[0025] The anti-blocking component 7 is fixedly installed on the inner side of the pressure relief partition 5, and the anti-blocking component 7 is used for cleaning the pressure relief hole 6;

[0026] The quick release assembly 8 is fixedly installed inside the lid handle 2 and is used for quick disassembly and assembly of the lid handle 2 .

[0027] A safety valve 101 and an alarm valve 102 are fixedly installed on the inner ring of the top of the cover body 1, and multiple groups of reinforcing ribs 103 are fixedly welded on the outer ring of the top of the cover body 1. The safety valve 101 is a fusible piece type. When the temperature in the pot increases with the pressure, when the warning pressure is reached, the fusible piece is damaged and the pressure in the pot is released. The principle of the alarm valve 102 is similar to that of the pressure relief valve 3. Its pressure is higher than the former. It works when the warning pressure is reached, thereby ensuring the safe operation of the pressure cooker. The design of the reinforcing ribs 103 on the top of the cover body 1 improves the structural strength of the cover body 1, and will not deform even if the pressure in the pressure cooker is too high, thereby effectively improving the anti-deformation effect of the cover body 1.

[0028] A plurality of closing buckles 104 are fixedly connected to the bottom of the cover body 1, and a rubber sealing ring 105 is fixedly connected to the inner side of the cover body 1 and the outer ring of the pressure relief partition 5. When the cover body 1 is closed on the pressure cooker, the plurality of closing buckles 104 are buckled with the pressure cooker and cooperate with the rubber sealing ring 105 on the inner side to ensure the sealing effect of the cover body 1.

After the lid handle 2 is fixedly installed on the outer side of the lid body 1 through the metal connecting strip 4, the fitting portion 201 at the rear end of the lid handle 2 is fitted with the lid body 1. Since there is a contact surface between the rear end of the lid handle 2 and the lid body 1, it is more stable when the lid handle 2 is lifted to open the lid body 1. At the same time, the design of the anti-slip grooves 202 at the front end of the lid handle 2 can prevent slipping when grasping.

[0030] The anti-blocking component 7 includes a rotating shaft 701 rotatably connected to the center of the cover body 1, a knob 702 is fixedly connected to the top of the rotating shaft 701, a connecting block 703 is fixedly connected to the bottom of the rotating shaft 701, two groups of shovel plates 704 are symmetrically connected to the outer side of the connecting block 703, and the inner sides of the two groups of shovel plates 704 are in contact with the pressure relief partition 5, and scraping grooves 705 are provided inside the shovel plates 704. If the pressure relief hole 6 on the pressure relief partition 5 is blocked due to improper operation, it can be observed that the pressure relief valve 3 cannot exhaust and relieve pressure. At this time, rotating the knob 702 drives the rotating shaft 701 to rotate, so that the shovel plates 704 on the outer side of the connecting block 703 shovel the blockage on the outer side of the pressure relief hole 6, and the blockage is shoveled away from the outer side of the pressure relief hole 6 through the scraping grooves 705 on the inner side of the shovel plates 704, thereby preventing the pressure in the pressure cooker from increasing and being unable to relieve pressure, thereby further improving the safety of the cover body 1.

After the air pressure inside the pressure cooker increases, it is exhausted through the pressure relief hole 6 on the pressure relief partition 5, and then the pressure is relieved through the pressure relief valve 3. If the pressure relief hole 6 on the pressure relief partition 5 is blocked due to improper operation, it can be observed that the pressure relief valve 3 cannot exhaust and relieve pressure. At this time, the knob 702 is turned to drive the rotating shaft 701 to rotate, so that the shovel plate 704 on the outside of the connecting block 703 shovels the blockage outside the pressure relief hole 6. The blockage is shoveled from the outside of the pressure relief hole 6 through the scraping groove 705 on the inside of the shovel plate 704, thereby preventing the air pressure in the pressure cooker from increasing and being unable to relieve pressure. 4, the pressing block 803 is pushed up, and the fixing columns 807 on the two sets of sliders 805 are inserted into the fixing holes 809 under the transmission of the connecting rod 806, so that the cover handle 2 is fixed when it is sleeved on the outside of the metal connecting strip 4, ensuring the normal use of the cover handle 2. When the cover handle 2 is damaged, it is only necessary to press the button 802 to drive the pressing block 803 to be steadily pressed down under the connection of the sliding rod 808, and then pull the two sets of sliders 805 through the connecting rod 806 to make the fixing columns 807 disengage from the inner side of the fixing holes 809, thereby releasing the fixation between the cover handle 2 and the metal connecting strip 4, and then quickly disassemble and replace the cover handle 2. The whole operation process is simple and convenient, which can improve the overall anti-deformation effect and use safety of the anti-deformation pot cover for the pressure cooker, and at the same time greatly improve the convenience of disassembling and replacing the cover handle 2.
