Description

Technical Field

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

[0002] A pressure cooker is a common cooking appliance. Its main function is to increase the heating temperature by increasing the pressure inside the pot, thereby increasing the heating speed. A pressure cooker mainly consists of a pressure lid and a pot body. The lid and pot body are connected by clamps, which can move relative to the pot body to simultaneously clamp or release the clamps. 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 fail to clamp properly. In this case, high pressure can form inside the pot, which can be dangerous. Utility Model Content

[0003] This application provides a pressure cooker lid and a pressure cooker, so that the pressure cooker lid can automatically form a clamping state, thereby improving the safety of using the pressure cooker.

[0004] A first aspect of this application provides a pressure cooker lid, the pressure cooker lid comprising a detachably connected lid body and a clamping device, the clamping device comprising:

[0005] Support member, the support member being used to connect the cover body;

[0006] Two clamps are arranged opposite each other on both sides of the axis of the cover. The clamps are slidably connected to the support to clamp or unclamp. The clamps are provided with guide pins.

[0007] An operating component includes a connecting shaft. The operating component is flipped and connected to the support component via the connecting shaft. The outer periphery of the connecting shaft is provided with a spiral first guide groove. The first guide groove is provided in a one-to-one correspondence with the guide pin. The guide pin slides relative to the first guide groove to convert the flipping motion of the operating component into the radial sliding of the clamp.

[0008] A first elastic element connects the two clamps to force the clamps to clamp.

[0009] The pressure cooker lid provided in this application includes a detachably connected lid body and a clamping device. The clamping device includes a support member, two clamps, an operating member, and a first elastic member. The support member is used to connect to the lid body. The clamps are arranged opposite to each other on both sides of the lid body's axis and are slidably connected to the support member to clamp or release the clamp. The clamps are provided with guide pins. The operating member includes a connecting shaft, and the operating member is flipped and connected to the support member through the connecting shaft. The outer circumference of the connecting shaft is provided with a spiral first guide groove. The first guide groove is arranged one-to-one with the guide pin, and the guide pin slides relative to each other along the first guide groove to convert the flipping motion of the operating member into the radial sliding motion of the clamps. The user only needs to apply external force to the operating member. The flipping motion of the operating component drives the clamps to slide radially along the lid, allowing the clamps to tighten or loosen, thus simplifying the opening and closing of the pressure cooker lid. Furthermore, the sliding engagement of the guide pin with the first guide groove converts the flipping motion of the operating component into the radial sliding motion of the clamps, making the clamp movement smoother and preventing collisions or impacts caused by violent clamp movements. The first elastic element connects the two clamps, forcing them to tighten. In other words, under the traction of the first elastic element, the two clamps can automatically move towards the axis of the lid, thus automatically clamping the pressure cooker and improving its safety during use.

[0010] Optionally, the connecting shaft includes a first shaft segment and a second shaft segment coaxially arranged. There are two first shaft segments, positioned opposite each other at both ends of the second shaft segment. The first shaft segment is rotatably connected to the support member. The outer diameter of the second shaft segment is larger than the outer diameter of the first shaft segment. The first guide groove is disposed on the outer periphery of the second shaft segment. By placing the first guide groove on the second shaft segment with a larger diameter, the contact stress between the guide pin and the first guide groove can be reduced, decreasing the possibility of wear, deformation, or other abnormalities in the guide pin or the first guide groove, effectively extending the service life of the pressure cooker lid.

[0011] Optionally, the first shaft segment is cylindrical, so that the first shaft segment can achieve a large load-bearing capacity with a small diameter, ensuring the stability and reliability of the flipping movement between the operating component and the support component; the cross-section of the second shaft segment is fan-shaped, which can reduce the material of the second shaft segment as much as possible while ensuring the strength of the second shaft segment, reducing the overall weight of the connecting shaft, and also avoid the second shaft segment with a large diameter occupying too much space, making the overall structure of the pressure cooker lid more compact.

[0012] Optionally, a second elastic element, which is a torsion spring, is installed on the inner arc side of the second shaft segment to force the operating member to move in the direction of clamping along with the clamp. When the user releases the operating member in the unclamped state, the operating member automatically rotates in the opposite direction under the rebound force of the second elastic element, thereby reducing or eliminating the resistance of the operating member to the clamp, making it easier for the clamp to move in the direction of clamping, preventing the operating member or clamp from jamming or locking, ensuring that the clamp can automatically move to the clamping state, and further improving the safety of using the pressure cooker.

[0013] Optionally, a connecting post is provided on the inner arc side of the second shaft segment, and the connecting post is provided one-to-one with the first shaft segment. The connecting post is detachably connected to the end face of the first shaft segment. Two limiting flanges are provided at intervals on the outer periphery of the connecting post, and the second elastic element is sleeved on the connecting post, with the second elastic element located between the two limiting flanges. On the one hand, it can avoid the narrow operating space of the connecting shaft, so that the second elastic element and the connecting post can be assembled into a whole in the disassembled state, and then the whole can be connected to the first shaft segment, making the assembly operation of the second elastic element more convenient. On the other hand, the two limiting flanges form an axial limit on the second elastic element, which can prevent the second elastic element from moving or shifting axially during use, thus preventing unnecessary wear between the second elastic element and components such as the connecting shaft.

[0014] Optionally, the second shaft segment includes two opposing first annular segments, with the first guide groove disposed on the outer periphery of the first annular segments; the opposing side of the two first annular segments is a first end face, which is perpendicular to the axis of the connecting shaft, so that an approximately triangular support area is formed between the wall of the first guide groove and the first end face. When the user forcibly opens the pressure cooker under abnormal circumstances, as the user flips the operating parts, the clamps cannot move outward to release the clamping, causing the pressure of the guide pin on the wall of the first guide groove to gradually increase. By setting an approximately triangular support area, the support strength can also gradually increase, thereby preventing the wall of the first guide groove from being subjected to excessive force and causing deformation or cracking.

[0015] Optionally, the first annular segment is connected to the first shaft segment, and the opposite sides of the two first annular segments form the second end face; the second end face is perpendicular to the axis of the connecting shaft, and the second end face is located within the length range of the first shaft segment, and the inner diameter of the first annular segment is smaller than the outer diameter of the first shaft segment. By providing an axial overlapping area and a radial overlapping area between the first annular segment and the first shaft segment, the overall structural strength of the connecting shaft can be guaranteed, preventing breakage or other damage between the first annular segment and the first shaft segment.

[0016] Optionally, the second shaft segment includes a second annular segment disposed between two first annular segments. The inner diameter of the second annular segment is larger than the inner diameter of the first annular segments, and the outer diameter of the second annular segment is smaller than the outer diameter of the first annular segments. On the one hand, connecting the two first annular segments with the second annular segment reduces the bending and deformation of the first annular segments, ensuring synchronous movement of the two first annular segments, thereby ensuring synchronous movement of the two clamps. On the other hand, since the second annular segment experiences less force, using a thinner second annular segment can save materials and reduce the overall weight of the pressure cooker lid.

[0017] Optionally, the connecting shaft has a second guide groove on its outer periphery, which is located at one end of the first guide groove near the axis of the lid. The second guide groove communicates with the first guide groove and extends circumferentially away from the first guide groove. When the guide pin moves to the end of the first guide groove near the axis of the lid, the clamp clamps. At this time, the operating member can be further rotated to allow the guide pin to slide into the second guide groove. The second guide groove provides axial support to the guide pin, ensuring that the clamp remains stably in the clamping position and preventing the clamp position from changing during use, which could affect the safety of the pressure cooker.

[0018] Optionally, the operating component further includes a grip portion, which forms a closed ring with the connecting shaft. This not only allows the connecting shaft and the grip portion to reinforce each other, preventing breakage or other damage to the operating component, but also improves the stability and comfort of the user's grip on the operating component.

[0019] The second aspect of this application provides a pressure cooker, comprising a pot body and any of the pressure cooker lids provided in this application, wherein the pressure cooker lid is fitted onto the pot body. The user only needs to apply external force to the operating component to cause it to rotate, which drives the clamps to slide radially along the lid body, thus clamping or releasing the clamps. This makes opening and closing the pressure cooker lid easier. Furthermore, by sliding the guide pin with the first guide groove, the rotational movement of the operating component is converted into the radial sliding of the clamps, making the movement of the clamps smoother and preventing collisions or impacts caused by violent clamp movements. Under the traction of the first elastic element, the two clamps can automatically move towards the axis of the lid body, thus automatically clamping the pressure cooker and improving the safety of using the pressure cooker.

[0054] 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

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figure 1As shown in the illustration, this application provides a pressure cooker lid that can be fitted onto a pot body, forming a pressure cooker together with the pot body. The pressure cooker lid includes a detachably connected lid body 10 and a clamping device 20. For example, the clamping device 20 can be connected to the lid body 10 by screws or clips. When the pressure cooker lid is fitted onto the pot body, the clamping device 20 can simultaneously clamp the pressure cooker lid and the pot body, thereby achieving a reliable connection between the pressure cooker lid and the pot body. The lid body 10 is provided with a sealing ring, a pressure limiting valve 101, and a check valve 102. The sealing ring is used to form a seal between the pressure cooker lid and the pot body, the pressure limiting valve 101 is used to limit the maximum pressure inside the pot, and the check valve 102 is used to establish a sealed state or a pressure relief state.

[0059] Furthermore, the clamping device 20 includes a support member 1 and two clamps 2. The support member 1 is used to connect to the lid 10, that is, the support member 1 forms the main body of the clamping device 20, and all other components of the clamping device 20 are installed on the support member 1, so that the clamping device 20 can be used as a whole, making it convenient for the pressure cooker lid to be disassembled, cleaned and maintained as needed. The two clamps 2 are arranged opposite each other on both sides of the axis of the lid 10. The clamps 2 are slidably connected to the support member 1, and the clamps 2 slide radially on the support member 1 along the lid 10 to clamp or unclamp. When the clamps 2 move toward the axis of the lid 10 and clamp, a firm connection is formed between the pressure cooker lid and the pot body. When the clamps 2 move away from the axis of the lid 10 and unclamp, the pressure cooker lid can be closed onto the pot body or removed from the pot body.

[0060] When the stop valve 102 rises, the pressure cooker lid is sealed, creating high pressure inside the pot. The stop valve 102 also blocks the clamp 2, preventing it from moving away from the axis of the lid 10, thus maintaining a stable clamped state and preventing the pressure cooker lid from being opened under high pressure. When the stop valve 102 falls, the pressure cooker lid is depressurized, releasing the pressure inside the pot. The stop valve 102 then avoids the clamp 2, allowing it to move normally away from the axis of the lid 10, thus enabling the pressure cooker lid to be opened normally.

[0061] like Figures 1-3As shown, the clamping device 20 also includes an operating member 3. The operating member 3 includes a connecting shaft 31, and the operating member 3 is flipped and connected to the support member 1 through the connecting shaft 31. The clamp 2 is provided with a guide pin 21, and the outer periphery of the connecting shaft 31 is provided with a spiral first guide groove 31a. The first guide groove 31a and the guide pin 21 are arranged in a one-to-one correspondence. The guide pin 21 slides relative to the first guide groove 31a to convert the flipping movement of the operating member 3 into the radial sliding of the clamp 2. The user only needs to apply external force to the operating member 3 to make the operating member 3 flip, which can drive the clamp 2 to slide radially along the lid 10, so that the clamp 2 can clamp or unclamp, thereby making the opening and closing operation of the pressure cooker lid easier. In addition, through the sliding cooperation between the guide pin 21 and the first guide groove 31a, the flipping movement of the operating member 3 is converted into the radial sliding of the clamp 2, which can make the movement of the clamp 2 smoother and prevent collisions or impacts caused by violent movement of the clamp 2.

[0062] Specifically, each clamp 2 is provided with a first guide groove 31a, and the spiral directions of the two first guide grooves 31a are opposite, so that the two clamps 2 can move simultaneously toward the axis of the lid 10 and clamp, or move simultaneously away from the axis of the lid 10 and release the clamp. A lid 7 can be connected to the top of the support member 1. The lid 7 can be connected to the support member 1 by means of buckles or screws, etc. The user can lift the pressure cooker lid by holding the lid 7. The connecting shaft 31 is clamped between the lid 7 and the support member 1 so that the support member 1 can maintain the integrity of its own structure.

[0063] Furthermore, the clamping device 20 also includes a first elastic element 4 (e.g., a spring). The first elastic element 4 connects the two clamps 2 to force the clamps 2 to clamp. Specifically, the first elastic element 4 is connected to one end of the clamp 2 near the axis of the lid 10. The first elastic element 4 is a pre-tensioned spring. Under the traction of the first elastic element 4, the two clamps 2 can automatically move towards the axis of the lid 10, thus automatically clamping the pressure cooker lid and improving the safety of using the pressure cooker.

[0064] like Figures 4-7 As shown, the operating component 3 also includes a gripping part 32, which forms a closed ring with the connecting shaft 31. This not only allows the connecting shaft 31 and the gripping part 32 to reinforce each other and prevent damage such as breakage of the operating component 3, but also improves the stability and comfort of the user holding the operating component 3.

[0065] Furthermore, the operating part 3 can be directly used as a handle for the pressure cooker lid. When the clamp 2 is clamping, the gripping part 32 is approximately parallel to the lid body 10; when the clamp 2 is released, the gripping part 32 is approximately perpendicular to the lid body 10. By lifting the handle, the user can release the clamp 2 and remove the pressure cooker lid from the pot, further simplifying the use of the pressure cooker.

[0066] Furthermore, a second guide groove 31b is provided on the outer periphery of the connecting shaft 31. The second guide groove 31b is located at one end of the first guide groove 31a near the axis of the lid 10. The second guide groove 31b communicates with the first guide groove 31a and extends circumferentially away from the first guide groove 31a. That is, the wall of the first guide groove 31a is approximately perpendicular to the axis of the connecting shaft 31. When the guide pin 21 moves to the end of the first guide groove 31a near the axis of the lid 10, the clamp 2 clamps. At this time, the operating member 3 can be further rotated to allow the guide pin 21 to slide into the second guide groove 31b. The second guide groove 31b provides a supporting force to the guide pin 21 along the axial direction of the lid 10, which ensures that the clamp 2 remains stably in the clamping position and prevents the position of the clamp 2 from changing during use, thus affecting the safety of the pressure cooker.

[0067] Specifically, once the clamp 2 has clamped, even if the clamp 2 is accidentally subjected to an outward pulling force (e.g., accidental collision or user misoperation), the clamp 2 can remain stably in the clamped position. Only when the operating member 3 is reversed and the guide pin 21 slides from the second guide groove 31b into the first guide groove 31a can the clamp 2 move along the axial direction of the cover 10 and release the clamp.

[0068] Furthermore, the connecting shaft 31 includes a first shaft segment 311 and a second shaft segment 312 coaxially arranged. There are two first shaft segments 311, which are positioned opposite each other at the two ends of the second shaft segment 312. The first shaft segments 311 are rotatably connected to the support member 1, thereby enabling the operating member 3 to be flipped and connected to the support member 1. The outer diameter of the second shaft segment 312 is larger than the outer diameter of the first shaft segment 311. A first guide groove 31a is disposed on the outer periphery of the second shaft segment 312. By placing the first guide groove 31a on the larger diameter second shaft segment 312, the contact stress between the guide pin 21 and the first guide groove 31a can be reduced, decreasing the possibility of wear, deformation, or other abnormalities in the guide pin 21 or the first guide groove 31a, effectively extending the service life of the pressure cooker lid.

[0069] The first shaft segment 311 may be provided with a locking groove 311a, and the support member 1 may be connected with a locking member (not shown in the figure). The locking member and the locking groove 311a cooperate with each other to lock the operating member 3 or provide an audible prompt that the operation is in place. It should be noted that when the first shaft segment 311 and the support member 1 are provided with a cooperating locking member and locking groove 311a, the user needs to manually flip the operating member 3 to disengage the locking member from the locking groove 311a before the clamp 2 can automatically move to the locking state. When the first shaft segment 311 and the support member 1 are not provided with a cooperating locking member and locking groove 311a, the clamp 2 can automatically move to the locking state as long as the user releases the operating member 3.

[0070] Furthermore, the first shaft segment 311 is cylindrical, allowing it to achieve a larger load-bearing capacity with a smaller diameter, ensuring the stability and reliability of the flipping movement between the operating member 3 and the support member 1. The second shaft segment 312 has a fan-shaped cross-section, meaning that the second shaft segment 312 has a convex arc surface on the side facing the clamp 2 (i.e., the outer arc side) and a concave arc surface on the side away from the clamp 2 (i.e., the inner arc side). This design minimizes the material used in the second shaft segment 312 while maintaining its strength, reducing the overall weight of the connecting shaft 31, and also avoids the large diameter of the second shaft segment 312 occupying too much space, making the overall structure of the pressure cooker lid more compact.

[0071] Furthermore, the second shaft segment 312 includes two first annular segments 312a, which are arranged opposite each other along the axial direction of the connecting shaft 31. A first guide groove 31a is provided on the outer periphery of each first annular segment 312a, that is, a first guide groove 31a is provided on the outer periphery of each first annular segment 312a. The opposite side of the two first annular segments 312a is a first end face 312c, which is perpendicular to the axis of the connecting shaft 31, so that an approximately triangular support area 312e is formed between the wall of the first guide groove 31a and the first end face 312c. When a user forcibly opens the pressure cooker under abnormal conditions (e.g., the pot is under high pressure, the stop valve 102 is in the rising state, etc.), as the user flips the operating part 3, the clamp 2 cannot move outward to release the clamping, so the squeezing force of the guide pin 21 on the wall of the first guide groove 31a will gradually increase. By setting an approximately triangular support area 312e, the support strength can also gradually increase, thereby preventing the wall of the first guide groove 31a from being subjected to excessive force and causing deformation or cracking.

[0072] Furthermore, the first annular segment 312a is connected to the first shaft segment 311, and the opposite sides of the two first annular segments 312a are the second end faces 312d. The second end face 312d is located within the length range of the first shaft segment 311, meaning that there is an axially overlapping area between the first annular segment 312a and the first shaft segment 311. Since the second end face 312d is perpendicular to the axis of the connecting shaft 31, the length of this axially overlapping area remains uniform. The inner diameter of the first annular segment 312a is smaller than the outer diameter of the first shaft segment 311, meaning that there is a radially overlapping area between the first annular segment 312a and the first shaft segment 311. Therefore, by providing both axial and radial overlapping areas between the first annular segment 312a and the first shaft segment 311, the overall structural strength of the connecting shaft 31 can be guaranteed, preventing breakage or other damage between the first annular segment 312a and the first shaft segment 311.

[0073] Furthermore, the second shaft segment 312 includes a second annular segment 312b, which is disposed between the two first annular segments 312a. The inner diameter of the second annular segment 312b is larger than the inner diameter of the first annular segment 312a, and the outer diameter of the second annular segment 312b is smaller than the outer diameter of the first annular segment 312a. That is, the thickness of the second annular segment 312b is smaller than the thickness of the first annular segment 312a, and both the inner and outer sides of the second annular segment 312b are recessed into the first annular segment 312a. On the one hand, by connecting the two first annular segments 312a through the second annular segment 312b, the bending and other deformation of the first annular segment 312a are reduced, ensuring that the two first annular segments 312a move synchronously, thereby ensuring that the two clamps 2 move synchronously; on the other hand, since the second annular segment 312b is subjected to less force, the use of a thinner second annular segment 312b can save materials, reduce the overall weight of the pressure cooker lid, and also create clearance space for the first elastic element 4, making the overall structure more compact.

[0074] In some embodiments, a second elastic element 5 may be installed on the connecting shaft 31. The second elastic element 5 can be installed at any position on the connecting shaft 31. The second elastic element 5 is a torsion spring. One torsion arm of the second elastic element 5 is supported on the connecting shaft 31, and the other torsion arm is supported on the support member 1 or the cover 7, etc., to force the operating member 3 to move with the clamp 2 in the direction of clamping. When the user applies force to the operating member 3 to release the clamping device 20, the second elastic element 5 is squeezed by a torsional force. When the user releases the operating member 3, under the rebound force of the second elastic element 5, the operating member 3 automatically rotates in the opposite direction, thereby reducing or eliminating the resistance of the operating member 3 to the clamp 2, making it easier for the clamp 2 to move in the direction of clamping, preventing the operating member 3 or the clamp 2 from jamming or locking, ensuring that the clamp 2 can automatically move to the clamping state, and further improving the safety of using the pressure cooker.

[0075] In one embodiment, the second elastic member 5 is mounted on the inner arc side of the second shaft segment 312 (e.g., the inner arc side of the first annular segment 312a). Mounting the second elastic member 5 in the recessed area of ​​the second shaft segment 312 allows for a more compact overall structure. Furthermore, the circumferential edge of the second shaft segment 312 itself can act as a stop for the torsion arm of the second elastic member 5, eliminating the need for a dedicated stop structure on the connecting shaft 31 for the torsion arm and simplifying the overall structure.

[0076] Furthermore, a connecting post 6 is provided on the inner arc side of the second shaft segment 312. The connecting post 6 is provided in a one-to-one correspondence with the first shaft segment 311. The connecting post 6 is detachably connected (e.g., threaded connection) to the end face of the first shaft segment 311, so that the connecting post 6 forms a cantilever support state. Two annular limiting flanges 61 are provided at intervals on the outer periphery of the connecting post 6. The limiting flanges 61 are integrally formed on the connecting post 6. The second elastic member 5 is sleeved on the connecting post 6 and is located between the two limiting flanges 61. On the one hand, it can avoid the narrow operating space of the connecting shaft 31, so that the second elastic member 5 and the connecting post 6 can be assembled into a whole in the disassembled state, and then the whole can be connected to the first shaft segment 311, making the assembly operation of the second elastic member 5 more convenient. On the other hand, the two limiting flanges 61 form an axial limit on the second elastic member 5, which can prevent the second elastic member 5 from moving or shifting axially during use, causing unnecessary wear between the second elastic member 5 and the connecting shaft 31 and other components.

[0077] In addition, this application provides a pressure cooker, which includes 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 20 can simultaneously clamp the pressure cooker lid and the pot body.

[0078] 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.
