Description

Technical Field

[0001] This utility model relates to a pressure cooker, and more particularly to a pressure cooker with a push-button switch lid. Background Technology

[0002] Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure. By applying pressure to water, the water can reach a higher temperature without boiling, thus speeding up the cooking process. They can heat food to over 100°C. In high-altitude areas, pressure cookers can avoid the problem of water boiling point decreasing and food not cooking properly.

[0003] During the use of a pressure cooker, due to the high pressure inside the pot, the lid needs to be locked. Before opening the lid, the pressure inside the pot needs to be released. However, many pressure cookers currently in use have complex lid locking mechanisms, making it inconvenient to open and lock the lid. Utility Model Content

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] This embodiment mainly describes a pressure cooker with a push-button lid, as follows:

[0031] like Figure 1-6As shown, a pressure cooker with a push-button switch lid includes a pot body 4 and a lid 1 that fits onto it. The lid 1 is provided with two radially movable clamping mechanisms 3. Each clamping mechanism 3 includes a toothed plate 3b and a clamping part 3a. A drive gear 15 is provided between the two toothed plates 3b. One end of the toothed plate 3b is fixedly connected to the clamping part 3a, and the other end of the toothed plate 3b is engaged with the drive gear 15. The lid 1 is also provided with a flip-up handle 2, which is connected to one of the toothed plates 3b. When the handle 2 moves one of the toothed plates 3b, the drive gear 15 drives the two toothed plates 3b to move the two clamping parts 3a simultaneously, thereby achieving the clamping or opening operation of the pot body 4 and the lid 1.

[0032] like Figure 5 As shown, a fixing plate 19 is provided on the cover 1, and a sliding groove 21 is provided on the fixing plate 19. A transmission block 14 is provided in the sliding groove 21. The transmission block 14 slides in the sliding groove 21 on the fixing plate 19. An installation hole 20 is provided on the transmission block 14. The installation hole 20 is connected to one of the toothed plates 3b through a connecting rod 18. The connecting rod 18 is fixedly connected to the toothed plate 3b.

[0033] like Figure 3 , Figure 4 As shown, a protrusion 7 extends from the handle 2, and a slot 13 is provided on one end of the transmission block 14. The protrusion 7 is embedded in the slot 13 to connect the handle 2 and the transmission block 14. When the handle 2 is rotated, the protrusion 7 on the handle 2 drives the transmission block 14 to slide in the slide groove 21 on the fixed plate 19. The transmission block 14 drives the toothed plate 3b to move through the connecting rod 18 in the mounting hole 20. The toothed plate 3b drives the other toothed plate 3b to open with the clamping part 3a through meshing with the drive gear 15.

[0034] like Figure 6 As shown, the handle 2 has several toothed grooves 11, and the fixing plate 19 is provided with a tapered rod 17 that is adapted to the toothed grooves 11. A spring 22 is provided between the tapered rod 17 and the fixing plate 19 to push the tapered rod 17 to move in the direction of the toothed grooves 11. When the handle 2 is rotated, the tapered rod 17 is inserted into each toothed groove 11 step by step under the action of the spring force of the spring 22, providing resistance to the rotation of the handle 2 and making the user feel better when lifting the handle 2.

[0035] like Figure 2 As shown, a connecting seat 6 is provided on the cover 1, and the handle 2 is rotatably connected to the connecting seat 6. Grooves 5 are provided on both sides of the connecting seat 6 to facilitate the user to rotate the handle 2. These grooves 5 provide the user with convenient operating space, making the rotation of the handle 2 easier and more free.

[0036] like Figure 1 , Figure 2 As shown, handle 2 has a closed position and an open position. Rotating handle 2 allows it to switch between the closed and open positions.

[0037] When the handle 2 is in the closed position, the two clamping parts 3a clamp the edges of the lid 1 and the pot body 4, and the handle 2 is attached to the lid 1 to ensure the overall aesthetics and stability of the pressure cooker in the closed state. At this time, the pressure cooker is in a sealed state and can be used for pressure cooker cooking.

[0038] As the handle 2 moves from the closed position to the open position, the handle 2 disengages from the connecting seat 6. At the same time, the handle 2 drives the toothed plate 3b to move, and the clamping part 3a, which is fixedly connected to the toothed plate 3b, opens synchronously. The lid 1 can be removed from the pot body 4. An angle is formed between the handle 2 and the lid 1. The handle 2 can be used as a support foot for the lid 1 to be placed upright, making it convenient for users to place the pot lid after cooking.

[0039] like Figure 8 As shown, the handle 2 has a closed position groove 8 and an open position groove 9. A guide arc surface 10 is provided between the closed position groove 8 and the open position groove 9 for smooth transition. The fixing plate 19 is provided with a locking block 12 that engages with the closed position groove 8 and the open position groove 9. When in the closed position, the locking block 12 is locked in the closed position groove 8 to ensure that the handle 2 is in the closed position; when in the open position, the locking block 12 is locked in the open position groove 9 to stabilize the handle 2 in the open position.

[0040] A reset spring 16 is provided between the locking block 12 and the fixing plate 19. The reset spring 16 always provides the locking block 12 with a force to engage in the closed gear slot 8 or the open gear slot 9, so as to ensure the stability and reliability of gear switching.

[0041] In summary, the operation process of a push-button pressure cooker consists of the following steps:

[0042] Closing the lid: Place the lid 1 on the pot body 4, and turn the handle 2 to the closed position. During the rotation, the handle 2 drives the toothed plate 3b to move through the transmission block 14, so that the clamping part 3a clamps the edge of the lid 1 and the edge of the pot body 4. At this time, the locking block 12 is locked into the closed position groove 8 under the action of the return spring 16, and the cone rod 17 is locked into the corresponding toothed groove 11 under the action of the spring 22, so that the clamping part 3a clamps the lid 1 and the pot body 4.

[0043] Opening the lid: After cooking is complete, turn the handle 2 to the open position. The protrusion 7 on the handle 2 drives the transmission block 14 to slide. The transmission block 14 drives the toothed part 3b to move, causing the clamping part 3a to open. After the clamping part 3a is opened, the locking block 12 is locked into the open position groove 9 under the action of the return spring 16. The user can remove the lid 1 from the pot body 4. The handle 2 and the lid 1 form an angle, which can be used as a support foot to place the lid 1 upright.
