Description

Technical Field

[0001] This utility model relates to the technical field of pressure cooker accessories, and in particular to a detachable pressure cooker lid. Background Technology

[0002] A pressure cooker is a cooking utensil that uses a sealed container and the principle that water's boiling point increases under high pressure to raise the temperature inside the pot above normal cooking temperatures, thus speeding up the cooking process. Pressure cookers are typically made of stainless steel or aluminum and have a sealed lid equipped with a safety valve and pressure regulating device to ensure that the pressure remains within a safe range during cooking.

[0003] The pressure cooker lid is an important component of a pressure cooker. A pressure cooker lid typically includes a sealing ring, a safety valve, a pressure regulating valve, a latch or knob, a pressure limiting valve, and a handle. The pressure limiting valve is the most commonly used part for regulating gas pressure during the use of a pressure cooker. When the gas pressure inside the pot rises to a certain level, it will push up the pressure limiting valve, thereby releasing the pressure inside the pot.

[0004] The existing pressure relief valve is placed directly on an exhaust rod, which is fixed to the pressure cooker lid by a nut. When disassembling the pressure relief valve, other tools are needed to remove the nut, making it inconvenient to use. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a detachable pressure cooker lid, including a lid body 1. A pressure limiting valve 3 is provided on the upper surface of the lid body 1. A fixing component 2 is provided between the pressure limiting valve 3 and the lid body 1. An anti-blocking component 4 is provided on the lower surface of the lid body 1. The fixing component 2 includes a fixing plate 204 fixedly connected to the upper surface of the lid body 1. Several pressing blocks 203 are slidably connected inside the fixing plate 204. A rotating block 202 is threadedly connected inside the fixing plate 204. An exhaust rod 201 is inserted inside the fixing plate 204. The pressure limiting valve 3 is inserted into the top of the exhaust rod 201. A limiting plate 205 is fixedly connected to the outer surface of the exhaust rod 201.

[0030] Specifically, the bottom end of the exhaust rod 201 passes through the fixed plate 204, the pot body, and the lifting plate 401 in sequence. The lower surface of the rotating block 202 and the upper surface of the extrusion block 203 are provided with mutually cooperating inclined surfaces. The interior of the fixed plate 204 is provided with a limiting protrusion for the sliding of the extrusion block 203. The lower surface of the extrusion block 203 is provided with a groove that cooperates with the limiting protrusion. The lower surface of the extrusion block 203 is provided with a slot that cooperates with the limiting plate 205. The inner side of the extrusion block 203 is provided with an arc-shaped surface that cooperates with the exhaust rod 201. The outer surface of the arc-shaped surface is provided with a soft abutment block for sealing.

[0031] Further, rotating block 202 is rotated, causing it to rise inside fixed disk 204. After rising, the inclined surface of the lower surface of rotating block 202 contacts the inclined surface of the outer surface of pressing block 203, thereby releasing the locking of pressing block 203 on the limiting disk 205 on the outer surface of limiting rod. Then, the pressure limiting valve 3 and the exhaust rod 201 are pulled out sequentially upwards, thereby disassembling the pressure limiting valve 3 and the exhaust rod 201. To replace the exhaust rod 201, insert the exhaust rod 201 into the round hole inside fixed disk 204. When the limiting block... When 404 abuts against the outer surface of the extrusion block 203, the extrusion block 203 is squeezed to the outside by the arc surface of the outer surface of the extrusion block 203, so that the limiting block 404 can pass through. At this time, the rotating block 202 is rotated, so that the rotating block 202 descends in the fixed plate 204, so that the extrusion block 203 is squeezed by the inclined surface of the outer surface of the rotating block 202, and the limiting block 404 is locked by the extrusion block 203, thereby locking the exhaust rod 201. Furthermore, the soft abutting block on the outer surface of the extrusion block 203 abuts against the outer surface of the exhaust rod 201, thereby achieving a seal.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The anti-blocking component 4 includes a fixing ring 403 fixedly connected to the lower surface of the cover 1. The inner side of the fixing ring 403 is threadedly connected to an anti-blocking cover 402. The inner side of the fixing ring 403 is slidably connected to a lifting plate 401. A sealing ring 405 is provided on the upper surface of the lifting plate 401.

[0034] Specifically, the inner side of the fixing ring 403 is provided with a sliding groove, and the outer side of the lifting plate 401 is fixedly connected with a limiting block 404 that cooperates with the sliding groove. The inner side of the round hole inside the lifting plate 401 for the exhaust rod 201 to pass through is provided with a groove for placing the sealing ring 405.

[0035] Furthermore, the anti-clogging cover 402 is connected to the fixing ring 403 by a thread, allowing the anti-clogging cover 402 to be rotated and disassembled. The new anti-clogging cover 402 is rotated and lifted into the interior of the fixing ring 403. When the anti-clogging cover 402 is lifted, it drives the lifting plate 401 to rise, thereby driving the sealing ring 405 on the upper surface of the lifting plate 401 to seal the round hole through which the exhaust rod 201 is inserted, further improving the sealing effect.

[0036] Working principle: When it is necessary to disassemble the pressure relief valve 3 of the pressure cooker lid, rotate the rotating block 202, causing it to rise inside the fixed plate 204. After the rotating block 202 rises, the inclined surface of the lower surface of the rotating block 202 contacts the inclined surface of the outer surface of the pressing block 203, thereby disengaging the pressing block 203 from the locking plate 205 on the outer surface of the limiting rod. Then, pull out the pressure relief valve 3 and the exhaust rod 201 in sequence to disassemble them. To replace the exhaust rod 201, insert it into the round hole inside the fixed plate 204. When the limiting block 404 abuts against the outer surface of the pressing block 203, the pressing block 203 is squeezed to the outside by the arc surface of the outer surface of the pressing block 203, allowing the limiting block 404 to pass through. At this time, rotate the rotating block 202, causing it to move inside the fixed plate 204. The pressure cooker descends, causing the inclined surface of the outer surface of the rotating block 202 to press the compression block 203. The compression block 203 locks the limiting block 404, thereby locking the exhaust rod 201. The soft abutment block on the outer surface of the compression block 203 abuts against the outer surface of the exhaust rod 201, achieving a seal. After replacing the exhaust rod 201, the anti-blocking cover 402 at the bottom of the lid 1 is replaced. The anti-blocking cover 402 is connected to the fixing ring 403 by threads, allowing the anti-blocking cover 402 to be rotated and disassembled. The new anti-blocking cover 402 is rotated and lifted into the interior of the fixing ring 403. When the anti-blocking cover 402 is lifted, it drives the lifting plate 401 to rise, thereby causing the sealing ring 405 on the upper surface of the lifting plate 401 to seal the round hole through which the exhaust rod 201 is inserted, further improving the sealing effect. Finally, the exhaust rod 201 of the pressure cooker lid is removed and replaced.
