the unlocking of the pot cover 1. Figure 5 , Figure 6 As shown, the force arm of one end of the transmission member 34 cooperating with the driving member 33 is longer than the end cooperating with the pot cover 1, so the thrust of the driving member 33 acting on the transmission member 34 can be amplified, so that the transmission member 34 can respond more promptly, and the force arm is increased, which makes it easier for the user to press the operation button 31, thereby improving the user experience.

[0049] As a preferred embodiment of the present invention, Figure 8 As shown, the driving member 33 includes a driving shaft 331 that cooperates with the fixed bracket 32, a driving end 332 located on one side of the driving shaft 331, and a trigger end 333 located on the other side of the driving shaft 331, the driving end 332 is used to cooperate with the operation button 31, the trigger end 333 is used to drive the transmission member 34, and the distance between the driving end 332 and the driving shaft 331 is smaller than the distance between the trigger end 333 and the driving shaft 331.

[0050] In the present embodiment, the driving shaft 331 is closer to the driving end 332, so that the force arm between the driving end 332 and the driving shaft 331 is shorter, and the force arm between the trigger end 333 and the driving shaft 331 is longer. When the driving end 332 is pressed, the lifting space of the trigger end 333 can be guaranteed, thereby improving the triggering effect of the driving member 33 on the transmission member 34, and enabling the transmission member 34 to respond more quickly to the movement of the operating button 31, thereby improving the sensitivity of opening the cover.

[0051] In this embodiment, the design of the force arms at both ends of the driving member 33 makes the space occupied by the cover opening component 3 smaller, and the assembly of the driving member 33 and the transmission member 34 is more compact. Moreover, although the force arm of the driving end 332 is smaller than the force arm of the trigger end 333, the force-saving lever formed by the transmission member 34 can also achieve the effect of saving more effort when the user presses the operation button 31.

[0052] Of course, the force arm of the driving end 332 of the driving member 33 can also be set to be greater than the force arm of the triggering end 333, so that the thrust applied by the user to the operating button 31 is successively transmitted through the two effort-saving levers and acts more greatly on the end of the transmission member 34 that cooperates with the pot cover 1.

[0053] Specifically, Figures 9 to 11 As shown, the transmission member 34 includes a transmission shaft 341 matched with the fixed bracket 32, a transmission end 343 located on one side of the transmission shaft 341, and an action end 342 located on the other side of the transmission shaft 341, and the action end 342 is provided with a tongue 344 for matching with the pot cover 1. The driving shaft 331 is located below the driving shaft 341, and the fixed bracket 32 ​​is provided with a first shaft hole 322 matched with the driving shaft 331, and a second shaft hole 323 matched with the driving shaft 341. The driving end 332 is located on the upper side of the driving shaft 331 and is provided with a driving plane, the trigger end 333 is located on the lower side of the driving shaft 331 and is provided with a trigger plane, the transmission end 343 is located on the lower side of the transmission shaft 341 and is used to match with the trigger end 333, and the action end 342 is located on the upper side of the driving shaft 341, and is used to lock or unlock with the pot cover 1 through the tongue 344.

[0054] When the user presses the operating button 31 horizontally inward, the operating button 31 contacts the driving plane on the upper side of the driving member 33, and causes the driving member 33 to rotate as a whole around the driving shaft 331. At the same time, the trigger end 333 on the lower side swings outward, contacts the transmission end 343 of the transmission member 34 through the trigger plane, and pushes the transmission end 343 to swing outward around the transmission shaft 341, so that the tongue 344 of the upper action end 342 of the transmission member 34 swings inward, thereby loosening from the snap-fit ​​structure 13 on the pot cover 1, thereby unlocking the pot cover 1.

[0055] Among them, at least part of the driving end 332 extends to the outside of the pot body 2, so that the driving plane protrudes from the trigger plane of the trigger end 333. On the one hand, the driving end 332 is closer to the operation button 31, and is more easily triggered by the operation button 31, reducing the idle travel of the trigger button and improving the sensitivity of the action response. On the other hand, the space between the trigger end 333 and the transmission end 343 of the transmission member 34 is increased, leaving enough movement space for the trigger end 333, and at the same time, the overall volume of the driving member 33 and the transmission member 34 after assembly can be reduced, saving space in the pot body 2.

[0056] In a preferred embodiment, Figure 5 , Figure 6 , Figures 9 to 11 As shown, the transmission member 34 includes a transmission shaft 341 that cooperates with the fixed bracket 32, a transmission end 343 located on one side of the transmission shaft 341, and an action end 342 located on the other side of the transmission shaft 341, the transmission end 343 is provided with a contact arc surface 346 for cooperating with the driving member 33, and the action end 342 is provided with a tongue 344 for cooperating with the pot cover 1.

[0057] When one end of the driving member 33 is pushed by the operating button 31 and swings, it triggers the transmission end 343 of the transmission member 34, pushing the transmission member 34 to swing around the transmission shaft 341, and the driving member 33 contacts the contact arc surface 346, so that the contact between the two is line contact (the arc and the straight line are point contact, because the trigger end 333 and the transmission end 343 are both three-dimensional structures with a certain width, it is a line contact between the arc surface and the plane), thereby reducing the contact area between the two, reducing the friction between the two, making the movement of the transmission member 34 smoother, and reducing the sticking feeling generated during the movement of the transmission member 34, thereby improving the operating feel.

[0058] Specifically, Figure 2 , Figure 4 As shown, the pot cover 1 includes a surface cover 11 and an inner cover 12. A snap-fit ​​structure 13 is provided on the inner side of the side wall of the surface cover 11. The snap-fit ​​structure 13 can be a snap-fit ​​groove, a snap interface or a snap hook, etc. The locking is completed by hooking the laterally extending snap tongue 344 with the snap-fit ​​structure 13. When the transmission member 34 rotates, the snap tongue 344 moves to loosen the snap-fit ​​structure 13 and form an avoidance, so that the pot cover 1 loses its restriction and is unlocked.

[0059] Preferably, if Fig. 9 , Fig.10 As shown, matching ribs are provided on the left and right sides of the transmission member 34, the transmission shaft 341 is provided on the outside of the matching ribs, and at least one reinforcing rib 3411 is provided on the inside of the matching ribs to improve the strength of the matching ribs and the transmission shaft 341, reduce the risk of deformation or damage, and ensure the normal rotation of the transmission shaft 341.

[0060] Preferably, the transmission shaft 341 is arranged directly below the surface of the tongue 344. If it is offset from the tongue 344, it will form a certain angle with the tongue 344. After the tongue 344 is subjected to force, the transmission member 34 will move toward the inside of the pot body 2, increasing the risk of detachment from the pot cover 1.

[0061] Furthermore, if Fig.10 As shown, the contact arc surface 346 is provided with a plurality of contact ribs 347 at intervals along the width direction of the transmission member 34 , and the contact ribs 347 are used to contact the driving member 33 .

[0062] By providing the contact rib 347 on the contact arc surface 346, the contact area between the transmission end 343 and the driving member 33 is further reduced, the friction resistance is reduced, the motion transmission between the two is smoother, and the feeling of jamming is reduced. Fig.10 As shown, the contact ribs 347 are arranged along the circumference of the contact arc surface 346 , and there are multiple contact ribs 347 that are spaced apart along the width direction of the transmission end 343 .

[0063] Preferably, if Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the pot cover 1 includes a surface cover 11 and an inner cover 12 located on the inner side of the surface cover 11, the action end 342 is located between the surface cover 11 and the inner cover 12, and a stop protrusion 345 is provided on the side of the action end 342 facing the inner cover 12. When the inner cover 12 is screwed together with the pot body 2, the inner cover 12 cooperates with the stop protrusion 345 to limit the swing of the transmission member 34.

[0064] When the pot cover 1 is screwed together with the pot body 2, the inner cover 12 and the stop protrusion 345 form a stop cooperation, and the transmission member 34 cannot swing due to the stop of the inner cover 12, thereby limiting the transmission member 34 to a state where the latch 344 is locked with the pot cover 1. In the pressure cooking device, after the pot cover 1 is screwed together with the pot body 2, the user cannot open the cover by pressing the operation button 31, ensuring cooking in a safe environment.

[0065] It should be noted that the state in which the pot cover 1 and the pot body 2 are screwed together is a state existing in pressure cooking appliances. For pressure cooking appliances (such as pressure cookers), after the pot cover 1 is covered with the pot body 2, the pot cover 1 needs to be rotated so that the cover teeth on the pot cover 1 and the pot teeth on the pot body 2 are aligned and engaged with each other, and the pot cover 1 is locked on the pot body 2, so that during the pressure cooking process, the pot cover 1 will not be bounced open under the action of air pressure, ensuring safe cooking. In this state, the inner side of the self-acting end 342 of the inner cover 12 is stopped by the stop protrusion 345, thereby limiting the rotation of the transmission member 34. At this time, even if the user presses the operation button 31, the transmission member 34 cannot rotate, and the lid cannot be opened. Only when the pressure cooking is finished, or the pressure in the pot is reduced to a level close to the external air pressure, the user rotates the pot cover 1 to unlock the cover teeth and the pot teeth, and the transmission member 34 loses the limit, can the lid be opened by the operation button 31.

[0066] Of course, the type of cooking utensil in the present invention is not limited to a pressure cooking utensil, and it may also be a normal pressure cooking utensil, such as a conventional rice cooker, etc., which is not limited here.

[0067] As a preferred embodiment of the present invention, Figure 5 , Figure 6 , Fig.10 As shown, the driving member 33 has a driving end 332 for cooperating with the operating button 31, and the transmission member 34 is provided with an avoidance opening 349 for the operating button 31 to pass through. The driving end 332 is arranged corresponding to the avoidance opening 349, and the edge of the avoidance opening 349 is provided with a limiting rib 3491 protruding toward the driving end 332.

[0068] The operation button 31 has a trigger portion corresponding to the avoidance opening 349. When the user presses the operation button 31, the trigger portion passes through the avoidance opening 349 to trigger the driving end 332 of the driving member 33. The limiting rib 3491 can limit the left and right movement of the driving member 33, ensuring that the driving member 33 moves on a preset path and preventing interference with other structures that may cause abnormal movement of the driving member 33.

[0069] Preferably, if Figure 1 , Figure 7 As shown, the pot body 2 includes a cover shell 21, a water collecting ring 22 placed above the cover shell 21, and a base 23 placed below the cover shell 21. The fixed bracket 32 ​​is provided with a first fixed portion 324 and a second fixed portion 325. The first fixed portion 324 is used to be fixedly connected to the water collecting ring 22, and the second fixed portion 325 is used to be fixedly connected to the base 23.

[0070] The upper end of the fixed bracket 32 ​​is fixed to the water collecting ring 22, and the lower end is fixed to the base 23, so that both ends of the fixed bracket 32 ​​are fixed, and the connection stability of the fixed bracket 32 ​​and the opening cover assembly 3 is improved. Figure 7As shown, the first fixing portion 324 is provided with a screw hole, and the second fixing portion 325 is provided with a screw column, which is respectively fastened to the water collecting ring 22 and the base 23 by means of screws. Of course, the connection of the fixing bracket 32 ​​can also be achieved by other means, such as snap connection, etc., which is not limited here.

[0071] Furthermore, if Figure 7 As shown, the second fixing portion 325 includes a fixing hole, and the cooking utensil also includes a fastener, which passes through the fixing hole to fasten the fixing bracket 32 ​​to the base 23, and one of the fixing bracket 32 ​​and the base 23 is provided with a limiting protrusion 326, and the other of the two is provided with a limiting groove that is plugged into and cooperates with the limiting protrusion 326.

[0072] Before fastening the second fixing portion 325 to the base 23, the limiting protrusion 326 and the limiting groove are first plugged in to form a rotation stop for the fixing bracket 32 ​​to prevent the fixing bracket 32 ​​from rotating during the tightening of the fasteners, thereby reducing the difficulty of assembly. Figure 7 As shown, the fixed bracket 32 ​​is provided with a limiting protrusion 326, and the base 23 is provided with a limiting groove. Of course, the limiting groove can also be provided on the fixed bracket 32, and the limiting protrusion 326 can be provided on the base 23, which is not limited here.

[0073] As a preferred embodiment, Figure 5 , Figure 6 As shown, the transmission member 34 includes a transmission shaft 341, and the cover opening assembly 3 also includes an elastic member 35. The transmission member 34 is provided with a mounting position located on one side of the transmission shaft 341, and a driving position located on the other side of the transmission shaft 341. The mounting position is used to install the elastic member 35, and the driving position is used to cooperate with the driving member 33 for transmission. The distance between the mounting position and the transmission shaft 341 is smaller than the distance between the driving position and the transmission shaft 341.

[0074] The force arm from the action point of the elastic member 35 to the transmission shaft 341 is smaller than the force arm from the driving position to the transmission shaft 341. According to the mechanical relationship, in the process of the driving member 33 transmitting force to the transmission member 34, the driving member 33 only needs to apply a smaller force to the driving position to drive the transmission member 34 to rotate. Under the action of the larger force of the elastic member 35, the latch tongue 344 can be completely inserted into the latching structure 13 of the pot cover 1, ensuring the gap between the pot cover 1 and the pot body 2. At the same time, a smaller force can be used to rotate the transmission member 34, thereby achieving the purpose of saving effort in opening the lid.

[0075] In addition, the elastic member 35 is located on the upper side of the transmission shaft 341, on the same side as the action end 342 of the transmission member 34, so that it is closer to the tongue 344. The closer to the tongue 344, the greater the force of the elastic member 35 on the end of the tongue 344, thereby ensuring the stability of the fit between the tongue 344 and the pot cover 1.

[0076] Preferably, the elastic member 35 is a spring. Of course, it can be other elastic structures such as a silicone block, which is not limited here.

[0077] Preferably, if Figure 5 , Figure 6 As shown, the cover opening assembly 3 also includes an elastic member 35, and one of the transmission member 34 and the fixed bracket 32 ​​is provided with a positioning channel 348 for accommodating the elastic member 35, and the other corresponding positioning channel 348 is provided with a positioning protrusion 321, and the elastic member 35 is sleeved on the positioning protrusion 321.

[0078] The positioning protrusion 321 and the positioning channel 348 cooperate to form a mounting position for mounting the elastic member 35, so that the position of the elastic member 35 is stable. Specifically, the elastic member 35 is placed inside the mounting channel and sleeved on the outer periphery of the positioning protrusion 321. The two cooperate to form a deformation guide for the elastic member 35 to prevent abnormal deformation of the elastic member 35.
