Description

Technical Field

[0001] This utility model relates to the field of pot lid technology, and in particular to a pot lid with high safety. Background Technology

[0002] An electric pressure cooker is a type of kitchen appliance. Due to its advantages such as good cooking effect, speed, and energy saving, electric pressure cookers have entered thousands of households and become one of the essential kitchen appliances. After cooking, users can manually operate the pressure release valve to quickly release the pressure inside the pot before opening the lid, ensuring safe use.

[0003] For example, patent CN217592544U discloses a cooking appliance that can switch between the functions of an electric pressure cooker and a rice cooker, including: an outer pot, an inner pot disposed inside the outer pot, a lid disposed at the opening of the outer pot, an exhaust valve and a lever disposed on the lid, a lever disposed between the exhaust valve and the lever, one end of the lever being disposed at the bottom end of the exhaust valve, the other end of the lever being disposed at the bottom end of the lever, a slider disposed on the lever, when the slider slides and presses against one end of the lever, the other end of the lever lifts up and opens the exhaust valve; when the slider slides away from one end of the lever, the other end of the lever moves away from the bottom end of the exhaust valve, and the exhaust valve falls down and closes.

[0004] The problem with the above technology is that after cooking, the lid can be opened by sliding the lever to lift the exhaust valve, thereby reducing the pressure inside the pot. However, if the lid is opened before the pressure inside the pot has dropped to a safe level, the high-temperature gas and food inside the pot will spray out, scalding the user.

[0005] Therefore, a highly safe pot lid is proposed to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a highly secure pot lid that cannot be opened when the exhaust valve is opened to release air.

[0007] The technical solution adopted by this utility model to solve the problem is: a highly safe pot lid, including a lid body and a ring. The lid body is placed on top of the ring. A lever and an exhaust valve are movably disposed on the lid body. A lever is connected between the lever and the exhaust valve. A vertically movable limiting rod is disposed inside the lid body. The limiting rod is located below the lever, and its lower part extends to the outside of the lid body. A first magnet that can magnetically attract the limiting rod is disposed on the end of the lever away from the lever. A limiting block is disposed on the ring. When the lever moves forward, it can drive the lever to rotate, thereby causing the exhaust valve to tilt and open. The lower end of the limiting rod moves downward to the side of the limiting block, and the limiting block can block the movement of the limiting rod, thereby preventing the lid body from opening in the opening direction.

[0008] As a further improvement to the above technical solution, the cover body is provided with an installation groove, and the limiting rod is movably disposed in the installation groove.

[0009] As a further improvement to the above technical solution, the end of the lever has a downward protrusion, and the first magnet is disposed on the protrusion.

[0010] As a further improvement to the above technical solution, a second magnet is provided on the end of the lever near the lever, which is able to magnetically attract the lever, and the second magnet is located below the lever.

[0011] As a further improvement to the above technical solution, a shaft is provided on the lever, and a bearing is provided inside the cover, with the shaft rotatably connected to the bearing.

[0012] As a further improvement to the above technical solution, a fixing block is fixedly provided on the cover, and the toggle block is movably disposed on the top of the fixing block.

[0013] As a further improvement to the above technical solution, the ring is provided with a lifting lug.

[0014] The beneficial effects of this utility model are as follows: Under normal conditions, the lever is located at the rear, the first magnet is located above the limiting rod and magnetically attracts the limiting rod, causing the limiting rod to move upward and be offset from the limiting block. At this time, the exhaust valve is in the closed state and the lid can be opened normally. After cooking, the user pushes the lever forward, which drives the lever to rotate, thereby causing the exhaust valve to tilt up and open. At this time, the first magnet disengages from the limiting rod, and the limiting rod can move downward to the side of the limiting block. The limiting block can prevent the limiting rod from moving in the opening direction, thereby restricting the opening of the lid and preventing the lid from being opened before the pressure inside the pot has dropped to a safe range, thus ensuring the user's safety.

[0027] Reference Figures 1 to 6 A highly safe pot lid includes a lid body 1 and a ring 2. The lid body 1 covers the top of the ring 2. A lever 3 and an exhaust valve 4 are movably mounted on the lid body 1. A lever 5 is connected between the lever 3 and the exhaust valve 4. A vertically movable limiting rod 6 is provided inside the lid body 1. The limiting rod 6 is located below the lever 3. The lower part of the limiting rod 6 extends to the outside of the lid body 1. A first magnet 31 that can magnetically attract the limiting rod 6 is provided on the end of the lever 3 away from the lever 5. A limiting block 21 is provided on the ring 2.

[0028] The ring 2 is fixedly connected to the pot body, and the limiting rod 6 is made of metal or the end of the limiting rod 6 is provided with a magnetic component that is magnetically attracted to the first magnet 31.

[0029] Under normal conditions, the lever 3 is located at the rearmost position, the first magnet 31 is located above the limiting rod 6 and magnetically attracts the limiting rod 6, causing the limiting rod 6 to move upward and be offset from the limiting block 21. At this time, the exhaust valve 4 is in the closed state and can open the cover 1 normally.

[0030] After cooking, the user can push the lever 3 forward, which will cause the lever 5 to rotate, thus opening the exhaust valve 4. At this time, the first magnet 31 will disengage from the limiting rod 6, and the limiting rod 6 can move downward to the side of the limiting block 21. The limiting block 21 can prevent the limiting rod 6 from moving in the opening direction, thereby limiting the opening of the lid 1 and preventing the lid 1 from being opened when the pressure inside the pot has not been reduced to a safe range, thus ensuring the user's safety.

[0031] In a preferred embodiment, in order to facilitate the installation of the limiting rod 6, an installation groove 11 is provided inside the cover 1, and the limiting rod 6 is movably disposed in the installation groove 11.

[0032] In a preferred embodiment, the end of the lever 3 extends downward with a protrusion 32, and the first magnet 31 is disposed on the protrusion 32.

[0033] In a preferred embodiment, the lever 5 is made of metal, and a second magnet 33 is provided on the end of the lever 5 near the lever 5. The second magnet 33 is located below the lever 5. When the second magnet 33 approaches the lever 5, it can magnetically attract the lever 5 and make the lever 5 rotate, thereby lifting the exhaust valve 4.

[0034] In a preferred embodiment, a shaft 51 is provided on the lever 5, and a bearing seat 12 is provided inside the cover 1, with the shaft 51 rotatably connected to the bearing seat 12.

[0035] In a preferred embodiment, a fixing block 13 is fixedly disposed on the cover 1, and a lever 3 is movably disposed on the top of the fixing block 13.

[0036] In a preferred embodiment, a lifting lug 22 is provided on the ring 2 to facilitate lifting the pot body.

[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
