Description

Technical Field

[0001] This application relates to the field of kitchen utensil technology, and more particularly to a clamping device, a pressure cooker lid, and a pressure cooker. Background Technology

[0002] A pressure cooker is a common cooking appliance that primarily increases the heating temperature by increasing the pressure inside the pot, thereby accelerating the heating process. A pressure cooker mainly consists of a pressure lid and a pot body, connected by clamps. These clamps can move relative to the pot body to simultaneously clamp and release the pressure. Only when the clamps are clamped can the pressure cooker withstand high pressure. Sometimes, users may accidentally operate the pressure cooker, causing the clamps to be in an intermediate state between clamping and releasing. In this state, high pressure can build up inside the pot, posing a potential danger. Utility Model Content

[0003] This application provides a clamping device, a pressure cooker lid, and a pressure cooker to prevent the clamp from entering an intermediate state between clamping and unclamping, thereby improving the safety of using the pressure cooker.

[0004] The first aspect of this application provides a clamping device, which includes:

[0005] Support components;

[0006] At least two clamps are slidably connected to the support assembly, and each clamp is driven to enable the clamps to clamp or de-clamp synchronously, wherein one of the clamps is an active clamp.

[0007] An actuating element is pivotally connected to the support assembly, and the actuating element abuts against the active clamp to push the active clamp to slide along the support assembly;

[0008] Of the actuating component and the supporting component, one is provided with an elastic positioning component, and the other is provided with a first positioning groove and a second positioning groove. The exposed part of the elastic positioning component is a spherical surface, and the first positioning groove and the second positioning groove are arranged adjacent to each other.

[0009] When the elastic positioning element is engaged in the first positioning groove, each of the clamps clamps.

[0010] When the elastic positioning element is engaged in the second positioning groove, each of the clamps releases its clamping action.

[0011] The clamping device provided in this application includes a support assembly, at least two clamps, and a lever. The clamps are slidably connected to the support assembly, and each clamp is drive-connected to enable synchronous clamping or unclamping. One of the clamps is an active clamp. The lever is pivotally connected to the support assembly and abuts against the active clamp to push the active clamp to slide along the support assembly, thereby driving the clamps to move synchronously. One of the lever and the support assembly is provided with an elastic positioning element, and the other is provided with a first positioning groove and a second positioning groove. When the elastic positioning element is engaged in the first positioning groove, the clamps clamp, and a reliable connection can be formed between the pressure cooker lid and the pot body. When the elastic positioning element is engaged in the second positioning groove, the clamps unclamp, and the pressure cooker lid can be mounted on or removed from the pot body. The exposed portion of the elastic positioning element is a spherical surface. The first positioning groove and the second positioning groove are set adjacent to each other. Therefore, when the exposed portion of the elastic positioning element abuts between the first positioning groove and the second positioning groove, the larger spherical surface abuts against the very small gap, making it difficult for the elastic positioning element to maintain a stable state. The elastic positioning element will automatically move towards the first positioning groove or the second positioning groove. Therefore, the elastic positioning element can only change abruptly between the state of being engaged in the first positioning groove and the state of being engaged in the second positioning groove. This can prevent the clamp from entering an intermediate state between clamping and unclamping, thus improving the safety of using the pressure cooker.

[0012] Optionally, one of the actuating member and the supporting component is provided with an elastic locking member, and the other is provided with a first locking groove and a second locking groove. The exposed portion of the elastic locking member includes a conical surface, and the first locking groove and the second locking groove are spaced apart. When each of the clamps clamps, the elastic locking member engages in the first locking groove; when each of the clamps releases its clamp, the elastic locking member engages in the second locking groove. On the one hand, this ensures that the clamps can be stably and reliably maintained in the clamped or unclamped state, preventing accidental changes in the clamp's state during use and affecting the safety of the pressure cooker. On the other hand, it allows the elastic locking member to quickly slide into the corresponding positioning groove when the clamps are in position, increasing the stability and reliability of the locking engagement and providing an audible indication of the position being reached due to rapid impact.

[0013] Optionally, the elastic positioning member includes a ball and a first elastic member, the first elastic member abutting against the inner side of the ball to force the ball to protrude outward. Since the ball can roll within the mounting hole, the flexibility of the elastic positioning member's movement is further increased, ensuring that the state of the elastic positioning member abutting between the first positioning groove and the second positioning groove can be disrupted.

[0014] Optionally, the pivot axes of the elastic positioning element and the actuating element are arranged side by side. This allows the distance between the pivot axes of the elastic positioning element and the actuating element to be reasonably set as needed, ensuring both the structural strength of the elastic positioning element itself and improving the compactness of the overall structure.

[0015] Optionally, the elastic positioning element is disposed on the actuating element, and the first positioning groove and the second positioning groove are disposed on the support assembly; the number of elastic positioning elements is two, the two elastic positioning elements are coaxially disposed, and the two elastic positioning elements are respectively exposed on opposite sides of the actuating element. This allows the two sides of the actuating element to be positioned respectively, preventing abnormalities such as torsion of the actuating element from affecting the reliability of the clamp.

[0016] Optionally, the actuating element includes a first extension and a second extension, which are disposed opposite to each other on both sides of the pivot axis of the actuating element. The clamping device further includes a first button and a second button, which are respectively mounted on the support assembly. The first button acts on the first extension to force the actuating element to move the clamp in the direction of clamping. The second button acts on the second extension to force the actuating element to move the clamp in the direction of releasing the clamp. The first and second buttons provide the power for the actuating element to swing. The user can close the lid by pressing the first button and open the lid by pressing the second button, making the opening and closing of the lid easier and improving the user experience of the pressure cooker.

[0017] Optionally, the second button is connected to a pin, which is parallel to the pivot axis of the toggle member. The second extension is provided with a guide groove, and the pin slides along the guide groove to convert the linear sliding of the second button into the swinging motion of the toggle member. The second button and the second extension are always connected, so that the second button is locked together with the toggle member, thereby keeping the second button stably in the raised or lowered state, allowing the user to accurately identify the current state of the pressure cooker lid.

[0018] Optionally, the active clamp has a slot, and the end of the actuating member away from the pivot axis extends into the slot. When the actuating member swings, it abuts against the wall of the slot. On the one hand, the actuating member directly engages with the active clamp, eliminating the need for intermediate connecting parts, which simplifies the overall structure and increases connection strength. On the other hand, the engagement between the actuating member and the active clamp is within the contour of the active clamp, making the overall structure more compact.

[0019] Optionally, the support assembly includes a detachably connected support member and an outer cover. The clamp is slidably connected to the interior of the support member, and the surface of the support member is provided with a through groove. The actuating member is pivotally connected to the outer cover, and the end of the actuating member away from the pivot axis passes through the through groove and abuts against the active clamp. This allows the clamp and the actuating member to move independently in two separate spaces, resulting in a simpler and more reliable overall structure.

[0020] Optionally, a gear is centrally connected to the support assembly, and the clamps are equipped with racks that mesh with the gear. Each clamp and the gear form a rack and pinion transmission mechanism, realizing the transmission connection between the clamps. The structure is simple and compact, and the operation is precise and efficient.

[0021] A second aspect of this application provides a pressure cooker lid, comprising a lid body and any of the clamping devices provided in this application, the clamping device being connected to the lid body. When the exposed portion of the elastic positioning member abuts between the first positioning groove and the second positioning groove, the larger spherical surface abuts against the very small gap, making it difficult for the elastic positioning member to maintain a stable state. The elastic positioning member will automatically move towards the first positioning groove or the second positioning groove. Therefore, the elastic positioning member can only abruptly change between the state of being engaged in the first positioning groove and the state of being engaged in the second positioning groove, thereby preventing the clamp from entering an intermediate state between clamping and unclamping, improving the safety of using the pressure cooker.

[0022] A third aspect of this application provides a pressure cooker, comprising a pot body and any of the pressure cooker lids provided in this application. When the pressure cooker lid is closed on the pot body, the clamping device can simultaneously clamp the pressure cooker lid and the pot body. When the exposed portion of the elastic positioning member abuts between the first positioning groove and the second positioning groove, the large spherical surface abuts against a very small gap, making it difficult for the elastic positioning member to maintain a stable state. The elastic positioning member will automatically move towards the first positioning groove or the second positioning groove. Therefore, the elastic positioning member can only abruptly change between the state of being engaged in the first positioning groove and the state of being engaged in the second positioning groove, thereby preventing the clamp from entering an intermediate state between clamping and unclamping, and improving the safety of using the pressure cooker.

[0064] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0065] 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.

[0066] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0067] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0068] like Figures 1-3 As shown, this application embodiment provides a pressure cooker lid that can be fitted onto a pot body 30, forming a pressure cooker together with the pot body 30. The pressure cooker lid includes a detachably connected lid body 20 and a clamping device 10. For example, the clamping device 10 can be connected to the lid body 20 by screws or clips. When the pressure cooker lid is fitted onto the pot body 30, the clamping device 10 can simultaneously clamp the pressure cooker lid and the pot body 30, thereby achieving a reliable connection between the pressure cooker lid and the pot body 30. The lid body 20 is provided with a sealing ring, a pressure limiting valve, and a check valve. The sealing ring is used to form a seal between the pressure cooker lid and the pot body 30, the pressure limiting valve is used to limit the maximum pressure inside the pot, and the check valve is used to form a sealed state or a pressure relief state.

[0069] like Figures 2-6 As shown, the clamping device 10 provided in this embodiment includes a support assembly 1 and at least two clamps 2. The support assembly 1 is used to connect to the lid 20, that is, the support assembly 1 forms the external shape of the clamping device 10. All other components of the clamping device 10 are installed on the support assembly 1, so that the clamping device 10 can be used as a whole, making it convenient for the pressure cooker lid to be disassembled, cleaned and maintained as needed. The clamps 2 are slidably connected to the support assembly 1, and each clamp 2 is drive-connected so that each clamp 2 can clamp or de-clamp synchronously. That is, as long as any one clamp 2 is operated to slide, it can drive the synchronous movement of all clamps 2, so that each clamp 2 moves synchronously towards the axis of the lid 20 and clamps, or moves synchronously away from the axis of the lid 20 and de-clamps.

[0070] Furthermore, one of the clamps 2 is an active clamp 2a, and the clamping device 10 also includes an actuating element 3, which is disposed above the active clamp 2a. The actuating element 3 is pivotally connected to the support assembly 1, that is, one end of the actuating element 3 is connected to the support assembly 1 through a pivot shaft 35, and the actuating element 3 can reciprocate around the pivot shaft 35. The actuating element 3 abuts against the active clamp 2a, that is, the other end of the actuating element 3 can apply a radial force along the cover 20 to the active clamp 2a to push the active clamp 2a to slide along the support assembly 1, thereby driving all the clamps 2 to move synchronously through the active clamp 2a.

[0071] Furthermore, of the actuating member 3 and the supporting assembly 1, one is provided with an elastic positioning member 31, and the other is provided with a first positioning groove 11 and a second positioning groove 12. The first positioning groove 11 and the second positioning groove 12 are arranged along the swing direction of the actuating member 3. As the actuating member 3 swings, the elastic positioning member 31 can be engaged in the first positioning groove 11 or the second positioning groove 12. When the elastic positioning member 31 is engaged in the first positioning groove 11 (refer to...), Figure 2 Each clamp 2 clamps securely, at which point a reliable connection is formed between the pressure cooker lid and the pot body 30; when the elastic positioning element 31 engages with the second positioning groove 12 (refer to...) Figure 3 When each clamp 2 is released, the pressure cooker lid can be mounted on or removed from the pot body 30.

[0072] Furthermore, the exposed portion of the elastic positioning member 31 is a spherical surface, meaning that the exposed portion of the elastic positioning member 31 is curved as a whole, and the degree of curvature remains consistent at any position of the exposed portion. The first positioning groove 11 and the second positioning groove 12 are arranged adjacent to each other, that is, the opening of the first positioning groove 11 is tangent to the opening of the second positioning groove 12 or has a very small gap. Therefore, when the exposed portion of the elastic positioning member 31 abuts between the first positioning groove 11 and the second positioning groove 12, the larger spherical surface abuts against the very small gap, making it difficult for the elastic positioning member 31 to maintain a stable state. The elastic positioning member 31 will automatically move towards the first positioning groove 11 or the second positioning groove 12. Therefore, the elastic positioning member 31 can only change abruptly between the state of being engaged in the first positioning groove 11 and the state of being engaged in the second positioning groove 12, thereby preventing the clamp 2 from entering an intermediate state between clamping and unclamping, and improving the safety of using the pressure cooker.

[0073] Furthermore, of the actuating member 3 and the supporting assembly 1, one is provided with an elastic locking member 32, and the other is provided with a first locking groove 13 and a second locking groove 14. The first locking groove 13 and the second locking groove 14 are arranged along the rotation direction of the actuating member 3. As the actuating member 3 swings, the elastic locking member 32 can engage with the first locking groove 13 or the second locking groove 14. When each clamp 2 achieves clamping (refer to...), Figure 2 When the elastic locking element 32 engages with the first locking groove 13, the clamp 2 can be stably and reliably held in the clamping state; when each clamp 2 releases its clamping action (see reference...), Figure 3 The elastic locking element 32 engages with the second locking groove 14, thereby enabling the clamp 2 to be stably and reliably held in the unclamped state.

[0074] Furthermore, the exposed portion of the elastic locking member 32 includes a tapered surface; that is, at least a section of the exposed portion of the elastic locking member 32 is a tapered surface, so that the elastic locking member 32 has a smaller exposed end face. The first locking groove 13 and the second locking groove 14 are spaced apart, that is, there is a large gap between the opening of the first locking groove 13 and the opening of the second locking groove 14. As a result, when the clamp 2 moves into position (i.e., when clamping or unclamping), the elastic locking member 32 quickly slides into the corresponding positioning groove, which not only increases the stability and reliability of the locking engagement, but also provides an audible indication of the movement being in place due to rapid impact.

[0075] Specifically, when the swinging member is in the middle of its stroke, the elastic positioning member 31 activates, disrupting the balance of this state and causing it to abruptly shift to either the state of being engaged in the first positioning groove 11 or the state of being engaged in the second positioning groove 12. This prevents the clamp 2 from entering an intermediate state between clamping and unclamping. When the swinging member is at the end of its stroke, the elastic locking member 32 activates, quickly engaging in the first locking groove 13 or the second locking groove 14. This locks the clamp 2 in either the clamping or unclamping state and provides an audible prompt.

[0076] Furthermore, the actuating element 3 includes a first extension 33 and a second extension 34, which are disposed opposite to each other on both sides of the pivot shaft 35 of the actuating element 3. The clamping device 10 also includes a first button 4 and a second button 5, which are respectively mounted on the support assembly 1. The first button 4 acts on the first extension 33 to force the actuating element 3 to move the clamp 2 in the direction of clamping; the second button 5 acts on the second extension 34 to force the actuating element 3 to move the clamp 2 in the direction of releasing the clamp. Thus, the first button 4 and the second button 5 provide the power for the actuating element 3 to swing. The user can close the lid by pressing the first button 4 and open the lid by pressing the second button 5, making the opening and closing of the lid easier and improving the user experience of the pressure cooker.

[0077] Furthermore, the first button 4 abuts against the surface of the first extension 33, and an elastic reset member 41 is provided between the first button 4 and the support assembly 1. When the user presses the first button 4, the first button 4 abuts against the surface of the first extension 33, thereby pushing the toggle member 3 to swing and realize the closing operation; when the closing operation is in place, when the user releases the first button 4, the first button 4 can automatically spring back to its original position, and the first button 4 and the first extension 33 separate from each other, so that the user can press the first button 4 again.

[0078] Furthermore, the second button 5 is connected to a pin 51, which is parallel to the pivot axis 35 of the toggle member 3. The second extension 34 is provided with a guide groove 341. The pin 51 is inserted into the guide groove 341 and slides along the guide groove 341 to convert the linear sliding of the button into the swinging motion of the toggle member 3. The second button 5 and the second extension 34 are always connected, so that the second button 5 is locked together with the toggle member 3, thereby keeping the second button 5 stably in the raised or lowered state, making it convenient for the user to accurately identify the current state of the pressure cooker lid. Specifically, when the second button 5 is in the raised state, the pressure cooker lid is in the closed state, and the user can press the second button 5 to open the lid; when the second button 5 is in the lowered state, the pressure cooker lid is in the open state, and the user can press the first button 4 to close the lid.

[0079] Furthermore, a gear 15 is centrally connected to the support assembly 1, and the clamp 2 is equipped with a rack 22, which meshes with the gear 15. Each clamp 2 and the gear 15 form a gear and rack 22 transmission mechanism, realizing the transmission connection between each clamp 2. The structure is simple and compact, and the operation is precise and efficient.

[0080] Furthermore, the active clamp 2a may be provided with a slot 21, and the end of the actuating member 3 away from the pivot shaft 35 extends into the slot 21. When the actuating member 3 swings, it abuts against the wall of the slot 21, thereby pushing the active clamp 2a to slide along the support assembly 1. On the one hand, the actuating member 3 directly engages with the active clamp 2a, eliminating the need for intermediate connecting parts, which simplifies the overall structure and increases the connection strength; on the other hand, the engagement between the actuating member 3 and the active clamp 2a is within the contour of the active clamp 2a, making the overall structure more compact.

[0081] like Figure 6 and Figure 7 As shown, the elastic positioning element 31 and the pivot axis 35 of the actuating element 3 are arranged side by side. That is, the elastic positioning element 31 is located on one side of the pivot axis 35 of the actuating element 3, and the extension and retraction direction of the elastic positioning element 31 is parallel to the pivot axis 35 of the actuating element 3. This allows the distance between the elastic positioning element 31 and the pivot axis 35 of the actuating element 3 to be reasonably set as needed, ensuring both the structural strength of the elastic positioning element 31 and improving the compactness of the overall structure. Specifically, when the elastic positioning element 31 is too close to the pivot axis 35 of the actuating element 3, the movement path of the elastic positioning element 31 is too short, resulting in the cross-section of the first positioning groove 11 and the second positioning groove 12 being too small. Correspondingly, the diameter of the elastic positioning element 31 is too small, resulting in insufficient strength. When the elastic positioning element 31 is too far away from the pivot axis 35 of the actuating element 3, the movement path of the elastic positioning element 31 is too large, the cross-section of the first positioning groove 11 and the second positioning groove 12 is too large, and correspondingly, the diameter of the elastic positioning element 31 is too large, resulting in an excessively large overall volume.

[0082] Furthermore, the elastic positioning element 31 is disposed on the actuating element 3, and the first positioning groove 11 and the second positioning groove 12 are disposed on the support assembly 1. This not only reduces the volume of the actuating element 3, but also makes full use of the large surface area of ​​the support assembly 1, making the space utilization more reasonable and improving the overall structural compactness.

[0083] Furthermore, there are two elastic positioning elements 31, which are coaxially arranged and exposed on opposite sides of the actuating element 3. This ensures that both sides of the actuating element 3 are positioned, preventing abnormalities such as torsion from affecting the reliability of the clamp 2.

[0084] Furthermore, the elastic positioning member 31 includes a ball 311 and a first elastic member 312, which are accommodated within the first mounting hole. The first elastic member 312 abuts against the inner side of the ball 311 to force the ball 311 to protrude outward; that is, a portion of the ball 311 forms the exposed portion of the elastic member. Because the ball 311 can roll within the mounting hole, the flexibility of the elastic positioning member 31's movement is further increased, ensuring that the state of the elastic positioning member 31 abutting against the first positioning groove 11 and the second positioning groove 12 can be disrupted.

[0085] Furthermore, the elastic locking member 32 and the pivot axis 35 of the actuating member 3 are arranged side by side. That is, the elastic locking member 32 is disposed on one side of the pivot axis 35 of the actuating member 3, and the extension and retraction direction of the elastic locking member 32 is parallel to the pivot axis 35 of the actuating member 3. This makes the gap surface between the first locking groove 13 and the second locking groove 14 a plane, and the exposed part of the elastic locking member 32 moves along the plane, making the overall structure simpler.

[0086] Furthermore, the resilient locking member 32 includes a locking pin 321 and a second resilient member 322, which are accommodated within the second mounting hole. The second resilient member 322 abuts against the inner end of the locking pin 321, forcing the locking pin 321 to protrude outward. That is, the exposed portion of the locking pin 321 includes a tapered surface, and the small end of the tapered surface can be further provided with a spherical surface. Since the locking pin 321 itself is a rigid member, it can ensure that a rigid fit is formed between the resilient locking member 32 and the first locking groove 13, and between the resilient locking member 32 and the second locking groove 14, ensuring the stability and reliability of the locked state.

[0087] like Figure 8As shown, the support assembly 1 includes a detachably connected support member 1a and an outer cover 1b. The clamp 2 is slidably connected to the interior of the support member 1a; that is, a portion of the clamp 2 is inserted into the interior of the support member 1a and slides along it. The actuating member 3 is pivotally connected to the outer cover 1b, with one end of the actuating member 3 away from the pivot axis 35 passing through a through groove 16 on the surface of the support member 1a and abutting against the active clamp 2a. The clamp 2 and the support member 1a form a single unit, enabling transmission between the clamps 2; the actuating member 3 and the outer cover 1b form a single unit, enabling connection and cooperation between the actuating member 3 and other components (e.g., the elastic positioning member 31, the elastic locking member 32, the first button 4, and the second button 5). This allows the clamp 2 and the actuating member 3 to move independently in two separate spaces, resulting in a simpler and more reliable overall structure.

[0088] In addition, this application embodiment also provides a pressure cooker, which includes a pot body 30 and any of the pressure cooker lids provided in this application. When the pressure cooker lid is closed on the pot body 30, the clamping device 10 can simultaneously clamp the pressure cooker lid and the pot body 30.

[0089] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
