Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an opening and closing structure of a pressure cooker cover. Background Art

[0002] Pressure cookers are widely used as a cooking tool because they can speed up cooking by increasing pressure. The traditional pressure cooker design usually includes a sealed pot body and a lid that can seal the pot body. The lid usually has a vent hole for releasing steam during cooking and a safety valve for releasing pressure when the pressure exceeds the safety threshold to maintain the pressure within a safe range.

[0003] The existing pressure cooker lid usually requires the user to rotate the lid to align with the corresponding notch on the pot body to achieve sealing. Although this structure is easy to operate, it is not safe and convenient, especially in one-handed operation or in a slippery environment, so it is necessary to make improvements to the above problems. Summary of the invention

[0038] Preferably, the clamp assembly 100 further includes a safety valve 17 , which cooperates with the short connecting piece 111 and the long connecting piece 112 , and a positioning pin 5 and a positioning pin spring 4 are further provided in the knob 3 .

[0039] Preferably, a guide plate 13 is provided on the lower side of the short connecting piece 111, and the guide plate 13 cooperates with the short connecting piece 111 and the long connecting piece 112. An aluminum sleeve 14 is provided in the middle of the guide plate 13, and a positioning column 15 is provided in the middle of the pot cover body 18, and the aluminum sleeve 14 cooperates with the positioning column 15.

[0040] Preferably, the clamp assembly 100 further includes a clamp panel 7, wherein the clamp panel 7 covers the short connecting piece 111 and the long connecting piece 112, and the knob 3 is provided with a knob cover 2, and the knob cover 2 is provided with a knob crystal piece 1.

[0041] Preferably, the pressure limiting valve assembly 200 includes an outer valve body 22, an inner valve body 23, an exhaust pipe 24, and a pressure limiting valve panel 26 which are connected in sequence; the pressure limiting valve panel 26 is fixed to the pot cover body 18; an outer valve body sleeve 21 is provided on the outer valve body 22; a valve cap 20 is provided on the outer valve body sleeve 21; a stainless steel gasket 25 is provided between the exhaust pipe 24 and the pressure limiting valve panel 26; the lower side of the exhaust pipe 24 passes through the pressure limiting valve panel 26 and is connected in sequence to an aluminum gasket 27, an exhaust pipe O-ring 28, and an anti-blocking nut 29.

[0042] Preferably, the pressure-limiting valve assembly 200 is provided with a secondary pressure-limiting valve 16 , and the secondary pressure-limiting valve 16 is located on the pot cover body 18 .

[0043] Preferably, the indicator cap assembly 300 includes an indicator cap 30, a bolt 31, and an indicator cap panel 34 connected in sequence, an indicator cap insert 33 and an indicator cap spring 32 are arranged in the bolt 31, a clamping nut 36 is arranged on the lower side of the indicator cap panel 34, the bolt 31 passes through the indicator cap panel 34 and is connected to the clamping nut 36, an indicator cap O-ring 35 is arranged between the bolt 31 and the clamping nut 36, and an indicator cap sealing seat 37 is arranged on the lower side of the clamping nut 36.

[0044] Preferably, a sealing ring 19 is disposed inside the pot cover body 18 .

[0045] When in use, the knob 3 is rotated to drive the gear 6 to rotate, and then drive the racks on the short connecting piece 111 and the long connecting piece 112 to make the left clamp 101 and the right clamp 102 move to the two ends to achieve the cover opening position.

[0046] When the lid is in the closed position, the pressure in the pot rises, and the safety valve 17 is pushed up and sealed by the pressure in the pot, and starts to work. At this time, if you want to open the pot lid, the head end of the long connecting piece 112 will get stuck in the aluminum part of the safety valve, so that it cannot be opened. When the lid is in the open position, the long connecting piece 112 is under the knob 3 of the knob, and the head end will prevent the aluminum part of the safety valve 17 from rising, and the gas in the pot will be discharged from the safety valve 17.

[0047] The function of the pressure limiting valve assembly 200 is to adjust the pressure by turning the outer valve body sleeve 21 to control the release of the pressure in the pot, thereby maintaining the pressure in the pot within a safe range. The function of the indicator cap assembly 300 is to effectively see which gear the current pressure is at.

[0048] The detachable function of the clamp assembly 100 can also be realized. After the screw 38 is unscrewed counterclockwise, the button 8 is pressed and the knob 3 is rotated at the same time. The knob 3 is rotated to the bottom, and the knob 3 drives the rollers 12 on the left clamp 101 and the right clamp 102. The rollers 12 move 8 mm in the direction of the button 8, which greatly increases the opening of the left clamp 101 and the right clamp 102, making it easier to remove the clamp assembly 100.

[0049] After cleaning the pot cover body 18 and the clamp assembly 100, when installing the clamp assembly 100 again, keep the knob 3 in the open state, align the safety valve hole on the clamp assembly 100 with the valve cap on the safety valve 17, and then align the aluminum sleeve 14 on the clamp assembly 100 with the positioning column 15 on the pot cover body 18 and press it. When the left clamp 101, the right clamp 102 and the pot cover body 18 are in contact, turn the knob 3 clockwise to the end, and then tighten the screw 38 to complete the installation, so that quick and convenient disassembly and assembly can be achieved, and it is easier to clean.

[0050] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
