Description

Technical Field

[0001] This utility model relates to a pressure cooker lid. Background Technology

[0002] Pressure cookers are commonly used cooking appliances in modern households and the catering industry. They utilize the high-pressure steam generated inside the pot to raise the boiling point of water, thereby achieving rapid cooking. To ensure safety during the cooking process and proper pressure release after cooking, pressure cookers are usually equipped with pressure relief devices on the lid, such as an exhaust valve or a pressure limiting valve.

[0003] Most existing electric pressure cookers only have a single pressure relief valve. This valve automatically regulates the pressure inside the pot during cooking and releases residual pressure after cooking. While this structure basically meets the usage requirements of a pressure cooker, it still has the following shortcomings: Due to the limited number of vents, when there is high residual pressure inside the pot, the venting speed of a single vent is limited, resulting in a long pressure relief time. Users need to wait a long time before they can safely open the lid, which affects the user experience. If a single pressure relief valve becomes stuck or blocked during use, it cannot form a redundant pressure relief path, potentially reducing the overall safety of the pressure cooker. Utility Model Content

[0004] The purpose of this invention is to provide a pressure cooker lid that enables multi-point synchronous pressure relief and improves pressure relief efficiency.

[0005] The purpose of this utility model is achieved as follows: A pressure cooker lid includes a lid, a button, a transmission component, and a pressure limiting valve. The lid has at least two accommodating cavities, each accommodating cavity has an exhaust pipe, and the pressure limiting valve is movably disposed within the accommodating cavity. The pressure limiting valve closes the corresponding exhaust pipe under the action of gravity. The pot lid is provided with a button receiving cavity, and the button is movably placed in the button receiving cavity; The accommodating cavity has an opening on its side wall. The transmission component includes a pressing part and a pushing part. The transmission component is rotatably mounted on the lid. The pushing part extends through the opening into the corresponding accommodating cavity and abuts against the corresponding pressure relief valve. The button presses down the pressing part, causing the transmission component to rotate, and the pushing part pushes the pressure limiting valve upward, so that the pressure limiting valve opens the exhaust pipe.

[0006] By setting at least two accommodating cavities and corresponding pressure-limiting valves on the pot lid, and using a button-driven transmission component to synchronously drive multiple pressure-limiting valves to open the exhaust pipe, the steam inside the pot can be quickly discharged through multiple exhaust channels. This not only significantly improves the pressure relief efficiency and shortens the waiting time for opening the lid, but also forms a dual pressure relief path. Even if one exhaust channel is abnormal, pressure can still be safely relieved through other channels, effectively improving the safety and reliability during use. Furthermore, the button operation is simple, the structure is compact, and it is easy for users to quickly complete the pressure relief action with one hand.

[0007] The objective of this utility model can also be achieved by the following technical measures: Furthermore, the pressure relief valve has an exhaust passage, and a cover is provided at the outlet of the exhaust passage. The cover has an exhaust port that connects to the exhaust passage, and the cover is provided with a blocking part. The exhaust pipe passes through the exhaust passage and abuts against the cover. When the blocking part is inserted into the outlet of the exhaust pipe, the blocking part closes the exhaust pipe. When the blocking part leaves the outlet of the exhaust pipe, the exhaust pipe is opened.

[0008] By installing a cover with an exhaust port and a plug at the exhaust channel outlet of the pressure relief valve, a controllable opening and closing structure is formed between the exhaust channel and the exhaust pipe. When the plug is inserted into the exhaust pipe outlet, it effectively seals the exhaust pipe, preventing disorderly steam leakage from the boiler; when the plug leaves the exhaust pipe outlet, it quickly opens the exhaust pipe, achieving smooth exhaust. This structure not only ensures the stability and sealing of the exhaust action but also reduces the impact of steam impact on the pressure relief valve, improving the safety and durability of the pressure relief process.

[0009] Furthermore, it also includes a handle base, which has a channel opening corresponding to the location of the accommodating cavity. The exhaust pipe is connected to the pot lid, with the inlet of the exhaust pipe extending into the pot lid. The handle base is fixed to the pot lid, and the outlet of the exhaust pipe extends into the corresponding accommodating cavity and protrudes towards the corresponding channel opening.

[0010] By setting a channel opening at the corresponding position of the handle seat and making the inlet of the exhaust pipe extend into the inside of the pot lid and the outlet extend towards the channel opening, the steam in the pot can be smoothly guided to the pot lid and discharged in the direction of the exhaust port, effectively avoiding the steam directly impacting the surface of the pot lid and reducing the risk of burns to the user.

[0011] Furthermore, it also includes a valve cap seat, which has the receiving cavity, and the valve cap seat is disposed on the handle seat. The receiving cavity passes through the corresponding channel opening and abuts against the pot lid.

[0012] By setting a valve cap seat on the handle seat and forming a receiving cavity inside the valve cap seat, the receiving cavity can pass through the handle seat channel and firmly abut against the pot lid, thus achieving reliable fixation between the valve cap seat and the pot lid. This ensures the stability of the pressure relief valve and related components during the pressure relief process, preventing loosening or displacement due to vibration or steam impact, thereby improving the overall sealing and safety of the pressure pot lid.

[0013] Furthermore, it also includes a valve cap seat decorative piece, which is disposed on the handle seat and covers the connection gap between the channel opening and the valve cap seat.

[0014] By adding a decorative piece to the valve cap seat on the handle, the connection gap between the valve cap seat and the channel opening can be effectively covered. This not only enhances the overall aesthetics of the lid, but also prevents debris, oil, or moisture from entering the gap and causing dirt buildup or corrosion. It also facilitates daily cleaning and maintenance and extends the product's lifespan.

[0015] Furthermore, it also includes a knob, a left clamp, a right clamp, and a transmission assembly for converting rotary motion into linear motion. The handle base is provided with a lifting handle, and the knob is rotatably mounted on the lifting handle. The left clamp is provided with a left connecting part, and the right clamp is provided with a right connecting part. The knob, the left connecting part and the right connecting part are respectively connected to the transmission component. The rotation of the knob drives the left clamp and the right clamp to clamp or open through the transmission component.

[0016] By setting a knob on the handle, along with left and right clamps and a transmission component that converts rotational motion into linear motion, users can drive the clamps to clamp or release synchronously simply by rotating the knob. This simplifies the locking and unlocking operation of the lid and the pot body, improves the convenience and reliability of operation, and ensures a more stable connection between the lid and the pot body, thus enhancing safety during use.

[0017] Furthermore, the knob is provided with the button receiving cavity. By directly setting the button receiving cavity on the knob, the knob has the dual functions of controlling the clamp locking and triggering the pressure relief button, reducing the number of independent button openings on the lid, making the structure more compact and simple, helping to reduce manufacturing and assembly costs, while improving the overall integration and aesthetics.

[0018] Furthermore, the knob is equipped with a decorative ring and a decorative piece. By adding a decorative ring and a decorative piece to the knob, not only can the visual aesthetics of the knob and the overall lid be enhanced, but it can also serve to prevent dust and water from entering and protect the internal components. This prevents dust or water from accumulating at the connection between the knob and the transmission components, which could lead to poor rotation, thereby improving product durability and user experience.

[0019] Furthermore, it also includes a rotating shaft. The bottom of the handle seat is provided with a lower extension plate, the lower extension plate has a first insertion hole, and the lower extension plate and the lower extension plate form a movable cavity. The transmission component is provided with an upper extension plate, the upper extension plate has a second insertion hole, the upper extension plate extends into the movable cavity, and the rotating shaft passes through the first insertion hole and the second insertion hole in sequence. The transmission component rotates around the rotating shaft as the rotation center.

[0020] By setting a lower extension plate at the bottom of the handle seat to form a movable cavity, and combining it with the insertion structure of the upper extension plate and the rotating shaft, the transmission component can rotate flexibly around the rotating shaft as the rotation center, thereby achieving precise driving and reliable reset of the pressure relief valve.

[0021] The beneficial effects of this utility model are as follows: This invention features at least two accommodating cavities and corresponding pressure-limiting valves on the pot lid. A button-driven transmission component simultaneously lifts multiple pressure-limiting valves, allowing steam to escape synchronously through dual channels. This significantly improves pressure relief efficiency, shortens venting time after cooking, reduces user waiting time to open the lid, and dramatically enhances the cooking experience. Furthermore, the dual venting paths create redundant pressure relief pathways; even if one channel is blocked, the other can still release pressure normally, enhancing safety and reliability during use.

[0022] This utility model discloses a pressure-limiting valve structure with a cover and a plug at the exhaust outlet. In a non-depressurized state, the plug can be inserted into the exhaust outlet to achieve effective sealing and prevent accidental steam leakage. When the user presses the button to trigger the transmission mechanism, the pressure-limiting valve is pushed upwards, causing the cover and plug to retract from the exhaust port, thus smoothly opening the exhaust channel. After depressurization, releasing the button causes the pressure-limiting valve to automatically move downwards and reset under gravity, allowing the plug to re-insert into the exhaust port and seal the exhaust channel. The entire opening and closing process requires no manual valve adjustment, ensuring safety, reliability, and ease of use for subsequent applications.

[0023] This utility model integrates the functions of a handle, knob, clamp, and button into a pot lid handle base. Users can quickly lock and unlock the pot lid by turning the knob to drive the clamp, safely lift and release the pot lid by the handle, and quickly release pressure by pressing the button. The operation is convenient and avoids direct contact with high-temperature steam or the valve body, improving the comfort and safety of use. Combined with the valve cap base and decorative parts design, the overall structure of the pot lid is compact, beautiful and easy to clean, while reducing production and assembly costs.

The transmission component 3 includes a pressing part 31 and a pushing part 32. The transmission component 3 is rotatably mounted on the pot lid 1. The pushing part 32 extends through the opening 111 into the corresponding accommodating cavity 11 and abuts against the corresponding pressure limiting valve 4. The button 2 is pressed down on the pressing part 31, which causes the transmission part 3 to rotate and the pushing part 32 to push the pressure limiting valve 4 upward, so that the pressure limiting valve 4 opens the exhaust pipe 5.

[0038] Furthermore, the pressure relief valve 4 has an exhaust passage 41, and a cover 42 is provided at the outlet of the exhaust passage 41. The cover 42 has an exhaust port 421 that communicates with the exhaust passage 41, and the cover 42 is provided with a blocking part 422. The exhaust pipe 5 passes through the exhaust passage 41 and abuts against the cover 42. When the blocking part 422 is inserted into the outlet of the exhaust pipe 5, the blocking part 422 closes the exhaust pipe 5. When the blocking part 422 leaves the outlet of the exhaust pipe 5, the exhaust pipe 5 is opened.

[0039] Furthermore, it also includes a handle seat 6, which has a channel opening 61 corresponding to the position of the accommodating cavity 11. The exhaust pipe 5 is connected to the pot lid 1, the inlet of the exhaust pipe 5 extends into the pot lid 1, the handle seat 6 is fixed on the pot lid 1, and the outlet of the exhaust pipe 5 extends into the corresponding accommodating cavity 11 and extends towards the corresponding channel opening 61.

[0040] Furthermore, it also includes a valve cap seat 7, which has the receiving cavity 11. The valve cap seat 7 is disposed on the handle seat 6, and the receiving cavity 11 passes through the corresponding channel opening 61 and abuts against the pot lid 1.

[0041] Furthermore, it also includes a valve cap seat decorative piece 8271, which is disposed on the handle seat 6 and covers the connection gap between the channel opening 61 and the valve cap seat 7.

[0042] Furthermore, it also includes a knob 8, a left clamp 9, a right clamp 10, and a transmission assembly 100 for converting rotary motion into linear motion.

The left clamp 9 is provided with a left connecting part 91, and the right clamp 10 is provided with a right connecting part 101. The knob 8, the left connecting part 91 and the right connecting part 101 are respectively connected to the transmission assembly 100. The rotation of the knob 8 drives the left clamp 9 and the right clamp 10 to clamp or open through the transmission component 3.

[0043] Furthermore, the knob 8 is provided with the button receiving cavity 12.

[0044] Furthermore, the knob 8 is provided with a decorative ring 81 and a decorative piece 82.

[0045] Furthermore, it also includes a rotating shaft. The bottom of the handle seat 6 is provided with a lower extension plate 63, the lower extension plate 63 has a first insertion hole 631, and the lower extension plate 63 and the lower extension plate 63 form a movable cavity 64.

[0046] When using the pressure cooker lid 1 of this invention, the user can easily lift or place the lid 1 using the handle 62. When closing or removing the lid 1, simply rotate the knob 8 on the handle 62 to drive the transmission component 100 to simultaneously clamp or release the left clamp 9 and right clamp 10, achieving a secure lock or quick unlocking of the lid 1 and the pot body. The operation is simple and effortless. When pressure relief is required, the user does not need to directly touch the high-temperature pressure relief valve 4 body. Simply press down the button 2 on the knob 8 with your finger. After the button 2 is pressed down, it drives the pressing part 31 of the transmission component 3 to rotate, causing the pushing part 32 of the transmission component 3 to simultaneously lift the two pressure relief valves 4. After the pressure relief valve 4 is pushed up, it is removed from its initial position of sealing the outlet of the exhaust pipe 5 under the action of gravity. The blocking part 422 of the cover 42 that was originally embedded at the outlet of the exhaust pipe 5 moves up with the pressure relief valve 4 and exits the exhaust pipe 5 outlet. The exhaust passage 41 is fully opened, and the steam in the pot can be quickly and safely discharged through the two exhaust passages 41. After the pressure is released, the user releases button 2, and the pressure relief valve 4 automatically moves down and resets under gravity. The cover 42 and the blocking part 422 are reinserted into the outlet of the exhaust pipe 5 and the exhaust passage 41 is sealed, restoring the sealing state and preparing for the next cooking. The whole process is safe, efficient and requires no complicated operation.
