[0002] The primary function of a pressure cooker lid is to securely lock onto the pressure cooker while ensuring safety and ease of operation. Traditional pressure cookers use a rotating lid to open, resulting in a bulky lid with a handle that is inconvenient to store. Some lid designs eliminate the external handle, but these have several drawbacks:

[0003] 1. The lid locking mechanism is not secure and stable enough;

[0004] 2. The pot lid is not easy to operate. Utility Model Content

[0005] In order to solve the technical problems and shortcomings of the prior art, the present invention provides a pressure cooker lid and pressure cooker that are easy to operate safely, and can improve the locking stability and ease of operation of the lid.

[0006] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0007] A pressure cooker lid that is easy to operate safely includes a lid body, a panel assembly, and clamps. The panel assembly is mounted on the top of the lid body. The panel assembly drives the two clamps to open and close. The panel assembly includes a housing, a locking button, an unlocking button, a drive base, a drive cover, a push block, a gear, a slide rail, a rack one, and a rack two.

[0008] Rack 1 and rack 2 are slidably mounted on a slide rail. A gear that simultaneously engages rack 1 and rack 2 and synchronously drives rack 1 and rack 2 to move relative to each other is rotatably mounted in the middle of the slide rail. A clamp is fixedly connected to the outer end of each rack 1 and rack 2.

[0009] The drive seat is mounted above the slide rail, and the push block is slidably fitted inside the drive seat. The bottom of the push block is fixedly connected to rack one or rack two. The drive cover is fixed on the drive seat to close the push block. The locking button and unlocking button are mounted between the housing and the drive cover and are used to push the push block to the left or right when pressed down.

[0010] Preferably, a spring is fitted between the unlock button and the drive cover, and the spring provides elasticity to keep the unlock button from falling off.

[0011] Preferably, the locking button, unlocking button, and push block are engaged by inclined surfaces. The push block is provided with a movable groove into which the locking button and unlocking button extend. The movable groove is provided with a ramp surface, which is located on the outer side.

[0012] Preferably, the bottom of the push block is fixedly connected to rack one or rack two via a plug rod.

[0013] Preferably, a guide groove is provided on rack one or rack two, and a guide rod is fixed on the housing, the guide rod being inserted into the guide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model saves space by placing the panel assembly above the lid, allowing for easy access and operation of the panel assembly to lock and unlock the lid. By pressing the locking button, the push block moves left and right, which in turn drives rack one or rack two to move synchronously. Since rack one and rack two are engaged by gears, the force is stable, and the movements are synchronized without difference, thus allowing the clamps to hold the lid and pot body more firmly. Rack one and rack two are also restricted to sliding on the slide rail, making the movement more stable and smooth.

[0019] 2. In this utility model, a spring is set separately on the unlock button for resetting. This allows the system to distinguish between the unlocked and locked states after operation. If the button is in the locked state, it will not spring back to reset when pressed, thus enabling differentiation.

[0020] 3. The combination of the ramp surface and the locking and unlocking buttons makes assembly simple and the operation reliable. The insertion rod is used to assemble rack one or rack two for fixation, which can improve assembly efficiency. Furthermore, the guide rod and guide groove are used for further movement limitation, which can greatly improve the reliability of the clamp opening and closing action.

[0033] Example:

[0034] This invention discloses a pressure cooker lid that is easy to operate safely. For ease of understanding, please refer to... Figure 1 , Figure 2 and Figure 3 The diagram illustrates the entire pressure cooker, highlighting the key improvement in the pressure cooker lid. The overall structure is shown for ease of understanding.

[0035] This pressure cooker lid design includes a lid body 1, a panel assembly 2, and clamps 3. Combined with... Figure 3 , Figure 4 and Figure 5 The top of the cover 1 is equipped with a panel assembly 2, which drives two clamps 3 to open and close.

[0036] Specifically, regarding panel assembly 2, panel assembly 2 includes housing 21, locking button 22, unlocking button 23, drive base 24, drive cover 25, push block 26, gear 27, slide rail 28, rack one 291, and rack two 292. Rack one 291 and rack two 292 are slidably mounted on slide rail 28. Gear 27, which is a cylindrical gear, is rotatably mounted in the middle of slide rail 28. It simultaneously meshes with rack one 291 and rack two 292, so that it synchronously drives rack one 291 and rack two 292 to move relative to each other. In this design, the driving force does not act directly on gear 27, but on one of the racks, while the other rack slides synchronously in the opposite direction due to the transmission action of gear 27.

[0037] A clamp 3 is fixedly connected to the outer end of each of the racks 291 and 292. The fixing method here is welding or integral connection.

[0038] The drive seat 24 is mounted above the slide rail 28. The push block 26 is slidably fitted inside the drive seat 24. The bottom of the push block 26 is fixedly connected to rack 1 291 or rack 292. The drive cover 25 is fixed on the drive seat 24 to close the push block 26. The locking button 22 and the unlocking button 23 are mounted between the housing 21 and the drive cover 25 and are used to push the push block 26 to the left or right when pressed down.

[0039] Therefore, the basic working principle of this solution is as follows: by setting the panel assembly 2 above the lid 1, the surrounding space is saved, and the panel assembly 2 can be operated while being easily picked up, so as to lock and unlock the pot lid. By pressing the locking button 22, the push block 26 is pushed to move left and right, and then the rack 1 291 or rack 2 292 moves synchronously. Since rack 1 291 and rack 2 292 are connected by gear 27, the force is stable, the movement is synchronous and there is no difference, so that the clamp 3 can better hold the lid 1 and the pot 10 firmly. Rack 1 291 and rack 2 292 are also restricted to slide on the slide rail 28, which is more stable and smooth.

[0040] Furthermore, for safe and reliable operation, a spring 4 is installed between the unlock button 23 and the drive cover 25. The spring 4 provides elasticity to keep the unlock button 23 from falling off. No spring 4 is installed between the lock button 22 and the drive cover 25. The spring 4 is installed separately on the unlock button 23 for reset, allowing the user to distinguish between the unlocked and locked states after operation. If it is in the locked state, the lock button 22 will not spring back to reset when pressed, thus distinguishing the state. Alternatively, a spring can also be installed on the lock button 22. Custom designs can be made according to user needs. In this case, the lock button 22 will remain in a non-falling state and will reset after being pressed.

[0041] To ensure stable force distribution on the push block 26, the locking button 22, the unlocking button 23, and the push block 26 are fitted together by inclined surfaces. The push block 26 is provided with a movable groove into which the locking button 22 and the unlocking button 23 extend. The movable groove is provided with a ramp surface 261, which is located on the outer side. This not only makes the assembly of the push block 26 simple and reliable, but also ensures smooth force distribution and movement.

[0042] To improve assembly efficiency and facilitate driving, the bottom of push block 26 is fixedly connected to rack one 291 or rack two 292 via insert rod 121. (See attached...) Figure 5 For example, the movement of push block 26 directly drives the movement of rack 292. (See attached image) Figure 5 The example shown is a preferred case. Equivalent variations under the same design concept can produce several similar examples. For instance, placing the insert rod 121 on the rack 291 and fitting it onto the push block 26 achieves the same effect. Due to the mutual symmetrical approximation of this structure, equivalent derivations can be made based on this example.

[0043] To further improve the stability of rack 1 291 or rack 2 292, a guide groove 5 is provided on rack 1 291 or rack 2 292, and a guide rod 6 is fixed on the housing 21, with the guide rod 6 inserted into the guide groove 5. This guides the sliding direction.

[0044] In other further optimization solutions, a safety valve 7 (check valve) is installed on the lid 1. The safety valve 7 (check valve) is an existing component, commonly found in pressure cookers. When the lid is closed, the pressure inside the pressure cooker is relatively high, and this safety valve 7 will rise upwards. If the pressure inside drops, it will automatically fall down due to gravity. This solution is based on the existing situation.

[0045] A valve hole 8 is provided on the housing 21 for the safety valve 7 to move up and down, and a locking hole 9 is provided on rack one 291 or rack two 292 for the safety valve 7 to be inserted and removed. This allows for safe operation in conjunction with the raising and lowering action of the safety valve 7 (check valve). When the pressure is very high, it is not advisable to open the pot lid. At this time, the safety valve 7 (check valve) will extend, Figure 3 As shown in the diagram, it is inserted into the lock hole 9 and the valve hole 8, thereby preventing the movement of rack one 291 or rack two 292. Regardless of whether the user presses the unlock button 23, the unlock button 23 will be difficult to press down. Only when the internal pressure is normal and the safety valve 7 drops can the unlock button 23 be pressed to open the pot lid.

[0046] In this design, to ensure stable movement of the push block 26, a spring 4 is installed in the middle of the drive base 24 to catch it, and a corresponding slot 123 is provided on the push block 26. This allows the push block 26 to remain in either a stable unlocked or locked position.

[0047] Based on the above scheme, a pressure cooker with a pressure cooker lid that incorporates the above scheme can be manufactured.

[0048] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
