[0002] A pressure cooker, also known as a pressure pot or pressure casserole, is a type of kitchen cookware. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus speeding up the cooking process. It can heat food to over 100°C. In high-altitude areas, pressure cookers avoid the problem of water's boiling point lowering, preventing food from cooking properly, and are characterized by time and energy savings.

[0003] Existing pressure cookers typically have an upper handle on one side of the lid that integrates with the lower handle on the pot body. The edges of the lid and pot body have interlocking clips. The lid is connected to the pot body by first misaligning the clips and then rotating the lid. However, this misaligned clip system is difficult to align properly, and improper force can easily cause the lid to not close tightly, leading to safety issues such as steam leakage.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the pot lid and pressure cooker of this utility model in detail with reference to the embodiments and accompanying drawings.

[0028] <Example 1>

[0029] This embodiment proposes a pressure cooker 100, which has a lid 10 and a lid body 20. The lid 10 is detachably mounted on the lid body 20, and the lid body 20 is provided with a handle. The lid 10 includes a lid body 1, at least a pair of locking parts 2, and an unlocking part, such as... Figure 1 As shown, this embodiment includes a pair of locking parts 2. The cover 1 is circular and has an air valve mounted on it. The pair of locking parts 2 cover the edge of the cover 1 and are arranged opposite to each other. The locking parts 2 have a locking configuration that combines the cover 1 with the pot body 20 and an unlocking configuration that allows the cover 1 to be separated from the pot body 20. In the locking configuration, as... Figure 2As shown, the locking part 2 fastens the edges of the lid 1 and the pot body 20 together, thus fixing the lid 1 and the pot body 20 together. In the unlocked configuration, the locking part 2 disengages from the pot body 20, thereby allowing the lid 1 to be removed from the pot body 20 and separated from the pot body 20. The locking part 2 is arc-shaped and has an upper edge 21, a lower edge 22, and a connecting edge 23. When locked, the upper edge 21 is located above the edge of the lid 1, and the lower edge 22 is located below the edge of the pot body 20, so that the vertical projections of the locking part 2, the lid 1, and the opening edge of the pot body 20 overlap, allowing the lid 1 and the pot body 20 to be connected together by the locking part 2. The unlocking part is provided on the lid 1 and is linked with the locking part 2 to drive the locking part 2 to move. When the locking part 2 is moved by the unlocking part to a position where its projection on the pot body 20 in the vertical direction does not overlap (such as moving the locking part 2 out of the pot body 20), the lid 1 can be removed and separated from the pot body 20.

[0030] Specifically, the unlocking part has a locking button 31, an unlocking button 32, and at least one pair of connectors. The number of connectors is the same as the number of locking parts 2, and the connectors correspond one-to-one with the locking parts 2. Therefore, in this embodiment, a pair of connectors is used for description. Both the locking button 31 and the unlocking button 32 are movably mounted on the cover 1, such as... Figure 2 As shown, the two connectors are the first connector 5A and the second connector 5B, and the pair of locking parts 2 are the first locking part 2A and the second locking part 2B. The outer end of the first connector 5A is fixed to the first locking part 2A, and the outer end of the second connector 5B is fixed to the second locking part 2B. The connection between the connector and the locking part can be fixed by welding or other fixing methods.

[0031] The unlocking part also has a first gear set and a second gear set, which are linked to the unlocking button 32 and the locking button 31 respectively. When the unlocking button 32 is pressed, the first gear set and the second gear set drive the two connecting parts to move radially outward, so that the locking part 2 changes from the locked configuration to the unlocked configuration. When the locking button 31 is pressed, the second gear set and the first gear set drive the two connecting parts to move radially inward, so that the locking part 2 changes from the unlocked configuration to the locked configuration.

[0032] Specifically, the first gear set includes a first gear 61 and a first rack 62. One end of the first rack 62 meshes with the first gear 61, and the other end is connected to the first connector 5A. A first drive rod 611 is provided on the end face of the first gear 61 for linkage with the unlock button 32. When the unlock button 32 is pressed, the unlock button 32 can act on the first drive rod 611, causing the first gear 61 to rotate, thereby driving the first connector 5A to move radially outward.

[0033] The second gear set includes a second gear 63 and a second rack 64. One end of the second rack 64 meshes with the second gear 63, and the other end is connected to the second connector 5B. A second drive rod 631 for linkage with the locking button 31 is provided on the end face of the second gear 63. When the locking button 31 is pressed, the locking button 31 can act on the second drive rod 631. At this time, the second gear 63 rotates, thereby driving the second connector 5B to move radially inward.

[0034] The first gear 61 meshes with the second gear 63, so that when the first gear 61 is rotated by the unlock button 32, it also drives the second gear 63 to rotate, causing the second connecting member 5B to move radially outward. At this time, the first connecting member 5A and the second connecting member 5B move outward synchronously and open, thus simultaneously allowing both locking parts 2 to leave the pot body 20 and achieve the unlocking configuration. Similarly, when the second gear 63 is rotated by the locking button 31, it also drives the first gear 61 to rotate, causing the first connecting member 5A to move radially inward. At this time, the first connecting member 5A and the second connecting member 5B move inward synchronously and retract, thus simultaneously allowing both locking parts 2 to cover the edge of the pot body 20 and achieve the locking configuration.

[0035] The pot lid 1 also includes a mounting bracket 4, which can be mounted on the lid body 1 via connectors (such as pins, bolts, etc. for fixing). A mounting cavity 41 for mounting the first gear 61 and the second gear 63 is formed in the middle of the mounting bracket 4. An unlocking button 32 and a locking button 31 are respectively movably disposed on the top of the mounting bracket 4, and a reset element (such as a spring 47) is provided between the unlocking button 32 and the locking button 31 and the mounting bracket 4. Specifically, the mounting bracket 4 has a receiving frame 4A and a fixing frame 4B. The receiving frame 4A is a hollow square body with an open top. The fixing frame 4B is fixed inside the receiving frame 4A. The mounting cavity 41 is formed between the middle of the fixing frame 4B and the middle of the receiving frame 4A. The first gear 61 and the second gear 63 are arranged side-by-side in the mounting cavity 41.

[0036] like Figure 3 As shown, the side of the fixing frame 4B and the side of the receiving frame 4A can be combined to form a panel 40. A first driving groove 42 and a second driving groove 43, respectively corresponding to the first driving rod 611 and the second driving rod 631, are provided on the panel 40. The first driving groove 42 has a first end 421 and a second end 422, and the second driving groove 43 has a third end 431 and a fourth end 432. The first end 421 and the third end 431 are located on the fixing frame 4B and are at the same or similar height; the second end 422 and the fourth end 432 are located on the receiving frame 4A and are at the same or similar height. Figure 3As shown, the device is currently in a locked configuration, with the first drive rod 611 at the first end 421 and the second drive rod 631 at the fourth end 432. When the unlock button 32 is pressed, causing the two gears to rotate, the first drive rod 611 rolls along the first drive groove 42 and enters the second end 422. Simultaneously, the second drive rod 631 moves along the second drive groove 43 and enters the third end 431. Therefore, when the first drive rod 611 is at the second end 422, the second drive rod 631 is at the third end 431. That is, the first drive rod 611 and the second drive rod 631 are staggered.

[0037] A first limiting rod 612 is provided on the end face of the first gear 61, and a second limiting rod 632 is provided on the end face of the second gear 63. The panel 40 of the mounting bracket 4 is provided with a first limiting groove 44 and a second limiting groove 45 corresponding to the first limiting rod 612 and the second limiting rod 632, respectively. The first limiting groove 44 has a fifth end 441 and a sixth end 442, and the second limiting groove 45 has a seventh end 451 and an eighth end 452. The fifth end 441 and the seventh end 451 are located on the fixing bracket 4B and are at the same or similar height. The sixth end 442 and the eighth end 452 are located on the receiving bracket 4A and are at the same or similar height. When the first limiting rod 612 is at the fifth end 441, the second limiting rod 632 is at the eighth end 452. When the first limiting rod 612 is at the sixth end 442, the second limiting rod 632 is at the seventh end 451. That is, the first limiting rod 612 and the second limiting rod 632 are arranged in a staggered manner.

[0038] The locking button 31 has an outer cover and a built-in locking moving block 311 (the cover and the locking moving block 311 can be integrated or separate). The cover is limited between itself and the fixing frame 4 by a snap-fit ​​on its edge. The projection of the locking moving block 311 and the second drive rod 631 in the moving direction of the locking moving block 311 overlaps. Therefore, when the locking button 31 is pressed, the locking moving block 311 presses on the second drive rod 631, thereby driving the second gear 63 to rotate. The unlocking button 32 has an outer cover and a built-in unlocking moving block 321 (the cover and the unlocking moving block 321 can be integrated or separate). The cover is limited between itself and the fixing frame 4 by a snap-fit ​​on its edge. The projection of the unlocking moving block 321 and the first drive rod 611 in the moving direction of the unlocking moving block 321 overlaps. Therefore, when the unlocking button 32 is pressed, the unlocking moving block 321 presses on the first drive rod 611, thereby driving the first gear 61 to rotate. The locking moving block 311 and the unlocking moving block 321 have the same structure and are symmetrically arranged. The outer ends of the locking moving block 311 and the unlocking moving block 321 are respectively provided with guide holes 3111 and 3211. The guide posts 3111 and 3211 cooperate with the guide posts 48 on both sides of the fixed frame 4B, so that the locking moving block 311 and the unlocking moving block 321 can move stably.

[0039] In this embodiment, the first limiting rod 612, the second limiting rod 632, the first driving rod 611, and the second driving rod 631 are all cylindrical. The axial length of the first limiting rod 612 is less than the axial length of the first driving rod 611, so that when the unlocking moving block 321 moves downward, it can only act on the first driving rod 611 and not on the first limiting rod 612. The axial length of the second limiting rod 632 is less than the axial length of the second driving rod 631, so that when the locking moving block 311 moves downward, it can only act on the second driving rod 631 and not on the second limiting rod 632.

[0040] like Figure 4As shown, this is the locked configuration of the first gear 61 and the second gear 63. In this state, pressing the unlock button 32 causes the unlocking moving block 321 to act on the first drive rod 611, thereby pushing the first gear 61 to rotate clockwise, causing the first rack 62 to move outward (in the direction of the arrow in the figure). Since the second gear 63 meshes with the first gear 61, the second gear 63 rotates counterclockwise, causing the second rack 64 to move outward (in the direction of the arrow in the figure), thus gradually switching to the unlocked configuration. When the first gear 61 rotates to the point where the first limit rod 612 enters the fifth end 441, the first gear 61 stops rotating clockwise; at this time, the second drive rod 631 on the second gear 63 rotates into the third end 431, and the second gear 62 also stops rotating. After the pressure on the unlock button 32 is removed, the unlock button 32 will reset under the action of the return spring, and since the two gears stop rotating, the locking part 2 can remain in the unlocked configuration, making it convenient for the user to remove the lid 10 or put it back on the pot body 20.

[0041] When the cover needs to be closed, in the unlocked configuration, pressing the locking button 31 causes the locking moving block 311 to act on the second drive rod 631, thereby pushing the second gear 63 to rotate clockwise, causing the second rack 64 to move inward; since the first gear 61 meshes with the second gear 63, the first gear 61 rotates counterclockwise, causing the first rack 62 to move inward, thus gradually changing to the locked configuration. When the first gear 61 rotates until the first drive rod 611 enters the first end 421, the first gear 61 stops rotating counterclockwise; at this time, the second limiting rod 632 on the second gear 63 rotates into the seventh end 451, and the second gear 62 also stops rotating (as shown). Figure 3 (State of the lock). After the pressure on the locking button 31 is removed, the locking button 31 will reset under the action of the reset spring, and the two gears will stop rotating, so the locking part 2 can remain in the locked position, thus fixing the lid 10 and the pot body 20 relative to each other.

[0042] To make the gear rotation more stable, the first limiting rod 612, the second limiting rod 632, the first driving rod 611 and the second driving rod 631 mentioned above can be provided on both end faces of the first gear and the second gear. The locking moving block 311 (unlocking moving block 321) can act on the second driving rod 631 (first driving rod 611) on both the front and rear sides at the same time.

[0043] Both connectors are plate-shaped and have basically the same structure, such as Figure 6As shown, taking the second connector 5B as an example, one end of the second connector 5B is fixed to the second locking part 2B, and the other end has a connecting rod 51 that can be inserted into the second rack 64. The connecting rod 51 and the second rack 64 are fixedly connected, so that the second rack 64 can move the second connector 5B during movement, thereby moving the locking part 2. Figure 5 As shown, the mounting bracket 4 has a base plate 46 at the bottom of the mounting cavity 41. The base plate 46 has a limiting hole 461 for the connecting rod 51 to pass through. The limiting hole 461 is racetrack shaped, which can guide the movement of the connecting rod 51 on the one hand, and limit the movement of the connecting rod 51 on the other hand.

[0044] <Example 2>

[0045] Based on Embodiment 1 above, this embodiment further includes a locking valve 7 movably disposed on the lid body 1, such as... Figure 7 As shown, one of the connectors (the second connector 5B in this embodiment) has a lock hole 52 corresponding to the lock valve 7 at the end near the one fixed to the locking part 2. The lock hole 52 has a first hole 521 and a second hole 522 that are interconnected. The inner diameter of the first hole 521 is D1 and the inner diameter of the second hole 522 is D2. The lock valve 7 has an enlarged part 71 and a reduced part 72 that are both cylindrical. The outer diameter of the enlarged part 71 is D3 and the outer diameter of the reduced part is D4, wherein D3 < D2 < D4 ≤ D1. The enlarged part 71 is installed on the cover 1 by a sealing ring 73.

[0046] The locking valve 7 can move on the lid 1 under the action of air pressure. The mounting bracket 4 has a through hole corresponding to the second hole 522. When the air pressure inside the pot 20 rises and is higher than the external atmospheric pressure, the locking valve 7 is pushed upward by the internal air pressure, and the top of the reduced part 72 extends into and out of the through hole on the mounting bracket 4. At this time, the enlarged part 71 is at the second hole 522 (e.g., Figure 6 As shown in the diagram, due to the obstruction of the locking valve 7, the second connecting piece 5B cannot move, so even pressing the unlock button 32 will not unlock it. When the gas pressure inside the pot body 20 decreases, once it drops below the outside gas pressure, the locking valve 7 will move downwards under the push of the outside gas, and the top of the shrinkage part 72 will disengage from the through hole on the mounting bracket 4, and the shrinkage part 72 will move to the second hole 522 (as shown). Figure 7 (As shown in the diagram), pressing the unlock button 32 will unlock the lid. The locking valve 7 prevents the lid 10 from being accidentally opened under high pressure, thus improving safety.

[0047] The above embodiments are merely illustrative of specific implementations of the present invention, and the present invention is not limited to the scope of the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
